It aims at examining other characters' verbal responses to Hamlet’s impolite speech acts and identifying which response strategies are more frequently associated with which impoliteness strategies. To achieve these objectives, the study collates (32) impolite speech acts along with their responses from Hamlet to represent its data for analysis. Out of these data, (15) examples are randomly selected to analyze the impoliteness strategies utilizing Culpeper’s (1996/2011/2017) and Culpeper, Bousfield and Wichmann (2003) models. Moreover, Bousfield’s (2008) model was adopted to account for the interlocutors' responses to impoliteness. The findings of the study show that mock impoliteness, bald on record impoliteness and positive impoliteness are repeated in the play, of which mock impoliteness is the most frequently used strategy. Concerning the response strategies, the defensive and defensive-offensive strategies are frequently used by the characters in Hamlet, but the most frequent one is the defensive strategy. These impoliteness strategies and their responses have adversely affected the relationship amongst characters in the play and its general atmosphere. © 2022 JJMLL Publishers/Yarmouk University.

Moreover, the cooling coil is characterized by a highly nonlinear dynamic subject to multiple inputs, coupling between the latent and sensible heat transfer modes, uncertain disturbances, and strong dependence of the overall heat transfer coefficient on the flow type, all causing significant challenges when it comes to modeling. Therefore, a hybrid layer structure model was adopted in this study to overcome these challenges. The new approach used two different optimization methods, Neural Networks' Weights and Takagi-Sugeno (TS) fuzzy, and the hybrid layers tuned by the Gauss-Newton algorithm (GNA). The proposed model covered three types of fluid flow to represent the dynamic behavior of the water-side and air-side heat transfer coefficients, each of which was divided into seven clusters and had its unique TS consequence. This study also administered meaningful fitness tests in the responses of the eleven independent variables that serve as its inputs. Furthermore, its application shows the control performance saving more than 44% of HVAC system energy. Based on the results, it was concluded that the proposed model is suitable for estimating energy and cost savings for electric power and water flow rate efficiency. In addition, the response of all types of output flow can be evaluated when changing eleven independent variables that are manipulated by three different controllers. © 2022 Elsevier Ltd | Elsevier Ltd | 13640321 | |

To efficiently optimize such a complicated solution, the creation of a high-precision optimization algorithm is critical. Hence, this research proposes a Multi-strategy Slime Mould Algorithm (MSMA) to determine the optimal operating rules for a complicated hydropower multiple reservoir prediction problem. The MSMA system proposed employs an effective wrap food mechanism to strengthen local and global capability; an enhanced solution quality (ESQ) to promote solution quality; and the interior-point method to implement an influential exploitation mechanism. The numerical testing of 23 test functions demonstrates the efficiency of the MSMA algorithm in solving global optimization issues. The newly developed method is then used to optimize the operation of a complex eight-reservoir hydropower system, with the proposed MSMA approach resulting in ∼0.999% of an ideal global solution, according to the optimal findings. The results of the multi-reservoir system show that proposed MSMA method was able to generate about 16.6% more power than the SMA. Consequently, the recommended method outperforms the other well-known optimization methods for maximizing power in the multi-reservoir system. Finally, this study also provides a useful tool for optimizing the complicated hydropower multiple reservoir problems. © 2022 Elsevier B.V. | Elsevier B.V. | 9507051 | |

The density matrix equations, coupled with the continuity-current equation, are solved numerically to address the interaction between all the states, which is impossible with the rate equation modeling. This modeling allowed us to obtain quantum efficiency (QE). Using the orthogonalized plane wave assumption for WL-QD, the momentum matrix elements of QD-QD, QD-wetting layer (WL), WL-barrier transitions are calculated. Results are simulated in both the excitonic and non-excitonic (electron-hole, eh) cases and exhibit the importance of adding the QD layer. The results confirm the importance of adding the intermediate band (QD layer). Both band-to-band recombination rates and relaxation rates in the DQD structure are modulated according to the energy difference between DQD states. Compared to the eh model, the excitonic model reduces the QD-QD relaxation rates and all band-to-band recombination rates. The quantum efficiency (QE) is attaining at longer recombination and relaxation times that are confirmed depending on the wider energy difference by manipulating the transitions of the DQD structure. © 2022 Elsevier Ltd | Elsevier Ltd | 27730123 | |

In this work, three types of ZnO-CdS composites have been synthesized and applied as photocatalysts for the degradation of Rhodamine B dye in aqueous solutions. The optical and morphological properties of the prepared composites were characterized by different techniques. X-ray diffraction patterns used to identify the phase and to calculate the crystallites size of composites. The morphology and particle size of the composites were analyzed by transmission electron microscopy (TEM). Energy Dispersive X-Ray Analysis coupled with transmission electron microscopy used to measure the composites elemental content. Electronic and optical properties of the solid composites were analyzed by diffraction spectrophotometer. TEM results revealed that all ZnO-CdS composites have homogenous shape with (20-30 nm) particles size. XRD characterization indicates that the composites pattern belongs to wurtzite structure and the calculated crystallites size also in the nanometer. EDS results revealed that all ZnO-CdS composites contains only oxygen, Zinc, Cadmium and sulfur without impurities. UV-Vis measurements showed that the energy-gap of composites significantly decreased after heat treatment and all of prepared composites absorb visible light. The photocatalytic activity of prepared composites shows an excellent performance for RhB dye degradation in aqueous solutions. © 2019 National Information and Documentation Center (NIDOC) | NIDOC (Nat.Inform.Document.Centre) | 4492285 | |

Investigate hypoxia status by measuring the concentration of HIF-1α as a prognostic factor of hypoxia and its relation to tumor suppressor protein p53, estradiol, tumor grade, tumor size, and lymph node metastases of adult female with breast cancer. This study is a case control study which includes sixty-five adult female patients with breast mass. Out of 65 patients, a 44 (68%) were with fibroadenoma in the age range of 18-42 (32.55±6.40) and the other 21 (32%) cases with breast cancer type invasive ductal carcinoma (IDC) aged 32-80 (56± 14.4). Most IDC cases were in grade III and sizes T2 and T3. The other 50 healthy females, as a control group were in mean age of 44.56±16.85. Preoperative blood samples were collected for biochemical analysis by the ELISA method. A significant elevation in serum HIF-1α, P53 and E2 (p<0.001) in IDC cases as compared to fibroadenoma and the control group, there was a positive relation between HIF-1α, P53, and E2. HIF-1 α, P53, and E2 were significantly elevated in the patients with grade III and tumor stage T3 than grade II and stages T2 and T1. A significant elevation was found in the subgroup of positive LNM for all preoperative serum levels of parameters compared with the negative LNM patients group. HIF-1α, p53, and E2 were useful markers of invasion depth of tumor or LNM in breast cancer staging and the interactions between HIF-1α, p53, and E2 signaling pathways may be of major clinical significance in cancer therapies through targeting the lowering of severity of hypoxia and angiogenesis.

The importance of these techniques has grown significantly as various real-life applications in fields like medicine, banking, or transport are accompanied by increasing security concerns. Various effective cryptography schemes were proposed so far in the literature; however, each of them exhibits certain flaws and limitations with respect to different vital aspects. To overcome these issues, we propose a hybrid scheme for securing digital images by encrypting them using a dual security approach. More precisely, we use first a chaotic map for scrambling the image pixels, and then, we apply the singular-value decomposition method for decomposing the permuted image to provide very strong security. Individually each of these steps has already been considered in the cryptographic literature; however, their combination has not been proposed before this contribution. Experimental results on benchmark data validate our proposed scheme and various performance evaluation metrics indicate that it shows promising qualities in terms of security (against various attacks) and sensitivity in comparison with baseline methods. © 2022 The Author(s) | Elsevier Ltd | 25900544 | |

Methods: Different concentrations of the ZnNPs (50, 100, and 200 μg/ml) alone and combined with albendazole (ALZ, 100 μg/ml) were treated with hydatid cyst protoscoleces obtained from liver of infected sheep for 5–60 min in vitro and ex vivo. Eosin exclusion examination was used to assess the viability of protoscoleces. The induction of apoptosis in hydatid cyst protoscoleces was assessed by measurement of the Caspase-3 activity of protoscoleces treated with various concentrations of ZnNPs. Results: The size of green synthesized ZnNPs was ranged from 30 to 80 nm, most of these nanoparticles were between 50 and 60 nm in size. In vitro, the highest scolicidal effect of ZnNPs was observed at the concentration of 200 μg/ml, where it killed 81.6% of protoscolices. While the combination of these nanoparticles with ALZ, especially at the concentration of 200 μg/ml, completely killed the protoscolices after 10 min’ exposure. However, compared to in vitro assay, the drugs tested took longer to show their protoscolicidal effect. Conclusion: Based on the obtained results, ZnNPs particularly in combination with albendazole displayed the potent protoscolicidal in vitro and ex vivo as an intraperitoneal model of administration of agents to hydatid cyst treatment; nevertheless, additional investigations are mandatory to evaluate the efficacy and safety Zn NPs as a favorable protoscolicidal agent in clinical setting. © 2022 | Elsevier Ltd | 20490801 | |

In this article, the fear of predator in prey species has been introduced. Also, we have considered that the predation of both prey and predator occurs according to the Beddington-DeAngelis type functional response. The predator is thought to be acting as a shelter for the super predator species. It is anticipated that a constant amount of increased food will be delivered to super predators due to their dread of predators and their refuge behavior, and that predators will benefit from this excess food. The non-negativity and boundedness of solutions of the prosed model have been examined. The system's local and global stability at the interior equilibrium points has been explored. The existence condition of Hopf bifurcation of the system with respect to fear f of predator has been studied. From the analysis of the model, it is found that the fear f of predator may be responsible for the system's stability. It's also been discovered that providing extra food to the super predator may help to keep the system in check. Further, it is found that the refuge of predator to the super predator has the ability to stabilize the predator-prey system. Finally, some intriguing numerical simulation findings were provided in order to study the model's dynamics. © 2022 Elsevier Ltd | Elsevier Ltd | 9600779 | |

A superhydrophilicdemulsifier was created by functionalizing nanoparticles with [TBIP] thiadiazole derivative to improve their hydrophobicity and hydrophilicity.Thestructural characteristics and morphology of the prepared nanodemulsifier were investigated by (FT-IR), 1H-NMR, (XRD), (AFM), (FESEM) and (TEM).A bottle test was also used to assess the performance of the nanodemulsifier. The bottle test results revealed that nanocomposite has the highest nanodemulsifier efficiency, and crude oil reduction was accomplished in 90 minutes. Furthermore, the impacts of temperature and concentration revealed that both elements influence the stability of water in an oil emulsion. The separation efficiency of the prepared nanocomposite Fe2O3.B2O3-TBIP was compared with that of the commercial demulsifier (RP96BQ), used in the oil field and under the same conditions. The demulsification percentage of the prepared nanocomposite was (79.3 %) while the commercial demulsifier reached (86.2 %). © 2019 National Information and Documentation Center (NIDOC). | NIDOC (Nat.Inform.Document.Centre) | 4492285 | |

The electronic properties of the anticancer drugs/ZnONS studied by using DFT method, which implemented in the quantum espresso package. Our finding shown that ZnONS has a semiconductor behavior. Interestingly, the electronic band gap of the 5-FU/ZnONS and GB/ZnONS is decreased, but they still have semiconductor behaviors. For 6-MP/ZnONS, it is increased and converted to n-type semiconductor for CP/ZnONS structure. According to acquired findings, the complex structures became more stable and lower reactive due to the total energy of these complex structures is increased compared to pristine ZnONS. We detected that the adsorption of the 6-MP, GB, and CP on the ZnONS is moderate chemisorption and physisorption for 5-FU on the ZnONS, successively. All complex structures are required higher excitation energy to transfer an electron due to the chemical hardness of all complex structures is decreased, but the 6-MP/ZnONS structure has the opposite behavior. There is a weak interaction between ZnONS and (5-FU, 6-MP, and GB) and good interaction between the ZnONS and CP due to the electrophilic of these structures has lower and higher value, respectively. Concisely, ZnONS considered the greatest substrate to carry CP anticancer drug compared to other anticancer drugs. © 2022 | Elsevier B.V. | 5779073 | |

Professor/ Thi Qar University, College of Engineering, Iraq | Geopolymer has been emerged as an innovative and eco-friendly alternative to traditional soil improvement products such as Ordinary Portland Cement (OPC) and lime, which have negative environmental consequences. Geopolymer has been employed in various geotechnical applications as alternative lightweight backfill in highway barriers and/or behind retaining walls, providing technical, environmental, and economic benefits. The present study aims to evaluate the mechanical, durability, and Microstructure properties of clayey soil (with different percentages of sand) stabilized using coal-fired fly and a sodium hydroxide/sodium silicate solution alkali activator. Stabilized soils exhibited high strength of 1–8 MPa compared with less than 0.3 MPa for untreated soils. Moreover, adding sand to clay soil reduced the optimum ratio of alkaline activator from 0.8 for clayey soil with 5% sand to 0.6 for clayey soil with 10, 20, 30% sand. The geopolymer treated samples also showed high resistance to the acidic environments and chlorides. Finally, SEM results revealed a clay fabric modification caused by inter-particle contacts and the resulting bonding caused by gel formation and hardening. According to the outcomes of this study, it can be concluded that using a fly ash geopolymer binder for soil stabilization is a viable alternative to cement in geotechnical applications. © 2022 The Authors | Elsevier Ltd | 22145095 | |

To characterize these phenomena, the researchers used a theoretical approach on the basis of time series and phase space maps, i.e., attractors. In case of coupled QDLED attractors, the phases are generally locked during synchronous regime while the amplitudes are correlated. With the proposed construction scheme, both frequency detuning and coupling strength of two systems can be tuned independently. Further, chaotic attractors with even or else odd count of scrolls can also be easily generated. The study also demonstrated distinct attractors with n scrolls obtained using coupled design. © 2021, The Optical Society of India. | Springer | 9728821 | |

Later, other heterologous combinations of CoronaVac (DB15806), Janssen (JNJ-78436735), CanSino (AD5-nCOV) and other were also being trialled to explore their effectiveness. Previously, such a strategy was deployed for HIV, Ebola virus, malaria, tuberculosis, influenza and hepatitis B to develop the artificial acquired active immunity. The present review explores the science behind such an approach for candidate COVID-19 vaccines developed using 11 different platforms approved by the World Health Organization. METHODS: The candidate vaccines' pharmaceutical parameters (e.g. platforms, number needed to vaccinate and intervals, adjuvanted status, excipients and preservatives added, efficacy and effectiveness, vaccine adverse events, and boosters), and clinical aspects must be analysed for the mix-and-match approach. Results prime-boost trials showed safety, effectiveness, higher systemic reactogenicity, well tolerability with improved immunogenicity, and flexibility profiles for future vaccinations, especially during acute and global shortages, compared to the homologous counterparts. CONCLUSION: Still, large controlled trials are warranted to address challenging variants of concerns including Omicron and other, and to generalize the effectiveness of the approach in regular as well as emergency use during vaccine scarcity. © The Author(s) 2022.

The present study aimed to characterize the spectrum of alpha-globin gene mutations in patients who were followed up in a genetic diseases center in Thi-Qar province. A total of 30 subjects were collected from thalassemia patients and 15 cases as the control group. Polymerase chain reaction (PCR) and direct sequencing were performed for functionally regions of the gene (exon 1 and exon 2). The fragment size amplified was 442 bp in the Exon 1 region and 324 bp in the Exon 2 region of α-globin. The molecular analysis of the sequence of PCR products revealed that 13 point mutation within the α-thalassemia gene included deletion and substitution mutation, while the rest of the mutations were in the intron site of the gene. These results indicated that mutations may constitute a risk of developing hemophilia B disease. Molecular mechanisms in the expression of globin genes are used to help manage patients with thalassemia. © 2022 by Razi Vaccine & Serum Research Institute | Razi Vaccine and Serum Research Institute | 3653439 | |

Therefore, this study aimed to evaluate the association of lactate dehydrogenase (LDH), D-Dimer, vitamin D, and ferritin statuses with the prognosis of COVID-19; moreover, it was attempted to investigate its prevalence according to age, employment status, body mass index (BMI), and place of residency in a population sample of hospitalized patients in Thi-Qar, Iraq. This study evaluated 200 COVID-19 patients and 100 controls. The BMI of all individuals was calculated, and such demographic characteristics as age, gender, place of residency, and occupational status were collected from all participants. Blood samples were taken and used to estimate D-Dimer, LDH, vitamin D, ferritin, oxygen, and pulse rate. The mean age of the patients approached the fifth decade, and 72% of the cases were more than 40 years of age. In addition, 60% of the patients were living in the countryside, and 52% of the participants were employed, compared to only 8% of the cases who were students. The BMI of the patients was obtained at 31.44±10.2 kg/m2; accordingly, 47% and 40% of the cases were obese and overweight, respectively, compared to only 12% of the patients who had normal weight (P<0.05). There were significantly lower vitamin D levels in the patients; however, the concentrations of LDH, serum ferritin, and D-Dimer were significantly higher in the patients, compared to the control group (P<0.05). Not only age and body weight but also employment status and place of residency maybe also the important risk factors for COVID-19 distribution. LDH, D-dimer, vitamin D, and ferritin statuses could be used as good biomarkers for this disease and its severity.

Classification of marshlands in these regions and mapping of their land cover is not an easy task and maps need to be upgraded frequently. Satellites provide enormous amounts of information and data for the continuous monitoring of changes. The aim of this paper is to introduce an approach using multispectral satellite imagery that was adopted to classify and monitor the Al Hammar Marsh (Iraq) over several years and to suggest a relationship between the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Moisture Index (NDMI), and the Normalized Difference Water Index (NDWI), using Landsat 8 data with a resolution of 30 m × 30 m, validated with Sentinel-2 datasets at 10 m × 10 m. Six land cover classes were used: (1) open water, (2) dry area, (3) dense vegetation, (4) medium-density vegetation, (5) sparse vegetation, and (6) wet soil. Three indices, NDWI, NDMI, and NDVI, were chosen for the automatic classification of each pixel and the creation of a time series of land cover maps. The proposed method can efficiently classify and monitor marshlands and can be used to study different marshlands by adjusting the thresholds for NDVI, NDMI, and NDWI. Overall, the correlation for all classes (R) between Landsat 8 and Sentinel-2 is about 0.78. Thus, this approach will help to preserve marshes through improved water management. © 2022 by the authors. Licensee MDPI, Basel, Switzerland. | MDPI | 20734441 | |

A risk prediction task for short-term is big challenge task; however, it is a great importance for recommendation systems in health care field to provide patients with accurate and reliable recommendations. In this work, clustering method and least square support vector machine are used for prediction a short-term disease risk prediction. The clustering similar method is based on euclidean distance which used to identify the similar sliding windows. The proposed model is trained by using the slide windows samples. Finally, the appropriate recommendations are generated for heart diseases patients who need to take a medical test or not for following day using least square support vector machine. A real dataset which collected from heart diseases patient is used for evaluation.

The analysis was performed on hourly wind data over three years for five locations measured with a 10 m-high anemometer in Peninsular Malaysia. The performance of wind turbines with varying hub heights and rated power was examined. The economic evaluation of wind energy in all sites was based on an analysis of the annual Levelized cost of energy. Results show that the annual mean wind speeds vary from 1.16 m/s in Sitiswan to 2.9 m/s in Mersing, whereas annual power varies from 3.6 to 51.4 W/m2. Moreover, the results show that the cost of unit energy varies between (4.5-0.38) $/kWh. The most viable site for the use of wind turbines was Mersing, while Sitiawan was the least viable site. A case study examined three wind turbine models operating at Mersing. The study showed that increasing the inflation escalation rate for operating and maintenance from 0-5% led to a decrease in the unit energy cost by about 38%. However, increasing the operating and maintenance escalation rate from 0-10% led to an increase in the unit cost of energy by about 7-8%. © 2022.

The ligands and their complexes characterized by spectroscopic methods (FTIR, 1H-NMR, MS). The ligand acts as a bidentate ligand coordinating through the nitrogen atom of the oxadiazole ring and the nitrogen atom of amino group. This view is further supported by the appearance of a band corresponding to the metal-nitrogen and vibration at 454–688 cm–1 and 314-466 cm-1 in the complexes, respectively. The magnetic studies suggest a octahedral and square planar geometry of the complexes. The complex of Fe (III) have shown octahedral geometry, the complex of Ni (II) has shown square planar geometry with prepared ligands.HOMO-LUMO molecular orbitals analysis of these ligands (L1,L2) and some quantum chemical parameters derived from frontier molecular orbitals were studied.

Reinforcement learning (RL) is considered a promising technique to solve this problem without an analytical approach, but it has been unable to overcome the awkwardness of an extremely large action space in the real world; it would be quite hard to converge to a set point. The core of the problem with RL is its state space and action space of multi-agent action for building and HVAC systems that have an extremely large amount of training data sets. This makes it difficult to create weights layers accurately of the black-box model. Despite the efforts of past works carried out on deep RL, there are still drawback issues that have not been dealt with as part of the basic elements of large action space and the large-scale nonlinearity due to high thermal inertia. The hybrid deep clustering of multi-agent reinforcement learning (HDCMARL) has the ability to overcome these challenges since the hybrid deep clustering approach has a higher capacity for learning the representation of large space and massive data. The framework of RL agents is a greedy iterative trained and organized as a hybrid layer clustering structure to be able to deal with a non-convex, non-linear and non-separable objective function. The parameters of the hybrid layer are optimized by using the Quasi-Newton (QN) algorithm for fast response signals of agents. That is to say, the main motivation is that the state and action space of multi-agent actions for building HVAC controls are exploding, and the proposed method can overcome this challenge and achieve 32% better performance in energy savings and 21% better performance in thermal comfort than PID. © 2022 Elsevier Ltd | Elsevier Ltd | 3062619 | |

Kx is influenced by several parameters, including river hydraulic geometry, sediment properties, and other morphological characteristics, and thus its calculation is a highly complex engineering problem. In this research, three relatively explored machine learning (ML) models, including Random Forest (RF), Gradient Boosting Decision Tree (GTB), and XGboost-Grid, were proposed for the Kx determination. The modeling scheme on building the prediction matrix was adopted from the well-established literature. Several input combinations were tested for better predictability performance for the Kx. The modeling performance was tested based on the data division for the training and testing (70–30% and 80–20%). Based on the attained modeling results, XGboost-Grid reported the best prediction results over the training and testing phase compared to RF and GTB models. The development of the newly established machine learning model revealed an excellent computed-aided technology for the Kx simulation. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. | Springer Science and Business Media Deutschland GmbH | 9441344 | |

For BGaN and BAlGaN QD structures, matching to AlN, BAlN, AlGaN barriers and also BInGaN/AlN, the wide-bandgap AlN barrier imposes them to emit at 198–202 nm wavelength. For BInGaN QDs matching to the AlGaN, BAlN, the situation is different. They can emit at the range 252−291nm depending on the barrier and the efficiency of boron content in the barrier in redshifting the wavelength is deduced. The TE and TM gain and spontaneous emission spectra are high and increase under increasing boron in the active region or reducing boron content in the barrier region, exceeding its quantum-well counterpart and of central importance in light-emitting diode applications. Ultra-high gain is obtained from BInGaN/BAlN structure. Gain values are arranged according to the bandgap difference (ΔEg). The range of ΔEg is extended, in the studied structures, to ΔEg=1866−2856 meV, which is of practical importance in UV device applications. The total polarization is decreasing for the Al-containing systems, which is preferred. © 2022 Elsevier Ltd | Elsevier Ltd | 13698001 | |

It refers to global warming deterioration in human environmental health and local-global sustainability. This review provides information on the generation and consumption of energy with their air pollution mixture of many pollutants; gases, liquids and particles. These pollutants have become one of the leading environmental hazards to human and planet health. The components of pollutants that result from burning fossil fuels (oil and gas) and coal have been studied, such as sulfur dioxide, carbon dioxide, nitrogen oxides and particles. Both sulfur dioxide and nitrogen oxides interact with water to produce acid rain. Both gas and oil-fired thermal power plants emission today and in the future might be transformed to work on renewable energy sources. The results stated that gas-fired power plants are more generally faster efficient, less pollution than oil and coal power plants. A complete assessment of exhaust gas treatment was conducted. Carbon dioxide capture, desulfurization, denitrification, and particle collection were all successful as treatment control mechanisms. So, previous studies presented some methods for reducing nitrogen oxides and sulfur oxides through water injection and exhaust gas recycling. The addition of nano-additives in diesel emulsion fuel (W/D) has recently been shown to increase the characteristics and performance of the fuel while reducing the quantity of emitted hydrogen chloride (HC) and carbon monoxide (CO). It was determined that the best nano-additives for W/D were Aluminum Oxide (Al2O3), copper(ii) oxide, magnesium oxide (MgO), manganese oxide (MnO), and zinc oxide (ZnO), among others (E10). © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17551307 | |

After about 18 years, very little has been achieved in the restoration process. The inundated areas fluctuate on an annual basis. The water-covered areas increase during wet years and shrink during dry years. One component of the re-marshification is missing; that is a plan based on actual water flow data and supplies. As a result, the vast area of the original marshes is suffering from saline water and ecological deterioration. In this paper, sustained water supplies are specified to restore an area of about 4440 km2, about 55.5% of the marshes area of 1973, and reclaim the salinity problem of Shatt al-Arab. The basic components of the water supplies scheme come from two sources: the first is the environmental flow from the Tigris, the Euphrates, the Karkheh, and the Karun rivers, and the second is the seasonal flows generated along the eastern borderline of Iraq (i.e., The Iraq-Iran Borderline). The proposed scheme requires some engineering works to convey the water flow to the intended Marshes area and isolate Shatt al-Arab from the marshes hydraulically. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17551307 | |

Glycemic control is vital in delaying or preventing complications. Although many people do not take optimal doses, metformin is a cornerstone in managing type 2 diabetes mellitus (T2DM) in all guidelines. This study determined the barriers interfering with optimal metformin dosage. A cross-sectional study was conducted in Thi-Qar Specialized, Diabetes, Endocrine and Metabolism Center (TDEMC) at Thi-Qar, southern Iraq, from January 2019 to January 2020. 475 patients (274 females and 201 males) were included, and examination and lab investigations were performed. Only 22 (4.6%) patients took the optimal dose with no differences between gender. Of those who took metformin, 255 (74%) took it as a regular pill, 79 (23%) as a combined form with sulfonylureas (SUs), while only 10 (0.3%) took combined pills with Dipeptidyl Peptidase-4 inhibitors (DPP4i). 188 patients (65%) took metformin with meals, 84 (29%) before meals, and 19 (6%) after meals. Ignorance caused poor adherence to optimal dose in 165 patients (38.6%), neglect in 75 (17.6%), the cost in 5 (1.2%), 11 patients (2.6%) thought they did not need metformin, 37(8.7%) and 12 (2.8%) blame side effects and shortage of supply from public health care clinics (PHCC) as a cause, respectively. The rest of the patients had more than one cause. The most common side effects were abdominal pain and bloating, 5.9% and 3.8%, respectively. Other side effects were diarrhea in 0.2%, and 7.8% of patients developed more than one side effect. Ignorance and neglect were major obstacles, so educating doctors and patients and supplying the patient with optimal doses through PHCC may overcome the problem. ©2022 JOURNAL of MEDICINE and LIFE. | NLM (Medline) | 18443117 | |

The biological characteristics indices showed an obvious variation in the different stations and seasons. The productivity values in the general estuary, south of Nasiriyah City ranged between 38.99-130.05 mg carbon m-3 hour-1. These values showed two peaks during the fall and spring. The chlorophyll-a and phytovitin-a concentrations ranged between 3-6.44 µg L-1 and 0.66-3.22 µg L-1, respectively. The highest concentrations of both pigments were found in St. 1. In addition, the highest concentration of chlorophyll-a (6.44 mg L-1) during autumn at St. 1, while the highest concentration of phaeophytin-a (3.22 mg L-1) during winter at St. 2.

Artemisia has been studied since time immemorial in several studies all showing its ability in preventing and treating different diseases. However, so far there have been no studies focusing on the possible role of Artemisia in the protection of prostate histoarchitecture toxicity. Therefore, this study aimed to investigate the protective role of Artemisia in the amelioration of histological and hormonal depression affected by sodium fluoride (NaF). A total of 28 male adult Wistar rats were equally divided into four groups (n=7). Animals in the control group received normal saline. The second group received NaF by oral gavage at a dose of 12 mg/kg body weight (B.W.) three times a week. The third group received concurrent treatment with NaF at a dose of 12 mg/kg B.W. three times a week, as well as extraction of Artemisia absinthium at a dose of 100 mg/kg B.W. The fourth group was treated only with extraction of Artemisia absinthium at a dose of 100 mg/k B.W. After 60 days, B.W. and the absolute weight of the prostate were measured. Blood samples and tissues were collected for measuring testosterone, follicle-stimulating hormone, as well as luteinizing hormone concentration, conducting paraffin-embedded sections with hematoxylin, and eosin routine staining. The findings revealed that Artemisia supplement significantly increased body and absolute weight of prostate gland in the group treated by NaF. In addition, mitigating the histological changes throughout the restoration of all prostate components appeared nearly as normal structural tissue. Moreover, the height of glandular epithelium decreased, follicular lumen enlarged, dark secretion materials with homogeneity disappeared of invagination intraluminal, and normal stroma appeared in regular shape. All in all, the results of this study pointed out that Artemisia had a protective effect against NaF-influenced prostate toxicity via stabilizing male hormones, recomposing histoarchitecture, and returning abnormal biomorphic parameters to a nearly normal state.

Due to the Covid pandemic-2019, isolated wards at health care units and even due to the home treated patients; vast quantities of BMW are generated. Covid-19 converts even ordinary waste such as gloves, testing kits, and personal protective equipment into high-risk BMW. The appropriate disposal of such waste involves safety, affordability, and efficacy; hence can be considered a complex issue. A solution proposed in this article is an OSBMWTU (on-site biomedical waste treatment unit) by using microwave radiation. The possibility of enhancing the thermal effect of microwave radiation by using chemical additives was tested. The proposed machine reduces waste volume, inactivates microorganisms, and disposes BMW on-site. Findings suggest that adding butter spray to microwave radiation enhances thermal effectiveness by 43%, increasing treatment temperature while minimizing time, power, and running costs. The proposed machine will work automatically after filling the BMW, thus, minimizing the human involvement. It prevents bio-hazardous waste accumulation and decreases its volume by up to 80%. The designed machine is characterized by safety, low cost, and small dimensions. A machine that can handle 72 kg BMW/day can be set up on-site in an area of 1.5 m2. The suggestion of the proposed machine as a BMW management and treatment system will reduce environmental pollution due to BMW during COVID-19 and even after the pandemic. © The Author 2022.

Furthermore, varying flow analysis is applied to examine the flow resistance, heat transfer, and other design parameters. Our research indicates that heat transfer enhancement can be attributed to two factors. First In corrugated configurations, convective heat transfer is transformed into jet impingement heat transfer. Second, the boundary layer on the leeside of the corrugation was dramatically redeveloped by pulsation. Heat transfer performance is significantly improved and pressure drop is increased due to the spiral flow. Additionally, different corrugated geometrical configurations are used to investigate the flow behaviour based on Nusselt numbers (Nu) and friction coefficients (f) corresponding to the analyse values, and the design parameters such as corrugated ring angle (CRA), corrugated ring diameter (CRD), and a corrugated ring number (NCR). The result indicates that the Nu tend to increase as increases of the Re. The Nu value increases at higher corrugated geometrical configurations increase. Using different corrugated geometric configurations can result in performance superior to smooth pipes because the performance evaluation factor (PEF) value is higher than unity. Both PEF and Re increments, as well as the PEF value, demonstrate a reducing trend. © 2022 The Authors. | Elsevier Ltd | 2214157X | |

The presence of the silver (Ag) metal in the structure makes the valence band Fermi energy deepen. Then, for the plasmonic QD nanolaser (compared to conventional QD laser), the refractive index value doubles while the group velocity is lower by half. The quality factor is increased where high energy can be stored in the cavity. The threshold gain value lowers the material gain by more than ten orders. A comparison with experimental results predicts the possibility of high power applications for this structure. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

Parameter like pH, contact time, methylene blue concentration, and adsorbent dose concentration was studied. Methylene blue removal increased when the dosage of biosorbent increases. Isotherm adsorption was also described by the Langmuir and Freundleich models, It was found that Langmuir isotherm (R2 = 0.9956) is better than the Freundlich model (R2 = 0.9937) which implies that the adsorption of MB on AgNPs-IPN's was monolayer. Thus the maximum adsorption capacities calculated from the Langmuir model was found to be 33.5 mg.g−1 and was consistent with the experimental data. The synthesized AgNPs-IPN's showed an excellent activity towards the removal of methylene blue from synthetic wastewater. ©2022 National Information and Documentation Center (NIDOC) | NIDOC (Nat.Inform.Document.Centre) | 4492285 | |

This paper is an experimental study on steel fiber-reinforced concrete (SFRC) beam specimens strengthened by CFRP against shear than using externally bound reinforcement (EBR) and externally bound reinforcement on grooves (EBROG). Sixteen concrete beams with dimensions of 110 mm width, 150 mm depth, and 1300 mm length were tested to assess the effect of steel fibers and to evaluate the effects of grooving techniques in terms of improving the shear capacities of SFRC beams strengthened by CFRP. The beams were designed to fail via a shear failure mode. Five volume fractions of steel fibers were used: 0.0%, 0.8%, 1.5%, 1.5%* and 2%. The beams are tested under four-point loading with two values of shear span-to-depth (a/d) ratios, which were 2.2 and 2.85. The results show that the shear strength and the ductility increase with increasing fiber volume fraction, and that the load-carrying capacity of SFRC beams increased by 33% to 68% compared to the load-carrying capacity of the control beam (without steel fibers). Also, the test results show that strengthening beams using CFRP sheets enhanced the strength and stiffness of the tested beam specimens. The increase in the load-carrying capacity of SFRC beam strengthened by CFRP sheet using the EBR method was 79%, while the increase in the load-carrying capacity of SFRC beams strengthened by CFRP sheet using the EBROG method ranged from 89% to 110% compared to the control beam. Furthermore, the results show that the shape of the grooves influenced the capacity and the failure mode of the tested beams. Finally, it may be noted that the grooving method has a significant effect on the load-carrying capacity and failure mode in comparison with the EBR method. © 2022 Institution of Structural Engineers | Elsevier Ltd | 23520124 | |

It is a long process, is error prone, and requires a highly trained expert. In this research, a new method is presented for seizure classification for EEG signals using a dual-tree complex wavelet transform (DT-CWT) and fast Fourier transform (FFT) coupled with a least square support vector machine (LS-SVM) classifier. In this method, each EEG signal is divided into four segments. Each segment is further split into smaller sub-segments. The DT-CWT is applied to decompose each sub-segment into detailed and approximation coefficients (real and imaginary parts). The obtained coefficients by the DT-CWT at each decomposition level are passed through an FFT to identify the relevant frequency bands. Finally, a set of effective features are extracted from the sub-segments, and are then forwarded to the LS-SVM classifier to classify epileptic EEGs. In this paper, two epileptic EEG databases from Bonn and Bern Universities are used to evaluate the extracted features using the proposed method. The experimental results demonstrate that the method obtained an average accuracy of 97.7% and 96.8% for the Bonn and Bern databases, respectively. The results prove that the proposed DT-CWT and FFT based features extraction is an effective way to extract discriminative information from brain signals. The obtained results are also compared to those by k-means and Naïve Bayes classifiers as well as with the results from the previous methods reported for classifying epileptic seizures and identifying the focal and non-focal EEG signals. The obtained results show that the proposed method outperforms the others and it is effective in detecting epileptic seziures in EEG signals. The technique can be adopted to aid neurologists to better diagnose neurological disorders and for an early seizure warning system. © 2022 | Elsevier B.V. | 68993 | |

Moreover, they are utilized to evaluate different concentrations of aqueous and alcoholic extracts of Averrhoa bilimbi leaves and antibiotics against bacteria isolated from the oral cavity. This study was conducted simultaneously at the Departments of Botany and Biology, Shatrah Hospital, Thi-Qar, Iraq, during March and August 2021. A. bilimbi leaf extracts were utilized in the plant component examination and the assessment of the antibacterial activity. The bacterial strain of Escherichia coli and Klebsiella pneumoniae was isolated from the oral cavity. To test the antibacterial impact of the extracts on bacteria, the agar well diffusion method was used. The phytochemical screening indicated the presence of Alkaloids, Flavonoids, Sapiens, Steroids, Tannins, Glycosides, and Carbohydrates, followed by the absence of Tannins in aqueous extract. Due to the A. bilimbi leaf aqueous and methanol extract against E. coli, areas of inhibition were found (0.20 cm and 0.19 cm) at the concentration of 100 mg/ml, respectively. However, there were no regions of inhibition of the K. pneumoniae trend for both extracts. The sensitivity of bacterial isolates of E. coli and K. pneumonia to antibiotics was also tested through Gentamicin, Amoxycillin, Azithromycin, Ciprofloxacin, Penicillin, and Polymyxin B, and the regions of inhibition appeared against E. coli (0.5cm, 0 cm, 0.34 cm, 0.45 cm, 0 cm, and 0.12 cm, respectively). Furthermore, the regions of inhibition appeared against K. pneumoniae (3 cm, 0.3 cm, 0.4 cm, 0.55 cm, 0 cm, 0.66 cm, respectively). The antibiotics showed a higher inhibition zone, compared to the aqueous and alcoholic extracts; however, further studies are required to be conducted to validate its reliability. © 2022 Razi Vaccine and Serum Research Institute.

Based on (TiO2) as photoanode, the crystal structure of the basic materials and the prepared nanocompositeWS2QD/TiO2-NC have been studied using X-ray diffraction XRD, as well as the SEM and TEM examination. The physical and chemical properties have proved that the nanocomposite (WS2QD/TiO2-NC) has been produced within a nanoscale. The regular and pure WS2QD particles are successfully installed on the nanocomposite TiO2-NC and exhibit a high surface area and pore size (10μm) when compared to pure WS2QD. The nanocomposite WS2QD/TiO2-NC compound exhibits a PCE conversion efficiency (9.45%), which is relatively high if compared to Pure TiO2 (8.147%). The reason for improving the PCE of (WS2QD/TiO2-NC) is that the presence of MWCNTs and Graphen in the compound reduces the time to reconnect the electron-hole pair and efficiently stabilizes the WS2QD assembly to expose the entire active edges. On the other hand, giving an increase in electrical conductivity facilitates electron transfer inside the compound. Also, the presence of TiO2 improves the ability of the compound to absorb the photon and thus increases the photoelectric stimulation © This work is licensed under the Creative Commons Attribution 4.0 International License | University of Kashan | 22517871 | |

Therefore, AISI4140 steel samples were heat-treated to harden by heating up to 1113 K for 120 min, followed by quenching in agitated mineral oil. Then samples were tempered at 863 K for 60 min. Nitriding was carried out for 1400 up to 21000 min. Samples were characterized by optical microscope, scanning electron microscope, x-ray diffractometer, and HSC thermodynamical software. Results showed that the rate of diffusion was higher in the early stages of nitriding. Due to nitrogen of diffusion, some nitrides are formed in grain boundaries and act as diffusion barriers. In this case, the diffusion mechanism from grain boundary diffusion changes to the volume diffusion or a combination of both mechanisms. Meanwhile, diffusion of nitrogen, in addition to the ferrite layers and grain boundaries, is also performed into the cementite layers. Although these layers are not the preferred areas of diffusion, volume diffusion of nitrogen through cementite layers leads to decomposition of them and turning them into iron nitrides and carbo-nitrides. Results show that almost 42 percent of cementite layers decomposed by nitrogen diffusion. © 2022 IOP Publishing Ltd. | IOP Publishing Ltd | 2051672X | |

Magyarország, Győr, 9024, Hungary; Kovács, T., Donát Bánki Faculty of Mechanical and Safety Engineering, Óbuda University, Budapest, 1081, Hungary | Ti6Al4V (Ti64) alloys manufactured by selective laser melting (SLM) are well known for their susceptibility to failure at a low ductility of less than 10% due to the formation of an (α′) martensitic structure. Annealing and solution treatments as post-heat treatments of α′ are considered a good way to improve the mechanical performance of SLM-manufactured Ti64 parts. In this research, the effect of heat treatment parameters such as temperature (850◦C and 1020◦C) and cooling rate (furnace and water cooling) on the microstructure and mechanical properties of the SLM Ti64 structure was investigated. It was shown that the tensile strength/ductility of the Ti64 alloy produced by SLM was determined by the post-heat treatment. The experimental results revealed that heat treatment at 850◦C followed by furnace cooling resulted in the best possible combination of ductility (13%) and tensile strength (σy = 932, σu = 986 MPa) with a microstructure consisting mainly of 78.71% α and 21.29% β. Heat treatment at 850◦C followed by water cooling was characterized by a reduction in hardness and the formation of predominantly α plus α′′ and a small amount of β. HT850WC exhibited yield and tensile strengths of about 870 and 930 MPa, respectively, and an elongation at fracture of 10.4%. Heat treatment at 1020◦C and subsequent cooling in the furnace was characterized by the formation of an α + β lamellar microstructure. In contrast, heat treatment at 1020◦C and subsequent water cooling formed semi-equiaxial β grains of about 170 µm in diameter with longer elongated α grains and basket-weave α′. Post-treatment at 1020◦C followed by furnace cooling showed high ductility with an elongation of 14.5% but low tensile strength (σy = 748, σu = 833 MPa). In contrast, post-treatment at 1020◦C followed by water cooling showed poor ductility with elongation of 8.6% but high tensile strength (σy = 878, σu = 990 MPa). The effect of aging at 550◦C for 3 h and cooling in a furnace on the microstructure and mechanical properties of the specimens cooled with water was also studied. It was found that aging influenced the microstructure of the Ti6Al4V parts, including β, α, and α′′ precipitation and fragmentation or globularization of elongated α grains. The aging process at 550◦C leads to an increase in tensile strength and a decrease in ductility. © 2022 by the authors. Licensee MDPI, Basel, Switzerland. | MDPI | 19961944 | |

The OFDM system has many advantages such as high spectral efficiency, robustness to channel fading, and immunity to impulse interference. However, it has a main drawback, which is the Peak to Average Power Ratio (PAPR). Selecting Mapping (SLM) and Partial Transmit Sequences (PTS) are the two essential techniques for reducing the PAPR; however, they need to send side information to indicate how the transmitter generates signals. In this paper, Particle Swarm Optimization (PSO)-based dummy sub-carriers are inserted with the data to reduce PAPR without transmitting side information. The incorporation of PSO-based Dummy Sub-carriers Insertion (DSI) method on this system is performed by measuring the PAPR at the IFFT output (Inverse Fast Fourier Transform) after adding 6 adaptive sub-carrier sequences to the input data of IFFT. The PSO-based dummy algorithm decides to send the data once the PAPR of this data sequence and dummy sub-carrier is under a specific threshold. Using MATLAB as a mathematical simulation tool, simulation results are presented for a standard OFDM network model. The network model has been simulated in an Additive White Gaussian Noise (AWGN) channel environment to investigate PAPR and Bit-Error Rate (BER) performance. The simulation results show that the dummy sequence based on PSO reduces PAPR down to 4 dB compared to a conventional OFDM system and down to 3 dB compared with the clipping technique for the same BER performance. © 2021 The Korean Institute of Communications and Information Sciences (KICS) | Korean Institute of Communication Sciences | 24059595 | |

It took a realistic wave function that is not covered with these considerations together elsewhere. The results show that by applying very high tunneling, the in- and out-scattering processes of the double QD are slowed by state filling, while moderate tunneling was accelerated. The incoherent pumping makes the processes faster, except at high WL occupation. Bandgap engineering, which is of central importance for material researchers, experiences two possibilities: the wide-bandgap QDs have fast QD processes, while deep QDs are associated with slow processes. The high momenta correspond with fast QD processes. © 2022, The Minerals, Metals & Materials Society. | Springer | 3615235 | |

To our knowledge, the adopted approach is the first technique to be proposed and applied in the water demand prediction. Compared to traditional methods, the developed methodology is superior in terms of predictive accuracy and runtime. Water consumption coupled with weather variables of the Melbourne City, from 2006 to 2015, were obtained from the South East Water retail company. The results showed that using data pre-processing techniques can significantly improve the quality of data and to select the best model input scenario. Additionally, it was noticed that the particle swarm optimisation algorithm accurately predicts the constants of the suggested model. Furthermore, the results confirmed that the proposed methodology accurately estimated the monthly data of municipal water demand based on a range of statistical criteria. © 2020 The Authors | King Saud University | 10183639 | |

Methods: A total of 120 healthy adult mice (weighing about 25±5 g) were included in this study. Sixty mice out of the total were used to determine LD50, 30 mice to determine the anti-inflammatory test, and the remaining (30 mice) were used for an analgesic test. The hot plate was used to determine the analgesic effect, while the anti-inflammatory effect was determined by the ability of the compound to minimize the inflammation and edema caused by the injection of car-rageenan. Results: Lawsone was isolated from Lawsonia inermis. A Stuart SMP10 digital melting point apparatus was used for measuring all melting points. Infrared spectrometer FT-IR 400D was used for measuring/recording IR spectra (KBr) which the frequency of absorption was represented as cm−1. For 1H-NMR spectrum recording, a Bruk-spectrophotometer of 400 MHz was used with internal TMS standard, with deuterated Ś 2.51 ppm for acetone-d6, re-mained solvent signals as well as 13C.NMR was used. TLC was utilized as adsorbent, UV light, or iodine-completed visualization to verify compounds' purities. The LD50 of the oral lawsone was 96 mg/kg, and the highest dosage that did not kill any of the experimental animals was 80 mg/kg, which was used to investigate lawsone's analgesic and anti-inflammatory effects. Lawsone and aspirin possessed an analgesic effect compared to the control group (p<0.0001 and p<0.001, respective-ly); however, lawsone induced a potent analgesic effect compared to aspirin (p<0.1). In contrast, Lawsone and aspirin exerted an anti-inflammatory effect (p<0.05) compared to the control group and were equipotent in carrageenan-induced hind paw edema. Conclusion: It is concluded that lawsone possesses analgesic and anti-inflammatory effects, which endorse the practi-cal medical importance of Lawsonia inermis. The latter is widely used traditionally for these purposes own to its cost-effectiveness and safety; however, further studies are required to determine the systemic safety of lawsone. © The Author(s) 2022. | Technology Center | 25194844 | |

There is a strong demand to recognize the seizures in more automatic manner. Developing an expert seizure detection system with an acceptable performance level can partly fill this research gap. This paper proposes a new framework for the automated detection of neonatal seizures based on the Morse Wavelet approach that is coupled with a local binary pattern algorithm, and a graph-based community detection algorithm. An ensemble classifier method is designed to detect neonatal seizures prevalent in EEG signals. Our findings show that only 59 of the texture features can exhibit the abnormal increase in an EEG amplitude and the spikes notable during a seizure. The present results demonstrate that the proposed seizure detection model is more accurate for the detection of seizures compared with some of the traditional approaches. © 2022 Elsevier Ltd | Elsevier B.V. | 2632241 | |

Alcoholics are more vulnerable to health issues, such as immune disorders, high blood pressure, brain anomalies, and heart problems. These health issues are also a significant cost to national health systems. To help health professionals to diagnose the disease with a high rate of accuracy, there is an urgent need to create accurate and automated diagnosis systems capable of classifying human bio-signals. In this study, an automatic system, denoted as (CT-BS- Cov-Eig based FOA-F-SVM), has been proposed to detect the prevalence and health effects of alcoholism from multichannel electroencephalogram (EEG) signals. The EEG signals are segmented into small intervals, with each segment passed to a clustering technique-based bootstrap (CT-BS) for the selection of modeling samples. A covariance matrix method with its eigenvalues (Cov-Eig) is integrated with the CT-BS system and applied for useful feature extraction related to alcoholism. To select the most relevant features, a nonparametric approach is adopted, and to classify the extracted features, a radius-margin-based support vector machine (F-SVM) with a fruit fly optimization algorithm (FOA), (i.e., FOA-F-SVM) is utilized. To assess the performance of the proposed CT-BS model, different types of evaluation methods are employed, and the proposed model is compared with the state-of-the-art models to benchmark the overall effectiveness of the newly designed system for EEG signals. The results in this study show that the proposed CT-BS model is more effective than the other commonly used methods and yields a high accuracy rate of 99%. In comparison with the state-of-the-art algorithms tested on identical databases describing the capability of the newly proposed FOA-F-SVM method, the study ascertains the proposed model as a promising medical diagnostic tool with potential implementation in automated alcoholism detection systems used by clinicians and other health practitioners. The proposed model, adopted as an expert system where EEG data could be classified through advanced pattern recognition techniques, can assist neurologists and other health professionals in the accurate and reliable diagnosis and treatment decisions related to alcoholism.

Five different kinetic models were used (first-order kinetic, cone, modified Gompertz, logistic, and transference models) to find the kinetic parameters for the co-digestion of ML and PM. The methane production results proved that the addition of PM highly improved the ML methane production; the highest biodegradability and methane yield of 86% and 465 mL CH4 g−1 VS, respectively, were obtained at ML:PM ratio of 1:3, which were 160%, 26.5%, 19%, and 72% and 196%, 37%, 24%, and 66% higher than those of 1:0, 3:1, 1:1, and 0:1 mixing ratios, respectively. The cone model (as proved by low root mean square error (RMSE) and Akaike’s Information Criterion (AIC)) showed a better fit to the experimental data. The results of the present work showed the synergistic effect of co-digestion to enhance anaerobic degradation of mango leaves and pig manure for biogas production, providing a practical basis for an energy-efficient strategy for bio-waste management. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature. | Springer Science and Business Media Deutschland GmbH | 21906815 | |

Let G=(V,E) be a finite, simple and undirected graph without isolated vertex, a subset D of V is a triple effect dominating set if every vertex v ∈ D dominates three vertices from V -D. The triple effect domination number, denotes γte(G) is the minimum cardinality over all triple effect dominating sets in G.

Usually, poultry houses are located in a remote area where there is no electricity, and where there is electricity, it is expensive, so resorting to these solutions is considered important solutions to save electrical energy and provide free cooling. This research studies a numerical the influence of some plan parameters (the pipe diameter, inside condition, pipe lengths, and exit condition) and the capability of using solar energy to decrease the electricity consumption for air conditioning of poultry houses and on the overall performance of the EAHEs.. The diameter of the EAHE pipe 4 in (0.1016 m), pipe lengths of (355, 370m, 385m, 395m and 410m) and are studied solar radiation intensity 1000 W/m2 with constant flow rate. This numerical study has been done for winter and summer seasons in Nasiriyah city of southern Iraq. The simulation results showed that the combination of solar energy and EAHE can be used for cooling and heating the poultry houses and the heat released by heat exchanger reduced with increasing the outlet temperature of air and increased with increasing length of pipe of EAHE. While the overall performance factor of EAHEs declined with increase of length of pipe, also the solar energy increased with increasing length of pipe of EAHE. © 2022 Author(s). | American Institute of Physics Inc. | 0094243X | |

As a result, the nerves loss their ability to send and receive messages. The electrical models of the nerve fiber have been studied extensively for the normal case. However, there are no many studies on modeling a nerve fiber infected by MS disease. In this study, we aim to quantify the distortion in the neural signal transmitted through the infected fiber. We derived a mathematical expression to the signal propagated through the disordered part. The derived expression revealed that the distortion is caused by a change in the input impedance at the disease location. Furthermore, we compute the mean square error between the samples of the signal transmitted through the infected fiber and those of the signal propagated through the normal fiber. Our results show that the signal is totally distorted when the disease covers only one internode of the fiber © 2022 Author(s). | American Institute of Physics Inc. | 0094243X | |

Properties of the new breed of material are changing perpetually across the thickness direction and obeys the power-law distribution. In the current model a mixture of materials is used, i.e the inner and outer surface of the pipe is composed of ceramic materials, whereas the surface in the middle is composed of aluminium material. The vibration equations of FG pipe are obtained by using Hamilton's principle based on the Euler-Bernoulli model with (Clamped-Free) boundary conditions. The vibration frequencies of FG pipe was found by using an effective numerical method (differential quadrature (GDQ). Three models of FGM pipe are used in this paper (the proposed model and two models were taken from literature). The effects of gradient index and flow velocity on frequencies of FG fluid conveying pipes are investigated. The proposed model gave better outcomes compared with the other existing models, where the increase in natural frequencies was 17%, compared with the first model, and 21.69% compared with the second model, with the gradient index=3, moreover, this percentage of vibration frequency increases alongside with the increase of the gradient index. © 2022 Author(s). | American Institute of Physics Inc. | 0094243X | |

This architectural expansion places a great deal of responsibility on the engineer to anticipate the appropriate load for the constructor. Unfortunately, calculations of the pile's bearing capacity are not accessible. It has always been a source of concern for geotechnical engineers, as the structure's safety depends on the pile's bearing capacity and gives it a safe value. These research tests are previously known pile load test data from several locations in Nasiriyah to determine the ultimate load-carrying capacity using various interpreting methodologies. A database that was used to test the pile load for three different areas in Nasiriyah, southern Iraq: The Main Drain River Bridge Project, the Al-Eskan Interchange Project, and the Al-Hawra Hospital, as determined by analytical methods, as well as evaluating the final loading values resulting from the methods used, by ASTM D-1143, American and British Standard Code of Practice BS 800. The final capacity for the pile bearing is estimated using these approaches, which are depicted in the form of a graph-based on field data. Chin-Kondner and Brinch Hansen algorithms anticipate the highest failure load for all piles based on the comparison. On average, Chin-Kondner's ultimate load is 22% higher than Hansen's maximum load for the 22 pile load tests.

It became controversial and debated how to estimate the characteristic value of soils to obtain a reliable geotechnical design with low cost and less effort. Usually, foundations are not built on the same site as the screening; investigations are carried out to excavate a little at essential sites. In this paper (423), test wells were collected in the study area to be obtained and tabulated in Excel. The kriging statistics is applied using a python script to predict the values of geotechnical site properties and reliability of the method in estimating spatially varying soil properties values based on measurement data and prior knowledge. The program implements probabilistic kriging statistics and predicts the desired value by entering the coordinates of the locations whose properties you want to know and based on the previously prepared Excel file of known points, coordinates, and property values. The program will be used in two soil sites in the city of Nasiriyah to predict its properties. These points were selected from the examination of soil investigation reports to determine the reliability and accuracy of the program in predicting values. To get more reliable probability values using the kriging method and python scripts. A huge database of prepared and analyzed engineering soil properties has been created based on field investigation reports for projects in Nasiriyah. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17551307 | |

Although the use of passwords provides an acceptable control and authentication, it has shown much weakness in terms of speed and integrity, which make biometrics the ideal authentication solution. As a result, electrocardiogram (ECG) signals have received a great attention in most authentication systems due to the individualized nature of the ECG signals that make them difficult to counterfeit and ubiquitous. In this paper, we propose a new model for ECG verification using multi-domain features coupled with a least square support vector machine (LS-SVM). Two types of features are investigated to find the best set of features to individual from ECG signals. Time domain and frequency domain features based on optimized Triple Band filter bank are extracted from ECG signals. The extracted features are investigated to figure out the best relevant features and remove the redundant ones. The selected features are fed to three classifiers, including Least Square Support Vector Machine (LS-SVM), K-means, and K-nearest. The obtained results have shown that our ECG biometric authentication system outperforms existing methods. The proposed model obtained an average of accuracy of 88%, 95% with time and frequency features, respectively, while it recorded 99% when a combination of time and frequency features are used to classify ECG signals. A public dataset is used to assess the proposed model. © 2022 Informa UK Limited, trading as Taylor & Francis Group. | Taylor and Francis Ltd. | 10255842 | |

The action potential detection approach is essential to evaluation the times at which spike activated. Recordings from the multi-electrode cuff typically have a minimum signal to noise ratio less than 10. In this paper, an LSM adaptive filter is designed and implemented employing Matlab and Xilinx Spartan 3E-100 (xc3s100e) software and hardware tool. The proposal filter shows a significant enhancement in the noise rejection and power-consuming and hardware size reduction. Furthermore, the outcomes illustrate that the LSM adaptive filter efficiently works in online neural recording with essential upgrading in the signal to noise ratio (SNR). Consequently, this improvement could lead to more spike detection accuracy. It can make the sensitivity of > 80% with a false positive rate of less than 6 Hz in recordings with SNR = 5, and it performs better than an optimal threshold detector using bandpass filter in recordings with SNR > 3. The present filter configuration offers a notable reduction of 10% in power consumption and 25% of the hardware required contrasting with the conventional approach of digital filter algorithm. Therefore, this study could suggest a crucial improvement to boost the neural recording to be applied as a control signal for the prosthetics devices. © 2021 | Elsevier Ltd | 22147853 | |

Manual detection of PCOS is a challenging task for specialists, however, detection of PCOS as quick and accurate could save the lives of millions of women over the world. Current studies use high dimension features which leads to a low estimation accuracy, and high execution time. However, in this article, we develop a new intelligence system to classify PCOS based on k-means coupled with a LS-SVM (K-M-SVM) using a lower number of features. The original dataset is preprocessed and then k-means is applied to select the most powerful features based on Euclidean distance to classify PCOS. It was found that the k-means cluster had a high potential in selection the most influential features and eliminating the poor ones. As a result, a total of six features are chosen to represent PCOS data from the original features. The selected feature set are fed to the LS-SVM to classify them into healthy and no healthy segments. Our findings showed that the proposed model (K-M-SVM) outperformed the state of the art, and it gained an accuracy of 99%. © 2022 John Wiley & Sons, Ltd. | John Wiley and Sons Ltd | 15320626 | |

Numerous researches have been conducted on the manifestations of a skin disease related to COVID-19, i.e., rashes or Pityriasis rosea (PR), vascular markings, and pimple-like lesions. AIM: This study aims to find out if the Coronavirus can affect the PR development, which also can be considered as a trigger and symptom for other types of infections. MATERIAL AND METHODS: This study is a case series describing the dermatological findings related to COVID-19 in the Thi-Qar Governorate. Samples were taken from inpatients, outpatients, and from the emergency unit of Al Hussein Teaching Hospital, and inwards of Al-Shefaa' Isolation Hospital. The study has been done over a 4 month period (June-September, 2020.). RESULTS: Around 19 patients, 10 females (52.6%) and 9 males (47.4%), who were infected with Coronavirus and were suffering from PR, are included in this study. The distribution of patients according to the incidence of PR in typical and anomalous manners were 77.9% and 21.1% respectively. The highest percentage of the incidence of PR was in moderate COVID-19 (84.2%), while it was around 15.8% in mild COVID-19. There was no significant statistical difference in the mean age distribution according to gender, while there was a significant statistical difference according to PR and COVID-19 class. More studies are needed to evaluate whether or not these lesions are associated with the virus. CONCLUSION: The PR was one of the dermatological finding of COVID-19 that did not have a clear role in the distribution of the disease according to the background of the patients, and also the severity of COVID-19. It can be triggered by COVID-19 and be completely cured with the clearance of the disease. RECOMMENDATION: An accurate robust cutaneous documentation related to COVID-19 is required to improve the knowledge of the disease as well as its epidemiology. | NLM (Medline) | 25618741 | |

The coating by (In) in absence of oxygen enhances the stability of the corrosion product as MgO through reducing the corrosion current density. While the presence of oxygen during coating accelerates the corrosion rate due to increasing the cathodic polarization through the reduction of oxygen and then increasing the dissolution of Mg from the substrate. The coating by (In) gave protection efficiency reach to (21.008%). While the presence of oxygen during DC sputtering promotes the cathodic area on grains as (In2O3) leading to localize the corrosion around the AlMn phases at the grain boundaries.

The ratios of replacement natural coarse aggregate by RCA were (0, 35, 55, and 75%) and the volume fraction of the steel fiber used in this study was 1.2%. Two strengthening methods were used, namely, externally bonded reinforcement (EBR) and externally bonded reinforcement on groove (EBROG). 16 square slabs were cast with overall dimensions of 800 mm by 800 mm by 80 mm thickness. The slabs were designed to fail in punching shear only. All the slabs were simply supported on four edges and tested for punching via a vertical load applied through the square central column. The test results showed that the mechanical properties, ultimate loads, and first crack loads decreased with increasing proportion of RCA replacement, while the incorporation of steel fibers improved the compressive strength and ultimate loads by the ranges of 12%–17% and 16%–25%, respectively. Strengthened slabs lead to considerable improvements in the punching behavior of slabs, with an increase in punching load ranging from 22–30% compared to unstrengthened slabs when using the EBR technique, while the increase in the punching loads ranged between 40 and 55% when using EBROG strengthening technique. However, using half amount of CFRP with the EBROG method led to an increase in punching shear of 20–28%. This research indicates the particular improvement offered by the EBROG with regard to the punching shear capacity of fibrous recycled coarse aggregate concrete (RCAC) slabs compared to the EBR method. In addition, the mode of failure of reinforced concrete (RC) slabs changed from one of debonding failure to concrete cover separation when using the EBROG method. © The Author(s) 2022. | SAGE Publications Inc. | 13694332 | |

The parameter values of the coupling strength (η) and delay time (τ) (mirrors respond as fast and slow-response photorefractive mirrors) are modified to examine the sensitivity of routes to chaos with variation in the phase-conjugate mirrors. Both routes are found to be highly sensitive to the phase conjugate coupling effect. Instability and homoclinic chaotic can be observed in such a system. © 2022, The Author(s), under exclusive licence to The Optical Society of India. | Springer | 9728821 | |

The first one is traditional extraction which can be called liquid-liquid extraction (LLE) or solvent extraction, while the second is modern extraction, namely cloud point extraction (CPE). 3-Chloro-2,4-pentanedione was used as a complexing agent that is one of β-diketone that have an interesting in extracting copper ions. The current study showed that cloud point extraction (E%=92, D=11.594, LogD= 1.064233296) is more efficient than its counterpart (E%=80, D=4.089, LogD= 0.611). The cloud point extraction was studied using Triton X-100 as a non-ionic surfactant and ethyl acetate as a solvent. Also, complex CuA-Cl was prepared and characterized by elemental analysis and mass and UV-visible spectrometries. © 2022 Sami Publishing Company.

The Border Gateway Protocol (BGP) exchanges routing information between autonomous domains. Anomalies in BGP are exceptional (misconfiguration, outage, and attacks). When they happen, the consequences can be widely hurtful. Anomaly detection in the internet routing section does not follow the normal behavior as an element. It is more important than anything else to detect internet routing anomalies using the BGP update messages quickly and accurately. This paper will propose a Short-Term Long Memory-based Autoencoders network (LSTM-AE) method for internet routing anomaly detection and trains itself to repeat clean datasets effectively. These memory units are a type of artificial Recurrent Neural Networks (RNN) architecture used in deep learning, are convenient for historical study time series modeling and anomaly detection using LSTM memory units instead of ordinary neurons to build the coder.

This paper presents the design and manufacture technique of a tact hand, an anthropomorphic, open-source (O-S), Myoelectric Prosthetic Hand (MPH) for persons with transradial amputations in emerging state. The design process is based on balancing workability, cost, efficiency, durability, and effectiveness, and then manufacturing using 3D printing technology (3D-P). The findings showed that using lighter and hollow materials instead of rigid injection molded plastic materials reduced fatigue and pain caused by mass distributing to smoother tissues. But create the sensitivity hand system process, predict the sensitivity hand using qualitative and quantifiable events of enactment, and present samples of the usage of this hand to grab domestic things. The validation and findings were determined by comparing them to related studies, such as section four, where the functional usefulness of utilizing the hand to demonstrate a range of household items was discussed. Items like the water bottle and bottle cap, and the use of a 3-jaw chuck, key grip, and tool grip, were all simply understood by the tip. We combine electromyographic pattern recognition for motor control, contact reflexes, and sensory substitution to deliver input to the user. When compared to standard myoelectric prostheses that lack these features, the quality of rotation and other motions has also improved, and using contact reflexes and sensory substitution progresses grasping of delicate objects like an eggshell and a cup of water both with and without visual feedback. It can be shown that average intensity features (AIH) performed better than other feature sets (ACC ${AIH}=0.952954668\%, {PAIH}=0.966836735\%,\ {SAIH}=0.979323844\%$).

The first part describes the synthesis of a new series of organotellurium compounds containing azomethine groups. Reaction of (E)-(4-((1,7,7-trimethyl bicyclo[2.2.1]heptan-2-ylidene)amino)phenyl)mercury(II)chloride and (E)-(5-methyl-2-((1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)amino)phenyl) mercury(II)chloride with tellurium tetrabromide in 2:1 mole ratio yielded the tellurated Schiff bases Ar2TeBr2 (where Ar = 1-(C9H16C=N)C=N)C6H4 and 1-(C9H16C=N)C=N)-4-CH3C6H3) respectively. Reduction of organyl tellurium dibromide Ar2TeBr2 by hydrazine hydrate obtained the corresponding tellurides (i.e., Ar2Te) in good yields. Characterization of the prepared compounds was carried out using infrared spectrum (FT-IR), proton nuclear magnetic resonance spectrum (1H-NMR), and elemental analysis (CHN). The molecular structure of the organotellurium compounds was investigated using the density functional theory with hybrid functional (B3LYP), and the basis set 6-31G Geometrical structure, HOMO surfaces, LUMO surfaces, and energy gap have been produced throughout the geometry optimization. The molecular geometry and contours for the organotellurium compounds were investigated throughout the geometrical optimization. The donor and acceptor properties have been studied by comparing organotellurium compounds' highest occupied molecular orbital energies (HOMO). The present study aims to prepare organotellurium compounds derived from aniline, p-toluidine, and camphor and their derivatives using tellurated Schiff bases. © 2022, Gadjah Mada University.

This paper studies the engineering properties of a model of Nasiriyah soil. It aims to calculate the distinctive value of Nasiriyah soil and describe the different identification methods for laboratory tests. Knowledge of the properties of engineering parameters is essential for accurate design, measurement methods, and geotechnical investigation, and the Eurocode 7 approach of the soil is essential for geotechnical design. Therefore data were collected, and the characteristic values were determined using statistical methods. Three project sites in Nasiriyah city were studied to determine the correlation of soil strength parameters and calculate the characteristic value based on Eurocode 7. The study results showed that the Marquez method and Schneider's equations give characteristic values with a 95% reliable and economical design within the measured data range, taking into account the average, coefficient of variation of the site, and the number of measured data. It is found that the most appropriate characteristic values of the soil of the studied sites are less than the mean by half a standard deviation. © 2022 | Elsevier Ltd | 22147853 | |

Uropathogenic Escherichia coli (UPEC) strains are the most frequent uropathies linked to the development of UTIs. This work aims to introduce bioactive natural products via virtual screening of small molecules from a public database to prevent biofilm formation by inhibiting FimH, a type 1 fimbriae that plays a crucial role in UPEC pathogenicity. A total of 30926 small molecules from the NPASS database were subjected to screening via molecular docking. Followed by performing in silico ADME studies, seven molecules showed promising docking results ranging from −6.8 to −8.7 kcal/mol. As a result of the docking score findings, 100 ns Molecular dynamics (MD) simulations were performed. Based on MM-PBSA analysis, NPC313334 ligand showed high binding affinity −42 and stability with the binding pocket of FimH protein during molecular dynamic simulations. DFT calculations were also performed on the ligands to calculate the HOMO-LUMO energies of the compounds in order to an idea about their structure and reactivity. This research suggests that NPC313334 may be a possible antibacterial drug candidate that targets FimH to reduce the number of UPEC-related urinary tract infections. Communicated by Ramaswamy H.

Other emulsions, such as those produced of crude oil droplets suspended in brine or water (O/W), are uncommon. When crude oil is removed from a reservoir, it is contaminated with sediments and water, among other impurities. Natural emulsifiers include resins, asphaltenes, waxes, crude particles, and carboxylic acids. At the water-oil interface, some of these components may clump together, generating a stable film surrounding the droplets, by preventing water droplets from clumping, this film aids in the formation of a stable w/o emulsion. Water and crude oil production could raise a number of concerns. This could include the cost of pumping or transporting water via tanker or pipeline, as well as manufacturing facility corrosion. Chemical demulsification is the process of destabilizing the shielding interfacial layers with chemicals, resulting in a quicker emulsion breakdown rate. As a cost-effective and effective method of dewatering crude oil emulsions, chemical additives are frequently used. © 2022 Elsevier Ltd. All rights reserved. | Elsevier Ltd | 22147853 | |

The optical character recognition (OCR) technique presents a simple tool to combine text recognition functionality to many industrial and educational applications. Best OCR results can be acquired when the background of the text image is uniform and appears as a document picture. In contrast, the challenges to recognizing accurate texts occur when the image has a non-uniform background that require further preprocessing to obtain acceptable OCR result. This work discusses three scenarios. Initially, this work will test the OCR on a normal business card as an image with a uniform background. Next, discusses the text recognition of a keypad image including digits with a non-uniform background. Here, there are two preprocessing algorithms used to enhance the OCR function to overcome the negative effect of the non-uniform background of images and to detect text with high accuracy. Finally, the developed OCR method is tested on different scanned bills and discusses the variation of the obtained results. The two algorithms are the morphological reconstruction to eliminate artifacts and create cleaner images to be further processed by OCR and the Region of Interest ROI-based OCR to spot explicit regions in a tested image. Verification for the effectiveness of the Morphological-based OCR over the ROI-based method has been conducted on a dataset of scanned electricity bills images with an accuracy of 98.2 % for Morphological-based while it is only about 89.3 % for ROI-based OCR © 2022, Authors.

Different livestock plays an essential role in global milk production. This study was designed to evaluate different chemical and physical components of milk in four groups of livestock, including cows, buffalos, sheep, and goats. To this end, 200 raw milk samples were collected from cows, buffalos, sheep, and goats (n=50) across Dhi-Qar Governorate, Iraq, for a period of one year (from 01.10.2018 to 01.06.2019). The findings showed sheep and buffalos milk samples had a significantly higher percentage of total solids (TS%), compared to cows and goats milk samples (P0.05). However, there were no significant differences in the TS% between sheep and buffalos milk samples. Furthermore, the mean TS% values in cows, buffalos, sheep, and goats milk samples were determined at 11.14%, 12.87%, 13.26%, and 11.33%, respectively. As for fat percentage (F%), buffalos milk samples had significantly higher F% (4.80%), compared to milk samples of cows, sheep, and goats (P0.05). Additionally, sheep s milk samples had significantly higher F% (P0.05) than cows and goats milk samples determined at 2.78%, 4.20%, and 2.98%, respectively. The findings showed the percentage of solids not fat (SNF%) was significantly higher in sheep s milk (8.97%), compared to milk samples of cows, buffalos, and goats (P0.05). Additionally, it was found that the SNF% was significantly higher (P0.05) in Buffalos milk samples, compared to cows and goats milk samples determined at 8.36%, 8.60%, and 8.35%, respectively. Moreover, the results revealed that the percentage of milk protein content in sheep s milk was significantly higher than the cows, buffalos, and goats milk (P0.05). Recorded data also showed no significant differences in the percentage of milk lactose among cows, buffalos, sheep, and goats milk samples (P0.05). Furthermore, the findings illustrated that the percentage of milk ash (Ash%) in sheep s milk samples was significantly higher than the cows, buffalos, as well as goats milk samples (P0.05), and no significant differences were observed among cows, buffalos, and goats milk samples in the Ash% (P0.05).

Osteoporosis (OP) is a worldwide ailment; we aim to establish new biomarkers in diagnosis by determining the levels of serum osteocalcin and osteopontin along with bone mineral density (BMD) and lumbar T-score, in postmenopausal women with type 2 diabetes mellitus (T2DM) with or without OP. Methods. This observational study included 160 postmenopausal women who were an attendee at outpatient clinics in Al-Hussein Hospital, Thi-Qar province; subdivided into 3 groups based on their T-score testing: Group I (n = 40) comprised postmenopausal women without T2DM as controls, Group II (n = 60) comprised postmenopausal women with T2DM but without OP, and Group III (n = 60) comprised postmenopausal women with T2DM with OP. The dual-energy X-ray absorptiometry was used to measure the BMD (total body, lumbar spine, and femoral) and T-score for lumbar spine and femoral. Glycosylated hemoglobin (HbA1c), fasting blood glucose (FBG), osteocalcin, and osteopontin levels were assessed in all three groups. Results. Compared with controls, Group III demonstrated significantly lower BMD (total body, lumbar spine, and femoral), T-score for lumbar spine and femoral, serum osteocalcin, and osteopontin levels than Group II and Group I (P<0.001). FBG and HbA1c levels were significantly higher in Group III than in Groups I and II (P<0.001). A negative correlation was proved between HbA1c levels with BMD, osteocalcin levels, and osteopontin levels in the three groups. Conclusions. Iraqi postmenopausal women with T2DM had a significantly lower bone mineral density, serum osteocalcin, and osteopontin levels. These results may serve as adjuvants in screening for OP, particularly among diabetic patients. © 2022 Ali B. Roomi et al. | Hindawi Limited | 20908059 | |

Box 55431, Ramadi, Iraq | This study aims at investigating the extent to which the aesthetic effect (AE) in Gibran's The Prophet has been maintained among Arab recipients in four translations of this masterpiece, namely Okasha (2000), Nuaimy (2013), Al-ābid (2017), and Antonius (2017). To this end, the source text (ST) AE laden segments and their target text (TT) counterparts are compared in terms of lexical selection, sentence structure, and metaphors employed. Data of the study comprised typical illustrative examples randomly selected for analysis according to Yan Fu's (2012, cited in Zhang 2013) triple translation criteria of faithfulness, expressiveness, and elegance in combination with Nida's (1964) functional equivalence. Findings of the study revealed that the selected translations exhibit different levels of adequacy in terms of expressing the AE in the TT. Specifically, Okasha's translation seems more creatively adequate in producing in the TT the approximate AE of the ST, whereas the other translations are sometimes less adequate or even inadequate in this respect. © Penerbit Universiti Sains Malaysia, 2022.

The generation of solar fuel-based water splitting and CO2 photoreduction is excellent for generating alternative resources and reducing global warming. Developing an inexpensive photocatalyst can effectively split water into hydrogen (H2), oxygen (O2) sources, and carbon dioxide (CO2) into fuel sources, which is a crucial problem in photocatalysis. The metal-free g-C3N4 photocatalyst has a high solar fuel generation potential. This review covers the most recent advancements in g-C3N4 preparation, including innovative design concepts and new synthesis methods, and novel ideas for expanding the light absorption of pure g-C3N4 for photocatalytic application. Similarly, the main issue concerning research and prospects in photocatalysts based g-C3N4 was also discussed. The current dissertation provides an overview of comprehensive understanding of the exploitation of the extraordinary systemic and characteristics, as well as the fabrication processes and uses of g-C3N4. © 2022 The Chemical Society of Japan & Wiley-VCH GmbH | John Wiley and Sons Inc | 15278999 | |

For any non-negative integers x and y, a set D ⊆V is a "pitchfork dominating set pds", when every vertex in D, dominates at most y and at least x vertices of V -D. A subset D-1 of V -D is an inverse pds if it is a pitchfork set. The pitchfork domination number of G, γpf (G), is the number of elements of a smallest pds. The "inverse pitchfork domination number" of G, -1 γpf (G), is the number of elements of a smallest inverse pds. In this paper, some modified pitchfork dominations and its inverse dominations are introduced when x = 1 and y = 2. Several bounds and properties are given and proved. Then, these modified dominations are applied on some standard graphs such as: Path, cycle, wheel, complete, complete bipartite graph and their complements. © 2022 Boletim da Sociedade Paranaense de Matematica.

Higher levels of flogosis mediators such as TNF, C-reactive protein (CRP), IL-1, IL-6, leptin, and resistin, as well as increased levels of TNF, C-reactive protein (CRP), IL-1, IL-6, leptin, and resistin, define diabetes. The goal of this study is to evaluate the levels of D-dimer, total serum bilirubin (TSB), glutamic-oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and CRP in diabetic patients with COVID-19 infection to COVID-19 patients without diabetes. Blood samples were collected from individuals with diabetes who had COVID-19 and non-diabetic COVID patients as control. Moreover, D-dimer and CRP were evaluated by using Min Vidus and Latx, respectively, whereas AccEnT 200 system was used to measure the serum level of TSB, GPT, and GOT in the hematology lab. Also demonstrated that the average serum concentration of D-dimer, GOT and CRP was high in diabetic COVID-19-infected patients (980.66 ng/mL, 67.71 U/L, and 27.06 mg/L, respectively) compared with non-diabetic COVID-19-infected patients (791.17 ng/mL, 54.023 U/L and 20.11 mg/L, respectively) (p < 0.05), while the situation was inverse for the average concentration of TSB and GTP when their average concentrations were low in diabetic COVID-19-infected patients (12.89 Mmol/L and 59.79 U/L, respectively) (p > 0.05). Moreover, the cut-off values for serum D-dimer, TSB, GPT, GOT, and CRP of COVID-19-infected diabetic patients were ≥ 6500 ng/mL, ≥ 350 Mmol/L, ≥ 133 U/L mg/L, ≥ 150 U/L, and ≥ 15.22 mg/L, respectively, represented a perfect test for predicting COVID-19-infected diabetic patients with 100% sensitivity and specificity. In conclusion, serum D-dimer, TSB, GPT, GOT and CRP increased in diabetic COVID-19-infected patients compared to non-diabetic COVID-19 patients and the D-dimer concentration also increases. TSB and CRP were more pronounced among diabetic patients with corona, while liver enzyme concentrations were decreased. © 2021, King Abdulaziz City for Science and Technology. | Springer Science and Business Media Deutschland GmbH | 21905509 | |

Monthly air temperature and pan evaporation are used to build the predictive models. These models are used for evaluating the evaporation prediction for the Kiashahr meteorological station located in the north of Iran and Ranichauri station positioned in Uttarakhand State of India. Findings indicated that the deep learning model was found best at Kiashahr station for testing datasets MAE (0.5691, mm/month), RMSE (0.7111, mm/month), NSE (0.7496), and IOA (0.9413). It can be concluded that in the semi-arid climate of Iran both of the used methods had the good capability in modeling of monthly E pan. However, DL predicted monthly E pan better than GBM. Moreover, the highest accuracy of the deep learning model was also observed for the Ranichauri station in terms of MAE = 0.3693 mm/month, RMSE = 0.4357 mm/month, NSE = 0.8344, & IOA = 0.9507 in testing stage. Overall, results expose the superior performance of DL-based models for both study stations and can also be utilized for various other environmental modeling. © 2022 The Author(s).

The present study aimed to explore the bioindustry, mold screening protocol, and characterization of zinc oxide nanoparticles (ZnONPs) using a diverse filamentous Green mold (FiGM) isolated from spoiled citrus fruits. Eight filamentous Penicillium digitatum mold strains had been obtained and subjected to investigate the capability of ZnONPs biosynthesis by fungal extracellular free-cell filtrate. P. digitatum (P-digB3) obtained the peak of ZnONps (379 nm) detected by the UV-visible spectrophotometry and was found as a significantly optimum strain in the highest quantity (mean±SD: 0.0138±0.001 gm/100 ml) and the smallest average NPs size. The ZnONPs were characterized by UV-visible scanning spectrophotometry, Atomic Force Microscopy, X-RD, Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM).

However, the efficient extraction and effective selection of informative EEG features is crucial in assisting clinicians to diagnose epilepsy accurately. In this paper, a determinant of covariance matrix (Cov–Det) model is suggested for reducing EEG dimensionality. First, EEG signals are segmented into intervals using a sliding window technique. Then, Cov–Det is applied to each interval. To construct a features vector, a set of statistical features are extracted from each interval. To eliminate redundant features, the Kolmogorov–Smirnov (KST) and Mann–Whitney U (MWUT) tests are integrated, the extracted features ranked based on KST and MWUT metrics, and arithmetic operators are adopted to construe the most pertinent classified features for each pair in the EEG signal group. The selected features are then fed into the proposed AdaBoost Back-Propagation neural network (AB_BP_NN) to effectively classify EEG signals into seizure and free seizure segments. Finally, the AB_BP_NN is compared with several classical machine learning techniques; the results demonstrate that the proposed mode of AB_BP_NN provides insignificant false positive rates, simpler design, and robustness in classifying epileptic signals. Two datasets, the Bern–Barcelona and Bonn datasets, are used for performance evaluation. The proposed technique achieved an average accuracy of 100% and 98.86%, respectively, for the Bern–Barcelona and Bonn datasets, which is considered a noteworthy improvement compared to the current state-of-the-art methods. © 2021 by the authors.

In this regard, the current paper presents a roadmap to assess the temporal complementarity patterns between wind and solar resources for the first time in Iraq. A new approach based on re‐analyzed climate data, Landcover products, and geographical information system (GIS) is proposed. As such, renewable resource datasets are col-lected for 759 locations with a daily timescale over five years. Landcover classes are translated into wind shear coefficients (WSCs) to model wind velocity at turbine hub height. Then, the Pearson correlation coefficient (PCC) is applied to calculate the complementarity indices for each month of the year. Results of this investigation reveal that there are significant synergy patterns spanning more than six months in the southwestern regions and some eastern parts of Iraq. The highest com-plementarity is observed in March and December with a value of −0.70 and −0.63, respectively. De-spite this promising potential, no typical temporal complementarity has been discovered that would completely eliminate the fluctuations of clean power generation. However, the synergistic proper-ties yielded by this work could mitigate the reliance on storage systems, particularly as they cover important regions of the country. The proposed approach and tools can help improve the planning of renewable energy systems. © 2021 by the authors. Li-censee MDPI, Basel, Switzerland. | MDPI | 20711050 | |

The production, processing, transport and storage phases of chillies are prone to infection by Aspergillus Section Flavi and contamination with aflatoxins (AFs), especially aflatoxin B1 (AFB1) for which legislative limits exist in many countries. We have examined the effect of the interacting abiotic factors of water availability (water activity, aw; 0.995-0.850 aw) and temperature (15-37 °C) on (a) lag phases prior to growth, (b) growth, (c) AFB1 production and (d) contour maps of optimum and boundary conditions for colonisation and toxin production by three Aspergillus flavus strains on a 10% chilli-based medium. Additional studies with whole red chillies + A. flavus conidial inoculum on AFB1 contamination during storage for 10-20 days at 30 °C were also carried out. In vitro, the lag phases before growth were delayed by lower temperatures (15, 20 °C) and aw levels (0.928-0.901 aw). There was no statistical difference in growth between the three strains. Optimal growth was at 37 °C and 0.982 aw with no growth at 0.85 aw. Optimal temperature × aw conditions for AFB1 production were at 30 °C and 0.982 aw with no statistical difference in production between strains. No AFB1 was produced at 15-20 °C at 0.901 and 0.928 aw levels, respectively. In situ studies with A. flavus inoculated whole red chillies at 0.90 and 0.95 aw found that this species became the major component of the total fungal populations at 30 °C after 10-20 days storage. AFB1 contamination was above the European legislative limits (5 μg/kg) for spices at 0.90 aw after 20 days storage and at 0.95 aw after 10 and 20 days. This suggests that storage conditions of ≥0.90 aw, especially at ≥25-30 °C represents a significant risk of contamination with AFB1 at levels where rejection might occur, even after only 10-20 days storage. © 2021 Wageningen Academic Publishers. | Wageningen Academic Publishers | 18750710 | |

However, the evaporation of water from these ponds is a significant problem that must be overcome for them to be deployed successfully. Thus, two ponds were constructed in the city of Nasiriya, Iraq. The two ponds were cylindrical with a diameter of 1.4 m and a total depth of 1.4 m. The water body in the two ponds was constructed with layer depths of 0.5, 0.75 and 0.1 m for the lower convective zone (LCZ), non-convective zone (NCZ) and the upper convective zone (UCZ) respectively. One of the two ponds was covered with a thin liquid paraffin layer (0.5 cm) to eliminate evaporation from the surface of the UCZ. The behavior of the standard SGSP and that of the covered pond with evaporation suppressed can be straightforwardly compared. The experimental units were run for six months from 1st of February to 31st of July 2019. It was shown in the first instance that by covering the pond with a thin layer of paraffin, that evaporation could be suppressed. The results showed that for the conventional SGSP, the temperature of the LCZ reached a maximum of ca. 76◦C while in the covered pond the temperature of the LCZ was consistently lower than that in the uncovered pond by approximately 5–6◦C. The results also indicated that the temperature of the UCZ in the covered pond was higher than that in the uncovered pond by about 10◦C in the second half of the study period. However, it was noted that on rainy days the paraffin layer was swept away from the surface; and this could hinder the implementation of thin liquid cover in the large SGSP. © 2022, Tech Science Press.

Our design includes a metal film incorporated within the PCF structure. Compared to previously discussed sensing configurations, the metal surface does not come in direct contact with the sample being tested in our design. The metal film serves to provide absorption due to the excitation of surface plasmon-polaritons (SPP). This absorption is enhanced when a PCF-guided mode resonantly couples to the SPP, or in other words when phase matching between the mode and the SPP is satisfied. We consider a configuration where a hollow PCF core is filled with a liquid sample, while the metal surfaces are kept tens of microns away within the PCF cladding. Our sensor detects small changes in the sample's refractive index, over a broad wavelength range, by taking advantage of the refractive index sensitivity of the resonance/phase-matching condition. We model the sensor and characterize its performance by using the COMSOL environment based on the finite element method. We evaluate and compare three elements: gold, silver, and copper, in order to increase the absorption at particular wavelengths. We also vary the thickness of the metal layer and optimize it to enhance the sensitivity. The results show a performance that exceeds a minimal sensor resolution over an ultra-broad spectral range while maintaining a reasonable amplitude sensitivity. © 2021 Elsevier GmbH | Elsevier GmbH | 304026 | |

Up to date writing this paper, nobody has used this type of extracted lignin as PVC photo-stabilizer. Therefor this significant application was exhibited in this study by utilizing lignin as eco-friendly photo-stabilizer of PVC. Many approaches have been applied to test the efficiency of it as natural additive of PVC. Infrared spectra shows the growing of two specific bands during irradiation belong to carbonyl (C[dbnd]O) and alkene (C[dbnd]C) groups due to the photo-degradation. It was demonstrated that using lignin inhibits the formation of these two peaks substantially and stabilize the polymer. Various other experiments were done such as weight loss percentage, average molecular weight and surface study by AFM and SEM. All the results were in agreements and proved that lignin could be used as an excellent photo-stabilizer of PVC. Moreover it was demonstrated that increasing the concentration of lignin from 0.5% to 1% per polymer weight has increase the stability of PVC. It was also suggested the mechanism of stability hence lignin is highly aromatic and has a lot of phenolic hydroxyl groups which make it a very good UV-blocker and excellent free radical scavenger. © 2021 | KeAi Communications Co. | 25892991 | |

We demonstrated that all of the new suggested complexes have a lower energy gap than oxaliplatinum, and that they are also more energetic than oxaliplatin because of their high molecular polarizability. The indicated oxaliplatinum complexes (O1, O2, and O3) have a lower global hardness than oxaliplatinum, meaning that they are more soft complexes in this paper and therefore active complexes to interact with other molecules or species, according to the quantum chemical parameters calculations. The potential of a complex to interact with an enzyme increases as the EHOMO of the complex increases and the ELUMO of the complex decreases. © 2021 | Elsevier Ltd | 22147853 | |

In this respect, an innovative smart energy system based on hybrid solar-geothermal energies is proposed in this work, and transient performance assessment and techno-economic analysis are presented to evaluate its dynamic performance applying TRNSYS software. The proposed system is developed to provide power, heating, and cooling demands for a small urban community as the case study. The system consists of PVT panels, thermal energy storage tanks, a turbine, an absorption chiller, and a heat pump as the main components. Also, other subsidiary components like controllers and diverters are incorporated to guarantee the proposed system performance in a smart manner in various ambient conditions of the year. The results show that the system not only provides the annual electrical demand for the considered case study but also a considerable amount of excess power is produced, which can be sold to the power grid to compensate for some expenses of the system. The highest and the lowest exergy efficiency for the proposed system is attained in July and December with the values of 55.9% and 22.8%, respectively. Also, the highest and the lowest values of system unit product cost are obtained for January and July, respectively, as 8.38 and 32.77 $/GJ. © 2021 | Elsevier Ltd | 22106707 | |

This study aims to experimentally investigate the effectiveness of EBROG as compared to the conventional externally bonded reinforcement (EBR) method in strengthening reinforced concrete (RC) beams. Twelve RC beams have been tested under four point load bending. One of these beams has been designated as a reference beam, seven beams have been strengthened with carbon fiber reinforced polymer (CFRP) sheets, and four beams have been strengthened with CFRP laminates using EBROG or EBR methods. The effect of CFRP type, number of layers, as well as the type of strengthening methods on the flexural performance have been also investigated. The load, deflection, stiffness, and failure modes were recorded and discussed intensively. Overall, test results indicated that the flexural strength and stiffness of the strengthened specimens using EBR or EBROG methods increased compared to the control beam, where the increase in the load carrying capacity of beams strengthened using the EBR method ranged between 24.8 and 48.2% and by the EBROG method ranged between 31.7 and 76.7% of the control beam. The most interesting result obtained is that the failure mode of beams has been changed from debonding of CFRP material to rupture of CFRP in some samples strengthened by EBROG, which demonstrates the superior behavior of this strengthening technique as compared to the traditional strengthening using EBR. © The Author(s) 2021. | SAGE Publications Inc. | 13694332 | |

For ionic liquids, there are several advantages over conventionally using organic membrane solvents, including high thermal stability, negligible vapour pressure, low volatility, etc. Here in this study, we have analyzed the abilities of ionic liquids as pure solvents as well as their binary mixtures, to recover phenolic compounds from the industrial wastewater. The field of phenol extraction from wastewater using ionic liquids remains less exposed, and we presume that the work of this kind would open up more and more opportunities for the scientific community as well as industrial people. Based on all these assumptions, the present work includes experimental data of a work which explains the possibilities of room temperature ionic liquids (RTILs) as potential bulk liquid membranes (BLM) for extracting phenol and other phenolic compounds from the industrial affluents. Four high hydrophobicity ionic liquids namely: 1-hexyl-3-methylimidazolium hexafluorophosphate [Hmim][PF6], 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide [Bmim][NTf2], 1-butyl-3-methylimidazolium hexafluorophosphate [Bmim] [PF6] and 1-ethyl-3-methyimidazolium bis(trifluoromethanesulfonyl) imide [Emim][NTf2] were used for investigating the Phenol extraction efficiency and stripping efficiency. To provide a best comprehension of the influence of the phenolic structure as well as the nature of cation on the extraction ability of the ILs, we tried to understand the molecular interactions between the phenolic compounds and the solvents. The influence of hydrophobicity of ionic liquids and different kinds of anions on the extraction of phenol and efficiencies of stripping were investigated. All the experimental investigations performed here indicated that the only cation part of the ionic liquid is not an important aspect directly in this extraction, but the hydrogen bonding and the solute-solvent interactions play a significant role in the phenol removal process from aqueous phase to IL phase. First, the optimal conditions of operating (settling time and stirring) were analyzed for the clarity of the experiments performed. Concentration of NaOH in enhancing the performance of ionic liquids was also inspected here in this study. A binary mixture of ionic liquids (BMILs) membrane was examined for the optimized parameters, and the efficiency of phenol extraction was analyzed with the efficiency obtained for the single ionic liquid (SIL) membranes. The phenol concentration was determined by UV/visible spectrophotometer absorbance measurements. The highest phenol extraction efficiencies of 91% and 98.5%, were achieved by using [Bmim][NTf2] and [Bmim][NTf2+PF6] respectively, and the higher stripping efficiencies came up with 79% and 84% respectively, for [Emim][NTf2] and [Bmim + Emim][NTf2]. The results show that the binary mixture ionic liquid (BMIL) membrane is a better choice than single ionic liquid (SIL) membrane solvents. Hence, [Bmim] [(NTf2+PF6)] is an excellent selection as it provides high phenol stripping and extraction efficiencies with a minimal solvent loss and better stability in transport process. © 2020 Informa UK Limited, trading as Taylor & Francis Group. | Taylor and Francis Ltd. | 9593330 | |

The least square method is used as an error minimization technique for fitting the non-linear transcendental model equation of the solar panel to the measured I–V characteristics. Newton Raphson method is applied to solve the system of five non-linear equations which represent the error of each parameter. Initial guess values are calculated with an optimised algorithm depending on information extracted from the same measured data. MATLAB programming script was used in all implementation steps. This approach is useful for a wide variety of applications where the five SDM parameters have to be determined from the measured curves, particularly, for self-fabricated cells/modules or in case of no available datasheet. One of the strengths of this method is the higher level of accuracy because of the absence of mathematical simplifications and physical assumptions. The method was validated on different types of PV devices, including a crystalline silicon cell, a polycrystalline module, and an amorphous module by using measurement data obtained at a wide range of solar irradiance conditions and temperatures. © 2020 The Authors | King Saud University | 10183639 | |

In this study the density of ethyle methyl imidazolium tetrafluoro borate ionicliquids ([EMIM][BF4]) measured experimentally. In addition, the density (?) and the specific heat capacity (Cp) of the ionanofluid (INF) were calculated theoretically. The studied INF composed of multi-walled carbon nanotubes (MWCNTs) dispersed in the ionicliquid (IL) [EMIM][BF4] in the concentrations (0.5%, 1%, 3%, 5%, 7% and 9%). Scanning electron microscopy and differential scanning calorimetry measured for the used MWCNTs. The density and the specific heat capacity of pure [EMIM][BF4] and its INFs were plotted versus temperature in a graphs. The results show that the density of [EMIM][BF4] and its INFs decreased linearly with temperature. The density increased by 0.243%-3.968% for 0.5%-9% MWCNTs concentration in INFs, reaching maximum value of 1.329 g.cm-3 at 20 oC. In contrast the specific heat capacity of [EMIM][BF4] and its INFs increased linearly with temperature with an enhancement of about 0.417%-7.99% for 0.5%-9% concentration of MWCNTs reaching maximum value of 1.812 J/g.K at 358.15K with 9%MWCNT concentration. That’s mean the addition of MWCNT cause increasing both of the density and the specific heat capacity of INF. © 2021 Institute of Physics Publishing.

The modified moment features were used in accelerating the matching step of the Iterated Function System (IFS). The main disadvantage facing the fractal image compression (FIC) method is the over-long encoding time needed for checking all domain blocks and choosing the least error to get the best matched domain for each block of ranges. In this paper, we develop a method that can reduce the encoding time of FIC by reducing the size of the domain pool based on the moment features of domain blocks, followed by a comparison with threshold (the selected threshold based on experience is 0.0001). The experiment was conducted on three images with size of 512x512 pixel, resolution of 8 bits/pixel, and different block size (4x4, 8x8 and, 16x16 pixels). The resulted encoding time (ET) values achieved by the proposed method were 41.53, 39.06, and 38.16 sec, respectively, for boat, butterfly, and house images of block size 4x4 pixel. These values were compared with those obtained by the traditional algorithm for the same images with the same block size, which were 1073.85, 1102.66, and 1084.92 sec, respectively. The results imply that the proposed algorithm could remarkably reduce the ET of the images in comparison with the traditional algorithm. © 2021 University of Baghdad-College of Science.

Many metric learning algorithms learn a global distance function from data that satisfies the constraints of the problem. However, in many real-world datasets, where the discrimination power of features varies in the different regions of input space, a global metric is often unable to capture the complexity of the task. To address this challenge, local metric learning methods are proposed which learn multiple metrics across the different regions of the input space. Some advantages of these methods include high flexibility and learning a nonlinear mapping, but they typically achieve at the expense of higher time requirements and overfitting problems. To overcome these challenges, this research presents an online multiple metric learning framework. Each metric in the proposed framework is composed of a global and a local component learned simultaneously. Adding a global component to a local metric efficiently reduces the problem of overfitting. The proposed framework is also scalable with both sample size and the dimension of input data. To the best of our knowledge, this is the first local online similarity/distance learning framework based on Passive/Aggressive (PA). In addition, for scalability with the dimension of input data, Dual Random Projection (DRP) is extended for local online learning in the present work. It enables our methods to run efficiently on high-dimensional datasets while maintaining their predictive performance. The proposed framework provides a straightforward local extension to any global online similarity/distance learning algorithm based on PA. Experimental results on some challenging datasets from machine vision community confirm that the extended methods considerably enhance the performance of the related global ones without increasing the time complexity. © 2021 World Scientific Publishing Company. | World Scientific | 2180014 | |

Samples were collected from four stations in the Al-Gharraf River in southern Iraq during 2018-2019. A seasonal variation was observed in the concentrations of alkanes, which is the highest in the winter. The total alkanes concentrations were the lowest at 0.079 μg/g at station 1 in summer. The highest total concentration of alkanes was in station 3 in winter reaching 2.215 μg/g. There was a dominance of individual carbon compounds of C17, C19, and C21 indicating the source of hydrocarbon from phytoplankton, plant, and bacteria. The presences of carbon compounds higher than C25 reveals that organic matter is derived from land and aquatic plants. The results also indicate that the source of petroleum hydrocarbons in the sediments of the Al-Garraf River is a common biogenic and anthropogenic based CPI index and the pri/phy guide that was less than 1 in the second and third stations for all seasons, and greater than 1 in the first and fourth stations. © 2021 Iranian Society of Ichthyology. | Iranian Society of Ichthyology | 23830956 | |

One of the most common kinds of geosynthetic fabric utilized for soil reinforcement is geotextiles. This article investigates woven geotextile's potential benefits in enhancing the maximum loadcarrying capacity of footings resting upon silty sand soil. The foundation was constructed of a 10 mm thick strong carbon steel plate of 100 mm×100 mm. The factors examined in this research were the first geotextile layer's depth, the geotextile layer's width, the number of layers of reinforcing material, and the vertical spacing between geotextile layers. The impact of geotextile strengthening configurations on the loadcarrying capacity of strengthened soil foundations was also studied. The results of the experiments indicated that geotextile reinforced soil could help to grow the soil bearing capacity. The testing findings revealed that the system with three geotextile layers, 0.25B vertical distance among geotextile layers, and a geotextile width of 5B, B denotes the plate's width, achieves the most significant bearing capacity.

The great evolution of advanced wireless sensor networks has played a role in protecting wildlife. Recently wireless sensor networks are used to track animals in their habitat to follow the behaviour and lives of some endangered animals, but monitoring still difficult issues because may reason inside WSN: energy and deployment. Problems will appear another side the nature of wildlife: the size of animals will limit the technology that will use. When studying the types of networks the WSN will be the best solution to this case. In this paper WSN used to track the small type of birds calls “partridge” to protect birds and monitoring its behaviours. The proposed algorithm in this paper provide a new way to track and control a group of birds in their natural dwellings by using a hybrid wireless sensor network consist of set of predefined reference nodes, where sensitive information is sent to the base station through these beacon nodes, then resolve it and use it to the sacrificial location of the animals.

The debonding between CFRP and the surface of the beam is the main problem. Many researchers around the world have made extensive efforts to study the phenomenon of debonding for efficient applications. Based on these efforts and different related field applications, code previsions and various models have been proposed for predicting debonding failure. Two code previsions and three typical models are presented in the current study. ACI-440.2R 17, CNR-DT 200 R1/2013, Said and Wu, Lu et al., and Teng et al. have been used to estimate the flexural strength of RC beams strengthened by CFRP with and without grooves. Test results of eleven flexural beams strengthened by CFRP sheet/laminate using externally bonded reinforcement (EBR) and externally bonded reinforcement on grooves (EBROG) methods were used in the current paper. The performance and accuracy of each model were evaluated based on these test results. Most of the prediction models that used in this study give a closer prediction of the flexural strength of beams strengthened by EBR compared to that of the beams strengthened by EBROG. Finally, the prediction results of CNR-DT 200 R1/2013 were the most accurate and approval with test results compared with other models in the current study © 2021 Riyam J.

The geometry consists of a half-cylinder containing paraffin with a uniform constant temperature and an insulating wall. Also, Darcy model and buoyant force due to density changes are considered in this simulation. The effects of the presence of aluminum foam with porosity ε=0.8,and0.95 and difference temperature ΔT=5,10,and15 have been studied on the melting fraction of PCM, temperature and streamlines contours and heat flux of cylinder's surface. The observations show that enhancement of porosity 0.8 to 0.9 increases the volume of PCM 11.7%, and reduces time of melting process 30.8% for ΔT=15. Moreover, increment of ΔT=5to15 leads to decrease time of melting process 71.8% when porosity is 0.95. © 2021 The Authors | Elsevier Ltd | 2214157X | |

Also, an oblique magnetic field (MHD) has been implemented to improve and control the flow. The unstructured triangular mesh and FVM with SIMPLE algorithm have been employed for discretization and coupling of pressure and velocity equations. In this simulation, the parameters of Hartmann, Rayleigh numbers and volume fraction of nanoparticles have been investigated on temperature contours, flow pattern, and hot wall Nusselt number. The observations show that, increasing the volume fraction increases the Nusselt number at low Rayleigh numbers. Moreover, the Nusselt number is inversely related to the Hartmann number for high Rayleigh numbers. © 2021 | Elsevier Ltd | 2214157X | |

The continuity-current equation is coupling with the density matrix equations, which are solved numerically to obtain the quantum efficiency. This modeling will calculate the momentum matrix elements of transitions, consider the orthogonalized plane wave for wetting layer- quantum dot transitions, and covers more characteristics than the rate equations by considering all the possible interactions between the states. The results simulate both the excitonic and nonexcitonic (electron-hole) cases. The work emphasizes adding the double quantum dot layer, which gives flexibility in choosing the energy difference between states controlling the recombination rates. The work refers to the importance of orthogonalized plane-wave in solar cell work. In both models, the band-band recombination is high for slight energy differences between the states, confirms the importance of the double quantum dot system to manipulate transitions between states and obtain higher rates. For the electron-hole model, the leakage is high due to the fast recombination of holes. The discrimination between occupations of states is increasing under the excitonic model due to growing hole occupation. In both models, reducing the quantum dot - quantum dot recombinations and increasing all other recombinations will increase the quantum efficiency. The high quantum dot band-to-band rate increases the quantum efficiency. In the excitonic model, lower rates than in the electron-hole model are enough for high quantum efficiency. © 2021 IOP Publishing Ltd. | IOP Publishing Ltd | 318949 | |

Hence, the target of the current research is to specify the exergetic and economic aspects of an innovative electricity and cooling cogeneration system comprising a dual-flash binary geothermal power plant and an ejector refrigeration unit. The essential point of this study is the smart use of the total capacity of a medium-temperature geothermal source to produce energy-based products and eliminate the weakness of the conventional setups, increasing the exergy and exergoeconomic performances. A parametric study has been implemented to analyze the effect of several main parameters on the vital variables including efficiencies, exergy destruction rate, sum unit exergy cost, investment cost rate, and exergoeconomic factor. Besides, a multi-objective optimization in different cases has been applied to the calculations through a non-dominated sorting genetic algorithm II (NSGA-II) to achieve an optimal design. The results showed that the performance of the system was more sensitive to changing the separators’ operating pressure of the plant. Likewise, the optimum exergy efficiency and optimum unit exergy cost of the system were found to be 12% and 0.0043 $/kWh through the exergy/cost multi-objective optimization case, correspondingly. © 2021 Elsevier Ltd | Elsevier Ltd | 22131388 | |

Indeed, the whole system has been devised regarding the multi-heat recovery technique and smart management of products through a structural modification. To emphasize the ability of the newly designed system in this work, the data of the Sabalan geothermal plant in Iran has been used as a case study. Subsequently, the feasibility of the proposed multigeneration system has been examined by the modified specific exergy costing (M-SPECO) method, characterizing the exergetic and cost aspects of the system. The M-SPECO method is recognized as an energy level-based cost scrutiny technique to evaluate energy conversion systems. Accordingly, the sensitivity study through single and dual parametric analyses has been implemented, wherein separator 1 pressure was the main parameter. Likewise, the non-dominated sorting genetic algorithm-II (NSGA-II) method has been applied to optimize the calculations and reveal the optimum conditions and results. In this way, the achieved optimum exergy efficiency of the system was calculated as 47.25%, followed by a value of 7.66 $/GJ for the modified overall unit cost of products. © 2021 Elsevier Ltd | Elsevier Ltd | 9601481 | |

The Buongiorno model with the effects of Brownian and thermophoresis motion is considered to nanoparticles distribution inside the chamber. The geometry consists of a square chamber with two cylinders on the right and left sides as heater and cooler in order to create the buoyancy force, respectively. These cylinders represent hot and cold pipes, and the walls of the chamber are heat and mass insulation. the FVM with SIMPLE algorithm are used for velocity and pressure coupling. In current two-phase simulation, the effects of Rayleigh number, Hartmann number, inclination angle of chamber and volume fraction on streamline contours, isothermal lines, Lorentz force lines, nanoparticle distribution and Nusselt number are investigated. By modeling the motion of nanoparticles and evaluating it, a nanoparticle transport zone was observed. The diffusion effects of thermophoresis were significant in this zone. The nanoparticles were thrown from the hot cylinder to the cold cylinder. The application of a magnetic field enlarged the nanoparticle transport zone. However, increasing the Rayleigh number and decreasing the inclination angle of the enclosure caused the nanoparticles to disperse evenly. © 2021 The Authors | Elsevier Ltd | 2214157X | |

In this study, 4-methyl-2-(4-methylpiperazinyl)pyrimido[4,5-b]benzothiazine (4-MMPB) and its two analogs, 4-propyl-2-(4-methylpiperazinyl)pyrimido[4,5-b]benzothiazine (4-PMPB) and 4-ethyl-2-(4-methylpiperazinyl)pyrimido[4,5-b]benzothiazine (4-EMPB), were proposed to have anti-tumor properties in prostate cancer. Methods: After synthesizing the compounds, cytotoxic effects of 4-MMPB and its two analogs against PC-3 cancerous and HDF normal cells were investigated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay and then mechanism of cell death was assessed by flow cytometry. Finally, the anti-tumor effects of the mentioned compounds were investigated in an immunocompromised C57BL/6 mouse model. Results: 4-PMPB and 4-EMPB had similar anti-cancer effects on PC-3 cells as compared with 4-MMPB, while they were not effective on normal cells. Moreover, apoptosis and ferroptosis were the main mechanisms of induced cell death in these cancerous cells. Furthermore, in vivo results indicated that both analogs had similar anti-cancer effects as 4-MMPB, leading to delayed tumor growth without any noticeable side effects in weight loss and histological investigations. Conclusion: Thus, our results suggest that specific targeting of lipoxygenases via 4-MMPB analogs can be considered as a treatment of choice for PC therapy, although it requires further investigations. © 2021, The Author(s). | BioMed Central Ltd | 1790045X | |

This modification consists of the Laplace transform method, HPM, and a control parameter δ. This control convergence parameter δ in this new modification helps in adjusting and controlling the convergence region of the series solution and overcome some limitations of HPM and HPTM. The δ-HPTM and q-homotopy analysis transform method (q-HATM) are considered to study the generalized time-fractional perturbed (3 + 1) -dimensional Zakharov–Kuznetsov equation with Caputo fractional time derivative. This equation describes nonlinear dust-ion-acoustic waves in the magnetized two-ion-temperature dusty plasmas. The selection of an appropriate value of δ in δ-HPTM and the auxiliary parameters n and ħ in q-HATM gives a guaranteed convergence of series solution, but the difference between the two techniques is that the embedding parameter p in δ-HPTM varies from zero to nonzero δ, whereas the embedding parameter q in q-HATM varies from zero to 1n,n≥1. We examine the effect of fractional order on the considered problem and present the error estimate when compared with exact solution. The outcomes reveal complete reliability and efficiency of the proposed algorithm for solving various types of physical models arising in sciences and engineering. Furthermore, we present the convergence and error analysis of the two methods. © 2021, The Author(s). | Springer Science and Business Media Deutschland GmbH | 16871839 | |

The use of special technologies of plating high-quality selective coatings on the heliocollector absorber makes it possible to substantially increase the coefficient of conversion of the solar radiation incidence flux. The research data are presented on the flat heliocollectors, which serve to heat-up a heat carrier used mainly for the needs of the hot-water supply for the individual consumers. In the performed experiments, the flat solar collectors were equipped with copper and stainless-steel absorbers. The studies showed that the heliocollectors can ensure better use depending on the operation mode of the entire system of the solar hot-water supply. The experiments were carried out by the staff of the Renewable Energy Sources and the Electric Energy and Networks department of Sevastopol State University at the Institute of Nuclear Energy and Industry. It was shown that the conversion coefficient of the solar power plants for the direct conversion of the radiation flux into thermal energy is far more energy efficient compared to that of the solar electric generation systems. © 2021, Allerton Press, Inc. | Pleiades journals | 10683755 | |

Accordingly, its optimization is described for various cases employing a genetic algorithm and adopting exergetic and economic approaches. In this way, the net generated electricity, the overall exergy efficiency, and total cost per unit exergy are chosen as the objective functions. The conventional CCHP setup comprises a solar subsystem including high-temperature solar collectors in arrangement with hot and cold storage tanks, an organic Rankine cycle (ORC), a heating production heat exchanger, and a single-effect absorption chiller. In addition to the solar subsystem, the modified setup embraces three heating production heat exchangers, a double-effect absorption chiller, and two regenerative ORCs. Indeed, the use of regeneration in the ORC provides the possibility of establishing two regenerative ORCs (RORCs) along whit a multi-heat recovery situation at the defined framework. Three different solar operational modes, i.e., high, low, and zero radiation statuses during a day are considered to analyze and compare the conventional and modified systems under identical conditions through a comprehensive parametric study. Taking into account the parametric study results, the oil mass ratio of the solar subsystem has a remarkable impact on the exergy and cost criteria of the system throughout the day. Moreover, the modification process provides the best exergetic and economic performances. This capability ascends the overall exergy efficiency by 0.8, 0.6, and 0.4 percent-points, and the exergoeconomic factor by 0.4, 0.9, and 2.1 percent-points for the aforementioned solar operation modes, respectively. © 2021 | Elsevier Ltd | 23527102 | |

It is one of the most important diagnostic methods in sleep research and must be carried out with a high degree of accuracy because any errors in the scoring in the patient's sleep EEG recordings can cause serious problems. The aim of this research is to develop a new automatic method for detecting the most important characteristics in sleep stage 2 such as k-complexes based on multi-domain features. In this study, each EEG signal is divided into a set of segments using a sliding window technique. Based on extensive experiments during the training phase, the size of the sliding window is set to 0.5 s (s). Then a set of statistical, fractal, frequency and non-linear features are extracted from each epoch based on the time domain, Katz's algorithm, power spectrum density (PSD) and tunable Q-factor wavelet transform (TQWT). As a result, a vector of twenty-two features is obtained to represent each EEG segment. In order to detect k-complexes, the extracted features were analysed for their ability to detect the k-complex waveforms. Based on the analysis of the features, twelve out of twenty-two features are selected and forwarded to a least square support vector machine (LS-SVM) classifier to identify k-complexes in EEG signals. A set of various classification techniques of K-means and extreme learning machine classifiers are used to compare the obtained results and to evaluate the performance of the proposed method.The experimental results showed that the proposed method, based on multi-domain features, achieved better recognition results than other methods and classifiers. An average accuracy, sensitivity and specificity of 97.7 %, 97 %, and 94.2 % were obtained, respectively, with the CZ-A1 channel according to the R&K standard. The experimental results with high classification performance demonstrated that the technique can help doctors optimize the diagnosis and treatment of sleep disorders. © 2021 Elsevier B.V. and Japan Neuroscience Society | Elsevier Ireland Ltd | 1680102 | |

Materials and Methods: In the first experiments rats were injected with histamine 5 mg/kg i.p., and blood samples were collected to determine the effect of histamine on serum level of adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), prolactin, FSH, and luteinizing hormone (LH) after 10, 20, and 30 min of histamine injection. In the second experiments, rats were treated with (H 1 blocker), chlorphenramine 10 mg/kg, i.p. or (H 2 blocker), cimetidine 80 mg/kg, i.p. respectively, and after 30 min they were injected with histamine and blood samples were taken 30 min after the injection of histamine to determine the same hormones. Results: Histamine significantly elevated serum ACTH and LH level, and these stimulatory effects were inhibited by both H1 and H2 receptor blockers. However, histamine significantly inhibited the serum level of thyroid-stimulating hormone and this inhibitory effect was blocked by H2 receptor blocker, while it showed no effect on the secretion of both prolactin and FSH, although H2 blocker significantly decreased prolactin level and H1 blocker significantly elevated FSH level. Conclusion: The results clearly indicated that histaminergic pathways were involved in the anterior pituitary secretion. © 2021 Published by Scientific Scholar on behalf of Indian Journal of Physiology and Pharmacology. | Scientific Scholar | 195499 | |

Therefore, the aim of the present study was to check the prevalence and resistance patterns of uropathogens in the community acquired UTIs. Methods: A total of 7132 urine samples were combined from male 3131 (43.9%) and female 4001 (56.1%) outpatients suspected of having UTIs, respectively over a three-year period and cultured on routine culture media. The bacteria have been identified using basic biochemical tests, and sensitivity to various antibiotics was determined by the method of disk diffusion. Results: Of 7132 urine samples 797 (11.2%) yielded significant uropathogens. Among the bacterial species, Escherichia coli was the major causative agent of UTIs for both gender (63.7%), followed by Klebsiella spp (20.8%), Enterococcus faecalis (5.3%), Pseudomonas spp (4.1%), Proteus spp (3.1%), Enterobacter spp (1.5%), Candida albicans (0.6%), Staphylococcus saprophyticus (0.5%), Providencia spp (0.1%) and Staphylococcus aureus (0.1%).

Dept., University of Thi-Qar, Nasseriya, Iraq | The thermal and hydraulic performance of a twisted circular tube with an obstacle attached to the internal surface along the tube length (L = 1000 mm) is numerically analyzed in this work. The considered configuration is investigated by varying obstacle height ratio (OHR = h/D) which is the obstacle height (h) to the tube diameter (D = 20 mm) while obstacle thickness is kept constant under turbulent flow regime, i.e. Reynolds number 4000 ≤ Re ≤ 10,000 for air as working fluid. Various cases of OHR are triggered 0.0, 0.125, 0.25, 0.375, 0.5 and 0.625 respectively. The results show that the larger OHR gives a higher Nusselt number and vice versa due to increasing swirling power to the air in the tube. However, a higher friction factor is the penalty associated with this large obstacle. Recorded thermal performance factor TPF is beyond unity for all cases. The optimal value of TPF is observed at OHR = 0.625 which is recommended for high heat transfer rate requirement. Corresponding TPF = 2.07 at Re = 4000 and TPF = 1.69 at Re = 10,000.

