Heterocycle carbonyl pyrazolyl palladium(II) complexes :synthesis, ethylene oligomerisation and polymerisation catalysis
(University of the Western Cape, 2004)
Reactions of furan, thiophene and alkyl carbonyl chlorides with Unsubstituted and substituted pyrazoles produced the desired pyrazolyl ligands, [R2pyrazole-CO-R/] (R= H, Me, tBu, Ph, R/ = furan, thiophene, Me or tBu) in ...
Species-level phylogenetic reconstruction of the African cycad genus Encephalartos (Zamiaceae)
(University of the Western Cape, 2007)
This thesis explores species-level phylogenetic relationships of the African cycad genus
Encephalartos, which is one of the eleven genera of cycads. The genus is confined to
Africa and comprises approximately 65 species, ...
Preparation and characterization of highly active nano pt/c electrocatalyst for proton exchange membrane fuel cell
(University of the Western Cape, 2006)
Catalysts play an essential role in nearly every chemical production process. Platinum supported on high surface area carbon substrates (Pt/C) is one of the promising candidates as an electrocatalyst in low temperature ...
Detection of positive selection resulting from Nevirapine treatment in longitudinal HIV-1 reverse transcriptase sequences
(University of the Western Cape, 2006)
Nevirapine (NVP) is a cheap anti-retroviral drug used in poor countries worldwide, administered to pregnant women at the onset of labour to inhibit HIV enzyme reverse transcriptase. Viruses which may get transmitted to ...
Assessment controls on reservoir performance and the affects of granulation seam mechanics in the Bredasdorp Basin, South Africa
(University of the Western Cape, 2006)
The Bredasdorp Basin is one of the largest hydrocarbon producing blocks within Southern Africa. The E-M field is situated approximate 50 km west from the FA platform and was brought into commission due to the potential ...
Stakeholder participation in the establishment of the Berg Catchment Management Agency, South Africa
(University of the Western Cape, 2007)
Enacted in 1998, the New South African Water Act has introduced a new approach to water resource management, founded on the principle of decentralization of the management of water resources to regional and local levels ...
Electrochemical impedance modelling of the reactivities of dendrimeric poly(propylene imine) DNA nanobiosensors
(University of the Western Cape, 2008)
In this thesis, I present the electrochemical studies of three dendrimeric polypropylene imine (PPI) nanomaterials and their applications as a platform in the development of a novel label free DNA nanobiosensor based on ...
Three-dimensional structure of a type III glutamine synthetase by single particle reconstruction
(University of the Western Cape, 2007)
This study represents the first structural investigation of any type III glutamine synthetase (GS). The GS, GlnA, from the medically important opportunistic human pathogen Bacteroides fragilis was studied with a view to ...
Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)
In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ...
Fitting extreme value distributions to the Zambezi River flood water levels recorded at Katima Mulilo in Namibia (1965-2003)
(University of the Western Cape, 2005)
This study sought to identify and fit the appropriate extreme value distribution to
flood data, using the method of maximum likelihood. To examine the uncertainty of
the estimated parameters and evaluate the goodness of ...
