Fatigue, substance use and sick leave of employees in a mining environment
(North-West University, Vaal Triangle Campus, 2018)A major concern for and challenge to the mining industry are the increasing perceptions of employee fatigue at all levels of the organisational structure. It is compulsory, by legislation that mines in South Africa report ... -
Fatty acid and micronutrient intake and status in association with allergy among pregnant urban women in South Africa
(North-West University, 2018)Background: Allergy has become a global problem, consequently reaching epidemic proportions. Worldwide, in both developed and developing countries, the prevalence of allergic disease is rising substantially, with an estimated ... -
Fatty acid metabolome extraction from mycobacterial cells for GC-MS metabolomics analysis
(Humana, 2019)Metabolomics is becoming an increasingly popular research tool for identifying new biomarkers, which can, among other applications, be applied to elucidate various microbial growth and virulence mechanisms. Since the lipid ... -
Fatty acid status and dietary intake of children and their caregivers from three distinct communities
(2013)Background: Dietary fat intake particularly of omega-3 and omega-6 fatty acids play an important role in growth and development and influence the risk of nutrition related non communicable diseases. These dietary intakes ... -
Fault detection and characterisation in pressurised water reactors using real-time simulations
(Elsevier, 2011)The use of real-time plant simulators running in parallel with a nuclear plant to predict the control system behaviour and highlighting unexpected plant behaviour is presented. The study is performed on a 910 MW Generation ... -
Fault detection techniques on active magnetic bearing systems and electrical machines: a review
(SPC, 2018)This paper provides a review on fault detection techniques on active magnetic bearing systems and electrical machines. The following non-linear processing fault detection techniques are discussed in this paper: 1) Time ... -
Fault diagnosis of generation IV nuclear HTGR components. Part 1. The error enthalpy-entropy graph approach
(Elsevier, 2012)Fault diagnosis (FD) is an important element in modern nuclear power plant (NPP) diagnostic systems. In this respect, FD of generation II and III water-cooled nuclear energy systems has become an active research topic to ... -
Fault diagnosis of generation IV nuclear HTGR components. Part 2. The area error enthalpy-entropy graph approach
(Elsevier, 2012)The second paper in a two part series presents the area error method for generation of representative enthalpy–entropy (h–s) fault signatures to classify malfunctions in generation IV nuclear high temperature gas-cooled ... -
Fault diagnostic system for predictive maintenance on a Brayton cycle power plant
(North-West University, 2004)Model-based fault detection and diagnostic systems have become an important solution (Munoz & Sanz-Bobi, 1998:178) in the industry for preventive maintenance. This not only increases plant safety, but also reduces down ... -
Fault identification and diagnosis for telephone exchange building facilities
(North-West University, 2005)Heating, ventilating and air conditioning (HVAC) systems consume 43 % of the energy used by buildings. This percentage grows when the HVAC system operates with malfunctions. Fault detection and diagnosis (FDD) methods ... -
A fault-tolerant wireless distributed computing platform for robot swarms
(North-West University (South Africa), 2020)A novel use of drone swarms was demonstrated by Intel during the opening ceremony of the 2018 Winter Olympics when hundreds of LED-equipped drones flew in precise formation to create a visual spectacle. This show was ... -

Fe(II) and Fe(III) complexes of N-ethyl-N-phenyl dithiocarbamate: electrical conductivity studies and thermal properties
(Elsevier, 2014)The electrical conductivity and thermal properties of Fe complexes in different oxidation states of (II)and (III) have been studied using the compounds Fe (II) bis (N-ethyl-N-phenyl dithiocarbamate), andFe (III) tris ... -
The fear of the Lord as key pastoral guidance, for a healing ministry to survivors of generational ritual abuse
(North-West University, 2010)Generational ritual abuse within satanic or fertility (abusive witchcraft) cults is a controversial subject. This study shows that, while not all reported memories may be true, False Memory Syndrome is not an intrinsic ... -
The feasibility and application of multi–layer vacuum insulation for cryogenic hydrogen storage
(North-West University, 2011)A need was identified to test multi–layer vacuum super insulation (MLVSI) used in cryogenic applications for hydrogen storage. The study focuses on the application of commercially available MLVSI to a locally patented ... -
The feasibility of a green procurement practice for low cost housing in the City of Tshwane Metropolitan Municipality
(North-West University, 2009)Green Procurement is defined as taking into account environmental criteria for goods and services to be purchased in order to ensure that the related environmental impact is minimized (Incite Sustainability, 2008: vii). ... -
The feasibility of a youth magazine as a means of communication and information sharing in the Mafikeng area of the North West Province
(North-West University (South Africa), 2008)The aim of this study was to investigate the feasibility of a youth magazine as means of information sharing and communication in the Mafikeng area of the North West Province. The study focussed on students at the North ... -
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 ... -
Feasibility of commercial maritime nuclear propulsion
(North-West University, 2009)The goal of this study is to make the unique benefits of modern nuclear technology available to a wider sphere. The basic hypothesis is that the time is ripe to re-investigate nuclear propulsion for commercial shipping. ...
