A comparison between estimated renal function from point-of care derived cystatin c measurements and serum creatinine derived measurements
(University of the Western Cape, 2022)Serum Creatinine (SCr) is the most commonly used and cost effective biomarker used to quantify estimated glomerular filtration rate. However, creatinine is affected by anthropometric parameters such as muscle mass, age ... -
Comparison of actinobacterial diversity in Marion Island terrestrial habitats
(University of the Western Cape, 2008)The major aim of this study is to determine and compare the distribution of bacteria and actinobacteria in Marion Island terrestrial habitats. -
Comparison of flavonoid profile and respiratory smooth muscle relaxant effects of Artemisia afra versus Leonotis leonurus
(University of the Western Cape, 2015)Leonotis leonurus (L. leonurus) and Artemisia afra (A. afra) are two of the most commonly used medicinal plants in South Africa traditionally advocated for use in asthma. However, proper scientific studies to validate these ... -
A comparison of machine learning techniques for hand shape recognition
(University of the Western Cape, 2015)There are five fundamental parameters that characterize any sign language gesture. They are hand shape, orientation, motion and location, and facial expressions. The SASL group at the University of the Western Cape has ... -
Comparison of multi-gene integration strategies in CRISPR-based transformation of Saccharomyces cerevisiae
(University of Western Cape, 2021)Saccharomyces cerevisiae is an important host in industrial biotechnology. This yeast is the host of choice for the first and second-generation biofuels for ethanol production. Genome modification in S. cerevisiae has been ... -

Comparison of neutron fluence spectra measured with NE213 proton recoil spectrometer and NE230 deuteron recoil spectrometer
(University of the Western Cape, 2014)A (5 cm × 5 cm) cylindrical NE213 liquid organic scintillator and a (2.5 cm × 2.5 cm)cylindrical NE230 liquid organic scintillator were used as spectrometers. A series of measurements was made with both the NE213 and NE230 ... -
Comparison of plasmids from clinical Lactobacillus strains
(University of the Western Cape, 2018)The vaginal mucosa is dominated by Gram positive, rod shaped lactobacilli which serve as a natural barrier against infection. In both healthy and BV infected women Lactobacillus crispatus and Lactobacillus jensennii has ... -

A comparison of SAAS and chemical monitoring of the rivers of the Lesotho Highlands Water Project
(University of the Western Cape, 2004)The Lesotho Highlands Development Authority routinely uses the South African Scoring System version 4 (SASS4) in conjunction with water chemistry to monitor water quality of rivers in the Lesotho Highlands Water Project ... -
A comparison of some aspects of the masticatory apparatus of the cape mole-rat, Georychus capensis with that of the cape dune molerat, Bathyergus suillus
(2009)Some African mole-rats of the family Bathyergidea have dramatically different ecological niches which may cause selective anatomical adaptations. Bathyergus suillus lives in sandy soil and eats a wide range of food whereas ... -
Comparison of the physicochemical characteristics and flavonoid release profiles of Sutherlandia frutescens phytosomes versus liposomes
(University of the Western Cape, 2016)Sutherlandia frutescens is a traditional plant medicine widely used in South Africa. Traditionally, the leaves of S. frutescens are mainly used as a tea, but these traditional dosage forms have several disadvantages, ... -
Comparison of the sutherlandioside B levels in two commercially available Sutherlandia frutescence preparations and the effect of elevated temperature and humidity on these levels
(University of the Western Cape, 2009)Sutherlandia frutescens (tribe Galegeae, Fabaceae), is a popular medicinal plant traditionally used in South Africa. In 2000, a company called Phyto Nova (Pty) Ltd. initiated large-scale cultivation and contract manufacturing ... -
Comparison of the trough levels of two vancomycin formulations in a selected preterm infant population
(University of the Western Cape, 2014)The aim of this study was to compare the trough plasma levels of Aspen-Vancomycin® (AV); and Sandoz-Vancocin CP® (SV) in premature infants with suspected Methicillin Resistant Staphylococcus aureus (MRSA) infection. The ... -
Complexation and Bioavailability of Dissolved Mercury Evaluation by Hplc and a Novel Au-Hydrogel Analytical Sensor Protocol.
(University of the Western Cape, 2017)Anthropogenic sources as well as natural contributions (e.g. volcanic activity and evaporation from the oceans) have increased mercury levels in the environment. Mercury deposits mainly in sediments, and it finally ends ... -
The Complexity of Splay Trees and Skip Lists
(University of the Western Cape, 2008)Our main results are that splay trees are faster for sorted insertion, where AVL trees are faster for random insertion. For searching, skip lists are faster than single class top-down splay trees, but two-class and multi-class ... -
The Complexity of Splay Trees and Skip Lists
(University of the Western Cape, 2008)Binary search trees (BSTs) are important data structures which are widely used in various guises. Splay trees are a specific kind of binary search tree, one without explicit balancing. Skip lists use more space than BSTs ... -
Composite low temperate hydrogen storage material on the basis of iron-titanium alloy ; synthesis and structure
(University of the Western Cape, 2006)It is widely believed that hydrogen will within a few tens of years become the means of storing and transporting energy. The reason is the depletion of hydrocarbons and the relatively facile production of hydrogen from ... -
Composite poly(dimethoxyaniline) electrochemical nanobiosensor for glufosinate and glyphosate herbicides
(University of the Western Cape, 2008)In this thesis, I present a simple, sensitive and low cost electrochemical nanobiosensor for quantitative determination of the herbicides glufosinate, glyphosate and its metabolite aminomethylphosphonic acid (AMPA). Firstly, ...
