Modeling the effects of environmental and ecological processes on the transport, mortality, growth, and distribution of early stages of cape anchovy (engra ulis encrasicolus) in the Benguela system
(University of the Western Cape, 2003)
An individual based modeling approach was used to study environmental factors and processes influencing the early life history of anchovy in the southern Benguela region and on the Agulhas Bank. The intention was to then ...
Substituted nick el pyrazole and palladiumpyruzolyl complexes as catalyst precursors for ethylene polymeization
(University of the Western Cape, 2003)
This study concerns the synthesis of pyrazole and substituted pyrazole nickel
complexes of the type [(3,5-R,R',pz)2NiB rz ( Pz : pyrazole; R = R' = cHr (1), tBu
(a)l and of the type [(3,5-R,R'pz)aNiBrz R: H, R' : CHr ...
The synthesis of methoxy-2-hydroxy-1,4- naphthoquinones and their reaction with aliphatic aldehydes under basic conditions.
(University of the Western Cape, 2003)
Although literature reports on the synthesis of variously substituted 2-hydroxy-1 ,4-
naphthoquinones appeared to be reasonable; in our hands difficulty was experienced
in duplicating much of the work.
In order to address ...
Hydro geochemical characteristics of the basement aquifers in namaqualand
(University of the Western Cape, 2003)
At the onset of this research programme it became apparent that there is a dearth of
research studies focusing on the groundwater resources of the region. As a result, a
conceptual representation of the hydrogeological ...
Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
(University of the Western Cape, 2003)
Thermal analysis data of compounds A, C, F and I established that they were nonmesogenic
while E and G were found to be mesogenic. The lack of mesogenic behaviour
of A could be attributed to hydrogen bonding. The ...
Analyses of sequence divergence using completely sequenced genomes
(University of the Western Cape, 2003)
Using the complete genome, Saccharomyces cerevisiae, which duplicated after its
speciation fuom Kluyveromyces lactics, a dataset of 119 putative S. cerevisiae - K.
lactis ortholog-pairs was constructed. S. cerevisiae ...
Pyrazolyl palladium complexes with heterocyclic carbonyl linkers as catalyst precursors for ethylene and phenylacetylene polymerization.
(University of the Western Cape, 2003)
The pyrazolyl ligands 2,6-bis(3,5-r2p*azolylcarbonyl)pyridine {r : 'bu (l1), me (l2)),2,6-bis(3-methylpyrazolylcarbonyl)pyridine(l3)'2'6- bis(pyrazolylcarbonyl)pyridine (l4) and 2,5-bis(3,5-rzpyrazolylcarbonyl)thiophene { ...
The identification of potential groundwater zones in the Kamiesberg region, Northern Cape province, South Africa
(University of the Western Cape, 2003)
The aim of the study is to apply remote sensing techniques to identify potential groundwater resources for the Kamiesberg region. This region, with vast water shortages relies solely on groundwater and is characterized by ...
Identification and characterisation of the role of endozepine in apoptosis induced by ceramide
(University of the Western Cape, 2003)
Apoptosis is a form of programmed cell death and is required for the normal development, tissue homeostasis and survival of organisms. The identification of mutations that can lead to alterations in cell death not only ...
The experimental cultivation and alginate properties of South African kelps
(University of the Western Cape, 2003)
Alginates are used in various industries and the quality of alginates used must be controlled. Alginates used for medical purposes must be of a very high quality. The cost of obtaining high-quality alginate is high and ...
