  1. 11. High-Pressure Microfluidics

    Författare :Sam Ogden; Klas Hjort; Greger Thornell; Wouter van der Wijngaart; Uppsala universitet; []
    Nyckelord :phase change; actuator; valve; pump; supercritical fluid; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : In this thesis, some fundamentals and possible applications of high-pressure microfluidics have been explored. Furthermore, handling fluids at high pressures has been addressed, specifically by creating and characterizing strong microvalves and pumps.A variety of microstructuring techniques was used to realize these microfluidic devices, e.g. LÄS MER

  3. 12. Phase change with stress effects and flow

    Författare :Amer Malik; Gustav Amberg; Long-Qing Chen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Martensitic transformation; phase-field method; polycrystal; stress-effects; microactuator; finite-element simulations.;

    Sammanfattning : In this thesis two kinds of phase change i.e., solid state phase transformation in steels and solid-to-liquid phase transformation in paraffin, have been modeled and numerically simulated. LÄS MER

  4. 13. Miniature Phase-Transistion Actuators

    Författare :Lena Klintberg; Lars Montelius; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Clearly, there is a need for simple, strong actuators capable of large strokes in miniaturized systems such as valves and optical shutters.The basis for this work is the microstructure technology with processing techniques adopted from the integrated circuit industry. LÄS MER

  5. 14. Quantitative immunochemistry in tissue sections : With special reference to urinary bladder carcinoma

    Författare :Kenneth Wester; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Urinary bladder carcinoma; immunohistochemistry; quantification; image analysis; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Urinary bladder carcinoma affects about 2 000 people in Sweden every year. It is a heterogeneous disease and for adequate treatment decisions, prognostic tools are needed. Many of these are based on immunohistochemistry (MC) and hampered by poorly reproducible methodologies and subjective evaluations. LÄS MER

  7. 15. Studies on the alpha-recoil implantation of 214Pb and 210Pb in glass surfaces,Implications for retrospective radon measurements

    Författare :Birgitta Roos; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unattached activity; attached activity; retrospective radon measurement; long-lived radon progenies; short-lived radon progenies; deposition velocity; implantation; 222Rn; glass surface; etching; simulation; Nuclear physics; Kärnfysik;

    Sammanfattning : Glass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. LÄS MER
