  1. 1. Configurational and Magnetic Interactions in Multicomponent Systems

    Författare :Björn Alling; Igor A. Abrikosov; Lars Hultman; Stefan Blügel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic interactions; Configurational thermodynamics; Curie temperature; theoretical physics; magnetism; TiAlN; TiN; AlN; CrN; TiCrN; nitrides; NiMnSb; NiCuMnSb; Heusler alloys; spintronics; half-metallic; spinodal decomposition; first-principles; ab-initio; Magnetism; Magnetism;

    Sammanfattning : This thesis is a theoretical study of configurational and magnetic interactions in multicomponent solids. These interactions are the projections onto the configurational and magnetic degrees of freedom of the underlying electronic quantum mechanical system, and can be used to model, explain and predict the properties of materials.

  3. 2. Hollow Cathode Deposition of Thin Films

    Författare :Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
    Nyckelord :Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

    Sammanfattning : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. LÄS MER

  4. 3. Development and tribological characterisation of magnetron sputtered TiB2 and Cr/CrN coatings

    Författare :Mattias Berger; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; TiB2; Tribology; Magnetron Sputtering; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : The aim of this thesis was to develop wear resistant physical vapour deposited coatings of TiB2 as well as multilayers of Cr/CrN. The correlation between deposition parameters and fundamental coating properties such as microstructure, composition, residual stress and hardness has been investigated. LÄS MER

  5. 4. The registered nurse as a clinical research nurse

    Författare :Beatrice Backman Lönn; Senada Hajdarevic; Åsa Hörnsten; Johan Styrke; Niclas Olofsson; Eva Brink; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical research nurses; ethical challenges; interviews; nursing; professional role; questionnaire; transition;

    Sammanfattning : Background: Clinical research studies are important for the developmentof new treatments in healthcare. The quality of clinical research relies on the competence, skills, and knowledge of the research team. LÄS MER

  7. 5. Inflammatory bowel disease, colorectal neoplasia and treatment with ursodeoxycholic acid in primary sclerosing cholangitis

    Författare :Lina Lindström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :inflammatory bowel disease;

    Sammanfattning : Background: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease closely associated with inflammatory bowel disease. PSC is progressive and ultimately leads to death or need for liver transplantation. Patients are also at high risk of developing colorectal neoplasia (CRN). LÄS MER
