ABSTRACT Insecticide-treated nets (ITNs) for personal protection against mosquito bites have proven to be practical, highly effective, and cost effective intervention against malaria infection. Bungoma South District records malaria as the most frequently diagnosed condition in outpatients at health facilities and is the principal cause of death at the district hospital. Despite the report that ITNs have high impact on reduction of vectors of malaria, sporozoite rates, morbidity and mortality...
ABSTRACT Urinary Tract infection (UTI) is a serious infection causing illness in infants and children. It represents one of the most common diseases encountered in medical practice today. Despite the widespread availability of antibiotics, it remains the most common bacterial infection. Antimicrobial susceptibility testing therefore provides information that allows physicians to select the most appropriate antimicrobial agents for treating these infections and give the most effective antibiot...
ABSTRACT The ameliorative potential of Psidium guajava leaf ethanol extract on Paraquat induced toxicity and oxidative stress in Albino Rats were investigated. Thirty (30) healthy male wistar rats were divided into five groups of six animals each. Group 1 served as the normal control (NC) and received normal saline, Group 2 (Intoxicated control) received 3.5mg/kg of paraquat. Group 3 (PG200) received 200mg/kg PG leaf extract + 3.5mg/kg PQ, Group 4 (PG400) received 400mg/kg PG leaf extract + ...
ABSTRACT Adolescents regularly participating in sports and do not meet their energy intake may develop several medical conditions, such as disordered eating, menstrual dysfunction, and decreased bone mineral density, collectively referred to as the Female Athlete Triad (FAT). Limited data is available on components of FAT in adolescent athletes of African descent. This study’s aim was to investigate the presence of the components of the female athlete triad amongst a group of junior long fe...
ABSTRACT The use of raw maize cob (rmc) and activated maize cob (amc) as a low-cost natural adsorbent for the removal of Pb2+ and Cu2+ ions from simulated waste water was studied. Batch experiments were conducted to determine the effects of varying contact time, initial metal ion concentration, adsorbent dosage, pH and temperature of adsorption on adsorption equilibrium quantity (qe ) and percentage removal (% R). % R increased with increasing adsorbent dosage for the two metal ions. It also...
ABSTRACT The major goal of this research work is to determine the dynamic buckling load of a viscously damped imperfect quadratic-cubic elastic model structure, which is modeled by a nonlinear differential equation containing a load parameter. For a structure with small imperfections and subjected to step loading , the equation contains two small independent parameters, upon which asymptotic expansions are initiated. The nonlinearity is quadratic-cubic in nature and multiple-scaling two-timi...
ABSTRACT This study focuses on a model for reengineering and optimization of legacy file database which are in decay and have faced mutilation in most institutions and organizations in Nigeria. The model provides a systematic method to optimize a legacy file using open source database management system software which transforms the optimized data into digital format which now can be migrated using a designed network platform on a fiber optics backbone. This study is therefore necessitated by...
ABSTRACT In Cloud Computing, users connect to the ’Cloud’, appearing as a single entity as opposed to multiple servers. This work seeks to solve resource managerial problems ranging from server maintenance cost, risk of loss of data, internal security issues, and availability of data for proper decision making. This work presents to tertiary institutions a model for designing a scalable and cost effective platform for institutional resource management on the cloud. The platform is called...
ABSTRACT The prevalence of vitamins A and C deficiencies (VAD and VCD) in Kenya are 84 % and 45 % respectively, pointing towards health hazards among human beings. The deficiencies are mainly attributed to poverty and limited accessibility to expensive but rich food sources that contain vitamins A and C. Fruits and vegetables are however cheaper and easily available as sources of vitamins A and C. These are grown in various soils and are consumed at various stages of maturity thus being facto...
Abstract In urban transportation or freight distribution, the use of an initial distribution plan, although necessary, is by no means sufficient to address unexpected events such as mechanical failures, vehicle breakdown, total loss of transaction records that are likely to occur during delivery execution and may have adverse effects on system performance. These events cause deviations between the actual and desired state during the execution of the schedule or even after the schedule. Recen...
ABSTRACT The maize weevil, Sitophilus zeamais (Motchulsky), the lesser grain borer, Rhyzopertha dominica (Fabricius), and the Angoumois grain moth, Sitotroga cerealella (Oliver), are serious pests of stored grain in Kenya. The control of these insect pests relies heavily on the use of synthetic insecticides by better off farmers; but there is an increasing cost of application and erratic supply in developing countries. In addition, small-scale farmers cannot afford these commercial products a...
Linear Programming is a subset of Mathematical Programming that is concerned with efficient allocation of limited resources to known activities with the objective of meeting a desired goal of maximization or minimization of a function. Linear Programming determines the way to achieve the best outcome (such as maximum profit or lowest cost) in a given mathematical model, given some list of requirements as linear equations. Linear Programming can be applied to various fields of study - business...
ABSTRACT The thrust of the study which carried out in the Cenozoic Niger Delta is to infer and predict potential Petrophysical properties and hydrocarbon presence in unexplored areas proximal to producing areas in the eastern flank of Cenozoic Niger Delta, Nigeria, using seismic data and analogue proximal well data set from a producing area for subsurface reservoir characterization. Seismic and offset well dataset were used as input dataset to carry out Petrophysical evaluation, Seismic inte...
ABSTRACT Interpretation of structures and reservoir characterization using 3D seismic cube and well data pose great challenges in mapping because of their complexities especially in structural deformations, and where identification of reservoir facies is a major challenge to plan delineation, field appraisal and development drilling. Thus, the project work takes a model approach. The ―DIBA‖ Field in the Niger Delta contains hydrocarbons that are largely trapped in sandstones and unconsol...
ABSTRACT An integrated seismic interpretation using 3-D seismic data, check shot data and a suite of well logs for four wells were analyzed with the Petrel (seismic to simulation software). The objectives were to carry out a detailed formation evaluation, reservoir characterisation and a 3-D assisted structural interpretation of the densely faulted oil field in the coastal depo-belt of the Niger Delta. RMS amplitude, instantaneous frequency map and interval average extraction maps were extra...
