On non-metric covering lemmas and extended Lebesgue-differentiation theorem
(Science Domain International;http://www.sciencedomain.org, 2015-03-28)
We give a non-metric version of the Besicovitch Covering Lemma and an extension of the Lebesgue-Differentiation Theorem into the setting of the integration theory of vector valued functions.
On natural characterizations of tensor integrability
(Science Domain International, http://www.sciencedomain.org/, 2015-05-04)
We revisit the deﬁnition of the tensor integrability introduced in , and prove some useful characterizations that provide a foundation for studying relevant properties to the integration theory. As applications, we ...
Free radical scavenging and antioxidant properties of a truffle, Kalaharituber pfeilii found in Kalahari deserts of Botswana
(Int.J.Bioassays, http://www.ijbio.com/index.php/ijb, 2015)
Natural anti-oxidants are the good source for scavenging excess of free radicals generated in the body after oxidative stress. The present study is aimed at in vitro evaluation of free radical scavenging potentials of two ...

(International Network for Natural Sciences (INNSPUB), http://www.innspub.net, 2015)
The current study evaluated the concentration and levels of pollution by heavy metals in soils around BCL Cu/Ni mine in Selebi-Phikwe, Botswana. Soil samples were collected from four different locations namely 2.5 km east, ...
Development of Sitotroga cerealella (Olivier) on certain cereal grains in Botswana
(Applied Zoologists Research Association (AZRA), http://www.azra-india.com/journal.html, 2015)
The development of Sitotroga cerealella (Olivier) was studied on maize (kalahari early pearl and yellow maize varieties), sorghum (segaolane and sephala varieties) and millet (serere 6A and legakwe varieties), under ambient ...
Absorption of Microwaves in Low Intensity Eucalyptus Litter Fire
(Scientific Research Publishing Inc., http://www.scirp.org, 2015)
A fuel bed was constructed where various vegetation species could be used as combustion fuel. The fuel bed was equipped with a thermocouple to measure fire temperature and a two-port automatic network analyser to measure ...
Controlled Texturing of Aluminum Sheet for Solar Energy Applications
(Scientific Research Publishing Inc., http://www.scirp.org/, 2015)
Aluminum sheets were polished to reduce ruggedness and then textured in varying acid-ethanol concentration etchant to form pores. The textured surface was characterized structurally by using X-ray diffraction (XRD) which ...
Making markets work for the poor (M4P) approach and smallholder irrigation farming
(Omics Publishing Group; www.omicsgroup.org, 2015)
The aim of this article is to show what M4P is, how it came into being and how it has been used to guide intervention in different context and to weigh the extent to which it can be used to guide the study and interventions ...
