ABSTRACT Type 2 diabetes is a global problem that can be controlled by a diet that consists of carbohydrates with substantial amounts of slowly digestible starch amongst others. Pearl millet (Pennisetum glaucum (L) R. Br.) is an underutilised cereal crop that in recent times, raised interest due to its health benefits. The low starch hydrolysis rate of pearl millet is particularly of interest in type 2 diabetes modulation. To contribute to the value-addition and food diversification using pe...
Abstract. In this paper, we present the (p,q)-analogues of some inequalities concerning the digamma function. Our results generalize some earlier results.
ABSTRACT Bush encroachment, characterized by increase in woody plants in ecosystems, is one of the manifestations of environmental degradation that is prevalent in many parts of Namibia. The present study was conducted in Ben Hur area in the Omaheke Region, about 60 km South-East of Gobabis with the objectives of comparing family diversity, abundance and composition of ground dwelling invertebrates in habitats that are at different levels of bush encroachment and determining their seasonal v...
Abstract Ganoderma lucidum (Fr.) Karst. (Ganodermataceae) is a natural scarce basidiomycetous polypore fungus that has a variety of uses such as providing nutrition and as a medical remedy. It has been used in the Asian countries for many years to treat a wide range of ailments with polysaccharides, triterpenes, sterols, lectins and proteins as major active constituents. However, in Namibia, the traditional usage of the Ganoderma mushrooms have been used to relieve stress, calm nerves, heal ...
Abstract Some inequalities involving the k-digamma function are presented. These results are the k-analogues of some recent results.
ABSTRACT Mining is a major contributor to water pollution, which can lead to accumulation of heavy metals in aquatic systems. Mining activities in the Karstveld, specifically in the Tsumeb-Grootfontein-Otavi area, may potentially result in heavy metal pollution of water sources. A seasonal study was conducted to assess the concentration of heavy metals in aquatic systems that receive water from the Karstveld aquifer. The potential of locally occurring fish and crab species as bio-indicators ...
Abstract The accident risks of drivers and the factors affecting the risks were analyzed using survival models. The data consisted detailed records of fatal accidents in the years 2007 - 2009, generated by the Motor Traffic and Transport Unit (MTTU) of the Ghana Police Service, Northern region. The data on fatal accidents contained 398 drivers. The objectives of the study included both analysis and explanation of driver accident risk factors and investigation of how survival modeling method ...
ABSTRACT Ozone (O3) is an allotrope of oxygen occurring naturally in the earth’s atmosphere. Its importance in environmental issues is well documented and cannot be overemphasized. Ozone reacts with carbon-carbon multiple bonds such as in alkenes via the ozonolysis process. The first step of ozonolysis involves the formation of an important but very unstable primary ozonide (POZ) which after formation, immediately rearranges to the more stable secondary ozonide (SOZ). Due to its instabilit...
ABSTRACT Three medicinal plant parts, including the leaves of Senna alata, Ricinus communis and the stem bark of Lannea barteri were used for the current study. The aim was to investigate the antimicrobial effect of the crude extracts alone, their combinations and the crude extracts formulated individually with polyethylene glycol (PEG) and Shea butter, as well as phytochemical screening of the medicinal plants crude extracts. The microorganisms employed in this study were E. coli, S. aureus...

ABSTRACT The study focused on analysing geospatial internet customer satisfaction levels, using the Geographic Information System (GIS) technology. The aim of the study was to investigate how demographic and economic factors influence satisfaction levels. The study followed a quantitative design and employed the systematic sampling method to select a sample of 248 potential internet users. A structured self-administered questionnaire was used to collect data from selected samples. The statis...
ABSTRACT Hawked foods are cheap and easily accessible and have met the food needs of people in many cities and towns of developing countries. This study was aimed at ascertaining the diversity of microbial contaminants in foods hawked in Nsukka town. Seven different food samples of cooked foods hawked in Nsukka were examined for the presence of bacterial and fungal contaminants using the streak plate method on sterile nutrient agar plates and SDA plates respectively. The foods included; pige...
Abstract The Kavango region is extensively involved in agriculture and is also known to be dominated by sandy arenosols. The bad soils in the region, which have poor nutrients and water holding capacity, combined with climate change have contributed to the reduction in yield of most crops grown in the area. One of the aims of this study was to isolate and identify cowpea nodule symbionts from soils in the Kavango Region while the other was to determine cowpeas’ response to bio-inoculants b...
Abstract Motor Vehicle Traffic Crashes (MVTC) are one of the leading causes of death and disability in the world, especially in developing countries. Despite Namibia having a well- developed road network, MVTC are the third highest cause of death in the country with 23.9 per 100 000 MVTC fatality rate recorded. This study was conducted in Namibia to model factors affecting the severity of injuries from MVTC. The study purpose was to examine the effects of human, crash/accident types, environ...
ABSTRACT Physicochemical and bacteriological analyses of borehole water samples were randomly collected from ten boreholes that supply drinking water to various communities of Aninri, Awgu and Oji River Local Government Areas of Enugu, Nigeria. The boreholes were sampled in both dry and rainy seasons. The following physicochemical parameters: pH, temperature, colour, electrical conductivity, turbidity, total dissolved solids, hardness, calcium, magnesium, sodium, potassium, alkalinity, acidi...
