ABSTRACT This study delved on the Implementation and Performance Evaluation of the Dual Stack Transition Mechanism at the UDOM LAN. The implementation phase involved simulating the network in the GNS3 simulator in which a number of hops were varied between 1 and 6. In addition, RIPv2 and RIPng were used as the dynamic routing protocols. The protocols were configured on each router interface to enable communication between the connected routers. After the implementation and configuration, the ...
ABSTRACT This dissertation investigates the magnetic field and Soret influence on MHD unsteady free convection radiating and reacting fluid past an exponentially accelerated inclined infinite porous plate of uniform permeability with variable temperature and concentration numerically. In this model the fluid is considered a gray, emitting absorbing radiation but a non-scattering medium and a magnetic field of intensity B0 is imposed in the perpendicular direction to the plate. The governing e...
Abstract Namibia is among the Sub-Sahara African countries with a high burden of TB and HIV coinfection in the world. The interaction between TB and HIV/AIDS makes the diagnosis and management of the co-infection difficult. The purpose of this study is to identify risk factors, assess spatial and space-time clusters mortality among TB and HIV in Erongo Region. A retrospective cohort study from 2003 to 2017 was carried out using data consisting of 3145 subjects from all the 16 health faciliti...
ABSTRACT The primary target for atherosclerosis associated cardiovascular (AACV) risk prediction and treatment assessment is the lipid profile fraction of low-density lipoprotein cholesterol (LDLC). The routinely used Friedewald method for LDLC estimation has an unacceptably high analytical error. In this study, patient sera LDLC was estimated using the Friedewald method (LLC) and the Roche Diagnostics direct homogeneous method (dLDLC). Serum lipid calculations of non-HDLC, HDLC/LDLC ratios,...
ABSTRACT Malnutrition remains a factor, directly or indirectly, in 60% of 11 million deaths of children aged less than five years globally each year. Hence, proper nutrition during infancy and early childhood is fundamental to the development of a child’s potential for normal growth, development, and survival of infants and children, particularly in developing. This study intent was to examine feeding patterns, practices and factors associated with exclusive breastfeeding and complementary...
ABSTRACT The study has intended to investigate the application of mobile phones in information dissemination regarding pests control and diseases management for vegetable crops with a consideration of tomatoes productions in Kilolo district. The study aimed at bridging the gap that exists between farmers and agricultural officers. The study involved two wards, and was mainly qualitative supported by quantitative research paradigms to collect and analyse data from tomato farmers, ICT expertise...
ABSTRACT Dye-Sensitized Solar Cells (DSSCs) are promising third-generation photovoltaic devices that offer the conversion of light energy into electricity at a lower cost. At the heart of this device is a sensitizer (dye) adsorbed on TiO2-photoanode, which is responsible for the harvesting of visible light energy. However, the currently used sensitizers offer little improvement to the overall cell efficiency and this constitutes the main challenge to this technology. This work reports a comb...
ABSTRACT Namibia has been known as water-scarce, attributing mostly to its geographic location and primarily because of the limited surface water as well as the high potential evaporation rates beyond 2000 mm/year. Groundwater therefore quickly becomes crucial, most of which is located in aquifers in the savannah biome which covers a large part of the country. This is also where most industrialization, as well as most farming, is practised. It is however unknown how these savannah aquifers ...
ABSTRACT This study was conducted at Sarusungu Border Post, a socio-economic conduit at Rundu-Calais Bridgehead in Kavango East Region. The research investigated Informal Cross Border trade patterns, pro-poor benefits and hindrances of Informal Cross Border Trade (ICBT). The investigation used a qualitative approach in form of semi-structured interviews and field observation. The study had a sample of 55 participants consisting of informal traders, money exchangers, border officials and key ...
ABSTRACT Globally, with rapid urbanization in most cities of the World, more people are now living in urban areas than in rural areas. The housing backlog coupled with a shortage of housing subsidies means that for many there is no alternative but to live in informal settlements. Urban food insecurity is often overlooked since, at the aggregate level, economic and social conditions in urban areas are much better than those in rural areas. The urban poor often live in neighbourhoods with poo...
ABSTRACT The dissertation examined the development and potential prospects of three diverse mining settlements in Namibia - Rosh Pinah, Klein Aub, and Tsumeb. It is a case study in settlement, geography aiming to investigate problem areas and their potential the solution towards sustaining people-centred urban stability, growth and development, linked to the assistance of private-public local and regional development planning in an environment of global mining competition. The integrative li...
Abstract Albizia anthelmintica belongs to the family Fabaceae. The plant is traditionally used to treat symptoms of microbial infections in both humans and animals. The present study was designed to evaluate the phytochemical content, antibacterial and antioxidant activities of A. anthelmintica leaves, roots and stem bark ethanol extracts. Antibacterial activity was carried out by means of the agar disc diffusion method. The anti-oxidative activities of the extracts were determined by means o...
Abstract Over the past few decades metals in medicine have played to play a significant role, especially after the discovery of the anticancer properties of cisplatin. However, acquired and intrinsic resistance, toxicity and a host of side-effects have encouraged the research for new metal based anticancer agents. Organometallic complexes have proved to be successful anticancer agents and several have commenced clinical trials. The aim of this study was to prepare and characterize trinuclear ...
Abstract The phenomenon and increasing rate of urbanisation is causing many researchers to look deeper at life in cities. Increasingly recognised are the benefits of urban green space and their associated recreational parks and nature reserves. While there is a growing literature on the environmental services provided by these areas; so too is there a growing literature on the numerous social benefits that recreational green spaces in particular afford their users. Although imagined and gener...
Abstract Erica makes up 7% of all species in the Cape flora. It is the most species-rich genus in the Cape Floristic Region (CFR), which has an area 0f 90 000km2. Erica species have great inter- and intra-specific variation in floral form as well as in post-fire regeneration strategies. Previous studies of other plant groups (Barrett et al. 1996; Button et al. 2012) have illustrated changes in floral traits with a shift from outcrossing to selfing. The aim of this thesis was to determine whet...
