A BSTRA CT The consumer’s perception of quality has been identified as the benchmark for quality around which all processing and marketing activities must revolve in order to achieve maximum profitability in industry, hi spite of this awareness, the consumer’s perception o f quality is yet to be fully understood to enable manufacturers translate consumer needs and expectations into business success. A number o f factors account for this failure including the complexity, subjectivity and m...
ABSTRACT The aim of this study was in two to investigate; firstly, (i) location of radiosensitive organs in the interior of four (4) paediatric anthropomorphic phantoms, and, secondly, (ii) effectiveness of single and double bismuth thyroid shields, distance between shield and phantom surface, during paediatric multi-detector computed tomography (MDCT) using fixed tube current (FTC) and automatic exposure control (AEC) on dose reduction and image quality. Four (4) paediatric anthropomorphic p...
ABSTRACT Solar dryers have become important components for the delivery of dried agricultural products of high quality. They generally are designed to maximize the production of a heating system based on solar radiation. This study involved the design, building and testing of a control system to allow the monitoring of temperature, solar radiations and control of humidity in a Photovoltaic (PV)- Greenhouse Solar Dryer (PVGSD). This was accomplished by assembling a solar charge controller, thr...
ABSTRACT The study assessed the necessary means to promote ecotourism in the Suhum Kraboah Coaltar District owing to the potential ecotourism attractions the district abounds with. Forty respondents were purposively selected in the district for in-depth interview, using an interview guide. Data collected were analysed qualitatively. Findings of the study generally indicated that respondents are willing to participate in the ecotourism venture since they believe it will aid them, or especiall...
ABSTRACT This work presents the effects of metakaolin as a supplementary cementitious material in mortars for construction applications. Kaolin from Teleku Bokazo was calcined at 650oC and partially used to replace Portland limestone cement to produce mortars and paste. The metakaolin was successfully used in a cement paste and its effect observed in the different cement replacements proportions. The replacements ranged from 10% - 35% by mass and characterised after 3, 7, 14 and 28 days of cu...
ABSTRACT Livestock production is one of the farming systems and has a great impact on food and economic security in most developing countries. Animal African trypanosomiasis is a major limitation to livestock production in Africa, particularly cattle production. The disease is caused by Trypanosoma spp., a broad range of protozoan parasites of wild and domestic animals through cyclical and mechanical transmission. Cross-sectional studies conducted in Ghana reveal the common species of trypano...
ABSTRACT Rating undergraduate programs of higher educational institutions is a common, albeit argumentative practice. However, prospective students, parents and faculty members deserve the opportunity to compare the relative strengths of the programs and the institutions when making educational and (or) personal decisions. The main objective of this research is to evaluate statistics programs indicators of the tertiary institutions. The researcher actually wants to know which of the indicator...
Introduction Bacteria are essential components of all ecosystems. They inhabit soil, water, air and even travel in space (Afshinnekoo et al., 2015; Osman et al., 2008). Bacteria also survive on inanimate objects such as fomites either transiently or for long periods (Boone and Gerba, 2007; Miller and Diep, 2008). Some bacteria that live in contact with or infect animals, have been implicated in zoonotic infections, which can be a health risk for humans (Cantas and Suer, 2014) and can modulate...
ABSTRACT This study investigated whether the use of the balance model in the teaching and learning of linear equations can improve students‟ conceptual understanding in the principles of solving linear equations in one variable. The data was gathered using tests. A pre-test conducted on thirty (30) Form two pupils of Buasi Roman Catholic Junior High School and an analysis of the interviews enabled the development and the use of the balance model in the teaching of linear equations ...
The total world population o£ about 5,128million in 1988 has increased rapidly to 5.508 million by 1993 with an annual natural growth rate o£ 1.6 percent (World Population Data Sheet. 1988 and 1993). Ironically, about 76.3 per cent (4,276 .111ion) o£ this large world population is £found in the less developed world where resources are less abundant. It is also in this part o£ the world where annual growth rates are high. For example Ghana's total populat10n o£ 14.4 Mil110n in 1988 has i...
ABSTRACT Functional diversity, an important component of biodiversity, has in recent years engaged global attention. This is in great part due to the mechanistic understanding achieved from functional diversity studies in the face of accelerated global biodiversity changes ascribed primarily to anthropogenic drivers. The exigency of the situation has stimulated biodiversity-ecosystem functions (B-EF) studies to elucidate ecosystem processes and services that are at threat notably in the marin...
ABSTRACT In the present study, the stem of Dichapetalum crassifolium was investigated for its phytochemical constituents and their biological properties. The petroleum ether extract yielded friedelan-3-one, friedelan-3β-ol and a mixture of friedelan-3-one and friedelan-3β-ol. The ethyl acetate extract yielded pomolic acid, dichapetalin M and maslinic acid as well as the friedelins and a mixture of β-sitosterol and stigmasterol. No solid was isolated from the methanol extract. These compoun...
ABSTRACT Globalization and the spread of export processing zones (EPZs) have resulted in the global drift of women into paid employment in this sector with marked implications for their empowerment across the world. Although Ghana has joined the tidal wave of establishing EPZs, the conditions under which women work in this sector and its implications on their empowerment are not well understood. This study was therefore conducted to assess the working conditions in Ghana’s EPZ and its influ...
ABSTRACT The Akwapim Fault zone is one of the two major fault zones in the southeastern part of Ghana. Its junction with the Coastal Boundary Fault happens to be epicenter for most of the earthquakes that occur in Ghana. The earliest work done in this region was by the Gold Coast Geological Survey on a regional scale in mapping the area to determine the geological structures. With most of geological deformational features being inferred, it is prudent to carry out more research to identify mo...
ABSTRACT The current commercial production of biodiesel is via transesterification reaction, catalysed by homogeneous or heterogeneous catalysts. The most commonly used catalyst in biodiesel production is the homogeneous alkaline catalysts such as NaOH, KOH, CH3ONa and CH3OK. The choice of these catalysts is based on their higher kinetic reaction rates. However because of high cost of refined feedstocks and difficulties associated with the use of homogeneous alkaline catalysts to transesterif...
