Knowledge, perceptions and practices of risk-based monitoring among clinical practitioners in the United States
(University of the Western Cape, 2018)This study investigated the current knowledge, perceptions, and practices of Risk-Based Monitoring (RBM) using written and verbal responses to an ethics review board approved questionnaire. Responses were collected from ... -
Knowledge-based integration of Zimbabwean traditional medicines into the National Healthcare System: A case study of prostate cancer
(University of the Western Cape, 2017)This study sought to identify the bottlenecks in the promotion of Zimbabwean Traditional Medicines (ZTMs) towards improving the national healthcare delivery system. The indigenous medicines lost value and recognition to ... -
A knowledgebase of stress reponsive gene regulatory elements in arabidopsis Thaliana
(University of the Western Cape, 2011)Stress responsive genes play a key role in shaping the manner in which plants process and respond to environmental stress. Their gene products are linked to DNA transcription and its consequent translation into a response ... -
L-Cysteine-Capped Indium Telluriselenide Quantum Dot Aptasensor for Interferon-Gamma TB Biomarker
(University of the Western Cape, 2018)Tuberculosis (TB) is one of the major infectious diseases that affect the health of people all over the world. South Africa is one of the countries that account for most of the TB cases; it is the leading cause of death ... -
A lab based experimental study of a bioretention system to remove selected pharmaceuticals in stormwater
(University of the Western Cape, 2023)The use of treated stormwater as an alternative source of water supply in urban areas is receiving global recognition. This approach is being supported as an innovative initiative that improves urban water security and ... -
Labour force participation among African female migrants in South Africa: the case of Gauteng province
(University of the Western Cape, 2023)The African female migration theme has several dynamic components and characteristics that have not been fully explored. In the South African context, the influence of the labour force participation among African female ... -
Laccases from actinomycetes for lignocellulose degradation
(University of the Western Cape, 2012)Lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. Actinomycetes are known to produce laecases ... -

(University of the Western Cape, 2012)The purpose of this study shows that lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. ... -
Land use practices and their impact on the water quality of the Upper Kuils River (Western Cape Province, South Africa)
(University of Western Cape, 2014)The water quality in many Cape Town Rivers and streams is a major challenge. Kuils River is subject to multiple land use impacts from upstream to downstream because of rapid urbanization in its catchment area. The main ... -
A large-scale clustering analysis of radio galaxies
(University of the Western Cape, 2019)The distribution of the visible structure in the Universe is in part dependent on the in uence of the dark matter structure. Measurements of large-scale structure can therefore be related to the dark matter distribution ... -
Laser drilling of metals and glass using zero-order bessel beams
(University of the Western Cape, 2013)This dissertation consists of two main sections. The first section focuses on generating zero order Bessel beams using axicons. An axicon with an opening angle y = 5⁰ was illuminated with a Gaussian beam of width ω₀ = 1.67 ... -
Latent and thermal energy storage enhancement of silver nanowires-nitrate molten salt for concentrated solar power
(University of Western Cape, 2020)Phase change material (PCM) through latent heat of molten salt, is a convincing way for thermal energy storage in CSP applications due to its high volume density. Molten salt, with (60% NaNO3 and 40% KNO3) has been used ... -
Left versus right canonical wiener-hopf factorization for rational matrix functions: an alternative version
(University of the Western Cape, 1995)It is an established fact that both canonical and non-canonical Wiener-hopf factorizations of matrix functions play an important role in various aspects of mathematical analysis and its applications. Indeed, for instance, ... -
Lichen thermal sensitivities, moisture interception and elemental accumulation in an arid South African ecosystem
(University of the Western Cape, 2010)Elevated temperatures accompanying climate warming are expected to have adverse effects on sensitive lichen species. This premise was examined by measuring the sensitivity of different lichen species to elevated temperatures ... -
Lifetime measurements of excited nuclei through modern nuclear spectroscopy
(University of Western Cape, 2021)The progressive development of scintillator detectors has made it possible to perform direct electronic lifetime determination up to a few hundred nanoseconds. The 2" by 2" LaBr3:Ce detectors provide a combination of ... -

Linear polarization and lifetime measurement in ¹⁹⁴TL
(University of the Western Cape, 2006)High-spin states in¹⁹⁴TL were populated using the 181Ta1t8O, 5n) reaction at the beam energies of 91 and 93 MeV during two weekends of beam time. The 1^Tcoincidence data associated with this reaction were measured employing ... -
Linking biology and sustainable livelihoods to the proposed establishment of community -based Eucheumoid farming in southern Kenya
(University of the Western Cape, 2005)Growth rates of three commercial eucheumoids: brown Eucheuma denticulatum and green and brown Kappaphycus alvarezii were studied at three sites (Gazi Bay, Kibuyuni and Mkwiro) in southern Kenya. The study was conducted ...