The tensile reinforcements of the specimens were subjected to 7% and 20% corrosion rates. Steel fibres in volume fractions of 0.8%, 1.2%, and 1.8% were added to concrete matrices. Six of the beam specimens were mixed with pre-corroded steel fibres at a corrosion level of 50% to study the hybrid effect of their corrosion and the longitudinal reinforcement on shear performance. The test results showed that adding the fibres improved the shear capacity, and reduced crack initiation and propagation due to corrosion, mode of failure, and deflection. The shear capacity of the non-corroded SFRC beams increased by about 68%, 72%, and 82% for the 0.8%, 1.2%, and 1.8% volume fractions of steel fibre, respectively, compared to RC beams without fibre. Also, the mode of failure changed from brittle shear failure to ductile flexure failure for SFRC beams. A 1.8% volumetric ratio of steel fibres was very useful in terms of enhancing shear behaviour. The corrosion in the tensile reinforcement of the beams reduced the shear strength by 6%–8% for the corrosion rates of 7% and 20%, respectively; however, the corrosion also reduced the maximum loading by 10%–22%. Furthermore, the corroded both steel fibres and corroded rebars reduced loading by 6%–37%. As a result, it was concluded that the steel fibres can enhance the performance of the beams for shear even in a harsh environment. Finally, the results of some models obtained from the literature to compute the shear strength of RC and SFRC beams with and without corrosion effect were compared with the experimental results of this study. © 2021 Institution of Structural Engineers | Elsevier Ltd | 23520124 | |

The calculation was preformed based on density functional theory (DFT) implemented by SIESTA. The results reveal that the transmission calculations T(E) of all five monomers/dimers show no spin dependent with highest value for monomer structure around Fermi energy. The phthalocyanine monomer structures show higher conductivity calculation around the Fermi energy in comparison to conductivity values of phthalocyanine dimer structures. Further, thermoelectric properties such as Seebeck coefficient (S), thermal conductance (k) and figure of merit (ZT) are also presented. It is found that the highest positive Seebeck coefficient (S) value belongs to zinc phthalocyanine monomer, while the highest negative (S) value belongs to free base phthalocyanine dimer structure over a wide range of Fermi energies. Moreover, zinc phthalocyanine monomer structure shows highest thermal conductance (k), while phthalocyanine dimer structures exhibit lowest thermal conductance (k) in the vicinity of DFT predicted Fermi energy. As a result, high room-temperature figure of merit (ZT ≈1.7) is reported for free base phthalocyanine dimer, which might be due to the low thermal conductivity and high Seebeck coefficient and electrical conductance values, which makes it a preferred candidate for potential thermoelectric applications. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

The study investigates the transmission and conductance characteristics of Bare-Pc without central metal ion and with different transition metal ions at the centre of (Pc) such as (Mn, Co, Ni, and Zn) in two different molecular configurations, cis and trans. The results reveal that the conductance changed by varying the transition metal-centre in the order of Co > Ni > Zn in trans, and closely similar pattern Co > Ni > Mn in cis with higher values in trans configuration. This reflects the correlation between the spin-dependent transport properties with the transition metal-centre type and the molecular structure. Further, thermoelectrical properties such as thermal conductance (k), Seebeck coefficient (S) and figure of merit (ZT) are investigated. It was found that (k), (S) and (ZT) have higher values in case of trans configuration for Co-Pc, Ni-Pc and Zn-Pc structures. Thus, by varying the transition metal-centre type and the molecular configuration of (Pc) molecule, transport properties can be tuned to produce a good value of the transmission and electrical conductance, thermal conductance, Seebeck coefficient, and figure of merit of the (Pc) molecular junction for potential high conductance and efficient thermoelectric applications. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

Today, cysts’ rupture or content leakage during surgery and involvement of organs adjacent to the organ in-volved, and consequently secondary cysts, are the major concern for hydatid cyst surgeons. There-fore, using scolicidal substances such as hypertonic saline 20%, silver nitrate and formalin has been considered to reduce the risk of protoscoleces spread and recurrence of disease in recent years. The current work was designed to assess the antiparasitic effects of Capparis spinose L. extract against hydatid cyst protoscoleces. Methods: Collected protoscoleces from liver fertile hydatid cysts of infected sheep were exposed to the different concentrations of the essential oil (150, 300, 600 mg/mL) for 5-60 min in vitro and ex vivo. Then by using the eosin exclusion assay, the viability of protoscoleces was studied. The primary phytochemical analysis of the C. spinosa extract was done to assess the presence of tannins, alkaloids, saponins, flavonoids, terpenoids and glycosides. Results: C. spinosa extract exhibited a powerful protoscolicidal activity in vitro so at the dose of 300 and 600 mg/ml, it entirely eliminated the parasite after 10 and 5 minutes; whereas at lower dos-es, it demonstrated weak protoscolicidal activity. In ex vivo assay, no similar effect to in vitro assay was observed, so more time was required to show a potent protoscolicidal activity. C. spinosa ex-tract, at the concentrations of 300 and 600 mg/mL after an exposure time of 20 and 12 min, killed 100% of protoscoleces within the hydatid cyst, respectively. The findings of primary phytochemi-cal screening of the C. spinosa extract demonstrated the existence of flavonoids, tannins, ter-penoids, glycosides and alkaloids in this plant. Conclusion: The obtained results in vitro and ex vivo exhibited potent protoscolicidal effects of C. spinosa extract particularly at the concentrations of 600 and 300 mg/ml, which entirely eliminated the parasite after 5-20 min exposure. However, more supplementary works are required to verify these findings through assessing in animal models and clinical subjects. © 2021 Bentham Science Publishers. | Bentham Science Publishers | 15701638 | |

It is performed by depositing a main wire plus a cold feed wire melted by the electric arc heat. In the present work, a new experimental set-up was developed, which consists of a MIG-welding source and an external cold wire feed unit plus a 3-axis machine. The main intent of the current paper is to investigate the microstructural and mechanical properties of austenitic stainless steel grade 309L deposited parts. The result showed that the value of the wire feed ratio (WR) plays an important role in both microstructure and mechanical properties. The microstructure mainly consists of two phases ferrite and austenite as predominant phases throughout the parts. Widmansttãten austenite structure that is denoted as (W) this appears in the white region, and Vermicular delta ferrite (V) appears as the dark-etching phase. The tensile test results showed the UTS value increased by 17.36% in the longitudinal direction when using cold feeding, while it increased by 4.39% in the vertical direction.

However, there is no work has been investigated in the literature to provide unified statistics of the product and the ratio of the products that can be used for a wide range of non-composite and composite fading conditions. Accordingly, in this paper, the statistical properties, namely, probability density function (PDF), cumulative distribution function (CDF), and moment generating function (MGF) of the product and the ratio of the product of independent and non-identically distributed (i.n.d.) mixture Gamma (MG) RVs are derived. A MG distribution has been widely employed to approximate with high accuracy most of the conventional fading models, for example, Rayleigh, Nakagami-m, Nakagami-q (Hoyt), and Nakagami-n (Rician) as well as the generalised composite fading channels, such as, generalised- (Formula presented.) /gamma, (Formula presented.) /gamma, and (Formula presented.) /gamma. Hence, the derived PDF, CDF, and MGF are utilized for the Beaulieu–Xie and (Formula presented.) shadowed fading channels that have not been yet presented by the previous works due to mathematical intractability of their statistics. Thus, the equivalent parameters of a MG distribution for these channels are given. To this end, simple closed-form mathematically tractable expressions of the performance metrics are obtained. The derived statistics are applied to analyse the outage probability (OP), the average error probability for different modulation schemes, the effective rate (ER) of wireless communication systems and the average area under the receiver operating characteristics (AUC) curve of energy detection over cascaded fading channels. Moreover, the OP of the multi-hop communications systems with co-channel interference (CCI), both the lower bound of secure OP (SOPL) and probability of non-zero secrecy capacity (PNSC) of the physical layer security (PLS), and the outage and delay-limited capacities of CRNs are studied via using the statistics of the ratio of the product of MG variates. A comparison between the numerical results and the Monte Carlo simulations is presented to verify the validation of our analysis. © 2021 The Authors.

First, the RollerFORM and Omniscan equipment were sufficiently used to identify the delaminations. Second, in conjunction with guided waves, the developed imaging method was successfully used to detect and quantify the interested delaminations. The tuning curves were determined experimentally to define the dominant Lamb wave modes of incident waves. Third, multi-physics three-dimensional finite element simulations of propagating and interacting Lamb waves with delaminations were implemented to extract the wavefield data for wavenumber analysis. The experimental part was conducted to validate the numerical results using SLDV. The effect of the delamination depth on the trapped waves generated over the delamination region was studied numerically and experimentally. The results showed that trapped waves could be affected by the delamination depth. Both numerical and experimental results demonstrated that the near surface delamination has strong trapped waves over the delamination region while the far surface delamination has weak trapped waves. The energy distribution maps of numerical and experimental wavefields data sufficiently quantified the interested delaminations. A good agreement was achieved between the numerical and experimental results. © The Author(s) 2020. | SAGE Publications Ltd | 1045389X | |

The limit equilibrium method is used considering the soil failure theory under a rough based strip foundation. Three equations are developed to determine the values of the efficiency factors resulting from the effect of interference of foundations for the surcharge, cohesion, and weight. The effect of variable factors on the equations, which represent the angle of friction, the distance between the foundations and the width of the foundations has been studied, and the results have shown that when the interference occurs between the foundations, the soil bearing capacity increases with the increase in the angle of friction and decrease the distance between the foundations, while the change in the width of the foundations has just an effect on interference factor related to the soil weight, ζ γ . Comparing the results of the present mathematical model with the results of available theoretical analyses and previous experimental studies shows acceptable and reliable agreement. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

These molecular junctions have been explored in two different configuration trans and cis conformation. In this work, we investigate the spin properties, in addition to thermoelectrical properties for all cases. Our results show that there is a variation in spin properties in staggered ferrocene when move from trans to cis configuration. However, in eclipsed ferrocene case there is no spin effects. Moreover, the room temperature electrical conductance in cis staggered ferrocene case is higher than other cases near the DFT Fermi energy. Furthermore, the thermopower of these junctions are rather high ranging about 150 µV/K. However, the thermoelectric figure of merit ZT of staggered ferrocene in cis configuration has the highest value with 1.06. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

In this work method was used Taguchi to study the effect of operating transactions on the surface quality of the operator (the barrel). In this study four parameters were used which are sample length (L), sample diameter (D), feed rate (F), and cut depth (T). The objective of this work is to improve the quality of the surface of the machine through the control of the main input parameters for the process of turning aluminum and steel materials. It was selected orthogonal group L9 to study the impact of key factors on the variable response, i.e. barreling. The contribution of key factors and their interaction with the optimal level were determined using ANOVA. The results showed that the cutting depth was 0.5 mm and the feeding rate was 0.5 mm/roll yield minimum barreling. In addition, ANOVA results indicated that among four major factors, the specimen diameter and cut depth significantly contributed to reducing barreling. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

In this regard, the current paper is motivated to devise and evaluate a novel geothermal-driven multigeneration system under the effect of various working fluids. The proposed system consists of a flash-binary geothermal power plant, an organic flash cycle (OFC), a power/cooling subsystem (an organic Rankine cycle (ORC) and a thermoelectric generator incorporated with a compression refrigeration cycle), and freshwater and hydrogen production units utilizing a humidification-dehumidification desalination unit and a low-temperature electrolyzer. Considering the design potential of the OFC and ORC, four different environmentally-friendly working fluids, i.e., R123 and R600 in the OFC and R1234yf and R1234ze(e) in the ORC are selected and classified in four groups to introduce the best one, under the energy, exergy, and economic (3E analysis) approaches. Also, the whole system is optimized through a genetic algorithm, respecting the optimal solution for the energy efficiency and unit exergy cost of the products. According to the results, R123/R1234ze(e) shows the highest cooling, hydrogen, freshwater production rates, and energy efficiency. Likewise, the maximum power generation and exergy efficiency belong to R600/R1234ze(e). Moreover, R600/R1234yf has the lowest unit exergy cost of products. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

In this regard, this study supports a comprehensive evaluation and multi-criteria optimization of a novel poly-generation plant embracing geothermal energy from thermodynamic and thermoeconomic perspectives. Hence, the utilization of modified subsystems and smart use of multi heat recovery processes are projected and appraised. In this regard, the plant consists of a double-flash binary geothermal subsystem, an organic Rankine cycle in combination with an ejector refrigeration cycle considering a zeotropic working fluid (a mixture of pentane and R142b), a heating production heat exchanger, and a proton exchange membrane electrolyzer with the combined production of cooling, heating, power, and hydrogen. The crucial thermodynamic and thermoeconomic variables are investigated against key parameters and concluded that the sensitivity of outcomes is more evident with the variation in zeotropic working fluid composition and the vapor quality at the heating production heat exchanger's outlet.

The studied molecules demonstrate good properties with low energy gap, small exciton binding energy, high open circuit voltage and broad absorption spectrum. The molecular donor (MD5) is identified as the promising candidate of the organic solar cell because of the most enhanced in optical absorption, energy gap, open circuit voltage, energy driving force, exciton binding energy. © 2021, Pleiades Publishing, Ltd. | Pleiades journals | 19907931 | |

Load-deflection curves, modes of failure and the pattern of the cracks are studied. Also, the influence of compression strength of concrete, the configuration of CFRP (U shape and 2 side bond shape) and shear span to depth ratio (a/h ratio). The results show that the shear capacity of RC beams strengthened by CFRP increased by a maximum percentage of up to 111.7% compared to the unstrengthened beam. Also, it is found that by increasing the compressive strength of concrete from 40 MPa to 65 MPa the load-carrying capacity increases by 28% and the stiffness also increased, while the decrease of shear span to depth ratio from 1.66 to 2.33 leads to increasing the shear capacity by 23%. The maximum load of beam strengthened with U shape increased by up to11.5% when compared with the same beam strengthened with two side bond shapes of CFRP. However, the gain in the strength was reached to 22.7% for beams strengthened with CFRP laminate compare to unstrengthened beams. The strengthening of RC beams by CFRP laminates using the near surface mounted (NSM) technique is more efficient than the externally bonded reinforcement (EBR) technique for all beams in the shear behavior. The finite element models provide a good level of accuracy compared to experimental results and ACI-440. © 2021 Potificia Universidad Catolica de Chile.

Strength reduction of UHPCs may amount to as high as 80 percent after exposure to 800?. A sum of four UHSC mixes was synthesized and evaluated in this study after getting exposed to extreme temperatures that reach 1000°C. Steel and polypropylene (PP) fibers were used in this experiment. A total of four mixes were made of UHSC without fibres as a control mix (UHSC-0), UHSC with 2% steel fibres (UHSC-S), UHSC with 2% PP fibres (UHSC-P) and UHSC with 1% steel fibres + 1% PP fibres (UHSC-SP). Workability, direct tensile strength, compressive strength, and splitting tensile strength were examined. Particularly, emphasis was devoted to explosive spalling since UHPCs are typically of compact structure and hence more prone to explosive spalling than other concretes. It was determined that the mixture UHSC-SP had high fire resistance. Following exposure to 1000?, this mixture preserved a residual compressive strength of 36 MPa, splitting tensile strength of 1.62 MPa and direct tensile strength of 0.8 MPa. On the other hand, UHSC-P also had good fire resistance while UHSC-0 and UHSC-S experienced explosive spalling after heating above 200?C. The incorporation of steel fibers in UHSC-S and UHSC-SP mixtures reveals higher tensile and compressive strength findings at different elevated temperatures as compared to UHSC-0 and UHSC-P. In addition, the result of direct tensile strength appears to be lower than splitting tensile strength at different raised temperatures. © 2021 Lavoisier.

Magyarország, Győr, 9024, Hungary; Kovács, T.A., Donát Bánki Faculty of Mechanical and Safety Engineering, Óbuda University, Budapest, 1081, Hungary | In this work, selective laser melting of Ti6Al4V (Ti64) and 2 wt.% hydroxyapatite (HA) composites was performed with the purpose of osseointegration enhancement and biological fixation between implants and bone tissue. The microstructural evolution and mechanical properties were analyzed by using X-ray diffraction (XRD), optical microscopy (OM), a scanning electron microscope (SEM) equipped with (EDX) and (EBSD) systems, microhardness, nanoindentation, and tensile testing. The results showed that the Ti64-2%HA composite components exhibited complicated manufacturing behavior, which could be correlated with the decomposition of HA. The microstructure was found to mainly consist of α Ti with a small amount of HA distributed along grain boundaries. Furthermore, the interaction between Ti64 and HA leading to the formation of Ti3P, TixO, P, and CaTiO3 phases, resulted in poor tensile properties, as compared to pure Ti64 components. Conversely, the tensile properties of SLM Ti64-2%HA composite components were significantly higher than human bone reported previously in the literature. © 2021 by the authors.

The main part of generated energy is consumed by cooling and heating systems. One of the well-known approaches to implemented heating and cooling system is earth to air heat exchanger (EAHE) system. This system is effective passive heating and cooling systems which can be used with poultry houses and building. This research studies numerically the effect of mass flow rate on the overall performance of earth to air HE for poultry houses. Four parameters (mass flow rate, required rate, required cooling load and pipe lengths) are selected under environment of Nasiriyah city (a city located in the south of Iraq). The study is conducted using PVC material. The study has been done during summer season. The suggested numerical model has been tested and validated using existing approaches selected from literature review papers. This test shows good agreement with results of selected papers. Moreover, validation and simulation results showed that the required cooling load increased with increasing mass flow rate. Also, with the increasing length of pipe of EAHE, the inflow temperature compared to the space temperature is decreased. However, the overall performance factor of EAHEs decreases by the increase of length of pipe and mass flow rate. Which indicate the possibility of using the earth to air heat exchanger for cooling and heating poultry houses and reduce the use of electrical energy. © 2021.

In the current study, the removal efficiency of Cd (II) and Ni(II) from aqueous solution was investigated by carbonaceous magnesium oxide. Three types of C-MgO adsorbents were synthesized via pyrolysis of prepared magnesium complex Mg(acac)2 at three temperatures. Fabricated C-MgO adsorbents were characterized by XRD, SEM, and BET. XRD results revealed that the synthesized adsorbents consist of only magnesium oxide and carbon phase without any impurities. SEM technique used to characterizes the surface morphology of C-MgO samples. N2 adsorption-desorption isotherm used to calculate the BET surface area of prepared samples. The SEM results had a good agreement with BET measurement which improved that the high temperature increase the particles size and reduce the surface area. The adsorption studies showed that the carbonaceous magnesium oxides have good removal effeciency for Cd (II) and Ni(II) removal from aqueous solution and kinetically follow the pseudo-second order model. © 2021 National Information and Documentation Center. | NIDOC (Nat.Inform.Document.Centre) | 4492285 | |

The parameters under study are the frequency and coupling interaction on the electric current, the rectifying ratios, and the electrical conductance. Depending on the frequency value, the current rectifying ratio increase slightly between coupling interactions. The electromagnetic field causes reducing the conductance gap and increasing the amplitude of the electric current. The electromagnetic field controls the position, height, and width of conductance peaks. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

Scope and approach: Natural compounds present in herbs- and spices-derived extracts, essential oils and other secondary metabolites from plants, bacteria and enzymes are currently gaining ground and are still largely underused. Their use as replacements for synthetic additives can open new frontiers in safety and quality preservation in food, as they are relatively safer and do not pose health risks to consumers. This review provides updated information on the use of preservative solutions from natural sources on foods, especially perishable ones, also discussing the use of new packaging technologies. Key findings and conclusions: Although the use of additive sources of natural origin has received increasing interest, some adverse effects on organoleptic properties may also result from its use. Thus, despite the latest advances, more studies are still needed on the optimization of the quantities to be used to effectively inhibit spoilage and pathogenic microorganisms without affecting the organoleptic properties of foods; otherwise, these natural food additives can be encapsulated for inclusion in foods as preservatives. © 2021 Elsevier Ltd | Elsevier Ltd | 9567135 | |

Let G = (V,E) be a finite, simple, and undirected graph without isolated vertex. A dominating subset D aS V (G) is a total pitchfork dominating set if 1 ≤|N(u) a V - D|≤ 2 for every u D and G[D] has no isolated vertex. D-1 aS V - D is an inverse total pitchfork dominating set if D-1 is a total pitchfork dominating set of G. The cardinality of a minimum (inverse) total pitchfork dominating set is the (inverse) total pitchfork domination number (γpf-t(G)) γpft(G). Some properties and bounds are studied associated with maximum degree, minimum degree, order, and size of the graph. These modified domination parameters are applied on some standard and complement graphs. © 2021 World Scientific Publishing Company. | World Scientific | 17938309 | |

The scientific impact of the current work has been improved considering the features of Sabalan flash-binary geothermal wells in Iran as a real model through a case study. In addition to designing a novel setup, the smart use of multi-heat recovery technique, modifying the base cycle, and utilizing a part of generated distilled water to produce hydrogen by the electrolyzer are the other structural originalities, distinguishing the current work from the previous studies. The suggested system is scrutinized via a parametric study and optimized based on a genetic algorithm. The parametric study demonstrated that the highest sensitivity of varying the performance criteria of the whole system is attributed to the change in flash tank pressure. Moreover, the multi-objective optimization led to achieving the exergy efficiency and trigeneration gain output ratio as 51.3% and 1.7 for the system, respectively. Furthermore, the system was able to produce 4795 kW of power, 5.3 kg/h of hydrogen, and 19.9 kg/s of distilled water. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

In this situation, the interfaces may expand, shrink or remain stationary relying on the competition between these two factors. In this paper, we concentrate on three regions to classify the behavior of local solutions near the asymptotic interface in the irregular domain. In the first and second regions, the slow diffusion dominates over the convection term with expanding interfaces under some restrictions. In the third region, the slow diffusion dominates over the convection, but the interfaces have a waiting time. In our proof, the rescaling method and blow-up techniques are applied. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

In this paper, the newly technique of hybrid particle swarm optimization (PSO) algorithm is proposed. This technique is a dynamic and static topology with a PSO algorithm, which called dynamic and static PSO (DS-PSO) algorithm. In the simulation, the low-pass IIR digital filter 8th order is designed. The fitness function problem is discussed based on values of the ripple of the passband, a ripple of the stopband, and a transition band. Thus, the proposed algorithm results are compared with previous studies results. From results comparison, results have shown the convergence rate with the DS-PSO algorithm outperformed the convergence rates using fuzzy gravitational search algorithm (FGSA), gravitational search algorithm (GSA), and differential evolution (DE) with mean values of 55.21%, 57.80%, and 70.40%, respectively. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

The paper presents a precisely engineered ontology that serves as the main knowledge base for the definition and semantic registration for the entities within the IoT perimeter to facilitate their automated deployment.

The increasing incidence of WB over the last several years indicates a need for improved prediction or early diagnosis. We hypothesized that the use of body fluids, including blood, may be more suitable than breast muscle tissue in developing a minimally invasive diagnostic tool for WB detection. To identify potential early-age-biomarkers that may represent the potential onset of WB, blood samples were collected from 100, 4 wks old commercial male broilers. At 8 wks of age, WB conditions were scored by manual palpation. A total of 32 blood plasma samples (eight for each group of WB and non-WB control birds at two time points, 4 wks and 8 wks) were subjected to shotgun proteomics and untargeted metabolomics to identify differentially abundant plasma proteins and metabolites in WB broilers compared to non-WB control (Con) broilers. From the proteomics assay, 25 and 16 plasma proteins were differentially abundant (p < 0.05) in the 4 and 8 wks old samples, respectively, in WB compared with Con broilers. Of those, FRA10A associated CGG repeat 1 (FRAG10AC1) showed >2-fold higher abundance in WB compared with controls. In the 8 wks old broilers, 4 and 12 plasma proteins displayed higher and lower abundances, respectively, in WB compared with controls. Myosin heavy chain 9 (MYH9) and lipopolysaccharide binding protein (LBP) showed more than 2-fold higher abundances in WB compared with controls, while transferrin (TF) and complement C1s (C1S) showed more than 2-fold lower abundances compared with controls. From the untargeted metabolomics assay, 33 and 19 plasma metabolites were differentially abundant in birds at 4 and 8 wks of age, respectively, in WB compared with controls. In 4 wks old broilers, plasma 3-hydroxybutyric acid (3-HB) and raffinose concentrations showed the highest and lowest fold changes, respectively, in WB compared with controls. The blood plasma 3-HB and raffinose concentrations were confirmed with targeted biochemical assays. Blood biomarkers, such as 3-HB and raffinose, may be suitable candidate targets in the prediction of WB onset at early ages. © Copyright © 2021 Kong, Khatri, Kang, Shouse, Kadhim, Kidd, Lassiter, Hiltz, Mallmann, Orlowski, Anthony, Bottje, Kuenzel and Owens. | Frontiers Media S.A. | 1664042X | |

They serve as cellular anchor, allowing cells to stay attached to the extracellular matrix (ECM), and can also regulate cellular transduction. Previously, it has been suggested that vesicles such as endosomes could interact directly with FA or be implicated in their turnover. In this study, we investigated whether there is a relationship between FA and the early endocytic machinery in MDA-MB-231 cells. Methods: In this study, cell culture, transfection, time laps confocal microscopies, immunocytochemistry, western blotting, Cell fractionation and immunoprecipitation techniques were performed. Results: Cells acutely treated with Dynasore, an inhibitor of dynamin, or with Pitstop 2, an inhibitor of clathryn-dependent endocytosis showed a reduction in the expression of early endosome biomarkers such as Rab5 and EEA1. Additionally, cells treated with these endocytic inhibitors exhibited an increase number and size of FA, as well as an increase FA turnover duration. This data was consistent with the reduction of the speed of cell migration. We demonstrated that Rab5- and EEA1-positive early endosomes were found to be colocalized with internalized FA. Conclusions: The present study suggests that there is a link between FA and early endosome markers, which indicates that the early endosomes may be involved in FA dynamics. © 2021, Reports of Biochemistry and Molecular Biology, All Rights Reserved. | Varastegan Institute for Medical Sciences | 23223480 | |

The study was achieved by measurement of air and water temperature, pH, and salinity, as well as the measurement of the concentration of some heavy elements (Cd, Pb, Ni, and Cu) in both dissolved and particulate phases in water and an exchangeable and residual phase in sediments and the tissues of two aquatic plants species, Ceratophyllum demersum L. and Phragmatis australis (Can.). The mean concentrations of the heavy elements (Cd, Pb, Ni, and Cu) in the dissolved phase in water were (0.07, 1.19, 3.17, and 0.03μg/l) respectively, while their concentration in the particulate phase was (15.73, 24.71, 65.63 and 22.86 μg/g) respectively. The mean concentrations of the heavy metals in sediments in an exchangeable phase were 15.73, 24.71, 65.63, and 22.86 (μg/g), respectively, while in the residual phase were 0.07, 0.85, 74.62, and 14.00 (μg/g) respectively. Results confirmed increased mean concentrations of heavy metals in aquatic plants tissues compared to their means in water. The maximum mean of heavy metals was recorded in Ceratophyllum demersum L.

Naturally, users have diverse opinions, and only trusting user ratings of products may produce inaccurate recom-mendations. Therefore, it is essential to offer a new similarity measure that enhances recommendation accuracy, even for customers who only leave a few ratings. Thus, this article proposes an algorithm for user similarity measures that exploit item genre information to make more accurate rec-ommendations. This algorithm measures the relationship between users using item genre infor-mation, discovers the active user’s nearest neighbors in each genre, and finds the final nearest neighbors list who can share with them the same preference in a genre. Finally, it predicts the active-user rating of items using a definite prediction procedure. To measure the accuracy, we propose new evaluation criteria: the rating level and reliability among users, according to rating level. We implement the proposed method on real datasets. The empirical results clarify that the proposed algorithm produces a predicted rating accuracy, rating level, and reliability between users, which are better than many existing collaborative filtering algorithms. © 2021 by the authors.

Hydrogen peroxide was the oxygen source. All the experiments were carried out at 25 MPa and a range of temperatures from 425-525 ºC. The residence times range from 6 s to 14 s. Results were presented in terms of total organic carbon (TOC) as a function of time with various process parameters. The findings support the positive effect that propylene glycol has on the destruction of 3-methylpyridine, where TOC removal is ≥ 97.5% at 525 ºC and 14 s. The maximum TOC removal efficiency is 93% at 425 ºC, 14 s, and the [propylene glycol]/[3-methylpyridine]o ratio of 3. The removal efficiency of nitrogen in the presence of propylene glycol reaches 89% at 525 ºC and 10 s. The oxidant ratio also has a positive effect on the removal of TOC in the three systems. Addition of propylene glycol causes a significant development in the ratio at 425 ºC, more so than when isopropyl alcohol was added. This is due to two hydroxyl groups in propylene glycol oxidation that enhance the reaction by generating various free radicals. © 2021 Chemical Publishing Co..

The purpose of this study is to synthesize PO coated iron oxide magnetic nanoparticles (Fe3O4@PO NPs) and their anti-leishmanial effects in vitro and in vivo against cutaneous leishmaniasis. Methods: Fe3O4 magnetic nanoparticles were synthesized by the coprecipitation of Fe2 + and Fe3 + ions and used as a nanocarrier for the production of Fe3O4@PO NPs. The in vitro antileishmanial effects of PO-coated Fe3O4 NPs and Fe3O4 NPs (10–200 µg/mL) was determined against the intracellular amastigotes of Leishmania major (MRHO/IR/75/ER) and, then, examined on cutaneous leishmaniasis induced in male BALB/c mice by L. major. The rate of infectivity, production of nitric oxide (NO), and cytotoxic activates of Fe3O4 NPs and Fe3O4@PO NPs on J774-A1 macrophage cells were determined. Results: The size scattering of the Fe3O4 NPs and Fe3O4@PO NPs were in the range among 1–40 and 5–55 nm, respectively. The obtained IC50 values were 62.3 ± 2.15 μg/mL, 31.3 ± 2.26 μg/mL, and 52.6 ± 2.15 μg/mL for the Fe3O4 NPs and Fe3O4@PO NPs, and MA, respectively. The results revealed that the mean number of parasites and the mean diameter of the lesions was considerably (p < 0.05) decreased in the infected mice treated with Fe3O4 NPs and Fe3O4@PO NPs. The Fe3O4 NPs and Fe3O4@PO NPs significantly (p < 0.05) prompted the production of NO as a dose-dependent manner. The promastigotes pre-incubated in Fe3O4 NPs and Fe3O4@PO NPs at the concentration of 5 µg/mL had the ability to infect only 41.7% and 28.3% of the macrophages cells. The selectivity index of greater than 10 for Fe3O4 NPs and Fe3O4@PO NPs showed its safety to the J774-A1 macrophage cells and specificity to the parasite. Conclusion: The results of this survey indicated the high potency of Fe3O4@PO NPs to inhibit the growth of amastigote forms of L. major as well as recovery and improvement CL induced by L. major in BALB/c mice without significant cytotoxicity. The results also indicated that, although the possible anti-leishmanial mechanisms of Fe3O4@PO NPs have not been clearly understood, however, the triggering of NO may be considered as one of the possible anti-leishmanial mechanisms of these nanoparticles. However, additional studies, in particular in clinical contexts, are mandatory. © 2021 The Authors | Elsevier Masson s.r.l. | 7533322 | |

Some parts which lose their dimensional tolerance during use need repair and refurbishment when replacement is avoidable at a high cost. Due to oscillatory vibration action, the compressor blades' dovetail roots are subject to fatigue. The compressor case comes into contact with rotating blades, causing blade damage due to a misalignment shaft, case ovality, or inadequate clearance. Using various contact surfaces undergoing spinning and joint movement takes place during the operation of the turbine. Rotating and stationary parts in the hot sector need a higher working temperature thermal insulation, enhancing the turbine's thermodynamic performance. The application of various coatings that protect the components from failure meets this broad range of functional motor requirements. In terms of not seeking a more in-depth perspective into the field of steam turbine coating, the present review describes the specifics of these coatings at a single stage, application and characterization approaches, and indicative potential directions that are useful to an industrial engineer. © 2021 Zibeline International Publishing Sdn.

Ten samples were collected, where five samples from both sand dunes, and valley sediments. Grain size analysis revealed that sand, silt and clay fractions are the constituents of these sediments. Sand fractions predominant in the dunes and the texture is classified as silty sand, whereas clay fractions dominate in the valley sediments, with sandy clay texture. The mineralogy is determined by X-ray diffraction, which revealed that quartz is the main mineral in both study areas, followed by calcite, feldspars in lesser amount and evaporates (gypsum) in minor component of the light minerals. Petrographically, monocrystalline quartz dominates over polycrystalline quartz in both areas. Rock fragments in the valley sediments are higher than in the sand dunes, which are comprised of carbonate, chert, igneous, metamorphic, evaporate, and mudstone rock fragments. Feldspars are approximately similar in the study areas and comprised mainly alkali feldspar (potash feldspar) and plagioclase. Petrogenically, the sand dunes occupy the quartzose-recycled field, while the valley sediments fall in transitional recycled fields represented recycled orogeny. © 2021, Union of Iraqi Geoogists.

Focal adhesions (FA) are local regions of plasma membrane consisting of multiprotein complexes providing adhesive contact between the cell and the extracellular matrix (ECM). FA turnover regulates different signalling pathways implicated in various cellular responses (e.g. cell migration). Endocytosis, specifically the dynamin and clathrin pathways, is known to regulate cell migration by modulating FA dynamics. In this study, we investigated whether NO activity regulates cell migration, FA dynamics and early endosome trafficking in MDA-MB-231 cells. The assessment of cell migration showed a slowing down of cell migration and an increased duration of FA turnover in cells treated with inhibitors of NO synthase (NOS) such as L-NAME or 1400W. In addition, these treatments were found to exhibit no effect on transferrin and dextran uptake mediated by endocytosis and micropinocytosis, respectively. The number of early endosome antigen 1 (EEA1)-positive endosomes was reduced while their sizes were found to increase in cells treated with L-NAME or 1400W. In contrast, these inhibitors did not affect the number nor the size of Rab5-positive endosomes. Furthermore, we demonstrated that EEA1, endothelial NO synthase (eNOS) and inducible NO synthase (iNOS) were colocalised. Using the biotin switch assay followed by western blot, we showed that early endosome proteins such as APPL1, EEA1, Rab5 were found to be S-nitrosylated. These results were further supported by the sequence analysis performed with the GPS-SNO algorithm which predicted the S-nitrosylation of these endosomal proteins. Taken together, our findings suggest that NO might be involved in cell migration and FA turnover through early endosome trafficking in MDA-MB-231 cells.

The target of the current study is to propose and investigate a novel seasonal combined cycle driven by a biogas-fueled gas turbine from thermodynamic and economic viewpoints. Regarding the high-temperature of the turbine's exhaust gases, an integration of Rankine and ejector refrigeration cycles is configured. The bottoming cycle is designated for winter and summer conditions, independently. Hence, a combined cycle capable of operating as a cogeneration system producing electricity/heating or electricity/cooling, individually, is designed. Moreover, a parametric study based on assessing the impact of key parameters on the essential variables and a multi-criteria optimization trough a genetic algorithm are performed to attain the facilities of the proposal. According to the results, the capability of the whole system in winter conditions is significantly higher than that for summer conditions due to the higher heating capacity. Also, the evaluated variables are more affected by change in the environment temperature in both seasons. Additionally, the optimal overall energy, exergy and levilized cost of products are calculated as 79.2%%, 45.6%, and 21.7 $/GJ for summer and 70.7%, 37.0%, and 17.6 $/GJ for winter, respectively. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

The strain energy released when a fatigue crack advances has the effect of exciting acoustic waves, which travel through the structures and are picked up by the sensors. Piezoelectric wafer active sensors (PWAS) can effectively sense acoustic waves due to fatigue-crack growth. Conventional acoustic-wave passive SHM, which relies on counting the number of acoustic events, cannot precisely estimate the crack length. In the present research, a novel method for estimating the crack length was proposed based on the high-frequency resonances excited in the crack by the energy released when a crack advances. In this method, a PWAS sensor was used to sense the acoustic wave signal and predict the length of the crack that generated the acoustic event. First, FEM analysis was undertaken of acoustic waves generated due to a fatigue-crack growth event on an aluminum-2024 plate. The FEM analysis was used to predict the wave propagation pattern and the acoustic signal received by the PWAS mounted at a distance of 25 mm from the crack. The analysis was carried out for crack lengths of 4 and 8 mm. The presence of the crack produced scattering of the waves generated at the crack tip; this phenomenon was observable in the wave propagation pattern and in the acoustic signals recorded at the PWAS. A study of the signal frequency spectrum revealed peaks and valleys in the spectrum that changed in frequency and amplitude as the crack length was changed from 4 to 8 mm. The number of peaks and valleys was observed to increase as the crack length increased. We suggest this peak–valley pattern in the signal frequency spectrum can be used to determine the crack length from the acoustic signal alone. An experimental investigation was performed to record the acoustic signals in crack lengths of 4 and 8 mm, and the results were found to match well with the FEM predictions. © 2021 by the authors.

In this study, Au-doped tin oxide/carbon quantum dots (Au:SnO2/carbon quantum dots) nanocomposites was prepared via simple and friendly to the environment route. The obtained results from X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) analysis, photoluminescence spectroscopy (PL), and Ultra violet-Visible (UV-Vis) spectroscopy showed the formation of the pure and regular shape of Au:SnO2/ carbon quantum dots. Then, prepared Au:SnO2/ carbon quantum dots was utilized for the testing of antibacterial activity using Aspergillus niger,, Bacillus subtilis, Candida albicans, Escherichia coli, Klebsiella pneumonia, pseudomonas aeruginosa, Salmonella paratyphi-A serotype, Shigella dysenteriae, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. The modified sample showed significant improvement against tested bacteria. The best antibacterial activity was observed in Au:SnO2/ carbon quantum dots against pseudomonas aeruginosa with MIC values of 62.5 μg/ml. The obtained results demonstrate Au:SnO2/ carbon quantum dots nanocomposites are highly suitable as an antibacterial agent against both Gram-negative and Gram-positive bacteria. © This work is licensed under the Creative Commons Attribution 4.0 International License. | University of Kashan | 22517871 | |

Products of wide use are selected and employed in the current study. Six types of cosmetic products of different origins are tested by taking equivalent quantities of these products and putting them in plastic boxes. The detector is left with the samples for a period of 50 days. In addition to measuring the rate of surface evaporation of radon gas, measurements of the annual equivalent dose of radon gas are also carried out. The results show that the highest concentration of radon gas is in Charcoal Facial SCRuB (American origin) and it is equal to 0.0795 Bq/m3, whereas the lowest one in "bb" cream basis (5 in 1) is equal to 0.0355 Bq/m3. Based on specific international organizations and agencies, the concentration of radon in the samples under consideration is within the acceptable limits. © 2021 Lavoisier.

Several ways have been discussed in which these resources could be invested by means of development projects for economic benefit, which represent a step towards the development of arid and semi-arid regions in Iraq, particularly in its southern deserts. The research showed that the basin is characterized by the existence of a proper water drainage network, thereby providing a sufficient amount of water to be invested in agriculture, in addition to the available groundwater reservoirs. The availability of such fertile soil leads to the growth of a wide range of natural vegetation, enabling large areas of the basin to be invested for grazing purposes.

The name of my daughter "Noor" has been given to this curve; therefore, Noor term describes this curve whenever it is used in this paper. This curve is a form of these opened curves as it extends in the infinity along both sides from the origin point. The curve is designed by a circle/ ellipse which are drawing curvatures that tangent at the origin point, where its circumference is passed through the (0,2a). By sharing two vertical lined points of both the circle diameter and the major axis of the ellipse, the parametric equation is derived. In this paper, a set of various cases of Noor curve are graphically studied by two curvature cases; a circle and an ellipse, and all figures and obtained rigour measurements are checked by AutoCAD program. With its simple, symmetric form, the future predictions are tuned for the Noor's curve to be usefully engaged in important practical applications. © 2021 University of Baghdad.

It was shown that the sizes and concentrations of scattering centers greatly affect the optical amplification mechanism, thresholds, narrowing the emission intensity and then the transition from the incoherent to a coherent type of random laser. The emergence of spikes and the increase in their number are also discussed under the influence of the size and concentration of silver (Ag) nanowires.

This work was undertaken with the concrete damaged plasticity model (CDP). The expansion of corrosion product was utilized to represent the steel-concrete boundary to study the behavior of SFRC beams. Three beams with three volume fractions of steel fiber (0.8 %, 1.2 %, and 1.8 %) and three reinforced concrete (RC) beams with and without stirrups were created and tested under four-point loading to assess the shear capacity of beams. Corrosion of rebars at one of the RC beams that does not contain shear reinforcements will be studied. The crack patterns and load deflections of these beams were compared with experimental results found by the authors. The conclusions of this analysis will be valuable in considering the structural behavior of SFRC structures with uniform steel bar corrosion using FEM. Analytical results showed that the suggested model is qualified in better simulation and in accuracy of numerical and experimental results. The differences between analytical and experimental results were less than 8 % for load carrying capacity and 14 % for deflection; these differences are also satisfactory within the limits of the engineering conclusion. © 2021 Faten Y.

Any untrusted node can eavesdrop on the medium, listen to transmissions and obtain sensitive information within the wireless network. In this paper, we propose a new mechanism which combines the advantages of two techniques namely iJam and OFDM phase encryption. Our modified mechanism makes iJam more bandwidth efficient by using Alamouti scheme to take advantage of the repetition inherent in its implementation. The adversary model is extended to the active adversary case, which has not been done in the original work of iJam and OFDM phase encryption. We propose, through a max min optimization model, a framework that maximizes the secrecy rate by means of a friendly jammer. We formulate a Zero-Sum game that captures the strategic decision making between the transmitter receiver pair and the adversary. We apply the fictitious play (FP) algorithm to reach the Nash equilibria (NE) of the game. Our simulation results show a significant improvement in terms of the ability of the eavesdropper to benefit from the received information over the traditional schemes, i.e. iJam or OFDM phase encryption. © 2021 Institute of Advanced Engineering and Science.

UEC often splits the network, reduces network life, and leads to performance degradation. Sometimes, improving energy consumption is more complicated because it does not reduce energy consumption only, but it also extends network life. This makes energy consumption balancing critical to WSN design calling for energy-efficient routing protocols that increase network life. Some energy-saving protocols have been applied to make the energy consumption among all nodes inside the network equilibrate in the expectancy and end power in almost all nodes simultaneously. This work has suggested a protocol of energy-saving routing named spider monkey optimization routing protocol (SMORP), which aims to probe the issue of network life in WSNs. The proposed protocol reduces excessive routing messages that may lead to the wastage of significant energy by recycling frequent information from the source node into the sink. This routing protocol can choose the optimal routing path. That is the preferable node can be chosen from nodes of the candidate in the sending ways by preferring the energy of maximum residual, the minimum traffic load, and the least distance to the sink. Simulation results have proved the effectiveness of the proposed protocol in terms of decreasing end-to-end delay, reducing energy consumption compared to well-known routing protocols. © 2021 Institute of Advanced Engineering and Science.

It has been used as a recreation agent, for relaxation, as well as for pain relief. However, hepatotoxicity is a widespread problem associated with medicines in general. Most herbal supplements are metabolized by the liver, and thus the liver represents the target organ. At present, Yangonin toxicity appears to be "idiosyncratic". Therefore, a study was designed in order to investigate the organelle-based changes in hepatocytes, after treatment with Yangonin alone and in combination with EtOH. Thirty rats were divided into five groups comprising of six animals each. The groups comprised of the control groups {(NCx) & (PCx)}, Yangonin (Ya) group, ethanol (EtOH) group, and the combination of (Ya) and ethanol (EtOH+Ya) group. The experiment was conducted over a period of 14 weeks, as a sub-chronic study. At the end of the 14 th week, mitochondria, peroxisome, rough and smooth endoplasmic reticulum, and nuclei of hepatocytes, were evaluated using a scoring system. The results were compared with histopathological findings, as well. Treatment with Ya significantly induced hepatotoxic scores as compared to the control groups. Organelle injury scores increased significantly with Ya treatment, while rats that received "EtOH+Ya"showed the severest lesions of liver scores such as, severe hepatocellular degeneration, necrosis, and hypertrophy. Ultrastructural and histopathological scores in both groups were in very strong correlation (r = 0.928 for EtOH, r = 0.921 for Ya alone and r = 0.903 for Ya plus EtOH group). In conclusion, ethanol enhanced the sedative and hypnotic activity of Ya, and markedly increased toxicity. Findings based on TEM examination of organelles, supported the histological results as well as tissue lesions/injuries in hepatocytes, a result of hepatotoxin-induced hepatopathy. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

The study showed an increase in bending loss with decreases bending radius, decreases core radius and increases wavelength. The graded order is effective up to after which the loss is constant. There is an oscillating change in loss caused by interference between the outgoing and reflected waves from the boundaries, which becomes clearer as the loss itself increases. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

The usage of this technology was informed by the need to have the laser spot's highest energy positioned precisely, eventually allowing for the facilitation of further product work piece joining. Indeed, the joining occurred in laser welding machinery. Relative to the displacement phase, it is notable that it could aid in work piece placement into superposition areas, upon which there could be the joining of the parts. Training programs or models that were used involved convolutional neural network and deep learning, which allowed for the resultant system's enhancement of the accuracy with which the positioning could be achieved. Also, the aforementioned algorithms were insightful because they led to the enhancement of machine work efficiency. Similarly, in the study, there was the proposing of a bi-analytic deep learning localization technique. For the purpose of system monitoring in real time, there was the use of a camera. As such, the initial stage entailed the application of the convolutional neural network, which aided in the implementation of large-scale initial searchers before having the laser light spot zone located. In turn, the phase that followed entailed increasing the camera's optical magnification, which paved the way for the spot area's re-imaging, as well as the application of a template matching method to ensure that high-precision repositioning was achieved. When the parameter of the search result area's ratio was considered, it could be seen that the study was able to determine the target spot's integrity parameters. For the case of the complete laser spot, there was the performance of the centroid calculation. Also, in situations where an incomplete laser spot reflected the target, there was the performance of invariant moments' operation. From the findings, the study indicated that from incomplete laser spot images, the laser spot's highest energy could be positioned precisely. The study also established that in order to establish the displacement amount, the image's center and the laser spot's highest energy could be overlapped. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

Noise reduction is an essential process of image processing in order to improve, analyze and interpret important information in an image. Edges are important to the visual appearance of images, to preserve important features such as edges and corners during the noise reduction process. A class of fourth- and second-order partial differential equations (PDEs) are used to optimize the trade-off between noise removal and edge preservation. Image quality assessment plays an important role in various image processing applications. It is still an active field of research. Several techniques have been suggested for measuring image quality but none of them are ideal for measuring the quality. This paper presents a new assessment of image quality based on topological data analysis (TDA) which is used for evaluating noise removal from colour images and also for assessing the performance of PDE-based denoising models. The experimental results show that the proposed assessment model gives high correlation. Furthermore, the proposed method provides very low computational load and similar extraction of characteristics to human perceptional assessment. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

Electroencephalogram (EEG) is one of the commonly used devices for seizure recognition and epilepsy detection. Recognition of convulsions using EEG waves takes a relatively long time because it is conducted physically by epileptologists. The EEG signals are analyzed and categorized, after being captured, into two types, which are normal or abnormal (indicating an epileptic seizure). This study relies on EEG signals which are provided by Arrhythmia Database. Thus, this work is a step beyond the traditional database mission of delivering users’ inquiries; instead, this work is to extract insight and knowledge of such data. The features are extracted from the signals by applying the Discrete Wavelet transform (DWT) method on the input EEG signals. Two different algorithms Support vector machine (SVM) and k-nearest neighbours (KNN) are applied to the extracted features. After using the above method, two different types of EEG are expected by using classification, either to be normal (refers to the normal activeness of the brain) or abnormal (refers to the non-normal activeness of the brain, which may involve epilepsy). The evaluation is based on three parameters (Precision, Recall, and Accuracy), and also on the implementation time. In this research, two different methods are used, the first is the DWT with SVM, and the second is the DWT with KNN. With regard to the three-parameter values and implementation time, it turned out that the second method was more efficient than the first because of its higher accuracy. © 2021 University of Baghdad-College of Science.

Solubility study of a drug is one of the contributing factors of its oral bioavailability. The formulation of poorly soluble drugs for oral delivery presents a challenge to the formulatio n technologists. Methods: The present study has shown that it is possible to raise the solubility for poorly soluble drugs like famotidine, by preparing solid dispersion using natural water-soluble polymer (xyloglucan and hyaluronic acid) as solubilizer through solvent evaporation method. Physical mixture and solid dispersion of famotidine with xyloglucan (XG) or hyaluronic acid in a ratio of 1:1, 1:2, 1:3 were prepared. Solubility study, drug content, dissolution profile and compatibility study were performed for famotidine in solid dispersions XS1, XS2, XS3, HS4, HS5, HS6 as well as in physical mixtures at a ratio 1:1 for both polymer (XG and hyaluronic acid). Results: It was observed that solid dispersions of each drugs showed an increase in dissolution rate in comparison with its pure drug in the ratio of 1:1 (Drug: carrier). It can be concluded that with the care and proper use of xyloglucan, the solubility of drugs poorly soluble can be improved. The prepared solid dispersion showed improvement of drug solubility in all prepared formulas. The best result was obtained with formula XS1 (famotidine: xyloglucan at ratio 1:1) that showed 26 fold increase in solubility compared to the solubility of pure drug. Conclusion: The natural solid dispersion, increased wettability and reduced crystallinity of the drug which leads to improving solubility and dissolution. © 2021 The Authors.

The electronic properties of the anticancer drugs/ZnONS studied by using DFT method, which implemented in the quantum espresso package. Our finding shown that ZnONS has a semiconductor behavior. Interestingly, the electronic band gap of the 5-FU/ZnONS and GB/ZnONS is decreased, but they still have semiconductor behaviors. For 6-MP/ZnONS, it is increased and converted to n-type semiconductor for CP/ZnONS structure. According to acquired findings, the complex structures became more stable and lower reactive due to the total energy of these complex structures is increased compared to pristine ZnONS. All complex structures are required higher excitation energy to transfer an electron due to the chemical hardness of all complex structures is decreased, but the 6-MP/ZnONS structure has the opposite behavior. There is a weak interaction between ZnONS and (5-FU, 6-MP, and GB) and good interaction between the ZnONS and CP due to the electrophilic of these structures has lower and higher values, respectively. Concisely, ZnONS considered the greatest substrate to carry all these anticancer drugs. © 2021 Elsevier B.V. | Elsevier B.V. | 13877003 | |

Proteins extracted from bran (WBPC) have potential to improve the protein content and protein quality of pasta, but their contribution to the phytochemical content of pasta is unknown. Findings: In this study, WBPC was added to a spaghetti formulae at 0, 1%, 5%, 10%, and 20% (w/w). The dried uncooked spaghetti were characterized for quali-quantitative composition of phytosterols and phenolic acids. Also, both the uncooked and cooked samples were evaluated for total soluble phenolics (TSP) and antioxidant activity (AO). Results showed that pasta with 20%WBPC increased total phytosterol content (~55%), and phenolic acids content (~57%), with ferulic acid being the main component. Cooked spaghetti had reduced TSP and AO compared to the uncooked. However, cooked 20%WBPC spaghetti had significantly higher contents of both TSP (~37%) and AO (~93%) compared to 100% durum semolina spaghetti. The in vitro starch digestion of pasta was not affected by WBPC at these levels. Conclusion: Spaghetti enriched with WBPC has improved phytochemical content without negative changes on pasta in vitro starch digestion. Significance and novelty: WBPC is a suitable ingredient to enhance the phytochemical content of regular spaghetti with potential health benefits. © 2021 Cereals & Grains Association | John Wiley and Sons Inc | 90352 | |

In this study, the theory of total quality management (TQM) is used to identify the quality shortcomings of public service projects in Iraq. Accordingly, data derived from 55 online completed surveys were used to assess the TQM of public service construction. The elements of TQM that were assessed are leadership, communication and cooperation, workforce management, process management, continuous improvement, and client satisfaction. The collected data were analyzed utilizing standardized scores to measure the relative shortcoming of TQM's variables. The results show that, in general, Iraqi engineers perceived the existence of citizens' satisfaction as being relatively higher than other elements. Furthermore, the results suggest that several key performance indicators (KPIs) scored relatively lower than others. Thus, the study highlights where improvements are needed most for TQM of public service projects in Iraq. In addition, there is a lack of quantitative research that supports TQM benefits within the construction context. Therefore, this study contributes to the body of knowledge regarding the usability of TQM within the construction industry. © 2020 American Society of Civil Engineers. | American Society of Civil Engineers (ASCE) | 10840680 | |

The Rus Formation has been described and its basin was analyzed separately because it was deposited during the regression period (Middle Eocene), which is a transitional period between these two cycles. This study includes analysis of the geohistory of this succession, interpretation of the changes of the accumulation, and calculation of subsidence rates. The results were compared with the space available to explain the basin development. The study site included the boreholes of Garraf-84 and 92, Halfaya-1, Nasirya-13 and 40, and Noor-5 at the Mesopotamian Block, in addition to the Ratawi-8, Tuba-15, Rumaila-217, Zubair-45, and West Qurna-60 at the Basra Block. The Aliji basin was characterized by the decrease in accommodation values to the northeast direction and the increase in all the other parts of the study area. A comparison of the setting of this basin with the Umm Er Radhuma basin gives a clear evidence of the tectonic impact coming from the northeast. During the Middle Eocene stage, we notice that the basin was affected by comprehensive uplifting processes. This led to the generation of a very shallow basin (Rus basin) with the exposure of the northern part of the basin during the regression stage. The Middle-Late Eocene basin is represented by a transgression stage with high subsidence, where the sea level had been raised and covered the northeastern and eastern parts of the studied area by deep sea deposits (Jaddala Formation). While the other parts of the study area were characterized by shallow sediments of Dammam Formation. This period ended with a clear tectonic uplift occurring in the northeastern parts and decreasing towards the southwest. This confirms the reactivation of the tectonic action from the northeast, represented by the continental collision. All these sources of evidence indicate that the study area is divided into a northern part and a southern part. Both of these parts are separated by a major tectonic lineament extending from the West Qurna oil field to the Nasiriya oil field, which confirms the presence of the tectonic boundary between the Mesopotamian block and the Basra block. In addition, there exists a secondary tectonic boundary that divides the Mesopotamian block into two parts, the first is to the east and the other is to the west. The results showed that the eastern side was most affected by the collision of the Iranian Plate with the Arabian Plate, which led to its uplift, while the western side was less affected by this tectonics evidence. © 2021 University of Baghdad-College of Science.

Renewable energy driven Triple Combined Cycle (TCC) is a relatively new idea in this respect. In this paper, a biomass gasification-fueled TCC is presented in which the conventional gas turbine, as the topping cycle, is combined with a Closed Brayton Cycle (CBC) and an Organic Rankine Cycle (ORC). The proposed TCC is integrated with LNG regasification process to exploit its cold exergy for compressor inlet cooling of the CBC. For the CBC three working fluids (namely: helium, nitrogen and carbon dioxide) are considered. There is a good thermal match between the LNG and these fluids in heat rejection process and they can be cooled down to temperatures of below 0°C at the compressor inlet for net power augmentation. Thermoeconomic method is applied to evaluate the TCC performance and optimization using genetic algorithm is employed to minimize the Levelized Cost of Electricity (LCOE). In the economic analysis the cost rate of environmental impacts due to pollutant emissions is also considered. The results indicated the superiority of helium over the other investigated working fluids from the economic perspective for which the LCOE is found to be 51.38 $/MWh. However, as an interesting outcome it is found that, from thermodynamic standpoint using CO2 as the working fluid yields higher exergy efficiency by 6.7% than the helium. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

This is due to space weather impacts on both space-borne and ground-based systems, and industries, which subsequently impacts our lives. In the current study, the deep learning approach is used to establish an automated hybrid computer system for a short-term forecast; it is achieved by using the complexity level of the sunspot group on SDO/HMI Intensitygram images. Furthermore, this suggested system can generate the forecast for solar flare occurrences within the following 24 h. The input data for the proposed system are SDO/HMI full-disk Intensitygram images and SDO/HMI full-disk magnetogram images. System outputs are the “Flare or Non-Flare” of daily flare occurrences (C, M, and X classes). This system integrates an image processing system to automatically detect sunspot groups on SDO/HMI Intensitygram images using active-region data extracted from SDO/HMI magnetogram images (presented by Colak and Qahwaji, 2008) and deep learning to generate these forecasts. Our deep learning-based system is designed to analyze sunspot groups on the solar disk to predict whether this sunspot group is capable of releasing a significant flare or not. Our system introduced in this work is called ASAP_Deep. The deep learning model used in our system is based on the integration of the Convolutional Neural Network (CNN) and Softmax classifier to extract special features from the sunspot group images detected from SDO/HMI (Intensitygram and magnetogram) images. Furthermore, a CNN training scheme based on the integration of a back-propagation algorithm and a mini-batch AdaGrad optimization method is suggested for weight updates and to modify learning rates, respectively. The images of the sunspot regions are cropped automatically by the imaging system and processed using deep learning rules to provide near real-time predictions. The major results of this study are as follows. Firstly, the ASAP_Deep system builds on the ASAP system introduced in Colak and Qahwaji (2009) but improves the system with an updated deep learning-based prediction capability. Secondly, we successfully apply CNN to the sunspot group image without any pre-processing or feature extraction. Thirdly, our system results are considerably better, especially for the false alarm ratio (FAR); this reduces the losses resulting from the protection measures applied by companies. Also, the proposed system achieves a relatively high scores for True Skill Statistics (TSS) and Heidke Skill Score (HSS). © 2021 COSPAR | Elsevier Ltd | 2731177 | |

In this work, an innovative triple combined power cycle driven by hybrid biomass-solar energies is proposed, analyzed and optimized from the exergy, economics, and environmental standpoints. In order to fulfill the intermittent nature of solar energy, it is used for hydrogen production (via Proton Exchange Membrane (PEM) electrolyzer supplied by electricity from Photovoltaic-Thermal (PVT) panels) which is injected into a post-firing combustion chamber of the gas turbine. The proposed system consists of a biomass fueled gas turbine combined with a closed Brayton cycle and a Rankine cycle as the bottoming cycles. To examine the system performance, thermoeconomic evaluation is carried out and multi-objective optimization is performed to find the optimum operating conditions based on Levelized Cost Of Electricity (LCOE) and CO2 emission. The results revealed that, incorporation of solar-based hydrogen production with the biomass-based gas turbine results in a significant decrease in CO2 emissions and biomass consumption as well as increase in power generation capacity. However, it brings about a decrease of exergetic efficiency (due to the large exergy destruction in PVT and PEM electrolyzer) and an increase of LCOE (due to the additional expenditures imposed by PVT panels and PEM electrolyzer). Under the best operating conditions based on multi-objective optimization, the proposed triple combined cycle attains exergy efficiency of 30.44% with a LCOE of 61.37 $/MWh, and CO2 emission of 0.4579 kg/kWh. © 2021 Elsevier Ltd | Elsevier Ltd | 1968904 | |

This paper creates and assesses a satisfactory model of the trip distribution stage for the Nasiriyah city by using two models, Gravity and Fratar methods. A large sample was used for developing the model. The research methodology depends on discussing the theoretical fundamentals of the various methods for estimating the trips distribution and examining the suitability of these fundamentals for the conditions of the selected study area. Two different models had been used, namely; Frater and Gravity model. These models were calibrated using real data. The study tests the accuracy of the models, including overall statistical assessments of the predicted movements. Finally, the study recommended to use Fratar Method. These results had been confirmed to the literature that, if the area is a homogenous growth, the best model is the growth factor (Fratar's method) and if the area is experiencing rapid changes. The gravity model will produce satisfactory results because it takes into account the competition in different land uses. © 2021.

Aim: The present study aims to evaluate in vitro and in vivo antileishmanial effects of copper nanoparticles (CuNPs) green synthesized by Capparis spinosa fruit extract alone and combined with meglumine antimoniate (MA). Methods: CuNPs were green synthesized by C. spinosa methanolic extract. The in vitro antileishma-nial activity of CuNPs (10–200 µg/mL) or MA alone (10–200 µg/mL), and various concentrations of MA (10–200 µg/mL) along with 20 µg/mL of CuNPs, was assessed against the Leishmania major (MRHO/IR/75/ER) amastigote forms and, then tested on cutaneous leishmaniasis induced in male BALB/c mice by L. major. Moreover, infectivity rate, nitric oxide (NO) production, and cytotoxic effects of CuNPs on J774-A1 cells were evaluated. Results: Scanning electron microscopy showed that the particle size of CuNPs was 17 to 41 nm. The results demonstrated that CuNPs, especially combined with MA, significantly (p < 0.001) inhibited the growth rate of L. major amastigotes and triggered the production of NO (p < 0.05) in a dose-dependent manner. CuNPs also had no significant cytotoxicity in J774 cells. The mean number of parasites was significantly (p < 0.05) reduced in the infected mice treated with CuNPs, especially combined with MA in a dose-dependent response. The mean diameter of the lesions decreased by 43 and 58 mm after the treatment with concentrations of 100 and 200 mg/mL of CuNPs, respectively. Conclusion: The findings of the present study demonstrated the high potency and synergistic effect of CuNPs alone and combined with MA in inhibiting the growth of amastigote forms of L. major, as well as recovery and improving cutaneous leishmaniasis (CL) induced by L. major in BALB/c mice.

Using the density matrix theory, the amplitude and phase of the transmission function are studied. It is shown that the transmission is enhanced by the presence of SGC, and the resultant diffraction intensity can increase by controlling the phase. The SGC-assisted EIG controlled by two, three, and four coupling optical fields are studied respectively. Remarkably, we find that the system acquires a huge diffraction intensity when the wetting layer-quantum dot (WL-QD) field is high in the case of four coupling fields. © 2020 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

Various concentrations of CuNPs (250, 500, and 750 mg/mL) alone and combined with albendazole (ALZ, 200 mg/mL) were exposed to protoscoleces collected from the liver fertile hydatid cysts of infected sheep for 5−60 min in vitro and ex vivo. Next, the eosin exclusion test was applied to determine the viability of protoscoleces. Caspase-3 like activity of CuNPs-treated protoscoleces was then evaluated using the colorimetric protease assay Sigma Kit based on the manufacturer's instructions. Results: Scanning electron microscopy (SEM) results showed that the particle size of CuNPs was 17 and 41 nm with the maximum peak at the wavelength of 414 nm. The maximum protoscolicidal activity of CuNPs was observed at the concentration of 750 mg/mL in vitro, so that 73.3 % of protoscoleces were killed after 60 min of exposure. Meanwhile, the mortality of protoscoleces was 100 % after 10 min of exposure to 750 mg/mL of CuNPs along with ALZ (200 mg/mL). Nevertheless, the findings proved that CuNPs even in combination with ALZ required a longer time to kill protoscoleces ex vivo. After 48 h of treating protoscoleces, CuNPs in a dose-dependent manner and at doses of 250, 500, and 750 mg/mL induced the caspase enzyme activation by 20.5 %, 32.3 %, and 36.1 %, respectively. Conclusion: The findings of the present investigation showed potent protoscolicidal effects of CuNPs, especially combined with albendazole, which entirely eliminated the parasite after 10−20 min of exposure. The results also showed that although the possible protoscolicidal mechanisms of CuNPs are not clearly understood, the inducing apoptosis through caspases is one of the main protoscolicidal mechanisms of CuNPs. However, supplementary studies, especially in animal models and clinical settings, are needed to approve these results. © 2021 The Authors | Elsevier Masson s.r.l. | 7533322 | |

During the recording process, it is usually contaminated with different kinds of noise which includes power-line interference, baseline wandering and muscle contraction. In order to clean the ECG signal, several noise removal techniques have been used such as adaptive filters, empirical mode decomposition, Hilbert-Huang transform, wavelet-based algorithm, discrete wavelet transforms, modulus maxima of wavelet transform, patch based method, and many more. Unfortunately, all the presented methods cannot be used for online processing since it takes long time to clean the ECG signal. The current research presents a unique method for ECG denoising using a novel approach of adaptive filters. The suggested method was tested by using a simulated signal using MATLAB software under different scenarios. Instead of using a reference signal for ECG signal denoising, the presented model uses a unite delay and the primary ECG signal itself. Least mean square (LMS), normalized least mean square (NLMS), and Leaky LMS were used as adaptation algorithms in this paper. © 2021 Institute of Advanced Engineering and Science.

It is considered as widely health problem and is an uncontrolled disease. The aim of the study is to identify of Leishmania species that cause skin lesions among patients in Thi-Qar Province, South of Iraq, also to detect some virulence factors of L. tropica. This study includes three local locations, Al-Hussein Teaching, Suq Al-Shyokh General and Al-Shatrah General Hospitals in Province for the period from the beginning of December 2018 to the end of September 2019. The samples were collected from 80 patients suffering from cutaneous leishmaniasis, both genders, different ages, various residence places and single and multiple lesions. Nested-PCR technique was used to amplify kinetoplast minicircle fragments DNA (kDNA). Conventional-PCR was performed for determination of some virulence factors (LPG1, GP63, CPA and PPG1 genes). The electrophoresis findings of kDNA gene showed two species of the parasite found in the study area, 65 samples were positive for cutaneous leishmaniasis, L. tropica at 750bp and L. major at 560bp. Generally, L. tropica (57.5%) was the most common specie and L. major (23.75%) appeared in a low level. There are no significant differences between the infections of males and females, while there are significant differences at the comparison between age groups. All virulence genes (LPG1, GP63, CPA and PPG1) appeared in all L. tropica isolates with high percentage (100%). L. tropica is the major specie which that caused CL in Thi-Qar province, while L. major appeared in low incidence. The virulence genes, which were reviewed, are necessary and important in pathogenesis of L. tropica. © 2021 University of Baghdad. All rights reserved. | University of Baghdad | 20788665 | |

Each player chooses one of two strategies with probabilities x and 1-x, where the subjective players bias their choices of the probabilities to be w(x) and w(1-x) to reflect the probability weighting effect of PT. We find that players' behavior is affected by the total number of players and the number of each type of player (objective or subjective). We show that increasing the number of participating firms encourages the information sharing strategy and the behavior becomes similar for both types of players. Subjective players' are affected more by increasing the number of participating firms (the number of players). As a result, subjective players are more likely to cooperate by sharing information and paying the costs of this sharing than objective players. We derive the conditions to achieve a locally asymptotically stable Nash equilibrium (NE) and the necessary conditions to achieve an evolutionary stable strategy (ESS). © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

When trying to access a resource from outside one's domain, various issues are arising which prevent cooperating among those domains without endangering the security of the protected resources. The main challenge is how to efficiently handle the rights of users throughout the period of interoperation between various domains. In this paper, we propose a semantic-based multi-domain authorization approach that protects the resources on the multiple domains and, at the same time, provides a steady, flexible and secure authorized access to the protected resources. Two algorithms are described, one for single-domain authorization and the other is for multi-domain authorization. Our approach is based on dynamically merging access control policy rules for various domains in one large ontology, then extracting the access decision. We develop a proof-of-concept implementation and give the complexity analysis for our approach. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

There are many applications of image inpainting include the restoration of damaged images, paintings, and movies, to the removal of selected objects, such as text, lines, subtitles, publicity, and stamps. The main objective of inpainting is to reconstruct the missing region in such a way that the observer does not come to know that the image has been manipulated. Inpainting methods can be categorized into global and local methods, the global methods are applied to reconstruct the damaged areas in the image based on the information in the data of images that have the same content. While the local methods are used to reconstruct the missing regions based on the information in the rest parts of the image. There are several local methods proposed for image inpainting such as PDE-based inpainting (PDE-BI), exemplar-based inpainting (EBI), hybrid, and texture synthesis methods. In this paper, a review of different PDE and variational methods used for image inpainting is provided. Different PDE-BI methods like 2nd-and high-order of variational and PDE methods are discussed with its pros and cons. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

Measurements of nitrate and nitrite concentrations generated after every 15 minutes were performed by the Multi-Direct-Photometer. The absorption and maximum wavelength were measured by UV and visible detecting the oxide formed during the time limit set for the water solution sample to be drawn from all types of soil studied. The results showed that nitrite and nitrite concentrations correspond to the absorption at all times, and the soil that absorbs nitrogen oxides the most is Silt. Therefore, various types of measurements and the proportions of the elements and compounds present in the soil before and after irradiation were studied. Emphasis was placed on the study of PH and EC electrical conductivity, where it was concluded that the values of electrical conduction increase as the concentration of nitrates and nitrites increases. As for PH values, it was found that silt, before irradiation are base-medial, and because of their influence on the acidic mean, which is the highest absorption ratio, after irradiation they were converted to a neutral medium or near acid, Loam soil get the opposite from a type of acid, and because they are affected by the post-irradiation to the base metal. © 2021 Iranian Society of Ichthyology. | Iranian Society of Ichthyology | 23830964 | |

A dominating set D of G is said a pitchfork dominating set (pds) if every v in it dominates at most k and at least j vertices out of D, for any non-negative integers j and k. The pitchfork domination number (pdn) of G, denoted by γpf(G) is the order of a minimum pds in G. In this paper, the inverse pitchfork domination is introduced, the definition is used for j= 1 and k= 2. Several bounds are determined that are associated with size, order, maximum degree and minimum degree of a graph. Also, this type of domination on some known graphs is calculated, like: path, cycle, complete, complete bipartite and wheel graph. The essential conditions for any graph having an inverse pitchfork domination are discussed. © 2021, The Indian National Science Academy. | Indian National Science Academy | 195588 | |

Compounds (polyester / walnut shells) were prepared, and for different weight concentrations of walnut shells (WS) additive, the proportions ranged between (0%-25%). The used cavity is rectangular in shape with a theoretically resonance frequency of around (9.9978 GHz) and exiting the dominant mode (TE101). The study shows the highest values of each dielectric constant with a weight concentration (25%) of the walnut shells, and the loss tangent without any material change to the sample. These compounds have been found to be useful in applications of electromagnetic materials such as microwave engineering and protection from biological influences when exposed to the field of microwaves, which is why it is very important to test their dielectric properties. © 2021, Anka Publishers.

The electrical sub-model is built based on fitting a surface to the current-voltage curves collected under wide range temperatures and irradiances. For this purpose, the current-voltage characteristic curves are reproduced using two different methods. The thermal sub-model considers all the effective heat transfer mechanisms to estimate the photovoltaic module junction temperature. The Newton-Raphson iterative method is used as a solving algorithm to calculate the photovoltaic junction temperature. The collected results prove the applicability of the model under a wide range of environmental conditions. © 2020 The Author(s) | Akademiai Kiado ZRt. | 17881994 | |

Microstructural characterization was conducted by means of scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS) facility, X-ray diffraction (XRD), and electron backscatter diffraction (EBSD). The mechanical property was examined using hardness test. The results revealed that cubic primary Mg2Si crystals shaped by {100} facets with an average particle size of 35 μm were successfully fabricated through the addition of 0.2 wt. % Ba element to Al-Mg-Si melts. For the first time, it is revealed that the Al4Ba compound can act as the nuclei for the primary Mg2Si during solidification, which leads to the refining of the primary Mg2Si particle size extensively. Furthermore, the formation of Al2Si2Ba and AlSiBa intermetallic compounds (IMCs) are liable for the Mg2Si particle refinement; hence, the hardness of the alloy increased from 60.21 to 67.83 Hv. Besides, thermal analysis showed that the nucleation temperatures of the primary Mg2Si phase increased with the addition of Ba. Ba additions perform a substantial role in determining the shapes of primary Mg2Si crystals, which can be altered from coarse dendritic structure (0 wt. %) to crystals with a combination of eight {111} and four {100} facets (0.08 wt. %), then to truncated cube (0.1 wt. %), and finally to a cube fully bounded by {100} facets (0.2 wt. %) with increasing Ba concentrations. This study revealed that the growth process of the cubic primary Mg2Si is due to the absorption and poisoning effect of Ba atoms, which leads to the fading of the growth rates of {100} faces of primary Mg2Si and as a result the {100} faces are exposed. Furthermore, in the modified alloy, the skeleton-type growth process of the cubic primary Mg2Si was found, in which growth steps with some hillocks were detected. © 2021 The Author(s). | Elsevier Editora Ltda | 22387854 | |

It is a rich and inexpensive source of phytonutrients, so is in demand for fibre-rich food products but creates quality issues when incorporated into bread. The purpose of this study was to characterize the physicochemical properties and phytochemical composition of different size durum bran fractions and show how they impact bread quality. Durum wheat (Triticum durum Desf.) was milled to create a coarse bran fraction (CB), which was further ground into a finer fraction (FB) which was sieved using four screens with apertures 425, 315, 250, 180, and <180 µm to create a particle size range of 1497 to 115 µm. All fractions contained phytosterol with highest in the 180 and FB, while total phenolic acids and antioxidant capacity was highest in CB and 425. Use of the fractions in a leavened common wheat (T. aestivum L.) bread formula at 10% incorporation negatively impacted bread loaf volume, colour, and texture compared to standard loaves, with CB having the least impact. Results suggest that to combine the highest phytochemical content with minimal impact on bread quality, bran particle size should be considered, with CB being the best choice. © 2021 by the authors.

Here, we aimed to review the preclinical studies (in vitro and in vivo) on the anti-leishmanial activity of chitosan and chitosan-based particles against Leishmania spp. Methods: This study was conducted based on the 06-PRISMA guidelines and registered in the CAMARADES-NC3Rs Preclini-cal Systematic Review and Meta-Analysis Facility (SyRF) database. Various English databases such as PubMed, Google Scholar, Web of Science, EBSCO, ScienceDirect, and Scopus were used to find the publications related to the anti-leishmanial effects of chitosan and its derivatives and other pharmaceutical formulations, without a date limitation, to find all the published articles. The keywords included “chitosan”, “chitosan nanoparticles”, “anti-leishmanial”, “Leishmania”, “leishmaniasis”, “cutaneous leishmaniasis”, “visceral leishmaniasis”, “in vitro”, and “in vivo”. The language for data collection were limited to English. Results: Of 2669 papers, 25 papers, including 7 in vitro (28.0%), 7 in vivo (28.0%), and 11 in vitro/in vivo (44.0%) studies conducted up to 2020 met the inclusion criteria for discussion in this systematic review. The most common species of Leishmania used in these studies were L. major (12, 48.0%), L. donovani (7, 28.0%), and L. amazonensis (4, 16.80%). In vivo, the most used animals were BALB/c mice (11, 61.1%) followed by hamsters (6, 33.3%) and Wistar rats (1, 5.5%), respectively. In vitro, the most used Leishmania form was amastigote (8, 44.4%), followed by promastigote (4, 22.2%), and both forms promastigote/amastigote (6, 33.3%). Conclusion: According to the literature, different types of drugs based on chitosan and their derivatives demonstrated considerable in vitro and in vivo anti-leishmanial activity against various Leishmania spp. Based on the findings of this review study, chitosan and its derivatives could be considered as an alternative and complementary source of valuable components against leishmaniasis with a high safety index.

The shaped metal deposition with cold wire feeding process is suitable as an alternative technique for traditional manufacturing methods, especially for complex and large-scale solid parts and it is especially used for structural components in aerospace and the manufacture and repair of dying/molds. In this paper, a new experimental setup was developed, which consists of a MIG welding source, an external cold wire feed unit and a 3-axis machine. The paper explains the design, implementation, and stages of control programing (CAD-CAM) of the developed system. Furthermore, the paper presents the important design steps from the design database using CAD to the final shape of the part to be configured. The proposed system is capable of producing parts of different shapes in sizes of more than 450 mm directly from the computer-aided design. Several components are fabricated with SS309L components to achieve the capability of the advanced proposed system. The results showed that the integrated system and the program are feasible and flexible and hence can be used to manufacture variously shaped parts. © 2021, King Fahd University of Petroleum & Minerals. | Springer Science and Business Media Deutschland GmbH | 2193567X | |

The optical gain, spontaneous emission rate, and lineshape function are calculated using non-Markovian relaxation compared with Markovian one. Gain is then connected with the rate equations model to obtain a dB gain, output power, and shot noise in these SOAs. GaN peaked at 351 nm which is preferred in optical coherence tomography applications. InN is peaked at 1028 nm which can be used in gas detection and environmental pollution monitoring. Both structures studied have high gain and low noise and nearly equivalent TE and TM gain which makes them adequate for the use in both these two modes. These calculations show the importance of InN and GaN QD nanostructure in the applications. © 2020 Wiley Periodicals LLC | John Wiley and Sons Inc | 8952477 | |

The aim of the present study was to test the ability of some Romanian peach cultivars (Prunus persica (L.) Batsch) to be propagated in vitro and then to be cultivated on their own roots. Ten peach cultivars were included in the experiment: Three dwarf cultivars ('Valerica', 'Cecilia', 'Dan') a standard control - 'Redhaven' and six commercial cultivars ('Raluca', 'Monica', 'Florin', 'Filip', 'Mimi' and 'Catherine sel. 1'). Two explants: Shoot-tips and nodes were taken at 0.5-1 cm length, sterilized with sodium hypochlorite (10%) for 15-20 min and then cultivated on Murashige & Skoog media with different growth hormones balance. The growth chamber parameters were maintained at 22°C, 2000-2500 lx and 80-85% relative humidity. The number of shoots formed, shoots length, number of leaves/shoots were analyzed. The results showed that the data were influenced by the cultivars in response to tissue culture technique with differences between the dwarf cultivars and the standard ones. Explant type also influenced the peach in vitro culture performance. © 2021 International Society for Horticultural Science.

Batsch) is one of the most popular stone fruits and includes several cultivars producing edible drupes with economic importance. Commercially largely produced in Mediterranean and, to a lesser extent, in continental climatic conditions, peach has received extensive attention in the last 30 years, a fact that has led to the expansion of cultivated areas and the diversification of available cultivars. Research carried out in USA, Canada, France, Italy, Spain and Romania has led to a large number of cultivars with remarkable agro-productive characteristics. Several breeding programs with different aims annually release large numbers of new cultivars. The aim of this study was to present the most important studies on in vitro micro-propagation of peach around the world, as well as to identify the most important achievements and prospects in the development of peach tissue culture in Romania. © 2021 International Society for Horticultural Science.

Four types of coolants have been used in this study starting with air as a baseline to compare its thermal performance with pure phase change material (PCM) which was paraffin wax and nanoparticles-enhanced phase change material (NEPCM) which were (Silicon carbide (Sic)-PCM and Diamond-PCM) with volume fraction values of (1, 3, and 5%). On the heat sink base, a constant and uniform heat flux of (8000, 10000, 12000, and 14000W.m-2) is applied. Numerical simulations have been performed to investigate the effect of nanoparticle material and concentrations of nanoparticles on cooling performance of heat sink. The findings elucidated the cooling performance of MHS is enhanced with PCM compared with air and suspension nanoparticles lead to improve the thermal conductivity of (NEPCM) comparing with pure PCM, that causing expedite the melting process and enhancement of cooling performance. Also, as the concentration of nanoparticles increased, the heat transfer rate for (NEPCM) enhanced and decreasing the time of the melting process. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17426588 | |

Virtual network has been looked as a helping future network technology, during multiple diversified virtual networks that can work on a participated infrastructure. So, to study and exam the management mechanism of future network, we try to improve and accomplish a model of networking operation for system virtual network. The model basically simulates a network multi-layer topology that integrates a virtual network into a virtual network system (VNS). Moreover, it also possible to simulate the operating status and network error. The validation results of model show three advantages that can effectively simulate the virtual network (VS) (a) Simulate the errors of both virtual networks and the primary network (PN), and the selection results depend on the simulated (b) simulate and test multilayer network topology model (c) working virtual network establish tests graphically and providing comparison through embedding various algorithms. finally, in order to make it easier to assess network systems beyond current simulators' competence field, a new virtual network simulation model is designed and performed. © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

High-energy short-wavelength ultraviolet B (UVB) is biologically effective, influencing a range of dermal processes, including the potentially beneficial production of vitamin D. In addition to the damaging effects of UVB, the longer wavelength and more abundant ultraviolet A (UVA) has been shown to be linked to an increased risk of skin cancer. To evaluate this risk requires the monitoring of the solar UVA globally on a time repetitive basis in order to provide an understanding of the environmental solar UVA irradiance and resulting exposures that humans may receive during their normal daily activities. Satellite-based platforms, with the appropriate validation against ground-based instrumentation, can provide global monitoring of the solar UVA environment. Two satellite platforms that currently provide data on the terrestrial UVA environment are the ozone monitoring instrument (OMI) and the global ozone monitoring experiment (GOME-2). The objectives of this review are to provide a summary of the OMI and GOME-2 satellite-based platforms for monitoring the terrestrial UVA environment and to compare the remotely sensed UVA data from these platforms to that from ground-based instrumentation. © 2021 by the authors.

The metapneumovirus (hMPV) is associated with both upper and lower respiratory tract infections among infants and children. Throat swabs from 250 hospitalized children with fever and respiratory distress were evaluated for hMPV and RSV. RNA extract for diagnosis of viruses by was conducted. Among 250 children evaluated in this study, 60 cases had RSV (38 RSV-A + 19 RSV-B + 3 mix infections of RSV-A and RSVB), while 25 cases had hMPV. Thirty two of the RSV-infected patients were males and 28 were females, while 13 of the hMPV-infected children were males and 12 were females .The RSV infections were detected in mainly less than one year old children and hMPV infections had mainly in more than one year old children. Both RSV and hMPV infections had occurred mainly during winter and spring seasons. It can be concluding that the respiratory syncytial virus was the major cause of acute respiratory infection in children under one-year of age while human metapneumovirus had a low prevalence in this group. © 2021 Ecological Society of India.

Correspondingly, the term ‘security’ shows unsolvable debates over its areas of application and anticipated meanings in as much as ideological elements are concerned in socio-political works. The current study provides a more textual analysis of resolutions on security as an issue requiring emergency politics. The aim is to find out discursive evidence of whether, or not, the Security Council has securitized threats and suggested extraordinary measures to ensure human rights. The study, also, provides critique of the interconnectedness between discursive, social and political engagement in the discussion of international security threats/measures. For this aim, I have adopted a multidisciplinary approach falling within the mantle of critical discourse analysis for the analysis of the Security Council Resolutions (2001-2019). The results revealed that there was limited discursive means available in the resolutions that ensured the protection of human rights norms, which, on the contrary, put people’s lives at risk. © 2021 Asian E F L Journal Press.

The study examines the interface between knowledge, meaning and social practices in terms of text and context when speakers cognitively reconceptualize terrorism discourse as a professional practice and maintain their stance over social issues. Drawing on a multidisciplinary approach of discourse analysis and corpus linguistics, the study sets out to analyse the discursive representation of terrorism in TED talks delivered between 2002 and 2019, focusing on explanation strategies of definition, description, denomination and metaphor. The results revealed that TED talks’ discourse was a less popularised genre regarding terrorism, marked by specialised terms of traditional right discourse of military actions, and impersonal reference for private intentions of building up expert identity. © 2021TED Talks, Terrorism, Popularization discourse, Discourse analysis, Corpus linguistics © 2021 | Elsevier Ltd | 24058440 | |

It has been found that the properties of the random laser are affected by these three parameters significantly, as it was observed that the emission spectrum reached its best value when adding the of polyvinylpyrrolidone polymer. As for the FWHM and the laser threshold, their value decreased from 38 to 35 nm and from 0.71 to 0.68 A respectively after adding the polymeric material. These results were achieved at concentration of 5×10–4 M and cell thickness 0.1 cm. Improving the properties of random lasers is considered a significant step in creating optical devices useful in medical applications and biosensors. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature. | Springer | 3068919 | |

Molecules are attractive candidates for thermoelectricity because they can be synthesised with the atomic precision, and intriguing properties due to quantum effects such as quantum interference can be induced at room temperature. Molecules are also expected to show a low thermal conductance that is needed to enhance the performance of thermoelectric materials. Recently, the technological challenge of measuring the thermal conductance of single molecules was overcome. Therefore, it is timely to develop strategies to reduce their thermal conductance for high performance thermoelectricity. In this paper and for the first time, we exploit systematically the effect of anchor groups on the phonon thermal conductance of oligo (phenylene ethynylene) (OPE3) molecules connected to gold electrodes via pyridyl, thiol, methyl sulphide and carbodithioate anchor groups. We show that thermal conductance is affected significantly by the choice of anchor group. The lowest and highest thermal conductances were obtained in the OPE3 with methyl sulphide and carbodithioate anchor groups, respectively. The thermal conductance of OPE3 with thiol anchor was higher than that with methyl sulphide but lower than the OPE3 with pyridyl anchor group. © 2021 by the authors.

In recent years, EMG signals have been used as a popular tool to generate device control commands for rehabilitation equipment, such as robotic prostheses. This intention of this study was to design an EMG signal-based expert model for hand-grasp classification that could enhance prosthetic hand movements for people with disabilities. The study, thus, aimed to introduce an innovative framework for recognising hand movements using EMG signals. The proposed framework consists of logarithmic spectrogram-based graph signal (LSGS), AdaBoost k-means (AB-k-means) and an ensemble of feature selection (FS) techniques. First, the LSGS model is applied to analyse and extract the desirable features from EMG signals. Then, to assist in selecting the most influential features, an ensemble FS is added to the design. Finally, in the classification phase, a novel classification model, named AB-k-means, is developed to classify the selected EMG features into different hand grasps. The proposed hybrid model, LSGS-based scheme is evaluated with a publicly available EMG hand movement dataset from the UCI repository. Using the same dataset, the LSGS-AB-k-means design model is also benchmarked with several classifications including the state-of-the-art algorithms. The results demonstrate that the proposed model achieves a high classification rate and demonstrates superior results compared to several previous research works. This study, therefore, establishes that the proposed model can accurately classify EMG hand grasps and can be implemented as a control unit with low cost and a high classification rate. © 2020 Elsevier B.V. | Elsevier B.V. | 9333657 | |

The synthesized catalyst samples were analyzed by different characterization techniques including powder XRD, VSM, FESEM, EDX and DRS. The Fe0@PEDOT\POTs magnetic nanocomposites have been investigated as efficient heterogeneous nanocatalysts for catalytic oxidative desulfurization (ODS) of model and real gasoil fuels. The catalytic ODS was carried out at various experimental conditions to assess the influences of individual reaction variables, such as nanocatalyst dosage, sulfur content (in model fuel), reaction time and reaction temperature. At the same experimental conditions, Keggin POTs-based catalyst (Fe0@PEDOT\PW12) exhibited higher desulfurization activities (98.6% and 93.2% for model fuel and real gasoil, respectively) than Dawson- POTs-based (Fe0@PEDOT\P2W18) catalyst (93.1% and 84% for model fuel and real gasoil, respectively). According to the results, the Fe0@PEDOT\PW12 reusable nanocatalyst can retain high desulfurization efficiency after six reaction cycles. © 2020 Elsevier Ltd. | Elsevier Ltd | 22133437 | |

Our finding demonstrated that the 5-FU has insulator behavior, but 6-MP, CP and GB have semiconductor behaviors. Results disclosed that all anticancer drugs are needed to lower energy to donating/accepting an electron to become cation/anion due to these molecules have a higher value of the negative ionization potential and electron affinity. In addition, these molecules have a higher value of the electrochemical hardness and lower value of the electronegative, which means these molecules have higher ability to electron transfer. There is a weak interaction between these drug molecules with other surrounding types or molecules due to there are higher value and lower value of the chemical potential and electrophilic, respectively. For optical properties, we found out that 5-FU and 6-MP anticancer drugs situated within the visible light region but GB and CP located within infrared region. Moreover, the λmax takes value from 314.84 nm for 5-FU (S3) to 2265.20 nm for GB (S1). Also, the electron is easily to move from HOMO to LUMO orbitals in the 5-FU molecule due to it has a higher electronic transition energy compared to other anticancer drugs. © 2020 Elsevier Ltd | Elsevier Ltd | 381098 | |

Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) are a subset of ITS widely used to solve different issues associated with transportation in cities. Road traffic congestion is still the most significant problem that causes important economic and productivity damages, as well as increasing environmental effects. This paper introduces an early traffic congestion alert system in a vehicular network, using the internet of things (IoT) and fuzzy logic, for optimizing the traffic and increasing the flow. The proposed system detects critical driving conditions, or any emergency situation blocking the road, and broadcasts remote warnings to the following vehicles. Since not all vehicles are equipped with new technologies, Liquid Crystal Display (LCD) fixed on the roads displays the alert to warn the other vehicles which have neither communication nor sensors. The system was designed with Raspberry Pi 3 Model B equipped with sensors and GPS module to emulate real-world vehicles. The results and observations collected during the experiments showed that the proposed system is able to monitor the road conditions, detect the emergency situation, and broadcast a warning message to the approaching vehicles. © 2021 University of Baghdad-College of Science.

Different PWM types have been implemented such as Sinusoidal PWM (SPWM), Space Vector (SVPWM), carrier phase shifted SPWM (CPS-SPWM) using different FPGA boards. In this paper, we designed and implemented a new circuit of a Modified Sinusoidal PWM (MSPWM) on FPGA. The circuit was described in VHDL and implemented on ZYNQ-7000 FPGA board. Before the implementation, the design was simulated using MATLAB Simulink where the MSPWM was used to control a single-phase DC to AC inverter to study the performance in terms of Total Harmonics Distortion (THD) reduction compared to SPWM. Two reference sinusoidal signals with 180-degree phase shift were generated using 8-bit accumulator and 64 values Look Up Table (LUT) based on Direct Digital Synthesizer (DDS) technique. They were compared with triangular carrier signal which has a one-third zero values at a specific interval of its period to produce four PWM signals. The resource utilization table indicates that only 9% of the LUT, 0.2% of the FF (flip flop), and 6.25% of the buffers have been used for implementing the MSPWM. © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The electronic properties of the 5-FU/pristine ZnONS and 5-FU/metal-doped ZnONS are studied by using DFT method, which implemented in the quantum espresso package. Metal impurities are utilized to recognize the suitability and optimization of the adsorption 5-FU on the ZnONS superficial. For metal-doped ZnONS and 5-FU/metal-doped ZnONS, we observed that the shape of the electronic band structure is changed. So, the electronic band gap and Fermi level are reduced and shifted up, respectively compared to the pristine ZnONS, but they still have semiconductor behaviors. Moreover, all complex structures become more stable and lower reactive due to the total energy increased. Results disclosed a weaker interaction between the pristine ZnONS and 5-FU, but there is a stronger interaction between the 5-FU and metal-doped ZnONS. We detected very exciting results. The adsorption process is depended on the type of the impurities and the distance between the 5-FU molecule and metal-doped ZnONS. So, it became stronger when we made the distance between this molecule and metal-doped ZnONS is smaller. Additionally, all structures have a lower and higher electron affinity and chemical hardness, respectively. That means these structures needed a higher energy to donating/accepting an electron to be cation/anion. Besides, there is a great interaction between the pristine ZnONS and 5-FU molecule in the present (Cu, Au, and Ag) impurities between them, but other metal impurities made a weak interaction between them. Then, we can utilize the new substrate (metal-doped ZnONS structures) as a carrier to the 5-FU drug molecule. © 2020 Elsevier B.V. | Elsevier B.V. | 2210271X | |

Thus, fibres are embedded in concrete to improve its ductility. However, pulling out steel fibres from concrete structures is one of the most encountered issues in the fiber-reinforced concrete, which hinders using their maximum capacities. Objectives: Thus, closed steel fibres (square shape) were incorporated into concrete mixes to evaluate their impacts against the pulling-out effects and assess the feasibility of applying Closed Steel Fibres (CSFs) on the fresh and hardened concrete properties. Hooked end and straight steel fibres were also investigated for comparison. Methods: The utilized steel fibres were incorporated with lengths of 20, 30, and 40 mm, and volume fractions of 0.25%, 0.50%, and 0.75%. Silica Fume (SF) was involved in the fibre-reinforced concrete mixtures at 7% of the cement weight. Results: Paper outcomes stated that the inclusion of steel fibres involved different impacts on the concrete compressive strength depending on the applied fibre geometries and content. Conclusion: CSFs exhibited better performance against the pulling-out effect from the surrounding concrete structure than those of hooked end and straight steel fibres. However, the addition of CSFs has increased the concrete permeability due to their poor space-filling capacity. © 2021 Al-Qutaifi & Bagheri. | Bentham Science Publishers | 18741495 | |

Relying on the conventional techniques to test patients such as RT -PCR has two major drawbacks; a long time to get results and a lack of test kits. Therefore, data mining with machine learning techniques has been suggested to investigate covid-19. In this work, chest x-ray image-based covid-19 detection approach is proposed. Three types of x-ray images Covid-19, Pneumonia, and Normal, are used in two frameworks: image visualization and image segmentation. First, the x-ray samples are visualized using histograms to analyze the pixel-value distributions. The visualization approach helps covid-19 specialists to discover the intensity level of infection by examining the corresponding histograms. Second, a segmentation approach is developed with a k-mean algorithm to provide extra image tuning for infected areas. Three different centroids are used to provide different tuning granularity levels. The suggested frameworks give a fast and reliable methodology to help physicians to decide whether there is a virus or not in the x-ray sample. This is done statistically by histograms and visually by monitoring the segmented infected areas. © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Alcohol septal ablation is a treatment option for severely symptomatic drug-refractory hypertrophic obstructive cardiomyopathy. This study aimed to determine the outcome of alcohol septal ablation in 20 patients from a single center in Iraq. Methods: Twenty patients with age less than 60 years had undergone alcohol septal ablation between May 2013 and February 2019 at Nasiriya Heart Centre. Patients were selected for alcohol septal ablation depending on the clinical and angiographic suitability of septal perforator branches. Clinical, electrocardiographic, and echocardiographic parameters were evaluated in the periprocedural period and during follow-up. Results: Only three patients (15 %) remained in NYHA class III after 6 months of follow-up, one of them underwent repeated alcohol septal ablation with successful improvement at 6 months follow-up, and the other two patients awaiting reevaluation at 6 months to decide for repeating ASA. Significant reduction of left ventricle outflow gradients (LVOTG) and septal thickness were observed during 6 months follow-up. Beyond 6 months, except for 3 patients, there was no further decrease in either septal thickness or LVOTG noted. The incidence of right bundle branch block (RBBB) after ASA was 45 % % and 3 patients (15 %) needed PPM implantation. There was no cardiovascular death on follow-up. Conclusion: Alcohol septal ablation is a safe and effective option for severely symptomatic patients, less than 60m years with HOCM because of its low risk and its significant clinical, echocardiographic, and hemodynamic improvement. The overall in-hospital adverse cardiovascular events were low and few patients required in-hospital permanent pacemaker implantation. © 2021 SOLEN s.r.o..

Variable factors including infectious pathogen can predispose for this exacerbation. The aim of this study is to evaluate the role of intestinal protozoa in COPD exacerbation. A total of 56 patients with COPD were included in this study. Patients were categorized into two groups based on the frequency of exacerbation during the last 6 months: those with ≤1 exacerbation (32 patients) and those with ≥2 exacerbations (24 patients). Stool specimens from each patient were collected two times (one week interval) examined for intestinal parasite. In univariate analysis, rural residence and parasitic infection were more common among patients with frequent exacerbation (45.83% and 33.33%, respectively) than patients with non-frequent exacerbation (18.75% and 9.38%, respectively) with significant differences. However, in multivariate analysis, only body mass index >25 kg/m2 (OR=4.59, 95%CI=1.18-17.86, P=0.028) and parasitic infection (OR=5.51, 95%CI=1.01-30.18, P=0.049) were independently associated with COPD exacerbation. These data indicate a significant association between frequent COPD exacerbation and infection with some intestinal protozoa. However, the cause-effect relationship is debatable. | NLM (Medline) | 22990631 | |

A total of 375 patients (211 males, 164 females) in Thi-Qar Province, southern of Iraq were examined. Twenty-four (16 males, 8 females) patients confirm to have giardiosis and 20 healthy control group were withdrawn (5) ml of venous blood to conduct immunological tests to determine the quantitative for level of IL-2, IL-4 and IL-10 in a manner (ELISA). The result showed, the overall infection rate of G. lamblia was 6.40%, according to gender, higher infection rate was recorded in males 7.58% compared to the females rate 4.87% no significant differences were observed between gender. The highest rates of giardiosis observed in age group (30-45), which reached 7.04% and there is no significant difference showed in the infection of different ages under study (P≤0.05). The results showed a significant increases in the level of interleukins and the amount of IL-2, IL- 4 and IL-10 in patients (26.90, 17.43 and 14.71), respectively, was higher than those of healthy control (13.32, 10.25 and 10.55). The conclusion of this study demonstrated that the rate of infection was higher in males than in females and the age group (30-45) have the highest infection rates. The levels of interleukins (IL-2, IL-4 and IL10) were increased in the infected patient when compared to healthy persons, from this, we can deduce that pro-inflammatory and antiinflammatory interleukins have an important role in the infection of Giardia lamblia. | NLM (Medline) | 22990631 | |

Little attention has been given to visualize and monitor changes or differences in the local generation of PtdIns (4,5) P2 and PtdIns (3,4,5) P3 in the cell membranes of MDA-MB-231 breast cancer cell lines. Methods: PLCδ1-PH-GFP and Btk-PH-GFP were used as biosensors to detected PtdIns (4,5) P2 and PtdIns(3,4,5)P3 respectively. These biosensors and antibodies were transfected, immuostained and then visualized by confocal microscopy on different cell surfaces. Results: Our results showed that PLCδ1-PH-GFP/mCherry was localized at the cell membrane, while Btk-PH-GFP/mCherry was sometimes localized at the cell membrane but there was also a large amount of fluorescence present in the cytosol and nucleus. Our results also showed that the cells that expressed low levels of Btk-PH-GFP the fluorescence was predominantly localised to the cell membrane. While the cells that expressed high levels of Btk-PH-GFP the fluorescence was localization in the cytosol and cell membrane. Our results demonstrated that both anti-PtdIns(4,5)P2 and anti-PtdIns(3,4,5)P3 antibodies were localized everywhere in cell. Conclusions: Our results suggest that PLC51-PH-GFP and Btk-PH-GFP/mCherry have more specificity, reliability, suitability and accuracy than antibodies in binding with and detecting PtdIns(4,5)P2 and PtdIns (3,4,5)P3 and in studying the molecular dynamics of phospholipids in live and fixed cells. © 2021.

Accordingly, herpes zoster or shingles mainly occurred among adults with a consider-able percentage of infection in all months of the year, higher in winter and spring than that detected in summer in temperate climates. For example, 10–20% of adults older than 50 years usually suffer from at least one case of zoster attack during their lifetime. Moreover, about 30% of the population are at risk of undergoing and developing shingles during their life at some points. It is estimated that 1 million adults in the United States of America (USA) are affected with shingles annually. According to previously reported data and as a result of the small number of researches related to following up the rate of infection with herpes zoster among the population of Iraq in general and Thiqar Governorate, this study aimed to deter-mine the actual percentage of this disease, as well as to study the direct impact of risk factors for people in general and patients with viral skin diseases, in particular, and the extent of interdependence between these factors and the rate of herpes zoster infection. Therefore, this study pursued to identify the incidence of herpes zoster among patients with other skin infections. Also, to establish possible correlations between the incidence of herpes zoster infection and different factors detected, such as family history, number of family members living as a closed family, and other risk factors among male and female HZ patients compared to the control group. There were 100 people, 50 patients, and 50 control, males and females with an age range between 10 to 80 years. All data such as age, gender, lesion site, residency, occupation, previous history of coronavirus disease (COVID-19), Blood groups were collected applying a questioner. Results of the number of cases infected with herpes zoster showed an increase in the level of infection among males compared to females. In addition, the incidence was 30 males (60%) over 20 females (40%). Furthermore, there was a high increase (16-22%) in the incidence of infection in the age groups from 50-70 years, whether in females or males, the age groups most vulnerable to infection. The presence of skin lesions is represented by vesicles in different areas of the body. The highest incidence among patients with shingles was in the sacral region (32%), followed by the lumbar region (26%), then the cervical region (22%), and the thoracic region (16%). © 2021, Venezuelan Society of Pharmacology and Clinical and Therapeutic Pharmacology.

Nine samples collected from the market (5 samples onion and 4 sample Garlic), which classified according to their origin. Using 3''x3'' NaI (Tl) gamma ray spectroscopy system, the radioactivity concentrations of the natural radionuclides radium-226, thorium-232 and potassium-40 were determined. The results obtained showed that the average concentration of radioactivity of radium-226, thorium-232 and potassium-40 is 3.398 Bqkg-1, 4.667 Bqkg-1 and 216.738 Bqkg-1, respectively, for onion and 2.808 Bqkg-1, 3.524 Bqkg-1, and 172.064 Bqkg-1 for garlic. The results also showed that the average annual total effective dose of the three nuclides is 122.955 lSv:y-1 for onion and 97.231 lSv:y-1for garlic. Other relevant risk parameters were also calculated, such as equivalent activity concentrations, absorbed dose, excess lifetime cancer risks, and other health risk parameters. One of the most important conclusions reached by this study is that the natural radioactive elements in onions and garlic do not pose a great danger to their consumers, especially those infected with the COVID-19. Because the concentrations of these radioactive elements do not exceed the permissible limits recommended by recognized scientific organizations and agencies such as International Commission on Radiological Protection (ICRP), United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and World Health Organization (WHO). © 2021 Elsevier Ltd.

College, University of Thi-Qar, Iraq; Al-Asadi, A.K., Civil Eng., Eng. College, University of Thi-Qar, Iraq | This research investigated the performance of lightweight concrete infilled inside steel tubular truss girders. Six specimens of lightweight concrete infilled steel tubular (LWCFST) truss girders were tested. The main variables were the effect of the existence of concrete within the chords and the reinforcing steel bars added into the bottom chord. The lightweight concrete in the bottom chord was reinforced with one or two bars with a nominal diameter of 10 mm, whereas the concrete in the top chord was remained unreinforced. This study demonstration the ultimate loads, flexural strength, load–displacement curves at the mid-span, longitudinal strain curves for chords at mid-span, deflections along the span, and the modes of failure of the tested specimens. The results showed that the existence of the lightweight concrete into the chords increases the strength of the LWCFST truss girder by about 41.2%, also gives them better ductility as compared to the hollow truss girder, and was increased by about 7.6 % to 24.8 % when added reinforcing to concrete in the bottom chord. The adding of reinforcement to the lower of the bottom chord gives the best increase in the ultimate load. © 2021 Elsevier Ltd. All rights reserved. | Elsevier Ltd | 22147853 | |

The beams subjected to preload were repaired with two different techniques using CFRP sheet (U-warp and W-warp) and then tested to fail under a four-point loading system. The results showed that pre-loading at high levels had a detrimental effect on the shear-deficient concrete beams, on the other hand, CFRP sheets helped to restore as well as increase the ultimate load-carrying capacity of most of the beams. Experimental results prove that Repairing previously damaged beams not only helps them to recover but also greatly increases their ability to resist premature shear failure. © 2021 Elsevier Ltd.

Due to the importance of this sector economically and in terms of energy supply, one of the most important applications of nanomaterials is their large scale use to remove or minimize the hurdles that the oil and gas industry faces. The hydrothermal method was used to prepare novel Rhodium borate nanoparticles, which were made by first obtaining Rhodium oxide from Rhodium acetate, then reacting with boric acid and other cofactors. The efficiency of the process for generating Rhodium borate nanoparticles was extremely high. The efficiency of the process for generating Rhodium borate nanoparticles was extremely high. The validity of the obtained results was confirmed by the diagnostic and estimation procedures utilized in this work (XRD, FT-IR, SEM, and TEM). One of the most critical processes in petroleum processing is demulsification. To avoid issues during oil transportation and handling, oil emulsions must be broken down. Because of the water content and dissolved salts in the aqueous phase of the emulsion, the presence of water in the crude oil is undesirable and can lead to pipeline corrosion and increased transportation costs. The physical and chemical features of crude oil from the Halfaya oil field in southern Iraq, which is known to contain a certain percentage of water, have been investigated. Rhodium borate (Rh2O3. B2O3·H2O) (DF1) nanoparticles were utilized in this work to separate water from crude oil emulsions. Effective aggregates exist in the synthesized Rhodium borate nanoparticles, allowing them to operate as demulsifying agents. The separation of water from the emulsion by the produced rhodium borate (DF1) and the standard demulsifier (RP96BQ) used in the same oil field at constant temperature (60 °C) and with varying concentrations was compared in this study using crude oil samples. A high separation efficiency was obtained for the prepared nano demulsifier with a percentage of up to (84.2%) compared with the standard demulsifier (RP96BQ). © 2021 Elsevier Ltd.

The algorithm used is a dynamic-static topology of particle swarm optimization (DS-PSO) algorithm. The subject of non-linear mean square error (SE) optimization between the original and required filter responses in the passband, stopband, and transition band while tolerating permitted ripples in those bands was studied. Experimental results indicate a significant decrease in SE rates of passband and stopband with used technique, where SE values of digital IIR filter with DS-PSO were better than they were with evolutionary algorithms like DI-PSO (dynamic inertia PSO) and MDI-PSO (modified dynamic inertia PSO), at rates from about 50%-90% and 10%-90%, respectively, depending on filter's order. As a result, as compared to evolutionary algorithms, the suggested method creates greater fidelity coefficients and stable digital filters. © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Our findings show that dopamine has a dielectric behavior, whereas quinone and L-DOPA have semiconductor behaviors in the ground and excited states. By computing the optical properties, we disclose that the electronic transition spectrum of dopamine, quinone and L-DOPA are observed in the ultra-violet region, visible spectrum, and (ultraviolet and visible regions), respectively. Other properties, such as ionization potential, electronic affinity, hardness and softness are also calculated due to their importance in sensor applications and sensing. © 2021 Mohammed L.

IoT-enabled cameras significantly help in collecting flowers images in real-time on the farm. To Classify a large dataset of flowers images with multi-species, we need a dedicated and sufficient AI model. The purpose of those captured images is to transfer their features into numerical values like the common IRIS dataset. This research investigates a perfect solution to extract the most relative features from the collected images so that engineers can have IRIS attributes from their original images. Those features represent the IRIS flowers; Sepal width and height, and Petal width and height. The applied methodology is a Conventional Neural Network model with four different architectures; GoogLeNet, VGG-16, AlexNet, and ResNet-50. These models would extract features of the image and then select the most efficient ones. Experiments have proved that SVM has accuracy with 98.89% of classifying the selected features. In the last step, using the comparative technique, nine algorithms were used to classify the IRIS species, which reached 97% of the accuracy. © 2021 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

According to the (IAE), around 80% of global energy demand has been met by fossil fuels in recent years, resulting in an increase in CO2 emissions as the primary greenhouse gas. Switching to renewable energy sources and using more energy-efficient energy systems are vital for mitigating environmental challenges and reducing our reliance on fossil fuels, among other things. Hydrogen fuels are primary renewable resources because of their reduced cost and ability to produce net-zero CO2 emissions. In the present study, a system is designed to generate power and liquid hydrogen from geothermal sources. The generated power by employing either the organic Rankin cycle (ORC) or absorption power cycle (APC) is compared to seek the best cycle performance from power generation standpoint. A comprehensive thermodynamic and economic modeling is carried out for the proposed system. In addition, a parametric study is applied to see which parameters affect the performance of the system. Multi-objective optimization is carried out to find the best operating point of the hydrogen liquefaction energy system. The system demonstrates better performance when APC is applied for power generation. The cost of generated liquid hydrogen by ORC and APC is 3.8 $/kg.LH2 and 3.6 $/kg.LH2, respectively. Furthermore, 0.014 $/kWh of electricity cost is reached by ORC compared to 0.012 $/kWh of APC. Parametric analysis shows that the higher the temperature and flow rate of the brine of geothermal fluid, the higher the efficiency and the lower cost. Finally, the multi-objective optimization pinpoints that the system's efficiency and unit product cost at the optimal ORC-based design is 33.85% and 0.0121 $/kWh. In comparison, the APC demonstrates better performance by 34.5% and 0.011 $/kWh. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

Clinical studies are assessing the optimal duration with the most favourable risk to benefit ratio. The efficacy of P2Y12 receptor inhibitors comparable to aspirin in preventing recurrent ischaemic events in patients with coronary artery diseases. Objectives: To investigate the outcomes of short-duration dual antiplatelet therapy after PCI with early discontinuation of aspirin while maintaining patients on P2Y12 inhibitor through systematic review and meta-analysis of available literature. Methods: We systematically searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov. We included randomized controlled studies that measured clinical outcomes of efficacy (mortality and ischaemic events) and safety (bleeding) of short and standard-duration dual antiplatelet therapy. The protocol of this study was registered in the interna-tional prospective register of systematic reviews PROSPERO registry (CRD42020171468). Results: Four randomized controlled trials were included; GLOBAL LEADERS, SMART-CHOICE, STOPDAPT-2, and TWILIGHT. The total number of patients was 29,089. The safety outcomes showed a significant reduction in major bleeding events with short-duration dual anti-platelet therapy; the risk ratio was 0.61 (95% CI 0.38-0.99; z=2,00, p=0.05). There was no differ-ence between short and standard-duration dual antiplatelet therapy regarding efficacy outcomes (al-l-cause death, major adverse cardiovascular events, myocardial infarction, stroke, and stent throm-bosis). Conclusion: Short-duration dual antiplatelet therapy followed by P2Y12 inhibitor monotherapy after PCI is a feasible option and can be adopted, especially in patients with a high risk of bleeding. © 2021 Bentham Science Publishers. | Bentham Science Publishers | 1573403X | |

We consider the process of Arabization/domestication of Shakespeare's plays since Najib al-Haddad's adaptation of Romeo and Juliet and Tanyus' Abdu's adaptation of Hamlet, to the achievements of Khalīl Mutran and Muhammad Hamdi. We underline, as particular examples of Shakespeare's appropriation, the literary response of Ali Ahmed Bakathir, Muhammad al-Maghut and Mamduh Udwan, with a particular stress on Khazal al-Majidi and his adaptations of Shakespeare's plays. All these writers reposition Shakespeare's plays in an entirely different cultural space. © by the author, licensee Łódź University - Łódź University Press, Łódź, Poland.

If the concept of foreignization leads the reader to the source text through a foreign cultural contribution to the target culture, domestication brings the source text closer to the reader’s culture. We apply Venuti’s theory to literary translation from English into Arabic to demonstrate the translator’s involvement in this form of cultural transfer by providing relevant examples: Hemingway’s The Old Man and the Sea, and Alan Lightman’s Einstein’s Dreams (from English into Arabic), and Mark Twain’s The Adventures of Huckleberry Finn (from English into Arabic, Romanian, and Polish). © 2021, Editura Universitaria Craiova.

Encryption is known to be a very critical step in the security of multimedia applications. This paper proposes the Playfair, and OTP based image encryption-compression method using integer Haar transform. Initially, the proposed method encrypts the image using integer Haar transform with the One Time Pad (OTP) algorithm and the Playfair encoding. Finally, Inverse Discrete Wavelet Transform (IDWT) is applied to get the ciphered encoded image. The decoding part is driven automatically by inverting the operations of the encoding part. The quality of encrypted-decrypted images is assessed using Histogram Analysis, NPCR, UACI, PSNR, SSIM, GLCM correlation coefficient and Entropy. It is evident from visual inspection of the images and quality assessment parameters that the proposed method works effectively. © 2021, Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 18650929 | |

This paper demonstrates the feasibility of employing the neural network in the solder joint useful lifetime estimation. A dataset is prepared for training a deep neural network under different conditions using finite element simulations. The contributory parameters including thermal specifications, solder joint geometry and solder joint type are considered in 420 finite element simulations. While the proposed approach has a remarkably quick reliability assessment, the predicted results showed a maximum root mean square error of 3.2%. The results reveal that there exists an optimum solder joint volume in which the maximum useful lifetime under the certain thermal loading. Also, it is found that the hourglass type solder interconnection has better performance in comparison with barrel type solder interconnection as the reliability perspective owing to the more gentle triaxiality factor. Ability of rapid reliability analysis and effects consideration of key parameters on the solder joint reliability make this proposed method attractive in the design stage of electronic devices. © 2021 Taylor & Francis Group, LLC. | Taylor and Francis Ltd. | 15376494 | |

Many studies have shown that heavy metal exposure and trace element levels in the body are the most critical etiologies for cancer development. As a result, the goal of our research was to assess the imbalances in the serum concentrations of selected elements (Cu, Co, Se, Ni, Cd, and Pb) in post-operative GC patients against healthy participants/ controls. Methods: The metal levels were determined using a nitric acid/perchloric acid-based wet digestion technique and flame atomic absorption spectrometry, Serum levels of CEA were measured using a two-site immunoenzymometric assay, which is performed entirely in the AIA-PACK SLa test cups. Results: Pb, Cd, and Ni concentrations were found to be significantly higher in the blood of GC patients than in the blood of controls, but Cu and Co levels were significantly lower in the blood of GC patients than in the blood of controls. In the blood of post-operative GC patients, correlation analysis revealed a positive association between CEA-Cd, CEA-Pb, and CEA-Ni, while the correlation was negative for CEA-Cu. These findings were statistically significant (p < 0.05). Conclusion: According to our findings, low Co and Se levels, as well as high Pb and Cd levels, may have a role in the development of stomach cancer.

Most patients are infants and young children with a history of burns caused by liquids. Objective: The present study aims to present all patients with burn hemangiomas treated at our institutions with a full clinical and histopathological assessment. Patients and Methods: This case series includes 34 cases that were treated during the period from 2016 to 2021. Results: A total of 34 patients (16 female/18 male, mean age of 17.6 years) were included. Two age groups presented: infants and children (n = 22, age range 0.5-8 years, 10 female/12 male), and adults (n = 11, age range 25-44 years, 6 female/6 male). Lesions appeared 1-2 weeks following predominantly second-degree burns, and multiple lesions predominated in infants and children. The lesions evolved to large lesions within weeks, and these appeared to be either static or involute. The histopathology was compatible with hemangioma, rather than pyogenic granuloma. Conclusion: Burn hemangioma should be considered a new variant of hemangioma rather than a type of pyogenic granuloma that follows second-degree burns. They have many similarities with infantile hemangioma, both clinically and histopathologically. © 2021 S. Karger AG, Basel. Copyright: All rights reserved. | S. Karger AG | 10188665 | |

Alcohol consumption, particularly heavier drinking is identified as an essential factor to develop health issues, such as high blood pressure, immune disorders, and heart diseases. To support health professionals in diagnosis disorders related with alcoholism with a high rate of accuracy, there is an urgent demand to develop an automated expert systems for identification of alcoholism. In this study, an expert system is proposed to identify alcoholism from multi-channel EEG signals. EEG signals are partitioned into small epochs, with each epoch is further divided into sub-segments. A covariance matrix method with its eigenvalues is utilised to extract representative features from each sub-segment. To select most relevant features, a statistic approach named Kolmogorov–Smirnov test is adopted to select the final features set. Finally, in the classification part, a robust algorithm called AdaBoost k-means (AB-k-means) is designed to classify EEG features into two categories alcoholic and non-alcoholic EEG segments. The results in this study show that the proposed model is more efficient than the previous models, and it yielded a high classification rate of 99%. In comparison with well-known classification algorithms such as K-nearest k-means and SVM on the same databases, our proposed model showed a promising result compared with the others. Our findings showed that the proposed model has a potential to implement in automated alcoholism detection systems to be used by experts to provide an accurate and reliable decisions related to alcoholism. © 2021, Springer Nature Switzerland AG. | Springer Science and Business Media Deutschland GmbH | 3029743 | |

Cytokines play critical roles in cellular response to viral infection. It has also been reported that’s susceptibility of the ABO blood type people to several viral infection. In this study, we evaluated interleukin 6 (IL-6), interleukin 8(IL-8), and interferon gamma (IFN-γ) levels in aborted women infected with parvovirus B19 (B19+/Abr+) and uninfected with B19(B19-/Abr+) in comparison with healthy women (B12-/Abr-) and susceptibility of their RhD blood type to contract B19. Methods: B19+/Abr+ were diagnosed using IgM and IgG antibodies against B19, and the concentrations of IL-6, IL-8, and IFN-γ were determined using enzyme-linked immunosorbent assay (ELISA) test in both B19+/Abr+, B19-/Abr+, and B19-/Abr-. Here, we also collected blood groups, number of abortion, and gestational ages from 200 B19+/Abr+ along with the same number ofB19-/Abr+ and B19-/Abr-. Results: The levels of IFN-γ were higher in serum of B19-/Abr+andB19+/Abr+ group in comparison to B19-/Abr-, while the serum levels of IL-6, IL-8were increased in B19+/Abr+ group in comparisontoB19-/Abr+ and B19-/Abr-. Our analyzed data also showed that aborted women with RhD+ are more susceptible to contract s B19 than people with RhD-blood type. Conclusions: B19 infection may differently modulate the amount of cytokines in the plasma of aborted women. So, it can be suggested that IL-6, IL-8, and IFN-γ potentially useful as markers for inflammation intrauterine. The susceptibility/protection of aborted women against B19 might be determined based on RhD blood type. © 2021. Reports of Biochemistry & Molecular Biology.

