Solid phase micro extraction: an alternative technique for the determination of volatile orgnanic compounds in groundwater
(University of the Western Cape, 2004)
Standard methods for sample preparation use toxic organic solvents and can be replaced by utilizing a new sample preparation and concentration technique. One such technique, compatible with capillary gas chromatography was ...
Pyramlyl palladium(Il) complexes as phenylacetylene oligomerization and polymerization catalysts'
(University of the Western Cape, 2004)
PyrazoM compounds have been extensively used to prepare metal complexes, but it
is only recently that they have been investigated as catalysts for the polymerization of
unsaturated hydrocarbons. In catalyzn11g the ...
Specias delimitation and assessment of genetic variability in Carpobrotus (Alzoaceae): evidence from amplified fragment length polymorphisms
(University of the Western Cape, 2004)
Species of Carpobrotus (Aizoaceae: Ruschioideae) are widely spread throughout South Africa and are commonly used for their medicinal properties. The genus consists of 13 species of which seven occur in South Africa, five ...
Thermal stability and defect structure of hot-wire deposited amorphous silicon
(UWC, 2004)
Hydrogenated amorphous silicon (a-Si:H) thin films are presently used in several large-area thin-film applications. However, one major concern of a-Si:H is the fact that the stability of the material degrades when it is ...
Isolation and identification of PNP-A homologues from Xerophyta viscosa Baker
(University of the Western Cape, 2004)
Maintenance of growth, development and normal physiological processes remains crucial
for the survival of plants. Plant hormones are described as integrators of external signal
and internal developmental process in plants. ...
Salt tolerance and modification of wheat salt resistance by plant hormones
(University of the Western Cape, 2004)
The history of salt tolerance and the factors effecting salt resistance of plants were literature surveyed, and it was concluded that ion
concentration, salt accumulation, compatible solutes and the genetic traits play a ...
An investigation of the plants used medicinally In self-care in the Bredasdorp / Elim region
(University of the Western Cape, 2004)
Much of the traditional medicinal plant knowledge is to a large extent known by the
older generations. This knowledge is at risk of disappearing due to not being passed
down to younger members of the respective families ...
Computing Mislin genera of certain groups with non-abelian torsion radicals
(University of the Western Cape, 2004)
In this mini-thesis we present some generalities of non-cancellation and localization
and we compute non-cancellation groups. We consider groups belonging to the class
X0 of all finitely generated groups that have finite ...
A decision-making framework for groundwater management in arid zones (with a case study in Namaqualand).
(University of the Western Cape, 2004)
The main aim of the work on which this thesis is based was to develop a framework for sustainable management of groundwater resources in arid zones with emphasis on Namaqualand in the north western region of South Africa. ...
An investigation into the methodologies of value-at -risk and a simulation process of a portfolio of financial instruments.
(University of the Western Cape, 2004)
Financial companies such as investment and commercial banks as well as insurance companies, mutual and pension funds hold assets in the form of financial instruments in portfolios. Nowadays, financial instruments have ...
