Abstract: The present study was aimed at analyzing the chemical composition of the crude extract of cactus pear (Opuntia ficus-indica L.) cladode and examine its suitability for fungal culture media. For this purpose cactus pear cladode samples were collected from Haramaya University campus Model School area. The chemical composition analysis was done according to standard procedures. The growth of five fungal species (R. stoloinfer ATCC 1052, P. digitatum ATCC 2560, A. niger ATCC 1232, T. a...
Abstract A 4-D seismic data comprising of two 3-D seismic volumes acquired at different vintages were successfully applied to identify the presence of by-passed oil opportunities in the water-driven reservoirs in an offshore area of bonny island in south-south part of Nigeria. Cross-plots of rock attributes from well data were carried out to validate their sensitivity to reservoir fluids and lithology and to constrain the interpretation of the time lapse inversion results. 4-D inversion of ...
Abstract: Helicobacter pylori is a small, spiral-shaped bacteria that lives on the surface of the stomach and duodenum. H. pylori is closely associated with onset of diseases such as gastric ulcers, duodenal ulcers, gastritis and gastric cancers. The aim of this study was to determine the allelic and genotypic frequencies of ABO blood group system and their associations with H. pylori infection among 384 patients with gastrointestinal complaints in the Ejere and Amaro Helth Center. Stool sam...
ABSTRACT The microbial quality of materials and final products of Chemical and Allied Products Limited (CAPL), rentable paint industry in Lagos area were analyzed. The bacterial population in the fresh paint samples monitored at two weeks intervals for a period of ten months ranged from 16x 10 - 7x10 ml while the fungal population ranged from 10 x 10-55 x 10 cfu/ml. The isolated bacterial sits were identified as Bacillus polymyxa, B. brevis, B.laterosporus, Proteus mirabilis, Escherichia coli...
Abstract: For centuries, maize producers in sub-Saharan Africa have been plagued by post-harvest losses from insect infestation and mould infections, with small-scale producers representing the most vulnerable populations. Participatory on-farm trials were conducted to assess the effectiveness of triple layer hermetic (PICS™) bags for storage of maize in small-scale farmers’ stores in rural villages in Makueni County,Kenya. PICS bags are three-layer hermetic bag-system that forms a barri...
ABSTRACT In an effort to provide information that can guide prevention strategies, this study determined the risk factors for HIV infection in Namibia and estimated the potential for HIV prevention. The study adopted a cross sectional research design with a sample of 14296 VCT clients from Oshana, Khomas and Kavango regions of Namibia for the period of 2009 to 2012. A multivariate logistic regression analysis was used to identify risk factors for HIV infection among VCT clients. For risk fac...
ABSTRACT Rubella is a vaccine-preventable, mild rash-inducing viral disease with complications that include a spectrum of birth defects in the developing fetus, especially if the infection is acquired in the early months of pregnancy. Consequently, the primary objective of global rubella control programs is prevention of congenital rubella infection and associated birth defects. Despite the availability of safe and effective vaccines, and the elimination of the rubella virus in many developed...
ABSTRACT This study focused on application of purchasing concept and its implications on organizational objective service industry (a case study of Imo Transportation Company (ITC). To carry out he research work some of the find out the problem faced by the from in purchasing their service. -it ascertain the possibility of applying the purchasing concept and its implications on organizational objective service purchasing. -To recommend efficient and effective ways of purchasing Imo Trans...
ABSTRACT Leishmaniasis is a parasitic infection that affects mostly tropical and sub-tropical regions of the world and caused by diverse pathogens that belong to the genus Leishmania. The pentavalent antimonials developed in 1945 are still first line treatment drugs for both cutaneous and visceral leishmaniasis while amphotericin B is a second line treatment drug. These treatments come with toxic side effects even at effective doses and the lack of vaccine demand the urgent need for new anti ...
ABSTRACT Specific and sensitive tests for the detection and typing of rotavirus strains are essential for a more assessment of the epidemiology of rotaviral infection in a community. In this study, 200 stool specimens obtained from October, 1999 to March, 2000 from neonates at the Babies Unit of the Korle-Bu teaching and Legon Hospitals were examined. Group A rotavirus was detected in 30% and Non-group A in 2.5% of the samples tested by either enzyme-linked immunosorbent assay (ELISA) for th...
ABSTRACT The purpose of this report was to analyze computer worms, their past, present and future, threats posed and recommend suitable solutions to mitigate and eradicate these worm threats. This study was carried out on kengrow industries. Major focus of this report is on computer worms that exploit computer networks. Computer worms are a type of malicious self replicating software or programs that are designed to infect multiple remote computers in an attempt to harm and cause grave damage...
Abstract Brucella spp. and Rift Valley fever virus (RVFV) are classified as priority zoonotic agents in Kenya, based on their public health and socioeconomic impact on the country. Data on the pathogen-specific and co-exposure levels is scarce due to limited active surveillance. This study investigated seroprevalence and co-exposure of Brucella spp. and RVFV and associated risk factors among slaughterhouse workers in Isiolo County, northern Kenya. A crosssectional serosurvey was done in all ...
The photovoltaic (PV) industry requires efficient cutting of large single and multi-crystalline (sc- and mc-) silicon (Si) wafers. Historically multi-wire slurry sawing (MWSS) dominated, but the higher productivity of diamond-wire-sawing (DWS) holds promise for decreasing PV costs in the future. While surface texturing of DWS wafers is more complicated than of MWSS wafers, especially in mc-Si wafers, nanotexturing has been shown to overcome this challenge. While the benefit of nanotexturing i...
ABSTRACT As reservoirs become more complex and drilling operations more expensive, the need to reduce both inefficiencies and costs for constructing and analyzing high quality static models is essential. The effective and efficient production of petroleum from a reservoir lies on the proper characterization of the reservoir. Once the static model resulting from reservoir characterization is satisfactory and heterogeneities taken care of, it is but evident that the uncertainties will be minimi...
