The need to conduct research on the impact of elephant on the environment prompted the construction of exclosures along two of the most important rivers in the Kruger National Park. Scientific research on these exclosures ...

We report on VERITAS very high energy (VHE; E ⩾ 100 GeV) observations of six blazars selected from the Fermi Large Area Telescope First Source Catalog (1FGL). The gamma-ray emission from 1FGL sources was extrapolated up ...
Die voorkoms van verteenwoordigers van die Ancylidae in Suid-Afrika is reeds in 1848 gerapporteer. Die eerste omvattende studie van hierdie familie in Suid-Afrika is egter eers in 1923 gepubliseer. Alhoewel verskeie bydraes ...

The HESS very-high-energy (VHE, E > 0.1 TeV) gamma-ray telescope system has discovered a new source, HESS J1747-248. The measured integral flux is (1.2 ± 0.3) × 10−12 cm−2 s−1 above 440 GeV for a power-law photon spectral ...
Internationally there is a growing demand for environmental impact assessment (EIA) to move away from its traditional focus towards delivering more sustainable outcomes. South Africa is an example of a country where the ...
High mortality rates caused by rotaviruses are associated with several strains such as G2, G8, G9, and G12 rotaviruses. Rotaviruses with G9 and G12 genotypes emerged worldwide in the past two decades. G2 and G8 rotaviruses ...
Infection of a single host cell with two or more different rotavirus strains creates conditions favourable for evolutionary mechanisms like reassortment and recombination that can generate novel strains. Despite numerous ...