This research study and simulation examine the design and evaluation performance of Radio Frequency over FSO (RF-FSO) wireless communication technology. These systems are implemented through medium communication link ranges to overcome excessive sensitivity of atmosphere medium and meet the requirements of a wide variety of optical wireless applications. There are two ways to achieve the application of the design mentioned above. The first way is the application of the Three modulation schemes of technology that is Amplitude shift keying (ASK), Quadrature amplitude modulation (QAM), and Quadrature phase-shift keying (QPSK) of digital modulation. The design of these modulation schemes is realized by using optiwave software to study the transmission of RF signals over the FSO channel and compare the three modulation techniques into the RF-FSO system. RF signals with the frequency range from (20 to 60) GHz is used in RF-FSO system and many carrier optical signals where the higher RF has a wider bandwidth to carrying larger information. To increase the transmission of data rates Wavelength Division Multiplexing (WDM) technology is used. The second way is based on a mathematical model which has been proposed for this study. This mathematical model calculates optimal beacon period (BI), and optimal listen interval (LI) to preventing the overlapping of time between the signals and the decrease in the required power. Using different weather conditions samples, the simulation results revealed that the best performance of the RF-FSO system is from link range, and the receiver is more sensitive. The simulation results are as follows: Two independent channels are transmitted 20 Gbps over ranges from (263 m to 6.55 km), while four channels are transmitted 40 Gbps over ranges from (257 m to 5.95 km), and eight independent channels transmit 80 Gbps over distance from (203 m to 5.2 km). © 2021.

For this deal, three types of steel fiber (straight, hooked, and corrugated steel fiber) are used. Each type of steel fiber was added in four different volume fractions. Each steel fiber shape was added separately by proportions (0, 0.5, 1, 1.5) % of the total concrete volume. Subsequently, ten 800 × 800 mm × 100 reinforced concrete slabs (three slabs for each type of fibers, one for each proportion, and the remaining one slab was the control) were cast and subjected to flexural tests. The effect of type and amount of SSF on flexural behavior of two-way slabs were studied. That, where 0.5% of steel fibers was added, the straight fibers were acknowledged in comparison to the others whereas the improvement to the stiffness was better and the ultimate load increased by 22.58%. At 1% of steel fibers, the ultimate load increased by (35, 43, and 29) % for straight, hooked, and corrugated fibers respectively which at this addition ratio the hooked fibers were the notable contributor as opposed to other types, and this observation was apparent in improving splitting and flexure strength for hardened concrete. Adding 1.5% of steel fibers to the concrete degrade the workability severely by (83-92)% for all types of steel fibers in parallel with little improvement on slabs behavior is contrary to 1% ratio, thus, the 1% is the recommended addition. © The Author 2021.

The resolvent of the operator sequence of the weighted operator is discussed, and proof is given to indicate that this operator sequence is restricted to the space of all real valued Lebesgue measurable functions that are square integrable on real numbers. The sequence of this operator's convergence to the resolvent of the second derivative operator with the individual boundary conditions is then demonstrated. Consequently, this convergence is used to analyze the results of weighted operator model in the image processing. © 2021 Forum-Editrice Universitaria Udinese SRL.

Indeed, the effect of the number of nozzles of the swirl generator on the entropic characteristics has been evaluated. The nozzles were applied for improving the performance of FPSC. For evaluating the proposed system based on the entropy concept, the effect of injection angle and mass flow rate has been considered. The selected injection angles were 30°, 45°, 60°, and 90°. Also, the total mass flow rates entered from all of the nozzles were 0.2 kg/s, 1 kg/s, and 2 kg/s. The effect of said variables on frictional and thermal entropy generations was analyzed; then, the overall energetic-entropic performance of the system was predicted using several dimensionless parameters including NE, NS, Nu∗, and heat transfer improvement (HTI). Moreover, Witte-Shamsundar efficiency (ηW-S) was applied to pinpoint the efficiency of the system. The highest value of HTI and ηW-S was 1.7 and 0.9 that achieved by "single-nozzle; A90-D50-N12.5-M0.2"and "quad-nozzle; A30-D50-N12.5-M2,"respectively. © 2021 Yan Cao et al. | Hindawi Limited | 1110662X | |

In this paper, A novel pooling method are proposed based on discrete cosine transform, this method is utilized DCT technique to reduce spatial redundancy of image by transform the spatial domain into frequency domain, which can preserve the most significant image information from the other coefficients, which represents the other details information of the image, so discard these less important coefficients. Its effect will be slight and this can reduce the eliminated information as compared with other methods. After applying DCT, we crop the most significant coefficients to be used in the reconstructed data by applying inverse DCT. then the result is combined in different methods with Max pooling and average pooling methods, this new structure can reduce the effect of discarding most important information and reduce the drawbacks of average and Max. pooling method. The results are proved that our proposed methods are outperformed some standard methods and can be used in more application. © 2021. Periodicals of Engineering and Natural Sciences.

Thus, increased number of studies, theoretically and experimentally, have been carried out to study the possibility of adopting DNA molecules in designing nanoscale thermoelectric devices. In this work, a general expression of the electron transmission probability that describes the electron transfer through one strand DNA chain has been derived using the steady-state-formalism by assuming one strand of DNA molecules as line model. The energy-dependent transmission was studied, then energy-and temperature-dependent Seebeck coefficient, and thermoelectric characteristics of four one strand DNA sequences: (A-A)10, (C-C)10, (G-G)10 and (T-T)10 are theoretically studied. According to the obtained results, it is found that the transmission behavior (magnitude and position) is varying with the type of DNA sequence. Also, the energy dependent Seebeck coefficient (S-E) curves clearly show a nonlinear energy-dependence, while the relationship between Seebeck coefficient and temperature (S-T) is linear. Thermoelectric power factor as a function of temperature was found to be enhanced with the temperature increment for the four types of DNA nucleobases. The highest values of thermoelectric power factor belong to thymine (120Wm-1K-2) and cytosine (60 Wm-1K-2), that nominate them as outstanding candidate thermoelectric materials to be adopted in the fabrication of one strand DNA-base nanoscale thermoelectric devices. © 2021, Anka Publishers.

This paper proposes a novel model for the robust depth estimation of RGB-D images through local and nonlocal manifold regularizations. The first stage called deep depth prior manifold (DDPM), is inspired partly by the deep depth prior (DDP) model, that is a deep convolutional neural network (CNN) integrated with a local manifold regularization term. The local neighboring relationships between depth pixels and color images are employed to promote smoothing in the results. The Laplacian Eigenmap technique used for local manifold modeling produces over-smooth depth map. To improve the quality of the reconstructed image, a nonlocal manifold modeling stage was suggested, where the similarity between the depth and the corresponding color image is determined by characterizing their matching aspects. These objectives are aggregated within an optimization problem. Moreover, to extract edges better considering visual nonlocal characteristics, the structured low-rank Hankel approximation was adopted to better eliminate depth degradations, and to extract highly promoted edges and sharp points. Three types of the degradations were handling in this work, containing undersampling, ToF-like, and Kinect-like degradations. Experimental results indicate that the proposed method outperformed the state-of-the-art restoration techniques on standard benchmark images, in terms of well-known criteria like PSNR. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Rossin College of Engineering and Applied Science, Bethlehem, PA, United States | Large Eddy Simulations (LES) are carried out for a Francis turbine operating at an ultra-low load with and without injection. The flow rate of the turbine is 40% of the design value. The injection aims to improve turbine operation for the already unstable base case away from the design flow rate. Tangential water injection was introduced through the draft tube wall in the same and opposite runner rotation direction. The injection angle was varied (15, 30 , 45 and 60 ). Two water injection rates were applied at 4% and 8 % of the optimal design flowrate. While injection with the 4% rate and 30 in the opposite runner rotation direction helped reduce pressure fluctuations downstream of the injection inlets; no injection configuration could completely mitigate the power and pressure fluctuations. The injection was found to increase the amplitude of pressure fluctuations close to the injection inlets by 2 to 20 times the magnitude of fluctuations without injection. There was a slight reduction in mean power production (4-10% loss) by injection. The high amplitude fluctuations were observed in power signals with and without the injection. © 2021 American Society of Mechanical Engineers (ASME).

Rossin College of Engineering and Applied Science, Bethlehem, PA, United States | Design and optimization using computational fluid dynamics to enhance the hydro turbine's performance are becoming gradually more common because of its flexibility, minor detailed flow description, and cost-effectiveness. These features are not easily achievable in model testing. simulations conducted in OpenFOAM 7 characterize the flow structure inside an industrial-sized Kaplan turbine module operating at the peak design flowrate. The power signal, velocity, vorticity, and pressure field are presented over the blades and throughout the draft tube. Additionally, pressure fluctuations were probed along the draft tube wall. The simulation shows a tip vortex rope in the narrow gap between the blade tip and turbine casing. The strong influence of the swirl leaving the runner had a negative impact on the flow pressure fluctuation. Also, high vortical activity was presented near the draft tube wall, leading to turbine instability. It was demonstrated that the turbine generates 14.923 MW of average power. The power signal showed minor fluctuations induced by the vortical activity close to the runner region and the corresponding pressure fluctuations. The Fast Fourier Transform showed the system is dominated by low frequency, high amplitude fluctuations. © 2021 American Society of Mechanical Engineers (ASME).

The main parameters considered in the experimental work were the height (hf) of the HSFC layer and the volume fraction (Vf) of the steel fiber used to create the HSFC layer. The volume fractions (Vf) of steel fiber used ranged from 0.5% to 1.5% with a 0.5% increment. For each steel fiber fraction, the height of the HSFC layer was varied as 20, 40, 60 and 100% of the overall depth of the section. In addition to the control reinforced concrete beam (hf = 0.0h and Vf = 0.0%), twelve hybrid beams were cast and tested using a fourth-point bending mode. Three distinct loading states were considered in this study: cracking, yielding and ultimate loads. Additionally, the effect of the material’s hybridization on ductility, cracking stiffness, toughness and cracking behavior is discussed. The test results showed that partial replacement of plain concrete with HSFC of hf = 0.6h has approximately the same effect on the load-carrying capacity of the tested beams as compared to the full replacement (hf = 1.0h). In addition, the fiber content of 1.5% showed better results as compared to the lower contents of 0.5% and 1.0%.. © 2021 JUST.

The Density Functional Theory (DFT) at 6-311G (d, p) basis set is used to estimate the ability of vitamin C to inhibit the corrosion of the abovementioned parts. The experimental study was performed in a at human body media simulator (Hank’s balanced salt solution) at a temperature of 37°C. The compound was optimized for its ground state, physical properties, and corrosion parameters. Further, HOMO, LUMO, energy gap, dipole moment, and other parameters were used to predict the inhibitor’s efficiency. Gaussian 09, UCA-FUKUI, MGL tools, DSV, and LigPlus software was used. According to electron density, Electrostatic Surface (ESP), Total Electron Density (TED), FUKUI function, and dual descriptor were used to show the active sites of adsorption. Also, docking studies were applied to predict the effect of vitamin C on A. ferrooxidans bacteria, which causes eroding the implants. The Ti6Al4V alloy was tested at three concentrations of the VC inhibitor using the polarization method. A concentration of 55 mg/L is the best in terms of inhibitor efficiency (99.62%). © 2021, Russian Association of Corrosion Engineers.

Numerous kinds of brain tumors were discovered, which need accurate and early detection techniques. Currently, most diagnosis and detection methods rely on the decision of neuro-specialists and radiologists to evaluate brain images, which may be timeconsuming and cause human errors. This paper proposes a robust U-Net deep learning Convolutional Neural Network (CNN) model that can classify if the subject has a tumor or not based on Brain Magnetic resonance imaging (MRI) with acceptable accuracy for medical-grade application. The study built and trained the 3D U-Net CNN including encoding/decoding relationship architecture to perform the brain tumor segmentation because it requires fewer training images and provides more precise segmentation. The algorithm consists of three parts; the first part, the downsampling part, the bottleneck part, and the optimum part. The resultant semantic maps are inserted into the decoder fraction to obtain the full-resolution probability maps. The developed U-Net architecture has been applied on the MRI scan brain tumor segmentation dataset in MICCAI BraTS 2017. The results using Matlab-based toolbox indicate that the proposed architecture has been successfully evaluated and experienced for MRI datasets of brain tumor segmentation including 336 images as training data and 125 images for validation. This work demonstrated comparative performance and successful feasibility of implementing U-Net CNN architecture in an automated framework of brain tumor segmentations in Fluid-attenuated inversion recovery (FLAIR) MR Slices. The developed U-Net CNN model succeeded in performing the brain tumor segmentation task to classify the input brain images into a tumor or not based on the MRI dataset © 2021, Authors.

This paper numerically investigates turbulent heat transfer and Al2O3-nanofluid flow over a vertical double forward-facing step. A two dimensional with three different cases of vertical DFFS is conducted using K-ɛ model based on finite volume method for volume fraction of nanofluids varied for 1%, 2%,3% and Reynolds number changed from 10000 to 40000. With increasing Reynolds number, there is an increase in local coefficients of heat transfer, with the highest coefficient of heat transfer detected at Re=40000. For volume fractions of Al2O3= 3% and Reynolds numbers of 40000, the effects of step height on surface coefficients of heat transfer are described. In addition, the findings have discovered that as the volume fraction of Al2O3 nanofluids has increased, the coefficient of heat transfer has increased as well, with the maximum coefficient of heat transfer occurring at a volume fraction of Al2O3 nanofluids of 3%. Furthermore, the first step-case 2 local coefficient of heat transfer has been higher than the first step-cases 1 and 3. Increased Re number causes a sharp drop in local static pressure at the first and at the second steps. Due to the recirculation flow, there has been a reduction in velocity profile near the first and second steps, indicating an increase in heat transfer rate. Moreover, velocity counters are shown in order to demonstrate how Reynolds number affects the size of the recirculation zone. In addition, the turbulence kinetic energy counter has been shown in order to demonstrate how to achieve thermal efficiency in the second step in all the cases. © 2021 Praise Worthy Prize S.r.l.-All rights reserved. | Praise Worthy Prize S.r.l | 19749821 | |

The k-ɛ standard model based on finite volume method in 2-D are applied to investigate the influences of Reynolds number, step height, volume fractions hybrid Al2O3-Cu-nanofluid on thermal performance. In this paper, different step heights for three cases of vertical double forward-facing step are adopted by five different of volume fractions of hybrid (Al2O3-Cu-water) nanofluid varied for 0.1, 0.33, 0.75, 1, and 2, while the Reynolds number different between 10000 to 40000 with temperature is constant. The main findings revealed that rise in local heat transfer coefficients with raised Reynolds number and maximum heat transfer coefficient was noticed at Re = 40000. Also rises in heat transfer coefficient detected with increased volume concentrations of hybrid (Al2O3-Cu-water) nanofluid and the maximum heat transfer coefficient found at hybrid Al2O3-Cu-water nanofluid of 2% in compared with others. It is also found that rise in surface heat transfer coefficient at 1st step-Case 2 was greater than at 1st step-Case 1 and 3 while was higher at 2nd step-Case 3. Average heat transfer coefficient with Reynolds number for all cases are presented in this paper and found that the maximum average heat transfer coefficient was at Case 2 compared with Case 1 and 3. Gradually increases in skin friction coefficient remarked at 1st and 2nd steps of the channel and drop in skin friction coefficient was obtained with increased of Reynolds number. Counter of velocity was presented to show the re-circulation regions at 1st and 2nd steps as clarified the enrichment in heat transfer rate.

However, a major drawback of OFDM that is represented by its high Peak-to-Average Power Ratio (PAPR) of the transmitted signal, which leads to degrade the system's transmission accuracy. In this paper, a Compressed Sampling (CS) based approach is considered for reducing the PAPR without lowering its transmission capacity or affecting its Bit Error Rate (BER) performance. The proposed scheme adds a sampling stage after the IFFT block in the transmitter side, that is compressively represents the transmitted signal by fewer symbols that is transmitted instead of the original signal. At the receiver side, the received compressively sampled signal is then recovered before the FFT block by following the Basis Pursuit (ℓ1-norm) algorithm. The proposed scheme shows an enhanced PAPR and BER performances while preserving the rest of the system performance aspects. © 2021 University of Split.

The system's primary fuel is a geothermal two-phase flow. The system consists of a single flash steam-based power system, ORC, double effect water–lithium bromide absorption cooling system, PEM electrolyzer, and MED with six effects. The effect of numerous design parameters such as geothermal temperature and pressure on the net power of steam turbine and ORC cycle, the cooling capacity of an absorption chiller, the amount of produced hydrogen in PEM electrolyzer, the mass flow rate of distillate water from MED and the total cost rate of the system are studied. The simulation is carried out by both EES and Matlab software. The results indicate the key role of geothermal temperature and show that both total exergy efficiency and total cost rate of the system elevate with increasing geothermal temperature. Also, the impact of changing absorption chiller parameters like evaporator and absorber temperatures on the COP and GOR of the system is investigated. Since some of these parameters have various effects on cost and efficiency as objective functions, a multi-objective optimization is applied based on a Genetic algorithm for this system and a Pareto-Frontier diagram is presented. The results show that geothermal main temperature has a significant effect on both system exergy efficiency and cost of the system. An increase in this temperature from 260 C to 300 C can increase the exergy efficiency of the system for an average of 12% at various working pressure and also increase the cost of the system by 13%. © 2021 Hydrogen Energy Publications LLC | Elsevier Ltd | 3603199 | |

Aim of Study: To look for the presence of association between fatty liver disease (FLD) and erosive esophagitis in a sample of Iraqi patients. Materials and Methods: This was a cross-section- al study of asymptomatic patients did esophagogastrodu- odenoscopy (OGD) in two large gastroenterology centers between April 2019 and May 2020. Erosive esophagitis was classified according to Los Angeles (LA) classification and FLD was diagnosed by ultrasonography and fibroscan (Ultrasound Attenuation Parameter UAP). the anthropo- metric and laboratory data of the patients were analyzed with chi square test and phi coefficient. Results: In 110 patients, the total number of patients were classified ac- cording to OGD results into two groups, erosive esophagi- tis and non-erosive reflux disease (NERD). Again, the total number of patients classified into two groups, 40 (36.4%) patients found to have FLD were classified as fatty liver group and 70 (63.6%) patients found not to have FLD and classified as non-fatty liver disease group. The percentage of erosive esophagitis is higher in FLD group 21/40(52.5%) than in non-FLD group 19(47.5%), and the risk factors were investigated and correlated to each group by specific statistical equations. Conclusion: There is a significant as- sociation between FLD and erosive esophagitis and FLD is an independent risk factor for erosive esophagitis. © 2021, Venezuelan Society of Pharmacology and Clinical and Therapeutic Pharmacology.

Blue or violet nuclear stains have been created by combining an anthocyanin with iron or aluminum ions at low pH. Obtaining a pink or red cytoplasmic counterstain, however, has not been achieved previously, even with a red solution of anthocyanin, because the chemistry of the colorant does not allow bonding to cytoplasmic materials and collagen. We used two extracts from the petals of common mallow, Malva sylvestris, to create both a blue nuclear stain and a red counterstain. The two extracts contained two chemically distinct types of anthocyanins. The first extract contains vic-hydroxyls capable of complexing aluminum ions; its flavylium core is cationic. The second type lacks vic-hydroxyls on its core structure, but includes pendant glucosides that contain a malonic acid ester with a free carboxyl substituent. The precise identity of the first anthocyanin currently is unknown, but likely is one or more of the common anthocyanins such as cyanidin, delphinidin or petunidin, which complex readily with aluminum. The second anthocyanin is malonated malvidin, which does not complex with aluminum, but is anionic at the pH used here. The overall visual effect of applying the two anthocyanin extracts is remarkably similar to that of hemalum plus eosin. © 2021 The Biological Stain Commission. | Taylor and Francis Ltd. | 10520295 | |

These systems are implemented through medium communication link ranges for the purpose to overcome absorption and scattering as well as to meet the requirements of a wide variety of optical wireless applications. There are two ways for the application of the design mentioned above. The first way is the application of the two modulation schemes of technology that is Differential Phase Shift Keying (DPSK) modulation with Direct Detection (DD) and the DPSK modulation with Coherent Detection (CD). Both modulation schemes operate on Optical Orthogonal Frequency Division Multiplexing (OFDM) with different configurations of multi-input multi-output technology (MIMO). The second way is based on a mathematical model which has been proposed for this study. This mathematical model calculates optimal beacon period (BI) and optimal listen interval (LI) to preventing the overlapping of time between the signals and the decrease in the required power. By using different types of water samples, the simulation results revealed that the best performance of the UOWC system is from link range and the receiver is more sensitive. The simulation results are as follows: BER is equal to 10-5, BI is equal to 85ms, and LI is equal to 108ms. © 2021.

The tools for monitoring and optimizing queries typically used in modern DBMS were analyzed, and their shortcomings were identified. Subsequently, the relevance of new intelligent tools’ development for timely and reliable detection of resource-intensive queries to databases was distinctly justified. The study concluded a set of analysis of an extended statistical parameter which indicated to be of interest for identifying resource-intensive queries. The initial set of queries’ parameters reduced by two consecutive methods. Firstly, normalizing the set of indicators using a sigmoid function. Secondly, selecting a finite number of principal components based on the Cattell test. Whereas the clustering of a set of queries performed using self-organizing Kohonen maps.

Moreover, most of the cases appeared in 2018 (36%) and 2019 (29%), while the fewest cases appeared in 2017 (17%) and 2020 (18%). Further, this showed a significant difference. Therefore, the present survey detected the highest hrHPV16 infections in 2019 (78%) and 2020 (69%). Lowest infections (47%) were reported in the year 2017. Viral infections were common among young women and the infection rate decreased among older women. On the other hand, the distribution of HPV16 infections according to cervical cancer stages showed that the highest infections appeared in stage IV (70%) followed by III (68%), II (60%), and stage 0 (60%). hrHPV16 infections increased in Dhi-Qar province/Iraq during recent years especially in young women, and are associated with cervical cancer progression. © 2021, King Abdulaziz City for Science and Technology. | Springer Science and Business Media Deutschland GmbH | 21905509 | |

Recently, some studies have reported that people with O blood type are protected against COVID- 19, while people with A blood type are more susceptible to contract this disease. Here, we analysed data from 5668 COVID-19 patients along with the same number of control samples in a study population in Iraq. Our analysis confirms that people with O blood type are protected partially against COVID-19. Notably, we demonstrate that people with RhD- are more susceptible to contract COVID-19 than people with RhD+ blood type. The blood types are associated with some clinical symptoms such as headache and asthenia of COVID-19, but there is no association with other symptoms. There is no association between blood types and deaths among COVID-19 patients. This study suggests that in addition to ABO, RhD blood type influences the susceptibility to contract COVID-19. Overall, we conclude that susceptibility/protection against COVID-19 may not be determined based only on blood types among the global population as this might vary based on a number of other factors such as ethnicity, geographical locations, occupation and the level of exposure to infected people. © 2021 Majeed KR et al. | F1000 Research Ltd | 20461402 | |

In this context, researchers are urged and encouraged to research in various fields, to stop the spread of this deadly virus. To this end, we propose a systematic review that addresses the techniques and methods of artificial intelligence in diagnosing COVID-19 disease. The main aim of the current systematic review was to highlight the gaps and challenges within the academic literature of the disease COVID-19, which included the characteristics of the data, machine learning algorithms applied to the diagnosis of COVID-19, and using natural language processing (NLP)to reveal clinical data for COVID-19 disease.Seven reliable databases were used, namely Web of Science, ScienceDirect, IEEE Xplore, Scopus, PubMed, springer and google scholar, to obtain studies related to the specific topic many filtering and surveying stages were conducted consistent with the inclusion and exclusion criteria, to screen the acquired 1115 papers.We identified the bottleneck in explaining data as one of the major barriers to machine learning and NLP approaches. Supervised machine learning has been explored as an active method for diagnosing COVID-19 disease. Future studies in this area will benefit from alternatives like increasing the volume of data, using intelligence swarms to obtain accurate features, and using unsupervised learning that does not require explanatory data. Thus, this research supported us to get a more practical comprehension of the gaps and provide possible solutions for filling these gaps. © 2021.

In the recent researches, the performance analysis (PA) is generally determined for the reinforced concrete (RC) structures with the moment-resisting frame (MRF) and dual systems. The dual system comprises mainly the MRF with shear wall of building under construction, as well as the flat slab having chiefly the BD system. In this paper, the evaluation of values of the performance and failure analysis of RC structures using BD system are submitted. We recorded a maximum load of 6.48, maximum stress of 75.00, macimum strain of 7.80, with minimum force of 0.83, while minimum slab length of 9.62 and lastly the maximum slab span of 27 for our bubbledeck concrete slab experiment in comparison with reinforced concrete slab to get the best results. The obtained results indicate that the lateral strengths of buildings increase by increasing the span length to story height ratio. Besides, the variations of the span length and the number of the story have more effects than the variation of the usage category buildings on the performance of structures. Furthermore, the span length has more effect than the number of stories in determining performance in an MRF. We observed that the bubbledeck concrete slabs are more lightweight and resistant in comparison with reinforced concrete. © 2021.

ZnONPs were formed by dissolving of OLE in zinc oxide solution with adjusted pH to 12. Zinc acetate dehydrate reduced to ZnONPs during mixing with OLE associated with change of the color solution from white to pale yellow color within a few minutes. The synthesized OLEZnONPs were separated by centrifugation (4000rpm/5min), then characterized by Fourier Transmission Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD) and Field emission-Scanning Electron Microscopy (FE-SEM) methods. The results of FT-IR showed that the functional group related to Zn-O at (433.98 to 416.67 cm_1), whereas X-RD at 2 theta diagnose the type of oxide formation as ZnO and determined particle size in range (20 – 30 nm). Besides, SEM image was showed the presence of hexagonal shape of ZnO nanoparticles (42.87nm). Therefore, the biogenic synthesis of zinc oxide nanoparticles using Olea Europaea leaves was simple, low coast, can be an alternative to chemical synthesis and the possibility of using in biomedicine field © 2021 | University of Baghdad, College of Agriculture | 750530 | |

Previous research has shown that the chloride and moisture content of concrete, corrosion state, and depth of reflecting objects (e.g., steel reinforcing bars) have some impact on the strength of GPR signals. What is not yet clear, however, is to what extent these factors can affect GPR response. This research has sought to quantitatively determine the effects of these factors on the attenuation and the resulting response of GPR signals reflected from reinforcing bars in concrete. The effects of these factors were experimentally demonstrated by analyzing data from four reinforced concrete slabs. Analysis of the processed data showed that attenuation was highly attributed to the depth of the reinforcing bars as compared to the concrete chloride and moisture content, where the amplitude of the reflected signals decreased by 4.5dB for every 25 mm increase in depth as compared to about 1.0 dB reduction in signal amplitude due to the presence of chloride and moisture. Corrosion of reinforcement bars, on the other hand, slightly increased the amplitude of the reflected signals by 1.0 dB. © 2021 Praise Worthy Prize S.r.l.-All rights reserved. | Praise Worthy Prize S.r.l | 20369913 | |

Therefore, such a condition resulted in developing novel anti-microbial agents. Hence, a lot of researchers specially investigated the new 2,5-disubstituted-1,3,4-thiadiazole derivatives, which exhibit alternative biological activities. Then, new transitional metal (Fe(III), Ni(II) as well as Cu(II) complexes of ligand 2,5-bis[(2E)-2-(2-bromobenzylidene)hydrazinyl]-1,3,4-thiadiazole were prepared. All the prepared complexes were diagnosed by IR, elemental analyses, H1-NMR and mass spectral. The electronic behavior of their link data has been confirmed.It was concluded that ligand had coordination via nitrogen (N) and (NH) atoms, which has been noted in during the study for each complex. Ligand coordinated through the [15NH] and the nitrogen atom of Schiff base [N3]. This view is more supported by a band’s appearance returned to the metal–nitrogen stretching vibration at 540–547 cm–1 in the complexes. With regard to the findings obtained, we recommended the tetrahedral geometry for Cu(II) and Ni(II) complexes, whereas Fe(III) complexes were presented octahedral geometrics. All the synthesized complexes have been screened for anti-bacterial by using the spread method and measurement inhibition zone with E-coli and staph aureus (DMSO). © 2021, Dr. Yashwant Research Labs Pvt.

This drug has predominantly hydrophobic property causing a low solubility and low bioavailability. Surface solid dispersions (SSD) is an effective technique for improving the solubility and dissolution rate of poorly soluble drugs by using hydrophilic-water insoluble carriers. The present study aims to enhance the solubility and dissolution rate of EBS by using SSD technique. Avicel® PH101, Avicel® PH 102, croscarmellose sodium(CCS) and sodium starch glycolate (SSG) were used as water insoluble hydrophilic carriers. The SSD formulations of EBS were prepared by the solvent evaporation method in different drug: Carrier weight ratios, then evaluated for their percentage yield, drug content, water solubility, release in 0.1 N HCl, Powder X-Ray Diffraction (PXRD) in addition to Fourier Transform Infrared Spectroscopy (FTIR) for the determination the drug-carrier interaction. Most of the prepared SSD formulas showed improvement of drug solubility. The best result was obtained with formula SSD16 (EBS: CCS 1:15) that showed high percentage yield (98.5%), high drug content (98.39%) and 8.2fold increase in solubility compared to solubility of pure drug with improved dissolution rate. The drug was converted to amorphous form without chemical interaction with the carrier. So, it can be concluded that the solubility and the dissolution rate of EBS were successfully enhanced by SSD technique prepared by solvent evaporation method using hydrophilic-water insoluble carriers. © 2021 University of Baghdad - College of Pharmacy.

Basically, this model is used for five main purposes: to test the prediction accuracy (the diametrical error in dimensions, deviation of the shape as well as in the mutual arrangement of surfaces, treated surface taking into account the variables of process conditions, degree of blunting of the grinding wheel and initial radial run-out, etc.). As a result, in multi-stages, the quality parameters of the model processing differ significantly from the quality parameters with those of another surface being treated. This article describes a methodology for optimizing operational parameters at the stage of cutting during cylindrical external grinding with radial and axial in-feed process of a reversible stage. The model approach can be successfully applied to designing and optimization of different stages in grinding cycles with radial and axial in-feed at CNC. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. | Springer Science and Business Media Deutschland GmbH | 21954356 | |

Collaborative filtering is the most commonly used method for recommendation systems. In a collaborative filtering algorithm, the similarity factor employed in discovering the users with the same actions with respect to the chosen products is one of the key components of recommendations without considering any other information related to the recommender system entity. In this paper, we present a new correlation and slope-based neighbor selection model which concentrates on measuring the importance effecting of entities on each other. The proposed model picks the similarity in the importance of the correlated entities and takes it into account. Additionally, we suggest a new rating prediction model based on the first available rating from the nearest neighbors. We tested other new models in addition to our proposed model. The experiments are performed on three real datasets to test our model accuracy and compare with many state-of-the-art similarity measures accuracy. Experimental outcome confirms that the proposed model surpasses the recommendations accuracy of the previous methods. The results authenticate the effect of using the recommendation system entities information like the degree of importance to identify suitable neighborhoods and obtain a fitted recommendation system. Therefore, we can consider that our proposal is an effective method to select the nearest neighbors successfully and support the recommendation process carefully. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 23673370 | |

In such networks, most of the nodes possess the same few lowest degrees (mostly degrees of 1, 2, 3), and the number of nodes reduces exponentially as we increase the degree. This creates redundant structures in the network where many nodes have identical connections. In this paper, we transform such complex networks into their intrinsic and simplified structure such that the redundant nodes and connections are removed intelligently while preserving their overall structural features and complexity. A network intrinsic model is proposed to group similar topological structures (nodes and edges) into single nodes that preserves the network features. We implemented our network intrinsic model on several different types of complex networks, and our results demonstrate different degrees of network complexity reduction depending on the size and topology of the networks. The proposed model can be used to minimize the overhead of processing complex networks with no loss of topology or data and thus reduces the computing time of different complex networks algorithms related to its topology besides having potential applications in problems related to network alignment. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 23673370 | |

A subset D−1 of V −D is an inverse triple effect dominating set if every v ∈ D−1 dominates exactly three vertices of V −D−1. The inverse triple effect domination number γte−1(G) is the minimum cardinality over all inverse triple effect dominating sets in G. Some results and properties on γte−1(G) are given and proved. Under any conditions the graph satisfies γte(G) + γte−1(G) = n is studied. Lower and upper bounds for the size of a graph that has γte−1(G) are putted in two cases when D−1 = V − D and when D−1 ≠ V − D. Which properties of a vertex to be belongs to D−1 or out of it are discussed. Then, γte−1(G) is evaluated and proved for several graphs. © 2021, Semnan University, Center of Excellence in Nonlinear Analysis and Applications.

Experiments are conducted within a turbulent flow for Reynolds numbers values varied from 10000 to 35000, pitch ratio equal to 5 and height ratio of 0.33. The numerical study carried out using ANSYS FlU- ENT17.2. The turbulence is modeled by using k-ɛ model. The results showed that the case of intermittent ribs provide the highest over performance factor while the continuous ribs indicate less overall performance factor among the considered cases. In addition, the results show that the highest values of the friction factor are marked from the case of intermittent ribs and then the case of intermittent-contin- uous-intermittent ribs followed by continuous rib case. The continuous rib case showed the lowest friction factor. The experimental results showed a good agree- ment with the computational results. © 2021 Society of Thermal Engineers of Serbia Published by the Vinča Institute of Nuclear Sciences, Belgrade, Serbia.

In this paper, the non-destructive testing (NDT) and structural health monitoring (SHM) techniques were used to visualize and quantify three different sizes of simulated delaminations inserted in a cross-ply CFRP plate. An experiment of using RollerFORM and OmniScan equipment was conducted to verify and visualize three simulated delaminations. The guided waves-based developed imaging methods with a sufficient network of piezoelectric wafer active sensors was performed to quantify the shape and size of simulated delaminations. The group-velocity directivity plots were determined based on the mechanical properties of the interested specimen to estimate the group velocity values of incident and scattered waves. A simple method was developed to estimate the group velocity values of incident and scattered waves at each point of interested area based on the group-velocity directivity plots of propagating Lamb modes and the coordinates of transmitter and receiver transducers. The results demonstrate the capability of the developed imaging method for quantifying the size and shape of interested delaminations. The interaction of guided waves with delaminations were visualized experimentally using scanning laser Doppler vibrometer (SLDV). The effect of the delamination severity on the trapped waves generated over the delamination region was studied experimentally. It was found that delamination size can affect trapped waves. The large delamination has strong trapped waves compared with the small delamination which has weak trapped waves. The wavenumber analysis was conducted for the experimental wavefield data to study the effect of delamination severity on wavenumber components and to identify the delaminations. The result showed that new wavenumber components can affected by the delamination severity. The significant new wavenumber components due to strong trapped waves can be observed for the large delamination case. © 2021 SPIE. All rights reserved. | SPIE | 0277786X | |

Medicine College, University of Thi-Qar, Thi-Qar, Iraq; Kang, S.W., Poultry Science (POSC), University of Arkansas, Fayetteville, AR, United States; Kuenzel, W.J., Poultry Science (POSC), University of Arkansas, Fayetteville, AR, United States | Corticotropin releasing hormone (CRH) neurons located in the nucleus of hippocampal commissure (NHpC) have been proposed to be involved in the avian neuroendocrine regulation of stress and appeared to respond prior to CRH neurons in the hypothalamic paraventricular nucleus (PVN) when food deprivation stress was applied. Since the response of the NHpC was rapid and short-lived, was it regulated differentially from CRH neurons in the PVN? We, therefore, applied immobilization stress to test whether the NHpC response was stressor specific. Gene expression of CRH and stress-related genes in the NHpC, PVN, anterior pituitary (APit) as well as plasma corticosterone (CORT) were determined. Furthermore, brain derived neurotrophic factor (BDNF) and glucocorticoid receptor (GR) were examined regarding their possible roles in the regulation of CRH neurons. Data showed that rapid activation of CRH mRNA in the NHpC occurred and preceded a slower gene activation in the PVN, upregulation of proopiomelanocortin (POMC) transcripts in the APit and significant increases of CORT concentrations. Results suggested BDNF’s role in negative feedback between CRH and CRHR1 in the NHpC and positive feedback between CRH and CRHR1 in the PVN. In the APit, V1bR activation appeared responsible for sustaining CORT release when stress persisted. Overall, data suggest that the NHpC functions as part of the HPA axis of birds and perhaps a comparable extra-hypothalamic structure occurs in other vertebrates.Lay Summary The nucleus of the hippocampal commissure, a structure outside of the hypothalamus, shows rapidly increased neural gene expression that appears to contribute to the early activation of the traditional hypothalamic-pituitary-adrenal (HPA) axis responsible for the production of stress hormones. © 2021 Informa UK Limited, trading as Taylor & Francis Group. | Taylor and Francis Ltd. | 10253890 | |

Their model has been used through several studies in different countries. The relationships between the success model constructs have varying outcomes in prior studies. Therefore, there is a need to conduct a review of previous studies on the IS success model with different contexts. In this paper, we conducted a meta-analysis review among empirical studies in terms of country, year and results in each study. By aggregating the results of 52 empirical studies that tested relationships within the IS success model at the individual level of analysis. Findings showed that different findings occur in various countries with different cultural contexts at the same theory and constructs. Therefore, due to the inconsistency of the findings among the constructs’ relationships of the D&M success model, it is necessary to examine the constructs in different environments, such as unstable environments (conflicts and violence). © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 21945357 | |

The study was carried out to found any significant monocyte level changes in COVID-19 and its relation to diagnostic usefulness and expectation of adverse outcomes. A sample of 100 patients was recruited into the analysis; all with diagnosis compatible with pneumonia underwent care inwards of Al-Hussein Hospital for isola-tion; 50 participators with COVID-19 as cases and 50 participators with influenza A elected control. The diagnosis was suggested by clinical and radiological attributes and verified by polymerase chain reaction. Monocytes total and laboratory analysis of inflammatory indices and organ vitality were achieved for all participants. The mean age was 64.4, includ-ing 56 males and 44 females. 66% of cases were monocy-topenic, 34% were non-monocytopenic. 12% of control were monocytopenic while 88% were non-monocytopenic with significant difference (P value=0.001). Forty-five participants were critical while 55 were non-critical, 37 COVID-19, and eight controls were critical and admitted to the ICU. Forty-one participants died, 35 from the COVID-19 category and six from controls. 30 of COVID-19 who were critical in ICU were monocytopenic (all died), three were non-monocytic (only one died) and 4 had monocytosis (all died), 6 of control who were critical in ICU were monocytopenic (all died), 2 had normal count (all survived) and no one had monocyto-penia (Odd ratio=1.200). Deviation in monocyte count from the norm is a valuable discriminator for the diagnosis of CO-VID-19 and a suitable anticipator across all spectrums for its adverse consequences. © 2021, Venezuelan Society of Pharmacology and Clinical and Therapeutic Pharmacology.

The small intersection graph G(M) of a semimodule M is an undirected simple graph with all non-small proper subsemimodules of M as vertices and two distinct vertices N and L are adjacent if and only if N ∩ L is not small in M. In this paper, we investigate the fundamental properties of these graphs to relate the combinatorial properties of G(M) to the algebraic properties of the R-semimodule M. We determine the diameter and the girth of G(M). Moreover, we study cut vertex, clique number, domination number and independence number of the graph G(M). It is shown that the independence number of small graph is equal to the number of its maximal subsemimodules. © 2021, Semnan University, Center of Excellence in Nonlinear Analysis and Applications.

The modified engine was designed to produce the new technology for variable compression ratio engine using variable piston's height. Where the piston consists of two parts, (upper part and lower part), the height of piston varies by press hydraulic between these parts via pipe within cylinder head. The MATLAB program was used to determine the thermal characteristic for the studied engines (Otto Cycle Engine, Pre-Variable Compression Ratio Engine, Instantaneous Variable Compression Ratio Engine, Miller Cycle Engine with late valve close, Pre-Variable Compression Ratio Miller Cycle Engine with late valve close and Instantaneous Variable Compression Ratio Miller Cycle Engine with late valve close) with/without turbocharger. The results showed the Instantaneous Variable Compression Ratio Engine is the highest power when used without turbocharger. The Instantaneous Variable Compression Ratio Miller Cycle Engine with late valve close has the highest power when it used with turbocharger in maximum limit of compression ratio (1:12). Thus, the modified engine can be used in new technology of variable compression ratio engines. © 2021 Zibeline International Publishing Sdn. Bhd..

This paper will be studying the pressure and velocity distributions on the surface of the body of a passenger car (Chrysler300s) under the effect of wind at various angles (0º,35º, 90º, and 125º) when tracking another passenger car, as well as when tracking an SUV (Mercedes G-Class) car with three distances (5m,10m, and 15m) when the vehicle speed was 120 km / h and the air speed 80 km / h. Using CFX Ansys R (19.0) simulation program. The results showed that the largest value of the reaction force of the front tires is on the front right tire (Tire FR) of the passenger car at an angle of 35 o and a distance of 15 meters between the two tandem cars. The drag force of the two tandem cars decreases as the distance between them decreases and the drag force on the rear car is less than the front car because this may refer to that design of the Chrysler class does not generate significant wakes. © 2021 Zibeline International Publishing Sdn.

An 800-watt Extraction Water Machine (EWM) is fabricated and operates on the well-known “vapor compression cycle” to extract water from the air in an area that has low relative humidity. Three options have been studied experimentally: dehumidification directly from atmospheric air with dry mode (option I); humidification-dehumidification with dry mode (option II); humidification-dehumidification with cooling mode (option III) during different days of May in Nasiriya city, Iraq. As temperature and relative humidity are the two main factors that control condensation and the amount of condensate, in addition to cooling capacity, therefore the aim of the study to determine the optimum temperature and relative humidity values at which the maximum amount of condensed water is obtained and the operation mode. mathematical models for hourly condensation rate was formulated by doing quadratic regression for experimental results and use it in non dominated sorting genetic algorithm NSGA-II and modeFRONTIER software to access solutions near the interface of the Pareto for the optimal operation of EWM to maximize water harvesting for each option. The results showed the ideal climatic conditions for optimal water production for each option. Whereas the optimal water production was 0.7622 L/h during climatic conditions 23 °C, 47 % RH in option I and 1.463 L/h at 33.6 °C and 65% RH in option II while was 1.672 L/h at 23.58 °C, 62 % RH per hour in option III It's clear to notice that the third operating strategy gave the best results. © 2021 Zibeline International Publishing Sdn.

The full vehicle model with nonlinear behaviour for springs and dampers is used as a case study when subjected to random excitations. The dynamic performance of the hydraulic-harvester suspension was compared with the passive, full-active hydraulic and full-active electric suspensions system using MATLAB/Simulink software. The PID control strategy is used to control the spool valves of the hydraulic-harvester suspensions for maintaining the dynamic performance of hydraulic-active suspensions systems to harvest the kinetic energy of road ripples.

Thus, miniaturization concept has been used in the design and synthesis of the fabricated materials and devices based on nano-dimension. However, reducing the used materials would affects the overall performance of the devices and new building blocks materials are needed to pass the performance capacity limits of current silicon-based materials. Quantum Dots DQs have been introduced and attracted much attention among researchers because of their unique characteristics that are necessary for many potential applications by using nano-dimensions structures. These properties include size-tunable optical and other electronic characteristics that are not found in the current bulk materials. Although there has been interested QDs experimental studied that have been already carried out, different theoretical efforts must be introduced in order to provide good understanding of the possible and different QDs applications. In this work, therefore, optoelectronic properties of Double Quantum Dots DQDs system were studied theoretically to provide important information about the possibility of using this system in photoelectric applications. A tight-binding framework was adopted to describe the system, and all the calculations were carried out based on the steady state formalism. The proposed DQD structure was connected to metallic leads and studied to investigate the QD size dependent. The transmission calculation presented first through the electron transport mechanism. Tunneling current and conductance were then presented to provide general understanding about the behavior of the proposed system. A correlation of transmission, current and conductance results with QD radius R, incident photon energy Eph, Temperature and bias voltage have been identified. Therefore, this correlation is strongly supporting the proposal of using DQD system in fabricating nano-scale photovoltaic devices, particularly, solar cells. © 2021, Anka Publishers.

In order to identify the challenges of the transfer of blocks, this study focuses on a comprehensive study of the problems arising from the transmission of information in the form of separate data blocks and of the influence of the number of unauthorized blocks on the probability of collisions. In this study, we describe a method for distinguishing legal software data from data sent by unauthorized software sources. The analysis of the methods of reducing the probability of errors occurring at the receiver is done through the use of a buffer to store and a set of mathematical equations. The same way the analysis of the methods of possibility of reducing the reception of the unauthorized blocks when receiving individual blocks of information is done as well.

Consequently, there are a significant progress in the numerous fabrication of this material. Furthermore, many other supreme characteristics, whole make it quite attractive for many applications. In the present research, it is illustrated the electronic properties of grapheme nanoribbons with and without of impurity. These properties depend critically on a number and type of impurity are founded in the ribbon (the width and the nature of the ribbon edge are constants). All the computations have been achieved by the density functional theory within the 6-31G basis set B3LYP level throughout Gaussian 09 software. Finally, we calculate electronic properties for paradigms such as geometrical structure, HOMO, LUMO, energy gap, ionization potential, electron affinity, as well as electronegativity, hardness, softness, dipole moment and finally the polarizability. Herein, the both 8Al–GNR and 8P–GNR are the highest reactivity structures among all specimens because they have the highest values of average polarizabilitiy (1046.008 and 1035.1623 a.u.) respectively. Consequently, the high values of polarizibility show that the paradigm has very useful linear and nonlinear optical implementation. Interestingly, the band gap was computed of pure GNRs and found equal to 0.51 eV. Whereas, the value of doping in GNR can be noted that the band gaps is sometimes shrinks and other times expands. This values are limited between 0.285 to 1.158 eV) for paradigms 2Al–GNR and 4P–GNR respectively. Finally, the band gaps cover a wide range of values and thus allows it to be used widespread in electronic applications. © 2021, Pleiades Publishing, Ltd. | Pleiades journals | 19907931 | |

Triangular twisted tube with (1m) length and (0.03m) diameter was tested for different twist ratios (5, 10 and 20) and Reynolds numbers (Re=5000 to 25000) consequently. The governing equations used in the analysis of the flow field and heat transfer are the momentum, continuity and energy equations. The numerical solution for turbulent flow field and heat transfer is governed by the techniques of a finite volume method with ANSYS Fluent 17.1. The computational data indicated that the twisted tube showed increasing in heat transfer as compared with a plain tube. The twisted ratio was the main affecting parameter for heat transfer improvement and friction losses. The numerical results are compared with published results and an acceptable agreement is achieved. ©2006-2021 Asian Research Publishing Network (ARPN).

Damages in composite materials may exist as visible or non-visible with different configurations and identities. Thus, investigation of damages existence in composite materials has to have prior attention to avoid the failure of structures. The current work investigates the damping response offered by a damaged fiber-reinforced polymer plate. The plate is put under three different conditions regarding the damage existence. The focus is to measure the loss factor in all cases and determine whether there is a difference among them to prove damage presence in the composite part. The loss factor is experimentally measured by measuring the reverberation time RT60. The resulting data of loss factors show a well-distinguished difference that might lead to predicted damages and to do a more expanded analysis of this issue. © 2021 Growing Science Ltd. | Growing Science | 22918744 | |

One of the FLPs is the hospital facility layout problem that aims to place comprehensive clinics, laboratories, and radiology units within predefined boundaries in a way that minimizes the cost of movement of patients and healthcare personnel. We are going to develop a hybrid method based on discrete differential evolution (DDE) algorithm for solving the QAP. In the existing DDE algorithms, certain issues such as premature convergence, stagnation, and exploitation mechanism have not been properly addressed. In this study, we first aim to discover the issues that make the current problem worse and to identify the best solution to the problem, and then we propose to develop a hybrid algorithm (HDDETS) by combining the DDE and tabu search (TS) algorithms to enhance the exploitation mechanism in the DDE algorithm. Then, the performance of the proposed HDDETS algorithm is evaluated by implementing on the benchmark instances from the QAPLIB website and by comparing with DDE and TS algorithms on the benchmark instances. It is found that the HDDETS algorithm has better performance than both the DDE and TS algorithms where the HDDETS has obtained 42 optimal and best-known solutions from 56 instances, while the DDE and TS algorithms have obtained 15 and 18 optimal and best-known solutions out of 56 instances, respectively. Finally, we propose to apply the proposed algorithm to find the optimal distributions of the advisory clinics inside the Azadi Hospital in Iraq that minimizes the total travel distance for patients when they move among these clinics. Our application shows that the proposed algorithm could find the best distribution of the hospital's rooms, which are modeled as a QAP, with reduced total distance traveled by the patients. © 2021 Asaad Shakir Hameed et al. | Hindawi Limited | 1024123X | |

The working fluid used in this paper is a hybrid suspension consisting of nanoparticles and MEPCM particles, in which the particles are suspended in pure water as a base fluid. Two types of hybrid suspension are used (Al2O3 +MEPCM and Cu + MEPCM), and the hydrodynamic and thermal characteristics of these suspensions flowing in a CFMCHE are numerically investigated. The results indicated that using hybrid suspension with high flow velocities improves the performance of the microchannel heat exchanger while resulting in a noticeable increase in pressure drop. Thereupon, it causes a decrease in the performance index. Moreover, it was found that the increment of the nanoparticles' concentration can rise the low thermal conductivity of the MEPCM slurry, but it also leads to a noticeable increase in pressure drop. Furthermore, it was found that as the thermal conductivity of Cu is higher than that for Al2O3, the enhancement in heat transfer is higher in case of adding Cu particles compared with Al2O3 particles. Therefore, the effectiveness of these materials depends strongly on the application at which CFMCHE is employed. © 2021 Mushtaq I. Hasan et al. | Hindawi Limited | 1024123X | |

It is estimated that nearly 90% of the existing timber sleepers will need replacement by 2030. Recently, increasing costs, declining quality, hardwood timber scarcity and environmental sensitivity has challenged the continuing use of timber sleepers in rail track. Consequently, the Australian rail industry is now looking an alternative materials to replace existing timber sleepers and it is projected that in next five years they will move from a traditional timber-based system (15 years lifespan) to that of an engineered composites system (at least 50 years lifespan). This paper critically reviewed the recent development of composite sleepers, identified the potential issues and provided guidelines to overcome the challenges. © Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 23662557 | |

In this study, a geological model is built for Nahr Umr Formation based on data of 11 wells (SU-2, SU-3, SU-4, SU-5, SU-6, SU-7, SU-9, SU-10, SU-11, SU-13, and SU-14), including the location of wells, well tops, also contour map of the Nahr Umr Formation in Subba oil field is utilized. The structural model is constructed for the Nahr Umr Formation, which consists of two domes. The formation is composed of sandstone mainly interbedded with shale. The formation is divided into four units (B1, B2, C1, and C2) depending on well log data, each unit is divided into layers for getting better distribution of petrophysical properties, where unit B2 is divided to the number of layers is higher than other units due to its heterogeneity. Variogram is used as a geostatistical method to predict the petrophysical properties at unsampled locations, experimental variogram is calculated from well log data in a horizontal and vertical direction. The spherical variogram model shows a good fitting with the experimental variogram. Sequential Gaussian algorithm is used in distribution of petrophysical properties in a geological model which shows good petrophysical properties in unit B2 and unit B1, while units C1 and C2 are highly saturated with water. © 2021, Union of Iraqi Geoogists.

This family is called Weibull Lindley general family of distributions (WLGFD). Several properties of WLGFD are derived including the PDF, CDF, hazard rate function, reversed hazard function, odd function, and quartile function. On this approach, we derive two distributions: The Weibull Lindley Uniform distribution (WLUD) and Weibull Lindley Exponential distribution (WLED). The PDF, CDF, moment generating function, hazard rate, reversed hazard function, odd function, quartile function and moments are proved of the WLUD and WLED. An estimation procedure by the method of maximum likelihood and a simulation are studied of WLUD and WLED respectively. finally, we give graph of PDF, CDF, mean squared error and bias at different values of parameters of WLUD and WLED. © CSP - Cambridge, UK; I&S - Florida, USA, 2021 | Cambridge Scientific Publishers | 20413165 | |

Previous studies showed that, when used in combination, MK and polymers can complement each other, and enhance further the mechanical and durability properties of concrete, which were not improved by one another separately. To have a deep observation and understanding of the mechanism of concretes modified with various combinations of MK and polymers, this study investigates the changes in the microstructures based on SEM combined with CT scan analysis scan technologies. The findings show that the microstructure of the pore of hardened concrete modified with combined MK and hybrid polymers is significantly improved compared to samples with MK or polymers alone. This indicates that this approach can be effectively used to provide additional proof on the strength and porosity properties of high-performance concrete. © 2021.

For computing the maximum likelihood estimators with partly interval censored data, three methods are used, namely, Newton-Raphson, Expectation-Maximization and Monte-Carlo Expectation-Maximization algorithms. The standard errors of the estimates are computed using the observed information matrix. Also, two types of confidence intervals are constructed using the Wald method and the nonparametric percentile bootstrap confidence intervals. For computing the Bayes estimators, three methods viz Lindley's approximation, Tierney-Kadane approximation and importance sampling methods are used. Highest posterior density (HPD) credible intervals of the two parameters are constructed using importance sampling technique. Monte-Carlo simulation experiments are conducted to investigate the performance of the proposed methods. Finally, the methods are illustrated by using two real data sets, one is related with diabetic patients data set and the other is related to HIV infection data set. © 2021 Informa UK Limited, trading as Taylor & Francis Group. | Taylor and Francis Ltd. | 949655 | |

The result showed that low and high root zone heating decreased leaf area, total sugar and phenol content compared to root zone temperature 25°C (optimum), while main branches number, pH, E.C. and anthocyanin of fruit,increased at high root zone temperature compared to low root zone temperature. Flavonoid increased under the root zone temperature of 20°C in comparison with temperatures 25 and 30°C, and stem diameter was not affected by root zone heating. Furthermore, salt stress at the level of 3 ds.m-1 increased stem diameter, total sugar, pH and EC of fruit, leaf area and phenol content, whereas salt stress at a high level (6 ds.m-1) increased flavonoid content. Besides, anthocyanin content decreased in control and salt stress at 6 ds.m-1 when compared to salt stress at 3 ds.m-1. © 2021, University of Basrah, College of Agriculture.

Each player chooses one of two strategies with probabilities x and 1-x, where the subjective players bias their choices of the probabilities to be w(x) and w(1-x) to reflect the probability weighting effect of PT. We derive the conditions to achieve a locally asymptotically stable Nash equilibrium (NE) and the necessary conditions to achieve an evolutionary stable strategy (ESS). We illustrate these results through a simple random access channel game. We find that players' behavior is affected by the total number of players as well as the number of each type of players (objective or subjective). We show that increasing the number of interacting players induces an aggressive transmission strategy and the behavior becomes similar for both types of players. Moreover, we let the objective and subjective players adjust their transmission under throughput rewards, delay penalties, and energy costs. The EUT players' throughput is higher than the PT players' throughput for a small number of interacting players and equal to if the number of interacting players increases. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

The investigative resolution is availed and the behaviour of the heat transfer is inspected under a persistent thermic flux frontier condition. It has been demonstrated that the Nu stubbornly relies upon the power-law index n value. The Nu (Nusselt number) recognizably gets reduced in a range of n from 0 to 0.1. Nonetheless, for n greater than 0.5, there is a monotonic decrement in the Nu with the incremental n, and for n greater than 20, values of the Nu have approached a constant. © 2021, Journal of Thermal Engineering.

The perturbation in behavior of the QDLED can be significantly increased by optoelectronic feedback. Changing the coupling strength between the transmitter and receiver in unidirectional coupling greatly contributes to creating a state of total synchronization between the two systems. Furthermore, the proposed communication model was successful by effectively receiving messages. © 2021, Anka Publishers. All rights reserved. | Anka Publishers | 13035150 | |

It aims to unveil the ideological discursive formation of Brexit after the referendum, and to investigate the way May squares the rhetoric to persuade the general public and the British/European political Elites to deliver the Brexit deal, though she campaigned pro-European Britain. I conduct a corpus-assisted discourse study approach, using discourse analysis methods and corpus linguistics tools for a case study of a purpose-built corpus of the Prime Minister speeches (2016-2019). The analysis revealed that the Brexit representation eschewed any identification with ‘Europe’ and boosted Eurosceptic sentiments by (1) rationalizing the decision to leave the European Union; (2) proposing a better future after Brexit; (3) appealing to the British people’s emotion to support the Brexit deal. © 2021 Masaryk University.

As a simple extract roselle acts as a general red counterstain, but when treated with an oxidant and metallic mordant it functions as a useful blue nuclear-selective stain. In the past 40 years it has been assumed that oxidation is necessary when preparing a stain from roselle, as of course it is for the related flavonoid dyes hematoxylin and brazilin. However, the chemistry of roselle argues against this. Roselle is a mixture of four closely related compounds: delphinidin 3-sambubioside and cyanidin 3-sambubioside, delphinidin 3-glucoside and cyanidin 3-glucoside. Each of these in turn can exist in 8 different configurations in a complex state of equilibrium largely dependent upon pH. Of these compounds, only three are colored. In plants, and in their complex extracts, formation of these colorless compounds is inhibited by the presence of other colorless aromatic molecules, a stabilizing process termed co-pigmentation. The color of such extracts may be red in the acid range and blue or violet above neutrality. Complexation (chelation) with metal cations occurs above pH 2.8 or 3.0, depending upon the concentration of the metal. Prior oxidation is not needed for such chelation to occur. With Al3+ the resulting metal complex, which we term rosalum, is violet or blue. Following spectrophotometric investigation of this complexation, we were able to formulate a nuclear-selective violet/blue stain without the use of an oxidant. © 2021 The Biological Stain Commission. | Taylor and Francis Ltd. | 10520295 | |

Let G be a finite graph, undirected, simple and has no isolated vertex, a set D of V (G) is said an arrow dominating set if |N(w) ∩ (V − D)| = i and |N(w) ∩ D| ≥ j for every w ∈ D such that i and j are two non-equal positive integers. The arrow domination number γar (G) is the minimum cardinality over all arrow dominating sets in G. Essential properties and bounds of arrow domination and its inverse when i = 1 and j = 2 are proved. Then, arrow domination number is discussed for several standard graphs and other graphs that formed by join and corona operations. © 2021, Semnan University, Center of Excellence in Nonlinear Analysis and Applications.

Results showed a decrease in the concentration of chlorophyll where the lowest concentration was recorded during the period (2.5) minutes for both algae and reached 0.3 mg l-1 for cladophora and 0.21 mg l-1 for spirogyra. There was increase in the concentration of carotenoids in the cells -1 -1 in both species of algae being 0.037 and 0.18 mg-l, respectively at the period of 2.5 minutes. The resistance of Cladophora compared to Spirogyera for the studied radiation pattern can be attributed to genetic differences between algae. © 2020 Ecological Society of India.

The P-IBI is composed from seven metrics: Species Richness Index (SRI), Density of Phytoplankton and total biomass of phytoplankton and Relative Abundance (RA) for blue-green Algae, Green Algae, Bacillariophyceae and Euglenaphyceae Algae. The average P-IBI values fell within the range of (45.09-52.4). Therefore, water throughout the entire study area was characterized by the equally "poor" quality. Negative points of anthropogenic impact detected at the stations are: Above the city of Rostov-on-Don (1 km, higher duct Aksai) was 38.57 in June, the lower inflow of the Temernik river which was 38.57- 41.42 in summer and below the spillway was 38.57 -34.28 in August. At these stations, samples with P-IBI values more than 56, characterizing water quality as "Fair", were not found in any of the observations. The negative effect on the water at the stations may be due to the influence of the closely located Aksai city and the impact of the Temernik River. In Russia P-IBI have not been used yet, so this study can be considered as the first study that's conducted to assess the environmental status of the Don River by using the phytoplankton index of Biological Integrity and has developed scoring criteria of the Don River (P-IBI) and other watercourses of the south of Russia. The continuous monitoring relaying on the selection of the most suitable metrics score is recommended. © 2021 University of Baghdad. All rights reserved. | University of Baghdad | 20788665 | |

The experiment is applied by using factorial experiments according to Randomized complete block design with three replications. The treatments included four salt concentrations (0, 2, 4, and 6) ds.m-1 and four Herbal-marine concentrations (0, 0.5, 0.75, 1) g.l-1. The salinity caused a significant increase in the leaves content of proline in the two concentrations (0.75 and 1) g.l-1. As for the number of seeds per pod, there was a significant decrease at the level of (0.75) g.l-1 and there was a significant effect on the seeds yield per plant and productivity of total seeds. Thus, there was a significant decrease in these two characteristics when the salt concentrations increased. The salinity did not significantly affect the protein. At the same time, it caused a significant decrease in the percentage of dry matter in the seeds. Herbal-marine extract caused a significant increase in proline and in the yield characteristics, so it had a significant effect on the number of seeds per pod. Also, it had caused a significant increase in the seeds yield per plant and the total yield of soft seeds, and the extract had a significant effect on the percentage of dry matter and the percentage of protein in the seeds. The interaction showed a significant effect on most of the studied traits such as proline, seeds number per pods, and seeds yield per plant. Thus, it gave a significant increase in the total yield of fresh seeds. The interaction also had a significant effect on the percentage of dry matter in pods and protein. © 2020 DAV College.

An accurate approach is provided to classify NDD patients using gait dynamics. It is developed to extract the most representative features by employing Transient artifact reduction (TAR) and statistical feature extraction method (SM). These features are utilized as inputs for three machine learning methods: K nearest neighbors (k-NN), support vector machine (SVM) and linear discrimination (LD), to evaluate the performance of the proposed approach. Conducting experiments on two databases revealed that the proposed method based on k-NN classifier yielded highest performance among other classifiers. It produced the best performance comparing to TAR-SM with SVM and LD classifiers for both databases. It had 100% overall performance of ACC, PPV and NPV. Comparing the overall performance of TAR-SM based on k-NN classifier with other existing methods showed the efficiency of the proposed method. It gave a 100% accuracy while the highest accuracy achieved in the literature was 96.8%.

This system becomes after including the wetting layer (WL) as a ladder-plus-Y- system. The results show that the high probe field under high SGC can give good entanglement between states of the DQD system. Under the high SGC component, the optical pump was more efficient than the probe signal in increasing entanglement.

Their applications diversify between automobiles, aircraft, space vehicles, and others because of their notable offer of mechanical properties, ease of fabrication, and super design flexibility. Moreover, fiber composites are distinguished due to their light weight, excellent fatigue strength, and good corrosion and impact resistance. The current paper investigates the mechanical behavior of a unidirectional fiber reinforced polymer composite lamina consisting of fibers embedded in epoxy resin as a matrix. Micromechanical analysis is done on a square-patterned unit cell of the above composite to predict the longitudinal modulus (E1), Transverse modulus (E2), In-plane shear modulus (G12) and Major Poisson’s ratio (Ѵ12). These engineering constant are evaluated to three types of fiber (E-Glass, R-Glass, and S-Glass) with various fiber volume fractions based on the theory of elasticity approach. Computer Aided Design Environment for Composites (CADEC) software is used to do the numerical analysis. This theoretical investigation helps to realize the bearing ability of unidirectional fiber reinforced composite subjected to longitudinal load by analyzing the engineering design constants. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Springer Science and Business Media Deutschland GmbH | 21954356 | |

Daily UVA exposures are weighted to the anatomical human cheek (anterior infra-orbital region) for teachers wearing and not wearing broad-brimmed hats. The method utilizes the OMI UVA irradiance data collected daily at high temporal resolution over 2005 to 2016 to derive the total daily UVA exposure to a horizontal plane. These horizontal plane exposures are scaled by factors to take into account the timing of outdoor activity. The relationship between exposures to a horizontal plane and those to a vertical plane and the protection provided by a broad-brimmed hat was assessed to evaluate the total daily UVA exposures to the cheek for classroom and physical education teaching staff expected to be outside at different periods of the day. The developed method enables the total daily UVA exposure to specific anatomical sites to be evaluated from the satellite solar noon irradiance at locations that do not have access to surface-based instrumentation capable of recording in the solar UVA waveband. © 2020 American Society for Photobiology | Blackwell Publishing Inc. | 318655 | |

The novelty of this model is that it is focused on providing specified numerical values of Quality of Service indicators such as flow rate and average packet delay. This was achieved by introducing into the multiflow routing model structure the corresponding Quality of Service conditions, which were formulated in an analytical form using the tensor research methodology. At the same time, the space metric was determined by both the service discipline of packets on the routers interfaces and the statistical model of the served flows. In addition, the conditions are formulated in such a way that for each flow transmitted in the network, the resulting average end-to-end packet delays along the set of calculated paths were the same and did not exceed the permissible values. The numerical example has demonstrated the adequacy of the proposed model in terms of the correctness of the obtained calculation results with regard to providing specified values of quality indicators that may differ for each of the packet flows transmitted in the network. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. | Springer | 21945357 | |

Wheat bran is the main by-product of wheat milling and contains >15% high-quality proteins. Extraction of wheat bran proteins (WBPC) and inclusion in spaghetti and bread formulations was studied to determine if the nutritional properties of these foods could be enhanced without deleterious effects on quality. Semolina was substituted with WBPC at 0, 1, 5, 10 and 20% (w/w) and made into spaghetti and a commercial bread flour was substituted with WBPC at 0, 1, 5 and 10% w/w and made into bread. Both spaghetti protein content (12.3 to 23.4%) and total essential amino acids (3.76 to 7.59%) increased with added WBPC. Overall spaghetti quality was acceptable up to 10%WBPC and superior to wholemeal, especially in appearance. However, the bread formulation used was very sensitive to WBPC especially above 1% addition. © 2020 Elsevier Ltd | Elsevier Ltd | 3088146 | |

During the past two decades, a sizable, but conflicting, body of literature has supported the use of roselle as a biological stain, and more specifically as a substitute for hematoxylin for staining nuclei selectively. We review the literature and suggest a rational explanation for divergent findings. When used without oxidation and mordanting, roselle is an indiscriminate oversight stain. With appropriate oxidation and mordanting, roselle can be an effective nuclear stain. We propose here use of a stain that is formulated rationally and followed by treatment in a differentiating solution that also acts as a counterstain. We also offer suggestions for improving roselle for the general scientific community. © 2020 The Biological Stain Commission. | Taylor and Francis Ltd. | 10520295 | |

With the help of Internet of Things, IoT industry, connected sensors have a considerable impact on data collection and remote engine monitoring. Mechanical engineers and professionals have difficulties determining when an engine is going to have a malfunction. So, engine maintenance requires an adequate strategy to predict the closest time in which an incident would likely to occur. This research investigates a perfect solution so that engineers will have an earlier alert about the potential incident which might exist. This study gives a visualized time left for how long an engine lifetime is present, accordingly, the system notifies the engineers of the best time to implement the maintenance. The methodology that we follow is setting up an appropriate mechanism by collecting data with IoT, and analyzing such data with classification algorithms. These algorithms categorize the status of an engine into particular conditions, so they indicate how far an engine going to work in an optimal state. Experiments have proved that K-Near Neighbor is the best algorithm for this kind of work in between others like; decision tree and linear discriminant with accuracy 82.9%, 51.0%, and 64.9% respectively. Consequently, classification techniques confidently distinguish the engine condition and warning for necessity of maintenance at the right time and right status. © 2020 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Two types of glass fiber reinforced polymer (bar, mat) were investigated for the strengthening materials. A simulated corrosion rate of 25% was considered in the study. The maximum recorded load of the strengthened beams with GFRP bars showed enhancement in the ultimate strength which reached 89% of the undamaged control beam strength. While using of GFRP mat for strengthening the corroded beams increased only the ductility but had negligible effect on the improvement of ultimate strength. The results indicated that using near surface mounted technique prevents the occurrence of de-bonding failure which results in an enhancement in the crack load and failure load of the tested beams. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

Traditional methods based on manual approaches applied in seizure detection in electroencephalograms (EEG) have drawbacks (e.g., time constraint, lack of effective feature identification relative to disease symptoms and susceptibility to human errors) that can lead to inadequate treatment options. Designing an automated expert system to detect epileptic seizures can proactively support a neurologist's effort to improve authenticity, speed and accuracy of detecting signs of a seizure. We propose a novel two-phase EEG classification technique to detect seizures from EEG by employing covariance matrix coupled with Adaptive Boosting Least Square-Support Vector Machine (i.e., AdaBoost LS-SVM) framework. In first phase, the covariance matrix is employed as a dimensionality reduction tool with feature extraction applied to analyse epileptic patients’ EEG records. Initially, each single EEG channel is partitioned into respective k segment with m clusters. Subsequently, covariance matrix is adopted with eigenvalues of each cluster extracted and tested through statistical metrics to identify the most representative, optimally classified features. In the second phase, a robust classifier (i.e., AB-LS-SVM) is proposed to resolve issues of unbalanced data, to detect epileptic events, yielding a high classification accuracy compared to its competing counterparts. The results demonstrates that AB-LS-SVM (optimised by a covariance matrix) is able to achieve satisfactory results (>99% accuracy) for eleven prominent features in EEG signals. The results are compared with state-of-art algorithms (i.e., k-means, SVM, k-nearest neighbour, Random Forest) on identical databases, demonstrating the capability of AB-LS-SVM method as a promising diagnostic tool and its practicality for implementation in seizure detection. The study avers that the proposed approach can aid clinicians in diagnosis or interventions to treat epileptic disease, including a potential use in expert systems where EEG needs to be classified through pattern recognition. © 2020 Elsevier Ltd | Elsevier Ltd | 9574174 | |

Semitransparent p-type semiconducting NiO x films were utilized as a hole-transport layer. Devices based on the ZnONd considerably outperform those employing ZnO thin films. The contact and electrical properties of NiO x can be carefully tuned through controlling the deposition parameters as well as surface treatments. Intimate contact between NiO x with PANI, created by in situ electrochemical polymerization, greatly improves the charge movement. Furthermore, an O2-plasma treatment of the NiO x film has a significant impact on the performance of polyaniline/ZnONd hybrid photovoltaic devices, reflected by the enhancement in the fill-factor and efficiency. The power conversion efficiency of the ZnONd/PANI/NiO x device under the optimized O2 plasma condition can reach up to 2.79% under AM1.5 illumination. © 2020 The Author(s).

We additionally examine the impact of hereditary and microbiological determinants on IL-10 articulation levels in periodontal injuries. Approach: 117 patients with incessant periodontitis and 58 controls were enrolled. At that point microbiological tests were gotten from the clinical assessment and the presence/bacterial heap of types of periodontopathogens was evaluated by RT-PCR. The genotype for IL-10-592C/A was dictated by limitation section length polymorphism. Results: The allelic dispersion of SNP rs1800872 in the explored populace agreed to the Tough Weinberg balance (p = 0.64). As has just been accounted for, polymorphic subjects indicated a lower articulation of IL- 10 and an expanded danger of experiencing interminable periodontitis. He IL-10-592C/A polymorphism demonstrated no relationship with the recognition or bacterial heap of any of the explored microscopic organisms, furthermore the IL-10 articulation levels were not impacted by the microbiological profile, yet were straightforwardly associated with the genotype for the IL- 10-592C/A polymorphism. © 2020 EManuscript Technologies.

Ten E.coli out of sixty uropathogen clinical strains were isolated from patients suffering from UTIs after culturing the urine samples onto Eosin Methylene Blue, blood agar, and MacConkey, plates agar based on the distinctive colonial morphology of E.coli. Results of API20E system did confirm the identity of the uropathogen ten clinical strains as E.coli. ERIC1b-PCR did show a high potential in discrimination of the ten clinical strains into three groups with respect to their DNA banding patterns. The frequency of occurrence of the three virulence genes stx, espB, and EAF among the ten E.coli clinical strains under study was 100%; inferred from the resulting banding profile of PCR partial amplification with 399, 518, and 633 bp. The present data would underpin the potential of ERIC1b-PCR for strict differentiation among the uropathogen E.coli clinical strains. © 2020, Advanced Scientific Research.

Its performance depends entirely on the value of time quantum. In this paper, an efficient ETRR scheme is proposed. This technique proposed the partitioning of the ready queue into three sub-queues: highest, medium, and lowest priority. It was found out that the assignment of the time quantum value (TQ) to one of those sub-queues is depending on a threshold value. Every sub-queue uses RR scheduling with separated dynamic time quantum TQi for i=1, 2, and 3. All processes in TQ1 must be executed first. Then are in TQ2 and TQ3, respectively. The experimental results show that the ETRR is outperforming other approaches such as SRBRR, ISRBRR, and MFQ. © School of Engineering, Taylor’s University | Taylor's University | 18234690 | |

The first part of the present study is devoted to review the construction process of chimneys, their shapes and dimensions, and properties of masonry units in which chimneys with heights 45, 50, 60, 70 and 80 m were studied. The second part focused on the wind loading analysis using CFD modelling and compared it with wind loads obtained by ASCE7-10, where three wind velocities were taken 30, 42, and 50 m/s. The third part related to 3D numerical model using finite elements method via ANSYS 2020R1 software to study the structural behavior of chimneys under gravity and wind loads in term of deflections and stresses. It is found that chimneys with slenderness ratio up to 11.6 (height = 60 m) re satisfied the design codes requirements for all wind velocities 30−50 m/s for permissible tensile stress, namely with a the factor safety greater than 2.The lateral deflection at the top of the chimney, of heights 45 m and 50 m, for all wind velocities is within permissible limit i.e. (H/650).Wind loadings estimated by CFD analysis is greater than that calculated by ASCE7−10 by about 37 %. © 2020 The Authors | Elsevier Ltd | 22145095 | |

These bacteria most often infect immunocompromised people, and treatment is often difficult and complicated for those infected due to multiple resistance. This review also demonstrated the benefit of using plant extracts and aromatic oils as alternatives to antibiotics as an inhibitor against P. aeruginosa. During previous studies, it was shown that most of the isolates were distributed among burn infections, wounds, urinary and respiratory tract infections, sputum, and blood poisoning. In addition, this review focused on virulence genes and their major role in bacterial resistance to antibiotics, as well as identifying the main P. aeruginosa genes to be used in the speed of diagnosis. Among the most important of these virulence factors is biofilm formation, β-lactamase production, Pyocyanins, and other enzymes. This review also identified the differences between clinical and environmental isolates and the extent of the effect of random use of antibiotics and the modifications that occurred to bacteria that made them resistant to these antibiotics. © 2020 EManuscript Technologies.

We used the DFT method, which implemented in the Quantum espresso package, to calculate various electronic properties computed. These impurities altered the behavior of the GNS from metal to semiconductor. Metal-doped GNS and anticancer drugs/pristine GNS became more stable and lower reactivity due to the total energy of these structures increased compared to the pristine GNS. The electronic band gap of the anticancer drugs/pristine GNS rehabilitated and opened. Furthermore, the metal-doped GNS as a carrier to the anticancer drugs was an exothermic process. Then, anticancer drugs/metal-doped GNS thermodynamically stable due to these structures have negative adsorption energies. Besides, we detected that these complex structures were required higher energy to donating/accepting and electron to become cation/anion due to these structures have a lower value of the electron affinity and higher value of the chemical hardness. Moreover, there was a great interaction between pristine GNS and metal impurities; also between metal-doped GNS and anticancer drugs. Then, GNS and metal-doped GNS have been used as drug delivery systems. © 2020 | Physical Society of the Republic of China | 5779073 | |

The two-step technique is used to prepare ionanofluid (INF) by dispersing multi-walled carbon nanotubes (MWCNTs) in two concentrations 0.5 and 1 wt% in ionic liquid (IL). Two types of ionic liquids (ILs) were used: hydrophilic represented by 1-ethyl-3-methylimidazolium tetrafluoroborate [EMIM][BF4] and hydrophobic represented by 1-hexyl-3-methylimidazolium hexafluorophosphate [HMIM][PF6]. The thermophysical properties of the prepared INFs including thermal conductivity (TC), density and viscosity were measured experimentally. The TC measurement showed an enhancement of about 3% for INF and of 1% MWCNT in [EMIM][BF4] at a temperature of 298.15 K: the TC was 0.186 W/m.K, the kinematic viscosity was 100 centistokes (cSt), and the density was 1.283 g.cm-3. On the other hand, the TC of 1% MWCNT in [HMIM][PF6] INF enhanced by 5%. In this case, at a temperature of 298.15 K, the TC was 0.158 W/m, the kinematic viscosity was 1200 cSt, and the density was 1.294 g.cm-3. Furthermore, the stability of the prepared INFs was measured using the zeta potential method after 28 days of preparation. The results show very good dispersion of the nanoparticles in the ILs for all the prepared INFs. The zeta potential was -69.30 mV and - 45.34 mV for 0.5% and 1% MWCNT in [EMIM][BF4], respectively. On the other hand, zeta potential was -51.78 and -46.67 mV for 0.5% and 1% MWCNT in [HMIM][PF6], respectively. According to the obtained results, the preferable INFs to use as a cooling medium at 25 °C was the INF of 1 wt% MWCNT in [EMIM][BF4], since it provides better thermophysical properties than the other prepared INFs. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

This study utilised a natural adsorbent, kaolin clay to remove pollutants' dye (Methylene Blue) from aqueous solutions. Batch studies were conducted to evaluate the adsorption efficiency for dye removal from aqueous solution under varying conditions such as initial pH (pH), contact time, initial dye concentration on adsorption of dye. The optimum pH was found to be 6. The investigations in this study showed that 83% of dye removal can be achieved at the first 50th min. Meanwhile, 60 min was enough to reach the equilibrium state. Additionally, the results revealed that 100 mg/l of kaolin can lead to increase the 83 mg/g of adsorbed dye amount. The maximum removal was 89 % when the quantity of kaolin dosage increased to be 1.5 g. To sum up it, using kaolin as adsorbent material showed high efficiency to remove the dye which can be another addition for serious water pollution treatment efforts. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

The results show that all modes except TE 1 achieved forward propagation and then turned backwards. The effective refractive index value at which the propagation type is reversed increases with the mode order and the thickness of the middle layer. In addition, an anisotropic property in the metamaterial layer shift the modes curves (exept TE 1) to left or right with respect to the isotropic case. Furthermore, the mode TE 1 is abnormal and inconsistent with the behavior of other modes. Except TE 1 mode, the confinement factor is small in the forward propagation region and reaches large values in the backward propagation region. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

Graph theoretical systems have many good features among different segmentation schemes. It organizes the image elements into mathematically and structural form, and makes the problem formulation more flexible, and the computation more efficient. In this paper, the work, consists of two stages, in the first stage we apply the pixel-based labeling algorithm to the binary image, the algorithm works similarly to the eight connectivity labeling, but it is broader than it in terms of the search area, where two (horizontal and vertical) thresholds are first defined so that the search is in a block whose height is the vertical threshold and its width (2 ∗ horizontal threshold), in the second stage the output of the first stage is mapping into an undirected weighted graph, in which each vertex represent region rather than pixel. We evaluate the results by comparing it with other method using (RI) parameter.

There have been several routing algorithms commonly set up WSN. In the sensor network, a large number of inexpensive sensors with small batteries are deployed in the area to be monitored, which has to survive for a long time, where it is difficult or even impossible to implement the sensor battery replacement. Consequently, power consumption is an important factor to consider when designing WSN. We proposed a new scheme to investigate the cluster in heterogeneous WSN, the clustering by using Fuzzy-Logic Stable Election Protocol (SEP-FUZZY), since the Fuzzy Logic Inference System (FIS)is used in the clustering process. FIS work with two input (nodes' remaining-energy(R-energy), and its distance from the base station(D2BS)). Results from the simulation indicate that the lifespan of the network reached by the suggested approach will be improved by almost (47 %, 35.7 %, and 23.8 %) more than that gained by the protocols "(LEACH, PEGASIS, and SEP)". © 2020 Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

To help accelerate these efforts, we have performed a research for tautomers formations of favipiravir as possible RNA polymerase enzyme inhibitors and mitigating the virus ability. This study provides important electronic and optical properties of tautomers determined by density functional theory (DFT) and time-dependent density function theory (TD-DFT) calculations in gas phase and in water. A series of favipiravir derivatives was designed, and study the effect of the HOMO-LUMO energy gap on the efficacy of inhibitors. It has been determined that H-atom positions change and substituting fluorine (F) by hydroxyl (OH) group of tautomers affects the energy gap and dipole moment values. Among all compounds, the results have shown that Fb4 form with OH is most potent inhibitory activity in both gas phase and water. These investigations indicated that these tautomers could be potentially developed into drugs, but further investigations are still required to examine the cytotoxicity and consequent side reactions. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

The modes and the effective refractive index associated with each wavelength were derived using the COMSOL MULTIPHYSICS based on the Finite Element Method. The electrical permetivity was studied using the relationship Lorentz derode to determine the real part for the refractive index and the imaginary part responsible for the attenuation coefficient. Where a frequency range was chosen to hold negative values for the real part. The results show that when drawing the relationship between (ϵr ) or (ϵi ) a function of the wavelength that gold has the highest value and then silver, copper and then aluminum, but in the case of (nr ) or (ni ) we notice that aluminum has the highest elements. (neff ) has also drawn as a function of the wavelength, the four metals, and different of the core radius (a=100, 200, 300, 400, 500) for the three modes (LP 01,LP 11,LP 21) and the metal used. It is observed that increasing the mode index increases the lobes where the mode (LP 01) is one spot and the mode (LP11) is two spot and the mode (LP 21) is four spot, where the power index increase is the increase in red and yellow color, and this applies to all modes. In other words, by controlling the radius of the core and wavelength, we can balance the ratio of power that propagation forward and backward. The refractive index (neff) has the highest value at small wavelengths and then begins to decrease with increasing wavelength, and has the highest value in the case of gold, then silver, then copper. Then aluminum, which is less than the rest of the elements. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

It provides services on-demand based on pay-as-you-go basis. Task scheduling and load balancing are important research issues in cloud computing. Task scheduling means distributing tasks to resources (Virtual Machines) while load balancing refers to distribution tasks among resources to even workload. In this paper, we propose an Effective Load Balancing Algorithm with Deadline constraint (ELBAD). The ELBAD allocates nearest deadline tasks each time to the highest speed Virtual Machines (VMs) then it balances workload among VMs. The proposed algorithm is compared with other existing algorithms such as FCFS, SJF, Min-Min and EDF and experimental results show superiority of ELBAD over others with respect to minimizing makespan and maximizing resource utilization. © 2020 Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

The mechanism of this study is utilized the Bilayer (BL) MSe2 and MS2 to delivery β-lapachone (β-lap) anticancer drug by putting this molecule up on the slabs. Density Functional Theory (DFT) method is applied in the Quantum espresso package to compute various electronic properties. Results demonstrated that the pristine BL MSe2 and MS2 have a semiconductor behavior with indirect electronic band gaps. The complex structures (MSe2/β-lap and MS2/β-lap) have different electronic properties. So, there is a very small electronic band gap with direct transition at the K point for MSe2/ β-lap structure and at K-Γ region for WSe2/β-lap structure. For MoS2/β-lap and WS2/β-lap structures, the electronic band gap also reduced with indirect transition. For the stability of the complex structures, our finding revealed that all these structures became more stable and lower reactive with this anticancer drug due to the total energy is increased compared to the pristine cases. The chemical hardness of the complex structures is a small, which led to the smaller excitation energy required to transfer electrons. Moreover, they have higher ability to transfer electrons. There are smaller separation distance between the valence and conduction bands due to these complex structures have smaller value of the chemical softness.

Based on this factor, this paper reports the surface morphology, structure and corrosion resistive traits of some multi-walled carbon nanotubes (MWCNTs) coated porous Ti-30 at.%-Ta shape memory alloys (hereafter coded as MWCNT-TTSMAs). The electrophoretic deposition (EPD) technique at various applied voltages was used to coat these alloys with MWCNTs. The structures and morphologies of the prepared samples were characterized at room temperature using the X-ray Diffraction (XRD), energy dispersive spectroscopy (EDS), Raman spectroscopy, Scanning Electron Microscope (SEM), Atomic Force Microscopy (AFM) and Transmission Electron Microscope (TEM) measurements. In addition, the corrosion resistance of the coated alloys was assessed via electrochemical impedance spectroscopy (EIS) in the simulated body fluid (SBF) solution. The thickness (increased from 10.05 to 25.93 μm), surface roughness (increased from 1.38 to 1.95 μm) and homogeneity of the coating was significantly affected by the increase in the applied voltages (0 to 50 V). The corrosion rate of the optimum coated specimens was 10 fold lower (0.0966 mm/year) compared to the uncoated one (0.9403 mm/year). The hydrophilic nature of the proposed MWCNT-TTSMAs affirmed their osseointegration potential to support the cell attachments. The mean water contact angle (WCA) of the coated samples indicated a hydrophilic surface with a value of 22° ± 6 compared to the uncoated sample that exhibited a hydrophobic surface with the WCA value of 96°. Thus, the surface of the MWCNTs tends to be hydrophilic, resulting in an improved surface wettability. Antibacterial activity test exhibited that TTSMAs presented minimal inhibition area toward Escherichia coli (E. coli), in contrast, using the MWCNT has shown an improvement in antibacterial performance. © 2020 Elsevier B.V. | Elsevier B.V. | 2578972 | |

However, the complex matrix structure of lignocellulosic materials complicates conversion processes, such as enzymatic hydrolysis. Therefore, an efficient pretreatment process is required to disrupt the plant cell wall structure and maximize the recovery of valuable soluble components from lignocellulosic biomass during hydrolysis. In addition, an effective pretreatment method should use the minimum necessary amounts of energy and chemicals to minimize the cost of the end product. Further, it should reduce the formation of inhibitory compounds that affect enzymes and microorganisms during hydrolysis and fermentation, and it should be applicable to a wide variety of feedstocks. The research presented in this review has highlighted the pros and cons of the current technologies employed in pretreatment processes. Further study should be done to optimize and improve these technologies to enhance the efficiency of the production of biofuels and other valuable components. © **.

However, under circumstances of leaking hydrocarbon products into expansive grounds, the perspective of using such technique in identifying the degree of contamination is still obscure and needs more investigation. In this research, six identical resistivity boxes are self-instrumented in the laboratory to test samples of different clay-bentonite mixtures upon oil contamination. The samples are tested under various control conditions of densification and water content. Each soil mixture is artificially contaminated with crude oil at a certain percentage ranging from 0% to 25% of its dry mass. The outcomes show that electrical resistivity increases with the addition of oil, and that is highly noticed for the samples characterized by high swelling potential. Also, increasing the dry unit weight of expansive polluted samples contributes to raising the resistivity measurements. However, adding more water to the contaminated samples causes a noticeable reduction of the resistivity measurements. The obtained results could be used as a guide for use in soil remediation concerning polluted ground. Thus, the study contributes to producing a reliable alternative to using costly, time and effort consuming conventional tests. © Alpha Publishers.

The density matrix theory is used to write the equation of motion and an orthogonalized plane wave is used between WL-QD states. The results show that the DQD system exhibit NRI ordinarily until with pump and probe signals, only, due to the manipulation between states. A high NRI corresponding to neglected absorption is obtained under applied electric fields between QD-QD, the conduction (CB) and valence bands (VB) WL-QD fields. It is shown that the main requirement in increasing NRI is the high electric gain connected with a low magnetic one. This can be obtained under five applied electric fields in addition to a high VB WL-QD electric field. Neglecting WL reduces NRI by ~ 16 times. In single QD, the NRI is very small compared with DQD. © 2020, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

These properties depend critically on a number and type of impurity are founded in the ribbon (the width and the nature of the ribbon edge are constants). Finally, the calculation has involved optical properties of all paradigms such as geometrical structure, HOMO, LUMO, total energy, Fermi level energy, binding energy, work function, polarizability and hyperpolarizability respectively of each the structures studied. Herein, the both 8Al-GNR and 8P-GNR are the highest reactivity structures among all specimens (viz 1046.008 and 1035.1623 a.u) respectively. The results elucidate that the first hyperpolarizabilities of GNRs paradigms before and after doped were 0.0354 esu and 2855.87 esu, respectively. The results bring to light that the effect of contaminations is to greatly increase the hyperpolarizability value. The high values of polarizability and hyperpolarizability exhibit that the paradigms have very useful linear and nonlinear optical implementation as well as, the computation has included of the values of wavelength of maximum emission, vertical excited of energy, oscillator strength, optical energy gap, and cases of major electronic transition, where each studied paradigms were simulated using TD-DFT with B3LYP/6-31G (d, p). Interestingly, the optical band gap was evaluated of pristine GNRs and found equal to 0.6256 eV. Whereas, the value of doping in GNR can be noted that the band gaps are sometimes shrinks and other times expands. These values are determined between (0.1018 eV to 1.276 eV) for paradigms 2Al-GNR and 4P-GNR respectively.

Maintenance works should be conducted periodically and without delays; otherwise, the needed fund may be increased swiftly. The essential need for reviewing, assessing and maintaining roads requires continuous provision of fund. As a result, applying new alternative management system that ensure non-stopping fund is a necessity. The private sector can effectively involve in financing roads projects in direct investment or in partnership with the public sector. In this research, the Basra-Nasiriya expressway highway was evaluated to assess its current status in terms of road condition, signs, furnishing, existing services and maintenance procedures. The data included in this study was obtained from two resources; the first is primary from conducting two questionnaire-based surveys to collect opinions and knowledge from road users and experts. Field inspection survey was also performed.The experts indicated that the lowest acceptable level is 3.5, thus the road is close to reaching a level that beyond it a maintenance should be performed. Since the main problem is to find an effective management system that allows the provision of the necessary funds and hence ensure continuous maintenance, a toll road system has been proposed to collect fees from road users. Finally, this system was found to be acceptable at 87% of the surveyed sample. It was also confirmed that the legal basis for applying this system is available in Iraqi law and its prevailing legislations. © 2020 Author(s). | American Institute of Physics Inc. | 0094243X | |

They contemplate two nodes at the same level strategically optimising their decisions over a finite set of strategies. Specifically, they consider two strategies are available to each node. Nodes can choose to transmit to keep the network updated, but at the risk of not sensing during the transmission time and the potential of sending repeated information if other nodes have already transmitted that information. Nodes can choose to sense the environment to detect new events, but this strategy leaves the network with outdated information if all nodes adopt it. As a result, nodes have to strategically make their decisions depending on the nodes' parameters, the importance of information, and the locations of the head nodes. They tackle this decision-making problem using two game theoretic models: A non-cooperative two-player game model and a potential game model. They derive the Nash equilibria (NE) and highlight their existence conditions. Finally, they use learning algorithms that use local information at each node to reach the NE. These algorithms are the fictitious play (FP) algorithm and a modified FP that is inspired by the cumulative proportional reinforcement algorithm. © 2020 The Institution of Engineering and Technology. | Institution of Engineering and Technology | 17518628 | |

Methods: twenty-four of female rats (Rattus norvegicus) were utilized for this purpose. Animals were further distributed in four groups having six rats in each group. Diabetes was induced by injected intraperitoneally with alloxan at single dose 125mg/kg body weight, group (1) (control group): animals of this group were treated only with distill water for 15 days, group (2) (diabetic group): animals of this group were injected intraperitoneally with alloxan at single dose 125mg/kg body weight, group (3) (taurine group): a 100 mg/kg body weight dose of taurine was intraperitoneally introduced for fifteen days, the group (4) (DM+taurine group): animals of this group intraperitoneally injected a single dose of (125mg/kg body weight) alloxan and after 7 days they were injected with taurine at a dose (100mg/kg body weight) for 15 days. Results: a significant upsurge (P≤0.05) was indicated in diabetic rats in the AST, ALT urea and creatinine’s levels. In addition, taurine supplementation caused a significant decrease in the levels of ALT, AST, urea and creatinine. Conclusions: taurine could have potential as a pharmaceutical drug for diabetes mellitus (DM). © RJPT All right reserved. | Research Journal of Pharmacy and Technology | 9743618 | |

Our investigation also revealed that studies scrutinizing iron deficiency anemia (IDA) are also rare all around the world. The aim of this research was to determine metal concentrations and physiological parameters in SCA patients and compare them with IDA patients. In this study, 31 SCA patients, 30 IDA patients, and 28 healthy people (male and female) were recruited from the Center of Genetic Diseases, Thi-Qar, Iraq (age range: 2-45 years). The blood types of all participants were recorded from their profiles. 5ml blood was collected from both patient and healthy groups to determine reticulum cells by slide method; other hematology tests were performed by hematology analyzer. The rest was centrifuged to obtain the serum used to determine ferritin level by minividas, vitamin D by cobas, and metals including copper, zinc, magnesium, and selenium by flame atomic absorption spectrophotometer. The age of IDA group was significantly higher than that of SCA group, while no significant difference was found in the gender of the two groups. In both groups, the highest frequency was found in the O blood type and the lowest in the B blood type. The results of estimated parameters showed that both anemia patients have significantly lower RBC count, Hb level, vitamin D level, and PCV% than those in control. However, ferritin level, reticular cells %, and WBC count were significantly higher in the SCA, and significantly lower in IDA, compared to the control. Copper and selenium levels were significantly higher, while zinc and magnesium levels were significantly lower in both patient groups compared to control. Accordingly, regular laboratory examination of these elements is inevitable. © RJPT All right reserved. | Research Journal of Pharmacy and Technology | 9743618 | |

The objective of this study was to examine the preventive effect of different concentrations of Propylparaben (PP) for control of fungal populations and aflatoxin b1 (AFB1) contamination of stored chilli powder in both artificially and naturally contaminations. These treatments were examined at two different water activity (aw) levels (0.90 and 0.95 aw) in stored chilli powder at 30oC for 20 days. The total populations of A. flavus isolated from both artificially and naturally contamination of stored chilli powder at 30oC were significantly reduced by using PP treatments espe-cially, with 2000 ppm. In additions, the AFB1 production was reduced when increased PP concentration compared to the untreated control. In conclusion, the economic and health impacts related to Aspergillus and AFB1 contamination could be minimised by adding PP as a food-grade preservative to stored chilli powder, Results show From a human health perspective, the use of PP is allowed as a food preservative by the (IARC) and (WHO). It must use according to legislation doses (0.1%) introduced by the law of (GRAS) regulations. © 2020 International Journal of Research in Pharmaceutical Sciences. All rights reserved. | J. K.

Such thing lead to slight or serious injuries to these employees. In addition, it may cause physical injury and disability, low performance at job, and finally an uncomfortable working setting for the staff. Materials and methods: A descriptive study was applied to assess the prevalence of WPV and related factors. This study was conducted at the EDs of four teaching hospitals in Al-Nasiriyah city. Study sample was drawn from emergency physicians, nurses, pharmacists, and laboratory technicians. Both genders staffs were included. Results: The results involved answers from 426 employee in the emergency department. The most reported form of violence in the staff in the past year in this research was emotional violence, which is reported by 78.5% of the sample, then physical abuse (14.3%) and sexual abuse at last (5.2%). Conclusion: This study exhibited many findings on a group of WPV cases, in addition to the features and issues related to exposure to violence. The findings undoubtedly prove the priority of considering this issue in Iraqi hospitals and the importance to develop urgent and appropriate interventions. © 2020, Institute of Medico-Legal Publications.

Researchers have investigated the proliferation activity of the adrenal cortex especially in the capsule and sub-capsular areas. To date, no evidence has been found associating TMEM121 protein with the proliferation activity of the adrenal cortex. Our previous study suggested the expression of TMEM121 in the adrenal sub-capsular was high and co-localized with the proliferation marker (Ki67). These findings suggest investigating the role of TMEM121 in the propagating cells. The full-length coding sequence of the TMEM121 was amplified using RT-PCR and cloned into pIRES2-EGFP vector. Human cancer cell line MDA was prepared and genetically modified by transfection with Tmem121 and sustained as stable cell lines expressing Tmem121 for a fortnight to investigate its effect on the proliferation activity of these cancer cells. The expression of TMEM121 was successfully forced into these cells and its expression was maintained. However, the expression of Tmem121 has no significant effect on the proliferation activity of these cancer cells. The proliferation pathways of MDA cancer cells showed an independent behavior regardless of the dramatic increase of Tmem121 after transfection. © 2020.

Objectives: To assess knowledge and attitude about sexual transmitted disease among women in reproductive age in Al-Nasiriyah governorate-Iraq. Methods: Cross sectional study design based on community was conducted in in Al-Nasiriyah governorate in Iraq on women at reproductive age. Data collected by predesigned and pretested instrument through face to face interview. Results: In general literates women were more aware about STDs compared to illiterates. A total of 180 women at reproductive age were recorded, of which 325(64%) regard blood transfusion as major method of STD transmission and 206(40%) Through the open wound of the genitals. 384 (68.3%) women told that vaginal discharge is common symptom, followed by Genital and mouth ulcers 194(34.5%). 310(61%) women regard diagnosis of STD done by blood test.396(78%) opined abortion common complication followed by 287(55%) infertility. 404(71%) opined that STDs can be prevented by abstinence from sex and 343(61%) it cannot be prevented. Conclusions: Based on the results of the study, women’s knowledge about sexual transmitted diseases that transmitted during sex is very low, so special programs must be provided for women that can increase knowledge of women and awareness of sexually transmitted diseases in Iraq and published on television and radio. As knowledge and awareness of diseases promote with education, special educational programs are also effective for education of women in Iraq about STD. © 2020, Institute of Medico-Legal Publications.

There are many types of contraceptives, some contain estrogen and the other contain progesterone, or combination of them in the same drug. This work was performed in a population of adult females to study the relationship between the chronic use of OCs with dyslipidemia and the threat of cardiac diseases. A total 163 volunteers were participated in this study, and, their aged between 21-42 years old. In addition, all women were free of heart disease, dyslipidemia and any hormonal disturbance according to their health records. They were categorized into three differnt groups, the control group included 52 unmarried women and does not use any OCs, group A: included 57 women took OCs (combination pill estrogen and progestin) for less than 6 months, and group B contained 54 women used OCs for more than one year. We meassued lipid profile, and blood indices of cardiovascular disease, like Creatine Kinase-MB (CK-MB), insulin, Lactate Dehydrogenase (LDH) albumin, leptin and HbA1c test. In addition, we determined the coronary risk index, atherogenic Coefficient, and an atherogenic index. Our results recorded a significant increase in total cholesterol, LDL, coronary risk index (TC/HDL), LDH and HbA1c in group2 compared to compared to control group. Furthermore, our data demonstrated no clear differences in Triglyceride, leptin hormone, TG, HDL, insulin, albumin and CK-MB in group2 compared to control. Moreover, the data indicated a significant elevation in the concentration of leptin hormone, LDH, HbA1c, TC, TG, LDL, coronary risk index, atherogenic Coefficient and Atherogenic index, and significant decline in HDL and albumin in group B compared with control group. Therefore, we concluded that oral contraceptive could deter the lipid profile status and some enzyme related to the cardiovascular system. These alterations convey a possible risk for the development of cardiac diseases. Routine screeing of lipid tests would be measured in women used OCs for long periods to avoid any potential risk of cardiac diseases. © 2020, Institute of Medico-Legal Publications.

Samples were collected for 12 months from 577 women with thyroid disorders (407 had hypothyroidism and 170 were suffering from hyperthyroidism). There were 192 women that were considered as a control group who were healthy and did not complain of any diseases. Some data, such as age, marital status and causes of infection for patients with thyroid disorder, were confirmed. TSH, T4, T3, total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were measured for all subjects. The study found that women whose ages are between 25–35 years and married women are more likely to have thyroid disorders than the total of the sample. It has been observed that the level of TSH and TG increase in women who suffer from hypothyroidism, but there is no difference in their level for women who suffer from hyperthyroidism in comparing with the control group. As for the hormone T4,T3 and fT4, their levels were high for hyperthyroidism group, but their level was lower in women with hypothyroidism. TC and LDL were more elevated in hypothyroidism and also high in hyperthyroidism group. While HDL level was more low in hypothyroidism, and it was also low in hyperthyroidism women when comparing its level with the control group. It was clear from the study that women between the ages of 25–35 years are more infected for non-hereditary reasons but rather disorders in their female hormones that negatively affect thyroid hormones. Imbalance of the lipid profile (Dyslipidemia) was also observed in patients with thyroid disorder, which could be one of the causes of atherosclerosis and coronary diseases. © 2020.

According to their SCCmec types and associated epidemiological and virulence factors, they can be classified into hospital-acquired MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA). Purpose: The objectives of the present was to study the diversity and distribution of SCCmec elements among MRSA isolates from outpatients and patients on admission into hospitals in at time of admission into hospitals. Methodology: The S. aureus clinical isolates were initially identified phenotypically using various biochemical tests and then this identification was confirmed by PCR using species-specific 16S rRNA primer pairs. Methicillin Resistant was determined using the disk diffusion method. All the identified isolates were subjected to mecA detection. Simplex PCR was optimized for all the major SCCmec types (I to V) and PCR products were sequenced to confirm our results. Results: Out of the 349 isolates, 75 (21.48%) were S. aureus. The antibiogram analysis of the isolated S. aureus strains indicated that these strains showed high resistance to oxacillin (93.33%), methicillin (90.66%) and 54 (72%) isolates possessed the mecA gene. The results showed that the predominate SCCmec type was type 1V 45% (34/75) followed by type I 6.6% (5/75) and 48% (36/75) carried multiple SCCmec types (type I and type IV). Types II, III and V were not detected. Conclusion: The existence of multiple SCCmec types in individual MRSA isolates rose difficulties in using SCCmec typing criterion. © 2020 Wolters Kluwer Medknow Publications.

Methods : 34of APL cases with multiple clinical and biological characteristics (age, sex, Presentation, APL type, Hb conc., WBC count, platelets count, % DIC presence, and promyelocytic percent) were studied, with adequate flow cytometry(FC) data, SSC, CD34, CD117, CD13, CD33, cMPO, HLADR, CD11b, CD64, CD2, CD56, CD35, CD36, CD58, C118, CD4, CD19, CD45, CD38, CD15, CD16 and CD79a of bone marrow aspirates, were analyzed for immunophenotypic pattern. Result: The patients were between 15 to 60 years old (the mean of age was 32 ±13.9). The male: female ratio was 14m: 20f (1:1.4) Immunophenotypic analysis revealed the majority (21 cases 61.76%) of cases represented classical (hyper granular) and the remaining were M3V pattern of APL. The clinical features ranged from, pallor and pallor/bleeding manifestations in (18%), till spleen and liver enlargement in 6% of cases. The hemoglobin levels ranged from 4 to 11.1 g/dl with a mean of 8.29 g/dl. The WBC count ranged from 0.5 to 56 x 109/l with a mean of 10.15 x 109/l. Platelet counts ranged from 1.9-87 x 109/l with a mean of 36.5 x 109/l. promyelocytic cell percentage ranged from 13 to 96% with mean of 71%. Disseminated intravascular coagulation (DIC) was found in about 56% of cases ranged as 48% and 69% in classical and M3V disease pattern respectively. APL cells typically highly expressed hallmarks of APL: CD33 (~88%), CD13 (~85%), CD64 (~77%),CD 117(~76%) and dimly expressed associated AML markers such as HLA-DR, CD4, and CD19(~3%). In addition to all cases were negative for CD15, CD16, CD38, CD76a, and cTdT.

In addition to overt infection, occult Hepatitis B infection exists in which a patient who is diagnosed seronegative for Hepatitis B surface antigen (HBsAg) shows positive HBV-DNA on using more accurate molecular methods. This study aims to determine the prevalence of overt and occult HBV infection among the HD patients who had attended Al-Nasiriyah dialysis centre during a two-month period. Materials and Methods: Serological qualitative detection of HBsAg by rapid test (strips), enzyme immunoassay (EIA, HBsAg) and molecular (real-time polymerase chain reaction (real-time PCR)) was conducted for quantitative detection of HBV in HD patients’ serum. Results: The prevalence of overt HBV infection among HD patients was 3.7%. The viral load of HBV positive patients was ranging from 5.85 × 101 to 2.16 × 106 copies/ml of serum with median (7.4 × 105 copies/ml). Occult Hepatitis B was not detected in any of the seronegative HD patients (0%). Overt infection was found more in males (80%) than females (20%) (P<0.05). Similarly, infection was found to be higher among patients who had blood transfusions (80%) than those who had not (20%) with statistical significant p<0.05. Although not statistically significant, the mean duration of HD was higher among HBV positive HD patients (17.6) than HBV negative HD patients (14.3). A dual infection of HBV and HCV was not detected in this study. Conclusion: Nosocomial transmissions at HD centres and blood transfusion are important risk factors. Besides serological screening, real-time PCR offers a safeguard against the spread of overt and occult HBV infection and determines the viral load of the positive patients. © 2020, Tehran University of Medical Sciences.

Two forms of sewage sludge were used, sun dried sewage sludge (DSS) and sewage sludge ash (SSA). SAA was produced by incineration of the DSS at 600°C for two hours. DSS and SAA were separately used as a partial replacement of cement in concrete mixes. The produced concrete mixes were experimentally tested via various mechanical and physical concrete testes such as compressive strength, workability, and water absorption. DSS and SSA were chemically characterized. Then, they were manually ground, sieved through sieve size of 150 μm, and added to the concrete mixes as a proportion of cement content using 5, 10, and 15% as cement replacement of cement content. 1% of a super plasticizer was added to the concrete mixes that prepared using two contents of cement 450 kg/m3and 550 kg/m3. The results showed that DSS chemically included 21.973% of SiO2 while SSA contained of 38.71% SiO2. The concrete mixes containing 5 and 10% of cement replacement by DSS showed slight increments in compressive strength compared to the concrete control at the final age of 28 days. The increments were 0.25, 1.58 % and 0.36, 2.02% for mixes of 450 kg/m3, and 550 kg/m3 of cement content, respectively. Meanwhile, the employment 10% of SSA appears higher increasing in compressive strength at the age of 28 days, by 8.05% and 8.90% for cement content of 450, and 550 kg/m3, respectively. Water absorption of DSS or SSA concrete samples also showed a decrease in water absorption percentage compared to control concrete samples. Therefore, recycling DSS and SSA could provide another route for cheap cement materials, and a potential alternative to landfill process. © School of Engineering, Taylor's University | Taylor's University | 18234690 | |

To get the random lasing, the samples were exposed to Picosecond laser. Our results show a gradual increase in the random lasing emission by increase in the concentrations and thus scattering mean free path until the threshold amount. The emission intensity was enhanced by enhancing the laser power due to an increase in scattering, which cannot make a close loop path in the gain medium to reach the coherence random lasing. Our results showed efficient emission intensity due to the absorption of Rhodamine B with Ag NPs in the pumping wavelength where it has been observed that the lasing threshold is reduced from 0.628 A (without scatterer) to 0.62 A at 9.2∗1017cm-3 Likewise, the lowest FWHM (full width at half maximum) for this concentration was 34 nm, while without concentration it was 37 nm, but the clear and important difference is that the first occurred at 72 A, while the second state at 80 A. © 2020, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

To realize suitable and optimized adsorption of the four anticancer drug molecules (6-MP, GB, 5-FU and CP) on the ZnONS surface, we substituted various concentrations of Zn atoms with Ga impurities on the ZnONS surface. Then, we studied different electronic properties of the nGa-doped ZnONS and numerous drug molecules adsorbed with nGa-doped ZnONS in the vertical and horizontal directions via a DFT calculation. There are exacted interesting results. The behavior of ZnONS is converted from semiconducting to semimetal. That means the huge quantity of charges are carried in the system. Besides, n Ga-doped ZnONS become more stable and lower reactive due to the total energy is increased. The exchange-correlation and electrostatic energies are improved, excepted kinetic energy has opposite behavior. Due to we observed the structure becomes more stable with different concentrations of Ga impurities; we studied the above electronic properties of the drug molecules adsorbed with n Ga-doped ZnONS in the vertical and horizontal directions. We found out the electronic properties is not only depended on the type of the drug molecules, but also depended on the direction of the drug molecule. So, the electronic properties are very sensitive to the drug molecules in the horizontal more than in the vertical direction due to the shape of the electronic band structure is exchanged and the overlapping of the conduction and valence bands are more increased in the horizontal than in the vertical directions. Then, we can employ n Ga-doped ZnONS as a carrier of drug molecules. © 2020 | Elsevier B.V. | 13869477 | |

In order to ensure best funding allocations and most effective maintenance and repair activities, the reliability of NDE technologies for a particular application needs to be carefully assessed to determine the margin of error (MOE) of NDE data. This research aims to investigate the utilization of “Wilcoxon-Mann-Whitney (WMW) Statistics” for the reliability assessment of NDE technologies. The reliability of three of the most widely used NDE technologies for the detection of subsurface cracking in concrete was assessed using WMW analysis. The NDE technologies assessed were: Impact Echo (IE), Infrared Thermography (IRT), and Ground Penetrating Radar (GPR). Two in-service bridge decks and two full-scale fabricated deck slabs were nondestructively tested to provide suitable data for analysis. The in-service bridge decks contained areas of mild and severe subsurface cracking as determined from previous testing performed by the Missouri Department of Transportation (MoDOT). The fabricated decks, on the other hand, contained areas of synthetic cracking of different sizes and depths. The reliability indices determined from WMW analysis for the three NDE technologies discussed in this manuscript are exactly equivalent to the indices determined previously by the same authors using Receiver Operating Characteristics (ROC) analysis. Results of WMW analysis, by the way, indicated that IE and IRT technologies were more reliable than GPR for the detection of concrete subsurface cracking. The final WMW indices of IE and IRT data were much higher than the corresponding indices of GPR data for both the in-service bridge decks and the fabricated slabs. The interesting equivalence between WMW and ROC analyses may encourage other researchers to utilize the former method in order to investigate the reliability of other NDE technologies in other applications. The findings of this research may also assist decision-makers considering the use of these NDE technologies in order to form decisions regarding maintenance and repair needs for bridges. © 2020 Institution of Structural Engineers | Elsevier Ltd | 23520124 | |

Compression index (Cc) is used to predict the compressibility of soil and estimate how much settlement which is occurred due to loads of different engineering structures. In this study, soil investigations reports were used for the city of Al-Nasiriya which were carried out by the national construction laboratories. Physical properties results showed that Al-Nasiriya city soil has a low to high compressibility and it is classified as inorganic clays of medium to high plasticity. The simple linear regression analysis was applied for estimating compression index indirectly through using some properties of soil indices such as atterberg limits. The correlation coefficient of the linear regression model indicated the presence of reasonable relationships between the compression index and the parameters proposed in this paper. The obtained results showed that the best model is capable of predicting the amount of compression index and with higher accuracy is based on liquidity limits in regression analyses. There is also a reasonable agreement between measured and predicted compression index values in addition to presence a small difference between calculated values using statistical properties for atterberg limits. The empirical equations obtained from simple linear regression model can be reliably used in engineering designs for study area with high confidence. © 2020, Springer Nature Switzerland AG. | Springer | 9603182 | |

Most studies focus on gathering insight on risk factors from researchers or management-related employees using a cross-sectional survey. This study aimed to investigate and rate key factors contributing to worker safety—namely site conditions, as well as human, environmental, social, economic, organizational, regulatory, psychological, and ergonomic factors—from a worker perspective. The impact of these factors was determined in terms of the amount of risk added to the risks resulting from the degrees of connectivity (DoC) model scenarios—a novel accident causation model. The study also aimed to determine whether particular trades are associated with differing risk levels related to these factors. Responses from a sample of highly experienced construction workers from the northwestern region of the United States were collected, refined, and analyzed after several rounds of surveys using the Delphi method. The research results show that organizational factors are perceived to have the greatest impact on construction worker safety, while human factors have the least impact. The results also reveal no association between the trades and the risk ratings. This study provides experienced workers’ opinions regarding factors that might magnify the risks resulting from DoC scenarios. The study is unique in that construction workers’ feedback has been utilized and analyzed using the Delphi method. Project planners and safety risk managers may benefit from the ratings of the various factors when undertaking planning and preparation activities before and during construction. © 2020, King Fahd University of Petroleum & Minerals. | Springer Science and Business Media Deutschland GmbH | 2193567X | |

Most methods of design the jet-grouting column based on experience. In this study, a prototype single and group jet grouting models (single, 1∗2, and 2∗2) with the total length and diameter were (2000 and 150 mm) respectively and clear spacing (3D) has been constructed in soft clay and subjected to vertical axial loads. Furthermore, different theoretical methods have been used for the estimation of (JGC) settlement. Pile load settlement analysis of the jet grout columns showed that the average settlement values were (0.41, 0.663, and 1.5 mm) for the single, group (1∗2) and group (2∗2) jet grouted columns respectively. While, in the theoretical methods give a higher value of the settlement (2.0, 3.48, and 5.24 mm) for the single, group (1∗2) and group (2∗2) jet grouted columns compared with the settlement results acquired from field pile load test data. Therefore, it is not recommended to be used for soft clay. On the other hand, Fuller and Hoy's, Hansen's 90%, and Butler and Hoy's results may be considered faithful interpretation methods for the single and group (1∗2 and 2∗2) (JGC). © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

Internal sulphate attack takes place due to the source of sulphate being incorporated into the concrete at the period of mixing, while adding gypsum in the cement etc. This project aims to investigate the influence of internal Sulphate Attack (ISA) on some characteristics of light weight (LWC) and normal concrete (NC). In this study, two types of concretes have been prepared, light weight and normal concrete. Two levels of sulphates (3% and 6%) are added as a part of sand to determine the influence of sulphates on NC and LWC that produced a local material and compared it with control normal mix. These added ratios of sulphate are highly convergence of the actual reality of internal sulphate. To decrease the harmful effect of internal sulphate coming from 3 and 6% by weight of sand, two ways have been utilized in this study. First one, using type I cement with 20% of silica – fume as replacement with a part of ordinary cement, second one by SRPC instead of type I is preferred to resist internal effect of sulphate. Light weight concrete has been prepared by total replacement for gravels by crushed bricks. As a result of this research, it concluded that the increment of SO3 amount caused a decrement in the compressive strength by 43.81% at 90 days and by 33.5 % at 60 days but there is a slight effect appear at 28 for samples consist of OPC with presence of 3% SO3. When sulphates increased to 6%, compressive strength decreased by 49.3% at 90 day, and by 38.3% at age of 60 days with very slight effect at age of 28 days. Tensile strength of NC follows same the behaviour as that of the compressive strength. For light weight concrete, the reduction in compressive and tensile strength will result from combined effect of the ettringite formation and high porosity due to introducing crushed bricks as total replacement for gravels. LWC was highly effected by sulphate attack even at early ages and it concluded that the increment in the SO3 amount by (0-3) % by weight of sand, the compressive strength of LWC, decreased by 20.11 % at age of 28 days, 29% at 60 days, while they decreased by 44 % was at 90 days. Using of 20% silica fume with type I cement heals the effect of 3% and 6% calcium sulphate in the A4 and A5 samples and produced a compressive and tensile strength approximately equal to that of control samples. Using of SRPC with 3% and 6% calcium sulphate in the A7, A8, L7 and L8 samples prevented the effect of internal sulphate in both NC and LWC and gave compressive and tensile strength higher than that of standard samples (without sulphate). © 2020.

Hence, we posit that ensuring fairness in multimodal cyber-bullying detectors (e.g., equal performance irrespective of the gender of the victim) is an important research challenge. We propose a fairness-aware fusion framework that ensures that both fairness and accuracy remain important considerations when combining data coming from multiple modalities. In this Bayesian fusion framework, the inputs coming from different modalities are combined in a way that is cognizant of the different confidence levels associated with each feature and the interdependencies between features. Specifically, this framework assigns weights to different modalities not just based on accuracy but also their fairness. Results of applying the framework on a multimodal (visual + text) cyberbullying detection problem demonstrate the value of the proposed framework in ensuring both accuracy and fairness. © 2020 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The finite element method (FEM) by COMSOL environment was used to investigate the properties and sensing performance numerically. The sensor is made from photonic crystal fiber surrounded by a layer of noble metal. The effect on the outer surface of the PCF of various selective noble metals (gold, silver and copper) used to efficiently generate surface plasmon resonance (SPR) has been studied. A high wavelength sensitivity with a limit of 5000 (nm/RIU) was achieved for different refractive index of analyte. The simulation results indicate that closing holes to the center of the sensor have high influence on the sensitivity of the refractive index, where the wavelength sensitivity and the peaks values in the behavior of the losses curves were increased. For all tests, the relation of wavelength of resonant with the refractive index of analyte was linear, meaning that the sensor could be used for a wider range of refractive index of analyte. Realized amplitude sensitivity reaches 1 300RIU-1 at h=5.5µm. Using the same value of h will make the wavelength sensitivity in presence of gold better than the other elements, while the presence of copper is the best in term of amplitude sensitivity. © 2020, Anka Publishers.

