Characterisation of Escherichia coli O157 strains from humans, cattle and pigs in the North-West Province, South Africa
(Elsevier Science Limited, 2008) -
The characterisation of slow-heated inertinite- and vitrinite-rich coals from the South African coalfields
(Elsevier, 2015)The development of coal char structures with pyrolysis has been extensively investigated but has traditionally been focused on the carboniferous coals in the northern Hemisphere. In this investigation, the properties of ... -
Characterisation of some Scutellonema species (Tylenchida: Hoplolaimidae) occurring in Botswana, South Africa, Costa Rica and the USA, with description of S. clavicaudatum sp. n. and a molecular phylogeny of the genus
(Brill, 2017)The genus Scutellonema contains more than 40 species of spiral nematodes with enlarged phasmids called scutella. In this study, we provide morphological and molecular characterisation of S. clavicaudatum sp. n., S. ... -
Characterisation of sub-micron particle number concentrations and formation events in the western Bushveld Igneous Complex, South Africa
(EGU, 2012)South Africa holds significant mineral resources, with a substantial fraction of these reserves occurring and being processed in a large geological structure termed the Bushveld Igneous Complex (BIC). The area is also ... -
Characterisation of the influence of genetic variations on the enzyme activity of a recombinant human glycine N-acyltransferase
(Elsevier, 2013)Human glycine N-acyltransferase (human GLYAT) detoxifies a wide range of endogenous and xenobiotic metabolites, including benzoate and salicylate. Significant inter-individual variation exists in glycine conjugation capacity. ... -
Characterisation of the inorganic chemistry of surface waters in South Africa
(Water Research Commission, 2011)The main purpose of this study was to determine a simple inorganic chemistry index that can be used for all surface waters in South Africa, in order to characterise the inorganic chemistry of surface waters. Water quality ... -
Characterisation of the Woody assemblages of Zululand coastal thronveld along the Nseleni River
(South African National Parks, 2008) -
Characterisation of Xanthomonas campestris pv. campestris isolates from South Africa using genomic DNA fingerprinting and pathogenicity tests
(Springer, 2012)The genetic diversity of Xanthomonas campestris pv. campestris isolates from South Africa was evaluated using 28 isolates obtained from the Johannesburg Fresh Produce Market. Samples were collected from cabbage supplies ... -
Characterisation tools development for PEM electrolysers
(Elsevier, 2014)Electrochemical impedance spectroscopy (EIS), current interrupt (CI) and current mapping (CM) were investigated as in-situ characterisation tools for PEM electrolysers. A 25 cm2 cell with titanium anode and carbon cathode ... -
Characterising non-structural protein NS4 of African horse sickness virus
(Public Library of Science, 2015)African horse sickness is a serious equid disease caused by the orbivirus African horse sickness virus (AHSV). The virus has ten double-stranded RNA genome segments encoding seven structural and three non-structural proteins. ... -
Characterising particulate organic nitrogen at a savannah-grassland region in South Africa
(MDPI, 2019)Although atmospheric organic N compounds are considered to be important, especially in new particle formation and their contribution to brown carbon, these species are not that well understood. This can be partially ... -
Characterising the long-term variability of blazars in leptonic models
(MDPI, 2019)Most research on blazar variability focuses on individual flares to explain acceleration and radiation mechanisms and improve on current models. These short-time events (being minutes, hours, or days) might not be ... -
Characterising the metabolic differences related to growth variation in farmed Haliotis midae
(Elsevier, 2018)The South African abalone farming industry is entirely based on Haliotis midae, which has been commercially cultured with great success the last 20 years. Even though abalone are cultivated under identical farming conditions, ... -
Characterising the VHE diffuse emission in the central 200 parsecs of our Galaxy with H.E.S.S.
(EDP Sciences, 2018)The diffuse very high-energy (VHE; >100 GeV) γ-ray emission observed in the central 200 pc of the Milky Way by H.E.S.S. was found to follow dense matter distribution in the central molecular zone (CMZ) up to a longitudinal ... -
Characteristic function-based inference for GARCH models with heavy-tailed innovations
(Taylor & Francis, 2017)We consider estimation and goodness-of-fit tests in GARCH models with innovations following a heavy-tailed and possibly asymmetric distribution. Although the method is fairly general and applies to GARCH models with arbitrary ... -
The characteristics of an abstract system for the transfer of property in South African law as distinguished from a causal system
(NWU, 2012)Two divergent systems are usually differentiated between when it comes to the way in which real rights are transferred from one person to another, namely abstract and causal systems. In this article the features of each ... -
Characteristics of columnar aerosol optical and microphysical properties retrieved from the sun photometer and its impact on radiative forcing over Skukuza (South Africa) during 1999-2010
(Springer, 2017)The detailed analysis of columnar optical and microphysical properties of aerosols obtained from the AErosol RObotic NETwork (AERONET) Cimel sun photometer operated at Skukuza (24.98° S, 31.60° E, 150 m above sea level), ... -
The characteristics of compassionate care during childbirth according to midwives: a qualitative descriptive inquiry
(BMC, 2020)Abstract Background: Although compassion is considered to be of prime importance in nursing and midwifery, there is no clear understanding of what compassionate care in childbirth entails, and how midwives perceive ... -
Characterization and imaging of lead distribution in bones of lead-exposed birds by ICP-MS and LA-ICP-MS
(Elsevier, 2018)Lead (Pb) poisoning in raptors and water birds is a serious problem in many countries. However, only a small fraction of Pb poisoning has been detected in birds. Bone specimens may be useful indices of Pb exposure because ... -
Characterization and modelling of a customs operation
(NWU, 2018)Effective risk management is a prerequisite to find an acceptable balance between the objectives of a customs operation and the streamlined flow of goods. This requires the use of well-designed customs risk management models ...
