This project discusses the influence of genomic structure on phenotypic expression in plants and animals, emphasizing intraspecific variations arising from diverse genomic structures. It highlights historical misinterpretations of structural rearrangements and advocates for comprehensive whole chromosome comparisons. The project focuses on using... Continue Reading

CHAPTER ONE INTRODUCTION Background of the Study Biology as a subject of life and living things needs to taught not just theoretically but practically for it be functional and to lay the base foundation needed for science and technological development. Erickson (2005) noted that for a science teaching and learning to be effective every student... Continue Reading

Abstract Search for alternative materials required for shielding ionizing radiation has being on the increase for some period of time. Lead which is widely used is expensive, therefore researches has to be carried out on other materials. Clay has been suggested but it is not as effective as lead in shielding ionizing radiation. This work therefore... Continue Reading

ABSTRACT Plain abdominal radiographs are commonly requested for acute medical emergencies on patients with non-specific abdominal symptoms and signs. Whether plain abdominal radiography contributes to therapeutic decision making or disposition remains questionable particularly in the case of a negative result, the additional value of plain...

ABSTRACT Mouldiness in stored cocoa beans in Ghana and the production of aflatoxin have been studied. Based on actual weight of discarded beans, mouldy beans have been estimated to constitute 0.13 % and 0.00002 % of marketable beans at the farm ers’ level and the buying agents’ depots respectively in the Tafo District. This is contrasted with... Continue Reading

Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. Exposure to indoor ionizing radiation, like gamma radiation, results in critical health challenges. This work was designed to assess the indoor gamma dose rate level following the renovations of offices of lecturers... Continue Reading
