Chemical interactions and mobility of species infly ash-brine co-disposal systems
(University of the Western Cape, 2010)
The primary aim of these coal fired industries for co-disposing fly ash and brine was to use the fly ash as a sustainable salt sink. It is therefore important to study the interaction chemistry of the fly ash-brine systems ...
One-Dimensional nanostructured polymeric materials for solar cell applications
(University of the Western Cape, 2010)
This work entails the preparation of various polyanilines with different morphologies and their application in photovoltaic solar cells. Zinc oxide (ZnO) with one-dimensional and flower-like morphology was also prepared ...
The use of mobile phones as service-delivery devices in sign language machine translation system
(University of the Western Cape, 2010)
This thesis investigates the use of mobile phones as service-delivery devices in a sign language machine translation system. Four sign language visualization methods were evaluated on mobile phones. Three of the methods ...
Fabrication and characterization of a solar cell using an aluminium p-doped layer in the hot-wire chemical vapour deposition process
(University of the Western Cape, 2010)
When the amorphous silicon (a-Si) dangling bonds are bonded to hydrogen the concentration of the dangling bond is decreased. The resulting film is called hydrogenated amorphous silicon (a-Si:H). The reduction in the dangling ...
Stellar masses of star forming galaxies in clusters
(University of the Western Cape, 2010)
We determine the stellar mass of star forming galaxies in the X-ray luminous cluster MS 0451.6-0305 at z ∼ 0.54. The stellar masses are estimated from fitting model spectral energy distributions (SEDs) to deep, optical ...
A technique for the evaluation of free and open source e-learning systems
(University of the Western Cape, 2010)
Evaluating software is a universal and complex problem. The question is: how should software be selected and adopted, or rather, which of the software packages is the most suitable for a specific environment? Extensive ...
Towards stimuli-responsive functional nanocomposites: smart tunable plasmonic nanostructures Au-VO2
(University of the Western Cape, 2010)
The fascinating optical properties of metallic nanostructures, dominated by collective oscillations of free electrons known as plasmons, open new opportunities for the development of devices fabrication based on noble metal ...
The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)
In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ...
A mathematical modeling of optimal vaccination strategies in epidemiology
(University of the Western Cape, 2010)
We review a number of compartmental models in epidemiology which leads to a nonlinear system of ordinary differential equations. We focus an SIR, SEIR and SIS epidemic models with and without vaccination. A threshold ...
Molecular Characterisation of the Brassinosteroid, Phytosulfokine and cGMP-dependent Responses in Arabidopsis thaliana
(University of the Western Cape, 2010)
In this thesis, we have firstly cloned and expressed the domains that harbours the putative catalytic GC domain in these receptor molecules and demonstrate that these molecules can convert GTP to cGMP in vitro. Secondly, ...
