Municipal solid waste landfill is an important part of the urban infrastructure that ensures the protection of environment and human health. Landfill selection problem for municipal solid waste involves many factors, criteria and regulations. The aim of this study is to access suitable site for an engineered solid waste landfill, ·with specific objectives of site determination based on UNEP criteria and carrying out both geophysical and geotechnical evaluation of the site. The study are...
ABSTRACT Malawi became an IAEA member state in 2006 and developed the Atomic Energy Act and Regulations in 2011 and 2012 respectively. However, regulatory authority and personnel monitoring services have not yet been established. As such, hospitals operating radiological services in Malawi do not have personnel monitoring programme. This study aimed at developing the personnel radiation monitoring program for three hospitals in Malawi namely; Kamuzu Central Hospital, Bwaila Hospital, and Mten...
ABSTRACT The production of cassava (Manihot esculenta Crantz) under rain-fed conditions at the Kwabenya-Atomic area in the coastal savannah environment is constrained by low and erratic rainfall events. Improving cassava production in the area requires the use of cassava varieties which are efficient in the use of limited soil moisture. The objective of the study was to evaluate the response of two early maturing cassava varieties to three (3) planting densities to TDM, RY, and WUE. The actua...
ABSTRACT Cabbage is a popular vegetable grown in Ghana and serves as an important source of livelihood for small-scale farmers, especially in urban areas. However, its cultivation encounters several constraints such as attack by insect pests. A key insect pest is aphid that cause significant to the crops as they serve as vectors of plant diseases. Farmers thus resort to indiscriminate use of insecticides to reduce the damage caused by insect pests. However, insecticides are associated with ad...
ABSTRACT The main objective of this work is to assess the integrity of structural shielding to validate the protection of the staff and the public for two selected general radiography and CT facilities. The assessment for general radiography was based on 729 examinations for facility A and 706 examinations for facility B. For computed tomography (CT) rooms, a total of 293 body and 190 head procedures were used for facility A, and 195 body and 160 head procedures for facility B. For general ra...
ABSTRACT Bedbugs are blood-sucking insects of the order Hemiptera and family Cimicidae that derive nutrition from vertebrates, including humans, their feeding is allied to the transmitting several fungal, bacterial and viral infections. A rise in international travels and emergence of insecticide resistant bedbugs within the past decade has led to renewed interest in studying these insects. Anecdotally, bedbugs exist in homes, boarding houses, hotels and other human dwellings in Ghana but hav...
ABSTRACT Tephritid fruit flies are a major threat to the horticultural industry in sub-Saharan Africa owing to the heavy losses they cause to fruit and vegetable crops, and the resultant quarantine restrictions. Addressing the fruit fly menace in Ghana requires effective stakeholder training along the fruit value chain, coupled with adequate research information on management strategies. Baseline studies were conducted in northern Ghana to determine the priority management training needs of f...
ABSTRACT Counterfeit and substandard pharmaceutical drugs are chiefly rampant in developing countries due to inadequate analytical facilities and lack of regulatory oversight. The production of counterfeit or substandard drugs is broadly problematic. Underestimating it therefore leads to morbidity, mortality, drug resistance, introduction of toxic substances into the body and loss of confidence in health care systems. Medical drugs that are often counterfeited range from antimalarial drugs to...
ABSTRACT Twenty (20) accessions of hot pepper (Capsicum spp L.) were collected from eight geographical regions of Ghana for genetic diversity studies. The objective was to assess genetic relationship among them using phenotypic and molecular traits and to evaluate their elemental composition. A replicated field experiment was conducted to assess their genetic diversity based on 13 quantative traits and 22 qualitative traits using the IBPGR descriptor list for Capsicum. Confirmation of their i...
ABSTRACT Operational power of a nuclear reactor core is limited by thermal considerations. In principle, the allowable core power is restricted by the rate at which the heat can be transferred from the fuel to the coolant. Unlike in conventional combustion facilities where the heat is released in gas-flows, heat in the nuclear reactor core is mainly released in the structural material. If not properly removed the structural materials inevitably melt causing release of radioactive material. ST...
ABSTRACT The Paboase deposit located in the Chirano gold district is hosted in Paleoproterozoic rocks within the Sefwi-Bibiani volcanic belt of the Birimian, which has been regionally metamorphosed to greenschist facies. Gold mineralization at Paboase is largely hosted by albite-pyrite-carbonate altered mafic and porphyry intrusive rocks rather than Birimian sedimentary rocks and graphitic shear zones which are well known style of mineralization in southwest Ghana. Multi-element geochemistry ...
ABSTRACT Sweet potato (Ipomoea batatas Lam.) is a staple food crop for a large proportion of the population in sub-Saharan Africa. One important factor limiting its production and utilisation is infestation by weevils belonging to the genus Cylas, commonly known as sweetpotato weevils. The use of host plant resistance is an essential component for the integrated pest management of sweetpotato weevils. In this study, the susceptibility of some Ghanaian sweet potato varieties to infestations by...
ABSTRACT Organic nutrient sources such as compost could be used to improve the low fertility of tropical soils as it has the potential to enhance soil physical, chemical and biological properties and improve growth, yield and quality of crops. Pot and field experiments were conducted to investigate the effect of compost on growth, yield and nutritional quality of okra, Abelmoschus esculentus (L.) Moench. The pot experiment was done using the Completely Randomized design while field trial was ...
ABSTRACT Gas–liquid bubbly flows are commonly encountered in many industrial processes. In many cases, the evolution of bubble size distribution is a crucial factor governing the momentum, heat and mass transfer between phases within the system. In this thesis, numerical investigation of gas-liquid bubbly flows is achieved by coupling a population balance model with the three-dimensional, two-fluid model. With the aim of evaluating the capabilities of the population balance model, a model v...