All the events have a similarity in the intensity time profile, they fit under the gradual type and associated with halo coronal mass ejections CMEs and three of them were associated with a solar flare. The acceleration of the impulsive phase should be a result of coronal shock due to investigations of the radio type II emission and the gradual part as a result of interplanetary shock, which caused a D-H radio emission. The record of the shock waves by (Charge, Element, and Isotope Analysis System) CELIAS onboard SOHO did not appear for two of those events although all the evidence suggested that there were strong shocks associated with those SEP events at the sun and interplanetary IP medium beside auroral observation at earth were seen in association of the arrival time. The observations suggested that the shocks that did not see on CELIAS were decelerating and gradually the mean free path of them reach the IP medium and the shocks dissolve in IP medium before passing SOHO but the characteristics of the intensity time were not online with this suggestion since acceleration were continued. We suggested that the magnetic field in the IP medium played a rule in changing the shock wave direction and hence it did not pass the spacecraft. © 2020, Anka Publishers.

Pyrolysis is one of the thermal treatments for biomass wastes that results in the production of liquid, solid and gaseous products. Unfortunately, the complex structure of the biomass materials matrix needs elevated heating to convert these materials into useful products. Microwave heating is a promising alternative to conventional heating approaches. Recently, it has been widely used in pyrolysis due to easy operation and its high heating rate. This review tries to identify the microwave-assisted pyrolysis treatment process fundamentals and discusses various key operating parameters which have an effect on product yield. It was found that several operating parameters govern this process such as microwave power and the degree of temperature, microwave absorber addition and its concentration, initial moisture content, initial sweep gas flow rate/residence time. Moreover, this study highlighted the most attractive products of the microwave pyrolysis process. These products include synthesis gas, bio-char, and bio-oil. The benefits and challenges of microwave heating are discussed. © 2020 by the authors. | MDPI AG | 22279717 | |

Following replication, CoVs assemble on intracellular membranes including the endoplasmic reticulum Golgi intermediate compartment (ERGIC) where the envelope protein (E) functions in virus assembly and release. In consequence, E potentially contains membrane-modifying peptides. To search for such peptides, the E coding sequence of Mouse Hepatitis Virus (MHV) was inspected for its amino acid conservation, proximity to the membrane and/or predicted amphipathic helices. Peptides identified in silico were synthesized and tested for membrane-modifying activity in the presence of giant unilamellar vesicles (GUVs) consisting of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), sphingomyelin and cholesterol. To confirm the presence of membrane binding peptides identified in the context of a full-length E protein, the wild type and a number of mutants in the putative membrane binding peptide were expressed in Lenti-X-293T mammalian and insect cells, and the distribution of E antigen within the expressing cell was assessed. Our data identify a role for the post-transmembrane region of MHV E in membrane binding. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

This study is chiefly based on density functional theory calculation, which is implemented in the wien2k code. In fact, we calculated the electronic properties such as electronic band structures, band gaps, DOS, formation energy, and electrical conductivity of three types of monolayers Stana-Silicene; (SnSi, SnSi3, and SnSi7) with various concentrations (50%, 25%, and 12.5%) of the Sn and the Tin atoms. By computing the formation energy of these materials within various concentrations of the Sn atoms, we observed that the SnSi monolayer has more stability than SnSi3 and SnSi7. Another important result is that the electrical conductivity of SnSi depends on the concentrations of the Sn atoms. Indeed, it increases by increasing the concentration of the Sn atoms. By using various concentrations of the Tin atoms, we found out that all these nanomaterials behave as a semiconductor material within direct electronic band gaps. © 2020, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

These bran fractions were incorporated into pasta at 1, 5, 10 and 20% and the phytochemical and technological properties evaluated. Higher incorporation of bran, especially at 20%, reduced pasta quality, but a reduced impact was seen at the same degree of incorporation using finer bran. Bran increased antioxidants (by up to 65%), ferulic acid (up to 400%) and phytosterols (up to 130%) in pasta, parameters which were insensitive to bran particle size above 10% incorporation except for ferulic acid, which was higher in particles between 248 and 1497 μm. It is recommended to use finer fractions if bran is added to pasta at 20% and higher, since they provide a better quality pasta while still delivering enhancements in phytochemical content above regular semolina pasta. © 2020 Elsevier Ltd | Academic Press | 7335210 | |

Here, the electrical and thermoelectric properties of metallocenes containing divalent ions Fe, Ni, and Co (ferrocene, nickelocene, and cobaltocene) were investigated. This was achieved by calculating the electronic and phononic transmission coefficients together with the electrical conductance and Seebeck coefficient. The analysis results suggest that the electrical conductance can be tuned by metal substitution, and the thermal conductance due to the electrons across this family of molecules take the order nickelocene > ferrocene > cobaltocene. In contrast, the contribution of phonons to the thermal conductance of these junctions is very insensitive to the selection of the metal atom. Metal substitution has the potential to change both the sign and the amplitude of thermopower. © 2020, The Minerals, Metals & Materials Society. | Springer | 3615235 | |

The latter two theories are implemented in the wien2k code and Boltztrap package, respectively. We detected that the behaviors of these 2-D nanomaterials are both affected by and dependent on the sites of the C and Si atoms in the SiC structures. Our results demonstrated that T1 is a semiconductor nanomaterial with direct electronic band gap; but the second type of the SiC (T2) is a conductor nanomaterial. Furthermore, we found out that the optical properties of these 2-D nanomaterials are also influenced by the positions of the C and Si atoms in the T1 and T2. Another significant result is the electrical conductivity. The T1 has a better electrical conductivity comparing it to T2. In brief, we predict that T1 will be very useful in various applications such as being used to create solar cells, nano-devices, transistors and phototransistors. © 2020 | Elsevier B.V. | 92614 | |

Methods and Results: Various bacterial species have been demonstrated to involve in human cancers. However, the data is not enough for better understanding of predominant specific species. Application of a rapid and early-diagnostic, cost-effective, non-invasive, and inclusive method is a crucial approach for obtaining valid results. The role of Helicobacter pylori (H. pylori) in gastric and duodenal cancer has been confirmed. From investigation among previous publications, we attempted to make it clear which bacterial species significantly and specifically increase in various cancer types. It was unraveled that there is significant change in Granulicatella adiacens (G. adiacens) in lung cancer (LC), Fusobacterium nucleatum (F. nucleatum) in colorectal cancer (CRC), H. pylori and Porphyromonas gingivalis (P. gingivalis) in pancreatic cancer, and Streptococcus spp. in oral cancer. Conclusion: Alteration in the cell cycle by means of different mechanisms such as inflammation, alteration in cell signaling, invasion and immune evasion, specific niche colonization, induction of DNA damage and mutation, expression of some microRNAs, and enhancing epigenetic effects are the most common mechanisms employed by bacterial species. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 19416628 | |

Additionally, there is an osmotic effect on salty water flow in porous concrete. However, so far, a fully profound understanding of the coupled cyclic wetting–drying and osmosis effects on the chloride movement in concrete is still limited. This paper reports on a comprehensive study on the topic. A series of experimental tests was conducted initially for the vapour-water sorption isotherm (VWSI) of normal concrete of different porosity and chloride content. Thereafter, a novel mathematical model was proposed and validated to characterise the effect of chloride salt on the vapour absorption and water retention behaviour of concrete. Finally, the proposed characteristic model was implemented in a numerical model to simulate chloride ingress in concrete in tidal zones. The vapour-water sorption isotherm model successfully provides an effective tool to quantify the coupled influence of cyclic wetting–drying and osmosis on chloride transportation in concrete. © 2020 Elsevier Ltd | Elsevier Ltd | 9500618 | |

The shape and size of the openings should be chose carefully. While experimental investigation and finite element analysis are difficult to conduct by field engineers, developing a simplified analytical method is important. This study presents an analytical method to examine the effect of opening on the area load capacity of square and rectangular slabs. Two factors were involved in the analysis to take in the account the shape of the slab and the opening. The aspect ratio between the long and short dimensions of slab mentioned by the variable (β), while the aspect ratio between the dimensions of opening is mentioned by the variable (α). The results show that openings have a significant effect on the area load capacity of concrete slabs. In addition, square openings have less effect on the load capacity of rectangular slabs, whereas, rectangular openings have a significant effect on the area load capacity of square slabs. Field engineers can use the presented equations in this study easily and effectively where an opening is required in an existing slab. © 2020 Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

We calculate the spatial distribution of the frontier orbitals, energy gap, transmission probability and the current rectifying ratio for OPI, OPI-pyridine, OPI-pyrazine, OPI-thiophene and OPI-thiazole. The transmission spectra change remarkably depending on the type of side group and torsion angle. The current rectifying ratio will increase by increasing the difference between torsion angles depending on the type of side group. That means the OPI-side group can be employed in molecular electronics. © 2020 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

There are very interesting results. So, the electronic properties are affected and altered. SWBNNTs is very sensitive to the Ce due to it has a higher adsorption energy and total energy with a negative sign, which made the Ce/SWBNNTs is more stable comparing to others nanoparticles. The electronic band gap and the shape of the DOS are changed. Also, there is the smallest value of the chemical hardness, which led to require small exaction energies to transfer electrons. Results demonstrated that all electronic properties of these nanoparticles are enhanced with Ce molecule and became very beneficial in various applications.

The objects of this research is to study the structural behaviour of the branching columns and how it effects on the form-finding. These branching columns are experimentally tested and preparation tables to assist with design of it. Experimental work was carried out on the seventeen specimens. All specimens have been tested under static load then evaluated for maximum failure load, maximum vertical displacement and failure mode. The studied variables are the ratio of horizontal spacing between branches to total width of specimen, number of branches and number of branching level. The results showed that when the ratio between the width of the specimen and the overall width was increased, failure load and buckling load was decreased and maximum vertical displacement was increased. When the number of branches increases, the failure load increases slightly, with the vertical displacement increasing. The failure load, buckling load decreased and the vertical displacement greatly increased as the number of branching levels increases. All specimens have failed with buckling mode, and had less failure load and buckling load than the reference specimen. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

This interest was due topatients researchers, and the medical world seeking for effective solutions to their serious challenges, such as the need to repair or, replace, substitute organs or tissues. In current article, Rentato Panelli mathematical equation utilize to understand and track parameters refer to a physical significant, deformation nature and shape memory degree and of two types of bio-polymer derivative mixtures, Avicel 102 and Sodium Starch Glycolate (SSG). Panelli constants were stated by using combination of two, known, bio polymer in term of deformation and shape memory specifications to validate of the equation parameters to predict this characteristics for unknown materials which may be part of human body or cardiovascular artificial parts. Constants and coefficients for equation measured by applying low pressure ranging from 15 to 75 Mpa. The issues emerging from the findings relate specifically to depth in-die analysis. The most interesting findings was the Panelli equation parameters are perfectly valid in representing bio-polymer characteristics under stress. These parameters and characteristics are able to assess the features of the bio-polymer which sometimes become beyond the scope unless defined by using specific instrumentation. In addition, these parameters can decide the applied pressure that achieve particular density in the manufacturing conditions . These parameters determine process conditions that produce desired biomedical engineering application as bio ink for 3D printing, artificial organs, and drug delivery system which is difficult or rather impossible without use classical methods. © 2020 Institute of Physics Publishing.

Consequently, waste rubber is considered as one of the most waste materials that might cause environmental problems. Incorporating tires rubbers in concrete pavement has been widely studied as one of the promising and sustainable solutions to these current environmental problems. This paper explored the effect of replacing coarse aggregate with waste tires rubber according to their sieve sizes. Three replacement ratios were suggested to substitute the coarse aggregate in concrete of 5 wt. %, 10% and 15%. Two replacement techniques were chosen in order to investigate the rubber particle size. The results illustrated that the compressive strength reduced by 8.5, 51% for 5 to 15 % replacing from all particle sizes. While it shows lower percentage of 0.3 to 11%, 12 to 19% and 7 to 17% for replacing 5 to 15% from sieve #20 to #4.75, respectively. The dry density for all samples decreased slightly with increasing rubber percentage. Furthermore, water absorption ratios of the tested samples were comparable with the reference sample by replacing from each sieve separately. In contrast, it shows higher increase by replacing from all sieves. © 2020 Institute of Physics Publishing. All rights reserved. | Institute of Physics Publishing | 17578981 | |

College of Science, University of Thi-Qar, Iraq | Aspergillus is a fungus and toxins produced by fungi that negatively affect patients’ lives, and recent research has focused on the relationship between different diseases caused by inhaling portions of fungi or fungal spores. There are some complete reports that fully reveal the relationship of Aspergillus fungi by determining the percentage of toxins produced by this type of fungi or their frequency in feed, food, or even clinical specimens, as well as the effect of toxins secreted by fungi on people who have been exposed to these fungi. It was purified from clinical samples, which included sputum, edema, wiping, tissue parts of the lung and other samples such as serum. As an immunological study, in addition to samples of cereals, nuts and homemade cheeses, as well as some other foods and vegetables. In this review, research in scientific research engines was conducted through four science-based data bases using the following keywords (Aspergillus fungi and the toxins they produce) (diseases associated with Aspergillus fungi). Scientific criteria were adopted in this review, and 41 subjects were selected. The results were compared in these articles regarding the presence of mushrooms in Iraqi governorates such as Najaf, Dhi Qar and Basra, as well as the frequency of mushrooms in Iraq and some neighboring countries such as Turkey, Saudi Arabia and Egypt. And Syria during the period 2009-2018 these results were compared with the WHO reports and the permissible proportions in food and feed. It was found that the highest rate of fungi was in Iraq at approximately 89.5%, while in Syria the frequency of fungi was 86.6% isolated, and in Egypt and Jordan it was 70.67% 77.6%, respectively, while in Saudi Arabia the Arabian Peninsula was 50.56% less frequent. The high rate of fungi frequency in Iraq may be due to black storage of foodstuffs, which has led to a high rate of fungi frequency and an increase in the proportion of foodstuffs or in clinical samples, according to the materials under study. © 2020, Institute of Medico-Legal Publications.

PTPN22 (protein tyrosine phosphatase non-receptor type 22) encodes for LYP (lymphatic phosphatase) and it a central passive regulator for T lymphocyte activation. Recent studies have shown the link among gene of PTPN22 variants + 1858C > T and multiple autoimmune diseases. Present research was aimed for investigating the relationship among PTPN22 gene polymorphisms and SLE in southern Iraq. Present research involved 110 SLE patients and 70 as control group from healthy volunteers. Extracted genomic DNA and genotyping was done using (P C R – R F L P) polymerase chain reaction – restriction fragment length polymorphism method. The 1858 T allele frequency showed association (O R = 0.26, CI 95% = 0.14 to 0.48, p < 0.001 with SLE patients relative to control group. In conclusion. The frequency recorded in this analysis of PTPN22 R620W gene functional variable is among the highest in comparison With the other inhabitants of the world, the widespread prevalence of this variable in patients with SLE as compared to controls indicates its important contribution along with other factors to the conferral of SLE susceptibility. The frequency of 1858 T demonstrated a correlation allele in patients with SLE compared to control group in study population. Our study illustrated that there was no correlation between Genotype, Gender` and` Risks of SLE. There was, however a substantial correlation between Age` and Risks of SLE. © 2020, Advanced Scientific Research. All rights reserved. | Advanced Scientific Research | 9752366 | |

The stabilizers in their effect on cohesive soils can be divided into “stabilizers-hydrophobizators” and “stabilizers-hardeners”. The latter, unlike the former, not only reduce heaving processes during freezing of soils, but also sharply change their physical, mechanical, and water-physical parameters. It is possible to expand the boundary of the use of the stabilization method for cohesive soils (from sandy loam to clay with a plasticity number of 27) using a wide arsenal of modern materials, as well as the additional introduction of binders into the system. © 2020 Alpha Publishers.

A finite volume method with the k-" standard model is used to investigate the effects of step, Reynolds number and type of liquid on heat transfer enhancement. Three types of conventional fluids (water, ammonia liquid and ethylene glycol) with Reynolds numbers varying from 98.5 to 512 and three cases for different step heights at a constant heat flux (q = 2000W/m2) are examined. The top wall of the passage and the bottom wall of the upstream section are adiabatic, while the walls of both the first and second steps downstream are heated. The results show that the local Nusselt number rises with the augmentation of the Reynolds number, and the critical effects are seen in the entrance area of the first and second steps. The maximum average Nusselt number, which represents the thermal performance, can be seen clearly in case 1 for EG in comparison to water and ammonia. Due to the expanding of the passage, separation flow is generated, which causes a rapid increment in the local skin friction coefficient, especially at the first and second steps of the downstream section for water, ammonia liquid and EG. The maximum skin friction coefficient is detected in case 1 for water with Re = 512. Trends of velocities for positions (X/H1 = 2.01, X/H2 = 2.51) at the first and second steps for all the studied cases with different types of convectional fluids are indicated in this paper. The presented findings also include the contour of velocity, which shows the recirculation zones at the first and second steps to demonstrate the improvement in the thermal performance. © 2020 by the authors. | MDPI AG | 20738994 | |

Three types of microwave-assisted pretreatments of sago palm bark (SPB) were conducted for enzymatic hydrolysis, namely: microwave-sulphuric acid pretreatment (MSA), microwave-sodium hydroxide pretreatment (MSH), and microwave-sodium bicarbonate (MSB). The experimental design was done using a response surface methodology (RSM) and Box-Behenken Design (BBD). The pretreatment parameters ranged from 5-15% solid loading (SL), 5-15 min of exposure time (ET), and 80-800Wof microwave power (MP). The results indicated that the maximum total reducing sugar was 386 mg/g, obtained by MSA pretreatment. The results also illustrated that the higher glucose yield, 44.3 mg/g, was found using MSH pretreatment, while the higher xylose yield, 43.1 mg/g, resulted from MSA pretreatment. The pretreatment parameters MP, ET, and SL showed different patterns of influence on glucose and xylose yield via enzymatic hydrolysis for MSA, MSH, and MSB pretreatments. The analyses of the interactive effect of the pretreatment parameters MP, ET, and SL on the glucose yield from SPB showed that it increased with the highMPand longer ET, but this was limited by low SL values. However, the analysis of the interactive effect of the pretreatment parameters on xylose yields revealed that MP had the most influence on the xylose yield for MSA, MSH, and MSB pretreatments. © 2020 by the authors. | MDPI AG | 22279717 | |

Materials and methods: This study in a design of a cross-sectional, 92 patients of lichen planus, were enrolled from those patients referred the outpatients clinic of section of dermatology and venereology in Merjan teaching hospital and Alhussein teaching hospital in Thi Qar, Iraq for a period extended from Jan. 2018 to Jan. 2019. Oral colchicine 1 g once daily was prescribed to every lichen planus patients in the study. Duration of therapy extended from one month to three months then follow up for another three months. Response to treatment was reported at every visit. Photographs were taken at both pre and post treatment visits. Results: Out of the entire 92 patients involved in the study, 4 patients withdrew from the study because of gastrointestinal side effects of colchicine, while 3 patients were missed to follow up thus were omitted from the study. Beyond the residual 85 patients 39 were males (46%) and 46 females (54%) (female to male ratio 1.18:1). Age of patients ranged from 19-56 years. The most common type of lichen planus was classical type followed by actinic lichen planus, oral lichen planus was the third in frequency, while lichen planopillaris was the fourth making hypertrophic variant of lichen planus as the least common clinical variant. Enhancement in lichen planus lesions was more noticeable and obvious in patients who were under colchicine therapy for prolonged interval (the full three months). Good improvement (<70% reduction in the severity of lichen planus lesions) was noted clinically in 55 patients forming (64.7%) of all patients in the study. Moderate response (30-70% improvement) was detected in 22 patients forming (25.8%) out of total patients. Otherwise poor response to colchicine therapy (less than 30% improvement in lichen planus lesions) was seen in 8 patients only forming (11.7%) out of all patients in this study. Conclusion: Colchicine seems to be effective drug, safe and good choice for those challenging cases of lichen planus. © 2020, Advanced Scientific Research.

Four polysaccharide biodegradable polymers (guar gum, pectin, starch, and chondroitin) were used which undergo enzymatic degradation in the colon to deliver the 5-ASA in the colon. Granules contain guar gum as biodegradable polymer and probiotic Lactobacillus fermentum were prepared by wet granulation method using different superdisintegrants, different ratio of gum to probiotics and different concentrations of coating material (shellac). The prepared granules were evaluated for flow properties using the compressibility index, also these granules were evaluated for its drug content, moisture content and in vitro drug release. The results showed that guar gum was the best biodegradable polymer, on the other hand Avicel PH-102 was the best superdisintegrant compared to others. The best ratio of gum to probiotics was 1:3 and the best concentration of coating material shellac was 10%. The results illusterated that the presence of bifidobacteria in the formulated granules coated with 10% shellac were able to retard the drug release for 6 hr then they released more than 80% of the drug in buffer of pH 6.8 at the end of 8th hour in the in vitro drug release studies. It can be concluded that the prepared granules of 5-ASA which contain guar gum and probiotic coated with 10% shellac have a good enteric property and may be used successfully for colon targeting to ensure maximum drug release at colon. © 2020, Advanced Scientific Research.

Two different nanofluids are considered. Nanoparticles made of aluminum oxide (Al2O3) and titanium oxide (TiO2) with volume concentrations varying from 0.005 to 0.02 have been examined. Reynolds number and heat flux varied from 10,000 to 40,000 and 1000 to 6000 W m−2, respectively. Area reduction ratios from 1 to 2 were studied in this research. For turbulence modeling, the SST k–ω model in a 3D domain was utilized. In order to validate the numerical results, Al2O3–water-based nanofluid was tested, and a great agreement was observed. It was noted that the maximum thermal performance enhancement was about 194.7% in an annular channel with an area reduction ratio of 2 compared with a straight pipe using water. The heat transfer enhancement is attributed to the downstream flow separation and recirculation region. It was noted that rising the volume concentration of the nanoparticles improves the heat transfer coefficient; this enhancement was about 26.9% (Al2O3) and 5.5% (TiO2). Also, the influence of the Reynolds number on the surface heat transfer coefficient augmentation is quantitatively reported in this paper. The maximum pressure drop was about 7.5% for Al2O3 and 5.9% for TiO2 nanofluid, compared with pure water at a reduction ratio of 2 at the highest Re value considered here. © 2020, Akadémiai Kiadó, Budapest, Hungary. | Springer Netherlands | 13886150 | |

Microwave-assisted pretreatment was found to be a good alternative of conventional heating pretreatment of acid or alkali due to its direct heating of sample which reduce the energy consumption. The present study aims to evaluate the effect of using very diluted solvent (acid and alkali) on monomeric sugar yield during microwave-assisted pretreatment of lignocellulosic biomass (sago palm bark wastes). The changes of the surface structure of untreated and pretreated lignocellulosic biomass were detected using SEM analysis. Three solvents were employed at three concentrations (0.01, 0.05 and 0.1 N). The solvents that utilized in the microwave-assisted pretreatment were sulphuric acid (MA), sodium hydroxide (MH) and sodium bicarbonate (MB) and compared with distilled water (MW). Sago palm bark (SPB) was soaked in these solvents as a substrate at 5% w/v and subjected to microwave power at 800 W in a modified household microwave oven for 5 minutes. Immersing feedstock in distilled water and heating using microwave heating released 5.32 mg/g of monomeric sugar. Highest yield of monomeric sugar was found using 0.1N H2SO4 which yielded 10.28 mg/g during. Applying the pretreatment using the similar concentrations of NaOH and NaHCO3 released 9.35 and 4.31 mg/g of monomeric sugar, respectively. Decreasing chemical solvent level from 0.1 to 0.05 and 0.01 N shows a negative influence on sugar yield for MA and MH pretreatment while MB pretreatment displays a positive effect by extracting some useful components such as xylose. © 2020 Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

These characteristics led many specialists to study and develop this type of renewable energy. This research paper includes simulations for the design of single-diodes solar cells under the influence of different temperatures and saturation conditions to demonstrate the efficacy of the solar cell. It is also known that the solar cell must be linked to a power controller and here it will be used as an artificial neural network (ANN) technology which is the nonlinear autoregressive moving average (NARMA) by using MATLAB program to control the output power of the PV cell.

Specifically, we consider two populations of excitatory neurons where each population is responsible for a direction of movement, say, right and left. Both the excitatory neuron populations are connected to an inhibitory neurons population. Each excitatory population wants to take control of the movement. We formulate a game theoretic view of this competition. Specifically, we assume that the activity level of each neuronal population is quantized in to two levels. We transform the dynamical system model that exists in the literature, see for example [1], for this problem to create the game utilities. We characterize, through the replicator dynamics of the evolutionary game, the evolutionary stable strategies and find conditions under which they hold. Finally, we use the phase portrait to show the evolution of the evolutionary stable strategies from different initial conditions. We find that mixed strategies cannot be a part of the game solution. In addition, we find that the case of no or low activity is the worst case and there are no initial conditions or neurons coordination that can overcome it. © 2020 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The whole edifice of contemporary science stands on the shoulders satellite communication interconnected theories. The ionosphere has crude arguments. The ionosphere is a giant layer that extends from 80 to 1000 km above Earth. The ionosphere contains free electrons and ions. These particles contribute to disturb the propagation of the electromagnetic waves that pass through the ionosphere. These particles could refract or disperse the electromagnetic waves that pass through the ionosphere. This paper will study the impact of the reflection and the absorption in the ionosphere for the propagation of the electromagnetic waves and what is the relation among them. The comprehension of absorption of the ionosphere is coming from VOACAP model.

Ebola infection is viewed as a feature of the Filoviridae family (filovirus). Ebola infection comprises of five unmistakable species: Bundibugyo (BDBV), Zaire (EBOV), Sudan (SUDV), Reston (RESTV), Taï Forest (TAFV). In this paper, after sorting Ebola viruses-based type, we divide Ebola virus into two groups: severe and non-severe. Zaire and Sudan belong to most severe virus in terms of fatality.While Bundibugyo, Tai Forest and Reston are categorized as non fatal group. We found that 1-78 and 2974-3018 ranges are the most common nucleotide parts for severe group (Zaire and Sudan). And this range belongs to the NP range in Ebola virus. We also found that three least dangerous viruses in non-severe group have high nucleotide similarity with three match ranges. And finally, no strong similarity exists between the most severe virus Zaire and the least severe virus Reston. © 2020 Alpha Publishers. All rights reserved. | Alpha Publishers | 19044720 | |

Water and chloride contents in concrete are highly variable in RC structures in real-world hostile environments, meaning that characterisation of their coupled effects on concrete electrical resistivity is important. The currently available models are investigated in this paper. As all the current models are purely empirical, an improvement with a semi-empirical model is proposed. The improvement highlights the intrinsic linkage between concrete electrical resistivity and water content and the pore size distribution of concrete. The proposed model was tested using two sets of experimental data and was also compared with other two empirical models. © 2020 ICE Publishing. All rights reserved. | ICE Publishing | 249831 | |

Therefore, the purposes of this study were to determine the effects of exercise and abuse of synthetic anabolic steroids and food supplements on micronuclei frequency in buccal cells and 8-hydroxy-2-deoxyguanosine (8-OHdG) as markers for DNA damage. Methods: The study included one hundred males aged 17–44 years, distributed into five distinct groups including Group I: 20 bodybuilder individuals with AAS consumption, Group II: 20 bodybuilder individuals with diet supplement (proteins) consumption. Group III: 20 bodybuilders without AAS and diet supplement (proteins) consumption, Group IV: 20 football players without AAS and proteins consumption, and Group V 20 non-athletes without diet supplement or AAS consumption. Results: The mean age + standard deviation (SD) of groups I, II, III, IV and V were (27.00 ± 5.53, 27.85 ± 5.60, 29.70 ± 8.04, 22.35 ± 3.89 and 26.05 ± 6.42, respectively. The mean of BMI values was significantly different among groups (p <. 0001), being much higher for the group I (26.77 ± 1.64) than for group V (22.78 ± 1.53***). Notably, group I and II exhibited elevation in 8-OHdG concentration (3.19 ± 0.35 and 3.28 ± 1.66, respectively) compared to those from the other groups, not being statistically significant. In addition no statically difference was observed according to frequency of micronuclei in buccal cells. Conclusion: Our results outlined that exceeded usage of AAS or food supplement (proteins) exerted no increasing effects of oxidative DNA and/or chromosomal aberration accounting for serum 8-OHdG and micronuclei in buccal cells. These are possibly due to the adaptive responses such as up regulation of DNA repair systems and enhancement of the anti-oxidant capacity in highly-trained individuals. © 2020 | Elsevier B.V. | 22145400 | |

This study experimentally investigated the effects of various configurations of inlet restrictors (IRs) on the thermal hydraulic performance of flow boiling in a microchannel heat sink, which has a single rectangular microchannel with an aspect ratio of 13.12 and a hydraulic diameter of the 708 µm. The experiments were carried out for the microchannel with three designs of inlet restrictors: one-slot opening (1IR), three-slot openings (3IR), and five-slot openings (5IR), for mass fluxes of 32.68, 81.29 and 144 kg/m2 s, respectively. The effects of the various IRs on the CHF, average HTC and pressure drops of the microchannel heat sink were analyzed. The results showed that all test cases with IRs improved the CHF performance of the flow boiling microchannel heat sink, where the 5IR case works best at low mass flux and the 1IR case works best at high mass flux. The results also illustrated that the IRs reduce the HTC at low mass flux, but improve the HTC at high mass flux and heat flux. IRs always exhibit higher pressure drop penalties. This study also revealed the optimum design for microchannel with IRs, which depends on the operational parameters (e.g., mass flux and heat flux) of the microchannel heat sink. © 2020 | Elsevier Ltd | 179310 | |

The mechanism of electron mobility through DNA is important to study DNA-based molecular electronics in nano-bioelectronics. In this study, the influence of number of base pairs on transmission probability, conductance and current for a DNA system has been investigated by using a tight-binding model. Two DNA sequences, (G/C) and (A/T), was studied using the steady state formalism. One active region of DNA molecules assumed to be represented by a fishbone model. The behavior of transmission spectrum (T) was discussed for both DNA sequences as a function of the number of base pairs (N). In addition, a nonlinear behavior of the current (I) was found by studying I-N curves. Further, the resistance-dependent of number of base pairs is also discussed to describe the resistance behavior and values for both DNA sequences. It demonstrates that the resistance-dependent of number of base pairs represented by nonlinear dependent with small different in its values, and the two DNA sequences gives different R-N curve characteristics. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

General formula for the transmission probability for electron transfer through Guanine Molecule is derived. Guanine molecule is assumed to be as one active region connected between two leads. In the transmission calculation, three different locations of the onsite energy were noticed due to the change of the gate voltages applied on the molecule. Also, the (I-V) curve characteristics of Guanine was obtained by using tight binding model and steady state. The current as a function of gate voltage, that is varying between-4 to 4 eV, is also investigated. It is found that the current arises and vanishes at different gate voltage values to show gate switching states. Further, the relationship between different gate voltage values and different bias voltage values was presented to show the logic gate behavior. Moreover, conductance as a function of temperature study was stated. It shows two current behaviors, independent and strong dependence on temperature value, that changes the leads energy. These properties can be effectively used for molecular electronic devices. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

In this article, the power quality in three phase system is maintained with a good performance by eliminating the harmonics in the utility power supply by using SAF. The SAF is acting as a current source that injects equal harmonic components but opposite at the PCC. The MATLAB-Simulink toolbox is used to implement SAF with different control techniques, which are the modified instantaneous current components (method, and the instantaneous active and reactive power (PQ) method for controlling the harmonics. The compensation is conducted by using PI based controller.

The energy assessment tools such as a model for forecasting building energy consumption is based on outdoor thermal conditions, the outdoor conditions are highly nonlinear in real life cannot be represented by linear differential equations and have an uncertain disturbance nature. This paper contrives a novel nonlinear model structure to cope with such difficulty, which is composed of two hybrid nonlinear forms, Takagi-Sugeno fuzzy system (TS-FS) and Neural Networks’ Weights. Such a structure has many advantages, including suitability for multi-layer implementations like an integrated eight-dimension net of parameters and weights which represents model input-output relations of a nonlinear system. The Gauss-Newton algorithm is used to tune model weights and parameters for the fitting of nonlinear regression of clusters model to data. The main feature of the proposed model is to express the dynamic conditions of the outdoor thermal environment of each fuzzy implication by a cluster functions model and thus promote the prediction performance. The overall proposed model is tested on the training and validation of multizone then compared with the RLF model. The corresponding results show that a better hybrid modelling and uncertainty mitigation which is achieved without significant loss of prediction accuracy. © 2020 Elsevier Ltd | Elsevier Ltd | 22106707 | |

This study focusing on HPV sperm infection and its effect on sperm DNA integrity and its impact on seminal fluid parameters and may it can help toclarify some reasons of idiopathic male infertility.The total number of males included in this study was (n=154), 104 of them were infertile patients while the other 50 males were fertile healthy control males, with mean age of 29.95±0.68 and 27.58±0.51 years respectively, who attended the infertility center/Al-Hussein Teaching hospital, from october 2016 to January 2018. All patients submitted full reports about their medical status history, in addition to their infertility type (primary or secondary). Specimens of seminal fluid were collected for study from all patients and control. Semen samples were collected by masturbation after 3 days of sexual abstinence. Seminal fluid was analyzed (seminogram) to evaluates certain sperms parameters according to WHO laboratory manual for the examination and processing of human semen, (fifth edition). After that all patients and control group were tested for the presence of anti-sperm antibody (ASA) in their seminal fluid by using method (ELISA). Patients with positive antisperm antibody were tested by nPCR for detection of HPV in extracted sperm DNA based on detection of HPV E gene, trying to find a relationship between infection with HPV and formation and development of anti-sperm antibody. The patient’s specimens with negative anti-sperm negative were further tested by ELISA method to detect the presence of anti-HPV-IgG antibody and comet assay (single cell gel electrophoresis) is used to evaluate sperm DNA fragmentation, then all the samples were tested by nested PCR for detection of HPV-E gene in the extracted sperm DNA. The patients who have positive HPV-E gene result by nPCR were further tested by real time PCR based on detection of L1 gene to detect the genotypes of HPV-16, HPV-18. Regarding the type of infertility in this study, the primary type of infertility was the more frequent type (83.65%) compared to secondary type of infertility (16.34%), and according to statistical analysis, the difference was significant (P < 0.05) between two types of infertility.Seminal fluid analysis in this study showed there were no significant differences (p>0.05) between patients and control group in (pH, percentage of normal sperm morphology and color) indicators. While there were significant differences (P < 0.05) observed in each of semen volume, total sperm count, sperm count per ml, sperm vitality, viscosity, liquefaction time and sperm motility. The overall prevalence of ASA in seminal plasma among studied population was 16.23%.Among infertile patients anti-sperm antibody was positive in 21.15% compered to 6% among healthy control group.Regardingthe ELISA test for detection anti-HPV-IgG antibody, the overall prevalence of anti-HPV-IgG antibody was 10.07%. whereas anti-HPV-IgG detected in 14.63% (12/82) of infertile males compared to 2.12% in healthy fertile males) seminal fluid with test sensitivity of 41.66% and specificity of 90.0%. The result of comet assay for detection of sperm DNA damage among studied population indicated that, none of fertile healthy males gave a positive comet assay, While 14.63% of infertile patients showed comet assay positive result with sensitivity of 83.33% and specificity of 97.14%.The precence of HPV was estimated by molecular method nPCR to detect the presence of HPV-E gene in extracted sperm DNA of patients with infertility and control group, HPV-E gene was detected in l4.63% of infertile patients. While (85.36%) have negative HPV-E gene results. in comparison, none of normal fertile males showed positive result of HPV-E gene (0%). The differences between both groups was statistically significant (p<0.05).In this study, the HPV-16 genotype was the most frequently detected genotype (50%) whereas HPV-18 genotype was (25%) and the other genotypes of HPV was accounted for (25%).Seminal HPV infection is found in a significant proportion of infertile patient in Thi-qar governorate, and it may have considered as a risk factor of male infertility due to sperms DNA integrity changes by HPV infection that leads to immunological and spermatogenesis environment alteration which is quite evident with HPV genotypes (16 and 18). © 2020.

It has been shown that both male and female can make antibodies that react with human sperm and it should, therefore, be considered as a potential fertility parameter. The subjects of this study were from Thi-Qar province where the study was conducted at the infertility unit at Hussein Teaching Hospital in Thi-Qar, south of Iraq,during the period from Aug 2017 to May 2018. Therefore, the aim of this study was an investigation of the levels of Anti-sperm antibodies in infertile men and to determine the roles of the presence of some biochemical parameters (Testosterone hormone, Follicle stimulating hormone, Luteinizing hormone and prolactin hormone). Seventy infertile men aged(22 -36) years and thirty-five fertile men of the age (21-36) year were included in this study as a control group, had not taking any oral drug from three months prior to the study.The patients were divided into two groups (primary and secondary infertility). Seminal fluids and blood serum were collected from each group. All semen samples were collected following (3-5) days of abstinence.presence of antisperm antibody was estimated in the seminal plasma by ELISA sperm antibody kit method. Out of 70 infertile men, antibodies were observed in 40 men of primary infertility and 16 men of secondary infertility. The conclusion of this study was observed there is relationship between ASA and some reproductive hormones. © 2020. All Rights Reserved. | Connect Journal | 9725075 | |

Also investigated phenotypic correlations between the milk compositions traits was observed along with prediction of protein and fat. The highest percentage of protein, fat and solids-not-fat (SNF) in milk were in Awassi sheep (5.10, 5.55 and 9.015, respectively), and the highest total solids (TS) and lactose were significantly in local goats (14.0%) and Frisian cattle (4.64%) respectively. All phenotypic correlations between milk constituents in cattle were positive except between SNF and protein (-0.59). The correlations in sheep were in 0.11- 0.99 range and 0.14 - 0.80 range in goats between milk compositions traits. The prediction equations of protein were with high 79, 88 and 99% in cattle, sheep and goats respectively indicating that protein percentage could be predicted from TS and SNF in high accuracy. The R2 s of fat was very low in all three species which reflecting the inability to rely on TS and SNF to predict the percentage of fat in milk. © 2020 Ecological Society of India.

The sample includes 75 patients who were attending Al-Nasiryiah heart center, during the period from December 2017 to March 2018, with 41 healthy as a control group. The result indicated a significant increase (at P≤0.05) of TG,HDL and VLDL in VSD patients compared with the control group. while non-significant differences in Cholesterol and LDL in VSD patients compared with the control group. The results showed a significant increase (P≤ 0.05) of ALT, AST, ALP (at P≤ 0.05) in VSD patients compared with control. This study was conducted to identify the potential association of GATA4 gene SNPs with the progression of the ventricular septal defect (VSD) in Thi-Qar province in Iraq. One genetic locus covering 478 bp within the intronic region of the GATA4 gene was amplified and sequenced from both termini. Out of 20 sequenced samples in this locus, only one SNP was observed, namely rs10503425,which was found to be known with its association with VSD. The online available records of this SNP has indicated its pathological correlation with the progression of this congenital disease. The current results indicated that the distribution of the observed rs10503425 was only found in 6 examined samples, including samples no. 7, 10, 13, 14, 17, and 19. In conclusion, this observation may unmask more confirmation about the particular involvement of this discovered SNP in the progression of VSD in Thi-Qar population. © 2020, Advanced Scientific Research.

Currentstudyhas been done in order to determine QTD in patients with stable angina, assess myocardial ischemia and infarction. Aims of Study: This study aiming to determine the relationship between severity of coronary artery disease (CAD) and degree of QTD. Patients and Method: A 214 patients (177 men and 37 women) underwent diagnostic coronary angiography because of suspected CAD. Standard resting 12 lead electrocardiogram (ECG) were recorded within 24hrs before coronary angiography. QT intervals were measured manually by ruler method and QTD were gauged as (QT maximum – QT minimum). A 184 patients had CAD and control group (30 persons) had a normal coronary angiogram Interestingly, QTD has increased significantly as there was sever increment of CAD. QTD was in 1 vessel disease, 2 vessel disease, in 3 vessel disease, and in left main stem disease. Left ventricular dysfunction has raised QTD significantly in patients with 1,2 vessels, as well as left main stem disease. QTD clearly elevated as Gensini score increased. Involvement of proximal left anterior descending artery did not increase QTD significantly in patients with CAD. Multiple regression analysis demonstrated that severity of CAD, left ventricular dysfunction and previous myocardial infarction were independently associated with increased QTD. QTD increased significantly in patients with stable angina compared to the controls. Severity increase of CAD resulted in significant increase in QTD, and presence of LV dysfunction has caused further increase. © 2020, Indian Journal of Forensic Medicine and Toxicology.

However, none have used PCR to investigate the genetic containing of the virus in this particular area. Therefore, this project intends to detect the presence of hepatitis B using molecular methods and determine the accuracy of the available routine serological methods. The project was performed during the period between September 2017 to January 2019. The Samples have been collected from Dhi-Qar hospital clinical lab, in the province of Dhi-Qar, Iraq. The study has examined 135 patients that have been sending by the internal medicine clinic to the lab to be tested for the possibility of having hepatitis. ELIZA technique has shown that 99 (73.3%) of the patients were tested positive for hepatitis, while 36 (26.6%) are negative. Additionally, the study detected the male sex bias nature of the disease represented by 73 men infected while only 26 women were diseased in the present study. Moreover, aging was one of the factors that reduce the defense mechanism of the disease. Interestingly, PCR test has shown that seven men and ten women patients were positive while they been considered negative by ELISA. My study suggests using the PCR technique in the clinic lab as it can detect the presence of the nucleic acid in a fast and more accurate way. © 2020, Advanced Scientific Research.

Guidelines suggested confirming the benignity of AI radiologically and excluding hormonal dysfunctions. This study evaluated the reliability of computed tomography (CT) scan radiological parameters in predicting the functionality of AI. Patients and Methods: A cross-sectional study performed in Faiha Specialized Diabetes, Endocrine and Metabolism Centre from July 2017 to July 2018, involving 38 patients (23 females [60.5%]) harbouring 43 AI referred for evaluation. For all patients, we assessed history, physical examination, radiological parameters of AI by CT scan (native Hounsfield unit [HU]), maximum diameter and absolute percentage washout [APW] and blood investigations (glycated haemoglobin, adrenocorticotropic hormone, aldosterone, renin, aldosterone/renin ratio, normetanephrine, metanephrine, dehydroepiandrosterone sulphate, cortisol and 1 mg overnight dexamethasone suppression test). Results: Native CT adrenal HU ≥18.5 was statistically significant seen in most functional AI (FAI) (P = 0.006), especially in patients with mild autonomous cortisol excess (MACE) and pheochromocytoma (PCC) with P = 0.02 in both. Maximum diameter was significantly high (≥40 mm) in PCC and congenital adrenal hyperplasia (CAH) (P = 0.018 and 0.008, respectively). APW was significantly < 60% only in PCC (P = 0.02). Conclusions: Native HU was the most significant radiological parameter in predicting the functionality of FAI, MACE and PCC, but not in CAH and aldosterone-producing adenoma. The maximum diameter was significant in predicting the PCC and CAH, whereas the APW was significant in predicting PCC only. | NLM (Medline) | 11171936 | |

Let G = (V,E) be a finite, simple and undirected graph without isolated vertices, a subset D of V is a pitchfork dominating set if every vertex v D dominates at least j and at most k vertices of V-D, where j and k are non-negative integers. The domination number of G, denotes γpf(G) is a minimum cardinality over all pitchfork dominating sets in G. In this work, pitchfork domination when j = 1 and k = 2 is studied. Some bounds on γpf(G) related to the order, size, minimum degree, maximum degree of a graph and some properties are given. Pitchfork domination is determined for some known and new modified graphs. Finally, a question has been answered and discussed that; does every finite, simple and undirected graph G without isolated vertices have a pitchfork domination or not? © 2020 World Scientific Publishing Company. | World Scientific Publishing Co.

Through casting techniques, the composite materials have been prepared. Thermogravimetric analysis (TGA), Fourier Transform Infrared Spectroscopy (FT-IR) and X ray diffraction (XRD) analysis have characterized the preparation of PVA-g-AA composites that found the formation of the composite and the adipic acid presence in polyvinyl alcohol. Studies of DC conductivity demonstrate all composites in thermally activated behavior. Conductance has been found to reduce with increasing temperature showing the semi-conductive behaviour for all doping ratios. With doping ratios in coloring and increasing temperature, the activation energy reduced. Maximum conductance in polyvinyl alcohol has been measured in 0.15% of dye. In sensor technology, Dye sensitization of performing polymeric materials had acquired practical application and wide theoretical interest. The current study provides the effect of polymer presence of dye (conductivity, structure and properties), dye sensitized photo sensors and application in sensors. At the end, advantages and perspectives were included of sensitizing polymers or modifying dye in sensors. © 2020, Advanced Scientific Research.

A short-term disease risk prediction is a challenging task but is a great importance for teleheath care systems to provide accurate and reliable recommendations to patients. In this work, a general extensible learning approach for multi-disease recommendations is proposed to provide accurate recommendations for patients with chronic diseases in a telehealth environment. This approach generates appropriate recommendations for patients suffering from chronic diseases such as heart failure and diabetes about the need to take a medical test or not on the coming day based on the analysis of their medical data. The statistical features extracted from the sub-bands obtained after a four-level decomposition of the patient's time series data are classified using a machine learning ensemble model. A combination of three classifiers – Least Squares-Support Vector Machine, Artificial Neural Network, and Naive Bayes – are utilized to construct the bagging-based ensemble model used to produce the final recommendations for patients. Two real-life datasets collected from chronic heart and diabetes disease patients are used for experimentations and evaluation. The experimental results show that the proposed approach yields a very good recommendation accuracy and offers an effective way to reduce the risk of incorrect recommendations as well as reduces the workload for chronic diseases patients who undergo body tests most days. Thus, the proposed approach is considered one of a promising tool for analyzing time series medical data of multi diseases and providing accurate and reliable recommendations to patients suffering from different types of chronic diseases. © 2018 Elsevier B.V. | Elsevier B.V. | 1678655 | |

Sundry studies have shown a nitric oxide role in the regulation of anxiety. The goal of the study was to investigate sodium nitroprusside ability to affect anxiety-like behavior in mice and to compare this effect with the standard anxiolytic drug, diazepam, using both plus maze test and light/dark box test. The results revealed that sodium nitroprusside at a dose of 1 mg/kg had a significant effect on the behavior in both of the elevated plus maze test and light/dark test. However, at higher dose (3 mg/kg), it has significantly increased the anxiogenic-like effect in the light/dark box test. Diazepam at a dose of 2 mg/kg increased the time spent in open arms in elevated plus maze test and that in light chambers of light/dark test. These outcomes suggest that a nitric oxide pathway seems to play an important role in anxiety. Furthermore, sodium nitroprusside at a dose of 1 mg/kg showed a nearly anxiolytic ability, when compared with diazepam. © 2020 University of Baghdad-College of Science.

This work aims to provide a better understanding of the mechanical behavior of mortar under loading (compression, direct tension and flexural moment). In Iraq, there are many cities placed along the Tigris and Euphrates, therefore can be obtained a lot of quantities of river sand that result from cree and clean these rivers which is considered a cheap prices material, it is used in agriculture only. The most of natural sand in Iraq contains high sulfur trioxide (SO3) which is exceed the Iraqi Standard Specifications [IQS No. 45, 1984], it is (0.5 %). This work explains the influence of river sand on the mechanical behavior of mortar which replacement of natural sand. Four groups of specimens have been realized within a water cement ratios of 0.48, 0.52, 0.58 and 0,6. One group is considered as reference: these specimens without river sand, natural sand only. Other groups have been river sand that replacement of natural sand of 25, 50 and 75 %. All manufactured specimens have the following dimensions for cubes (50∗ 50∗ 50 mm), prisms (40∗ 40∗ 160 mm) and bon dog (25∗ 28∗ 70 mm). In this work, some tests are used for materials and specimens for examples sieve analysis and flow test for materials. Compression test, flexural test and bon dog test have been designed for specimens. Finally, the experimental results are presented in relationships, histogram and tables between mechanical properties and the replacement of river sand.

Concrete mixes were prepared using magnetic field treated mixing water and compared with regular concrete mixes that were made with normal (non-magnetized) tap water. Magnetizing the mixing water was performed by allowing the tap regular water to pass through magnetic fields that ranged in magnetic strength between 0.9 and 1.3 Tesla. Water / Cementitious material ratio, curing age, intensity of the magnetic field as well as cement content were used as the main variables that were investigated as to their influences on the behavior of magnetic mixing water concrete as compared to concrete with normal non-magnetized mixing water. Results showed that the workability of concrete has increased slightly compared with tap water mixed-concrete. At different curing ages, compressive strength of concrete was found to improve considerably as a result of mixing water magnetizing. The maximum enhancement of concrete compressive strength was obtained at the maximum magnetic field intensity used, which was 1.3 Tesla. Compressive strength enhancement was found to be more significant at early ages. It was also found that almost similar levels of fresh concrete workability and 28th day compressive strength and were obtained with 7.5% reduction of cement content for concrete samples made with magnetized mixing water as compared to those made with normal non-magnetized water. This cement requirement reduction may promote the potential to use magnetic mixing water as a positive modification towards a more sustainable concrete. © 2020 Author(s). | American Institute of Physics Inc. | 0094243X | |

In each copolymer the low critical solution temperature (LCST) which was observed at (32°C ± 1). The thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) investigations of hydrogels shows that the loss of swelled water starts from (20°C). The swelling behaviors of all copolymers was studied into two ways and at different temperatures, were the best swelled hydrogels are PNIPAAm-co-TUr at (25°C), PNIPAAm at (35°C), and PNIPAAm-co-EDA at (45°C) based on medical cotton as a surface. The ability of water swelling has been varied according to the functions group of the co-monomer and the way of it connection in polymer chain that's due to hydrogen bonding with water. The medical cotton shows a good water swelling surface more than Iraqi fluff and tail cottons. The surface area of these polymers has been determined by Brunauer-Emmett-Teller (BET) were PNIPAAm-co-EDA have the highest surface area (9.357 m2/g), and the PNIPAAm-co-Ur have the lowest one (0.055 m2/g).

However, the sufficient time for observations to achieve a certain level of accuracy is still one of the main concerns for researchers and specialists. In this study, the geometry of a short-sides triangle has been employed to estimate the sufficient observing times of GNSS receivers throughout the online processing services. The short-sides triangle vertices were observed for 24 hours and partitioned into shorter periods of time, then GPS and GLONASS have been processed as well as GPS alone after filtering out the GLONASS observables. Datasets have been processed using online post-processing services, i.e. AUSPOS and CSRS-PPP. A number of propagation error models have been applied to investigate the station accuracy behaviour. the results have revealed that RMS errors of 1 cm can be achieved after two hours for horizontal component and three hours for the vertical component. Furthermore, including GLONASS satellites is playing a role to enhance accuracy especially in short observation times. © 2020 IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

This method has a computational cost less than that of doing those processes sequentially [1,9]. In this paper, a new signcryption scheme is presented. This scheme is similar to that of Zheng signcryption algorithm but it uses bilinear groups and the security of our scheme is based on Computational Diffie-Hellman Problem instead of Discrete Logarithm Problem.

However, salts started to accumulate in high concentrations in the marsh as the MOD water contains high salt concentrations. This study aims to find an optimal outlet location in the west part of Al Hammar Marsh to drain out the water of the marsh back to the (MOD). Hydrodynamic and water quality distribution mathematical models for the marsh were developed to specify the depths of water, flow velocity profiles, and the distribution of salt concentrations in the marsh. The obtained hydrodynamic properties and the quality of the water within the marsh area were used as indicators for selecting the optimal outlet location among five suggested locations at six operation conditions. Results showed that the water depth, velocity profiles, and concentration of the total dissolved solids (TDS) are affected by the location, discharge, the concentration of the TDS of the feeders, location of the outlet, the topographic characteristics at the upstream of outlet, and evapotranspiration. It is found that the third location of the outlet, located at E=699003 and N=3404760, gives the minimum deterioration in the concentration of the TDS, depending on the overall distribution of TDS concentrations. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

The jet grouted soil cement columns in soft is a complicated issue because it depends on a number of factors such as, soil nature, mixture, influence among soil and grouting materials, jetting force of nozzle, jet grouting and water flow rate, rotation and lifting speed. This paper discusses the estimation of shear strength parameters of soil-cement column (soilcrete) in soft clayey soil based on the relationships between the unconfined compressive and split tensile strength for the soilcrete and the effect of the jet grouting and water pressure in the values of cohesion and internal friction. For this reason, theoretical and field work models have been developed. The relation between split tensile and unconfined compressive strength results were used to draw a Mohr's circle and failure enveloped to define the shear strength parameters of soilcrete. According to that, the results indicate that the resistance of the jet grout columns increases by increasing the nominal resistance of the grouting material (cement), water and jet grouting pressure. The shear resistance variables are increased by increasing the unconfined compressive and tensile strength of the jetting column. The value of the unconfined compressive strength ranges from (2.78-5.52 MPa). While the internal friction angle varies from 38° to 44°. On the other hand, the tensile strength is increased by increasing the unconfined compressive strength and ranges from (0.66-1.02 MPa). © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

Abu-Ziriq Marsh, located in the south of Iraq, is chosen as the case study for the application of the proposed methodology. The aim of this study was to assess the ability of using three different models of Artificial Intelligence (AI) techniques: Adaptive Neural-based Fuzzy Inference System (ANFIS), Artificial Neural Networks (ANN) and Multiple Regression Model (MLR) to predict and estimate the discharge of Abu-Ziriq Marsh by depending on flow release from upstream Al-Badaa regulator. Daily discharge of Al-Badaa regulator(QB ) and Abu-Ziriq Marsh(Qz ) were used in this study. The water quantity data, consisting of 720 records of daily data between the years 2017 and 2018, were used for training and testing the models. The training and testing data were randomly partitioned into 515 (70.5 %) and 215 (29.5 %) datasets, respectively. The performance of all models was assessed through the correlation coefficient (R), root mean square error (RMSE) and Nash-Sutcliffe efficiency coefficient (NSE). Results of RMSE, R and NSE for the calibration (validation) of ANFIS model were 4.11 (4.17), 0.87 (0.83) and 0.76 (0.70), respectively. The evaluation of the results indicates that ANFIS model is superior to other models. The identified ANFIS models can be used as tools for the computation of water quantity parameter(Qz ) in Iraqi Marshes. © Published under licence by IOP Publishing Ltd. | IOP Publishing Ltd | 17578981 | |

Because of its strategical and economic importance in addition to tourism, this study is important. In recent years, many of problems had been observed in many structures constructed on marshes soils due to complex collapsible behavior of such soils. The soils of the marshes are considered as weak soil. This fact comes along because of water table being near the ground level or above it which is usually a fine sand and silty sand. The objective of this study is to investigate the effect of silica fume as Nano-materials on the collapsibility of disturbed marshes soils brought up from Alchibayish area (Thi-Qar) Governorate and Alhalfaiya area (Messan) Governorate collected at depth (1.0) m below the natural ground surface. All fundamental tests were performed on these soils. The effect of adding Nano silica fume on collapsibility of marshes soil by using three different percentages by weight of the dry marshes soil (1, 2, and 3) % were studied. The results of single collapse tests marked (3) % of Nano silica fume decreases the collapsibility sharply; more than 50 % of improvement in collapse potential has been achieved at these optimum percent of silica fume as Nano-material. Where considerable reduction is observed in compressibility by (45-50) % for marshes soil. In laboratory tests, results showed that these soils have high collapsibility and that the shear parameters increase when treated with Nano silica fume. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

Samples of Alcaligenes faecalis from burns were nominated for detection and identification according to morphological and biochemical tests, the VITEK-2 Compact System, and molecular sequencing by 16S rRNA. Materials and Methods: Antibiotic susceptibility was ascertained by determining the inhibition length of A. faecalis against three antibiotics from varied classes (based on the VITEK 2), which consequently showed resistance to ceftriaxone (10 mm), high resistance to trimethoprim-sulfamethoxazole (SXT) (8 mm), and sensitivity to imipenem (20 mm). The sensitivity of A. faecalis to Enterococcus faecium, Streptococcus thermophilus, and Bacillus subtilis was determined using Mueller-Hinton agar (MHA) with wells of diffused agar. Results: B. subtilis performed best against A. faecalis isolates compared to E. faecium and S. thermophilus, where the area of inhibition was 28 mm. This study dealt with the enhancement of the inhibition zone of antibiotics (imipenem, SXT, and ceftriaxone) by B. subtilis against A. faecalis. Conclusion: The potentiation of antimicrobial activity was observed by imipenem in combination with B. subtilis (32 mm) and B. subtilis with ceftriaxone antibiotics (20 mm). The inhibition action was not affected by SXT (8 mm). © 2020 JPR Solutions. All rights reserved. | JPR Solutions | 9757619 | |

However, inconstancy and unpredictable amounts of solar radiation are considered major obstacles in designing SAPV systems. Therefore, an accurate sizing method is necessary to apply in order to find an optimal configuration and fulfil the required load demand. In this study, a novel hybrid sizing approach was developed on the basis of techno-economic objectives to optimally size the SAPV system. The proposed hybrid method consisted of an intuitive method to estimate initial numbers of PV modules and storage battery, an iterative approach to accurately generate a set of wide ranges of optimal configurations, and a Pareto envelope-based selection algorithm (PESA-II) to reduce large configuration by efficacy obtaining a set of Pareto front (PF) solutions. Subsequently, the optimal configurations were ranked by using an integrated analytic hierarchy process (AHP) and vlsekeriterijumskaoptimizacija i kompromisonoresenje (VIKOR). The techno-economic objectives were loss of load probability, life cycle cost, and levelized cost of energy. The performance analysis results demonstrated that the lead-acid battery was reliable and more cost-effective than the other types of storage battery. © 2020 by the authors. | MDPI AG | 22279717 | |

The tradition technologies still suffer from two problems: performance and security efficiency. The existing research has serious drawbacks when using public-key mechanisms such as digital signature algorithms. In this paper, we propose Reliable and Efficient Integrity Scheme for Data Collection in HWSN (REISCH) to alleviate these problems by using secure and lightweight signature algorithms. The results of the performance analysis indicate that our scheme provides high efficiency in data integration between sensors and server (saves more than 24% of alive sensors compared to traditional algorithms). Additionally, we use Automated Validation of Internet Security Protocols and Applications (AVISPA) to validate the security procedures in our scheme. Security analysis results confirm that REISCH is safe against some well-known attacks. © 2020 by the authors. Licensee MDPI, Basel, Switzerland. | MDPI AG | 20763417 | |

A high transmission function is obtained under the high pump field. This function is reduced under increasing the probe field due to the Kerr effect. The phase of this function depends on pumping. It is shown that the application of another two fields from the wetting layer (WL)-quantum dot (QD) type is more efficient in obtaining very high diffraction intensity. So, EIG with high diffraction intensity is obtained under a four-field application. Note that, WL-QD field effect is not studied earlier. Neglecting the WL effect reduces the transmission by five times. The diffraction intensity of this system is six times higher than that obtained from a single QD structure. © 2020, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 3068919 | |

However, dynamic studies are rare in this field. Here, we report our measurement of the effects of Ag+ ions on the dynamics of histone-like nucleoid-structuring (H-NS) proteins in live bacteria using singleparticle- tracking photoactivated localization microscopy (sptPALM). It was found that treating the bacteria with Ag+ ions led to faster diffusive dynamics of H-NS proteins. Several techniques were used to understand the mechanism of the observed faster dynamics. Electrophoretic mobility shift assay on purified H-NS proteins indicated that Ag+ ions weaken the binding between H-NS proteins and DNA. Isothermal titration calorimetry confirmed that DNA and Ag+ ions interact directly. Our recently developed sensing method based on bent DNA suggested that Ag+ ions caused dehybridization of double-stranded DNA (i.e., dissociation into single strands). These evidences led us to a plausible mechanism for the observed faster dynamics of H-NS proteins in live bacteria when subjected to Ag+ ions: Ag+-induced DNA dehybridization weakens the binding between H-NS proteins and DNA. This work highlighted the importance of dynamic study of single proteins in live cells for understanding the functions of antimicrobial agents in bacteria. IMPORTANCE As so-called "superbug" bacteria resistant to commonly prescribed antibiotics have become a global threat to public health in recent years, noble metals, such as silver, in various forms have been attracting broad attention due to their antimicrobial activities. However, most of the studies in the existing literature have relied on the traditional bioassays for studying the antimicrobial mechanism of silver; in addition, temporal resolution is largely missing for understanding the effects of silver on the molecular dynamics inside bacteria. Here, we report our study of the antimicrobial effect of silver ions at the nanoscale on the diffusive dynamics of histone-like nucleoid-structuring (H-NS) proteins in live bacteria using singleparticle- tracking photoactivated localization microscopy. This work highlights the importance of dynamic study of single proteins in live cells for understanding the functions of antimicrobial agents in bacteria. © 2020 American Society for Microbiology. | American Society for Microbiology | 992240 | |

The diagnosis of POTA was carried out by FTIR and NMR analysis. Inhibitor performance was investigated using mass loss technique. POTA was acted as a moderate corrosion inhibitor for low carbon steel in 1 M hydrochloric acidic solution with efficiency more than 70%. The inhibitor performance was attributed to the formation of an adsorption layer on the low carbon steel surface. The mechanism of inhibitor adsorption on the low carbon steel surface was according to the Langmuir adsorption isotherm. The value of adsorption heat was within the range of chemical adsorption.

Although these by-products are a good source of various nutritional compounds, they represent the main disposal problem for the food industry. Wheat bran, one of the main by-products of the wheat milling industry, contains more than 15% high-quality proteins. However, these proteins are present in a form which is poorly digested as they are enclosed within a matrix of cell wall polysaccharides. About 15.5 million tonnes of usable protein could be recovered from bran if a commercial extraction process can be made viable. The purpose of this work was to extract protein from durum wheat bran using an alkaline acid method to study its nutritional and functional properties with the goal of using it as a fortifying material in cereal-based foods such as pasta and bread. Findings: Durum wheat bran protein concentrate (WBPC) was prepared by using an alkaline extraction method (pH 9.5 for two hours) followed by isoelectric precipitation (pH 4.2). Chemical, nutritional, and functional properties of WBPC were obtained. WBPC had a protein content of ~61% (protein yield 20.5%–24.8%), containing also lipids, fiber, and small quantities of starch. WBPC was enriched in phytosterols compared to wheat bran (11.59 vs. 5.14 mg/g) with β-sitosterol the predominant (4.37 mg/g). WBPC was also enriched in all the amino acids compared to bran, especially lysine and threonine. WBPC retained some phenolic acids, but at an eightfold lower quantity than in bran and retained about half the antioxidant activity (DPPH) of bran. WBPC showed excellent functional properties in terms of high solubility over a wide range in pH and good water and fat absorption capacity. The main protein components were albumin and globulin proteins. Conclusion: The extraction method used produced a protein concentrate in reasonable yield with high protein content enriched in essential amino acids and phytosterols compared to wheat bran with good functional properties and phenolic acids and antioxidant potential. Significance and novelty: The nutritional and functional properties of WBPC make it a promising ingredient for various food products such as cereal and baked foods, processed meat, and beverages. © 2019 Cereals & Grains Association | Wiley-Blackwell | 90352 | |

The samples of Oil Shale collected from real Iraqi sedimentary rock deposits. Four Reversible Ionic Liquids solvents 3-(triethoxysilyl)-propylammonium 3-(triethoxysilyl)-propyl carbamate (TESAC), (3-(tripropylsilyl)-propylammonium 3-(tripropylsilyl)-propyl carbamate (TPSAC), 3-(trimethoxysilyl)-propylammonium 3-(trimethoxysilyl)-propyl carbamate (TMSAC), 3-(triethylsilyl)-propylammonium 3-(triethylsilyl)-propyl carbamate (TEtSAC)) are derived from carbon dioxide which reacts reversibly with silylated amine molecular liquids to produce ionic liquids. The efficiency of four Reversible Ionic Liquids (TEtSAC, TMSAC, TPSAC, and TESAC) and for mixed Reversible ionic liquid (Binary mixtures) as a selective solvent in the kerogen extraction from oil shale was investigated. The extraction efficiency was found to be more dependent on the basicity strength of hydrogen bond of the RevIL. It was found that higher extraction efficiencies are accompanied with higher hydrogen bond basicity. Four single RevILs and three binary mixtures (RevIL) to extract the Kerogen from oil shale is used. The study shows that the highest Kerogen extraction efficiency of 90.2% and 97.9% respectively, can be achieved by TESAC and (TESAC + TMSAC) respectively. One mixed binary solvent (TESAC + TMSAC) has the highest distribution coefficient, extraction efficiency and selectivity and greatest variation between its density and boiling point and those of Kerogen is selected. Therefore it can be considered as an excellent extracting solvent for Kerogen from oil shale. © 2019 Egyptian Petroleum Research Institute | Egyptian Petroleum Research Institute | 11100621 | |

To evaluate these parameters effects 26 batch experiments were conducted. Which included: NaOH pretreatment (doses: 0, 0.1, 0.2, 0.3, and 0.4 mol/L and durations: 4, 6, 8, 10, and 12 h), TS content (4, 6, 8, 10%), S/I (15, 20, 25, and 30%), and pH (6.5, 7.0, 7.5, and 8.0). Also, the kinetics of biogas production was studied by using three models: first order kinetic, Cone, and modified Gompertz models. It was found that the optimum conditions were: NaOH dose with 0.2 mol/L, NaOH duration for 10 h, TS content with 8%, S/I ratio with 20%, and pH of 7.5. These optimum situations gave the highest production with 616.2, 644.0, 1968.4, 1467.2, and 1488.6 mL/gVS, respectively. Cone model showed the best fit followed by modified Gompertz model and finally first order kinetic model. These results proved the applicability of mango leaves as a good source for renewable methane-rich energy, and the impact of NaOH pretreatment, TS, S/I, and pH on the biogas/methane yield. © 2018, Springer Nature B.V. | Springer | 18772641 | |

Atterberg limits were developed by a Swedish scientist at the early 1900's called Atterberg. These limits could express the consistency of fine-grained soils due to variety of water content. These limits divide the soil into four major states, solid, semi-solid, plastic, and liquid state. According to American Standard for Testing and Materials (ASTM), to check liquid limit and plastic limit tests for a soil, the soil should be dried before the test for preparation purpose. ASTM specified two ways to dry the soil specimens, oven dry and air weather dry and both should give same results. Most of engineers will go with dry oven method to speed up the specimen preparation process assuming there is no any difference between these two methods of drying. In this research, the effect of the drying method has been studied. The results showed that the drying method has a significant effect on the liquid and plastic limits and then on the classification of soils. The soil specimens of this research were brought from all over Iraq cities to ensure studying different soils that could exhibits different behaviors. © 2020 IOP Publishing Ltd.

Clinical manifestations of the infection may range from asymptomatic to chronic. Strongyloides cause hyperinfection syndrome and dissemination in individuals with impaired cell-mediated immunity due to its ability to proliferate within the host that may increase the mortality rate up to 87%. The diagnosis of hyperinfection syndrome is difficult to establish and entails a high level of suspicion. The objective of the present study was to measure the expression level of C-type lectin gene coding to protein biomarker candidates from the excretory/secretory (ES) products of the infective filariform larva that can be used as diagnostic indicators for early hyperinfection syndrome in strongyloidiasis. An experimental study was carried out to induce hyperinfection of L3 larvae of S. ratti in experimentally immunosuppressed Wistar rats using prednisolone, a corticosteroid immunosuppressive drug. Prednisolone treatment resulted in a significant increase in the parasitic intensities. Relative semi-quantitative real-time PCR was performed to compare the expression level of the C-type lectin's gene between treated and non-treated groups with this drug. C-type lectin gene showed significantly higher expression levels in the treated samples. The study concluded that C-type lectin expression level was successfully measured and could be used as a diagnostic biomarker during early hyperinfection syndrome in strongyloidiasis. © Annals of Tropical Medicine & Public Health S498 | Wolters Kluwer Medknow Publications | 17556783 | |

The aim of any speed controller is to take main signal that represent the reference speed and to drive the framework at that reference speed. This paper exhibits the design, simulation and control of synchronous reluctance motor (SynRM). In addition, the motor speed is controlled by utilizing a conventional PID controller that has been used from the cascaded structure. The Particle Swarm Optimization (PSO) was used to find the best parameters of the PID controller. Lead-Lag controller presents from the cascaded controller as the following period of control. The Space vector pulse width modulation (SVPWM) plot has been proposed to control the motor and make the motor work with no rotor confine contingent upon the info parameters that utilization in the simulation. An examination between both of PID tuned and PSO tuned controller affirms that the PSO gives dazzling control highlights to the motor speed and have an edge over the physically changing controller. Thus, this paper present investigation and simulation for the most precise procedures to control the speed reaction and torque reaction of synchronous reluctance motor (SynRM). © 2020. CBIORE-IJRED.

The transport properties of the single pyrene molecule with four configurations are investigated using a steady-state theoretical model. We calculate the transmission probability and the electric current for the structure (1, 8), the structure (1, 7), the structure (1, 5) and the structure (1, 4). By applying a gate voltage on the pyrene molecule, we calculate the thermoelectric properties. The thermoelectric and electron transport properties can be controlled by quantum interference, the contact geometry and the gate voltage. The asymmetric behavior and the splitting of resonances in the transmission spectrum occur due to applying a gate voltage on the pyrene molecule. As a result, the structures (1, 5) and (1, 7) have a maximum value of the figure of merit reaching to 0.8 at the Fermi level. According to the results, the structures (1, 5) and (1, 7) can be act as promising thermoelectric applications in molecular electronics. © 2019 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

Full-scale beams were prepared and tested under four-point static loads to evaluate the effects of damage location in the concrete member, joint location and internal surface coating of the jacket. The results showed that the behaviour of the repaired system is governed by the tensile cracking of the grout and failing of teeth at the joint. The FRP jacket is found to be more effective in repairing concrete members under flexural load when the damage is located at the top than at the bottom of the member. This effectiveness can be further increased by placing the joint of the composite jacket away from the compression zone. Moreover, the provision of epoxy and coarse aggregates inside the jacket surface resulted in better stress distribution and cracks propagation in the grout than the one without. Finally, a simplified fibre model analysis which considers the confined tensile and compressive properties of the grout reliably predicted the flexural capacity of the damaged beams repaired with the FRP jacket. © 2019 Elsevier Ltd | Elsevier Ltd | 2638223 | |

The aim of this research is to develop a new automatic method for EEG sleep stages classification based on a statistical model and weighted brain networks. Methods: Each EEG segment is partitioned into a number of blocks using a sliding window technique. A set of statistical features are extracted from each block. As a result, a vector of features is obtained to represent each EEG segment. Then, the vector of features is mapped into a weighted undirected network. Different structural and spectral attributes of the networks are extracted and forwarded to a least square support vector machine (LS-SVM) classifier. At the same time the network's attributes are also thoroughly investigated. It is found that the network's characteristics vary with their sleep stages. Each sleep stage is best represented using the key features of their networks. Results: In this paper, the proposed method is evaluated using two datasets acquired from different channels of EEG (Pz-Oz and C3-A2) according to the R&K and the AASM without pre-processing the original EEG data. The obtained results by the LS-SVM are compared with those by Naïve, k-nearest and a multi-class-SVM. The proposed method is also compared with other benchmark sleep stages classification methods. The comparison results demonstrate that the proposed method has an advantage in scoring sleep stages based on single channel EEG signals. Conclusions: An average accuracy of 96.74% is obtained with the C3-A2 channel according to the AASM standard, and 96% with the Pz-Oz channel based on the R&K standard. © 2019 | Elsevier Ireland Ltd | 1692607 | |

The aim in this work is to improve the quality of the machined surface of the by controlling the main input parameters of the turning process for aluminum and steel materials. The effect of the machining parameters on surface roughness was studied using the orthogonal L9 Taguchi method. Four process parameters chosen were the length of the specimen (L), diameter of the specimen (D), feed rate (F), and depth of cut (T). The optimization method was performed using the signal to calculate noise ratio (S / N) for the changing response of all experiments. The results were analyzed using the analysis of variance (ANOVA). The main conclusion of this work is that F and T are the most important factors and can influence the machined surface quality in terms of surface roughness, whereas the other factors are insignificant. The minimum surface roughness for aluminum is 1.03 μm and 5.02 μm for steel specimens, which were obtained using a more suitable set of parameters with values of T 0.5 mm, F 0.5 RPM., L1000 mm, and D 40 mm. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

Twisting profiles are utilized in most mechanical fields, including car design, aeronautic design, plant building, fluid transport, heat exchangers and many other sectors. Ovalization affects the nature of cylinder bowing. It occurs in the cross segment of the cylinder in the wake of bowing when the cylinder has twisted without a mandrel, or with a change of mandrel structure. This paper examines the ovalization phenomenon in cylinder bowing with turning draw twisting procedure and utilizing distinctive material properties (types of material: 1.4301(2x40), 1.0036(2x40), 6060T7(2.5x40), 1.4301(4x40), 1.0038(4x40), 1.5415(7.1x51) and 1.7380(7.1x51)). The finite element method (FEM) and experimental tests are applied to compute the ovalization proportions.

Thus, development of solar panel cooling systems represents a new face of technology that may be used to improve power generation. Here, the reduction of solar panel temperature using an air-cooled heat sinks is studied numerically. The design of the heat sink comprises rectangular fins and rectangular fins with holes, made from a material with high thermal conductivity. The cooling efficiency is studied for different configurations of the heat sink, which are obtained by changing the fin numbers and hole distances. The numerical model is realized, using ANSYS-Fluent software, for a steady state whereby the ambient temperature is 25-35 °C, for different heat flux values. Increasing the number of fins and holes decreases the panel temperature. The reduction of panel temperature with fins is 50% compared to solar panels without fins. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

The regular operation of the PV system in an outdoor condition implies the need for a model that relate the environmental effects. This paper presents a new, simple, and efficient method for constructing the I-V characteristics for a PV cell incorporating the environmental conditions. The proposed model is based on the idea of dividing the voltage axis of the solar cell I-V characteristics using a fixed time interval. For each voltage interval point, a two-dimensional current matrix is calculated, corresponding different irradiance conditions and temperatures. Polynomial surface fitting is used to build sub-models for each voltage interval. The current two-dimensional matrix, for each point, is calculated by two different methods. The first method is based on linear interpolation of the measured I-V curves. The second method uses pre-extracted five parameters for the well known single diode model at a wide range of environmental conditions. The developed modelling technique provides accurate results compared with the measured data for a mono-crystalline solar cell. © 2020 Budapest University of Technology and Economics.

This paper considers the implicit form of the single diode model for solar cell to introduce and compare four new approaches for extracting the five characteristics parameters of PV cells/modules. Measured I-V curves for three different PV samples (mono-crystalline cell, polycrystalline module and amorphous module) under different irradiance conditions and temperatures were used to implement and validate each method. Numerical and optimisation methods were applied to solve different formulations of the single diode equivalent model. All methods are mathematically described, and the primary considerations when writing the MATLAB codes are highlighted. Comparison factors such as the mean absolute percentage error (MAPE), the algorithm convergence time (ACT), the coefficient of determination (R2) and the error at the maximum power point (δ), are used to evaluate each method. All proposed methods were verified, and the parameters were extracted with excellent performance. The method based on the least square fitting and solved by Newton–Raphson method provides the best results for the mono-crystalline sample compared to the other three methods while using particle swarm optimisation as a solving algorithm provides better results for the other two sample modules. The result of this work represents a guideline for extracting the five parameters of the single diode model from the measured solar cells/modules I-V curves. Although the SDM model does not describe the physical structure of the amorphous solar module, since this consists of a tandem p-i-n diode structure, the developed methods still deliver results with errors comparable to that of the single junction PV devices. © 2019 International Solar Energy Society | Elsevier Ltd | 0038092X | |

However, deposition of fine ceramic-reinforced MMC clads is challenging due to the divergence of fine particles. This leads to a non-uniform distribution of reinforcements and reduced clad performance. The high laser reflectivity of some metals such as Al also limits material deposition efficiency. In this work, the effect of a powder satelliting process on improving laser-deposited Al–TiC clads on aluminium 6082-T6 substrates was investigated. A simple-blended feedstock was also deposited for comparison. The effect of process parameters of laser energy and powder deposition density on clad characteristics of clad area, dilution and porosity were evaluated, and optimised parameters were identified. Two deposition mechanisms are proposed to explain the differences in the behaviour of both feedstocks within LC. The satellited clads yielded an increase of 29% and 113% in the deposition efficiency and TiC fraction, respectively, compared to the blended clads. The satellited clads yielded a mean increase of 60% in matrix microhardness and a mean reduction of 64% in specific wear rate compared with the blended clads indicating a clear improvement in the mechanical properties. © 2019 Elsevier B.V. | Elsevier B.V. | 2578972 | |

This paper reports on the design of a novel technique based, instead, on the domain of graphs. The dimensionality of each single EEG channel is reduced using a segmentation technique, and each EEG channel is then mapped onto an undirected weighted graph. A set of structural and topological graph characteristics is extracted and investigated, and several machine learning techniques are utilized to categorize the graph's attributes. The results demonstrate that the use of graphs improves the quality of epileptic seizure detection. The proposed method can identify EEG abnormities that are difficult to detect accurately using other transformation techniques, especially when dealing with EEG big data. © 2021.

Poly (maleic anhydride-co-methyl oleate) was prepared via the free radical polymerization of maleic anhydride with methyl oleate. The prepared copolymer was Characterized via FTIR and GPC and thermal analyses (TGA and DTA). TGA demonstrated that the prepared copolymer was thermally stable up to 146 °C. Electrochemical measurement tests, including potentiodynamic polarization tests, revealed that the prepared copolymer was successfully applied as an organic corrosion inhibitor for C-steel in 0.1 M HCl solution at 298 K, 308 K, 318 K and 328 K. Potentiodynamic polarization measurements revealed that this copolymer was a mixed-type corrosion inhibitor. Its inhibition efficiency was measured on the basis of potentiodynamic polariaztion curves via the electrochemical technique. Results demonstrated that the corrosion inhibition efficiency of poly(maleic anhydride-co-methyl oleate) increased with concentration and decreased with increasing temperature. Inhibition efficiency reached 94.8% with 20 ppm poly (maleic anhydride-co-methyl oleate) at 298 K. The adsorption of this copolymer on the C-steel surface was chemical adsorption and obeyed the Langmuir adsorption isotherm. © 2020 The Authors. Published by ESG (www.electrochemsci.org).

The study used the daily closing prices of six banks from Iraq Stock Exchange (ISE) over the period 1st Jan 2015 to 31 Dec 2017. The paper employed both symmetric and asymmetric models of different properties of "the Generalized Autoregressive Conditional Heteroscedastic (GARCH)". Findings obtained by the study could not give proof of the presence of a positive risk premium in the marketplace. Furthermore, the asymmetric model of the Exponential Generalized Autoregressive Conditional Heteroscedastic (EGARCH) showed asymmetry in stock returns which refers to the occurrence of power impact in the takings sequences. However, the results indicated that the good news is more destabilizing than bad news in ISE. © 2020, Periodicals of Engineering and Natural Sciences.

A total of 485 interviewees were randomly selected and data was obtained by a questionnaire-based survey. The questions were about awareness of zoonosis, health management, the transmission of diseases by different domestic animal species and consumption of their products, awareness of animals pet management, the transmission of diseases by wild-animal diseases, the impact of natural disaster on zoonosis, and extension of government or private-sector zoonosis work. The results showed that meat (43.92 percent) is the main way of transmitting zoonotic disease, with egg (18.14 percent) and milk (13.61 percent), depending on the levels of awareness of the different interviewers. There was more or less a similar concern about pet animal care (23, 71%) and wildlife zoonotic disease (26, 69%). It was noted that 33.81 percent of respondents were aware of the zoonotic infection caused by natural disasters. The participants also suggested that the government or the private sector offered extension services on zoonotic infection were 34, 22 percent. Among all the respondents, animal departure workers and teachers were very aware of the zoonotic infection. Zoonosis awareness in livestock keepers was high, followed by the health workers, teachers, and others. The present research found that practitioners or non-health trainees are not aware of zoonotic diseases with low education history. Further research needs to be undertaken to test zoonotic prevention and control approaches in the field of study. © 2020, Advanced Scientific Research.

Routine detection of V. cholerae infection can be achieved by isolation of the organism from stool sample on the selective medium, followed by biochemical tests and specific antibodies for serotyping and serogrouping. These methods are laborworking and time-consuming. Furthermore, they provide low sensitivity and specificity. Advanced diagnostic approaches for identification of V. cholerae, such as cell-counting techniques by immunoassay, PCR, and real-time PCR are also used. In addition to these strategies, nanotechnology including gold (Au) or silver nanoparticles and carbon nanotubes (CNTs) hold great promise for rapid, accurate, and cost-effective detection of pathogens. In recent years, composites based on golden-graphene nanoparticles have been synthesized using electrochemical methods. They are capable of detecting very low copy numbers of DNA from Vibrio spp. owing to the synergistic effect between the graphene and gold nanoparticles. Therefore, development of nanobiosensors using the gold nanoparticles combined the golden-graphene binary platform nanobiosensor that will open new avenues for the efficient V. cholerae identification.

Injection at a 4% and 8% flow rate is applied and investigated as a mitigation method for pressureinduced fluctuations along the draft tube. Contours of velocity and vorticity in the draft tube are presented to examine the effects of water injection. Probes placed alongside the draft tube measure the pressure signal and compare both operational regimes to characterize the pressure fluctuations. The intensity of pressure fluctuations along the draft tube wall is an order of magnitude smaller compared to that at the center. As the injection is applied, the intensity of the pressure fluctuations along the draft tube wall is increased while the intensity of pressure fluctuations in the center of the draft tube is reduced. Pressure probes in the center of the draft tube measure an 86% to 57% reduction in amplitude for 4% to 8% flow rate injection, respectively. There is a 30% to 40% increase in fluctuations along the wall for 4% to 8% flow rate injection, respectively. These changes in flow structure are due to the dissipation of the vortex rope as the injection is applied. © 2020 ASME. | American Society of Mechanical Engineers (ASME) | | |

The unit operated at 50% and 40% of the best efficiency design flowrate. Contours of vorticity, velocity, pressure, and iso-surfaces of Q-Criterion were presented to characterize the effects on the draft tube. Probes placed alongside the draft tube measure the pressure signal to investigate the flow-induced pressure fluctuations inside the turbine unit. The maximum intensity of pressure fluctuations at 50% partial load was 22.66% of the turbine head, while the strength of the pressure fluctuations was 26.36% at 40% partial load. A large number of unorganized smaller vortices observed in the draft tube contribute to the creation of pressure fluctuations. Two pressure modes can be easily recognized (1) high frequency with low amplitude pressure fluctuations and (2) low frequency with high amplitude fluctuations. These pressure fluctuations could be harmful to the structural integrity of the unit and also have undesirable influences on the operational stability of the hydro-turbines. © 2020 ASME. | American Society of Mechanical Engineers (ASME) | | |

On the other hand, the embryo can be defined as an evolving offspring over the first eight weeks post-conception; after that, it can be called a fetus till childbirth. The popular signs and symptoms of pregnancy might involve each of the missed period, inflated breasts, nausea with or without vomiting, repeated urination, and tiredness. A pregnancy test can be utilized for confirmation. The current study aimed to discuss the maternal medical outcomes after both: Caesarean section and natural vaginal childbirth. Results have shown that when the cases with cesarean and the normal delivery was compared in term of the adverse effects and the complications we find that there are no significant differences in term of normal blood loss while when the bleeding during and after delivery was investigated, we found the rate of it was significantly more in cesarean than in normal delivery, also fever was significantly higher in females who delivered in cesarean than who delivered with normal vaginal delivery. In conclusion, the incidence rate of cesarean section deliveries was increased compared to normal vaginal deliveries, so the complications and adverse effects that may be associated with the cesarean section need to be investigated and compared to what happens with normal vaginal delivery. © 2020, International Journal of Drug Delivery Technology.

This article then, investigates the position of paralinguistic factors: pace of delivery, pitch, intensity and pause pattern in King Martin Luther’s speech “Have a Dream” in political context. These factors carry attitude, psychological condition and emotional state of the speaker to the audience and affect their attitudes and emotions. These factors have been called the factors of delivery style because they can be used only in spoken language. These factors are the physical properties of speech and thus they are observable. These factors, thenwill be analyzed and studied with the help of van Dijk Model of CDA to answer To what extent the ideology of Martin Luther King Jr is reflected through the paralinguistic choices “I Have Dream”. In terms of the findings, the analysis found that persuasion is not the result of the use of the persuasive strategies in words and syntax alone as delivery style also plays an important role in persuasion. Pace of delivery along with pitch intensity and pause pattern are the main components of political speech delivery style for persuasive end. Moreover, the delivery style adds certain effect to other rhetorical strategies. Martin Luther King Jr. is a master of speech delivery style as he makes the best persuasive use of pace, pause, pitch and intensity in his speech. © 2020 All Rights Reserved | Anadolu Universitesi | 13085581 | |

We present a case of a patient with acute coronary syndrome admitted for percutaneous coronary intervention to the left anterior descending artery. The straightforward procedure was challenged by multiple complications of coronary artery perforation, cardiac tamponade, stent loss, and ventricular fibrillation. The management was complicated by covered stent embolization into the left circumflex artery without a wire inside. We were able to retrieve the lost covered stent by re-accessing the lumen with a coronary guidewire followed by advancing a balloon distal to the stent and extraction of the whole system outside. The case illustrates the possibility of facing multiple complications in one procedure including the loss of covered stent and how to prevent and manage this serious complication. © 2020 SOLEN s.r.o..

The turnover of FA proteins plays a critical regulatory role in cancer cell migration. Plasma membrane lipids locally generated or broken down by different inositide kinases and phosphatase enzymes to activate and recruit proteins to specific regions in the plasma membrane. Presently, little attention has been given to the use of phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) and Phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) fluorescent biosensors in order to determine the spatiotemporal organisation of PtdIns(4,5)P2 and PtdIns(3,4,5)P3 within and around or during assembly and disassembly of FAs. In this study, specific biosensors were used to detect PtdIns(4,5)P2, PtdIns(3,4,5)P3, and FAs proteins conjugated to RFP/GFP in order to monitor changes of PtdIns(4,5)P2 and PtdIns(3,4,5)P3 levels within FAs. We demonstrated that the localisation of PtdIns(4,5)P2 and PtdIns(3,4,5)P3 were moderately correlated with that of FA proteins. Furthermore, we demonstrate that local levels of PtdIns(4,5) P2 increased within FA assembly and declined within FA disassembly. However, PtdIns(3,4,5)P3 levels remained constant within FAs assembly and disassembly. In conclusion, this study shows that PtdIns(4,5)P2 and PtdIns(3,4,5)P3 localised in FAs may be regulated differently during FA assembly and disassembly. © TÜBİTAK. | TUBITAK | 13000152 | |

The dermal lesion occurs due to an obligate intracellular Leishmania parasite, which transmits by the bite of the infected female sandfly. This study aims to identify Leishmania species in Thi-Qar province/ South of Iraq and detect IL-17 level in serum of infected patients with L. tropica. The study was conducted in three local locations, Al-Hussein Teaching, Al-Suq Al-Shyokh General, and Al-Shatrah General Hospitals in the province for the period from the beginning of November 2018 to the end of October 2019. After clinical diagnosis, eighty out of two hundred forty-seven samples were selected for molecular examination by nested-PCR technique, where the lesion edge was injected by normal saline and pulled again to obtain the parasite DNA. Also, a measure of the IL-17 concentration level in serum of the patients with ELISA. The findings of the electrophoresis of the kinetoplast minicircle DNA gene showed that 65 samples were positive for cutaneous leishmaniasis, and observed two species of Leishmania spp. in the study area, 46 (57.5%) samples were L. tropica at 750bp and 19 (23.75%) samples were L. major. Serum IL-17 concentration recorded a significant increase among patients infected with L. tropica at different infection stages than control samples. Generally, the Nested-PCR technique is an accurate method for diagnosing clinical samples and molecular determination of Leishmania parasites. L. tropica is the dominant specie that caused CL in Thi-Qar province, while L. major recorded a low incidence. © 2020 Tche Quimica Group. All rights reserved. | Tche Quimica Group | 18060374 | |

However, people tend to consider it a threat. This study is an evaluation work to the understanding of the risk management and safety culture of the construction sector in oil and gas industry in Iraq. A survey questionnaire was prepared, tested, distributed to a sample of engineers, from several engineering specialties, who are working on different levels in the mentioned sector. A high percent of the respondents are safety engineers, and some have a higher university degree, e.g. MS an Ph.D. The collected data then analyzed using different statistical approaches. The results show that there is a good understanding of the safety in general among engineers. However, risk management and planning tools are not understood effectively among the respondents. Moreover, having a higher degree or specializing in different majors have no impact on perceptional understanding of the safety and risk. This study is one of the first steps in studying the occupational safety in Iraq construction and oil and gas industries. Since Iraq is considered for rebuilding after different wars, international firms are in need to understand how safety is managed and to what level it is applied. From this perspective, this study is one of studies that help achieving the firms’ goal regarding safety. © 2020. All rights reserved. | International University of Sarajevo | 23034521 | |

The normalized correlation values that is obtained by computing the cases values between the people behavior extracted and covid-19 reported case also has values close to 1 million by the end of June 2020 provided in dataset. In this research work, with more time, we would like to continue from the results we have achieved by training the RNN with NLP based sentiment analysis model for more extended periods of time for predicting the behavior of people during Covid-19 pandemic with 76.71% of accuracy which is high as compared to the CNN, such as days or weeks, in order to see how results can improve. The advancement in this field created an urge in me to research more on the techniques and methodologies developed for covid-19 extraction. During the outbreak of an epidemic, it is of immense interest to monitor the effects of containment measures and forecast of outbreak including epidemic peak affecting the behavior of people. To confront the change in behavior, a simple RNN based NLP sentiment analysis model is used to simulate the number of affected patients of Coronavirus disease. Our initial problem formulation involved investigating the ideal conditions and preprocessing for working with a specific NLP task: predicting the behavior during the specific time of May 20 – June 20 in 2020 for all four traits of common people during the Covid-19 pandemic. © 2020.

To fully harvest the structural capacity of building under constrcution with reinforced slabs sections exposed to combined actions, it is necessary to leave behind the simplicity of treating the verification of structural adequacy for normal stresses separately from that of shear stresses and instead fully exploit the advantages of choosing more efficient stress distributions. By exploring the vast possibilities of other statically admissible systems using optimization routines for deformation damage reduced to 20% from 80% in the work, the longitudinal reinforcement near the neutral axis in reinforced concrete can be utilized much more efficiently. In addition, by adhering to the interdependency constraints between normal and shear stresses in reinforced concrete a much more precise picture of the actual service stress state can be determined for impulsive loading and deformation damage where the maximum deformation and impulsive loading on RC-slab were observed at strain 91s < t < 97s on RC-slab in the total simulation steps from Os to 398s. There is therefore a need for a one- step, automated design tool capable of addressing such verifications holistically which was performed in the simulation of this study using Matlab R2019b. In this paper the theoretical basis and a free to use open-source design tool is presented, allowing for easy access to highly optimized designs capable of observing the impulsive loading and deformation damage on reinforced concrete materials to their limits © 2020 | International University of Sarajevo | 23034521 | |

The breeding values (BV) of the MM genotype were higher than those of the MN for SLW and REA of the carcass which were 0.766 and 0.186 respectively, while it was higher for MN genotype(5.962) in HOT trait. Thus strengthening the selection trend on the basis of MM genotype to raise the average weight of carcasses. Also, the dominant variation within the genetic variance was higher than the additive variance, reaching 10.598 and 0.599 for SLW and REA traits respectively indicating the strength of the initial reaction and its effect on the average characteristics. The average of the allele effect and the effect of substitution of alleles were all in favor of the M alleles compare to mutant allele (N), which encourages the selection against the mutant allele. © 2020 2020 © The Authors.

The HTMs were prepared through a facile steps reaction from cheap starting material. These HTMs exhibit good solubility and charge-transport ability but it has big issue regarding temperature due to degrade the conductive polymer, in the same time using ZnO NW as ETM. The perovskite based on PANI-SWNTs achieved power conversion efficiency (PCE) of 5% under air conditions. For perovskite, we found that the solar cells synthesized based on vertical ZnO nanowire arrays by using perovskite organic materials of CH3NH3PbI3 as active absorber materials, Pani-SWNT enable better photovoltaic performance than using CuO as HTM theoretical study by using simulator SCAPS solar cells. These results show that using CuO instead of PANI-SWNTs-HTMs have great prospect to replace the Pani-SWCNTs which is the most widely used HTM to obtain high—stability devices with temperature. © 2020 © 2020 author name, licensee AIMS Press.

They endow and enrich these plays with secondary and even tertiary meanings. However, because of the double or triple-tiered meanings of puns, these stylistic devices are not easily amenable to translation. The rich cultural connotations behind puns and the distinctive features of the puns’ form, sound and meanings pose great challenges to translators. Accordingly, care should be taken in the interlingual/intercultural transference of puns to transfer the effect achieved by these devices on the source recipients to the target recipients. Any mistranslation of puns will leave bad consequences on the recipients’ comprehension of the play’s atmosphere and characterization. In light of this, this study aims at identifying the strategies adopted by six Arab translators when rendering sexual puns in Shakespeare’s Hamlet into Arabic and the effect of each strategy on maintaining the intended communicative effect of puns on the recipients. In the analysis of the translation of puns in the Arabic versions of the play, Delabastita’s (2004) model was considered as the main theoretical framework. The data for analysis were collated from the play and its translated versions in Arabic by identifying puns in the ST and their counterparts in the TTs. The findings of the study show that the pun-to-pun, pun-to-zero-pun and pun-to-non-pun strategies were adopted when rendering puns in Hamlet into Arabic to naturalize the play to the Arab recipients, although this was at the expense of preserving the intended functions and communicative effect of this important stylistic feature. © 2020 DSR Publishers/University of Jordan.

This requires an efficient type of cryptography. Due to small size requirement, elliptic curve becomes the most suitable for such purpose. Objective: The encryption operation, in turn, increases the power required to transmit data through the network. The aim of this work is to reduce such power. Methods: This work suggests three methods to reduce the needed power. The first method is based on spread spectrum technology, which reduces the total number of levels in the network. The second method deals with algorithm used to choose the sensing node, while the third method suggests a cost function related directly to the available energy. Results: Computer simulation tests show a reduction in the required energy by 40% when we ap-ply the first method, while the second and third methods together reduce the energy by 12% of the total value of the whole network. Conclusion: The energy required to transmit encrypted data can be reduced with the aid of routing algorithms. These algorithm increase the coverage radius of the node transmission. © 2020 Bentham Science Publishers. | Bentham Science Publishers | 22103279 | |

This study relied on the Nomadic People Optimizer (NPO) for the tri-objective design of a stand-alone hybrid energy system (HES). The NPO algorithm comprises five main operators; these are the initial meeting, the semicircular tents distribution, the families searching, the transition of leadership, and the periodic meeting of the normal leaders. A HES optimized the electricity supply of a residential complex with 30 houses in Thi-Qar, which is located in southern Iraq at latitude 31.060 and longitude 46.260. The objectives of this study are to minimize the total life cycle cost (LCCT), total dump energy ( {DE}{Total} ), and total CO{2} emissions for 25 years. The deployed algorithm was used to evaluate six different power source scenarios (PV/battery, wind turbine/battery, 20-split diesel generators, a single large diesel generator, and PV/wind turbine/diesel generator/battery) when diesel a generator covers a deficit of renewable energy sources (RESs) without charges to the batteries, and PV/wind turbine/diesel generator and battery when a diesel generator covers a deficit in the renewable energy sources (RESs) with charges to the batteries. The data used in this study, such as the wind speed, solar radiation, and temperature, were collected from weather forecasts in Thi-Qar every hour for a full year; the data load was collected from the Thi-Qar Electricity Distribution Directorate for the same housing complex and the same number of houses in an area equipped with electricity. Additionally, the prices of the system components, maintenance, and cost of fuel were collected from the Iraq market. From the obtained results, the PV/wind/large diesel generator/battery system when the diesel generator charges the batteries was found to be the most attractive scenario because it achieved a total life cycle cost (LCCT) of, cost of energy of 0.080495746, total dump energy (GWh)) of, and total emission T(kg) of 2.957 10. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | The performance of a pump-turbine under partial flow rates, 85%, 75%, and 65%, is studied using the LES model. The power signal, velocity, vorticity, and pressure field is presented over the blades and throughout the draft tube. Pressure fluctuations are probed at various locations over the wall of the draft tube. Examining the flow field in the blade region can provide further insights into the system performance. Flow-induced pressure fluctuations can disrupt system stability. For this turbine, a strong swirling region is observed around the draft tube walls, causing pressure fluctuations. The size and intensity of this region decrease with the flow rate. A vortex rope is present in all cases. At the design point, the strength is constant throughout the draft tube. However, at partial load, the rope is weakened along the draft tube. Between the region dominated by the vortex rope and the wall, there is a swirling shear layer, which moves closer to the wall as the flow rate decreases. Both the magnitude of pressure fluctuations at the wall and the pressure difference over the blade decrease with the flow rate. The decreased pressure differences over the blade represent less power produced, and the decline in fluctuation magnitude at the wall represents more system stability. For this turbine, there appears to be a trade-off between power and strength of pressure fluctuations. © 2020 American Society of Mechanical Engineers (ASME).

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | Computational fluid dynamics simulations are conducted to characterize the spatial and temporal characteristics of the flow field inside a Francis turbine operating in the excess load regime. A high-fidelity Large Eddy Simulation (LES) turbulence model is applied to investigate the flow-induced pressure fluctuations in the draft tube of a Francis Turbine. Probes placed alongside the wall and in the center of the draft tube measure the pressure signal in the draft tube, the pressure over the turbine blades, and the power generated to compare against previous studies featuring design point and partial load operating conditions. The excess load is seen during Francis turbines in order to satisfy a spike in the electrical demand. By characterizing the flow field during these conditions, we can find potential problems with running the turbine at excess load and inspire future studies regarding mitigation methods. Our studies found a robust low-pressure region on the edges of turbine blades, which could cause cavitation in the runner region, which would extend through the draft tube, and high magnitude of pressure fluctuations were observed in the center of the draft tube. © 2020 American Society of Mechanical Engineers (ASME).

Adding thallium to structures makes it emit at larger wavelengths. The nonlinear effect of the injected signal power is examined for three quaternary thallium structures: In0.85Tl0.15AsSb, In0.93Tl0.07AsSb and In0.97Tl0.03AsSb. The gain peak was increased by four times and the wavelength was shifted to longer one for the In0.97Tl0.03AsSb quantum dot (QD) structure. This quaternary QD structure extends the emission wavelength to more than 12 μm which is important in long-wavelength infrared applications. The nonlinear behavior of these QD structures is also addressed. It is shown that the structure In0.97Tl0.03AsSb has a deeper spectral hole burning which is adequate for nonlinear signal processing applications. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020. | De Gruyter Open Ltd | 1734911 | |

However, surface evaporation results in the loss of both water and heat. This study therefore theoretically investigates the effect on temperatures within an SGSP when its surface is covered with a layer of air encased in a nylon bag. An earlier SGSP model was slightly modified to add the air layer and to estimate the temperature distributions of the upper layer or the upper convective zone (UCZ) and the bottom layer or lower convective zone (LCZ). The results for a year-long period showed that adding the air cover increased the LCZ temperature to a maximum of 94°C in July, with a total average increase of about 9% over the uncovered pond. In the UCZ, temperatures showed an average increase of approximately 45%, reaching a maximum of 34°C. The temperature of the air layer was meanwhile found to be close to the ambient temperature and behaved identically. These findings invite future experimental and theoretical investigations into the use of air layers to prevent surface evaporation, thereby enhancing the efficiency of SGSPs as a source of clean energy. © 2020, Tech Science Press.

ABAQUS program has been used in this research. The load-deflection relationship, crack pattern, strain in the concrete at mid-span section of the beam and failure modes of all tested beams are studied. After validation of FEM model, parametric studies are presented to assess the effect of the compressive strength of concrete, thickness, and length of CFRP, and the presence of CFRP on stress in steel bars. From the current results, it can be obtained that the flexural capacity of RC beams strengthened with CFRP increased by 6.6% for beam strengthed by EBR and to 108.8% for beam strengthed by near surface mounted (NSM) compared to the reference beams. According to parametric studies, it is found that by increasing the compressive strength of concrete from 30 MPa to 70 MPa, the beam capacity increase by 25.6%, while increasing the length of CFRP from 600 mm to 900 mm leads to increase the beam capacity by 12.7%. Increasing thickness of CFRP sheet from 0.11 mm to 0.5 mm leads to an increase in the stiffness and the flexural capacity of the beam by 47.9%. Also, the results of this study approved that the strengthening of RC beams by CFRP laminates using the NSM technique is more efficient than externally bonded reinforcement (EBR) techniques and this is agreed with the experimental results. Finally, it can be concluded that the finite element model provides good accuracy compared to the experimental results and ACI-440 results. © 2020 Potificia Universidad Catolica de Chile.

The objective of this study was to synthesize, structure and highlight biological features of new species of metal-organic complexes [(MCl2)2L1] {M = Ni, Cu, L1 = N,N'-1,4Phenylenebis(methanylylidene)bis(ethane-1,2-diamine)} and [(NiCl2)2L2]. The Schiff base ligands were prepared in an excellent yeilds by adding terephthalaldehyde to 1,2-ethane-diamine or 1,4-butane-diamine. Three binuclear Schiff base metal complexes were synthesized in a simple one-pot reaction by reacting the corresponding metal chloride (NiCl2 and CuCl2) salts with the Schiff base ligands {L1 = N,N'-(1,4phenylenebis(methanylylidene)bis(1,2-diethylamine)) and L2 phenylenebis(methanylylidene)bis(butane-1,4-diamine))}. The obtained Schiff base metal complexes were = N,N'-(1,4analytically, characterized by a set of spectroscopic techniques such as FT-IR spectroscopy, 1H NMR spectra, and mass spectra. The structures characterization studies suggest that Schiff base ligands behave as N bidentate ligands for nickel and copper metal centers, which are known to act as Lewis acids. The biological activity of the Schiff base of nickel(II) and copper(II) complexes was tested by using the broth dilution method. The complexes showed antibacterial activity against all gram-negative and gram-positive bacteria (Enterobacter cloacae G-, Citrobacter G-, Pseudomonas G-, Klebsiella G-, Staphylococcus G+, and Streptococcus G+) that used in the trials. It is concluded that Schiff base metal complexes are a good candidate for the antibacterial drug because of its good activity against gram-negative and gram-positive strains demonstrated in the present study, as well as in other studies in the literature. © 2020 Tche Quimica Group.

In literature, many existing preservation techniques and models have been discussed and presented with their detailed comparison as preservation rate of digital data growth has increased. Many western countries have already upgraded their paper-based systems to the smart system for preservation of government records including Turkey. In methodology, we used python language for the implementation of smart system application with OAIS framework to preserve archived paper-based records, it also provides a roadmap for the new digital ecosystem. It offers a framework that can be used to identify roles and responsibilities within a bounded system. Major ministries of Iraq (i.e. finance, electricity, science and technology) are developing specific guidance for preserving digital artifacts and records. Records accession, normalization and transformation have also been performed on the records during the process of preservation to clean the records and format conversion. In results, we achieved good preservation of most of the records from 2015 to 2019, the goal is to preserve which most of the records it belongs to digital format. The distribution of records preservation for major ministries of Iraq government in term of paper based and digitally preserved records from year 2015 to 2019. The preservation of digital records was recorded very low in 2015 as much of the record archival were paper based in all major ministries of the government. However, year-by-year the smart system tends preserve the records in digital format from old paper-based format and till 2019 large amount of records are being converted to the digital format. To have such smart system can be very helpful for preserving the records of the government, and useful for understanding how records are being preserved and their functionality. © 2020 EManuscript Technologies.

By using the first-principles of the density functional theory (DFT) calculations at the B3LYP/ 6-31G, which implemented in the Gaussian 09 software, various properties, such as the geometrical structure, DOS, HOMO, LUMO infrared spectra, and energy gap of the ZGNR, were investigated with various sites and concentrations of the phosphorus (P). It was observed that the ZGNR could be converted from linear to fractal dimension by using phosphorus (P) impurities. Also, the fractal binary tree of the ZGNR and P-ZGNR structures is a highlight. The results demonstrated that the energy gap has different values, which located at this range from 0.51eV to 1.158 eV for pristine ZGNR and P-ZGNR structures. This range of energy gap is variable according to the use of GNRs in any apparatus. Then, the P-ZGNR has semiconductor behavior. Moreover, there are no imaginary wavenumbers on the evaluated vibrational spectrum confirms that the model corresponds to minimum energy. Then, these results make P-ZGNR can be utilized in various applications due to this structure became more stable and lower reactivity. © 2020 Tche Quimica Group.

Most women with PCOS suffer from menstrual irregularity, hirsutism, alopecia, acne, infertility, alongside several metabolic disorder such as insulin resistance, obesity, hypertension and hyperlipidemia. This study was designed to estimate kisspeptin ( metastin ) hormone, follicle-stimulating hormone (FSH), luteinizing hormone(LH) and testosterone levels in women with polycystic ovary syndrome (PCOS), in comparison with controls, and study the correlations between kisspeptin and PCOS-related reproductive hormones, and investigate the relation between probable influence of KISS1 gene polymorphisms and hormone levels in women suffering from PCOS Methods: The study comprised 100 PCOS women and 100 controls(healthy women), with age ranging from 17 to 40 years. Blood samples were collected between day 3 and day 5 of the menstrual cycle(follicular phase) in both groups, BMI and circulating levels of serum kisspeptin(metastin), LH, FSH and testosterone were estimated. DNA was extracted from whole blood, and genotyping of rs4889 polymorphism in KISS1 gene was carried out by allele-specific PCR. Results: The values of BMI, kisspeptin, testosterone LH and LH-FSH ratio were significantly higher in PCOS women than controls. Plasma kisspeptin levels were positively correlated with LH levels. There was no statistically significant difference between the groups in terms of FSH level. The SNP rs4889 C/G, a non-synonymous SNP, was investigated in women with PCOS. The genotype (CG) had a significantly higher frequency (P=0.004) in PCOS group with OR of (2.316)than that of the control group. This would reflect that the genotype(CG) is a risk factor for PCOS occurrence within the sample size. Concerning the allele frequency of rs4889, the allele (C) showed a significantly higher frequency (41.5%, P=0.0008) in the PCOS group than that of the control group (25.5%). Conclusion: Overall, kisspeptin levels are higher in the PCOS women, this may be because disorder in hypothalamic-pituitary-gonadal(HPG)axis activity, thereby causing an increased level of LH which lead to irregular menstrual cycles and hyperandrogenism in PCOS women. Also, the results of the study show that the KISS1 gene polymorphism may be a factor contributing to PCOS development by its effect on increasing the kisspeptin hormone in the blood. The association between the gene and the gene variation and PCOS need further validation in large-scaled and functional studies. © 2020, Advanced Scientific Research.

In addition, Ti6Al4V (Gr.23) plasma atomised 100 wt% spherical powder was used as the reference powder with a flowability of 28 s to facilitate the tensile property discussion. It was found that the powder flowability is the crucial parameter governing the tensile properties of fabricated specimens. It was shown that the decrease in powder flowability (36.5 s) resulted in increases in susceptibility to the formation of a lack of fusion defects with dropped tensile properties. The microstructure of the fabricated Ti6Al4V alloy features the formation of prior β grain boundaries and an alpha prime (α′) martensite. Furthermore, no intermetallic aluminide phase (Ti3Al) precipitations in grain boundaries were detected through energy-dispersive X-ray spectroscopy analysis. © 2020 Informa UK Limited, trading as Taylor & Francis Group. | Taylor and Francis Ltd. | 2374068X | |

The study applied on 100 men, who suffering from mild and moderate obesity, their weight 104±6.23 kg, BMI 34.26 ±3.67kg/m2, age 33.5±6.1. They were divided in to 5 groups: group 1 (18) men: they are not training, not having flaxseed; group 2(21) men: they are training, not having flaxseeds; group 3(16) men: they are training, taking flaxseeds; group 4(23) men: they are not training, taking flaxseeds; group 5 (22) men: they are training, taking flaxseeds. The first four groups are under diet controlwhile the last group werewithout diet control.All groups were compared with the control group (16) healthy men who are not training, not taking any supplementand not following any diet program.ALT,AST, total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were measured in all group membersbefore and after the study period. From the static analysis of study results, it was noticed that there was a decrease in level ofAST,ALT, cholesterol, TGand LDL in all five group,especially in group 3 and 5. Whereas HDL level more increased in group 3 and 5 in spite of its raising in the other 3 groups. One of the most important risks of obesity is elevated liver enzymes and lipids profile that cause problems and other diseases. The use of flaxseeds with cardio exercise led to a decrease in the level of liver enzymes as well as cholesterol, TG and LDL and elevated level of HDL. Therefore, we must payattention to weight gain, which mostly ends in obesity by arranging the number of meals in a day, andavoid eating fatty food as well as fast food. In addition, the increase in weight can be reduced by focusing on the contents of the daily diet followed,increase physical activity and using flaxseeds in diets to reduce excess weight and avoid the incidence of chronic diseases. © 2020, Connect Journal. | Connect Journal | 9725075 | |

The theoretical simulation shows the carrier temperature increasing straight forward with increasing the surface density of the donor and accepter which had not studied earlier as the best of our knowledge. It clears that, the surface carrier concentration of donor or acceptor atoms supplying more hot carriers for wetting layer (WL) which is leading an increasing the carrier temperature. In other word, the long life time of carriers from WL to Quantum Dot (QD) states is very high. Consequently, the collision of carriers and nonradiative relaxation are increasing the CH effect. Also, the majority of carrier is responsible on the increasing of electron or hole temperature, so the variation electron temperature in N-type is higher than hole in valence band, while the reverse is done with doping with P-type. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020. | De Gruyter Open Ltd | 1734911 | |

The purpose of research was to study the influencing of partial shading on the energy efficiency of photovoltaic installations in various connection options. As the title implies the article describes a study of the possibilities of increasing their energy efficiency when operating under different conditions. It is spoken in detail about replacement of "block connection" panels to the "in-line connection", in case of partial shading by the previous string. It is shown that substitution allows to obtain a significantly higher power - up to 8 times. It is examined that the horizontal arrangement of the panels instead of the vertical, under the same conditions, also allows up to 5 times the power of the partially shaded array in the case "in-line connection" and by 34% in the case of a "block connection". It is analyzed that parallel connection of partially shaded photovoltaic array with normally illuminated, requires voltage matching, for the selection of electrical energy at the point of maximum power, which makes it possible to obtain much more energy from the shaded array. It is experimentally shown that when using the "Intelligent maximum power selection device" that implements the voltage matching, it is possible to increase the array power up to 4 times with partial shading of 3 panels of 18. It should be noted that the choice of methods that allow receiving energy from shaded panels through individual matching converters does not permit significantly increasing the energy production of partially shaded array. It is experimentally shown that as a result of their use the array power does not increase by more than 2.5%. The results of research can be used in the design of new installations based on photovoltaic cells and the modernization of existing ones. © 2020 Institut za Istrazivanja.

It examines pulsed, laminar blood flow through the state of the right coronary artery in a heart patient. Data for these cases were taken from a catheter laboratory in the Thi - Qar cardiac center. The case for a man born in 1976 who has normal RCA. A non-Newtonian blood model characterized by the Carreau equation was used, and a 3D model was used with the governing equations analyzed using the specified volumetric method. The SIMPLE algorithm has been adopted to link pressure and speed during runoff. Geometric figures are drawn using Auto CAD software and combined with ANSYS FLUENT 18.2 code program. The results showed that the speed increased in areas with a smaller diameter. Non-Newtonian viscosity increases its effect near the center of stenosis. The total pressure is equal to diastolic pressure with little increase. In the normal right coronary artery, it is noticed a difference in wall shear stress (WSS) distributions along the artery. This is due to the tilted axial velocity profile. The results were compared with literature to find high agreement. © 2020 Zibeline International Publishing Sdn. Bhd..

The objectives of this study were (1) to determine the prevalence of GI parasites in buffaloes in the Marshland areas of southern Iraq, and (2) to evaluate the association of risk factors with the parasitic infections. Materials and Methods: A total of 166 water buffaloes from the Marshland in the north of Basra (n=75), and Thi-Qar (n=91) provinces from November 2016 to April 2017 were enrolled. Fecal samples were collected and examined for the presence of helminth eggs and protozoal oocysts using sedimentation-flotation and centrifugal flotation techniques. Results: The overall prevalence of infection in buffaloes was 82% (136/166), with the highest number of single parasite infection (64%), followed by those with double (29%) and triple (7%) parasite infections. The most frequently identified parasites were Fasciola spp. (23%, 39/166), Eimeria spp. (19%, 32/166), Toxocara vitulorum (13%, 21/166), Trichostrongylus spp. (12%, 20/166), and Oesophagostomum spp. (10%, 10/166). Moniezia spp. was the only identified cestode with a prevalence of (8%, 13/166). A significant association was reported between feeding type and parasitic infections with Eimeria spp., Trichostrongylus spp., Moniezia spp., Trichuris spp., and Ostertagia ostertagia. Conclusion: The prevalence of GI parasitic infection in buffaloes raised in the Marshlands is high, indicating a high intensity of natural infection. The findings of this study imply an urgent need for the implementation of efficient control measures against parasitic infections in the Marshlands. © 2020 Lifescience Global. | Lifescience Global | 1927520X | |

The other adverse effects of TOCP extended into CNS (cerebellum and spinal cord) which was characterized by the degeneration of myelin sheath of myelinated nerve fibers with lamellated bodies' formation, auto phagocytosis of degenerate myelin by oligo dendrocyte. Severe cases exhibited mitochondrial degeneration especially in the axoplasm of myelinated nerve fibers associated with calcification in the lamellated degenerated mitochondria with complete loss of neurons which lead to loss of function. These findings concluded that the histopathological results supported the clinical and biochemical findings, and the severity of nerve damage in a dose-dependent manner. © 2020 Advanced Scientific Research.

