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) ...
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. ...
Case study of bird streamer caused transient earth faults on a 275KV transmission grid.
(2001)
This thesis discusses the results of an investigation that was initiated in January
1996 to determine the root cause of the increasing fault trend in respect of
transient earth faults on the 275 kV transmission grid ...
Cordless linear synchronous motor material handling system for computer integrated manufacturing.
(2000)
Advanced material handling systems' impact on flexible manufacturing systems (FMS) have
increased the efficiency and work rate over conventional manufacturing assemblies. The
interaction of automated guided vehicles ...
Women and technology in the marginalized rural communities : case studies from Kwazulu-Natal.
(2004)
Generally, rural women have lesser access to technologies that are vital in progressing
with their tasks due to gender dimensions linked to patriarchy that were perpetuated by
apartheid, which promoted male migration and ...
Lattice-structure based adaptive MMSE detectors for DS-CDMA systems.
(2001)
There has been significant interest in the research community on detectors for DS-CDMA
systems. The conventional detector, which detects users ' data bits, by using a filter matched to the
users' spreading codes, has two ...
Pharmacological investigation of some trees used in South African traditional medicine.
(2005)
South Africa is home to a wide diversity of cultural groups, all of which
utilize the flora for a variety of purposes. This is true with regard to traditional
medicine systems which are similar to those of the rest of ...
Regulation of hyperhydricity in Aloe polyphylla propagated in vitro.
(2009)
Micropropagation of Aloe polyphylla, an endangered species with a high ornamental and medicinal value, is an important part of its conservation. However, the in vitro culture was hindered by the phenomenon of hyperhydricity. ...
The fate of non-limiting solutes and the processes of solute retention in the uMkhuze Wetland system, KwaZulu-Natal, South Africa.
(2008)
Wetlands have long been recognised as enhancing the quality of inflowing waters, particularly regarding the plant macronutrients nitrogen and phosphorus. Any research into non-limiting solutes has largely been of a 'black ...
The evaluation of pressure distribution and bulk density models for infield agriculture and forestry traffic.
(2006)
There is evidence that soil compaction, through the use of mechanised equipment, causes detrimental effects to soil quality and reduces long-term productivity of soils. For economic reasons, farmers need to purchase larger, ...
