1. 1. Numerical modeling of pulsed volume discharges for the generation of ozone

   Författare :J. Olof Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modeling; ozone production; parameterstudy; pulsed discharge;

   Sammanfattning : The pulsed electric volume discharge is a new alternativefor the efficient generation of ozone in compact systems. Thisthesis presents a parameter study of the reactions in this kindof homogeneous discharge, using a here developed numericalmodel DISCHEM which solves plasma chemical kinetic rate andenergy equations.

3. 2. Industrial applications and properties of oxalate-degrading enzymes

   Författare :Sandra Winestrand; Leif J. Jönsson; Thomas Nilsson; Nils-Olof Nilvebrant; Gudmundur O. Hreggvidsson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxalic acid; oxalate oxidase; oxalate decarboxylase; calcium oxalate; scaling; active packaging; Kemi; Chemistry;

   Sammanfattning : Oxalate-degrading enzymes were investigated with focus on potential applications in the pulp and paper industry and in active packaging. Changes introduced to make the pulp and paper industry more environmentally friendly, such as recirculation of process-water streams and elementary chlorine free bleaching of pulp, have led to increasing problems with precipitation of calcium oxalate.
