  1. 11. Quantum Chemical Studies of Enzymatic Reaction Mechanisms

    Författare :Bianca Manta; Fahmi Himo; Lubomir Rulisek; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; B3LYP; enzyme; cluster approach; mechanism; zinc; manganese; cytosine deaminase; ω-transaminase; dinitrogenase reductase-activating glycohydrolase; dual substrate recognition; organisk kemi; Organic Chemistry;

    Sammanfattning : Computer modeling of enzymes is a valuable complement to experiments. Quantum chemical studies of enzymatic reactions can provide a detailed description of the reaction mechanism and elucidate the roles of various residues in the active site. LÄS MER

  3. 12. Combustion characteristics of some alternative fuels in ICE: : a detailed numerical study

    Författare :Siyuan Hu; Strömningsteknik; []
    Nyckelord :Combustion; duel fuel; methane; hydrogen; nheptane; methanol; DNS; simulation; openFoam; mixture-averaged; RCCI; ignition wave;

    Sammanfattning : Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. LÄS MER

  4. 13. Information and control in financial markets

    Författare :Samuel Lee; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Market Liquidity, Active Investment, and Markets for Information. This paper studies a financial market in which investors choose among investment strategies that exploit information about different fundamentals. On the one hand, the presence of other informed investors generates illiquidity. LÄS MER

  5. 14. Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality

    Författare :Lucia M. Garozzo; Henrik Johansson; Chris White; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; double copy; gauge theory; string theory; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. LÄS MER

  7. 15. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    Författare :Deborah Rupert; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Sammanfattning : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.
