  1. 1. On the treatment of Achilles tendon rupture. A prospective, randomised study of the results after surgical and non-surgical treatment

    Författare :Michael Möller; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; rupture; score; prospective; randomised controlled trial; isokinetic; muscular endurance; magnetic resonance imaging; ultrasonography;

    Sammanfattning : Only two prospective, randomised studies have been published on the outcome after treatment for Achilles tendon rupture. The controversy regarding the optimal treatment continues. In the present study, 112 patients with acute Achilles tendon rupture were randomised and all of them were followed up for two years.

  3. 2. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

    Författare :Akira Yamauchi; KTH; []
    Nyckelord :Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

    Sammanfattning : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. LÄS MER

  4. 3. Knee joint laxity and kinematics after anterior cruciate ligament rupture : roentgen stereophotogrammetric and clinical evaluation before and after treatment

    Författare :Håkan Jonsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Kinematics; Anterior-posterior laxity; Surgery; Roentgen stereophotogrammetric analysis; Muscle strength; Functional tests;

    Sammanfattning : Rupture of the anterior cruciate ligament (ACL) increases anterior-posterior (AP) laxity. The treatment aims to reduce or teach the patient to control this instability. Altered kinematics due to absent ligament function may result in knee arthrosis. This study evaluated the clinical and functional results of reconstructive surgery. LÄS MER

  5. 4. Testing and Evaluation of Interfibre Joint Strength under Mixed-Mode Loading

    Författare :Mikael S. Magnusson; Sören Östlund; Lars Wågberg; Mikael Nygårds; Kristofer Gamstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interfibre joint; fibre-fibre bonding; paper strength;

    Sammanfattning : The failure properties of interfibre bonds are the key for the build-up of strength in fibrous materials such as paper and paperboard. In order to tailor the properties of such materials by chemical or mechanical treatments and to learn how such modifications influence the properties at a microscopic level, direct measurement of individual fibre--fibre crosses are typically performed.

  7. 5. Achilles tendon rupture: the evaluation and outcome of percutaneous and minimally invasive repair

    Författare :Michael R Carmont; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon rupture; percutaneous; minimally-invasive; outcome; Achilles tendon Total Rupture Score; Achilles Tendon Resting Angle; Heel-Rise Height;

    Sammanfattning : Acute Achilles tendon rupture is common and has increasing incidence. This is thought to be due to increasing activity and sports participation in middle age. Sustaining an Achilles tendon rupture means a long rehabilitation period and many patients do not achieve full recovery of strength and function. LÄS MER
