Pt Nanophase supported catalysts and electrode systems for water electrolysis
(University of the Western Cape, 2008)In this study novel composite electrodes were developed, in which the catalytic components were deposited in nanoparticulate form. The efficiency of the nanophase catalysts and membrane electrodes were tested in an important ... -
Public participation as governance the role of catchment forums in water governance Mluleki Matiwane
(2012)Catchment forums are concerned groups of people that come together on a voluntary basis in a specific area. They share the same goal and purpose to achieve - sustainable water resources management. These Catchment Forums ... -
Public sector spending in Nigeria: implications for poverty, demographic changes and millennium development goals target
(University of the Western Cape, 2015)Over the last two decades, budgetary allocations to both the Health and Education sectors have been on the increase in Nigeria, while a counter-factual feedback on its effects for various economic groups and distributional ... -
Purification and characterisation of plasmodium falciparum Hypoxanthine phosphoribosyltransferase
(University of the Western Cape, 2007)Malaria remains the most important parasitic disease worldwide. It is estimated that over 500 million infections and more that 2.7 million deaths arising from malaria occur each year. Most (90%) of the infections occur in ... -
Pyramlyl palladium(Il) complexes as phenylacetylene oligomerization and polymerization catalysts'
(University of the Western Cape, 2004)PyrazoM compounds have been extensively used to prepare metal complexes, but it is only recently that they have been investigated as catalysts for the polymerization of unsaturated hydrocarbons. In catalyzn11g the ... -
Pyrazole and pyrazolyl palladium(II) and platinum(II) complexes: synthesis and in vitro evaluation as anticancer agents
(University of the Western Cape, 2004)The use of metallo-pharmaceuticals, such as the platinum drugs, for cancer treatment illustrates the utility of metal complexes as therapeutic agents. Platinum group metal complexes therefore offer potential as anti-tumour ... -
