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 ... -
Characterizing native palatable legume and non-legume species in the rangelands of the Overberg area
(University of the Western Cape, 2020)The Overberg renosterveld rangelands of the Cape Floristic Region (CFR) has become well associated with commercial and communal agricultural practices, namely crop and livestock production. This Mediterranean region is ... -
Characterizing water quality of rivers and underlying aquifers in the Nuwejaars Catchment, South Africa
(University of Western Cape, 2020)Non-perennial rivers are the main source of surface water in drylands. These rivers are unpredictable and highly variable in terms of flow regime and water quality. Despite their abundance, and importance in the landscape, ... -
Charge Transfer and Capacitive Properties of Polyaniline/ Polyamide Thin Films
(University of the Western Cape, 2018)Blending polymers together offers researchers the ability to create novel materials that have a combination of desired properties of the individual polymers for a variety of functions as well as improving specific properties. ... -
Charge transfer efficiency and optical properties of P3HT/PCBM spin coated thin films
(UWC, 2009)The efficiency of organic photovoltaics is influenced by the structure of the polymer, the morphology of the film, the interfaces between the layers, the choice of electron acceptor material and the ratio between the ... -
Checking the Kulcha: Local discourse of culture in the Kavango region of Namibia
(University of Westen Cape, 2006)This thesis makes an ethnographic contribution to the anthropological debates about the contested nature of ‘culture’ as a central term in the discipline. It examines discourses as tools that create, recreate, modify and ... -
The chemical and biological characterization of South African helichrysum species
(University of the Western Cape, 2015)South Africa has immensely rich natural flora diversity with more than 20 000 species of higherplants. Asteraceae is one of the biggest families of flowering plants with about 246 genera and 2,300 species in southern Africa. ... -
Chemical and biological evaluation of palythoa tuberculosa collected from the red sea
(University of the Western Cape, 2015)A chemical study on the total extract of the zoanthid Palythoa tuberculosa, collected from the Red Sea, resulted in the isolation of seven polyhydroxylated sterols viz: palysterols A-G, six of which are new. Their chemical ... -
