Implementation of a proprietary CAD graphics subsystem using the GKS standard interface.
(1989)
This project involved porting a Graphical Software Package (GSP) from
the proprietary IDS-BO Gerber CAD system onto a more modern computer that
would allow student access for further study and development. Because of the ...
Design, modelling and simulation of 2 novel 6 DOF hybrid machines.
(2012)
Industrial robot arms are an essential part of automated manufacturing, and perform tasks
such as component assembly, welding, light machining, spray painting, etc. They are highly
repeatable, can be calibrated to be ...
An investigation of new heterogeneous hydrotalcite-like catalysts for the cis-dihydroxylation of olefins.
(2004)
The use of supported catalysts to essentially combine the positive traits offered by both homogeneous and heterogeneous catalysis has become a competitive field of research. In particular, hydrotalcite-like catalysts (HTIc) ...
End-pumped solid-state lasers.
(2010)
This dissertation consists of four sections, with the focus on near- and mid-infrared lasers using Yttrium Lithium Fluoride (YLF) crystals doped with various rare-earth ions as a gain medium. As introduction a general ...
Clifford-Fischer theory applied to certain groups associated with symplectic, unitary and Thompson groups.
(2012)
The character table of a finite group is a very powerful tool to study the groups and to prove
many results. Any finite group is either simple or has a normal subgroup and hence will be of
extension type. The classification ...
The biology, ecology and conservation of four Flufftail species, Sarothrura (Aves: Rallidae)
(1994)
The distribution, status, biology and ecology of four flufftail species were investigated in South Africa and Zimbabwe. The Redchested Flufftail is a successful and widely distributed species, occupying a wide range of ...
Pharmacological properties of members of the Sterculiaceae.
(2002)
There is a resurgence of interest in many countries in medicinal plants and their
curative properties (HARBORNE & BAXTER, 1993). Little work has previously
been conducted on the Sterculiaceae species, especially those ...
Biological activity of traditional medicinal plants used against venereal diseases in South Africa.
(2006)
Throughout the history of mankind, many infectious diseases have been
treated with plant extracts. Venereal infections are one such group and are regarded
as conditions that are highly responsive to traditional treatment. ...
In vitro propagation of Scilla natalensis planch.
(1999)
In South Africa, large quantities of Scilla natalensis are harvested from wild populations
and sold as traditional medicine, which is reducing the density, distribution and genetic
diversity of wild populations. The ...
Screening of traditionally used South African medicinal plants against Candida albicans.
(2003)
Candida species were discovered more than a century ago as a causative
organism of oral thrush. In HIV patients, the presence of oral candidiasis has
been shown to be the earliest opportunistic infection. Candidiasis ...
