ABSTRACT Honey is a universal product with a wide usage throughout the life spectrum. It is a substitute for sugar for many people, an energy booster, helps maintain the blood sugar level and research has shown that it has the potential for cancer prevention. The high sugar concentration of honey and its low pH gives honey antimicrobial properties and makes it difficult for microorganisms to grow. However, research has provided evidence of the presence of microbes in honey. The microbes are i...
ABSTRACT The main objective of this study was to compare the similarities and differences in MRbased and pseudo CT µ-map generation in PET/MR and radiotherapy respectively. The study sought to look at ways attenuation correction could be done on PET hybrid imaging systems and compare them in various ways so as to improve treatment and patient care. The methodology involved patient selection, image processing and generation of both µmaps for PET-attenuation correction and pseudo CT for radio...
ABSTRACT The Lower Anayari catchment (LAC) located in the Upper East Region of Ghana, is part of the transboundary (Ghana and Burkina Faso) Anayari catchment. The other transboundary catchments are Atankwidi and Yarigatanga. These catchments are noted for intense farming activities. The population within Lower Anayari catchment area is estimated to be about 19,445. An estimate of about 80% of the population depends on groundwater for domestic and agricultural purposes. Agriculture has direct ...
ABSTRACT This study has been undertaken to estimate the occupational and public radiation doses due to natural radioactivity at Morupule A Coal-Fired Power Station and its environs. The radiation doses were reconstructed to include 60 year period from 1985 to 2045. Direct gamma ray spectroscopy was used to determine the natural radionuclides Th-232, U-238, and K-40 both qualitatively and quantitatively for fly ash, coal, soil and water (from the fly ash ponds) samples. The average activity co...
ABSTRACT Energy and exergy analyses of the performance of the Westinghouse Advanced Passive 1000-MWe Nuclear Plant (AP1000) was conducted with the primary objectives to identify and quantify the operational locations having the largest energy and exergy losses under normal operating conditions. The energy and exergy losses in the reactor units were determined from formulations of the energy and exergy rate balances based on the Gouy-Stodola theorem. The performance of the overall AP1000 plant...
ABSTRACT Ghana, as most other countries, has a considerable variation in its topography. In an attempt to build cheaper, but yet the safe structures (i.e., roads, apartments, etc.), we are most often times faced with building on hill-sides and in valleys. This then calls for the need to correctly assess the stability of any adjacent slopes. In recent times, due to the extensive need for stability analysis in engineering practice, slope stability analysis programs have been developed. It is no...
ABSTRACT The European Pressurized Water Reactor (EPR) and Hualong One Pressurized Water Reactor (HPR) are two of the reactors under consideration by the Ghana Nuclear Power Programme. Radiotoxicity analysis of Spent Nuclear Fuel (SNF) assembly was carried out with these commercial Pressurized Water Reactor (PWR) nuclear power technology as case study. Burnup depletion calculation for the Uranium Oxide (UOX) fuel of these reactor technologies was simulated. Monte Carlo Neutron Particle Extende...
ABSTRACT A LabVIEW simulator of thermal-hydraulics has been developed to demonstrate the temperature profile of coolant flow in the reactor core during normal operation. The simulator could equally be used for any transient behaviour of the reactor. Heat generation, transfer and the associated temperature profile in the fuel-channel elements viz: the coolant, cladding and fuel were studied and the corresponding analytical temperature equations in the axial and radial directions for the coola...
The prevalence of counterfeit drugs is seen as a problem faced in both developed and developing countries where Ghana is not an exception. Antibiotics are amongst the most counterfeit drugs in developing countries. What is less understood is that there are inadequate and ineffective quality control procedures in monitoring of drugs manufactured and imported into the country. This research work is aimed at contributing towards the development of routine analytical procedures that will fa...
ABSTRACT Supercritical Cooled-Water Reactor (SCWR) which is planned to be deployed by 2030 derives its concept from Light Water Reactors (Boiling Water Reactor (BWR), Pressurized Water Reactor (PWR) and Fossil Fired Coal Plant but with a simpler design. Due to the strong variations of density at supercritical pressure, the SCWR is likely to inherit some of the issues related to the LWR’s in terms of heat transfer (e.g. thermal crisis). This research was undertaken in order to better underst...
ABSTRACT The present study was conducted to characterised and assess heavy metal contamination in food through milling process and their health implications. Grinding plate made from Ghana, India and Nigeria purchased from the Ghanaian open market were used for this work. Maize from the same farm was milled into flour using the three grinding plates inserted into three different corn milling machines operating on commercial bases. The first grinding was done immediately after the insertion o...
ABSTRACT Groundwater resource development in Ghana contributes substantially to the socioeconomic development of Ghana. Utilization of water for domestic, irrigation and industrial purposes for about 80% of the rural – urban population in the Kwabenya Community within the Ga East Municipality are primarily dependent on existing groundwater resources. However, groundwater potential is under serious threat and run a high risk of pollution by agrochemicals, municipal, industrial, and domestic ...
ABSTRACT This research work was aimed at assessing the quality management system and radiation protection of patients of four mammography facilities in Ethiopia. A questionnaire was designed to collect data to assess the status of the quality management systems at the facilities. Quality control measurements were done to verify whether the mammography machines were performing self- consistently compatible with National and International standards. The status of patient protection was evaluate...
ABSTRACT The research was conducted to assess the levels of contamination of heavy metal in topsoil at auto-workshops in Accra, to determine the anthropogenic and crustal contributions and the human health risk associated with them. Soil samples collected from four selected auto-workshops were analysed using Atomic Absorption Spectrometer. Eleven (11) elements: Co, Fe, Cu, Mn, Cr, As, Hg, Zn, Pb, Ni and Cd were identified in each sample collected from the auto-workshops. Pollution indices; co...
ABSTRACT In this study a total of 28 water and soil samples were analysed by High Purity Germanium (HPGe) detector for 222Rn (Radon), 220Rn (Thoron) and other natural radionuclides (226Ra, 232Th plus 40K) activity concentrations. The data generated was then used to assess radiological hazards posed to the public. The radon (Rn-222) concentration in the surface water varied from 0.015 to 1.701 Bq/L with a mean value of 0.913 ± 0.605 Bq/L against the global average of 11 Bq/L and thoron (Rn-22...
