Synthesis and characterization of rhenium (vii) and rhuthenium (ii) dendritic catalysts: oxidative cleavage and epoxidation of alkenes
(2012)
Herein we report the successful synthesis of a class of stable and flexible Schiff-base chelators capable of coordinating both ruthenium (II) and rhenium (VII) and which would be catalytically active for oxo-transfer ...
Electrochemical characterization of platinum based catalysts for fuel cell applications
(University of the Western Cape, 2012)
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR),
overpotential, and methanol fuel cross over ...
Towards ensuring scalability, interoperability and efficient access control in a triple-domain grid-based environment
(2012)
The high rate of grid computing adoption, both in academe and industry, has posed
challenges regarding efficient access control, interoperability and scalability. Although several methods have been proposed to address ...
Mathematical modeling and analysis of HIV/AIDS control measures
(University of the Western Cape, 2012)
In this thesis, we investigate the HIV/AIDS epidemic in a population which experiences a significant flow of immigrants. We derive and analyse a math-
ematical model that describes the dynamics of HIV infection among the ...
Laccases from actinomycetes for lignocellulose degradation
(University of the Western Cape, 2012)
The purpose of this study shows that lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. ...
Effects of season and cohort on the haematology of the geometric tortoise Psammobates geometricus.
(University of the Western Cape, 2012)
The geometric tortoise is one of the world‟s rarest terrestrial tortoises and is endemic to the Southwestern Cape, South Africa. There has been cause for conservation concern for Psammobates geometricus, yet as is common ...
Development of a model to predict the cost of management of diabetes mellitus and its complications at Groote Schuur Hospital
(University of the Western Cape, 2012)
Diabetes mellitus places a substantial financial burden on the funder for treatment of this disease. This burden is compounded by the development of diabetes mellitus related complications. The cost of management of diabetes ...
Isolation and characterisation of a xylanase producing isolate from straw-based compost
(University of the Western Cape, 2012)
Lignocellulosic biomass, a waste component of the agricultural industry, is a promising source for use in bioethanol production. Due to a complex structure, the synergistic action of lignocellulosic enzymes is required to ...
Optimisation of a microfluidic device for the pre-concentration and size separation of cell free foetal DNA from maternal plasma by capillary electrophoresis
(University of the Western Cape, 2012)
The discovery of cell free foetal DNA (cffDNA) in 1997 allows for the combination of accuracy as well as non-invasiveness for prenatal diagnosis. This non-invasive genetic test requires only a maternal blood sample from ...
Electrodeposition of multi-valent metal oxides at 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid - carbon paste electrode
(University of the Western Cape, 2012)
A study on carbon paste electrode (CPE) materials containing 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [MOIM[Tƒ2N] – a hydrophobic room temperature ionic liquid (IL) - is reported. CPEs with (a) the ...
