  1. 1. Experimental and computational investigation of the roll forming process

    Författare :Michael Lindgren; J Huetink; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.

  4. 3. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?

    Författare :Malin Lager; Anna J. Henningsson; Peter Wilhelmsson; Per-Eric Lindgren; Andreas Matussek; Fredrik Elgh; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Lyme borreliosis (LB) is caused by spirochetes within the Borrelia burgdorferi sensu lato complex and is the most common tick-transmitted disease in the northern hemisphere. The transmission of the spirochetes to humans in Europe is done by the Ixodes ricinus ticks, which can also transmit the relapsing fever species Borrelia miyamotoi. LÄS MER

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

    Författare :Lisa Labbé Sandelin; Björn Olsen; Jonas Waldenström; Per-Eric Lindgren; Ivar Tjernberg; Lars Hagberg; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Nonlinear materials for optical power limiting : characterization and modelling

    Författare :Hampus Lundén; Mikael Lindgren; Cesar Lopes; Bernd Eberle; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. LÄS MER
