  1. 1. Studies on glycosides, especially the alpha/Beta transformation

  3. 2. Decay Properties and Hyperfine Interactions in Oriented Alpha-, Beta- and Gamma-emitting Nuclei

    Författare :Mats Lindroos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The hyperfine interaction has often been described as the bridge between atomic physics and nuclear physics. On the one hand it enables us to study important nuclear phenomena which only manifest themselves in the strong internal fields originating from the surrounding electrons and on the other hand it enables us to study properties of the atomic system or of condensed matter using nuclear probes.

  4. 3. From alpha to beta ocean: Exploring the role of surface buoyancy fluxes and seawater thermal expansion in setting the upper ocean stratification

    Författare :Romain Caneill; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean stratification; Thermal expansion coefficient; Buoyancy fluxes; Transition zone; Alpha – beta ocean;

    Sammanfattning : The ocean plays a central role in the climate system by absorbing excess anthropogenic heat and carbon dioxide. Moreover, the ocean circulation distributes heat from the tropics towards the poles. Due to the large ocean stratification, vertical exchanges between the ocean interior and the surface are limited.

  5. 4. Interferons in immunity to chlamydia pneumoniae

    Författare :Antonio Carlos Gigliotti (Tony) Rothfuchs; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Chlamydia pneumoniae; TLR; IFN-alpha beta; IFN-gamma; macrophages; T cells;

    Sammanfattning : The cytokine IFN-gamma is the architect behind an amazing immunological program of host resistance to intracellular bacterial and protozoan infections. IFN-gamma activates macrophages, making them into inhospitable habitats for parasites attempting to grow inside them. LÄS MER

  7. 5. Studies of the recognition and activation of natural killer cells

    Författare :Clas Une; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NK cells; activation; cytotoxicity; IFN-[gamma] IFN-[alpha] [beta]; IL-12; G-PI; MHC class I;

    Sammanfattning : Natural killer (NK) cells mediate part of the innate immune response that impedes the spread of invading microorganisms and shapes the downstream adaptive immune response. NK cells spontaneously kill tumor cells and other cells upon contact. Killing requires engagement of germline encoded receptors that mediate positive and negative signals. LÄS MER
