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 ...
Performance and emission characteristics of tylosema esculentum biodiesel in a diesel engine: an experimental investigation
(David Publishing, http://www.davidpublishing.com/, 2014-01-31)
Biodiesel derived from indigenous feed stocks such as Tylosema esculentum kernel oil is deemed a feasible alternative to petroleum diesel for the diesel engine. This paper presents results of investigation of performance ...
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 ...
Assessment of solar-coal hybrid electricity power generating systems
(David Publishing, http://www.davidpublishing.com/, 2012-01)
Botswana currently depends on electricity generated from coal-based power plant or electricity supplied from the border in South Africa. The country has good reserves of coal and the solar radiation is sufficiently high ...
Experimental assessment of locomotive brake blocks-case studies of Botswana Railways
(University of Botswana, www.ub.bw, 2011)
The brake blocks employed on Botswana Railways locomotives have been found to fail frequently resulting in increased maintenance and operational costs. The paper presents the metallurgical and mechanical properties of two ...
Cyclic plasticity of polycrystalline nickel under axial–torsional loading
(Elsevier, www.elsevier.com, 2010)
The axial–torsional cyclic deformation behavior of polycrystalline nickel was investigated by performing
fully reversed plastic strain amplitude controlled fatigue experiments at effective plastic strain amplitudes
ranging ...
Study on impact strength of untreated and alkali treated napier grass fiber strands reinforced epoxy composites
(ACE Publications, https://theacepublications.com, 2013)
Napier grass fiber strands were extracted using the combined mechanical and water retting process. The extracted fiber strands were treated with various proportions (5, 10 and 15% w/v) of NaOH solution to improve their ...
