  1. 1. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Författare :Anders Kullingsjö; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER

  2. 2. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology

    Sammanfattning : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

  3. 3. On the engineering of proteins: methods and applications for carbohydrate-active enzymes

    Författare :Fredrika Gullfot; Harry Brumer; Antoni Planas; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; enzyme engineering; rational design; directed evolution; DNA shuffling; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; carbohydrate binding module; polysaccharide synthesis; Bioengineering; Bioteknik;

    Sammanfattning : This thesis presents the application of different protein engineering methods on enzymes and non-catalytic proteins that act upon xyloglucans. Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glucans in the cell wall of plants. LÄS MER

  4. 4. Wood Nanotechnologies for Transparency, Fire Retardancy and Liquid Separation

    Författare :Qiliang Fu; Lars Berglund; Hiroyuki Yano; KTH; []
    Nyckelord :Teknisk materialvetenskap; Materials Science and Engineering; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In this thesis, wood nanotechnologies for transparent, fire-retardant and hydrophobic/lipophilic wood have been developed. There are two main parts; wood template preparation/processing concepts and materials design using these templates.In the wood template processing part, highly porous nanostructured wood templates are prepared.

  5. 5. Fundamental Aspects on the Re-use of Wood Based Fibres : Porous Structure of Fibres and Ink Detachment

    Författare :Jennie Forsström; Lars Wågberg; Krrister Holmberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : In this work, different aspects on the re-use of wood based fibres have been studied, focusing on ink detachment of flexographic ink from model cellulose surfaces and changes in porous structure of kraft fibres following different treatments. New model systems for evaluation of ink detachment and ink-cellulose interactions were used. LÄS MER
