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.
Identification of Cu and Ni indicator plants from mineralised locations in Botswana
(Elsevier www.elsevier.com/locate/jgeoexp, 2005)
Plant species that accumulate high levels of metals in proportion to the metal content in the soil are of considerable interest
in biogeochemical and biogeobotanical prospecting. This study was aimed at investigating ...
Characterization of agriculture-related land degradation in eastern and western parts of Botswana
(University of Botswana, http://www.ub.bw, 2005-04)
A study was carried out during 1998-2001 with the objective of, firstly, assessing the impact of cultivation on soil quality, and secondly, evaluating the effects of human and animal activities on soil erosion and range ...
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 ...
Stochastic estimator-based wireless traffic control schemes
(Science Publications, http://www.scipub.org/scipub/c4p.php?j_id=JCS, 2007)
Recent works on Available Bit Rate (ABR) traffic control have generated efficient control schemes for ABR traffic on Asynchronous Transfer Mode (ATM) network. This study examines the
improved performance envisaged if these ...
Prevalence, antimicrobial resistance profiles of Listeria monocytognes from various foods in Gaborone, Botswana
(Academic Journals, http://www.academicjournals.org/AJB, 2009)
Listeria monocytogenes is known to cause epidemic and sporadic cases of listeriosis. The present study investigated the occurrence, antibiograms and molecular serotypes of the organism in various retail outlets in Gaborone, ...
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 ...
Improving the quality of service guarantee in an Asynchronous Transfer Mode (ATM) Network
(Science Publications, http://www.scipub.org/scipub/c4p.php?j_id=JCS, 2007)
This study presents a technique for improving the quality of service (QoS) guarantee in an ATM network. In the proposed model, it was assumed that high priority traffic have been allocated a switch resource to guarantee a ...
Use of neutron probe and tensiometry techniques in determining water characteristics of the two soil types
(University of Botswana, Faculty of engineering and technology, http://www.ajol.info/index.php/bjt/index, 2008)
Characterisation of soil water, in particular water flow dynamics is fundamental in assessing the environmental
implications to soil management. Soil water characterisation was assessed by measuring soil water content and ...
Comparative assessment of water infiltration of soils under different tillage systems in eastern Botswana
(Elsevier Science Ltd, http://www.elsevier.com/locate/pce, 2009)
Water infiltration is an important component of water balance for improving crop production potential in
dryland soil tillage systems in Botswana, particularly in the eastern region. Hardsetting soils common in arable ...
