Identification of novel cold-adapted nitrilase superfamily enzymes
(2009)In bacteria, nitrile hydratases and enzymes of nitrilase and signature amidase superfamilies hydrolyse nitriles and amides to their corresponding carboxylic acids releasing ammonia. Bacteria expressing these enzymes are ... -
In silico investigation of glossina morsitans promoters
(University of the Western Cape, 2013)Tsetse flies (Glossina spp) are the biological vectors for Trypanosomes, the causative magents of Human African Trypanosomiasis (HAT). HAT is a debilitating disease that continues to present a major public health problem ... -
The influence of diversity and the educational climate in shaping clinical competence of oral health students
(2013)High attrition, low retention and low throughput are major problems facing South African higher education institutions. These problems have been attributed to student under-preparedness as a result of the legacy of apartheid ... -
Lifetime measurements of excited nuclei through modern nuclear spectroscopy
(University of Western Cape, 2021)The progressive development of scintillator detectors has made it possible to perform direct electronic lifetime determination up to a few hundred nanoseconds. The 2" by 2" LaBr3:Ce detectors provide a combination of ... -

Low temperature tungsten trioxide nano/micro-systems for applications in gas sensing and electrochromism
(2013)In this work we primarily set out to investigate the technique of Aqueous Chemical Growth as a means of producing WO3 thin films that find applications in gas sensing and electrochromism. For the first time we demonstrated ... -
Male identified same-sex sexual fetish in South Africa: (re)defining sexual relations between people and things
(2010)Historical ethnographic and early psychoanalytic epistemologies on 'fetishism' focus primarily on the fetish 'object', whereby the subject of 'fetish practices' was identified, pathologised and/or socioculturally invalidated ... -

(2013)The thesis examines the characteristics of land tenure among African families with freehold title who trace their relationship to the land to their forebears who first acquired title in the mid-nineteenth century. The ... -
A model for obtaining parental informed consent for HIV clinical trials research with pediatric patients
(2013)All research involving human subjects should be conducted in accordance to the general ethical principles of autonomy or respect for persons, beneficence and justice. Competent adults can exercise their autonomy and can ... -
Modelling of reliable service based operations support system (MORSBOSS)
(2008)The underlying theme of this thesis is identification, classification, detection and prediction of cellular network faults using state of the art technologies, methods and algorithms. -
Multicomponent catalysts for methanol electro-oxidation processes synthesized using organometallic chemical vapourde position technique
(University of the Western Cape, 2011)In this study, the OMCVD method is demonstrated as a powerful, fast, economic and environmental friendly method to produce a set of PGMelectrocatalysts with different supports, metal content and metal alloys in one step ... -
Poverty and access to health care in Ghana: the challenge of bridging the equity gap with health insurance
(University of the Western Cape, 2014)This study addresses the issue of the low participation in or enrolment of the poor in Ghana’s National Health Insurance Scheme (NHIS). The low enrolment of the poor in the NHIS is attributed to the difficulty in identifying ... -

The relative impact of an argumentation-based instructional intervention programme on grade 10 learners’ conceptions of lightning and thunder
(2012)The basic premise of this study was that when a learner is confronted with two contradictory explanations of the same phenomenon, there is cognitive dissonance in the learner as the learner tries to determine which of the ... -
Reservoir quality, structural architecture, fluid evolution and their controls on reservoir performance in block 9, F-O gas field, Bredasdorp Basin, offshore South Africa
(University of the Western Cape, 2012)The use of integrated approach to evaluate the quality of reservoir rocks is increasingly becoming vital in petroleum geoscience. This approach was employed to unravel the reason for the erratic reservoir quality of ... -
Rock art in the Northern Cape: the implications of variability in engravings and paintings relative to issues of social context and change in the precolonial past
(2012)This thesis follows and builds upon a previous study at the rock engraving site of Driekopseiland (Morris 2002). The earlier findings are here contrasted with another site in the area, namely Wildebeest Kuil, as a means ... -
Search for low spin collective structures in 158Er and 159Er
(2013)Lying in a rapidly-changing transitional region between nuclei that may behave as spherical vibrators (N ≤ 88) or good rotors (N ≥ 92), the N = 90 isotones present a unique testing ground where new nuclear collective ... -
Socio-economic position, oral pain and oral health-related quality of life among South African adults
(University of the Western Cape, 2014)Validation of the OHIP-14 for a South African adult population using CFA resulted in a 12-item scale (OHIP-12) with excellent reliability (α =0.94), but the structural pathway varied across the socio-economic groups. The ... -
