An Assessment of Environmental and Economic Effects of Tourism in Communities Around Wli Waterfalls and Lake Bosomtwi in Ghana

ABSTRACT The study sought to assess the effects of tourism on the environment and economic activities in the communities around Lake Bosomtwi and Wli Waterfalls. Methodology used included analysis of water samples from the Lake and Waterfall. Satellite images covering the period between 1990 and 2010 of land use around the Lake Bosomtwi and Wli Waterfalls were also analyzed to see if tourism is affecting vegetative cover around the Lake Bosomtwi and Wli Waterfalls. In addition, a social surve...

Evaluation Of The Potential Of Adding Tiger Nut Milk And Soy Milk Into Cheese Making.

ABSTRACT The purpose of this study was to evaluate the potential of incorporating tiger nut milk and soy milk in cheese making. In all 16 different formulations were prepared from tiger nut milk, soy milk and cow milk. Texture analysis, colour evaluation and chemical analysis were carried out on all the 16 cheese samples. Two parameters were measured (firmness and fracturability). Protein, fat, moisture content and pH were determined with respect to the chemical analysis. For the colour evalu...

Comparison Of Methods Of µ-Map Generation: Mr-Based Method In Pet/Mr Imaging Versus Pseudo-Ct Method In Radiotherapy Dose Planning

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...

Hydrogeochemical And Isotopic Studies Of Ground And Surface Waters In The Lower Anayari Catchment Area, Upper East Region Of Ghana

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 ...

Numerical Simulation of Dispersion of Emissions from Tema Oil Re nery in Ghana

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...

Dose Assessment Of Natural Radioactivity In Fly Ash And Environmental Materials From Morupule A Coal-Fired Power Station In Botswana

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...

Palynology, Palynofacies And Hydrocarbon Potential Of Cretaceous Sediments In The Offshore Tano Basin

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...

The Role Of Institutional Support In Climate Change Adaptation Amongst Smallholder Farmers In The Sissala East And West Districts Of Ghana

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...

Energy and Exergy Based Performance Analysis of Westinghouse AP1000 Nuclear Power Plant

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...

Numerical Modeling and Simulation of the Stability of Earth Slopes

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...

Investigative Study Of Radiotoxicity Of Spent Nuclear Fuel Assembly Of Some Commercial Nuclear Power Plants Case Study: European Pressurized Water Reactor And Hualong One Pressurized Water Re

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...

Strategic Environmental Assessment (Sea) As A Sustainability Tool For Policy And Decision Making: A Case Of The Atiwa Forest Management In The Abuakwa South Municipality Of Eastern Region Of

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...

The Role of Green Procurement in Sustainable Waste Management in Ghana: A Case Study of Accra Brewery Limited

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...
