Characterisation of N-terminal fragments of Retinoblastoma Binding Protein 6 for structural analysis
(University of the Western Cape, 2016)Retinoblastoma Binding Protein 6 (RBBP6) is a 200 kDa RING finger-containing protein that plays a role in 3'-end poly-adenylation of mRNA transcripts as well as acting as an E3 ubiquitin ligase against a number of proteins ... -
Characterisation of natural radioactivity in Karoo Basin groundwater prior to shale gas exploration
(University of the Western Cape, 2017)The prospect of unconventional shale-gas development in the Karoo Basin (South Africa) has created the need to obtain baseline data on natural radioactivity in Karoo groundwaters. The Karoo Basin groundwater radiological ... -
Characterisation of the endophytic bacterial communities associated with South African sorghum plants: looking for potential plant growth-promoting endophytes
(University of Western Cape, 2012)The term endophyte is used to define all microorganisms that, during a part of their life cycle, colonize the internal tissues of a plant host. Many endophytes have been found to promote plant growth by acting either as ... -
Characterisation of the first 1/2+ excited state in 9B and isospin symmetry breaking studies in A = 9 nuclei
(University of the Western Cape, 2019)The 9Be - 9B isospin doublet carries fundamental significance for both nuclear structure and nuclear astrophysics studies. The first excited 1/2+ state in 9Be is already well established. However, its isobaric analogue ... -
Characterisation, Isolation, Purification and Toxigenicity ofDiplodiatoxin produced by Stenocarpella maydis in Maize
(University of the Western Cape, 2002)Mycotoxins attract worldwide attention because of the significant economic losses associated with their impact on human health, animal productivity, domestic and international trade. Over 300 mycotoxins have been discovered, ... -
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 ... -
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 ... -
