Metallothionein induction as indicator of low level metal exposure to aquatic macroinvertebrates from a relatively unimpacted river system in South Africa
(Springer, 2017)
The Marico River is relatively unaffected by anthropogenic activities. However, metal concentrations—mainly from natural sources—occasionally exceed environmental quality guidelines. Macroinvertebrates are capable to react ...
Effectivity of phenol during solvent extraction of a South African bituminous coal under mild conditions
(ACS, 2017)
Solvent extraction of a South African bituminous coal was carried out under mild conditions (<400 °C) with a holding time of 20 min and an initial nitrogen (N2) pressure of 6 MPa. Thermal degradation of coal with phenol ...
Student development and soft skills: IT-students at a university in South Africa
(IADIS, 2017)
The aim of this paper is to determine whether IT-students are aware of soft skills and the importance thereof, and to research the students perceptions on the importance and development of their own soft skills. More and ...

Age-dating luminous red galaxies observed with the Southern African Large Telescope
(Oxford Univ Press, 2017)
We measure a value for the cosmic expansion of H(z) = 89 ± 23(stat) ± 44(syst) km s−1 Mpc−1 at a redshift of z ≃ 0.47 based on the differential age technique. This technique, also known as cosmic chronometers, uses the age ...
Ultramafic geoecology of South and Southeast Asia
(Springer, 2017)
Globally, ultramafic outcrops are renowned for hosting floras with high levels of endemism, including plants with specialised adaptations such as nickel or manganese hyperaccumulation. Soils derived from ultramafic regoliths ...
