Electrochemical kinetics and sensing of conjugated dienes in acetonitrile
(University of the Western Cape, 2011)
This thesis focuses on the electroanalysis of some dienes (2-methyl-1.3-butadiene (MBD), tran-1.3-pentadiene (PD), 1.3-cyclohexadiene (CHD) and 3-cyclooctadiene (COD)) found in gasoline and the development of simple ...
Chemical, physical and morphological changes in weathered brine slurried coal fly ash
(University of the Western Cape, 2011)
Energy production from coal comes with an environmental cost because of the toxic waste produced during coal combustion such as coal ash and brine which are potential water and soil pollutants. Coal ash and brine contain ...
Sorption properties of natural zeolites for the removal of ammonium and chromium ions in aqueous solution
(University of the Western Cape, 2011)
There are huge amount of natural clinoptilolite available in South Africa which can be utilised for wastewater treatment of ammonia and chromium if their characteristics are properly known. However, these deposits have not ...
Actinobacterial diversity of the Ethiopian Rift Valley lakes
(University of the Western Cape, 2011)
The class Actinobacteria consists of a heterogeneous group of filamentous, Gram-positive bacteria that colonise most terrestrial and aquatic environments. The industrial and biotechnological importance of the secondary ...
Electrochemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Applications of electrochemiluminescent conjugated polymers offer promising solutions in addressing the problem of light emitting devices. However, the challenging problems that hamper their application in light emitting ...
Pharmaceutical formulation and in-vitro testing of Dioxy MP 14 (stabilised chlorine dioxide) against mycobacteria tuberculosis
(University of the Western Cape, 2011)
This study was based on Dioxy MP 14 (DMP), a brand of stabilized chlorine dioxide (SCD). The active pharmaceutical ingredient (API) of DMP is chlorine dioxide (CD) which is a potent oxidant and biocide. These properties ...
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 ...
Assessing the relationship between youth capabilities and food security : a case study of a rainwater harvesting project
(University of the Western Cape, 2011)
The National Water Act of 1998 provides the policy framework for stakeholder participation and the engagement of stakeholders closest to the resource on which they depend to be involved in developing and managing their ...
Characterisation of a lignocellulosic degrading bacillus strain isolated from thermophilic compost
(University of the Western Cape, 2011)
The negative environmental impact of fossil fuels and growing concerns about petroleum supplies has driven the search for alternative, renewable transportation fuels. An 'ideal' fuel replacement would be a biofuel produced ...
Recognition of facial action units from video streams with recurrent neural networks : a new paradigm for facial expression recognition
(University of the Western Cape, 2011)
This research investigated the application of recurrent neural networks (RNNs) for recognition of facial expressions based on facial action coding system (FACS). Support vector machines (SVMs) were used to validate the ...
