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 ... -
