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...
ABSTRACT Cocoa kombucha (CK) is a new alcoholic beverage developed from cocoa which has many health benefits, so its antioxidant activity and anti-proliferative activity in Jurkat P9 cancer cells were determined and compared to unfermented cocoa and selected standards. The antioxidant activity of CK extract was determined by DPPH assay and total phenolic content, as well as its iron reducing power. The MTT assay was used to determine the anti-proliferative activity of cocoa kombucha. Results ...
ABSTRACT Many married couples experience their relationship changes over time. During the first years of the relationship, they had spent many evenings just talking with each other. They wanted to share joys, hurts, and hearts. There was closeness between the two of them that just made them want to get to know one another more and more. This project is about those in need, it provides information, resources and marriage counseling through an online designed base. It also helps in linking thos...

ABSTRACT In this Thesis, The Personal Services Locator helps users to find personalized workers or “Handymen” as fast as possible. The issue of finding a person or an individual to do a certain job has always been around, even though it has been reduced with the use of adverts and various social media, it’s not as fast and as efficient at locating people. This application finds the closest person(s) with the services running depending on which personalized service the user is looking fo...
ABSTRACT The n-butanol fraction (nBF) of Desmxhvw adscendens , a plant used for the management of asthma, is' an inhibitor of NADPH-dependent cytochrcire P-450 (CYP) reactions. Its mechanism of action as an inhibitor is however net knewn. In this study, flavoprotein reductase activity, spectral changes associated with binding and spectral properties of reduced cytochrcme c and CYP were used to investigate the mode of inhibition. nBF reduced cytochrcme c but not CYP directly. In the presence o...
ABSTRACT The proposed system is a dynamic model of social media monitoring tool with sentiment analysis. Social media platforms contain a lot of data which might be considered ambiguous to businesses/organizations. Most organizations make use of social media platforms for advertisement as they reach a large crowd in a short period of time and are also more affordable compared to other options. Businesses find it difficult to have a clear vision/insight on how well their business has grown aft...
