Domestic greywater systems: a potential reservoir of antibiotic resistance genes transfer
(University of the Western Cape, 2024)During the Western Cape drought from 2015 to 2018, the use of greywater to alleviate pressure on the limited potable water available in the province was encouraged. Greywater, however, has the potential to harbour residual ... -
A dual analysis of the South African Griqua population using ancestry informative mitochondrial DNA and discriminatory short tandem repeats on the Y chromosome
(University of the Western Cape, 2015)The primary objective of this Masters project was to investigate the maternal ancient substructure of the Griqua population in South Africa. Genetic ancestry was determined by investigating ancestry informative single ... -
Durability studies of membrane electrode assemblies for high temperature polymer electrolyte membrane fuel cells
(University of the Western Cape, 2011)Polymer electrolyte membrane fuel cells (PEMFCs) among other fuel cells are considered the best candidate for commercialization of portable and transportation applications because of their high energy conversion and low ... -
Dynamic variation of hydrogen dilution during hot-wire chemical vapour deposition of silicon thin films
(University of the Western Cape, 2013)This study reports on the effects of hydrogen dilution and deposition time on six silicon thin films deposited at six specific deposition regimes. The thin film properties are investigated via X-Ray diffraction analysis, ... -
Dynamics and biological implications of the Port St Johns cyclonic lee eddy
(University of the Western Cape, 2016)This project describes the current dynamics of the cyclonic lee eddy off Rame Head, Port St Johns and Waterfall Bluff, and how its physical forcing may influence the biological communities. Three research surveys were ... -
The dynamics of modern method contraception among sexually active unmarried adolescents in Nigeria
(University of the Western Cape, 2022)It is just stating the obvious to aver that young people in all regions are reaching puberty earlier and are habitually engaging in sexual activity at a younger age, and thereafter, marrying later. As a result, they are ... -
The dynamics of stakeholder participation in water resources management in Zimbabwe: a case study of the agricultural sector
(University of the Western Cape, 2004)The major aim of this study was to analyse the dynamics of stakeholder participation in the agricultural sector during the first five years of the water reform process in Zimbabwe. Specific reference is made to water ... -
E2/M1 mixing in the Jπ= 5/2+ to 3/2+ transition in 21Na and its relation to the 20Ne(p,y ) stellar reaction rate
(University of the Western Cape, 2022)In the above, M is the total mass of the molecular cloud, R is its radius, k is Boltzmann's constant, G is the gravitational constant, T is the cloud temperature, m is the mean molecular weight, and is the cloud molecular ... -
Ecklonia maxima kelp forests along a thermal gradient: community composition and recovery from disturbance
(University of the Western Cape, 2017)Climate change will influence species distributions, survival and ecosystem functioning, mostly through changes in sea surface temperatures and storm disturbance. Species are expected to shift poleward in response to ocean ... -
The ecohydrology of the Franschoek Trust Wetland: water, soils and vegetation
(University of the Western Cape, 2010)The research was driven by a need to increase the knowledge base concerning wetland ecological responses, as well as to identify and evaluate the factors driving the functioning of the Franschhoek Trust Wetland. An ... -
The ecohydrology of the Fransehoek Trust Wetland: water, soils and vegetation.
(University of the Western Cape, 2010)The research was driven by a need to increase the knowledge base concerning wetland ecological responses, as well as to identify and evaluate the factors driving the functioning of the Franschhoek Trust Wetland. An ... -
Ecology and conservation of high altitude amphibians
(UWC, 2002)This study looked at the breeding ecology of the anurans, found in the Landdroskop mountain range in Grabouw, and some recommendations as to their conservation are made. There is very little known about the frogs in South ... -
Ecology and diet of the caracal (Caracal caracal) on lethal and non-lethal control farms in the Karoo
(University of the Western Cape, 2020)Human-wildlife conflict is an ongoing issue worldwide. Within South Africa, human-carnivore conflict (HCC) as a result of carnivore depredation on small-livestock causes large-scale losses, and promotes the use of predator ... -

Ecology and morphology of the Kalahari tent tortoise, Psammobates oculifer, in a semi-arid environment
(University of the Western Cape, 2012)Southern Africa harbours one-third of the world's Testudinid species, many of which inhabit arid or semi-arid areas, but ecological information on these species is scant. I studied the habitat, morphology and ecology of ... -
The ecology of tadpoles in a temporary pond in the Western Cape with comparisons to other habitats
(University of the Western Cape, 2006)This work centered on the tadpoles in a temporaray pond in the middle of Kenilworth racecourse, Cape Town, South Africa. Trapping was carried out over two wet seasons and five species were found. The racecourse was selected ... -
