    Författare :Jan Lundberg; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Obliteration (gobbing) caused by water based lubricating fluids is studied experimentally by analyzing the flow through a small channel. Flow measurements, energy dispersive X-ray microscopy and photos show, that the rate of gobbing depends on which type of fluid that is being used. LÄS MER

  3. 3. Radical aspects on arthritis : the role of neutrophil generation of nitric oxide and superoxide in inflammatory conditions

    Författare :Jan Cedergren; Thomas Skogh; Tommy Sundqvist; Tony Forslund; Ingrid Lundberg; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; neutrophils; reactive oxygen species; arthritis; NOS; NO; arginase; integrins; Internal medicine; Invärtesmedicin;

    Sammanfattning : The polymorphonuclear neutrophil granulocytes (neutrophils) are gaining renewed interest regarding their involvement in chronic inflammatory disorders, including rheumatoid arthritis (RA). Besides phagocytic and destructive capabilities, neutrophils have regulatory roles, e.g. by influencing responses from dendritic cells and lymphocytes. LÄS MER

  5. 5. Geographical Proximity Effects and Regional Strategic Networks

    Författare :Heléne Lundberg; Martin Johanson; Jan-Åke Törnroos; Uppsala universitet; []
    Nyckelord :Business studies; Network; Regional development; Regional Strategic Networks; Företagsekonomi;

    Sammanfattning : This thesis focuses on regional strategic networks (RSNs). RSNs are used as a tool for regional development with a view to strengthening regional relationship-development and networking by forming regional groups of actors. The thesis aims to clarify the nature of RSNs and the value of geographical proximity in both theoretical and practical terms. LÄS MER
