  1. 1. Weak Atomic Interactions

    Författare :Peter Schef; Sven Mannervik; Juliet C. Pickering; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metastable states; forbidden transitions; laser probing; hyperfine structure; LRDR; Atomic physics; Atomfysik;

    Sammanfattning : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. LÄS MER

  3. 2. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

    Författare :Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

  4. 3. Colour Reconnection and Weak Showers

    Författare :Jesper Roy Christiansen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Merging; Weak interactions; Parton Showers; Event generators; hadron collisions; Colour Reconnection; Fragmentation; Fysicumarkivet A:2015:Christiansen;

    Sammanfattning : This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. LÄS MER

  5. 4. Strategic Interactions among Swedish Local Governments

    Författare :Karin Edmark; Matz Dahlberg; Sören Blomquist; Jan Brueckner; Uppsala universitet; []
    Nyckelord :Economics; Strategic Interactions; Spatial Interactions; Tax Competition; Welfare Competition; Fiscal Federalism; Nationalekonomi;

    Sammanfattning : Essay 1 (with Matz Dahlberg) investigates if local governments react on the welfare benefit levels in neighbouring jurisdictions when setting their own benefit levels. The IV estimates indicate that there exists a "race-to-the-bottom" and that the effect is economically as well as statistically significant. LÄS MER

  7. 5. The solution conformations of macrocycles. Applications in the exploration of weak interactions and in drug development

    Författare :Emma Danelius; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macrocycles; cyclic peptides; NMR; solution conformational analysis; NAMFIS; β-hairpin; weak interactions; halogen bonding; protein-protein interaction; bioactive conformation; macrolides; cell permeable conformation.;

    Sammanfattning : Understanding the solution conformation and dynamics of molecules with biological relevance, as well as the impact of their conformation stabilizing weak interactions, is for example important for drug design. Macrocycles have attractive pharmaceutical properties, and are of special interest as drug leads for targets with large, flat and featureless binding sites like protein-protein interfaces. LÄS MER
