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 ... -
The association of mercury from dental amalgam with urinary selenium
(University of the Western Cape, 2017)Background: Dental amalgam has been the traditional material for filling cavities in teeth. Mercury (Hg) is a component of dental amalgam, from where it is continuously released and deposited in different tissues, mostly ... -
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 ... -
Autonomous facial expression recognition using the facial action coding system
(University of the Western Cape, 2016)The South African Sign Language research group at the University of the Western Cape is in the process of creating a fully-edged machine translation system to automatically translate between South African Sign Language and ... -
The availability of persons nominated for adverse drug reporting and associated challenges in Gauteng regional and district public hospitals
(University of the Western Cape, 2019)Background and Objectives: The reporting of adverse drug reactions (ADRs) is a major public health necessity. It is estimated that only six to 10 percent of all ADRs are reported worldwide. This number is far less than the ... -
The availability, applicability and utility of information systems engineering standards in South African higher education
(University of the Western Cape, 2016)Higher education institutions in South Africa have invested heavily in information technology and information systems, with variable outcomes. Organisations in other sectors, such as engineering, the defence industry, ... -
Avatar animation from SignWriting notation

Awareness regarding non-steroidal anti-inflammatory drug-related side effects in Johannesburg, South Africa
(University of Western Cape, 2021)Non-steroidal anti-inflammatory drugs (NSAIDs) are amongst the most commonly used medications globally, as they are highly effective and easily accessible. The NSAIDs are indicated for mild to moderate pain management. The ... -
Bacillus licheniformis isolated from Mozambican soil capable of producing 2, 3-butanediol
(The University of the Western Cpae, 2018)Due to the current fossil fuel sources rapidly depleting as a result of the increased global need, alternative, sustainable and renewable sources are required. Biofuels, which are environmentally friendly, meet all the ... -
Bacteriophage diversity in haloalkaline environments
(University of the Western Cape, 2013)There are limited reports on virus population in haloalkaline environments; therefore the aim of this study was to investigate the genetic diversity and biology of bacteriophage communities in these environments. Bacteria ... -
Baobab LIMS: An open source biobank laboratory information management system for resource-limited settings
(University of the Western Cape, 2019)A laboratory information management system (LIMS) is central to the informatics infrastructure that underlies biobanking activities. To date, a wide range of commercial and open source LIMS are available. The decision ... -
Barley anther culture: determining the optimal pre-treatment for green plant regeneration
(2013)Doubled Haploid (DH) Technology is an important tool for plant breeding and biotechnological applications as it accelerates the breeding cycle of plants by shortening the time required to attain homozygosity. Anther culture ... -
A baseline evaluation of the cytotoxicity of gold nanoparticles in different types of mammalian cells for future radiosensitization studies
