Abstract Ceiba pentandra, Colagigantea,Lanneawelwitschii,Militia excelsa (all non-leguminous) and Milletia zechiana (leguminous) are among the various tree species retained on cropping fields in the Akuapem District of Ghana, but little is known of the actual contribution of these species to soil fertility improvement. Leaf litter samples from the above-mentioned non-leguminous species were analysed to determine their nutrient content. Leaf litter production was also quantified monthly over a...
ABSTRACT This study describes and identifies palynomorphs (spore/pollen and dinoflagellates) from different levels of the CTP-1 well succession in the offshore Tano Basin in order to establish palynostratigraphy of the studied sediments. The palynomorphs are used as an age tool for the sediments after comparison with other species or sediments reported from other parts of the world, especially the North Gondwana Province (ASA) region. Sedimentary Organic Matter is used to establish palynofaci...
ABSTRACT A total of 484 children aged between 1 -10 years who reported at the emergency unit of the Department of Child Health, Korle Bu Teaching Hospital with clinical malaria were recruited for this study. The children were categorized into four main groups of clinical malaria namely, severe malaria anaemia (SA), cerebral malaria (CM), uncomplicated malaria (UM) and intravascular haemolysis, or bloody urine (IVH). The aim of the study was to determine the role of complement activation in th...
ABSTRACT In this study, the effective dose and its associated cancer risk were estimated for adult patients undergoing the five most common types of CT examinations (head, neck, chest, abdomen and pelvis) at Sweden Ghana Medical Centre (SGMC) in the Greater Accra Region of Ghana. Two main methods were employed in the study: patients’ data collection and phantom measurement to verify the patient data. The effective doses were estimated using the dose length product (DLP) from the control con...
ABSTRACT The suitability o f five Schistosoma genus-specific monoclonal antibodies (MoAbs) (Sh3/34.10, Sh3/38.2, Sh4/14.3, Sh5/32.30 and Sh5/34.10) in detecting schistosome antigens in infected human and cattle was evaluated. These antibodies were employed in various diagnostic assays to diagnose human and animal schistosomiasis. Extant MoAb secreting hybridoma cells were first propagated in culture to produce the MoAbs. The culture supernatants containing secreted antibodies were analysed by...
ABSTRACT It is generally acknowledged that availability of data remains critical to effective monitoring of poverty indicators and evaluation of policies and programmes towards alleviating poverty. The paucity of data has reduced the frequency of measuring poverty indicators at the national and regional level. District level poverty indicators are yet to be estimated since sampling designed data collected can only provide national and regional level indicators. This thesis applied multiple im...
ABSTRACT Like the developing and developed countries in the world, Bayelsa State has also embraced and is involved in the processing of various aspects of e-government, particularly in its ministries, agencies and departments.The study is based on jugdemental methodology in using to solve the thesis problem,whose objectives are to know the main obstacles in implementing e-government in Bayelsa State, to know which obstacle have the most effect in implementing e-government in Bayelsa State, ...
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 A study was made of the effect on pepper quality of the traditional method of processing the "Balancotta" variety of Piper nigrum (black pepper). The study comparatively considered the microbiological quality, drying method, drying rate, colour and appearance, washing or cleaning method, prior to fermentation or heaping as well as an alternative method - heat treatment processing of the commodity. Using a solar dryer as a drying apparatus resulted in 9.8% moisture content of the sam...
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 b...
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 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...
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY 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 Progra...
