The role of salt tectonics in the hydrocarbon potential of the post-salt deposits (Albian to Recent), offshore Gabon
(University of Western Cape, 2014)Following successful discovery and production of hydrocarbons, Gabon is one of the key hydrocarbon target countries in Africa. Located in the Lower Congo Basin, the study area is based in Etame Marin Permit (EMP), which ... -
The role of surface modified TiO2 nanoparticles for application in 68Ge/68Ga generator systems and the use of molecular imprinted polymers for 68Ge breakthrough control
(University of Western Cape, 2021)Titanium dioxide (TiO2) has potential as an adsorbent within the 68Ge/68Ga generator context. To function effectively, three basic requirements are required: optimum 68Ga elution efficiency, stability and removal of the ... -
The role of visualization in the teaching and learning of multivariate calculus and systems of ordinary differential equations
(University of the Western Cape, 2015)The purpose of this study was to investigate the role of visualization in the conceptualisation and solution of problems in multivariate calculus and dynamical systems. The theoretical basis, and the visual and analytical ... -
The roles of intertidal marine gastropod shells as secondary substrate for macroalgae
(University of the Western Cape, 2014)Primary space within the marine benthos is by far the most limited resource for which all sessile organisms must compete. It only ever becomes available when the organisms occupying it dies or are forced to leave the area. ... -
Salinity of irrigation water in the Philippi farming area of the cape flats, Cape Town, South Africa
(University of the Western Cape, 2011)This research investigated the nature, source and the spatial variation of the salinity of the water used for irrigation in the urban farming area of Philippi, which lies in the Cape Flats region of the Cape Town Metropolitan ... -
Salt tolerance and modification of wheat salt resistance by plant hormones
(University of the Western Cape, 2004)The history of salt tolerance and the factors effecting salt resistance of plants were literature surveyed, and it was concluded that ion concentration, salt accumulation, compatible solutes and the genetic traits play a ... -
Sample preparation methods and molecular based detection for the rapid isolation and identification of Listeria monocytogenes in food samples
(University of the Western Cape, 2006)Listeria monocytogenes is a Gram-positive bacterium responsible for listeriosis, a food-borne disease, which may result in severe illness and possible death. The importance of L. monocytogenes as a food-borne pathogen has ... -
Sample selection effects in laduma stacking experiments
(University of the Western Cape, 2023)This study explores the impact of selection effects introduced by input optical cata-logues on high-redshift stacking experiments. Using the Hi stacking technique, the Hi content of LADUMA synthetic data cubes is analyzed ... -
Saturation sequencing, characterisation and mapping of the NBS-LRR resistance gene family in apple, Malus x domestica (Borkh)
(University of the Western Cape, 2008)To date five classes of resistance proteins have been identified in plants and these include the intracellular protein kinases, receptor-like protein kinases with extracellular leucinerich repeat (LRR) domain, LRR proteins ... -
Scalable synthesis of innovative silicon/carbon nanocomposite for next generation lithium-ion battery anodes
(University of the Western Cape, 2022)Silicon is the most promising lithium-ion battery (LIB) anode due to its ultra-high capacity (4200 mAh/g), which is 10 times greater than commercially available graphite anodes (372 mAh/g). Utilizing this large capacity ... -
Scalable Wireless Mesh Networks
(University of the Western Cape, 2016)Wireless Mesh Networks (WMNs) are wireless multi-hop networks built on wireless nodes that operate in an Independent Basic Set Identifier (IBSS) mode of the IEEE 208.11 wireless standard. IBSS is well known as an ad hoc ... -
Science text: Facilitating access to physiology through cognition-based reading intervention
(University of the Western Cape, 1995)Reading and understanding science text is the principal means by which students at tertiary level access scientific information and attain scientific literacy. However, understanding and learning from science texts require ... -
Screening bacterial symbionts of marine invertebrates for ribosomally synthesized natural products
(University of the Western Cape, 2016)Pharmaceutical research and development strategies rely on the constant discovery of novel natural products as potential drugs. Recent studies have shown that the microorganisms associated with sponges are the true producers ... -
Screening extracts of indigenous South African plants for the presence of anti-cancer compounds
(University of the Western Cape, 2006)Early man dabbled with the use of plant extracts to cure ailments. This practice has been passed down from generation to generation and today more than 50% of the world'sdrugs are natural products or derivatives thereof. ... -
Screening for fluorescent and chromoproteins from South African sea anemones
(University of the Western Cape, 2012)Sea anemones (Order Actinaria) are a diverse order from the Class Anthozoa. They are found in all marine habitats at all depths and their symbiotic relationships play an important role in energy transfers especially in the ... -
Screening for subtate tolerant Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2009)In this study G. pallidus RAPc8 NHase mutants were screened for reduced substrate inhibition compared to the wild type enzyme. Wild type and mutant enzymes were expressed and purified using hydrophobic interaction ... -
Screening of marine bacteria as a source of bioactive secondary metabolites
(University of Western Cape, 2021)Marine invertebrate associated (MIA) bacteria are an important source of bioactive secondary metabolites with the potential to address the current anti-microbial resistance crisis experienced globally. Secondary metabolites ... -
Screening of natural products and alkylating agents for antineoplastic activity
(2007)Apoptosis is a process in which a cell programmes its own death. It is a highly organized physiological mechanism in which injured or damaged cells are destroyed. Apart from physiological stimuli however, exogenous factors ... -
