The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
(IEEE, 2016)It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that ... -
The effect of an offset-dipole magnetic field on the Vela pulsar’s γ-ray light curves
(SAIP, 2015)Over the past six years, the Fermi Large Area Telescope has detected more than 150 γ-ray pulsars, discovering a variety of light curve trends and classes. Such diversity hints at distinct underlying magnetospheric and/or ... -
The effect of aqueous phase recirculation during hydrothermal liquefaction of spent coffee grounds
(EARET, 2018)Batch hydrothermal liquefaction of spent coffee grounds was done in this study. The effect of subsequent diluted aqueous phase recirculation was studied at a constant temperature of 275 °C and residence time of 10 ... -
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
(EARET, 2018)The effect that 6 different biomass feedstocks have on biochar was investigated. The biochar was produced through hydrothermal liquefaction at temperatures of 260˚C and 300˚C. The effect of temperature was also investigated. ... -
The effect of BPR on organizational strategy and the role of SDMS: a case of South Africa’s merged higher education institutions
(IBIMA, 2012)Changes in organisations due to various factors such as technological advancements or competition may bring the effect of change to certain business processes. This in turn invokes business process re-engineering (BPR) and ... -
The effect of different magnetospheric structures on predictions of gamma-ray pulsar light curves
(South African Institute of Physics, 2012)The second pulsar catalogue of the Fermi Large Area Telescope (LAT) will contain in excess of 100 gamma-ray pulsars. The light curves (LCs) of these pulsars exhibit a variety of shapes, and also different relative phase ... -
The effect of different magnetospheric structures on predictions of gamma-ray pulsar light curves
(SAIP, 2014)The second pulsar catalogue of the Fermi Large Area Telescope (LAT) will contain in excess of 100 gamma-ray pulsars. The light curves (LCs) of these pulsars exhibit a variety of shapes, and also different relative phase ... -
Effect of dipole corrections and spin orbit coupling on tungsten dichalcogenides monolayer: a in silico first principles study
(IEEE, 2018)The structural and electronic properties of tungsten dichalogenides compounds (WS 2 , WSe 2 , WTe 2 ) were investigated from first principles calculations. We found that the structural and electronic properties changed ... -
The effect of entrapment of a peptide in Pheroid® on pharmacokinetics and testosterone levels
(Elsevier, 2019)Goserelin is a peptide drug that suppresses levels of testosterone and oestradiol [1]. The current formulation is presented in a sustained-release depot with several approved indications such as treatment of endometriosis, ... -
THE EFFECT OF ENTREPRENEURIAL ORIENTATION OF SMES AND LABOUR-INTENSIVENESS IN THE CONSTRUCTION INDUSTRY
(IBC, 2021)Human resources are valuable and must be well managed to obtain optimal value. Best performances, entrepreneurial orientation and the labour-intensive nature of the construction industry are important factors to ... -

Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
(EARET, 2018)The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ... -
The effect of molar ratio and flow velocity on the surface area required for pertraction of a Zr/Hf mixture
(IOP, 2019)Zirconium (Zr) and hafnium (Hf) need to be separated before being used in nuclear applications. Equilibria data have shown that Hf can be selectively extracted over Zr from a sulphate medium using organophosphorus ... -
Effect of operating parameters on hydrothermal liquefaction of sugarcane bagasse
(EARET, 2018)Hydrothermal liquefaction (HTL) is a thermochemical process that produces various products from lignocellulosic feedstocks. In this study sugar cane bagasse was used as feedstock for HTL. Experiments were carried out ... -
The effect of real network phase disturbances on the calculation of IEC 61000-4-30 parameters
(IEEE, 2014)Real life network dynamic phenomena are used to demonstrate how the calculation of IEC 61000-4-30 parameters can be affected. The voltage frequency can change instantaneously at a point in the network due to a shift in the ... -
Effect of temperature and cathode material on power production in an earthenware microbial fuel cell
(EARET, 2018)This study investigates the performance of microbial fuel cells (MFCs) fed with municipal sewage water considering parameters such as temperature and cathode materials. Single chamber ceramic MFCs with the cathode exposed ... -
