(Elsevier Science, 2011)
    The Sculptor and Carina dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total of 11.8 h and 14.8 h of high quality data, ...

    The quasar PKS 1510−089 (z = 0.361) was observed with the H.E.S.S. array of imaging atmospheric Cherenkov telescopes during high states in the optical and GeV bands, to search for very high energy (VHE, defined as E ≥ 0.1 ...

    Aims. We present very high energy (VHE; E > 100 GeV) data from the -ray binary system PSR B1259-63/LS 2883 taken around its periastron passage on 15th of December 2010 with the High Energy Stereoscopic System (H.E.S.S.) ...
  • Venter, Christo; Vorster, Michael Johannes; Büsching, Ingo; De Jager, Ocker Cornelis (IOP Publishing, 2011)
    Observations of the globular clusters (GCs) NGC 6388 and M15 were carried out by the High Energy Stereoscopic System array of Cherenkov telescopes for a live time of 27.2 and 15.2 hr, respectively. No gamma-ray signal is ...

    For hydrogen to become a serious contender for replacing fossil fuels, the manufacturing thereof has to be further investigated. One such process, the membrane based Hybrid Sulfur (HyS) process, where hydrogen is produced ...
  • Bouwman, Hindrik; Viljoen, Ignatius M.; Quinn, Laura P.; Polder, Anuschka (ELSEVIER, 2013)
    We investigated the presence, levels, relationships, and risks of HCHs, DDTs, chlordanes, mirex, PCBs, and brominated flame retardants (BFRs) in terrestrial and aquatic bird eggs from an area in South Africa where DDT is ...
  • McHugh, K.J.; Smit, N.J.; Van Vuren, J.H.J.; Van Dyk, J.C. (Taylor & Francis, 2013)
    A histology-based fish health assessment protocol was used in 2009–2010 to assess the health status of Clarias gariepinus from Pongolapoort Dam, South Africa. Nineteen fish were collected by angling. The histology of liver, ...

  • Labuschagne, Louis E.; Xu, Quanhua (ELSEVIER, 2013)
    We formulate and establish a noncommutative version of the well known Helson–Szegö theorem about the angle between past and future for subdiagonal subalgebras. We then proceed to use this theorem to characterise the ...
  • Van Coller, Helga; Siebert, Frances; Siebert, Stefan J. (OASIS, 2013)
    Understanding relationships between large herbivores and plant species diversity in dynamic riparian zones is critical to biodiversity conservation. The Nkuhlu exclosures in the Kruger National Park (KNP) provided ...
  • Chigeza, Shingairai; Roos, Vera; Puren, Karen (Taylor & Francis, 2013)
    This study examined the sense of community of people with experience of forced removals in a South African setting. The participants were 200 – 108 men (54%) and 92 women (46%) between 18 and 61 years of age and selected ...
