Performance evaluation of commonly used oil ram press machines
(CIGR Journal http://www.cigrjournal.org/, 2007)The ram-press technology for oil expression has received a lot of attention in many African countries during the last two decades. The technology is based on manually operated mechanical presses, which employ a slider-crank ... -
Lessons and challenges encountered in the implementation of solar energy – the case of Botswana
(Bentham Open http://www.bentham-open.org, 2009-01-01)A number of photovoltaic pilot projects have been started in Botswana since 1990. The first photovoltaic project was Manyana PV project which started in 1992. The Japanese International Cooperation Agency (JICA) PV solar ... -
Acceptance of blackboard technology by mechanical engineering students at the University of Botswana
(Tempus Publications, 2009)Technology-based teaching and learning is entering academic life at an amazing rate. It comes whether invited or not. Students and lecturers are confronted with new technologies. There are new teaching methods to accompany ... -
Investigating the pumping process of a resonance-vibrating pump for medium-depth boreholes
(Research in Agricultural Engineering http://journals.uzpi.cz/web/RAE.htm, 2007)This paper deals with the pumping process of a resonance-vibrating pump, which utilizes the resonance vibrations of one degree-of-freedom oscillating system. The pump is powered by a mechanical shaker consisting of ... -

Improvement of AC electronmagnet performance
(University of Botswana, 1999)Electromagnets are essentials for the operation of relays, contactors and other electromagnetic apparatus and take part in driving control and protective circuits of industrial processes and power systems. Performance of ... -
Model for cover cracking of RC beams due to partial surface steel corrosion
(Elsevier http://www.elsevier.com/locate/conbuildmat, 2011)Cracking of the cover concrete due to steel corrosion is considered by many researchers to indicate the end-of-service life of corrosion-affected reinforced concrete (RC) structures. Numerous models have been developed ... -
Finite elements in practice: a review of engineerin's most versatile method
(University of Botswana, 1999)Advantages of using Finite Element Method (FEM)in structural engineering practice are presented in this paper.A brief description of the method is given with the aim to illustrate the rich solid mathematical basis that ... -
A survey of possible household participation patterns in solid waste source separation in Gaborone
(University of Botswana, 2006)Public support for source separation schemes in developing countries is still subject to continuing debate and limited work has been directed at understanding its manifestations. The purpose of this survey was to assess ... -
Cascade system reliability with Rayleigh Distribution
(University of Botswana, 1999)The stress-attention in cascade reliability has been studied when both stess and strength follow Rayleigh distribution. The expression for the relaibility R(n), for a system survive with the first (n-1) components failed ... -
Influence of corrosion crack patterns on the rate of crack widening of RC beams
(Elsevier http://www.elsevier.com/locate/conbuiltmat, 2011)Corrosion crack widths are often used by structural engineers in the field to predict level of steel corrosion as well as residual load-bearing capacities of corroding RC structures. This paper presents further work on ... -
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 ... -
