  2. 6. Analysis of rail breaks and insulated joint deterioration

    Author : Johan Sandström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rail breaks; Heavy Haul; Insulated joints; Wheel flats; Railway mechanics; Material fatigue;

    Abstract : The thesis deals with fatigue related issues in the field of railway mechanics. In particular rail breaks and deterioration of insulating joints are investigated. The study is largely motivated by plans to increase allowed axle loads in Sweden. READ MORE

  4. 7. Enhanced Composite Joint Performance through Interlacement of Metal Inserts

    Author : Sahar Akbarpour; Stefan Hallström; Conor McCarthy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : The work in this thesis investigates bolted joints in fibre reinforced composites with particular focus on a novel insert concept. The concept is characterised by replacing all composite plies with stacked metal patches, locally around a bolt hole, so that they jointly form a solid metal reinforcement. READ MORE

  5. 8. Molecular and clinical studies of cartilage and bone macromolecules in arthritis

    Author : Bengt Månsson; Reumatologi och molekylär skelettbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skeleton; Prognosis; Tissue damage; Bone markers; Cartilage markers; Rheumatoid arthritis; Psoriatic arthritis; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

    Abstract : The pathogenesis of inflammatory arthritides include synovial inflammation and joint tissue destruction. Tissue destruction has traditionally been regarded a consequence of inflammation, but recent observations indicate that the processes are not always closely linked and may proceed uncoupled.

  6. 9. Finite Element Simulations of Biphasic Articular Cartilages With Localized Metal Implants

    Author : Krishnagoud Manda; Anders Eriksson; Ingrid Svensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; knee joint; metal implant; poroelastic; biphasic; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : Articular cartilage is a specialized connective soft tissue that resides onthe ends of long-bones, transfers the load smoothly between the bones in diarthrodialjoints by providing almost frictionless, wear resistant sliding surfacesduring joint articulation. Focal chondral or osteochondral defects in articularcartilage are common and show limited capacity for biological repair. READ MORE

  7. 10. B cell subpopulations in the pathogenesis of rheumatoid arthritis

    Author : Katrin Thorarinsdottir; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cells; Rheumatoid arthritis; Joint destruction; DAS28; CD21- low B cells;

    Abstract : B cell depleting therapy has proven to be an effective treatment in rheumatoid arthritis (RA), a disease characterized by the presence of autoantibodies against citrullinated proteins (ACPA) and the Fc portion of IgG (rheumatoid factor, RF). This demonstrates the vital role B cells play in the disease. READ MORE
