  4. 3. Regulation of Mast Cell Survival

    Författare :Christine Möller; Gunnar Nilsson; Alf Grandien; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; A1; Bfl-1; Bim; Bcl-2 family members; basophil; SCF; forkhead; survival; Patologi; Pathology; Patologi;

    Sammanfattning : Mast cells are long-lived effector cells of importance for both acute and chronic inflammations. Mast cells can be activated in many different ways, leading to the release of inflammatory mediators. In contrast to most other inflammatory cells, activated mast cells have the capacity to recover, regranulate and thereby be activated again. LÄS MER

  5. 4. Self-employment Entry and Survival : Evidence from Sweden

    Författare :Jenny Nykvist; Henry Ohlsson; Eva Mörk; David Blanchflower; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-employment; entrepreneurship; liquidity constraints; wealth; displacement; plant closure; survival; success; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: Hurst and Lusardi (2004) use higher-order polynomials in wealth in estimating the relationship with entrepreneurship. They find evidence conflicting with the existence of extensive liquidity constraints in the United States. In this paper, their approach is replicated on Swedish data. LÄS MER

  7. 5. Survival Estimation for Opportunistic Maintenance

    Författare :Johan Svensson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-stationary renewal process; non-homogeneous Poisson process; survival; optimal maintenance; discretization; points of support; crack growth; discretization;

    Sammanfattning : The problem of rational maintenance of aircraft engines is studied with respect to the influence of random events. Aircraft engines can be more economically maintained and resources can be saved if the maintenance process is improved. LÄS MER
