Construction and analysis of efficient numerical methods to solve mathematical models of TB and HIV co-infection
(University of the Western Cape, 2011)The global impact of the converging dual epidemics of tuberculosis (TB) and human immunodeficiency virus (HIV) is one of the major public health challenges of our time, because in many countries, human immunodeficiency ... -
Construction and analysis of exponential time differencing methods for the robust simulation of ecological models
(University of Western Cape, 2021)In this thesis, we consider some interesting mathematical models arising in ecology. Our focus is on the exploration of robust numerical solvers which are applicable to models arising in mathematical ecology. To begin ... -
Construction of an enzyme-free electrochemical sensor based on Ag-Fe2O3/POM/RGO novel nanocomposite for hydrogen peroxide detection
(University of the Western Cape, 2018)The motivation to determine H2O2 lies in the fact that this chemical species plays a crucial role in diverse fields of practise such as cosmetic, food, diagnostic, pharmaceutical, clinical and environmental protection ... -
Content levels, in vitro dissolution and predicted bioavailability of flavonoids from Sutherlandia frutescens leaf powder and aqueous extracts
(University of the Western Cape, 2015)Various formulations of the popular South African medicinal plant, Sutherlandia frutescens,are commercially available, with no documented specifications for quality assessment. With plans already underway for a clinical ... -
Context-awareness for adaptive information retrieval systems
(University of the Western Cape, 2014)This research study investigates optimization of IRS to individual information needs in order of relevance. The research addressed development of algorithms that optimize the ranking of documents retrieved from IRS. In ... -
Contraception and unmet-needs in Africa
(University of the Western Cape, 2009)The first objective of this study is to show if diffusion of contraception in areas of traditional high fertility has gone through profound changes. Indeed, we would like to know if contraceptive behaviours have evolved ... -
Cooperative data muling using a team of unmanned aerial vehicles
(University of the Western Cape, 2019)Unmanned Aerial Vehicles (UAVs) have recently o ered signi cant technological achievements. The advancement in related applications predicts an extended need for automated data muling by UAVs, to explore high risk places, ... -
Coordination polymers as heterogeneous catalysts for oxidation reactions
(University of the Western Cape, 2014)This study describes the synthesis and characterisation of coordination polymers complexes of Cu(II) and VO(IV) with two polymeric ligands N,Nʹ -1,2-phenylene bis(5-methylenesalicylidenamine)(L1) and N,Nʹ -1,4-butylene ... -
Corporate Social Responsibility in the South African forestry industry – a Western Cape perspective
(University of the Western Cape, 2013)Globally plantation forestry plays a pivotal role in terms of timber production, ecological services and maintaining local livelihoods. In South Africa commercial forestry occupies a relatively small portion of the total ... -
The correlate between fertility and landholding among rural women in kenya: a multivariate analysis
(University of the Western Cape, 2013-05)The present study is an understanding of the relationship that exists between landholding and the reproductive behaviour of rural women in Kenya. Traditional women have rights to cultivate land as well as control income ... -
The correlation between the serious diseases affecting child mortality in Sierra Leone
(University of the Western Cape, 2011)Child mortality in Sierra Leone is the highest ranked in the world. Government officials and researchers have tried to understand how and why this has become such a big phenomenon in Sierra Leone. Researchers have come up ... -
Cosmology with HI intensity mapping: effect of higher order corrections
(University of the Western Cape, 2020)One of the main challenges of cosmology is to unveil the nature of dark energy and dark matter. They can be constrained with baryonic acoustic oscillations (BAO) and redshift space distortions, amongst others. Both have ... -
Cosmology with next generation radio telescopes
(University of the Western Cape, 2019)The next generation of radio telescopes will revolutionize cosmology by providing large three-dimensional surveys of the universe. This work presents forecasts using the technique 21cm intensity mapping (IM) combined ... -
Cost-Effectiveness of selecting an Enantiopure formulation over a racemic mixture
(University of the Western Cape, 2017)The aim of this study is to provide more information in terms of the cost-effectiveness of selecting an enantiopure formulation over a racemic mixture in the context of promoting rational use of medicines. This was done ... -
Coupling of single neutron configurations to collective core excitations in 162Yb using 163Yb
(University of the Western Cape, 2017)In odd-nuclei the single nucleon can couple to collective excitations of its even-even core nucleus . These collective excitations lie within the pairing gap and are therefore the lowest energy excitations of the core. Our ... -
