    Sammanfattning : The birth of microsystems set the ground for technologies never imagined before, for it is not only the small size what characterizes the miniaturized systems, but unique phenomena arise in the micro scale. This thesis relates to one such unique phenomenon, inertial focusing, a phenomenon that occurs in microfluidic systems if very special conditions are met and that allows for fine manipulation of particles in fluid samples.

  3. 2. The loss of a child to cancer : focusing on siblings

    Författare :Alexandra Eilegård Wallin; Karolinska Institutet; Karolinska Institutet; Sweden Stockholm Sweden; Sophiahemmet University College Stockholm Karolinska Institutet Childhood Cancer Research Unit Clinical Cancer Epidemiology The Departments of Oncology and Pathology and Women’s and Children’s Health; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Aims The overall aim of this thesis was to investigate the long-term psychological health consequences in bereaved families of children who have died from cancer, with a focus on the siblings. Further, we investigated if health-care and family related stressors might affect the long-term psychological health in bereaved siblings. LÄS MER

  4. 3. Essays on economic behavior, focusing and auctions

    Författare :Jim Ingebretsen Carlson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attention; focusing; experiments; auctions; shill bidding; approximated preferences; partnership formation;

    Sammanfattning : This thesis contributes to research on experimental and behavioral economics as well as auction theory. It consists of five papers.The first paper, Differences Attract: An Experimental Study of Focusing in Economic Choice, studies whether individuals' decisions are affected by focus effects. LÄS MER

  5. 4. On focusing of shock waves

    Författare :Veronica Eliasson; Nicholas Apazidis; John Dear; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; converging shock; Euler equations; imploding shock; Mach reflection; regular reflection; shock focusing; shock tube; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Both experimental and numerical investigations of converging shock waves have been performed. In the experiments, a shock tube was used to create and study converging shock waves of various geometrical shapes. Two methods were used to create polygonally shaped shocks. LÄS MER

  7. 5. On focusing of strong shock waves

    Författare :Veronica Eliasson; Nicholas Apazidis; Nils-Erik Molin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shock focusing; imploding shock; converging shock; reflected shock; annular shock tube; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Focusing of strong shock waves in a gas-filled thin test section with various forms of the reflector boundary is investigated. The test section is mounted at the end of the horizontal co-axial shock tube. Two different methods to produce shock waves of various forms are implemented. LÄS MER
