    Sammanfattning : The state-of-the-art tools for machining metals are primarily based on a metal-ceramic composite(WC-Co) coated with different combinations of carbide, nitride and oxide coatings. Combinations of these coating materials are optimized to withstand specific wear conditions. LÄS MER

  3. 22. TiC-based nanocomposite coatings as electrical contacts

    Författare :Jonas Lauridsen; Lars Hultman; Per Eklund; Hans Högberg; Michael Stüber; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This Thesis concerns the advanced surface engineering of novel TiC-based nanocomposite and AgI electrical contact materials. The objective is to make industrially applicable coatings that are electrically conductive and wear-resistant, and have a low coefficient of friction. LÄS MER

  4. 23. Fcγ-receptors in systemic autoimmune conditions : lessons from murine mercury-induced autoimmunity

    Författare :Klara Martinsson; Per Hultman; Karin Cederbrant; Johan Rönnelid; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In this thesis we investigated the role of activating (FcγRI, FcγRIII) and inhibitory (FcγRIIB) Fcγ-receptors on systemic autoimmunity using two mouse strains, DBA/1 (H-2q) and BALB/c mice (H-2d), susceptible to induction of autoimmunity by mercury (Hg).Fc-receptors for IgG (FcγR) link cellular and humoral immune responses, control the balance between activating and inhibitory immune responses and are important in the development of several autoimmune diseases.

  5. 24. Ledarskap i vardagsarbetet : en studie av högre chefer i statsförvaltningen

    Författare :Louise Moqvist; Glenn Hultman; Per-Erik Ellström; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Leadership; managers work; conceptions of leadership; executed leadership; Administrative procedure; Förvaltningsprocess;

    Sammanfattning : The study aim at describing and analysing the practices of and conditions for senior managers in public administration, as well as which similarities and differences are in existence both within and between authorities in this respect. The practices of senior managers are studied in the light of two dimensions, one explicit that comprises the values, ideologies, interests, knowledge and feelings that senior managers express, as well as an executed dimension that encompasses physical activities, what managers do, how the work is executed, where work is done and with whom they work.

  7. 25. Stage T1 Urinary Bladder Carcinoma : Investigation of A Population-Based Cohort

    Författare :Hans Olsson; Staffan Jahnson; Per Hultman; Peter Söderkvist; Sten Nilsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Approximately 2 300 new cases of urinary bladder carcinoma (UBC) are diagnosed every year in Sweden. This type of cancer is characterized as a long-standing disease with a high risk of recurrence and progression from an indolent to a more aggressive course. LÄS MER
