  1. 6. Electron Transport and Chaos in Model Mesoscopic Systems

    Författare :Thomas Ouchterlony; Hongqi Xu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis mesoscopic structures intermediate in size between classical macroscopic objects and quantum mechanical objects as atoms are treated. The size of mesoscopic systems are of the same order as the wavelength of the electrons, which makes it necessary to take quantum mechanics into account. LÄS MER

  3. 7. Star-forming Dwarf Galaxies : Internal motions and evolution

    Författare :Thomas Marquart; Nils Bergvall; Janice Lee; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxy; Galaxies; Dynamics; Kinematics; Starburst; Dwarf Galaxies; Blue Compact Galaxies; Star Formation; Galaxy mergers; 3D-Spectroscopy; Spectroscopy; Astronomy; Astronomi;

    Sammanfattning : The study of dwarf galaxies is important in order to better understand the physics of the young universe and how larger galaxies form and evolve. In this work we focus on Blue Compact Galaxies (BCGs) which havemuch enhanced star formation (starbursts), causing blue colours and strong emission line spectra. LÄS MER

  4. 8. Diversity and focus of CMV specific T-cell responses in patients post-HSCT and with solid tumor

    Författare :Thomas Poiret; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human Cytomegalovirus (CMV) is a beta-herpesvirus that commonly infects humans. Most symptoms in healthy individuals are very mild. The virus is never eliminated and remains in the individual life-long. Thus, CMV and the immune response stay in coexistence until the protective response remains. LÄS MER

  5. 9. Maintenance performance indicators (MPIs) for railway infrastructure : identification and analysis for improvement

    Författare :Thomas Åhrén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : With increasing awareness that maintenance not only ensures safety and track performance, but also creates additional value in the business process; many infrastructure managers and owners are treating maintenance as an integral part of the business process. This is also true for the Banverket (Swedish National Rail Administration). LÄS MER

  7. 10. On atmospheric low frequency variability, teleconnections and link to jet variability

    Författare :Waheed Iqbal (وحید اقبال ); Abdel Hannachi; Peter Lundberg; Thomas Spengler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The atmosphere is a complex system with an infinite number of independent variables. The best approximations of the atmosphere are made using numerical models. The use of such models provides an invaluable tool for studying the atmospheric system. LÄS MER
