  4. 2. Luminescence properties of flexible conjugated dyes

    Author : Jonas Sjöqvist; Patrick Norman; Mikael Lindgren; Jacob Kongsted; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; force field; molecular dynamics; linear absorption; QM MM; absorption spectrum; emission spectrum; water solvation; stokes shift;

    Abstract : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. READ MORE

  5. 3. Modeling of Cold Pilgering of Stainless Steel Tubes

    Author : Yağız Azizoğlu; Lars-Erik Lindgren; Jonas Edberg; Per Gradin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; Hållfasthetslära; Solid Mechanics;

    Abstract : Cold pilgering is a complex forming process used to produce seamless tubes in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. READ MORE

  6. 4. Modeling and Simulation of Weld Hot Cracking

    Author : Joar Draxler; Lars-Erik Lindgren; Jonas Edberg; Paul Åkerström; Jesper Hattel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Several alloy systems are susceptible to weld hot cracking. Weld hot cracking occurs by fracture of liquid films, normally grain boundary liquid films, at the late stage of the solidification of the weld. The cracks can be small and therefore difficult to detect by nondestructive test methods. READ MORE

  7. 5. Neoehrlichia mikurensis in Sweden : An emerging tick-borne human pathogen

    Author : Lisa Labbé Sandelin; Björn Olsen; Jonas Waldenström; Per-Eric Lindgren; Ivar Tjernberg; Lars Hagberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neoehrlichia; Tick-borne Infections; Transfusion-transmitted infections; Bacterial Zoonotic infections; Blood Donors; Immunosuppression; Infectious Diseases; Emerging; Blood Safety; Bird Migration; Infektionssjukdomar; Infectious Diseases;

    Abstract : Neoehrlichia mikurensis is an emerging tick-borne human pathogen, causing neoehrlichiosis in immunosuppressed and immunocompetent individuals. It targets the vascular endothelium, leading to thromboembolic and vascular events, but can also pass without symptoms. READ MORE
