  1. 16. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER

  3. 17. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

  4. 18. Experimental Investigation of Three-Dimensional Single and Double optical Lattices

    Författare :Harald Ellmann; Poul Jessen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A complete laser cooling setup was built, with focus on threedimensional near-resonant optical lattices for cesium. These consist of regularly ordered micropotentials, created by the interference of four laser beams. One key feature of optical lattices is an inherent ”Sisyphus cooling” process. LÄS MER

  5. 19. Three-dimensional mapping of fine structure in the solar atmosphere

    Författare :Vasco M. J. Henriques; Dan Kiselman; Göran Scharmer; Hector Socas-Navarro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sun; sunspots; Swedish 1-meter Solar Telescope; active regions; image processing; sunspot penumbra; Astronomy; astronomi;

    Sammanfattning : The effects on image formation through a tilted interference filter in a converging beam are investigated and an adequate compensation procedure is established. A method that compensates for small-scale seeing distortions is also developed with the aim of co-aligning non-simultaneous solar images from different passbands. LÄS MER
