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 ... -
The relationship between male genital tract infection, oxidative status in the ejaculate, and apoptotic markers in human spermatozoa
(2009)Aim: Leukocytes are the major source of reactive oxygen species (ROS) in the ejaculate and contribute to up to 30% of male infertility. ROS have been associated with markers of apoptosis such as sperm DNA damage, ... -
The relationship between sediment composition and infaunal polychaete communities along the southern coast of Namibia
(University of the Western Cape, 2005)This study examined the relationship between sediment structure and infaunal polychaete communities off the southern coast of Namibia from two separate sets of data, and a total of ninety-two samples. It also examined ... -
The relationship between structure and thermostability of a nitrile hydratase from Goebacillus pallidus RAPc8
(University of the Western Cape, 2008)Nitrile hydratases (NHases) are very important biocatalysts for the enzymatic conversion of nitriles to industrially important amides such as acrylamide and nicotinamide. An “ideal” NHase should fulfil several essential ... -
The relationship between the church and the reign of God in the reconstruction theology of JNK Mugambi: a critical analysis
(2013)Reconstruction theology is widely regarded as one of the most influential approaches to contemporary African Christian theology – alongside others such as inculturation theology, liberation theology, African women’s theology, ... -
The relative impact of an argumentation-based instructional intervention programme on grade 10 learners’ conceptions of lightning and thunder
(2012)The basic premise of this study was that when a learner is confronted with two contradictory explanations of the same phenomenon, there is cognitive dissonance in the learner as the learner tries to determine which of the ... -
A relativistic analysis of proton-induced knockout reactions from oxygen isotopes with direct and inverse kinematics.
(University of the Western Cape, 2020)In this study a complete set of exclusive (~p; 2p) polarization transfer observables of closed-shell oxygen isotopes are calculated using both direct and inverse kinematics using the relativistic plane wave impulse app ... -
Relativistic corrections to the power spectrum
(University of the Western Cape, 2015)The matter power spectrum is key to understanding the growth of large-scale structure in the Universe. Upcoming surveys of galaxies in the optical and HI will probe increasingly large scales, approaching and even exceeding ... -
The relevance of fog and dew precipitation to succulent plant hydrology in an arid South African ecosystem
(2009)Fog and dew interception and utilization by plant canopies remains one of the least considered aspects of vegetation studies at any scale yet the few studies that have been conducted point to their considerable influence ... -
Reliability of panoramic radiographs to determine the vertical position of the impacted third molar root tip from the inferior alveolar canal
(2013)Nowadays, the availability of radiographic modalities from conventional radiography to more advanced approaches such as medical computed tomography as well as cone beam computed tomography have been useful in providing ... -
Reliable numerical simulations of problems for pricing real estate derivatives
(University of the Western Cape, 2022)The globalisation of nancial systems has presented new challenges to investing in real estate assets. For example, any crisis occurring in one real estate market will have an adverse e ect on other markets regardless ... -
Religion, education and child immunization in Ethiopia
(University of the Western Cape, 2007)This study examines the relationship between immunization status of children and religion before and after controlling for other factors such as maternal education in Ethiopia, a country characterized by highest mortality ... -
Remote sensing and multispectral imaging of hydrological responses to land use/land cover and climate variability in contrasting agro-ecological systems in Mountainous catchment, Western Cape
(University of the Western Cape, 2022)Water is a fundamental resource and key in the provision of energy, food and health. However, water resources are currently under severe pressure as a consequence of climate change and variability, population growth and ... -
A Remote sensing change detection study in the arid Richtersveld region of South Africa
(University of the Western Cape, 2007)The Richtersveld falls within the succulent karoo and dester biomes. This studu made use of remote sensing technologies in order to investigate possible vegetation cover changes that have taken place over time, and which ... -
Remote sensing drought impacts on wetland vegetation productivity at the Soetendalsvlei in the Heuningnes Catchment, South Africa
(University of Western Cape, 2021)This work aimed at assessing the response of wetland vegetation productivity to the 2014-2017 climate-induced drought at the Soetendalsvlei wetland system in the Western Cape province of South Africa. To achieve this ... -
