1. 1. Mellan massan och Marx : en studie av den politiska kampen inom fackföreningsrörelsen i Hofors 1917-1946

   Sammanfattning : The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union’s power were held by parties to the left of the social democrats. The overall aim is to problemize and discuss the issue of what characterised and made possible this deviation from the usual picture of a trade union movement dominated by social democracy. LÄS MER

3. 2. Polyelectrolyte multilayers of cationic and anionic starch and their use for improving the strength of papers made from mechanical pulps

   Författare :Lisa Lundström; Lars Wågberg; Mats Johansson; Per Engstrand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : Graphic paper is experiencing severe competition from other materials and, most of all, from other media. This means there is a great need to improve paper quality while reducing raw material and production costs. Polyelectrolyte multilayer (PEM) treatment (i.e. LÄS MER

4. 3. Meson Properties in Partially Quenched Effective Field Theory

   Författare :Niclas Danielsson; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

   Sammanfattning : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. LÄS MER

5. 4. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency

   Författare :Christer Sandberg; Per Engstrand; Jan-Erik Berg; Göran Bengtsson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. LÄS MER

7. 5. Dynamic soil-structure interaction of simply supported high-speed railway bridges

   Författare :Johan Lind Östlund; Jean-Marc Battini; Andreas Andersson; Mahir Ülker-Kaustell; Rui Calçada; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Railway bridge; Impedance function; Soil dynamics; High-speed train; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : Research performed on the subject of dynamic soil-structure interaction (SS) concerning railway bridges is presented in this thesis with the focus on simply supported railway bridges supported by shallow foundations in soil strata on bedrock. The research aims to obtain insight into the SSI of high-speed railway bridges and to provide recommendations on how to model the soil-bridge system from a design perspective. LÄS MER
