Application of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid for the different types of separations problem: Activity coefficients at infinite dilution measurements using gas-liquid chromatography technique
(Elsevier, 2016)The present work focussed on application of the environmental friendly 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ([BMIM]+[Tf2N]−) ionic liquid for the separations of (alkane/aromatic), (alkane/alk-1-ene), ... -
Application of a basic monitoring strategy for Cryptosporidium and Giardia in drinking water
(WRC (Water Research Commission), 2014)Despite the health risks associated with exposure to Cryptosporidium and Giardia, there is no uniform approach to monitoring these protozoan parasites across the world. In the present study, a strategy for monitoring ... -
The application of a macroinvertebrate indicator in afrotropical regions for pesticide pollution
(Hindawi, 2018)Many biotic integrity indices are not able to isolate community effects due to pesticide exposure as the communities also respond to other anthropogenic and natural stressors. A macroinvertebrate trait bioindicator system ... -
Application of a Sediment Quality Index for the assessment and monitoring of metals and organochlorines in a premier conservation area
(Springer, 2015)The physical and chemical characteristics of surface sediments from a leading conservation area, namely the Kruger National Park, were determined in order to identify potential stressors in the systems that may contribute ... -
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. ... -
