ABSTRACT In the present scenario of the over dependence and shortcomings of fossil fuels, integrated biorefinery techniques have been developed to process biodegradable and sustainable feedstock for use as green energy. Brown seaweed biomass, recently has been under the spotlight for the production of biogas via anaerobic digestion. In this study, the effects of acclimatising inoculum to Ecklonia maxima, a brown seaweed type for the production of biogas have been investigated. Biomass of Eckl...
ABSTRACT Background: Adolescent offenders in juvenile detention centers are generally dependent on the centers for their nutrient intakes, and therefore their food selection may be limited, which could have a negative consequences for their nutritional status. We examined the nutritional status of adolescent inmates at the Senior Correctional Centre, Junior Girls Correctional Centre and the Boys Remand Home in Accra Methods: The study was cross-sectional involving inmates (N= 79) between 13-1...
ABSTRACT Globally, attention and investments towards demand-side strategies to enhance health care utilisation have improved over the years. Despite this significant investment in health care, its utilisation is far from adequate. Against this backdrop, this study examined the utilisation of health services in the Obuasi Municipality. Drawing on Kroeger’s (1983) health behavioural model, it specifically examined the incidence of major diseases and people’s perception about disease causati...
ABSTRACT Exposure to television (TV) is reported to be associated with unhealthy dietary behaviours among children. The surge in new television channels on TV sets in Ghana comes with all sort of advertisements. The aim of the current survey was to examine the nature and content of television food advertising and to explore the association between such exposure and children’s food preferences. In a cross-sectional survey with multistage sampling, 400 primary school children (mean age 10 (S...
ABSTRACT The validity and quality of data analysis relies largely on the data accuracy and completeness of the data matrix. Missing values are unavoidable statistical research problems in almost every research study and if not handled properly, may provide negative and bias conclusion. This study purposely sought to investigate the efficacy and accuracy of the convergence of five imputation algorithms: expectation maximization (EM), multiple imputation by chained equation (MICE), k nearest ne...
Abstract This study is about the spatial patterns of the Mycobacterium ulcerans infections (Buruli ulcer) in the Akwapim South district. The Triangle of Human Ecology model was used to account for the observed spatial patterns of the disease. The spatial distribution of the disease was mapped through the residential addresses of the patients as shown in the district medical records. The endemic communities were stratified into three segments namely the high, low and nonendemic areas or zones....
ABSTRACT Background Placental malaria and preeclampsia are major complications of pregnancy associated with high incidence of maternal/foetal morbidity and mortality particularly in sub-Saharan Africa. Similarities in pathophysiology such as systemic inflammation and generalized endothelial activation/dysfunction exist and are exacerbated in concurrent situations. The combined pathologic and immunologic effects of these pregnancy disorders, prevalent in malaria endemic regions, have not been ...
ABSTRACT The Southern Margin forest type in Ghana now occur in small forest fragments due to the overharvesting of plant resources for purpose of food, medicine, construction and fuelwood. The proposed Apra Hills Forest Reserve is one of the remaining forest fragments of this forest type in southern Ghana although there are no previous in depth studies to support effective forest management of its plant resources. In order to achieve the objectives of this study, plant diversity study and eth...
ABSTRACT Anaemia in pregnancy continues to be a major public health problem affecting 45% of pregnant women in Ghana and 47% in the Northern Region. This study examined the impact of anaemia during the third trimester of pregnancy on birth outcomes in TataleSanguli and Zabzugu districts. The study employed a prospective cohort design using simple random sampling technique to sample 359 respondents. The data were collected using a structured questionnaire and analysed using the Statistical Pa...
ABSTRACT Several strategies have been put in place in an attempt to reduce childhood mortality in Ghana, however the proportions of death among neonates are still quite high. The study therefore seeks to model neonatal mortality using survival analysis approach. The data used for the study was obtained from the neonate’s folders at St. Jude Hospital in Obuasi in the Ashanti Region between January 1, 2012 and December 31, 2015. Data on maternal characteristics was also obtained. Neonates who...
INTRODUCTION The physics design of nuclear reactors requires the determination of the gross statistical behaviour of the neutron population in the reactor system. This in turn calls for the solution of the Boltzmann equation of neutron transport theory which forms the subject matter of reactor theory. It is however not easy to solve this equation by a direct discretization process even on the largest computers because of the presence of too many independent variables, complicated energy varia...
ABSTRACT Survival analysis has been invaluable in studies involving time to an event. The methods encompassing the idea of Survival Analysis appears to be commended by most researchers particularly in the medicinal, engineering, agricultural and actuarial fields. This paper applied survival methods to promotion data of lecturers in the University of Ghana. The main objective was to identify the factors prominent in facilitating an early promotion of University of Ghana lecturers. The proporti...
ABSTRACT A revised generic diagnosis of the genus Rheotanytarsus Thienemann et Bause is given. Seven new Afrotropical species are described, R. kjaerandseni sp. n. as male, female, pupa and larva; R. plerusunguisus sp. n. as male and female; R. aquilus sp. n., R. atrius sp. n., R. saetheri sp. n., R* abonae sp. n., and R, weijensis sp. n. as males only. One species is redescribed, R. fuscus (Freeman, 1954). The genus can be divided into 7 species groups primarily based on the pupal morphology...
ABSTRACT The Mean Glandular Dose (MGD) was estimated first using Polymethylmethacrylate (PMMA) slabs and secondly MGD was estimated per right craniocaudal (RCC) projection view and left craniocaudal (LCC) projection view. A number of 21 patients out of a total of 28 patients, undergoing breast examination in three (3) selected mammography facilities in the Republic of Benin were involved. Image quality was evaluated based on subjective analysis of images with Leeds Tests Objects and American ...
Abstract Waste waters from eight selected industries namely Tema Oil Refinery, Tuyee Manufacturing Industries, Cocoa Processing Company, Tema Lube Oil Company Limited, Pioneer Food Cannery Limited, Bridaltrust Paints Company Limited, Ghana Textiles Manufacturing Company and Ghana Textiles Printing Company Limited were sampled and subjected to various physico-chemical and trace metal analysis to determine levels of pollutants, using standard methods of WHO, AO AC and APHA. Generally, the ROD v...
