  1. 1. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    Författare :Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. LÄS MER

  3. 2. Making waves : A study of the patterns and consequences of non-state actor participation in global fisheries governance

    Författare :Matilda Petersson; Henrik Österblom; Lisa Dellmuth; Robert Blasiak; Megan Bailey; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global fisheries governance; regional fisheries management organizations RFMOs ; non-state actors; non-governmental organizations NGOs ; transnational partnerships; participation; influence; effectiveness; process tracing; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : States have established regional fisheries management organizations (RFMOs) to manage transboundary fish stocks. However, the effectiveness of these bodies has been questioned. Problems with overfishing, illegal, unreported, and unregulated (IUU) fishing, and bycatch remain persistent and difficult to solve. LÄS MER

  4. 3. Multiscale methods for simulation of paper making

    Författare :Gustav Kettil; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paper making; Numerical upscaling; Lay down simulations; Virtual paper sheets; Fiber network model; Forming fabric flow; Fiber suspension flow; Fiber-fiber interaction; Multiscale methods; Fluid structure interaction;

    Sammanfattning : In this work, multiscale methods for simulation of paper making are developed. The emphasis is on simulation of the paper forming process and simulation of the mechanical properties of paper sheets. To simulate paper forming, a novel fiber-fiber interaction method is proposed.

  5. 4. Managing the fuzzy front end of product and process development : case studies of process firms

    Författare :Monika Kurkkio; Maria Elmqvist; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Redovisning och styrning; Accounting and Control;

    Sammanfattning : This thesis addresses different aspects of how to manage product development and process development. Two research studies have been conducted, both within the process industry. LÄS MER

  7. 5. Pappersarbete : Formandet av och föreställningar om kontorspapper som medium

    Författare :Charlie Järpvall; Mediehistoria; []
