Oxidative fixation of dinitrogen by photocatalysis
(University of Western Cape, 2000)
The heterogeneous photocatalytic oxidation of dinitrogen to nitrate, NO3 and/or nitrite, no2 using peroxy species of titanium (IV) in aqueous suspensions has been investigated. The photocatalysts used were titanium peroxide ...
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
(University of the Western Cape, 2000)
Promoter detection, especially in prokaryotes, has always been an uphill task and may remain so, because of the many varieties of sigma factors employed by various organisms in transcription. The situation is made more ...
Synergistic use of promoter prediction algorithms: A choice for small training dataset?
(University of the Western Cape, 2000)
This chapter outlines basic gene structure and how gene structure is related to promoter structure in both prokaryotes and eukaryotes and their transcription machinery. An in-depth discussion is given on variations types ...
New algorithms for EST clustering
(University of the Western Cape, 2000)
Summary: Expressed sequence tag database is a rich and fast growing source of data for gene expression analysis and drug discovery. Clustering of raw EST data is a necessary step
for further analysis and one of the most ...
Synthesis, characterisation and reactions of ferrocene anchored bis(phosphino) palladium (II) and platinum (II) aryldichalcogenide complexes
(University of the Western Cape, 2000)
Reactions of M(dppf)Cl2 (M : Pd, Pt) and Pd(dippf)Cl2 with equimolar amounts of the aryldichalcogen reagents, 1,2-benzenedithiol (1,2-(HS)C6H4(SH) (a)), 3,4-toluenedithiol ((HS)C6H3Me(SH)) (b), 3,6-dichloro 1,2-benzenedithiol ...
Identification and partial characterisation of a putative novel plant stress response gene from Arabidopsis thaliana.
(University of the Western Cape, 2000)
Exposure of plants to stress results in the expression of plant genes whose products play a role in defence responses against the stress. Stress stimuli to which plants may be exposed are wounding, drought, salinity, ...
The determination of excitation functions for natRb+p up to 100 MeV with an emphasis on the production of 82Sr
(UWC, 2000)
The radioisotope strontiuur-S2 (T172= 25.55 days) decays to short-lived t"Rb 1T,, = 76 seconds) by l00o/o electron caphue @C). The short-lived t'*Rb decays by g5.SYopositron-ernissiou p* and 4.5%oEC to stable'2Kr. Rubidiurn-82g ...
The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)
The aim of this study was to determine the effect of maternal nicotine exposure on
the status of the rat tracheal development as well as the rat lung of 7 to 42 day old
offspring. Wistar dams were injected subcutaneously, ...
Exploration of the games of Malepa and Morabaraba in South African secondary school mathematics education
(University of the Western Cape, 2000)
This study is based on the Exploration of the Games of Malepa and Morabaraba in South African Secondary School Mathematics Education . It explores culturally specific games through a qualitative research methodology that ...
The antioxidant properties of melatonin during chemical hypoxia and reoxygenation injury in rat ventricular myocytes
(University of the Western Cape, 2000)
It is well known that ischaemia chemical hypoxia followed by reperfusion is not always accompanied by recovery of myocardial function and often produces further cell damage (Hearse et al., 1973). This phenomenon commonly ...
