Modelling the growth of large-scale structure with interacting fluids
(University of the Western Cape, 2015)Prevailing astronomical and astrophysical observations suggest that we live in a spatially flat cold dark matter (CDM) universe - currently going through a period of accelerated expansion possibly driven by “dark energy” ... -
Models and applications of wireless networks in rural environments
(University of the Western Cape, 2005)With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural ... -
The moderating effect of microfinance on the financial constraints to SMME growth in South Africa
(University of the Western Cape, 2016)Small, Medium and Micro Enterprises (SMMEs) play a significant role in an economy. Thus, governments all over the world concentrate on the development of the small business sector to endorse economic growth. SMMEs are a ... -
Modes and resemiotisation of HIV and aids messages in the eastern region of Malawi
(2013)This study explores how HIV and AIDS discourse is differently constituted and evaluated across different modes by different communities of speakers in Malawi. Particularly, the study explores how different languages and ... -
Modification of nanostructured carbon based supports for direct methanol fuel cells
(University of the Western Cape, 2022)Palladium (Pd) and Palladium-Ruthenium (Pd-Ru) nanoparticles supported by various carbon nanomaterials which include graphene oxide (GO), reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWCNTs) with their ... -
A modified Adams fusion method for the synthesis of binary metal oxide catalysts for the oxygen evolution reaction
(University of Western Cape, 2020)The majority of the global energy is sourced from conventional fossil fuels. The high demand for energy is accelerating along with the depletion of these fossil fuels. Hence, the shift to renewable energy sources and ... -
The modulating effect of conjugated linoleic acid (CLA) on cancer cell survival in vitro
(University of the Western Cape, 2014)Conjugated linoleic acids (CLA) are geometrical and positional isomers of n-6 octadecadenoic acid (linoleic acid, LA, 18:2n-6), which form part of a family of essential polyunsaturated fatty acids (PUFA). There are 28 ... -
The modulating effect of fatty acids on the lipid profile in colon epithelial mucosa in Vivo
(University of the Western Cape, 2009)Several abnormal conditions, including some cancers, have been associated with changes in the membrane lipid and FA composition. Dietary fat serves as a major source of lipids and FA, particularly the polyunsaturated fatty ... -
Modulation of brassica rapa L. antioxidant activities by exogenous methylglyoxal under zirconium stress
(University of the Western Cape, 2016)With a decrease in water availability and arable land, and the ever-increasing reports of toxic chemical pollutants, it is crucial to elucidate plants’ mechanisms of adaptability to these abiotic stressors. South Africa ... -
Modulation of colon carcinogenesis by dietary ω-6/ω-3 fatty acid ratios : a chemopreventive strategy?
(University of the Western Cape, 2015)The aim of this study was to determine whether dietary fats constituting specific ω-6/ω-3 fatty acids (FA) ratio has chemopreventive modulating effects on the development of colon cancer. Western diets intake of saturated ... -
Modulation of soybean and maize antioxidant activities by Caffeic acid and nitric oxide under salt stress
(University of the Western Cape, 2012)This study explores the roles of exogenously applied nitric oxide, exogenously applied caffeic acid and salt stress on the antioxidant system in cereal (exemplified by maize) and legume (using soybean as an example) plants ... -
Modulation of soybean and maize antioxidant activities by Caffeic acid and nitric oxide under salt stress
(University of the Western Cape, 2012)This study explores the roles of exogenously applied nitric oxide, exogenously applied caffeic acid and salt stress on the ontioxidant system in cereal (exemplified by maize) and legume (using soybean as an example) plants ... -

Molecular analysis of red colouration in 'Bon Rouge' pear (Pyrus communis L.)
(University of the Western Cape, 2018)The 'Bon Rouge' pear cultivar was developed from a bud mutation on a 'Bon Chretien' pear tree. The latter is characterised by green fruit skin and leaves, while 'Bon Rouge' is characterised by red leaves and red fruit skin ... -
The molecular characterisation of a baculovirus isolated from trichoplusia ni
(University of the Western Cape, 2001)In South Africa there are more than 106 insects pests which attack a wide variety of crops. The top ten or twenty of these can seriously limit successful production on the farm. Costs involved in controlling these pests ... -
Molecular Characterisation of the Brassinosteroid, Phytosulfokine and cGMP-dependent Responses in Arabidopsis thaliana
(University of the Western Cape, 2010)In this thesis, we have firstly cloned and expressed the domains that harbours the putative catalytic GC domain in these receptor molecules and demonstrate that these molecules can convert GTP to cGMP in vitro. Secondly, ... -
Molecular characterization of Campylobacter isolates from free range and commercial chicken in South Africa
(University of the Western Cape, 2012)Campylobacter species are the most common bacteria associated with acute diarrhoea and is responsible for 400 to 500 million reported cases globally. It is not uncommon for 35% to 85% of chicken flocks to be infected with ... -
The molecular characterization of trichoplusia ni single nucleocapsid nucleopolyhedrovirus: a study on early regulatory features
(University of the Western Cape, 2003)With the development of biological insecticides, many research efforts have been made in baculoviruses to investigate fundamental molecular aspects of these viruses, such as the function and regulation of genes, genome ... -
Molecular detection and characterisation of RNA viruses of honeybees
(University of the Western Cape, 2009)Propagation methods for honeybee viruses have not changed since these viruses were discovered. There are no suitable cell lines or cell culture techniques available for honeybee viruses. Honeybee viruses have to be manually ... -
Molecular detection and characterisation of RNA viruses of honeybees
(University of the Western Cape, 2009)Honeybees have evolved through the centuries to inhabit most parts of the world except for the extreme Polar Regions. These insects have also been susceptible to pathogens and disease which has always been part of the ...
