HIV Subtype C Diversity: Analysis of the Relationship of Sequence Diversity to Proposed Epitope Locations
(University of the Western Cape, 2002)Southern Africa is facing one of the most serious HIV epidemics. This project contributes to the HIVNET, Network for Prevention Trials cohort for vaccine development. HIV's biology and rapid mutation rate have made vaccine ... -
Holarrhena floribunda leaves as a potential source of bioactive anticancer compounds
(University of the Western Cape, 2014)Cancer is one of the leading causes of morbidity and mortality in developed and developing nations. It is estimated that 86% of new cases and 64% of death due to cancer are from Africa and 13.1 million deaths are estimated ... -
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 ... -
Homogeneity of nanophase electrocatalysts supported on mesoporous materials
(University of the Western Cape, 2006) -
Homology modelling and characterization of three-dimensional (3d) protein structures of selected variants of cyp3a4
(University of the Western Cape, 2022)The efficacy and toxicity of several drugs and prodrugs are influenced by the interindividual genetic variations in drug-metabolising enzymes. Cytochrome P450 enzymes constitute the major metabolising enzymes in humans. ... -
Hot-wire chemical vapor deposition of silicon nitride thin films
(2013)Amorphous silicon nitride (a-SiN:H) thin films has a multitude of applications, stemming from the tunability of the material properties. Plasma enhanced chemical vapour deposition (PECVD) is the industrial workhorse for ... -
Hot-wire chemical vapour deposition of carbon Nanotubes
(University of the Western Cape, 2006)In this study we report on the effect of the deposition parameters on the morphology and structural properties of CNTs, synthesized by means of the hot-wire chemical vapour deposition technique. SEM, Raman and XRD results ... -
Hot-wire chemical vapour deposition of nanocrystalline silicon and silicon nitride : growth mechanisms and filament stability
(University of the Western Cape, 2012)Nanocrystalline silicon (nc-Si:H) is an interesting type of silicon with superior electrical properties that are more stable compared to amorphous silicon (a-Si:H). Silicon nitride (SiNₓ) thin films are currently the ... -
Household access to water and willingness to pay in South Africa: evidence from the 2007 General Household Survey
(University of the Western Cape, 2011)This study assesses the present level of household water access and the willingness to pay in South Africa. Although the general literature informs that progress has been made in positing South Africa above the levels found ... -
How a population and housing census can be conducted after an epidemic, pandemic or a national crisis?
(University of the Western Cape, 2022)The population and housing census is the entire official process of enumeration of a country's residents and houses at a specified time. This process includes planning, demographic data collection, compilation, evaluation, ... -
How do teachers and learners navigate the terrain of ecology and what are the associated conceptual understanding?
(2011)This thesis relates the teaching of ecology in schools to the requirements of the National Curriculum Statements, Grades R-9 and Grades 10-12, for Natural and Life Sciences. It examines the conceptual understanding of the ... -

Human testis angiotensin-converting enzyme: crystal structure of a glycosylation mutant and investigation of a putative hinge-mechanism by normal mode analysis
(University of the Western Cape, 2004)Human angiotensin-converting enzyme (ACE) is a key enzyme in the regulation of blood pressure via the renin-angiotensin and kallikrein-kinin systems. A number of orally active drugs have been developed over the years ... -
Hybrid lead halide perovskite thin films and solar cells by chemical vapour deposition
(University of the Western Cape, 2021)The organic-inorganic hybrid perovskites such as methyl ammonium lead iodide (MAPbI3) or mixed halide MAPbI3-xClx (x is usually very small) have emerged as an interesting class of semiconductor materials for their application ... -
Hybrid molecules as inhibitors of the monoamine oxidases and caspase 3 for neurodegenerative disorders
(University of the Western Cape, 2016)Neurodegenerative diseases are multifactorial in nature, and taking the complex nature of these disorders into consideration, multi-target directed ligands may present as better options to treat these disorders than the ... -
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 ... -

Hydraulic properties of the Table Mountain group (TMG) aquifers
(University of the Western Cape, 2006)The Table Mountain Group (TMG), located at the southmost cape of African Continent, is one out of three major regional aquifer systems in South Africa, which has a potential of bulk water supply to meet the requirements ... -
Hydraulic properties of the vadose zone at two typical sites in the Western Cape for the assessment of groundwater vulnerabilitv to pollution
(University of the Western Cape, 2007)Aquifer vulnerability assessment is increasingly becoming a very significant basis in order to fulfil the water demands in South Africa. Knowledge of soil hydraulic properties that consists of the soil water retention and ... -
