Aalwurms by sojabone raak al hoe erger
(Netwerk24, 2020)Die toename in aalwurms wek kommer in die sojaboonbedryf. Namate die produksie styg, neem die blootstelling aan siektes en plae ook toe. Wisselbou en kultivars met genetiese weerstand is dalk nie doeltreffend genoeg om ... -
'Aan die' en 'besig' in Afrikaanse progressiwiteitskonstruksies: 'n korpusondersoek (2)
(Suid–Afrikaanse Akademie vir Wetenskap en Kuns, 2015)In 'n tweetal artikels (hierdie artikel en Breed & Van Huyssteen 2014) stel ons ondersoek in na die wyse waarop twee perifrastiese konstruksies, te wete die VKOP besig om te V- en die VKOP aan die V-konstruksies, gebruik ... -
Aanmelding van seksuele misbruik deur adolessente
(Department of Social Work, University of Stellenbosch, 2011)There is a high incidence of sexual abuse of adolescents in South Africa. Despite this, only a small number of sexual abuse cases are reported immediately. The main purpose of this research was to investigate the reasons ... -
Aantekening : internasionale strafregtelike jurisdiksie vir die Afrika-hof : problematiese aspekte en die implikasies daarvan.
(Litnet Akademies, 2014)International criminal jurisdiction for the African court: Problematic aspects and the implications thereof This note identifies and describes a number of problematic aspects arising from the conferral of international ... -
Aantekening: om globale omgewingsreg en -regulering in die antroposeen te herbedink
(Litnet, 2013)The word anthropocene describes a new geological epoch that follows the holocene epoch. It is the signifier of the period in which people have a devastating and overwhelming impact on the earth and its systems. The ... -
Aard van neuro-motoriese inperkings by 7-en 8-jarige leerders met leerhindernisse
(2014)This study aimed to determine the extent of neuro-motor impairments in 7 to 8 year-old children with barriers to learning and the possible relationship of such impairment to specific learning areas. ... -
Ab initio insights on the effect of embedding lanthanide atoms on nitrogenated holey doped graphene (g-C2N)
(RSC, 2018)Within the density functional theory formalism with the Hubbard correction (DFT+U) we explore how the structural, electronic and magnetic properties of nitrogenated holey doped graphene (g-C2N) can be tuned through embedding ... -
An AB initio model for cosmic-ray modulation
(IOP Publishing, 2013)A proper understanding of the effects of turbulence on the diffusion and drift of cosmic rays (CRs) is of vital importance for a better understanding of CR modulation in the heliosphere. This study presents an ab initio ... -
An AB initio model for the modulation of galactic cosmic-ray electrons
(IOP Publishing, 2013)The modulation of galactic cosmic-ray electrons is studied using an ab initio three-dimensional steady state cosmicraymodulation code in which the effects of turbulence on both the diffusion and drift of these cosmic-rays ... -
Ab initio studies of the structural, electronic and magnetic properties of stannite CuFe 2 -III-VI 4 (III = Al, Ga, In and VI = S, Se, Te) alloys
(Elsevier, 2020)The structural, magnetic and electronic properties of stannite CuFe2-III-VI4 (where III = Al, Ga, In and VI = S, Se, Te) quaternary alloys were investigated using the full-potential augmented plane wave and local states ... -
An ab initio study on the transition path of carbon dioxide at high pressure: evidence for a new intermediate P(4)over-barm2 phase
(Elsevier, 2019)The structural and dynamical behaviour of seventeen solid polymorph of the non-molecular CO2 compound was evaluated using the full potential linear augmented plane wave method (FP-LAPW) in the framework of density functional ... -
Abalone growth and associated aspects: now from a metabolic perspective
(Wiley, 2018)Worldwide, there are approximately 100 Haliotis species, more commonly known as abalone or ‘Paua’ in New Zealand, ‘Venus's‐ears’ in Greece, ‘Awabi’ in Japan, ‘Perlemoen’ in South Africa and ‘Ormers’ in Europe. Regardless ... -
Aberrant synthesis of ATP synthase resulting from a novel deletion in mitochondrial DNA in an African patient with progressive external ophthalmoplegia
(Springer, 2010)A young, adult, African male patient presented with progressive proximal muscle weakness, external ophthalmoplegia and ptosis, as well as cardiac conduction abnormalities resembling Kearns–Sayre syndrome (KSS). Magnetic ... -
The ablation of gas clouds by blazar jets
(EDP Sciences, 2020)Context. Flaring activity in blazars can last for vastly different timescales, and it may be the result of density enhancements in the jet flow that result from the intrusion of an interstellar cloud into the jet. Aims. ... -
Abnormal repetitive behaviors in zebrafish and their relevance to human brain disorders
(Elsevier, 2019)Abnormal repetitive behaviors (ARBs) are a prominent symptom of numerous human brain disorders and are commonly seen in rodent models as well. While rodent studies of ARBs continue to dominate the field, mounting evidence ... -
Abnormal tricarboxylic acid cycle metabolites in isovaleric acidaemia
(Springer, 2009)Background Although a number of abnormal diagnostic metabolites have previously been described in the urine of patients with isovaleric acidaemia (IVA), they do not fully explain the clinical symptoms associated with this ... -
Above-cloud aerosol optical depth from airborne observations in the southeast Atlantic
(EGU, 2020)The southeast Atlantic (SEA) region is host to a climatologically significant biomass burning aerosol layer overlying marine stratocumulus. We present the first results of the directly measured above-cloud aerosol optical ... -
The absence of diffusion in the South African short rate
(SASA, 2019)In the field of Financial Mathematics, stochastic differential equations are used to describe the dynamics of interest rates. An example is a model for the short rate, which is a mathematically defined rate not directly ... -
Absolute reflectance of a concave mirror used for astro-particle physics experiments
(Elsevier, 2019)The absolute reflectance of a reflector and its point spread function are the key parameters of a telescope for measuring light flux. Typically, one is using low-cost technologies for producing mirrors for the needs of ... -
Absorption of the novel artemisinin derivatives artemisone and artemiside: potential application of Pheroid™ technology
(Elsevier, 2011)Artemisinins have low aqueous solubility that results in poor and erratic absorption upon oral administration. The poor solubility and erratic absorption usually translate to low bioavailability. Artemisinin-based monotherapy ...
