In this study, the solutions of the Schrodinger equation (SE) with modified Hylleraas potential in arbitrary dimensions was obtained using the asymptotic iteration method (AIM) to obtain the energy and wave functions, respectively. The energy equation was used to obtain the thermal properties of this system. The effect of the potential parameters and dimensions on the energy spectra and thermal properties was scrutinized thoroughly. It was found that the aforementioned affects the thermal properties and energy spectra, respectively. In addition, we also computed the numerical energy spectra of the MHP for the first time and discussed it in detail. The results of our study can be applied to molecular physics, chemical physics, etc.
A good number of scientist, engineers, laboratory or workshop users have lost their lives and the lives of others due to accidents in the workshop caused by ignorance, neglect or carelessness. This paper focus on the incident and prevalence rate of workshop and laboratory accidents in twenty (20) schools within Cross River State, Nigeria. The investigation took place between January 2008 and December 2012 (a period of five years). A total of 66 departments were investigated. The data was source with the help of the technologist and head of Department of each of the schools. Based on these data, using descriptive analysis, multiple bar chart and Trend analysis (Analysis of variance-SPSS) to show the growth and decline of laboratory or workshop accidents across various departments over the years of study. The result revealed that the average number of accidents occurred most in chemistry department; UNICAL and CRUTECH at 25 and 18 respectively, (table 1 and 2). And that of 18 secondary schools indicated that Bekwara Local Government Area was the highest numbers of accidents (20.0) table 3, while Biase Local Government Area had the least (10.2), physics and biology had recorded less accidents (table 3). In the two universities, computer/Maths statistic Department had less laboratory accident due to not being exposed to heavy chemical. Hence, from this result, 40 workshop safety and precautionary steps are release to avoid or minimize accidents in the laboratory or workshop towards a healthy carrier.
This paper presents the environmental effects of gas flaring on pH values of the soil and rain water in some areas in Niger Delta. Different soil samples and rain water at various proximities from the gas flaring locations were taken. The samples collected were evaluated to determine the pH values of rain-water and that of the soil in the area under investigation. The result obtained shows a remarkable trend as the values of the pH of the soil and that of the rain water increased as we moved away from the gas flaring stations. The pH actually changed from extreme acidic (3.5-4.4) to moderate alkaline (7.9-8.4) as we moved away from the flaring points. The pH values tend to normalize at distances of more than 2 km away from most of the gas flaring points. The low pH values imply that there is formation of acid rain which has dangerous consequences on the environment and on the plants and animals. The resultant health implications of extreme acidity in the rain water and consequently in the soil was also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
