Vector Species Of Guinea Worm in West Akim District Of Ghana, And The Evaluation Of Abate As A Cyclopside

ABSTRACT Field studies were performed to identify the vector species o f Dracunculus medinensis. From these studies, Mesocyclops kieferi was implicated as a maj'or vector. Other vector species identified were Mesocyclops aspericornis and Thermocyclops inopinus. Studies were also carried out in the endemic villages using a questionnaire to ascertain the pattern of disease incidence during the years 1994- 1996. The results revealed that the socio-cultural practices of the people assist in promo...

Climate Change, Water Conflict, And Human Security In The Bawku Area Of Ghana

ABSTRACT The publication of the Fourth Assessment Report by the Intergovernmental Panel on Climate Change ignited several debates, including the security implications of climate change. While some authors have pointed out some forms of relationship between climate change and conflict, others have had contradicting views. This current study sought to unravel this nexus and to contribute our understanding of the supposed association in the Bawku Area of Ghana. Guided by the Hydro-Climatic Chang...

ABSTRACT The study examined the effects of information and communication technology (ICT) tools used in teaching and learning, which is a case study of Presbyterian Boys‟ Senior High School in Greater Accra Region. The study is underpinned by Valsiner‟s (1997) zone theory. A combination of qualitative and quantitative research designs were chosen for this study. Purposive sampling technique was used to select the senior high school teachers in Presbyterian Boys‟ Senior High School. In a...

Regression Analysis Of Academic Performance Of Potsin T. I. "Ahmadiyya Secondary School Students

ABSTRACT This research is based on the results of Senior Secondary School Certificate Examination (SSSCE) released by the West African Examinations Council in elective and core subjects of study at Potsin T. I. Ahmadiyya Secondary School from 2000 to 2003. The elective programmes of study are General Arts, Business, Home Economics and Technical subjects. The data also includes the gender and religious affiliation of candidates. The main objective of the study is to identify variables that sig...

Assessing Land Use And Land Cover Change In The Keta Municipality Of Ghana Using Remote Sensing

ABSTRACT  Coastal areas around the world are increasingly facing devastating disasters due to land use and land cover changes. Same can be said of Keta Municipality which experiences series of challenges such as unplanned urbanisation, intensive agriculture, flooding and coastal erosions. To design better solutions to these recurring problems, there is the need to understand the landscape and its interaction with its inhabitants. To achieve this, this study employed remote sensing techniques...

A Study Of Iterative Methods In Optimization

ABSTRACT Optimization techniques are called into play everyday in decision making processes involving resource allocation in almost every discipline. However, the development and implementation of algorithm for solving optimization problems are fraught with many difficulties and frustrations. The aim of this thesis has been to examine and identify some of the problems associated with the development and implementation of a class of optimization algorithms and to develop a means of improving u...

Comparing Reading And Understanding Levels Of Junior High School Students Who Read Electronic Texts With The Level Of Those Who Read Printed Texts

ABSTRACT An experimental posttest-only control-group design was used to assess the influence of electronic text on the reading comprehension of junior high school students of Akosombo Volta River Authority Junior High School No. 1. A convenience sample of 140 randomly assigned students was used for this research. Half of the students used passages from text read on screens while the other half used traditional print text passages. Data was collected during one class period in which the readin...

Impact Of Gold Mining Activities On The Water Quality Of The Lower Pra River

ABSTRACT  This study was conducted to assess the extent of Mercury (THg) contamination at four locations within the Shama-Mporhor Wassa catchment area of the Lower Pra River. Water, fish and sediment samples were taken twice with the longitudinal transect method at Daboase, Beposo, Bokorkope and Shama during the minor rainy season in October and at the apex of the dry season in March. Careful investigation of the Shama-Mporhor Wassa catchment area revealed that two of the locations Daboase a...

Molecular Diagnosis Of Hepatitis C Virus in Ghanaian Blood Donors

ABSTRACT  The geographical distribution of different types and subtypes and the prevalence of hepatitis C virus (HCV) vary significantly. Identification of HCV genotypes has become increasingly important for the clinical management and prognosis of HCV infections. Available evidence shows that HCV is endemic in West Africa, but there is little data on HCV genotypes present in Ghana. This study therefore set out to identify circulating HCV genotypes in healthy Ghanaians and determine the rela...

Statistical Analysis Of Reports On Domestic Violence In Ghana

ABSTRACT The incidence of the print and electronic media reports on violence and abuse in the domestic setting heightened the interest for this study and has therefore served as a major source of motivation for this research work. The work seeks to investigate the causes of domestic violence vis-à-vis the consequences of such acts. The major findings indicated that domestic violence in Ghana can best be described as violence against women and children. It was also discovered that domestic ...

Feasibility Of Teaching Quadratic Equations In Senior High School Form One

ABSTRACT The study addressed the curriculum problem of the placement of the teaching and learning of quadratic equation in the Senior High School. Its purpose was to assess the ability of S.H.S 1 students to solve quadratic equation by investigating their performance, using four methods. Stratified sampling method was used to select four schools in four districts in the Central Region. Eight classes were randomly selected for the study. The sample size was 286 of which 160 were girls. A pret...

Genetic Markers Associated With Striga Gesnerioides Resistance And Seed Sizes In Cowpea [Vigna Unguiculata (L.) Walp.] Inbred Lines

ABSTRACT Production of cowpea is severely hampered by different races of the parasitic weed, Striga gesnerioides. Cultivation of Striga-resistant cowpea is the most reliable protocol to effectively combat the parasite. The current study reported the identification of genetic markers associated with multi-race-Striga resistance and seed size across the genome of cowpea RIL populations. The landrace GH3684 from Ghana was tested for resistance against all known races of Striga gesnerioides in ...

Estimation Techniques In Generalized Linear Mixed Models With Application To Disease Impact Modelling

ABSTRACT This study applies the theory of Generalised linear Mixed Models (GLMMs) to survey data on disease impact in Ghana. It determines the variables that are responsible for making dependent members of households feel the impact of illness and/or death for three identified types of households. It assesses four models in terms of these variables generated using the Maximum Mean PseudoLikelihood (MMPL) and the Residual Mean Pseudo-Likelihood (RMPL) techniques in SAS. For all four models c...

Cancer Risk Assessment of Patients Undergoing Computed Tomography Examination at the Korle-Bu Teaching Hospital (KBTH)

ABSTRACT  The aim of this study is to estimate the effective dose and assess the lifetime attributable risk of cancer incidence of patients undergoing computed tomography scan at the KorleBu Teaching Hospital. Data on Volume CT Dose Index ( ) and Dose Length Product ( ) displayed on the scanner control console was recorded after confirmation of the results by performing independent checks on a phantom. The effective doses were estimated using the displayed and the anatomic region specific co...

Factor Analysis Of Applicants' Choice Of Cape Coast Polytechnic

ABSTRACT It is of great interest and concern to human beings to know why we do what we do in every sphere of life. Of particular interest is education because, it is a key factor in the developmental process or, in the affairs of every developing nation of which Ghana is one and that is what motivated the researcher into finding out the issues Cape Coast Polytechnic students consider in choosing to study at the Cape Coast Polytechnic. Purposive sampling technique was used to select the stude...
