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
(University of the Western Cape, 2007)G1 and G2 dendrimeric salicylaldimine ligands containing both substituted and unsubstituted aryl rings were synthesized via a Schiff base condensation of the appropriate salicylaldehyde and the peripheral amino groups of ... -
Application of petrophysics and seismic in reservoir characterization. A case study on selected wells, in the Orange Basin, South Africa
(University of the Western Cape, 2012)The evaluation of petroleum reservoirs has shifted from single approach to an integrated approach. The integration, analysis and understanding of all available data from the well bore and creating property models is an ... -
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ... -
The application of statistical and machine learning techniques for DDOS detection in network information systems
(University of the Western Cape, 2022)A surge of large-scale Distributed Denial of Service (DDoS) attacks has swept the internet in recent years, possibly presenting a serious threat to industry internet service offerings. These attacks take advantage of ... -
Application of Sutherlandia flutescens in cosmetic skin industry (phytochemical fingerprinting and its activity against skin immune diseases.
(University of the Western Cape, 2019)Hyperpigmentation disorders such as melasma, freckles and black-pigmented spots on the surface of the skin are often a result of increased over production and accumulation of melanin pigments in the skin. In melanin ... -
Application of vertically aligned arrays of metal-oxide nanowires in heterojunction photovoltaics
(University of the Western Cape, 2020)The commercial need to improve the performance of low-cost organic solar cells has led to the idea for this research. The study discusses the synthesis of one dimensional TiO2 and ZnO nanowire arrays synthesised using a ... -
Applications of DNA-barcoding in the identification and understanding of grass invasions in Southern Africa
(University of the Western Cape, 2014)The spread of invasive species is one of the greatest threats to global biodiversity. Alien plant invasions also have serious economic impact in terms of the delivery of ecosystem goods and services. Studies of biological ... -
Applying a lagrangian trajectory model to investigate and describe the distribution of drifting ecklonia maxima within the benguela upwelling system
(University of the Western Cape, 2023)Macroalgal morphological variation is determined to a large extent by a combination of environmental factors, with wave exposure and temperature perhaps the main influences, as they are key environmental properties to which ... -
An approach to acquifer test pumping in fractured crystalline aquifers with a case study in Namaqualand
(University of the Western Cape, 2002)Water resources in South Africa are being stressed. Due to this concern more emphasis should be placed on determining where we can improve our existing methods for the calculation of sustainable yield. Current approaches ... -
An approach to groundwater targeting in the Springbok region, central Namaqualand, Northern Cape Province, South Africa
(University of the Western Cape, 2003)Namaqualand is a semi-arid region where water is not only a necessity and basic need, but also very much a luxury. As a consequence, various studies were undertaken to find water sources, whether surface or groundwater, ... -
