Development and characterization of pro-apoptotic drug candidates for anticancer drug discovery
(2013)
Cancer is one of the leading causes of death worldwide. According to the WHO, cancer accounted for 7.4 million deaths world wide in 2004. The metallo-compound cisplatin has been used for years as an effective antitumor ...
Synthesis and characterization of silver nanoparticles for photovoltaic application
(2013)
With an increase in the amount of harmful carbon emissions in the atmosphere as well as a decrease in the availability of fossil fuels, there is a relatively high demand for alternate energy devices. Solar cells have become ...
Hydrophilic Polysulfone-Hydrogel Membrane Material for Improved Nanofiltration in Wastewater Treatment
(University of the Western Cape, 2013)
Over the last decade polysulfone membranes have been demonstrated to be one
of the best membrane types in wastewater treatment, especially in ultrafiltration,
owing to its mechanical robustness, structural and chemical ...
Low temperature tungsten trioxide nano/micro-systems for applications in gas sensing and electrochromism
(2013)
In this work we primarily set out to investigate the technique of Aqueous Chemical Growth as a means of producing WO3 thin films that find applications in gas sensing and electrochromism. For the first time we demonstrated ...
Genomic instability in South African breast cancer patients
(2013)
Breast cancer (BC) is one of the most common malignancies in women. Death results from treatment failure and metastatic disease. Thousands of lives might be saved if it was possible to detect and eliminate occult metastatic ...
Long-term vegetation monitoring – a 33 year record from table mountain
(2013)
Nearly 40 years ago McLachlan and Moll highlighted the need for a well-defined path system on the Western Table of Table Mountain in the immediate vicinity of the Upper Cable Station (UCS). At that time the numbers of ...
A hierarchical modelling approach to identify factors associated with the uptake of HIV counselling and testing, maternal health services, and prevention of mother to child HIV transmission programme services among post-partum women in Ethiopia
(2013)
The HIV/AIDS epidemic remains an unbeaten challenge that affects all parts of the
global population. Since the identification of the epidemic in the early 1980s, nearly
58 million people have become infected with the ...
Petrophysics and fluid mechanics of selected wells in Bredasdorp Basin South Africa
(2013)
Pressure drop within a field can be attributed to several factors. Pressure drop occurs when fractional forces cause resistance to flowing fluid through a porous medium. In this thesis, the sciences of petrophysics and ...
Investigation of anti-cancer potential of Pleiocarpa pycnantha leaves
(University of the Western Cape, 2013)
The Apocynaceae family is well known for its potential anticancer activity. Pleiocarpamine isolated from the Apocynaceae family and a constituent of Pleiocarpa pycnantha has been reported for anti-cancer activity. Prompted ...
Can bio fortified plants accumulate trace elements essential to the growth and development of humans?
(University of the Western Cape, 2013)
Micronutrient and trace element deficiencies are a problem affecting nearly two billion
people globally. The people affected the most by these deficiencies are those living in poor
and rural communities in the developing ...
