To achieve our goal, a study was conducted on the first year students of the Faculty of Science Dhar El Mehraz. Then a questionnaire was made and administered to professors and first year students. The obtained results revealed that the students' reluctance is mainly due to pedagogical difficulties

Evaluate the Socio-Economic Impact of the International Coastal Road (ICR) on Burg Elburullus City

Communities are grappling with environmental, social, and economic challenges due to rapid urbanization and physical changes, with coastal slums bearing the brunt of the impact. Unplanned urban development worsens pollution, inequality, and disaster risk for low-income households. Specific sustainable development plans are vital for tailored solutions based on each community's distinct needs and views. This study examines the socio-economic impacts of the establishment of the International Coastal Road (ICR) in the city of BURJ AL-BURULLUS in Northern Egypt, which marked the beginning of major urbanization efforts in the region in 2002. The physical landscape of the city has undergone significant changes due to urban expansion, with the extension of the city having grown to almost twice the size of the original city. The expansion of the city due to the ICR has caused significant changes to the area's environment, communities, and economies. In particular, the separation of the city from the nearby lake, which was its primary source of income, has had diverse impacts on various aspects of people's lives. This study employed a narrative method to assess ICR's impacts on the area's environments, communities, and economies. Nine villagers with diverse incomes were selected and encouraged to freely share their detailed views. The study focused on the socioeconomic impacts of the changes on the city, but it had significant impacts on all economic, social, and environmental levels. Community participation enhances research outcomes regarding the challenges experienced by impoverished communities due to urbanization. It also assists in the creation of improvement strategies responsive to the distinct requirements of each community by incorporating important perspectives and first-hand experiences of those affected by urbanization

The Preoperative Use of Levosimendan in Patients undergoing Coronary Artery Bypass Surgery with Low Ejection Fraction

Background: Levosimendan is a calcium sensitizer with positive inotropic, vasodilatory, and cardioprotective actions. Levosimendan infusion time may affect the outcomes. Our objective was to evaluate its efficacy and safety when used before coronary artery bypass grafting (CABG) in patients with low ejection fraction. Methods: This prospective observational study included 150 CABG patients with ejection fraction ≤ 40% divided into two groups. In the Levosimendan group (n= 75), it was given preoperatively, and in the conventional group (n= 75), myocardial support was used if indicated. Results: Operative time (344±28.7 vs. 421.4±34.5 min) and cardiopulmonary bypass time (97±17.4 vs. 127.4±24.5) were significantly shorter in the Levosimendan group (P˂ 0.001, for both). Failure to wean from bypass (13 (17.3%) vs. 23 (30.7%), P=0.06) and the need for intra-aortic balloon pump (6 (8%) vs. 14 (18.7%), P= 0.06) were non significantly lower in the Levosimendan group. The mechanical ventilation duration (12±3.3 vs. 19.6±4.7 h, P= 0.04) and ICU stay (3.8±1.2 vs. 5.3±1.4 days, P ˂ 0.001) were lower with levosimendan. Mortality was non-significantly lower in the Levosimendan group (10 (13.3%) vs. 18 (24%), P= 0.09). There were no differences in atrial and ventricular arrhythmias between groups. Conclusion: The preoperative use of levosimendan could improve the outcomes in patients undergoing CABG with low ejection fraction. Levosimendan complication profile was comparable to the conventional approac

Thinking through Errance: Journeying and Waiting among African Travelers in Quito and Dakar

