  1. 11. Modelling and simulation of paper structure development

    University dissertation from Sundsvall : Department of Natural Sciences, Engineering and Mathematics, Mid Sweden University

    Author : Stefan Lindström; Mittuniversitetet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; Fibre; Paper; Fibre suspension; Paper structure; Simulation; Rheology; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Abstract :      A numerical tool has been developed for particle-level simulations of fibre suspension flows, particularly forming of the fibre network structure of paper sheets in the paper machine. The model considers inert fibres of various equilibrium shapes, and finite stiffness, interacting with each other through normal, frictional, and lubrication forces, and with the surrounding fluid medium through hydrodynamic forces.

  2. 12. Through-Drying of Tissue Paper - Experiments and Modelling

    University dissertation from Chemical Engineering, Lund University

    Author : Henrik Weineisen; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper drying; modelling; TAD; through-drying; through-air drying; tissue; paper;

    Abstract : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). READ MORE

  3. 13. Antimicrobial materials from cellulose using environmentally friendly techniques

    University dissertation from KTH Royal Institute of Technology

    Author : Anna Ottenhall; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

  4. 14. Paper meets web how the institution of news production works on paper and online

    University dissertation from Jönköping : Jönköping International Business School

    Author : Elena Raviola; Högskolan i Jönköping.; Högskolan i Jönköping.; [2010]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Other social sciences Media and communication studies; SAMHÄLLSVETENSKAP Övrig samhällsvetenskap Medie- och kommunikationsvetenskap; SOCIAL SCIENCES Business and economics Business studies; SAMHÄLLSVETENSKAP Ekonomi Företagsekonomi;

    Abstract : The dissertation investigates the institution of news production at work, on paper and online, through an ethnographic study at the largest Italian financial newspaper Il Sole-24 Ore. Building on institutional theory and taking inspiration from Bordieu’s theoretical apparatus describing how cultural capital works, the dissertation presents a framework for the way institutions work, a framework that echoes Mary Douglas’ How Institutions Think (1987).
