ABSTRACT Background to the study Radon is a globally present and known radioactive gas with its ability to cause lung cancer as its major health implication. Ghana currently lacks national policies on radon gas and substantive radon vulnerability map largely due to lack of adequate baseline radon concentration data for the entire country. This thesis thus seeks to provide baseline radon data for the South-Dayi District, the effective dose assessment due to inhalation of the measured in-door c...
ABSTRACT The n-butanol fraction (nBF) of Desmodium adscendens , a plant used for the management of asthma, is' an inhibitor of NADFH-dependent cytochrcme P-450 (CYP) reactions. Its mechanism of action as an inhibitor is hcwever not kncwn. In this stud/, flavoprotein reductase activity, spectral changes associated with binding and spectral prcperties of reduced cytochrcme c and CYP were used to investigate the mode of inhibition. nBF reduced cytochrome c but not CYP directly. In the presence o...
A B S T R A C T Four experiments were undertaken to evaluate the e f fe c t of various treatment conditions on the nu tr itiv e value of urea-ammoniated r ic e straw. Experiment 1 was carried out to determine the optimum condtions necessary fo r ammoniating r ic e straw with urea. The factors investigated included urea concentration (3 .5 , 4.0, 6.5 and 8.0% W/w), treatment period (7, 14 and 21 days) and moisture le v e l (40, 50 and 60%), in a 4 x 3 x 3 fa c to r ia l experiment. Samples wer...
ABSTRACT Background: Breast cancer is the most commonly diagnosed malignancy and an important cause of cancer death among females worldwide, it accounted for 25% (1.67 million) of the total new cancer cases diagnosed and the fifth cause of overall cancer deaths. Approximately half the breast cancer cases and 14.3% (324,000) of the deaths from cancer are attributed to breast cancer and are expected to occur in poor developing countries of the world (Ferlay et al., 2015). The main aim of this s...
ABSTRACT A challenge confronting the study of punishment in contemporary society is the justification of the institution concerned with the deliberate infliction of suffering on an offender. Most of these justifications have been anchored on either of two competing theories, namely the utilitarian and retributivist theories of punishment to the neglect of integrative notion of punishment found among the Yoruba. However, these theories fail to account for some elements necessary for an adequa...
ABSTRACT This is a phenomenological study which explores how rural women conceptualise intimate partner violence (IPV) from their own perspectives. The study also examines the lived experiences and resilience of women who have been victimised in their intimate relationships. Two theoretical strands form the framework of this study and they are, the Integrative Feminist Model and the Strengths Perspective. The research combines two qualitative designs namely, in-depth interviews, and communi...
Abstract Background Vaccination undoubtedly remains one of the most cost-effective ways of decreasing child morbidity and mortality globally. Ga East Municipality is one of the districts with a low operational vaccination coverage in the Greater Accra Region. The municipality in 2015 recorded 71%, 78% and 74% as its BCG, Penta3 and Measles 2 vaccination coverage. Accumulation of unvaccinated population lowers herd immunity thereby lead to disease outbreaks. This study sought the factors assoc...
J B B S I R A C I . Reports on the number of isolates and yeast species obtained from palmwine samples have differed very widely. One factor that probably accounts for this is the method of phenotypic discontinuity which has exclusively been employed in palmwine yeast speciation. The phenotypic features used mainly for this kind of speciation have been shown to be unstable. Consequently it was decided to employ the more consistent; and reliable method of Restriction Fragment Length Polymorphi...
ABSTRACT Experiments were carried out to examine the ease of establishment of some native browse species through both seed and stem cuttings, the forage production from these browse species and the nutritive quality of the forage produced as livestock feed. Five experiments were therefore conducted to address the problem. Experiment I: The objective of this experiment was to test in vitro techniques for breaking the dormancy of the seed of some native browse plants. Germination tests were per...
ABSTRACT The banking industry in Ghana over the years has experienced significant growth owing to reforms and deregulation that characterised the sector. This however has changed and the sector is beset with slow growth as a result of fierce competition of keeping existing customers and attracting new ones and this has shifted the focus of marketing into a relationship paradigm. Despite the challenges in the banking sector, customers continue to seek value and this however, makes it important...
ABSTRACT Since Plato, political philosophy has been regarded as man's attempt to prescribe the ideal solution to the problems of governance, in order to bring the ideal state into being. In post-colonial Africa, several post-independence African leaders, prominent among them, Kwame Nkrumah, attempted theoretical constructions of this ideal state. Nkrumah particularly thought that the three factors that could bring about the ideal state in colonial Africa were: the realisation of political ind...
SUMMARY Several Plasmodium spp. antigens have been found to be associated with protection against malaria and a few have been tested in the field in human volunteers. However, these efforts have achieved limited success, and as a result the search for additional more potent malaria vaccine components continues. The work reported in this thesis was executed with the objective of determining the suitability of three peptides obtained from the merozoite surface antigen, MSA-2, as putative sub-u...
ABSTRACT Two field experiments were conducted at the Multipurpose Crop Nursery of the University of Education, Winneba, Mampong-Ashanti campus during the minor and major rainy seasons from September, 2011 to January, 2012 and April to August, 2012 respectively to verify the yield and storability of sweetpotato roots as influenced by chicken manure and inorganic fertilzer in the forest transitional agro-ecological zone of Ghana.. In both cropping seasons sweetpotato root tubers were stored fo...
ABSTRACT Post implant dosimetry has become the gold standard for prostate implant evaluation. The goal of this research was to compare the dosimetry of intraoperative real-time ultrasound plan to CT postimplant plan in permanent prostate seed implant brachytherapy. A retrospective study of 20 patients treated with 125 I prostate seeds implant were performed. All plans were created using VariSeed 8.0 planning system. Intraoperative real-time ultrasound images were acquired using 0.5 cm slice ...
ABSTRACT This study probes the perspective of Wojtyla’s sexual ethics regarding his views on love and responsibility and his synthesis on the ends of marriage and the morality of the use of contraception in marriage. “Love and Responsibility” is the title and the theme of his book on sexual ethics which reflects his own brand of moral philosophy. Karol Wojtyla argues against the use of contraceptives for married couples. His view is that contraceptive sexual intercourse is reductive, do...
