Social Skills represents an especially important set of competencies in healthcare professionals. This work aimed to evaluate different methodologies available for the training of SS in nursing students. A quasi-experimental investigation was designed in which 189 university students participated divided into a control group and three training groups. The experimental groups were made up of students who took the subject of SS. A behavioral approach was compared with two levels of implementation of the collaborative learning technique known as Aronson\'s puzzle. A pre-test and a post-test were performed using the Interpersonal Difficulties Questionnaire. The results showed greater effectiveness of training through cooperative learning, a superiority that was only verified when the technique was introduced systematically in the classroom, endorsing the relevance of using this methodology in university teaching when it comes to strengthening social interaction skills.
Wheat high-yielding varieties were introduced as a part of the “Green Revolution” to increase agricultural productivity in order to alleviate hunger and poverty in the world. This study, carried out on the most important durum wheat releases in the 20 the century, landraces, old and modern varieties, highlights the impact of world green revolution on wheat breeding in Tunisia. The obtained results spotlighted the changes in yield components and major quality traits and pointed the 1970 as turning year in the Tunisian durum wheat history. Indeed, the breeding after 1970 as much as had significantly enhanced grain yield by increasing number of kernel by spike emphasized gluten strength, it had reduced significantly the thousand kernel weight, protein, wet and dry gluten concentrations. Furthermore, The PCA and clustering analysis showed two distinct groups, where modern varieties was significantly apart from landraces and old varieties and illustrated the impact of dwarfing durum genotypes on Tunisian durum history. This study pinpoints the importance of reintroduction of landraces in future breeding program. for wheat quality improvement. In particular, Jnah-Khottifa, has shown interestingly both high thousand kernel weight and protein concentration which makes it an appealing genotype for traditional food “couscous” end-use.
In this study, cellular polypropylene based composite foams were prepared using an universal injection moulding machine. The chemical foaming agent was added to neat polypropylene (PP) polymer, talc filled polypropylene composite and talc filled polypropylene/ethylene-propylene-diene blend composite materials at the ratio of 1% and 2% by weight. The influence of foaming agent content on the mechanical and cellular properties of both neat PP polymer and PP composites was investigated. The results showed that the tensile strength, tensile modulus, impact strength, hardness, cell diameter, foam density and viscosity values decreased while cell density increased with the increment in chemical blowing agent content.
Hypericum L. genus is widely used in traditional folk medicine around the world. Hypericum heterophyllum, unlike the other species, do not contain hypericin, and pseudohypericin. The biological activity, phenolic and element content of Hypericum heterophyllum’ methanol and acetone extracts was determined in the study. The total antioxidant status of the extracts were determined by commercial kits. Antibacterial effect of extracts was investigated on seven bacterial strains. Cytotoxic effects of the extracts on lung cancer cell lines were determined. Phenolic content was determined by LC-ESI-MS/MS. Elements in the plant were determined by ICP-OES. The total phenolic content and antioxidant status of the species’ methanol extract of were found to be higher than the acetone extract. Both of the extracts at a concentration of 20% have an antibacterial effect, especially the antibacterial effect of acetone extract. It was determined that acetone extract has an anticarcinogenic impact depending on the dose. Chlorogenic acid, miquelianin and isoquercitrin are the most abundant flavonoids in methanol and acetone extract. The plant contains Ca, K, and Mg elements in high concentrations. The phenolic substances and elements in Hypericum heterophyllum, widely used in our country, have been presented for the first time in the literature. Besides, it can be said that the plant has antioxidant, anticarcinogen, and antimicrobial activities due to the crucial flavonoids and elements it contains.
The relevant parameters of a pomace olive oil consecutive solvent extraction method using ethanol, and petroleum ether are investigated from dry and wet pomace samples. Oil extraction from dry samples with petroleum ether showed a high yield (11.72±0.30%) with solvent recovery of 89%, while extraction yield with ethanol is (11.1±0.60%) with solvent recovery of 90%. The oil extraction from wet samples with ethanol is possible technically but the economic feasibility is not proven as the solvent recovery is of 62%. The possibility of hydrolysis of the crude extracted pomace oil in alkaline medium is demonstrated. The starch grafting of the obtained long chain mono-fatty acids was accomplished in the presence of Fenton\'s reagent in a DMF/Water solution. Sonication is used for reaction mixture homogeny and the biopolymer was obtained using domestic microwave heating. After characterizing the obtained grafting polymer, it was employed to prepare a composite material with polyvinyl alcohol.
The purpose of the construction of metal matrix composite materials was to combine the desirable properties of metals and ceramics. Metal matrix composites can be considered as advanced materials that have low weight, high strength, high modulus of elasticity, low coefficient of thermal expansion and suitable abrasion resistance. However, one of the problems with making these composites is the unsuitable wettability of the reinforcing particles in aluminum melt, which creates limitations in the construction of these composites. At first, using the ANFIS-PSO compound, suitable conditions for casting were investigated and then, using the results, the conditions of the composite in terms of dimensions and weight percent of SiC nano particle, the preheating temperature of the mold and powder, the melt stirring time, the rotation velocity of the impeller and the casting temperature for achieving the desirable properties for casting parts, were determined. According to the results, it can be seen that the use of the Gaussian membership function causes the least error in the training time. Also, the comparison of this model with the experimental results shows the efficiency of this model.
The present study aims to understand, clarify and test the impact of credit analysis indicators on the reduction of banking risks, as well as propose best methods, practices and methods of credit analysis using its financial indicators to analyze credit-seeking clients' financial statements to reduce credit risks, thus representing the independent variable of financial indicators in their dimensions: (liquidity indicators, indebtedness indicators, profitability indicators and activity indicators), representing the bank risk variable, and the search community is one of all Iraqi banks whose financial statements span the period of time from (2012 to 2020), where 20 banks were selected on the basis of their importance in the Iraqi banking system and the volume of available data, and the banks' data were used and analyzed using the statistical program (EViews), where the study tool used panel data analysis as a key statistical tool for analyzing the financial data of selected Iraqi banks, this tool has been adopted because it allows for the integration of cross-sectional data with time data, thereby contributing to improved accuracy of the results and increasing the strength of the analysis. A range of statistical methods have been used, including statistical analysis of the financial data through a comprehensive exploratory analysis (Exploratory Data Analysis), as well as diagrams, regression models, sectional self-association and linear association. The study eventually came up with a series of findings, the most important of which are: The existence of a statistically significant correlation between liquidity and capital adequacy in Iraqi banks, where the liquidity variable factor (LTA) in the fixed effects model (0.1264) indicated that an increase in the ratio of liquid assets by one unit increased the ratio of capital adequacy by 0.1264 units, while other factors were consistent.
