  1. 1. Shoulder Kinematics and Impingement. Dynamic Radiostereometric analysis of the shoulder

    Författare :Erling Hallström; Göteborgs universitet; []
    Nyckelord :Shoulder kinematics; Radiostereometry; Impingement; Open surgery; Arthroscopic surgery; Physiotherapy; Clinical outcome;

    Sammanfattning : Abstract This study aimed to evaluate the three-dimensional kinematics of the shoulder joint in patients with shoulder impingement and controls with focus on three well known diagnostic tests; painful arc test (active abduction), Neer sign (passive elevation) and Hawkins sign. The shoulder rhythm, the speed of motion and if successful treatment of impingement could be associated with changes of the shoulder kinematics were studied Dynamic radiostereometry (RSA) is feasible method to study rotations and translations of the gleonohumeral joint because of its high precision.

  3. 2. Heat and Mass Transfer in Impingement Cooking. Aspects of Food Quality

    Författare :Urban Wählby; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cooking; impingement; meat; mass transfer; buns; food quality; heat transfer;

    Sammanfattning : Hot air impingement is a special form of forced convection, where the air is focused through the use of nozzles at a surface. In combination with rather high air velocities, a jet like phenomenon can evolve, which when used in for example cooking can achieve high heat transfer capacities. An Impingement oven prototype was constructed. LÄS MER

  4. 3. Femoroacetabular Impingement: The Pursuit of Evidence

    Författare :Olufemi R Ayeni; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Femoroacetabular impingement; evidence based medicine; hip; systematic review; survey;

    Sammanfattning : Femoroacetabular Impingement (FAI) is an important cause of hip pain in the young adult. It is the result of abnormal contact between the femoral head and neck junction and the acetabular rim. LÄS MER

  5. 4. The Supraspinatus Tendon : Clinical and histopathological aspects

    Författare :Bo Tillander; Rolf Norlin; Jon Karlsson; Linköpings universitet; []
    Nyckelord :supraspinatus tendon; Subacromial impingement; shoulder pain; impingement syndrome; corticosteroid injection; MEDICINE; MEDICIN;

    Sammanfattning : The supraspinatus tendon is an important structure of the rotator cuff. Subacromial impingement is a common reason for shoulder pain. Despite extensive scientific work in this field, the cause of impingement syndrome is still not fully understood. LÄS MER

  7. 5. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors

    Författare :Andreas Abdon; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; plasma; combustor; gas turbine; cooling; numerical simulations; turbulence; ribs; impingement; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER
