The effect of insulin, leptin and inflammatory cytokines on reproductive health and hypogonadism in males diagnosed with the metabolic syndrome
(2013)The metabolic syndrome (MetS) is a collection of various metabolic, hormonal and immunological risk factors that cluster together, closely related to poorly understood phenomena such a hyperinsulinaemia (insulin resistance), ... -
Efficacy and safety of various tooth-whitening products, with special reference to the three dimensional colour space (L*a*b*) measurements and the microhardness tests
(University of the Western Cape, 2011)Tooth-whitening or tooth-bleaching has become an integral part of modern dental practice. Today, a large number of whitening products are available on the market which are commonly categorized into dentist-supervised home ... -
Electropolymerization and electrochromism of poly(4,7-dithien-2-yl-2,1,3-benzothiadiazole) and its copolymer with 3-methoxythiophene in ionic liquids
(2013)This thesis is based on the study of electropolymerization and electrochromism of poly(4,7- dithien-2-yl-2,1,3-benzothiadiazole) (P(DTBT) and its copolymer with 3-methoxythiophene (MOT) in imidazolium ionic liquids (ILs) ... -
An exploration of the electrophysiological properties and ion transport across the isolated perfused seminiferous tubule of the rat
(UWC, 1999)A knowledge ofthe transport of ions is fundamental to the understanding ofthe 'bloodtestis' barrier and the transport of fluid across the seminiferous tubule. This is the first study that has investigated the isolated ... -
Exploration of the games of Malepa and Morabaraba in South African secondary school mathematics education
(University of the Western Cape, 2000)This study is based on the Exploration of the Games of Malepa and Morabaraba in South African Secondary School Mathematics Education . It explores culturally specific games through a qualitative research methodology that ... -
Extant benthic Foraminifera from two bays along the SW coast of South Africa, with a comment about their use as indicators of pollution
(University of the Western Cape, 2010)The results of the multivariate analyses suggest that most of the variation in the composition of the samples was of an intra-sample nature, illustrating large scale patchiness in foraminiferal distribution. There were, ... -
Fitted numerical methods to solve di erential models describing unsteady magneto-hydrodynamic ow
(2013)In this thesis, we consider some nonlinear di erential models that govern unsteady magneto-hydrodynamic convective ow and mass transfer of viscous, incompressible, electrically conducting uid past a porous plate ... -
A hierarchical modelling approach to identify factors associated with the uptake of HIV counselling and testing, maternal health services, and prevention of mother to child HIV transmission programme services among post-partum women in Ethiopia
(2013)The HIV/AIDS epidemic remains an unbeaten challenge that affects all parts of the global population. Since the identification of the epidemic in the early 1980s, nearly 58 million people have become infected with the ... -
A history of the organizational development of the seventh-day adventist church amongst the coloured community in South Africa 1887-1997
(2010)The Seventh-day Adventist Church in South Africa was planted towards the end of the 19th century. Within less than forty years after its inception, a separate Coloured department developed. This was not to be the last ... -
Homelessness and Violence: Freud, Fanon and Foucault and the shadow of the Afrikan sex worker
(University of the Western Cape, 2012)In this thesis, I will argue that one of the ways to think about the concept of homelessness and its relationship to violence is to trace the concept as it emerges in key theoretical texts of critical intellectuals who ... -
Hydraulic properties of the table mountain group (TMG) aquifers
(2008)Research findings in current study provide a new insight into the fractured rock aquifers in the TMG area. Some of the results will have wide implications on the groundwater management and forms a solid basis the further ... -
Identification and characterisation of the role of endozepine in apoptosis induced by ceramide
(University of the Western Cape, 2003)Apoptosis is a form of programmed cell death and is required for the normal development, tissue homeostasis and survival of organisms. The identification of mutations that can lead to alterations in cell death not only ... -
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 ... -
