The effect of sunitinib on neuroblastoma and glioblastoma cell growth
(University of the Western Cape, 2020)Cancer is a global health catastrophe, with neuroblastoma, the most common solid childhood tumor, and glioblastoma, a deadly brain tumor, being aggressive and unresponsive to current treatment modalities. These tumors are ... -
Effect of synthetic methods on the characteristics and performance of IrO2 catalysts
(University of the Western Cape, 2022)For many years fossil fuel has been the primary source of energy worldwide though, the environment is negatively affected because of the high carbon dioxide (CO2) emissions associated with the use of fossil fuels. Hydrogen ... -
Effect of tea and herbal infusions on mammalian reproduction and fertility
(University of the Western Cape, 2013)Camellia sinensis (tea) and Aspalathus linearis (rooibos) may improve reproductive function owing to their antioxidant properties. To test this hypothesis, male and female rats were given 2% and 5% green tea (Gt), black ... -
Effect of the additional electron acceptor in hybrid ZnO: P3HT:PCBM spin-coated films for photovoltaic application
(University of the Western Cape, 2015)In a quest for low operational and maintenance cost solar cell devices, organic photovoltaics remain a potential source of energy worthy to be explored. In order to generate cost- effective electricity from solar energy, ... -
Effect of Tulbaghia violacea on the blood pressure and heart rate in male spontaneously hypertensive wistar rats
(University of the Western Cape, 2011)Tulbaghia violacea Harv. (Alliaceae) is a small bulbous herb which belongs to the family, Alliaceae, most commonly associated with onions and garlic. In South Africa (SA), this herb has been traditionally used in the ... -
Effect of zinc oxide nanoridge height on solar cell performance
(University of Western Cape, 2021)Environmentally friendly photovoltaic devices make use of solar radiation as the energy source to generate electricity. Organic solar cells (OSCs) have been making headway in the last decade due to their cost-effectiveness ... -
The effectiveness of using pictograms and text on medication labels at primary healthcare facilities in Cape Town
(University of the Western Cape, 2020)Medication labels are often the only information available to patients after obtaining medication 3 from the pharmacy or other healthcare practitioners. Inappropriately designed medicine labelling 4 contributes to poor ... -
Effects of acid concentration on the extraction of rare earth elements from South African Coal Fly Ash
(University of Western Cape, 2021)Coal is seen as a reliable and secure energy source in many countries around the world despite the development of a number of alternative sources of energy. A rise in global energy demand has led to an increase in coal ... -
The effects of anthropogenic disturbance upon African penguin colonies
(University of Western Cape, 2020)African penguin (Spheniscus demersus) mainland colonies are a popular tourist attraction in the Western Cape of South Africa. The African penguin population is in decline and the species is listed as endangered on the ... -
The effects of artificial and natural sweeteners on various physiological systems
(University of the Western Cape, 2011)This study aimed to investigate the effects of commercially available natural (sugar cane molasses, white sugar and brown sugar) and artificial (Canderel, Equal, Natreen, Sweetex, Splenda and Swheet) sweeteners on various ... -
The Effects of Cadmium and Lead on Phaseolus vulgaris
(University of the Western Cape, 2012)The demand for better quality produce by consumers is on the increase, as higher heavy metal concentrations pose a problem in agriculture. They result in decreased yield and unsuitable food for human consumption. This ... -
The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ... -
The effects of carbon-based nanoparticle surface functionalization on immune responses
(University of the Western Cape, 2022)Nano-based technologies are highly desired for the unique properties achieved through size restrictions. Nanoparticles (NPs) achieve a higher surface-to-volume ratio during synthesis. As a result there is a greater rate ... -
Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape
(University of the Western Cape, 2019)River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ... -
Effects of clay minerals on the petrophysical properties of sandstone reservoirs from the Offshore Pletmos Basin, South Africa
(University of the Western Cape, 2019)With the latest advancements in the Pletmos Basin it is imperative to understand and study how sandstone reservoirs are affected by clay minerals. Clay minerals are an influential component in sandstone reservoirs worldwide ... -
The effects of clipping and burning on the allocation of total nonstructural carbohydrates and selected mineral nutrients in Imperata cylindrica (L.) Raeuschel
(University of the Western Cape, 1999)The rhizomatous grass, Imperata cylindrica, occurs in the Cape Flats Nature Reserve (CFNR), South Africa. It is recognised globally as a weed of crop plants. The response of this weed to defoliation, in the forms of clipping ... -
The effects of differences in feeding regime and of export simulations on the growth of the abalone Haliotis midae Linnaeus
(University of the Western Cape, 2008)Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not always ... -
