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...
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 ...
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...
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...
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...
ABSTRACT Background: Malaria predisposes children in areas where malaria is endemic to concurrent bacteraemia. In the tropics, co-infections of both diseases are prevalent and are the leading causes of paediatric hospital admissions, morbidity and mortality. Methods: A cross-sectional study was conducted to investigate the prevalence of coinfection of malaria and bacterial bloodstream infections among 232 children under 13 years who reported to three healthcare facilities in Accra and Dodowa ...
ABSTRACT This research investigated the efficacy and chemistry of selected traditional medicines (TM) used in the treatment of schistosomiasis and also explored their antitrypanosomal potential. Crude extracts were obtained by successive extraction of dried herbs with dichloromethane and methanol while aqueous herbal preparations were extracted with dichloromethane and butanol. Biological activity was conducted by screening the crude extracts against the schistosomula (NTS) and adult worms of...
ABSTRACT Background: Hearing Sensitivity is the commonest form of hearing. Occupational hearing loss has received little or no attention in most industries and has left many employees with hearing loss of varying degrees after retirement. The navy has not been spared in this area as some of its personnel exposed to varying levels of noise. This study was carried out to determine the prevalence of hearing loss and to investigate the risk factors associated with hearing loss among naval personn...
ABSTRACT Cleaning is central to any food process operation and it entails the removal of soils from processing equipment, food contact surfaces and production floor. It is done with the aid of a cleaning agent and key among several are the soaps and detergents. Most detergents currently used in the industry are petroleum based, which are not easily biodegradable. Moreover they are imported, and add costs to the operations of industry. The use of locally available material that are biodegradab...
ABSTRACT This study presents the mineralogical, textural and geochemical characteristics of the regional Maastrichtian Ajali Sandstone in Anambra Basin, SE Nigeria. The intent is to highlight possible constraints on the chemical weathering conditions of the source materials on one hand, and to infer the provenance on the other hand. The investigation approach involved field studies and collection of samples from 12 different outcrop locations, followed by laboratory studies involving grain-si...
ABSTRACT Acoustic effects such as absorption/amplification of acoustic phonons, Acoustoelectric Effect (AE) and Acoustomagnetoelectric Effect (AME) were studied in Carbon Allotropes. In this thesis, the Carbon Allotropes considered are Graphene Nanoribbon (GNR), 2-dimensional Graphene sheet, and Carbon Nanotubes (CNT). The Boltzmann transport equation (BTE) and the phonon kinetic equation (PKE) were used. All results were analysed numerically and graphically presented. Using BTE for Armchair...
ABSTRACT The infestation of cashew by Analeptes trifasciata is on the increase and this poses serious threat to cashew cultivation in Nigeria. Base-line information on the distribution and behavioural ecology of A. trifasciata in Nigeria is needed for its control. This study was conducted to provide more information on the morphology, distribution and behavioural ecology of A. trifasciata in Nigeria. A survey of the geographical spread of A. trifasciata infestation was conducted in 25 cashew ...
ABSTRACT Inherited Glucose-6-Phosphate dehydrogenase (G6PD) deficiency in humans results in hemolytic anaemia. The enzyme G6PD provides a crucial link in a series of biochemical reactions which occur in the red blood cell that leads to the steady state accuralation of NADPH, reduced glutathione by glutathione reductase, and the removal of potentially dangerous organic peroxides which, if not scanvenged, may result in the formation of radical species of oxygen which damage the energy generatio...
Abstract Biometric systems have overtime served as robust security mechanisms in various domains. Fingerprints are the oldest and most widely used form of biometric identification. A critical step in exploring its advantages is to adopt it for use as a form of security in already existing systems, such as vehicles. This research work focuses on the use of fingerprints for vehicle ignition, as opposed to the conventional method of using keys. The prototype system could be divided into the foll...
Abstract Merozoite surface protein-119 (MSP-119) specific antibodies which include processing inhibitory, blocking and neutral antibodies have been identified in individuals exposed to Plasmodium falciparum. Here we intend to look at the effect of single and multiple amino acid substitutions ofMSP-119 on the recognition by polyclonal antibodies from children living in Igbo-Ora, Nigeria. This would provide us with information on the possibility of eliciting mainly processing inhibitory antibod...
