Establishing Clinical Normative Data For Neurodiagnostic Auditory Brainstem Response Testing For The Korle-Bu Teaching Hospital

ABSTRACT Background: Auditory Brainstem Response are series of scalp recorded electrical potentials of neural activity generated within the auditory nerve, nuclei and tracts of the lower brainstem during the first 10 ms after a click or tone pip stimulus presentation. Aim: To develop normative data for the Intelligent Hearing Systems Smart EP systems (IHS) at the Korle-Bu Teaching Hospital’s Hearing Assessment Center (KBTHHAC). Objective: The study was to discover the relationship between t...

Design And Fabrication Of A Sustainable Construction Brick

ABSTRACT The urgent need for affordable housing is driving the research for cheap and sustainable building materials. The nuisance caused by cocoa pod husks, which is an agro waste, could be curbed by the incorporation of potash derived from its ash into brick batch mix. These potash incorporated bricks tend to allow sintering at lower temperatures thus reducing production cost and hence making them cheaper. In this project, the SiO2 – Al2O3 – K2O ternary phase diagram was used to design ...

Bayesian Hierarchical Model With Classification And Regression Tree In Predicting Loan Default

ABSTRACT Bayesian modelling as well as decision tree methods are some of the efficacious classification methods in credit scoring applications. Application of these methods to credit scoring provides several advantages, which are highlighted in the literature. In this research, a Bayesian hierarchical model using the latent variable approach coupled with the classification and regression tree ‘CART’ approach is applied to classify customers who applied for loans into potential defaulters ...

Some Approaches To Modelling Need-Based Finanacial Aid To Needy Students In The University Of Ghana

ABSTRACT It was asserted that University and university systems around the world are faced with rapid growing demand and decreasing or static government investment (Marcucci and Johnstone, 2010). In response to this assertion, many countries introduced cost-sharing in order to preserve the quality of higher education. In order not to deny academically talented young people from poor families from accessing higher education, governments and individual institutions started offering financial as...

Molecular Diversity And Technological Properties Of Predominant Microorganisms Associated With The Processing Of Millet Into Fura, A Fermented Food In Ghana

ABSTRACT Fura is a millet-based spontaneously fermented dumpling produced and consumed in parts of West Africa, particularly Nigeria, Burkina Faso and Ghana. From eight (8) traditional fura production sites in northern Ghana, lactic acid bacteria (LAB) and yeasts were isolated, characterized and identified using genotypic methods. These included (GTG)5-based rep-PCR fingerprinting, sequencing of the 16S rRNA gene, multiplex PCR by means of recA gene sequence comparison and sequencing of D1/D2...

Lighting Activity Over Legon And Its Application to Rainfall Estimation

ABSTRACT  Lightning is an important component in the global electric circuit of the earth. It is a leading cause of outages in electric power and telecommunication systems, of forest fires and of delays in aircraft missions. A lightning sensor operating at a radio frequency of300 kHz was constructed ~d used to study the occurrence of lightning in and around the University of Ghana campus during thunderstonns. Rainfall figures during each thunderstonn were also recorded. Data was collected ov...

Prevalence of Hearing Loss Among Sickle Cell Patients at The Korle-Bu Teaching Hospital

ABSTRACT Background: Sickle Cell Disease (SCD) is one of the commonest blood and genetic disorders in the world. It results when abnormal haemoglobin (Hb S, Hb C, Hb β-thalassemia) is found either in the homozygous or heterozygote state. Sickle cell disease causes painful vascular occlusion crisis, anoxia and ischaemia which sometimes lead to tissue or organ damage including the auditory system especially the blood rich cochlear. Damage to the auditory system eventually causes hearing loss....

Thin Layer Chromatographic Studies on Some Herbicides in Two Soil Ecosystems

ABSTRACT Depletion rates of three triazine herbicides, atrazine, simazine and ametrine and two urea based herbicides, diuron and metobromuron, under laboratory conditions have been investigated in soil samples collected from GAEC, a coastal savannah soil, and KNUST, a forest zone soil. Two hundred grammes of the soil samples were treated with herbicides standard solution to generate herbicide-soil the concentration of 10 pg/g and incubated at room temperature for 12 weeks. TLC methodology wa...

Eating Out: Nutrition And Health Implications

ABSTRACT  Background: Eating out (EO) has been identified as a significant driver to the poor quality of diet due to the high fat, sodium and energy content of meals which have a negative consequence on nutritional health, resulting in overweight/obesity and related non-communicable diseases. The study sought to assess EO lifestyle and associated factors; assess the nutrient content of some selected meals from fast-food restaurants (FFRs) in Accra; and associations of EO lifestyle with selec...

Identification and field evaluation of bioactive natural products for use in schistosome host snail traps

ABSTRACT The behavioural responses o f two schistosom e host snails (Bitlinus Iruncattts and Biomphalaria pfeifferi) to tw enty-six naturally occurring (crude and sem i-processed) products weic measured in diffusion olfactom eters. 15 out o f these 26 m aterials (i.e. 57% ) were found to act as statistically significant attractants for adult 13. pfeifferi w hile only 5 (19%) o f the lest materials clicited statistically significant responses from the adults o f B. truncatus. The juveniles oil...

The Effects Of Local Antimalarial Drugs On Plasmodium Falciparum Gametocytes

ABSTRACT The gametocytocidal effect of antimalarial drugs has become important in malaria research owing to the global quest to eradicate the disease. In Ghana and most parts of Africa, people still depend on herbal medications despite advances in western medicine. However, these drugs lack the necessary scientific assessment. The IC50s of 10 known herbal antimalarial drugs on the Ghanaian market were determined. The development of sexual stages of the Plasmodium falciparum was monitored and ...

Contribution Of Value Addition In Agriculture To Development: Case Of The Oil Palm Industry In Kwaebibirem District, Ghana

ABSTRACT This study examined the contribution of value addition in agriculture to socio-economic development with reference to the oil palm industry in Kwaebibirem District. The specific objectives addressed in this study were to: determine the character of the activities that generate value in the oil palm industry; find how the process of value addition contributes to development, especially in terms of employment and income; and analyse the wider policy implications for agricultural develo...

Some Inequalities for the p-Digamma Function

Abstract Some inequalities involving the p-digamma function are presented. These results are the p-analogues of some recent results.

Survival Analysis Of Average Time To Justice Delivery In Upper East And Upper West Regions Of Ghana.

ABSTRACT The right to a fair hearing within a reasonable time by a court when charged with a criminal offence and to a speedy and public trial in all criminal prosecutions are some of the basic rights guaranteed by the 1992 constitution of the Republic of Ghana. In this study, survival analysis was used to determine the average time to justice delivery for the upper east and west regions of Ghana both first collectively and as individual entities. Type of cases that last longer in courts and...

An Optimal Energy Mix Investment For Ghana

ABSTRACT This study aimed at finding a minimum cost of investment in Renewable Energy (RE) sources, specifically in Hydro, Wind, Solar and Biomass that will meet projected demand levels in specific time periods in the future and ensure a modest (10%), (20%) or an ambitious (30%) incorporation of these renewable energy sources. To do this, a relevant optimization model was formulated and discussed. The Levelized Cost of Energy (LCOE) model adopted for the purpose was also discussed in detail....
