Evaluation of the suitabil[i]ty of Fischer-Tropsch gas-to-liquid (GTL) Primary Column Bottoms as process cooling water : analysis of microbial community dynamics, fouling, scaling and corrosion
(North-West University, 2007)
Water in South Africa is becoming limiting due to economic growth, social
development and the country's water demand that exceed its water availability. Water
conservation in the industry can be accomplished by the reuse ...
Metathesis and transalkylation in tandem catalysis
(North-West University, 2007)
Longer chain terminal alkenes, which are in high demand in industry, can be obtained from widely available shorter chain terminal alkenes in a tandem catalysis reaction. Tandem catalysis involves me combination of multiple ...
Evaluation of selected soil properties in semi-arid communal rangelands in the Western Bophirima district, South Africa
(North-West University, 2007)
Concerns were raised over the past decades, on the degradation condition of arid and semi-arid range lands in South Africa, mainly in areas under communal land management. Baseline information on soil quality is essential ...
Assessment of epigeal arthropods along an urbanization gradient in the municipal area of Potchefstroom, North-West Province, South Africa
(North-West University, 2007)
Human activities have dramatically altered the functioning of ecosystems through the ages. Urbanization illustrates the effect of anthropogenic activity by the transformation of natural areas to ecologically disturbed ...
Modelling of the heliosphere and cosmic ray transport
(North-West University, 2007)
A two dimensional hydrodynamic model describing the solar wind interaction with the local interstellar medium, which surrounds the solar system, is used to study the heliosphere both as a steady-state- and dynamic structure. ...
Modellering en sintese van alisikliese fosfienverbindings as ligande
(North-West University, 2007)
In this study alicyclic phosphine compounds were identified from the literature that has the potential to be used as new ligands for the Grubbs-type catalyst system. Molecular modelling was used to investigate the productive ...
The evaluation of the establishment and growth of indigenous trees to restore deforested riparian areas in the Mapungubwe National Park, South Africa
(North-West University, 2007)
The deforestation of riparian areas is a major concern in southern Africa. These areas are characterized as fragile ecosystems which contribute largely to the regional and global biodiversity of the world. It is therefore ...
Simulation modelling and analysis of a satellite campus's registration model
(North-West University, 2007)
The registration model is a very important part of any tertiary education institution's value chain, as this is the first contact that many students have with the institution. Therefore it is of extreme importance that ...
Recovery of gold from spent matrices using supercritical carbon dioxide
(North-West University, 2007)
The feasibility of recovering gold preloaded onto activated carbon by supercritical
carbon dioxide (sc-CO2) was investigated in view of the actuality of a more environmentally friendly process for the retrieval of gold ...
Experimental and theoretical investigation of new Grubbs-type catalysts for the metathesis of alkenes
(North-West University, 2007)
Ondanks die hoe selektiwiteit van die eentegenerasre Grubbs-prekatallsator (Grl) gedurende die metatese ban terminale alkene, het dit 'n kort leeftyd by verhwgde temperature. Die ontwikkeling van die tweedegenerasie ...
