  1. 1. Resonant Soft X-ray Spectroscopic Studies of C60 and Related Materials

    Författare :Tanel Käämbre; Arne Rosén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : This thesis addresses the electronic structure of molecular and correlated solids using resonant inelastic soft X-ray scattering (RIXS), non-resonant X-ray emission, photoemissionand X-ray absorption spectroscopies. The use of monochromatised synchrotron radiation and improved energy resolution for X-ray emission have made it possible to elucidate the normal state transport properties and to get further insight into the electron-vibration coupling in fullerenes and the related compounds.

  4. 3. Conformal Field Theory and D-branes

    Författare :Albrecht Wurtz; Jürgen Fuchs; Bert Schellekens; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; Conformal field theory; Vertex algebras; D-branes; Physics; Fysik; Physics; Fysik;

    Sammanfattning : The main topic of this doctoral thesis is D-branes in string theory, expressed in the language of conformal field theory. The purpose of string theory is to describe the elementary particles and the fundamental interactions of nature, including gravitation as a quantum theory. LÄS MER

  5. 4. Antibodies and Antibody Mimics in Binding Assays

    Författare :Ioana Wärnmark; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; ELISA; antibody; molecularly imprinted polymer; Biochemistry; Biokemi; Metabolism; metabolism; Biokemisk teknik; Polymer technology; Biochemical technology;

    Sammanfattning : This thesis presents development of new analytical methods using antibodies and molecularly imprinted polymers (MIPs) in binding assays: 1) The high specificity of antibodies and the wide variety of efficient labels make immunoassay one of the most popular analytical techniques today. Enzyme-linked immunosorbent assay (ELISA) is most widely used, since the enzyme label can be used as a catalyst to provide very high signal amplification. LÄS MER

  7. 5. Positron emission tomography in serotonergic drug development

    Författare :Bengt Andrée; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :PET; 5-HT1A receptors; 5-HT2A receptors; D2 dopamine receptors; antidepressive drugs; antipsychotic drugs; pindolol; NAD-299; S 16924; ORG 5222; M100907; WAY; DWAY;

    Sammanfattning : The serotonin neurotransmission system has a central role in drug treatment of depression and anxiety and is also discussed in relation to treatment of schizophrenia. The benefits of presently available drugs are however limited by partial of poor response and side effects. LÄS MER
