Polypyrrole supports for direct alcohol fuel cells.
(University of Western Cape, 2021)Anode catalysts are one of the key components of direct alcohol fuel cells (DAFCs). They play a huge role in the alcohol oxidation reaction (AOR) that occurs on the anode side. Palladium (Pd) supported on carbon material ... -
Population and Physiological Studies of selected Geophytics Species of Lowland Coastal Fynbos in the Southwestern Cape
(University of the Western Cape, 1990)Population and physiological studies were conducted in coastal fynbos in the South-western Cape. Minor ecophysiological studies were also conducted such as the soil moisture content and pH. Two species, viz. Haemanthus ... -
Population pharmacokinetics of terizidone and cycloserine in patients with drugresistant tuberculosis
(University of the Western Cape, 2019)Introduction: Drug-resistant tuberculosis remains a major world health problem and one of the leading cause of death worldwide. Despite adequate adherence to antituberculosis drugs by patients, the emergence of drug-resistance ... -
Population structure and demographics in Nigerian populations utilizing Y-chromosome markers
(University of the Western Cape, 2014)Nigeria is peopled by ethnically and linguistically diverse populations of which little were known until the last few millennial. The absence of major natural geographical barrier increases the possibility of the populations ... -
Pore pressure prediction and direct hydrocarbon indicator: insight from the southern pletmos basin, offshore South Africa
(University of the Western Cape, 2014)An accurate prediction of pore pressure is an essential in reducing the risk involved in a well or field life cycle. This has formed an integral part of routine work for exploration, development and exploitation team in ... -
