Item Epistemology, culture and physics education: Implication for sustainable development(Department of Science Education, University of Ilorin, Ilorin., 2018-07) Badmus, Olalekan T.; Mustapha, S. I.; Omosewo, E. O.The knowledge and belief of a people form significant component of their culture. The culture is embedded in the ways they think, perceive and behave even in learning situations. How learning takes place have been established in the literature to depend significantly on attitude. Learners attitude towards learning encompasses the language, mode and competence in the delivery of instruction. Aboriginal language and culture influence learning and allow learners to embrace instructions with peculiarity to their lineage. This study examines the confluence of belief, culture, and learning of physics within and outside the classroom. Inferences drawn based on the findings of various researchers regarding all reflected components in this study. Specifically, this study investigated the extent to which all the aforementioned variable influence students learning of physics, taking into consideration the role of physics education in the attainment of Sustainable Development Goals (SDGs) of the United Nations.Item OPTIMIZATION OF NICKEL (II) AND CHROMIUM (III) REMOVAL FROM CONTAMINATED WATER USING SORGHUM BICOLOR(Nigerian Journal of Technology (NIJOTECH), 2017-07-01) Adewoye, L. T.; Mustapha, S. I.; Adeniyi, A. G.; Tijani, J. O.; Amoloye, M. A.; Ayinde, L. J.A central composite design (CCD) under the response surface methodology (RSM)was used to study the effect of three adsorption variables (pH, initial concentration, and adsorbent dosage) in order to determine the optimum process conditions for the adsorptions of Ni (II) and Cr (III) onto sulphuric acid modified sorghum bicolor activated carbon (SBAC).This study yielded removal efficiency of 98.89 % for Ni (II) and 94.27 % for Cr (III) ion under optimal conditions of pH (8), initial metal ion concentration (25 mg/L), adsorbent dosage (10 mg) and pH (7), initial metal ion concentration (5 mg/L), dosage (15 mg);respectively. Statistical analysis of variance results showed a good correlation existed between the experimental and predicted data with R2 values of 0.99 for Ni and 0.98 for Cr. The equilibrium data for Ni (II) adsorption was best described using Freundlich model while Langmuir model best fit Cr (III) adsorption. The mechanism of adsorption for both Ni and Cr adsorptions on SBAC followed Pseudo second order kinetic model.
