The level of recycling operations in Botswana
(University of Botswana, www.ub.bw, 2004)This paper describes a case study that evaluated the level of recycling operations in Botswana. Recycling operations are now recommended as effective waste management strategies for reducing the amount of municipal solid ... -
Lie group classification of the generalized Lane-Emden equation
(Elsevier http://dx.doi.org/10.1016/j.amc.2009.01.008, 2009)We carry out the Lie group classification of the generalized Lane–Emden equation xu00 þ nu0 þ xHðuÞ ¼ 0, which has many applications in mathematical physics and astrophysics. We show that the equation admits a three-dimensional ... -
Low flush water closets in buildings and their effects in the drainage systems
(University of Botswana, 1999)Water scarcity in arid and semi-arid countries such as Botswana; call for judicious planning and economic use. In this connection many water saving components and appliances have been devised. One such system for example ... -
Management of waste oil in Botswana and the possibilities of energy recovery from waste oil
(University of Botswana, 1998)Since independence, the economy of Botswana has been undergoing a rapid transition from one in which the majority of the people depend on traditional agriculture and pastoralism to one in which formal sector employment ... -
