1. 6. Dialogkompetens i skolans vardag : En aktionsforskningsstudie i hörselklassmiljö

   Författare :Ann-Christine Wennergren; Sture Brändström; Karin Rönnerman; Anders Ågren; Gunilla Härnsten; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; hard-of-hearing pupils; dialogue competence; critical friends; school improvement; participatory action research; sociocultural theories; Music Education;

   Sammanfattning : In classes for hard-of-hearing pupils there are children and young people with different degrees of impaired hearing, all of whom need hearing aids and technical equipment inthe environment. The initial problem area of the present thesis concerned the pattern of communication in the classroom. LÄS MER

3. 7. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper

   Författare :Henrik Kjellgren; Gunnar Engström; Lars Järnström; Lennart Stolpe; Torbjörn Helle; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof paper; Barrier properties; Gas barrier; Paper properties; Coatings; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER

4. 8. Activation of dissolving pulps prior to viscose preparation

   Författare :Niklas Kvarnlöf; Ulf Germgård; Leif J. Jönsson; Carl-Axel Söderlund; Herbert Sixta; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolving pulp; enzyme; reactivity; viscose; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The conventional viscose manufacturing process is a mature process that needs to be improved with respect to its environmental impact and its production cost structure. Therefore a research study has been done with the aim to improve the reactivity of the dissolving pulp used, in order to reduce the chemical demand in the viscose process and thus reduce the cost and indirectly the environmental impact.

5. 9. Printability and Ink-Coating Interactions in Inkjet Printing

   Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER
