Manufacturing of synthetic soda ash
(University of the Western Cape, 2009)The aim of the project was to study the manufacturing of synthetic soda ash (sodium carbonate, Na2CO3) on an industrial scale. Currently all Soda ash that is used in South Africa for manufacturing glass is imported at a ... -
The map is not the territory: law and custom in ‘African freehold’: a South African case study
(2013)The thesis examines the characteristics of land tenure among African families with freehold title who trace their relationship to the land to their forebears who first acquired title in the mid-nineteenth century. The ... -
Mapping and identification of disease resistance candidate genes in three Malus populations using SSRs, DArT and Infinium SNP markers and Illumina sequencing technology
(University of the Western Cape, 2014)Apple scab, powdery mildew and woolly apple aphid are a major concern for apple breeders and producers. Control of these diseases is a significant economic and marketing priority for the South African apple industry. ... -
Mapping Break-Back Thrust Sequence Developments of the Orange Basin (offshore South Africa)
(University of the Western Cape, 2017)In the present study thrust sequence developments in the sediments below the deep-waters of the Orange Basin are mapped. Four seismic sections are interpreted from four different locations of the study area. The interpreted ... -
Marine bacteria as a potential source for novel antimicrobial compounds
(University of the Western Cape, 2020)The high rate of rediscovery of known compounds has led to a decline in the discovery of novel natural products. The high biodiversity of organisms growing in extreme conditions such as oceans has led to the increased ... -
Marine invertebrate sperm: Assessment of sperm quality using computer-aided sperm analysis
(University of Western Cape, 2020) -
Market segmentation and factors affecting stock returns on the JSE
(2008)This study examines the relationship between stock returns and market segmentation. Monthly returns of stocks listed on the JSE from 1997-2007 are analysed using mostly the analytic factor and cluster analysis techniques. ... -
Massively-Parallel Computational Identification of Novel Broad Spectrum Antivirals to Combat Coronavirus Infection
(University of the Western Cape, 2015)Given the significant disease burden caused by human coronaviruses, the discovery of an effective antiviral strategy is paramount, however there is still no effective therapy to combat infection. This thesis details the ... -
A matched case control study of the nutritional status of newly diagnosed tuberculosis patients and tuberculosis free contacts in Delft, Western Cape
(2011)Background: Malnutrition is a risk factor for the development of pulmonary tuberculosis (TB) and may be responsible for the premature deaths of patients with active disease. An adequate nutritional status may therefore be ... -
Maternal nicotine expose during gestation and lactation induce premature aging of the lungs of the offspring
(University of the Western Cape, 2009)Tobacco smoking remains one of the leading causes of death worldwide. Despite all the efforts made by governments, researchers and communities to educate women about the dangerous effects of tobacco smoke and nicotine, ... -
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 mathematical model for studying the impact of climate variability on malaria epidemics in South Africa
(University of the Western Cape, 2017)Malaria is most prevalent in tropical climates, where there are sufficient rainfall for mosquitoes to breed and conducive temperatures for both the mosquito and protozoa to live. A slight change in temperature can ... -
Mathematical model of performance measurement of defined contribution pension funds
(University of the Western Cape, 2015)The industry of pension funds has become one of the drivers of today’s economic activity by its important volume of contribution in the financial market and by creating wealth. The increasing importance that pension funds ... -
Mathematical modeling and analysis of HIV/AIDS control measures
(University of the Western Cape, 2012)In this thesis, we investigate the HIV/AIDS epidemic in a population which experiences a significant flow of immigrants. We derive and analyse a math- ematical model that describes the dynamics of HIV infection among the ... -
Mathematical modeling in the sustainable use of natural resources.
(University of the Western Cape, 2015)The sustainable use of natural resources is of utmost importance for every community. In particular, it is important for every given generation to plan in such a way that proper provision is made for future generations. ... -
Mathematical modeling of an epidemic under vaccination in two interacting populations
(University of the Western Cape, 2011)In this dissertation we present the quantitative response of an epidemic of the so-called SIR-type, in a population consisting of a local component and a migrant component. Each component can be divided into three classes, ... -
A mathematical modeling of optimal vaccination strategies in epidemiology
(University of the Western Cape, 2010)We review a number of compartmental models in epidemiology which leads to a nonlinear system of ordinary differential equations. We focus an SIR, SEIR and SIS epidemic models with and without vaccination. A threshold ... -

Mathematical modeling of population dynamics of HIV with antiretroviral treatment and herbal medicine
(University of Western Cape, 2014)Herbal medicines have been an important part of health and wellness for hundreds of years. Recently the World Health Organization estimated that 80% of people worldwide rely on herbal medicines. Herbs contain many ... -
Mathematical modeling of TB disease dynamics in a crowded population.
(University of the Western Cape, 2020)Tuberculosis is a bacterial infection which is a major cause of death worldwide. TB is a curable disease, however the bacterium can become resistant to the first line treatment against the disease. This leads to a disease ...
