ABSTRACT Flood is most predominant natural disaster in the world, affecting most cities in Africa especially during rainy seasons. Only an average of 100 floods per decade used to occur. However, since middle of 20th century, flood cases have increased to more than 2,800 per decade. In Sub-Saharan African countries, efforts at managing flood disasters are mainly reactive approaches such as provision of relief to affected people. Reasons are that there is low level of technology for adaptation...
ABSTRACT Set-up errors are the inherent features of the radiation treatment process. Coverage of target volume is a direct function of set-up margins, which should be optimized to prevent unintended irradiation of adjacent normal tissues. The aim of this study was to evaluate three dimensional set-up errors and propose optimum margins for target volume coverage in prostate cancer radiotherapy. 1620 Portal images were obtained for an average of 30 fractions per patient for 54 prostate cancer p...
ln this work, the researchers consider the concept of Information Security by the application of firewall and encryption techniques. Also, the problem of explicitly exposing infonnation in transit is discussed. We developed several algorithms. Among the algorithms are those of random sequence and non-arithmetic sequence using modified generators for the problem to secure information that may pass through intermediate computers linked in the Internet. Some of these algorithms employ modif...
ABSTRACT Fish from artisanal sources constitute the most important animal protein in the Ghanaian diet. The availability and safety of fish on the Ghanaian market is however now unpredictable owing to potential rapid microbial growth which results from high ambient temperatures and poor handling along the artisanal value chains. Little is known about the artisanal fish value chains as well as the food safety knowledge and handling practices of key stakeholders involved. This study aimed at ma...
The recently developed Adjusted Ridge Estimator (ARE) for handling multicollinearity problem in Linear Regression model does not require the use of the biasing or ridge parameter, K, unlike the Ridge Regression Estimators (RRE) rather it requires a diagonalization of the correlation vector of the explanatory variables and the dependent variable being raised to a power of half In this research, the effects of other powers on the Adjusted Ridge Regression Estimator were investigated and a ...
ABSTRACT Burkina is a milk/millet product which has suddenly become popular in Ghana in the last few years. The product is thought to have originated from Burkina Faso but Burkina is unknown in that country. Rather Degue, a Fulani fermented milk product containing millet is well known in West African Sahelian countries including Burkina Faso. This work was carried out to compare the burkina and Degue processes, and develop a starter culture for the production of Burkina/ Degue in Ghana. A sur...
The purpose of this work is not to present a collection of routines that might appear in a professional software library; rather, the intention is to introduce a method of solving linear algebraic equations using Pascal Programming. This dissertation solves linear algebraic equations by Cramer's rule method using Pascal Programming. The basis for this method of solution was obtained from the knowledge of numerical method, such a method lies within the discipline of numerical analysis.
The whole idea of World Wide Web (WWVV) was born out of the desire that information should be shared. Presently WWW is really information domain. Today, users of the Web can easily access this information by specifying URI addresses, searching, and following links to find other related resources, but, in some cases users are taken to an irrelevant site. Another limitation of WWW is that the information can only be understood and interpreted by human being, it is difficult for machine to...
Fourteen (14) sweet potato (Ipomoea batatas(L.)Lam.) clones, TIS.8441, Ex Igbariam, TIS.86/0356, TIS.86/0306, TIS.2271, TIS.2532.OP.1.13, CIP 4400168, TIS.2544 Rusanya 1.5, TIS.82/0270.OP.1.85, TIS.82/0070.OP.120, TIS.8/637, NRCRI/UN/13, TIS.87/0087 and a farmer’s variety(Dan-Mangu), were screened during the cropping seasons of 2000 and 2001, to evaluate their yield potentials under the Jos-Plateau environment. The randomized complete block design was used with four replications. On t...
ABSTRACT Honey is a sweet, thick and viscid fluid collected from beehives and usually found in cells of the honey comb. It is produced from nectar collected from various flowers by honeybees and processed. Among the important uses, pure and undiluted honey serves as natural sweetener and contains a broad variety of vitamins for human consumption. Due to its global demand, monitoring of the quality of honey is of great significance. In this study, honey samples were collected systematically fr...
A total of 1,075 fasting Human Serum and early morning urine samples were assayed for various biochemical parameters. The parameters include: Blood lipids, Total Cholesterol, High Density lipoproteins, Low Density lipoproteins, Vitamin A, Sodium, Potassium, Chloride, Bicarbonate, Urinary glucose, Protein and Blood. From the results obtained, the calculated phospholipids:cholesterol ratio was less than 1 amongst the hypertensives. This confirmed the work of Stroev and Makarova, 1986; Of...
ABSTRACT Mycoflora of mixed maize grains and the newly developed Abeleehi and Obaatanpa varieties and airspora in the Warehouse o f the Ghana Food Distribution, GFDC, at Balduzzi, Kumasi have been studied under normal and simulated ambient Environmental Relative Humidities (ERH ’s) representative of the Ghanaian conditions. Some important physical and processing characteristics of £. and normal stackbumed white and yellow maize (seed water absorption, swelling index, 1000-seed weight, ferm...
ABSTRACT The environmental impact of the Liquefied Natural Gas (LNG) Company for the environment and social conditions using the Nigeria Liquefied Natural Gas (NLNG) in Rivers State, Niger Delta area of Nigeria as a case study is analysed in this paper. Specifically, the paper analyses the environment and social consequences of the operations of NLNG on the immediate environment. Data were collected from both the secondary and primary sources. The paper reveals that air borne diseases are the...
