Membrane module development for water recovery from humid gas
(University of the Western Cape, 2020)Over the past 5 years, South Africa has been experiencing a severe drought. This has caused industrial and agricultural processes, to compete for a limited supply of water. Since the economy relies mostly on agricultural ... -
Mercaptobenzothiazole-on-Gold Biosensor Systems for Organophosphate and Carbamate Pesticide Compounds
(University of the Western Cape, 2007)This study firstly reports the development, characterisation, and application of thick-film acetylcholinesterase (AChE) biosensors based on a gold electrode modified with a mercaptobenzothiazole (MBT) self-assembled monolayer ... -
Mercury leaching from dental amalgam fillings and its association with urinary zinc
(University of the Western Cape, 2019)Mercury (Hg) is an example of a toxic metal that is not essential for nutrition. It exists in organic and inorganic forms in seafood and vapour from dental amalgam fillings respectively. Elemental mercury (Hg0) from dental ... -
Mesh Free Methods for Differential Models In Financial Mathematics
(University of the Western Cape, 2011)Many problems in financial world are being modeled by means of differential equation. These problems are time dependent, highly nonlinear, stochastic and heavily depend on the previous history of time. A variety of financial ... -

Meta-Cayley Graphs on Dihedral Groups
(University of the Western Cape, 2017)The pursuit of graphs which are vertex-transitive and non-Cayley on groups has been ongoing for some time. There has long been evidence to suggest that such graphs are a very rarety in occurrence. Much success has been had ... -
Metagenomic analysis and characterization of microbial diversity from hydrothermal samples of El Tatio geyser field, Chile
(University of the Western Cape, 2012)The El Tatio geyser field (ETGF) is the largest known geothermal field in Chile, forming part of a wide spectrum of extremophilic habitats in the country. The ETGF is NaCl rich, with high concentrations of toxic elements ... -
Metagenomic approaches to gene discovery
(University of the Western Cape, 2006)The classical approach to gene discovery has been to culture micro-organisms demonstrating a specific enzyme activity and then to recover the gene of interest through shotgun cloning. The realization that these standard ... -
Metal assisted chemically etched silicon nanowires for application in a hybrid solar cell
(University of the Western Cape, 2018)Photovoltaic (PV) devices based on inorganic-organic hybrid active layers have been extensively studied for over a decade now. However, photoactive hybrid layers of material combinations such as rr-P3HT and SiNWs still ... -
Metal complexes based on monomeric and dendrimeric pyrrole-imine ligands as catalytic precursors
(University of the Western Cape, 2007)Over the recent past, organometallic chemistry has grown and the impact of catalytic applications in various chemical technologies has rapidly evolved from the realm of academic laboratories into full-scale industrial ... -
Metal modified mesoporous ZSM-5 as catalysts for the oligomerization of 1- hexene
(University of Western Cape, 2021)The use of diesel engines in vehicles and heavy machinery throughout the world has been slowly increasing in the past few decades. This has led to high demand for diesel and gasoline with high octane number. Diesel and ... -
Metal nanoparticle modified polysulfone membrane for water treatment
(University of the Western Cape, 2013)Membrane separation processes have been widely applied in the treatment of wastewater with polysulfone (PSF) polymer membrane being the most frequently used in ultrafiltration of wastewater due to its chemical and structural ... -
Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
(University of Western Cape, 2019)Without reverting to encapsulation, organic bulk - heterojunction solar cells can be protected from the oxidation of the highly reactive low work function cathode metal electrode, by the deposition of metal oxide buffer ... -
Metallic nanoparticles with polymeric shell: A multifunctional platform for application to biosensor
(University of the Western Cape, 2018)Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis (MTB) that usually affects the lungs leading to severe coughing, fever and chest pains. It was estimated that over 9.6 million people worldwide ... -
Metallodendrimers as catalysts for C-C coupling reactions
(2011)In this work, we describe the synthesis of ferrocenylimine and G1 dendrimeric N,N′ ligands, and their palladium(II) complexes. The ligands L1 – L4 were synthesized following Schiff base condensation reactions. The ... -
Method development for selective recovery of rare earths elements from phosphogypsum waste
(University of Western Cape, 2021)The need for rare earth elements (REEs) in current technologies has motivated countries with high imports dependency to search for alternatives sources. Several studies have been carried out to investigate the feasibility ... -
Methodological approach of the spatial distribution of maternal mortality in Burkina Faso and explanatory factors associated
(University of the Western Cape, 2013)Maternal mortality is one of the most important problems related to the reproductive health. This is why the reduction by three quarters of maternal mortality by 2015 has been fixed as target No. 5 of the Millennium ... -
Methods of optimizing investment portfolios
(2013)In this thesis, we discuss methods for optimising the expected rate of return of a portfolio with minimal risk. As part of the work we look at the Modern Portfolio Theory which tries to maximise the portfolio's expected ... -
Methylgyoxal signalling in Phaseolus vulgaris under phosphate deficiency
(UWC, 2020)In this study, we observed that phosphate (P) deficiency stunted plant growth and produced plants with poor morphological characteristics (yellow and small leaves). Furthermore, we treated plants with 0.8 mM (control) and ... -