The paper proposes a mathematical model of Fast ReRoute with load balancing based on the principles of Traffic Engineering (TE) and differentiated traffic policing in communication networks. The basis of the model is the conditions for the implementation of multipath routing together with the modified conditions for flow conservation, which take into account the priority traffic policing on the network edge in case of its probable overload. On the one hand, such an overload is caused by the increase in the load. On the other hand, it is caused by the implementation of protection schemes for network elements and its bandwidth in the course of fast rerouting. The advantage of the proposed solution is also the formulation of the Traffic Engineering Fast ReRoute with support of Traffic Policing (TE-FRR-TP) as an optimization one. The given optimality criterion focuses firstly on minimizing the dynamically controlled upper bound of communication links utilization that meets the requirements of the TE concept. Secondly, it minimizes the intensity of flows that receive denial of service at the edge of the network weighted in relation to the priority of serving. Using the proposed model on a number of numerical examples, the research of the policing based Traffic Engineering Fast ReRoute processes has confirmed the adequacy and efficiency of routing solutions made on its basis, both in terms of ensuring their fault-tolerance and load balancing, and in relation to traffic policing based on priorities. © Springer Nature Switzerland AG 2020. | Springer | 18650929 | |

The present study was a case-controlled study conducted in Basrah, Iraq. Of the 152 participants who met the inclusion criteria, 100 patients used different types of GCs. Of these 100 patients, 57 patients (57%) were current GC users, and 43 patients (43%) were not currently using GCs (had not used GCs in the past 30 days). The control group was comprised of 52 men (34.21%), considered as healthy participants, although 7 men (13.65%) were biochemically diagnosed with hypogo-nadism. Current GC exposure significantly decreased the total and free testosterone levels, whereas previous GC exposure increased estradiol (E2) levels, with the 31 patients on oral dexamethasone (cumulative dose, 18.9 mg) exhibiting a 7.5-fold increased risk of being diagnosed with hypogonadism. For previous GC users, a significant increase in the E2 level was observed, whereas all other gonadal hormonal levels were within normal reference ranges, including the total and free testosterone levels. The total cumulative dose of equivalent GCs was 240 mg, which resulted in a decrease in total testosterone levels, and subsequent hypogonadism. Oral dexamethasone at a lower total cumulative dose resulted in hypogonadism. © 2020, Spandidos Publications. All rights reserved. | Spandidos Publications | 20499434 | |

The hyperbolic telegraph equation is one of them, where it describes the vibrations of structures (e.g., buildings, beams, and machines) and are the basis for fundamental equations of atomic physics. There are several analytical and numerical methods are used to solve the telegraph equation. An analytical solution considers framing the problem in a well-understood form and calculating the exact resolution. It also helps to understand the answers to the problem in terms of accuracy and convergence. These analytic methods have limitations with accuracy and convergence. Therefore, a novel analytic approximate method is proposed to deal with constraints in this paper. This method uses the Taylors' series in its derivation. The proposed method has used for solving the second-order, hyperbolic equation (Telegraph equation) with the initial condition. Three examples have presented to check the effectiveness, accuracy, and convergence of the method. The solutions of the proposed method also compared with those obtained by the Adomian decomposition method (ADM), and the Homotopy analysis method (HAM). The technique is easy to implement and produces accurate results. In particular, these results display that the proposed method is efficient and better than the other methods in terms of accuracy and convergence. © 2020 Tche Quimica Group.

Increasingly strict environmental protection regulations forced fuel producers to improve their existing technologies and consider alternative means of removing sulfur compounds from crude oil. This study focuses on the batch adsorption of crude oil using an activated carbon Impregnated with metal oxide as an adsorbent. Activated carbon was successfully synthesized from waste tire material parts, it was cut, clean, dry, subjected to heat using a muffle furnace where temperatures were different at a specific time and activated by acid. then treated with a specified amount of water, ethanol and zinc nitrate hexahydrate for loading different rations of zinc oxide which improved its surface properties that measured via BET analysis which revealed the surface area about (183, 3 m2g-1) for more efficient adsorptive desulfurization. The effects of (0.5%, 5%, 10%, 20%, and 30%) metal loading percentage, (30°C, 40°C, 50°C, 60°C and 70°C) adsorption temperature, and (2hours, 2.5hours, 3hours 3.5hours and 4hours) contact time on the desulfurization efficiency of crude oil were studied. The zinc oxide activated carbon Nano composite with an optimum loading ratio (metal oxide / AC) of 10% exhibits a high percentage of sulfur removal. Based on the present experimental work an optimum desulfurization conditions for adsorptive desulfurization using zinc oxide activated carbon Nano composite as an adsorbent was found to be 10% metal loading, 50°C adsorption temperature and 2.5hours mixing time which corresponds to a desulfurization efficiency of 83% and a decrease in the sulfur content from 1.600%wt to 0.271%wt. © 2020 Innovare Academics Sciences Pvt.

The test program includes testing ten mixtures of SLWCs with a target compressive strength of (35 – 40 MPa) and a target air density less than 1900 kg/m3 in addition, three mixtures of normal weight concrete (NWCs) of target compressive strength equal to 37.5 MPa were used for comparison purposes. For each mix of the fresh-status measurements, including slump, density, the air content and the temperature, a number were carried out. Furthermore, the mechanical performance for both SLWCs and NWCs under compressive, flexural and tensile stresses were conducted. The results show that structural lightweight concrete could be produced using recycled low-strength bricks as coarse aggregates with a reduction in dry density equal to 22%. Moreover, the reported results indicate that the compressive strength, splitting tensile strength, modulus of rupture and elastic modulus of elasticity of SLWCs were lower those for NWCs by about 5%, 14.5%, 16.5% and 17.4%, respectively. Finally, correlations between compressive behavior and flexural behavior; compressive behavior and tensile performance; flexural behavior and tensile performance for SLWCs are proposed in this study. © 2020 Trans Tech Publications Ltd, Switzerland. | Trans Tech Publications Ltd | 2555476 | |

Therefore, we obtain three generalized Bayesian shrinkage estimators (GBSEs). In this approach, we find the posterior risk function (PRF) of the generalized Bayesian shrinkage estimator (GBSE) with respect to each loss function. The constant formula of GBSE is computed by minimizing the PRF. In special cases, we derive two new GBSEs under the weighted loss function. Finally, we give our conclusion. © 2020 N. J.

The study shown that the thickness of the gold layer, the radius of the air holes and the radius of the liquid holes all have a significant effect on the sensitivity of the sensor, where a wavelength sensitivity of (10,500 nm/RIU) was achieved at certain simulation conditions. Under these chosen conditions, the relationship of resonance wavelength with the refractive index of the liquid was linear and this gives flexibility to extend the range of the refractive index of the analyte without changing the sensor design. Approaching or moving away of the holes from center in the proposed design has a fundamental role in determining the sensor characteristics. © 2020 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

The research aims to study suitability of the sediments of the sand dunes extending on one side of the international road between Nasiriya-Baghdad near the check point of Fadak as fine aggregate used for the purposes of roads construction. The results of the geotechnical evaluation of physical properties showed that the grain size analysis of the fine aggregate did not meet the requirements of the Iraqi specification and according to these results, the aggregate needs to modify. Based on liquid limits and plasticity indices and according to Iraqi specification the deposits are suitable for using as sub-grade course materials and to construct the shoulders of the road but not suitable for using as sub-base course materials. While the results of chemical tests indicate that incompatibility of the rates of organic matters and calcium carbonates with Iraqi specification. On the other hand, the chemical analysis of the sediments showed that the rates of the chlorides, sulfates, gypsum, total soluble salts and pH they were within acceptable limits of standard specifications. The mineral components of the soils were characterized by clay minerals (kaolinite and montmorillonite) and non-clay minerals (quartz, feldspar, and calcite). © 2020 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

Four sites have been selected along both sides of Euphrates river. The geotechnical properties were used to separate soils that may be classified as susceptible to liquefiable from those non liquefiable. The criteria which are used in this study included effect of plasticity, natural moisture content, clay content, and voids ratio on the liquefaction susceptibility of soil. This study shows that 91% of soil samples lie within cyclic mobility zone depending on plasticity chart while according to natural moisture content and clay content, 100% and 81% of soil samples were classified as non-liquefiable soils. © 2020 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

Fasting involves complete abstinence of oral intake throughout daytime. Patients who have hypothyroidism usually require levothyroxine (L-thyroxine) replacement, which is typically given on an empty stomach away from meals. Taking L-thyroxine replacement without feeding is challenging during the nighttime of Ramadan, in addition to being prohibited during daytime. Objectives: This study aimed to determine the best time of L-thyroxine intake during Ramadan. Methods: Fifty patients who were taking L-thyroxine treatment for primary hypothyroidism were involved in this prospective study for three months including the fasting and pre-fasting months. The patients were divided into three groups with different times of L-thyroxine intake. In the group one (pre-iftar), the patients were asked to take L-thyroxine at the time of iftar (the sunset meal) but to delay any oral intake for at least 30 minutes. In the group two (post-iftar), the patients were asked to take L-thyroxine two hours after iftar. The patients in the last group (pre-suhoor) were asked not to eat in the last two hours before suhoor (the predawn meal) and to take L-thyroxine tablet one hour prior to suhoor. Results: When thyroid stimulating hormone (TSH) levels were compared before and after Ramadan, there were no significant differences neither within each group nor among all the study groups. Moreover, the frequencies of the TSH control after Ramadan showed no significant differences within each of the study groups (P = 0.18, 0.75, 1.0 for pre-suhoor, pre-iftar, and post-iftar respectively). Similarly, comparison among the groups of the study showed no significant differences regardless of whether the patients had controlled or uncontrolled TSH prior to Ramadan (P = 0.75 and 0.67, respectively). In the patients with controlled TSH before Ramadan, 8 out of 10 (pre-suhoor), 8 out of 12 (pre-iftar), and 4 out of 6 (post-iftar) maintained their control after Ramadan. While in the patients with uncontrolled TSH before Ramadan, 7 out of 10 (pre-suhoor), 6 out of 8 (pre-iftar), and 2 out of 4 (post-iftar) achieved controlled TSH after Ramadan. Conclusions: No significant differences in TSH control were observed in patients taking L-thyroxine at pre-iftar, post-iftar, or pre-suhoor time in Ramadan.

It is highly connected with T2DM that is defined by hyperglycemia, insulin resistance (IR), and hepatic malfunctions. Our study was design to determine the predictors for NAFLD’ incidence in T2DM patients. Methods: We conducted study of 299 subjects that were classified into two groups, (110) Non-Diabetic subjects and (189) T2DM patients, then the T2DM patients divided into two groups: T2DM (99) and DM+pre-NAFLD (90) patients. We measured hyperglycemia tests, Total Cholesterol, Triglycerides (Tg), Low-Density Lipoprotein Cholesterol (LDL-C), High Density Lipoprotein Cholesterol (HDL-C), Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), AST/ALT ratio, and γ-Glulamyltransferase for all groups. We determined the Triglyceride Glucose index, Interleukin-6, Alkaline Phosphate (ALKP), and C Reactive Protein (CRP) levels as biomarkers for IR and NAFLD respectively. Results: Our data demonstrated that DM+pre-NAFLD patients exhibited a significant increased in TC, TG, and LDL-C, and dramatic decreased in HDL-C compared to DM patients and Non-DM subjects. - AST, ALT, AST/ALT ratio and GGT levels showed a significant elevation in DM+pre-NAFLD and DM patients compared to the Non DM subjects. The data showed that TyG Index, IL-6, CRP and ALPK levels were increased in DM+pre-NAFLD patients only. The data showed a positive correlation between dyslipidemia, and liver function tests with IR and NAFLD biomarkers in DM+pre-NAFLD patients only. Conclusions: In T2DM, dyslipidemia deters liver enzymes functions, promotes the IR and increases the fatty liver accumulation. Liver enzymes, TyG Index, IL-6, CRP and ALPK could be non-invasive biomarkers for NAFLD in T2DM patients. ©Advanced Scientific Research. All rights reserved | EManuscript Technologies | 9758453 | |

The most commonly used human probiotics are members of the Lactobacillus and Bifidobacterium species. Besides these bacteria, Saccharomyces boulardii, a yeast strain, is also widely used as a probiotic to treat a variety of conditions, including antibiotics-associated diarrhea and recurrent Clostridium difficile infection. A primary advantage of using Saccharomyces boulardii as a probiotic is that it can be used by patients undergoing antibiotic regimen due to its natural resistance to antibiotics. The genetic transfer of antibiotic resistance genes, a frequent event between pathogenic and gastrointestinal tract (GIT) bacteria, is not as frequent between yeast and bacteria. Furthermore, Saccharomyces boulardii is also tolerant to various local stresses such as the presence of gastrointestinal (GI) enzymes, bile salts, organic acids, etc. and can withstand considerable variations in pH and temperature while transiting through the human GIT. Saccharomyces boulardii is known as generally regarded as safe (GRAS)with probiotic activity against a wide range of pathogens. This yeast is often marketed in a lyophilized form,“ S. boulardii lyo”, complete sequence of the genome was performed, and a comparative analysis of the genome was performed. From clinical studies, the results of randomized controlled trials in patients repeatedly confirmed the significant positive effect in the treatment of acute and chronic diseases. © 2020, International Journal of Pharmaceutical Quality Assurance.

The product was characterized by FTIR and GPC. The thermal properties (TGA, DTA) indicated that the prepared compound was thermally stable up to 150°C. The corrosion inhibition efficiency of the new compound as a corrosion inhibitor was evaluated for carbon steel in 0.1 N HCl as a corrosive environment and the inhibitor concentration was (0, 5, 10, 15, 20 and 25 ppm). The inhibition efficiency was measured by using Tafel plot in electrochemical technique. The results indicated that the effectiveness of the bis(3-mercaptopropyl)thioterephthalate as an inhibitor increases with the concentration but this characteristic is inversely related to the temperature. The inhibition efficiency (%IE) reached 97.32% for the 25 ppm concentration at 298 K. Potentiodynamic polarization measurements revealed that the product is a corrosion inhibitor of anodic type. The results showed that the inhibition occurs through adsorption of the inhibitor molecules on the C-steel surface. The adsorption of (BTPTT) on C-steel surface obeys the Langmuir adsorption isotherm and involves a chemisorption mechanism. © 2020, Russian Association of Corrosion Engineers.

Some azomethine compounds are very interesting material because of rich liquid crystalline polymorphism. Liquid crystals were discovered in 1888 by Australian Botanist Friedrich Reinitzer. The liquid crystal state was between the traditional solid and liquid phases and this is the origin of the term “mesogenic state.” The aim of the present work is to synthesize three series of Schiff bases S1, S2, and S3 using the microwave; the synthesized Schiff base has a number of carbon atoms at the terminal alkoxy chain with liquid crystal properties. Methodology: The prepared compounds were characterized qualitatively by Fourier transform infrared,1H-NMR,13C-NMR, and CHN analysis. The liquid crystalline properties of L1-L11 were verified using differential scanning calorimetry and hot-stage polarizing microscope (polarizing optical microscope). Results: A series of Schiff base (S1-S3) have been synthesized from the reaction of different amines (o-phenyldiamine,3,3’-dimethylbiphenyl-4,4’-diamine,pyridine-2,6-diamine) with some substituted aldehydes. The1H-NMR spectra of the synthesized compounds (S1-S3) in the DMSO-d6 as a solvent exhibited a singlet peak at 8.75, 8.56, and 8.67 ppm, respectively. Conclusion: Three series of Schiff bases S1, S2, and S3 were prepared using the microwave; the synthesized Schiff base has a number of carbon atoms at the terminal alkaoxyl chain with liquid crystal properties. © 2019 JPR Solutions.

Material: The experiment involved the schoolchildren aged 11-12 (n=43). The schoolchildren had no contraindication to the physical education. Classes according to the author’s module of need-motivational teaching tasks were conducted with the secondary school students of the fifth form “A” (n=22, experimental class). Pupils of the fifth form “B” (n=21) took a traditional training program during the physical education lesson of the “Volleyball” section. The study was conducted for two months (October-December 2018). Each pupil used a fitness bracelet during the class monitoring the heart rate at a physical education lesson. Special testing was used in three blocks. The first block is the calculation of the number of correctly performed technical actions with the ball without a partner. The second block is the calculation of the technical actions in pairs through the net. The third block is an educational game. Statistical analysis of the data was performed using t-student test.. Results: A significant (p<0.01 and p<0.05) advantage of the secondary school students of the experimental class was revealed in comparison with another approach to teaching the technical elements of volleyball. A higher mastery level of the basic elements in volleyball was obtained according to the special set of tasks: receiving and passing the ball with two hands from above; receiving and passing the ball with two hands from below (in place, with various types of movements, with lightened and complicated conditions). Conclusions: It is proved that an increase of the theoretical needful-motivational teaching tasks during the physical education classes has a positive effect on the activation of motor activity of the schoolchildren. The synergetic relationship between theoretical and practical training allows to achieve personal, regulatory, communicative, cognitive and objective results. © Nagovitsyn R.S., Kudryavtsev M.D., Osipov A.Yu., Altuvaini A.H., Markov K.K., Doroshenko S.A., Kuzmin V.A., Savchuk A.N., Kamosa T.L., Plotnikovа I.

This is mentioned by the legislator as an exception, because the general rule is that the administration must achieve written editorial control with the employee through the formation of an investigative committee, and it has, as an exception, recourse to these. Since the administrative interrogation is considered an exception from the original, it is not permissible to expand it by imposing other disciplinary penalties that differ from those specified by the legislator exclusively. In the event that this happens, the administrative decision becomes defective in form and procedures, which makes it deserve nullity. The administrative interrogation differs from the interrogation carried out by the investigative committee in the administrative investigation. This is because the administrative interrogation is a stand-alone procedural method. The legislator has the choice, in certain cases, to oversee the administration between the investigation or the interrogation, provided that the results of the interrogation are represented by the employee's conviction of the charges attributed. The employee must be punished with specific penalties, namely, (striking, issuing a warning, or salary deduction). © 2020, Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

Two genetic loci covering two regions within the CTLA4 and PTPN22 genes were amplified by PCR. Next, a direct sequencing strategy was performed for the observed PCR amplicons to assess the pattern of genetic polymorphism in the screened specimens. Subsequently, the observed variants were localized according to their positions within the referring genomic DNA sequences. The results indicated a significant increase (P<0.05) in thyroxin(T4) and triiodothyronine (T3) hormones while no significant changes of thyroid stimulating hormone (TSH) compared with health group. In addation, Our results indicated the presence of only one single nucleotide polymorphism (SNP) in the CTLA4 gene that was only localized in only one investigated patient sample compared with the normal referring sequences. This novel SNP, A81G, was observed in one samples, while no other SNP was detected in other samples . However, no variation was detected in all investigated samples concerning the investigated PTPN22 gene. In conclusion, the present study detected a novel A81G SNP within the targeted CTLA4 gene which may be associated with the progression of hyperthyroidism. Further large-scale screening studied is highly recommended to provide a more comprehensive view of this crucial genetic locus in Iraqi populations. © 2020 EManuscript Technologies.

In the current research, the SST k-ω model and finite volume method were employed to augment heat transfer into the separation flow of TiO2 nanofluid in the annular space of two concentric cylinders. In the present investigation TiO2 nanoparticles of volume fractions, 0.5%-2% at Reynolds number range of 10000-40000, and contraction ratios from 1 to 2 were considered at constant heat flux boundary condition. Simulation results reveal that the highest enhancement in the heat transfer coefficient is corresponding to the annular pipe with a contraction ratio of 2 due to the generated re-circulation flow zone that begins after the separation point on the wall. Further, the surface heat transfer coefficient enhances with the increase of nanoparticles volume fraction and Reynolds number. The velocity distribution profile before and after the steps reveals that increasing the height of the step and Reynolds number, re-circulation regions also increases. Numerical results indicate that the highest pressure drop occurs at the Re = 40000 and contraction ratio of 2. © 2020 Society of Thermal Engineers of Serbia. | Serbian Society of Heat Transfer Engineers | 3549836 | |

The first developed imaging method (Method 1) was firstly investigated on a metallic plate. A network of nine piezoelectric wafer active sensors (PWAS) was instrumented on an aluminum plate to receive impact signals. Based on Method 1, we need at least three sensors, which can be used to determine two hyperbolic paths, to localize an impact point on a metalic plate with known group velocities of generated waves (known its material properties). The observed results indicate that Method 1 can be used successfully to localize the impact points on a metallic plate. These successful results motivated us to investigate Method 1 on a composite plate. A second experiment of impact localization was implemented on a composite plate. Two clusters of sensors (every cluster has three PWAS transducers) were instrumented on the composite specimen to receive the generated acoustic waves due to break pencil leads at different points. The received signals were anaylized using a wavelet transform to determine the time of flight. The group velocity profile of antisymmetric Lamb wave mode was determined analytically at certain frequency. Based on Method 1, two hyperbolic paths, which are generated by four sensors, can be used successfully to localize the impact points on a composite plate with known its material properties. The second developed imaging method (Method 2) was investigated on the same composite specimen with assumption of unknown its material properties (unknown group velocity profile of generated wave). Based on Method 2, we need six sensors distributed on two clusters to determine two straight line paths. The intersection point of these two lines represents the impact point. The results showed that Method 2 can successfully localize the impact points on a composite plate. © 2020 SPIE. | SPIE | 0277786X | |

However, the prioritisation process for patients with multiple chronic diseases (MCDs) over telemedicine is becoming increasingly complex due to diverse and big data generated from multiple disease conditions. To solve such a problem, massive datasets must be collected, and high velocity must be acquired, specifically in real-time processing. This process requires decision-making (DM) regarding the emergency degree of each chronic disease for every patient. Multi-criteria decision-making (MCDM) approaches (i.e. direct aggregation, distance measurement and compromise ranking) are the main solutions for dealing with this complex situation. However, each MCDM approach provides a unique rank from those of other methods. By far, the preferred DM approach that can provide an ideal rank better than other approaches has not been established. This study proposes an extension of the technique for reorganising opinion order to interval levels (TROOIL). Such an extension is called Hybrid DM and Voting Method (HDMVM) which is based on different DM approaches (i.e. direct aggregation, distance measurement and compromise ranking). HDMVM is used to prioritise big data of patients with MCDs in real-time through the remote health-monitoring procedure. In this paper, we propose a methodology that is based on three sequential stages. The first stage illustrates how the big data of patients with MCDs can be recognised in the telemedicine environment and identifies the target telemedicine tier in this study. The second stage describes the steps of the proposed HDMVM sequentially. The third stage applies the proposed method by prioritising the case study of big data of patients with MCDs based on the above DM approaches. Moreover, dataset of remote patients with MCDs ( n = 500 ) is adopted, which contains three diseases, namely, chronic heart diseases and high and low blood pressures. The prioritisation results vary among direct aggregation, distance measurement and compromise approaches. The proposed HDMVM effectively provides a uniform and final ranking result for big data of patients with MCDs. A statistical method (i.e. mean) is performed to objectively validate the ranking results. Significant differences between the scores of the groups are identified in the objective validation, signifying identical ranking results. The evaluation of the proposed work with the benchmark study indicates that this study has tackled issues relevant to big data and diversity of MCDM approaches in the prioritisation of patients with MCDs. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Solving large-scale NLPs are usually so computationally expensive for resource-constrained users within a feasible time. The cost-effective solution is computation outsourcing, but this raises security concerns such as the input and output privacy of the customers, and cheating behaviors of the cloud since NLP problems always carry sensitive information. In this paper, we develop a practical secure and verifiable schema for solving outsourcing large-scale (NLP) with the GRG method. Also, we apply approximate KKT conditions for verifying the optimality of the result returned by the GRG algorithm.

The management of these polyps is complex since they can carry malignant lesions. Our study had aimed to analyze the results of ultrasound and pathological findings of patients operated upon due to polyps in the gallbladder. The study includes patients with ultrasound diagnosis of gallbladder polyps who underwent cholecystectomy in 2017-2019 were reviewed, and demographic, sonographic and histopathological data were collected. Sixty-eight patients were involved in the study. The median age was 42 ± 7 years, and 63.2% of our patients were women. The average size of the ultrasound polyps was 6.8 ± 4 mm. Histopathology confirmed the presence of polyps in 95.6% of patients, with an average size and number of lesions of 7.5 ± 5.8 mm and 1.7 ± 1.2, respectively. Eight polyps were larger than 10 mm, and the individual polyps were significantly larger than the multiple ones (p = 0. 004). Three cases of adenoma were diagnosed (4.6%); one of them was cancer in situ. All were single and over 10 mm. We found an important correlation between determining the size of an ultrasound polyp and the pathological anatomy (r = 0.93; p = 0.002). The tumor size was an indication of the presence of adenoma (p = 0.009, (95% CI = 1,113-1,678). We have concluded that there is a clear correlation between the size of the gallbladder tumor on ultrasound and the size in the pathological report. Gallbladder adenoma is uncommon and it correlates with the size of the polyp. In this study, the size was the only indicator of the presence of adenoma. © Annals of Tropical Medicine & Public Health | Wolters Kluwer Medknow Publications | 17556783 | |

It can be performed through collar incision which may end with a bad cosmetic appearance for this type of wound in the neck. Recently, laparoscopic total thyroidectomy has become popular in experience laparoscopic hand surgeons. There are many early complications that may occur after laparoscopic total thyroidectomy due to a new technique in total removal of the thyroid gland to give excellent cosmetic results. In our study, we compared the incidence of early complications, which occur within early 30 postoperative days, between LTT (laparoscopic total thyroidectomy) and OTT (open total thyroidectomy). 122 patients who had total thyroidectomy operation for simple multinodular goiter, 58 patients underwent LTT, while 64 patients OTT in GIT center in Thi-Qar city. All the operations were done by the same surgeon for all patients. The study was done through 2 years, from 1/5/2017 till 30/4/2019, through breast approach and collar incision. The surgical outcome has recorded the complications that occur to the patients within 30 days post-operatively. Results: the main age of patients in LTT was 39.6 and in OTT was 48.2 (p= 004). The operating time in LTT was 125.4+ 4 minutes, while in OTT was 92.6+2 (p=0.03). There were no significant differences in hospital stay in both groups. Patients with OTT experienced more pain than the ETT group postoperatively as evaluated by a visual analog scale. Cosmetically group LTT was very satisfied with this procedure according to the questionnaire we used. The follow-up period was 30 days only. The early complications were no significant differences between 2 groups as the LTT done by experience laparoscopic hands. 2 cases (3.5%) only converted to open procedure. Conclusion: LTT procedure is a new technique used to give an excellent cosmetic result rather than used collar incision in the midline of the neck; there are no significant differences in all early complications that may occur in LTT and OTT.

Recently laparoscopic total thyroidectomy was become popular in experience laparoscopic hand surgeons. Among patients, we noticed many early complications that may occur after laparoscopic total thyroidectomy due to a new technique in total removal of thyroid gland to give an excellent cosmetic result. In our study we want to do comparative study for incidence of early complication (which occur within early 30 postoperative day) between LTT (laparoscopic total thyroidectomy) and OTT (open total thyroidectomy). The prospective study done to 122 patients who mad total thyroidectomy for simple multinodular goiter. 58 patients underwent LTT and 64 patients OTT in GIT center in Thi-Qar city which are done by the same surgeon for all patients. study done through 2 years 1/5/2017 till 30/4/2019 through breast approach and collar incision. Surgical outcome records the complications that occur to the patients within 30 days post-operatively. The main age of patients in LTT was 39.6 ± 6.4 and in OTT was 48.2±8 (p= 004). The operating time in LTT 125.4± 4 minutes while in OTT was 92.6± 2 (p=0.03). There were no significant differences in hospital stay in both groups. patients with OTT experienced more pain than ETT group postoperatively as evaluated by a visual analog scale. Cosmetically group LTT were very satisfied with this procedure according to the questionnaire we used. The fallow up period was 30 days only. most of early complications are no significant differences between 2 groups as the LTT done by experience laparoscopic hands. 2 cases (3.5%) only were convert to open procedure.

Although there is a rising incidence in the frequencies of BC, there were not enough studies conducted on the incidence’s frequencies over the Iraqi women in Thi-Qar provinces. It is well-known that incidence rates are informative. Analysis of tendencies would advantage in planning and organizing programs for control cancers incidence. Objective: The objective of the following study is to calculate the risk of BC using updated data from the cancer registries in the Iraqi health ministry and document its tendencies that released in different periods. Materials and Method: Data on incidence rates of BC were obtained from cancer registries of Iraq for the period between 2009 and 2015. Annual percent change in incidence and risk in terms of one in the number of women likely to develop cancer was estimated for both cancers’ types in five cities in Thi-Qar province. Results: The incidence of BC ages group (45-49), (50-54) and (60-64) were significantly increased, while the age group (15-19) were significantly decreased. On the other hand, the higher increase in the incidence of BC in 2015 was reported to be 84 and 29 cases in Al-Nassiriya and Al-Shatra cities, respectively. Conclusion: Al-Refaey region recorded a decline in the incidence of BC, which is contrary to the observation in other cities, which showed an increase in breast cancer.

As well as, most of applied theories or predicted formulas deduced analytically from previous studies were feasible only for a particular testing environment and do not match other field or laboratory datasets. However, the performance of such techniques depends largely on input parameters that really affect the target output and missing of any parameter can lead to inaccurate results and give a false indicator. In the current study, data were collected from previous related literature including parameters handling the behavior of stone column and governing its bearing capacity. They included some parameters that were not considered previously; the undrained cohesion of soil, angle of internal friction and modulus of elasticity of fill material, area replacement ratio, and length to diameter ratio. The new model was generated using Neural Network Toolbox in MATLAB, all the five key parameters were treated as input data while the bearing capacity as the output data wanted to be predicted. A single hidden layer of twenty artificial neurons has been adopted in the generation of the model. The results and the regression analysis showed a high potential of using neural artificial network method in predicting the ultimate bearing capacity of soil strengthened with stone column. Thus, the study contributes in producing a reliable outcome as an alternative to using findings of costly and time consuming field or experimental tests. © 2020, Research Trend.

It will focus on the interactional practice of asking questions in Arabic political interviews. The study seeks to find out the kind of actions associated with the practice of questioning and answering in this setting, and what it tells us about the institutional responsibilities of its participants. Such transcripts which are widely available online can be utilised as an authentic language material for political discourse studies. Results showed that there are unique functions and forms to the question and answering turns in this institutional setting of talk, political interview. These functions are affected by the institutional mandate of the interviewer and the interviewees. Such differences may be the result of the specific institutional responsibilities that are framing the conversation and how it contributes in clarifying the public opinion with confrontational questions, considering the interviewee position as the top government figure in the country, the Prime Minister. Question/answer sequencing has been identified as a matter of concern in political interviews. According to the researchers' knowledge and the literature reviewed, no systematic study has been undertaken in the context of an Arabic (Iraqi in particular) TV show discourse, with political concerns. Approaches on talk-in-interaction, institutional talk and its effect on conversation will be applied. A literature review for these approaches is described with a focus on the question/answer turns.

This theme is clearly reflected in Dante's The Divine Comedy (1308-1321), a long epic poem. Accordingly, this study deals with Toni Morrison's Desdemona (2011) in light of the confessions of Dante's suffering spirits' who are portrayed as characters in his Divine Comedy, shedding light in particular on the subject of individuals who have died and so are prevented in communicating to the living. Therefore, metaphorically converting the setting literarily to the afterlife gives an opportunity to specific individuals to reveal what they want to tell, and this is the best way for authors to communicate and give their viewpoints. Depending on this thread, the character of Desdemona is the victim in Shakespeare's Othello (1603). This heroine is unjustly accused of infidelity after too few days of marriage to Othello and killed without her truth being told. Morrison attempts to give a voice to this victim to tell what she wants to reveal but from the afterlife, a metaphorical world. The study is divided into several accounts, beginning with an introduction and a background illustrating and preparing the main important relevant points. Dante's The Divine Comedy is explained in a separate section according to the chosen theme. Then, Morrison's Desdemona is analysed in light of the intended purpose. Conclusions are presented to clarify the results. © 2020 Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

SB was subjected to two types of alkaline pretreatment to assess their effect on SB characteristic, inhibitor formation, and enzymatic hydrolysis sugar yield. Dilute sodium hydroxide (DSH) and dilute sodium bicarbonate (DSB) were used for SB pretreatment. The pretreatment was carried out in a conventional heating environment (120ºC) for 10 min before the enzymatic hydrolysis step. The results showed that the treated SB by DSB resulted in higher removal of lignin (28%) compared to DSH (25%). The TGA, XRD, and SEM analysis results revealed that both types of pretreatment have slight differences. The crystallinity index (CI) for DSH and DSB was 43.2% and 41.2%, respectively. Meanwhile, HPLC results illustrated that the only inhibitor present in the pretreatment liquor is acetic acid at 0.25 mg/ml for DBS pretreatment and 0.063 mg/ml for DSH pretreatment. 229 ± 12 mg/g of total reducing sugar was found using DSH pretreatment, which is slightly higher than that one was obtained by DSB pretreatment (219 ± 16 mg/g) after enzymatic hydrolysis step.

(CL) have been widely used in herbal medicines worldwide. It has been shown to possess prophylactic effects against oxidative stress. However, there is a paucity of information regarding the protective role of CL against oxidative stress in the absence of toxic agents. The aim of the study was to elucidate the antioxidative stress pharmacodynamics of CL. Eighteen 12-week-old Sprague-Dawley rats weighing about 300 ± 25 gm were divided equally into six groups. Four of the groups were supplemented with CL at 100 mg/kg b.w./day orally (P.O.) and labeled as 1st, 3rd, 5th, and 6th day groups. The PCx (positive control) group was given distilled water orally, and the NCx (negative control) group rats were provided with food and water ad libitum. Blood samples were collected, and rats were sacrificed on days 1, 3, 5, and 6 (2 h) posttreatment. The blood was used for oxidative stress enzyme analysis (SOD, GSH-Px, and MDA) and liver (ALT) and kidney (creatinine) function assay, and the liver was dissected for histology. The results revealed that CL exhibited an antioxidative stress effect in the liver and kidneys as indicated by the low levels of ALT and creatinine. In response to antioxidant enzymes, especially that of the 3rd-day treatment group, an increase in SOD and GSH-Px indirectly caused an alleviation of oxidative stress, leading to a much lower level of MDA. It was concluded that treatment with CL at 100 mg/kg b.w./per day for three consecutive days demonstrated the highest efficacy in abating oxidative stress in rats. © 2020 Mohammed A.

Also, these goods are high in quality and reliability, lowest in cost and also rapid in delivery and response. The production companies are working to develop their production lines so that they are more flexible to change and can produce multiple products on the same production line, with the possibility of development to cope with the changing needs of customers. The changes of the production line from the production of a product to another needs a setup time and this time may be greater than the production time, thus leading to delay in the delivery of demands, which affects the reputation of the company and leads to customer dissatisfaction. Therefore, setup time is considered to be an influential factor in the production process. The determining of product sequence that reduces setup time using traditional approaches needs a long time to take all the possibilities for the relay process, and then to choose the alternative that reduces setup time. This leads companies to use modern scientific and quantitative approaches of rational decision making, and not enough of the experience of the decision maker or the use of traditional approaches in the process of decision making. In this paper, we used Genetic algorithms (GA) in decision making, which is one of the modern quantitative approaches to find the global optimum solution. It has been used to determine the sequence of products and the least setup time for a given set of demands. The proposed approach was applied in the Ur Company/ wire winding factory. The results showed the efficiency of the proposed algorithm in decision making to determine the production sequence in this factory, where GA take into account the product which ended the previous demand, and which one will begin in the later demand. Therefore, will be making a strategic and comprehensive decision and not a local decision. © 2020 Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

We have used the finite elements method to solve the Navier–Stokes equation, and an increase in temperature and velocity was found from the increased voltage. The increments of heat flux causes in increase of temperature with EDL effect. In general, we can note that two points are accurate, first, in the EDL region the velocity is formed, and then the maximum value of velocity reaches on outside the EDL with flat shape distributions for all selected cases. Second, the effects of viscosity and applied zeta potentials cause this velocity distribution of electroosmotic flow. The main objective of the simulation is to study the effect of electric magnetic in microchannel towards fluid flow profiles. The results shows that increasing voltage cause increase in velocity. © 2020 Zibeline International Publishing Sdn. Bhd..

Automatic analysis of PCG provides useful clinical information about heart operations for early detection and diagnosis of heart disorders. In this paper we design an algorithm to detect and classify the heart sound (PCG) signal into normal and abnormal sounds by using fuzzy inference system (FIS). The algorithm consisted of four stages, they are: preprocessing stage, segmentation stage, feature extraction stage and finally classification stage. In the preprocessing stage, PCG signals were first down sampled, and filtered by adaptive wavelet-based sub-level tracking. Next, the filtered PCG signal was segmented using envelop based segmentation using Shannon energy. Thereafter, zero crossing rate and root mean square features were extracted from the Shannon envelop and were used as inputs to FIS. Proposed algorithm reached 100% accuracy, and it was showed that proposed algorithm is effective for detection of abnormal heart operations. © 2020, Institute of Advanced Scientific Research, Inc..

Smart city, as one of the IoT applications, includes several sub-applications, such as intelligent transportation system (ITS), smart car parking and smart grid. Focusing on traffic flow management and car parking systems because of their correlation, this paper aims to provide a framework solution to both systems using online detection and prediction based on fog computing. Online event detection plays a vital role in traffic flow management, as circumstances, such as social events and congestion resulting from accidents and roadworks, affect traffic flow and parking availability. We developed an online prediction model using an incremental decision tree and distributed the prediction process on fog nodes at each intersection traffic light responsible for a connecting road. It effectively reduces the load on the communication network, as the data is processed, and the decision is made locally, with low storage requirements. The spatially correlated fog nodes can communicate if necessary to take action for an emergency. The experiments were conducted using the Melbourne city open data. © 2020, Springer Nature Switzerland AG. | Springer | 3029743 | |

The research used a questionnaire to collect its data. The research sample was chosen from employees who work in Iraqi industrial companies, including administrators, accountants, engineers and technicians. The research reached a number of conclusions, the most important of which is that the value analysis technique is a product design activity. It includes manufacturing products whose functional performance meets the expectations of customers at the lowest cost. Moreover, the value analysis technique helps to identify, analyse functions and exclude functions that do not add value in order to reduce cost and increase value without affecting quality. It does so through the use of creative thinking to help managers to distinguish between activities that add value and those that do not add value. © Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

The bifurcations of these dynamics is fully determined by the increasing the optical feedback strength OFBS. Our results show that small OFBS leads to a selection of QDLED dynamics. Increasing of the t leads to increase both in region of the double period and the chaos. Otherwise, bias dominates the course of photons. Adding the grating mirror as a special technique stabilize the oscillation of a QDLED. It is worth mentioning that we did not get a perfect behavior except using this technique. Delayed feedback and turn-on dynamics are studied. Results show that there is no change QDLED dynamics because of controlling the bias current on the behavior of photons and the effect of delay forces the system to enter the state of chaos while the turn-on dynamics of the QDLED structure show damping of the relaxation oscillations and the increase of phase shift with increasing both of OFBS and delay time. Dependence the outset of chaos on the linewidth enhancement factor is examined. © 2020 L&H Scientific Publishing, LLC. | L and H Scientific Publishing, LLC | 21646457 | |

Processes must be carefully managed in order to promote the formation of favourable high-integrity 'builds'. In this study, for the first time, a satelliting process is used to prepare a WCM-Co (12 wt.% Co) composite. Melting trials were undertaken to evaluate the consolidation behaviour of single tracks within a single layer. Tracks with continuous and relatively uniform surface morphology were obtained. These features are essential for high-quality AM builds in order to encourage good bonding between subsequent tracks within a layer which may reduce porosity within a 3D deposition. This study elucidates the formation of track irregularities, melting modes, crack sensitivity, and balling as a function of laser scanning speed and provides guidelines for future production of WCM-Co by laser powder-bed fusion. 2019 by the authors. © 2019 by the authors. | MDPI AG | 19961944 | |

High current injection gives high carrier temperature and a punch in the curve appears at low current due to the ground state carrier contribution. Increasing carrier-heating time increased carrier temperature. It is shown the slow relaxation for both the wetting layer to QD and the interdot relaxations are given high carrier temperature. Pulses with wide full width at half-maximum give high carrier temperature since its recovery time is increased. Free carrier absorption gives a main contribution to the heat in the QD structure. © 2020 Wiley Periodicals, Inc. | John Wiley and Sons Inc. | 8952477 | |

This research focuses on articles related to the keywords 'biometrics', 'finger veins' and 'verification' and their variations in three major databases, namely, Web of Science, ScienceDirect and IEEE Xplore. The final set of collected articles related to FV biometric authentication systems is divided into software- and hardware-based systems. In the first category, software development attempts are described. The experiment results, frameworks, algorithms and methods that perform satisfactorily are presented. Moreover, the experiences obtained from conducting these studies are discussed. In the second category, hardware development attempts are described. The final articles are discussed from three aspects, namely, (1) number of publications, (2) problem type, proposed solutions, best results and evaluation methods in the included studies and (3) available databases containing different scientific work collected from volunteers, such as staff and students. The basic characteristics of this emerging field are identified from the following aspects: motivations of using FV biometric technology in authentication systems, open challenges that impede the technology's utility, authors' recommendations and future research prospects. A new solution is proposed to address several issues, such as leakage of biometrics that leads to serious risks due to the use of stolen FV templates and various spoofing and brute-force attacks in decentralised network architectures in medical systems, including access points and various database nodes without a central point. This work contributes to literature by providing a detailed review of feasible alternatives and research gaps, thereby enabling researchers and developers to develop FV biometric authentication medical systems further. Insights into the importance of such a technology and its integration into different medical applications and fields are also provided. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Although, the acceptance of herbal medicines is growing nowadays still there is an absence of knowledge about their toxicological properties and the right use being a hepatotoxic.This paper presents method to detect and diagnoses liver lesions in four types: necrotic cells, fatty degenerative cells, hepatocellular hypertrophic cells and congested cells using image processing techniques. The method is proposed to perform two tasks the first is conclude whether the liver image is normal or abnormal the second if abnormal state is detected then diagnosis lesions type must performs. The method progresses in many steps are preprocessing, features extraction, classification and lesion diagnosing. Grey level co-occurrence Matrix (GLCM) technique is utilize to concentrate features to distinguish between normal and abnormal case using neural network classifier if abnormal state is detected the method feedback with colour image to analyse cells shape and image intensity colour to determine which type of diseases founded in image based on statistical and morphological features of cells. The method tested on 107 images it is got on the accuracy 100% in classification and 95% in diagnosing. Copyright © 2020 Institute of Advanced Engineering and Science.

It applied wavelet-Fourier analysis (WFA) to extract the statistical characteristics from an anaesthetic electroencephalogram (EEG) signal and to design a new DoA index. In this proposed method, firstly, the wavelet transform was applied to a denoised EEG signal, and a fast Fourier transform was then applied to the wavelet detail coefficient D3. Ten statistical features were extracted and analysed, and from these, five features were selected for designing a new index for the DoA assessment. Finally, a new DoA (WFADoA) was developed and compared with the most popular bispectral index (BIS) monitor. The results from the testing set showed that there were very high correlations between the WFADoA and the BIS index during the awake, light and deep anaesthetic stages. In the case of poor signal quality, the BIS index and the WFADoA were also tested, and the obtained results demonstrated that the WFADoA could indicate the DoA values, while the BIS failed to show valid outputs for those situations. © The Institution of Engineering and Technology 2019. | Institution of Engineering and Technology | 17518822 | |

Due to their ability to fill even in extremely small voids and their pozzolanic reactivity, silica nanoparticles were found to effectively modify concrete microstructure into refined denser system. They considerably improve the cement-aggregate Interfacial transitional zone by filling the voids, consuming CH crystalline particle and producing more CSH gel. These modifications are presented as SEM images, XRD and thermogravimetric TG graphs as reported by the researchers. Through the microstructure improvement, NS was found to enhance most of concrete mechanical and durability properties.

There are many ways in which the digital elevation model can be obtained, such as the Field Survey and the use of Global Positioning System data, topographic maps and other methods. In this research, a Digital Elevation Model (DEM) has been built dependent on three methods (positioning system—ground survey—topographic maps) in addition to the use of GIS technology to produce high-resolution 3D maps (2 mm) was chosen for application to the city of Nasiriyah, the center of Dhi Qar governorate in the southern Iraq to show the Hydrological hazards on the studied area and the methods of protecting it. It was found that there are many hydrological hazards to the city especially in the winter season such as the erosion of the soil by rain which reached 12.977 tons/ha and the water immersion whose ratio reached to 0.34 cm in some areas. In addition, the study showed that the area is exposed to the danger of flooding in percentages ranging from 0 to 90%, covering 50–60% of the risk of most parts of the study area. Finally, it was concluded that the rise of groundwater levels (0.73 cm) affects on buildings, foundations, soil and infrastructure. © Springer Nature Switzerland AG 2020. | Springer | 23662557 | |

The model of surface dimensions is constructed on the basis of the calculated values of the processing surface radii in order to estimate the errors of a diametrical size and shape error and location of the surfaces with a simultaneous evaluation of circular grinding cycle productivity. The model of metal removal for the circular external grinding cycle, described in this article, can be used not only for prediction of the processing accuracy for a given processing cycle, but also for designing a speed-optimal cycle, i.e., the model is a basis for development of an optimal cycle creation methodology. © 2020, Springer Nature Switzerland AG. | Springer | 21954356 | |

As a result, CNC machines are used inefficiently; full automation of the preparation of control programs for CNC machines becomes impossible without using high-performance optimum grinding cycles ensuring stable processing accuracy; it is also impossible to design manufacturing cyber-physical systems in accordance with the concept of “Industry 4.0.” The article describes the synthesis of the digital twin technology and dynamic programming method for designing the optimal grinding cycle for resistance to variable technological factors, which makes it possible to: prevent the rejection of circular grinding; determine the causes of rejection; improve reliability and stability of the grinding cycle to the cumulative effect of variable factors; predict the fluctuation of accuracy and roughness parameters, hardness of the machined surface when processing a batch of parts. The practical result of the synthesis of the digital twin technology and dynamic programming method is an increase in the level of designing automation of control programs for CNC machines, ensuring the calculation of optimal values of radial feed at all cycle stages, the optimal distribution of the allowance removal over the cycle stages, which ensures the minimum main grinding cycle time and reduction in risks to meet the specified requirements on the quality of the machined surface of the part. © 2020, Springer Nature Switzerland AG. | Springer | 21954356 | |

An example application is to aid the regeneration process of peripheral nerve injuries. Herein, we present a promising approach for three-dimensional (3D) micropatterning of nerve cells in tissue scaffolds for peripheral nerve repair. In particular, we demonstrate the 3D micropatterning of PC12 cells in a gelatin-hydroxyphenylpropionic acid (Gtn-HPA) hydrogel using ultrasound standing waves (USWs). PC12 cells were first aligned in 3D along nodal planes by the USWs in Gtn-HPA hydrogel precursor solution. The precursor was then crosslinked using horseradish peroxidase (HRP) and diluted hydrogen peroxide (H2O2), thus immobilising the aligned cells within 90-120 s. This micropatterning process is cost effective and can be replicated easily without the need for complex and expensive specialised equipment. USW-aligned PC12 cells showed no adverse effect in terms of viability or ability to proliferate. To our best knowledge, this is the first report on the effect of USW alignment on neural cell differentiation. Differentiated and USW-aligned PC12 cells showed directional uniformity after 20 d, making this technique a promising alternative approach to guide the nerve regeneration process. © 2019 IOP Publishing Ltd. | Institute of Physics Publishing | 17585082 | |

Nitrogen fixation by life organism Rhizobium spp. is an important to increase growth and yield. The study aimed to determine the distribution and activity of bacteria symbiotic in legume growing at Thi-Qar province-southern Iraq. Field survey studied at six locations grew with legumes to know bacteria types. Two field experiments were studied, so the first was the effect of bacteria concentration on cowpeas growth. Three bacterial concentrations were studied. The second was bacteria concentration and nitrogen fertilizer effectiveness on alfalfa dry and fresh weight yield including 3 levels from both factors. Plant vegetative qualities and nodules number affected significantly by the bacterial concentrations. The alfalfa dry and fresh yields significantly were affected by bacterial concentration and nitrogen. The inoculation of seed before planting is important to increase legume growth and yield. The biological Nitrogen fixation is the most important procedure in agriculture to reduce using of amount Nitrogen fertilizers to crop because of amounts of Nitrogen fertilizers is losing by many processes, like (soil erosion, ammonia volatilization, Denitrification, leaching NO3, and immobilization process).

Developing an efficient method for scoring electroencephalogram (EEG) sleep stages is expected to help medical specialists in the early diagnosis of sleep disorders. Method: In this paper, a novel technique is proposed for classifying sleep stages EEG signals using correlation graphs. First, each 30 s EEG segment is divided into a set of sub-segments. The dimensionality of each sub-segment is reduced by using a statistical model. Second, each EEG segment is transferred into a graph considering each sub-segment as a node in a graph, and a link between each pair of nodes is calculated based on their correlation coefficient. Graph's modularity is used as input features into an ensemble classifier. Results: Different community detection algorithm based correlation graph are investigated to discern the most effective features to reveal the differences between EEG sleep stages. A combination of various classification techniques: a least square vector machine (LS-SVM), k-means, Naïve Bayes, Fuzzy C-means, k-nearest, and logistic regression are tested using multi criteria decision making (MCDM) to design an ensemble classifier. Based on the results of the MCDM, the best four: LS-SVM, Naïve Bayes, logistic regression and k-nearest are integrated, to finally utilise as an ensemble classifier to categorise the graph's characteristics. The results obtained from the ensemble classifier are compared with those from the individual classifiers. The performance of the proposed method is compared with state of the art of sleep stages classification. The experimental results showed that the EEG sleep classification based on correlation graphs are able to achieve better recognition results than the existing state of the art techniques. © 2019 Elsevier Ltd | Elsevier Ltd | 9574174 | |

Specific types of antibiotics have been associated with side effect like diarrhea, this called (collateral damage), which may occur due to drug-resistant organisms and the unwanted development of colonization or infection with multidrug-resistant organisms. This damage is mostly related to levofloxacin and Ciprofloxacin. The aim of the current study was to compare the incidence of collateral damage between two quinolone antibiotic derivatives (ciprofloxacin and levofloxacin) and to evaluate the activity of lactobacillus to reduce the collateral damage. This study was carried out on 100 patients. Administration of ciprofloxacin, levofloxacin each alone or in combination with lactobacillus; the character of diarrhea and the grade of diarrhea was studied before and after 10 days of administration each dosing protocol. The results for this study, there are a significant increase in the incidence of diarrhea for all groups when comparison between before and after treatment diarrhea was made; a number of patients with diarrhea in group 1 after finish the treatment was not significantly higher when compared with group 2 (P>0.05); meanwhile, number of patients with diarrhea in group 4 after finish the treatment was significantly lower when compared with group 3 (P<0.05). it can concluded that , The use of ciprofloxacin and levofloxacin associated with incidence of collateral damage represented as diarrhea and levofloxacin is the least risk of this damage, and using of lactobacillus with levofloxacin was better results than the other three groups. © 2019 University of Baghdad - College of Pharmacy.

It is effective for acute migraine attacks, but has a short half life (about 2 hours) and low oral bioavailability (15%). The purpose of this study was to develop and optimize nasal mucoadhesive in-situ gel(IG) of ST to enhance nasal residence time for migraine management. Cold method was used to prepare different formulas of ST nasal IG, using thermosensitive polymers (poloxamer 407 alone or with poloxamer 188) with a mucoadhesive polymer hyaluronic acid (HA) which were examined for gelation temperature and gelation time, pH, drug content, gel strength, spreadability, mucoadhesive force determination, viscosity, in-vitro drug release, and the selected formula was subjected to fourier transform infrared (FTIR) compatibility studies, and to ex-vivo permeation study, histological evaluation of the sheep mucosal tissue after ST nasal gel application for 6 hours.The results showed that the formula IG7 prepared from poloxamer 407(19%), poloxamer188 (4%) and HA (0.5%) had an optimum gelation temperature (32.66±1.52°C), gel strength (43.66± 1.52 sec), mucoadhesive force (8067.93± 746.45dyne\cm2), in-vitro drug release (95.98%) over 6h, ex-vivo permeation study (89.6%) during the 6 h. study with no histological or pathological change in the nasal sheep tissue and no interaction between drug and other additives in IG7. Formulation of ST as a nasal insitu gel to avoid first pass metabolism and ease of administration coupled with less frequent and sustained drug release, will enhance patient compliance. © 2019 University of Baghdad - College of Pharmacy.

The propagation properties for the proposed O-PCF were studied numerically by utilizing full-vector finite element method (FV-FEM) using COMSOL Multiphysics version 5.1. The confinement loss, the relative sensitivity, and the nonlinearity coefficient can be controlled by changing the factors related with the geometry such as the cladding in a range of wavelength, air hole diameter, and the core pitch. The proposed O-PCF is realized with three rings from the air hole in the cladding and two circular rings in the core region. Numerical simulation of the proposed structure is achieving the highest sensitivity by increasing the diameter of the air hole the cladding, while the pitch remains constant. At the same time, the confinement losses have distinguishable decrease with an increase in diameter as well as an increase in the number of rings within the cladding layer. In addition, the effective area and the nonlinear coefficient each of them is affected with every hole of the diameter and with the type of the chemical material used. The proposed model shows that the fiber is of a high efficiency not only in the sensing application, but also being distinguishable with the nonlinear optical application. © 2019 Author(s). | American Institute of Physics Inc. | 0094243X | |

Our goal is to explore the complex dynamics (i.e. the oscillation phenomenon) of this architecture mediated by this interaction. This model was theoretically and numerically investigated using distributed time delay. We considered the average delay as a bifurcation parameter and the nonlinear degradation rate as a control parameter. Sufficient conditions for local stability were gained by using the Routh-Hurwitz criterion in the case of a weak delay kernel. Then we proved that Hopf bifurcation happened and the direction of the periodic solution was determined using multiple time scale technique. Our results suggest that the interaction among several identical mRNA plays the main role in gene regulation. © The Author(s) 2018.

The samples were collected from of three stations during the autumn and winter season. Heavy metals (Cd, Cu, Pb, Fe and Zn) were detected using an Atomic Absorption Spectrophotometer. The heavy metals concentrations in the water, plants and sediments were detected during the autumn and winter season. Ceratophyllum showed higher heavy metals concentration of Cd, Cu, Pb, Fe and Zn in station 3 than Phragmites during the autumn season. High amount of heavy metals (Fe, Cu and Zn) in sediment samples were also in station3 during winter season. However, Season and location play a significant role in the heavy metals content of water, plants and sediment. The Ceratophyllum had the highest heavy metals content while Phragmites had the lowest for both the seasons. © 2019 Ecological Society of India.

The aim of current study was to investigate the possible correlation between human cytomegalovirusand Epstein Barr virus with type 1 diabetes mellitus.Methods: A total of 56 patients diagnosed with Type-1-diabetes who attended the Special Center for Endocrine Glands and Diabetes in Al-Nassyrieh city, and another control group of 30 nondiabetic healthy people were selected. These two groups were of age range 3-22 years old and from both sexes. The sera from both groups were collected and divided into two parts. One part for the serological detection of IgM and IgG antibodies against human cytomegalovirusand Epstein Barr virus by the enzyme-linked immune sorbent assay (ELISA) and another part to detect the viral target genes of human cytomegalovirusand Epstein Barr virus genome by the conventional Polymerase Chain Reaction(PCR) technique.Results: The results revealed that only 2(3.60%) of Type-1-diabetes patients were positive for anti-human cytomegalovirus IgM antibodies compared with a negative result of the control group and 53(94.60%) of Type-1-diabetes patients were positive for anti-human cytomegalovirus IgG antibodies compared with a full percentage in the control group (100.00%). Also, ELISA results indicated the presence of anti-Epstein Barr virus IgM antibodies and anti- Epstein Barr virus IgG antibodies in 7(12.50%) and 24(42.90%) of Type-1-diabetes patients, respectively, compared with negative results for both anti- E[stein Barr virus IgM and IgG antibodies of the control group. Regarding PCR technique, the results revealed that (33.93%) of Type-1-diabetes patients had Human Cytomegalovirus DNA and (26.79%) of Type-1-diabetes patients hadEpstein Barr virus DNA compared with none of the controls had Human Cytomegalovirus DNA or EpsteinBarr virus DNA (P<0.001).Conclusion: According to these results, the current study concluded that Human Cytomegalovirus and EpsteinBarr virus infections may have a role in the pathogenesis, development and progression of type 1 diabetes mellitus. © Annals of Tropical Medicine & Public Health S267. | Wolters Kluwer Medknow Publications | 17556783 | |

Metformin has also been shown to decrease the growth of breast cancer cells and pancreatic cancer in hamsters and delays other types of tumors. The aim of this study was to compare the effects of Cisplatin (Cis) alone and Metformin alone on colon cancer cell line SW480. The results showed that the effect of Metformin on cell proliferation is concentration-dependent. Metformin enhances the proliferation and attachment of colon cancer at lower concentrations. Results showed a significant decrease in cell proliferation and attachment of colon cancer cells after Cisplatin treatment.Results of this study revealed that Cisplatin treatment decreased both proliferation and cell adhesion to the matrix. Combination therapy (Met+Cis) showed promising synergism and enhancement of anticancer activity of Cisplatin on colon cancer cells. We are strongly recommended more investigations to be more specific for using Metformin as general anticancer. © Annals of Tropical Medicine & Public Health | Wolters Kluwer Medknow Publications | 17556783 | |

An effective and safe vaccine remains a high priority. Most HIV vaccine candidates to date have failed to elicit effective immune responses that are necessary to control HIV infection. The results of a promising phase III trial conducted in Thailand using a recombinant canarypox vector vaccine (ALVAC) expressing HIV Gag in combination with recombinant HIV-Env glycoprotein gp120 (AIDSVAX), showed 31.2% efficacy in humans and raised the prospect of a protective vaccine. The most recommended HIV vaccines are focusing on inducing specific CD8+ T as a critical immune response to control progression and dissemination of HIV virus from the site of infection into different mucosal compartments of the body.This study project used influenza viruses as a mucosal live vaccine vector to stimulate effective CD8+ T cell immunity. Recombinant influenza A viruses, H3N2 (HK-X31) and H1N1 (A/PR8/8/34) expressing defined mouse HIV-1 CD8+ T cell epitopes (H-2Kd Gag197-205 and H-2Kd Tat17-25) in the neuraminidase (NA) stalk were generated using reverse genetics and administered as a prime-boost vaccine within various mucosal routes of vaccination, intranasal-intranasal, intravaginal-intravaginal, intranasal-intravaginal and intravaginal-intranasal vaccination in BALB/C mice. Following those prime-boost vaccinations, tetramer and intracellular cytokine staining assays used for the detection of specific CD8+ T cell immune response in harvested organs, spleen, bronchoalveolar lavage (BAL), mediastinal and inguinal lymph nodes. In addition, mucosal HIV-specific CD8+ T cells were detected using specific anti-mouse CD8α antibodies directed against specific integrins (LPAM-1 and CD103). Moreover, the level of specific cytokines, such as interleukin-15 (IL-15) detected within specific mucosal CD8+ T cells for the detection of the migrated HIV-1 Gag+ CD8+ T cells.Our result showed there was an induction of CD8+ T cells targeted H-2KdGag197-205, compared to no CD8+ T cell responses specific for H-2Kd Tat17-25 in recombined influenza-HIV vaccinated BALB/c mice. Also, comparable HIV and endogenous influenza-specific CD8+ T cell responses following intranasally-intranasally prime-boost vaccination in harvested lymphoid tissues, spleen, bronchoalveolar lavage, and mediastinal lymph nodes compared to inguinal lymph nodes which included a high proportion of specific CD8+ T cell immune response following intravaginal-intravaginal prime-boost infection. Moreover, a proportion of these cells isolated from mice infected with recombinant influenza-HIV vaccine intranasally-intranasally prime-boost expressed mucosal surface integrins, especially LPAM-1(α4β7) of local and distal lymph nodes higher than the levels observed following intravaginal vaccination. In addition, mucosal LPAM-1+HIV-Gag197-205+ CD8+ T cells harvested of intranasal prime-boost vaccinated mice were recognized by a high expression of IL-15 compared to LPAM-1-HIVGag197-205+ CD8+ T cells.We conclude that the intranasal prime-boost vaccination as one of the mucosal routes of vaccination using recombinant influenza viruses as mucosal viral vectors of HIV vaccine in BALB/c mice has an important role in stimulating both specific and mucosal CD8+ T cells within a high level and these cells would be important for migration of mucosal specific CD8+ T cells given the mucosal acquisition of HIV infection and control of HIV-1 virus dissemination through mucosal compartments. © Annals of Tropical Medicine & Public Health S234 | Wolters Kluwer Medknow Publications | 17556783 | |

The gonadotropins which are most frequently used during COS/ICSI cycles are r-FSH and r-HMG (FSH+LH). Over many years, outcomes achieved with using both gonadotropins during COS have been compared and the superiority of using both or only r-FSH is still a controversial topic that necessitates further studying. The aim of this research is to study the effectiveness of adding r-HMG to r-FSH on ICSI outcome in infertile patients who underwent COS. Fifty infertile couples were included who attended fertility clinic due to either female factor or male factor infertility and all of them were treated by ICSI and subjected to COS by r-FSH with or without r-HMG. ICSI outcome was assessed in the form of the total number of retrieved oocytes, FR, CR, embryo quality and chemical PR.The study showed that there was no significant difference between using both gonadotropins or FSH alone regarding the total number of oocytes produced, fertilization rate (FR), cleavage rate (CR), embryos number and quality except pregnancy rate (PR) which was lower with adding r-HMG 41.66% VS 50 % with r-FSH alone. We concluded that the combined use of r-HMG+r-FSH is effective as r-FSH alone in terms of oocytes' and embryos' quality while the effect on PR is still undetermined. © Annals of Tropical Medicine & Public Health S232 | Wolters Kluwer Medknow Publications | 17556783 | |

Because of the water shortage feeds the marshes during the last years, the re-flooded marshes began to dry again. The Al-Sanaf marsh is part of the Al Hammar marsh located in the Thi Qar province. It is not separated hydraulically from the Al Hammar marsh. The study suggested separating the two marshes by replacing the culverts under security dyke with uncontrolled weir to keep the area of Al-Sanaf marsh submerged. If there is any added water, it will cross from the suggested structure to the Al Hammar marsh. A hydrodynamic and water quality routing models (RMA2 and RMA4) were prepared based on mass conservation low, mass balance model, and four scenarios were applied for the Al-Sanaf marsh based on the incoming discharges. The suggested model was calibrated with field data measured in the marsh. The four suggested scenarios are to keep the requirement of the Al-Sanaf marsh restoration. The maximum submerged area of the marsh is 100 km2 under any operation conditions while this area was reduced to 72 km2 under low flow conditions (minimum inflow from the feeders). The three scenarios operated considering values of inflow from Euphrates River with the required inflow from Al Khamissiya canal to keep the minimum level of salinity in the submerged area. While the fourth scenario operated with the minimum value of discharge from all feeders. © 2019 Polish Society of Ecological Engineering (PTIE). | Polish Society of Ecological Engineering (PTIE) | 22998993 | |

A metal/semiconductor/metal structure was considered to attain plasmonic nanocavity with active region containing: QD, wetting layer and barrier. The dielectric function was calculated for both metal (Ag) and QD structure. The propagation constant of surface plasmon polariton (SPP) at the interface of Ag/InAs-QD structure was calculated and the dispersion relation of the plasmonic QD structure was evaluated. For frequencies far from plasma one, the gap between real and imaginary parts was large and a deviation from linear relation was obvious. The SPP field was strongly localized at the interface due to the effect of zero-dimensional QD structure which has application in the super-resolution and best sensitivity in optical imaging. Results of propagation length of SPP (Lspp) also support this. According to the Lspp results, the damping in the SPP energy was low in the Ag/InAs-QD compared to that in the Ag/air interface. The obtained results are in the range of experimental ones. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. | Springer New York LLC | 3068919 | |

Detecting k-complexes visually requires a highly qualified expert. In this study, an efficient method for detecting k-complexes from electroencephalogram (EEG) signals based on fractal and frequency features coupled with an ensemble model of three classifiers is presented. EEG signals are first partitioned into segments, using a sliding window technique. Then, each EEG segment is decomposed using a dual-tree complex wavelet transform (DT-CWT) to a set of real and imaginary parts. A total of 10 sub-bands are used based on four levels of decomposition, and the high sub-bands are considered in this research for feature extraction. Fractal and frequency features based on DT-CWT and Higuchi's algorithm are pulled out from each sub-band and then forwarded to an ensemble classifier to detect k-complexes. A twelve-feature set is finally used to detect the sleep EEG characteristics using the ensemble model. The ensemble model is designed using a combination of three classification techniques including a least square support vector machine (LS-SVM), k-means and Naïve Bayes. The proposed method for the detection of the k-complexes achieves an average accuracy rate of 97.3 %. The results from the ensemble classifier were compared with those by individual classifiers. Comparisons were also made with existing k-complexes detection approaches for which the same datasets were used. The results demonstrate that the proposed approach is efficient in identifying the k-complexes in EEG signals; it yields optimal results with a window size 0.5 s. It can be an effective tool for sleep stages classification and can be useful for doctors and neurologists for diagnosing sleep disorders. © 2019 IBRO | Elsevier Ltd | 3064522 | |

This paper proposes a new robust control scheme based on fuzzy system and Ant Colony Optimization algorithm. Adaptive fuzzy controllers (AFCs) based on Ant Colony Optimization (ACO) algorithm are proposed to eliminate the chattering phenomenon that occurs when the walking robot moves on rough surfaces. Six rotational joints are used to connect the seven links of the bipedal walking robot. Those joints are assumed frictionless and actuated by six independent servomotors. Therefore, six adaptive fuzzy controllers are designed in this work (one for each joint). To design robust fuzzy controllers, the Ant Colony Optimization algorithm is utilized to tune and find the best parameters of the output membership function of the fuzzy controller. For comparison purposes, optimal PID controllers (OPIDCs) are designed with optimal parameters that are chosen by utilizing the Ant colony algorithm. The performances of the two proposed controllers (AFCs and OPIDCs) are tested under significant disturbances situations such as carrying different weighted things by the walking biped robot. In addition, the stability of the adaptive fuzzy controller is studied and proved by applying Lyapunov theory. © 2019, Shiraz University. | Springer International Publishing | 22286179 | |

This paper studied numerically the potential for reduction in energy consumption for cooling and heating loads for a residence equipped with an EAHE system in the climate of Nasiriya city, which is located in southern Iraq and at 31.7°N and 45.8°E, latitude and longitude, respectively. Also, this paper presents a study about the thermal performance of three types of EAHE systems, system 1, consisting of one layer of EAHE and buried at an available area of house garden with 3-m depth, system 2, at the same site of system 1, but with two layers of EAHE at two depths, 3 and 4 m, and finally, system 3, buried along the area of the house at a depth of 3 m. First, the built numerical model was validated against experimental results, and the results of the comparison showed good agreement. The electricity consumption for cooling and heating of the house is calculated with and without the EAHE system. The results showed that with using EAHE, there is a considerable saving in energy and saving in the cost of electricity consumption, which reached 376 329 IQD ($301.11) over 1 year for system 2. © 2019 Wiley Periodicals, Inc. | John Wiley and Sons Inc. | 10992871 | |

This paper presents an evaluation of the structural behavior of CFST short columns strengthened by external and internal continuous spirals. A total of 16 CFST specimens were tested under axial compression. Specimens were stiffened as follows: (1) external continuous spiral (ECS) welded to the exterior surface of the steel tube, (2) internal continuous spiral (ICS) welded to the interior surface of the steel tube, and (3) unwelded internal continuous spiral (UICS) placed longitudinally inside the steel tube. Self-compacting concrete (SCC) was used in the experimental study. The main parameters in this study are the diameter of spiral bar, the number of spiral turns, and the location of the continuous spiral. From the test results, it was concluded that toughness, elastic strength, and ductility were improved significantly as a result of stiffening the CFST columns by external and internal spirals. ECS, ICS, and UICS improved the compression capacity up to 46.8%, 48.7%, and 47.9%, respectively, as compared with the control specimen. A theoretical model to estimate the ultimate load of stiffened CFST columns was developed and close correlations were found between the model and the experimental results. © 2019 Institution of Structural Engineers | Elsevier Ltd | 23520124 | |

A metal/semiconductor/metal (MSM) structure was considered to attain plasmonic nanocavity. The active region (semiconductor layers) contains the following: QD, wetting layer (WL), and barrier layers. Band alignment between layers was used to predict their parameters. Momentum matrix element for transverse magnetic (TM) mode in QD structure was formulated. Waveguide Fermi energy was introduced and formulated, for the first time, in this work to cover the waveguide contribution (Ag metal layer) in addition to the active region. The high net modal gain was obtained when the waveguide Fermi energy was considered which meant that the increment comes from the material gain, not from the confinement factor. The obtained results were reasoned the high gain due to the change in waveguide Fermi energy in the valence band, where the valence band QD states are fully occupied that are referring to an efficient hole contribution. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. | Springer | 15571955 | |

In particular, the average secrecy capacity, secure outage probability (SOP), the lower bound of SOP (SOPL), and the probability of strictly positive secrecy capacity are derived by using the classic Wyner's wiretap model. Two different scenarios for the fading parameters, namely, μ and m, which represent the real extension of the number of the multipath clusters and the shadowing index, respectively, have been studied. These parameters are chosen first as arbitrary numbers, thus the performance metrics are given in exact closed-form in terms of the extended generalised bivariate Fox's Hfunction that has been widely implemented in the open literature using various software packages. In the second scenario, both the fading parameters are assumed to be integer numbers to obtain the derived results in simple exact closed-form mathematically tractable expressions in terms of some analytic functions. The numerical results of this analysis are verified via the Monte Carlo simulations. © The Institution of Engineering and Technology 2019. | Institution of Engineering and Technology | 17518628 | |

We investigated the Freon gas, R22, belonging to the group of Hydrochlorofluorocarbons considered to be very dangerous, due to their role in destructing of layer, and discussed the adsorption of R22 on the surface of pristine, one Al-atom and two Al-atoms doped Graphene Nanoflakes (GNFs). Besides, we have studied theoretically the geometrical optimization, electronic properties and adsorption of undoped and doped Graphene Nanoflakes. All calculations are based on the density functional theory (DFT). Results show that adding one atom or two atoms of aluminum to GNFs causes a big decrease in the energy gap; at the adsorption of Freon R22 molecules by two Al-atoms doped GNFs, the structure becomes less gas-sensitive than one Al-atom doped GNFs. The band gaps, density of states (DOS), dipole moments, total energies, highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies have been calculated for undoped and doped with Al GNFs either with or without the Freon R22 gas molecules. © 2019, Pleiades Publishing, Ltd. | Pleiades Publishing | 19907931 | |

Identifying cytopathic effect and using it as a investigative tool needs much practice in observing stained section of numerous cell types. The present study aimed at diagnosing the histological changes in the malignant breast tissue, which caused by the HPV and comparing them with malignant breast tissue caused by other factors in order to find a way to diagnose the virus through the histopathic effect. A total of 100 samples was included in the study, 20 from benign tumor and 80 carcinomas, including different histopathological change. HPV was detected by using the conventional PCR. The breast cancer sections were examined for the expression of the effect of Human papillomavirus. In separate series the results of using formalin-fixed, paraffin -embedded sections were compared. Overall prevalence of HPV in malignant breast tissue was difference, we found that the histopathological characteristics of HPVassociated breast cancer are very different to breast cancercaused by other factors. Specifically, we showed the presence of HPV in breast cancer associates with the adenocarcinoma, The virus caused more activity in the tumor. Tumor is acinar carcinoma with increased cellularty and proliferative, While, in none infected with virus, there is no increased in cellularty or acinar, in some arease there was dilution of ducts.The observations indicate a likely causal role of HPV in causing a different histopathological change than breast cancercaused by other factors, This helps in the diagnosing of the HPV through cytopathic effect. © 2019 IOP Publishing Ltd.

Free radicals have been defined as intermediates of some biological redox reactions necessary for the maintenance of life. In presence of a free radical initiator and oxygen they may be oxidized this leading to lipid peroxidation, as it was suggested, might be associated with running out of hydrogen. In particular lipid peroxidation measured as levels of malondialdehyde (MDA). Glutathione (GSH), an intracellular thiol causes the eradication of free radicals or reduction in hydrogen peroxide level on state of oxidative stress. Decrease in the reduced GSH level has been reported in the erythrocyte of diabetics. Decrease in the level of GSH occurs both due to the competition between aldose reductase and glutathione reductase for NADPH, a cofactor, and increased oxidative stress (increased ratio of NADH/NAD). This study was conducted on 60 subjects. Informed consent was obtained from each person who agreed to participate in this study, while the survey was based on standardized interviews and questionnaire. Subjects were grouped as type 2-diabetics and healthy control with fasting plasma glucose (FPG) < 5.50 mmol/L. The ages ranged from 18 to 50 years. Glucose was determined by an enzymatic colorimetric test on basis of Trinder-Reaction. MDA was performed as described by Lipid Peroxidation Assay Kit (Colorimetric/Fluorometric), while the levels of GSH in all subjects were measured by the DetectX® Glutathione kit. The results show a significant elevation (P ≤ 0.05) in levels of glucose and MDA of type 2-diabetic patients in comparison with healthy subjects, which reached to 16.30 ± 0.50 mmol/L and 0.87 ± 0.19 nmol/mL for the type 2-diabetic patients, and 4.60 ± 0.15mmol L and 0.29 ± 0.5 nmol/mL for the control group, respectively. Also, it has been found a significant decrease (P ≤ 0.05) in GSH levels in type 2-diabetic patients, which reached to 3.43 ± 0.91 μM/mL in comparison with the control group which reached to 6.13±0.21 μM/mL. In conclusion we can observe that the increase in glucose levels leads to free radical formation by auto-oxidation and increase in lipid peroxidation (MDA levels), and inadequate antioxidant defense can occur during DM. In addition, GSH deficiency will make the present state worse by increasing the oxidative stress, since GSH is an important antioxidant. © 2019 Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

A metal/semiconductor/metal (MSM) structure was considered to attain plasmonic nanocavity with active region contains: QDs, wetting layer (WL) and barrier layers. Band alignment between layers was used to predict their parameters. Momentum matrix element for transverse magnetic (TM) mode in QD structure was formulated. Waveguide Fermi energy was introduced and formulated, for the first time, in this work to cover the waveguide contribution (Ag metal layer) in addition to the active region. Giant net modal gain was obtained when the waveguide Fermi energy was taken into account which means that the increment comes from the material gain not from the confinement factor. The change in waveguide Fermi energy in the valence band explained the high net modal gain, where the valence band QD states are fully occupied referring to an efficient hole contribution. © 2019 Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

Toachieve this mission the presence of E.coli was investigated as hygienic, quality indicator of raw milk also,phylogrouping, biofilm production ability and antibiogram was employed. Thus 54 raw milk samples were collected from two levels (markets and farms) at Al –Nasiriyah city south of Iraq, in period from January to March 2018. Traditional cultural and biochemical methods were used to isolate and identify E.coli, while molecular method (Cleremont method) was used to determine phylogenetic groups. E.coli was detected in 15 samples (27.8%), recovery percentage was significantly higher (40.7%) at market than farm (14.8%). Phylogenetic analysis revealed that all isolated strains were belong to two phylogroups;A (53.4%) and B2 (46.6%). According to the source of isolation phylogroup B2 was found only at market level, while phylogroup A was found in both market and farmlevel. This study found that most strains of phylogroup B2 (83.4%) were strong biofilm producer and harbor a potential antibiotics resistance to commonly used antibiotics, as determine in this study the poor hygienic practice of entire process beginning from milking through transporting to selling at market was responsible of contamination of milk with pathogenic strains that belong to phylogroup B2 which is mostly probably come from human source.In conclusion the raw milk constitute a serious public health threat to people who consumed raw milk. © 2019, Advanced Scientific Research.

Fifty (25 leukocytospermic vs. 25 non leukocytospermic) infertile couples collected from Al-Hussein Teaching Hospital/ Thi-qar Health Directorate enrolled in this study and semen samples were analyzed before and after in vitro sperm preparation technique. Furthermore, sperm concentration, sperm motility, progressive sperm motility, normal sperm morphology, and seminal leukocytes counts were evaluated according to standard WHO criteria (2010). For preparation technique, sperm prepared and incubated for 30 minute in 5% CO2 at 37°C. The results of present study shows that leukocytospermic men significantly (P<0.001) decreased and differences sperm functions compared with non leukocytospermic men may be due to reactive oxygen species generation by leukocytes. It was concluded that the increase seminal leukocyte counts lead to impaired sperm parameters and decrease fertilizing ability of human spermatozoa and sperm function improved and augmented after sperm processing technique. Further studies are recommended to assess the harmful outcomes of ROS on DNA damage and embryo quality after intracytoplasmic sperm injection (ICSI-ET). © 2019, Indian Journal of Forensic Medicine and Toxicology.

Studies show that about 1% of the world's population suffers from this disorder [1]. Epilepsy can be diagnosed by studying the electroencephalogram (EEG)signals, i.e. the electrical signals emitted from the brain and represent its activity. This paper proposed an epileptic seizures detection based on analysis of EEG signals. The detection is carried out firstly recording the EEG signals using the EEG device. The noise is then eliminated before features extraction process is carried out using HOS-WPD. These features are then used to train two classifiers, namely Navie Bayes and FFNN, by which the signals are classified as either benign or seizure. Experimental evaluation was carried out to compare the detection performance of both algorithms in terms of Precision, Recall, and Accuracy and using MIT BIH Dataset. © 2019 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The current study consisted of modeling 18 soil samples at three depths per area for 6 districts of the central, south, west, and eastern parts of Shatrah, northeast of Thi-Qar governorate, to determine the relationship between depth, pH, organic matter ratio and concentration of heavy elements in the soil. The results showed that the concentration of the three elements was high when compared to global rates of Pb (67.99 ppm), Cd (4.61 ppm) and Zn (68.64 ppm); the severity of adverse events was responded dramatically in a pH-time-concentration-dependent manner. Based on our results, in addition to the role of the human activities, the proportion of organic matter, pH, with the age and depth of soil plays a critical role to excess the pollution and toxicity of heavy elements. © 2019, Indian Journal of Forensic Medicine and Toxicology.

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | High-fidelity large eddy simulations (LES) were conducted to characterize the spatial and temporal structure of turbulent flows in an industrial-sized Francis turbine while the unit operated at the design point and partial load. A pressure surge with an amplitude of 8% of the turbine head was observed at partial load while the amplitude was <1% at the design point. The vortex rope precession observed in the draft tube correlated to the amplitude and frequency of the pressure surge. Central and peripheral water injections at various volumetric rates were considered to control the flow-induced pressure fluctuations. Central injection at the 4% and 6% flow rates attenuated high amplitude pressure fluctuations by 40% and 75% respectively at partial load. At the same operating conditions, peripheral injections did not have the same desired effect. Although power generation was not changed with water injection at the design point, it was reduced by about 2.5% by central injection and 0.5% by peripheral injection at partial load, showing a water injection mitigation strategy could be applied without any penalty. © 2019 | Elsevier B.V. | 0142727X | |

Based on the increasing need for reliable image encryption this paper presents a new method which combines the Haar wavelet transform with the Advanced Encryption Standard (AES) and pixel shuffling based on a chaotic logistic map. In the proposed method the Haar wavelet transform is calculated from the original image to obtain the different frequency domains of the image, namely, the approximation coefficient (LL) and detail confidents (LH, HL and HH). The approximation part (LL) is then encrypted by using the AES algorithm to create the image diffusion and the inverse of the Haar wavelet transform is applied. To further enhance the encryption strength a chaotic logistic map is used to shuffle the resulting image thereby making a malicious reconstruction attempt very challenging. The proposed method was evaluated in an extensive set of tests and compared to several representative methods from the literature. Test results show that it performed well across a variety of images and achieved a better level of image encryption and a lower level of image degradation. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. | Springer New York LLC | 13807501 | |

Here, the authors investigate the effects of using the ‘Satelliting’ technique on the deposition and characteristics of A6061-TiC coatings fabricated by cold-spray. The results showed clear improvements in the deposition efficiency and porosity of the satellited powder obtained by using the satellited feedstock. Annealing heat-treatment was then applied for further enhancement of the coating's density and wear properties. The heat-treated coating exhibited a ~70% reduction in interlamellar porosity. Dry sliding wear testing using a steel counter body at 5 N showed that using a satellited feedstock with TiC yielded a 55% and 20% reduction in coating specific wear rate in comparison to coatings made using pure 6061 and blended 6061-TiC, respectively. This was further reduced by ~70% and 40% in comparison to the 6061 and blended 6061-TiC coating after heat-treatment with good repeatability. © 2019 | Elsevier B.V. | 2578972 | |

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | Simulations have been conducted to quantify the effects of aspect ratio on the lift and drag coefficient for a finite plate near a free surface. Large eddy simulations using a VOF multiphase model were conducted for a plate length to height aspect ratio of 2.5, 5 and 10 for a Reynolds number of 50,000 and a Froude number of 1.3. Eulerian and Lagrangian coherent structures were employed to characterize the turbulent flow fields. As the aspect ratio increases, the mean drag coefficient decreases from 1.88 to 1.73. This is due to an increase in vortex activity caused by separation of the free shear layer at L/D of 5 and 10. Both the upstream and downstream region are affected by the hairpin-like vortices generated from the bursting of the free shear layer. With increasing plate length, Karman vortex shedding from the face near the free surface is suppressed, and the influence of tip vortices on the near wake flow is reduced. The aspect ratio has a strong influence on the free surface shape and dynamics because surface deflections increase with L/D. Free surface flows studied here provide valuable insight into designing off-shore structures, platforms, hydraulic and marine-current energy harvesting devices. © 2019 Elsevier Ltd | Elsevier Ltd | 298018 | |

BOX 2454, Ryad, 11451, Saudi Arabia | The paper presents a new analytical method called the local fractional Laplace variational iteration method (LFLVIM), which is a combination of the local fractional Laplace transform (LFLT) and the local fractional variational iteration method (LFVIM), for solving the two-dimensional Helmholtz and coupled Helmholtz equations with local fractional derivative operators (LFDOs). The operators are taken in the local fractional sense. Two test problems are presented to demonstrate the efficiency and the accuracy of the proposed method. The approximate solutions obtained are compared with the results obtained by the local fractional Laplace decomposition method (LFLDM). The results reveal that the LFLVIM is very effective and convenient to solve linear and nonlinear PDEs. © 2019 by the authors. Licensee MDPI, Basel, Switzerland. | MDPI AG | 25043110 | |

The mathematical calculations and system simulation are performed for a converter with nominal power of 400 MW and 400KV DC. The characteristic of Swiss rectifier including the operation principle, modulation strategy and relevant equations are described in detail. The MMC is used as a combination with Swiss rectifier because of its simplicity to be integrated for applications that required different level of voltages and currents, such as offshore wind turbine. Where, there is a trend to generate the electricity and transmit it in DC form due to its economic reasons. Therefore, the usage of MMC-Swiss rectifier is viable for High Voltage Direct Current HVDC applications. The contribution of Swiss rectifier is to make the current drawn from the supply by a converter, pure sinusoidal and this achieved by injecting third harmonic current in the circulating current from the DC side. Thus, this would reduce the THD and improve the power quality of the AC side currents. © 2017 American Psychological Association. | International University of Sarajevo | 23034521 | |

Although Fresh garlic juice (GJ) and Garlic oil (GO) were reported to possess antibacterial activity, the mechanism that underlay the garlic antimicrobial activity still obscure. Method: The hypothesis of my study is to examine the antimicrobial activities of GJ and GO and the combination of either GJ or GO with Amp and CF, respectively. Results: In my current project, the antibacterial activity of GJ was found to be significant in reducing the bacterial protein synthesis against E.coli, while GO negatively correlated; but, unfortunately, did not reach the significant level. Moreover, GJ and GO were correlated with improvement of the sensitivity of bacteria to antibiotics. Conclusion: further investigation of the potency of GJ and GO in treating the infections is highly needed. © 2019, Indian Journal of Public Health Research and Development.

These containers were immersed in the transformer oil. A 100 kVA transformer was used as a model for study because these transformers are widely used in the electricity distribution network in Iraq. As temperature rises, the phase change material (paraffin wax) absorbs heat and melts inside the containers at a constant temperature. This feature can be utilized to store heat for a period until the temperature for weather drops; then this heat is rejected, and the wax begins to solidify. In this experiment, five containers were used, each containing 2 kg of wax. The results showed a clear decrease in the temperature of the oil, which led to the enhancment of its thermal insulation and kept the oil from failure and the preserved the transformer from breakdown. The results showed that the reduction in temperature is approximately 7°C and the reduction increased upon increasing the amount of wax added. © 2019 Wiley Periodicals, Inc. | John Wiley and Sons Inc | 10992871 | |

Developing an artificial intelligence system that can adequately identify these affected regions can support the clinical diagnosis of brain disease. In this study, we develop a new model called a fractal dimension (FD) of the undirected graph (NG) based on a sine cosine driven support vector machine (FD-NG model utilising the SCA-SVM) algorithm for identifying the focal and non-focal EEG signals. Each EEG signal is partitioned into its respective segments and each segment is divided into clusters using a sliding window technique. To reduce the dimensionality of each cluster, a set of best features is extracted. Three types of input features are considered: linear features (LF), statistical features (SF), and features based on time domain (TD). These are investigated and extracted from each cluster. As a result, each EEG signal is represented by a series of reduced segments and is then forwarded to the proposed FD-NG based SCA-SVM model. The model considers each segment as a node and a link is built between each pair of nodes based on their degree of similarity. The FD of graphs are used as inputs to the SCA-SVM model to classify the EEG signal into FC and NFC components.

The five cities are namely: Al-Nassriya, Al-Shatra, Al-Rifai, Suk Al-Shoyokh, and Al-Chibayish. In general, the results revealed that the average generation rate of domestic solid waste was 0.85 Kg/capita/day in the study area. The organic waste was found the major components of municipal waste and it exceeded 60% of waste composition. All dumping sites in the aforementioned cities are uncontrolled dumpsite, their design not suitable, and do not work according to proper operating standards. There are no landfills or dumping sites specified for disposal the non-municipal waste. The investigations showed the presence of potential health risks and negative environmental aspects of solid waste handling in Thi-Qar governorate due to improper handling of collection, transfer, and disposal of solid waste. Thus, developing a master plan for integrated solid waste management is prerequisite to overcome the difficulties solid waste management sector in Thi-Qar governorate. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

An amperometric glucose biosensor was fabricated by the immobilization of glucose oxidase (GOx) onto the synthesised PAA-VS-PANI/GPL-FePc-CH (where VS-PANI is vinyl substituted polyaniline). Scanning electron microscopy reveals the presence of three dimensional microporous structure with estimated pore size of 19 μm. The 5-(trifluoromethyl)-2-mercaptopyridine substitution onto FePc enabled the solubility of FePc in water and controls the aggregation of GPL-FePc in the synthesised CH. A sharp peak around 699 nm in UV–visible spectra confirms the presence of incorporated GPL-FePc into CH. Cyclic voltammogram of the synthesised CH biosensor exhibited well defined redox peaks with a ΔEp value of 0.26 V in Fe(CN)6 3-/4- bench mark solution. The fabricated PAA-VS-PANI/GPL-FePc/GOx-CH amperometric biosensor resulted in remarkable detection sensitivity of 18.11 μA mM−1 cm−2 with an average response time of ∼1 s, linearity from 1 to 20 mM, and low detection limit of 6.4 μM for the determination of glucose. © 2019 Elsevier B.V. | Elsevier Ltd | 9565663 | |

Also in recent years, in 1988, a new cardiac natriuretic peptide [B-type natriuretic peptide (BNP)] with excellent diagnostic characteristics was discovered. Wherefore, in the next years was appeared to have prognostic properties and later likewise seemed to have symptomatic properties in the out-patient settings and emergency department. In this research we completed work with participants, part of them patients with heart failure to varying degrees and another part do not suffer from heart failure to be a control group on which to build the results of the research. We pulled the blood from them, turned it to serum, estimated concentrations of certain chemical agents that are under research such as (BNP, hs-CRP, T-Chol, HDL-cholesterol, TG, LDL-cholesterol and VLDL-cholesterol) and compared these concentrations with another factor (EF %). Generally, we found a clear increase in concentrations of BNP and hs-CRP (Percentage increase in BNP and hs-CRP concentration level is estimated at 497%, 332% which is 5, 3.32 times as much as the BNP and hs-CRP concentration in control group D respectively), with the greater decline in the value of EF%. As well as compared to other factors (Percentage increase in T-Chol, TG, LDL-cholesterol, VLDL-cholesterol and percentage decrease in HDL-cholesterol,). Therefore, the BNP and hs-CRP are the two best factors of the total factors studied in the research to diagnose heart failure disease. © 2019, Indian Journal of Public Health Research and Development.

Immune modulation in the host by parasitic antigens is an integral part of this disease. The current study attempts to dissect the immune responses of aminoacyl-tRNA synthetases (AARS) with emphasis on Brugia malayi asparaginyl-tRNA synthetase (BmAsnRS), since it is one among the highly expressed excretory/secretory proteins expressed in all stages of the parasite life cycle, whereas its role in filarial pathology has not been elaborately studied. Methods and Results: In this study, recombinant BmAsnRS (rBmAsnRS) immunological effects were studied in semipermissive filarial animal model Balb/c mice and on clinically defined human samples for LF. In mice study, humoral responses showed considerable titer levels with IgG2a isotype followed by IgG2b and IgG1. Immunoreactivity studies with clinical samples showed significant humoral responses especially in endemic normal with marked levels of IgG1 and IgG2 followed by IgG3. The cell-mediated immune response, evaluated by splenocytes and peripheral blood mononuclear cells proliferation, did not yield significant difference when compared with control groups. Cytokine profiling and qRT-PCR analysis of mice samples immunized with rBmAsnRS showed elevated levels of IFN-γ, IL-10, inhibitory factor-cytotoxic T lymphocyte-associated protein-A (CTLA-4) and Treg cell marker-Forkhead Box P3 (FoxP3). Conclusions: These observations suggest that rBmAsnRS has immunomodulatory effects with modified Th2 response along with suppressed cellular proliferation indicating the essence of this molecule for immune evasion by the parasite. © 2019, Mary Ann Liebert, Inc. | Mary Ann Liebert Inc. | 15396851 | |

Received Signal Strength (RSS)-based fingerprinting approaches have been widely used for positioning inside buildings because they have a distinct advantage of low cost over other indoor positioning techniques. The signal power RSS is a function of the distance between the Mobile System (MS) and Access Point (AP), which varies due to the multipath propagation phenomenon and human body blockage. Furthermore, fingerprinting approaches have several disadvantages such as labor cost, diversity (in signals and environment), and computational cost. Eliminating redundancy by ruling out non-informative APs not only reduces the computation time, but also improves the performance of IPS. In this article, we propose a dimensionality reduction technique in a multiple service set identifier-based indoor positioning system with Multiple Service Set Identifiers (MSSIDs), which means that each AP can be configured to transmit N signals instead of one signal, to serve different kinds of clients simultaneously. Therefore, we investigated various kinds of approaches for the selection of informative APs such as spatial variance, strongest APs, and random selection. These approaches were tested using two clustering techniques including K-means and Fuzzy C-means. Performance evaluation was focused on two elements, the number of informative APs versus the accuracy of the proposed system. To assess the proposed system, real data was acquired from within the College of Engineering and Applied Sciences (CEAS) at the Western Michigan University (WMU) building. The results exhibit the superiority of fused Multiple Service Set Identifiers (MSSID) performance over the single SSID. Moreover, the results report that the proposed system achieves a positioning accuracy < 0.85 m over 3000 m2, with an accumulative density function (CDF) of 88% with a distance error of 2 m. © 2019 by the authors. | MDPI AG | 20763417 | |

I investigated the synchronization quality by using the rate equations model. In both open-loop system and closed-loop system, the direct current modulation in transmitter laser and receiver laser has significant effects on the correlation coefficient. In both cases, we can use the direct current modulation to minimize the effect of mismatch in delay times on the synchronization quality. Also, the effect of modulation frequency in lasers has been analyzed. The correlation coefficient has a high value with increasing the modulation frequency in both lasers. Furthermore, the present results indicate that the correlation coefficient tends to high values at the negative value of the difference in the modulation frequency between the lasers in comparison with the positive value of the difference. The correlation coefficient has different behaviors when the delay time in transmitter laser is larger than the delay time in receiver laser or vice versa. © 2019, Shiraz University. | Springer International Publishing | 10286276 | |

This paper presents an attempt to study the possibility of combining the external confinement using reinforcing rings and the internal stiffening using reinforcing bars for strengthening CFST columns. In order to investigate the structural performance of the proposed combination method, a total of 18 specimens were tested under axial compression. These specimens were strengthened using three different methods: confinement in the form of external reinforcing rings (ERRs), stiffening in the form of internal reinforcing bars (IRBs), and a combination of both methods. For all tested specimens, the thickness of steel tube, outer diameter, and tube length were 4.15 mm, 114.3 mm, and 260 mm, respectively. CFST specimens were filled using self-compacting concrete (SCC) of normal compressive strength. The main parameters considered in the test procedure are the spacing between the ERRs, the number of IRBs, and a combination of the ERRs spacing and the number of IRBs. The experimental results show that the proposed combination method is more effective to improve the structural performance of short CFST columns compared to using only ERRs or IRBs. Further improvement is achieved when the spacing between the ERRs decreases and the number of IRBs increases. The proposed combination method increases the compressive load-carrying capacity up to 27.2% and 57.4% compared to ERRs and IRBs, respectively. It deserves noting that the proposed combination method, ERRs, and IRBs improve the compressive load-carrying capacity up to 120.3%, 93.5%, and 40%, respectively, compared to the control specimen. In addition, specimens strengthened by the proposed combination method show an excellent ductility behavior. © 2019 Institution of Structural Engineers | Elsevier Ltd | 23520124 | |

This study tends to evaluate the role of BNP as a predictor of left ventricular function among patient with chronic renal failure on maintenance hemodialysis. Methods: This is a perspective cross-sectional study, including 89 (45 males and 44 females) patients on maintenance hemodialysis followed up for six months. BNP level, glomerular filtration and body mass index of the patients were measured and left ventricular function (EF%) was detected by echocardiography at the start of the study and after three and six months between October 2016 and April 2017.Results:Of 89 patients, 13 were underweight, 56 had a healthy weight, and 20 were overweight. There was a significant negative association between BNP level and both EF% and BMI (P<0.001, P<0.001) respectively. During the follow up of these patients there was a clear trend for BNP to be higher among patients with impaired left the ventricular function. There was also a strong inverse association between BNP level and GFR (P <0.001).Conclusion: BNP levels show a strong inverse association with EF%, BMI and GFR in patients with CRF. Currently, BNP widely used by most health institutions to predict left ventricular function. However, both BMI and GFR considered a significant confounder of BNP measurement in patients with compromised renal status. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

Rehabilitation includes time consuming and repetitive exercises which are costly and demotivating as well as the requirements of clinic attending and direct supervision of physiotherapist. In this work, the system consists of a graphical user interface (GUI) on a smartphone screen to instruct and motivate the patients to do their exercises by themselves. Through the GUI, the patients are instructed to do a sequence of exercises step by step, and the system measures the electrical activities (electromyographic signals EMG) of the user's forearm muscles by Myo armband. Depending on database, the system can tell whether the patients have done correct movements or not. If a correct movement is detected, the system will inform the user through the GUI and move to the next exercise. For preliminary results, the system was extensively tested on a healthy person. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

Use disintegrant is considered one of corner stone to achieve pharmaceutical tablets that meet requirements of recommended tablet formulation in the markets. Sodium Starch Glycolate as an elastic material (super disintegrant) is the component of compacted tablets by direct compression in current work. Uniaxial compaction process was implemented by utilizing a universal testing machine. The tablets were compacted under applied load ranging from 75 to 375 MPa. A 13 mm diameter cylindrical die was used to characterize the compression behaviour of the 1.0 ± 0.01 g of material. Number of the evidences from this study is, the tabletted powder characteristics and the volume-pressure measurements relationship were investigated. The recommended tablet formulations were evaluated by using elastic relaxation, indirect tensile strength, friability, and disintegration tests. Applying load higher than 150 Mpa produces compacts with a longer disintegration time, low elastic relaxation, in addition to tensile strength and friability percentage identical to recommended tablets formulation in the markets. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

This study focused on converting Zubair Oil Field Gas turbine (ALSTOM GT13E2) from single cycle into a combined cycle power plant. Models suggestion design have been presented with back-pressure steam turbine by Cycle-Tempo (5.1) thermodynamics simulation program, which presents value diagram and exergy flow diagram both are useful to understanding the thermodynamic performance of complicated systems.The result of exergy analysis explicate that huge amount of exergy loss firstly occurs in gas turbine combustor (about 60% due to high irreversibility), and heat recovery steam generation (HRSG) is the second major exergy loss in combined cycle power plant (about 30%) recently apparatus concepts less than 10% of exergy (like compressors and expanders). Also, in this study explained the effect of changing the ambient temperature on the performance of power plant by using four temperature parameters on the four simulation models at constant compression ratio. The results were the increase in gas turbine temperature inlet led to decrease the net power output of the CCPPs. Thermal and exergy efficiencies increase when ambient temperature increase due to growth turbine inlet temperature but this temperature restricted by creep rupture and thermal fatigue for combustor parts and turbine blades metal. Maximum thermal and exergy efficiencies can be reached to 55.74, 53.28% respectively at worst ambient temperature. The calculation results in this study were compared with two previous studies, with considerable differences in input parameters of the gas turbine and steam turbine also, the types of the gas turbine models. finally, the results showed acceptable agreement. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

Today, available chemical drugs have shown severe complications during hydatid cyst surgery. Here we investigated theefficacy and safety of Curcuma longa (C. longa) essential oil (CLEO) against hydatid cysts protoscoleces. Methods: Here, the collected protoscoleces from fertile hydatid cysts were exposed to different concentrations of the CLEO (50-200 μl/mL) for 5-30 min in vitro and ex vivo. In addition, male NIH mice (48 mice) were applied to examine the safety of CLEO. Results: All protoscoleces were completely killed in 5th min of treatment to the doses of 200 μl /mL of CLEO. On the other hand, in the 10th min of treatment, CLEO entirely killed 100% of protoscoleces at the dose of 100 μL/mL. Other doses of CLEO, but, revealed a postponed activity. Although CLEO at the doses of 50, and 100 μL/mL exhibited no similar effect in the ex vivo analysis; but, at the dose of 200 μL/mL and an exposure time of 5 min, approximately 100% of protoscoleces were destroyed into the cyst. We found that after intra-peritoneal injection of the CLEO for 14 days, although blood and biochemical parameters were changed; but there was no significant difference in comparison with the control group (p > 0.05). Conclusion: This research demonstrated that C. longa revealed the promising scolicidal effects against protoscoleces in vitro and in vivo, of course, after additional tests; it might be considered as an herbal scolicidal drug in order to decrease the threat of discharge of protoscoleces through hydatid cyst surgery. Nevertheless, supplementary studies will be desired to prove the current findings by examination the essential oil in a clinical setting. © 2019 The Author(s). | BioMed Central Ltd. | 14726882 | |

Vibrational spectroscopy, such as Raman scattering, provides high chemical selectivity but is limited by weak signals and a large fluorescence background. Fluorescence imaging is often used by introducing specific dyes in biological systems to label different system parts and to increase the image contrast. However, the extrinsic fluorescence of the staining molecules often masks the intrinsic vibrational signals of biomolecules, which could also be simultaneously detected using the same excitation laser source. Therefore, fluorescence staining is often accompanied by the loss of other important complimentary information. For example, the high laser power often used for the rapid, high-quality imaging could lead to photo-induced suppression or bleaching of the fluorescence and Raman signals resulting in sample photodamage. Therefore, simultaneous imaging and photodamage analysis need to be performed in a controlled bioimaging experiment. Here we perform simultaneous spectroscopic bioimaging and photostability analysis of rhodamine 6G (R6G) stained red blood cells (RBCs) using both fluorescence and resonance Raman imaging in a single 532 nm laser excitation experiment. We develop a corresponding data processing algorithm which allows separation of the two spectroscopic signals. We control the relative intensity of the R6G and RBC signals by varying the excitation laser power and simultaneously monitor the photostability of RBCs. We observe no significant photodamage of RBCs through the absence of changes in the relative Raman peak intensities. Conversely, the R6G molecules show bleaching with the suppression of both the fluorescence and resonance Raman signals. Our approach may be generalized to other types of stained cells with the appropriate selection of fluorescent dyes and excitation sources. © 2019 The Royal Society of Chemistry. | Royal Society of Chemistry | 32654 | |

Blood CA15-3, Prolactin hormone, and Lactate dehydrogenase enzyme levels were determined in 65 Women with Breast Cancer and 55 apparently healthy subjects. The levels of serum CA15-3, Prolactin hormone, and Lactate dehydrogenase enzyme were showing a significant increase in women with Breast Cancer in comparison to the control group (P ≤ 0.05). The study also investigates the correlation between the concentrations of the CA15-3 and each of Prolactin hormone, and Lactate dehydrogenase enzyme, However, we compared all measurement parameters according to the type of disease. In Breast cancer patients, we finding increase CA15-3, Prolactin hormone, and Lactate dehydrogenase enzyme can clearly occur, and we finding positive correlation relationship between CA15-3 and each of PRL and LDH through coefficient correlation (r). © 2019 Pharmascope Publications.

In this work, we demonstrate the use of super-resolution fluorescence microscopy for investigating and quantifying the antimicrobial effect of AgNPs at the molecular level. We found that subjecting Escherichia coli (E. coli) bacteria to AgNPs led to nanoscale reorganization of histone-like nucleoid structuring (H-NS) proteins, an essential nucleoid associated protein in bacteria. We observed that H-NS proteins formed denser and larger clusters at the center of the bacteria after exposure to AgNPs. We quantified the spatial reorganizations of H-NS proteins by examining the changes of various spatial parameters, including the inter-molecular distances and molecular densities. Clustering analysis based on Voronoi-tessellation were also performed to characterize the change of H-NS proteins' clustering behavior. We found that AgNP-treatment led to an increase in the fraction of H-NS proteins forming clusters. Similar effects were observed for bacteria exposed to Ag+ ions, suggesting that the release of Ag+ ions plays an important role in the toxicity of AgNPs. On the other hand, we observed that AgNPs with two surface coatings showed difference in the nanoscale reorganization of H-NS proteins, indicating that particle-specific effects also contribute to the antimicrobial activities of AgNPs. Our results suggested that H-NS proteins were significantly affected by AgNPs and Ag+ ions, which has been overlooked previously. In addition, we examined the dynamic motion of AgNPs that were attached to the surface of bacteria. We expect that the current methodology can be readily applied to broadly and quantitatively study the spatial reorganization of biological macromolecules at the scale of nanometers caused by metal nanoparticles, which are expected to shed new light on the antimicrobial mechanism of metal nanoparticles. © 2019 IOP Publishing Ltd. | Institute of Physics Publishing | 9574484 | |

The system that takes into account in the study is consisting of two rings connected in parallel, with the same type of atomic sites for pristine double metal ring, and with two different types of atomic sites for an alloyed double metal ring. The tight-binding method was used to calculate the energy spectrum and persistent current in presence of transverse flux. Our results show that the transverse flux causes bending of the persistent current and increase in current amplitude at the pristine double metal ring, while it leads to asymmetry at alloyed double metal ring. The energy gap is not affected by the transverse flux. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

Res. Lab. (NNRL), Science College, University of Thi-Qar, Nassiriya, Iraq | This work studies the gain from quantum dot plasmonic nanolaser. A metal/semiconductor/metal structure was considered to attain plasmonic nanocavity with active region contains: quantum dot, wetting layer and barrier layers. Band alignment between layers was used to predict their parameters. Momentum matrix element for transverse magnetic mode in quantum dot structure was formulated. Waveguide Fermi energy was introduced and formulated, for the first time, in this work to cover the waveguide contribution (Ag metal layer) in addition to the active region. The gain obtained here overcomes the electron scattering losses which promises in high gain, high power and high speed applications. The waveguide Fermi energy goes deep in the valence band which explains the high gain, where it is shown that covering the structure by a metal makes valence band quantum dot states fully occupied which refers to an efficient hole contribution. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17426588 | |

This study is concerned with examining the effect of four sodium chloride concentrations (0, 25, 50 and 75 mM) and four trehalose sugar concentrations (0, 5, 10 and 15 gm. L-1) in some chemical characteristics of somatic embryos of date palm c.v Um - Aldehine in vitro. The results showed: That the increasing in sodium chloride concentration in culture media had a significant increase in the concentrations of carbohydrates and proline. In addition, the treatment (75 mM) of sodium chloride achieved the highest averages, also it has led to a significant decrease in proteins percentage. The effects of increasing trehalose sugar concentration in culture media has significantly increased the carbohydrates, proline and proteins. However, the treatment of (15 g. L-1) resulted the highest averages. The interaction treatment between sodium chloride (75 mM) and trehalose sugar (15 g.L-1) has significantly increased the carbohydrates and proline. The added concentrations of trehalose sugar to the culture media contributed to decreased the effects of salt stress, therefore, increased the tolerance of somatic embryos of date palm to the salt stress. © 2019, Indian Journal of Public Health Research and Development.

To improve the quality and reliability of control programs for CNC machines, a digital twin (DT) is proposed to be used. It performs virtual testing of a given grinding cycle for the possibility of defect occurrence at some combination of variable technological factors. To design the optimal grinding cycle by calculating the optimum trajectory of the radial feed change cycle, we propose the dynamic programming method (DPM) used in solving the classical transport problem, in which a network of roads with intermediate stations is specified. In the task it is necessary to find the optimal trajectory of transport. The conditions for the appearance of defects detected by the DT are introduced into the system of restrictions, and the feed cycle is again optimized in the DPM optimization system. A new optimized cycle is again tested by the DT. These iterations are repeated until the DT fixes the present of a defect for the operation. The methodology proposed in the article for the synthesis of digital twin and DPM technologies at the stage of preparation of control programs for CNC machines makes it possible to guarantee the maximum productivity of the grinding operation while ensuring the specified quality of the machined surface under varying processing conditions that vary within the specified limits. © 2019 Author(s). | Copernicus GmbH | 21919151 | |

This paper studies numerically the effect of some design parameters (pipe diameter, inlet condition, pipe length, and outlet condition) on the overall performance of the EAHE system. Four diameters of the EAHE pipe (2, 3, 4, and 6 in) are studied and this numerical study has been done for summer and winter seasons for Nasiriyah city in southern Iraq. First, the built numerical model was validated against the experimental model, and the results of comparison showed a good consensus. After the validation and by using computational fluid dynamics modeling, the overall performance of the EAHE system with all pipe diameters was analyzed with ranges of air velocity, DBT or inlet temperature, and a pipe length of 50 m. The simulated results showed that the EAHE system with 6 in pipe diameter has the best values of overall performance, but from the thermal performance point of view, the 2 in pipe diameter is more suitable. © 2019 Wiley Periodicals, Inc. | John Wiley and Sons Inc. | 10992871 | |

This study was designed to assess the level of awareness and knowledge of local residents concerning solid waste management in Al-Nassyriah City of Iraq. Primary data were collected from local residents through questionnaire and interview. A total of 1,794 questionnaires were completed by the respondents that were randomly selected from 12 suburban areas located in Al-Nassyriah City. A descriptive cross-sectional analysis was performed among local communities and results were analyzed by using SPSS software. Results from the survey showed that 67% of respondents were dissatisfied with the current practice of solid waste management in their city. The results also showed that low-level of knowledge on relevant laws and regulations pertaining to solid waste was observed among respondents. Although half of the respondents were aware about the importance of managing solid waste, however, most of them failed to put their knowledge and awareness into practice. Therefore, extensive and continuous efforts by various stakeholders are urgently needed to enhance public awareness towards sustainable solid waste management in developing countries, particularly in Al-Nassyriah City, Iraq. © 2019 Author(s). | American Institute of Physics Inc. | 0094243X | |

Several models were used to investigate the ionosphere conditions. These models use mainly two parameters to evaluate the perturbations in the ionosphere. These parameters are the electron density and TEC (Total Electron Content) which they control the ability of reflections frequencies in the ionosphere. The propagation characteristics were investigated. This paper uses four models to estimate the ionosphere perturbations. The goal of this paper was to choose the most efficient model that gives the best image that evaluates the ability of reflections shortwaves in the ionosphere.

Patients with unresectable primary or secondary liver malignancies have limited therapeutic options. Thus, treatment of such malignancies is challenging, and the demand for effective treatment remains high, even in the presence of systemic chemotherapy. Loco regional chemotherapy is a minimally invasive technique that allows the delivery of high dose chemotherapy with minimal extra-hepatic toxicity. Surgical isolated hepatic perfusion has been shown to be effective in patients with unresectable hepatic malignancies; however, its complexity, high complication rates and non-repeatability limit its global acceptance. Percutaneous hepatic perfusion is a novel method of delivering regional chemotherapy in a selective fashion to the liver. In addition, it is relatively less invasive and has a low rate of complications. This review article will illustrate the technique of percutaneous hepatic perfusion and will provide an overview about its safety and potential complications, then discussing the results of the selected relevant articles. © 2019, Kuwait Medical Association.

The studied system is consisting of two rings connected parallel, with two different types of atomic sites. This work contains two parts. First is an analytical study of calculation of the energy spectrum, persistent current, Drude weight and low-field magnetic susceptibility of ADMR by the tight-binding method. Second is a computation study of electronic properties of the alloyed double metal ring by density functional theory (DFT). The latter part is considered as a complementary study of what was studied in the first part in order to determine the best materials which will be used to design alloyed double metal ring.

This paper presents a statistical analysis of seven PDs proposed to model qc obtained through performing CPT for soil in Nasiriyah during the construction of a new refinery petrol station. Preliminary testing for suitability of the suggested distributions has used the method of moment ratio diagram (MRD) based on the Pearson system. It was found that the soil stratification has a large effect on the distance between every two points on MRD. The type of probability distribution was also affected, and changed, by increasing the number of data points for qc included in the analysis. Logistic and Weibull distributions are considered the best PDs that represent the qc of the first layer having thickness 12 m of clay soil, followed by the other distributions, while the logistic and normal distributions were considered the best PDs among the seven suggested distributions for the second layer of 8 m silty sand and clayey sand. All the suggested distribution can represent the given qc data approximately except the Rayleigh distribution. © 2018, Springer Nature Switzerland AG. | Springer International Publishing | 9603182 | |

The detection of k-complexes in electroencephalogram (EEG) signals based on visual inspection is time consuming, prone to errors, and requires well-trained knowledge. Many existing methods for k-complexes detection rely mainly on analyzing EEG signals in time and frequency domains. In this study, an efficient method is proposed to detect k-complexes from EEG signals based on fractal dimension (FD) of time frequency (T-F) images coupled with undirected graph features. Firstly, an EEG signal is partitioned into smaller segments using a sliding window technique. Each EEG segment is passed through a spectrogram of short time Fourier transform (STFT) to obtain the T-F images. Secondly, the box counting method is applied to each T-F image to discover the FDs in EEG signals. A vector of FD features are extracted from each T-F image and then mapped into an undirected graph. The structural properties of the graphs are used as the representative features of the original EEG signals for the input of a least square support vector machine (LS-SVM) classifier. Key graphic features are extracted from the undirected graphs. The extracted graph features are forwarded to the LS-SVM for classification. To investigate the classification ability of the proposed feature extraction combined with the LS-SVM classifier, the extracted features are also forwarded to a k-means classifier for comparison. The proposed method is compared with several existing k-complexes detection methods in which the same datasets were used. The findings of this study shows that the proposed method yields better classification results than other existing methods in the literature. An average accuracy of 97% for the detection of the k-complexes is obtained using the proposed method. The proposed method could lead to an efficient tool for the scoring of automatic sleep stages which could be useful for doctors and neurologists in the diagnosis and treatment of sleep disorders and for sleep research. © 2019 Al-Salman, Li and Wen. | Frontiers Media S.A. | 16625196 | |

Packed beds of near-spherical NaCl particles (ø2-2.8 mm) were infiltrated with liquid metal to produce the required samples. The brittle zinc alloy ZA-27 and ductile Aluminium (99% Al) were used as matrix materials. NaCl particles were retained inside half of these samples to replicate MSF containing high-strength particles. NaCl was leached from the remaining samples to investigate MSF with weak particles. This procedure ensured that all samples had a near-identical matrix geometry and microstructure, thus isolating the effect of particle strength. Quasi-static compression tests were conducted and significant changes in the deformation behaviour were observed. Samples containing NaCl particles deformed in a shear-band dominated mode, whilst the ductile foam underwent layer-by-layer deformation. © 2019 Elsevier B.V. | Elsevier Ltd | 9258388 | |

In this study, thymol was evaluated for its potential cytotoxic activity as well as its effect on apoptotic gene expression in breast cancer cell line. We used the GC-MS technique to identify the essential oil constituents of ajowan. MCF-7 cells were treated by various concentrations of thymol and half maximum inhibitory concentration (IC50) was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. In addition, morphological alterations and changes of P21, P53 and Mcl-1 gene expression in MCF-7 cells were investigated by microscopic examination and real-time RT-PCR assay. Data from MTT assay indicated that the IC50 values of thymol on MCF-7 cells for 48 h and 72 h were 54 and 62 μg/mL, respectively. Furthermore, this compound significantly affected gene expressions of P53 and P21, but not Mcl-1. Thymol can induce the apoptosis process in MCF-7, and hence it can be considered an anticancer agent in the future. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. | Springer New York LLC | 0091150X | |

The development of hydroxyapatite is due to their crystallographic and chemical similarity to the hard tissue of human body. The present study aims to prepare hydroxyapatite from a bio-waste material (carp fish bone) as an eco-friendly and inexpensive source by calcination treatment. The calcination process was applied at various calcining temperatures; the heating rate was kept constant at 10 °C min−1. FTIR results proved the formation of hydroxyapatite at 950 °C due to the founding peaks corresponding to phosphate (632 cm−1) and hydroxyl (3572 cm−1). XRD analysis confirmed the formation of HAp at 950 °C by the presence three main peaks: (211), (112), and (300), which correspond to the characteristic peaks of hydroxyapatite. Raman analyses which displayed the calcining process remove organic components from a bones matrix. AFM showed that the size of particles is ranged between nano and microns. EDS analysis found that the Ca/P reaches 1.6589 for fish bone after calcination at 950 °C, which is close to stoichiometric HAp (1.67). © 2019, Springer Nature Switzerland AG. | Springer Nature | 25233971 | |

Numerous oil spills have been documented recently in many sites due to damage in the oil industry infrastructures, which have led to soil contamination causing serious environmental hazards and deterioration to the soil and its engineering properties. So, it is essential to investigate the impact of oil leakage through the soil stratum consequently, assessing the eligibility of the contaminated soil for construction projects or identifying the appropriate treatment method. The paper investigates the general behaviour and the associated variations in the geotechnical properties upon contamination of soil in Thi-Qar Governorate which is characterised by many oil refineries. Disturbed soil samples are artificially contaminated with crude oil ranging from 0% to 10% of their dry weight. Testing programs have been conducted on the soil incorporated with conventional tests such as grading, Atterberg limit, compaction and consolidation tests as well as electrical resistivity measurements. To achieve a reliable assessment, the findings are directly compared to those of the uncontaminated soil. The final outcomes of this study indicate that an increase in oil content causes the distribution of the aggregate size curves to shift from fine to coarse ranges. Also, liquid limit, plastic limit, and plasticity index increased markedly upon contamination. Moreover, oil added to the soil mixture caused an increase in the maximum dry density of the soil and a decrease in the corresponding optimum moisture content. In addition, the consolidation characteristics of the polluted soil have been affected slightly and the electrical resistivity data was sensitive to the amount of pollutant. © 2019 Praise Worthy Prize S.r.l. | Praise Worthy Prize S.r.l | 20369913 | |

The main problem with these systems is how to maintain the privacy of sensitive patient information. Due to not fully protecting the records from unauthorised users, EHR systems fail to provide privacy for protected health information. Weak security measures also allow authorised users to exceed their specific privileges to access medical records. Thus, some of the systems are not a trustworthy source and are undesirable for patients and healthcare providers. Therefore, an authorisation system that provides privacy when accessing patients’ data is required to address these security issues. Specifically, security and privacy precautions should be raised for specific categories of users, doctor advisors, physician researchers, emergency doctors, and patients’ relatives. Presently, these users can break into the electronic systems and even violate patients’ privacy because of the privileges granted to them or the inadequate security and privacy mechanisms of these systems. To address the security and privacy problems associated with specific users, we develop the Pseudonymization and Anonymization with the XACML (PAX) modular system, which depends on client and server applications. It provides a security solution to the privacy issues and the problem of safe-access decisions for patients’ data in the EHR. The results of theoretical and experimental security analysis prove that PAX provides security features in preserving the privacy of healthcare users and is safe against known attacks. © 2019 by the authors.

