Some implications of driver training for road accidents in Gaborone
(Elsevier Science Ltd, http://journals.elsevier.com/00014575/accident-analysis-and-prevention/, 1995)In many African countries, including Botswana, the driving schools and instruction given to pupils are uncontrolled. Thus, this paper presents the results of an investigation into the level of professional training offered ... -
Energy and exergy analyses of energy consumptions in the industrial sector in South Africa
(Elsevier Science Ltd, http://www.elsevier.com/locate/apenergy, 2007)The energy-utilization over a 10-year period (1994–2003) has been analysed for the South African industrial sector, which consumes more primary energy than any other sector of the economy. Four principal sub-sectors, ... -
Theoritical analysis of an offset single-stroke ram press for sunflower oil extraction
(International Symposium on Theory of Machines and Mechanisms (IFToMM), 2001)The single-stroke ram press machine is widely used for sunflower oil extraction in African countries.
