Environmental chemistry and mineralogy of particulate air matter around Selebi Phikwe nickel–copper plant, Botswana
(Elsevier www.elsevier.com/locate/mineng, 2004)
This study aimed at chemically and mineralogically characterizing whole particulate air matter (PAM) occurring at the Selebi
Phikwe nickel–copper (Ni–Cu) area in Botswana, and postulating its possible environmental ...
Homotopy Lie Algebra of Spaces for Hyperbolic Coformal 2-Cones
(International Press; http://www.intlpress.com/HHA/, 2004)
In this paper, we show that the rational homotopy Lie algebra
of classifying spaces for certain types of hyperbolic coformal
2-cones is not nilpotent.
Nitrogen cycling in the soil–plant system along a precipitation gradient in the Kalahari sands
(Blackwell Publishing, 2004-01-01)
Nitrogen (N) cycling was analyzed in the Kalahari region of southern Africa, where a
strong precipitation gradient (from 978 to 230mm mean annual precipitation) is the main
variable affecting vegetation. The region is ...
Assessment of groundwater pollution vulnerability and modelling of the Kanye Wellfield in SE Botswana—a GIS approach
(Elsevier Science Ltd, http://www.elsevier.com/locate/pce, 2004)
Botswana is a semi-arid country with limited recharge to groundwater resources. Groundwater however is a major source of
water for domestic, industrial and agricultural uses. There is therefore the need to ensure that the ...
Trace enrichment of metal ions in aquatic environments by Saccharomyces cerevisiae
(Elsevier; www.elsevier.com/locate/talanta, 2004)
[Please note that chemical formulae do not display correctly in this abstract]. Sorption properties of baker's yeast cells, characterised as Saccharomyces cerevisiae were evaluated for trace enrichment of metal ions: Cd2+, ...
