Abstract: This study examines the impact of an induced magnetic field on the behaviour of an unsteady viscous Casson magneto hydrodynamic (MHD) fluid flow over a stretching sheet. The Casson fluid flow is influenced by a uniform external magnetic field that is applied perpendicular to the stretching sheet. The problem under investigation is fully defined in terms of certain parameters that characterize the system, namely the Casson parameter , the unsteadiness parameter , the Reynolds number , the magnetic Reynolds number , and the Prandtl number . To simplify the analysis, the governing partial differential equations are transformed into a system of ordinary differential equations using appropriate similarity transformations. The resulting equations are then solved numerically using the collocation method implemented through the MATLAB function bvp4c. This study aims to investigate the effects of the characterizing parameters on the skin friction in the system, Nusselt number, steadiness parameter and free surface temperature are analysed and discussed in detail. Fluid velocity initially decreases with increasing unsteadiness parameter and temperature decreases significantly due to unsteadiness. Increasing the Casson parameter suppresses the velocity field but enhances the temperature. The results show that an increase in magnetic parameter, the velocity boundary layer thickness decreases. The presence of transverse magnetic field sets in the Lorentz force which disturbs the Casson fluid flow hence inducing the retarding on the velocity field. These results indicate the potential technological uses of stretchable materials in liquid-based systems, specifically in applications like paint spray for motor vehicles. Several of our computational findings align with existing data in the literature, although discrepancies arise due to the influence of the induced magnetic field.

Abstract: The study explored the influence of the Sermon on the Mount on computer science undergraduate students’ lifestyle and mental well-being. This became imminent due to the immense pressure faced by these students while striving to achieve academic excellence in today’s complex social dynamics, which sometimes lead to heightened levels of stress, anxiety, and lack of direction with regards to ethical decision-making and personal fulfillment. Guided by these, the researchers posed three questions towards actualizing the aim of the study. The population of the study comprised of all three hundred and eighty-one (381) computer science students of Alvan Ikoku federal university of education Owerri (in the 2023/2024 academic session) from which a sample of one hundred and fifty-five (155) persons was drawn using Nwana’s statistical proposition and cluster random sampling technique. The instrument for data collection themed “Exploring the Influence of the Sermon on the Mount on one’s lifestyle and mental well-being (“EIMSMOLWB”), had two sections A and B with Cronbach Reliability Coefficient 0.80 and 0.90. Questions were structured on a four point Likert rating of very high extent (VHE, 4-points), high extent (HE, 3-points), low extent (LE, 2-points) and very low extent (VLE, 1-poin) while mean and frequency counts were used for the analysis. The findings revealed that the moral values of the Sermon, were lowly integrated into educational practices at the institution (2.3). Further revelation showed that to a high extent, the morals influenced the students lifestyle (2.6) and mental well-being (2.8). Guided by these revelations, the researchers concluded that integrating these timeless teachings into the lives of the students will not only enable them experience greater fulfillment and resilience but also provide them with opportunities for deriving inner peace and contentment in their daily lives and overall well-being.

Abstract: The study examined the productivity and utilization of fuelwood in southern Yobe State, Nigeria. The research explored the factors that contributed to the demand for fuelwood and investigated the sources, current methods of fuelwood harvesting and utilization. Data was collected through surveys and visitations to fuelwood sources, markets, observations, interviews with vendors, local households and businesses. Results showed that there is a high demand for fuelwood in the region due to limited access to alternative energy sources such as gas, kerosene and electricity and reliance on traditional cooking methods. Moreover, the unsustainable harvesting practices are leading to loss of biodiversity, soil erosion, deforestation, desertification and environmental degradation. Other effects are extinction of organisms, local climate change and facilitate the release of high amount of carbondioxide into the environment as well as the greenhouse gases, attributing to about 10% of the causes of global warming. The findings suggest the need for implementing sustainable management strategies to meet the growing demand for fuelwood while also preserving the ecosystem. This study provides valuable insights for policy makers and stakeholders to develop effective and sustainable solutions for fuelwood utilization in southern Yobe State, Nigeria.

Keywords: Productivity, utilization, fuelwood, harvesting, forest, energy.

Abstract: This paper explores hot Jupiter core formation much nearer to the star than the traditional in-situ model suggests. We propose that the protoplanetary disk and the hot Jupiter core form concurrently during a star's infancy, when cooler temperatures favor agglomeration near the inner disk. Building on the in-situ model's core principles, our model estimates inner disk formation at a radial distance of about 1.5 times the stellar radius. Within this dense inner region, the Headwind Effect and the cooler temperatures play a crucial role in the formation of the hot Jupiter core. By utilizing the data available on the NASA Exoplanet Archive^[1], we conducted a numerical analysis on six hot Jupiter systems with sufficient data and our findings provide compelling evidence in favor of our hypothesis that — core formation likely occurred within the inner disk region during the early stages of stellar evolution.

Keywords: hot Jupiter formation, early stellar development, protoplanetary disk, headwind effect, density enhancement, core assembly.
