Health seeking behaviours in South Africa: a household perspective using the general households survey of 2007
(University of the Western Cape, 2010)This study is aimed at empirically examining health seeking behaviours in terms of illness response on household level at South Africa using 2007 General Household Survey and other relevant secondary sources. It provides ... -
Heavy and precious metal toxicity evaluation using a horseradish peroxidase immobilised biosensor
(University of the Western Cape, 2012)Environmental pollution is always the hottest topic in public conversation and one of the most concerned aspects of human health. The thin film sputtered microelectrode devices have been developed to improve the quality ... -
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 ... -
Heteroscleromorph demosponge taxonomy and diversity of the Amathole region (Eastern Cape, South Africa)
(University of Western Cape, 2022)Sponges are functionally important and ubiquitous components of the global marine benthos. South Africa accounts for roughly 4% of the global marine sponge diversity, comprising 374 described species and seven varieties/forms, ... -
HI intensity mapping: Impact of primary beam effects
(University of the Western Cape, 2023)Neutral hydrogen (HI) intensity mapping surveys with upcoming and future radio telescopes such as the MeerKAT, a precursor to the Square Kilometre Array Observatory (SKAO) MID telescope, have great potential for constraining ... -
An hi study of the nearby dwarf galaxy ic 4710
(University of Western Cape, 2021)This work aims to study the dark matter content of the nearby (7.38 Mpc) dwarf galaxy IC 4710 using the HI line observations from the Australia Telescope Compact Array (ATCA). We produce the rst interferometric maps of ... -
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 ... -
High Accuracy Fitted Operator Methods for Solving Interior Layer Problems
(University of the Western Cape, 2020)Fitted operator finite difference methods (FOFDMs) for singularly perturbed problems have been explored for the last three decades. The construction of these numerical schemes is based on introducing a fitting factor ... -
High performance computing and algorithm development: application of dataset development to algorithm parameterization
(University of the Western Cape, 2006)A number of technologies exist that captures data from biological systems. In addition, several computational tools, which aim to organize the data resulting from these technologies, have been created. The ability of these ... -
High resolution gamma-spectroscopy of environmental samples
(University of the Western Cape, 2019)In this study, a comparison has been made between the available commercial software package Genie 2000 developed by Canberra and Virtual Gamma Spectroscopy Laboratory (VGSL) developed by the Radionuclide Development Unit ... -
High-grade metamorphism, anatexis and deformation of metasedimentary rocks from the Kamiesberg Group near Kliprand, Southern Bushmanland Domain, Namaqua Metamorphic Province
(University of the Western Cape, 2022)Migmatitic metapelites of the Kamiesberg Group are distributed throughout the central Bushmanland Domain (Namaqua Metamorphic Province) which is otherwise dominated by felsic gneisses. This study focusses on an outcrop ... -
Higher order numerical methods for singular perturbation problems
(University of the Western Cape, 2009)In recent years, there has been a great interest towards the higher order numerical methods for singularly perturbed problems. As compared to their lower order counterparts, they provide better accuracy with fewer mesh ... -
Highly selective mesoporous sorbents for mercury removal from industrial wastewater
(University of the Western Cape, 2011)The results of this study show that novel mesoporous carbons were obtained as inverse replica of SBA-15, HMS and MCM-41 silica templates, with a large pore diameter (2-4 nm), a BET surface area of 1867, 874 and 910 m2g–1 ... -
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 ... -
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. HIVÂ’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 ... -
