Realizing agricultural potential in land reform: The case of Vaalharts irrigation scheme in the Northern Cape Province
(University of the Western Cape, 2007)The effectiveness of the South African Land reform Programme has been at the centre of debates amonng land reform activists and within government. Empirical evidence shows that land reform has not only been moving at a ... -
Recognition of facial action units from video streams with recurrent neural networks : a new paradigm for facial expression recognition
(University of the Western Cape, 2011)This research investigated the application of recurrent neural networks (RNNs) for recognition of facial expressions based on facial action coding system (FACS). Support vector machines (SVMs) were used to validate the ... -
Recombinant expression and full backbone assignment of the human DWNN using heteronuclear NMR
(University of the Western Cape, 2005)The cellular levels of a number of proteins have been found to be regulated by the ubiquitin-proteasome pathway. In this pathway, proteins are covalently tagged (“ubiquitinated”) by ubiquitin, which acts as a signal for ... -
Recombinant expression of cytochrome P450-2D6 and its application in tamoxifen metabolism
(University of the Western Cape, 2018)Breast cancer is regarded as the most common form of cancer in women and it comprises of approximately 23 % of female cancers, while affecting women at any age range. For oestrogen receptor positive patients, tamoxifen is ... -
Recombinant expression of the pRb- and p53-interacting domains from the human RBBP6 protein for in vitro binding studies
(University of the Western Cape, 2004)This thesis describes the cloning and recombinant expression of domains from the human RBBP6 protein for future in vitro binding studies with pRb and p53. RBBP6 is a splicing-associated protein that is known to interact ... -

Reconstruction of gene regulatory networks of inflammation-associated genes in different clinical stages of diffuse large B-cell lymphoma
(University of the Western Cape, 2022)Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous malignancy that is driven by complex gene regulatory networks (GRNs). Numerous genes exert distinct effects on the progression and therapeutic outcome of DLBCL. ... -
Reconstruction of major male and female lineages of the kensington Muslim community
(University of the Western Cape, 2010)The earliest Cape Muslims were brought to the Cape from Africa and Asia from 1652 to 1834. They were part of an involuntary migration of slaves, political prisoners and convicts, and they contributed in the ethnic diversity ... -
Reconstruction of major male and female lineages of the Strand Muslim community
(University of the Western Cape, 2010)Initially, a pilot study was carried out in order to reconstruct the major paternal and maternal lineages of the Muslim population living in the Cape metropolitan area. The Study has shown the ability of molecular genetic ... -
Reconstruction of the ionization history from 21cm maps with deep learning
(University of the Western Cape, 2020)Upcoming and ongoing 21cm surveys, such as the Square Kilometre Array (SKA), Hydrogen Epoch of Reionization Array (HERA) and Low Frequency Array (LOFAR), will enable imaging of the neutral hydrogen distribution on ... -
Recovery of SiO₂ and Al₂O₃ from coal fly ash
(University of the Western Cape, 2016)Most of the world's energy production is still mainly achieved by the combustion of coal in power stations. Coal fly ash is the inevitable waste product that accumulates to metric ton volumes each year. These vast volumes ... -
Red palm oil as a therapeutic agent in triple-negative breast cancer patients
(University of the Western Cape, 2020)Purpose: Breast cancer is one of the most frequent and fatal diseases women all around the globe are challenged with today. In women, breast cancer has the highest mortality rate of all cancers and the incidence rate is ... -
Redshift-space distortions as a probe of dark energy
(University of Western Cape, 2014)We begin by finding a system of differential equations for the background and linearly perturbed variables in the standard, ɅCDM model, using the Einstein Field Equations, and then solving these numerically. Later, we ... -
Regional groundwater monitoring in the Olifants-doom water management area
(University of Western Cape, 2006)The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the OlifantsDoom Water Management (WMA) area. Regional groundwater monitoring is ... -
Regional groundwater monitoring in the Olifants-Doorn water management area
(University of the Western Cape, 2006)The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the Olifants-Doorn Water Management (WMA) area. The general approach was to attempt ... -
Regional structure of the Central Kalahari sub-basin and the geometry and effect of the dolerite sills in the area
(University of the Western Cape, 2014)The potential for Coal Bed Methane (CBM) has been assessed in the Karoo-aged coal seams in Eastern Botswana. This region is underlain by the Central Kalahari sub-basin of the Karoo Sequence and hosts a major thermal coal ... -
Regulatory attributes of the carotenoid biosynthetic pathway in Arabidopsis Thaliana under abiotic stress
(University of the Western Cape, 2012)Carotenoids are tetraprenoid (C40) molecules synthesized in plants, fungi, bacteria and algae, via the carotenoid biosynthetic pathway (CBP). Some carotenoids are readily converted to vitamin A (VA) in humans, e.g. ... -
Rehabilitation as a method of understanding vegetation change in Paulshoek, Namaqualand
(University of the Western Cape, 2005)Heavy grazing of rangelands in the succulent karoo has placed the biodiversity of these areas at risk. In Paulshoek, overgrazing has resulted in the removal of much of the palatable vegetation from low lying areas. The ... -
The relationship between "fertilizaiton environment" and structure and physiology of selected Anuran Spermatozoa
(University of the Western Cape, 1993)The propagation of species and modes of fertilization of higher vertebrates are aspects which have been extensively researched. Studies on the spermatology of lower vertebrates have not received the same attention. Anurans ... -
