Paediatric non-alcoholic fatty pancreas disease and aortic intimal medial thickness: A study identifying potential fatty infiltration of the pancreas and its association with aortic IMT in children exposed to teratogens during pregnancy
(University of the Western Cape, 2020)The incidence of non-communicable diseases is increasing worldwide, with South Africa being no exception. Non-communicable diseases are classified as non-infectious and are often referred to as lifestyle diseases as they ... -
Pairings of Binary reflexive relational structures
(University of the Western Cape, 2008)The main purpose of this thesis is to study the interplay between relational structures and topology , and to portray pairings in terms of some finite poset models and order preserving maps. We show the interrelations ... -

Palladium surface-modified rare earth metal-based ab5 type hydride-forming materials
(University of the Western Cape, 2008)Driven by mounting standards of living and a growing population, South African energy consumption is expected to increase dramatically within the next decade. The increased demand for more energy will require enormous ... -
Palladium telluride quantum dots biosensor for the determination of indinavir drug
(2013)Indinavir is a potent and well tolerated protease inhibitor drug used as a component of the highly active antiretroviral therapy (HAART) of HIV/AIDS, which results in pharmacokinetics that may be favourable or adverse. ... -
The paracrine effect of normoxic and hypoxic cancer secretions on blood-brain barrier endothelial cells
(University of the Western Cape, 2022)Cancer is the most common leading cause of death worldwide. Glioblastoma and breast cancer are the most aggressive solid tumour. The survival rate of these tumours depends on their ability to progress and spread. These ... -
The paradox of enrichment in predator-prey systems
(University of Western Cape, 2020)In principle, an enrichment of resources in predator-prey systems show prompts destabilisation of a framework, accordingly, falling trophic communication, a phenomenon known to as the \Paradox of Enrichment" [54]. After ... -
Parameters affecting the production of fumonisin B1 by fusarium verticillioides in culture
(University of the Western Cape, 2001)Fi1sarium verticillioides is a very important mycotoxin-produeing fungus associated with maize. Fverticillioides produces a group of mycotoxins known as fumonisins under suitable environmental conditions. A series of studies ... -
Parametric deconvolution for a common heteroscedastic case
(University of the Western Cape, 2016)There exists an extensive statistics literature dealing with non-parametric deconvolution, the estimation of the underlying population probability density when sample values are subject to measurement errors. In parametric ... -
Participation of African immigrants in the labour force of South Africa: Insights from the 2001 population census
(University of the Western Cape, 2008)The study examines the participation of African immigrants in the South African labour force with the central question revolving around whether the immigrants create jobs through the establishment of their own businesses ... -
Participation of African migrants in the labour force of South Africa : are there structural changes from 2001 to 2011?
(University of the Western Cape, 2015)This thesis examines the distribution of African migrants across the different segments of the labour force in South Africa. The specific objective of this study is to demonstrate that there has been structural changes ... -
The partitioning of evapotranspiration in apple orchards from planting until full-bearing age and implications for water resources management
(University of Western Cape, 2021)Orchard evapotranspiration (ET) is a complex flux which has been the subject of many studies. It often includes transpiration from the trees, cover crops and weeds, evaporation from the soil, mulches, and other orchard ... -
