Invariant solutions and conservation laws for soil water redistribution and extraction flow models
(2003)In this dissertation we use Lie symmetry analysis to obtain invariant solutions for certain soil water equations. These solutions are invariant under two-parameter symmetry groups obtained by the group classification of ... -
Investigate the possible reduction of mine water ingress by introducing tree plantations
(North-West University (South Africa), Potchefstroom Campus, 2017)Continuous influx of groundwater into underground mine workings requires significant financial investment in terms of high pumping costs associated with the pumping of large volumes of water ingress, that could eventually ... -
Investigating critical success factors in agile systems development projects
(North-West University, 2012)This study investigates the critical success factors involved in agile systems development projects. Various systems development methodologies and project management methodologies are presented with their underlying ... -
Investigating factors influencing UAS task automation in dynamic environments
(North-West University (South Africa), 2020)UAS (Unmanned Aerial System) technology and capabilities have greatly improved which means that there are increased application possibilities and various industries in diverse fields are starting to show interest in UAS ... -
Investigating gene mutations in a South African paediatric cohort diagnosed with mitochondrial disease
(North-West University (South Africa). Potchefstroom Campus, 2019)Mitochondrial diseases (MD) are a clinically heterogenous group of genetic disorders that affect the neuromuscular system, the central nervous system (collectively known as encephalomyopathies), and other high-energy ... -
Investigating household behaviour towards recycling: a case study in the town of Vryheid- Bhekuzulu
(North-West University (South Africa), 2019)This study aimed to investigate household awareness and willingness towards recycling. The study was limited to Vryheid and Bhekuzulu a small town situated in the Northern parts of Kwazulu-Natal. The empirical study ... -
Investigating morphological changes in fish tissue, due to the presence of persistent organic pollutants and metals
(North-West University, 2012)Levels of selected metals and persistent organic pollutants (POPs) were investigated in sediment and fillet tissue of the sharptooth catfish (Clarias gariepinus), from sites along the Orange-Vaal River system, South Africa. ... -
Investigating neutrino production in Swift J1644+57
(North-West University (South Africa), 2020)The recent detection of astrophysical very-high-energy neutrinos by IceCube has spurred an intensive search for their sources. As possible sources of VHE neutrinos, tidal disruption events (TDEs) have been suggested. Here ... -
Investigating perceptions of stakeholders' positions, activities and specialisations at a serious game interest area (NWU, Vaal)
(North-West University (South Africa), 2020)The following study profiles the stakeholders in the context of serious game (SG) design and development. This interpretivist research is done to contribute towards a contemporary, integrated, stakeholder-centred framework ... -
Investigating reactive sputtered IrxNiyOz electrocatalysts for the oxygen evolution reaction
(North-West University (South Africa)North-West University, 2020)Alkaline water electrolysis (AWE) is a promising, simple and environmentally friendly technology, when coupled with renewable energy sources (e.g. wind and solar), to produce high purity hydrogen gas for clean energy ... -
Investigating soil algae and cyanoprokaryotes on gold tailings material in South Africa
(2014)Gold mine tailings material facilities are characterized by sparse vegetation and an abundance of dust. Mine tailings facilities are examples of extreme geotechnical and geochemical conditions which make it almost ... -
Investigating solid waste management in unserviced rural areas : a case study of Matobole Village, Limpopo Province
(North-West University (South Africa), 2023)Municipalities are mandated by the Constitution of the Republic of South Africa (RSA) to provide waste management services; however, most South African municipalities are struggling to provide these services due to a lack ... -
Investigating some heuristic solutions for the two-dimensional cutting stock problem
(North-West University, 2010)In this study, the two-dimensional cutting stock problem (2DCSP) is considered. This is a problem that occurs in the cutting of a number of smaller rectangular pieces or items from a set of large stock rectangles. It is ... -
Investigating South African Environmental Practitioners’ perceptions on the integration of specialist studies in EIA reports
(North-West University, 2016)Environmental Impact Assessment (EIA) is an important tool used globally to manage the impact of human activities on the environment, by identifying, predicting, evaluating and introducing mitigation measures for sustainable ... -
Investigating sputtered thin film Pt-containing electrocatalysts for SO2(aq) electro-oxidation
(North-West University (South Africa) , Potchefstroom Campus, 2016)Environmental concerns, social, economic and political pressure, and new technologies are the main factors driving change in energy systems around the globe. Human life and development are inevitably dependent on energy ... -
Investigating the adaptive mitochondrial shuttles and metabolic reprogramming of transporters in complex I (Ndufs4) knockout mice
