Synthesis and characterization of nanofluids for cooling applications
(University of the Western Cape, 2006)
Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in numerous industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles ...
Regional groundwater monitoring in the Olifants-Doorn water management area
(University of the Western Cape, 2006)
The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the Olifants-Doorn Water Management (WMA) area. The general approach was to attempt ...
Phytochemical studies of Helichrysum patulum
(University of the Western Cape, 2006)
Since Helichrysum is known by the indigenous people of Africa for therapeutic properties, such as against colds, flu and wounds, the aim of this study was to focus on the patulum species found predominantly in the Western ...
The ecology of tadpoles in a temporary pond in the Western Cape with comparisons to other habitats
(University of the Western Cape, 2006)
This work centered on the tadpoles in a temporaray pond in the middle of Kenilworth racecourse, Cape Town, South Africa. Trapping was carried out over two wet seasons and five species were found. The racecourse was selected ...
Location-based estimation of the autoregressive coefficient in ARX(1) models
(University of the Western Cape, 2006)
In recent years, two estimators have been proposed to correct the bias exhibited by the leastsquares (LS) estimator of the lagged dependent variable (LDV) coefficient in dynamic regression models when the sample is finite. ...
The electrogeneration of hydroxyl radicals for water disinfection
(University of the Western Cape, 2006)
This study has shown that OHË radicals can be generated in an Fe/O2 cell from the electrode products via Fenton’s reaction and used for water disinfection. The cell system in which the experiments were carried out ...
Systematic approach to protein crystallization: emphasis on Vaccinia virus complement control protein (VCP)
(University of the Western Cape, 2006)
This work examined the systematic approach to protein crystallization, exploring some of the techniques that have been developed to enhance the success rate of crystallization. The work was centered on two proteins; namely ...
Stakeholder accountability in water demand management in South-east Botswana
(University of the Western Cape, 2006)
Botswana's population and water demand are growing at a high rate particularly in the dry south eastern part of the country. In 1999, a Water Conservation Policy and Strategy framework document was formulated to guide a ...
Waiting to die: staging of HIV positive people at the first HIV test - Region A, Nelson Mandela Metropole (January 1991-April 2000)
(University of the Western Cape, 2006)
This project suggested that HIV people in Region A (Nelson Mandela Metropole, formerly Port Elizabeth) health district of the Eastern Cape, seek HIV testing when they are already in stages three (late disease) and four ...
Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
Over the past 40 years, research pertaining to membrane technology has lead to the development of a wide range of applications including beverage production, water purification and the separation of dairy products. For the ...
