Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
(University of the Western Cape, 2011)
In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ...
Numerical singular perturbation approaches based on spline approximation methods for solving problems in computational finance
(University of the Western Cape, 2011)
Options are a special type of derivative securities because their values are derived from the value of some underlying security. Most options can be grouped into either of the two categories: European options which can be ...
Study of magnetic properties of nanostructures on self-assembled patterns
(University of the Western Cape, 2010)
In the current study, we give a report when oxalic acid was used as an electrolyte to synthesize an AAO template with hexagonal pore array. Optimum parameters were observed as 0.4 M of oxalic acid, anodizing voltage of 45 ...
Browser-based and mobile video communication alternatives for Deaf people
(University of the Western Cape, 2011)
This thesis offers some prototypes to provide browser-based and mobile video communication services for Deaf people and evaluates these prototypes. The aim of this research is to identify an acceptable video communication ...
Petrophysical evaluation of the Albian Age gas bearing sandstone reservoirs of the O-M field, Orange Basin, South Africa
(University of the Western Cape, 2010)
Petrophysical evaluation of the Albian age gas bearing sandstone reservoirs of the O-M field, Offshore South Africa has been performed. The main goal of the thesis is to evaluate the reservoir potentials of the field through ...
Mobile presentations with interactive chat for m-Learning
(University of the Western Cape, 2010)
Using presentations in an m-Learning environment enables delivery of rich content to a mobile phone learner. This study investigated how to prepare and stream presentations from a desktop computer to a mobile phone in ...
Use of antioxidant activity and flavonoid levels to assess the quality of commercially available solid dose Sutherlandia frutescens products
(University of the Western Cape, 2010)
The overall aims of this project were to assess the pharmaceutical quality and consistency of commercially available solid dose Sutherlandia frutescens containing products (viz. tablets & capsules) by exploring the use of ...
Multicomponent catalysts for methanol electro-oxidation processes synthesized using organometallic chemical vapourde position technique
(University of the Western Cape, 2011)
In this study, the OMCVD method is demonstrated as a powerful, fast, economic and environmental friendly method to produce a set of PGMelectrocatalysts with different supports, metal content and metal alloys in one step ...
Lichen thermal sensitivities, moisture interception and elemental accumulation in an arid South African ecosystem
(University of the Western Cape, 2010)
Elevated temperatures accompanying climate warming are expected to have adverse effects on sensitive lichen species. This premise was examined by measuring the sensitivity of different lichen species to elevated temperatures ...
Identification and characterisation of novel cellulolytic genes using metagenomics
(University of the Western Cape, 2010)
Metagenomics has been successfully used to discover novel enzymes from uncultured microorganisms in the environment. In this study, metagenomic DNA from a Malawian hot spring soil sample was used to construct a fosmid ...
