  1. 1. Airborne occupational exposures and risk of developing rheumatoid arthritis

    Författare :Anna Ilar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Rheumatoid Arthritis (RA) is an autoimmune, inflammatory disease with multifaceted aetiology. Cigarette smoke is the strongest environmental risk factor of RA, and research suggests that airborne exposures may trigger RA among genetically susceptible individuals. LÄS MER

  3. 2. A method for supporting implementation of semi-automated manufacturing cells : production modelling and parallel process development

    Författare :Torbjörn Ilar; Luleå tekniska universitet; []

  4. 3. Production simulation as a management tool

    Författare :Torbjörn Ilar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis focuses on process simulation and modelling in the context of production engineering. The thesis is presented in the form of seven papers which range in content from the holistic analysis of the application of modelling (papers 1-5) to a detailed examination of some of the areas of weaknesses in commercially available software (papers 6 and 7).

  5. 4. Interaction mechanisms for a laser-induced metallic boiling front

    Författare :Ramiz Saeed Matti Samarjy; Alexander F.H. Kaplan; Torbjörn Ilar; Michael Schmidt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser remote fusion cutting; Boiling front; High speed imaging; Additive manufacturing; Ejection; Absorption; Wavy surface; Deposition; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis is about fundamental interaction mechanisms of laser remote fusion cutting, RFC, which is based on the formation of a quasi-stationary laser-induced boiling front that causes drop ejection, preferably downwards. Laser cutting of metals, invented in 1967, has developed from a niche to a well established high quality cutting technique in the manufacturing industry. LÄS MER

  7. 5. JIA (juvenile idiopathic arthritis) in the Nordic countries. Aspects of classification, epidemiology and pain assessment

    Författare :Lillemor Berntson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arthritis; juvenile; rheumatoid; juvenile chronic arthritis; classification; heredity epidemiology; incidence; pain assessment; rating scales; VAS; ordinal data;

    Sammanfattning : Different classification criteria for chronic arthritis in childhood have been used in different parts of the world, which has made comparison between studies difficult. In 1995, a new set of classification criteria was proposed by the ILAR (International League of Associations for Rheumatism) to overcome such difficulties and to create more homogenous subgroups.
