      Mouton, Marnel; Reeb, Desray; Botha, Alfred; Best, Peter (Wildlife Disease Association, 2009)
      A female southern right whale (Eubalaena australis) neonate was found stranded on the Western Cape coast of southern Africa. Skin samples were taken the same day from three different locations on the animal’s body 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 ...
