The effect of carbonaceous reductant selection on chromite pre-reduction
(Springer, 2017)Ferrochrome (FeCr) production is an energy-intensive process. Currently, the pelletized chromite pre-reduction process, also referred to as solid-state reduction of chromite, is most likely the FeCr production process ... -
The effect of casino employees demographic variables on quality of work-life domains
(AJHTL, 2015)With over 38 casinos in South Africa, to be the most sought after casino, quality service offered by casino employees will be the competitive advantage of attracting and retaining customers. The purpose of this article is ... -
Effect of chronic N-acetyl cystine administration on oxidative status in the presence and absence of induced oxidative stress in rat striatum
(Springer, 2008)Antioxidants have possible therapeutic value in neurodegenerative disorders, although they may have pro-oxidant effects under certain conditions. Glutathione (GSH) is a key free radical scavenger. N-acetylcysteine (NAC) ... -
The effect of coal size on PM2.5 and PM-bound polycyclic aromatic hydrocarbon (PAH) emissions from a domestic natural cross-draft stove
(Elsevier, 2020)Residential coal combustion has played an important role in the domestic energy supply of Northern China for many decades and will do so for the foreseeable future, although it is also an important contributor to severe ... -
Effect of continuous aerobic vs. interval training on selected anthropometrical, physiological and functional parameters of adults with Down syndrome
(Wiley, 2016)Background A large percentage of adults with Down syndrome (DS) are overweight and have extremely low aerobic capacities compared with the general population and persons with intellectual disability without DS. Previous ... -
The effect of cooperative learning on the thinking skills development of Foundation Phase learners
(Taylor & FrancisUnisa, 2014)We report on the findings obtained from a mixed-method study conducted in South Africa with a conveniently and purposively selected sample of 60 Grade 3 learners and their two teachers. The aim was to establish the thinking ... -
The effect of crystalline phase (anatase, brookite and rutile) and size on the photocatalytic activity of calcined polymorphic titanium dioxide (TiO2)
(Elsevier, 2018)The effect of thermal treatment on the morphology (crystalline phase and size) and photocatalytic activity of freshly prepared TiO2 nano-powder is communicated. TiO2 nano-powders, prepared by hydrolyzing titanium ... -
Effect of cultivar, nitrogen application rate and stage of harvesting on yield and nutritive value of perennial ryegrass (Lolium perenne L.)
(Range Management Society of India, 2016)This experiment consisted of a factorial combination of seven perennial ryegrass cultivars, two levels of nitrogen fertilizer (30 and 60 kg ha?1), and three harvesting stages (60, 75 and 90 days after planting; DAP) and ... -
The effect of different host plants on development and survival of Nysius natalensis (Hemiptera: Orsillidae)
(Oxford University Press, 2015)Nysius natalensis Evans (Hemiptera: Orsillidae) is a pest of sunflower in South Africa. Adults invade sunflower fields from their weedy hosts. The host plant suitability for development and survival and the effect of ... -
The effect of different host plants on the reproduction and longevity of Nysius natalensis
(Wiley-Blackwell, 2012)Nysius natalensis Evans (Hemiptera: Orsillidae) is a pest of sunflower in South Africa. Adults invade sunflower fields from their weedy hosts which occur inside crop fields and on surrounding headlands. The host plant ... -
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 different water regimes on nematode reproduction, root galling, plant growth and yield of lowland and upland Asian rice varieties grown in two soil types infested by the rice root–knot nematode Meloidogyne graminicola
(Russian Academy of Sciences, 2015)In a screenhouse experiment, plants of the lowland rice variety Thihtayin and the upland rice variety Kone Myint 2 were grown in two soil types (clay loam and sandy loam), inoculated with 3,000 Meloidogyne graminicola ... -
The effect of diffusion on the particle spectra in pulsar wind nebulae
(IOP Publishing, 2013)A possible way to calculate particle spectra as a function of position in pulsar wind nebulae is to solve a Fokker–Planck transport equation. This paper presents numerical solutions to the transport equation with the ... -
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 drift on the evolution of the electron/positron spectra in an axisymmetric pulsar wind nebula
(IOP Publishing, 2014)Charged particles propagating through a structured magnetic field are subject to drift motion. The primary aim of the present paper is therefore to investigate the effects of gradient, curvature, and neutral sheet drift ... -
Effect of drying method on the chemical composition of leaves from four tropical tree species
(University of West Indies Press, 2014)Drying techniques are an important variable in forage evaluation because they affect the accuracy with which the composition of fresh plant material is determined. This study investigated the effect of five drying methods ... -
