1. 16. Paper meets web : how the institution of news production works on paper and online

   Författare :Elena Raviola; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; Medie- och kommunikationsvetenskap; Business studies; Företagsekonomi;

   Sammanfattning : 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).

3. 17. In-Plane Fracture of Paper

   Författare :Johan Tryding; Institutionen för byggvetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Paper; Fracture energy; Strain softening; Localized damage; Fracture mechanics;

   Sammanfattning : The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. LÄS MER

4. 18. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

   Författare :Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.

5. 19. Preparation of Electroconductive Paper by Deposition of Conducting Polymer

   Författare :Elson Montibon; Magnus Lestelius; Lars Järnström; Agne Swerin; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electroconductive paper; conducting polymer; adsorption; coating; organic solvents; bulk conductivity; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The thesis describes an investigation into the interaction between the conducting polymer and cellulosic materials, and the preparation of electroconductive paper. The adsorption behavior of the conducting polymer onto cellulosic materials was characterized. LÄS MER

7. 20. Whiteness and Fluorescence in Paper : Perception and Optical Modelling

   Författare :Ludovic Gustafsson Coppel; Per Edström; Håkan Olin; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paper Whiteness; Fluorescence Whitening Agents; Kubelka-Munk; light scattering; paper industry applications; Colour Appearance Models; CIECAM02; Monte Carlo; Optics; Optik;

   Sammanfattning : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This includes psycho-physical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.
