Assessment of heavy metal enrichment and degree of contamination around the copper-nickel mine in the Selebi Phikwe Region, Eastern Botswana
(Horizon Research Publishing Cooperation, 2013)This paper focuses on heavy metal (Co, Cu, Fe, Pb, Mn, Ni and Zn) enrichment and degree of contamination in the soils windward of the Selebi Phikwe copper and nickel mine (eastern Botswana). Pollution by these metals was ... -
Assessment of rangelands around Molepolole village of Botswana to ascertain its potential to support free range beef cattle despite its long term use as a grazing area
(Scholink, 2019-10-14)In Botswana, cattle rearing can either be in farms or in communal grazing areas. In communal grazing areas, carrying capacities are never adhered to, hence degradation sometimes occurs. This negatively impact on the livestock ... -
Assessment of γ-radiation levels and associated dose rates from surface soils in the eastern part of Botswana
(INDERSCIENCE Publishers, 2014)This paper reports the γ-radiation levels of the naturally occurring 40K, 210Pb, 232Th and 226Ra and the anthropogenic 137Cs in the eastern part of Botswana so as to assess their possible dose impact to the members of the ... -
Atmospheric transfer and deposition mechanisms of 210Pb aerosols onto forest Soils
(Springer Verlag, 2009-09)Activities of 210Pb carrier aerosols in an age-graded Sitka spruce conifer, three deciduous (oak, lime and sycamore) foliage and in rain and throughfall samples have been measured during the period of 2001–2002. The 210Pb ... -
Cattle dung in aquatic habitats alters mosquito predatory biocontrol dynamics
(Elsevier, 2022-09)Anthropogenic land use changes influence ecosystem functioning and may alter trophic interactions. Intensification of free–range pastoral farming could promote degradation of aquatic habitats, with nutrient inputs adversely ... -
The challenges of Ilaje youth in combining education with artisanal fishing in Ondo State, Nigeria.
(Botswana University of Agriculture and Natural resources, 2013)The study examined how Ilajes in-school youth entrepreneurs combined their education with fishing activities in Ondo State. It examined their personal characteristics, period of involvement and educational activities. ... -
Changes in Health-related Parameters Associated with Sports Performance Enhancement Drugs.
(Thieme Gruppe, 2022-12-02)The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and fat-burning drugs during a 6-month competition preparation period. The ... -
Condensed tannins from Botswanan forage plants are effective priming agents of γδ T cells in ruminants.
(Elsevier, 2012-03-05)The potential impact of extracts from forage plants on y8 T cell activity in ruminants was evaluated using an in vitro immunoassay. This study investigated whether plant extracts could prime y8 T cells via up-regulation ... -
Correlations between Anthropometric Measurements and Sports Discipline Aptitude.
(MDPI, 2022-06-22)Background: Sports specialization is required for the advancement of elite-level skills of a competitor. Therefore, this study attempted to assess the applicability of anthropometric measurements for a tailored selection ... -
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
(HARD Publishing, 2010)Deposition rates of atmospheric particles were determined using previously published 210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils were 2.2±1.8 and 9±2 mm• s-1, respectively. ... -
Determinants of vegetation type patch dieback in a semi-arid area, Tutume Sub-District, Botswana
(Academic Journals, 2018-01-12)Patch dieback of Colophospermum mopane (Kirk ex Benth.) Kirk ex J. Léonard, which was attributed to drought, soil surface condition and soil chemistry has been reported in South Africa. In Botswana, dieback of C. mopane ... -
Determination of the aroma properties of Mustard seeds by SPME - GC-MS
