ABSTRACT The 22.5 km2 Kobada project which is located in the Kangaba Cercle of the Koulikouro region of Mali, is owned and operated by African Gold Group Inc. (AGG), a Canadian junior exploration company (Fig. 1.1 shows perimeter for 22.5 km2; fig. 1.9 shows perimeter for consolidated permit of 215 km2). Notably the permit hosts a soil anomaly greater than 500 ppm arsenic that extends over 12 km of strike length and one kilometre of width, which is offset to the west of extensive artisanal su...
ABSTRACT This study, undertaken during 1974 to 1977 in Volta Lake, investigated the identification, abundance and distribution, reproductive biology and weight-length relationships of four Chrysichthys species (C . a u ratus, C. walkeri, C. velifer and C. furcatus). The species were separated on basis of position of the dorsal fin, color of the barbels and the body and shape of the caudal fin and its lobes. Gill rakers also proved of some value. The Volta Lake, on the Volta River in Ghana, is...
ABSTRACT Globally three (3) billion people use inefficient cook stoves and fuels and the smoke emitted from these cook stoves leads to 4.3 million deaths per year. In Ghana, 70% of households use traditional cook stoves and solid fuels whose emissions lead to 17,000 deaths every year with 50% of them being children under five (5) years of age. Whilst the negative health impacts of the emissions generated by these cook stoves is increasingly being recognized, there are limited varieties of imp...
ABSTRACT Honey is the most commercialized bee product in Ghana. It is utilized by all age groups and religious bodies with increasing demand. However, the production, packaging and handling has been associated with unsanitary and unhygienic practices with scanty documented information on production practices. Most of the artisanal honey are also mainly retailed in places where environmental conditions and handling practices do not meet fundamental food hygiene standards. This study sought to ...
ABSTRACT Functional foods are foods that possess other health benefits apart from their regular nutritional benefits. A functional food may contain nutraceutical properties, which have components, responsible for curing or preventing a disease or disorder. There are several indigenous foods in Ghana that have been purported to possess functional properties. The claim to functionality of some of these indigenous foods are based on folklore but the scientific backing to these claims may not be ...
ABSTRACT Background: Worldwide the hepatitis B virus (HBV) infection is considered a major public health concern, infecting about two billion people. Annually, the disease accounts for about one million deaths. The prevalence of the disease is considered high in Africa, affecting about 8% of the population in West Africa and between 5 to 7% in Southern, Eastern, and Central Africa. Ghana has a high prevalence rate of 12.3% with most infected persons seeking medical attention at the terminal s...
ABSTRACT The research is based on financial time series modelling with special application to modelling inflation data for Ghana. In particular the theory of time series is explored and applied to the inflation data spanning from January 1965 to December 2012 which were obtained from the Ghana Statistical Service. Three Autoregressive Conditional Heteroscedastic (ARCH) family type models (traditional ARCH, Generalized ARCH (GARCH), and the Exponential GARCH (EGARCH)) models were fitted to the...
ABSTRACT In this thesis, the notion of quasiconvex functions on time scales and some properties are established. The subdifferential for quasiconvex function on time scales is presented as well as some properties regarding quasiconvex function. Some Jensen’s inequalities for quasiconvex functions on time scales are also given with some applications. The study again proves that Jensen’s inequality holds for quasiconcave monetary utility function in conjunction with convex, concave, quasi...
ABSTRACT The Currency in Circulation is the outstanding amount of notes and COIns circulated in the economy and are the most liquid monetary aggregate. In this study, data on monthly Currency in Circulation obtained from the Bank of Ghana database was modelled using both SARIMA model and Regression model with ARIMA errors. The results revealed that ARIMA (0, 1, 1)(0, 1, 1)12 model was the best SARIMA model for the Currency in Circulation. This model has the least AIC of -372.16, AICc of -37...
ABSTRACT The study focused on the assessment of stakeholders participation as a determinant for effective land use plans implementation in the Tamale Metropolis of Northern Region of Ghana. Primary data was then collected from households and institutions and analyzed. The study revealed that those factors such as leadership qualities, transparency, resources availability and centralization of decisions affect successful stakeholders’ participation in implementation of land use plans. The ...
ABSTRACT Generally this research used Linear Programming techniques to investigate the budgetary allocation of MTN Company for effective media selection planning. The problem was formulated as a linear programming technique by using the available data obtained from the company and other media sources. Mathematical software which embodied the simplex algorithm techniques such as Quantitative Manager for Business version 3.2 and Linear Programming Solver version 5.2.2 were used to solve the res...
ABSTRACT Acute respiratory infection (ARI) range, in spectrum, from mild colds and coughs to life threatening pneumonias. ARI particularly pneumonia is the major cause of morbidity and mortality among young children under five in developing countries with Ghana not an exception. In this study, we compared the linear SARIMA Model and the nonlinear two regime SETAR Model in predicting pneumonia cases in northern region of Ghana. Data on monthly pneumonia cases obtained from the Tamale Teachin...
ABSTRACT This thesis investigates the Application of Queuing theory to customer services at selected branches of the Standard Chartered Bank in Accra. The problem investigated was to determine among other things whether the customer service points of the bank functions well without bottlenecks or undue delays. That is this thesis intends to investigate, (a) If the bank current system of operation at the customer service points is satisfactory. (b) If not what changes are required to improve t...
ABSTRACT Nanocrystalline zinc oxide particles were synthesized via sol-gel method using zinc acetate as precursor. Calcination temperature was varied to determine its effect on particle size. The resultant samples were subjected to X-ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), UVvisible and Scanning Electron Microscopy (SEM) characterization techniques. X-ray diffraction results showed nanocrystalline wurtzite ZnO particles with crystallite size ranging from 16 nm to 30 nm resp...
ABSTRACT Acquired Immune deficiency Syndrome (AIDS) is a disease caused by a virus known as Human Immunodeficiency virus (HIV). This virus attacks a person's immune system (white blood cells) and as such weakens the immune system and making the person vulnerable to opportunistic diseases e.g. tuberculosis, diarrhoea, to mention a few. HIV was first diagnosed more than twenty years ago and up to now there is no known cure for the disease. The rate at which HIV is spreading in sub-Sahara ...
