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 ... -

Fabrication and kinetic modeling of cytochrome P4502D6 amperometric biosensors for serotonin reuptake inhibitors
(University of the Western Cape, 2005)An amperometric biosensor was prepared by in situ deposition of cytochrome P4502D6 (CYP2D6, P4502D6) enzyme on a polyaniline (PANI)-doped glassy carbon electrode. The PANI film was electrochemically deposited on the electrode ... -
Fabrication of luminescent nanocomposites for diagnosis of breast cancer
(University of the Western Cape, 2016)In this study we were able to synthesize separately iron oxide magnetic nanoparticles, InP/ZnSe and CdTe/ZnS quantum dots. The iron oxide nanoparticles were coupled with InP/ZnSe QDs to form the luminescent magnetic ... -
Fabrication of metal-organic frameworks with application-specific properties for hydrogen storage application
(University of Western Cape, 2019)The application of porous materials into industrial hydrogen (H2) storage systems is based on their use in combination with high-pressure cylinders. The processing of metal-organic frameworks (MOF) powders into shaped ... -
Fabrication of nanomaterials from biomass for adsorption and antimicrobial applications
(University of the Western Cape, 2020)The Black soldier fly (BSF) is an environmentally friendly and sustainable insect utilised in the decomposition of organic waste. This is due to its voracious consumption capability, disruptive functions and economic ... -
Fabrication of type-I indium-based near-infrared emitting quantum dots for biological imaging applications
(University of the Western Cape, 2013)Semiconductor nanocrystals or quantum dots (QDs) are fluorescent nanometer-sized particles which have physical dimensions that are smaller than the excitonic Bohr radius, large surface area-to-volume ratios, broad ... -
Facies, depositional environments and reservoir properties of the albian age gas bearing sandstone of the ibhubesi oil field, orange basin, South Africa
(University of the Western Cape, 2009)The Orange Basin was formed during the late Jurassic to early Cretaceous periods due to Gondwana breakup and rifting and later drifting apart of the African and South American plates. The basin consists of siliciclastic ... -
Factors affecting the enrolment rate of students in higher education institutions in the Gauteng province, South Africa : based on General Household Survey 2012
(University of the Western Cape, 2015)Background: In South Africa, many students are not able to register at higher education institutions after receiving their high school diploma. The majority of those who do register do not even complete their tertiary ... -
Factors affecting the pharmacokinetics of vancomycin in children admitted to the intensive care unit (icu) of the Red Cross War Memorial Children's Hospital (RCWMCH).
(University of the Western Cape, 2023)Vancomycin is a glycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminal end of cell wall precursor units preventing the elongation and cross-linkage of the ... -
Factors associated with land acquisition for food production among small-scale farmers in South Africa
(University of Western Cape, 2021)The purpose of this study is to investigate determinants of land tenure, agricultural activities involvement, and the use of agricultural products and stock keeping among small-scale farmers across all nine provinces of ... -
Factors associated with low-use of skilled birth attendants in Zimbabwe
(University of the Western Cape, 2019)Skilled birth attendance at childbirth is vital for decreasing maternal and child mortality in Zimbabwe. Infant mortality and maternal mortality in Zimbabwe are quite high due to low- use of skilled birth attendance. Based ... -
Factors associated with participation in physical activity among adults with diabete mellitus in Kigali, Rwanda
