Microbial diversity of the Namib Desert salt pans
(University of the Western Cape, 2015)Salt pans are a characteristic feature of many dry deserts. The microbial communities inhabiting salt pans are thought to be particularly complex and are generally dominated by halophilic microorganisms. Although saline ... -
Microbial ecology of hot and cold desert edaphic communities
(University of the Western Cape, 2012)This thesis presents significant advances into the microbial ecology of hypolithic communities in two hyperarid deserts. Deserts account for one fifth of the Earths total surface area. These zones differ substantially in ... -
Microbial quality and safety of ostrich meat
(University of the Western Cape, 2010)The aim of this study was to determine the quality of slaughtered ostrich meat and to evaluate the ostrich slaughter process, to determine whether ostrich meat are contaminated by the in-house slaughtering practices and ... -
A microbiological and molecular study of campylobacter and related species isolated from ostriches (Struthio camelus)
(University of the Western Cape, 2014)Campylobacter and related Epsilonproteobacteria (Arcobacter and Helicobacter) are currently viewed as emerging pathogens and are able to cause gastroenteritis, bacteraemia, the Guillain-Barré syndrome, reactive arthritis ... -
Microbiological parameters that influence the treatment outcomes of monodrug and multidrug-resistant tuberculosis
(University of the Western Cape, 2017)Previous studies have reported microbiological parameters such as HIV infection, resistance to anti-TB drugs such as fluoroquinolones, resistance to previous treatment with anti-TB drugsand extrapulmonary TB, causing poor ... -
Microbiology of fly ash-acid mine drainage co-disposal processes
(University of the Western Cape, 2005)The waste products acid mine drainage formed during coal mining and fly ash from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a remediation system ... -
Microbiology of fly ash-acid mine drainage co-disposal processes
(University of the Western Cape, 2005)The waste products acid mine drainage (AMD), formed during coal mining and fly ash (FA) from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a ... -
Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants
(University of the Western Cape, 2017)The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, ... -
Microfluidic paper based electrochemical sensing devices
(University of the Western Cape, 2019)Microfluidic paper based electrochemical sensing devices (μPEDs) provides a new way for point of care testing (POCT). μPEDs offer an inexpensive, portable, easy to use technology too monitor the environment and diagnose ... -
MicroRNAs as predictive biomarkers for diagnosis and prognosis of colorectal cancer using in silico approaches
(University of the Western Cape, 2019)Colorectal cancer (CRC) is referred to as cancers that arise in the colon or rectum. Rectal cancer is most often defined as cancers originating within 15 cm from the anal verge. The crude incidence of CRC in sub-Sahara ... -
Microscopic analysis of In vitro and In vivo effects of functionalized gold nanoparticles on the liver, kidney, spleen, heart and pancreas of male wistar rats
(University of the Western Cape, 2022)Nanotechnology represents a promising knowledge based platform that can solve human needs and ailments, especially in cases like cancers, diabetes, antibiotic drug resistances etc. Many metallic nanoparticles are being ... -
Microwave synthesis of the Schiff base metal-ligand complexes with Cu and Ni centres
(University of Western Cape, 2021)Nitric oxide (NO) plays a vital role as a biological messenger in biological systems. However, NO detection and quantification have always posed significant complications. There is, therefore, a need to develop new materials ... -
Microwave synthesized ruthenium antimony oxide-graphene nanocomposite materials for asymmetric supercapacitors
(University of the Western Cape, 2022)With the rapid rise in energy demand and ever-escalating environmental hazards, the need for transition from fossil fuel to renewable energy sources is of paramount importance, requiring better and efficient energy storage ... -
Migratory trajectories among street vendors in urban South Africa
(University of the Western Cape, 2011)This study investigates ways in which migratory trajectories relate to the gradual insertion and eventual integration of immigrants. It therefore shows the contribution of social capital in the migration and insertion into ... -
Mineralogy and chemical mobility in a weathered ash dump site, South Africa
(University of the Western Cape, 2010)Coal fly ash generated from coal fired plants poses potential health risks to humans and plants in the environment due to the surface enrichment of the ash with various toxic trace elements during combustion. Only a small ... -
Mining a Chinese hyperthermophilic metagenome
(University of the Western Cape, 2007)Metagenomic sequencing of environmental samples provide direct access to genomic information of organisms within the respective environments. This sequence information represents a significant resource for the identification ... -
miRNAMatcher: High throughput miRNA discovery using regular expressions obtained via a genetic algorithm
(University of the Western Cape, 2008)In summary there currently exist techniques to discover miRNA however both require many calculations to be performed during the identification limiting their use at a genomic level. Machine learning techniques are currently ... -
