The feasibility of high resolution, three-dimensional reconstruction of metal-coated surfaces in structural biology
(2006)
Life is an emergent property of a complex network of interacting cellular-machines. Three-dimensional (3D), cellular structure captured at supra-atomic resolution has the potential to revolutionise our understanding of the ...
End-to-end single-rate multicast congestion detection using support vector machines
(2008)
IP multicast is an efficient mechanism for simultaneously transmitting bulk data to multiple receivers. Many applications can benefit from multicast, such as audio and videoconferencing, multi-player games, multimedia ...

The need for a fundamental change in our approach to water management in South Africa
is largely underpinned by the country's Constitution (Act 108 of 1996). Section 24 in
Chapter 2 of the Constitution is perhaps the ...
Mononuclear and multinuclear salicylaldimine metal complexes as catalysts precursors in the oxidation of phenol and cyclohexene
(2009)
In this thesis typical homogeneous and dendritic immobilized catalysts derived from
salicylaldimines were investigated as catalysts for the oxidation of hydrocarbons using
hydrogen peroxide as oxidant under aerobic ...
Comparing South African financial markets behaviour to the geometric Brownian Motion Process
(University of the Western Cape, 2008)
This study examines the behaviour of the South African financial markets with regards to the Geometric Brownian motion process. It uses the daily, weekly, and monthly stock returns time series of some major securities ...
Seasonal effects on the feeding ecology and habitat of Chersina Angulata in the South Western Cape
(University of the Western Cape, 2008)
Nearly one-third of the world’s tortoises live in South Africa, but little is known about their habitat requirements and feeding ecology. Chersina angulata, the angulate tortoise, is endemic to southern Africa, with a ...
Policy based network management of legacy network elements in next generation networks for voice services
(University of the Western Cape, 2002)
Telecommunication companies, service providers and large companies are now
adapting converged multi-service Next Generation Networks (NGNs). Network
management is shifting from managing Network Elements (NE) to managing ...
Cloning, expression and characterisation of Amidase Genes from a psychrotolerant Nesterenkonia isolate
(University of the Western Cape, 2009)
A nitrile and amide hydrolysing Nesterenkonia sp. was isolated from Antarctic soil and was characterised as a psychrotolerant, halotolerant and alkaliphilic extremophile. Amidases are widely distributed in both prokaryotic ...
Cardiovascular effects of (13S)-9_, 13_- epoxylabda-6_(19), 15(14)diol dilactone, a diterpenoid isolated from the organic extract of leonotis leonurus leaves, in anaesthetized normotensive rats
(2009)
Plants used in traditional medicines have served as sources of some of the drug compounds used in medicines today, and could still serve as leads for then development of new drugs to treat existing chronic diseases such ...
