Evaluation of the monitoring system for volatile organic compound (VOC) emissions at NATREF, South Africa
(North-West University, 2004)
An evaluation of the VOC (Volatile Organic Compound) emissions monitoring system of Natref (National Refiners of South Africa) was conducted to determine the
effectiveness of the system. Natref monitors fugitive plant ...
Functional properties of metallothionein expression in mitochondrial NADH : ubiquinone oxidoreductase deficiency
(North-West University, 2004)
NADH:ubiquinone oxidoreductase (complex I) deficiency is one of the most frequently encountered causes of mitochondrial respiratory chain disorders. One of the major consequences of such a complex I deficiency is the ...
MtDNA landscape in South African paediatric patients clinically diagnosed with suspected mitochondrial disorders
(North-West University, 2004)
The relevance of haplogroups in mitochondrial disease was investigated in this study.
Twenty-seven paediatric patients with clinically suspected mitochondrial disorders from
diverse ethnic origins were investigated via ...
Perturbation of critical metabolic processes associated with 3-hydroxynorvaline induced teratogenesis
(North-West University, 2004)
Neural tube defects (NTD) are a group of folate-responsive congenital defects that
occur relatively frequently in humans. NTD display a multi-factorial aetiology, resulting from a complex interplay of genetic and environmental ...
Urban regeneration in a South African context
(North-West University, 2004)
As a result of the transition from a modern to post-modern society, and the realization that the earth's resources are no longer infinite, a diversity of uses needs to be created in order to balance out the increasing ...
An ecological study into the possible reclamation value of reedbeds in a coal mine wetland system in Kwazulu-Natal
(North-West University, 2004)
The single biggest environmental problem facing the coalmine industry today is the high acid
concentration in mine runoff water. After pollution prevention and effluent reuse, reclamation is the
most important component ...
The hydrological impact of the rewatering of the Gemsbokfontein dolomitic compartment on the Wonderfonteinspruit
(North-West University, 2004)
Water is an essential resource for any life on earth but water is also the most poorly
managed of all resources. Many countries are facing a water crisis and South Africa
is no exception. The dolomitic groundwater ...
A new distribution function estimator based on a nonparametric transformation of the data with applications
(North-West University, 2004)
The purpose of this study is to investigate the properties of a bias reduction kernel estimator of a
distribution function and to compare it with existing estimation techniques in the bootstrap. The
procedure which is ...
Effects of land-use on avian demography in the Kalahari area of the North-West Province, South Africa
(North-West University, 2004)
Desertification, whether due to anthropogenic pressures, climate change or other factors, has become a global concern. The far-reaching effects of desertification have prompted the formation of the United Nations Convention ...
Modelling of galactic and jovian electrons in the heliosphere
(North-West University, 2004)
A three-dimensional (3D) steady-state electron modulation model based on Parker (1965) transport equation is applied to study the modelling of – 7 MeV galactic and Jovian electrons in the inner
heliosphere. The latter ...
