The asymptotic iteration method for the angular spheroidal eigenvalues with arbitrary complex size parameter c

The asymptotic iteration method is applied, to calculate the angular spheroidal eigenvalues $\lambda^{m}_{\ell}(c)$ with arbitrary complex size parameter $c$. It is shown that, the obtained numerical results of $\lambda^{m}_{\ell}(c)$ are all in excellent agreement with the available published data over the full range of parameter values $\ell$, $m$, and $c$. Some representative values of $\lambda^{m}_{\ell}(c)$ for large real $c$ are also given.Comment: 15 pages, 1 figur

Job satisfaction among private boy school teachers in Riyadh city of Saudi Arabia.

Schools, like other organizations, are established to achieve objectives in societies through their members (teachers). Many elements are important to the achievement of educational goals, but the most important elements are teachers' involvement in affecting change in students. The role performance of teachers has an important effect on the country's development. Their job satisfaction affects their role performance. Job satisfaction of teachers in Saudi Arabia warrants serious consideration. Results emerging from this study will help the Ministry of Education of Saudi Arabia and other administrative agencies improve the situation of teachers and minimize the factors that negatively affecting their job satisfaction. Because of these reasons such a study is needed to determine factors that affect teacher's job satisfaction. We hope that this study will help people administering of the educational system gain understanding of the situation of private school teachers in Saudi Arabia. This study determined that self-confidence, teacher-student·relationships, teacher-teacher relationships, and school climate were positively related to job satisfaction; age, marital status, teaching experience, salary, and self-actualization were not

Coverage of Food Security and Environmental Sustainability Issues in Saudi Arabias Electronic Press

This study aimed to investigate the importance of food security and environmental sustainability in achieving the goals of Vision 2023 in Saudi Arabia. Data was collected using a survey approach with a questionnaire administered to 200 male and female students at different educational stages in the Faculty of Education at King Faisal University. Results showed that 82.5% of the total sample read Saudi electronic newspapers for at least one hour a day, with 14% reading for 1-3 hours, and 3.5% reading for three or more hours per day

Crop management to enhance plant resilience to abiotic stress using nanotechnology: towards more efficient and sustainable agriculture

Nanotechnology has become a transformative tool in modern agriculture, playing a pivotal role in enhancing crop resilience to abiotic stresses, including drought, salinity, and extreme temperatures. As global population growth and environmental challenges place increasing pressure on agricultural systems, nanotechnology plays a crucial role in enhancing crop yields and ensuring long-term sustainability. Nanotechnology, through advanced applications, optimizes nutrient delivery, strengthens plant defense mechanisms, and enables precise monitoring of environmental conditions. These innovations enhance soil quality, regulate physiological responses in plants, and mitigate the adverse effects of environmental stressors, thereby promoting sustainable farming practices and improving food production efficiency. Nanoparticles (NPs), synthesized through green methods using plant or microbial extracts, have shown promise in enhancing stress tolerance by facilitating uptake, translocation, and intracellular movement within plants. Major factors influencing NPs efficacy include size, concentration, composition, and duration of exposure. Biosensors and nanobiosensors provide prognostic tools for real-time detection and management of plant stress. Despite their potential benefits, the use of nanotechnology in agriculture raises concerns regarding environmental and health impacts. The accumulation of NPs in soil and aquatic ecosystems may affect microbial diversity, disrupt soil enzymatic activity, and alter plant–microbe interactions, posing risks to non-target organisms and overall ecosystem health. Moreover, variability in plant responses to NPs complicates the development of standardized application protocols. Therefore, its successful adoption relies on sustained interdisciplinary research, ethical oversight, and the development of sound policy frameworks. This integrated approach is crucial for developing resilient, efficient, and sustainable agricultural systems that can meet future challenges

Exact solutions for vibrational levels of the Morse potential via the asymptotic iteration method

Exact solutions for vibrational levels of diatomic molecules via the Morse potential are obtained by means of the asymptotic iteration method. It is shown that, the numerical results for the energy eigenvalues of $^{7}Li_{2}$ are all in excellent agreement with the ones obtained before. Without any loss of generality, other states and molecules could be treated in a similar way

Enhancing phytochemical content and bioactive aspects in somatic embryogenesis developed from callus of Phoenix dactylifera L.

This research aims to investigate the chemical profile of methanolic (MeOH) extracts of callus and somatic embryogenesis (SE) induced from date palm ‘Barhi’ cv. (Phoenix dactylifera L.) by total polyphenols estimation and gas chromatography-mass spectrometry (GC-MS) analysis. In addition, some biological aspects as antiradical and anti-enzymes inhibitory effects were evaluated by in vitro examinations. Results demonstrated that, total phenol content (TPC) and total tannin content (TTC) were significantly increased by 14.95% and by 16.83%, respectively, in callus than that estimated in SE. Whereas total flavonoid content (TFC) in SE recorded a very high increase rate of 564.4% above that found in callus. GC-MS chromatogram of SE extract had more phytochemicals about 35 molecules were identified, including five specific bioactive compounds with considered ratios ranging between 2.265% and 12.76%. Overall, the determined biological aspects were significantly improved (p < 0.05) in SE, particularly anti-Diphenyl-2-picryl-hydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), and Total Antioxidant Capacity (TAC) by 48%, 92.31%, and 54.35% sequentially as antiradical/antioxidant potentials in terms of IC50 values. Furthermore, anti-α-amylase and anti-α-glucosidase effects were enhanced by 2,750% and 224.16%, respectively, in SE compared to callus results. In summary, MeOH extract of SE was richer in phytochemicals with greater bioactive properties than callus; this evaluated superiority could be attributed to the developmental and morphological differentiation occurring for SE tissues, which may be a prerequisite for greater content production and accumulation of many types of bioactive secondary metabolites. Further prospective pharmacological studies are required to recommend SE of ‘Barhi’ cv. as a natural nutritional and therapeutic source
