  1. 1. Transverse anisotropy in softwoods Modelling and experiments

    University dissertation from Stockholm : KTH

    Author : Carl S. Modén; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. READ MORE

  2. 2. Simulation of individual cells in flow

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lailai Zhu; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic interaction; swimming microorganisms; capsule; Stokes flow; finite element method; boundary integral method; general geometry Ewald method; spectral element method; viscoelastic fluid; cellular deformation; flow cytometry; cell sorting; microrheology; Teknisk mekanik; Engineering Mechanics;

    Abstract : In this thesis, simulations are performed to study the motion ofindividual cells in flow, focusing on the hydrodynamics of actively swimming cells likethe self-propelling microorganisms, and of passively advected objects like the red bloodcells. In particular, we develop numerical tools to address the locomotion ofmicroswimmers in viscoelastic fluids and complex geometries, as well as the motion ofdeformable capsules in micro-fluidic flows.

  3. 3. A numerical and experimental study of initial defibration of wood

    University dissertation from Structural Mechanics, Lund University

    Author : Stefan Holmberg; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element simulations; fracture; deformation; fibre; defibration; wood; Building construction; Byggnadsteknik;

    Abstract : A major drawback of the defibration or refining process in manufacturing pulp is that of its large energy requirements. If the mechanics of the process were better understood, large amounts of energy could probably be saved. The initial defibration seems to be crucial for both the quality of the pulp and the total consumption of energy. READ MORE

  4. 4. Nonlinear micromechanics of open-cell cellular solids

    University dissertation from Structural Mechanics, Lund University

    Author : Per Hård af Segerstad; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FEM; Finite strains; Foams; Micropolar theory; Constitutive modelling;

    Abstract : An approach for modelling the response of open-cell cellular solids at finite strainsis developed. The model framework comprises a mechanistic formulation wherethe cellular solid is considered as a network of struts, each connecting two vertexpoints. READ MORE

  5. 5. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Virginia Claudio; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Abstract : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.
