Discovery of anti-mycobacterial natural products from South African marine algae
(University of the Western Cape, 2019)Tuberculosis is a communicable disease which affects millions of people around the world. Although the case reports are declining, the eradication rate of this disease is far too slow. Natural products have played a key ... -
Discovery of antibacterial lead compounds from marine organisms
(University of the Western Cape, 2020)Marine organisms including algae and bacteria are known to produce chemically diverse secondary metabolites for survival purposes in the marine environment. Scientists have identified some of these natural products as ... -
Discovery of biomolecules from South African marine sponge symbionts through Metagenomic studies
(University of the Western Cape, 2018)Marine sponges are known to harbour diverse microorganisms which have been proposed to be involved in the synthesis of most of the natural compounds derived from sponges. However, only about 1% of these microorganisms can ... -
Discovery of cytotoxic natural products from South African marine sponges

Discrete time methods of pricing Asian options
(University of Western Cape, 2014)This dissertation studies the computation methods of pricing of Asian options. Asian options are options in which the underlying variable is the average price over a period of time. Because of this, Asian options have a ... -
Discriminative eradication of cancer cells using quantum dots functionalised with peptide-directed delivery of a pro-apoptotic peptide
(2013)The therapeutic goal of cancer treatment is to trigger selective cell death in cancer cells. To eliminate cancerous cells effectively, the anti–cancer drugs must be targeted to the affected cells. However, anti–cancer drugs ... -
Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)Observations of galaxies at di↵erent wavelengths have shaped our understanding of their formation and evolution through time. The commonly derived parameters, such as stellar mass and star formation rate (SFR), rely on ... -
Disposal of unused medicines from households in Cape Town
(University of Western Cape, 2019)Evidence indicates that most South African households do not dispose of unused medicines in the manner prescribed by the medicine’s regulatory authority. This trend is not unique to South Africa, but several developing ... -
Disposal Practices for Unwanted Medicines from Households in Johannesburg
(University of the Western Cape, 2017)A mixed research method was used where quantitative research facilitated qualitative research. Three questionnaires were drafted and distributed by email to respondents in the Johannesburg area. One questionnaire was for ... -
Dissolution and antiviral activity of a novel nevirapine formulation
(University of the Western Cape, 2014)The author’s objective was to follow the product life-cycle process of a novel antiretroviral, nevirapine formulation in South Africa, to generate and compile data to pursue market registration. Five supramolecular ... -
