  1. 1. Wood Hemicelluloses - Fundamental Insights on Biological and Technical Properties

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Jennie Berglund; KTH.; [2018]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; hemicellulose; wood; glucomannan; xylan; structure; acetylation; flexibility; solubility; interaction with cellulose; stability.; hemicellulosa; trä; glukomannan; xylan; struktur; acetylering; flexibilitet; löslighet; interaktion med cellulosa; stabilitet.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Hemicelluloses are a group of heterogeneous polysaccharides representing around 30 % of wood where the dominating types are xylans, glucomannans and xyloglucans. Hemicelluloses complex molecular structure makes it difficult to understand the relationship between structure and properties entirely, and their biological role is not yet fully verified. READ MORE

  2. 2. Structure-aided design of antiviral drugs : Application of the method on HIV-1 protease and SIV reverse transcriptase

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Many efforts have been made to control the AIDS epidemic. Extensive studies have been done on the biology, biochemistry, and structural biology of HIV in the search for antiviral drugs. The viral-encoded enzymes reverse transcriptase and protease have been main targets for drug design. READ MORE

  5. 5. Stiffness modification of tensegrity structures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Seif Dalilsafaei; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensegrity; boom; finite element analysis; genetic algorithm; flexibility analysis; active structure; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Although the concept of tensegrity structures was invented in the beginning of the twentieth century, the applications of these structures are limited, partially due to their low stiffness. The stiffness of tensegrities comes from topology, configuration, pre-stress and initial axial element stiffnesses. READ MORE
