Biochemical analyses of deficiencies in the oxidative phosphorylation system in human muscle
(North-West University, 2007)
MitochondriaI disorders are caused by biochemical abnormalities of the mitochondrial respiratory chain (RC), a key component of oxidative phosphorilation (OXPHOS). The diagnosis of a RC deficiency can be invasive, expensive, ...
Modelling the water quality in dams within the Umgeni Water operational area with emphasis on algal relations
(North-West University, 2007)
Based on many years of water quality (including algal) and water treatment cost data, available at Umgeni Water, a study was undertaken to better understand the water quality relationships in man made lakes within the ...
A comparative study of non-parametric distribution function estimators
(North-West University, 2007)
The purpose of this study is to investigate a procedure for estimating the bandwidth in kernel
distribution function estimation based on the bootstrap. To investigate to performance of
the estimator) simulation studies ...

Improvement of sensitivity for foodstuff elemental analysis through thermal and/or EPI-thermal neutron activation analysis
(North-West University (South Africa), 2007)
Instrumental neutron activation analysis (INAA) for essential and toxic elements in foodstuffs
commonly consumed by South Africans as routinely applied at NECSA could not give adequate
sensitivity for a variety of elements ...
Micro-pixe study of arbuscular mycorrhiza influence on elemental uptake by Berkheya Coddii
(North-West University (South Africa), 2007)
Arbuscular mycorrhiza is a symbiotic association between fungi and plant roots. The
major advantage of the symbiosis is an enhanced supply of essential nutrients to
plants from the soil. At the same time mycorrhiza can ...
The use of stripped gas liquor (SGL) as process cooling water : analysis of the effects of operational conditions on microbial community dynamics, fouling, scaling and corrosion
(North-West University, 2007)
Sasol plants gasify more than 30 million tons per annum of coal via the Fischer-Tropsch process resulting in the production of synthesis gas and a condensate stream. After gravimetric separation of the tar products, the ...
Improving contaminated sewage sludge : an experiment based assessment of selected treatment options for the SASOL sewage works in Sasolburg (South Africa)
(North-West University, 2007)
Sasol Chemical Industries (SCI) located in Sasolburg, South Africa (SA), have since the early fifties produced fuels and waxes commercially, and recently diversified to produce a wider range of other chemicals. The Sasol ...
Microbial drinking water quality of selected rural, peri-urban and urban communities and schools in the North West Province, South Africa
(North-West University, 2007)
Safe drinking water is a basic human right. This study mainly focused on the physico-chemical and microbiological drinking water quality of selected rural, peri-urban and urban communities and schools in the ...
A comparison of selected enhanced (coated) and non-enhanced grass seed types for re-seeding of disturbed areas
(North-West University, 2007)
Restoration and rehabilitation activities are presently considered to be a major priority in environmental management, whether the activity implies the restoration of neglected cultivated pastures or degraded rangelands ...