RESUMEN: A partir del cambio de milenio, Ecuador se ha convertido en un lugar de paso, pero también de residencia para migrantes de diferentes países del mundo. Mientras que la fuerza de atracción de este país proviene de requisitos migratorios flexibles como resultado de una política de ciudadanía universal, las condiciones económicas no estimulan la posibilidad de quedarse. Este artículo tiene como punto de partida una reflexión previa sobre el concepto errancia que surgió de un acercamiento a las historias de africanos que esperaban en Dakar (Senegal) para continuar el viaje fuera de su continente. Contrastamos esta experiencia con la de otros africanos que han atravesado el Atlántico y han llegado a Quito. Dos opciones se presentan a estos últimos: continuar el viaje hacia Estados Unidos o quedarse. En ambos casos, las políticas migratorias, el valor de los papeles (pasaportes y visas) y las formas de socialidad influyen en su experiencia como viajeros. En el caso de quienes continúan el viaje hacia Estados Unidos,los riesgos de la travesía se convierten en pruebas de aptitud para recibir asilo.ABSTRACT: Since the beginning of the 21st century, Ecuador has been a point of transit but also of residence for migrants from around the world. While the attraction of this country resides in the flexible regulations of migration which stem from its policy of universal citizenship, the economic conditions there do not encourage migrants to stay. The starting point of this article is a previous study of the concept of errance which emerged from listening to the stories of Africans who were waiting in Dakar, Senegal, as they sought a way to leave from the continent from Africa. The article contrasts their experiences with those of other Africans who manage to cross the Atlantic and land in Quito. There are two options available for them: to either continue the journey toward the United States or remain in Ecuador. In both cases, migration policies, immigration papers and socialities are factors which shape their experience as travelers. For those who continue on their journey to the United States, the risks they run become a proof of their worthiness to be granted asylum

Bank Employee Perceptions of Corporate Social Responsibility Practices: Evidence from Egypt

This study examined bank employee perceptions regarding corporate social responsibility (CSR) practices in Egypt as a developing country. In particular, it explored bank employee perceptions towards the CSR aspects on which banks should focus. It also investigated whether factors such as bank type (i.e., public or private), employee age, experience, job position, and number of CSR training programs undertaken can affect this perception. Data were gathered through a questionnaire distributed to both public and private bank employees. The final sample consisted of 127 employees. SPSS was used to analyse the data. We found that bank employees placed different importance on the CSR aspects on which banks should focus. In particular, they prioritized employment and workplace-related aspects such as operational efficiency, financial literacy, equal employment opportunities, and workplace safety. In contrast, they placed less emphasis on environment-related aspects such as greenhouse gas emission and energy consumption. We also found that bank type, age, employee experience, job position, and number of CSR training programs undertaken could affect the perceptions of bank employees regarding the CSR aspects on which banks should focus. While there is a growing stream of research on CSR, prior research lacks CSR practices in developing markets, especially in the banking sector. To the best of our knowledge, this is the first study to look at the importance and priorities of CSR aspects in Egypt—one of the fastest-growing economies in the developing world. Based on the findings of this study, policymakers and regulators in Egypt such as the Central Bank of Egypt and the Egyptian Banking Institute are advised to request banks to pay more attention to environmental-related aspects of CSR to keep pace with Egypt 2030 vision and develop an action plan that helps increase bank employee awareness regarding the importance of CSR practices and engage employees further in developing their banks’ sustainability strategy

Semi-Analytical Solution Based on Strip Method for Buckling and Vibration of Isotropic Plate

The present paper achieves a semianalytical solution for the buckling and vibration of isotropic rectangular plates. Two opposite edges of plate are simply supported and others are either free, simply supported, or clamped restrained against rotation. The general Levy type solution and strip technique are employed with transition matrix method to develop a semianalytical approach for analyzing the buckling and vibration of rectangular plates. The present analytical approach depends on reducing the strips number of the decomposed domain of plate without escaping the results accuracy. For this target, the transition matrix is expressed analytically as a series with sufficient truncation numbers. The effect of the uni-axial and bi-axial in-plane forces on the natural frequency parameters and mode shapes of restrained plate is studied. The critical buckling of rectangular plate under compressive in-plane forces is also examined. Analytical results of buckling loads and vibration frequencies are obtained for various types of boundary conditions. The influences of the aspect ratios, buckling forces, and coefficients of restraint on the buckling and vibration behavior of rectangular plates are investigated. The presented analytical results may serve as benchmark solutions for such plates. The convergence and efficiency of the present technique are demonstrated by several numerical examples compared with those available in the published literature. The results show fast convergence and stability in good agreement with compressions
