Chemical extraction and property analyses of marula nut oil for biodiesel production
(Scientific Research Publishing, http://www.scirp.org/, 2011-07)
To identify and develop alternative and renewable sources of fuel for the transport sector is a present challenge for engineers and researchers. This work was carried out to assess yield of marula (Sclero carrya/birrea) ...
Blending cooking oil biodiesel with petroleum diesel: a comparative performance test on a variable ic engine
(Scientific Research Publishing, http://www.scirp.org/, 2011-05)
Research in biodiesel production has been motivated by several reasons including consistant increase in prices of pe-troleum diesel, environmental advantages, security of fuel supply, and employment creation. This paper ...
Biodiesel for sustainable energy provision in developing countries
(Scientific Research Publishing, http://www.scirp.org/, 2011-09)
Consumption of fossil fuel resources has been growing over the years and it is the kernel of economic development. However combustion which takes place principally in automobiles, power generation and industrial plants ...
Marula oil and petrodiesel: a comparative performance analysis on a variable compression ignition engine
(Scientific Research Publishing, http://www.scirp.org/, 2011-07)
The quest for biofuel production and use in Botswana is driven by factors including volatile oil prices, need for fuel security, potential for job creation, potential reduction in greenhouse gas emissions, and economic ...
Assessment of potential for biodiesel feedstock of selected wild plant oils indigenous to Botswana
(Canadian Center of Science and Education (CCSE), www.ccsenet.org/eer, 2011-12)
Biodiesel is attracting increasing attention worldwide as a blending component or a direct replacement of petroleum diesel fuel in transport sector.vThe challenge to scientists and engineers is to identify appropriate ...
Predicting the flexural behaviour of masonry wall panels: a review of current methods
(Faculty of Engineering and Technology, University of Botswana, www.ub.bw, 2011-04)
The paper aims to compare predictions by different methods of analysis of the lateral load capacity of unreinforced masonry walls, and to determine whether a relationship can be drawn between theory and experiments. Several ...
The need to assess effect of aggregates on performance of concrete in Botswana
(Faculty of Engineering and Technology, University of Botswana, www.ub.bw, 2011-04)
Concrete is the widely used construction material worldwide. Therefore, for structural safety as well as to provide economic design, it is essential to understand well, its performance. Whilst in most developed countries ...
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 ...
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 ...
Exploring the possibility of using earned value analysis during the construction phase of a building project
(Faculty of Engineering and Technology, University of Botswana, www.ub.bw, 2011-04)
To deliver project effectively is of paramount importance because most of the world population depend on services delivered by projects. Reports from various countries around the world, including Botswana, still indicate ...
