Thermal analysis and annealing temperature dependence of electrical properties in Sn10Sb20Se70 glassy semiconductor
(Springer Netherlands, 2008)The melt-quenched Sn10Sb20Se70 sample in the bulk form was used to prepare films on well-cleaned glass substrates by thermal evaporation method. The activation energy for glass transition (apparent) and crystallization has ... -
Effect of annealing on the structural, optical and electrical properties of ITO films by RF sputtering under low vacuum level
(Elsevier Ltd, 2008)Indium tin oxide (ITO) thin films were prepared by RF sputtering of ceramic ITO target in pure argon atmosphere at a high base pressure of 3 10 4mbar without substrate heating and oxygen admittance. The use of pure argon ... -
Screen integrable lightlike hypersurfacesof indefinite sasakian manifolds
(Birkhäuser Basel. http://www.springerlink.com/content/110963/?p=c42ba01ff0bd482b81a3ebdf3b649c9a&pi=0, 2009)We investigate lightlike hypersurfaces of indefinite Sasakian manifolds, tangent to the structure vector field and whose screen distribution is integrable. We prove some results on parallel vector fields and on a leaf ... -
English language and gender influences on the prediction of junior certificate perfomance among students in Botswana
(African Educational Research Network. http://www.ncsu.edu, 2008-06)The poor and deteriorating overall performance in Botswana junior school certificate (JSC) examination is a problem that tends to defeat all efforts at finding a solution to it. Language has been found to be a powerful ... -
Community empowerment in Botswana: the practitioners' perspective
(South African Association of Family Ecology and Consumer Sciences (SAAFECS). http://ajol.info/index.php/jfecs/index, 2010)The term empowerment has become a buzz word used by development organisations and government sectors to make development programmes sound technically correct. These programmes are often the cause of the poor becoming ... -
Gender mainstreaming at the University of Botswana: a content analysis of UB newsletter
