Performance Analysis of Kesterite Solar Cells Under Varying Radiation and Ambient Temperature Conditions
No full textThe demand for efficient and reliable solar energy conversion technologies has driven extensive research on novel photovoltaic materials, including kesterite solar cells. However, their performance is inherently affected by external environmental factors, such as solar radiation and ambient temperature. This research paper presents a comprehensive performance analysis of kesterite solar cells under varying radiation and ambient temperature conditions. SCAPS-1D is employed to model the electrical behavior of kesterite solar cells under different levels of solar radiation. The simulation results demonstrate a direct correlation between incident light intensity and key performance metrics, such as short-circuit current, open-circuit voltage, and fill factor. The influence of spectral variations in solar radiation on the device response is also studied, offering insights into the spectral sensitivity of kesterite solar cells. Furthermore, the impact of varying ambient temperature on the performance of kesterite solar cells is investigated using SCAPS-1D. The simulation analysis reveals temperature-dependent changes in the electrical characteristics of the solar cells. The insights gained from this study provide valuable guidance for the design and optimization of kesterite solar cells, supporting their integration into the renewable energy landscape as a viable and sustainable photovoltaic technology

Information Technology Factor Affecting Firm Performance through Supply Chain Agility
No full textThe purpose of this study is to investigate the elements that influence organisational performance, specifically the aspects pertaining to informational technology and the agility of supply chain management. The flexibility of the supply chain management acts as a mediator in this particular study. Both qualitative and quantitative data were collected for the study. The pharmaceutical businesses in Indonesia were given a questionnaire that they filled out on their own in order to contribute their responses to the current study. A straightforward method of random sampling is utilised in the distribution of three hundred questionnaires across the pharmaceutical industry. The data analysis was done with the help of the smart PLS. The findings of the study indicate that all of the hypotheses can be accepted because they exhibit positive and meaningful outcomes, as opposed to two hypotheses that show results that are negligible. The conclusion of the study includes a discussion of more debate as well as the limitations of the study

Интегральное Образование И Его Обучение На Уроках Математики В Начальных Классах
No full textЯ решила подумать о применении интегрированного обучения в изучении математики в начальных классах и насколько оно эффективно, методика применения. Математика основа познания мира, окружающих событий и это важно в выявлении конкретных закономерностей явлений и в развитии производства, науки и техники и технологий. Именно поэтому эффективна организация предмета математики в интегрированной методике урока в младших классах
Exploring the Benefits and Future of Artificial Intelligence
No full textArtificial Intelligence (AI) is an increasingly popular field that seeks to create machines that can perform tasks that would normally require human intelligence. AI systems are known for their ability to learn and make decisions using data and other inputs, and their capabilities have expanded rapidly in recent years. Some of the capabilities of AI include computer vision, natural language processing, predictive modeling, and decision-making. These capabilities have led to the development of applications such as self-driving cars, virtual assistants, and fraud detection systems. However, the rapid advancement of AI has also raised ethical and social concerns, including issues around job displacement, privacy, and bias. This paper provides an overview of the capabilities of AI and highlights the need for responsible and ethical development and implementation of this technology
Effect of Educational Intervention on Occupational-Stress Management Among Security Personnel in Ogun State, Nigeria
No full textBackground: Occupational stress is a problem of the 21st century and is widespread. It is a harmful physical and emotional response that occur when the requirements of the job do not match the capabilities, resources, or needs of the worker. Therefore, this research examined the influence of an educational intervention on willingness to adhere to occupational-stress reduction practices among security staff of selected private universities in Ogun State, Nigeria.
Methods: A quasi-experimental design was employed for this study. The population consisted of 500 security staff which were purposively selected from two private universities in Ogun State. Normal Distribution Power formula was used to arrive at a sample size of 20 security staff for each university. A convenient sampling technique was used in selecting the participants from the two universities grouped into intervention group (IG) and the control group (CG). A validated questionnaire with Cronbach’s alpha coefficients ranging from 0.77 to 0.96 was used to collect data. IG received educational session’s two-hours weekly for two weeks, and the control group received forty-five minutes, once-weekly for six weeks. Data were collected at baseline and immediate post-intervention. Data were analyzed using descriptive and inferential statistics at 0.05 level of significance.
Results: Results showed that at baseline the attitudinal disposition to occupational-stress reduction practices was low (9.25 ± 2.84) in both the IG and CG. Between the baseline and immediate post-intervention, there was a significant increase (p < 0.05) in the mean score of attitudinal disposition to occupational-stress reduction practices from (from 9.25 ± 2.84 to 12.75 ± 3.21) with a mean difference of 3.50 in IG. However, there was no significant difference (p > 0.05) in the mean score of attitudinal disposition to occupational-stress reduction practices (9.25 ± 3.08 to 10.95 ± 3.93) among CG.
Conclusion: From this study, the educational intervention was effective in influencing the security staff. It is recommended that security agencies of private universities take measures in organizing educational courses to teach stress reduction techniques for better health and well-being of the security staff
