  1. 1. Negotiating Social Membership : Immigrant Claims-Making Contesting Borders and Boundaries in Multi-Ethnic Europe

    Författare :Zenia Hellgren; Barbara Hobson; Fiona Williams; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Migration; Immigration; Social Membership; Claims-making; Contentious politics; Sociology; sociologi;

    Sammanfattning : The concept of social membership is the mainframe for this dissertation, which encompasses four independent articles that approach the boundaries of social membership from different perspectives. Empirically, the focus lies on mobilizing groups that demand an extension of rights and/or inclusion for documented and undocumented immigrants in two European immigration countries: Sweden and Spain.

  3. 2. Classical and Quantum Correlations in Microwave Frequency Combs

    Författare :Shan Williams Jolin; David B. Haviland; Pertti Hakonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; parametric amplifiers; multipartite entanglement; microwaves; frequency comb; Gaussian states; bichromatic pump; surface acoustic waves; IQ mixer; fully inseparable states; superconducting circuits; hybrid circuits; intermodulation; nonlinear resonators; Material and Nano Physics; Material- och nanofysik;

    Sammanfattning : Denna avhandling undersöker korrelationer i frekvensdomänen, av både klassiskt och kvantmekaniskt ursprung, i icke-linjära mikrovågskretsar. Syftet är att utveckla en kompakt metod för att generera kvantmekaniska korrelationer mellan harmoniska oscillatorer (s.k. LÄS MER

  4. 3. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications

    Författare :Jesper Ekström; Hans Adolfsson; Jonathan Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transition metals; catalysis; bioinorganic chemistry; hydrides; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. LÄS MER

  5. 4. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes

    Författare :Klas Källström; Pher Andersson; Per Arvidsson; Jonathan Williams; Uppsala universitet; []
    Nyckelord :Organic chemistry; Catalytic; Asymmetric; Reductions; Ketones; Alkenes; Transition metal; Complexes; Organisk kemi;

    Sammanfattning : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. LÄS MER

  7. 5. The Role of Chemokines in Mast Cell Migration

    Författare :Mikael Juremalm; Timothy J. Williams; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Mast cells; chemotaxis; calcium flux; chemokines and chemokine receptors; Patologi; Pathology; Patologi; Pathology; patologi;

    Sammanfattning : Mast cells are very potent multifunctional effector cells of the immune system normally distributed throughout connective tissues. An accumulation of mast cells has been described in several pathological conditions such as allergic- and autoimmune inflammations and in certain tumours. LÄS MER
