ABSTRACT Five Upper Amazons cocoa clones, namely NA33, PA150, PA7, SCA6 and SCA9 were selected for this study. The objective of the study was to ascertain the resistance level of the resistance to the CSSV disease. Test parents were clonally multiplied and inoculated and the expressed leaf symptoms studied. The difference observed in the parents were used to initiate hybridization. Mentor pollen technique was used to induce self-fertilization. Clonal multiplication was done by budding...
ABSTRACT Competitive Binding Assay methods have been used to determine the serum levels of 25- hydroxyvitamin D^ in healthy Ghanaians and patients suffering from cirrhosis of the liver and chronic renal failure. Although the assay followed fairly standard methods as used by several workers, an improvement in stability and sensitivity was obtained by the use of gelatin in the buffer; the final assay buffer being 0.02M phosphate buffer, pH 7 ,C with 0.1% gelatin. Though rachitic rat s...
ABSTRACT This study was undertaken to assist DBE ONE „A‟ students of St. Francis College of Education, Hohoe to improve on their conceptual knowledge of linear inequalities in one variable using the beam balance model. The entire DBE ONE „A‟ students represented the population of the study. Data was gathered through instruments such as test in the form of pre-test and post-test. Due to the large size of the population a total of 40 students which represented 20% of the 200 DBE ONE �...
Malaria and HIV co-infected mothers have an increased risk of poor birth outcome, spontaneous abortion, malaria infection and early progression of HIV to AIDS. This study examines the impact of HIV and malaria on the levels of cytokines in peripheral blood from mothers and their new borns. 149 pregnant mothers and 30 babies born to 63 HIV infected mothers were engaged in longitudinal study for 18 months in the endemic area of Saki and Ibadan. Blood samples collected from mothers and ba...
ABSTRACT This study was set out to examine the barriers to ICT integration into Mathematics teaching and learning in selected Senior High Schools in the Central Region of Ghana. Specifically, the study aimed to examine the effects of internal barriers (constructive teaching beliefs, teaching experience, attitudes toward computer and technology competence) and external barriers (access to technology use, level of training in the use of technology, time adequacy, as well as, the culture of the ...
ABSTRACT Magnetic Resonance Imaging (MRI) of the brain has seen a rising clinical request during diagnosis. The ohmic heating of tissue results in rising human temperature during MRI. This may be as a result of the unintentional heating which seems to be an under-appreciated risk especially of high-field-strength MRI. This study modelled Penne‘s bio-heat equation and used Matlab programming language to predict in-vivo power deposition in brain tissues during ...
ABSTRACT Background: Undetected hearing loss in neonates and children compromises optimal speech and language development and personal achievement. Auditory brainstem response (ABR) test consists of eliciting and recording waveforms generated within the auditory nerve region to the brainstem. These waveforms are compared with normative data to determine normal and abnormal responses. The use of ABR in identifying, and managing infants with congenital hearing impairment is crucial to their aca...
ABSTRACT Choice of university education in Ghana is a competitive exercise for senior High School students. Choosing it requires consideration of various factors. The motivation for the study is to measure high school students’ perception of the University of Cape Coast. To this end, the study focuses on various factors. The objective of the study therefore is to determine the latent factors that are considered by the...
ABSTRACT The study sought to investigate stakeholders’ satisfaction of the Computerized School Selection and Placement system (CSSPS), with regard to information quality, system quality, service quality, technological issues and IT self-efficacy, prior, during and after the opening of the system as against the manual way of selection and placement in the Mfantseman Municipal in the Central region of Ghana. A sample size of 526 respond...
ABSTRACT Globally, climate change continues to pose a serious threat to ecosystems, food security, water resources, health and economic stability. While these climate change induced effects are well documented, albeit in varying spatial contexts, much of the debate has not gravitated towards evidence of gender differentials in the impact of climate change in recent times, especially among smallholder farmers. Against this backdrop, this study explored gender perspectives on climate change a...
ABSTRACT Land use/land cover dynamics in wetland catchments is poorly understood; even though it is an important indicator of wetland ecological health. The study was aimed at detecting and quantifying Land Use/Land Cover (LULC) changes at the Muni-Pomadze Ramsar site in Ghana. The objective was to produce LULC maps for the area, assess the LULC dynamics during a ten year period, and establish statistical relationship between the major LULC changes and biophysical factors that influence...
ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this background that analysis of the characteristics that differentiate the poor from the non-poor in Ghana cannot be underestimated. Poverty indicators make it possible to analyze the likely determinants and are, therefore, essential for formulating policy interventions that may contribute directly or ...
ABSTRACT Advances in Information and Communication Technologies (ICT’s) are changing the way people share, use, and process information . Overtime, students’ academic performance had been used to determine excellence in teacher teaching. This study was conducted to investigate the relationship between teachers’ICT competency and students’ performance in ICT in East Akim Municipality in the Eastern Region of Ghana. It also sought to find out whether availability of ICT r...
ABSTRACT The iodine status of staff and pupils of Hillcrest Schools, undergraduates of UCC, 2016/2017 academic year and a household in Agona Swedru were determined using Titration Method, Sandell-Kolthoff Method and a Novel Method. Discriminant analysis results showed that the Novel Method correctly classified 77.4% of the original cases. The novel also had a percentage recovery of125% and a Horwitz Ratio of 0.12. Based on these, ...
ABSTRACT The non-differentiable L1-norm penalty in the L1-norm regularized least squares problem poses a major challenge to obtaining an analytic solution. The study thus explores smoothing and non-smoothing approximations that yields differentiable loss functional that ensures a close-form solution in over-determined systems. Three smoothing approximations to the L1-norm penalty have been examined. These include the Quadratic, Sigmoid and Cubic Hermite. Tikhonov regularization is then a...
