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, ... -

Aptamer selection against GFRa1 for its application in the prognosis of breast cancer
(University of the Western Cape, 2019)Breast cancer is the second most common cancer amongst South African women. Despite ongoing efforts to combat breast cancer, current prognostic and/or therapeutic monitoring methods are limited since very little improvement, ... -
Arenas of contestation: policy processes and land tenure reform in post-apartheid South Africa
(University of the Western Cape, 2008)Summary: This thesis considers different groupings that have come together in their participation in the policy processes relating to tenure reform in post-apartheid South Africa. It is methodologically and theoretically ... -
Articulated structure from motion
(University of the Western Cape, 2004)The structure from motion (SfM) problem is that of determining 3-dimensional (3D) information of a scene from sequences of 2-dimensional (2D) images [59]. This information consists of object shape and motion and relative ... -
Aspects of moulting of the South African West Coast rock lobster, Jasus lalandii
(University of the Western Cape, 1998)Background: The wet coast of southern Africa is subject to coastal upwelling and is characterized by often dense kelp beds that can extend as far as 3 km offshore. Kelp forests create a unique ecosystem. Not only are they ... -
Aspects of the gastrointestinal uptake and metabolism of luteolin derivatives from Artemisia afra aqueous extract (preclinical)
(University of the Western Cape, 2011)The aim of this study was to investigate the effect the plant matrix and the structure of the flavonoid (i.e. whether aglycone or glycoside) may have on the gastrointestinal uptake and metabolism of luteolin derivatives ... -
Aspects of the interrelation between hypertension and insulin resistance
(University of the Western Cape, 2009)Conclusion of this study: These data suggest that 6 weeks of high-fat feeding induces hypertension but does not produce obesity, dyslipidemia and insulin resistance. However, this model may be useful in studying vascular ... -
Aspects of the interrelation between hypertension and insulin resistance: a preliminary study
(2009)Background: It is well known that some genetic factors and dietary factors, such as excessive salt intake and excessive caloric intake (resulting in obesity) are risk factors for hypertension. Fifty percent of all ... -
Aspects of the reproduction of male and female African penguins (Spheniscus demersus) with special reference to sperm biology and cryopreservation
(University of the Western Cape, 2018)In the marine environment, penguins have been described as curators and serve a critical role in ecological balance. The African penguin (Spheniscus demersus) has undergone a rapid population decline, mainly due to ... -
Aspects of the reproductive physiology of male vervet monkeys maintained in a laboratory environment
(University of the Western Cape, 1995)In biomedical research limited use has been made internationally of African non-human primates. As a result, their reproductive physiology has been less well defined, when compared to the more commonly used macaque species. ... -
Assessing different coal combustion residue backfill scenarios in opencast coal mines, Mpumalanga, South Africa
(University of Western Cape, 2020)Coal-fired power stations produce large volumes of coal combustion residues (CCRs), which are disposed of in hold ponds or landfill sites. These ash storage facilities are limited in space and are approaching the end of ... -
Assessing effectiveness of groundwater remediation technologies to a coastal aquifer within an urban environment in South Africa
(University of the Western Cape, 2022)The study aimed to assess the effectiveness of Reverse Osmosis technology as an example of ex-situ groundwater remediation technologies. The Cape Flats Aquifer System, an urban coastal system, was used as a case study. ... -
