Demokratisering en standaardisering – Teenstrydige doelwitte vir inheemse tale?
(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2011)At fi rst blush, the two concepts, democratisation and standardisation, seem to be in confl ict if the objectives underlying the processes they describe are compared, in particular if they are applied to the fi eld of ... -
Demonstrating an interpretive data collection and analysis process for a DSR project
(Czech institute of academic education z.s, 2014)Design science research has two essential processes, design and evaluation, supported by various approaches. Two of these activities, namely problem identification and evaluation, require qualitative data to be gathered ... -
Demonstrating the benefits of impact assessment for proponents
(Taylor & Francis, 2015)This paper is a call for more studies that explicitly demonstrate the benefits of impact assessment to proponents. While the community of impact assessment practitioners generally believe that impact assessment is beneficial ... -
Demonstrating the value and importance of combining DNA barcodes and discriminant morphological characters for polystome taxonomy (Platyhelminthes, Monogenea)
(Elsevier, 2018)Polystomes are monogenean parasites that infest mainly semi aquatic vertebrates, such as amphibians and chelonians. Owing to the lack of discriminative morphological characters and because polystomes are considered to be ... -
Den frühchristlichen Wundergeschichten Sinn für die Gegenwart entlocken
(University of Catholique Louvain, 2015)Rudolf Bultmann setzte sein Gegenwartsverständnis dem Glauben an Wunder radikal entgegen. Ein Weltbild, das Raum für Wunder hatte, war in seiner Diktion 'erledigt'. So näherte er sich den frühchristlichen Wundergeschichten ... -
Dendrimers: a new class of corrosion inhibitors for mild steel in 1 M HCl: experimental and quantum chemical studies
(Elsevier, 2016)The inhibition properties of two ammonia cored dendrimers have been investigated for mild steel corrosion in 1 M hydrochloric acid solution using chemical, electrochemical, surface and quantum chemical calculation methods. ... -
Denied investment: a case of community member’s attitudes towards volunteering in corporate social investment initiatives
(International Foundation For Research & Development IFRD), 2015)Companies use corporate social responsible investment (CSI) initiatives to contribute to the wellbeing of the society they operate in. South African companies continue to increase their involvement in CSI initiatives in ... -
Denjoy-Wolff theorems for Hilbert’s and Thompson’s metric spaces
(Springer, 2018)We study the dynamics of fixed point free mappings on the interior of a normal, closed cone in a Banach space that are nonexpansive with respect to Hilbert’s metric or Thompson’s metric. We establish several Denjoy-Wolff ... -
Denke as krisisterrein in die verskynsel van kerkkrimping by tradisioneel afrikaanssprekende susterkerke
(AOSIS, 2013)Since little can be done, humanly speaking, to address the numerous factors influencing the decline of churches, it is obvious that everything humanly possible must be done. Thinking plays a major role in ecclesiology. ... -
Dense sampling of bird diversity increases power of comparative genomics
(Nature Research, 2020)Whole-genome sequencing projects are increasingly populating the tree of life and characterizing biodiversity1,2,3,4. Sparse taxon sampling has previously been proposed to confound phylogenetic inference5, and captures ... -
Density and speed of sound measurements of imidazolium-based ionic liquids with acetonitrile at various temperatures
(2014)In the present study, the interactions between acetonitrile and imidazolium-based ionic liquids (ILs) were discussed in terms of density (ρ) and speed of sound (u) measurements. The ILs used in this study were 1-ethyl-3- ... -
Density and speed of sound of 1-ethyl-3-methylimidazolium ethyl sulphate with acetic or propionic acid at different temperatures
(Elsevier, 2014)In this work, new density, ρ, and speed of sound, u, were measured for IL, acetic acid, propionic acid, and their binary systems {IL (x1) + acetic or propionic acid (x2)} at 293.15, 298.15, 303.15, 308.15 and 313.15 K under ... -
Density dependence and temporal plasticity of competitive interactions during utilisation of resources by a community of lepidopteran stemborer species
(Wiley, 2017)Interactions within and between species sharing the same resources are characterised by competition or facilitation, and can be influenced by factors such as larval numbers and phenotypic plasticity of the interactions. ... -
Density functional theory calculation of Ti3C2 MXene monolayer as catalytic support for platinum towards the dehydrogenation of methylcyclohexane
(Elsevier, 2020)The need for sustainable energy systems and reducing greenhouse gas emissions are key drivers in the development of liquid hydrogen organic carriers (LOHCs). Density functional theory calculations were performed on the ... -
Density functional theory molecular modelling and experimental particle kinetics for CO2-char gasification
(Elsevier, 2015)Experimental measurements and DFT atomistic modelling were conducted to elucidate the mechanisms for gasification chemistry of char with CO2 gas. The molecular models used were based on experimental representations of coal ... -
Density functional theory prediction of the aqueous speciation of ZrF4 and HfF4
(SAIMM, 2018)Computational chemistry was used to make predictions regarding the stepwise hydrolysis and fluoride dissociation reactions of ZrF4 and HfF4 in aqueous solutions. Specifically, density functional theory was used to predict ... -
Density functional theory studies of the SrC and SrN compounds
(Elsevier, 2019)The structural, magnetic, elastic, dynamical and thermodynamic properties of the SrC and SrN compounds were studied using density functional theory. We found that the CsCl and NaCl phases have the lowest energy configurations ... -
Density functional theory study with and without COSMO of H2SO4 reactions in an aqueous environment for metal extraction
(Wiley, 2019)In a recent study investigating the suitability of solvent extraction (SX) for the separation of Ta and Nb, it was shown that speciation data would be required to help explain the data obtained. As traditional speciation ... -
Density-dependent growth response and sensitivity of Meloidogyne incognita to Maerua angolensis and Tabernaemontana elegans: Card model
(Taylor & Francis, 2019)Curve-fitting Allelochemical Response Dosage (CARD) computer-based model has proven to be a valuable tool in the definition of dosage response relationships between organisms and various plant extracts. Its use in the ... -
Density-dependent spatial patterning of woody plants differs between a semi-arid and a mesic savanna in South Africa
(Elsevier, 2018)Savannas can be defined by the co-dominance of grasses and trees. Interactions between these two life forms are relatively well studied, whereas tree-tree interactions attracted increased attention only recently. However, ...
