Abstract The petrochemical industry is a major contributor of industrial air pollutants which are known to have dire consequences on human health and the environment, neccesitating research into their dispersion and transport. The objective of the study, therefore, is to simulate the dispersion and transport of pollutants emitted during the processing of crude oil by the Tema Oil Renery in the Greater Accra region of Ghana using the California Pu (CALPUFF) modeling system. This thesis couples...
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 Data from HD-1 well, offshore Tano Basin was subjected to optical and organic geochemical analysis to reveal the palynostratigraphy, palaeoenvironments and hydrocarbon potential of the said well. Organic geochemical studies of Total Organic Carbon and Rock-Eval pyrolysis analysis as well as the microscopic investigation of the 44 slides of ditch cuttings from a depth of 3370ft – 7290ft shows four (4) types of Palynofacies associations in the HD-1 well based on the sedimentary organ...
ABSTRACT The main objective of this study was to measure the effectiveness of formal institutional support on the ability of smallholder farmers to adapt to climate change, using the Sissala East and West Districts of Ghana as cases. The study was also pursued to find out the challenges institutions faced in providing support while investigating the factors that hindered smallholder farmers from accessing institutional support. In line with these objectives the study combined both qualitative...
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 Environmental degradation and the unsustainable exploitation of non-renewable resources continue to increase to satisfy socio-economic demands which call on a National Development Agenda to make use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools imperative. The use of these tools is to balance environmental and economic sustainability with institutional capacity building, and social cohesion to direct the sustainable mana...

ABSTRACT Some environmental impacts such as pollution and widespread of biodiversity loss can be related to the activities of an organisation supply chain. Manufacturing companies such as breweries, instead of investing in environmentally friendly technologies which can help in the prevention of waste at the source, generate large amounts of unnecessary emissions and wastes. The Accra Brewery Limited (ABL) uses a lot of raw materials; it is energy-intensive and generates a lot of waste and e...
ABSTRACT This study was undertaken in three phases to identify (phase 1), screen (phase 11) and evaluate (phase 111) plants for their phytoremediation potential. In Phase 1, 15 plant species made up of grasses and legumes namely: Paspalum. vaginatum, Cynodon.dactylon, Pueraria. phaseoloides, Centrosema. pubescens, Panicum. maximum, Schrankia. leptocarpa, Eclipta. alba (Linn.), Cyperus. haspen (Linn.), Melastromastrum. capitatum, Acreceras. zizanoides Dandy, Pteridum aquilinum (Linn), Ludwigia...
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...
ABSTRACT Anopheles gambiae s.s. larval habitats are important determinants of adult distribution and abundance, which also determines the geographical pattern of malaria disease. Information on their habitat characteristics can contribute greatly to better planning of its control strategies through environmental management. To identify the environmental parameters, which influence the distribution of An. gambiae s.s. larval populations in urban Accra, Ghana, 30 habitats with An. gambiae s.I....
ABSTRACT Malaria is a threat to more than 40% of the world's population accounting for more than 300 million acute cases and between 1.1 and 2.7 million deaths annually. Over 90% of the malaria cases are in sub-Saharan Africa, constituting 10% of the total disease burden. Currently, activities support the extensive use of insecticide-treated materials for malaria control. However, these efforts are threatened by the evolution of resistance in the main malaria vectors, Anopheles gambiae s.l. ...
Abstract Cowpea is an important food crop in Africa but suffers from a variety of insect pests. Among those is Megalurothrips sjostedti (Trybom), a major pest that is not successfully controlled by its local natural enemies. One of them, Ceranisus menes (Walker), a cosmopolitan endoparasitoid of thrips larvae provides efficient control of thrips populations in Southeast Asia. This has necessitated a study of this insect which involves a comparison of the biology of the African and Asian popu...
