Demographic and health impact of alcohol and tobacco in Cameroon and Albania
(University of the Western Cape, 2022)The aim of this article is to illustrate a comparative analysis of the prevalence of alcohol and tobacco use and its impact on demographic and health indicators in Cameroon and Albania. Tobacco is the leading cause of ... -
Demographic aspects of migrants’ access to drinkable water in South Africa: Insight from the 2011 census
(University of the Western Cape, 2020)The issue of migrants’ access to drinkable water is a developmental issue. From a fundamental research view point, this study aims to explore the circumstances in which migrants access water across metropolitan and ... -
Dendritic poly(3-hexylthiophene) star copolymer systems for next generation bulk heterojunction organic photovoltaic cells
(University of the Western Cape, 2018)The continuous increase in energy consumption and decrease in fossil fuels reserves are a primary concern worldwide; especially for South Africa. Therefore, there is an urgent need for alternative energy resources that ... -
Deposition and structural properties of silicon carbide thin films for solar cell applications.
(University of the Western Cape, 2014)The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell applications has been studied. The films were characterized for structural ... -
Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ... -
Description and assessment of neuston 1 communities present in the South Indian Ocean
(University of the Western Cape, 2022)Animal communities living at the sea-surface are relatively poorly known, despite the fact that this biotope is globally distributed, it acts as an important nursery area for many commercially important taxa and supports ... -
Design and evaluation of fast dispersible tablets of lamivudine using selected natural superdisintegrants
(University of the Western Cape, 2018)Fast dispersible tablets (FDTs) are solid single-unit dosage forms that are placed in the mouth and allowed to disperse or dissolve in the saliva without the need of water. The basic approach to formulating FDTs consists ... -
Design and implementation of a credible blockchain-based e-health records platform
(University of Western Cape, 2020)With the development of information and network technologies, Electronic Health Records (EHRs) management system has gained wide spread application in managing medical records. One of the major challenges of EHRs is the ... -

The design and simulation of a new experimental set up to measure nuclear level lifetimes
(University of the Western Cape, 2016)Measurements of nuclear level lifetimes are an important aspect of experimental nuclear physics. Such measurements determine transition matrix elements for nuclear structure research and also provide the widths of relevant ... -
Design and synthesis of new scaffolds as antiproliferative agents and potential hsp90 inhibitors
(University of Western Cape, 2020)Natural products have been an important source of drugs and novel lead compounds in drug discovery. Their unique scaffolds have led to the synthesis of derivatives that continue to give rise to medicinally relevant agents. ... -
Design and synthesis of polycyclic amine derivatives for sigma receptor activity
(2013)New therapeutic strategies are needed for a diverse array of poorly understood neurological impairments. These include neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, and the psychiatric ... -
Design of a helium-6 production target for the iThemba LABS Radioactive-ion Beam Facility
(University of the Western Cape, 2018)It is well known, that there is a severe lack of information available pertaining to neutron rich nuclei, specifically of those nuclei with mass numbers ≥ 60. These neutron rich nuclei are not easy to access in current ... -
Design of a thermoresponsive hydrogel for enhanced intratumoral permeation of a chemotherapeutic agent in oral squamous cell carcinoma
(University of the Western Cape, 2023)Introduction: Oral squamous cell carcinoma is the most common and aggressive cancer occurring in the oral cavity. Intravenous chemotherapy remains a pivotal part of treatment for the disease; however, these drugs cause ... -
