Characterising the Prevalence and Mode of CXCR4 Usage in HIV-1 Group M Subtype C
(University of the Western Cape, 2013)Determination of CXCR4-usage patterns is essential in establishing suitability of CCR5 antagonist prescription in HIV-1 infected individuals to prevent treatment failure. Previous studies have suggested a switch ... -
The characteristics of an effective nonprofit organisation: A critical analysis
(University of the Western Cape, 2007)This thesis presents a model of the characteristics of an effective nonprofit organisation and a practical tool to evaluate the extent to which nonprofit organisations comply with these characteristics. As part of identifying ... -
Characterization and chemical speciation modelling of saline effluents at Sasol Synthetic Fuels Complex-Secunda and Tukuta power station
(University of the Western Cape, 2009)The study shows conclusively that brine composition and concentration is highly variable at these South African power utilities and processes such as RO, contact with ash and CO2 ingress can have an impact upon the overall ... -
Characterization and Chemical Speciation Modelling of Saline Effluents at Sasol Synthetic Fuels Complex-Secunda and Tutuka Power Station
(University of the Western Cape, 2009)Chemical speciation and the evaluation of species distribution is the key to understanding the potential of brines to form scale or corrode the water circuit as well as the potential of mobility and release trends of the ... -
Characterization and engineering of Bacillus megaterium AS-35, for use in biodegradation of processed olive wastewater
(University of Western Cape, 2005)The popularization and health benefits associated with the "Mediterranean diet" saw a world wide increase in the production and consumption of processed olives and olive oil. During the brining of table olives large ... -
Characterization of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase under salt stress
(2012)The production of reactive oxygen species (ROS) is prominent in all aerobic metabolisms including plants. For this reason, the redox homeostasis of the production and scavenging of these intermediates is imperative for ... -
Characterization of ATP-binding cassette drug transporters and their role in breast cancer treatment using in silico approach
(University of the Western Cape, 2019)Breast cancer is the most common cancer in women worldwide, and is the second most common cancer in the world, responsible for more than 500 000 deaths annually. Estimates are that 1 in 8 women will develop breast cancer ... -
Characterization of bacterial species in Steinkopf a communal farming area in South Africa: A closer look at pathogenesis
(University of the Western Cape, 2019)The human population in sub-Saharan Africa has been increasing due to decreases in mortality rates and increases in average human age; in turn increasing poverty and pressure placed on agriculture and agricultural production. ... -
Characterization of Candida species isolated from the oral mucosa of HIV-positive African patients
(UWC, 2013)One of the most common HIV-associated opportunistic infections is candidiasis, caused by Candida albicans or other Candida species. In immune suppressed subjects, this commensal organism can cause an increase in patient ... -
Characterization of candida species isolated from the oral mucosa of HIV-positive African patients
(2013)One of the most common HIV-associated opportunistic infections is candidiasis, caused by Candida albicans or other Candida species. In immune suppressed subjects, this commensal organism can cause an increase in patient ... -
Characterization of flowpaths to improve the prediction of vegetation impacts on hydrological processes in semi-arid mountainous catchments of the Cape Fold Belt
(University of Western Cape, 2021)Mountainous areas are important water sources in many landscapes. An understanding of how mountainous catchments function is important particularly in semi-arid areas, where water shortages are prevalent. In addition to ... -
Characterization of joints in the Keimoes suite with respect to Namaqua deformation events
(University of the Western Cape, 2013)The Keimoes Suite is a group of poorly defined granitoids that characterize the Namaqua Front and Foreland zones. There is a lack of knowledge on its content and distribution. A significant amount of work has been done on ... -
Characterization of platinum-group metal nanophase electrocatalysts employed in the direct methanol fuel cell and solid-polymer electrolyte electrolyser
(University of the Western Cape, 2005)Characterization of nanophase electrocatalysts, which are an essential part in the direct methanol fuel cell (DMFC) and solid-polymer electrolyte (SPE) electrolyser, have been studied in this work. Their nanoparticulate ... -
Characterization of potential source rocks of the Prince Albert, Whitehill and Collingham formations in the Laingsburg sub-basin, South Africa
(University of the Western Cape, 2014)The present research deals with the characterization of the Lower Ecca Group in terms of sedimentology, mineralogy and organic geochemistry. A field study was conducted in order to characterize the sedimentology and thereby ... -
Characterization of the role of a cycloartenol synthase gene (ZMCAS494) in Zea mays responses to drought stress
(University of the Western Cape, 2016)Plant Sterols are an important part of the membrane and their role is to control cell membrane fluidity and permeability. Several studies have indicated that plants that are mutant for genes that play a role in the sterol ... -
Characterization of the role of single domain soybean cystatins in regulating drought responses in soybean
(University of the Western Cape, 2015)This study investigated the effects that drought stress imposed on the growth and development of soybean plants. Soybeans were initially observed at the whole-plant level in order to identify the physical changes that had ... -
Characterization of the role of Zea mays burp domain-containing genes in maize drought responses
(University of the Western Cape, 2016)Global climate change has resulted in altered rainfall patterns, causing annual losses in maize crop yield due to water deficit stress. Therefore, it is important to produce maize cultivars which are more drought-tolerant. ... -
Characterization of two Arabidopsis thaliana genes with roles in plant homeostasis
(University of the Western Cape, 2004)Plants are continuously exposed to varying conditions in their environment, to which they have to adapt by manipulating various cellular processes. Environmental (abiotic) and pathogen (biotic) stress are challenges against ... -