The optoelectronic properties of the MPs with polycyclic aromatic hydrocarbons (PAHs) units have been investigated by using density functional theory (DFT) and time-dependent (TDDFT) at B3LYP and the 6-31G(d) basis set. These properties include total energies, Fermi energy, work function, orbital distributions (HOMO, LUMO), the HOMO-LUMO gap, the maximum open circuit voltage, maximum wavelength absorption, electronic transition energies, and the oscillator strengths. These methods and calculation procedures not only encourage a profound understanding of the association between the optoelectronic properties and chemical structures of the molecules but also can be utilized to design new molecule structures. We investigated the influence of the PAHs into the MPs and studied the optoelectronic properties on all molecules. The results showed that the maximum absorption wavelengths for MPs-PAHs are within the visible light region. Therefore, these molecules provide good performance for the photovoltaic devices and solar cells applications. Significance: Our results showed that the total energy increase after addition of PAHs for MPs, this illustration that the molecules converted to more stability. The addition of PAHs can enhance HOMO, LUMO level which can upsurge reduce bandgap energy and also the faculty of electron injection. Where the bandgap energy lies in the range (2.242–3.012) eV. The λmax takes the values from 378.84 nm to 681.03 nm, where the lowest value for Ms. (S3) and highest for the Ms. (S1), where Ms. (S1) represents firsa t singlet excited state that is at about 681.03 nm but with a feeble absorption.

The pristine BGNTs displayed wide-band gap semiconducting properties. The effect of the bilayer spacing was studied by varying the distance between the flakes from 4 Å to 8 Å which showed an increase in the band gap value from 3.33 eV to 3.46 eV, respectively. By adding N, B and BN atoms at the center between the bilayer, the band gap of the BGNFs was narrowed to 0.09 eV −1.9 eV. The aforementioned findings clearly reveal that the spacing between the bilayer along with the doping types changes significantly the induced band gap. The total energy and dipole moment were also shown to be affected by the spacing between the layers. In particular, total energy was decreased as the spacing between layers increased while the dipole moment was increased by increasing the distance between BGNFs layers comparing with pristine cases. The capability of manipulating the electronic properties of the BGNFs via changing bilayer spacing and doping atoms open up the opportunity of tuning the band gap as needed for many applications including a solar cell, photo, and gas sensor as well as energy storage nanodevices. © 2019 Elsevier Ltd | Academic Press | 7496036 | |

Objectives: The purpose of the study are 1. formulate an idea about the number of patients with bladder cancer (TCCs) in sample of Iraqi population. 2. Study the histopathological features of TCCs of bladder 3. Assessment the prevalence of (TCC) of bladder in both sex (male and female) with smoking as risk factor. Patients and Methods: A study was conducted at one institution were identified that teaching-hospital of Baghdad. All patients included in the present study diagnostic with TCC of bladder. The total of subjects participated in the study were 42 patients and 20 subjects as control through six months’ period from July 2014 to January 2015. Results: The mean of participates age was 655.7 years and the youngest was 21years and the oldest was 75 years. Out of 42 patients, the most common age group was 54-64years (52.38%) with Male to female ratio was 5.2:1.32 were male 32 and 10 were females. However, the prevalence bladder cancer (TCCs) was higher in male than in female, with more pronounced decreases in younger age (≤31year) 3(7.14), have been found. In addition, age specific rate was observed higher in the older age groups for most patients with cancer. The population attributable risk for ever smoking in our study was 33(78.57) out of 42 patients. Moreover, current study shows there was a correlation between grade and stage of bladder TCC, 24(57.14%) bladder TCCs that classified as grade I, while 2(4.76%) of bladder TCC were classified as grade II. Conversely, of the bladder TCC lesions (11.9%, 14.28%, 57.14 and 4.76) were stage (pTa-T1-T2-T3) respectively. Although this study showed 5(11.9) little-known stage and grade. The area of histopathological changes included were showed hyperplastic changes, involving the entire bladder lining, that ranged from flat hyperplasia to small areas of nodular and papillary hyperplasia. The smallest recognizable nodular and papillary lesions were associated with angiogenesis in the contiguous stroma. In addition, there were chromatin irregularities and nucleoli of variable numbers, shape and size. Nuclear chromatin irregularity and mitoses were easily identified, these cells continued to have the appearance of hyperplastic epithelium. The changes noted by generalized and orderly proliferative reaction and appeared reparative. Conclusions: Our study has revealed that the bladder TCC, where appeared the high prevalence and incidence rate of TCC of bladder in sample of Iraqi population were of concern, especially for older age groups. © 2019, International Journal of Pharmaceutical Quality Assurance.

The research study was directed at Al-Hussein Teaching Hospital in Thi-Qar Biochemistry Laboratory in College of Sciences, University of Thi-Qar, Iraq. Total 85 subjects were incorporated in this study with 50 control subjects and 35 hypertensive patients. Serum lipid profile comprising triglyceride, VLDL, antherogenic index, LDL, urea, creatinine and HDL were estimated for both groups.The results indicated the considerably higher levels of very low density lipoproteins, atherogenic index, low density lipoprotein, creatinine, triglycerides, urea and total cholesterol in patients than that of control group. Whereas, high density lipoproteins level was found to be low in patient group comparing to control. The outcome acquired from our present study concluded that a positive association of serum lipid profile particularly triglycerides, LDL and total cholesterol levels to hypertension. These advanced lipid levels might be because of stress, alcohol consumption, physical inactivity, high consumption of dietary fat and increased age.Thus, an appropriate valuation of lipid profile in all hypertensive cases is essential to halt additional intensification and coronary artery disease risks. Hence, the serum creatinine and urea level could be utilized for diabetic, hypertensive nephropathic cases and renal disease. © 2019, Advanced Scientific Research.

The geometric, energetic, and electronic properties, which include the bond length, charge, adsorption energies, HOMO energies, Fermi level energies, LUMO energies, energy gaps, work functions, dipole moments and reactivity descriptors were calculated by DFT/B3LYP with 6-31G(d) basis set for the GNR in free mode and interacted with the tyrosine (Tyr) molecule. The molecular electrostatic potential and the electron density surfaces have been constructed. Moreover, we used orbital analysis counting the density of states (DOS) to finding out the possible orbital hybridization of these hybrid structures. Based on the results, it was found that GNR shows high reactivity toward Tyr, and, in the favorable state, the calculated adsorption energy is about 2.610 eV. It is shown that the electronic properties of GNR are strongly sensitive to the presence of Tyr molecule. Therefore, we believe that these hybrid structures of nanobiosensors are able to sense the smallest amino acid constructing block of proteins, and the GNRs have the potential to be used in sensor devices. © 2019, Pleiades Publishing, Ltd. | Pleiades Publishing | 360244 | |

Two QAM modulators were implemented i.e. 4QAM and 16 QAM. The targeted board for the implementation is ZYBO board from XILINX and the used software is XILINX Vivado. The main important point in the paper is the use of quarter wave instead of full wave sinusoidal signal to generate the carrier signal. This process has saved the utilization resources by more than 50%. Saving this many resources will make a great impact on the future implantation of digital modulators since the implementation depends heavily on how the carrier signal got generated because it consumes most of utilization recourses. The paper used very high speed integrated circuit hardware descriptive language (VHDL) without the help of high level simulation tools like DSP builder tools or XILINX system generator. © 2006-2019 Asian Research Publishing Network (ARPN). | Asian Research Publishing Network | 18196608 | |

Their members include zoonotic viruses with pandemic potential where therapeutic options are currently limited. Despite this diversity CoVs share some common features including the production, in infected cells, of elaborate membrane structures. Membranes represent both an obstacle and aid to CoV replication - and in consequence - virus-encoded structural and nonstructural proteins have membrane-binding properties. The structural proteins encounter cellular membranes at both entry and exit of the virus while the nonstructural proteins reorganize cellular membranes to benefit virus replication. Here, the role of each protein in membrane binding is described to provide a comprehensive picture of their role in the CoV replication cycle. © 2019 2019 Ian M Jones. | Future Medicine Ltd. | 17460794 | |

Finite-element-method-based numerical simulations and experimental measurements were performed to quantify the size, shape, and depth of the delaminations. Two composite plates with purpose-built delaminations of different sizes and depths were analyzed. In the experiments, ultrasonic C-scan was applied to visualize the simulated delaminations. In this methodology, piezoelectric wafer active sensors were used for the high-frequency excitation with a linear sine wave chirp from 1 to 500 kHz and a scanning laser Doppler vibrometer was used to measure the local vibration response of the composite plates. The local defect resonance frequencies of delaminations were determined from scanning laser Doppler vibrometer measurements and the corresponding operational vibration shapes were measured and utilized to quantify the delaminations. Harmonic analysis of local finite element model at the local defect resonance frequencies demonstrated that the strong vibrations only occurred in the delamination region. It is shown that the effect of delamination depth on the detectability of the delamination was more significant than the size of the delamination. The experimental and finite element modeling results demonstrate a good capability for the assessment of delamination with different sizes and depths in composite structures. © 2019 by the authors.

It is observed that GNFs structure in a pure state exhibiting semiconductor behavior with big bandgap. Depending on structural properties of Li impurity in GNFs structure, the electronic properties at the ground and low-lying excited states of the structures may vary. As a result of calculations, it has been determined that Li impurity affects the bandgap values of GNFs structure significantly. The results show that the electronic properties of GNFs depend on the geometrical pattern of Li impurity in the GNFs structure. The bandgap of GNFs is hardly red-shifted by the doping of Li impurity due to the interaction with the sp-hybrid orbital. The effects of Li impurity both the ground and excited electronic states of GNFs were discussed. In addition, we can provide bandgap tuning of GNFs by doping Li as required, and for its application in solar cell and nanoelectronic devices. © 2019 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

Our results show that the electronic and electrical properties can be controlled using (0% to −10%) strain. The behavior of g-SiC3 is altered from a semi metallic to semiconductor. The electronic band gap is opened under −9% and −10% strain. Also, the geometry of g-SiC3 is altered under with these two percentages of strain due to the bond length between C-Si atoms is increasing. The electrical conductivity of siligraphene g-SiC3 as a function temperature without and with strain has been given. We detected very exciting results. It is affected and changed when at the same percentage of strain, which applied to alter the behavior of g-SiC3 to semiconductor. Then, these properties can be led to generate new 2-D nanomaterials and devices with huge control over their physical properties for a wide range of applications ranging from photovoltaic to photo-catalysis. We show that siligraphene is a very promising 2D material with great impact that can lead to exceptional results in the field of solar energy and other application.

CFRP can greatly improve the flexural and shear capacity of deteriorated members and therefore extends their useful life. The main problem of external CFRP is the debonding of the sheets from the concrete surface at some point of loading, which negatively affects the efficiency of strengthening and may consequently lead to an unanticipated failure of the strengthened members. The major reason for this early debonding is likely due to the low accuracy of the preparation and the high stress concentration at the flat contact area exists between CFRP sheets and the concrete. The problem has been extensively discussed in the literature and some CFRP application techniques such as “Externally Bonded Reinforcement on Grooves (EBROG)” and “Externally Bonded Reinforcement in Grooves (EBRIG)” have been proposed as alternatives to the conventional application methods. Although some research has been carried out, there have been few experimental investigations that provided quantitative discussion of the efficiency of the new developed techniques. This research was aimed to experimentally assess the efficiency of grooving techniques and to provide a quantitative data regarding the behaviour of bonding between CFRP and concrete. The effects of shape and direction of the grooves and CFRP layers on the load carrying capacity, mid-span deflection and failure mode of thirteen RC beams have been investigated and discussed. In general, CFRP has significantly improved the flexural capacity of strengthened beams especially when grooving technique has been employed. © 2019, Brazilian Association of Computational Mechanics.

Recently, various machine learning techniques have been developed to tackle the problems of IPS. The WLAN fingerprinting technique is one of the most cost effective choices for IPS due to the use of existing Wi-Fi networks in commercial and public buildings. However, the variation of Received Signal Strength (RSS) at any specific location due to the indoor fading issue leads to serious challenges in the accuracy of the distance estimates. In this paper, we propose a new technique by using Probabilistic Neural Network (PNN) multi-classifier based on Multiple Service Set Identifiers (MSSIDs) that are configured on the same access point. A spatial voting scenario for three PNN-classifiers is proposed as a tool to determine the location of the user. Using a spatial voting based technique is specifically designed to tackle the negative impact of the multi-path propagation on the performance of IPS. The proposed system is performed inside the College of Engineering and Applied Sciences (CEAS) at Western Michigan University. The performance of the proposed system compared with some of the common methods such as K-Nearest Neighbors (K-NN) and multi-class support vector machine (SVM). According to the experimental results, the spatial voting of the three PNN-dassifiers can significantly mitigate the adverse effects of RSS variation. The performance of the multi-classifier exhibits superior performance to that of the other single classifiers in all Area of Interest (AOI). Over 3000 m2 AOI, the proposed system achieves localization accuracy < 0.73m and with precision 90 % of the distance error less than 2m. © 2019 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Urinary tract infection (UTI) in pregnant women is especially important because it may produce complications that may be serious to the mother and fetus. Seventy-five samples were collected aseptically in sterile disposable containers. The microscopic examination of the urine plays an important role in the diagnosis of UTI based on the presence or none of pus cell, crystals, Epithelium cell and RBCs, as well as the appearance of the bacteria in the urine sediment under the microscope in large numbers confirming its presence in the urine. However, the culture remains the basic rule in diagnosing urinary tract infections. The specimens were labeled and transported to the microbiology laboratory. A calibrated sterile platinum wire loop was used to transfer 1μl of the uncentrifuged urine specimen and streaked on MacConkey agar and EMB agar during the period from November 2017 to February 2018. The DNA was extracted from E. coli and the PCR technique 16srRNA gene was detected by the specific primers. Using electrophoresis after adding red safe stain, the bands size appeared 1250 base pairs, then the samples are sent to conduct the sequencing. The results showed three variations: two Transition and once Transversion. The results of phylogenetic analysis showed proximity and the genetic dimension among themselves and the world with more than 99% compatibility values. © 2019, World Research Association.

It is good to communicate between the dumb and other people by convert dumb sings into voice, where that voice is clear for all people they cannot understand the gesture. In this paper, we suggest an algorithm for recognizing hand gestures of Arabic numbers (0-10) to using by dumb (through signs) and converting the sings into voices corresponding to sings numbers. The algorithm uses video for gesture of the dumb then converts this video into frames (images), Preprocessing for the resulted image must be done by removing the noise, resize the images and increasing the contrast, then calculating the distance to clustering the numbers by using C4.5, k-mean, k-medoid and artificial neural network. Eighteen features are calculated; eight features from Euclidean distance, eight features from slop, Area, and perimeter. The results in the training stage were the accuracy are; C4.5 gave 100%, k-mean gave 90.2357% k-medoid gave 87.5421% and artificial neural network gave 82.3793%.

Herein, graphene nanosheets (GNS) were firstly synthesized through liquid phase exfoliation (LPE) of graphite in isopropanol then mixed with epoxy resin (ER) creating a composite of GNS/ER. The properties of the as-obtained structure were evaluated by transmission electron and ultraviolet–visible spectroscopies. The nonlinear optical properties (NLO) of GNS/ER were investigated through single beam Z-scan technique using a continuous-wave (CW) laser beam obtained from a solid-state laser (SDL). The results reveal that GNS/ER composite shows a negative nonlinear refractive index of (−0.26 × 10−8 cm2/W). Optical limiting (OL) measurements were performed on the GNS/ER and the mechanism of the OL is ascribed to the nonlinear refraction (thermal effects). These outcomes specify the potential use of cost-effective produced GNS/ER composite to boost the NLO and OL for future photonic applications. © 2019 Elsevier B.V. | Elsevier B.V. | 9253467 | |

A hybrid global–local approach was used in conjunction with the imaging methods for the numerical simulation. The hybrid global–local approach allowed fast and efficient prediction of scattering wave signals for Lamb wave interaction with crack from various incident directions. The simulation results showed the directionality effect of the scattering wave signals and suggested an optimum transmitter–sensor configuration. Two imaging methods were used: one involves the synthetic time reversal concept and the other involves Gaussian distribution function. Both imaging methods show very good agreement during simulations. Experiments were designed and conducted based on the simulated results. A network of eight piezoelectric wafer active sensors was used to capture the scattering waves from the crack. Both the pitch-catch and pulse-echo experimental modes were used. The directionality effect of incident Lamb waves on the imaging results was studied. The effect of summation, multiplication, and combined algorithms for each imaging method was studied. It was found that both methods can successfully predict the crack size and orientation. An attempt was made to use these imaging methods for detecting and sizing smaller sized damage (1- to 3-mm-diameter hole). It was found that these methods can successfully localize the hole, but size estimation was a bit challenging because of the smaller dimensions. The scattering waves for various hole sizes were studied. © The Author(s) 2018. | SAGE Publications Ltd | 1045389X | |

Specifically, we study enabling friendly coexistence mainly by interference reduction through increase in the power transmission cost on each LTE AP 1 (eNodeB) and WiFi AP and find the conditions under which a long-term coexistence can be established. We model this long-term coexistence by finding the evolutionary stable strategies of the evolutionary game. We analyze the cost functions for the LTE-U and the WiFi APs, and show that the LTE-U AP behavior is more sensitive to the cost than to the number of users, while WiFi is more sensitive to the number of users than to the transmission power cost. To further reduce the interference, we consider the case where the WiFi AP removes users that cannot establish the minimum signal to interference plus noise ratio required to reduce the interference to the LTE-U AP users. Interestingly this creates more interference due to the aggressive/selfish behavior of the WiFi APs. Finally, we extend the game over continuous strategies by formulating a game theoretic model for the coexistence problem, find its Nash equilibrium, and study its stability under the replicator dynamics of the evolutionary game. 1 For simplicity, we use the term AP to also refer to LTE-U eNodeBs. © 2015 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 23327731 | |

Peripheral and central aeration were applied to study the effectiveness of oxygen dissolution and the pump-turbine performance. The peripheral draft tube aeration was performed by air injection through (1) a continuous orifice and (2) a series of discrete orifices along the surface of the draft tube. The simulations were performed when the system is operating in the turbine mode. Peripheral aeration was more effective for the achieved dissolved oxygen level and the oxygen dissolution efficiency. The mean dissolved oxygen concentration and the dissolution efficiency inside the draft tube were predicted to be 1.8 mg/l and 80% using the continuous or discrete peripheral aeration and 1.4 mg/l and 25% using the central aeration. A mean value ranging from 1.0 mg/l to 2.0 mg/l was considered to be sufficient for aerobic bacteria to treat the wastewater. Aeration resulted in a minor penalty on the power generation, while it provided a significant reduction in the flow-induced vibration. The central aeration was more effective in reducing the amplitude of pressure fluctuations and yielded more stable turbine operating conditions. © 2018 Elsevier Ltd | Elsevier Ltd | 179310 | |

Overall, 192 men, recruited from two University Hospitals, were allocated into two equal groups of matched age; healthy potent men and men with ED non-responders for oral sildenafil citrate. Oral sildenafil citrate non-responders self-reported inadequate erectile responses after four attempts using 100 mg with the manufacturer’s guidelines relative to meals, associated medications, and sexual stimulation/arousal. Exclusion criteria were: diabetes, cardiovascular disorders, beta blockers treatment, morbid obesity, thyroid disorders, post-radical prostatectomy, and hepatic/renal failure. All participants were subjected to; history taking, clinical examination, validated IIEF-5 questionnaire, estimation of serum l-carnitine by calorimetric method and serum 25(OH)D by ELISA method. Compared with potent controls, ED men non-responders for oral sildenafil citrate showed significant decreases in the mean serum l-carnitine level (16.8 ± 3.6 uM/L versus 66.3 ± 11.9 uM/L, P = 0.001), the mean serum 25(OH)D level (21.2 ± 7.1 ng/ml versus 54.6 ± 7.9 ng/mL, P = 0.001) and IIEF-5 score (7.8 ± 2.6 versus 23.9 ± 1.3). Serum l-carnitine showed significant positive correlation with IIEF-5 scores (r = 0.873, P = 001), serum 25(OH)D (r = 0.796, P = 0.001) and significant negative correlation with the age (r = -0.515, P = 0.001). Serum 25(OH)D showed significant positive correlation with IIEF-5 scores (r = 0.855, P = 0.001) and significant negative correlation with the age (r = -0.223, P = 0.005). It is concluded that normal homeostasis of serum l-carnitine and 25(OH)D play a role in male sexual health being significantly decreased in ED non-responding for oral sildenafil citrate. © 2018, Macmillan Publishers Limited, part of Springer Nature. | Nature Publishing Group | 9559930 | |

The model was developed using a database collected from 207 experiments available in the existing literature. Five key input parameters were used to build the model, which were slab effective depth, concrete strength, reinforcement ratio, yield tensile strength of reinforcement, and width of square loaded area. The output parameter of the model was punching shear strength. The results from the adaptive neural fuzzy inference model were compared to those from the simplified punching shear equations of ACI, BS-8110, Model Code 2010, Euro-Code 2, and also experimental results. The root mean square error (RMSE) and the correlation coefficient (R) were used as evaluation criteria. Parametric studies were presented using ANFIS to assess the effect of each input parameter on the punching shear strength and to compare ANFIS results to those from the equations proposed in commonly used codes. The results showed that the ANFIS model is simple and provided the most accurate predictions of the punching shear strength of two-way flat concrete slabs without shear reinforcement. © 2019 by the authors. | MDPI AG | 20763417 | |

The flow is uniform and parallel to the moving flat plate, and both flat plate and flow are moving on the same directions. The investigated parameters in this study are power-law index, permeability parameter, Eckert number, volume fraction of nanoparticles, nanoparticles type, velocity ratio and heat absorption/generation parameter. The nanoparticles used in this paper are Al 2 O 3 , TiO 2 , Cu and CuO dispersed in sodium carboxymethyl cellulose/water as the base fluid. By using suitable transformations, the governing partial differential equations are converted into the ordinary differential equations, and after that, the resulting ODEs are solved with Runge–Kutta-Fehlberg fourth–fifth-order numerical method. The results of this investigation showed that heat transfer of Newtonian and non-Newtonian nanofluids in the presence of viscous dissipation and generation/absorption of heat has an interesting behavior: For Newtonian fluid, by increasing the amounts of high-conductive nanoparticles to carrying fluid, a higher heat transfer is not obtained. For instance, copper nanoparticles, despite having highest thermal conductivity compared to other nanoparticles, show the lowest local Nusselt number. However, for pseudo-plastic non-Newtonian nanofluids the observed trend was reversed. Furthermore, in both Newtonian and non-Newtonian nanofluids, the local Nusselt number decreased, by increasing injection parameter, heat generation or volume fraction of nanoparticles (in high Eckert numbers). That is while, by enhancing the heat absorption, velocity ratio, suction parameter or volume fraction of nanoparticles (in low Eckert number), the local Nusselt number augments. © 2018, Akadémiai Kiadó, Budapest, Hungary. | Springer Netherlands | 13886150 | |

These compounds affect the growth and development of microorganisms and plants, and seriously harm the health of animals and humans. Some of these compounds may disrupt the normal function of the central nervous system, cause changes in the blood content, and adversely affect the function of lungs, kidneys, liver, and other organs. The long-termaction of chemical compounds may cause the development of cancer, allergy, dystrophy, physical and neurological degenerative processes, Alzheimer's, and Parkinson's. At the same time, fertilizers, pesticides, and sewage from industrial plants contaminate soil and water. Many physicochemical methods of treating chemical compounds of wastewater are available, but these methods are constrained because of their limited versatility, high cost, low efficiency, and interference from another wastewater constituent. These physicochemical methods also produce large quantities of sludge, posing a threat as a secondary pollutant. However, biological methods are available that are eco-friendly and completely mineralize organic pollutants. These methods have a wide range of applications, low running costs, effect complete mineralization of chemical compounds to nontoxic compounds, and are eco-friendly. They are dependent on microorganisms used in aerobic and anaerobic conditions, such as bacteria and fungi, algae, and other organisms present in the environment, and phytoremediation is a technology that should be considered for the remediation of contaminated sites because of its cost effectiveness, aesthetic advantages, and long-term applicability. This technology can be applied to metal pollutants that are amenable to phytostabilization, phytoextraction, phytotransformation, rhizosphere bioremediation, or phytoextraction. © Springer Nature Switzerland AG 2019.

The solution represented by a nonlinear flow-based model of fast rerouting with the protection of such two network performance indicators as bandwidth and probability of packet loss is proposed. This model at the level of the flow conservation conditions takes into account the buffer limitedness of queues on the routers interfaces, which allowed controlling the probable overload of the link resource. The numerical example confirmed the adequacy of the offered model and the efficiency of the decisions made in relation to the fast rerouting of data traffic with the realization of the protection scheme for bandwidth and probability of packet loss. © 2019 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Hereby, the LSD-4 codes are produced via generating 224 codewords of 15 bits length. The LSD-4 codes length is extremely long (equal to 4096 bits); accordingly, the encoding/decoding by the LSD-4 codes becomes more compatible with optical speed and consistency. Apparently, increasing the length of coding is concurrent with the ODF speed. Our model is grounded on hiring the LSD-4 codes in the encoding/decoding process of the onboard ODF for optical routing serial. The net gain of plugging the planned LSD-4 codes in optical routing is obtained within 5- to 15-dB range for diverse optical routing forms at code length 4096 bits with Q-ary pulse-position modulation. The numeric and simulated results confirmed the significant improvements of the planned LSD-4 codes performance with ODF over the non-LSD-4 codes ODF counterparts. © 2019 Society of Photo-Optical Instrumentation Engineers (SPIE). | SPIE | 913286 | |

Since the spontaneous emission effect is an important factor in a microcavity the rate equations model has been reconsidered to include the Purcell spontaneous emission enhancement factor F and the spontaneous emission factor. It is found that the synchronization takes place under suitable system parameters. The results indicate that the coupling strength, the delay time in the transmitter, and the transmission time between the two lasers have significant effects on the synchronization quality while the stage number and the delay time in receiver have poor effects on the synchronization quality. Also, when the system is a closed-loop or open-loop, synchronization with poor dynamics occurs when the spontaneous emission factor is small while the synchronization happens in the open-loop system only when the spontaneous emission factor is large. Furthermore, when the system is a closed-loop, synchronization occurs when Purcell factor is large while the synchronization happens to the open-loop system of any values for the spontaneous emission factor and Purcell factor.

Developing an effective method to identify these transitions in sleep electroencephalogram (EEG) recordings is an ongoing challenge, as there are typically hundreds of such transitions in each recording. This paper proposes a statistical model and a method based on wavelet Fourier analysis to detect sleep spindles. In this work, spindle detection is achieved in two phases: a training phase and a testing phase. An EEG signal is first divided into segments, using a sliding window technique. The size of the window is 0.5 s, with an overlap of 0.4 s. Then, each EEG segment is decomposed using a discrete wavelet transform into different levels of decompositions. The wavelet detail coefficient at level 3 (D3) is selected from these parameters, and this is passed through a fast Fourier transform to identify the desired frequency bands {α β θ δ γ}. Ten statistical characteristics are extracted from each band. Nonparametric Kruskal-Wallis one-way analysis of variance is used to select the important features, representing each of the 0.5 s EEG segments. To detect all possible occurrences of sleep spindles in the original EEG signals, four different window sizes of 0.25, 1.0, 1.5 and 2.0 s are also tested. Finally, the extracted features are used as the input to four classifiers to detect the sleep spindles: a least-squares support vector machine (LS-SVM), K-nearest neighbours, a K-means algorithm and a C4.5 decision tree. The obtained results demonstrate that the proposed method yields optimal results with a window size of 0.5 s. The maximum averages of accuracy, sensitivity and specificity are 97.9%, 98.5% and 97.8%, respectively. This method can efficiently detect spindles in EEG signals, and can assist sleep experts in analysing EEG signals. © 2018 Elsevier Ltd | Elsevier Ltd | 17468094 | |

The qcs have been measured through performing the Cone Penetration Tests (CPTs) on soil at four locations in the site of water intake project in Nasiriyah, Iraq as part of a soil site investigation program. The suggested applied vertical loads were 50–550 kPa. The qcs below the foundation level were considered uncertain and were simulated as random variables. Different probability distributions (PDs) were used to simulate the qcs values: normal, logistic, lognormal, Gamma, Weibull, Inverse Gaussian and Rayleigh distributions. Choosing the appropriate distribution was based on a goodness of fit (GOF) test. Monte Carlo simulation (MCS) was used to model the limit state function (LSF) based on a direct solution. It was found that the bearing capacity is sensitive to both the coefficient of variation of qcs and applied vertical load. It also was found that different PDs for soil parameters may result in the different PD of BC. Varying the width of shallow foundations changes the values of qcs and their probability distributions. According to this change, the reliability index of BC is slightly affected by the width of the foundation. The reliability index shows a good value at stress 100 kN/m2 higher than the target reliability and the reliability equal to zero at 550 kN/m2. A nonlinear behavior was observed between the probability of bearing capacity failure and the coefficient of variation of the applied vertical load. © 2018 | Elsevier B.V. | 22150986 | |

The implementation of a two-level hierarchy of calculations is proposed on the SDN controllers with multicore architecture where the lower level is responsible for calculating the routing variables, and the upper level is for solutions obtained from the lower level coordination. In proposed multicore architecture of SDN controller the border routers of the network will be matched by the controller core, which performs the function of calculation the routing variables. The separate core of the controller will act as a coordinator with function of link overload prevention. Application of the proposed method allows to increase the scalability of routing solutions, reduce the amount of service information that circulates in the network, as well as reduce the complexity of the whole method. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The proposed method consists of four main steps. Firstly, in order to investigate which method is most suitable to decompose the EEG signals into frequency bands, we implement separately a fast Fourier transform (FFT) or discrete wavelet transform (DWT). Secondly, each band is partitioned into k windows and a set of statistical features are extracted from each window. Thirdly, the InfoGain is used to rank the extracted features and the most important ones are selected. Lastly, these features are forwarded to a least square support vector machine (LS-SVM) classifier to classify the EEG. This scheme is implemented and tested on a benchmark EEG database and also compared with other existing methods, based on some performance evaluation measures. The experimental results show that the proposed FFT combined with InfoGain method can generate better performance than the DWT method. This method achieves 100% accuracy for five different pairs: healthy people with eyes open (z) versus epileptic patients with activity seizures (s); healthy people with eyes closed (o) versus s; epileptic patients with free seizures (n) versus s; patients with free seizures epileptic (f) versus s; and z versus o. The accuracies obtained for two other pairs, (o vs. n) and (z vs. f), are 95.62 and 88.32%, respectively. These two pairs have more similarities with each other, leading to a lower level of accuracy. The proposed approach outperforms six other reported methods and achieves an 11.9% improvement. Finally, it can be concluded that the proposed FFT combined with InfoGain method has the capacity to detect epileptic seizures in EEG most effectively. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature. | Springer Verlag | 14327643 | |

Characteristics of EEG signals are complex, being non-stationarity, aperiodic and nonlinear in nature. EEG signals are a combination of sustained oscillation and non-oscillation transients that are challenging to deal with using linear approaches. Method: This research proposes a new scheme based on a tunable Q-factor wavelet transform (TQWT) and a statistical approach to analyse various EEG recordings. Firstly, the proposed method decompose EEG signals into different sub-bands using the TQWT method, which is parameterized by its Q-factor and redundancy. This method depends on the resonance of a signal, instead of frequency or scaling as in the Fourier and wavelet transforms. Secondly, using a statistical feature extraction on the sub-bands to divide each sub-band into n windows, and then extract several statistical features from each window. Finally, the extracted features are forwarded to a bagging tree (BT), k nearest neighbor (k-NN), and support vector machine (SVM) as classifiers to evaluate the performance of the proposed feature extraction technique. Results: The proposed method is tested on two different EEG databases: Bonn University database and Born University database. The experimental results demonstrate that the proposed feature extraction algorithm with thek-NN classifier produces the best performance compared with the other two classifiers. Comparison with existing methods: In order to further evaluate the performances, the proposed scheme is compared with the other existing methods in terms of accuracy. The results prove that the proposed TQWT based feature extraction method has great potential to extract discriminative information from brain signals. Conclusion: The outcomes of the proposed technique can assist doctors and other health experts to identify diversified EEG categories. © 2018 Elsevier B.V. | Elsevier B.V. | 1650270 | |

The controlling parameters that are examined are four coherent optical fields, three tunneling components, and incoherent optical pumping. This work differs from others by the inclusion of a wetting layer (WL) and the calculation of momenta for each transition. The results showed that the entropy depends on the difference between the carrier occupations in the states of these two quantum dots (QDs). It is also shown that the probe optical field reduces the entropy, while the pumping field increases it. Turning off the main tunneling component removes the entropy, while high WL–QD momentum increases the entropy. Taking the same value of momentum for all transitions (the case of other works) underestimates the entropy. © 2019 Optical Society of America. | OSA - The Optical Society | 1559128X | |

First, the characterization of the PWAS materials shows that no significant change in the microstructure after exposure to high temperature and nuclear radiation, and the PWAS transducer can be used in harsh environments for structural health monitoring (SHM) applications. Next, PWAS active sensing of various damage types in aluminum and composite structures are explored. PWAS transducers can successfully detect the simulated crack and corrosion damage in aluminum plates through the wavefield analysis, and the simulated delamination damage in composite plates through the damage imaging method. Finally, the novel use of PWAS transducers as acoustic emission (AE) sensors for in situ AE detection during fatigue crack growth is presented. The time of arrival of AE signals at multiple PWAS transducers confirms that the AE signals are originating from the crack, and that the amplitude decay due to geometric spreading is observed. © 2019 by the authors.

Moreover, the present paper examines the positive roles of glucose and lipid on the correction of oxidative stress diabetes-related complications in alloxan diabetic rats. To acheive the objective of study, 24 of female rats ((Rattus norvegicus) have been used. The division of animals was done in 4 groups (6 each). Diabetes was enhanced by injected intraperitoneally with alloxan at a single dose in body weight; 125 mg/kg. Diabetic rats go through a specific rise (p ≤ 0.05) in the glucose levels, triglyceride, total cholesterol, very-low-density lipoprotein, low-density lipoprotein, and malondialdehyde and an important noticeable decrease in high-density lipoprotein, glutathione, and albumin. In addition, taurine supplementation caused a significant reduction in the glucose, total cholesterol, triglycerides, low-density lipoprotein, and very low-density lipoprotein levels. The obtained results revealed that taurine exhibited an inhibitory effect on oxidative stress indices (MDA) and improved antioxidant levels. Taurine could have potential as a pharmaceutical drug for diabetes mellitus (DM), and this invites further studies in this field. © 2019, International Journal of Pharmaceutical Quality Assurance.

Understanding the biology of this tumor is a prerequisite for selecting an appropriate treatment. Cell cycle alterations are seen in many cancers such as breast cancer. Newly popular targeted agent in breast cancer are cyclin-dependent kinase inhibitors (CDKIs), which are agents inhibiting the function of cyclin-dependent kinases (CDKs) is a member of protein kinase family. It plays an important role in regulating various events of eukaryotic cell division cycle. Accumulated evidences indicated that over expression of CDKs should cause the abnormal regulation of cell-cycle, which would be directly associated with hyper proliferation in cancer cells. They are categorized as selective and non-selective inhibitors of CDK. CDKIs have been tried as monotherapy andcombination therapy. In this review, we present the structure, functions and activation of CDKs by cyclin binding with special focus on recent advances in the development of different CDKI in breast cancer. © 2019.

Specifically, the average secrecy capacity (ASC), secure outage probability (SOP), the lower bound of SOP (SOPL), and the probability of strictly positive secrecy capacity (SPSC) are derived using two different values of the fading parameters, namely, m and μ which represent the multipath and shadowing severity impacts, respectively. Firstly, when the fading parameters are arbitrary values, the performance metrics are derived in exact expressions in terms of the extended generalised bivariate Fox's H-function (EGBFHF) that has been widely implemented in the open literature. In the second case, to obtain simple mathematically tractable expressions in terms of analytic functions as well as to gain more insight on the behaviour of the physical layer security over Fluctuating Beckmann fading channel models, m and μ are assumed to be integer and even numbers, respectively. In addition, the asymptotic behaviour for all the studied performance metrics has been provided. The numerical results of this analysis are verified via Monte Carlo simulations. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

A wide range of bacterial infection correlated with progress CVD. So this search aim to detect the bacterial type in CV patients. The total number of patients that attended the Herat Medical Center Thi-qar province from April to November (2018) were 280 which were further divided in two groups. These comprised of two hundred (7.14%) patients with catheterization including 100(50%) diagnostic catheters, collective 20(10%) therapeutic and diagnostic catheters as well as 80(40%) therapeutic catheters. Moreover, it was observed to be that 2(27.5%) patients went through heart defect surgery, 30(37.5%) patients signified valve replacement surgery, 80(28.6%) symbolized (CABG) coronary artery bypass grafting surgery. The Swabs, Catheter tip and blood samples were taken from all patients and surgery instruments and Cultured on blood culture bottle for 24 h at 37C then sub-culture on enrichment and differential media. The results showed that positive bacterial culture appear in 62 (31%) cardiac catheterized patients, some of them showed polymicrobial infection up to 70 bacterial isolates out of which 138(69%) showed no growth, while G-ve bacteria are of about 15(21.4%) & G +ve are of 55(78.6%). However, surgical patients verified 18(22.5%) gram positive bacterial growth while presented more than one bacterial category. Likewise, total isolate number improved to twenty three isolates of bacteria in which 62(77.5%) represented no growth, 20(87%) showed isolates of G +ve and 3(13%) presented G-ve isolates. Both type of patients discovered major common pathogen S. aureus while following with viridans streptococcus & St. pyogenes. G-ve isolates showed that Enterobacter cloacae most common in catheterization patients and Klebsiella pneumonia in surgery patients. In conclusion: infection in CVD had a significant role in progression the disease that lead to serious morbidity and even mortality. So accurate diagnosis to bacterial infection increase the success therapy and avoid complication of disease. © 2019, Connect Journal. | Connect Journal | 9725075 | |

However, despite the dissimilarities in their nature, all construction projects are intended to be successful and profitable. A successful construction project is a project that completed within the intended time frame and budget, with acceptable quality, and no serious accidents. Successful managers lead and motivate different players of a project towards achieving the same goal and accomplish construction projects� objectives. Similar perception is the glue that holds all players collaborate and work together towards the same goals. Although the difference in perceptions is inevitable, it raises challenges that can hinder a project to succeed. Therefore, the purpose of this study was to 1) assess how construction managers perceive the relative values of safety, quality, cost, and time and 2) examine the difference between the perceptions of project managers and intermediate-level managers and workers. To fulfill the research objectives, 48 construction employees across the U.S. participated in this study. The results showed that safety has the highest relative importance in the perception of managers compared to the other factors. The findings revealed that there is a significant difference between the perception of construction project managers and superintendents concerning project cost (p-value<0.01) but not safety, quality, and time (p-value>0.1). This research can help construction professionals and practitioners to identify the difference in perceptions among key players and enhance managerial efforts to align dissimilar views towards the success of construction projects. � 2019 Canadian Society for Civil Engineering.

What factors influence the patterns found in these networks? Do social norms have any role in shaping these patterns? While construction worker interactions have been studied in many ways, network-based interactions are scarcely investigated. Additionally, the limited attempts in social network construction safety research have not used inferential aspects in studying the topic. Using these perspectives and questions as a starting point, the present study investigates the application of Exponential Random Graph Models (ERGMs) in construction safety research. In the study, an exploration of ERGMs is introduced theoretically by explaining the basics of the modelling, and practically by introducing a simple case study to enhance understanding of how ERGMs can be used. The research methods include a literature review and an analysis of observational data from the construction field. The results show that both approaches support the idea that ERGMs are a beneficial and capable tool that can be used in safety research. Additionally, the findings show that the probability of having a denser network with regard to safety risk is higher than it should be to have a safe jobsite based on the fact that the higher connectivity, the higher the possibility for a worker being injured. The contribution of this study is the introduction of a new inferential procedure for analyzing worker interactions on construction jobsites with respect to safety. � 2019 Canadian Society for Civil Engineering.

The study presented in this paper aims to investigate the interaction properties that impact safety issues on jobsites. To meet this objective, periodic observations of the work taking place on a building construction project were conducted. During the observations, tens of hours of video recordings of workers conducting their traditional jobs/tasks were taken. After the completion of the work, an analysis of the two-mode networks for the worker and design element interactions using the social network analysis method was conducted. Two design element cases were analyzed, the concrete slab and steel beam components of the structure. The analysis shows that the workers are highly connected when considering the worker-design element interaction. To some extent, this result confirms the impact of design elements on the risk level of a worker. In addition to investigating the risk results for different trades on the jobsite, this study is unique in that it is the first in construction safety research to develop and analyze two-mode networks on top of video observations. The construction community can benefit from this study by extending current knowledge of the interactions that might lead to indirect risks, and then planning the work in a way that prevents and/or controls these interactions. � 2019 Canadian Society for Civil Engineering.

The government Iraq has been seeking to apply electronic systems in government departments. Therefore, most employees' salaries have started to become electronic. However, this rapid shift from the manual processes to electronic methods has caused a number of problems. These include salary delay, hardware failure and employee fear of theft. This has led to a lack of confidence in the use of electronic transactions. Therefore, the motivation of this study is to find reasons for the problem of why some employers use electronic banking systems, while others do not. This empirical study sought to extend the technology acceptance model to determine the key factors that hamper the full application of electronic financial transaction methods in Iraq. For this purpose, the data was gathered from the employees in the Ministry of Higher Education and Scientific Research as well as Ministry of Education, who have experience in online transactions and ATMs. The findings revealed that four out of eleven hypotheses show no significant impact on e-banking services' acceptance. In summation, factors such as accessibility, usefulness, trust and ease of use will enhance electronic banking services' acceptance. © Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

Huet,1856; Hypecoum pendulum Linnaeus, 1753; Papaver fugax Poiret,1804; Papaver macrostomum Boissier & A. Huet, 1867; Papaver rhoeas Linnaeus, 1753 and Roemeria refracta de Candolle,1821. The results showed that the anticlinal cell walls of the adaxial surface were more thickened in P. fugax, H. pendulum, P. macrostomum and R.refracta, while it was thin in P. rhoeas. The current investigation finds three types of the stomata (i.e., anomocytic, paracytic and hemiparacytic), and the number of stomata on the adaxial epidermis ranged between 22.11 stomata mm2 in P. rhoeas and 69.30 stomata/mm2 in P. fugax; the stomatal index percentage on the adaxial surface was 15.04% in P. macrostomum and 4.14% in P. rhoeas. The type of the mesophyll was bifacial (dorsiventral) in structure for the species. Stems gave a good character in separation of the species; shape and size of cortex cells, and the numbers of cortex layers were taxonomically significant. The observations of this study showed six types of trichomes that were non-glandular biseriated, triseriated or multiseriated, unicellular with multicellular short hairs and finally uniseriate long hairs (in G. grandiflorum). P. rhoeas recognized by found glandular short hairs. © 2019 University of Baghdad - Iraq Natural History Reseach Center and Museum.

Oxidative stress has been a well-studied etiology of abnormal semen parameters. Reduced fertilizing capacity is related to raised concentrations of reactive oxygen species in semen, which may damage the cell membrane. Multiple over-the-counter therapies have been historically used for male fertility like (Coenzyme-Q10, and Arginine). Objectives of study: To determine the role of some of the antioxidants in the improvement of the semen parameters in a subfertile male, improvement by (coenzyme, q10 l-arginine) therapy. Method: An experimental interventional non-randomized clinical trials study for exploring the male sub-fertility improvement by (L-arginine and Co-enzyme-Q10) therapies-in Al Nasiriyah City in 2019. Sample size The study contained three groups. Each group contains eight included responders. Male-patient responders who were diagnosed to have unexplained sub-fertility by a specialist gynecologist and urologist after excluding all organic causes of the subfertility, SPSS version 24 had been used for data analysis, paired t-test, correlation regression analysis had been used, where p-value < 0.005 considered as significant. Result: A total of 24 patients with infertility, their mean age was 32 + –6.52 years, had been recruited within the study, with a very high significant statistical difference (p-value < 0.005) between the first and the second occasions of measures and also between the first and the third occasions of measures, regarding volumes, counts, number of active sperms, number of active sperms, number of sluggish sperms, number of non-active sperms and number of abnormal sperms. By correlation regression analysis, there was a significant positive correlation of the independent parameters with the types of management modalities, where crossly examined by correlation regression. It was evident that all parameters except the counts are positively correlated by which p-value < 0.05. Conclusion: This study concluded that the administration of Co-Enzyme, L-Arginine, and combination of both show improvement in most of the parameters of the semen. The combination was the first improver of the semen parameter followed by arginine, then the Co-Enzyme only, the volume, sperm morphology, and the activity were the main parameters affected by the multiple strategies of treatment protocols. Adding of the co-Enzyme to the protocol of the L-Arginine as a good semen volume incrementer, activity enhancer, abnormal morphology reducer. © 2019, International Journal of Drug Delivery Technology.

Rossin College of Engineering and Applied Science, Lehigh UniversityPA 18015, United States | Large Eddy Simulation (LES) turbulence and multiphase Volume of Fluid (VOF) model are employed to predict the spatial and temporal characteristics of the turbulent flow structures near micro-hydrokinetic turbine operating in the proximity of a free surface. The turbine power performance and the free surface dynamics, and its interaction with the turbine are characterized by examining the results of both single-phase and multiphase flow simulations. Simulations are conducted at the turbine’s best efficiency point at a tip speed ratio of 1.86 with the rotation rate of 150 rpm and the free stream water velocity of 2.25 m/s. The multiphase flow simulation is carried out at Froude number of 1.06. The results indicate slight interaction between the deformed free surface and the turbine wake structures. Acceleration in the flow velocity is observed near the free surface due to the physical confinement. The results indicate that turbine power generation is reduced by about 2.0%, and the thrust coefficient is reduced by 1.60%. It is demonstrated that the turbine performance at this Froude number is hardly influenced by the presence of the free surface.

However, some genetic variants have been linked to kidney disorders. Methods: This study involved 120 subjects (70 hemodialysis-treated patients with chronic renal failure and 50 healthy subjects as control). Serum biochemical parameters creatinine and urea were detected as diagnostic markers to renal functions. Sixty subjects (44 patients & 16 control) were genotyped for polymorphism of the enzyme gene conversion of angiotensin. The distribution of genotype and allele frequencies for angiotensin-converting enzyme-Deletion / Insertion single nucleotide polymorphisms has been evaluated in both groups. Results: The levels of biochemical parameters creatinine, and urea in renal failure patients increased significantly when compared with healthy. The angiotensin-converting enzyme genotypes distribution between subjects groups in Thi-Qar indicated that the percentage of DD genotype was found to be high in the group of 23 patients (52.3%), followed by ID 16 (36.3%) and II genotype 5 (11.4%). As, the genetic pattern in the control group showed that the genotype DD and ID patterns had the same percentage of 37.3%, followed by genotype II, 25%. Also, there is an increase of D-allele frequencies in the group of patients equivalent with healthy controls. Conclusions: The high frequency of angiotensin-converting enzyme DD genotype and D allele compared to control in chronic renal failure patients can be a significant factor in the development of renal failure. © 2019 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

It tries to investigate how, what the researcher calls the imperative mood-lexical aspect dichotomy, affects certain stative verbs, and makes them used imperatively. The study aims to answer some questions like, 'Can all stative verbs be imperative? And if they are used imperatively, can such verbs be used for the default imperative purpose of commanding?' It is hypothesised that not all statives can be used imperatively, and such verbs cannot be used to fulfill commands which are the basic purpose behind imperatives. The procedures followed here include surveying the literature available for the imperative mood, aspect, statives and dynamics. Then, the researcher tries to establish the relation between mood and aspect, with special focus on such a relation in the domain of stative verbs that can be changed into dynamic. The researcher collects examples from the available references of English grammar to show and explain how such group of verbs can be used imperatively. The study concludes that such stative verbs, which the researcher calls the grey area verbs, suffer from a change in their semantics and specifically their lexical aspect. It is this kind of change which allows them to be used imperatively. It is also concluded that only stative verbs that change their lexical aspect into activity or process, may be capable of occurring in the imperative mood.. © Primrose Hall Publishing Group. | Primrose Hall Publishing Group | 22011315 | |

This paper discusses the outcome of an experimental study consisting of 28 runs, with the aim of achieving minimum hydrodynamic forces and maximum energy dissipation downstream of hydraulic structures through stilling basins with directional diverting blocks, DDBs and straight wall baffle, and SWB. Stilling basins with a distinct configuration were made for this purpose. The hydraulic parameters that were involved were evaluated and experimentally analyzed using a rectangular flume in the hydraulic laboratory of the University of Thi-Qar, Thi-Qar, Iraq. Two different kinds of DDB models were made of wood with a triangular form, and the striate line impact wall had intiidinid tininiidni. The study showed that the configuration characterized by two rows of DDB with SWB between them is the most effective in dispersing energy. Out of all the suggested constructions, the DDB are more effective with two or more rows, rather than the SWB, but they are subjected to forces in the flow direction. © 2019 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

These storms restrict the financial activities of the city with expanded municipal effort as well as other well-being and environmental problems, and then bring a huge risk to the local residents. This paper uses Geographic Information System (GIS) and Remote Sensing Imagery to dimensionally discover the reasons causing sandstorms, understand the changes within certain periods of time, and then measure the sand-plume coverage during storms. This work has also made an attempt to get the correlation between meteorological records and spatial outputs to predict the direction and coverage range of the predicted future sandstorms which could help to take protective and preventive measures for the sake of the human being. The periods between 1972 and 2018 have been adopted to study the phenomena by using the information archive of the Nasiriyah Meteorological Center together with NASA's open-source climate data and Landsat satellite imagery. © International University of Sarajevo. | International University of Sarajevo | 23034521 | |

Thus, buildings should be designed and constructed to resist seismic forces. This is not always the case. Most of typical fibre reinforced concrete residential buildings in Iraq are designed and constructed to resist gravity loads only without any considerations to earthquake resistance. It is generally assumed by designers that the seismic forces on low and high-rise buildings are low. The building frame structural system and infill walls are assumed to resist such loads. There has been no verification to these assumptions by designers. Several seismic evaluation methodologies exist over around the world including qualitative (empirical) and quantitative (analytical) methodologies. The most suitable seismic evaluation methodology to be used in Iraq is the analytical methodology of pushover analysis since it does not require an observed damage data from previous earthquakes. We have designed two building that could withstand the earthquakes and have been long lasting using the fibre reinforced concrete. The orientation of the long dimension of columns is an important factor in the seismic resistance of both buildings. The direction contains the long dimension of columns have an earthquake resistance larger than the other direction. Buildings having structural walls behave better than other buildings during earthquakes as long as the location of these walls does not form a horizontal irregularities. © International University of Sarajevo. | International University of Sarajevo | 23034521 | |

Numerous researchers have endeavoured to enhance the performance of steganography techniques through the development of an effective algorithm for the selection of the optimal pixel location within the host image for the concealment of secret bits, for the enhancement of the embedding capacity of the secret data, and for maintaining the visual quality of the host image (stego image) in an accepted rate after the concealment of the secret data. Therefore, steganography is perceived as a challenging task. Thus, the current study proposes a new technique for image steganography based on particle swarm optimisation (PSO) algorithm by using pixel selection for the concealment of a secret image in spatial domain, for the purpose of high embedment capacity. The stego possesses a high level of resistance against a steganalytic attack due to the security provided via image steganography. The function of PSO algorithm is to choose an optimal pixel in grey scale host image for the concealment of secret bits, as the PSO has the ability to achieve an efficient fitness calculation that depends on the cost matrix by dividing the host and secret images into four parts. First of all, the secret bits are modified, which are then embedded within the host image. Several locations in the host image are determined through the order of scanning the host pixels and starting point of the scanning for better least significant bits LSBs of each pixel. The PSO algorithm was utilised to ascertain the ideal initiating point and scanning order. Experimental results show that (1) the average peak signal to noise ratio PSNR value in the benchmark technique based on genetic algorithm for five standard stego images is 45.13%, whereas the result obtained from the recommended technique is 56.60%. (2) The proposed technique has an advantage over the benchmark with a percentage of 33.34%, which encompasses all associated issues within the checklist scenario. Therefore, the performance of the recommended technique is superior over existing techniques. © 2019 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Firstly, benzoate hydrazide [A] has been synthesized from the condensation of ethyl benzoate with hydrazine.Then the benzoate hydrazide was reacted with phenylisothiocynate to prepare [B]. Cyclization reaction of product [B] with sodium hydroxide produced terazole derivative [C].On the other hand, alcylation reaction of compound [C] with chloroethylacetate in the presence of Sodiumacetatetrihydrate as a catalyst resulted [D]. The acid hydrazide derivative [E] has been synthesized by the reaction of compound [D] with hydrazine hydrate. Finaly, hydrazone derived [M] was synthesized by the condensation reaction of the acid hydrazide [E] with 5-bromo-2-hydroxy benzaldehyde. The synthesized compounds were characterized by UV-Visible, FT-IR, 1H-NMR,13C-NMR and Mass spectra. Analytical spectrophotometric study of the complexes of Lead (II),Cobalt(II) and Cadmium (II) with the hydrazone[M] was achieved. At a pH value of 7.0. lead, cadmium and cobalt salts reacted with [M] to form a 1:1 yellow, 1:1green, and 1:1 viole complexes with absorption peaks at 397, 389, and 396 nm, respectively. Under the optimal conditions, Beer's law was obeyed over the ranges of 0.01- 0.000001 The apparent molar absorptivity and Sandell's sensitivities were 8.5 ×102,8.0 ×103, and 9.8 ×102 L·mol−1·cm−1 respectively, and 0.00964, 0.00600, and 0.00275 µg·cm-2 respectively.

Many researchers have focused on the high costs of the low-range buildings and energy consumption, though the energy nodes were limited. Here, the researchers have proposed a novel hybrid system for determining the inside range of the WSNs based on the Received Signal Strength (RSSI) and the DV-hop inside the network. This system was tested by developing nodes based on the XBee S2. The practical experiments showed that the proposed system was reliable and accurate, consumed low energy and displayed a better network range. © School of Engineering, Taylor’s University. | Taylor's University | 18234690 | |

Objectives: The study aims at assessing the knowledge of pregnant women of Gestational Diabetes Mellitus (GDM), which includes screening importance, risk factors and post- partum follow-up. Methodology: A sample of 50 women was selected from primary health care centers in Nasiriyah. The data was collected by interviewing women. The questionnaire was designed and consisted of demographic components and variables and risk factors that contribute to gestational diabetes to pregnant women. The validity and reliability of the questionnaire was determined by conducting a pilot study. Statistical and statistical procedures were used to analyze the data. Results: The study results showed that most of them ranging from age (21-25) years and the highest proportion of them graduated from primary school and less, most of them housewives with enough to some extent. There were statistically important variances between the knowledge of pregnant women about gestational diabetes and demographic data at a value of p less than 0.05. Recommendations: Visit prenatal clinics until late pregnancy, meaning that there is little chance to educate illness on GDM and how they can help prevent it. While doctors are proactively trying to change this, the results of this study suggest that continuing education is necessary to improve awareness of GDM, and early prenatal education is likely to be important and that the Department of Health is setting up workshops on pregnancy.

The initial values of the TD-ERCS system are generated from a user's password, and the TD-ERCS system is used to scramble the pixel locations of the R, G, and B matrices of the original image. Next, three DNA-sequence matrices are generated by encoding the permuted color image such that it can be transformed into three matrices. Then, the TD-ERCS system is employed to generate three chaotic sequences before encoding the DNA into the three matrices. Thereafter, a DNA exclusive OR (XOR) operation is executed between the DNA sequences of the permuted image and the DNA sequences generated by the TD-ERCS system to produce three encrypted scrambled matrices. Finally, the matrices of the DNA sequences are decoded, and the R, G, and B channels are recombined to form an encrypted color image. The results of simulation and security tests reveal that the proposed algorithm offers robust encryption and demonstrates the ability to resist exhaustive, statistical, and differential attacks. © 2019 Haidar Raad Shakir. | Hindawi Limited | 16875680 | |

The high-fidelity large eddy simulations turbulence model is utilized to examine the flow-induced vibrations in the draft tube of the unit. The water injection from the runner cone is considered as the control strategy to mitigate the flow-induced fluctuations. The simulations are conducted for the turbine flow rate of 0.2 m3/s without and with the water injection at a rate of 0.008 m3/s. The pressure along the surface of the draft tube is probed at various locations to access the effectiveness of the water injection to mitigate fluctuations. Water injection at 4% rate is demonstrated to be effective in attenuating the pressure fluctuation inside the draft tube. The amplitude of fluctuations is reduced by nearly 50% by the water injection. The generated power is hardly influenced by water injection. Thus, the control strategy considered here could be employed effectively without a penalty on the power generation. Copyright © 2019 ASME. | American Society of Mechanical Engineers (ASME) | | |

Rossin College of Engineering and Applied Science, Lehigh UniversityPA 18015, United States | Computational fluid dynamics simulations are conducted to characterize the spatial and temporal characteristics of the turbulent flow fields inside Francis turbine operating at the design and partial load regimes. High-fidelity large eddy simulations turbulence model is applied to investigate the flow-induced vibrations in the draft tube of the unit. The water injection at 4% rate from the runner cone is implemented to control the flow-induced pressure fluctuations. The simulations are conducted at the turbine design point and two partial load operations with and without water injection. It has been demonstrated that the water injection has a profound influence in the turbulent flow structure and the pressure field inside the draft tube at the partial load operating conditions. To evaluate the effectiveness of the water injection techniques in mitigating flow-induced fluctuations, the probes at various locations along the wall of the draft tube are used to monitor the pressure signals. It appears to be a reduction in the level of pressure fluctuations by the water injection at both partial load operating regimes. However, we could not draw a firm conclusion about the level of mitigation of flow-induced vibrations. Simulations should be carried out for much longer flow time. Water injection hardly influenced the unit power generation. Hence water injection can be employed effectively without a major liability on the power generation.

An experiment of crack detection in an aerospace grade aluminum sheet metal alloys was designed using an array of piezoelectric wafer active sensors (PWAS). Gaussian-distribution based damage mapping algorithm was used for analyzing the guided wave signals. Since multiple modes of Lamb waves often complicate the guided wave scattering, this can pose a significant challenge for an algorithm's functionality. Mode rejection using appropriate tuning of the PWAS was used to selectively excite a single Lamb wave mode. In this case, symmetric Lamb waves were excited in the structure.

Box 33, PC 616, Nizwa, Oman; Jiheel, A.K., Mathematics Department, Theqar University, Iraq | This paper considers a class of an efficient 'two-stage shrinkage testimator' (TSST) of 'reliability function' of 'exponential distribution', and the class uses additional information which can be obtained from the past practices, and in the form of past initial estimates (λ0) about the unknown parameter λ. The TSST is dependent upon a convenient shrinking factor, conventional estimators, the 'right censored plan' of sj 'ordered observations' of a variable sample of 'size' Sj and by developing five 'testing regions' for screening the 'closeness' of λ0 to λ by different 'criteria'. The computations of 'bias', 'mean squared error', 'expected sample size' and 'relative efficiency' show that the behaviour of the class of 'TSST' is almost similar to existing testimators and better than classical and similar estimators in several properties, for different constants and variables involved in it. Throughout the paper an application to a 'life time' problem is provided to illustrate applicability of the 'TSST' and expressions that are obtained from it. The behaviour of the developed 'TSST' and the significant comparative results offer some useful and sufficient insights for researchers to continue in the 'TSST' direction, and give adequate reasons for experimenters/practitioners to use 'TSST' in their applications. © 2019 Inderscience Enterprises Ltd. | Inderscience Publishers | 1479389X | |

The effect of pH, adsorbent dosage and contact time were investigated. Increase in the pH to neutrality resulted in the increase in the phenolic compounds adsorption capacity. The results showed that the increase in the fiber palm dosage to 0.5g/0.1L significantly increased the phenolic compounds adsorption rates. The adsorption process was fast, and it reached equilibrium in 30 min. contact time. The Freundlich and Langmuir adsorption models were used for mathematical description of the adsorption equilibrium and it was found that experimental data fitted very well to both Freundlich and Langmuir models. These results indicate clearly the efficiency of fiber as a low-cost solution for these compounds in aqueous solutions treatment and give some preliminary elements for the comprehension of the interactions between palm fiber as a bioadsorbent and the very polluting compounds from aqueous solutions. © 2009-2019, JGPT.

In this paper, a series of unconfined compression and triaxial tests were conducted on sand and sand-ground granulated blast-furnace slag (GGBFS) based geopolymer. A solution of sodium silicate and sodium hydroxide was employed for the geopolymerization process. Results revealed that adding the GGBFS resulted in a significant increase in the strength properties. This result indicates that geopolymer acted as a cementation agent, providing better bonding between the sand particles and consequently improving the performance of the treated sand. © Czech Technical University in Prague, 2019. | Czech Technical University | 12102709 | |

During field loading, maximum moments of between 74% and 87% of the moment caused by AASHTO HL-93 loading with impact were applied to the structures. Strain readings indicated partial to full unintended composite action and significant restraint at the girder ends for all structures. HL-93 operating load ratings were modified using the strain measurements recorded during diagnostic load tests, leading to an average increase in moment rating factor of 52%. A novel approach of calibrating 3D FE models was developed that captures the observed full and partial composite action observed during testing, as well as restraint of the girder ends, giving good agreement between model-predicted and measured strains. The FE models were used to directly predict bridge capacities and rating factors while explicitly capturing girder yielding and load redistribution. The effects of unintended composite action, end restraint and concrete deck stiffness on capacity were examined using these models. The most conservative FE-estimated rating factors that ignored unintended composite action and end restraint - which are likely unreliable at large loads - were 54% higher than the conventional, code-based rating factors. © 2019 - IOS Press and the authors.

In current paper, a new method of face verification upon on singular value decomposition (SVD) and standard deviation (SD) would be described. Due to many variations in real-life such as pose, illumination, or facial expression, there would be difficulty of face recognition. It should be mentioned that there are many approaches for face recognition, however, there is no one could be considered as the most suitable for many situations. One of the methods used is Singular value vector for an image detecting, but the drawback of this approach is the low rate of recognition, where one scale singular value vector is used for face acknowledgment. There an algorithm has been developed to expand the rate of the recognition. In this paper, an approach has been proposed to associate two feature sets obtained from SVD and SD method. It has noticed a good recognition rate could be obtained from the experimental results, where approximately more that 97.5% recognition rate has obtained on the ORL data base. The results from current proposed method have matched with some techniques and it has shown that this method is better than the existing approaches. An extensive experiment has demonstrated not only better performance, but it offers a great likely to achieve equivalent performance to other categories of state-of-the-art methods. © 2019 International University of Sarajevo. | International University of Sarajevo | 23034521 | |

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | Vortex identifications in turbulent flows past arrays of tandem plates are performed by employing the velocity field obtained by high-fidelity large eddy simulations. Lagrangian coherent structures (LCSs) are extracted to examine the evolution and the nonlinear interaction of vortices and to characterize the spatial and temporal characteristics of the flow. LCSs' identification method is based on the finite-time Lyapunov exponent (FTLE), which is evaluated using the instantaneous velocity data. The simulations are performed in three-dimensional geometries to understand the physics of fluid motion and the vortex dynamics in the vicinity of plates and surfaces at Reynolds number of 50 000. The instantaneous vorticity fields, Eulerian Q-criterion, and LCSs are presented to interpret and understand complex turbulent flow structures. The three-dimensional FTLE fields provide valuable information about the vortex generation, spatial location, evolution, shedding, decaying, and dissipation of vortices.

The present study aims to identify the most suitable solid waste disposal site using Geographic Information System (GIS), remote sensing, and the multi criteria decision-making (MCDM) technique. In addition, the study compares the proposed method for suitability with the traditional analytic hierarchy process (AHP) approach. A new validation approach was applied to evaluate the accuracy of the AHP and Fuzzy logic methods based on the selected solid waste locations. Remote sensing data (ASTER GDEM) and field/reference maps were used to derive 12 conditioning factors required to produce a suitable location for solid waste disposal. The result shows that the accuracy of AHP, based on the consistency index (CI), is acceptable (greater than 0.1). However, Fuzzy logic was shown to be more accurate than AHP. The total surface areas of suitable locations based on AHP and Fuzzy models are 4.4 km2 and 13.35 km2, respectively. This study showed that AHP, Fuzzy logic and GIS can be integrated for waste management decision issues related to site selection to reduce negative effects on the environment and inhabitants. © 2019, ALÖKI Kft., Budapest, Hungary. | Corvinus University of Budapest | 15891623 | |

Clinically, the spots of pityriasis alba are off-white in color, round with poorly defined margins that bear scanty fine scales on it. No specific cause of pityriasis alba has been identified. In this disease, the number of melanocytes declines and melanosomes reduce within melanocytes. Vitamin D exerts its effect via the vitamin D receptor on melanocytes, if intracellular Ca2+ level decreases, this leads to high levels of reduced thioredoxin this, in turn, inhibit tyrosinase activity with the inhibition of melanin synthesis. In addition, the apoptotic activity of melanocytes reduces by the active form of vitamin D. Aim: The study aimed to assess the status of vitamin D for patients with pityriasis alba. Materials and Methods: 44 patient diagnosed with pityriasis alba were enrolled and the second group of 44 controls was involved in our study. Serum levels of circulating 25 (OH) D were measured. Results: None of the cases had sufficient serum level; the level ranged between 8.1-27.3 ng/ml. The patients had lower circulating vitamin D levels than controls. Conclusion: Our findings in the present study are significant, but further studies with large samples are needed to correlate the extent and severity of pityriasis alba with vitamin D deficiency. © 2019 Kattoof and Kawen.

Its data and software could be reached at any time and from any place. Due to the large amount of requests received from cloud users, cloud service provider should manage all requests efficiently. This paradigm is called load balancing. Load balancing aims to distribute all requests among datacenter nodes such that avoiding node overload or underload. In this paper, we proposed a modified Round Robin (RR) algorithm for load balancing. The presented approach relies on computing two time quantum in each round. It is compared with many other algorithms such as: ERR, ORRSM, EDQRR, DABRR, and SRDQ. The experimental results show that our algorithm outperforms the others.

Results: Searching resulted in twenty-one matched studies. Extraction of data showed an incidence rate of new-onset atrial fibrillation (2.8%-58%). A negative impact was found on the outcomes of patients treated with primary PCI with increased short and long-term mortality and morbidity. Conclusion: New-onset atrial fibrillation is an adverse prognostic marker in patients with acute myocardial infarction treated invasively. Preventive measures and anticoagulant therapy should be considered more intensively in this subset of patients. © 2019 F. Al-Obaidi et al., published by Sciendo. | Sciendo | 3241750 | |

Samples of larvae were collected from Iraq. The larvae were exposed to various temperatures 30, 35, 40, 45 and 50°C for 10 minutes (as heat shock period). Larval mortality was recorded. The data was analyzed to calculate the quantity of heat (kj) that was added, the corrected mortality, the regression line and the correlation coefficient. It was found that heat shock of 30°C has no effect on larvae, but heat shock of 35, 40, 45 and 50°C produced mortality, while heat shock of 30 and 35°C has no effect on some aquatic organisms. The heat shock of 40.6°C and 48.94°C produced mortality in 50% and 95% of larval populations, respectively. The study showed that the heat shock of 40°C can be used to control the aquatic stages (Larvae) of mosquito (Anopheles arabiensis).

The most effective procedure to measure the degree of land-cover and land-use changes is the multi-date study. For this purpose, the aim of this work is to analyze the current evolution of land-use and land-cover (LULC) using remote sensing techniques, in order to better understand this evolution. For this purpose, a diachronic approach is applied to satellite images acquired in 1987 to 2018 of Ma’rib city Yemen. The LULC maps we obtained were produced from different image analysis procedures (non-supervised classification and recode technique) to map the land-use and land-cover. The objective of this study is to apply reproducibly and generalizable a predefined nomenclature to different scenes of satellite images. The first step consists in interpreting the radiometric classes obtained by non-supervised classification so as to form the classes of the thematic nomenclature. An improvement of the classification is then obtained by using the recode technique which makes it possible to correctly reassign the previously badly classified pixels of the satellite images classification. Land-cover maps obtained from remote sensing were used to quantify the rate of change (Tc) and (Tg) of area occupied by each class. The results will indicate the most changeable period and the percentage of overall change in the study area (Ma’rib Yemen), and helped to identify and characterize the spatial and temporal evolution of land use in the district over a period of thirty-one years (1987 to 2018). They reveal that annual average rates of decline for the water body is -83.5% and -9.96% for the sandy land. However, it was observed an increase in built-up area 365.52% and farm land 324.52% classes. © Authors 2019.

B. orientale is an edible fern that is used as a food and in traditional medicine. This study assessed the total phenol content (TPC) and antioxidant activity by three different assays (DPPH, FRAP and ORAC) of the 50% aqueous acetone extracts of B.oriental parts sampled from two selected location (UKM Fern Garden and Chini Forest). The extracts analyses were prepared from the young fronds, mature fronds, rhizome, and fiddlehead of the sampling fern. ANOVA test at P < 0.05 determines significant differences between various parts extract. It was found the TPC of young frond extract of B. oriental had the highest contents (1360 and 1643 mg GAE/100g DW) in UKM Fern Garden and Chini Forest respectively. While the antioxidant activity of plant extracts by DPPH, FRAP assay and ORAC value for all parts of B. oriantle was very high at both locations. It illustrated that there is strong antioxidant activity for all parts of plant, especially for Chini Forest and that correlate to diversity of climatic and geomorphological features. A good linear significant correlation coefficient was detected between the TPC and FRAP (p < 0.01), and among the assays were compared with each other (DPPH, FRAP and ORAC), (p < 0.05) from both location. These findings provide scientific evidence to support its traditional medicinal importance which is potentially rich sources of natural antioxidants. © 2019 Plant Archives.

The most important elements are wind, dust storms, temperature, acid rain, air pollution and its role in environmental pollution and its negative impact on the local environment and the urban environment. We noticed the pollution of city streets more than rural streets, open areas and study results. Heavy metal concentration levels were determined using AAS after digestion of dust samples in vitro (Al-Janabi et al., 1992). The results showed that the concentration of some heavy metals was high in this study. The differences in the percentage of lead concentration were from (97.3) to (266) ppm. The concentration of cadmium was from (7.3) to (13.9) ppm, the range of Zn from (55) to (104) ppm, while the concentration of copper, Ni and Cu ranged from (13) to (34.1) ppm, (11.7) to (34.2) ppm and (12) to (25.4) ppm, respectively. The variation in coefficients showed that one group of metals was affected. The analysis of the component of the principle of human pollution resulted in two main components PC1 with a high load of Pb, Cd, Zn, the proposed result of industrial activities and PC2 with the contribution of Cu, Cr and Ni due to soil factors, Humanity. The environmental state of the soil was recorded by calculating geochemical loads (GLI) for each mineral. The concentration of heavy metals was significant in each element, which was shown by concentrations of the six elements studied in this study. © 2019 Plant Archives.

However, such material has been used in several geotechnical applications as alternative lightweight backfill in highway embankments and/or behind retaining walls, providing environmental, economic and technical benefits. These applications require knowledge of engineering properties of soil-tire rubber mixtures. The present study aims to show the possibility of tire rubber usage in sand by evaluating the shear strength and deformability of sand mixed with granulated rubber, in weight percentages between 0 and 50%. The tire rubber content was found to influence the stress-strain and deformation behavior of the mixtures. The shear strength of sand mixed with 10% or 20% tire rubber was higher than that measured for sand only. However, the trend for TRC = 30-50% was different. Samples with a rubber content of 30-50% exhibited a rapid decrease in the stress ratio compared with that of sand. The major principal strain at maximum stress ratio was found to increase with increasing tire rubber content. However, it was observed that the lateral strains (minor and intermediate principal strains) of samples reduced significantly with the addition of tire rubber to the sand. © 2019 Alaa H. J.

Practically speaking, injudicious use and inappropriate discharge of all forms of hydrocarbons compounds are harmful for the ecosystem. On the other hand, hydrocarbon components like polyaromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) and their biodegradation products are known for their carcinogenic behavior. The reason of persistence of carbon-based compounds (petroleum hydrocarbons) for a long time in the ecosystem depends on many factors such as the physical factors, type of soil, type of microbes in that particular environment, water and sediment of that area, and above all the chemical nature of the petroleum hydrocarbon. The degradation rate of any hydrocarbon product depends upon the chemical nature of the compound, influence of physical factors (here temperature plays a significant role), and accessibility of hydrocarbon as carbon source for microbes, especially the extracellular enzymes secreted by the microbes. The hydrocarbon compounds released in the soil sediments are easy to degrade compared to the aquatic system; since the diversity of microbes in soil and sediment is more, therefore, released hydrocarbon compounds are easily degraded into simple and nontoxic components. Filamentous fungi are a very important biodegrader, owing to their greater biomass compared to bacterial cell. The fungi have more surface area for biosorption and enzyme secretion for efficient biodegradation of petroleum hydrocarbons. In addition to fungi, other organisms such as bacteria and algae have also been employed as an efficient hydrocarbon biodegrader. The main problem with petroleum hydrocarbon biodegradation is that owing to the recalcitrant nature of petrochemicals, the process is complicated, and it also takes a long time for mineralization. Environmental factors also determine the fate of petroleum hydrocarbons in aquatic and terrestrial ecosystem and also rely on several climatic conditions such as temperature, light, aerobic and anaerobic conditions, pH, wind, availability of nitrogen compounds, presence of humic acids, and salinity. There are several methods and approaches used all over the globe to remove or biodegrade the unwanted hydrocarbons using physical and chemical means, but these approaches are not efficient, and moreover they are not cost-effective. The use of biological means by applying potential microbes for bioremediation is an efficient, eco-friendly, and cost-effective tactic without addition of any unwanted load on the environment. © Springer Nature Singapore Pte Ltd. 2018. | Springer Singapore | | |

The distribution of stresses and distortions with aerodynamic loads is studied. Factors such as tension, pressure and shear stress showed on wing of UAVs due to vibration which caused the structure of wing to break down and then failure. The experimental study was carried out by using wing made of composite material (foam and cover by lamination plate), where airfoil type (NACA Clark y) installed inside wind tunnel of low velocity. It is found that the vibration acceleration at constant wind velocity with variation of attack angle of the wing, it is obtained the relationship between the acceleration and the frequency using the LABVEIW program which analyzed and identified the distribution of forces on the wing. The stress concentration areas is created and found under failure occurs, the aerodynamic force, torsion torque and magnitude of deformation is calculated. It is concluded that the close areas from the root wing (fixed end) is most likely to collapse or break. © 2019 by authors. | Horizon Research Publishing | 23323353 | |

Many schemes have been developed to provide authentication mechanisms to ensure that only legitimate users are authorised to connect, but these schemes still suffer from vulnerable security. Various attacks expose patients' data for malicious tampering or destruction. Transferring health-related data and information between users and the health centre makes them exposed to penetration by adversaries as they may move through an insecure channel. In addition, previous mechanisms have suffered from the poor protection of users' authentication information. To ensure the protection of patients' information and data, we propose a scheme that authenticates users based on the information of both the device and the legitimate user. In this paper, we propose a Robust Authentication Model for Healthcare Users (RAMHU) that provides mutual authentication between the server and clients. This model utilizes an Elliptic Curve Integrated Encryption Scheme (ECIES) and PHOTON to achieve strong security and good overall performance. RAMHU relies on multiple-pseudonym, physical address, and one-time password mechanisms to authenticate legitimate users. Moreover, extensive informal and formal security analysis with the automated validation of Internet security protocols and applications (AVISPA) tool demonstrate that our model offers a high level of security in repelling a wide variety of possible attacks.

QoS mainly concerns minimizing the total completion time of tasks (i.e., makespan), response time, and increasing the efficiency of resource utilization. One of the most investigated techniques to meet QoS requirements in the cloud environment is adopting novel task scheduling strategies. Based on our studies, we found that existing solutions neglect the difference in efficiency of resource performance or the starved processes, which can strongly affect the scheduling solution outcome. In this paper, we consider this difference and propose a Hybrid-SJF-LJF (HSLJF) algorithm, which combines Shortest Job First (SJF) and Longest Job First (LJF) algorithms, while considering the load on resources. To start with, the algorithm sorts the submitted tasks in ascending order. Next, it selects one task according to SJF and another according to LSF. Finally, it selects a VM that has minimum completion time to execute the selected task. The experimental results indicate the superiority of HSLJF in minimizing the makespan, response time, and actual execution time while increasing the resource utilization and throughput when compared to the existing algorithms. © Springer Nature Singapore Pte Ltd 2019. | Springer | 23673370 | |

By taking a discrete time delay as bifurcation parameter, we investigate the nonlinear dynamical behaviour arising from the model, using mathematical tools such as stability and bifurcation theory. Firstly, we discuss the existence and uniqueness of the equilibrium for this system and investigate the effect of discrete delay on its dynamical behaviour. Absence or limited delay causes the system to have a stable equilibrium, which changes into a Hopf point producing oscillations if time delay is increased. These sustained oscillation are shown to be present only if the nonlinear degradation rate for mRNA satisfies specific conditions. The direction of the Hopf bifurcation giving rise to such oscillations is also determined, via the use of the so-called multiple time scales technique. Finally, numerical simulations are shown to validate and expand the theoretical analysis. Overall, our findings suggest that the degree of nonlinearity of the model can be used as a control parameter for the stabilisation of the system. © 2019 the Author(s). | American Institute of Mathematical Sciences | 15471063 | |

The study is performed experimentally for turbulent flow system with use of air as a working fluid for a range of Reynolds number between 10000 to 50000. The conical nozzles integrated with triangle fins are utilized as turbulators to generate more complex mixing flow along the pipe wall. The plane conical nozzles turbulators are used for three various pitch ratios (Pr=1.0,1.5 and 2), and those fitted with triangle fins are tested at pitch ratio Pr=1.0 with two various area ratios of 0.064 and 0.149 respectively. The heat transfer of conical turbulators integrated with triangle fins is enhanced by 274% as compared with plain pipe and 55% as compared with inserted conical nozzle turbulators alone for the larger area ratio (Ar =0.149). In the addition, the Conical nozzle turbulators fitted with triangle fins give optimum overall thermal performance as compared with unfinned conical nozzle turbulators and plane tube. © 2006-2019 Asian Research Publishing Network (ARPN). | Asian Research Publishing Network | 18196608 | |

MicroRNAs are considered as significant regulators of cancer biological processes. The main aim of this study is restoration of miR-126 could lead to modulate breast cell line and impairs their proliferation by targeting vascular endothelial growth factor gene (VEGF-A). Methods: Breast cancer cell line (MCF7) was transfected by miR-126 lipofectamine and negative miR control for 24 hr. Cytotoxic effects of miR-126 lipofectamine were determined by cell viability assay. Cell proliferation and cell cycle were quantitatively measured using PicoGreen assay and DAPI stain-flow cytometer analysis. For further investigation, Taq-Man real time PCR assay was performed to detect relative VEGF-A and miRNA-126 level. Results: MiR-126 was overexpressed in treated breast cancer cell (MCF7) compared with control cells. miR-126 expression has been associated -with a decrease in cell proliferation and arrested MCF7 cells at G1 phase. The study found that vascular endothelial growth factor is regulated by miR- 126. Hence, VEGF-A is considered as functional vital and direct target to miR-126 in breast cancer cell line (MCF7). Conclusions: This study provided that manipulated miR-126 level may suggest a novel therapeutic approach in breast cancer treatment. However, an animal models study is needed to address and prove predictive ability of miR-126 on breast cancer controlling. © 2019 Asian Pacific Organization for Cancer Prevention. | Asian Pacific Organization for Cancer Prevention | 15137368 | |

Depending on the optical feedback (OFB) strength a complex bifurcation scenarios for the photon intensity were completely determined by the variation of the OFB in the QD as well as time series, inter-spike interval (ISI) and phase plane of all dynamic variables of the QD-LED. Our results show that small OFB lead to a good controllability of QD-LED dynamics as evidenced by the bifurcation diagram. The delay time leads to delay control of dynamics. Moreover, bias has a clear and greater effect than that of OFB. By adding a grating mirror as a special technique to suppress unwanted frequencies, there is an important transition between periodic and chaotic states. Delayed feedback and turn-on dynamics are studied. © 2018 Elsevier Ltd | Elsevier Ltd | 9600779 | |

However, the performance of such systems degrades as their size is reduced. Graphene-based nanoelectronics has appeared as a candidate to enable high performance down to the single-molecule scale. Here, graphene nanoribbons (GNRs) can have bandgaps that are tunable by using chemical doping method. We have been predicted that bandgap engineering within a GNR may be achieved by varying the number and geometrical pattern of phosphorus (P) impurities in the GNS, so that we have carried out first-principles calculations of the energetic and electronic properties of P-doped GNR based on density functional theory (DFT) with Gaussian 09W packages. The geometric and electronic properties of the GNR with and without various dopants of phosphorus impurities were performed and discussed. Our results show that the electronic properties of GNR do not only depend on the phosphorus impurity concentrations, but also depend on the geometrical pattern of phosphorus impurities in the GNR. As a result, we can bandgap engineering of GNR by doping phosphorous impurities to create semiconductor heterostructure, which can be used in many important applications. © 2018 | Elsevier B.V. | 13869477 | |

Industrialization and modernization in the last few decades resulted in imbalance of the ecosystem by adding different chemical compounds, such as heavy metals, polycyclic aromatic hydrocarbons (PAHs), radioactive materials, xenobiotic, pesticides, hazardous chemicals and dyes. These compounds badly influenced the biological systems of plants, animals, microorganisms and human being. The high toxicity of some of these polluted compounds also negatively influence the normal function of the body. On the other hand, the presence of toxicants in chemical fertilizers, pesticides and sewage also contaminate the soil and potable water. There are several approaches which can solve the problem to certain extent and these are physical and chemical methods. These methods have some limitations, and not therefore, not that successful, on the other hand are not cost effective and also causes interference with natural water bodies' composition. Moreover, these physico-chemical methods also leads to different toxins and other compounds in the ecosystem. In spite of this, biological methods are now a days available which are eco-friendly and to some extent completely mineralize the organic pollutants. Another positive aspects of the these methods are that they are cost effective and does not generate toxic wastes. These biological approaches employs the potential microorganisms such as bacteria, algae and fungi under aerobic or anaerobic conditions. The use of microbial sources has several advantages mentioned above and have and long term applicability. © Springer Nature Singapore Pte Ltd. 2018. | Springer Singapore | | |

In this work we have compared the thermoelectric properties of FeCP with two different configurations. The results show that the spin-dependent transport properties can be affected by the molecular structure and the substitution of the terminal thiol groups plays an important role on the spin-dependent transmission of the molecular junctions. Meanwhile, electrical conductance and thermal conductance also affected. The thermoelectric properties of Ferrocene (FeCp2) for these two different configurations have been compared. Thus, all these transport properties are combined to produce a good value of the roomerature figure of merit ZT. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

In indoor positioning systems (IPS), WLAN fingerprinting-based methods require recording received signal strength (RSS) of surrounding access points (APs). These are usually more than the necessary number of APs needed by the IPS system. Therefore, eliminating redundant or non-informative APs does not only reduce computational cost, which is necessary for the real-Time system, but also improves the accuracy of the indoor positioning system. In this paper, we present a particle swarm optimization (PSO)-based technique to select the most informative APs at each clustered area, where K-means clustering method is utilized to confine location of the user into a small area. At each cluster, PSO is applied to select the best joint combination of APs decided by the minimum mean of distance error. Simulation results show that the proposed system outperforms the behavior of the other commonly proposed selection methods such as random, strongest APs, and Fisher criterion. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 5473578 | |

Activations have been conducted utilising three agents: Sulphuric acid (H2SO4), potassium hydroxide (KOH), and zinc chloride (ZnCl2). Characterisations of the porosities of AC preparations were performed using N2 adsorption-desorption to ascertain BET and micropore surface areas as well as micropore volumes and pore-size distributions. Existing groups on the AC surfaces were resolved using Fourier Transform Infrared Spectroscopy (FTIR) analyses. The morphologies of the activated carbons were assessed via scanning-electron microscopic methods (SEM) combined with energy-dispersive X-ray spectroscopic techniques (EDX). The maximal surface areas (1639.34 m2/g), pore volume (0.649 cm3/g), micropore volume (0.335 cm3/g), and micropore surface area (1,148.58 m2/g) of the prepared AC using sago palm bark were discovered at activation temperatures of 700oC and with chemical impregnation ratios of 1.51/ zinc chloride to precursors. In the instance of KOH and H2SO4 utilisation, the surface areas of the AC preparations corresponded to 970.38 m2/g and 630.73 m2/g with pore volume of 0.458 and 0.196 cm3/g, respectively. © 2018 University of Kuwait.

The advantageous properties of fiber-reinforced polymer (FRP) composite material promote its use as an alternative construction material for piles in aggressive soil environments. This paper investigates the interface friction characteristics between different granular materials and FRP composites through interface shear testing using a modified direct shear apparatus. Two FRP materials: glass and carbon fiber reinforced polymer (GFRP and CFRP), with different surface topographies, besides mild steel were used as the counterface materials. Additionally, four different types of sands and three types of glass beads (GB) were tested with the counterface materials at different normal stresses ranging from 27.7 kPa to 180.5 kPa. The results indicate that the shear mechanism and resulting friction coefficients for the particulate/FRP interface systems are dependent on a combination of several factors such as the particles size and angularity, the surface roughness of the counterface material, and the applied normal stress level. Additionally, higher interface friction coefficients were measured for both FRP composites compared to the conventional mild steel, demonstrating the applicability of their use in the piles industry. © IAEME Publication. | IAEME Publication | 9766308 | |

The total energy, orbital (HOMO, LUMO) distributions, the energy gaps, the maximum open circuit voltage, maximum wavelength absorption, vertical absorption energies, and oscillator strengths have been investigated and discussed. We studied and discussed effect the donor group substituents (COH, and CP) and the acceptor group substituents (Br, OH, Cl, F, and CN) on optimization geometric, electronic properties, and optical properties the molecules, we observed that the donor group substituents lead to decrease energy gap and the acceptor group substituents lead to increase energy gap. These changes give alteration of maximum wavelengths absorption from 453.1 to 559.9 nm.

This continuing injury trend requires further understanding of the causes of safety issues as well as what magnifies safety risk. This study aims to investigate the extent of the impact of different factors on worker safety risk. The factors, namely human, site conditions, psychological, environmental, social, economic, regulatory, ergonomic, and organizational, were developed as part of recently formulated degrees of connectivity (DoC) model scenarios utilizing the risk perception of different specialists. The risk perceptions associated with the factors as provided by construction safety university professors and practicing safety engineers are explored for comparison. The Delphi method was adopted to collect the required data from both mentioned groups. The results show that the participants perceive that site condition factors create the highest impact whereas the worker economic factor adds the lowest impact. No significant difference was observed between the two groups in terms of risk perception, nor was there a clear impact of participant experience on the risk perception process and the factors under investigation. Safety planners can benefit from the study results by considering the level of impact that the factors have on worker safety. Moreover, when addressing safety on a project, both professors and engineers can contribute equally. © 2018 American Society of Civil Engineers. | American Society of Civil Engineers (ASCE) | 7339364 | |

This new type of lasing, which results from the quantum interference of spontaneous emission components, was not discussed earlier in quantum dot nanostructures. It is found that both pumping and cycling fields control the laser emission. The decrease of the cycling detuning increases the possibility of lasing. Probe detuning controls the width of the absorption bath (electromagnetic-induced transparency window) of this structure. This phenomenon can have an interesting application for developing sources of coherent radiation in a region of electromagnetic spectrum where the implementation of traditional laser schemes is difficult. © 2018, Indian Academy of Sciences. | Springer | 3044289 | |

This work concerns the behaviours of square ferrocement slabs with dimensions of 500 × 500 × 30 mm when subjected to flexural load. This study included testing thirteen ferrocement slabs, and the main variables considered in the experimental work were the number of wire mesh layers, percentage of silica fume and presence of steel fibre. The effects of these variables on the behaviours and load carrying capacities of tested slabs under central loads were investigated. From the experimental results, increasing the percentage of silica fume from 0% to 6% caused ultimate flexural loads to increase up to 4.5% replacement. The load carrying capacity also increases with presence of steel fibre reinforcement, and the ductility is high where steel fibres are included. The results also suggest that an increase in wire mesh layers from six to ten layers leads to an increase in load capacity by 76%. Finally, the results show that the addition of steel fibres can reduce the crack width and increase the number of cracks compared to samples without fibres. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

The present paper aims to investigate the influences of the main process input factors on weld geometry, metallurgical characteristics, and mechanical properties of weldments of 3.8-mm-thick plates of austenitic stainless steel type 304L using tungsten inert gas welding with pulsed/non-pulsed current processes. This research paper investigates the effects on the arc pressure of pulse frequencies at levels of 6 and 1,000 Hz, and thereby their effects on the aspect ratio and morphology of the weld metal. The key outcomes of this work are that the frequency of arc pulsation has a strong effect on the breaking of the dendritic arms during the welding process. The obtained microstructure results reveal that the structure of the high pulse frequency current welded specimens are thus generally finer grained, with higher levels of residual ferrite and an absence of columnar grains; such pulse frequencies thus strongly influence the tensile strength and microhardness of affected weldments as compared to those seen in continuous current welded specimens. Additionally, the most important factor affecting the bead geometry and aspect ratio is identified as the pulse frequency, with a contribution of 64%. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

This study investigates the occurrence, serotypes distribution, antimicrobial resistance, and multilocus sequence types (ST) of Salmonella isolated from 400 imported frozen chicken carcasses sold in the markets of Thi-Qar, south-eastern Iraq. Salmonella was detected in 46 out of 400 tested samples [11.5% (95% confidence interval: 8.5%–15.0%)]. S. Typhimurium was the most abundant (30.4%) among 14 different serotypes recovered from the tested frozen carcasses. Antimicrobial resistance was most frequently detected against tetracycline (84.4%), nalidixic acid (80.4%), streptomycin (69.6%) and trimethoprim/sulfamethoxazole (65.2%). Whole-genome sequencing (WGS) analysis revealed that 18 isolates harbored four β-lactamase resistance genes, with blaCARB-2 was the most commonly (14/18) detected. It was possible to identify 8 multilocus sequence types from the WGS analysis of 40 out of the 46 Salmonella isolates; with ST-11 (among S. Enteritidis) and ST-19 (among S. Typhimurium) were the most frequently detected. These results add to our understanding of the global epidemiology of Salmonella. Our work stands as one of the first reports on WGS analysis of Salmonella from retail chicken in a Middle-Eastern country. Results from this study could be valuable for guiding an informed import risk analysis aiming at reducing the exposure risk from Salmonella through imported chicken carcasses into Iraq. This work demonstrates the value of WGS as a promising tool for supporting evidence-based food safety hazard characterization. © 2018 Elsevier B.V. | Elsevier B.V. | 1681605 | |

The SMD technique is made by depositing a main wire plus cold feed wire melted by arc welding heat. In this paper, the experimental setup consists of MIG-welding plus cold wire feed and 3-axis machine to be able to apply the deposition process paths. The current work focused on investigating the effect of deposition parameters on the wall bead geometry and deposited wall hardness of the deposited specimens. The controlled input parameters in this work were melting current, traveling speed, and wire feed ratio as a new parameter. The results were analyzed by statistical technique, i.e. Analysis of variance and signal/noise ratio. Confirmatory test had been carried out to achieve the validity of results. The results showed that the wire ratio contributes 49.42% towards the overall variation noticed within removed layer thickness. The traveling speed contributes 34.15% of the overall variation noticed within removed layer thickness. Wire feed ratio contributes 59.22% towards the overall variation noticed within hardness. The traveling speed contributes 38.31% of the overall variation noticed within hardness. The optimal value of hardness is 283.521, whereas total removed layer is 0.5791. From the results, it is clear that the wire feed ratio greatly affects the deposited parts quality, and hence this parameter is considered as a new addition to the shaped metal deposition technique using the 3D-SMD plus a cold wire feed. © 2018 IAEME Publication.

The high incidence of ectopic pregnancies can to some extent be related to the fact that the early diagnosis of pregnancy can be made with the use of β-hCG and ultrasound scans to identify the location of an early pregnancy. Objectives: current study was conducted to (1) assess tubal patency by using hysterosalpingography following surgical and medical treatments of tubal pregnancy, and 92) to assess pregnancy rates following surgery and medical treatment of patients with ectopic pregnancy. Methods: an interventional controoled clinical study involved 300 women diagnosed with ectopic pregnancy at Bint-Alhuda Teaching Hospital in Thi-Qar Governorate, Iraq. They were divided into two groups according to the patients’ preference; the first group treated with methotrexate while the second group treated surgically. Hysterosalpingography was done to all patients in both groups after three months of treatment, and both groups were followed up for one year waiting for pregnancy. Results: Tubal patency and spontaneous pregnancy rate is higher in the medically-treated group of patients. The contralateral tubal blockage was 11.5% in surgical-treated group, while 5.85% in medical-treated group. The spontaneous pregnancy rate was higher in medical-treated group (81.81%), while (58.66%) in the surgical-treated group. Conclusions: Better fertility potential and hysterosalpingography findings have been found after the medical treatment for patients with tubal ectopic pregnancy than those who are treated surgically. © 2018, Indian Journal of Public Health Research and Development.

The study concerns the compressive and flexural strength of concrete with polypropylene fiber (PF). The experimental phase of the research has included testing fifteen groups of concrete with different characteristics. The main variables considered in the experimental program are the percentage of polypropylene fiber, type of concrete mix and presence of steel reinforcement in a prism. The effect of these variables on the compressive and flexure strength of concrete was investigated. The results of this study indicated that the variation in the compressive and flexure strength of concrete depends mainly on the polypropylene fiber percentage. It was found that the compressive strength of concrete increases by increasing the percentage of polypropylene fiber from 0 to 0.2%, while the increasing in the strength started to vanish when approached to 0.3% of PF. Similarly, the flexural strength of concrete has also increased by increasing the percentage of PF from 0 to 0.3%. By further increasing PF up to 0.5%, it was determined that the compressive and flexural strength of concrete started to decrease significantly as compared to the control mix. ©IAEME Publication | IAEME Publication | 9766308 | |

Current study was aimed to observe the lipid profile, malondialdehyde, antioxidant and electrolyte levels in type 2 diabetes mellitus patients. Methods: Serum glucose, total cholesterol, triglycerides, high density lipoprotein, very low density lipoprotein and low density lipoprotein, malondialdehyde (MDA), ceruloplasmin, uric acid, sodium, potassium and chloride levels were determined in 75 patients with type II diabetes mellitus and 25 healthy subjects. Results: The levels of serum glucose, total cholesterol, triglycerides, very low density lipoprotein, low density lipoprotein, malondialdehyde, ceruloplasmin, sodium, potassium and chloride showed significant increase in ype II diabetes mellitus patients as compared to control group whereas the levels of high density lipoprotein and uric acid showed a significant decrease in type II diabetes mellitus patients in comparison to control subjects ( P ≤0.05 ). In addition, current study demonstrated the characteristic diabetic dyslipidaemia which is characterized by low HDL and high triglyceride. Increased levels of MDA may be a useful marker of oxidative stress. Increased oxidative stress may result in consumption of antioxidants including ceruloplasmin. Also, there is significant decrease in serum uric acid levels in type II diabetes mellitus patients. It may be concluded from this study that dysregulation of glucose homeostasis may lead to electrolytes imbalance due to increase in sodium and potassium chloride levels. © 2018, Pharmainfo Publications.

Methods: Allicin solution at different concentrations was tested on A549 lung cancer cell line. Viability and proliferation of A549 cells were determined. The cytotoxic effects of allicin solution on A549 lung cancer cells were quantitatively determined using Alamar blue assay. Cell proliferation and cell cycle were measured by DAPI-flow cytometry analysis in order to investigate the possible cell signalling pathway targeted by allicin. The level of expression of VEGF-A protein was determined with confocal laser scanning microscopy. Results: Allicin inhibited lung cancer proliferation and down-regulated the protein expression of VEGF, but had no significant cytotoxic effects on A549 cells. Flow cytometric results showed that allicin induced cell cycle arrest of A549 cells at the G1 phase. Conclusion: These results indicate that allicin exerts anti-proliferative effects on A549 lung cancer cells. Thus allicin, an active component of garlic, might be a promising therapy against lung cancer metastasis. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria and 2018 The authors. | University of Benin | 15965996 | |

Many drugs nowadays have been reported to have a clinical efficacy against cutaneous leishmaniasis but only a few have been proven worthy. In this study, we aim to compare the efficacy and safety of Intralesional sodium stibogluconate (Pentostam® 100 mg/mL) and Intralesional metronidazole (flagyl® 5 mg/mL) solutions in the treatment of cutaneous leishmaniasis. METHODS: A clinical trial was done in Dermatology Consultancy Clinic of Al-Hussain Teaching Hospital, Nassiriah (Thi Qar Province Center), Iraq, during the period from June 2015 to June 2016 on a convenient sample of 100 patients with cutaneous leishmaniasis. Those patients were assigned randomly into two groups according to type of localized treatment (50 patients on Pentostam) and (50 patients on Metronidazole) and seen weekly for a maximum of 8 weeks. RESULTS: Patients treated with Pentostam were significantly associated with a higher complete response rate than patients treated with Metronidazole (P<0.001). Complications of treatment were significantly detected among patients treated with Pentostam (P<0.001). Pain at injection site was significantly perceived as severe among patients treated with Pentostam (P<0.001). CONCLUSIONS: Pentostam solution has a higher efficacy in the treatment of cutaneous leishmaniasis than Metronidazole solution but with higher rates of complications and pain at injection site.

This prospective study was conducted at the Fertility centre in AL-Najaf Al-Ashraf city over a period of one year. The results of this study showed that the mean value and range of the age in the studied groups were (29.71±6.62) (18-45year) while the mean value for BMI was (27.70±4.05) Kg/m 2 , ranging between (19-35.7). The mean duration of infertility was (8.40±4.16), ranged between 2-18years. Quite a large percent, i.e. 86.7% of the subjects had a history of primary subfertility. Normal range values were documented for Basal Hormonal Levels. While peak E 2 was within normal values range, but E2 on CD2 showed higher significance as found in the (non PCO) group. It was found that both the follicular & blood serum AZA was reportedly higher among women with (Non-PCO) of infertility than their counterparts but without any significant difference. Also, the peak means value for follicular AZA in subjects reporting with non PCO group came around 10.29 IU/L, while that for ovulatory cause followed along. The results of present study conclude that the AZA levels (both follicular & blood serum) may be used as one important marker of fecundity in cases of IVF/ICSI procedural candidates to increase successful pregnancy rates and reduce cancellation cycles. Infertile women must be treated for the clinical condition before starting ICSI procedure for successful ICSI outcomes. Thus, even remotest immune activation is detected by blood serum & follicular AZA and treated thoroughly afterwards, may affect ICSI outcome positively. © 2018 Pharmascope Publications.

We demonstrate that the thermoelectric performance of graphene nanoconstrictions can be significantly enhanced by the presence of stable radical adsorbates, because radical molecules adsorbed on the graphene nanoconstrictions create singly-occupied orbitals in the vicinity of Fermi energy. This in turn leads to sharp features in their transmission functions close to Fermi energy, which increases the electrical conductance and Seebeck coefficient of the nanoconstrictions. This is a generic feature of radical adsorbates and can be employed in the design of new thermoelectric devices and materials. © 2018 The Royal Society of Chemistry. | Royal Society of Chemistry | 20403364 | |

Normally, molecular wires become less conductive with increasing length. Here, we report a series of fused porphyrin oligomers for which the conductance increases substantially with length by >10-fold at a bias of 0.7 V. This exceptional behavior can be attributed to the rapid decrease of the HOMO-LUMO gap with the length of fused porphyrins. In contrast, for butadiyne-linked porphyrin oligomers with moderate inter-ring coupling, a normal conductance decrease with length is found for all bias voltages explored (±1 V), although the attenuation factor (β) decreases from ca. 2 nm-1 at low bias to <1 nm-1 at 0.9 V, highlighting that β is not an intrinsic molecular property. Further theoretical analysis using density functional theory underlines the role of intersite coupling and indicates that this large increase in conductance with length at increasing voltages can be generalized to other molecular oligomers.

One Hundred and twenty samples of white soft cheese collected from different areas in Thi-Qargovernorate.The objective of this study was to isolate Staphylococcus aureus,Escherichia coli, Salmonella spp from samples of soft white cheeses obtained from different areas in Thi-Qar governorate, and to determine their antibiotic susceptibility patterns.A total of 120 soft white cheeses samples were collected and screened for the presence of S. aureus Escherichia coli, Salmonella spp. Gram staining, oxidase, catalase, haemolysis and coagulase tests were employed for bacterial identification.All the samples were contaminated with S. aureus,Escherichia coli, Salmonella spp. A total of 30,28,30 S. aureus,Escherichia coli, Salmonella spp isolates were obtained during this study. The levels of contamination with S. aureus were higher in soft white cheese obtained at Thi-Qar area farms (25%, 23.33% and 18.33) respectively. A large percentage of the S. aureus isolates (25.6% and 23.0%) were from Nasiriyah and Batha. All strains were resistant to (10 g), Ampicillin (AP) (10 g), Amoxicillin-Clavulanic acid (AC) (30 g),amikacin (30 g), Erythromycin (E) (15 g), tetracycline (30 grespectively.From the results of this study, it could conclude that the lack ofstandardized method for production and keeping of soft white cheese inThi-Qargovernorate had resulted in the significant variations noticed in the differentquality characteristics of the cheese samples. The high microbial contentof the soft white cheese samples reflects the poor general hygieneconditions during production and storage of milk and cheese, lack ofrefrigeration and absence of steps such as heat treatment to eliminatemicroorganisms. The most alarming trend detected in thisstudy was the determination of antibiotic resistant Staphylococcus aureus,Salmonellaspp.and E. coli. © 2018, Advanced Scientific Research.

Three different sources for microwave absorbers were used to identify the effect of microwave absorber on the product yield from microwave pyrolysis of oily sludge. These absorbers are namely, coconut activated carbon (CAC), palm kernel shell activated carbon (PKSAC) and petroleum coke. The microwave absorbers were added to elevate the temperature of pyrolysis reaction in a nitrogen atmosphere using a modified microwave household reactor. The process included identifying the effect of microwave absorber concentration, and initial moisture content at an optimum sweep gas flow rate on the product yield. The results demonstrated that the addition of CAC, PKSAC and petroleum coke improved the heating rate by shortening the drying process. The results showed that the addition CAC during microwave pyrolysis of oily sludge resulted in the higher gas product distribution compared to other types of absorbers. The results revealed that the addition of 10% of the CAC can pyrolyze oily sludge at a nitrogen gas flow rate of 200 mL/min. At this condition, ~65 wt% of gas was produced for all moisture content of oily sludge samples (4%, 40% and 75%). As well as, this treatment method shortened drying time of oily sludge to 30 minutes.

Advanced kidney disease and renal replacement therapy lead to several metabolic and nutritional derangements, which can be termed as protein-energy wasting of chronic kidney disease. Despite the importance of nutrition in hemodialysis patients, studies have shown insufficient awareness about proper nutrition in these patients. Studies also found positive clinical results and knowledge of nutrition education in hemodialysis patients. A quasi experimental study design is carried out at AL-Hussein Teaching Hospital in AL-Nasiriyah City, from 4th December, 2017 to 9th of July, 2018. A non-probability (Purposive sample) of (80) patients on maintenance hemodialysis patients divided into two group: (40) patients as control group and (40) patients as study group. The data were collected through the use of questionnaire designed by researcher, which consists of three parts (1) sociodemographic data form (2) medical sheet information, and (3) main domains of an education program, by direct interview technique with the patients. Reliability of the questionnaire is determined through a pilot study and the validity through a panel of experts.

Using DFT method, which employed in the Quantum espresso package, to calculate the electronic band structure, band gap, density of states (DOS), total, kinetic, and electrostatic energies. In the pristine case, there are large electronic band gaps, which make all SWBNNTs have insulator behaviors. Also, total, kinetic energies are reduced with increasing the diameter of the tube, but the opposite behavior with the electrostatic energy. By substituting one B atom with single Li impurity, the electronic band gap is reduced. This impurity also changed the shape and reduced the value of the DOS, which confirmed all the obtained results in this report. Similarly, the values of all the above energies are decreased, which make the structure unstable and more reactive. The significant result in this work is that addition of only one lithium atom in the unit cell of SWBNNTs can take the Fermi level down so significantly and result in insulating to semiconducting phase transition. When we replaced one N atom with one Li impurity, all these energies are dependent on the diameter, so the values of energies are reduced with this impurity. The behaviors of these SWBNNTs are altered to P-type. This impurity is converted these SWBNNTs from an insulator to a semimetal state with zero electronic band gap and changing the shape and value of the DOS, which is very important in various applications. © 2018 Elsevier B.V. | Elsevier B.V. | 3682048 | |

We used the DFT method, which implemented in the Quantum espresso package, to calculate the electronic band structure, band gap, density of states (DOS), total energy, and chemical potential. In the pristine case, the BL structure of both WS2 (Tungsten disulfide) and MoS2 (Molybdenum disulfide) showed indirect electronic bandgap of 1.37 eV and 1.26 eV, respectively. A semimetal behavior with a zero-band gap was detected with (B, C, and N)-doped MoS2 and (B and N)-doped WS2 while a direct band gap of ∼0.1eV was revealed in the case of C-doped WS2. The electronic DOS for the BL WS2 and MoS2 were also calculated in the present of B, C, and N impurities. These impurities changed the shape and reduced the value of the DOS, which confirmed all the obtained results in this report.

It has high incidence all over the world. It has many complications such as peripheral neuropathy, cardiac and renal problems and retinopathy, but the diabetic retinopathy considers one of the major problems, which causes retinal damage and leading blindness. Unless we avoid the danger of rapid diagnosis and accurate continuity to monitor any developments that may occur. In addition, distinguish them from other diseases that may affect the eye and which occur for other reasons. Therefore, it is necessary for ophthalmologists to accurately diagnose this disease in order to avoid any error may occur. In this paper, we suggest an algorithm for retinopathy diseases diagnosis to help doctors diagnose diabetes mellitus and distinguish between the health's conditions from the infected condition. The algorithm based on two stages; the first Stage, depends on converting the image to grayscale and improving the contrast of the image using the Contrast Limited Adaptive Histogram Equalization (CLAHE). Then analysis the image by using the Grey Level Co-occurrence Matrix (GLCM) to extraction the image features. The second stage extracting the qualities from the color image by converting (RGB) color space in to (HSV) color space and using color moment algorithm and extract the feature based on color. The features extracted from Qualities gave strong results. The features will be to Neural Network, which enables us to diagnose the cases of, normal and abnormal with high accuracy; our algorithm accuracy is 97%.

There are two types of Breast Cancer; Benign breast cancer and Malignant breast cancer. benign state is poor growing, rarely distributed to other areas of body and also have well-defined edges. Alternatively, Malignant point out has inclination to expand faster which is life intimidating. So, classification of the two state is essential for proper medical diagnosis of a breasts cancer patient. In this paper we suggest a new algorithm to diagnosis the Benign and Malignant cancer where each one (Benign and Malignant) has two types; Begin has two types of tumor adenosis and phyllodes_tumor,while Malignant has two types also ductal_carcinoma and papillary_carcinoma. In this paper we proposed algorithm for diagnosis the Breast cancer where our algorithm has two parts where the first part contain from four steps; the first step is pre-processing step, the second step is for image analysis which used wavelet transform to analysis the images and the third step to extract benefit features which used the results from the wavelet transform to obtain most important numbers of features by using standard division and the fourth step is to know wither the image is Benign or Malignant by using Fuzzy logic to know the two types (Benign or Malignant). The second part is contain the classified image (Benign or Malignant from first part) this part is for classify the other types of Benign (tumor adenosis and phyllodes_tumor) and Malignant (ductal_carcinoma and papillary_carcinoma), in this part we analysis the images by using GLCM after calculate watershed for the image to know the types of benign. For the Malignant we calculate the colour moment (HSV) then calculate standard deviation and mean to extract the features of each types of cancer, where these features will be as input for fuzzy logic to give the final decision for two types of Begin (adenosis and phyllodes_tumor) and two types of Malignant (ductal_carcinoma and papillary_carcinoma), the results accuracy from our algorithm are 98 %. By using the data base from http://web.inf.ufpr.br/vr/breast-cancer-database, which contain more than 7000 images.The suggested knowledge-based system can be utilized as a professional medical decision support system to aid doctors in the healthcare practice. © 2005 – ongoing JATIT & LLS. | Little Lion Scientific | 19928645 | |

The blocks of data are transformed into encrypted data blocks of identical size using a shared session key. A common feature of some modes of block cipher, such as Cipher Block Chaining mode (CBC), Cipher Feedback mode (CFB), Output Feedback mode (OFB), is the sequential processing. The ciphering process of a block cannot begin until the processing of the preceding block is completed. This feature does not make full use of the processing power in multiple processor systems. In this paper, we proposed a Parallel Block Cipher (PBC) mode, in which blocks of cipher can be processed in parallel. Results of speed performance tests of the PBC mode using various settings are presented and compared with the standard CBC mode. The PBC mode was shown to save 60% of execution time when compared with the CBC mode. Furthermore, the hash value of the data file might be utilized to provide integrity check in addition to encryption using AES128. As a result, the PBC mode has a better speed performance on top of the confidentiality and security provided by the CBC mode. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

For the κ - μ shadowed, a novel simple exact closed-form analytic expression for the probability density function (PDF) and the cumulative distribution function (CDF) are introduced by assuming the fading parameters are integer numbers. To this end, the detection performance metrics, namely, the average detection probability and the average area under the receiver operating characteristics curve (AUC) which are used in the analysis of energy detection and the effective rate and the effective rate are derived.

These soluble metallopolymers were formed spontaneously by reaction of an organic ligand (C34+ or C24+) with one molar equivalent of metal ions. The C34+ and C24+ ligands incorporate two chelating terpyridine groups bridged by a redox responsive hinge featuring two viologen units (viologen=N,N′-dialkyl-4,4′-bipyridinium) linked either with propyl (C34+) or ethyl (C24+) chains. The viologen units in the polymer chains were reduced (1 e− per viologen group) either by bulk electrolysis or by visible-light irradiation carried out in the presence of a photosensitizer. The 1 e− reduction of the viologen units in the MC24+ polymers induced a slight decrease in the viscosity of the solutions due to a modification of the overall charge carried by the metallopolymers. In strong contrast, reduction of coordination polymers involving propyl linkers (MC34+) led to a remarkable increase (≈+400 %) in observed viscosity. This reversible effect was attributed to a folding of the polymer chains triggered by π-dimerization of the photo-generated viologen cation radicals. © 2018 Wiley-VCH Verlag GmbH & Co.

This method provides accurate approximations for the velocity and the pressure variables. General polygonal or polyhedral partitions can be applied in this method. The finite element space which is made up of piecewise polynomials is easy to be constructed. These advantages make the weak Galerkin finite element method efficient and highly flexible. Optimal rates of convergence for the velocity function u and the pressure function p are established in corresponding norms. In addition, the convergence rates are independent of the viscosity parameter ϵ.

The surface characterization of PPAC was achieved using Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), N2 adsorption/ desorption, X-Ray Diffraction (XRD), and the point of zero charge (pHPZC) method. It was found that PPAC a large surface area and total pore volume corresponded to 1280.45 m²/g and 1.343 cm3/g, respectively. The adsorption properties of PPAC with methylene blue (MB) was conducted at different adsorbent dose (0.23 g/L), solution pH (311), initial dye concentrations (50 mg/L400 mg/L), contact time (0135 min) using batch mode operation. The kinetic uptake profiles are well described by the pseudo-second-order model, while the Langmuir model describes the adsorption behaviour at equilibrium. The maximum adsorption capacity of PPAC with methylene blue was 384.61 mg/g at 303 K. Various thermodynamic parameters such as standard enthalpy (∆H°), standard entropy (∆S°) and standard free energy (∆G°) showed that the adsorption of MB onto PPAC was favourable and endothermic in nature. © 2018 Desalination Publications.

