Diversity of Frankia associated with Morella species of the Cape floristic region of Southern Africa
(University of the Western Cape, 2016)Frankia is one of two partners in the globally distributed N2-fixing actinorhizal symbiosis between this filamentous soil-dwelling actinomycete and almost 300 species of host plants from eight diverse angiosperm families. ... -
The diversity of key anabolic genes in antarctic hypolithons
(2009)Antarctica is known for its pristine environments. A variety of unsuitable environmental conditions were once thought to render the continent unsuitable for sustaining life. However, metagenomic data have revealed a wealth ... -
DNA metabarcoding for the identification of species within vegetarian food samples
(University of the Western Cape, 2021)Aims DNA metabarcoding has recently emerged as a valuable supplementary tool to ensure food authenticity within the global food market. However, it is widely known that highly processed food samples are one of DNA ... -
Do money managers outperform their respective benchmark? Evidence from South African Unit Trust industry
(University of the Western Cape, 2015)Motivated by the growing attraction of the mutual fund industries across the world, this research seeks to explore the economic benefits contributed by the South African equity unit trust managers over the period from 1 ... -
Do physiotherapy students employ evidence-based practice in the management of musculoskeletal disorders and sports injuries
(2013)Background: Musculoskeletal disorders (MSD’s) and sports injuries are commonly sustained throughout the world daily. They are dominant in many countries, with considerable cost involvement and impact on quality of life. ... -
Documenting the association between a non-geniculate coralline red alga and its molluscan host
(University of the Western Cape, 2010)To further investigate the strength of the association and the relative advantages of the association to both organisms, several manipulation experiments were set up. A cage experiment set up in the shallow subtidal zone ... -
Does maternal nicotine exposure during gestation and lactation change the oxidant-antioxidant status of the lungs of the offsprings and is tomato juice protecting the lungs of the offsprings?
(University of the Western Cape, 2009)Nicotine exposure to the fetus through tobacco smoking or nicotine replacement therapy during the whole period of gestation and lactation causes diverse effects on fetal and neonatal lung development, integrity and maturation ... -
Does Olea africana protect the heart against ischemiareperfusion injury?
(2009)Cardiovascular disease is a major health problem and remains the number one cause of death worldwide. For centuries, medicinal plants have been used in different cultures as medicines for the treatment and control of various ... -
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, ... -
