    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry; Coalescence; Breakup; Multiphase Flow; Computational Fluid Dynamics; Planar laser induced fluorescence; Population Balance Modelling; Turbulence; High speed imaging technique; Mass Transfer; Refractive index matching;

    Sammanfattning : The thesis investigates the dynamics of fluid particles in turbulent flows, which plays an important role in the chemical, pharmaceutical, food and petroleum industries. Phenomenological studies, new mathematical models for the breakup phenomena, and development of a simulation method for chemical reactors constitute the main parts of this thesis. LÄS MER

  4. 3. Imaging studies of cell physiology with particular reference to Na,K-ATPase function

    Författare :Ronnie M Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Na; K-ATPase; PKA; PKC; ouabain; cell attachment; Ca2 ; RVD; fluorescence lifetime;

    Sammanfattning : The membrane protein Na,K-ATPase is well known for its critical function of transporting sodium out of the cell and potassium into the cell, thereby creating a fundamental electrochemical gradient upon which several other important cell functions are dependent. In the current study we have investigated novel aspects of Na,K-ATPase function in cell physiology. LÄS MER

  5. 4. Kind words, cruise missiles and everything in between : A neoclassical realist study of the use of power resources in U.S. policies towards Poland, Ukraine and Belarus 1989–2008

    Författare :Barbara Kunz; Jan Hallenberg; Hans E. Andersson; Ronnie Hjorth; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neoclassical realism; foreign policy; power; U.S. foreign policy; Central and Eastern Europe; Poland; Ukraine; Belarus; Political science; Statsvetenskap; Political Science; statsvetenskap;

    Sammanfattning : This study intends to explain why the United States led entirely different policies towards Poland, Ukraine and Belarus under circumstances where realist theory would predict otherwise. Realism being an “environment based theory”, it would indeed predict a state to lead highly similar foreign policies under identical conditions. LÄS MER
