Abstract
This study focuses on utilizing abundantly available seashell ash by dispersing it in AA6063 alloy to form composites. A new aluminium metal matrix composite was developed by reinforcing AA 6063 alloy with particles of seashell ash as reinforcement materials in varying percentages (0, 10, 20, 30, 40 wt.%). The samples were prepared by using the stir casting method. The microstructural characterizations were carried out using optical microscopy and the scanning electron microscope (SEM), revealing particle shape and size descriptions for the composite microstructural features. The results indicate that the composite materials exhibit relatively larger and more uniformly distributed grain sizes compared to the base material. The outcomes demonstrate a significant improvement in the tensile strength and hardness of the composites, accompanied by a decrease in corrosion rates. The best samples display a 90.95% increase in tensile strength, a 38.01% increase in hardness and a 71.5% decrease in corrosion rate in an HCl environment, along with a 46.7% decrease in a NaCl environment. Furthermore, there is a 207.7% increase in impact strength in the sample reinforced with 20 wt.% of seashell ash. Overall, the AA-SS composite with 20% wt. seashell ash exhibits the most favourable properties, featuring a 90.95% increase in tensile strength, a 38.01% increase in hardness and a lower corrosion rate when compared to the control sample.
Gender Discrimination and Performance of Female Employees in Selected Private Universities in Ado/Odo Ota Local Government area, Ogun state, Nigeria
(Bells University of Technology, 2024-08-06) ONWUEGBUNA, Godness Nneoma; Dr onifade, T.A.
This study examined the impact of gender discrimination on performance of female employees in selected private universities in Ado/Odo Ota local government area of Ogun state. Specifically, the study examined the influence of discrimination in managerial roles on the performance (task performance) of female employees in selected private Universities. To achieve the stated research objectives, a quantitative survey research design was adopted as a research objective, a quantitative survey research design was adopted as a research design, and a 25-item structured questionnaire was used as the research instrument for data collcetion. The target population comprised of 404 female employees of selected private universities in Ado/Odo Ota local government area. The sample size of 200 females was determined using taro Yamane formula. The collected data were analyzed with descriptive statistics (Mean and Grand mean) and inferential statistics (Simple Linear Regression).
Effect of Risk Audit As A Project Risk Management Technique On Quality Performance of Building Construction Project In Nigeria
(Bells University of Technology, 2024-02-12) ASADE, Lukman Adekunle; Dr. A.O. Adeodu
The study the application and implementation of project management practices in achieving and enhancing product quality with the investigating of Nestle Nigeria Plc, based on the specific objectives of identity product defect inherent, quality. defects on production quality and quality assurance tools impact on product quality. Survey research design involving qualitative and quantitative data collected through stratified and simple random sampling techniques was used 287 and 332 questionnaires from internal stakeholders and customers were used, coupled with 37 and 18 from suppliers/vendors and regulatory authorities.The differences in project management techniques was determined by Chi-Squares, logistics regression analysis was used to analyse the possible effect of project management practices on size and complexity of products and multiple regressions was used to establish the effect of project management practices on product quality.
Evaluation of Bioactive Compounds and Characterization of Bryophyllum Pinnatum Infusion In Broken Brown Rice-Babbara Nut Extruded Flakes
(Bells University of Technology, 2024-02-12) ABODUNRIN Josephine Olabisi; Prof M.O. Jimoh
Extruded flakes are consumed majorly as breakfast cereals, and this plays a significant role in daily nutritional intake. Extrusion employs technique such as mixing, heating, moisturizing, forming, texturing and cooking to innovate novel food items.The development of functional foods goes beyond mere nutrition, aiming to prevent diseases and promote health.Consumers' growing understanding of the relationship between diet and well-being has driven changes in dietary patterns. Bio active compounds are the atructural books of functional foods providing their medicinal properties and health benefits.
