Functional characterisation of a novel ferulic acid esterase from malawian hot spring metagenome
(2011)There has been a decline in the global fossil fuel reserves, due to an increasing demand for petroleum. Biofuels can be used as an alternative source of energy whereby biomass is converted to liquid fuels such as bioethanol. ... -
Functional characterisation of a thermophilic cellulase from a Malawian metagenomic library
(2013)Biofuels are currently recognised as the most viable source of energy to replace depleting fossil fuel reserves, with bioethanol the most popular alternative alcohol fuel. Producing bioethanol from agricultural waste ... -
Functional genomic characterization of fruit quality traits in apple (Malus x domestica Borkh)
(University of the Western Cape, 2009)The domesticated apple (Malus x domestica Borkh), belonging to the Malusgenus of the Rosaceae family, is one of the edible pomaceous fruits. Since it is one of the important commercial fruit crops worldwide, the quality ... -
Functional importance of snakes in a strandveld ecosystem
(University of the Western Cape, 2018)Gaps in our knowledge of the functional roles of snakes within ecosystems limit our ability to predict the potentially cascading effects their removal from an ecosystem might create. Extirpation of snake species could ... -
Functionalisation of electrospun nanofibre for lanthanide ion adsorption from aqueous solution
(University of the Western Cape, 2018)Rare earth elements (REEs) have widespread use and importance for industrial applications due to their metallurgical, optical and electronic properties. Several typical hydrometallurgical techniques such as adsorption, ... -
Functionalisation of polymer nanofibres and track-etched membrane removal of organic and and inorganic pollutants from water
(University of the Western Cape, 2017)Organic and inorganic pollutants are two broad classes of pollutants in the environment with their main sources from waste waters that are indiscriminately dumped from chemical related industries. Among the organic ... -
Functionality and comparative advantages among the provinces of South Africa: A location quotient analysis of employment distribution.
(University of Western Cape, 2019)The purpose of the study is to examine the functions of provinces in South Africa and their respective comparative advantages from 2013 to 2017, in terms of employment absorption. It is predicted or assumed that there are ... -
Galaxy Clustering as a Probe for Galaxy Evolution in Simulations
(University of the Western Cape, 2017)Studying clustering on small scales (<10Mpc) over a large span of red- shifts allows us to connect galaxies to underlying cosmic large-scale structure, and thereby provide constraints on the physical processes that drive ... -
Galaxy evolution and cosmology studies using luminous red galaxies
(University of the Western Cape, 2014)There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs). Assuming that stars in LRGs form at the same time, age-dating of two populations of LRGs ... -
Galaxy Evolution and Cosmology using Supercomputer Simulations by Daniel Cunnama
(University of the Western Cape, 2013)Numerical simulations play a crucial role in testing current cosmological models of the formation and evolution of the cosmic structure observed in the modern Universe. Simulations of the collapse of both baryonic and ... -
Gallic acid modulates salt stress tolerance in soybean plants by regulating antioxidant capacity
(University of the Western Cape, 2017)Soybean [Glycine max L (mer)] is one of the top commodity crops in the world including South Africa (de Beer and Prinsloo, 2013). These small yet important podded legumes are a great source of protein and are used in many forms. -
Gaming and computer science: Bridging the gender-gap
(University of the Western Cape, 2019)According to the literature, women are still unrepresented in the field of information technology. Although many women study computer science at first year level, the dropout rate for women—before they graduate—is high, ... -
Gamma spectroscopy and lifetime measurements in the doubly-odd 194tl nucleus, revealing possible chiral symmetry breaking
(University of the Western Cape, 2013)In the first experiment high spin states in 194Tl, excited through the 181Ta (18O, 5n) heavyion fusion evaporation reaction were studied using the AFRODITE array at iThemba LABS. The γ-γ coincidences, RAD ratios and linear ... -
Gamma spectroscopy of the doubly– ODD 194Tl Nucleus
(University of the Western Cape, 2006)The odd – odd Tl nuclei with A ≥ 190 have moderate oblate nuclear deformation and show rotational bands built on different quasiparticle excitations. Several phenomena, not yet fully understood, were observed in these ... -
Garlic and African olive used as traditional Herbs for hypertension in the Western Cape
(University of the Western Cape, 2012)Hypertension is a common chronic health problem worldwide due to contributing factors such as obesity, physical inactivity, unhealthy diet and changes in lifestyle. The standard of care for hypertension in South Africa is ... -
Gas diffusion electrodes for high temperature polymer electrolyte membrane fuel cells membrane electrode assemblies
(University of the Western Cape, 2014)The need for simplified polymer electrolyte membrane fuel cell (PEMFCs) systems, which do not require extensive fuel processing, has led to increased study in the field of high temperature polymer electrolyte membrane fuel ... -
Gas sensing properties of Ceo2 nanostructures
(University of the Western Cape, 2020)The industrial safety requirements and environmental pollution have created a high demand to develop gas sensors to monitor combustible and toxic gases. As per specifications of World Health Organization (WHO) and Occupational ... -
Gender and perceptions of science and science education: a case study in Mitchells Plain
(2012)The literature on the manner in which gender influences the participation and performance of girls and boys in science and science education indicates that the disparity between the genders, in favour of boys, persists. ... -
Gene Discovery in Antarctic Dry Valley Soils
(University of the Western Cape, 2008)The metagenomic approach to gene discovery circumvents conventional gene and gene product acquisition by exploiting the uncultured majority of microorganisms in the environment. It was demonstrated in this study that ... -
Gene expression of xenobiotic metabolising enzymes in rat liver and kidney: differential effects of rooibos and honeybush herbal teas
(2011)Laboratory studies, epidemiological investigations and human clinical trials indicate that flavonoids have important effects on cancer chemoprevention and therapy. Flavonoids may interfere in several steps that lead to ...
