Using internet-enabled remote instrumentation for research and training in physics: evaluation of different diffusion barriers for silver metallization
(2007)
The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ...
Development and implementation of ontology-based systems for mammalian gene expression profiling
(2009)
The use of ontologies in the mapping of gene expression events provides an
effective and comparable method to determine the expression profile of an entire
genome across a large collection of experiments derived from ...
A comparison of some aspects of the masticatory apparatus of the cape mole-rat, Georychus capensis with that of the cape dune molerat, Bathyergus suillus
(2009)
Some African mole-rats of the family Bathyergidea have dramatically different
ecological niches which may cause selective anatomical adaptations. Bathyergus
suillus lives in sandy soil and eats a wide range of food whereas ...
Spectroelectrochemical determination of the antioxidant properties of carpobrotus mellei and carpobrotus quadrifidus natural products
(2009)
South African Carpobrotus species have been found to contain hydrolysable tannins,various flavonoids e.g. rutin and hyperoside, phytosterols and aromatic acids which have a diverse range of pharmacological properties ...
Affective gesture fast-track feedback instant messaging (AGFIM)
(University of Western Cape, 2005)
Text communication is often perceived as lacking some components of communication that are essential in sustaining interaction or conversation. This interaction incoherency tends to make text communication plastic. It is ...
Differentials in school attendance in South Africa: a household situational analysis across the provinces
(2009)
The thesis examines the patterns of school attendance across the nine Provinces of
South Africa. With reference to individuals of eligible age, school attendance is
conceived of three statuses: effective attendance (those ...
The ecology of the world's smallest tortoise, homopus signatus signatus: effects of rainfall
(2008)
Tortoises appear to be successful in arid ecosystems, where they depend on primary production for their predominantly herbivorous diets. The low primary production of arid regions is exacerbated by priodic droughts, so ...
Empirical and model derived respiration responses to climate in different soils of an arid South African ecosystem
(2009)
This study examined the magnitude of soil CO2 efflux in an arid South African ecosystem, the flux responses as well as those of key limiting nutrients to soil temperature increases and moisture reductions consistent with ...
Phylogeography and speciation in the genus arthroleptella
(2009)
Moss frogs are restricted to permanently moist terrestrial habitats in the south-western Cape Fold Mountains. There is a very close association between Arthroleptella distribution and Table Mountain Sandstone. Suitable ...
The relevance of fog and dew precipitation to succulent plant hydrology in an arid South African ecosystem
(2009)
Fog and dew interception and utilization by plant canopies remains one of the least
considered aspects of vegetation studies at any scale yet the few studies that have been conducted point to their considerable influence ...
