  1. 11. Massans röst : Upplopp och gatubråk i Stockholm 1719–1848

    Författare :Mats Berglund; Lars Nilsson; Maria Sjöberg; Börje Harnesk; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; riots; street violence; pre-industrial era; stagnation; Stockholm; political culture; democratisation; urban history; newspapers; Södermalm Riot; Ebel tumult; killing of Axel von Fersen; Crusenstolpe Riots; March Revolt; History; Historia; History; historia;

    Sammanfattning : The thesis examines riots and street violence in Stockholm between 1719 and 1848. By studying open conflicts, the thesis explores changes in societal power structures which otherwise are hidden. LÄS MER

  3. 12. Three essays on transport CBA uncertainty

    Författare :Peter Almström; Anders Karlström; Svante Berglund; Westin Lars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost-Benefit Analysis; Transport planning; Land-use planning;

    Sammanfattning : Cost Benefit Analysis (CBA) has for a long time been used in transport planning, but it is often questioned. One main argument against CBA is that the results depend largely on assumptions regarding one or a few input factors, as for example the future fuel price or valuation of CO2 emissions. LÄS MER

  4. 13. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface

    Författare :Mohd Farhan Ansari; Lars Berglund; Jean-Francois Gerard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; cellulose nanofibrils; hygromechanical properties; network structure; thermoset; polymer matrix composites; natural fiber composites; pulp fiber; strain hardening; humidity; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.

  5. 14. Crystalline cellulose in bulk and at interfaces as studied by atomistic computer simulations

    Författare :Malin Bergenstråhle; Lars Berglund; Stephen Eichhorn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose; molecular dynamics simulation; interfaces; Chemistry; Kemi;

    Sammanfattning : Cellulose is a linear polysaccharide, serving as reinforcement in plant cell walls.Understanding its structure and properties is of importance in the developmentof nanostructured cellulose materials. LÄS MER

  7. 15. Effects of Cell Wall Structure on Tensile Properties of Hardwood : Effect of down-regulation of lignin on mechanical performance of transgenic hybrid aspen. Effect of chemical degradation on mechanical performance of archaeological oak from the Vasa ship

    Författare :Ingela Bjurhager; Lars Berglund; Ulrike Wegst; KTH; []
    Nyckelord :tensile strength; transgenic hybrid aspen; lignin down-regulation; the Vasa ship; chemical degradation; longitudinell draghållfasthet; transgen hybridasp; ligninnedreglering; Vasaskeppet; kemisk nedbrytning; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Wood is a complex material and the mechanical properties are influencedby a number of structural parameters. The objective of this study has been toinvestigate the relationship between the structure and the mechanical propertiesof hardwood. Two levels were of special interest, viz. LÄS MER
