The detailed nature of active central cluster galaxies
(Oxford Univ Press, 2013)We present detailed integral field unit observations of the central few kiloparsecs of the ionized nebulae surrounding four active central cluster galaxies (CCGs) in cooling flow clusters (Abell 0496, 0780, 1644 and ... -
Detailed spectral and morphological analysis of the shell type supernova remnant RCW 86
(EDP Sciences, 2018)Aims. We aim for an understanding of the morphological and spectral properties of the supernova remnant RCW 86 and for insights into the production mechanism leading to the RCW 86 very high-energy γ-ray emission. Methods. ... -
A detailed spectrophotometric investigation of the complexation of palladium(II) with chloride and bromide
(Elsevier, 2017)As the speciation of metal species, especially the noble metals, are crucial for recovery and separation purposes, the complex formation of Pd(II), with chloride and bromide respectively, has been investigated employing ... -

(Elsevier, 2019)Complex formation of mixed palladium (II) chloro-hydroxo and palladium(II) bromo-hydroxo complexes have been investigated employing spectrophotometry at 25 °C and an ionic strength of 1.0 M. Hyperquad Simulation and ... -
Detecting metal-poor gas accretion in the star-forming dwarf galaxies UM 461 and Mrk 600
(Oxford Univ Press, 2018)Using VIsible MultiObject Spectrograph (VIMOS)-integral field unit (IFU) observations, we study the interstellar medium (ISM) of two star-forming dwarf galaxies, UM 461 and Mrk 600. Our aim was to search for the existence ... -
The detection and molecular characterisation of Shiga Toxigenic Escheria coli (STEC) O157 strains from humans, cattle and pigs in the North-West Province, South Africa
(North-West University (South Africa), 2006)The prevalence and antibiotic resistant profiles of shiga-toxin producing Escherichia coli O 157 strains isolated from faeces samples of cattle, pigs and human stool samples were determined. The strains were further ... -
The detection and molecular characterisation of Shiga Toxigenic Escheria coli (STEC) O157 strains from humans, cattle and pigs in the North–West Province, South Africa
(2006)The prevalence and antibiotic resistant profiles of shiga-toxin producing Escherichia coli 0157 strains isolated from faeces samples of cattle, pigs and human stool samples were determined. The strains were further ... -
Detection and Molecular characterisation of Virulence Genes in Antibiotic Resistant Staphylococcus aureus from milk in the North West Province, South Africa
(North-West University, 2013)Staphylococcus aureus (S. aureus) is a common microorganism present on the skin and mucosal surfaces of humans and animals. However, a variety of infections, ranging from mild skin infections to severe infections such ... -
The detection and quantification of biomolecules in biological sample matrices
(North-West University (South-Africa), 2019)In the bodies of living humans and animals, endogenous biomolecules, and in particular the chemical messengers, play an essential role in the maintenance and functionality of physiological processes (Daintith, 2008; Gault ... -
Detection and quantification of clinically relevant plasmid-mediated AmpC beta-lactamase genes in aquatic systems
(IWA Publishing, 2020)The extent and impact of plasmid-mediated AmpC beta-lactamase genes (pAmpCs) prevalence in aquatic environments is poorly understood. The aim of this study was to detect and quantify pAmpCs from the aquatic environment. ... -
Detection of African horse sickness virus in Culicoides imicola pools using RT-qPCR
(Wiley, 2016)African horse sickness (AHS) is an infectious, non-contagious arthropod-borne disease of equids, caused by the African horse sickness virus (AHSV), an orbivirus of the Reoviridae family. It is endemic in sub-Saharan Africa ... -
Detection of African horse sickness virus in Culicoides imicola using real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR)
(2016)African horse sickness (AHS) is an infectious, non-contagious arthropod-borne disease of equids. The disease is caused by the African horse sickness virus (AHSV), a member of the genus Orbivirus, of the Reoviridae family. ... -
Detection of antibiotic resistant staphylococcus aureus from milk: a public health implication
(MDPI, 2015)The aim of this study was to investigate the occurrence, antibiotic susceptibility profiles, and virulence genes determinants of S. aureus isolated from milk obtained from retail outlets of the North-West Province, South ... -
Detection of atmospheric water vapour using the Global Positioning System
(North-West University, 2003)The Global Positioning System (GPS) has been used for more than a decade for the accurate determination of position on the earth's surface, as well as navigation. The system consists of approximately thirty satellites, ... -
Detection of endocrine disrupting compounds in abiotic and biotic matrices from the Phongola floodplain using tissue culture based bio-assays
(North-West University (South Africa), 2016)Increasing rates of urbanization, industrialisation, population growth and agricultural demand in South Africa have considerably decreased water quality leading to different forms of water pollution, which might be the ... -
Detection of gamma rays from a starburst galaxy
(AAAS, 2009)Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the remnants of which are thought to accelerate energetic cosmic rays up to energies of ~1015 electron volts. We report the detection ... -
Detection of large-scale Ly α absorbers at large angles to the radio axis of high-redshift radio galaxies using SOAR
