ABSTRACT Fresh groundwater resource located in the shallow semi-confined aquifer system of the White Volta River Basin of Ghana contributes significantly to the livelihood of the communities in the basin. The objectives of this study were to evaluate the spatial variations in the hydraulic parameters of the shallow aquifer system of the White Volta River Basin of Ghana, develop a 3 - dimensional groundwater flow model for the basin and assess various scenarios of groundwater development and c...
ABSTRACT Guinea Worm Disease (GWD) was officially reported in Ghana in 1965. As a result of the global campaign to eradicate the disease in the mid 1980s, Ghana investigated the magnitude of the disease on a pilot basis in the Northern Region. When it was established that the disease was a major public health problem in the country, Ghana started a local initiative towards eradicating the disease in 1986. Global assistance was extended to Ghana in its effort to eradicate the disease which was...
ABSTRACT According to Knorring and Kennedy (1958), scapolite occurs in rock volume proportions of 20% at the Mampong Inselberg but other areas in the Dahomeyide suture zone have scapolite in the mafic gneiss in volume proportions of about 2%.Also, the amphibolite which occurs with the mafic gneiss in the study area is said to have undergone granulite facies metamorphism to produce the mafic gneiss (Fitches, 1970). The petrographical analyses of this research showed that the mafic gneiss has s...
ABSTRACT The Rhodococcus sp. M1042 is a new microbial strain that was isolated from soil sediments collected from Munzur Valley in Tunceli, Turkey. Species in this genus have been found to harbour extensive secondary metabolic pathways that produce novel metabolites with bioactivity with industrial and environmental bio-applications. The complete genome sequence of this strain contains 5,948,800 mega base pairs with 230 NRPS, PKS and NRPS-PKS gene clusters, some of which have been identified ...
ABSTRACT This research is essentially an upgrade or extension of the results of Audu on wreath product of permutation groups. In this work, a generalization of the concept of wreath product is considered based on the notion of an algebraic structure called Permutation group. Some basic procedures for computing wreath products of groups, the construction of groups as wreath products of cyclic groups and a generation of Sylow p-subgroups from resulting Cyclic groups are investigated. I mainly a...
ABSTRACT Most of the concepts in theoretical and empirical finance that have been developed over the last 50 years rest upon the assumption that the return or price distribution for financial data follows a normal distribution. But this assumption is not justified by empirical data. Rather, the empirical observations (financial returns) exhibit excess kurtosis, more colloquially known as fat tails or heavy tails. This research first described the stable distribution family - stable, Lev...
ABSTRACT This study examines the long-run equilibrium relationship and the direction of causality between stock prices at Ghana Stock Exchange (GSE) and a set of five stock market oriented factors technically can be defined as microeconomic variables. The study employs time series data comprising of the stock prices of listed companies for the period spanning from April 1998 to April, 2013 and key microeconomic variables, benchmarks of corporate performance, obtained from the annual financial...
ABSTRACT Medicinal plants represent an important class of various traditional medicines. Over the years, their usage in primary health care intervention has increased in both developed and developing nations. Nowadays herbs are known to be the storehouses of most potential toxic elements (PTEs). In Ghana, most studies on PTEs have focused on only single environmental compartment to characterize medicinal plant contamination. In the present study, an integrated sampling programme that relates ...
ABSTRACT Malaria and tuberculosis continue to be endemic in Africa and several other regions across the globe. Malaria is caused by a parasite transmitted by the female anopheles’ mosquito. Plasmodium falciparum is responsible for human malaria in most part of Africa and Plasmodium vivax causes malaria in Asia. Tuberculosis on the other hand is caused by Mycobacterium tuberculosis which is propelled when an infected person coughs, sneezes or even talks. Together, these two diseases are resp...
ABSTRACT Croton membranaceus is a herb with useful medicinal properties. The leaves, bark and roots are used for the treatment of diverse ailments. The harvesting of the plant by many traditional medical practioners from the wild for the treatment of diseases in the country without replacement exposes the plant to possible extinction in the near future. The only means of propagating the plant is by use of seeds which is relatively slow. Thus, an alternative mode of propagation is needed to de...
ABSTRACT The prime objective of the study was to introduce the application of a Bayesian method of estimation in the computation of the Gini coefficient. The bootstrap estimation technique was also employed to obtain confidence intervals for the estimated Gini coefficients which were used to statistically analyze the significant change of inter-household income inequality between 2005/06 and 2012/13 in Ghana with emphasis on the sex of head of household. Most of the methods used in calculatin...
ABSTRACT Conidia of Cercospora arachidicola are straw-coloured or olivaceous, subfusiform, multicellular, 28.3-68.1(jm in lengths. They contain 3-7 cells. They germinated in distilled water and at 85-100% R.H. The optimum pH for germination was 5.0-6.0; any cell of the conidium germinating produced only one germ tube. The germ tube commonly comes from the end cells with occasional germ tube emerging from one or two median cells. Pollen of Zea mays, glucose (1.0-8.0%) and peptone (0.1-2.0%) fa...
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 ...
ABSTRACT Conidia of T. fructigena did not germinate at any relative humidity from zero to 10C% R.H. Germination in distilled water^was very poor, less than 2.0 per cent at the optimum temperature, 25 C. PDA encouraged 96.8 percentage germination at 25°C. The conidia germinated very poorly on PDA at 35°C and a temperature of 40 C killed the conidia in approximately 1 2 hours. T, Frutiger conidia would only survive in atmospheres of extremely high humidity. Best survival occurred at 10($ R.H...
ABSTRACT Background: Employees of night clubs are at a greater risk for developing hearing loss because they could be exposed to dangerously high noise levels. Elevated noise levels may lead to adverse effects including elevated blood pressure and sleep interference. Communication in the workplace may also be affected, contributing to the occurrence of accidents. The most serious side effect of noise however is irreversible hearing impairment, and this occurs as a result of damage to the del...
