  1. 1. Exploring the Railway System from a Risk Governance Perspective

    Författare :Alexander Cedergren; Lunds universitets centrum för riskanalys och riskhantering (LUCRAM); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; risk governance; railway; framing; accident investigation; implementation; vulnerability; resilience; critical infrastructure;

    Sammanfattning : In recent decades, the Swedish railway system has faced substantial deregulations. As a result, management of risk is often carried out in settings involving multiple stakeholders having various roles, mandates, and viewpoints on risk, and where no single stakeholder has the superior authority.

  3. 3. Modelling of compaction of metal powder and damage accum ulation due to fatigue in powder materials

    Författare :Joakim Cedergren; Mekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulik; vakuumteknik; vibrationer; akustik; Maskinteknik; hydraulics; Mechanical engineering; friction; FEM; numerical modelling; continuum mechanics; fatigue loading; powder compaction; vacuum technology; vibration and acoustic engineering;

    Sammanfattning : This thesis addresses powder manufactured (P/M) components, with special attention to the compaction process and to the sensitivity to damage accumulation due to fatigue within powder compacted specimens. Three dimensional simulations of the compaction process have been performed, using an explicit dynamic dilatant finite strain finite element code supplemented with the effects from contact friction within the die, modelled by Coulomb friction.

  5. 5. 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
