The antioxidant properties of melatonin during chemical hypoxia and reoxygenation injury in rat ventricular myocytes
(University of the Western Cape, 2000)It is well known that ischaemia chemical hypoxia followed by reperfusion is not always accompanied by recovery of myocardial function and often produces further cell damage (Hearse et al., 1973). This phenomenon commonly ... -
Apoptotic markers in ejaculated human spermatozoa
(University of the Western Cape, 2005)The role of male germ cell death in spermatogenesis is an important one as it removes dysfunctional or genetically damaged germ cells and is necessary to maintain an optimal germ cell to Sertoli cell ratio. The formation ... -
Applicability of big data analytics to support groundwater management in Southern Africa
(University of the Western Cape, 2022)Groundwater is a vital resources for member states in the Southern African Development Community (SADC). However, sustainable managing groundwater resources in SADC is a challenge. Amongst the many issues facing groundwater ... -
Application of anomaly detection techniques to astrophysical transients
(University of Western Cape, 2021)We are fast moving into an era where data will be the primary driving factor for discovering new unknown astronomical objects and also improving our understanding of the current rare astronomical objects. Wide field ... -
Application of enviromental and hydrochemical analysis to characterize flow dynamics in the Sakumo Wetland, Ghana
(University of the Western Cape, 2018)This research focused on understanding the current hydrogeology of the Sakumo wetland by developing a conceptual flow model and simulating the groundwater flow system. The purpose of the model is to assist in understanding ... -
Application Of environmental tracer methods to conceptualize groundwater recharge, West Coast, South Africa
(University of the Western Cape, 2019)Drought and climate change will have adverse consequence for freshwater resources in water stressed South Africa. Diminishing surface water reserves increases the demand to exploit groundwater resources. The drought ... -
An application of factor analysis on a 24-item scale on the attitudes towards AIDS precautions using Pearson, Spearman and Polychoric correlation matrices
(University of the Western Cape, 2006)The 24-item scale has been used extensively to assess the attitudes towards AIDS precautions. This study investigated the usefulness and validity of the instrument in a South African setting, fourteen years after the ... -
Application of fluid electrical conductivity logging for fractured rock aquifer characterisation at the University of the Western Cape's Franschhoek and Rawsonville research sites
(University of the Western Cape, 2011)Characterisation of fractured rock aquifers is important when dealing with groundwater protection and management. Fractures are often good conduits for water and contaminants, leading to high flow velocities and the fast ... -
Application of geochemical characterization, multivariate statistics and geological modelling in assessment and prediction studies on selected coal and gold mine waste in South Africa
(University of the Western Cape, 2023)Over the years, South Africa has generated vast amounts of coal fly ash and gold slime tailings, constituting over 70% of the country's waste materials. These byproducts contain elevated levels of trace metals, posing a ... -
The application of geophysical wireline logs for porosity and permeability characterisation of coal seams for coal bed methane evaluation : Waterberg Basin, South Africa
(University of the Western Cape, 2012)The fracture porosity and permeability of the Beaufort Seam 1 (BS1) and Ecca coal seams of the Waterberg Basin have been comprehensively characterised with the aid of geophysical wire‐line logs. The main aim of the thesis ... -
The application of high capacity ion exchange absorbent material, synthesized from fly ash and acid mine drainage, for the removal of heavy and trace metals from secondary co-disposed process waters
(University of the Western Cape, 2005)The objective of this study was to investigate the feasibility of the application of low cost high capacity inorganic ion exchange material, synthesized form collected fly ash and acid mine drainage solid residues, for the ... -
The application of magnetic resonance and computed tomography imaging in the diagnosis and management of maxillofacial tumours
(University of Western Cape, 2004)The Application of Magnetic Resonance (MRI) and Computed Tomography Imaging (CT) in the Diagnosis and Management of Maxillofacial Tumours. For decades maxillofacial surgeons over the world have been frustrated by the high ... -
An Application of Multiple Regression in Exchange Rate Arrangements
(University of the Western Cape, 2008)This project "An application of multiple regression in exchange rate arrangement" focused on the processes followed by different countries when choosing an exchange rate regime for currency stabilization. It analyses the ... -
Application of multivariate statistics and Geographic Information Systems (GIS) to map groundwater quality in the Beaufort West area, Western Cape, South Africa
(UWC, 2013)Groundwater in arid and semi-arid areas like the Karoo region of South Africa is an important source of domestic, agricultural and industrial source of fresh water. As a scarce resource, it requires extensive quality control ... -
The application of novel multinuclear catalysts derived from dendrimeric ligands in the polymerization and oligomerization of unsaturated hydrocarbons
