The application of artificial mussels in conjunction with transplanted bivalves to assess elemental exposure in a platinum mining area
(MDPI, 2020)There is increasing evidence that platinum group elements (PGE) are pollutants of emerging concern worldwide. Limited information exists on levels, particularly in regions where PGEs are mined. A passive sampling device ... -
The application of behavioural thresholds to analyse collective behaviour in information security
(Emerald, 2017)Purpose The purpose of this study is to perform an exploratory investigation into the feasibility of behavioural threshold analysis as a possible aid in security awareness campaigns. Design/methodology/approach Generic ... -
Application of Bluetongue Disabled Infectious Single Animal (DISA) vaccine for different serotypes by VP2 exchange or incorporation ofchimeric VP2
(Elsevier, 2015)Bluetongue is a disease of ruminants caused by the bluetongue virus (BTV). Bluetongue outbreaks can be controlled by vaccination, however, currently available vaccines have several drawbacks. Further, there are at least ... -
Application of evolutionary algorithms to develop a rule set for assessing the rehabilitation status of asbestos mines in South Africa
(Springer Link, 2013)Asbestos mining has left a legacy of pollution in former mining areas that continues to negatively affect both the environment and local communities. In 2007, the Rehabilitation Prioritisation Index was developed as a ... -
Application of halloysite clay nanotubes as a pharmaceutical excipient
(Elsevier, 2017)Halloysite nanotubes, a biocompatible nanomaterial of 50–60 nm diameter and ca. 15 nm lumen, can be used for loading, storage and sustained release of drugs either in its pristine form or with additional polymer complexation ... -
Application of Mass Spectrometry as Rapid Detection Tool in Plant Nematology
(Taylor and Francis INC, 2014)Plant-parasitic nematodes (PPNs) are serious pests causing important crop losses worldwide. Accurate identification of PPNs is essential to plant pathogen diagnostics and, thus, plant disease management. Classification of ... -
Application of membrane technology in a base metal refinery
(SAIMM, 2013)Nanofiltration (NF) has attracted much attention over the past few years due to the reduced energy consumption compared to reverse osmosis (RO) and better separation performance compared to ultrafiltration (UF). Although ... -
The application of metabolomics toward pulmonary tuberculosis research
(Elsevier, 2019)In the quest to identify novel biomarkers for pulmonary tuberculosis (TB), high-throughput systems biology approaches such as metabolomics has become increasingly widespread. Such biomarkers have not only successfully been ... -
Application of Mhaskar-Prestin operators to the convergence of orthonormal expansions
(Wiley, 2010)Let I be either R or (−1, 1),andletW : I → (0, ∞). Assume that W 2 is a weight. We study the quasi-interpolatory polynomial operators τ l,n,m introduced by Mhaskar and Prestin, for Freud weights, Erd˝os weights, and ... -
Application of multivariate statistics and toxicity indices to evaluate the water quality suitability for fish of three rivers in the Kruger National Park, South Africa
(NISC, 2015)The water quality of the Olifants, Letaba and Luvuvhu rivers within the Kruger National Park was assessed for their suitability to sustain fish populations. Since water quality assessments result in huge datasets, principal ... -
Application of near infrared reflectance spectroscopy to the nutritional assessment of tree leaves as potential protein supplements for ruminants
(Trop. Agric. (Trinidad), 2017)The utility of near infrared reflectance spectroscopy (NIRS) as a rapid nutritional evaluation tool is not yet fully defined for a number of non-conventional feedstuffs, which are considered to be of low economic value. ... -
Application of new isonicotinamides as a corrosion inhibitor on mild steel in acidic medium: Electrochemical, SEM, EDX, AFM and DFT investigations
(Elsevier Science Bv, 2015)Corrosion inhibition effect of 2-(2-(2-phenyl)-3-(isonicotinamido)-4-oxothiazolidin-5-yl) acetic acid (PITA) and N-(2-phenyl-4-oxothiazolidin-3-yl)-isonicotinamide (POTI) on mild steel corrosion in 15% HCl solution was ... -
Application of novel Anion-Exchange Blend Membranes (AEBMs) to vanadium redox flow batteries
(MDPI, 2018)Both cation-exchange membranes and anion-exchange membranes are used as ion conducting membranes in vanadium redox flow batteries (VRFBs). Anion-exchange membranes (AEMs) are applied in vanadium redox flow batteries due ... -
Application of Sm0.8Sr0.2Fe1-xCoxO3-δ (x = 0.2, 0.5, 0.8) perovskite for the oxygen evolution reaction in alkaline media
(Springer, 2019)A new type of perovskite, i.e. Sm0.8Sr0.2Fe0.8Co0.2O3-δ (SSFC1), Sm0.8Sr0.2Fe0.5Co0.5O3-δ (SSFC2), and Sm0.8Sr0.2Fe0.2Co0.8O3-δ (SSFC3) were (i) synthesised by employing a sol gel method with subsequent calcination at 1000 ... -
An application of space-for-time substitution in two post-mining chronosequences under rehabilitation
(Taylor & Francis, 2011)Long-term monitoring of post-mining rehabilitation is inherently difficult and cannot be replicated, making the application of traditional experimental and statistical approaches for quantitative assessment of rehabilitation ... -
Application of Taguchi method to optimize garlic essential oil nanoemulsions
