Human imprint on Earth is actually so profound leading global environmental changes that affects and modifies the functioning of ecosystems. Among the natural biomes, freshwater ecosystems are remarkable habitats that ...
Investigation of the involvement of mitochondrial DNA variants in cardiometabolic disease : the SABPA study
(North-West University (South Africa), Potchefstroom Campus, 2017)
Mitochondria are intricately involved in cell homeostatic and adaptive stress signalling pathways, and play a central role in cell differentiation, proliferation and death. Consequently, mitochondrial dysfunction has been ...
Landscape function in bush thickened and -controlled areas of the semi-arid savanna in the Molopo region, South Africa
(North-West University, 2017)
Bush thickening (bush encroachment) and the effects thereof on the environment has been a very well debated topic over the past few decades which led to the formation of two valid but rather opposite opinions. Pasture ...
The feasibility of alternative fuels to reduce air emissions from South African cement production
(North-West University, 2017)
The research aims to determine the feasibility of alternative fuel co-processing to reduce kiln stack emissions and focussed on the calculation of possible reductions in these emissions when substituting one tonne of ...

(North-West University, 2017)
The water quality of Wilge River sub-catchment in the upper Olifants water management area is under threat from a number of land-use activities. The aims of this study is to use existing environmental monitoring and ...
Re-assessment and optimisation of an organic acid extraction method for automation
(North-West University (South Africa), Potchefstroom Campus, 2017)
Sample preparation is a necessary prerequisite for GC/MS analysis of urinary
organic acids for clinical diagnosis of inborn errors of metabolism (IEM). The sample
clean-up step in the analytical process poses a challenge. ...
Air movement on and around tailings storage facilities on the Highveld of South Africa
(North-West University (South Africa), Potchefstroom Campus, 2017)
Dust from gold tailings storage facilities (TSFs) is problematic in certain areas of the South African Highveld. Many of these localities around TSFs are densely populated, which often result in tailings dust being a ...
Evaluation of grouping methods for solving one-mode blockmodeling problems

This dissertation sets out to describe how the social dynamics in mixed land-use developments can be used as an informative to plan sustainable social communities. The World Urbanisation Prospects of 2014 indicated that ...
Water leaching of inorganic species from coal ash and slag generated at typical Underground Coal Gasification (UCG) temperatures
(North-West University (South Africa), Potchefstroom Campus, 2017)
Underground coal gasification (UCG) is a better and more environmentally friendly way of gasifiying coal, using coal seams that are not economically viable to mine or coal seams that are deep underground. This technology ...
