Exploring diversity and ecology of nonarchaea in hydrothermal biotopes
(University of the Western Cape, 2005)The Nanoarchaeota were proposed as the fourth archaeal sub-division in 2002, and the only fully characterized nanoarchaeon was found to exist in a symbiotic association with the crenarchaeote, Ignicoccus sp. This nanoarchaeote, ... -
Exploring low-cost solution for 3D crime scene data gathering with immersive technology
(University of the Western Cape, 2023)3D crime scene data gathering is critical for law enforcement and investigators during crime scene investigations. Crime scene investigations have seen the effective usage of Light Detection and Ranging (LiDAR) scanners ... -
Exploring opportunities for job creation through waste value chain: Removal of alien invasive plants, Western Cape, South Africa
(University of the Western Cape, 2022)Alien invasive plants are often end up in landfills after they are removed, where they form part of organic waste. Wood contractors can utilise this organic waste as a source of informal employment, which is also a waste ... -
Exploring poly (2, 5) benzimidazole enhanced with carbon nanotubes for space applications
(University of the Western Cape, 2023)This work explores using polymeric materials for space radiation shielding in low-earth orbit. Shielding against radiation is essential on any space mission. Low atomic number materials, such as hydrogen, have shown to be ... -
Exploring the factors influencing the sustainability of mobile clinics for the delivery of the expanded programme on immunisation to the rural areas of the Northern Cape.
(University of Western Cape, 2021)The Northern Cape province has not been able to achieve the 90% immunization target recommended for South Africa’s expanded programme on immunisation (EPI). The situation has been attributed to the lack of access to EPI ... -
Exploring the influence of organisational, environmental, and technological factors on information security policies and compliance at South African higher education institutions: Implications for biomedical research.
(University of the Western Cape, 2020)Headline reports on data breaches worldwide have resulted in heightened concerns about information security vulnerability. In Africa, South Africa is ranked among the top ‘at-risk’ countries with information security ... -

Exploring the role of the “glycan-shield” of human immunodeficiency virus in susceptibility to, and escape from, broadly neutralising antibodies
(University of the Western Cape, 2018)The HIV-1 envelope (Env) glycoprotein is the primary target of the humoral immune response and a critical vaccine candidate. However, Env is densely glycosylated and thereby substantially protected from neutralisation. ... -
Expression and purification of the novel protein domain DWNN
(University of the Western Cape, 2002)Proteins play an important role in cells, as the morphology, function and activities of the cell depend on the proteins they express. The key to understanding how different proteins function lies in an understanding of the ... -
Expression of human coronavirus NL63 and SARS-CoV nucleocapsid proteins for antibody production
(University of the Western Cape, 2012)Human Coronaviruses (HCoVs) are found within the family Coronaviridae (genus, Coronavirus) and are enveloped, single-stranded, positive-sense RNA viruses. Infections of humans by coronaviruses are not normally associated ... -
Expression of recombinant S-locus F-box-S2 protein and computational modeling of protein interaction at the self-incompatibility locus of Rosaceae
(2012)Self-incompatibility (SI) is a major mechanism that prevents inbreeding in ow-ering plants, which was identi ed in Rosaceae, Solanaceae and Scrophulariace. In these families, SI is gametophytic and retains inter-speci ... -
Expression of stress-tolerance related genes in Saccharomyces cerevisiae producing heterologous cellobiohydrolase.
(University of the Western Cape, 2017)Cellulose is the most abundant naturally occurring renewable biopolymer on earth and a major structural component in plant cell walls, making it an ideal source of renewable energy. Consolidated bioprocessing (CBP) is a ... -
Expression studies of human coronavirus nl63- nucleocapsid, membrane and envelope proteins
(2013)Acute respiratory infections (ARI) continue to be the leading cause of acute illnesses worldwide and remain the most important cause of infant and young children mortality. Many viruses such as rhinoviruses, influenza ... -
Extant benthic Foraminifera from two bays along the SW coast of South Africa, with a comment about their use as indicators of pollution
(University of the Western Cape, 2010)The results of the multivariate analyses suggest that most of the variation in the composition of the samples was of an intra-sample nature, illustrating large scale patchiness in foraminiferal distribution. There were, ... -
Extraction, fractionation, nanoparticles formulation, and antimicrobial activity of lipids from black soldier fly larvae
(University of Western Cape, 2021)Hermetia illucens (Diptera: Stratiomyidae) known as the black soldier fly (BSF) is an efficient ecological organic waste decomposer. Its larvae grow through six larval instars on a variety of decomposing organic substrates ... -
The extraction, purification and evaluation of compounds from the leaves of Leonotis Leonorus for anticonvulsant activity
(University of the Western Cape, 2002)The aim of this study is to isolate and evaluate the anticonvulsant components from the leaves of Leonotis leonorus (L) R.aR. and to see if there is any change in activity with the origin of the plant material and I or the ... -
Fabrication and characterization of a solar cell using an aluminium p-doped layer in the hot-wire chemical vapour deposition process
(2010)When the amorphous silicon (a-Si) dangling bonds are bonded to hydrogen the concentration of the dangling bond is decreased. The resulting film is called hydrogenated amorphous silicon (a-Si:H). The reduction in the dangling ... -
