The growing demand for potable water supply has been a major challenge in Ado-Ekiti, Southwestern Nigeria. Delivery of good quality water by the Ekiti State Water Board to individual consumers in the required quantity and under satisfactory pressure is suspect. Even in areas that are supposedly served by piped water, the supplies to homes are extra-ordinarily intermittent in flow. This inevitably undermines the confidence of consumers, resulting to complaints and possibly the use of water fro...
ABSTRACT Geological mapping and geochemical analysis of rock samples were made on pit rocks from Obuem Mining Concession found within the Birimian of Ashanti Belt of Ghana, in order to determine the nature of gold mineralisation. The study area consists of metavolcanics and metasediments with few intrusions of granitoids. Metasediments such as phyllites and schists as well as metavolcanics of andesitic and basaltic origin were sampled and analyzed for their major and trace element contents us...
ABSTRACT African trypanosomiasis is a disease caused by the parasitic protozoans of African trypanosomes. Despite several efforts at chemotherapeutic interventions, the disease poses serious health and economic concerns to humans and animals of various sub-Saharan African countries. Commercially available drugs such as suramin, eflornithine, pentamidine, melarsoprol and nifurtimox have reported cases of undesirable side effects, drug resistance, and difficulty in regimen application. Studies ...
ABSTRACT Subsurface samples of Mamu Formation from Ezimo 1235 and Enugu 1327 wells, located within the Anambra Basin were examined for organic geochemical characterization and biomarker content in order to determine the lithofacies association, hydrocarbon potential as well as the palaeodepositional environment. The sediments are made up of siltstone, dark coal, highly fissile shale and mudstone. Selected samples, made up of shale and coal from both wells were subjected to Rock Eval and gas c...
ABSTRACT This project is based on the results of candidates who sat for the Senior Secondary School Certificate Examination (SSSCE) conducted by the West Mrican Examinations Council (WAEC). The main objective of this project is to determine whether performance in SSSCE core subjects namely Core Mathematics, Integrated Science, English Language and Social Studies for the five-year period from 2001 to 2005 depended on sex. The data were obtained from the West African Examinations Council-for th...
ABSTRACT Accra has been experiencing periodic flooding that affects properties and lives. For instance on 41h and Sib June 1994, 8 persons lost their lives and 80 million cedis worth of properties belonging to Paloma Company were destroyed due the floods that occurred at that time. The government seeing the dangers involved. commissioned institutions such as Ministry of Works and Housing, Tourism and Country Planning and City Engineers to identify such areas and adopt measures that will ...
ABSTRACT This study focused on senior high school students’ perception of their computer laboratory learning environment and how the use of computers affects their learning in urban and community senior high schools. Data was obtained with the Computer Laboratory Environment Inventory questionnaire, administered to 278 second year senior high school students. The sample consisted of 171 males (61.5%) and 107 females (38.5%) with a mean age of students being 17.4 years. The data were analyze...
ABSTRACT The emergence of widespread drug-resistance strains of the malaria parasites militates against strives for more potent antimalarial drugs. Therefore, a renewed effort to search for new drugs from medicinal plants focusing on the mangroves in Ghana has become imperative. Hence, this study aimed at evaluating the in vitro and in vivo antimalarial activity and toxic effect of the crude extract of Avicennia africana leaf in rats. The pulverized dried leaves were extracted with 70% ethano...
MODELING HUMAN DEVELOPMENT INDEX USING DISCRIMINANT ANALYSIS By Iwuagwu, Chukwuma E. Nwosu, Moses Obinna Department of Statistics Abia State Polytechnic, Aba Abstract The basic objective of human development is to create an enabling environment for people to live long, healthy and creative lives and it is composite statistic of the life expectancy, education income per capita indicators which are used to rank countries into tiers of human development. The paper determined the critical variab...
ABSTRACT The study adopted a pragmatist approach to assess farmers‟ vulnerability and adaptation to drought in three agro-ecological-locations in Ghana. It analysed the variations in precipitation deficits by using precipitation values for 1983-2014 period. It also assessed the variation in drought vulnerability, farmers‟ adaptation and barriers to drought adaptation. The cross-sectional survey design was utilised. A random sample of 326 farmers and six purposively selected lead farmers p...
ABSTRACT The Minimum Description Length (MDL) provides an attractive basis for statistical inference and model selection. However, little is known about the relative performance of its different formulations in Asymmetric Price Transmission (APT) modelling framework. To explore these issues, the study investigates different formulations of the MDL against commonly used alternatives (AIC and BIC) in terms of their ability to recover the true asymmetric data generating process (DGP) under vario...
ABSTRACT This study investigated the impact of ICT three initiatives as perceived by Wiawso College of Education tutors at an independent school in Sefwi Wiawso. A qualitative data was gathered for this Case Study by administering questionnaire to 43 tutors of the college and two administrative staff. Data were analysed using descriptive statistics. First and foremost, evidence was found of an overall increase in the use of ICT since the three initiatives were implemented. Secondly, the provi...
DEVELOPMENT OF STATISTICAL PROGRAM FOR DISCRIMINANT ANALYSIS FOR MIXED VARIABLES USING R-CODE, By Iwuagwu, Chukwuma E. Ibegbulem, Zebulon O. Nwosu, Obinna M. Ekwuribe, Celestine. Department of Statistics, Abia State Polytechnic, Aba, Abia State. Abstract Discriminant analysis is a statistical technique that tried to predict on the bases of one or more independent variables. Whether an individual or other objects can be placed into a particular category of a categorical dependent variables. T...
The ethanolic extract (crude extract) was successively extracted with n hexane, chloroform, water, 103 aqueous methanol and n_hexane to give the corresponding fractions. The crude exfract, 103 "aqueous methanol, vvater soluble and n-hexane fractions of the root of .c_.africana, were screened for antimicrobial activity and chemical constituents. The n-hexane fraction was chromatographed on a column of silica gel to give a number of fairly pure components. The infrared spectra of the comp...
Studies of physico-mechanical and morphological properties of pure and -cellulose reinforced blends of polystyrene (PS) and poly (vinyl acetate) (PVAc) are reported in this work. The compression moulded articles of the blends of different compositions (10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20 and 90:10, PS/PVAc) were tested for mechanical performance, absorption behaviour, void activity and morphological arrangements. Comparison of mechanical properties such as tensile...
