• 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 clustering in ²⁸Si probed through the identification of high-lying 0⁺ states 

      Adsley, P.; Jenkins, D. G.; Cseh, J.; Dimitriova, S. S.; Brummer, J. W.; Li, K. C. W.; Marin-Lambarri, D. J.; Lukyanov, K.; Kheswa, N. Y.; Neveling, R.; Papka, P.; Pellegri, L.; Pesudo, V.; Pool, L. C.; Riczu, G.; Smit, F. D.; Van Zyl, J. J.; Zemlyanaya, E. (American Physical Society, 2017)
      Background: Aspects of the nuclear structure of light α-conjugate nuclei have long been associated with nuclear clustering based on α particles and heavier α-conjugate systems such as ¹²C and ¹⁶O. Such structures are ...
    • 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 ...
