    • Zeta diversity as a concept and metric that unifies incidence-based biodiversity patterns 

      Hui, Cang; McGeoch, Melodie A. (The University of Chicago Press, 2014-11)
      Patterns in species incidence and compositional turnover are central to understanding what drives biodiversity. Here we propose zeta (ζ) diversity, the number of species shared by multiple assemblages, as a concept and ...

    • α-Diimine complexes of transition metals for the polymerisation of lower α-olefins 

      Fullaway, Phillip V. (Stellenbosch : University of Stellenbosch, 2005-12)
      In this study several potential polymerisation catalysts were synthesised. This was accomplished by coordinating α-diimine ligands such as N,N'-diferrocenyldiazabutadiene (DFDAB), N,N'-dimesityldiazabutadiene (DMDAB) as ...

    • The α-L-arabinofuranosidase of Aureobasidium pullulans 

      Matthew, Mark Kevin Alexander (Stellenbosch : Stellenbosch University, 2006-04)
      ENGLISH ABSTRACT: The euascomycetous fungus Aureobasidium pullulans produces xylanolytic accessory enzymes, including an α-L-arabinofuranosidase. The deduced amino acid sequence of the abfA gene encoding α-L-arabinofuranosidase ...
