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 Lactic Acid Bacteria (LAB) are the most widespread of organisms responsible for food fermentation and have been applied as commercial starter cultures in many food industries. A study was conducted to develop a starter culture for the fermentation of millet into Fura and to extend the shelf life of Fura by gamma radiation. The isolation,... 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

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

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
