Bionomics of vector-borne diseases in sites adjacent to lakes Victoria and Baringo in Kenya
(University of the Western Cape, 2016)Bionomics of vector-borne pathogens (VBPs) is a complex phenomenon that involves understanding the ecology of arthropod borne pathogens and vertebrate hosts potentially involved in their transmission cycles. Investigations ... -
Bioprospecting for bioactive polysaccharides from marine algae endemic to South Africa
(University of the Western Cape, 2016)Fucoidan is a marine-derived sulphated polysaccharide with bioactive properties ideal for the food, chemical and pharmaceutical industries. The polysaccharide consists largely of L-fucose, has a highly heterogeneous structure ... -
Biosimilar’s Growth in Pharmerging Markets: An Analysis of the Regulatory Environments
(University of the Western Cape, 2020)The introduction of biosimilars to health care markets across the globe has had some success in increasing competition and improving the cost of healthcare. While savings are important for driving the biosimilar uptake, ... -
Biosurfactant screening through metagenomic and culture-based approaches
(University of the Western Cape, 2022)The biosurfactant market is still predominantly represented by the three main products: surfactin, sophorolipids, and rhamnolipids, mainly as a result of the high cost and low yield associated with biosurfactant production. ... -
The Birch and Swinnerton-Dyer Conjecture for elliptic curves.
(University of the Western Cape, 2014)The aim of this dissertation is to provide an exposition of the Birch and Swinnerton-Dyer Conjecture, considered by many to be one of the most important unsolved problems in modern Mathematics. A review of topics in Algebraic ... -
Block Toeplitz operators with rational symbols and discrete singular systems
(University of the Western Cape, 2001)This thesis concerns block Toeplitz operators (equations). Consider the block Toeplitz operator T = [<I> k-j ]k,j=O' where the <I>k are complex m x m matrices such that 00 (0.1) v=-oo The norm in (0.1) is the usual ... -
Blood cell histology of Homopus areolatus: effects of season and cohort
(University of the Western Cape, 2015)Homopus areolatus is an endemic terrestrial tortoise that resides in a Mediterranean type of climate, which is characterised by winter rainfall and mild winter temperatures. Within ectotherms, such as H. areolatus, ... -
Boron-doped Diamond Sensors for the Determination of Organic Compounds in Aqueous Media
(University of the Western Cape, 2010)In electrochemical oxidation treatment of wastewater, the electrode material is an important parameter in optimizing oxidative electrochemical processes, since the mechanism and products of several anodic reactions are ... -
Boundedness and pseudocompactness in pointfree topology
(University of Western Cape, 2019)This dissertation is a presentation to generalize boundedness and pseudocompactness in pointfree topology. We rst obtain and introduce a boundedness notion for elements of a frame. This is then further inspiration to ... -
Brine shrimp lethality test and acetylcholine esterase inhibition studies on selected South African medicinal plants
(University of the Western Cape, 2012)Research into traditional medicines is often conducted in a multidisciplinary approach as motivated by a desire to understand them in as complete a manner as possible,realizing their chemistry, biology and pharmacology. ... -
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)The current study investigated application of natural adsorbents in brine treatment. Brines are hypersaline waters generated in power stations and mining industries rich in Mg2+, K+, Ca2+, Na+, SO4 2- , Cl- and traces of ... -
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ... -
Browser-based and mobile video communication alternatives for Deaf people
(University of the Western Cape, 2011)This thesis offers some prototypes to provide browser-based and mobile video communication services for Deaf people and evaluates these prototypes. The aim of this research is to identify an acceptable video communication ... -
Burial history and source rocks characteristics of the montney formation, Alberta basin, Canada
(University of the Western Cape, 2016)More than 300 samples from the Montney Formations in the Alberta basin, offshore, Canada have been analysed with locations in various parts of the Alberta basin. These samples were mainly analyzed from two wells (well M28 ... -
The C-economy, nutritional benefits and symbiotic performance of dual inoculated Phaseolus vulgaris (L.) plants, under variable nutrient conditions
(University of the Western Cape, 2010)The tripartite symbiosis between Phaseolus vulgaris, arbuscular-mycorrhiza and the nodule bacteria, Rhizobia have been the focus of many studies ranging over a number of decades, however these studies have failed to answer ... -
