The adenomatous polyposis coli (APC) and p53 gene status in South African oesophageal cancer patients
(University of the Western Cape, 1996)
Oesophageal cancer is the most conmon cause of cancer-related deaths in black males in South Africa. In an effort to understand the molecular nature of oesophageal carcinogenesis in South Africa, two tumour suppressor ...
Singular integral equations and realization: A survey of the state space method
(University of the Western Cape, 1996)
Different methods for solving singular integral equations exist. One of the most recent methods is the so-called state space method. This method is based on the fact that a rational matrix function VV(^) which is analytic ...
Mineralogy and chemical mobility in a weathered ash dump site, South Africa
(University of the Western Cape, 2010)
Coal fly ash generated from coal fired plants poses potential health risks to humans and plants in the environment due to the surface enrichment of the ash with various toxic trace elements during combustion. Only a small ...
The effects of clipping and burning on the allocation of total nonstructural carbohydrates and selected mineral nutrients in Imperata cylindrica (L.) Raeuschel
(University of the Western Cape, 1999)
The rhizomatous grass, Imperata cylindrica, occurs in the Cape Flats Nature Reserve (CFNR), South Africa. It is recognised globally as a weed of crop plants. The response of this weed to defoliation, in the forms of clipping ...
Mathematical epidemiology of malaria disease transmission and its optimal control analyses
(University of the Western Cape, 2010)
In this thesis, we present and analyse an SEIR (susceptible-exposed infectious-recovered) model for malaria disease transmission. The model consists treatment and control strategies such as the use of bed nets and spray ...
A case study of university students' experiences of introductory physics drawn from their approaches to problem solving
(University of the Western Cape, 2001)
This thesis explores the experience of leaming physics through a particular medium: problem-solving, which is seen by many educators as the primary medium in which physics is learnt at university. Situating itself within ...
Tumour suppression and subdual of cancer (tussc) in elephants: An in vitro study to shed light on Peto’s paradox
(University of the Western Cape, 2022)
Logic would suggest that cancer incidence is related to body mass and longevity. Gigantic
animals such as elephants with a longer lifespan (more lifetime of cell divisions) and a larger
body size (more cells) will have ...
Computation of the character tables of certain group extensions
(University of the Western Cape, 1997)
In this chapter some basic theory on group extensions is first given in section 1.1 and then a method for finding the conjugacy classes of group extensions is described in section i.2. In section 1.3 we look at an example ...
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)
This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ...
A decision-making framework for groundwater management in arid zones (with a case study in Namaqualand).
(University of the Western Cape, 2004)
The main aim of the work on which this thesis is based was to develop a framework for sustainable management of groundwater resources in arid zones with emphasis on Namaqualand in the north western region of South Africa. ...
