Assessment of water service delivery in the municipalities of City of Tshwane, City of Cape Town and Ethekwini
(University of the Western Cape, 2016)Access to water and water scarcity are the most critical impediments to sustainable development in municipal water provision. Good water and sanitation services are essential for health, economic development, and environmental ... -
An assessment of water use by riparian and non-riparian invasive alien plants and the effects on water resources at the catchment scale
(University of the Western Cape, 2023)The diversity and increasing extent of invasive alien plants (IAPs) are currently a global ecological and economic problem, especially in semi-arid regions. The introduction of IAPs worsens the strain in South Africa’s ... -
Assisted flocculation of Chlorella Sorokiniana by co-culture with filamentous fungi
(University of the Western Cape, 2015)Biofuel production from microalgae is currently not economically competitive with fossil fuels due to high operational costs. A sustainable system needs to be developed which considers cultivation, harvesting and conversion ... -
Association between antioxidant activities and drought responses of two contrasting sugar beet genotypes
(University of the Western Cape, 2017)Sugar beet (Beta vulgaris L), which belongs to the Amaranthaceae family is a biennial crop widely used as a source of domestic sugar in the European countries, United States, China and Japan. However, in South Africa, sugar ... -
The association between environmental exposures during childhood and the subsequent development of crohn's disease in the Western Cape
(University of the Western Cape, 2015)Background: A subtype of inflammatory bowel disease, Crohn’s disease is thought to represent a complex interaction between environmental factors, a defective immune system, the gastrointestinal microbiome and genetic ... -
The association of BMI and blood pressure measurements with depressive and quality of life scores in university students
(University of the Western Cape, 2022)Depression is a very common and serious mental illness. Studies have shown that depression has a significant impact on both social and economic aspects of sufferers worldwide as well as in South Africa. Research has shown ... -

AtNOGC1 protein bioelectrode for the determination of stress signalling molecules - Nitric Oxide (NO), Carbon Monoxide (CO) and Calcium ion (Ca2+)
(University of the Western Cape, 2018)It has been estimated that the world population will reach about 10 billion by the year 2050 and in order to accommodate the increased demand of food, the world agricultural production needs to rise by 70 % in the year ... -
Autecology of the rhombic egg-eater, Dasypeltis scabra
(University of the Western Cape, 2022)Efforts to prevent global losses of biodiversity are hindered by incomplete knowledge of the functional importance of species. In part, this is due to a paucity of information on the basic biology of most species resulting ... -
Automatic real-time facial expression recognition for signed language translation
(University of the Western Cape, 2006)We investigated two computer vision techniques designed to increase both the recognition accuracy and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of ... -
Automatic signature verification system
(2013)In this thesis, we explore dynamic signature verification systems. Unlike other signature models, we use genuine signatures in this project as they are more appropriate in real world applications. Signature verification ... -
Automorphism groups of some designs of steiner triple systems and the atomorphism groups of their block intersection graphs
(University of the Western Cape, 2014)A Steiner triple system of order v is a collection of subsets of size three from a set of v-elements such that every pair of the elements of the set is contained in exactly one 3-subset. In this study, we discuss some ... -
