ABSTRACT The large-scale production of mine wastes and their secure disposal has been a problem of global importance. In this work, the mine waste from Merelani, crude overburden pyrite ore was converted into a value added chemical, sulphuric acid. XRF, XRD, AAS and modified ASTM D-2492 tests were used to investigate the mineral and chemical composition of the ore. It was revealed that the ore comprised about 60% w/w of mineral pyrite (FeS2). The evaluation of XRD pattern shows that the pyri...
ABSTRACT This thesis sought to examine the dynamics of community participation and accountability in Tanzania and its effect on the development management of water programs in local government authorities in Tanzania with special focus on water programs in the two districts of Kilolo and Kongwa. The study is based on the premise that community participation and accountability in development are equally important as they enhances the quality and relevance of development processes and their ou...
ABSTRACT This thesis examines how local television soap operas influence perceptions and attitudes among audience in Tanzania. The general view of the related literature was that soap operas which have been produced in developing countries like Tanzania are principally pro-development in nature and are so designed. However, neither had any scientific study been conducted within the country to prove this view with regard to local television soap operas, norhad any researcher focused their stu...
Abstract This research argues the thesis that the logical atomistic epistemology of Bertrand russel is entrenched in british empiricist pluralistic metaphysics
Abstract This research dissertation was undertaken to increase knowledge of the effects of AIDS related adult mortality on family structures in Namibia. Previous research focused mainly on very specific effects like food security or the needs of OVCs. This research includes changes in family size, form, composition, economic activities and distribution of the care burden as a result of AIDS related adult morbidity and mortality. The researcher combined a critical approach towards the literatu...
ABSTRACT Title: Antecedents and outcomes of work-related psychological well-being of staff members of the University of Namibia Key words: Well-being, work engagement, psychological meaningfulness, psychological safety, psychological availability, higher education The aim of this study was to investigate the antecedents of work-related psychological well-being and the individual and organisational outcomes thereof for staff members of the University of Namibia. Psychological well-being was co...
ABSTRACT Namibia is one of the driest countries in Sub-Saharan Africa, and man-made dams play an important role on salvaging water. These dams are however periodically frequented by microalgae blooms that pose devastating effects on the water quality, making water treatment processes troublesome and cost prohibitive. However, these unicellular organisms can be exploited in various ways especially when cultivated in controlled and closed systems under optimal conditions of light, temperature, ...
ABSTRACT Malaria, a parasitic infectious disease, remains one of the world’s foremost health concerns, even more so in developing countries. Much progress has been made in fighting the disease, particularly in Southern Africa where four countries (Namibia included) have targeted malaria elimination by 2020. Challenges such as the absence of a vaccine, resistance to insecticides, and particularly the emergence of resistance to current antimalarial treatment regimens threaten to undermine the...
Abstract African ontology, for the most part, has been premised on an ancient theory of forces hierarchicized in an inseparable continuum. The basic assumption that forces interact, intermingle and interpenetrate one another informed the extended family relations which stresses the brotherhood of man and the communion of souls from which architects of African societies in the post-colonial era constructed primitive socialism(s) and primitive capitalism( s). The purist school of thought in Af...
Abstract The main aim of this study was to investigate potentially pathogenic community-associated staphylococci in school children. Objectives were: To determine the prevalence of nasal Staphylococcus aureus and coagulase-negative staphylococci (CoNS) in school children from the Mariental District; to characterize the bacteria in terms of their antibiograms and drug resistance patterns; to screen bacterial isolates for their ability to produce enterotoxins and produce biofilms as potential v...
Abstract Disease mapping has important applications in public health because it enables the identication of areas which are at high risk of particular health problems. It helps visualising the spatial pattern of the disease distribution, which is of interest to the health sector as it enables the sector to plan, evaluate and redesign prevention and control strategies, and also make important policy decisions particularly for geographically targeted intervention in resource poor settings. Anal...
ABSTRACT This study investigated tertiary lecturers’ and students’ perceptions and preferences on the provision of corrective feedback in the English as a Second Language (ESL) classroom at the Namibia University of Science and Technology. The study focused on students’ speaking and writing skills in the English course, Language in Practice. This study used a triangulation design for data collection and analysis. Numerical data were obtained through closed-response items on questionnair...
Abstract The San people are indigenous minorities in Namibia that are known for their hunting and gathering lifestyle. From personal observations, discussions, interviews, raw data from Tsintsabis clinic and results obtained from the research, one had to assume that the San people are immune to malaria. It is unclear how the disease does not affect them although they live in endemic areas. The objective of this study was to investigate how the San have survived without a major outbreak of mal...
Abstract Marama bean [Tylosema esculentum (Burchell) Schreiber] belongs to the family Fabaceae and is a candidate for domestication in arid zones. It is indigenous to the Kalahari regions of Southern Africa thriving in low nutrient and low moisture soils. Marama bean seeds exhibit high oil (up to 48%) and protein (up to 42%) content comparable to peanut and soybean respectively. The main purpose of this study was to determine the usefulness of previously developed microsatellite markers in di...
ABSTRACT The thesis explored the dynamics of the rhetoric of the language of science on climate change publications. The arguments presented in this study were drawn from a theoretical framework that saw rhetorical arguments, texts and general discourse as instruments of communication of science publications on climate change in Namibia. Thus, Rhetorical Structure Theory (RST) was used in this study. The theoretical framework of the study was extended to incorporate the Aristotelian rhetorica...
