ABSTRACT In Namibia, non-communicable diseases are on the increase. Statistics on noncommunicable diseases (cancer, diabetes, cardiovascular diseases, hypertension etc.) as a cause of morbidity and mortality indicate that it is a public health concern although population based estimates in the area are lacking. The Ministry of Health and Social Services stated that between 2004 and 2008, hospital based mortality due to cancer (all types) increased from 3.2% to 54.7%, cardiovascular diseases ...
ABSTRACT Namibia has a rich biodiversity of plant species of which a great variety is used for food, cosmetics and medicinal applications. Seed oil production from indigenous sources has economic importance for Namibia and is an asset for improving the livelihoods of local communities. Knowledge of the quality and composition of these oils can be used towards value-added product development strategies and improved marketing of indigenous resources. A comprehensive profile of indigenous seed ...
ABSTRACT In recent years, there has been an increase in fatal road accidents in Namibia claiming many lives each year. Traffic accidents are often related to the use of alcohol, illegal drugs or psychoactive medicines. A rapid low volume dispersive liquid-liquid microextraction (DLLME) method in combination with gas chromatography-mass spectrometry (GC-MS) detection was developed for the simultaneous determination of illicit psychoactive drugs in blood (those used most commonly in Namibia: c...
ABSTRACT Cancer is a universal disease that affects people regardless of race, sex, socio-economic status and culture. With just an approximated population size of 2.3 million people NSA (2011), Namibia is not excluded from this. If not detected on time and treated on time, cancer can make treatment less likely to succeed and reduce the chances of survival. The study was aimed at examining the prevalence and trends for breast cancer patients, regardless of patients’ sex, as well as establi...
ABSTRACT Studies were conducted over a period of three years (2011 to 2013) at the Ogongo Campus of the University of Namibia (UNAM), to compare the differences between tractors and animaldrawn implements both using conventional and Namibia Specific Conservation Tillage (NSCT) technologies. Two conventional tillage (CV) treatments (i.e. tractor-drawn disc harrow (TDH) and animal-drawn mouldboard plough (AMP) were compared to two NSCT treatments (tractor-drawn ripper furrower (TRF) and animal...
Abstract Metal nanoparticles are endowed with optical, electrical physical and chemical properties and have become attractive materials for commercialization applications in optical spectroscopies, electrical devices and catalytic applications. Among them, silver nanoparticles (Ag-NPs) have distinctive physico-chemical and biological properties such as antimicrobial, chemical stability and catalytic properties. Namibia, a semi-arid country, relies on man-made dams to obtain water for potable...
ABSTRACT Tephrosia lupinifolia is used traditionally for the treatment of malaria, diarrhea, toothache and tuberculosis. Two flavonoids, lupinifolin and lupinifolinol were previously isolated from the hexane root extract of T. lupinifolia, but there are no reports on phytochemical and pharmacological studies conducted on the stems and leaves of the plant. The purpose of this study was to prepare and fractionate crude extracts from the leaves and stems of T. lupinifolia, and to evaluate their...
ABSTRACT Bacteria belonging to the genus bifidobacteria are reported to be the most abundant gut endosymbiotic flora in the intestinal tract of new-born infants, particularly those that have been exclusively breast-fed. This high concentration of this gram-positive anaerobic bacteria has been attributed to the prebiotic and bifidogenic factors present in human breast milk. Currently, there is limited information on the presence of bifidobacteri aspecies in Namibia. The aims of this study wer...
ABSTRACT The main purpose of this study was to investigate the challenges affecting Grade 12 learners’ academic performance in Namibia Senior Secondary Certificate Ordinary level (NSSCO) Biology in the //Kharas Region, Namibia. The study addressed three research questions. Two categories of sample, made up of 140 learners and 12 teachers respectively were selected using the simple random sampling method to participate in the study. Furthermore, after the preliminary analysis of the questio...
Abstract This study attempted to find out how mobile technologies could be used to implement Web 2.0 based service delivery to graduate students based in the Graduate School of the University for Development Studies (UDS) Library. A 23 item questionnaire was administered to a sample of 155 participants who were selected by means of simple random sampling. A total of 119 questionnaires were retrieved and found to be adequate for analysis and interpretation. The collected data was analyzed and...
Abstract Information and Communications Technology is improving at a very high pace. Software applications can be delivered in various forms, the internet growth has made it possible to have software delivered over the internet. One of the most interesting models created by the web is called Application Service Provider (ASP) model. ASP model offers completely a new way of selling and distributing software and software services. ASP services are expected to become an important alternative fo...
ABSTRACT The study attempts to determine whether the mood of teachers have any direct bearing on the academic performance of students in class. The study area was Morso D/A J.H.S. A sample size of forty students from form two was used for the study. The affect theory by Tomkins and the behavioral theory by Bandura was adopted as framework for this study. The random sampling technique was employed to select the samples into two groups of students each comprising of twenty, the groups were tau...
Abstract Advances in radio astronomy are allowing for deeper and larger observations than ever before. Source counts of future radio surveys are expected to number in the tens of millions. Source finding techniques are used to identify sources in a radio image, however, these techniques identify single distinct sources and are unable to identify multi-component sources, that is to say, where two or more distinct sources belong to the same underlying physical phenomenon, such as a radio galaxy...
ABSTRACT The hydrogeological system of the Ga East and Adentan Districts of the Greater Accra Region of Ghana was studied using numerical modelling on the Groundwater Modelling System platform (version 10.0). Historical hydrogeological data and groundwater monitoring data on twenty wells drilled in 2012 were relied on in conceptualising the hydrogeological system of the study area. A single aquifer system made up of quartzite-schist formation was identified. The borehole logs reveal four lith...
ABSTRACT One of the most spectacular changes in Ghana since the 1980‘s after World Bank and International Monetary Fund programmmes (ERP and SAP) has been the dramatic demographic shift skewed in favour of cities. With fewer than 49 percent of its people being rural, the 2010 population census indicated that the country is currently 50.9 percent urbanized. Accompanying such demographic explosion is the challenge of developing the needed infrastructural resources to deal with urban growth an...
