Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
(University of the Western Cape, 2005)Huge amounts of data are being collected as a result of the increased use of mobile telecommunications. Insight into information and knowledge derived from these databases can give operators a competitive edge in terms of ... -
Deciphering a potential cytoprotective role of novel heat shock responsive proteins using a proteomic approach
(University of the Western Cape, 2011)Myocardial infarction, commonly known as a heart attack, is a condition where the blood supply to the heart tissue is cut off, starving the tissue from oxygen and nutrient supply, with consequent lethal damage to the heart ... -
Defining the African green monkey (Chlorocebus Aethiops): expression behaviour of selected lipid metabolism genes in response to niacin
(University of Western Cape, 2012)In this century most major medical advances have resulted in part from research on animals and non-human primates such as the African green monkey and therefore often serve as a critical link between basic research and ... -
Degradation of bisphenol-a and 2-Nitrophenol by combined advanced oxidation technologies
(University of the Western Cape, 2015)Emerging micropollutants such as bisphenol-A and 2-nitrophenol present a great threat in drinking water due to their adverse effects. Most conventional technologies in water and wastewater treatment are not designed to ... -
The degradation of the endocrine disrupting chemical, bisphenol-A : a comparative study between fungal and bacterial laccases
(University of the Western Cape, 2015)The degradation of endocrine disrupting chemicals (EDCs) is a topic of high importance and one that research efforts are continually being focused on. These harmful chemicals are known to cause adverse health effects in ... -
Demitrios Tsafendas: race, madness and the archive
(University of the Western Cape, 2011)This thesis is concerned with the archival production on the life of Demitrios Tsafendas, the man who assassinated Hendrik Verwoerd on the 6 September 1966. Through an examination of three different archival registers: the ... -
Deposition and structural properties of silicon carbide thin films for solar cell applications.
(University of the Western Cape, 2014)The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell applications has been studied. The films were characterized for structural ... -
Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ... -
The depositional environment of Sandstone reservoirs, of wells within F-AH and F-AR field, offshore the Bredasdorp basin, South Africa
(University of the Western Cape, 2018)This study is located within the Bredasdorp Basin which is on the southern continental margin, offshore South Africa. The basin is located between Infanta and Agulhas arches and is a rift basin that is southeastern trending. ... -
The design and simulation of a new experimental set up to measure nuclear level lifetimes
(University of the Western Cape, 2016)Measurements of nuclear level lifetimes are an important aspect of experimental nuclear physics. Such measurements determine transition matrix elements for nuclear structure research and also provide the widths of relevant ... -
Design and synthesis of polycyclic amine derivatives for sigma receptor activity
(2013)New therapeutic strategies are needed for a diverse array of poorly understood neurological impairments. These include neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, and the psychiatric ... -
The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol
(University of Western Cape, 2014)A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing sensing platform signals. Three label-free ... -
Design, implementation and evaluation of a model for Service-learning in Pharmacy (SLIP) at a tertiary hospital
(University of the Western Cape, 2009)In recent years the focus of pharmacy practice has changed from being primarily 'drug-centred to' one which is 'patient-centred' (El-Awady et al., 2006, p. l ). Developments in pharmacy curricula worldwide are reflecting ... -

(2009)Background In recent years the focus of pharmacy practice has changed from being primarily ‘drugcentred to’ one which is ‘patient-centred’ (El-Awady et al., 2006, p.1). Developments in pharmacy curricula worldwide are ... -
The design, preparation and evaluation of Artemisia Afra and placebos in tea bag dosage form suitable for use in clinical trials
(University of the Western Cape, 2006)Artemisia Afra, a popular South African traditional herbal medicine is commonly administered as a tea infusion of the leaves. However, clinical trials proving it safety and efficacy are lacking mainly due to the absence ... -
Design, Synthesis and Evaluation of Indole Derivatives as Multifunctional Agents against Alzheimer's disease.
(University of the Western Cape, 2017)Alzheimer's disease (AD) is an age related neurodegenerative disorder characterised by progressive memory loss and cognitive impairment. It is one of several neurodegenerative disorders occurring as a result of a process ... -
Designing next generation high energy density lithium-ion battery with manganese orthosilicate-capped alumina nanofilm
(University of the Western Cape, 2015)In the wide search for advanced materials for next generation lithium-ion batteries, lithium manganese orthosilicate, Li₂MnSiO₄ is increasingly gaining attention as a potential cathode material by virtue of its ability to ... -
Detecting Galaxies in the Epoch of Reionization
(University of the Western Cape, 2017)The aim of this project was to develop a technique that allows us to measure the redshift of radio galaxies in the Epoch of Reionization. We achieved this by constructing a parameterization of the 21-cm absorption feature ... -
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 ... -
Detection of selective Tyrosinase inhibitors from some South African plant extracts of Lamiaceae family
