  2. 1. Cell Behavior and the Role of Profilin

    Author : Yu Li; Roger Karlsson; Christophe Ampe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. READ MORE

  5. 3. Numerical approaches to droplet growth in atmospheric turbulence

    Author : Xiang-Yu Li; Axel Brandenburg; Gunilla Svensson; Luca Brandt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; turbulence; coagulation; condensation; rain formation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The bottleneck problem of cloud droplet growth is one of the most challenging problems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius. Turbulence-generated collision has been thought to be the mechanism to bridge the size gap, i.e. READ MORE

  6. 4. Droplet growth in atmospheric turbulence : A direct numerical simulation study

    Author : Xiang-Yu (李翔宇) Li; Gunilla Svensson; Axel Brandenburg; Wojciech Grabowski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cloud micro-physics; turbulence; inertial particles; DNS; condensation; collision; coalescence; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This Ph.D. thesis examines the challenging problem of how turbulence affects the growth of cloud droplets in warm clouds. Droplets grow by either condensation or collision. READ MORE

  7. 5. Essays on Environmental and Energy Economics

    Abstract : Essay I: In January, 2005, the EU launched the first international emissions trading system (EU ETS), aimed at reducing carbon emissions in a cost-effective way by means of a market-based instrument. In this paper, we use the treatment/control, before/after design of the natural experiment approach to investigate the treatment effect of the EU ETS on the profitability of a sample of Swedish energy firms in 2005 and 2006.
