ABSTRACT Spatial modelling is one approach that can serve as a basic tool in identifying areas that need intervention. Understanding the spatial distribution of indicators is of vital importance, as it help with national planning and decision-making. Different models such as Conditional Autoregressive (CAR) can be used in spatial modelling. However, these models pose analytic and statistical inferential challenges especially when non-continuous and multivariate response are involved. Therefor...
ABSTRACT The study of an inverse problem for elliptic partial differential equations has been put in place in order to provide a broad understanding to the existence of inverse problems for elliptic partial differential equations particularly Poisson’s equation. The main obective is to describe different approaches to inverse problems for elliptic partial differential equations and in particular, the factorization method. Another aim of this work is to study a certain inverse problem for a...
ABSTRACT Injuries caused by Motor Vehicle crashes were ranked 10th among the leading causes of death and 9th among the leading cause of disability worldwide (World Health Organization, 2013). In developing countries 90% of disabilities are caused by road traffic crashes. In Namibia, The Motor Vehicle Accident Fund spends approximately N$ 22,6 million monthly towards medical expenses of people injured in crashes (Tjihenuna, 2015), causing a concern, to the victims, their families and affects t...
ABSTRACT Moringa ovalifolia (African Moringa) is endemic to southern Africa, and it is distributed from southern to central Namibia to south western Angola. At the moment, little is documented on the phytochemical content, miro-nutrients and antioxidant activities of M. ovalifolia. Hence, this study was aimed at evaluating the phytochemical, micro- nutritients and antioxidant activities of M. ovalifolia. Fresh Moringa leaves, bark, flowers and seeds (ponds) were collected from five different ...
ABSTRACT The occurrence of Salmonella is a global challenge in the public health and food production sectors. Contaminated beef and animal feed with Salmonella may lead to infections of humans through food chain. The present study investigated the prevalence, serovar and antimicrobial resistance of strains of Salmonella serovars isolated from beef (meat cuts, meat fluid and carcass swabs) and animal feed (meat-and-bone, and blood meal) samples from the abattoirs in Namibia. Beef (9508) and an...
ABSTRACT The study was conducted to investigate the antibacterial activities of stem and leaves from Terminalia sericea and the live and dead bark from Combretum imberbe. The aqueous and organic crude extracts of the two plants were tested on Gram-negative bacteria Escherichia coli, Shigella sonnei, Serratia marcescens, Helicobacter pylori and Gram-positive bacteria Enterococcus faecalis, Staphylococcus aureus and Clostridium perfringens using the disk diffusion method. All the crude extracts...
ABSTRACT Namibia is experiencing an increase in its population living in urban areas due to rapid urbanisation. However, this growth has not been the same in all parts of the country. Currently the biggest growth rate is experienced in Windhoek, which is home to about 16% of the total population. Due to rapid population growth, Windhoek has been facing a number of challenges such as high unemployment rate, illegal land occupation, and development of informal settlements among others. As a res...
ABSTRACT Nutritional levels can have profound impact on individuals living with HIV/AIDS and potentially hinder the effectiveness of antiretroviral therapy (ART). But sufficient data is lacking to establish a strong relationship especially in Namibia. In this study, the relationship between CD4 counts, viral load (VL), prescribed first line antiretroviral combinations, micronutrient levels and age was explored. Data spanning from 2006 to 2015 were retrospectively collected from Katutura State...
Abstract This paper employ various econometric techniques to analyze the determinants of inflation in Namibia, focusing particularly on the relationships that exist between the Namibian price, as the dependant variable, and the real Gross Domestics Product, Broad money supply, interest rate, and South African Price index as well as the United States price index, being the explanatory variables and probable determinants of inflation rate in Namibia.. Inflation equations that were estimated use...
ABSTRACT Gold Fields Ghana Limited (GFGL) has several gold mining concessions situated in Ghana with granted Mining Leases of which the Teberebie Mine is an essential part and still in production. The Teberebie Mine which is found within the Takwaian district is located some 70 km north of the city of Takoradi, and 10 kilometres south-west of Tarkwa. The Mantraim central project known as "Mantraim Central" is a part of the main Mantraim project which has been drilled extensively to grade con...
ABSTRACT Elephants like most animals have different body condition, which in many cases is usually a reflection of their body fat content, food availability, presence or absence of diseases or disorders. Body condition in elephants and other factors that might affect it are not well studied. This study investigated the body condition of African elephants (Loxodonta africana) around the Mushara Waterhole in Etosha National Park, Namibia. The study focussed on possible correlations of body cond...
ABSTRACT Studies on laboratory colonies of Bulinus globosus from forest savannah and transition zones
GENERAL INTRODUCTION The family Synodontidae is a group of fish characterized by lizard-like head, spineless fins and a small adipose fin and are almost circumtropical in distribution.
A small proportion of sporangia of P. palmivora, less than 1.0 per cent, formed by hyphae growing on cocoa pods germinated in humid air at 25°C whilst still attached to the hypha.to produce germ tubes terminated by secondary sporangia.
ABSTRACT The objectives of this study were to confirm for the first time, the identity of Trametes mushrooms from Northern Namibia and then to generate information on local uses and bioactive compounds of these Trametes species. To achieve this, samples were collected from Ohangwena, Omusati, Oshikoto and Oshana regions and identified as Trametes species based on morphological features. These were a basidiocarp with concentric zones, brown, tan or grey colour and pores from 2-3 pores/mm to po...