It is a piece of the procedure of basic outline, tremor designing or auxiliary appraisal the Portable building can possibly 'wave' forward and backward amid a quake (or even a serious breeze storm). This is known as the 'basic mode', and is the most minimal recurrence of movable building reaction. Most Portable building structures have higher methods of reaction, which are interestingly enacted amid tremors. For every mode, a reaction is perused from the outline range, in view of the modular recurrence and the modular mass, and they are then consolidated to give a gauge of the aggregate reaction of the structure. In this we need to compute the size of powers every which way and after that see the impacts on the building. This approach characterizes a progression of powers following up on a movable working to speak to the impact of quake ground movement, commonly characterized by a seismic plan reaction range. The relevance of this technique is stretched out in numerous Portable construction standards by applying elements to represent higher movable structures with some higher modes, and for low levels of bending. To represent impacts because of "yielding" of the structure, numerous codes apply adjustment factors that diminish the power situation, the results of this study point out the significance of vibrations caused by shaking in construction of engineering structures as well as the appropriate performance of a TMD and MR in reducing oscillations in Movable buildings. © IAEME Publication | IAEME Publication | 9766308 | |

This study employs the OA to determine representative sample points from the original EEG data and then applies periodogram (PD), autoregressive (AR), and the mixture of PD and AR to extract the discriminative features from each OA sample group. The obtained feature sets are evaluated by three popular machine learning methods: support vector machine (SVM), quadratic discriminant analysis (QDA), and k-nearest neighbour (k- NN). Several output coding approaches of the SVM classifier are tested for selecting the best feature sets. This scheme was implemented on a benchmark epileptic EEG database for evaluation and also compared with existing methods. The experimental results show that the OA_AR feature set yields better performances by the SVM with an overall accuracy of 100%, and outperforms the state-of-the-art works with a 14.1% improvement. Thus, the findings of this study prove that the proposed OA-based AR scheme has significant potential to extract features from EEG signals. The proposed method will assist experts to automatically analyse a large volume of EEG data and benefit epilepsy research. © The Institution of Engineering and Technology 2018. | Institution of Engineering and Technology | 17519675 | |

The ZSWBNNTs and ASWBNNTs show semiconductor and insulator behaviors, respectively along with a direct bandgap at the Γ point in the pristine cases. The obtained results display that this island is affected and altered to the electronic and thermoelectric properties of all systems. The behaviors of all systems are turning to semiconductor and the electronic band gaps are reduced with the C island which enables to use these doped materials in various applications. Meanwhile, the thermoelectric parameters, such as Seebeck coefficient (S), thermoelectric figure of Merit (ZT), phonon thermal conductance (Kph), electrons thermal conductance (Ke), and thermal conductivity of all systems are calculated and studied with and without the C island. The results show that all these thermoelectric properties are related directly to the diameter of the ZSWBNNTs and ASWBNNTs. © 2018 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

ANN is a powerful tool capable of determining the relationship between the desired input and output data while PSO was used as a robust population-based search algorithm to optimize the performance of the ANN model. Specifically, it was used to determine the optimum number of neurons in the hidden layer and the best value of the learning rate of the ANN model. The optimization method includes minimizing the fitness function mean absolute error that was found to be 0.0176. The PSO algorithm suggested an optimum number of neurons in the hidden layer as 15 and a learning rate of 0.761 these consequently used to construct the ANN model. After constructing the hybrid PSO–ANN model, the performance of the intelligent system was examined by determining the regression coefficient (R2) for estimating the experimental values of glucose and xylose and compared to the results from a response surface methodology (RSM) model. The results of R2 of the hybrid PSO–ANN model for glucose and xylose were 0.9939 and 0.9479, respectively, while the RSM model results for the same sugars were 0.8901 and 0.8439. This analysis reveals that the hybrid PSO–ANN model offers a higher degree of accuracy in comparison with the more commonly used RSM model. © 2016, The Natural Computing Applications Forum. | Springer London | 9410643 | |

The experimental investigation was conducted using a Perspex column with an internal diameter of 10 cm and 100 cm height. Liquid pentane at its saturation temperature and warm water were used in the dispersed phase and continuous phase respectively. Various dispersed phase flow rates (10,15and20L/h) and continuous phase flow rates (10,20,30and40L/h) were tested using three different sparger configurations (7,19and36nozzles) and two different nozzle diameters (1 and 1.25 mm). The results showed that the temperature of the continuous phase decreased with the height of the heat exchanger from its inlet at the top towards its outlet at the bottom. This behaviour was entirely opposite to the dispersed phase that flows counter currently with the continuous phase in the heat exchanger. For the same sparger and constant continuous phase flow rate (Qc), the outlet temperature of the continuous phase was inversely affected by the dispersed phase flow rate (Qd); while decreasing the nozzle numbers in the sparger led to a decrease in the outlet temperature of the continuous phase. Furthermore, the initial temperature of the continuous phase in terms of the Jakobs number (Ja) was found to have a significant positive impact on outlet temperature: the higher the Ja, the higher the outlet temperature. The analytical model had an acceptable agreement with the experimental measurements. © 2018 Elsevier Ltd | Elsevier Ltd | 13594311 | |

For this reason, the energy gaps, frontier orbital (HOMO, and LUMO) distributions, total energies, Fermi level energies, work functions and maximum wavelength absorption, vertical absorption energies, and oscillator strengths have been investigated and discussed. The structures of phenanthrene-1,3,4-thiadiazoles oligomers are expanded from 1 to 10 thiadiazole monomeric units, to examine the increase of thiadiazole monomeric units on the optoelectronic properties. We observed that increased the number of monomeric units lead to significantly enhance the optoelectronic properties, which caused to decrease the gap energy from 3.69 eV in the structure with one thiadiazole ring just to 2.36 eV with 10 units. These changes give the shift of maximum absorption wavelengths from 376 to 578 nm. Consequently, these molecules have main absorption bands within the solar spectrum, to give the best performance for photovoltaic and organic solar cells devices. © 2018, Pleiades Publishing, Ltd. | Pleiades Publishing | 19907931 | |

The shaped metal deposition method would be an alternative way to traditional manufacturing methods, especially for complex featured and large-scale solid parts manufacturing, and it is particularly used for aerospace structural components, manufacturing, and repairing of die/molds and middle-sized dense parts. This article presents the designing, constructing, and controlling of an additive manufacturing system using tungsten inert gas plus wire–based shaped metal deposition method. The aim of this work is to design and develop tungsten inert gas plus wire–based shaped metal deposition system to be used for fabricating different components directly from computer-aided design data with minimum time consumed in programming and less boring task compared to conventional robotic systems. So, this article covers the important design steps from computer-aided design data to the final deposited part. The developed additive system is capable of producing near-net-shaped components of sizes not exceeding 400 mm in three-dimensional directly from computer-aided design drawing. The results showed that the developed system succeeded to produce near-net-shaped parts for various features of SS308LSi components. Additionally, workshop tests have been conducted in order to verify the capability and reliability of the developed additive manufacturing system. The developed system is also capable of reducing the buy-to-fly ratio from 5 to 2 by reducing waste material from 1717 to 268 g for the sample components. © IMechE 2016. | SAGE Publications Ltd | 9544054 | |

The success of fire service depends mainly on the speed of the fire truck reaching the scene and the performance on field to reduce losses to a minimum ratio. The objective of study is utilizing the applications of GIS to assess the efficiency of spatial coverage of the fire service in Nasiriyah city and spelling out the necessary measures to increase coverage at the short and long term. The coverage is first evaluated according to the service ranges currently applied by the government departments responsible for the fire service. The obtained results are compared to the coverage based on service radius .The study suggests the service polygon method to determine areas where the fire service can reach in (4 minutes) or less. The main conclusions of the study is that the assessment of the coverage using a radius of service equal to (2.5 km) corresponds to the characteristics of the road network in the study area, but the findings of coverage using the suggested service polygon method is more accurate and closer to reality. The number of fire stations available within the area of study is sufficient at the current time, but poor distribution has provided typical coverage for only 60% of the areas in need of fire service. © IAEME Publication. | IAEME Publication | 9766308 | |

Male rabbits were divided into four groups of six animals. The intact rabbits in the first group served as a negative control. The second group served as a positive control (hypercholesterolemic rabbits). Over a 4-week period, hypercholesterolemic rabbits in the third group received a low dose of alkaloid extract (33 mg/kg), and the hypercholesterolemic rabbits in the fourth group received a high dose (66 mg/kg). The results revealed that both doses of alkaloid extract significantly decreased levels of cholesterol, triglycerides, low-density lipoproteins (LDL), and very low-density lipoproteins (VLDL) when compared to the control group, whereas the high-density lipoproteins (HDL) increased significantly compared to the control group. The active compounds in the alkaloid extract were identified using GC-mass. The most abundant compounds found in the extract were 1-(+)-ascorbic acid 2,6-dihexadecanoate, 9,12-octadecadienoic acid (Z, Z)-, hexadecanoic acid, 2-hydroxy-1- (hydroxymethyl) ethyl ester, and gamolenic acid. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature. | Springer Verlag | 9441344 | |

In today’s era of technology, M-Learning (ML) system has become an important component of Information and Communication Technology provided by educational institutions such as universities to facilitate all the transactions between institutions and their students or lecturers. This system has gained the popularity in developed and developing countries alike. Despite the known benefits of ML to the education community, usage of ML services among students in the developing countries, especially in Iraq, is still low. Additionally, there has not been empirical study on the continuous usage of ML services in developing countries such as Iraq. The primary objective of this study is to determine the contributing factors for continuous usage of ML services among students in a higher education of Iraq. Moreover, the study used quantitative approach by distributing 600 questionnaires to respondents in the public universities of Iraq. Besides that, the collected data was analysed using a Structural Equation Model. The findings showed that information quality construct has a large effect on user satisfaction than service quality and compatibility constructs. © 2005 - ongoing JATIT & LLS. | Little Lion Scientific | 19928645 | |

Different particle sizes were considered, i.e. diameters between 1–1.4, 2–2.8 and 4–5.6 mm. The microstructures of EG-MSF were investigated by optical and scanning electron microscopy and the grain size of the aluminium alloy was found to increase with EG particle size. Uni-axial compression testing of EG-MSF indicated that its mechanical properties depend both on foam density and particle size.

OFDM framework indicates numerous positive properties, for example, high phantom effectiveness, strength to channel blurring and insusceptibility to drive impedance. The fundamental weakness of OFDM is the high time-area crest to-normal power proportion (PAPR) that cutoff point’s transmitter control effectiveness. Something else, OFDM flag might be misshaped by the nonlinear conduct of the powerful intensifier (HPA) at the transmitter. The transmitter can lessen PAPR by misshaping the information bearers or by adding energy to the free transporters. This paper investigates the capacity of Dummy Sequence Insertion (DSI) calculation to diminish PAPR in remote neighborhood (WLAN)/OFDM framework. The joining of DSI on this framework is performed by estimating the PAPR at the yield of the IFFT (Inverse Fast Fourier Transform) in the wake of including a 6-bit succession at the spurious sub-channels information sources and settle on a choice to transmit the information if the PAPR for this information grouping under a predetermined edge. Not at all like a large portion of the information contortion have calculations utilized for PAPR lessening techniques, did the low unpredictability DSI strategy not required any sort of side data. Reenactment comes about are exhibited for a system show composed by WLAN 802.11a standard utilizing MATLAB as a scientific reproduction programming device. The system demonstrate has been reenacted in Additive White Gaussian Noise (AWGN) channel condition to research the conduct of PAPR and Bit-Error Rate (BER) execution. The reenactment comes about demonstrate that the information bending strategy in view of DSI lessens PAPR down to 4 dB contrasted with customary OFDM framework, and down to 2 dB contrasted and cutting method for the same BER execution. © IAEME Publication. | IAEME Publication | 9766340 | |

Different values of twisting ratio (y/w) of 2, 4 and 6 with volume concentration (ϕ) of 0.5% and 4 % are investigated under Reynolds number range of 5000 to 35000. The object of this project is to augment the transfer of heat in a tube by employing the combined influence of double twisting tape with nano fluid. The Navier - Stockes and energy equations as well to the turbulence model are desired for modeling this physical problem. ANSYS Fluent code is utilized to gain the results. The numerical consequence explained that the Nusselt number (Nu), friction factor (f), and overall thermal performance factor raises as twisting ratio decreases. The results also display that the twin twisting tape more effective than a plain tube for heat transfer augmentation. This increase is improved with increasing volume concentration. © 2006-2018 Asian Research Publishing Network (ARPN). | Asian Research Publishing Network | 18196608 | |

Al2o3-water is adopted as the nano fluid. The whirling motion is tested with clockwise and counter twin twisting tape. The investigation has been conducted for Reynolds number range from 5000 to 35000 while the twist ratio has the values 2,4 and 6 respectively. Two values of nano fluid volume concentration is examined as 0.5% and 4% respectively. The research is aim to promote the heat transfer enhancement by means of the combined mechanism of twin twisted tape and nano fluid. A FLUENT ANSYS 17 commercial code is used for problem designing, formulation and getting the results. The obtained results show that the twin twist is most active than the single twist for heat transmit improvement. This increase is enhanced as the volume concentration increases. In addition, a counter clockwise twisting tape offered better thermal performance than clockwise twisting. The numerical consequence revealed that, the Nusselt number, friction factor, and overall performance factor increase as twist ratio decreases. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The conversion of light into plasmons is a possible way to overcome this problem. Plasmon's wavelengths are much shorter than that of light which enables the propagation of signals in small size components. In this paper, a 3D simulation of surface plasmon polariton (SPP) excitation is performed. The Finite integration technique was used to solve Maxwell's equations in the dielectric-metal interface. The results show how the surface plasmon polariton was generated at the grating assisted dielectric-metal interface. SPP is a good candidate for signal confinement in small size optoelectronics which allow high density optical integrated circuits in all optical networks. © 2018 The Authors | Elsevier B.V. | 22113797 | |

The people’s perception of infertility varies from culture to culture. So this work amid to determine the prevalence and pattern of endocrinological abnormalities and semen parameters in patients investigated for male infertility in our environment, and any associated between semen’s and hormones’ results. This work included 89 infertility men and 11 healthy as control group. Their age was ranged between 20-50 years old. The volume, concentration and movement of seminal fluid patterns were examined. Then patients were divided to four groups: Azospermia, Oligospermia, and Normospermia poor movement. Follicle-stimulating hormone FSH, luteinizing hormone LH, Prolactin, and Testosterone were determined. The endocrinological diagnosis was done. The highest frequency % of cases was normospermia with poor movement and the lowest was azospermia. The mean of patients’ age was about 34.5 years. The frequencies% of infertility was significantly higher within 25-40 age group. The semen volume was significantly lower in Azospermia and Oligospermia groups. The normal shape sperm and the sperm concentration were lower in all patients groups. FSH, LH, and prolactin levels increased in Azospermia and Oligospermea groups compared to normospermia and control groups. The highest frequency of cases with high FSH, LH, and Prolactin was in Azospermea, and lowest in normospermia while the frequency of cases with high testosterone frequency was (0) in Azospermea and only (1) in Oligospermea, and Normospermea. In Azospermia and Oligospermia, the significantly highest endocrinological diagnosis was germinal epithelial failure. This study reported the significance of proper endocrinological work-up in evaluating patients with infertility where appropriate because these cases may be identifiable endocrine disorders that may be correctable, and that in our environment, endocrine dysfunction is common cause of male infertility. It also reported the frequencies of different endocrine abnormalities, some of which can be successfully processed. We conclude that hormonal evaluations should be performed in the assessment of infertility in males in our environment. © 2009-2018, JGPT.

The governing equation includes thermal strain induced by web temperature change and assumes viscoelastic material behavior. A closed-form expression for temperature distribution in the moving web is derived, which is utilized to obtain thermal strain. A model for web tension in a multispan roll-to-roll system can be developed using this governing equation. To evaluate the governing equation, measured data from an industrial web process line are compared with data from model simulations. Since the viscoelastic behavior of web materials is affected by the web temperature change, elevated temperature creep, and stress-relaxation experiments are conducted to determine the temperature-dependent viscoelastic parameters of the utilized viscoelastic model. Comparisons of the measured data with model simulation data are presented and discussed. An analysis of the web tension disturbance propagation behavior is also provided to compare transport behavior of elastic and viscoelastic materials.

This method is based on the interaction prediction principle due to a two-level functional hierarchy of calculation is organized in the method, and aimed at increasing their scalability and reducing computational complexity. At the lower level, the routing order is determined, and at the upper level, the link resource is allocated between flows with different classes of service. The numerical example confirms the convergence of the method to optimal solutions for a finite number of iterations. Also due to the use of the interaction prediction principle, the solution of the problem of route recalculation and the order of link resource allocation can be completed at an arbitrary iteration and the resulting solution will be acceptable and satisfy all the conditions and constraints. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

In the present study, the effect of rolling process parameters such as friction coefficient between roller-plate surfaces, roller's speed and diameter has been investigated. An FE simulation was carried out using ABAQUS 6.12 software (Explicit) to investigate the influence of these parameters on roller's force, equivalent plastic strain (PEEQ) and vonMises stresses. The results show the roller diameter has a significant effect on the effective friction coefficient (EFC) than roller speed, meanwhile, the increasing of roller diameter leads to decrease the rolling process time. Moreover, the vonMises stresses increase throughout the rolling process until reach a certain value then slightly decrease and remain almost in the extent of this value even the finished of the process. Also the equivalent plastic strain (PEEQ) has inverse relation with the roller speed. © IJENS. | International Journals of Engineering and Sciences Publisher | 22272771 | |

In this paper, an attempt is made to design a new DoA index. We applied a statistical model and spectral graph wavelet transform (SGWT) to monitor the DoA. The de-noised electroencephalography (EEG) signals are partitioned into segments using a window technique. The window size is determined empirically, then each EEG segment is divided into sub-blocks to make the signal quasi stationary. 10 statistical characteristics are extracted from each sub-block. As a result, a vector of statistical characteristics is pulled out from each segment. Each vector of the features is then mapped as a weighted graph and spectral graph wavelet transform is performed. The total energy of wavelet coefficients at different scales is tested. The energy of wavelet coefficients at scale 3 is selected to form a SGWTDoA function. The SGWTDoA is evaluated using an anesthesia EEG recordings and the bispectral (BIS) from 22 subjects. The Bland-Altman, regression, Q-Q plot and Pearson correlation are used to verify the agreement between the SGWTDoA and the BIS. The experimental results demonstrate that the SGWTDoA has the ability to estimate the DoA accurately. The SGWTDoA is also compared and tested with the BIS in the case of poor signal quality. Our findings show that, the SGWTDoA can reflect the transition from unconsciousness to consciousness efficiently even for a poor signal while the BIS fails to display the DoA values on the monitor. © 2018 Elsevier Ltd | Elsevier B.V. | 2632241 | |

This study explored the utilization of three methods of modification of AC produced from coconut shell by treating it with nitric acid (HNO3), potassium permanganate (KMnO4) and heating at 600°C to improve the adsorption capacity. The AC can remove multi-pollutants in the filtration process which was used to treat landfill leachate. The water quality parameters such as pH, TSS, Ammonia-Nitrogen and a few heavy metals were considered in the present study. Results showed that the removal of these parameters was proportional with the increase of contact time and the bed depth of AC. The isotherm analysis of the adsorption of modified AC showed the best Removal Efficiency (RE) can be achieved when AC treated with KMnO4 for NH3-N, zinc, TSS and sulphide. The morphology of the AC was studied through Scanning Electron Microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDX) pattern analysis and Fourier Transform Infrared (FTIR) analysis. It was found that various types of oxygen functional groups were introduced onto the surface of coconut shell derived AC through oxidation using HNO3. FTIR was used to characterize the surface oxygen functional groups. The surface functional groups such as N-H and C-H stretching played a significant role in heavy metals adsorption. Hence, it can be concluded that the hybrid technique by using electrolysis process with AC adsorption be an effective way to remove the suspended solids and heavy metals from landfill leachate and thus able to reduce environmental pollution. © 2018, Korean Society of Civil Engineers. | Springer Verlag | 12267988 | |

The objectives of this study were to assess the bioavailability and transfer potential of various TMs present in water and sediments in a reservoir receiving landfill leachates. An active biomonitoring approach was adopted consisting of exposing naive laboratory organisms in cages deployed in the field. Aquatic insects such as Chironomus riparius larvae are good candidates since they represent key organisms in the trophic functioning of aquatic ecosystems. The results show that water, suspended particles, and sediments were significantly contaminated by various TMs (As, Cd, Cu, Ni, Pb, and Zn). Their contribution to the transfer of TMs depends, however, on the specific element considered, e.g., Cd in sediments or Pb in both suspended particles and sediments. The internal fate of TMs was investigated according to their fractionation between an insoluble and a cytosolic fraction. This approach revealed different detoxification strategies capable of preventing the induction of deleterious effects at the individual scale. However, the accumulation of several TMs in C. riparius larvae tissues may also represent a significant load potentially transferable to higher trophic levels. © 2017, Springer-Verlag Berlin Heidelberg. | Springer Verlag | 9441344 | |

Hence, the accuracy of detection and matching fingerprint plays an important role in many research works. Many fingerprints sample are degraded through such other transformations. Therefore, there is a need to find a method that able to detect and match fingerprints sample over all other circumstances and give high accuracy rate. There are two approaches are commonly used, minutiae based and image based approach, minutia approach faced several problems when fingerprint samples are degraded or rotated which lead to poor performance result, image-based approach is seem that its very robust against such other degradation issues. In this paper, we proposed a novel modification to one of the most robust algorithms that used to extract the interest points, called SURF. These points also called feature are later used for matching process after eliminating outlier sets. The proposed system is tested on FVC2002 DB1, and FVC2004 DB2 according to set of performance evaluation metrics such as FAR, FRR, SMR, EER and accuracy, which shows our proposed system can successfully find matching between one fingerprint and other one (1:1) matching, as well as (1:M) matching when more than one fingerprint images may have related to the query image. © 2005 – ongoing JATIT & LLS. | Little Lion Scientific | 19928645 | |

Nodes that are near to the sink node consume more energy as all biomedical packets are aggregated through these nodes when communicated to the sink node. Each biosensor node in a wireless body sensor network (WBSN) such as electrocardiogram (ECG), should provide accurate biomedical data due to the paramount importance of patient information. We propose a technique to minimize energy consumed by biosensor nodes in the bottleneck zone for WBSNs, which applies the coordinated duty cycle algorithm (CDCA) to all nodes in the bottleneck zone. Superframe order selection in CDCA is based on real traffic and the priority of the nodes in the WBSN. Furthermore, we use a special case of network coding, called random linear network coding (RLNC), to encode the biomedical packets to improve reliability through calculating the probability of successful reception at the sink node. It can be concluded that CDCA outperforms other algorithms in terms of energy saving as it achieves energy savings for most biosensor nodes in WBSNs. RLNC employs relay nodes to achieve the required level of reliability in WBSNs and to guarantee that the biomedical data is delivered correctly to the sink node. © 2018 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

So far, there has been no research on burnout among primary school teachers in Basrah, Iraq. Aim: We aimed to determine the prevalence and predisposing factors of self-reported burnout among primary school teachers in Basrah. Methods: This was a cross-sectional study in 32 governmental primary schools during November 2014–February 2015. A self-administered questionnaire was used to collect sociodemographic and work-related data using the Oldenburg Burnout Inventory. Results: Of 800 questionnaires distributed, 706 (88.3%) were completed; 58.4% were from women. The prevalence of burnout was 24.5% (95% CI: 21.5–27.8). A statistically significant association was found between burnout and age, sex and marital status. Work-related factors that showed significant association with burnout were: work overload, problems related to career advancement, high number of students per class and student misbehaviour. Conclusion: Burnout is an important health problem among primary school teachers in Basrah. A number of risk factors, particularly those related to work, are amenable to modification since they are related to the education policy. © 2018, World Health Organization.

As a result, the use of AM to produce Al matrix Composites (AMCs) which have superior properties to their castable counterparts is an emerging area of research. In this paper, micro TiB2 particles were decorated to the surface of larger AlSi10Mg powder particles to create feedstocks through the ‘satelliting’ method. TiB2/AlSi10Mg composites were then successfully fabricated by Direct Metal Deposition (DMD) with a uniform distribution of the reinforcing TiB2 particles observed. Results show that macro agglomerations of TiB2 particles decrease significantly with decreasing traverse speed and TiB2 content. Porosity is also shown to decrease markedly with increasing traverse speed for this material feedstock. The hardness of deposits is shown to increase with addition of TiB2 content, which implies improvement of material strength. © 2017 | Elsevier B.V. | 0167577X | |

X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray spectrometry (EDS), and atomic force microscopy (AFM) were carried out to characterize the synthesized powder. XRD results showed that material obtained at calcination temperature (1000 °C) is a HAp according to (ICDD 00-024-0033) pattern in a 1.6557 Ca/P molar ratio and the chemical composition is Ca5(PO4)3(OH). The FTIR and Raman spectra confirm the formation of HAp by the presence of peaks corresponding to (PO4)3− and OH− groups, which are of great importance in HAp molecules.

The benzene rings were threaded by a magnetic flux that changes over time. The quantum interference effect was considered as the basic idea in the rectification action, the para and meta configurations were investigated. All the calculations are performed by using steady-state theoretical model, which is based on the time-dependent Hamiltonian model. The electrical conductance and the electric current are considered as DC output signals of half-wave and full-wave molecular rectifiers.

Researchers have attempted to overcome this by thermal management in the process and through the formulation of new alloys. A novel material preparation method “satelliting” was used in combination with DMD to improve the microstructure of the deposited alloys. Three feedstocks of Ti-15Mo, including a satellited feedstock, a blend of Ti/Mo (150 μm) and blended Ti/Mo (3 μm), were prepared and used for DMD of Ti-15Mo. Fine equiaxed grains and near-equiaxed grains distributed uniformly were found in the deposited sample from satellited feedstock, while the samples from blended Ti/Mo (150 μm) and Ti/Mo (3 μm) are dominated by larger near-equiaxed grains and epitaxial columnar grains, respectively. The effect of the nucleation was verified by combinatory analysis of unmelted Mo particles. This demonstrates a new route to the manufacture of components through DMD which produces applicable microstructures directly from the build. © 2017 Elsevier B.V. | Elsevier B.V. | 0167577X | |

Two scenarios are investigated; in the first scenario, it is assumed that the system employs distance-based fractional power control with no multicell coordination. For the second scenario, we assume the system implements multicell coordinated beamforming so as to cancel inter-cell interference. For both scenarios, the BSs are assumed to randomly uniformly distributed in the area according to Poisson point process. Using tools from stochastic geometry, tractable, analytical expressions for coverage probability and effective capacity are derived for both scenarios. Numerical results reveal that for a system with stringent delay quality of service (QoS) constraints, i.e. (traffic delay is intolerable), best performance can be achieved by suitably adopting fractional power strategy when transmitting to the users, while constant power allocation performs better than all other power allocation strategies when the delay QoS constraints get loose (tolerable delay). For coverage probability, a fractional power control is better than constant power and channel inversion power strategies for low signal-to-interference plus noise ratio (SINR) thresholds, while the constant power strategy performs better than others in high SINR thresholds. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Solar energy is likely to be the energy of the future and solar ponds, in particular, salinity gradient solar ponds (SGSP), facilitate simple and cost-effective thermal energy collection and storage. In this study; the influence of varying the thicknesses of the zones present in a salinity gradient solar pond on the temperatures of the upper convective zone (UCZ) and the lower convective zone (LCZ) is investigated. The study finds that thickness variation of the zones within the pond has a considerable impact on the temperature of the LCZ while it has a small effect on the temperature of the UCZ. The optimal thicknesses of the UCZ and the non-convective zone (NCZ) have been found to be 0.2 and 2 m respectively. The results also show that the type of application plays a substantial role in determining the depth of the LCZ, and that temperature of this zone varies with the rate of heat extraction. A period of no heat extraction is required to allow the pond to warm up and the length of this period depends on the depth of the LCZ, the type of application coupled with the pond, and the rate of heat extraction. It was found that the SGSP could be deeper with less surface area, and still suitable for applications that require low-grade heat. These findings could form the basis of future studies regarding the performance and financial viability of the overall depth of SGSPs. © 2017 Elsevier Ltd | Elsevier Ltd | 13594311 | |

This paper explores the feasibility of gel solar ponds as a source of renewables, using theoretical evaluation. This could be of critical future utilization in areas such as desalination, where the gel solar pond could in effect be a means to deliver fresh water in the Middle East and other regions where water scarcity is predicted to become an increasingly critical issue to resolve. This study explores all aspects of the gel solar pond's functioning, including optimal thicknesses for its different layers, and explores its strengths and weaknesses. In this study; temperature profiles in the upper convective zone (UCZ) and lower convective zone (LCZ) of a gel pond are investigated. The impact of the thickness of the pond's layers on the temperatures of these zones was also investigated. The cost of the gel pond was calculated and compared with that of the salinity gradient solar pond (SGSP) for a particular application, the multi-effect desalination (MED), which is frequently used to desalinate sea water. The results showed that the gel pond could supply thermal energy to applications requiring low-grade temperatures, and that temperatures in the LCZ of the gel pond could reach values similar to those achieved in the SGSP. Varying the thicknesses of the gel layer and the LCZ affects the temperature of the storage zone. The optimal thickness of the upper water layer and the gel layer was found to be 0.05 and 0.9 m respectively, while the optimal thickness of the storage zone depends on the particular application for which the pond is being used in each case. The results also show that a gel pond normally costs more than a SGSP. This study illustrates that gel solar ponds can offer solutions to some of the challenges posed by the SGSP; however, difficulties relating to cost and labour decrease their potential exploitation. Gel ponds can be seen as a viable alternative to SGSPs only if cheap and environmentally friendly polymers are used to form the gel layer. © 2017 Elsevier Ltd | Elsevier Ltd | 13594311 | |

These different cases (roughened and smooth bottom walls) are considered at various clockwise and anticlockwise rotational speeds, -5 ≤ Ω ≤ 5, and Reynolds numbers of 5000 and 10 000. The top and bottom walls of the lid-driven cavity are differentially heated, whilst the remaining cavity walls are assumed to be stationary and adiabatic. A standard k-ϵ model for the Unsteady Reynolds-Averaged Navier-Stokes equations is used to deal with the turbulent flow. The heat transfer improvement is carefully considered and analysed through the detailed examinations of the flow and thermal fields, the turbulent kinetic energy, the mean velocity profiles, the wall shear stresses, and the local and average Nusselt numbers. It has been concluded that artificial roughness can strongly affect the thermal fields and fluid flow patterns. Ultimately, the heat transfer rate has been dramatically increased by involving the introduced artificial rips. Increasing the cylinder rotational speed or Reynolds number can enhance the heat transfer process, especially when the wall roughness exists. © 2018 Author(s). | American Institute of Physics Inc. | 10706631 | |

Many mechanisms for tuning QE are examined. The first mechanism is doping the QD layer only, which is the case of CdSe, and it gives high QE. The second one is doping the bulk layer in addition to QDs, and it gives low QE but at a wide bandwidth, as in TiO2∕MgZnO QD solar cells.

These ortho substituents lead to two atropisomers, cis and trans, for each compound, which do not interconvert in solution under ambient conditions; even at high temperatures, isomerization takes several hours (half-life 15 h at 140 °C for SAc in C2Cl4D2). All the S2 compounds exhibit two conductance groups, and comparison with a monothiolated (S1) compound shows the higher group arises from a direct Au-porphyrin interaction. The lower conductance group is associated with the S-to-S pathway. When the binding group is SMe, the difference in junction length distribution reflects the difference in S-S distance (0.3 nm) between the two isomers. In the case of SAc, there are no significant differences between the plateau length distributions of the two isomers, and both show maximal stretching distances well exceeding their calculated junction lengths. Contact deformation accounts for part of the extra length, but the results indicate that cis-to-trans conversion takes place in the junction for the cis isomer. The barrier to atropisomerization is lower than the strength of the thiolate Au-S and Au-Au bonds, but higher than that of the Au-SMe bond, which explains why the strain in the junction only induces isomerization in the SAc compound. © 2017 American Chemical Society. | American Chemical Society | 27863 | |

However, despite advances in echnologies and diagnostic methods in the field of andrology, there remains a significant subset of these subfertile men who are classified as having unexplained male infertility. Oxidative stress (OS) is a consequence of an imbalance between the production of reactive oxygen species(ROS) and the body's antioxidant defense mechanisms. Oxidative stress (OS) is a common pathology seen in approximately half of all infertile men. It has been shown that reactive oxygen species (ROS) can lead to deleterious effects on a range of sperm parameters. Vitamins C and E are capable of reducing ROS levels and lipid peroxidation. The aim of study was to determine the level of lipid peroxidation as indicated by malondialdehyde (MDA) and vitamins (C,E) in serum and seminal plasma of unexplained male infertility men compare with fertile men. Serum and seminal plasma MDA was significantly increased in unexplained infertile (smoker and nonsmoker) groups when compared to fertile (smoker and nonsmoker) groups. The antioxidant serum vitamins (C,E) were significantly decreased in unexplained infertile (smoker and nonsmoker) groups when compared to fertile (smoker and nonsmoker) groups. The decrease in antioxidant levels appears to be mainly a consequence of increased oxidative stress. © 2018, Connect Journal. | Connect Journal | 9725075 | |

Building any kind of digital modulators using soc type Field Programmable Gate Array (FPGA), like ZYBO, depends heavily on how the carrier signal got generated since it consumes a lot of utilization recourses. This paper presents a new method of generating sinusoidal carrier signal based on Direct Digital Synthesizer (DDS) concept using small size Look Up Table (LUT). 64 samples of a quarter period of the sine wave signal were stored in a fixed point format in small LUT to generate the carrier at the desire frequency. The paper used Very high speed integrated circuit Hardware Descriptive Language (VHDL) without the help of DSP Builder Tools or XILINX System Generator. The suggested method was tested by building simple modulators like On-Off Keying (OOK) and Amplitude Shift Keying (ASK). Low utilization was achieved as compared to other implementation methods. © 2018, International University of Sarajevo. | International University of Sarajevo | 23034521 | |

It is a method of computing where significantly scalable resources are delivered as services to customers using internet techniques. The task-scheduling in cloud computing system is used for selection of suitable resources for tasks execution by taking some constraints and parameters into consideration. The recent task-scheduling strategies of cloud computing focus on requirements of task resource for processing all tasks without considering the bandwidth, storage and memory. In this paper, we develop task-scheduling approach that aggregate the tasks into groups, which can meet users’ satisfaction. This approach depends on user demand of different resources that have different costs. We compared our approach with the traditional approach. The result proved that our method can significantly reduce the cost of bandwidth, memory and storage under the budget constraint scheduler. © Springer Nature Singapore Pte Ltd. 2018. | Springer | 23673370 | |

The region, which is the subject of the study, consists of group of seasonal valleys; most important among them are Abu Ghar, Qaseir, Sadir, Abu Ghuwair, Abu Hazeer, Al-Hawaimi,, Al- Ashali, Al-Ghanimi and Husam valleys. Most of them were made up of alluvial fans that can be used for agricultural investment, as well as the soils of valleys beds, depressions (playa), and the desert plain. What has currently been invested of them is only small and very limited area, less than) 0.5% (for wheat growing). This study classified the lands of the region into 7 land farms units, based on the qualities of soil, water, satellite images and the field survey. The study also relied on several criteria in its assessment of the nature of the soil and its suitability for agricultural investment, such as nature of the surface, the suitability of the hydrological characteristics and some physical and chemical properties of soil. It is clear that there are large areas that can be invested due to the nature of their climate, flat surface and soil thickness as well as the physical and chemical characteristics of soil suitable for most agricultural activities as being sandy and sandy loam and clay loam soils, as well as the availability of both surface water resources of seasonal valleys and ground water represented in Dammam, UMEr Radhuma, Tayarat and Hartha of depth (50-350 m). There is also a complex hydraulic connection with these aquifers. The water quality is good; it is carbonate at the recharge area, but salinity increases towards discharge areas. It has been shown that salinity of the soil and water increases to east and north east of the region involved, precisely at Slibat depression, where it changes into a sulphatic or chloridic type. This water requires good investment and management for the purpose of economic benefit. The area lacks permanent human settlement except for it has only few houses scattered here and there of those who worked on cultivation during the season of growing. © 2018 DAV College.

Little stochastic parameter information about the soil in Nasiriyah, which is in southern Iraq, is available. Methods: In this paper, the Scale Of Fluctuation (SOF) for the site soil is examined, which is suggested for construction of the refinery fuel station project as no random parametric quantity has been studied in this region. A Cone Penetration Test (CPT) was performed as part of the site investigation to a depth of 20 m in the vertical direction, and 24 CPTs were analyzed within the site. The spatial correlation was computed using four methods, including Single Exponent (SNE), Square Exponent (SQE), Cosine Exponent (CSE) and Second-Order Markov (SOM). Identification of the soil type depended on the most recent classification chart, which is based on CPT results. The spatial correlation was evaluated for the vertical direction considering the cone tip resistance (q c ) component. Three trend functions were applied to all CPT soundings, including linear, quadratic and cubic polynomials, which were utilized to transform the non-stationary data to stationary data. Three modes of soil were employed, including the eight-meter soil layer, a twelve-meter soil layer and the entire twenty meters of soil, which includes both layers. Results and Discussion: The mean values of SOF were 0.54 m, 0.53 m, and 1.73 m for soil layers 8 m, 12 m, and 20 m, respectively. The high value of the last mean is attributed to the 20 m of stratification in the ground. This study also indicates that the SOF decreases as the polynomial degree increases, which is due to enhanced fitting. The coefficient of variation (COV) for the SOF shows little variability for most of the studied soil cases. © 2018 Ressol R. Shakir. | Bentham Science Publishers B.V. | 18741495 | |

Simulations were conducted at the turbine's best efficiency point with a Reynolds number of 2.01×10- 7 . Water injection was admitted from the runner cone in the stream-wise direction. The aim of this process was to investigate the influence of water injection on the turbine performance and the pressure pulsation. The water injection did not affect the nominal value of the turbine's power generation. Straight vortex rope was observed at the centerline of the draft tube. Moreover, helix-shaped vortex ropes were obtained near the draft tube surface. The water injection expands the central vortex rope, but it did not suppress or disrupt the helix-shaped peripheral vortex rope near the draft tube surface. The pressure fluctuation became less regular after the water injection, but the fluctuation level remained similar. Copyright © 2018 ASME. | American Society of Mechanical Engineers (ASME) | | |

Lagrangian coherent structures (LCS) are used to investigate the nonlinear vortex dynamics of flow past a single plate. The Finite-Time Lyapunov Exponent (FTLE) is calculated using the velocity data obtained from Large Eddy Simulations (LES). All simulations are conducted at Reynolds number of 50,000. LCS for a single plate is presented in this study to elucidate and comprehend highly turbulent flow interactions in these flows. The LCS is compared against most commonly used Eulerian structures which are contours of the vorticity and the Q-criterion. The FTLE fields reveal much clearer turbulent structures compared to the Eulerian structures. FTLE better describes the evolution of larger scale eddies. The Q-criterion of flows past an array of plates is also presented. Copyright © 2018 ASME. | American Society of Mechanical Engineers (ASME) | | |

Rossin College of Engineering and Applied Science, Lehigh University, Bethlehem, PA 18015, United States | Large eddy simulation (LES) is conducted to characterize oxygen dissolution in the draft tube of a pre-designed and optimized modular pump-turbine system. The air injection is applied over the peripheral surface on the draft tube. Mixture multiphase model is used to predict the spatial and temporal distribution of the air and the water. The simulation is conducted at the best efficiency point with a Reynolds number of 1.06×10 7 which is based on the rotation speed and the reference diameter of the runner. The vorticity is suppressed inside the draft tube, and the standard deviation of the power generation is decreased roughly 70% after aeration. The power generation is reduced by approximately 4-5% with peripheral aeration. Almost uniform dissolved oxygen concentration of 2-3 mg/l is observed in the radial direction near the outlet which is more than sufficient for wastewater treatment process.

The key mechanism behind the model is the active motion of the walls in line with the earlier model of Roberts. Our model is autonomous, nonlinear and is based on the partial differential equation describing the displacement of the wall in time and along the channel. A theoretical plane configuration is adopted for the walls at rest. For solving the equation we used the One-dimensional Integrated Radial Basis Function Network (1D-IRBFN) method. We demonstrated that different initial conditions always lead to the settling of pulse trains where an individual pulse has certain speed and amplitude controlled by the governing equation. A variety of pulse solutions is obtained using homogeneous and periodic boundary conditions. The dynamics of one, two, and three pulses per period are explored. The fluid mass flux due to the pulses is calculated. © EDP Sciences, 2018. | EDP Sciences | 9735348 | |

Box: 46219, Baghdad, Iraq; Yasser, H.A., Department of Physics, College of Science, Tni-Qar University, Tni-Qar, Iraq | In highly dispersive single-channel fiber, the optical signal propagation within channel leads to significant signal broadening and thereby, it interacts nonlinearly with a large number of neighboring signals. The overlap-states leads to create echo signals in "0" bit slots and amplitude jitter in "1" bits slots too that can significant limit the system performance due to increasing in a Bit Error Rate (BER). In this thesis, the Power Spectral Density (PSD) of the intrachannel nonlinearity distortion of a chirped Gaussian pulses is investigated theoretically using the small perturbation technique and the statistical quantum description of square M-QAM systems. Additionally, we provided an analytical expression using the perturbation coefficient matrix Xlmn (ω) of PSD to estimate a Signal to Noise Ratio (SNR). We assumed that the noise is Additive White Gaussian Noise (AWGN) and all transmitted signals undergo equal probability of distribution on coherent receiver where MATLAB programming are used to check out validity of analytical model. Our simulation shows that the intrachannel distortion is mitigated significantly by choosing of initial suitable parameters. Consequently, improving the SNR to acceptable values is achieved. © Medwell Journals, 2018. | Medwell Journals | 1816949X | |

Abnormal operations may be related to fault in one of system components; sudden internal thermal noise or even missing the input signal and can be extended to the maneuver target tracking case. Whenever the abnormal operation is detected, we can start tracking the states in this mode of operation. So the main problem may be reformulated to be detection of the starting point of the abnormal operation. The numerical simulation for fault estimation of phosphor furnace in different conditions are used to show the effectiveness of the proposed approach. © 2018 InforMath Publishing Group | InforMath Publishing Group | 15628353 | |

The power transformer was connected with earth air heat exchanger to decrease the temperature of (oil, core, and coils) of transformer which will increase its efficiency for preventing the damage and/or failure. The case study used the weather conditions of Nasiriya city (Iraq) at 1July with 50°C as maximum ambient temperature and full electrical load of the power transformer. In addition to different pipe diameter, length of earth air heat exchanger and different air velocity entering to pipe. The results showed the temperature of (oil, core, and coils) for power transformer decreased with increase the pipe length and earth air heat exchanger depth underground. The air velocities inlet to earth air heat exchanger that used in the study were (2, 4, 6 m/s respectively)and the results showed the increasing of air velocity inlet to earth air heat exchanger should decrease the temperature of (oil, core, and coils) for power transformer and increase the thermal conductivity of oil. The study concluded when using earth air heat exchanger in the power transformer and performance of power transformer will be increasing and led to decrease the temperature of oil about (18.5°C).The results showed a significant convergence with previous researches. © 2018 Serbian Society of Heat Transfer Engineers. | Serbian Society of Heat Transfer Engineers | 3549836 | |

Optical monitors are of special interest because they can be non-invasive. Among optical glucose sensors, fluorescent upconversion nanoparticles (UCNPs) have the advantage of good photostability, low toxicity, and exceptional autofluorescence suppression. However, to sense glucose, UCNPs normally need surface functionalization, and this can be easily affected by other factors in biological systems, and may also affect their ability for real-time sensing of both increasing and decreasing glucose levels. Here, we report YVO4: Yb3+, Er3+@Nd3+ core/shell UCNPs with Nd and Yb shell and GdVO4: Yb3+, Er3+@Nd3+ core/shell UCNPs with Nd and Yb shell that show sensitive, reversible, and selective optical glucose detection without the need for any surface functionalization or modifications. © 2018 Optical Society of America. | OSA - The Optical Society | 21593930 | |

Most of the proposed 3PAKE protocols use public keys to guarantee identities; however, the sharing of public keys may lead to various types of attacks, such as a man-in-the-middle attack, which allows an attacker to simply intercept and insert traffic traversing a network. In this paper, we briefly describe an updated three-party password-based authenticated key exchange protocol and analyse its security. The proposed TPAKE protocol does not share plain-text data. Data shared between the parties are either hashed or encrypted. Using the random oracle model, the security of the proposed TPAKE protocol is formally proven under the computational Diffie-Hillman assumption. Furthermore, the analyses included in this paper show that our protocol can ensure perfect forward secrecy and can also resist many types of common attacks.

In the Provinces of Basrah, Dhi Qar and Maysan the buffalo represents the main source for survival of local people in marshlands. The paper shows the situation in these areas, remarking the main critical points for buffalo breeding development. A survey in 24 buffalo farms was carried out by the Department of University of Firenze to verify the situation of buffalo farming in southern Iraq (years 2014 2016). In particular the study shows problems related to the shortage of food for animals, to the lack of suitable structures and infrastructures, to the poor herd management by farmers. In the paper the main critical points, which compromise the success of the breeding, are pointed out, with particular reference to animal welfare, animal health and labour (care of animals and risks for workers). Solutions to mitigate the scarce results are indicated. In particular some practical interventions carried out during a project funded by Italian Agency for Cooperation and Development are presented and discussed. Such interventions refer mainly to the application of feeding racks, systems for a safe capture of the animals, plants and equipment for heat protection. As conclusion, also in difficult and poor areas like Iraqi marshes, a correct design and a right application of simple constructive and plant solutions, with little employment of technological resources, coupled with a good training of farmers, can give a contribution to solve problems in buffalo breeding. © 2018, Eesti Pollumajandusulikool.

Bioprinting technologies based on photopolymerization principles are being used make such structures. In this paper, the effect of functionalization time on the mechanical morphology, swelling and degradation characterization of cross-linked alginate hydrogel is investigated. Alginate, chemically-modified with methacrylate groups and different reaction times is considered, by dissolving functionalized alginate with 1.5% photoinitiator solution and crosslinked by ultraviolet (UV) light (8 mW/cm2). Results show that by increasing the functionalization time, it was possible to obtain alginate material with a high level of unsaturation resulting in a less porous structure with high mechanical properties and a reduction of swelling. The influence of increasing the prepolymer concentration, reaction time and the amount of photoinitiator (PI) on mechanical and biomimetic properties of resulting hydrogels led to increased mechanical stiffness when measured at 10% strain. The swelling ratio of Photocrosslinked alginate hydrogels was studied and initial findings link this behavior to functionalization reaction time.

This paper describes a novel plasma-assisted bio-extrusion system (PABS) to produce functional-gradient scaffolds. It comprises two pressure-assisted and a screw-assisted printing head and plasma jets. Hybrid scaffolds consisting of a synthetic biopolymer and a natural hydrogel, and full-layer N2 plasma modified polymeric scaffolds were produced to assess the system. Water contact angle and in vitro biological tests confirm that the plasma modification alters the hydrophilicity properties of synthetic polymers and promotes proliferation of cells, leading to homogeneous cell colonization. It is also demonstrated the capability to produce multi-material structures. The results suggest that PABS is a promising system for the fabrication of functionally-graded scaffolds.

Obtaining a short-term disease risk prediction and thereby offering medical recommendations reliably and accurately are challenging in teleheath systems. In this work, a novel medical recommender system is proposed based upon time series data analysis for diabetes patients. It uses three decomposition methods, i.e., dual-tree complex wavelet transform (DTCWT), fast Fourier transformation (FFT) and dual-tree complex wavelet transform-coupled fast Fourier transform (DWCWT-FFT), with least square-support vector machine (LS-SVM) for short-term disease risk prediction for diabetes disease patients which then generates appropriate recommendations on their need to take a medical test or not on the coming day based on the analysis of their medical data. A real-life time series dataset is used for experimental evaluation. The experimental results show that the proposed system yields very good recommendation accuracy and can effectively reduce the workload for diabetes disease patients in conducting daily body tests. © 2018, Springer Nature Switzerland AG. | Springer Verlag | 3029743 | |

Synchronization characteristics and the influence of parameter mismatches on synchronization performances are investigated. Results: The results indicate that the complete synchronization can be realized under suitable system parameters. Through numerically studying synchronization quality and the influence of parameter mismatches on synchronization, the delay time of the transmitter, the delay time of the receiver, transmission time, coupling strength, and gain stages number have significant impact on the synchronization quality. Conclusion: Calculations indicate that correlation coefficient can be enhanced by high coupling strength, small stages number and similar delay times. The synchronization quality is sensitive to stages number value. In comparison with coupling strength, the mismatch in delay times has significant impact on the synchronization quality. © 2018 Bentham Science Publishers. | Bentham Science Publishers B.V. | 23520965 | |

The prevalence of congenital malformations differs widely between countries. Objectives: To determine the types of congenital anomalies among neonates and to identify the possible risk factors associated with congenital anomalies. Patients and Methods: A case-control study was carried out during 3years period (from the 1st of January 2015 to the 15th of December 2017). One hundred seventy-two neonates with congenital anomalies admitted to neonatal intensive care unit in Bint Al-Huda Teaching Hospital were involved in the study as a case group. A total of 305 neonates without congenital anomalies were randomly selected from neonates admitted to the same hospital for reasons other than congenital anomalies and including in the study as a control group. Results: Neural tube defects are the predominant type of congenital anomalies (31.9%), followed by congenital heart diseases (14.5%), cleft lip and palate (6.9%), and upper and lower limbs deformity (5.9%). Both genders equally distributed among patient and control group p-value > 0.05. The higher percentages of multiple congenital anomalies were detected among low birth weight neonates (30.6%), premature neonates (24.5%), neonates of mothers with advance age (> 35 years) (33.3%), grand multiparas (27.8%), and women with pregestational diabetes (37.5%).There is a significant positive association of low birth weight and premature neonates, young maternal age, chronic maternal illness, father occupation, and family history with the congenital anomalies, p-value < 0.05. Mother and Father Age, and prematurity were independent risk factors for congenital anomalies (OR 8.470, 17.367, 6.606, respectively). There is a highly significant association between congenital malformations with periconceptional folic acid intake, p-value < 0.001, (OR 5.746). Conclusion: The commonest congenital anomalies are neural tube defects, followed by congenital heart diseases, cleft lip and palate, and upper and lower limbs deformity. There is a positive association of low birth weight, chronic maternal illness, father occupation, and family history with the congenital anomalies. Parental age and prematurity were independent risk factors for congenital anomalies. Periconceptional folicacidin take protect against congenital malformations. © 2009-2018, JGPT. | Journal of Global Pharma Technology | 9758542 | |

Optimizing care coordination is a primary national concern for which yields significant cuts in medical care costs. However, the proposed metric-termed ‘care density’ for estimating care coordination is not completely accurate. Our objective is to compare the accuracy of the previously proposed ‘care density’, with our proposed ‘weighted care density’, ‘time varying care density’, and ‘time varying weighted care density’ in terms of predicting the cost of care. Our proposed metrics are based on the former care density, however, takes other variables into consideration, mainly patient hospitalization time frames and number of physician visitations. Our findings suggest that physicians coordinating over short time spans spike the cost of care above normal. © Springer International Publishing AG, part of Springer Nature 2018. | Springer Verlag | 3029743 | |

Graph clustering algorithm partitions a set of vertices in graphs into smaller sets (clusters) such that vertices in the same set are related to each other than to those in other sets. This study focuses the problem whether or not the fractal is helpful for graph clustering images. The most of the study used fractal dimension to calculate the self-similarity. In this study, we present a new algorithm, based on matching rang and domain fractal to find self-similarity properties of the data sets which can be used for graph clustering. It suggests that using fractal for image graph clustering can get the effective results. And this study presents an algorithm that automatically finds the number of clusters based on shared neighbors among vertices. The proposed algorithm is able to efficiently find graph clustering partitions for whole graphs. © 2018, Medwell Journals. | Medwell Journals | 1816949X | |

Such a dynamical system is a class C laser, whence the charactering features are intrinsically chaotic. Phase control relies on the addition of small parametric harmonic perturbations with adjustable phase. Phase control is demonstrated by changing both frequency and strength of the controlling perturbations. Our results show that phase control has two crucial effects on a quantum dot light-emitting diode. First, it can enhance the spiking behavior in either regular or chaotic regimes; second, it is able to turn periodic behavior to chaotic behavior with a minimal perturbation when a resonance condition at half of the driving frequency is achieved. © The Author(s) 2018. | SAGE Publications Ltd | 18479804 | |

However, numerous educational institutions and public and private universities in Iraq continue to use manual methods to exchange official and unofficial documents among departments. This situation highlights the need to implement novel technologies (both hardware and software) in educational institutions and understand the factors that hinder the adoption of electronic information sharing. This study investigated the critical variables that influence the adoption of modern communication technologies for information sharing among departments in technical institutions, particularly those in Nasiriya. Data were gathered through questionnaires distributed among lecturers in institute departments and staff in administrative offices. A sophisticated technique called SEM-PLS was utilized to analyze raw data through SmartPLS v.3 in addition to IBM SPSS. A significant relationship was observed between complexities and intention to use and between intention to use - > EIS adoption. No other relationship showed any significant influence on the adoption or intention to use electronic information sharing among departments in the Technical Institute in Nasiriyah. Results of this study will aid decision makers from technical institutes in understanding the barriers that impede electronic information sharing. Developers and designers of e-Services systems can also refer to the results to enhance systems based on end-user requirements. © Medwell Journals, 2018. | Medwell Journals | 1816949X | |

It was found that the fusion zone microstructure contains a complex microstructure of retained austenite, martensite, and bainite. The peak hardness in the heat affected zone of advance high-strength steel was greater than fusion zone hardness due to the higher hardenability of advance high-strength steel compared to fusion zone. Dissimilar DP600/EN 10130 spot welds show the highest trend to fail in pullout failure mode with good mechanical properties. Effects of weld microstructure and fusion zone size on mechanical properties dissimilar DP600/EN 10130 spot welds are analysed. © 2018, Springer International Publishing AG, part of Springer Nature. | Pleiades Publishing | 21954356 | |

This study has discovered several point mutations in the investigated genetic locus. In addition to the presence of a variety of SNPs in the intronic and 32 UTR regions, the present study was observed other variations that were varied in their nature from synonymous SNPs (or sSNPs) into non-synonymous SNPs (or nsSNPs) within the exonic portions of the NPM1 gene. On the other hand, all the observed SNPs were novel as it was confirmed by the dbSNP server that was showed the absence of any "known" SNPs in any observed locus. After the alignment of the coding portion of the sequenced samples with their parallel reference sequences, only one amino acid substitution was observed, which means the presence of only one non-synonymous SNP, in which, the amino acid Trp is substituted into Gly at 290 amino acid position as it was visualized by PyMoland the change in these proteins does not lead to the leukemia disease. In conclusion, the examined samples have several SNPs that despite their high degree of changeability they didn't show any clear association with the presence of any suggestive causal SNP with leukemia in benzene station workers. Nonetheless, the utilized bioinformatics tools were alsoprovided a predictive insight for the possible consequences of each observed SNP in both the structure and the biological function of the NPM1 gene product, needs an extensive study of more samples. © 2018 Biochem.

Fermi 6, Florence, 50125, Italy | This research reports a theoretical investigation on the role of filtered optical feedback (FOF) in the quantum dot light emitting diode (QD-LED). The underlying dynamics is affected by a sidle node, which returns to an elliptical shape when the wetting layer (WL) is neglected. Both filter width and time delay change the appearance of different dynamics (chaotic and mixed mode oscillations,MMOs). The results agrees with the experimental observations. Here, the fixed point analysis for QDs was done for the first time. For QD-LED with FOF, the system transits from the coherence collapse (CC) case in conventional optical feedback (COF) to a coherent case with a filtered mode in FOF. It was found that the WL washes out the modes which is an unexpected result. This may attributed to the longer capture time of WL compared with that between QD states. Thus, WL reduces the chaotic behavior. © 2018 Trans Tech Publications, Switzerland. | Trans Tech Publications Ltd | 2555476 | |

A cooled lid-driven top wall and a heated bottom wall are the only thermally uninsulated walls in this domain. A standard k-ε for the Unsteady Reynolds-Averaged Navier-Stokes (URANS) approach is applied to the turbulence calculation. Nusselt number, mean velocity profile, streamline, isothermal and isosurface temperatures are derived and presented in this paper to gain a better understanding of the effects of clockwise and anti-clockwise rotating cylinder directions on the heat transfer and flow patterns. Interesting changes in flow structure and heat transfer have been analysed for all rotational speeds and fluid types at both Reynolds number values. Nonlinear increases in Nusselt number have been observed by using nanofluid instead of pure water. The wall shear stress and turbulent kinetic energy profiles are found to be influenced by changing the Reynolds number and rotational speed and direction. Furthermore, incremental heat transfer rates at the walls can be achieved by increasing the cylinder rotation speeds, but these increases have weaker influences on the top wall than on the bottom wall. © 2017 Elsevier Ltd | Elsevier Ltd | 7351933 | |

First-principle of the density functional theory (DFT) method, which is implemented in the Gaussian 09W program are used to investigate the electronic properties, such as electronic band gap, DOS, total energy, dipole moment, HOMO, and LOMO energies of the GNFs with and without various concentrations of the BN impurities in various sites. There are very significant results. My founding results show that these properties of the GNFs depend on the concentrations of BN impurities and the geometrical pattern of the BN impurities in the GNFs. By increasing the distance between these impurities, the electronic band gap and the shape of the DOS are reduced and altered, respectively. So, the results offer that the electronic band gap value depends on the concentrations of BN impurities and sites of these impurities in the GNFs. The electronic dipole moments value is increased by increased the concentrations of the BN impurities. All structures became more stable due to the total energy is increased, excepted B, BN and B2N impurities, which is reduced and make GNFs structure unstable. Then, GNFs can be used in various applications because the electronic properties of the GNFs are controlled and modified with BN impurities. © 2017 Elsevier B.V. | Elsevier B.V. | 13869477 | |

Epileptic EEG signals are recorded as multichannel signals. A reliable technique for analysing multi-channel EEG signals is in urgent demand for the treatment and diagnosis of patients who have epilepsy and other brain disorders. Method In this paper, each single EEG channel is partitioned into four segments, with each segment is further divided into small clusters. A set of statistical features are extracted from each cluster. As a result, a vector of all the features from each EEG single channel is obtained. The resulting features vector is then mapped into an undirected weighted network. The modularity of the networks is found to be the best to detect epileptic seizures in EEG signals. Other local and global network features, including clustering coefficients, average degree and closeness centrality, are also extracted and studied. All the network attributes are ranked based on their potential to detect abnormalities in EEG signals. Results Eight pairs of combinations of EEG signals are classified by the proposed method using four well known classifiers: a least support vector machine, k-means, Naïve Bayes, and K-nearest. The proposed method achieved an average of 98%, 96.5%, 99%, rand 0.012, respectively, for its accuracy, sensitivity, specificity and the false positive rate. Comparisons were made using several existing epileptic seizures detection methods using the same datasets. The obtained results showed that the proposed method was efficient in detecting epileptic seizures in EEG signals. © 2017 Elsevier Ltd | Elsevier Ltd | 9574174 | |

From 320 diarrhoea cases enrolled between March and August 2016, 33 (10·3%, 95% confidence interval (CI) 8·4-12·4) cases were stool culture-positive for non-typhoidal Salmonella enterica. The most commonly identified serovar was Typhimurium (54%). Multivariable logistic regression analysis indicated that the odds of Salmonella infection in children from households supplied by pipe water was 4·7 (95% CI 1·6-13·9) times higher compared with those supplied with reverse osmosis treated water. Similarly, children from households with domestic animals were found to have a higher odds (OR 10·5; 95% CI 3·8-28·4) of being Salmonella stool culture-positive. The likelihood of Salmonella infection was higher (OR 3·9; 95% CI 1·0-6·4) among children belonging to caregiver with primary vs. tertiary education levels. Lower odds (OR 0·4; 95% CI 0·1-0·9) of Salmonella infection were associated with children exclusively breast fed as compared with those exclusively bottle fed. Salmonella infection was three times lower (95% CI 0·1-0·7) in children belonging to caregiver who reported always washing hands after cleaning children following defecation, vs. those belonging to caregivers who did not wash hands. The antimicrobial resistance profile by disc diffusion revealed that non-susceptibility to tetracycline (78·8%), azithromycin (66·7%) and ciprofloxacin (57·6%) were the most commonly seen, and 84·9% of Salmonella isolates were classified as multi-drug resistant. This is the first study on prevalence and antimicrobial resistance of Salmonella infection among children in this setting. This work provides specific epidemiological data which are crucial to understand and combat paediatric diarrhoea in Iraq. © 2017 Cambridge University Press. | Cambridge University Press | 9502688 | |

Never forget that the electronic health record (EHR) represents a unique and valuable human being: it is not just a collection of data that you are guarding, it is a life. Malicious codes are one of the significant reasons for the rising number of security violations of systems associated with the web or worked in an open domain. Some security organizations, that perceive the significance of security, develop security systems, for example, firewalls, virus scanning proxy servers, and intrusion detection system. In this venture, the integration of different techniques in network security is applied for healthcare system protection. This work portrays a wavelet neural network approach to the proposed Intelligent Healthcare Security System (IHSS) which include an intelligent firewall (IFW), intelligent network intrusion detection subsystem (INIDS), and intelligent web filter (IFW). Also, it used Multi-Layer Perceptron (MLP) for detection and classifying the attacks depend on an on-line analysis mechanism. Various wavelet neural network structures are analyzed to discover the optimal neural network with regards to the number of hidden layers. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

It describes the case of organization of distributed source routing when one of the border routers consistently solves two interconnected network tasks: calculation of the required routes and determination of the allocation order of link resource to be reserved in order to meet end-to-end QoS-requirements for the packet rate and the average packet delay. It has been found that the method provides iterative calculation of the desired control variables; the number of such iterations depended on the network structure, amount of available network resources, the number of flows and their requirements for QoS level. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The Pt nanorods electrodes were grown using a magnetron sputtering glancing angle deposition (GLAD) technique at different lengths (400 ad 600 nm long). The x-ray diffraction and SEM results reveal that that Pt nanorod are well-isolated, single crystal, and mainly oriented in Pt(100) which has the highest activity for ethanol adsorption and electrooxidation. The CV results show that the forward anodic current density (If) to the reverse anodic peak current density (Ib) ratio is calculated to be 4.8 and 7.2 for 400 and 600 nm Pt nanorods, respectively, while it is around 2.5 for a commercial high-surface-area-supported Pt (Pt/C) catalyst. Such high ratio for Pt nanorods electrocatalysts reflects the enhanced tolerance to the accumulation of carbonaceous species; a larger quantity of intermediate carbonaceous species is converted (oxidized) to CO2 in the forward scan compared to Pt/C, thus significantly enhancing the electrode electroactivity. © 2017 The Authors. | Electrochemical Science Group | 14523981 | |

In the present work, a type of shaped metal deposition using tungsten inert gas welding plus SS308LSi Wire technique was developed and integrated it with a new computer-aided metal deposition machine (CAMDM). The intent of this paper is to investigate the CAMDM system capabilities about the part modeling and slicing, deposition-path planning, and the part depositing processes. Additionally, this paper highlights the capabilities and limitations of the developed system. The results show that the current manufacturing system is capable to produce various features for metal components with accepted surface quality and free internal defects. The most suitable deposition-path strategy for depositing the solid and hollow components is the combined pattern method, which comprises of the spiral/contour path pattern for the outside/inside boundaries of the part and either spiral or zigzag/raster path pattern for the interior spaces. The controlling system of the present setup allows tuning the deposition parameters during deposition process which usually contributes with selecting of the proper path pattern to manufacture a free defects deposited parts. © 2017, King Fahd University of Petroleum & Minerals. | Springer Verlag | 2193567X | |

The system that takes into account in the study is left lead-donor-molecule-acceptor-right lead. The molecule, such as (phenyl, biphenyl, triphenyl, naphthalene, anthracene, and phenanthrene), is threaded by magnetic flux. This work contains two parts. First is computing density of states of the molecular structures as a closed system by density functional theory (DFT). Second is calculating the transmission probability and electric current of such molecular structures as an open system by steady-state theoretical model. Furthermore, the most important effects, taking into consideration are quantum interference, magnetic flux, and interface structure. Our results show that the connection of the molecule to the two leads, the number of rings, the magnetic flux, and the geometrical structure of the molecule play an important role in determining the energy gap of molecular structures. © 2017 Elsevier Ltd | Academic Press | 7496036 | |

It was found that the welding current has profound effect on the load–displacement characteristics. In the low welding current, welds failed in interfacial failure mode. Increasing welding current resulted in sufficient weld nugget growth to promote double-sided pullout failure mode with improved mechanical properties. Further increase in the welding current caused expulsion and failure mode was changed to single-sided pullout with reduced energy absorption capability. It was found that the fusion zone size is the key parameter controlling the mechanical properties of DP600 resistance spot welds in terms of peak load, maximum displacement and failure energy. © 2016 Institute of Materials, Minerals and Mining. | Taylor and Francis Ltd. | 3019233 | |

In this study, we have carried out first principles calculations of the structural and electronic properties of a germanium-doped fullerenes C20 bowl using density functional theory (DFT) at the B3LYP/3-21G level through the Gaussian 09W program packages. The doping effect has been investigated by varying the number of Ge dopants and by considering many doping positions for the same number. By Ge doping, N-type doping is induced in the fullerene C20 bowl. While the planar structure of the fullerene C20 bowl remains unaffected by Ge doping, and the electronic properties change from those of a semiconductor to a conductor with an increasing number of dopants. The electronic properties include the optimized structures, density of states (DOS) analysis, total energies, dipole moment, HOMO energies, Fermi level energies, LUMO energies, energy gaps, and work functions. It has been noted that isomers molded by choosing different doping positions differ significantly in the bond length, band gap and stability introduced. The band gap is found to be at a maximum when the Ge dopants are placed in the same ring points of the fullerene, due to the combined influence of symmetry breaking of the ring, and the band gaps are closed when Ge dopants are placed in opposite positions. These interesting results provide for the possibility of designing the band gap of a fullerene C20 bowl as required, and for its application in nanoelectronic and solar cell devices. © 2017 | Physical Society of the Republic of China | 5779073 | |

Conduction of the activation process was performed at varying impregnation ratios (0.5-2.0). Thermal decomposition was determined using thermogravimetric analysis (TGA). Porosity characterizations of AC were conducted by using N2 adsorption-desorption in order to characterise properties like pore volume, surface area, and micropore volume. To detect the presence of functional groups which were found on the surface of AC, Fourier Transform Infrared Spectroscopy (FTIR) analysis was utilised. Morphology of AC was determined using scanning electron microscopy (SEM) and X-ray spectroscopy (EDX). Experimental results showed that maximum AC surface area was 1737 m2/g.

Syndecan-1, a heparan sulfate proteoglycan, has been previously identified as a potential prognostic biomarker by multiple studies at the tissue and serum level. However, other studies have questioned its utility. Methods: Anti-Syndecan-1 immunohistochemistry was carried out on 157 prostate tissue samples (including cancerous, adjacent normal tissue, and non-diseased prostate) from three independent cohorts of patients. A population of Syndecan-1 positive stromal cells was identified and the number and morphological parameters of these cells quantified. The identity of the Syndecan-1-positive stromal cells was assessed by multiplex immunofluorescence using a range of common cell lineage markers. Finally, the burden of Syndecan-1 positive stromal cells was tested for association with clinical parameters. Results: We identified a previously unreported cell type which is marked by Syndecan-1 expression and is found in the stroma of prostate tumors and adjacent normal tissue but not in non-diseased prostate. We call these cells Prostate Cancer Syndecan-1 Positive (PCSP) cells. Immunofluorescence analysis revealed that the PCSP cell population did not co-stain with markers of common prostate epithelial, stromal, or immune cell populations. However, morphological analysis revealed that PCSP cells are often elongated and displayed prominent lamellipodia, suggesting they are an unidentified migratory cell population. Analysis of clinical parameters showed that PCSP cells were found with a frequency of 20-35% of all tumors evaluated, but were not present in non-diseased normal tissue. Interestingly, a subset of primary Gleason 5 prostate tumors had a high burden of PCSP cells. Conclusions: The current study identifies PCSP cells as a novel, potentially migratory cell type, which is marked by Syndecan-1 expression and is found in the stroma of prostate carcinomas, adjacent normal tissue, but not in non-diseased prostate. A subset of poor prognosis high Gleason grade 5 tumors had a particularly high PCSP cell burden, suggesting an association between this unidentified cell type and tumor aggressiveness. © 2017 Wiley Periodicals, Inc. | John Wiley and Sons Inc. | 2704137 | |

In this study, we investigate and discuss the tuning of the electronic properties of the fullerene C20 cage via various consternations and locations of silicon atoms. All calculations are based on the density functional theory (DFT) at the B3LYP/3-21G level through the Gaussian 09W program package. The optimized structures, density of state (DOS) analysis, total energies, dipole moments, HOMO energies, Fermi level energies, LUMO energies, energy gaps, and the work functions were performed and discussed. Our results show that the electronic properties of C20 cage do not only depend on the silicon impurity concentrations, but also depend on the geometrical pattern of silicon impurities in the C20 cage. The tuning of the electronic properties leads to significant changes in the charge transport and the absorption spectra for C20 cage via engineering the energy gap. So, we suggest that substitutional impurities are the best viable option for enhancement of desired electronic properties of C20 cage for using these structures in nanoelectronics and solar cell applications. © 2017, Pleiades Publishing, Ltd. | Maik Nauka Publishing / Springer SBM | 19907931 | |

The single benzene ring was threaded by a magnetic flux. The magnetic flux and applied gate voltages were considered as the key tuning parameter in the XNOR and NAND gates operation. All the calculations are achieved by using steady-state theoretical model, which is based on the time-dependent Hamiltonian model.

QD-WL transitions, which were not included in any other bistability work in QD structures, are also modeled here. Pumping optical field reduces the threshold of optical bistability (OB). The coupling field, which dressing DQD states and strengthens Kerr nonlinearity are increased. It is shown that optical multistability (OM) was the figure of merit for the stability behavior in DQD system, in the contrary with other researches, as a result from considering the calculation of all transition momenta, here.

In the course of the improvement, when the fault-tolerant routing problem was presented in optimization form, an optimality criterion has been formulated, which contains the conditions for path protection when it is possible to implement both single path and multipath routing strategies. The novelty of the proposed improvement lies in the feet that the path protection conditions are included in the optimality criterion in bilinear form. The efficiency and adequacy of the proposed improvement of the flow-based model of fault-tolerant routing has been confirmed in a number of computational examples in solving single path and multipath routing problems when implementing the path protection scheme in the network. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

One promising application of this structure is usage as a nanosensor for various gas molecules. The main purpose of the current study is to exploit the potential applicability of using GNFs as a nanosensor for small gas molecules (CO2, NO2, N2, O2, CO, and NO). For this reason, the interactions between these molecules in the horizontal and vertical directions with GNFs have been investigated by means of the density functional theory (DFT) method at the B3LYP/3–21 G level with the Gaussian 09 program. The band gaps, density of states (DOS), dipole moments, total energies, HOMO and LUMO energies, and Fermi level energies are calculated for GNFs with and without the above gas molecules. We found that GNFs are very sensitive to these gas molecules in the horizontal direction. The band gap was affected and reduced its value with these gas molecules. All the systems became unstable with gas molecules due to the total energies being reduced with gas molecules in the two types of directions,. An important result is that the interactions of these gas molecules in the horizontal direction results in fairly large alteration of the dipole moments of the GNFs and slight changes in the vertical directions in comparison with the pristine case of GNFs. The strong interactions between the O2 and the GNFs induce dramatic changes to the GNF's electronic properties and lead to a large reduction in the energy gap of the GNFs. However, the results of this work open a way for the development of new and effective nanosensors for gas molecules based on functionalized GNFs. © 2017 The Physical Society of the Republic of China (Taiwan) | Physical Society of the Republic of China | 5779073 | |

The work covers the samples preparation, testing, and analyzing. The samples were fabricated using the regular addition of the SiC particles as 0, 5, 10, 15, and 20 wt% of the total weight of epoxy resin. Samples of the short beam shear test were cut using CNC machine. The experiments were conducted according to the ASTM-D-2344 standard. The fracture surfaces of the laminate samples were observed by scanning electron and optical microscopy.

The α-κ-μ shadowed fading channel contains the generalized α-κ-μ fading and gamma distribution which represent the impact of multipath fading and shadowing, respectively. The performance of communication systems with dual-receiver switch and stay combining (SSC) in non-identical α-κ-μ shadowed fading channels is evaluated via analyzing different performance metrics. Specifically, the outage probability (OP), average bit error probability (ABEP), average channel capacity (ACC) and average detection probability of energy detection (ED) that is widely utilized in cognitive radio (CR) and ultra-wide band (UWD) systems are derived. The derived expressions are verified by the numerical results for various scenarios. A significant improvement in the performance of wireless communications systems as well as ED can be observed when the fading parameters increase. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Different parameters were considered such as the electric potential (e.g., 24, 40 and 60 V), hydraulic retention time (HRT) (e.g., 40, 60, 80, 100 and 120 min), sodium chloride (NaCl) concentration (e.g., 1, 3, 5 and 7%), pH (e.g., 3, 7 and 9), electrodes materials [e.g., aluminum (Al) and iron (Fe)] and distance between electrodes (e.g., 1, 2 and 3 cm). The best operational condition of electrolysis was then recommended. The electric potential of 60 V with HRT of 120 min at 5% of NaCl solution using Al as anode and Fe as cathode (kept at a distance of 3 cm) was the most efficient condition which increased the removal efficiencies of various parameters such as turbidity, salinity, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and heavy metals (e.g., Zn and Mn). The higher removal percentages of many parameters, especially COD (94%) and Mn (93%) indicated that the electrolysis is an efficient technique for multi-pollutants (e.g., organic, inorganic and heavy metals) removal from the landfill leachate. © 2017 Taylor & Francis Group, LLC. | Taylor and Francis Inc. | 10934529 | |

Methods: This study included 31 workers in 4 petrol station in different sites of Thi-Qar city/Iraq, who were working since more than 5 year in the petrol station and spend more than 12h work time, and ten healthy in different sites of a same city. Both groups age were ranged from 23 to 45 years old. Heavy material (Pb, Mo, and Cd) were determined by atomic absorption method using Shimadzu AA-7000 Dual Atomizer system. Hormones level (FSH, LH, and testosterone) were determined by enzyme linked fluorescent assay (ELFA) using the Bio Mérieux VIDAS Automated Immunoassay System. Results: Our results found significantly higher Cd, Mo, and Pb levels in Petrol workers compared to control (p < 0.05). While no significantly differences were detected between FSH levels in control and Petrol workers groups, significantly higher testosterone level was found in Petrol workers compared to control (p < 0.05). Conversely, significantly lower LH level in Petrol workers group than it in control group (p < 0.05). Conclusion: the petrol station workers exposure to Cd, Pb, and Mol which lead to increase its levels in their blood due to neglect the occupational safety instructions. Thus associated positively with the testosterone level and negatively with the LH level in their blood. © 2009-2017, JGPT. | Journal of Global Pharma Technology | 9758542 | |

Cold spray (CS) coatings of pure Al, blended Al/TiC and satellited Al/TiC were applied to Al substrates. A seven-fold increase in TiC area fraction was measured in the satellited coating compared to that in the blended coating. Coating thickness also increased as a result of increased ceramic deposition. Cross-sectional analysis revealed that the cohesion achieved between Al and TiC, during satelliting process, survives the CS process, and is hence an effective method of producing ceramic-metal coatings. © 2017 Elsevier B.V. | Elsevier B.V. | 0167577X | |

In the numerical study, finite volume method with standard k-ε turbulence model in three dimensional domains was selected. Three different types of water based (Al2O3, CuO, TiO2) nanofluids were employed in this simulation. The adopted boundary conditions were, expansion ratio (ER = 1.25, 1.67, and 2), Reynolds number ranging from 20, 000 to 50, 000, water based nanofluids used Al2O3, CuO, TiO2with volume fractions varied between 0 and 2% at different heat fluxes, varied from 4000 W/m2to 16, 000 W/m2. For experimental study, Al2O3water based nanofluid was used to validate the numerical results. The results show that the volume fraction of nanofluid and Reynolds number significantly affect the surface heat transfer coefficient; an increase in surface heat transfer coefficient was noted when both volume fraction of nanofluids and Reynolds number were increased for all the cases. The improvement of heat transfer was about 36.6% for pure water at the expansion ratio of 2 compared to heat transfer obtained in a straight pipe. Augmentation of heat transfer could be achieved by using nanofluid at expansion ratio 2 where the total improvements were about 45.2% (TiO2), 47.3%(CuO), and 49%(Al2O3). Also the increment in the pressure drop was about 42% for pure water at expansion ratio 2 compared with straight pipe whereas by using nanofluid they were 62.6% (TiO2), 65.4% (CuO) and 57.6% (Al2O3). Good agreements were observed between numerical and experimental results all the way. © 2017 Elsevier Masson SAS | Elsevier Masson SAS | 12900729 | |

Many scheduling algorithms have been proposed to schedule the tasks in cloud computing environment such as (SJF) and (FCFS) algorithms. This paper aims to improve the shortest job first scheduling algorithm in the cloud computing. In tasks scheduling (TS), the most important parameters are makespan and response time. Therefore, we have proposed a Modified Shortest Job First algorithm (MSJF) to minimize the completion time of the last task (Makespan) and minimize the average response time with maximizing the resources utilization. MSJF has two functions, one is calculating the average of tasks length and the other one is Load-Balancing between the virtual machines. One of the important advantages of MSJF is sending the longest tasks to the fastest Machine. We compared the result of our proposed algorithm MSJF with SJF and FCFS. The performance of MSJF is better compared to SJF and FCFS. © 2016 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

In this study the extraction of lipid from sardine fish waste was carried out using microwave-assisted extraction (MAE) and compared with Soxhlets and Hara and Radin methods. A mixture of two organic solvents isopropanol/hexane and distilled water were used for MAE and Hara and Radin methods. Meanwhile, Soxhlet method utilized only hexane as solvent. The results show that the higher yield of lipid 80.5 mg/g was achieved using distilled water in MAE method at 10 min extraction time. Soxhlet extraction method only produced 46.6 mg/g of lipid after 4 hours of extraction time. Lowest yield of lipid was found at 15.8 mg/g using Hara and Radin method. Based on aforementioned results, it can be concluded MAE method is superior compared to the Soxhlet and Hara and Radin methods which make it an attractive route to extract lipid from fish waste. © Published under licence by IOP Publishing Ltd. | Institute of Physics Publishing | 17578981 | |

We approach this problem using Evolutionary Game Theory (EGT), and characterize the robust equilibrium point(s) for this game. The game is formulated such that all the nodes take part in the decision process to avoid problems caused by unsuccessful revocation or over reacted revocation decisions. Each node in the network (interchangeably called benign node to distinguish it from the malicious node or the intruder) has three decisions to make: (a) abstain or do nothing; (b) self-sacrifice by disconnecting the intruder and itself; and (c) voting to isolate the intruding node. Each decision has its advantages and disadvantages and the Replicator Dynamics (RD) is used to show the dynamics of the nodes' decisions. By simulating the RD equation, two different cases emerge as Evolutionary Stable Strategies (ESS) where one of them is the desired ESS, and the other is not. Phase portrait diagrams are used to characterize the fraction of the M nodes needed to choose each one of these ESS's, the rate of convergence, and the effect of increasing the cooperation rewards. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The electronic properties of the GNS are investigated with and without various concentrations of phosphorus impurities in the various sites by using the first-principles of the density functional theory (DFT) method, which realized in Quantum Espresso packages. My founding results show that the electronic band structure of the GNS is not only depending on the concentrations of phosphorus impurities, but also depending on the geometrical pattern of phosphorus impurities in the GNS. Furthermore, I found out that there is an electronic band gap with a single phosphorus impurities and it is increased with increasing the concentrations of phosphorus impurities. Also, total energy is affected and decreased with increasing the concentrations of phosphorus impurities, which is led to make all structures are unstable and more reactive. Then, phosphorus impurities are significantly contributing to engineering, control and alter the electronic properties of the GNS, which is very important in various applications. © 2017 Elsevier Ltd | Elsevier Ltd | 381098 | |

A reductive amination method was developed for the tagging of sugars with the aim of it becoming part of a metabolomics work flow. The best separation of the common hexoses (glucose, fructose, mannose and galactose) was achieved when 2H5-aniline was used as the tagging reagent in combination with separation on a ZICHILIC column. The method was used to tag a range of sugars including pentoses and uronic acids. The method was simple to perform and was able to improve both the separation of sugars and their response to electrospray ionisation. The method was applied to the profiling of sugars in urine where a number of hexose and pentose isomers could be observed. It was also applied to the quantification of sugars in post-mortem brain samples from three control samples and three samples from individuals who had suffered from bipolar disorder. © 2017 Elsevier B.V. | Elsevier B.V. | 399140 | |

We have compared the thermoelectric properties of three zinc porphyrin (ZnP) dimers and a ZnP monomer and found that the "edge-over-edge" dimer formed from stacked ZnP rings possesses a high electrical conductance, negligible phonon thermal conductance and a high Seebeck coefficient of the order of 300 μV K-1. These combine to yield a predicted room-temperature figure of merit of ZT ≈ 4, which is the highest room-temperature ZT ever reported for a single organic molecule. This high value of ZT is a consequence of the low phonon thermal conductance arising from the stacked nature of the porphyrin rings, which hinders phonon transport through the edge-over-edge molecule and enhances the Seebeck coefficient.

In this regard, effective approach is associated with the implementation of hierarchical routing. This involves carrying out a structural and functional decomposition of the network, based on the introduction and supporting of multi-level routing decisions. However, the existing protocol implementation hierarchical routing does not contribute to maximization of the scalability of routing decisions because that only applied structural hierarchy and functional aspects are not involved.

Herein, we demonstrate a probe-style electrochemical sensor using highly flexible and conductive multi-walled carbon nanotubes (MWNT) yarns. TheMWNTyarn-based sensors can be fabricated onto micro Pt-wire with a controlled diameter varying from 100 to 300 µm, and then further modified with Nafion via a dip-coating approach. The fabricated micro-sized sensors were characterized by electron microscopy, Raman, FTIR, electrical, and electrochemical measurements. For the first time, the MWNT/Nafion yarn-based probe sensors have been assembled and assessed for high-performance dopamine sensing, showing a significant improvement in both sensitivity and selectivity in dopamine detection in presence of ascorbic acid and uric acid. It offers the potential to be further developed as implantable probe sensors. © 2017 by the authors. Licensee MDPI, Basel, Switzerland. | MDPI AG | 14248220 | |

Corticosteroids can have limited therapeutic effects in COPD patients. NTHi causes corticosteroid insensitive cytokine production from COPD alveolar macrophages. We investigated the mechanisms by which NTHi causes corticosteroid insensitive inflammatory responses, and the effects of NTHi exposure on COPD macrophage polarisation. Method: Alveolar macrophages from COPD patients and controls were exposed to NTHi in conjunction with the corticosteroid dexamethasone and/or the p38 MAPK inhibitor BIRB-796. Cytokine release, GR phosphorylation and modulation and macrophage phenotype were analysed. Results: Dexamethasone significantly inhibited NTHi induced TNF-α, IL-6 and IL-10 from COPD macrophages but, CXCL8 was not suppressed. BIRB-796 combined with dexamethasone caused significantly greater inhibition of all cytokines than either drug alone (p<0.05 all comparisons). NTHi caused phosphorylation of GR S226 reducing GR nuclear localisation, an effect regulated by p38 MAPK. NTHi altered macrophage polarisation by increasing IL-10 and decreasing CD36, CD206, CD163 and HLA-DR. Conclusion: NTHi exposure causes p38 MAPK dependent GR phosphorylation associated with decreased GR function in COPD alveolar macrophages. Combining a p38 MAPK inhibitor with corticosteroids can enhance anti-inflammatory effects during NTHi exposure of COPD alveolar macrophages. NTHi causes macrophage polarisation that favours bacterial persistence. © 2017 The Author(s). | BioMed Central Ltd. | 14659921 | |

This method is implemented by depositing continuous cold or hot-water melted via welding arc plasma heat. This paper presents the designing, constructing, and controlling of an additive manufacturing system using TIG plus wire based Shaped metal deposition (TW-SMD) method. The aim of the current study is to design and develop an integrated system which is able to reduce time consuming and boring task of deposition process. The developed additive system is capable of producing near net shaped components of sizes not exceed 400 mm in 3 directions directly from CAD drawing. The results showed that the developed system succeeded to produce near net geometries and error-free depositions for various features of SS308LSi components.

The temperature range studied covers the hot climate regions. 250 KVA distribution transformer is chosen as a study model. A novel cooling fluid is proposed to improve the cooling performance of this transformer, transformer oil-based microencapsulated phase change materials suspension is used with volume concentration (5–25)% as a cooling fluid instead of pure transformer oil. Paraffin wax is used as a phase change material to make the suspension, in addition to the ability of heat absorption due to melting, the paraffin wax considered as a good electrical insulator. Results obtained show that, using of MEPCM suspension instead of pure transformer oil lead to improve the cooling performance of transformer by reducing its temperature and as a consequence increasing its protection against the breakdown. The melting fraction increased with increasing outside temperature up to certain temperature after which the melting fraction reach maximum constant value (MF = 1) which indicate that, the choosing of PCM depend on the environment in which the transformer is used. © 2016 Karabuk University | Elsevier B.V. | 22150986 | |

Our results show that the electronic properties of GNFs do not only depend on the oxygen impurity concentrations, but also depend on the geometrical pattern of oxygen impurities in the GNFs. Additionally, we also found interesting electronic properties of GNFs structure, which significantly contribute to that oxygen dopants cause a decreased energy gap.

Plant parts and corresponding water and sediment samples were taken at the inflow and outflow points of the four ponds at the beginning and at the end of the growing season. Concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni and Zn in the different compartments were estimated and their removal efficiency assessed, reaching more than 90% for Fe, Mn and Ni in spring and fall as well in the water compartment. The above- and below-ground cattail biomass varied from 0.21 to 0.85, and 0.34 to 1.24 kg dry weight/m2, respectively, the highest values being recorded in the fourth pond in spring 2011. The root system was the first site of accumulation before the rhizome, stem and leaves. The highest metal concentration was observed in roots from cattails growing at the inflow of the system's first pond. The trend in the average trace element concentrations in the cattail plant organs can generally be expressed as: Fe > Mn > As > Zn > Cr > Cu > Ni > Cd for both spring and fall. While T. latifolia removes trace elements efficiently from landfill leachates, attention should also be paid to the negative effects of these elements on plant growth. © 2016 | Chinese Academy of Sciences | 10010742 | |

The present rate equations model consists of three equations for the electron density in the conduction band and one equation for photon density in cavity length. Two equations were derived to calculate the noise and modulation response. Calculations in this paper are focused on the effect of optical phonon emission rate τij, number of stages and the gain coefficient on the noise spectrum and modulation response in these types of semiconductor lasers. The results indicate the strong effect of optical phonon emission rate, gain coefficient and number of stages on the dynamics properties of QCLs. The static properties such as the population inversion, threshold injection current and steady state photon density deviate from the ideal values with increasing in τ21 .The effect of optical phonon emission rate τ21 has similar effect to that of the photon lifetime on the noise spectrum in comparison with other times. | Iranian Chemical Society | 23225521 | |

The number of monoclonal antibodies (mAbs) that have already been approved for therapeutic applications and for use in clinical trials have significantly increased in the past few years. In view of the side effects and limitations of mAbs, several improvements and modifications to monoclonal antibodies have been developed. These modifications have facilitated the use of mAbs in various forms of therapeutic applications such as treatment of infectious diseases caused by bacterial, viral, fungal and parasitic organisms. Monoclonal antibodies have also been applied in the treatment of non-infectious diseases such as cancer, immune diseases, arthritis and other disorders resulting from organ transplantation. This review highlights mAbs applications in biomedicine, and discusses state-of-the-art technologies related to their potential uses. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.

The cubic cavity with moving isothermal sidewalls has uniform heat flux on the middle part of the bottom wall, and the other remaining walls forming the enclosure are adiabatic and stationary. The relevant parameters in the present research include Reynolds number Re (5000–30,000), nanoparticle diameter (25 nm–85 nm), and nanoparticle volume fraction (0.00–0.08). In general, remarkable effects on the heat transfer and fluid patterns are observed by using nanofluids in comparison to the conventional fluid. Different types of nanofluids or different diameters of nanoparticles can make pronounced changes in the heat convection ratio. In addition, increasing in either volume fraction of nanoparticles or Reynolds number leads to increasing in the Nusselt number, fluctuation kinetic energy and root mean square velocity of the fluid in the domain. It is also found that both URANS and LES methods have shown good performance in dealing with unsteady flow conducted in this project. However, the comparisons have elucidated clearly the advantages of the LES approach in predicting more detailed heat and flow structures. © 2017 Elsevier Ltd | Elsevier Ltd | 7351933 | |

This paper reports for the first time using the pulsed current shaped metal deposition technique for fabricating components using cold wire of AISI 308LSi stainless steel. The aim of this work was to investigate and compare the effect of pulse frequency and other deposition process parameters on the morphology aspects and microstructure characteristics of the manufactured components using pulsed and continuous current processes. The obtained results reveal that the structure of the deposited specimens produced via pulsed arc current is generally having finer grains, high residual ferrite, and absence of columnar grains. Pulse frequency and current ratio have a significant influence on the surface morphology and microstructure of the manufactured parts. Good metallurgical bonding with no sensitization effects can be seen in all tested specimens. The presented additive layered manufacturing method can be recommended for near net-shaped processing of austenitic stainless steel components, and it can be used as an alternative manufacturing method for fabricating metal components with free defects, higher corrosion resistance, and superior mechanical properties. © 2016, Springer-Verlag London. | Springer London | 2683768 | |

Local Directional Number Pattern (LDNP) technique is proposed to extract the features of the face and categorized with one of the algorithms for classification. LDNP encrypts directional information of the facial texture in a compact way to eight different directions through calculating the edge responses in the neighborhood, by choice most positive and negative directions of those edge responses to produce a descriptor. Positive and negative directions provide sufficient information on the structure of the neighborhood. It allows distinguishing the intensity changes for example from light to dark and dark to light. The LDNP is a method more compact than previous methods in which they can extract many facial features that integrate with each other into a feature vector, which is then, used it as a face descriptor. This approach is extended in this work to improve recognition accuracy. In the existing method, Support Vector Machine (SVM) with LDNP approach which used for facial expression. The performance of SVM is destitute. In the proposed model Feed Forward Neural Network (FFNN), is used to improve the accuracy performance. | Institute of Electrical and Electronics Engineers Inc. | | |

In this paper Epileptic seizure detection is done using electroencephalogram signals (EEG). Discrete wavelet transform (DWT) method is a common method to extract four features from the (EEG) signal, and then classify them. To improve and increase the efficiency of extraction of features and to get the best results of classification, we used new method for the extraction of features, namely Higher Order Statistics of Wavelet Packet Decomposition (HOS of WPD). Using this method we get 90 features from every signal, it is then classified using the four classifiers, as follows Artificial Neural Network (ANN), Support Vector Machine (SVM), K-nearest neighbour (KNN), and Naive Bayes.

Organic species present during growth make carbon as common contaminant, so various structural configurations of carbon in tetragonal PbTiO3 have been investigated. We have analyzed the electronic properties and vibrational modes using density functional calculations, from which we find that carbon contamination may be electrically active, such as substitution of Pb or O, or electrically passive, such as for iso-electronic substitution of Ti. The most stable site under most conditions is substitution of Ti, but due to the structural arrangement and chemical bonding it is a fixed electric dipole, with an activation energy for reorientation around 1.5 eV.

Glass fiber reinforced polymers (GFRPs) are known as cost-effective materials offering long-term durability and less maintenance. As a result, these materials show great potential for use in the civil engineering applications. Due to the high cost of the manufacturing die, pultruded GFRP tubes are produced in specific cross-section dimensions only. For high load applications and to comply with the serviceability requirements, a number of these pultruded sections can be assembled together by gluing them appropriately. This study presents an experimental investigation onto the flexural behavior of glued GFRP tube beams with 1, 2, 3 and 4 - cells filled with concrete under four-point loading. The results show that the strength of the 4 cells glued beams increased by 150 % and 88% for hollow and filled beams, respectively, compared with its counterpart single cell beam. The filled beams failed at 42 – 88 % higher load and showed 10 – 22 % higher stiffness compared with their hollow counterparts. The results also show that gluing small section tubes to produce large section beam is a practical solution to enhance the flexural performance of the composite tubes. © 2017 APFIS.

The current study aimed to determine the diversity of bacterial infection in urinary bladder tumours and studying the immunoexpression of CD14 in bladder tissues associated with bacterial infection. Materials and Methods: In total, 65 patients with bladder tumours with urine and paraffin embedded tissue samples were enrolled in the study, among these patients, 50 had bladder carcinoma (BC) and 15 had benign tumours (BT). Specific culture media and biochemical tests were used to isolate and identify bacterial species and immunohistochemistry (IHC) was used to detect CD14 tissue expression in both groups. Chi-square test was used to compare the difference between percentages of this study by using SAS. Results: The results showed that 37 out of 50 BC patients were positive for gram-negative bacteria, 3 out of 50 patients were positive for gram-positive bacteria and 10 out of 50 patients were negative growth. All BT patients showed presence of gram-negative bacteria. IHC staining showed that CD14+ was significantly over expressed in BC patients compared with BT patients (82% vs. 46.7%, p≤0.01). CD14 expression was also high in gram-negative bacteria infected bladder tissues in patients with both BC and BT and its expression was significantly correlated with this type of bacterial infection (p<0.01). Conclusion: A significant association between CD14 expression and bacterial infected tissues was found and concluded that CD14 activation driven by microbial inflammation probably contributes to bladder cancer. © 2017 Hind Mizhir Mousa et al. | Asian Network for Scientific Information | 17273048 | |

Using constant current for CP is the most popular approach in practice, particularly for the structures exposed to atmospheric conditions. However, for submerged structures, the situation of the reinforcement is quite different, if the constant current approach is efficient to provide adequate protection is still not very clear. To have a deep understanding for the question, an experimental investigation has been conducted for reinforced concrete specimens protected by impressed electrical current of both constant current density and constant potentiostatically controlled potential, respectively. Reinforced concrete specimens had varied chloride contents and submerged into salty solutions that have the same amount of chloride added in the concrete mixture have been examined. The performance of protection has been evaluated and discussed. Corrosion potentials and concrete resistivity were also measured and compared with those of chloride content/corrosion rate. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Reinforced and non-reinforced concrete specimens of varied chloride contents and exposed to ventilated condition at 50±5% relative humidity and room temperature of 20±3°C were investigated. Five levels of cathodic current densities of 5, 10, 15, 20 and 25 mA/m2 were applied during the cathodic polarization. A new correlation between the concrete resistivity and reinforcement corrosion rate was obtained and compared with previous work. The effect of concrete resistivity and polarization resistance on the reinforcement potential shift were also discussed. In the last, based on the findings of the research, some useful conclusions can be drawn. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Considerably the sand cushion is one of the best techniques used frequently to treat the weak soil and enhance its mechanical properties such as bearing capacity and consequently reduce its settlement. In this research an experimental study has been carried out to study the load-settlement behaviour of two groups of footings.The first group consists of footing on natural soil (weak soil) and footing on the flat sand cushion, the second group consists of footing on a curvilinear sand cushion and the footing on the reinforced curvilinear sand cushion. Test results showed that, the use of a sand cushion, reduce the soil settlement and increase the load applied capacity. The measurements of settlement are taking place for the first and second groups at the average load of P = 75 kPa. It has been indicated that, the use of flat cushion is allowed to reduce the soil settlement up to 13%, the curvilinear sand cushion reduced the settlement up to 16% while the curvilinear sand cushion that has been reinforced with geotextile reduced the settlement by 34% compared with the natural soil base settlement under the same load. © Medwell Journals, 2017. | Medwell Journals | 1816949X | |

The experimental results showed that ε', ε" and tand increased with increasing temperature and is due to greater freedom of movement of the dipole molecular chains within polymer at high temperature. The value of ε' decreased with increasing frequency which indicates that the major contribution to the polarization comes from orientation polarization. Ac conductivity F ac and impedance (Z) of doping polymer behaviors as function of frequency and temperature have also been investigated. © Medwell Journals, 2017. | Medwell Journals | 1816949X | |

In this paper, the electroosmotic flow in square microchannels has been numerically investigated by developing a model from the basic governing equations (continuity, momentum, energy, Laplace and Poisson-Boltzmann equations). These equations were numerically solved by CFD program for two fluids (water and PBS). The study considered the external applied electric field and zeta potential to interrogate their potential effects on electroosmotic flow. Thermal characteristics of electroosmotic flow have been also studied by calculating the temperature distribution through electroosmosis micropump region. The results confirm the considerable effect of applied electric field, concentration of electrolyte fluid and zeta potential on microflow velocity and flow rate. The PBS gave higher velocity and flow rate values compared with water, and there was only a slight increase in temperature due to Joule heating effect. © 2017 Praise Worthy Prize S.r.l. - All rights reserved. | Praise Worthy Prize | 19708734 | |

Therefore, this study introduces pultruded multi-celled GFRP beams filled with low strength concrete. The flexural behaviour of beams made up of 1, 2 and 3 pultruded GFRP square sections (125 mm × 125 mm × 6.5 mm) and filled with concrete having low compressive strength was investigated. The composite beams were subjected to four-point static bending test to determine the strength, stiffness and failure mechanisms. The results of the experimental investigations showed that the failure stress of 2 and 3 cells beams is 98% and 85% compared with single cell beam, respectively. However, the filling percentages are 50% and 33%, respectively. All the tested beams were failed due to compression failure of the GFRP profile. Furthermore, the effective stiffness of 2 and 3 cells is 95% and 96%, respectively compared with single cell section. © 2017 Taylor & Francis Group, London. | CRC Press/Balkem | | |

Allowance of the energy gap of the polymer conjugated is an object of great interesting debit for the possible removal of a doping in the preparation of highly conductivity polymers. Thiadiazoles derivatives are structural foundation of the polymer materials. In this present work, the electronic properties of graphene nanoflakes (GNFs)-phenanthrene-1,3,4-thiadiazoles oligomers are studied and discussed. Where thiadiazoles is expanded from one to 9 unit's molecules at the structure. The energy gap, HOMO, LUMO distribution, total energy, Fermi level energy, work function, maximum wavelength absorption, vertical absorption energies, and oscillator strengths are calculated for each molecule. All calculations are carry out by usage density function theory (DFT) and depended time density function theory (TD-DFT) with the B3LYP/6-31G model in the Gaussian 09W software packages. Results show that increasing the number of monomeric units lead to great enhance in the electronic properties, which caused it decreased the band gap from 3.17 eV in the system with one unit of thiadiazole just to 1.35 eV in the system with 9 units of thiadiazole. This case is raised the value of maximum absorption wavelengths to >500 nm to give the better performance in optoelectronic and solar cell, as these structures have prime absorption bands within the solar spectrum. © 2017 | Elsevier B.V. | 22113797 | |

At present, governments are implementing programs to demonstrate the advantages of utilizing information and communication technologies in government administration. Using technology could result in internal efficiency and effectiveness of government actions. Evaluating the performance of the information system can reveal weak and strong points, which could be used in improving the system. For many years, scholars have pushed for assessing user satisfaction as a construct for evaluating such systems. Measuring the performance of the e-Government, which is the core of strategies employed by most Arab countries, could lead to the realization and application of the expected benefits of the system. Nonetheless, despite the popular use of e-Government services and applications worldwide, the assessment of electronic services in Iraq has been neglected in practical and theoretical aspects. Moreover, the new portal in Iraq, which is called "citizen e-Government," has decreased the number of citizens conducting business via electronic transactions. The portal design is complex and not user friendly. To respond to this need, this study assesses "Citizen E-Government Portal," which is a new portal in the Communications Directorate in Thi-Qar, according to employee perspective. The study used five constructs, namely, attractiveness, controllability, helpfulness, efficiency, and learnability, in the evaluation. Our findings revealed several weak points in the proposed e-portal, such as slow speed and unavailability of information needed by users. Hence, introductory explanations are needed to improve the proposed portal to increase user rate. | Politechnica University of Bucharest | 22863540 | |

The monthly average discharges of Euphrates River for the period (1995-2015) were used in this research. Three layers feed-forward network with sigmoid hidden neurons and linear output neurons are used in this research, the ANN is trained with Levenberg-Marquradt back-propagation algorithm. The total number of observations data was equal to 248 samples; divided into three statistical groups (148 samples as a training group, 50 samples as a validation group, and 50 samples as a testing group). Two preceding discharge values (Qt-1, Qt-2) were used for predicting the discharge value (Qt). The clustering radius is an important parameter to determine the number of clusters and fuzzy if-then rules in ANFIS model. The best value of clustering radius (0.8) was associated with lowest value of checking root mean squared error (33.716).According to statistical evaluation criteria, ANFIS model was better than ARIMA model, and slightly better than ANN model. The superiority of the ANFIS technique to the ANN and ARIMA models due to the fuzzy clustering of the input space and for creating a rule-base to generate the output. ANFIS model can be used by the Iraqi Ministry of Water Resources to extract results close to reality and give an approximate estimate of the expected flow values in the Euphrates River, better than using other high-cost models such as conceptual models or physically based models. © Research India Publications. | Research India Publications | 9734562 | |

Solar ponds are a simple, low-priced and efficient way to collect and store incident solar radiation; they have enormous capacity and huge unrealised potential. The most effective and widely-used type is the salinity gradient solar pond (SGSP), which can provide long-term storage, large capacity, and sufficient year-round power for a wide range of domestic, industrial and commercial purposes. It is essential to understand the best forms of construction and maintenance, including how to overcome the most significant challenge, that of establishing the different layers of water with their varying levels of saline concentration, as well as how to maintain these levels for optimal performance. This study investigates how to predict variations in salt concentrations over the pond's lifetime, in order to maintain maximum performance. The paper derives analytical formulae to calculate how concentrations in the upper and lower convective zones (UCZ and LCZ) change over time. It also explores the different responses of ponds with vertical walls and inclined walls. The computed concentrations were compared with actual measurements from a small experimental pond, which had a surface area of 1 m2 and a total depth of 1 m, comprising UCZ, non-convective zone (NCZ) and LCZ with depths of 0.1, 0.5, and 0.4 m respectively. The results were also compared with the results of previous experiments from established ponds. An acceptable agreement was achieved. The results illustrated that the derived formulae can be used to estimate salt concentrations in the UCZ and LCZ. The outcomes also show that the inclination of the walls affects concentration levels in the UCZ, while its impact on the LCZ concentration is slight. The findings of this study could form the basis of future research, which could investigate other factors affecting salt concentration in the layers of a SGSP, such as wind speed, temperature and the timing of salt injections to the LCZ. © 2017 Elsevier Ltd | Elsevier Ltd | 0038092X | |

The Long-Term Evolution (LTE) is a 4G mobile communications standard set by International Communication Union (ITU), specifically ITU Radio communication Sector (ITU-R). At the moment, video traffic and telecommunications grow under the expansion of LTE, which is considered as the actual motivating access technology of 4G network. Throughout the deployment of LTE, various transport protocols are advised and broadly experimented, for instance, TCP, SCTP, DCCP and UDP that may execute differently on 4G networks subject to the network scenarios and parameter settings. Even though the deployment of LTE is swiftly enhanced, there is a lack of performance evaluation of its protocols. Hence, a widespread scrutiny is required for the evaluation of the operation of numerous protocols for high-end applications such as multimedia. Adopting these applications with flexible quality of service constraints with improved usage of resources is a challenging task. In this paper, the output results of different transport protocols for multimedia streaming applications, e.g., video, through extensive simulations are analyzed. The performance of an MPEG-4 video streaming is evaluated using NS-3. The performance metrics used are delay, jitter, throughput, and packet loss. These metrics are evaluated at the base station via TCP, SCTP, DCCP and UDP protocols over the 4G-LTE technology. The obtained results show that the DCCP performs the best in throughput improvement with the minimization of delay and jitter as compared to UDP, TCP, and SCTP. | Elsevier B.V. | 18770509 | |

In this paper, an effective medical recommendation system that uses a fast Fourier transformation-coupled machine learning ensemble model is proposed for short-term disease risk prediction to provide chronic heart disease patients with appropriate recommendations about the need to take a medical test or not on the coming day based on analysing their medical data. The input sequence of sliding windows based on the patient's time series data are decomposed by using the fast Fourier transformation in order to extract the frequency information. A bagging-based ensemble model is utilized to predict the patient's condition one day in advance for producing the final recommendation. A combination of three classifiers-artificial neural network, least squares-support vector machine, and naive bayes-are used to construct an ensemble framework. A real-life time series telehealth data collected from chronic heart disease patients are utilized for experimental evaluation. The experimental results show that the proposed system yields a very good recommendation accuracy and offers an effective way to reduce the risk of incorrect recommendations as well as reduce the workload for heart disease patients in conducting body tests every day. The results conclusively ascertain that the proposed system is a promising tool for analyzing time series medical data and providing accurate and reliable recommendations to patients suffering from chronic heart diseases. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Distributed denial of service (DDoS) attacks are the second most prevalent cybercrime attacks after information theft. DDoS TCP flood attacks can exhaust the cloud's resources, consume most of its bandwidth, and damage an entire cloud project within a short period of time. The timely detection and prevention of such attacks in cloud projects are therefore vital, especially for eHealth clouds. In this paper, we present a new classifier system for detecting and preventing DDoS TCP flood attacks (CSDDoS) in public clouds. The proposed CSDDoS system offers a solution to securing stored records by classifying the incoming packets and making a decision based on the classification results. During the detection phase, the CSDDOS identifies and determines whether a packet is normal or originates from an attacker. During the prevention phase, packets, which are classified as malicious, will be denied to access the cloud service and the source IP will be blacklisted. The performance of the CSDDoS system is compared using the different classifiers of the least squares support vector machine (LS-SVM), naïve Bayes, K-nearest, and multilayer perceptron. The results show that CSDDoS yields the best performance when the LS-SVM classifier is adopted. It can detect DDoS TCP flood attacks with about 97% accuracy and with a Kappa coefficient of 0.89 when under attack from a single source, and 94% accuracy with a Kappa coefficient of 0.9 when under attack from multiple attackers. Finally, the results are discussed in terms of accuracy and time complexity, and validated using a K-fold cross-validation model. © 2013 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

If these ponds are to be implemented successfully, then a more complete understanding of the mechanisms and phenomena governing their behaviour is required. Evaporation has been shown previously to be the dominant mode of heat loss from the pond surface, and the fresh water that would need to be added to maintain the pond's inventory could potentially add significantly to operating costs. To this end, an experimental unit was constructed to examine and observe the behaviour of a salinity gradient solar pond (SGSP) before and after covering the pond with a thin layer (0.5 cm) of paraffin, with the aim of eliminating evaporation. The unit was run for 71 days in Nasiriyah, Iraq. This is the first study to attempt to completely eliminate the harmful effects of evaporation on solar pond performance using a liquid layer. The layer successfully eliminated the significant evaporation observed from the uncovered pond and crucially, while the salinity gradient through the non-convective zone remained substantially intact over the course of the study, the temperature profile became approximately uniform throughout the entire pond after about 50 days. This behaviour has significant implications for the construction of the pond, as it may mean that if evaporation can be largely suppressed, the salinity gradient may not be necessary for the pond to capture and efficiently store heat. Furthermore, the effects on evaporation of different climatic factors such as relative humidity, wind speed, ambient temperature and solar radiation were considered by analysing data measured on-site and longer-term meteorological data. The results showed that ambient temperature, solar radiation and humidity have a significant correlation with the evaporation rate; and their impact varies seasonally. A more comprehensive multiple regression analysis showed that ambient temperature has the highest impact on evaporation, while the effect of the incident solar radiation is insignificant. Such insights are vital in the design and siting of solar ponds, and can be used to minimise evaporative losses. © 2017 | Elsevier Ltd | 0038092X | |

Evolutionary game theory is used to capture the long-term continuous behavior of the APTs on the cloud storage devices. Two APT defense games with discrete strategies are formulated, in which both an APT attacker and a defender compete to control one or multiple storage devices regarding their attack or defense intervals. The dynamical stability of each defense and attack strategy pair is studied according to the replicator dynamics criteria to characterize the locally asymptotically stable equilibrium strategies. The evolutionary stable strategy is discussed in each game, which is a subset of the asymptotically stable Nash equilibrium (NE). The phase portraits provide the locally asymptotically stable points of the APT defense game, which represent the NE showing the relationship between the asymptotic stability and evolutionary stability. © 2017 IEEE. | Institute of Electrical and Electronics Engineers Inc. | 21693536 | |

Changing metal atom has little effect on the thermal conductance due to the phonons. The room-temperature Seebeck coefficients of these junctions are rather high, ranging from 90 μV K-1 for Cu, Ni and Zn-porphyrins to -16 μV K-1 for Co-porphyrin. These values could be further increased by lowering molecular energy levels relative to the DFT-predicted Fermi energy. In contrast, the phonon contribution to the thermal conductance of these junctions is rather insensitive to the choice of metal atom. The thermopower, thermal conductance and electrical conductance combined to yield the room-temperature values for the thermoelectric figure of merit ZT ranging from 1.6 for Cu porphyrin to ∼0.02 for Ni-porphyrin. © 2017 the Owner Societies. | Royal Society of Chemistry | 14639076 | |

Although major advances have been recorded in the diagnosis of infectious diseases in humans, parasitic diseases continue to present challenges, particularly in resource-poor countries, and this is mainly attributable to war and famine. Factors such as poverty, deteriorated health facilities and destruction of infrastructure are the consequence of the lack of suitable sanitary practices and proper hygiene, especially in refugee camps, that adversely promote infectious diseases to migrants, particularly among vulnerable children. Generally, the gastrointestinal tract is the predilection site for most helminths and protozoa. They are therefore regarded as a serious public-health problem, as they cause malabsorption, malnutrition and blood loss, leading to anaemia or even death. In addition to their health effects, parasitic infections cause physical and mental impairment in children, retard their educational achievements and hinder economic development. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.

Users of BIM tools point to the ability to visualize the final design along with the construction process as a beneficial feature of using BIM. Knowing the construction process in relationship to a facility’s design benefits both safety professionals when planning worker safety measures for a project and designers when creating a project’s design. Success in using BIM to enhance safety partly depends on the familiarity of project personnel with BIM tools and the extent to which the tools can be used to identify and eliminate safety hazards. In a separate, ongoing study, the authors investigated the connection between BIM and safety to document the opportunities, barriers, and impacts. Utilizing an on-line survey of project engineers who work for construction firms together with a comprehensive literature review, the study found those who use BIM feel that it aids in communication of project information and project delivery, both of which have been found to have positive impacts on construction site safety. Further, utilizing the survey results, the authors apply the binary logistic regression econometric framework to better understand the factors that lead to safety professionals believing that BIM increases safety in the work place. In addition, according to the survey results, a large percentage of the engineers who use BIM feel that ultimately it helps to eliminate safety hazards and improve worker safety. The study findings suggest that improvements in safety performance across the construction industry may be due in part to increased use of BIM in the construction industry. © 2017 by the authors; | MDPI Multidisciplinary Digital Publishing Institute | 2313576X | |

In this paper the MHD flow in different cross section microchannels has been numerically investigated with different electromagnetic boundary conditions. Square, rectangular, circular and trapezoidal cross section microchannels have been used to explore the effect of channel geometry on the MHD micropump operation. The study covers a selected range of applied electric currents and magnetic flux to show their effects on MHD flow. Thermal characteristics of MHD flow have been also studied by calculation the temperature distribution through MHD micropump region. The results obtained show a considerable effect of channel geometry, the applied electric and magnetic fields on the velocity and flow rate. The circular cross section micropump gave higher velocity and flow rate compared with other cross sections, and there is a slight increase in temperature due to small effect of Joule heating. © 2017 Karabuk University | Elsevier B.V. | 22150986 | |

This can be achieved through in vivo maintenance of Strongyloides stercoralis in Meriones unguiculatus, but isolating a large quantity of Strongyloides stercoralis to establish the colony from an infected patient is too difficult to achieve. Hence, Strongyloides ratti have been used as a model in human strongyloidiasis research. This study describes a successful establishment and maintenance of Strongyloides ratti infection in experimentally immunosuppressed Wistar rats. Large quantities of filariform (iL3) larvae of Strongyloides ratti for research related to human strongyloidiasis have been harvested following this protocol. Molecular detection method based on PCR using species specific primers was used to confirm the species of the harvested infective larvae (iL3). Additionally, the identification of histopathological lesions confirmed the presence of infective larvae (iL3) in the liver and lungs as a result of an increased parasite burden due to hyperinfection and disseminated disease. This pathological presentation was found to be similar to that reported in Strongyloides stercoralis-infected immunocompromised human subjects. © 2017, Malaysian Society for Parasitology.

The cavity has a hot stationary bottom wall and a cold top lid-driven wall, and all the other walls completing the domain are motionless and adiabatic. The simulations are performed for different Reynolds numbers, Re = 5000, 10,000, 15,000 and 30,000, and for dimensionless rotational speeds of the cylinder, 0 ≤ Ω ≤ 10. The performance of two turbulence methods, Large Eddy Simulation (LES) and Unsteady Reynolds-Averaged Navier-Stokes (URANS), has been evaluated in this research. The flow and thermal fields are studied through flow vectors, isotherm contours and iso-surfaces temperature, as well as through the average Nusselt number (Nuav) and velocity components. The results demonstrate clearly that the flow patterns and the thermal fields are influenced strongly by increasing either the rotating cylinder speed or the Reynolds number. Furthermore, both LES and URANS solutions can capture the essential feature of the primary eddies in the cavity. But this study has shown convincing evidence that only the LES method can predict the structure details of the secondary eddies that have profound effects on the heat transfer behaviour within the enclosure. © 2017 Elsevier Ltd | Elsevier Ltd | 179310 | |

In this paper, a novel fast Fourier transform-coupled machine learning based ensemble model is adopted for advising patients concerning whether they need to take the body test today or not based on the analysis of their medical data during the past a few days. The weighted-vote based ensemble attempts to predict the patients condition one day in advance by analyzing medical measurements of patient for the past k days. A combination of three algorithms namely neural networks, support vector machine and Naive Bayes are utilized to make an ensemble framework. A time series telehealth data recorded from patients is used for experimentations, evaluation and validation. The Tunstall dataset were collected from May to October 2012, from industry collaborator Tunstall. The experimental evaluation shows that the proposed model yields satisfactory recommendation accuracy, offers a promising way for reducing the risk of incorrect recommendations and also saving the workload for patients to conduct body tests every day. The proposed method is, therefore, a promising tool for analysis of time series data and providing appropriate recommendations to patients suffering chronic diseases with improved prediction accuracy. © 2017, Springer International Publishing AG. | Springer Verlag | 3029743 | |

The impact of wetting layer (WL) carrier density, CH time constant, effective intraband relaxation time have been examined. The derived heat capacity for QD structure have (T-1) dependence. It is shown here that both WL carrier density and QD excited state (ES) occupation controls the overall nonlinear contributions. Then inclusion of WL and ES in the CH induces a new equilibrium reached at a faster recovery time. The proposed model yields results in a line with experiments at high carrier density reflecting the efficiency of our model. © 2017 The Authors | Elsevier B.V. | 22113797 | |

Nineteen Uvitellina iraquensis Dronen, Ali &Al-Amura, 2013 from site #1 and 17 specimens from site #2 were fixed with minimal compression for comparisons of morphological characteristics, measurements, morphometric percentages and morphometric ratios commonly used to distinguish species of cyclocoelids. An additional five adult specimens from site #1 were fixed without compression for comparisons. Specimens from site # 1 (n=24) represented only fully-developed, non-senescing adults, while those from site #2 (n=17) could be divided into fully-developed (non-senescing) adults (n=8); younger (smaller, less developed) adults (n=5) and senescing adults (n=4). The following characteristics were relatively consistent, and appeared to be valuable in identifying groups of similar species and distinguishing species in Uvitellina: the presence or absence of the oral sucker; the oral sucker/pharynx width ratio; the posterior extent of the cirrus sac relative to the intestinal bifurcation; the position of the genital pore relative to the pharynx; the position of the testes in the body; the length of the intertesticular space; the length of the posttesticular space; the lateral disposition of the uterine loops; the presence of a posteriorly-directed, tail-like extension off the posterior confluence of the vitelline fields; the posterior extent of the uterine loops relative to the gonads; and the size of fully-developed eggs. It may be beneficial to calculate the percentage that measurements represent relative to the body length to provide insight into the relationship of the size of a structure to increased size of the specimens (growth). Specimens fixed without compression appeared to be less uniform, less symmetrical, shorter, more distorted and the internal details were more difficult to see. © 2017 Magnolia Press. | Magnolia Press | 11755326 | |

This study focused on examining electronic transport through normal metal mesoscopic rings that have one dimension, and suggested how such rings can be employed to design nanoscale AND gate. A double mesoscopic ring was utilized for AND gate operation, every ring was threaded by magnetic flux, and the magnetic flux was considered as the key tuning parameter in the AND gate action. For a particular value of magnetic flux equal to the half of elementary flux-quantum, a logical AND gate operation was used depending on the applied gate voltages. Two gate voltages were externally applied to the lower arm of every ring, which acted as the two inputs of the AND gate. Few relevant patents to the designing and fabrication of quantum logical gates have been reviewed and cited. Methods: All the calculations are based on the time-dependent Hamiltonian model, the steady state is used to obtain the transmission probability. Results: The transmission probability, the current and the noise power of current fluctuations were calculated in the weak-coupling and strong-coupling regimes. Conclusion: This study paved the way for the production of an electronic logic gate. © 2017 Bentham Science Publishers. | Bentham Science Publishers B.V. | 18722105 | |

The maximum current values are measured for zwitterion species. In addition, the current increases with increasing of concentration and scan rate, and decreases with increasing pH. The resulting passivation was studied by spectroscopic analysis such as attenuated total reflection FT infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectroscopy (XPS) and mass spectroscopy (MALDI-TOF). From thin film coatings observed on the electrode surface, peptide bonds are found, and are in favor of electropolymerization of these polar amino acids into poly-L-amino acids in an irreversible way. Scanning electronic microscopy was also used to study the morphology of these electrodeposited L-amino acids. The electrodeposited poly-L-amino acids on Pt electrode were tested as bioinspired transducer for pH sensing purposes. © 2016 Elsevier B.V. | Elsevier Ltd | 2540584 | |

Hollow pultruded GFRP square tubes (125 mm × 125 mm × 6.5 mm) were bonded together using epoxy adhesives to form the beams using 2–4 cells. Concrete with 15 and 32 MPa compressive strengths was used to fill the top cell of the multi-cell beams. These beams were then tested under static four-point bending and their behaviour was compared with hollow beams. The results showed that up to 27% increase in strength was achieved by using multi-cell beams compared to a single cell beam. Filling in the top cell of the beams with concrete enhanced the capacity as well as the stiffness of the beams. The multi-celled GFRP beams filled with concrete at the top cell failed at 38–80% higher load and exhibited 10–22% higher stiffness than their hollow counterparts. The increase in the compressive strength of the concrete infill from 15 MPa to 32 MPa resulted in up to 14% increase in the failure load but did not enhance the flexural stiffness. Finally, the proposed prediction equation which account for the combined effect of shear and flexural stresses showed a good agreement with the experimental results for hollow cells and up to 3 cells of concrete filled beams. The bearing stress equation gave a better estimation for 4-cell filled section. © 2016 Elsevier Ltd | Elsevier Ltd | 2638223 | |

The density matrix theory was used to formulate the system while the orthogonalized plane waves for wetting layer-quantum dot (WL-QD) were considered to state the momentum matrix elements for this system. It is found that the momenta follow the smallest energy difference between states with an obvious overlap of the mediated states. Since WL-QD momenta are small, neglecting WL gives high SONS. Millimeter waves are predicted, and a huge SONS can be obtained by the application of more optical fields, which is important in medical and biological applications. The possibility of changing light speed between subluminal and superluminal was predicted here. This opens the way for many applications like multichannel waveguide-multichannel quantum information processing, real quality imaging, and temporal clock. © 2016 Optical Society of America. | OSA - The Optical Society | 1559128X | |

Recent studies suggested an association between maternal immune response and this disorder. Methods Forty-nine women with autistic children (cases) were studied in comparison with 73 women with normal children (controls). After interviewing for sociodemographic and clinical information, mothers' sera were tested for the presence of antineuronal antibodies. Results Mothers of autistic children had significantly higher seropositivity for anti-Yo antibodies (34.7%) than control women (13.7%), with an (adjusted odds ratio of 2.60 (95% confidence interval, 1.03–6.61; p = 0.044). Similarly, women with autistic children showed significantly higher seropositivity for antiamphiphysin than the control group (40.8% vs. 17.8%), with an adjusted odds ratio of 2.54 (95% confidence interval, 1.07–6.04; p = 0.035). No significant association was found between autism spectrum disorders and maternal anti-Hu antibodies and anti-Ri antibodies, and the history of autoimmune diseases. Conclusion Some maternal antineuronal antibodies may contribute significantly to the risk of childhood autism. © 2016 | Elsevier Ltd | 17264901 | |

This paper introduce background reviewing, and discuss the Iraqi's key institutional & regulatory framework, and introducing the administrative authorities of land and giving brief details of its hierarchy and responsibilities in this respect. Accordingly, this paper explores the Iraqi case within 5 different periods of time to review all those doctrines and decrees that shaped the pre-modern laws of land and land rights by focusing on the main administrative progresses during the implementation of the Iraqi national development. The discussion progresses to deal with the Iraqi current crisis in order to assess the role of Iraqi Land Authorities (ILAs) focusing on their efficiency under the influence of the recent situations. The paper also highlighted a set of the Iraq's complex critical factors, which are believed to be the fundamental considerations for implementing the land tenure and its security and saving the land users’ rights in the Iraqi current case. © 2016 Elsevier Ltd | Elsevier Ltd | 2648377 | |

Novel STM-based conductance measurements combined with quantum transport calculations demonstrate that current-perpendicular-to-the-plane (CPP) junctions have three-orders-of-magnitude higher electrical conductances than their current-in-plane (CIP) counterparts, ranging from 2.10-2 G0 for Ni-DPP up to 8.10-2 G0 for Zn-DPP. The metal ion in the center of the DPP skeletons is strongly coordinated with the nitrogens of the pyridyl coated electrodes, with a binding energy that is sensitive to the choice of metal ion. We find that the binding energies of Zn-DPP and Co-DPP are significantly higher than those of Ni-DPP and Cu-DPP. Therefore when combined with its higher conductance, we identify Zn-DPP as the favoured candidate for high-conductance CPP single-molecule devices. © The Author(s) 2016. | Nature Publishing Group | 20452322 | |

In the proposed system, all the channels are sent and received simultaneously, while the frozen bits of polar codes are used for antenna switching. The results show that a location of the switching code at the noisy frozen bits reduces the performance of the proposed system especially in the case of low signal to noise ratio. To improve the system performance, this work suggests a method to encode the data transmitted through the frozen bits. © 2016 IEEE. | IEEE Computer Society | 21654247 | |

Many healthcare companies have moved their electronic data to the cloud in order to reduce in-house storage, IT development and maintenance costs. However, storing the healthcare records in a third-party server may cause serious storage, security and privacy issues. Therefore, many approaches have been proposed to preserve security as well as privacy in cloud computing projects. Cryptographic-based approaches were presented as one of the best ways to ensure the security and privacy of healthcare data in the cloud. Nevertheless, the cryptographic-based approaches which are used to transfer health records safely remain vulnerable regarding security, privacy, or the lack of any disaster recovery strategy. In this paper, we review the related work on security and privacy preserving as well as disaster recovery in the eHealth cloud domain. Then we propose two approaches, the Security-Preserving approach and the Privacy-Preserving approach, and a disaster recovery plan. The Security-Preserving approach is a robust means of ensuring the security and integrity of Electronic Health Records, and the Privacy-Preserving approach is an efficient authentication approach which protects the privacy of Personal Health Records. Finally, we discuss how the integrated approaches and the disaster recovery plan can ensure the reliability and security of cloud projects. © 2016 Elsevier Ltd | Elsevier Ltd | 104825 | |

In the limit of a narrow filter (λ = 0), the QD-LED equations reduce under some conditions to the equations for a QD-LED with optical feedback, whereas they become the Lang Kobayashi equations in the limit of an unbounded filter width (λ > 0). Through simulations based on the rate equations for a QD-LED with filtered external optical feedback modes, we show that the output’s nonlinear dynamical system attractors can be controlled through the filter parameters: the filter’s spectral width λ and its central frequency Ωm.

