ABSTRACT

Mathematics teaches patience, discipline, and step-by-step problem-solving skills. For those with a substantial background in mathematics, an unlimited number of career opportunities are available. In spite of the tremendous possibility of mathematics or mathematicians many people especially young people do not like mathematics as a subject. In this research, questionnaires were administered to respondents’ i.e. students of Edo State Institute of Technology and Management to actually investigate the influence of mathematics on students choice of their present course of study. The study shows that mathematics plays a very important part in the students’ decision concerning the choice of their present course of study at the school (ESITM).

                                                ABSTRACT

This study examined the principals’ supervisory roles and their impact on students’ academic performance in senior secondary schools in North Central Geo-Political Zone, Nigeria. Seven (7) research questions and four (4) hypotheses were formulated and tested for the study. Related literatures as well as empirical studies were also reviewed. The ex-post facto design was adopted for the study. The Population of the study was 27,221 and 5,496 Teachers, Students and Principals’ representing 20.2% of the total Population were sampled from 216 Senior Secondary Schools using tetrachoric random sampling. A 8-item instrument was developed for data collection titled ‘’Principals’ Students’ Performance Questionnaire (PSPQ). The instrument used for the study was a modified four point-Likert type questionnaire of Strongly Agreed (SA), Agree (A), Disagree (D) and Strongly Disagree (SD). Descriptive statistics of mean and standard deviations were used to answer the seven research questions, while chi-square (X2) test of goodness of fit was used to test the three hypotheses at 0.05 level of significance was used to test hypothesis. The findings revealed that Principals’ supervisory roles performance on students’ academic performance was above average (2.58) in senior secondary Schools in North Central Geo-Political Zone, Nigeria. Based on the findings of the study, it was recommended that principals’ should see supervisory roles performance as daily affairs on students’ academic performance in senior secondary schools.

ABSTRACT

This paper x-rayed poverty reduction and national development through technical vocational education and training (TVET) in Nigeria. It reviewed the present status of TVET, government effort to revamp and revitalize TVET. The study further addressed poverty, classes of poverty, kinds of poverty reduction and its consequences to national development. The study recommended that, in other to combat the negative impact of poverty in Nigeria that funds should be provided for TVET institutions for effective implementation of the program, government should involve organizations and industries in the formulation of the curriculum and in the certification of skills offered; and the World Bank intervention programs in technical vocational education and training in some states of the federation should be extended to other states not presently included to ensure availability of skilled men and women in every part of the country for national development.

Abstract

Health risk index of these heavy metals Cd, Cr, Fe, Zn and Pb have been determined on two vegetables sample (Amaranthuscaudatus and Hibiscus cannabinus), around Gombe road in Bauchi metropolis. The level of the heavy metals in the soil where the vegetables grown were determined. Analysis of the soil and the vegetables samples revealed that, the mean conc. Of the Cd, Cr, Fe, Zn and Pb in Amaranthuscaudatus were, 0.00, 19.4, 275, 12.5 and 0.00 mg/kg, in Hibiscus cannabinus were 0.5, 8.5, 275, 1.5 and 0.00 mg/kg and in the soil were 1.0, 144, 2000, 38 and 14.5mg/kg respectively. All the values obtained were below the permissible limit recommended by WHO/FAO. Only Cd in Hibiscus cannabinus exceeded the maximum permissible limit and it has to be monitored in order to prevent Cd disease outbreak.

Abstract

Concerns for energy required for the running of homes, industries and the economy generally has been of global concern for some decades. Domestic household energy has influence on environmental conservation and sustainable development. This paper reviews the domestic energy consumption in urban/rural settlements of Nigeria. Our study takes an explicitly longitudinal and multilevel approach to understanding this fundamental energy use transition. For this study, a narrative approach was employed. Selected studies were compared and summarized on the basis of existing literature, theories and models. This review explores the differences in influences on fuel use between rural and urban areas. It also evaluates and identifies patterns and trends in domestic energy in urban/rural areas of Nigeria. From the literatures reviewed, it was seen that domestic energy is energy used at homes for cooking, heating, lightening, cooling, powering electrical appliances and pumping water. These energies can be sourced from different energy sources ranging from traditional energy (wood waste, animal dung, crop waste fuel wood, sawdust and charcoal) to the modern energy source (kerosene, liquefied gas and electricity). Looking at the two energy models used for this research, it was seen that electricity ranks the highest in energy ladder model and energy stack model, yet most households in Nigeria, approximately 100 million people lack access to it. It was noted that the key factors in the growth of household energy consumption are the number of households with access to energy supply, penetration rates of electric appliances, and the mount and efficiency of energy sources. The findings have shown that a lot should be done in ensuring that safer and cleaner sources of energy are available to rural households. Conventionally, availability, affordability and convenience of usage are critical issues to be taken into consideration when making choices among alternative energy sources that are available. There is the need for government’s intervention in making kerosene available to rural poor. This is the source of energy that was mostly used.

Abstract

Asphaltenes precipitated from the North Sea crude oil were subjected to hydropyrolysis to determine the percentage yield of hydrocarbon from asphaltene matrix. Open column chromatography which was performed on asphaltene hydropyrolysate gave a percentage recovery of 70 %, suggesting that this process is a veritable tool for the release of hydrocarbons trapped in asphaltene matrix.

Abstract

This report presents the investigation of red onion skin and the plant Rhizophoraracemosa as inhibitors of corrosion of samples of NST60-2 drill-pipe in drilling mud solution using the weight-loss immersion technique.  The inhibitive potentials of the two inhibitors were evaluated based on a determination of the corrosion rates in the presence and absence of the inhibitors and effectiveness of the two inhibitors at different levels of concentrations for room temperature of 28oC and elevated temperature of 125oC.  The results show that red onion skin is a much better inhibitor of the corrosion of samples of drill-pipe in drilling mud solution than the plant Rhizophoraracemosa.  The effectiveness of inhibition becomes significant only at concentrations of 200ppm for red onion skin and 300ppm for the plant Rhizophoraracemosa at room temperature.  At elevated temperature, the effectiveness of their inhibition is not reliable because a greater amount of inhibitor may be required for the protection of oil processing equipment and machineries.  The results of this work are expected to be used to improve the corrosion resistance of this drill-pipe for oil processing industries in Nigeria.
