Radiation dose and radionuclide inventory characterization following a hypothetical nuclear criticality accident at a uranium processing facility
(North-West University (South Africa), 2021)This study focused on a hypothetical nuclear criticality excursion in a Plutonium Uranium Reduction EXtraction (PUREX) processing facility for the recovery of non-irradiated enriched uranium, which are present in scrap ... -
A rapid method of biological dosimetry to assist in the event of a nuclear emergency
(North-West University (South Africa) , Potchefstroom Campus, 2013)There are concerns that a combination of human and mechanical errors at a nuclear facility could result in plant failure and lead to a significant level of harm to people and the environment. During emergencies where a ... -
Raw coal ore classification using image segmentation methods
(North-West University, 2018)The research done in order to complete this dissertation can be summarised as the investigation, implementation, analysis, and comparison of data analysis techniques with the intention to segment a digital image of a raw ... -
Re-engineering an engineering career
(North-West University, 2009)Re-engineering is an ongoing process of change that continues throughout a person's life. It includes all aspects of life, even your career and lifestyle as you continue to grow as an individual. There is no satisfaction ... -
Re-engineering the tender process at Tubular Track
(2015)In any organisation processes can be seen evolving throughout their lifecycle and play a deciding role in the efficiency of organisational activities. Tender processes are no different and with growing competitiveness and ... -
Reaction kinetics of the iron-catalysed decomposition of SO3
(2014)In this study the performance of pure, very fine iron (III) oxide powder was investigated as catalyst for the decomposition of sulphur trioxide into sulphur dioxide and oxygen. This highly endothermic reaction requires a ... -

The reactivity of South African limestone of variable quality as potential sorbents in wet flue gas desulphurisation
(North-West University (South Africa), 2019)According to the World Health Organisation (WHO) clean air is a basic requirement for the well-being and general health of every human being. The results of WHO assessments have shown that annually more than 2 million ... -
Real time remote heart rate & ECG monitoring for the modern sport scientist : a front end design
(North-West University, 2007)A need exists to optimise the efficiency of the way athletes are trained in the professional sports environment. Since it is a multiple variable problem with constraints, it provokes the need for sophisticated research, ... -
Real-time energy management in the cement industry
(North-West University, 2005)The purpose of this study was to investigate Demand-Side Management (DSM) opportunities in the South African cement industry. This was done by identifying four criteria that affect the DSM load shift process on a production ... -
Real-time power system oscillation monitoring using synchrophasor measurements
(North-West University (South Africa) , Potchefstroom Campus, 2015)Advanced Measurement Infrastructure (AMI) constitutes one aspect necessary to realise a Smart Grid. Advanced monitoring is necessary for reliable operation and control of a modern power system. Enabling measurement ... -
Recommendation on a suitable desalination process for the South African environment
(North-West University, 2010)Supplies of potable water from traditional sources have been increasingly depleted due to increasing world population and per capita water use. In South Africa fresh water is a vital, but scarce resource, distributed ... -
The reconciliation of the material balance of a natural gas processing plant
(North-West University, 2006)Accurate material balances serve as essential tools for controlling, evaluating and optimising petrochemical processes. In natural gas processing plants, where there are only phase separation processes and no chemical ... -
Reconfiguring deep-level mine dewatering systems for increased water volumes
(North-West University (South Africa), 2020)Deep-level mines are faced with a host of challenges that can pose a threat to the safety of underground mine employees. Significant among these threats is the risk of underground floods as a result of fissure water flowing ... -
Reconfiguring mine cooling auxiliaries for optimal operation
(North-West University (South Africa) , Potchefstroom Campus, 2016)Deep level gold mines utilise energy intensive cooling systems to maintain an acceptable underground working environment. The majority of these cooling systems are old as they were installed a few years after the mines’ ... -
Reconfiguring mine water reticulation systems for cost savings
(North-West University, Potchefstroom Campus, 2018)Rising electricity costs in South Africa force companies, including gold mines, to minimise their energy consumption (EC). More than 30% of the total energy demand for deep-level mines is consumed by the water reticulation ... -

Reconfiguring mining compressed air networks for cost savings
(2014)The world is currently experiencing major issues in the energy sector. The ever-growing human population, limited energy resources and the effect of greenhouse gas emissions have become major global concerns for the energy ... -
Recuperation of H2SO4 in the hybrid sulphur process using pervaporation
(North-West University, 2012)In this experimental study the sorption and pervaporation characteristics of commercial Nafion–117 and Nafion–212 membranes with mixtures of water (H2O) and sulfuric acid (H2SO4) were investigated. During experimentation ... -
Redefining the Griqualand West Centre of endemism
(North-West University (South Africa) , Potchefstroom Campus, 2016)The Griqualand West Centre (GWC) of plant endemism in the Northern Cape was defined and described in 2001 according to geological features and limited floristic data. Approximately 40 plant species were proposed to be ...
