  1. 26. Development and characterization of sensitive, energy-independent solid-state photon dosemeters with high spatial and temporal resolution. Applications in clinical radiology and radiation protection

    Författare :Lars Herrnsdorf; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Si PIN; sensor; detector; dosemeter; CT; CBCT; dose profile; CTDP; R100; SiPM; Medipix; MCNP; AM; 4π detector; ACA; flex card micro assembly;

    Sammanfattning : AbstractModern medicine and health care rely on a variety of diagnostic and therapeutic equipment and methods that involve ionizing radiation. To guarantee quality and the safety of patients and staff, advanced radiation detectors and dosemeters are needed that have low energy and operate with directional independence for X-ray and γ-ray photons.

  3. 27. Motion analysis of the knee : kinematic artifacts, EMG normalisation and joint forces

    Författare :Daniel L Benoit; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Knee; tibiofemoral joint; kinematics; anterior cruciate ligament; ACL; bone pin; markers; neuromuscular adaptation; electromyography; normalisation; skin movement artifact; joint forces; ski injury; ski boot;

    Sammanfattning : The non-contact anterior cruciate ligament (ACL) injury is the most common and serious debilitating knee joint injury in male and female athletes. To create an ACL injury paradigm that will lead to improved treatment and prevention it is necessary to understand how ACL injuries occur. LÄS MER

  4. 28. Osteotomy for gonarthrosis - with special reference to the tibial callus distraction technique

    Författare :Göran Magyar; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; radiography; arthroplasty; complications; coating; hydroxyapatite; external fixator; femoral osteotomy; hemicallotasis; Knee osteoarthritis; tibial osteotomy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Osteotomy is used for correction of the altered load on the gonarthrotic knee joint. It can be performed above or below the knee. Clinical results depend on the correction after bone healing. LÄS MER

  5. 29. Machining and fatigue induced damage in bolted composite laminates

    Författare :Erik Persson; KTH; []
    Nyckelord :;

    Sammanfattning : The effects of hole machining defects on strength andfatigue life of carbon/epoxy laminates with open holes andpin-loaded holes subjected to static and fatigue loading havebeen investigated. Traditional drilling techniques causingvarying extent of damage and a novel method causing nodetectable damage were employed to machine the holes. LÄS MER

  7. 30. Experimental Study of Post-Dryout Heat Transferin Annuli with Flow Obstacles

    Författare :Ionut Gheorghe Anghel; Henryk Anglart; Michele Andreani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; annulus; post-dryout; temperature distribution; flow obstacles; new measurements; SRA - Energy; SRA - Energi;

    Sammanfattning : An experimental study on post dryout heat transfer regime in annuli with flow obstacles was conducted in the High-pressure Water Test (HWAT) loop at the Royal Institute of Technology in Stockholm, Sweden. An annulus consisting of two concentric heated pipes (12.7x24.3) mm, with total heated length equal to 3650 mm was employed as a test section. LÄS MER