It is a novel technique to build net-shaped or near-net-shaped metal components in a layer-by-layer manner via applying metal wire and selection of a heat source such as laser beam, electron beam, or electric arc. It is a manufacturing method used for production of complex featured and large-scaled parts, especially in aerospace and metal-die industries. This method can lower the cost of fabricated parts by reducing further machining and finishing processes and shortening lead time. This article presents a comprehensive literature review on shaped metal deposition, and it mainly aims to highlight some of the areas which were reported by the researchers in this field to give an extensive overview of shaped metal deposition processes, classification of its methods, and their applications. The presented literature review covers extensive details on microstructure, mechanical properties, and residual stresses induced in the metallic parts produced by various shaped metal deposition techniques as well as fabrication of dual-material parts. Additionally, grain refinement of the deposition morphologies using various techniques, especially the arc pulsation process, was mentioned. This study demonstrates that shaped metal deposition method using wire can be considered as a distinctive low-cost method for fabricating large-scaled components due to high deposition rates, high efficiencies, and dense part production capabilities. However, the accuracy and surface finish are less compared to laser and electron beam melting methods. © IMechE 2015. | SAGE Publications Ltd | 9544054 | |

The governing equations for both fluid flow and heat transfer are solved by using the finite volume method (FVM). The bottom wall of the enclosure is heated while the upper wall is cooled at lower temperature and the other two sidewalls are adiabatic. Four types of nanofluids (Al2O3, CuO, SiO2, and TiO2 with pure water) with nanoparticle volume fraction (ϕ) in the range of 1–4% and nanoparticle diameter in the range of 25–70 nm were used. This investigation covers Richardson number and Reynolds number in the ranges of 0.1–10 and 100–1200, respectively. The trapezoidal lid-driven enclosure was studied for different rotational angles (Φ) in the range of 30°–60°, different inclination sidewalls angles (γ) in the range of 30°–60° and various aspect ratios (A) ranged from 0.5 to 2. This investigation is also examined the opposing and aiding flow conditions. The results show that all types of nanofluids have higher Nusselt number compared with pure water. It is found that SiO2–water has the highest Nusselt number followed by Al2O3–water, TiO2–water, and CuO–water. The Nusselt number increases as the volume fraction increases but it decreases as the diameter of the nanoparticles of nanofluids increases. The Nusselt number increases with the decrease of rotational angle and inclination angle from 30° to 60° and with the increase of aspect ratio. The results of flow direction show that the aiding flow gives higher Nusselt number than the opposing flow. © 2016 Elsevier Ltd | Elsevier Ltd | 7351933 | |

Effects of separation flow and nanofluids on thermal performance for laminar range presented experimentally and numerically in this review. The augmentations of heat transfer with fluid and nanofluid flow through sudden expansion, over backward and forward facing step, and rib channels have been concerned. The experimental results showed good agreement with numerical results and indicated the effects of separation flow and nanoparticles on augmentation of heat transfer rate. The results showed increase in Nusselt number with increase of Reynolds number, step height, and number of ribs. It was detected that by increasing the nanoparticle volume concentrations of nanofluids, improves the heat transfer coefficient. Also different nanoparticles used in the literature investigations are based on thermal conductivity where enhancement of heat transfer rate was obtained significantly. © 2016 Elsevier Ltd | Elsevier Ltd | 7351933 | |

So that a compressive residual stresses are generated to a certain radial depth at the cylinder wall. The objective of the present study, is to investigate the effect of autofrettage process on radial, circumferential and total stresses by using von Mises yield criteria. Numerical simulation carried out on ABAQUS software to investigate the stresses distribution and calculate the autofrettage radius. The results reveal that, the autofrettage process of thick-wall cylinder lead to decrease the hoob and maximum von Mises stresses and relocate them from the inner surface of the cylinder to somewhere along it's thickness. The reduction in maximum stresses is strongly depend on autofrettage pressure, it was varying from ( 3.6% at Pautofrettage = 105 MPa to 19.2% at Pautofrettage = 130 MPa ) Also, it has been found , there is no effect of number of autofrettage stages on both of maximum von Mises stress and autofrettage radius. © IAEME Publication. | IAEME Publication | 9766340 | |

Nineteen unrelated strains of L monocytogenes were recovered from approximately 1300 food and food processing environmental samples collected from 2007 to 2011 as part of the U.S. Food and Drug Administration pathogen surveillance program. The L. monocytogenes environmental isolates were characterized by serotyping, subtyping, and identification of antimicrobial resistance determinants. The serovars of L monocytogenes were 1/2a, 4b, and 1/2b. PFGE using Ascl digested total DNA showed genetic diversity; there were 10 PFGE pulse-types and 5 PFGE groups. All strains except one strain were susceptible to ampicillin, erythromycin, vancomycin, ciprofloxacin, and chloramphenicol but resistant to extended-spectrum cephalosporins (ESC). The environmental strains were predominantly resistant to streptomycin and tetracycline. No strain was resistant to 3 or more antimicrobial classes. All tetracycline-resistant strains were serotype 1/2a, and only tetM was amplified from the chromosomal DNA. This study, which reports the genetic diversity and antimicrobial resistance of foodborne L monocytogenes, may be useful in food safety control programs to reduce the risk of transmission of L monocytogenes to food products.

In this study, the elastic properties of the pultruded glass fibre-reinforced polymer square sections were evaluated firstly using full-scale with different shear span to depth (a/d) ratios and tested under static four-point bending. Back calculation and simultaneous methods were then employed to evaluate the flexural modulus and shear stiffness and were compared with the results of the coupon tests. Secondly, the full-scale beams were tested up to failure to determine their capacity and failure mechanisms. Finally, prediction equations describing the behaviour of the pultruded glass fibre-reinforced polymer square beams were proposed and compared with the experimental results. The results indicate that the back calculation method gives more reliable values of elastic properties of glass fibre-reinforced polymer profiles. In addition, the behaviour of the beams is strongly affected by the a/d ratios. The shear was found to have a significant contribution on the behaviour of beams with lower a/d ratios while the flexural stress played a major part for higher a/d ratios. The proposed equation, which accounts for the combined effect of the shear and flexural stresses, reasonably predicted the failure load of pultruded glass fibre-reinforced polymer square beams. © The Author(s) 2015. | SAGE Publications Ltd | 219983 | |

The results show that by increasing the Reynolds number leads to enhanced Nusselt number and turbulent kinetic energy of the fluid in the domain. Moreover, both LES and URANS solutions captured the existence of the two primary vortexes (clockwise and anticlockwise). However, the comparisons have demonstrated clearly the ability and accuracy of the LES method in predicting the secondary vortexes in the corners of the cavity. © 2016 Elsevier Ltd. | Elsevier Ltd | 179310 | |

A number of experimental investigations and developments for numerical models have been established to understand the strength enhancement behaviour of the FRP-concrete confined section. This paper aims to investigate the influence of the confinement parameters including the concrete strength and the confining pressure on the strength enhancement of FRP-confined concrete specimens. Investigated data were collected from experimental works performed by the authors as well as results surveyed from state-of-the-art papers carefully selected and reviewed to provide an overview and in-depth knowledge in the development of this strengthening technique. Utilizing 927 experimental data from 127 papers from the literature, a 3-dimensional graph presentation (surface chart) have been utilized to investigate the strength enhancement of the FRP-confined concrete. This new graphing format assisted in demonstrating the non-linear influences for each of the parameters investigated on the confinement parameters on the strength enhancement of FRP-confined section. Unlike the conventional 2-dimensional plot of the confined concrete strength versus the confining pressure (both normalized by the unconfined concrete strength), the 3-dimensional graphing approach introduced in this paper is found to provide more information about the strength enhancement. Utilizing a Gauss surface fitting function, a refined enhancement ratio expression incorporating the individual influence of the confinement parameters is proposed in the paper and experimentally evaluated. © 2016 Elsevier Ltd | Elsevier Ltd | 9500618 | |

A systems approach to construction safety enables considering: multiple project elements simultaneously; connections between different elements; and all system elements affected by safety risk. This paper describes recent and current research to conceptualize a typical building project in terms of connections between workers, activities, and design elements, and to verify and analyze impacts of the design and worker interactions on worker safety. Prior research provides the basis for a network tying the design elements, construction activities, and work crews on a typical building project together along with the extent of interaction between each of the system elements in terms of safety. In conjunction with this systems approach, the researchers propose a concept for viewing and managing construction safety through four different types of connections, or "degrees of connectivity," between the different workers, activities, and design elements in the system. The degrees of connectivity are defined as: interacting with the design element during its construction (DoC #1); interacting with the design element in its final form to attach another component to it (DoC #2) or by working in the vicinity of it (DoC #3); and indirectly interacting with the design element through another worker (DoC #4). To support and verify the presence of the concept in practice, the researchers conducted a survey of construction personnel. The survey results confirm that the four different degrees of connectivity are present and felt during construction operations, and indicate that attention should be given to all design elements, activities, and workers to which a worker is "connected". According to the survey respondents, DoC's #1 and #2 are recognized as the most widely present on construction sites. Eighty percent of the respondents believe that the design element has a moderate or greater impact on worker safety while it is being constructed. These initial research steps provide the starting point for continuing study that aims to develop and demonstrate the degrees of connectivity concept linking workers and design elements, with the goal of understanding how to design a project and work operations in order to improve safety during construction. © 2015 Elsevier Ltd.

The batch experiments were conducted at three different TWAS/RS (volume basis) ratios of 1:3, 1:1 and 3:1, respectively. Furthermore, the modified Gompertz model was introduced to predict the biogas yield and evaluate the kinetic parameters. The highest biogas production (409.2 L/kg VSadded) was achieved from co-digestion of TWASthermo-alkaline and RSNaOH at mixing ratio of 1:1, which is greater by 42.2% and 5.9% than that of digesting TWASthermo-alkaline, and RSNaOH alone, respectively. The highest VS removal rate was obtained from the co-digestion of TWASthermo-alkaline and RSNaOH at mixing ratio of 1:3, which is greater by 55.8% and 14.0% than those of mono-digestion. The modified Gompertz model (R2: 0.993-0.998 and 0.993-0.999 for mono- and co-digestions, respectively) showed a good fit to the experimental results and the estimated parameters indicating that the pretreatments and co-digestion of substrates markedly improved the biogas production rate. © 2016 Elsevier Ltd. | Academic Press | 3014797 | |

Using Feynman diagram, the relation of SONS for sum frequency generation was stated. Two cases were studied, which are the interband (IB) and intersubband (ISB) transitions with the consideration of the QD inhomogeneity, which is shown to be important in SONS calculations. For the ISB case, a resonance near 92 μm was predicted, which is important for infrared applications. Energy subbands and momentum matrix elements are shown as the main factors controlling SONS. It was found that adding some detuning to the pump will extend the wavelength by 45 μm which might applicable for Terahertz (THz) applications. Double resonance was shown to blue shifts the wavelength. © 2016 Elsevier B.V. All rights reserved. | Elsevier | 15671739 | |

The expression for modeling state of the network router interface is used for representing the average packet delay as time-varying function. The conditions of ensuring QoS for the set of metrics as the packet rate and average delay are expressed. The novelty of the model is that the network metric is a function of time, and it takes into account that the average queue length and average packet delay take their limit values after convergence time. The results of the research demonstrated that the use of the dynamic tensor model allows ensuring QoS requirements more precisely. © 2016 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The underlying dynamics is affected by a sidle node, which returns to an elliptical shape when the wetting layer (WL) is neglected. Both filter width and time delay change the appearance of different dynamics (chaotic and mixed mode oscillations, MMOs). The results agree with the experimental observations. Here, the fixed point analysis for QDs was done for the first time. For QD-LED with FOF, the system transits from the coherence collapse case in conventional optical feedback to a coherent case with a filtered mode in FOF. It was found that the WL washes out the modes which is an unexpected result. This may attributed to the longer capture time of WL compared with that between QD states. Thus, WL reduces the chaotic behavior. © 2016 Author(s). | American Institute of Physics Inc. | 218979 | |

Hollow pultruded Glass Fibre Reinforced Polymer (GFRP) square beams (125 mm × 125 mm × 6.5 mm) filled with concrete having 10, 37 and 43.5 MPa compressive strength were tested under static four-point bending. The results indicate that filled GFRP beams failed at a load 100-141% higher than hollow beams and showed 25% increase in stiffness. However, the increase in concrete compressive strength from 10 to 43.5 MPa increased the ultimate load by only 19% but exhibited almost the same flexural stiffness indicating that a low strength concrete is a practical solution to fill the GFRP profiles to be used as beam applications. Moreover, the concrete infill prevented the premature buckling and web crushing of the GFRP tube. The maximum strain measured at failure is similar to the compressive strain determined from the coupon test indicating the effective utilisation of the GFRP material. Finally, Fibre Model Analysis which considered the partial confined stress-strain curve for the concrete infill gave an accurate prediction of the flexural behaviour of the concrete filled GFRP sections. © 2016 Elsevier Ltd. | Elsevier Ltd | 2638223 | |

The range of Reynolds number varied from 75 to 225 with volume fraction on CuO nanoparticles varied from 1 to 4 % at constant heat flux was investigated. Continuity, momentum, and energy equations with finite volume method in two dimensions were employed. Four different configurations of backward-facing step (without obstacle, with obstacle of 1.5 mm, with obstacle of 3 mm, with obstacle of 4.5 mm) were considered to find the best thermal performance. The results show that the maximum augmentation in heat transfer was about 22 % for backward-facing step with obstacle of 4.5 mm and using CuO nanoparticles at Reynolds number of 225 compared with backward-facing step without obstacle. It is also observed that increase in size of recirculation region with increase of height obstacle on the channel wall has remarkable effect on thermal performance. The results also found that increases in Reynolds number, height obstacle, and volume fractions of CuO nanoparticles lead to increase of pressure drop. © 2015, The Author(s). | Springer Nature | 21905509 | |

The presences of phytochemicals, antibacterial and antioxidant activities were investigated. Parts of medicinal plants were extracted with acetone 50%. The extracts were evaluated for antibacterial activity using the disc diffusion method, while antioxidant activities were measured using ferric reducing/antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and phytochemical screening was performed using a standard method. Syzygium aromaticum fruit extract exhibited the most activity in the test antioxidants and antibacterial activity when compared with other medicinal plants. Phytochemical analysis revealed that alkaloids, flavonoids, triterpenoids, tannin, and carbohydrates were present in the extracts of Syzygium aromaticum, Mentha piperita, Cinnamomum verum, Pimpinella anisum L. and Zingiber purpurea while saponin and steroids was only present in the Syzygium aromaticum and Zingiber purpurea extracts. The studied medicinal plants have interesting antioxidant properties, antibacterial activity and a phytochemicals composition that could provide scientific evidence for some folk uses in the treatment of diseases and therefore it can provide natural source of antibacterial drugs and antioxidants and can be useful in preventing various diseases including cancer. © 2016, International Journal of Pharmacognosy and Phytochemical Research.

The conservation equations are solved using the finite volume method. The numerical simulations are carried out by standard k-ε turbulence model. Results presented in this paper are for a constant heat flux range of 4000≤q≤16,000W/m2, four nanoparticle volumes (Φ(phonetic)=0.5%, 1%, 1.5%, and 2%), and three expansion ratios (ER=1.25, 1.67, and 2). The Reynolds number is in the range of 20,000≤Re≤50,000. Results reveal that the volume fraction of Al2O3 and Reynolds number significantly affect the surface heat transfer coefficient: an increase in surface heat transfer coefficient was noted when both volume fraction of Al2O3 and Reynolds number were increased for all cases. It is found that the peak of the heat transfer coefficient occurs after the sudden expansion moved far from the step height with the increase of sudden expansion dimensions due to separation flow in case of both pure water and nanofluid. The size of the recirculation zone increases as the Reynolds number and expansion ratio increase. Increasing the nanoparticle of Al2O3/nanofluid tends to enhance the heat transfer coefficient due to nanoparticle heat transport in the base fluid which raises the convection heat transfer. © 2015 Elsevier Ltd. | Elsevier Ltd | 7351933 | |

Solar ponds can be an effective way of capturing and storing this energy. A new theoretical model for a heat transfer in a salinity gradient solar pond has been developed. The model is based on the energy balance for each zone of the pond; three separate zones have been considered, namely the upper convective zone, the lower convective zones, as well as the non-convective zone. The upper and lower zones are considered to be well mixed, which means the temperatures in these zones are uniform. The model shows that the temperature in the storage zone can reach more than 90 °C during the summer season whereas it can be more than 50 °C in winter if the pond is located in the Middle East. In addition, the time dependent temperature for the three layers has been found. Furthermore, it is concluded that heat loss from the pond's surface occurs mainly by evaporation, in comparison to convection and radiation. Heat loss to the ground has been calculated by using three different equations. It was found that the perimeter of the pond has a significant effect on heat loss to the ground from a small pond, while its effect is small in the case of large pond. The validity of the model is tested against experimental data for several established ponds; good agreement is observed. © 2015 Elsevier Ltd. | Elsevier Ltd | 0038092X | |

A small change in dopant arrangement can convert graphene from a semiconducting to a semimetallic state. Based on ab initio Density Functional Theory calculations, we discuss the electron structure of BN-doped graphene with Bravais and non-Bravais lattice-type defect patterns, identifying semiconducting/semimetallic configurations. Semimetallic behavior of graphene with non-Bravais lattice-type defect patterns can be explained by a phase cancellation in the scattering amplitude. Our investigation reveals for the first time that the symmetry of defect islands and the periodicity of defect modulation limit the phase cancellation which controls the semimetal-semiconductor transition in doped graphene. | Nature Publishing Group | 20452322 | |

Accurate measurement techniques using conventional Time of Arrival (ToA), Time Difference of Arrival (TDoA), Angle of Arrival (AoA) and Received Signal Strength Indicator (RSSI) can be adopted to enhance localization accuracy. However, with the introduction of MIMO to increase spectral efficiency, the techniques will not be very precise in term of localization error. In this paper, we propose an effective Adaptive Mutation based Artificial Bee Colony Algorithm (AMABC) optimization algorithm to reduce the BER (Bit Error Rate). Moreover, beam forming and equalization of the localization error is also computed for varying the number of nodes. The performance is assessed and compared with a GA algorithm in term of elapsed time and localization error for varying ranging errors up to 30%. The simulation results shown that the AMABC algorithm outperform GA algorithm in all simulation cases. © Research India Publications. | Research India Publications | 9734562 | |

However, most pultruded GFRP sections fail prematurely without utilising their high tensile strength due to their thin-walled sections. As a result, several hybrid systems made out of GFRP profiles and concrete as a filler material have been proposed in order to enhance their structural performance. Most of these studies utilised high strength concrete wherein the additional cost does not justify the enhancement in the stiffness and strength of the infilled GFRP profiles. This paper presents an experimental investigation on the effect of the compressive strength of concrete infill on the flexural behaviour of beams with a view to determine a lower cost infill for GFRP profiles. Pultruded GFRP square beams (125 mm x125 mm x 6.5mm) were filled with concrete having 10, 37 and 43.5 MPa compressive strength and tested under static four-point bending. The results showed that the capacity of the filled beam sections increased by 100 to 141% than the hollow sections. However, the compressive strength of the concrete infill has no significant effect on the flexural behaviour of the beams. The increase in concrete compressive strength from 10 to 43.5 MPa increased the ultimate moment by only 19% but exhibited an almost same flexural stiffness indicating that a low strength concrete is a practical solution to fill the GFRP profiles.

However, pretreatment of lignocellulosic materials is essential to facilitate enzymatic hydrolysis and improve sugar yield. The objective of this study is to evaluate the effect of acid or alkali during microwave-assisted pretreatment of dragon fruit foliage (DFF) that would make hydrolysis process more efficient. In the present study, distilled water and three chemicals were examined for their effects on releasing monomeric sugar during microwave treatment. Microwave-assisted pretreatment namely microwave-distilled water (M-H2O) (control); microwave-sulfuric acid (M-H2SO4); microwave-sodium hydroxide (M-NaOH); and microwave-sodium bicarbonate (M-NaHCO3) pretreatment were performed using 5% (w/v) of DFF as substrate at 800 watt microwave power for 5 minutes exposure time. Highest yield of monomeric sugar was found at 15.56 mg/g using M-NaOH pretreatment at 0.1N NaOH. For M-H2SO4 pretreatment, 0.1N H2SO4 produced 8.2 mg/g of monomeric sugar. Application of M-NaHCO3 pretreatment using 0.05N NaHCO3 solution released 6.45 mg/g of monomeric sugar. While, soaking DFF in distilled water and subjecting to microwave irradiation released 6.6 mg/g of monomeric sugar. Treatments with the lowest concentration (0.01 N) of the three chemicals released only small quantities of total monomeric sugars and less than that with distilled water. The changes in the physical structure of DFF prior to and after the microwaveassisted pretreatment are also reported. | Universiti Putra Malaysia | 19854668 | |

Watson, D., Strathclyde Institute of Pharmacy and Biomedical Sciences, University of Strathclyde, The John Arbuthnott Building, 161 Cathedral Street, Glasgow, G4 0RE, United Kingdom | Ten physically active subjects underwent two cycling exercise trials. In the first, aerobic capacity (VO2max) was determined and the second was a 45 min submaximal exercise test. Urine samples were collected separately the day before (day 1), the day of (day 2), and the day after (day 3) the submaximal exercise test (12 samples per subject). Metabolomic profiling of the samples was carried out using hydrophilic interaction chromatography (HILIC) coupled to an Orbitrap Exactive mass spectrometer. Data were extracted, database searched and then subjected to principle components (PCA) and orthogonal partial least squares (OPLSDA) modelling. The best results were obtained from pre-treating the data by normalising the metabolites to their mean output on days 1 and 2 of the trial. This allowed PCA to separate the day 2 first void samples (D2S1) from the day 2 post-exercise samples (D2S3) PCA also separated the equivalent samples obtained on day 1 (D1S1 and D1S3). OPLSDA modelling separated both the D2S1 and D2S3 samples and D1S1 and D1S3 samples. The metabolites affected by the exercise samples included a range of purine metabolites and several acyl carnitines. Some metabolites were subject to diurnal variation these included bile acids and several amino acids, the variation of these metabolites was similar on day 1 and day 2 despite the exercise intervention on day 2. Using OPLS modelling it proved possible to identify a single abundant urinary metabolite provisionally identified as oxo-aminohexanoic acid (OHA) as being strongly correlated with VO2max when the levels in the D2S3 samples were considered. © 2016 by the authors;. | MDPI AG | 22181989 | |

It is assumed that the prey is a stage structure population consisting of two compartments known as immature prey and mature prey. It has a refuge capability as a defensive property against the predation. The existence, uniqueness, and boundedness of the solution of the proposed model are discussed. All the feasible equilibrium points are determined. The local and global stability analysis of them are investigated. The occurrence of local bifurcation (such as saddle node, transcritical, and pitchfork) near each of the equilibrium points is studied. Finally, numerical simulations are given to support the analytic results. © 2016 Raid Kamel Naji and Salam Jasim Majeed. | Hindawi Limited | 16879643 | |

The current finite element analysis has predicted the concrete temperatures effectively with temperature errors ranged between 0.1°C and 1.7°C. The proposed finite element model was then used to evaluate the distribution of temperature in deep concrete box-girders considering the weather conditions of Gaziantep, Turkey. The weather data including solar radiation, air temperature and wind speed for a hot summer day were recorded from a specially installed weather station in the campus of the University of Gaziantep. The results showed that the AASHTO's gradient model was almost identical with the predicted temperature gradients at the top and the bottom surfaces and along the clear depth of the webs. However, the behavior along the top 1 m was different. © IAEME Publication. | IAEME Publication | 9766308 | |

The aim of this study was to investigate the antioxidant and antibacterial capacities of Myrtus communis leaf and stem. Methanol extracts of Myrtus communis leaf and stem were assessed for its antimicrobial activity. The antibacterial activity was determined using paper disc method against two bacteria namely Staphylococcus aureus and Bacillus cereus. The sensitivity in terms of zones of inhibition of both extract was determined. Gentamicin was used as a standard drug for the study of antibacterial activity. The antioxidant activity was determined by measuring total phenolic content (TPC), ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH). The result showed that the methanol extracts of Myrtus leaf and stem were effective against both the bacteria tested. The leaf extract of Myrtus exhibited a higher antibacterial activity than the stem extract of Myrtus. The acetone extract of Myrtus leaf showed the largest antioxidant TPC, FRAP and DPPH compared with stem extract. A marked antimicrobial and antioxidant activity of Myrtus communis leaf and stem extracts was observed which may be attributed to the presence of phenolic compounds and other phytochemicals. The plants can be used to control infectious diseases and prevent oxidative damage. © 2016, Sphinx Knowledge House. All rights reserved. | Sphinx Knowledge House | 9744290 | |

Such investigation mainly focuses on the expected properties of the doped polymers with different doping ratios of crystal violet (0.01, 0.03, 0.05, 0.07, 0.1) %wt. This is indicated by the electron transfer between the dopants and both polymers, which clearly shows the appearance of oxidation - reduction peaks accompanied log increase in electrical current Ip as applied potential changes. The heights of Ip oscillate due to the change in scan rate, n. The results of linear of relationships between Ip with n1/2 indicated that the electron transfer was a process of one electron transfer. | Scholars Research Library | 0975413X | |

In this work, a microwave-diluted sulfuric acid pretreatment was applied prior to enzymatic hydrolysis of sago palm bark (SPB). Characterization of the solid fraction was completed before and after the pretreatment process. Analysis of SPB ash showed a presence of 6.8% silica. There was a 32% reduction in lignin content, an increased crystallinity from 29% to 47%, and clear damage and fragmentation to the surface structure of SPB after the pretreatment. Inhibitors were not detectable in the liquor after the microwave-acid pretreatment. The enzymatic hydrolysis of SPB was employed by adding 6 to 42 FPU/g of cellulase and 50 U/g of β-glucosidase to identify the optimal cellulase loading at fixed β-glucosidase loading. The maximum total monomeric sugar yield and total reducing sugar (using DNS method) at 77 mg/g and 378 mg/g were achieved using 24 FPU/g of cellulose, respectively. Thus, this enzyme loading can be recommended for further microwave-acid pretreatment and enzymatic hydrolysis of SPB. | North Carolina State University | 19302126 | |

The experimental investigations were performed in the Reynolds number range from 5000 to 30000, the heat flux varied from 1000 to 4000 W/m2, and the expansion ratio was maintained at D/d=1, 1.25, 1.67 and 2. The sudden expansion was created by changing the inner diameter of the entrance pipe to an annular passage. The outer diameter of the inner pipe and the inner diameter of the outer pipe are 2.5 and 10 cm, respectively, where both of the pipes are subjected to uniform heat flux. The distribution of the surface temperature of the test pipe and the local Nusselt number are presented in this investigation. Due to sudden expansion in the cross section of the annular pipe, a separation flow was created, which enhanced the heat transfer. The reduction of the surface temperature on the outer and inner pipes increased with the increase of the expansion ratio and the Reynolds number, and increased with the decrease of the heat flux to the annular pipe. The peak of the local Nusselt number was between 1.64 and 1.7 of the outer and inner pipes for Reynolds numbers varied from 5000 to 30000, and the increase of the local Nusselt number represented the augmentation of the heat transfer rate in the sudden expansion of the annular pipe. This research also showed a maximum heat transfer enhancement of 63-78% for the outer and inner pipes at an expansion ratio of D/d=2 at a Re=30000 and a heat flux of 4000W/m2. | Serbian Society of Heat Transfer Engineers | 3549836 | |

Looking at safety from a different standpoint, the authors are working on an ongoing study regarding a concept which they call "Degrees of Connectivity" (DoC). To conduct the study, the researchers applied a mixed-methods approach to improve confidence in the research results that includes: industry surveys, an analysis of OSHA records, and process and behavioral observations on construction sites. Multiple survey questionnaires were distributed to project managers, engineers, workers, and foremen. Survey questions were divided into three groups: demographic, safety, and degrees of connectivity. The collected results at this stage of the research show that there is an impact of one worker on other workers regarding safety achievement. Moreover, the results reveal connectivities between workers and the design elements within the project being constructed. A scheme to represent the DoC concept has been established based on the study results and the identified interactions between workers and design elements. The DoC concept contributes to current practice by providing designers and constructors with a framework to assess the impact of the design on construction personnel before construction commences. © ASCE. | American Society of Civil Engineers (ASCE) | | |

Building information modelling (BIM) and 3D laser scanning are two examples of rapidly evolving technologies that can help achieve this purpose. Researchers are conducting an ongoing study to: (1) determine the general knowledge state for these technologies among construction project management personnel; (2) determine the benefits and shortcomings of these technologies; (3) explore barriers to and enablers of these technologies and compare the barriers and enablers with those found in earlier studies; and (4) identify awareness and demand statuses of using these technologies. The study utilizes a survey questionnaire distributed among project management personnel. The research results show that there is generally a high level of knowledge about BIM among construction management personnel; however, this is not the case with 3D laser scanning. BIM and 3D laser scanning help in resolving issues on construction jobsites and there is increased demand for using BIM in the industry; however, amongst the owners surveyed, there is not as much demand for using 3D laser scanning.

Inhomogeneity in the QD system is included which is not included in earlier studies of Kerr nonlinearity in QDs. Possibilities of subluminal and superluminal light propagation and switching between them are examined. Double tunnelling is shown to obtain giant Kerr dispersion compared with single tunnelling. High conduction- and low valence-band tunnelling components are required to obtain high Kerr dispersion. Working with one tunnel component reduced Kerr dispersion and switching between subluminal and superluminal can be obtained and the EIT window can be removed. © 2016 . | Elsevier | 22113797 | |

A strong correlation between the two annealing processes was observed, leading to a profound effect on the performance of CdS/CdTe thin film solar cells. Atomic force microscopy and Raman spectroscopy show that the iTAP in the optimal processing window produces considerable CdTe grain growth and improves the CdTe crystallinity, which results in significantly improved optoelectronic properties and quantum efficiency of the CdS/CdTe solar cells. A power conversion efficiency of up to 7.0% has been obtained on thin film CdS/CdTe solar cells of absorber thickness as small as 0.75 μm processed with the optimal iTAP at 450°C for 10-20 min. This result illustrates the importance of controlling microstructures of CdTe thin films and iTAP provides a viable approach to achieve such a control. © 2016 Alaa Ayad Al-mebir et al. | Hindawi Publishing Corporation | 16878108 | |

The objective of this study was to formulate papaya leather from locally grown papaya using natural ingredients like pectin, honey and citric acid. The fresh fruits were pureed and mix with natural ingredients, and dried in an oven at 60°C for 12 hours. The physicochemical properties and antioxidant activity were determined. The results showed that fruit leather made from Hongkong cultivar is significantly (P<0.05) higher in sensory parameters as well as physicochemical properties and antioxidant activity. The phenolics content and antioxidant activity increased by process of drying the fruit leather compared to fresh fruits in both papaya cultivars. Therefore, the consumer requirements for healthy and safe food products were respected. | Chiriotti Editori | 11201770 | |

Using this system, the thickness of the CdTe absorber layer is varied across a single sample from 1.5 μm to 0.75 μm. The effects of thickness on CdTe grain morphology, crystal orientation, and cell efficiency were investigated with respect to different postprocessing conditions. It is shown that the thinner CdTe layer of 0.75 μm obtained the best power conversion efficiency up to 5.3%. The results of this work shows the importance that CdTe grain size/morphology relative to CdTe thickness has on device performance and quantitatively exhibits what those values should be to obtain efficient thin-film CdTe/CdS solar cells fabricated with pulsed laser deposition. Further development of this combinatorial approach could enable high-throughput exploration and optimization of CdTe/CdS solar cells. © 2016 Ali Kadhim et al. | Hindawi Publishing Corporation | 16879384 | |

This is not surprising given the significant challenges in aerosolising stem cells, particularly given their susceptibility to damage under the large stresses involved in the nebulisation process. Here, we present promising results using a microfluidic acoustic nebulisation platform that is not only low cost and portable, but also its high MHz order frequencies are effective for preserving the structural and functional integrity of mesenchymal stem cells (MSCs) during the nebulisation process. This is verified through an assessment of the viability, structure, metabolic activity, proliferation ability and genetic makeup of the nebulised MSCs using a variety of assays, including cell viability staining, flow cytometry, reverse transcription and quantitative polymerase chain reaction, and immunophenotyping, thus demonstrating the platform as a promising method for efficient pulmonary stem cell delivery. © 2016 The Royal Society of Chemistry. | Royal Society of Chemistry | 17579694 | |

Nonlinear optical processes results in SONS are discussed, they are: second-harmonic generation (SHG), sum-frequency generation (SFG), difference frequency generation (DFG) and optical rectification (OR). Two types of structures are used the first structure uses the interband transitions in QDs while the second structure uses valence intersubband transitions. SONS relations for SHG, SFG, DFG and OR are derived. A high SONS for the first structure is obtained at long wavelength while a millimeter wavelength is obtained from the second structure which is important in optical communication applications. © 2015, Springer Science+Business Media New York. | Springer New York LLC | 3068919 | |

To improve the scalability of the network the hierarchical approach of the network is used because usage of centralized schemes is very resource-intensive. Due to disagreement of solutions obtained on routers and thus appearance of the link overloading and the subsequent package lost we proposed to use the goal coordination method. The usage of this method allows distributing flows through links without its overloading and improving quality of service and increasing the efficiency of network management. © 2015 Kharkiv National University of Radioelectronics. | Institute of Electrical and Electronics Engineers Inc. | | |

Method: Sixty female mice were divided into five treatment groups, namely, normal saline, corn oil only, T3 only, CPA and CPA + T3. The treatment was given for 30 days, followed by administration of gonadotrophin to induce ovulation. After killing, both ovaries were collected and examined histologically. Results: There was significant reduction in ovarian size in the CPA group compared with the normal group (CPA versus normal, mean area ± SD; 0.118 ± 0.018 vs. 0.423 ± 0.024 cm2; p ‰ 0.005), whilst concurrent administration of T3 with CPA leads to conservation of ovarian size (CPA + T3 vs. CPA, mean area ± SD; 0.285 ± 0.032 vs. 0.118 ± 0.018 cm;be p ‰ 0.005). Ovaries in CPA group showed abnormal folliculogenesis with accompanied reduced ovulation rate, follicular oedema, increased vascularity and inflammatory cell infiltration. These changes were reversed by concurrent T3 administration. Conclusion: Co-administration of T3 with CPA confers protection of ovarian morphology and function in vivo. These findings contribute to the further elucidation of CPA effect on ovary and suggest the potential of T3 use in preserving fertility in chemotherapy. © 2015 SAGE Publications. | SAGE Publications Ltd | 9603271 | |

Fermi 6, Firenze, 50125, Italy | In this work quantum dot light emitting diode (QD-LED) was modeled in a dimensionless rate equations system where it is not done earlier. The model was examined first under bias current without any external perturbation where it exhibits chaotic phenomena since the model has multi-degrees of freedom. Then, it is perturbed by both small signal and direct current modulations (DCM), separately. The system exhibits mixed-mode oscillations (MMOs) under DCM. This behavior was reasoned to continuous states of two dimensional wetting layer (WL) which works as a reservoir to quantum dot (QD) states. QD capture was the dominant rate controlling the dynamic behavior in QD-LED. The nonlinear dynamic behavior of our model is compared very well to the experimental observations in the QD-LED. © 2015 Elsevier Ltd. All rights reserved. | Elsevier Ltd | 9600779 | |

Power conversion efficiency (PCE) of 8.13 % was achieved for this DSSCs device, which is higher than that of DSSCs devices using NiO, RGO, and RGO/NiO-CE (PCE = 2.71 %, PCE = 6.77 % and PCE = 7.63 %). Also, the fill factor of the DSSCs devices using the RGO/MWCNTs/NiO-CE was better than that of other CEs. The electron transfer measurement of cyclic voltammetry and electrochemical impedance spectroscopy showed that RGO/MWCNTs/NiO film could provide fast electron transfer between the CE and the electrolyte, and high electrocatalytic activity for the reduction of triiodide in a CE based on RGO/MWCNTs/NiO in a DSSC. © 2015, The Author(s). | SpringerOpen | 23116706 | |

The simulation results indicated that the performance characteristics of GaN-based quantum-well VCSEL were improved when the AlGaN EBL has been added. The effect of Al mole fraction (x) of the AlxGa1-xN EBL on the GaN-based VCSEL performance ranging from x = 0.15 to x = 0.25 was also studied. At x = 0.15 to x = 0.17, the threshold current was reduced. This reduction in the threshold current is due to the increase in the carrier confinement which is achieved by accumulated much more carrier close to the active region caused by the added AlxGa1-xN EBL. Above the x = 0.17, the threshold current was increased which is attributed to the saturation of the carriers inside the active region that leads to increase in the leakage current. It also was due to that the EBL obstacle the hole flowing in the active region in the x > 0.17. GaN-based VCSEL had the optimum performance with Al0.17Ga0.83N EBL; therefore, the effect of Al0.17Ga0.83N EBL thickness on the GaN-based quantum well VCSEL performance has also been investigated. According to the simulation results, the GaN-based VCSEL had the optimum performance when the EBL thickness was 25 nm. © 2015 Published by Elsevier GmbH. | Springer Science and Business Media B.V. | 304026 | |

In addition, the structure size effect, energy level separation, momentum matrix elements, and pump detuning have been examined, and show that the SONS is increased by using the WL, a low momentum matrix element of WL-QD transition in comparison with interdot transition while QD inhomogeneity reduces SONS to half.

Transmission electron microscopy, scanning electron microscopy images and X-ray diffraction analysis clearly indicated the formation of NiO-NF/MWCNT nanocomposite. The electro-chemical properties of NiO-NF/MWCNT CE are studied by cyclic voltammetry and electrochemical impedance spectroscopy. In particular, current-voltage measurements indicated superior power conversion efficiency (PCE) of 7.63% of the NiO-NF/MWCNT CE compared to 6.72% for the platinum (Pt). The superior photovoltaic performance and low cost of the NiO-NF/MWCNT nanocomposite can be potentially exploited as a new counter-electrode in DSSCs. © 2015 Elsevier B.V.

The effects of volume fraction and step height were compared with the base fluid thermal performance. The obtained results showed an increase in the Nusselt number with the increase in volume fraction of nanofluid, Reynolds number, and step height. A higher local Nusselt number value was found at the second step compared to the first step for all cases. Velocity contours were developed to visualize the recirculation regions before and after the first and second steps. The results also demonstrated enhanced heat transfer with the increase of nanoparticle concentration, and the largest thermal enhancement factor occurred for the highest nanoparticle volume fraction (4%) of Al2O3 considered in this investigation. © 2014 Taiwan Institute of Chemical Engineers. | Taiwan Institute of Chemical Engineers | 18761070 | |

However, due to their relatively low modulus of elasticity and thinned walls, these sections are vulnerable to local buckling which can affect their ultimate strength. This paper investigates experimentally the flexural behaviour of pultruded GFRP beams with shear span-to-depth (a/d) ratios in the range of 1.2 to 6 using full scale pultruded profiles. Failure modes, strength and crack patterns are the main parameters that were examined in this study. The study shows that shear span has a minor effect on the failure modes of the beams while it has a noticeable effect on the ultimate strength. In addition, fibre model analysis was used to validate the experimental results. Comparison between the experimental and the theoretical analysis results shows a good approximation of the moment - deflection behaviour and failure moment of pultruded GFRP beams. © APFIS 2015.

Therefore, it is important to use an accurate method to determine these properties as the behaviour is often governed by deflection rather than strength. In this study, full size pultruded glass FRP (GFRP) beams were used to determine the elastic properties using static four-point bending with different shear span to depth (a/d) ratios. Two different methods-back calculation and simultaneous - were then employed to evaluate the flexural modulus and shear stiffness and were compared with the results of the test using coupon specimens. The results indicate that the elastic properties determined from full scale test using back calculation method can reliably predict the load - deflection behaviour of the pultruded GFRP beams. © APFIS 2015.

Such GRNs are characterized by their scale-free degree distributions and existence of network motifs - i.e., small-node subgraphs that occur more abundantly in GRNs than expected from chance alone. Because these transcriptional modules represent "building blocks" of complex networks and exhibit a wide range of functional and dynamical properties, they may contribute to the remarkable robustness and dynamical stability associated with the whole of GRNs. Here, we developed network-construction models to better understand this relationship, which produce randomized GRNs by using transcriptional motifs as the fundamental growth unit in contrast to other methods that construct similar networks on a node-by-node basis. Because this model produces networks with a prescribed lower bound on the number of choice transcriptional motifs (e.g., downlinks, feed-forward loops), its fidelity to the motif distributions observed in model organisms represents an improvement over existing methods, which we validated by contrasting their resultant motif and degree distributions against existing network-growth models and data from the model organism of the bacterium Escherichia coli. These models may therefore serve as novel testbeds for further elucidating relationships between the topology of transcriptional motifs and network-wide dynamical properties. © 2015 Abdelzaher, Al-Musawi, Ghosh, Mayo and Perkins. | Frontiers Media S.A. | 22964185 | |

In fact, different singularities are different in nature. Some singularities caused by particular configuration, some singularities caused by failure in kinematic model and others caused by architecture of the manipulator. This paper focuses on the architecture singularities analysis. The detection of architecture singularity is very important issue in design process because it causes dangerous situation and lead to ill-condition configuration of parallel manipulator. The quality index used as good index to avoid architecture singularities and obtain on optimal architectural parameters that leading to a good properties for design the manipulator. The effects location of the joints, translation and rotation of the moving platform are analyzed. The technique used for architecture singularity analysis of a 6 DOF parallel manipulator based on neural network algorithm.

In countries like Iraq the use of stone columns is still limited from a practical point of view, chiefly as many other soil conditions are commonly encountered. These include collapsible soils: soils that are prone to relatively rapid volume compressions (through collapse of metastable fabrics) that occur due to the action of load and/or increases in water content. Recent work has opened up the possibility to use stone columns in these soils by the use of encasement, thereby overcoming the impact of loss of lateral support when collapse occurs. Area of potential will be discussed; why stone columns could be beneficial for use in Iraq and how employing them as an alternative to conventional ground improvement techniques in number of Iraqi projects would be cost saving and has other benefits. Also, a review of soil conditions in Iraq will be presented and focusing how to treat collapsible soil by encasing the individual stone column by geofabrics illustrating the scope for developing a reliable design approach which suits Iraqi soils. An evidence of their potential applicability in Iraqi soils will be presented. Moreover, the installation technique, facts regarding failure, factors control the behaviour of encased stone columns, calculation of bearing capacity and settlement and some previous related laboratory work will be reviewed as well as recommendations regarding the proposal work in this field are produced with this paper. | Asian Regional Conference on Soil Mechanics and Geotechnical Engineering | | |

It was studied whether industrial weld-size criteria can produce pull-out failure modes. Based on the failure mechanism of the spot welds in a cross-tension test, a simple analytical model is proposed to predict the critical FZ size to ensure the pull-out failure mode. According to the findings, the sheet thickness, the hardness ratio of the fusion zone to the sub-critical heat-affected zone, the amount of shrinkage voids in the fusion zone and the width of the HAZ are the main controlling factors for the transition from the interfacial to the pull-out failure mode in cross-tension loading. The fusion-zone size was proved to be the key factor controlling the cross-tension and tensile-shear strengths of DP780 resistance spot welds. | Institute of Metals Technology | 15802949 | |

Rectangular adiabatic obstacles mounted behind the expansion region on the upper and lower wall of the channel used. The effects of obstacles length, obstacles thickness, and number of obstacles on flow and thermal fields for different Reynolds number and expansion ratio examined. Three values of expansion ratio equal to 1.5, 1.75, and 2 were used. The choice of values of Reynolds number takes in consideration the symmetry state. The governing equations of continuity, momentum, and energy discretized by using the finite difference formulation and the resulting algebraic equations solved by using Gauss-Seidle iteration method. The obtained results show that the obstacles have a considerable effect on dynamics of the flow and enhancement of heat transfer. In addition, it is found that the heat transfer is enhanced more as the obstacles thickness increases and this trend is decreased as the obstacles length increases. | Serbian Society of Heat Transfer Engineers | 3549836 | |

Watermarking is closely related to Stenography except that it hides information in cover object. Watermarking usually serves the purpose of copyright protection and ownership authentication, for example, watermarking can hide a stego-image inside a visible image and user can retrieve the stego-image and secret image in some way. In this paper, we will integrate two algorithms of information hiding, (steganography) F4 algorithm and (visible image) LSB algorithm to improve the level of protection. The secret image is concealed inside a common image through F4 algorithm and the resultant F4 steg-image is then hidden again as a visible image or watermark inside another image by LSB algorithm. To provide more than one level of protection for the hidden message, we will require additional security level to protect the secret image, which leads to increased complexity of retrieving the secrete image. The results prove the success of system after the secret image is retrieved successfully. The value of MSE, SNR and PSNR is calculated, which refers to an acceptable steganography system. | Massey University | 11785608 | |

Then, subbands of dots with different disk radii and heights were calculated under applied field. The competition between the shift due to confinement by field and the size was shown for subbands. Second-order nonlinear susceptibility in quantum dots (QDs) was derived using density matrix theory which is, then, simulated using the calculated subbands. Both interband (IB) and intersubband (ISB) transitions were discussed. High second-order susceptibility in QDs was predicted. The results show a reduction in the susceptibility with the applied field while the peak wavelength was mainly relates to energy difference between subbands. A good match between theory and laboratory experiments was observed. Laboratory experiments at terahertz region might be possible using valence intersubband which is important in many device applications. © 2015 Elsevier Ltd.

The result showed that the color of the pectin is, soluble in hot and cold alkali and water. The results showed that the pectin of Citrus sinensis induced hypolipidemic effect; it significantly decreased total cholesterol, triglycerides, LDL and VLDL serum levels and significantly increased serum HDL level in hyperlipidemic mice. Pectin could be inhibited lipid parameters by many mechanisms. Accordingly, because of the safety of pectin and its significant hypolipidemic effects, it might be considered as therapeutic alternative in hyperlipidemia. © 2015, Sphinx Knowledge House.

The production of bio-alcohol from lignocellulosic wastes requires pretreatment, hydrolysis and fermentation steps. Pretreatment technologies are aimed to break down the recalcitrant structure of lignocellulosic biomass and release the fermentable sugar in the extraction of sugar process for bio-alcohol production. Microwave-based pretreatment has been considered as one of the promising methods of pretreatment, utilising thermal and non-thermal effects that drive physical, chemical or biological reactions. The advantages of microwave-assisted process such as in waste treatment and food drying by reducing the plant footprint, higher throughput, higher reaction rates, higher yield and purity have increased more interest of late. This paper reviews the recent application of microwave-assisted pretreatment of lignocellulosic material via the combination of microwave pretreatment with other physical and chemical pretreatment methods. The synergistic effect of microwave-assisted pretreatment with other pretreatment methods could enhance the fermentable sugar yield from various feedstocks. Different operating parameters that govern the reducing sugar yields such as biomass loading, microwave intensity, and irradiation time are presented. Formation of inhibitor compounds during microwaved-assisted pretreatment are also discussed. © School of Engineering, Taylor’s University. | Taylor's University | 18234690 | |

Sample solutions to the model were obtained for both analytical analysis and numerical analysis. It is assumed that the capillary pressure is neglected (Morris, 2003). Results are provided for liquid film thickness, total heat flux, and evaporating heat flux distribution. In addition to the sample calculations that were used to illustrate the transport characteristics, computations based on the current model were performed to generate results for comparisons with the analytical results of Wang et al. (2008) and Wayner Jr. et al. (1976). The calculated results from the current model match closely with those of analytical results of Wang et al. (2008) and Wayner Jr. et al. (1976).

An experimental investigation was done to evaluate the heat transfer characteristics and the pressure drop of a graphene nanoplatelet (GNP) nanofluid and in numerical study, the finite volume method with standard k-ε turbulence model is employed to solve the continuity, momentum, energy and turbulence equations in three dimensional domains. The thermal conductivity and viscosity of the GNP nanofluids at concentrations of 0.025, 0.05, 0.075, and 0.1 wt% were measured prior to the heat transfer experiments. The heat transfer and the pressure drop within the flowing base fluid (distilled water) were measured and compared with the corresponding data from the correlations and numerical study. The data were satisfied within a 5% error and 2% error for the numerical work. The effects of the nanoparticle concentration and the heat flux on the enhancement of the heat transfer turbulent flow condition are presented. The Nusselt number (Nu) of the GNP nanofluid was higher than the base fluid by approximately 3-83% and increased as the flow rate and the heat flux increased. However, the increase in the pressure drop ranged from 0.4% to 14.6%. Finally, the results reveals that the GNP nanofluids could function as a good and alternative conventional working fluid in heat transfer applications. © 2014 Elsevier Ltd.

In this work, we employed two different strategies to mechanically stress cancer cells. The cancer and healthy cell populations were treated either with mechanical stress delivered by a micropump (fabricated by deep X-ray nanolithography) or by ultrasound wave stimuli. A specific down-regulation of Major Histocompatibility Complex (MHC) class I molecules expression on cancer cell membrane compared to different kinds of healthy cells (fibroblasts, macrophages, dendritic and lymphocyte cells) was observed, stimulating the cells with forces in the range of nano-newton, and pressures between 1 and 10 bar (1 bar=100.000 Pascal), depending on the devices used. Moreover, Raman spectroscopy analysis, after mechanical treatment, in the range between 700-1800 cm-1, indicated a relative concentration variation of MHC class I. PCA analysis was also performed to distinguish control and stressed cells within different cell lines. These mechanical induced phenotypic changes increase the tumor immunogenicity, as revealed by the related increased susceptibility to Natural Killer (NK) cells cytotoxic recognition. © 2014 La Rocca et al. | Public Library of Science | 19326203 | |

Governments, particularly those in developed countries, boast about the efficiency of their electronic systems. Meanwhile, most agencies in developing countries, such as Iraq, lack the advantages provided by new technologies. Therefore, this study aims to discover the limitations of e-health services in developing countries through a literature review, as well as establish an effective system that allows information exchange between the main office and its branches in the local government. Considering the health-related importance of an Health Electronic Record (HER) System, this study designs a system that connects all branch offices with the main office in the center of the province. The development of techniques to improve time and cost management, data handling, decision making, and interactions between agencies is indispensable. The proposed system is expected to improve the quality of service, which allows one branch of a local government to generate up to dozens of files in different locations. Ultimately, this system will assist the local government of Dhi-Qar Province in converting these files into one secure and accessible database. © 2014 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

Turbulence was modeled using the shear stress transport K-ω model. Simulations were performed for Reynolds numbers ranging from 10,000 to 40,000, heat fluxes from 1,000 to 10,000 W/m2, and nanoparticle volume fractions of 0.00% to 0.25%. The two-dimensional governing equations were discretized with the finite volume method. The effects of nanoparticle concentration, shear force, heat flux, contraction, and turbulence on the hydraulics and thermal behavior of nanofluid flow were studied. The model predictions were found to be in good agreement with previous experimental and numerical studies. The results indicate that the Reynolds number and FMWCNT volume fraction considerably affect the heat transfer coefficient; a rise in local heat transfer coefficient was noted when both Reynolds number and FMWCNT volume fraction were increased for all cases. Moreover, the contraction of the channel passage leads to the formation of two recirculation regions with augmented local heat transfer coefficient value. © 2014 Taylor and Francis Group, LLC. | Taylor and Francis Ltd. | 10407782 | |

The governing nonlinear magnetohydrodynamic (MHD) equations in induction-free situations are derived in the framework of MHD approximations and solved numerically using the finite-difference technique. The critical values of Reynolds number (based on upstream mean velocity and channel height) for symmetry breaking bifurcation for a sudden expansion channel (1:4) is about 36, whereas the value in the case of the smooth expansion geometry used in this work is obtained as 298, approximately (non-magnetic case). The flow of an electrically conducting fluid in the presence of an externally applied constant magnetic field perpendicular to the plane of the flow is reduced significantly depending on the magnetic parameter (M). It is found that the critical value of Reynolds number for smooth expansion (1:4) is about 475 for the magnetic parameter M = 2. The separating regions developed behind the smooth symmetric expansion are decreased in length for increasing values of the magnetic parameter. The bifurcation diagram is shown for a symmetric smoothly expanding channel. It is noted that the critical values of Reynolds number increase with increasing magnetic field strength. © 2014 Chinese Physical Society and IOP Publishing Ltd. | Institute of Physics Publishing | 16741056 | |

Food and Drug Administration, Jefferson, AR, United States | Salmonella infection is one of the major foodborne illnesses in the United States. Several Gram-negative bacterial pathogens, including Salmonella Typhi, produce cytolethal distending toxin (CDT), which arrests growth, induces apoptosis of infected host cells and extends persistence of pathogenic bacteria in the host. The aim of this study was to characterize the functionality of CDT (cdtB, pltA and pltB) from nontyphoidal Salmonella isolates. Fifty Salmonella enterica serovar Javiana isolates from food, environmental, and clinical samples were screened for cdtB, pltA, and pltB genes by PCR, and all were positive for all three genes. Nucleotide sequence analysis of all amplified PCR products showed 100% identity to S. Typhi cdtB. To understand the roles of CdtB, PltA, and PltB in S. Javiana, cdtB, pltA, and pltB deletion mutants were constructed using a lambda Red-based recombination system. In vitro-cultured HeLa cell lines were infected with a wild-type strain and its isogenic {increment}cdtB, {increment}pltA, and {increment}pltB to determine whether the strains of S. Javiana are responsible for invasion and cytolethal distending intoxication, including cell cycle arrest, cytoplasmic distension, and nuclear enlargement of host target cells. The results showed that HeLa cells infected with S. Javiana wild type were arrested in G2/M and had distended cytoplasm and nuclei that were larger than those infected with S. Javiana {increment}cdtB and {increment}pltA strains. The S. Javiana {increment}pltB strain retained the ability to induce cytoplasmic distension and cell cycle arrest, whereas the complemented {increment}cdtB and {increment}pltA S. Javiana strains showed activity like the wild-type strains. CdtB and pltA from S. Javiana had apparent effects on the distension of both cytoplasm and nucleus as well as cell cycle arrest of HeLa cell lines after 72 h of infection. Our data show a significant difference between the wild-type cdtB strain and its isogenic {increment}cdtB for invasion of the cell lines. Therefore, CdtB produced from S. Javiana strains may play an important role in pathogenesis in host cells. © 2014.

Contrary to the previous studies performed up to now with diluted l-alanine, the electrochemical process generated here results in a completely different situation. The oxidation on smooth platinum was carried out by electrochemical quartz crystal microbalance (EQCM) coupled to cyclic voltammetry technique. The effects of concentration, scan rate, and pH (zwitterion at pH = 6 and alkaline media at pH = 13) on potential values were examined. Glassy carbon and smooth gold electrodes showed the same behavior as on smooth platinum electrode. Spectroscopic analysis such as attenuated total reflectance FT infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the resulting thin film coatings. The presence of peptide bonds is clearly highlighted. DFT modelization of poly(alaninate) strand on Pt(001) coupled to spectroscopic measurements are in favor of l-alanine electropolymerization into poly-l-alanine in an irreversible way. Due to its proton receptor behavior, electrosynthesized poly-l-alanine on smooth platinum electrode was tested as a whole solid transducer for pH sensing. © 2014 American Chemical Society. | American Chemical Society | 19327447 | |

In contrast to a full martensitic microstructure predicted by the Schaeffler and Balmforth diagrams, a ferrite–martensite microstructure was observed in the fusion zone. The formation of ferrite phase in the fusion zone can be attributed to the rapid cooling rate of resistance spot welding, which suppresses the post-solidification ferrite–austenite transformation. The grain growth and martensite formation were main metallurgical features of the heat affected zone of ferritic stainless steel side. Microstructure gradient of heat affected zone in dual phase steel side was dictated by martensitic transformation.

Iraqi public and private organizations have problem to choose the right staff in the right position within the right time. The issues of choosing right person led to first administrative corruption, second waste the effort, third discarded the public money, fourth made the government less effective and fifth less efficiency government. Recently, Data warehouse is used to provide reports for public and private organizations' human resources. The reports and analysis that data warehouse provide can help the human resource personnel to select the right person in the right time for the suitable job. Ministry of Higher Education and Scientific Research (MOHESR) in Iraq can apply data warehouse to support its decision making. They can use it also to support human resource system in Iraq. This paper creates data warehouse architecture for human resource systems of public and private organizations which give authorized access for students' information of both public and private universities in Iraq. Moreover, the MOHESR can use this idea to increase its income by allowing the public and private organizations to find the proper staff through annual payment access. © 2014 IEEE. | Institute of Electrical and Electronics Engineers Inc. | | |

The model maps the porous structure to a number of parallel micro-channels of arbitrary but constant cross-sectional shapes which remains uniform along the flow path. The gas permeability is found to follow Klinkenberg's equation. The Klinkenberg's slip factor is obtained as a function of matrix porosity and no-slip permeability as well as gas properties. Results are generalized by assuming an arbitrary polygonal shape for the pores. The proposed methodology is simple to follow and easy to implement. Theoretical predictions are then compared to existing experimental data in the literature to observe good agreement. © 2014 Elsevier Inc. All rights reserved. | Elsevier Ltd | 13594311 | |

In this simulation, three volume fractions of nanofluid (0%, 2% and 4%), a varying Reynolds number from 50 to 200 for the laminar range and 5000 to 20,000 for the turbulent range, an expansion ratio of 2 and constant heat flux of 4000 W/m2 were considered. The results show the effect of nanofluid volume fraction on enhancing the Nusselt number in the laminar and turbulent ranges. The effect of expansion ratio was clearly observed at the downstream inlet region where the peak of the Nusselt number profile was referred to as enhanced heat transfer due to the generated recirculation flow. An increase of pressure drop was evident with an increasing Reynolds number and decreasing nanofluid volume fraction, while the maximum pressure drop was detected in the downstream inlet region. A rising Reynolds number caused an increasing Nusselt number, and the highest heat transfer augmentation in the present investigation was about 26% and 36% for turbulent and laminar range, respectively compared with pure water. © 2014 Elsevier Inc.

The behaviour of axial heat conduction in the separating wall under different conditions is studied. The solution was obtained by solving the continuity and Navier–Stokes equations for the hot and cold fluids by using the pressure-correction method to obtain the velocity distribution, and then the energy equations were solved for the two fluids and the separating wall simultaneously to obtain the temperature distribution. The governing equations are discretized using finite-volume and the hybrid differencing scheme with FORTRAN code was used. Various parameters that can have effect on the axial heat conduction were investigated. The results showed that, the axial heat conduction plays an important role in a parallel flow microchannel heat exchanger and the factors affecting the local and average axial heat conduction are; Reynolds number (Re), thermal conductivity ratio (Kr), hydraulic diameter (Dh), thickness of separating wall (ts) and channel volume. Increasing of Re, Kr and ts leads to an increase in the axial heat conduction while increasing of Dh and channel volume leads to a decrease in the axial heat conduction. © 2013 | King Saud University | 10183639 | |

A phosphite based product, Nutri-phite (3% N, 8.7% P, and 5.8% K) was used as model phosphite formulation for foliar application in winter wheat (Triticum aestivum L). Five field trials were established in the fall of 2009 and 2010 at Perkins, Perry, and Morrison, OK. Treatments encompassed the application of nitrogen (N) at 100 or 75% of crop need and phosphorus at 100 (P 100%) and 80% (P 80%) sufficiency with and without Nutri-phite. Nutri-phite was applied at one and/or two stages of wheat; GS 13 to 14 and GS 49 to 53 at the rate of 433 and 148 g ha-1 P and N, respectively. Grain yield was increased by Nutri-phite treatments, especially at Morrison. Grain P concentration of plots treated with two applications of Nutri-phite ranged from 13 to 55% more than the nontreated and standard NP received plots at Perkins in 2009/10 and Perry in 2010/11. Grain P uptake was increased due to application of Nutri-phite at Perkins in 2009/10 and Morrison and Perry in 2010/11. Combined over three year-locations, Nutri-phite increased grain P concentration by 11.6%. The higher grain P concentration of plots treated with Nutri-phite compared to the other treatments clearly demonstrates its potential in improving P status of wheat grain. © 2014 Muaid S.

To keep these important structures in a safe condition, continuous monitoring must be performed regularly and thoroughly. Small rodent burrows are one of the major defects within levees; however, their early detection and repair helps in protecting levees during flooding events. A set of laboratory experiments was conducted to analyze the polarity change in GPR signals in the presence of subsurface voids and water-filled cavities. Ground Penetrating Radar (GPR) surveys using multi frequency antennas (400. MHz and 900. MHz) were conducted along an 875. meter section of the Lollie Levee near Conway, Arkansas, USA, to assess the levee's structural integrity. Many subsurface animal burrows, water-filled cavities, clay clasts, and metallic objects were investigated and identified. These anomalies were located at different depths and have different sizes. To ground truth the observations, hand dug trenches were excavated to confirm several anomalies. Results show an excellent match between GPR interpreted anomalies and the observed features. In-situ dielectric constant measurements were used to calculate the feature depths. The results of this research show that the 900. MHz antenna has more advantages over the 400. MHz antenna. © 2014 Elsevier B.V. | | 9269851 | |

The extended Poincaré-Lighthill-Kuo perturbation method is used to derive the Korteweg-de Vries equations for MASWs in this three-component plasma. The effects of the magnetic field intensity B0, the ratio of negative ions to positive ions number density δ, and the plasma number density on the phase shift are investigated. It is found that these parameters can significantly influence the phase shifts of colliding MASWs.

Nanofluid is used as a cooling fluid, since the flow and heat transfer have been studied with two types of nanofluids (Diamond-water and Al2O3-water) in addition to the pure water. The volumetric concentration of selected nanofluids has been chosen in range (1-4)%. The comparison of hydrodynamic and thermal characteristics of different fin geometries and cooling fluids has been made under the same value of Reynolds number and constant wall temperature thermal boundary condition, the range of Re used is (100-900) to ensure that, the flow remains in the laminar regime. The results obtained indicated that, using of nanofluid instead of pure fluid as a coolant leads to enhanced heat transfer performance by increasing the amount of heat dissipated but it also leads to increased pressure drop for all fins shapes and nanofluids studied. © 2013 Elsevier Ltd.

The processes consist of agitation as a novel stripping method used to overcome the ammonia toxicity regarding aerobic microorganisms. The NH3-N removal ratio was 93.9% obtained at pH 11.5 and a gradient velocity (G) 150s-1 within a five-hour agitation time. By poly ferric sulphate (PFS) coagulation followed the agitation process; chemical oxygen demand (COD) and biological oxygen demand (BOD5) were removed at 70.6% and 49.4%, respectively at an optimum dose of 1200mgL-1 at pH 5.0. The biodegradable ratio BOD5/COD was improved from 0.18 to 0.31 during pretreatment step by agitation and PFS coagulation. Thereafter, the effluent was diluted with sewage at a different ratio before it was subjected to sequencing batch reactor (SBR) treatment. Up to 93.3% BOD5, 95.5% COD and 98.1% NH3-N removal were achieved by SBR operated under anoxic-aerobic-anoxic conditions. The filtration process was carried out using sand and carbon as a dual filter media as polishing process. The final effluent concentration of COD, BOD5, suspended solid (SS), NH3-N and total organic carbon (TOC) were 72.4mgL-1, 22.8mgL-1, 24.2mgL-1, 18.4mgL-1 and 50.8mgL-1 respectively, which met the discharge standard. The results indicated that a combined process of agitation-coagulation-SBR and filtration effectively eliminated pollutant loading from landfill leachate. © 2013 Elsevier Ltd. | | 0956053X | |

However, these XML files have many important features, but these features are not enough to get high performance due to its huge size and complexity of processing. Then to overcome this problem, this paper introduces a new model to enhance data services transfer over internet. The proposed model state, MPI messages are advised to be used instead of XML files to send data services transfer. Also this paper provides a case study and a validation result that explains the benefit of using MPI in contrast to XML files with ROA & REST. © 2014 The Authors. | Elsevier B.V. | 18770509 | |

The thermal effect is included in the web tension dynamics by considering the thermal strain induced by temperature distribution in the web span. The viscoelastic effect is introduced by using a standard linear solid (SLS) model from which a relationship between the applied stress and the resulting strain is obtained. Elevated temperature creep and stress relaxation experiments are conducted on several web materials used in an industrial web processing line to determine the viscoelastic parameters of the utilized viscoelastic model. Model simulations are conducted with the same control systems as those used in an industrial web processing line. Data from model simulations are compared with measured data obtained from the industrial web processing line. Copyright © 2014 by ASME. | American Society of Mechanical Engineers | | |

Chemotherapy is able to kill some cancer cells especially the more rapidly replicating tumor cells, but they were nonspecific, characterized by low therapeutic index and associated with a wide range of side effects. Therefore the anticancer field still searching for treatments to avoid these side effects. The in vitro method was used to investigate the effect of pure sodium valproate on four types of tumor cell lines [HeLa (human cervical cancer cell line, Passages 18-25), Rhabdomyosarcoma (RD, at 75 passages), Ahmad-Majeed- Glioblastoma-Multiform-2005 (AMGM-5, human cerebral glioblastoma multiform at passages 75-84), Ahmed-Mohammed-Nahi-2003 (AMN-3, spontaneous mammary adenocarcinoma at 158 passages) and normal cell line Rat Embryo Fibroblast (REF, at 87 passages)] in different concentrations and at different exposure times by MTT assay. The results showed that sodium valproate induced dose- dependent cytotoxic effects against all the tested cell lines. These effect could be attributed to different mechanisms. Accordingly, sodium valproate should be considered as a good alternative therapy. © 2014-2015, Sphinx Knowledge House. All rights reserved. | Sphinx Knowledge House | 9744304 | |

Here, to investigate the role of lymph node NK cells in disease progression, we analyze frequency, phenotype and functions of NK cells from tumour-infiltrated (TILN) and tumour-free ipsilateral lymph nodes (TFLN) of the same patients. We show an expansion of CD56dimCD57dimCD69+CCR7+KIR+ NK cells in TILN. TILN NK cells display robust cytotoxic activity against autologous melanoma cells. In the blood of metastatic melanoma patients, the frequency of NK cells expressing the receptors for CXCL8 receptor is increased compared with healthy subjects, and blood NK cells also express the receptors for CCL2 and IL-6. These factors are produced in high amount in TILN and in vitro switch the phenotype of blood NK cells from healthy donors to the phenotype associated with TILN. Our data suggest that the microenvironment of TILN generates and/or recruits a particularly effective NK cell subset. © 2014 Macmillan Publishers Limited.

Variations in antioxidant activity and total phenolic content in fruit samples among growing locations were much greater than the variation observed between parts of plant (leaves and fruits), indicating that growing locations plays a more important role than parts of plant (leaves and fruits) in Ficus hispida. The data indicated that the fruits (Tasik Chini) had the highest total phenolic content (285.42 mg/ 100g DW) and antioxidant activity FRAP, DPPH and ORAC (231.02mg/100g DW, 84.03%, and 84.03μmol/g TE) respectively, while leaves (UKM forest) had the lowest total phenolic content (138.59 mg/ 100g DW) and antioxidant activity FRAP, DPPH and ORAC (126.40 mg/100g DW, 70.87%, and 70.87μmol/g TE) respectively. Correlation analyses indicated that there was a linear relationship between antioxidant activity and the total phenolic content in fruits and leaves. However, growing locations play an important role in the total phenol content and antioxidant activity of Ficus hispida leaves and fruits. © 2014, Sphinx Knowledge House.

L. monocytogenes serovars 1/2a and 1/2b strains were dominant as compared to other two serovars 4b and 1/2c strains. The dendrogram of AscI or ApaI-digested PFGE profiles of L. monocytogenes strains was classified into 23 (with 8 groups) or 3 (with 2 groups) different PFGE types, respectively. The AscI-digested groups consisted of the same serovar or food-source. Antimicrobials such as ampicillin, gentamicin, and trimethoprim-sulfamethoxazole are widely used in the treatment of listeriosis. Of the isolates used in this study, NCTR_LM14 and NCTR_LM57 were resistant to several classes of antimicrobials including aminoglycosides, penicillin, tetracycline, glycopeptide and fluoroquinolones. The multi-antimicrobial resistant isolates also showed higher efflux pump activity as compared to the antimicrobial sensitive strains NCTR_LM06 and L. monocytogenes EGD-e. This study demonstrates that L. monocytogenes isolates from various food products are genetically diverse with some isolates being resistant to more than 3 different antibiotic classes. This study also indicates that the efflux pump activity of the antibiotic resistant strains was higher than antimicrobial susceptible strains. Therefore, we propose that the antibiotic resistance observed in these strains may be conferred by the results of a highly active efflux pump system. © 2014. | Elsevier Ltd | 9639969 | |

Three types of aggregate gradation, two types of binder; VG-30 and Polymer modified bitumen (PMB-40) and two types of mixes Bituminous Concrete (BC) and Dense Bituminous Macadam (DBM) are used. Moisture susceptibility tests like retained stability and tensile strength ratio are conducted on Marshall specimens. The static creep test was also conducted for conditioned and unconditioned specimens to observe the effect of moisture on creep behaviour. The results indicate that Marshall stability and flow values are higher in PMB-40 mixes than in VG-30 mixes. Moisture susceptibility of PMB-40 mixes is low when compared with mix using VG-30. The reduction in retained stability, and Indirect Tensile Strength (ITS) and increase in creep are evaluated for finer, coarser and normal gradation of aggregates to observe the effect of gradation on moisture susceptibility of mixes. The retained stability is least affected when compared with other moisture susceptibility parameters. Also, gradation parameters s1 and Gradation Ratio (GR) are introduced in this paper to establish relation between aggregate gradation and moisture susceptibility and permanent deformation. Models are suggested to estimate rut depth from ITS and stability values. © 2014 Korean Society of Civil Engineers and Springer-Verlag Berlin Heidelberg. | Springer Verlag | 12267988 | |

Various annular passage configurations have been used in the reviewed studies, namely circular, ellipse, rectangular, square, triangular, and rhombic annular channels with different fluid and boundary conditions. The effect of eccentricity in both horizontal and vertical directions on heat transfer rate in most numerical and experimental investigations for horizontal and vertical annular passages is studied. The effects of heater length, as well as the Darcy, Prandtl, Reynolds, Grashof and Rayleigh numbers on heat transfer in concentric and eccentric annular passages are also investigated. In case of rotating the inner, outer or both cylinders of the annular cylinder arrangement, the generated secondary flow influences the heat transfer to fluid flow in an annular passage. The effect of nanofluid on the increased enhancement of heat transfer in an annular channel is presented. Related studies on curved, covered annular channels showed augmented heat transfer rate in comparison with straight annular channels. In this review, a good agreement is evident between experimental and numerical data, which could help researchers design thermal systems supported by annular passages with the goal of retarding energy consumption by equipment and machineries in applications that could ultimately contribute to appeasing the global energy crisis. © 2014 Elsevier Ltd. | Elsevier Ltd | 13640321 | |

In this study, Nitrogen-doped graphene (NDG) nanofluids, with varying concentrations of nanoparticles (0.01, 0.02, 0.04, and 0.06 wt%) were prepared using the two-step method in a 0.025 wt% Triton X-100 (as a surfactant) aqueous solution as a base. Stability, zeta potential, thermal conductivity, viscosity, specific heat, and electrical conductivity of nanofluids containing NDG particles were studied. The stability of the nanofluids was investigated by UV-vis over a time span of 6 months and concentrations remain relatively constant while the maximum relative concentration reduction was 20 %. The thermal conductivity of nanofluids was increased with the particle concentration and temperature, while the maximum enhancement was about 36.78 % for a nanoparticle loading of 0.06 wt%. These experimental results compared with some theoretical models including Maxwell and Nan's models and observed a good agreement between Nan's model and the experimental results. Study of the rheological properties of NDG nanofluids reveals that it followed the Newtonian behaviors, where viscosity decreased linearly with the rise of temperature. It has been observed that the specific heat of NDG nanofluid reduced gradually with the increase of concentration of nanoparticles and temperature. The electrical conductivity of the NDG nanofluids enhanced significantly due to the dispersion of NDG in the base fluid. This novel type of fluids demonstrates an outstanding potential for use as innovative heat transfer fluids in medium-temperature systems such as solar collectors. © 2014 Springer Science+Business Media New York. | Kluwer Academic Publishers | 222461 | |

The combination of the high catalytic activity of PANI and outstanding conductivity of GNS/MWCNT improved the photovoltaic performance of the hybrid CE. The cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) showed that the GNS/MWCNT/PANI composite has high catalytic activity for the reduction of triiodide to iodide and low charge-transfer resistance at the electrolyte/electrode interface. Transmission electron microscopy (TEM) images showed that the GNS/MWCNT/PANI-CE has a rough and porous structure and X-ray diffraction analysis confirmed the formation of PANI coating on the surface of the GNS/CNT. In particular, current-voltage measurements showed the superior power conversion efficiency (PCE) of 7.52% of the DSSC based on GNS/MWCNT/PANI-CE compared to the PCE of 6.69% of the DSSC based on Pt-CE. © 2014 Elsevier Ltd. | Elsevier Ltd | 255408 | |

Carrier density pulsation (CDP), carrier heating (CH), and spectral hole burning (SHB) contributions on FWM efficiency are discussed. Effect of QD ground state and wetting layer are included. An additional parameter appears in the gain integral relation of QD SOAs. An equation formulating pulses in the QD SOAs is introduced. We have found that FWM in QD SOAs is detuning and is pulse width dependent. For short pulses, CH is dominant at high detunings (10-100 GHz) while at higher detunings (>100 GHz) the SHB is the dominant one. Undesired paunch behavior is shown in QD SOAs then, CDP must be reduced. © 2014 Elsevier B.V. All rights reserved. | Elsevier | 15671739 | |

To understand how the effect of temperature changes the layers surface, the surface topography was characterized through atomic force microscopy (AFM) and fractal analysis. Pt Schottky contacts grown on nanostructure Al0.08In0.08Ga0.84N thin film grown by molecular beam epitaxy technique on sapphire substrate at annealing temperatures range of 300-500 °C were used. AFM analysis was performed in contact mode, on square areas of 10 × 10 μm2, by using a Nanosurf Easyscan 2 AFM system. Detailed surface characterization of the surface topography was obtained using statistical parameters of 3D surface roughness, according with ISO 25178-2: 2012, provided by the AFM software. The results revealed that the high quality Schottky contact with the Schottky barrier heights and ideality factor of 0.76 and 1.03 respectively can be obtained under 30 min annealing at 400 °C in N2 ambience. The surface roughness of Pt Schottky contacts on quaternary n-Al0.08In 0.08Ga0.84N thin film revealed a fractal structure at nanometer scale. Results obtained by fractal analysis confirm the relationship between the value of the fractal dimension and the statistical surface roughness parameters. AFM and fractal analysis are accurate tools that may assist manufacturers in developing Pt Schottky contacts on quaternary n-Al 0.08In0.08Ga0.84N thin film with optimal surface characteristics and provides different yet complementary information to that offered by traditional surface statistical parameters. © Springer Science+Business Media New York 2013. | | 9574522 | |

Since the pump power is much larger than the other pulses, this makes the differential equation of pump not coupled with the other equations, hence it can be solved alone. In this paper, we consider that the differential equation of pump is linear by assuming that the amplifier is divided into small sections to be the power change through each section is too small. Solving the resulting pump equation requires calculating the integrated gain, where the integrated gain is calculated after each section numerically by an iterative equation that was derived. Simultaneously, the solution of the probe and conjugate equations were also calculated after each section, where a simple recursive formula was found. Finally, the conversion efficiency will be calculated, where the present analysis agrees very well with the numerical solution. © 2013 King Fahd University of Petroleum and Minerals. | Springer Verlag | 2193567X | |

Simulation results indicated that by increasing In composition of the InxGa1-xN waveguide layers, the threshold current decreases, the slope efficiency, and differential quantum efficiency (DQE) increase, whereas the output power decreases. The increase in the In composition of the InGaN waveguide layers increases the refractive index and consequently increases the optical confinement factor (OCF) which result in the increase in the slope efficiency and DQE and the decrease in the threshold current. The decreasing movement of electron and hole carriers from the bulk waveguide layers to the active regions also causes to decrease the output power. A new LD structure with InGaN/GaN superlattice (SL) waveguide layers has been proposed to exploit the increased OCF of InGaN waveguide structures, and the enhanced electron and hole mobilities and the tunneling effect of the periodic structure of the SL structures. The results also showed that the use of InGaN/GaN SL waveguide structures effectively improves the output power, slope efficiency and DQE and decreases the threshold current of the LD compared with (In)GaN bulk waveguide structure. © 2013 Elsevier GmbH. | | 304026 | |

Enteritidis isolates, 28 from poultry houses and 32 from clinical samples, were isolated during 2010. These isolates were subjected to testing and analyzed for antibiotic resistance, virulence genes, plasmids and plasmid replicon types. To assess genetic diversity, pulsed-field gel electrophoresis (PFGE) fingerprinting, using the XbaI restriction enzyme, Multiple-Locus Variable-Number Tandem Repeat Analysis (MLVA) and plasmid profiles were performed. All isolates from poultry, and 10 out of 32 clinical isolates were sensitive to ampicillin, chloramphenicol, gentamicin, kanamycin, nalidixic acid, sulfisoxazole, streptomycin, and tetracycline. Twenty-one of thirty-two clinical isolates were resistant to ampicillin and tetracycline, and one isolate was resistant to nalidixic acid. PFGE typing of sixty ser. Enteritidis isolates by XbaI resulted in 10-12 bands and grouped into six clusters each with similarity from 95% to 81%. The MLVA analysis of sixty isolates gave 18 allele profiles with the majority of isolates displayed in three groups, and two clinical isolates found to be new in the PulseNet national MLVA database. All isolates were positive for 12 or more of the 17 virulence genes mostly found in S.enterica (spvB, spiA, pagC, msgA, invA, sipB, prgH, spaN, orgA, tolC, iroN, sitC, IpfC, sifA, sopB, and pefA) and negative for one gene (cdtB). All isolates carried a typical 58kb plasmid, type Inc/FIIA. Three poultry isolates and one clinical isolate carried small plasmids with 3.8, 6, 7.6 and 11.5kb. Ten of the clinical isolates carried plasmids, with sizes 36 and 38kb, types IncL/M and IncN, and one isolate carried an 81kb plasmid, type IncI. Southern hybridization of a plasmid with an Inc/FIIA gene probe hybridized one large 58kb plasmid in all isolates. Several large and small plasmids from poultry isolates were not typed by our PCR-based method. These results confirmed that PFGE fingerprinting has limited discriminatory power for ser. Enteritidis in both poultry and clinical sources. However, the plasmid and MLVA allele profiles were a useful and important epidemiology tool to discriminate outbreak strains of ser. Enteritidis from poultry and clinical samples. © 2013. | | 7400020 | |

This method improves the convergence of the series solution in the n HAM which was proposed in (see Hassan and El-Tawil 2011, 2012). The proposed method provides an approximate solution by rewriting the n th-order nonlinear differential equation in the form of n first-order differential equations.

The finite volume method was used to solve the corresponding continuity, momentum, and energy equations using the K -ε model. Three cases, corresponding to three different step heights, were investigated for Reynolds numbers ranging from 30,000 to 100,000 and temperatures ranging from 313 to 343 K. The bottom of the wall was heated, whereas the top was insulated. The results show that the Nusselt number increased with the Reynolds number and step height. The maximum Nusselt number was observed for case 3, with a Reynolds number of 100,000 and temperature of 343 K, occurring at the second step. The behavior of the Nusselt number was similar for all cases at a given Reynolds number and temperature. A recirculation zone was observed before and after the first and second steps in the contour maps of the velocity field. In addition, the results indicate that the coefficient pressure increased with increasing Reynolds number and step height. ANSYS FLUENT 14 (CFD) software was employed to run the simulations. © 2013 Hussein Togun et al. | | 1024123X | |

Inspired by the abovementioned structures, a new LD structure with a quaternary AlInGaN MQB EBL has been proposed to improve the performance characteristics of the deep violet InGaN DQW LDs. Simulation results indicated that the LD structure with the quaternary AlInGaN MQB EBL present the highest output power, slope efficiency and differential quantum efficiency (DQE) and lowest threshold current compared with the above mentioned structures. They also indicated that choosing an appropriate aluminum (Al) and indium (In) composition in the quaternary AlInGaN MQB layers could control both piezoelectric and spontaneous polarizations. It will decrease the electron overflow from the active region to p-side and increased the contribution of electron and hole carriers to the radiative recombination effectively. Enhancing radiative recombination in the well using the quaternary AlInGaN MQB EBL also increased the optical output power and optical intensity. © 2013 Elsevier GmbH.

The objective of this study was to determine the effect of gum arabic on the antioxidant activity, physicochemical properties, sensory quality and microbial analysis of papaya fruits. Gum Arabic in aqueous solutions of 5% and 10% was applied as edible coating to green-mature papaya and stored at 13°C±1 for 15 days. The result of the study showed that papaya fruits coated with 10% GA and stored for 7 days had significantly (P<0.05) higher antioxidant capacity (TPC, TFC, FRAP, DPPH and ABTS) and sensory evaluation than the sample control or other treated fruits. In general GA affected significantly (P<0.05) the physicochemical properties (color, pH, TA, moisture and TSS) in papaya fruit at different concentrations with storage days the highest values were recorded in sample control (untreated) and the lowest values in GA10% and GA5%. In addition, the 10% concentration depicted a significant (P<0.05) decrease microbial records when stored with 10% GA. The results suggested that gum Arabic 10% preservative material, could delay the ripening process by inhibiting the respiration rate in the papaya fruit and improves the postharvest quality during cold storage. | | 9744290 | |

This study has covered two types of QD structures: the two-level QD structure, where the ground state (GS) and wetting layer have been considered; and the three-level QD structure, where the excited state (ES) has been taken into account. The relations for differential gain were also discussed. FWM efficiency and its components, comprising spectral hole burning, carrier heating and carrier density pulsation (CDP), are calculated. The results show that inclusion of ES is essential. At a high carrier density and for a long term frequency, the FWM was found to be detuning independently while it is symmetric for short pulses. Neglecting CH makes the FWM in QD SOAs symmetric and detuning independent, which are desired characteristics for optical communication applications. The results corroborate available experimental observations. The effective capture time of QD is the main parameter and can be ascribed to the differences between the two- and three-level models. © 2013 IOP Publishing Ltd. | | 223727 | |

Three different shapes related to the micro-channel depth and width is chosen for examination. Silicon, aluminum, and graphene are used as substrate materials for this study. The overall heat sink consisted of an array of rectangular micro-channels. Three different surface heat fluxes and three different volumetric flow rates are used for three cases. Water with non-temperature-dependent thermal properties is used as a coolant for steady-state, fully developed laminar flow in the micro-channels. From a heat transfer (thermal performance) perspective, it is found that graphene most effectively reduce the thermal resistance.

The effects of interface traps, bulk traps and polarization charges are investigated. It was observed that the role and dynamic of traps affect the device performance which requires a precondition to calculate the DC characteristics that are in agreement with the experimental data. On the other hand, polarization charges lead to quantum confinement of the electrons in the channel and form two-dimensional electron gas. The electron quantization leads to increasing the drain current and shift in the threshold voltage. The device performance can be improved by optimizing the fixed interface charge and thus reducing the bulk traps to enhance the DC characteristics. © 2013 Elsevier Ltd.

Different types of interplanetary (IP) type II bursts have been observed, where the more usual ones show narrow-band and patchy emissions, sometimes with harmonics, and which at intervals may disappear completely from the dynamic spectrum. The more unusual bursts are wide-band and diffuse, show no patches or breaks or harmonic emission, and often have long durations. Type II bursts are thought to be plasma emission, caused by propagating shock waves, but a synchrotron-emitting source has also been proposed as the origin for the wide-band type IIs. Aims. Our aim is to find out where the wide-band IP type II bursts originate and what is their connection to particle acceleration. Methods. We analyzed in detail 25 solar events that produced well-separated, wide-band IP type II bursts in 2001-2011. Their associations to flares, coronal mass ejections (CMEs), and solar energetic particle events (SEPs) were investigated. Results. Of the 25 bursts, 18 were estimated to have heights corresponding to the CME leading fronts, suggesting that they were created by bow shocks ahead of the CMEs. However, seven events were found in which the burst heights were significantly lower and which showed a different type of height-time evolution. Almost all the analyzed wide-band type II bursts were associated with very high-speed CMEs, originating from different parts of the solar hemisphere. In terms of SEP associations, many of the SEP events were weak, had poor connectivity due to the eastern limb source location, or were masked by previous events. Some of the events had precursors in specific energy ranges. These properties and conditions affected the intensity-time profiles and made the injection-time-based associations with the type II bursts difficult to interpret. In several cases where the SEP injection times could be determined, the radio dynamic spectra showed other features (in addition to the wide-band type II bursts) that could be signatures of shock fronts. Conclusions. We conclude that in most cases (in 18 out of 25 events) the wide-band IP type II bursts can be plasma emission, formed at or just above the CME leading edge. The results for the remaining seven events might suggest the possibility of a synchrotron source. These events, however, occurred during periods of high solar activity, and coronal conditions affecting the results of the burst height calculations cannot be ruled out. The observed wide and diffuse emission bands may also indicate specific CME leading edge structures and special shock conditions. © ESO, 2013. | | 46361 | |

The reactor is a set of anaerobic-anoxic-aerobic (A2/O) bioreactors, developed on the basis of an expended granular sludge blanket (EGSB), granular sequencing batch reactor (GSBR) and intermittent cycle extended aeration system (ICEAS). Leachate was subjected to stripping by agitation process and poly ferric sulfate coagulation as a pretreatment process, in order to reduce both ammonia toxicity to microorganisms and the organic contents. The reactor was operated under three different operating systems, consisting of recycling sludge with air (A2/O), recycling sludge without air (low oxygen) and a combination of both (A2/O and low oxygen). The lowest effluent nutrient levels were realised by the combined system of A2/O and low oxygen, which resulted in effluent of chemical oxygen demand (COD), NH3-N and biological oxygen demand (BOD5) concentrations of 98.20, 13.50 and 22.50 mg/L. The optimal operating conditions for the efficient removal of biological nutrient using the ICUSB reactor were examined to evaluate the influence of the parameters on its performance. The results showed that average removal efficiencies of COD and NH3-N of 96.49% and 99.39%, respectively were achieved under the condition of a hydraulic retention time of 12 hr, including 4 hr of pumping air into the reactor, with dissolved oxygen at an rate of 4 mg/L and an upflow velocity 2 m/hr. These combined processes were successfully employed and effectively decreased pollutant loading. © 2013 The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences. | | 10010742 | |

This formula will pave the way to develop all information in regard to SOA devices. Wetting layer (WL), excited state (ES), and ground state (GS) of SOAs have been employed to study the effects of important parameters in such these devices. Good results were obtained, since the effective capture time in QD is controlled. In addition, a suitable effective capture time must give a high integrated gain that required for all-optical applications. For the bulk model, the capture time to GS is not formulated well in previous studies therefore, it underestimates QD model. © 2013 Elsevier B.V. All rights reserved. | | 7496036 | |

Methods: Alkaloids were extracted from ground nutmeg seed kernels with 10% acetic acid in 95% ethyl alcohol. Visceral pain was induced in male and female BALB/c mice by intraperitoneal injection of 0.6% acetic acid. Analgesic effect of alkaloids (0.5 gram or 1 gram per kilogram [g/kg], by mouth) was assessed by evaluating writhing response. Acute toxicity was tested in response to 2, 3, 4, 5, or 6 g/kg of alkaloid extract; the median lethal dose (LD50) was determined by probit analysis. Results: Alkaloid extract at a dose of 1 g/kg significantly reduced the number of writhing responses in female, but not male mice; 0.5 g/kg of alkaloid extract had no effect in either sex. The LD50 was 5.1 g/kg. Signs of abnormal behavior, including hypoactivity, unstable gait, and dizziness were seen in animals given a dose of 4 g/kg or higher; abnormal behavior lasted for several hours after administration of the alkaloids.

These hormones guided many biochemical events resulted in hyperglycemia with a decrease in insulin dependent peripheral glucose utilization. Under these conditions, glucose utilization by non-insulin dependent tissues is increased. One of these tissues is central nervous system, since all nervous tissues except ventral hypothalamus do not require the presence of insulin for glucose utilization and metabolism. Increase of brain glucose level subsequently increase synthesis of gamma amino butyric acid (GABA). Elevation of GABA as a result of hyperglycemia, has inhibitory effect on the secretion of brain catecholamines. Therefore, it was expected that the negative feedback mechanism between central GABA and catecholamine represent a resistant mechanism against stress. © IDOSI Publications, 2013. | | 19920075 | |

The measurements are performed on Ti/Al contacts which have been annealed to various temperatures from 400-700 °C with times of 5, 15 and 35 minutes, where the electrical behaviors of each condition are compared. For relatively different annealing temperatures, substantial differences of the SCR values are observed between different duration samples. The changes in the surface morphology after the annealing treatment were examined using scanning electron microscopy (SEM). The study has resulted in producing contact from the Ti (200 nm)/Al (50 nm) metallization scheme with the lowest specific contact resistivity of ρc= 0.054 ωcm2 after annealing in nitrogen for 10 minutes (cumulated time of 15 minutes) at 400 °C. | | 19855761 | |

In this paper, we extend the idea to present a recovery-based a posterior error estimator for finite volume methods which employ the nonconforming linear trial functions to approximate elliptic interface problems. The method recovers the flux and gradient in H(div) and H(curl) conforming finite element spaces with a weighted L2 projection, respectively. The reliability and efficiency bounds are established. Numerical experiments are given to support the conclusions. © 2013 Published by Elsevier Inc. All rights reserved. | | 963003 | |

However, oxygen vacancies, which are inevitable donor defects mobile under bias at room temperature, lead to undesirable leakage current in SrTiO3 thin films. Epitaxially grown SrTiO3 on lattice mismatched substrates leads to strained SrTiO3, inducing structural phase transitions from a cubosymmetric non-ferroelectric geometry to tetragonal and orthorhombic structures, depending upon the sign of the strain. In this study, density functional calculations have been performed to determine the impact of isotropic biaxial tensile strain in a (001) plane upon the phase of SrTiO3 and the activation energy for the migration of oxygen vacancies in such strained SrTiO3. The phase transition of the host material yields anisotropy in oxygen vacancy diffusion for diffusion within and between planes parallel to the strain. We found a general reduction in the barrier for diffusion within and normal to the plane of tensile strain. The inter-plane diffusion barrier reduces up to 25% at high values of strain. The variation in the barrier corresponding to in-plane diffusion is smaller in comparison to inter-plane diffusion. Finally, we reflect upon how the interplay between lattice strain with native defects plays a crucial role in the conduction mechanism of thin film, strained SrTiO3. © 2013 AIP Publishing LLC. | | 218979 | |

To assess the genetic diversity, pulsed-field gel electrophoresis (PFGE) fingerprinting and plasmid profiles were performed. All of the isolates were sensitive to chloramphenicol, nalidixic acid, and sulfisoxazole, and four isolates showed intermediate resistance to gentamicin or kanamycin. Eleven isolates, including representatives from each of the source types, were resistant to ampicillin. Four isolates from either clinical or environmental sources were resistant to tetracycline, while an additional 20 isolates showed intermediate resistance to this drug. Fourteen isolates, primarily from food sources, showed intermediate resistance to streptomycin. The S. Javiana isolates were screened by PCR for 17 virulence genes (spvB, spiA, pagC, msgA, invA, sipB, prgH, spaN, orgA, tolC, iroN, sitC, IpfC, sifA, sopB, cdtB, and pefA). All isolates were positive for nine to fourteen of these genes, but none were positive for pefA, spvB and lpfC, which are typically present on the Salmonella virulence plasmid. Seven of the virulence genes including cdtB were found in all 50 isolates, suggesting that S. Javiana from food and environmental sources had virulence similar to clinical isolates. Four clinical isolates and two food isolates carried one or more plasmids of approximately 30, 38, and 58. kb, with the 58. kb plasmids belonging to incompatibility group IncFIIA. Two clinical isolates carried IncI1 type mega plasmid (80. kb), and one clinical isolate carried plasmids of 4.5 and 7. kb. The PFGE profiles resulted 34 patterns in five clusters at a 90% similarity threshold. Our results indicate that S. Javiana isolates have a diverse clonal population among the clinical, food and environmental samples and this serotype possesses several virulent genes and plasmids that can contribute to the development of salmonellosis in human. This study provides data that support the potential transmission of S. Javiana virulence factors from food and environmental sources to cause infections in humans. © 2013. | Elsevier B.V. | 1681605 | |

Also, relations for differential gain, gain integral, and nonlinear susceptibility of both pump, probe, and signal pulses were discussed. Gain and differential gain have been calculated for QD structure. FWM efficiency and its components [spectral hole burning (SHB), carrier heating, and carrier density pulsation] are calculated. It is found that inclusion of ES in the formulas and in the calculations is essential since it works as a carrier reservoir for GS. It is found that QD SOA with enough capture time from ES to GS will reduce the SHB component, and so it is suitable for telecommunication applications that require symmetric conversion and independent detuning. © 2013 Optical Society of America. | OSA - The Optical Society | 1559128X | |

The centralization of the Iraqi government leads to weak decision making because the decisions made by the central government are based on general situations. Hence, the Iraqi government should shift from a centralized government to a decentralized government. This paper proposes an e-government Structure based on decentralization instead of centralization. The proposed e-government Structure will provide improved e-services and increase the interaction and electronic information sharing among the central government, citizens, government agencies, and businesses. This study will help the government distribute responsibilities and become adaptable, thus enhancing planning, leadership, communication, and decision making. © 2013 IEEE. | IEEE Computer Society | | |

Nowadays, there is not an accurate mathematical formula that describes the pulse shape in the presence of these effects. In this work, a theoretical study is introduced to derive a generalized formula. This formula is exactly approached to mathematical relations used in their special cases. The presence of second-order PMD (SOPMD) will not affect the orthogonality property between the principal states of polarization.

The processes consist of air stripping coupled with agitation as a modified of ammonia stripping followed by coagulation-flocculation processes. The main aims of these processes are reducing a concentration of NH 3-N and organic matter as well as enhancing the biodegradability of landfill leachate. Ammonia stripped by the airflow rate of 10 L min-1 at pH 11 for 3 h, while the agitation process applied to air stripping effluent for 2 h at the pH of 11.5 in 150 s-1 gradient velocity. NH 3-N was removed at 96 % as removal ratio by the modified ammonia stripping in 5 h stripping time. Ferric sulfate, poly ferric sulfate and aluminum poly chloride was tested as a coagulant material in the coagulation process. Chemical oxygen demand (COD), suspended solids (SS), turbidity as well as the sludge ratios were discovered for each material operated under optimum condition of pH and dosage. The overall removal of NH3-N, COD, biochemical oxygen demand, total organic carbon, and SS obtained by these processes were 96.5, 71.5, 56.5, 48.5, and 96.5 %, respectively, at the corresponding biodegradable ratio was modified from 0.20 to 0.31. © 2013 Springer-Verlag. | Springer Verlag | 1618954X | |

This equation is applicable for any wavelength division multiplexing system in presence of both interband and intraband effects. The equation is solved numerically regarding the primary conditions of the problem considering the amplitudes of the sideband pulses at the entrance of SOA are zero. The gain of low frequency pulses will be higher than the gain of the high frequency pulses, as well as the gain difference between different pulses will be reduced with the increasing of frequency detuning. On the other hand, the effects of saturation and the asymmetric gain will control the mixing efficiency of the sideband pulses generated on the left and right of active pulses depending on the power of the input pulses and the frequency detuning. © 2012 Kadhim et al. | | 18479790 | |

The most widely utilized valve is the solenoid ON/OFF valve because of its simplicity and low cost. However, it has poor controlling performance, which increases the nonlinear behavior occurring in hydraulic systems. This paper devotes on the development and implementation of an adaptive learning algorithm as a real-time controlling algorithm for a hydraulic servosystem utilizing a solenoid valve. The proposed adaptive learning algorithm is a special Artificial Neural Network (ANN) model. ANN is a computer program that provides human brain learning capability to computers for a specific task. In this approach, ANN predicts the controlling action for certain operating parameters learned through a training process. The operating parameters and the result controlling action datasets are collected from experimental operations and then provided to the ANN to learn during the training process. The real-time operating results of the hydraulic servosystem using the adaptive learning algorithm show a compliance of the actuator, which is a linear hydraulic cylinder, to the desired displacements. The controlling through learning concept has the potential to overcome the drawbacks of traditional controllers through the ability to adapt to any changes in the dynamic behavior of a hydraulic servosystem. © 2012 AUT University. | | | |

The impinging jet flow was inclined towards the main cross flow and the angle of inclination is ranged from 30° to 90°. The ribs were in staggered arrangement and aligned after the slot jet in normal direction to the main cross flow. The effect of angle of inclination and contraction ratio on thermal field was studied for jet and channel Reynolds number of 20000 and 16000 respectively. The aim of the present study is to verify how adding staggered ribs with inclined jet flow to the problem of backward facing can enhance the rate of heat transfer. The governing partial differential equations of continuity, Navier-Stockes and energy was discretised on non-uniform staggered grid by using finite volume method. The discretised algebraic equations were solved by using a built home computer program based on simple algorithm. The conducted results show that the considered flow geometry increased noticeably the rate of heat transfer for the studied contraction ratios and angle of inclination. It was observed that the rate of heat transfer is decreased as angle of inclination increases. © (2012) Trans Tech Publications. | | 10226680 | |

Two impellers having different diameters were tested. The aim of the present study is to extend the scientific research of the related studies to high speed centrifugal pump which has a logarithmic profile. The variation of dynamic pressure fluctuations on the front wall of volute casing around the impeller is predicted at different values of volume flow rates. Also the pump performance was tested for the considered values of the volume flow rate. The governing partial differential equations of continuity and momentum were dicretised to algebraic equations by using CFD commercial code(FLUENT 6.3). This code has the ability to transfer the complex physical domain to a computational one by using GAMBIT software. The effect of turbulence was simulated by using a standard k-ε model.

This model takes into account all peculiar characteristics in the quantum dots such as inhomogeneous broadening of the gain spectrum, the presence of the excited states on the quantum dot and the non-confined states due to the presence of wetting layer and the barrier. The contribution of quantum dot groups, which cannot follow by other models, is simulated. The results obtained from this model show the feedback oscillations, the periodic oscillations which evolves to chaos at higher injection current of higher feedback levels.

The problem was investigated for Reynolds numbers up to 32000. The effect of a step height, the number of ribs and the rib thickness on the flow and thermal field were investigated. The computed results are presented as streamlines counters, velocity vectors, and graphs of Nusselt number and turbulent kinetic energy variation. A control volume method employing a staggered grid techniques was imposed to discretize the governing continuity, full Navier-Stockes and energy equations. A computer program using a SIMPLE algorithm was developed to handle the considered problem. The effect of turbu-lence was modeled by using a k-j{cyrillic, ukrainian} model with its wall function formulas. The obtained results show that the strength and size of the recirculation zones behind the step are increased with the increase of contraction ratio (i. e. with the in-crease of a step height). The size of recirculation regions and the reattachment length after the ribs are decreased with increasing of the contraction ratio. Also the results show that the Reynolds number and contraction ratio have a significant effect on the variation of turbulent kinetic energy and Nusselt number. | | 3549836 | |

Hydrodynamic and heat transfer characteristics in a laminar, 3-D, incompressible, slip flow, steady state and counter flow are proposed. The Navier-Stokes equations and energy equation for the hot and cold fluids are solved with the slip velocity and temperature jump conditions. The governing equations are discretized using finite-volume method-upwind differencing scheme, and then these are solved using SIMPLE algorithm method on staggered grid with FORTRAN code. From the obtained results it was found that the factors affecting the effectiveness are: Reynolds number Re, thermal conductivity ratio Kr, Knudsen number Kn and aspect ratio α. Increasing of Re, Kn and α separately lead to decrease the effectiveness. While the effectiveness increases with increasing Kr until it reach a certain optimal value which gives the maximum effectiveness at Kr = 90. Also, it is found that Nusselt number decrease with increases Knudsen number. Increasing of Re and Kn separately lead to increase pressure drop. © 2011 Elsevier Masson SAS.

The impinging jets were inclined towards the upstream cross flow and the angle of inclination was varied from 30 to 90. The effect of an inclination angle, the size of slot jets and the contraction ratio on the flow and thermal field was examined. The governing elliptic Navier-Stockes, energy and turbulence model equations were discretised by using a finite volume method. The k-ε model was used to model the turbulence. A computer program was developed to solve these equations by using the SIMPLE algorithm with a staggered grid technique. The aim of this paper is to show how the inclined impingement cooling inside a channel backward facing can represent a significant factor to enhance the rate of heat transfer and producing complex flow field features. The computed results show that the size and strength of recirculation regions are increased as angle of inclination increases. Such increase is also found with increasing the contraction ratio (SR). However this effect seems to be little compared with angle of inclination. The local rate of heat transfer is enhanced as the angle of inclination increases. The validation of the present scheme is performed through comparison with available published results. © 2011 IEEE. | | | |

The hydrodynamic and thermal characteristics of this suspension flows in microchannels of CFMCHE is numerically investigated. The MEPCM suspension used in this paper consists of microcapsules constructed from n-octadecane as a phase change material (PCM) and the shell material is polymethylmethacrylate, these capsules are suspended in water in a concentration of (0-20)%. From the results, using of MEPCM suspensions as a cooling fluid lead to modify thermal performance of a CFMCHE by increasing its effectiveness but it also lead to increase the pressure drop. From heat transfer (thermal performance) point of view it is better to use this type of fluid to increase cooling efficiency of a CFMCHE, but due to extra increase in pressure drop it leads to reduce the overall performance compared with pure fluids. Therefore its use depends on the application at which this heat exchanger is used. © 2010 Elsevier Ltd. All rights reserved. | | 13594311 | |

The free energy of a mixed spin Ising ferrimagnetic model was calculated from a mean field approximation of the Hamiltonian. By minimizing the free energy, I obtained the equilibrium magnetizations and the compensation temperatures. Clear indications of the single-ion anisotropies on the compensation points of the mixed spin-3/2 and spin-5/2 ferrimagnetic lattices are found. Some interesting behaviors of these systems are obtained depending not only on the values of magnetic anisotropies for both sublattice sites but also on the lattice structure. The longitudinal magnetic fields dependence of the spin compensation temperature is the main focus of research. The possibility of many compensation temperatures is indicated. © 2010 Elsevier B.V.

Fully elliptic Navier-Stockes and energy equations are disrectized using finite volume method along with a staggered grid techniques. The resulting algebraic equations were solved by using semi-implicit line by line Guase elimination scheme. The effect of turbulence was incorporated to treat the regions near the walls. The flow and thermal fields are investigated for different parameters such as the relative baffles height, Rayleigh number and the distance between baffles. The conducted results indicated that the resulting vortices are decreased in number and elongated with the decrease of the dimensionless relative baffle heights. Also the results show that the rate of heat transfer is increased with the increase of Ra especially for the region near the baffles. © 2010 by ASME. | | | |

Single- and double-butt joints were used for microstructural (light and scanning electron microscopy and X-ray diffraction) and mechanical property (double shear test) studies, respectively. The joints produced with CuZr filler alloys (containing 2%, 4%, 6% and 8% Zr, wt%) showed low shear strengths (0.2-0.4 MPa) due to the presence of ZrO2 at the braze-substrate interface and failed in mode I crack opening. Higher shear strengths of 15-24 and 42 MPa were obtained by using CuTi filler alloys (containing 2%, 4%, 6%, 8% and 10% Ti, wt%) (mode II/mode III dependent on the Ti content) and the eutectic (Ag-27 wt% Cu-5 wt% Ti) alloy, respectively. The high shear strengths were attributed to the small amount of Cu 2(AlTi)4O at the braze-substrate interface and led, in the case of the ternary alloy, to the failure of the substrate rather than the braze (mode III axial splitting). © 2010 Elsevier Ltd and Techna Group S.r.l.

Also, the PMD leads to differential group delay (DGD) among the polarization components. The presence of polarization dependent loss (PDL) vector leads to attenuating one of the components and increases the other by a magnitude determined by the value of PDL vector. The study of each phenomenon individually does not give a proper description of the physical nature of the optical fiber system, because these two phenomena arise together at the same time. In this paper, a new theoretical model is introduced to determine the output SOP as a function of PMD, PDL, and input SOP. On the other hand, a new expression was formulated to the dynamical equation and proved that the principal state of polarization (PSP) vector is a complex, where real and imaginary parts of PSP vector represent the PMD and PDL vectors, respectively. Using these vectors, a new value of DGD and PDL may be found. © 2010 Elsevier Ltd. All rights reserved. | | 303992 | |

These levels are: The ground- and excited-states in the QD, the wetting layer (WL) and separate confinement heterostructure (SCH) layers. The most possible relaxation paths and carrier transport are considered in two types of QD structures: GaN/AlxGa1-xN/AlN and InxGa1-xN/ In0.04Ga0.96N/ GaN. Effect of: QD and WL compositions, QD sizes, doped and undoped active regions is studied. The RIN is shown to be reduced with higher Al content in the WL, while an increased is shown for InGaN QD structures. RIN decreases with size reduction. Increased doping until 12 acceptors/QD reduced RIN also.

Ventricular tachycardia is a main presenting feature. There are no known reports of this disease from the Arab countries in the Middle East. This is the first report of 34 patients from Iraq. Methods: Thirty four patients with ARVC/D diagnosed from January 2003 to May 2007 according to the International Task Force criteria were included in this study. Results: All patients presented with ventricular tachycardia of left bundle branch block morphology. The following findings were seen on the 12-lead electrocardiography during sinus rhythm: T wave inversion V1-V3 or beyond in 80%, epsilon wave in 28%, and parietal block in 48%. Right ventricular enlargement by echocardiography was seen in 69%. Twenty two per cent had a family history of sudden cardiac death. All patients were treated with implanted cardioverter-defibrillators. Conclusions: ARVC/D is a disease seen in Iraq. It requires a high diagnostic suspicion with verification using the international task force criteria. © 2010 Via Medica. | Via Medica | 18975593 | |

Their size and shape may have considerable effect on the thermal and hydraulic performance of a heat exchanger. In this paper numerical simulation is carried out to solve 3D developing flow and 3D conjugate heat transfer of a balanced counter flow microchannel heat exchanger (CFMCHE) to evaluate the effect of size and shape of channels on the performance of CFMCHE for the same volume of heat exchanger. The effect of shape of the channels on its performance is studied for different channel cross-sections such as circular, square, rectangular, iso-triangular and trapezoidal. Results show that for the same volume of a heat exchanger, increasing the number of channels lead to increase in both effectiveness and pressure drop. Moreover circular channels give the best overall performance (thermal and hydraulic) among various channel shapes. New correlations are developed to predict the value of heat exchanger effectiveness and performance index as a function of relative size of channels with overall heat exchanger volume, Reynolds number and thermal conductivity ratio. © 2009 Elsevier Masson SAS.

Methods: This study was conducted at Al-Kadhimiya Teaching Hospital, Baghdad, Iraq, from July 2006 to February 2007. Twenty-seven healthy subjects, 44 type 2 diabetics, and 36 LSR patients were studied. The HbA1c level, plain x-ray, and MRI of the lumbosacral region and different electrophysiological tests were assessed. Results: The sural sensory nerve action potential (SNAP) amplitude values were reduced in 56.3%, and the sural/radial amplitude ratio (SRAR) values were reduced in 71.8% in the diabetic patients, but not in the LSR group. The peroneal compound muscle action potential (CMAP) amplitude was low in 70.45% DAN patients versus 35.5% LSR patients. Peroneal F-minimum (Fmin) values were prolonged in 56.8% DAN versus 32.25% LSR patients. The F-persistence (Fp) values were low in 72.7% of DAN, versus 45.2% of LSR patients. However, the F-chronodispersion (Fc) was abnormal in 71% of LSR versus 11.4% of DAN patients. Conclusion: The SRAR was found to be more significant than the sural SNAP amplitude alone in the differential diagnosis of the 2 groups. Abnormal peroneal Fc and Fp seems to be valuable tests in the detection of LSR and DAN patients. | | 13196138 | |

Little is known about ADHD in Al Nassiriya, there Objectives: To determine the prevalence of ADHD and, its subtypes comorbid neurological and -psychiatric disorders and their relationship with sociodemographic variables among first grade primary school pupils in Nassiriya city. Method: Cross sectional study involving 200 first grade primary school pupils of both sexes at Nassiriya city during the period January-March 2006. Each pupil was tested by English version of MINI (International neuro-psychiatric interview ADHD by a psychiatrist. Results: ADHD prevalence rate was 15% (9% males and 6% females). AD was the major subtype (60%), combined type (26%). HD (13%). The majority of ADHD cases were found in groups with low academic achievement (10%), unemployed parents (8%), and living in city center (11%). All these variables were statistically higher in ADHD group. Speech disorder (26%) represented the main comorbid neurological disorder while conduct disorder (23%) constituted the main comorbid psychiatric disorder. Conclusion: In Nassiriya primary school children, ADHD prevalence rate was 15%'. The three subtypes (AD, HD, and Combined) were more prevalent in males than females. These results have to be considered for future healthy public and private programs. | | 18175562 | |

This new model makes it possible to calculate gain from excited states in an easier manner where an inhomogeneous density of states is used with the probability functions taken from their rate equations. Effect of parameters like pumping level, intrinsic relaxation time (τ0) and temperature on the excited-state gain are examined. A comparison between thermal and nonthermal coupling is considered. It is found that longer τ0 is irrelevant for thermal coupling. © 2006 Elsevier B.V. All rights reserved. | | 13869477 | |

The four-level structure-dependent model introduced in this work enable us to study relaxation, recombination and emission processes in the QD region. Carrier recombination outside the dot (inside the quantum-well region), which is impossible to study with other models, is studied here. In this paper, it is shown that noise can be split into five sources. Phonon bottleneck effect is shown to increase the noise. © 2004 Elsevier B.V. All rights reserved. | | 222313 | |
