ABSTRACT In the Buntsandstein gas fields of the Southern North Sea, the Volpriehausen reservoir is the main producing unit. This reservoir suffers often from the in-filling of the reservoir pore spaces by solid materials (salt plugs). Determining the reservoir quality of these fields based on seismic data alone has proved to be a major exploration challenge; the presence of salt-plugs in reservoir pore spaces seems to produce seismic responses that are similar at first sight to that of gas-f...
ABSTRACT Twenty-one outcrops of igneous bodies were studied in a small area (ca. 335 sq. km) of folded sediments west of Anyim River in the Lower Benue Rift. The extrusives occur mainly as basaltic to trachybasaltic tuffs and lapilli tuffs. The minor intrusives are found as basaltic and dolerite sills composed essentially of plagioclase (An,,), augite, with or without olivine. The major intrusives are dioritic small bodies considing of sodic plagioclase (An,,), biotite andor hornblende, and ...
ABSTRACT This research work presents findings of the extent and distributions of saline zone and the hydrochemical characteristics of the groundwater of Awe, Keana and Giza areas in the Middle Benue Trough of Nigeria.Staticwater levels(swl) of hand dug wells were measured andthe results used to generate hydraulic head data and hydraulichead map. The static water levels range from 1.0m to 13.5m at Awe, 1.0m to 4.5m at Keana and 2.2m to 9.2m at Giza. The hydraulic head maps for the three areas...
ABSTRACT. This topic was informed by the fact that the current approach to office information system in our educational institutions left much to be desired. The amount of paper records being used is extremely bulky with the resultant problems of storage and retrieval. In the University of Nigeria, in the last eighteen months, four staff audits have been conducted. These audits panel revealed sordid mal-practice arising from poor and slow inter-office communication. For example, from these a...
ABSTRACT Diabetes mellitus, a metabolic disorder that affects the body’s ability to make or use insulin, has become a major public-health issue globally. This is because of the numerous health problems it causes to humans including: brain damage, heart and renal diseases, circulatory problems, and death. The onset of diabetes mellitus can be due to various causes including genetic that leads mainly to development of Type I diabetes mellitus and the lifestyle of an individual that leads to o...
ABSTRACT Malaria is a health problem and drug resistance to antimalarial poses a great challenge to its treatment and control. Having a rapid activity against malaria parasites, artemisinins are the front line antimalarials. However, already there are reports on reduced response to artemisinins. Thus it’s important to monitor resistance in malaria risky areas. Merozoite surface protein (MSP) 1 and 2 genotyping has shown difference between isolates from primary and recurrent infections ...
ABSTRACT Studies show there is less ear damage by insect pests and increased soil fertility from maize/legume intercropping system. These are two main benefits with pre-harvest potential on ear rots incidence and severity which result into mycotoxins reduction. Therefore, in a two season study, impact of push-pull technology (PP), maize desmodium intercrop edged by Brachiaria or Napier grass, was assessed on incidence and severity of four common ear rots: Fusarium, Gibberella, Diplodia and As...
ABSTRACT The Northwest Olkaria prospect, Oserian Sanctuary, is part of the Greater Olkaria Geothermal Area located within the Kenyan rift valley in Nakuru County. It is bounded by the longitudes 360 15′E and 360 12′E with an estimated area of 30 km2. Studies previously done did not adequately cover the area to the North West hence no geophysical data is available on the resistivity of key concealed geothermal structural features like thin massive heat sources and shallow faults based on s...
ABSTRACT Control and management of human African trypanosomosis faces many challenges including limited available drugs that are stage specific and also toxic, treatment failures and post treatment CNS and cardiac pathology which might be fatal. Because of ethical considerations, trypanosomosis and drug trial studies are conducted using animal models which have drawbacks. It is therefore important to develop models that can address the current drawbacks and also develop enzymatic disease stag...
ABSTRACT There is an urgent interest initiated to develop clean energy resources with the aim of reducing exposure to environmental pollutants and explore model fuels that can hasten the achievement of clean energy combustion. In order to optimize the pyrolysis of binary transport fuels, diesel blends of ratios 1:1, 3:2 and 2:3 were each pyrolyzed at a contact time of 5 seconds in a quartz reactor at 1 atmosphere pressure, at a model temperature of 500 ºC. The surface morphology of the parti...
ABSTRACT Agrochemical industries are faced with inadequate supply of molasses that is the main raw material for ethanol production creating a need to develop an alternative feedstock. The use of sweet sorghum will alleviate the problem. Three sweet sorghum (Sorghum bicolor L. Moench) genotypes, EUSS10, EUSS11, and EUSS17 were tested against five controls, SS21, SS17, SS14, ACFC003/12 and SS04 to evaluate their ethanol yield potential, stability, and adaptability in Busia, Siaya and Kisumu Cou...
ABSTRACT Human Immunodeficiency Virus (HIV) infection remains a major global public health concern with 36.9 million people infected. The HIV health burden is most felt in Sub-Saharan Africa, where about 70% of the infection occurs. The unprecedented scale-up of access to antiretroviral therapy (ART) has improved the management of HIV and reduced HIV-associated morbidity and mortality. However, long term sustainability of this success requires treatment monitoring and surveillance of emerging...
ABSTRACT Spontaneously fermented milks are integral to human diets in many African communities. These products have found their way into the informal market posing a public health concern because their quality and safety is not ascertained. Consequently, there is need to isolate and identify microbial strains with superior fermentative qualities and attributes of health qualities as starter cultures to commercialize production as well as profile potential microbial hazards. The aim of this st...
ABSTRACT Studies have shown a decreased risk of atherosclerosis linked to the intake of fruits and vegetables rich in bioactive phytonutrients. This study investigated the effect of crude beet root betalains on low density lipoprotein (LDL) oxidation induced by hypochlorous acid (HOCl). Crude betalains antioxidant potential was determined by use of 2, 2 – diphenyl - 1 – picrylhyrayl radical (DPPH assay) and was compared to lycopene and ascorbic acid. HOCl oxidizing ability and betalains a...
ABSTRACT Hepatocellular carcinoma (HCC), a common type of liver cancer arising from progressive transformation of pre-cancerous dysplasia macronodules and hepatocytes is ranked as the fourth leading cause of death globally and a fifth cause of death in Africa. Several risk factors for HCC have been identified that include dietary and life style risks, significant genetic family history and predisposition to genetic mutation. It has been hypothesized that codon 249 of p53 gene is more suscepti...
