ABSTRACT The persistent prevalence of Counterfeit and substandard drugs poses a clear and present danger globally. Its higher degree of occurrence and under-reporting in developing nations especially in Africa and Asia is of great concern. Antibiotics are amongst the most used and abused in developing countries and as such, the need for its constant surveillance cannot be over emphasised. This study involved the assessment of the quality of three commonly used therapeutic groups of antibioti...
ABSTRACT The study objectives are to determine the key factors that may be accounting for birthweight of infants, estimate its distribution, prevalence and proposes a statistical model that can be useful in epidemiological studies in Ghana. Both estimation (Linear) and classification (Logistic) analysis was conducted using data from GDHS. Covariates found to statistically associated with newborn’s weight are gender, size of child at birth, region, wealth index, birth order, total number ch...
ABSTRACT Economic gold mineralization at Amoanda project area is hosted mainly in the footwall quartzite of the Banket series of the group. Igneous rocks generally are barren in both Amoanda project area and Greater Damang project area. However, core logs and sections from extensive deep drilling at Greater Damang has identified a deep-seated mineralized diorites body whereas igneous intrusive rocks in Amoanda which is suspected to be having similar characteristics show no gold mineralization...
Abstract Samples of Sarotherodon melanotheron obtained from water bodies of different pollution histories, that is, a site on the Volta lake near Ada, the Fosu lagoon at Cape Coast and aquaria containing the herbicide, 'Roundup', were used to investigate induction of hepatic cytochrome P-450 monooxygenase enzyme system (CYP) and glutathione-stransferase (GST) in response to pollutants. Total microsomal protein concentration was determined by the FolinLowry method. The activity of NADPH cytoch...
ABSTRACT An integrated petrographic and geochemical study of the Anyaboni Formation, Kwahu Group, Voltaian Supergroup in Ghana was carried out to infer the provenance, tectonic setting, paleoweathering and paleoclimate conditions and uranium mineralisation potential of the basin. Twenty representative rock samples were collected from the Anyaboni Formation in Asesewa and its surrounding areas for petrographic and whole rock geochemical studies. The major elements were analysed by ICP-OES and ...
ABSTRACT The extensive redundancy in the use of invasion ligands by Plasmodium falciparum, and its unique ability to switch between invasion pathways have hampered vaccine development. The Dd2 and W2mef strains of P. falciparum have been shown to change from sialic acid (SA)-dependent to SA-independent phenotypes when selected on neuraminidase-treated erythrocytes. Following an observation of increasing ability of Dd2 to invade neuraminidase-treated cells when cultured for several weeks, a sy...
ABSTRACT HIV/AIDS is a major public health issue, having killed several millions of people, with subSaharan Africa mostly affected. Management of HIV infection, over the past decades, has been carried out using antiretroviral (ARV) drugs. Although antiretroviral therapy (ART) has decreased morbidity and mortality from HIV, long term therapy is associated with toxicity and severe side effects. These side effects have been attributed in part to ART-induced mitochondrial toxicity due to mitochon...
Cowpea, Vigna unguiculata, is an important human and livestock protein source in Nigeria, but its production is constrained by ravages of pests and climate change. Conventional breeding efforts used to fortify it against these constraints had resulted into its narrow genetic base. In order to overcome this challenge, other mutation procedure such as physical and chemical mutagens could be used. Nevertheless, information on gamma and ultra-violet (UV) irradiated cowpea seeds and pollen ha...
ABSTRACT To Plagiarise is to include another person’s work, idea, method or results without due acknowledgement. In this work, we developed an innovative algorithm to detect external plagiarism in documents, using a combination of Word-n-gram and string matching technique. The suspicious document was split into sentences and further split into word n-gram and each n-gram was used to perform a pattern match on a standard PAN-09 corpora. We discovered that the best plagiarism detection occur...
Maize and soyabean are among the staples in the world. Their sustainable production through the use of synthetic fertilizer causes soil degradation and ground water contamination. An alternative means of boosting and sustaining the production of these staples through the use of rhizobium and mycorrhiza have been reported but there are contradictory reports on interactions between the two organisms. Therefore, the objective of this study was to assess the influence of Rhizobium japonicum ...
ABSTRACT Energy from hydro-electricity is the cheapest form of power generation in this country. The Volta River Authority can however generate power optimally if water levels within the dam is between 240ft and 280ft. This is not always the case, since the only source of water for the dam is rainfall, which is also random and dependent on weather conditions. Knowledge of the water level within any month of the year will therefore be very useful in the production, distribution and management ...
Mature apple trees were sprayed using a Knapsack mistblower fitted with 3 different nozzle systems, one of which provided an induced electrostatic charge on the spray droplets. Spray distribution was assessed by examining fluorescent tracer deposits on Kromekote cards which had been positioned in different parts of the tree canopy. Subsequently, bioassays with codling moth (neonate larvae) and formulations of cypermethrin examined the biological effect of deposits. Small uncharged droplets (3...
ABSTRACT Airborne particulate matter (APM) composition has been studied at the Abuesi area. Aerosol samples in two size fractions were collected over a period of 3 months using the Gent stacked filter unit (SFU). Energy Dispersive X-ray Fluorescence Spectroscopy (EDXRF) was used to measure concentrations of up to 28 elements at the INFNAccelerator Laboratory, University of Florence, Italy for the coarse fraction which accounted for 53.84 % of PM10 aerosols in the Abuesi area. Mean values of 4...
ABSTRACT Bulinus truncatus and Biomphalariapfeifferi were cultured in varying concentrations ofseawater to study the effect of salinity on the survival and growth of adults and juveniles. The eggs were investigated for their hatchability. The experiment was conducted over a period of seven weeks for the snails while the eggs were studied over a two week period. Daily and weekly percentage mortality were determined . Weekly changes in weight and shell length was determined and used as an index...
ABSTRACT Over the years, measuring inequality based on the distribution of income has been a major concern to economist. Inequality has had a broader concept than poverty in that it is defined over the entire population not just for the portion of the population below a certain poverty line. The Gini coefficient satisfy many desirable properties of a good measure of inequality such as mean independence, population size independence, symmetry, and Pigou-Dalton Transfer sensitivity. The empiric...
