  1. 16. Procedure for the reduction of the effect of transient whole body vibrations

    Författare :Peter Jönsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : There is a growing interest in the topic areas of increased vibration comfort and reduced vibration levels in work vehicles. Legislation, health costs and demands for increased competitiveness are all important motivating factors in this growing interest. LÄS MER

  3. 17. Effects of repetitive work on proprioception and of stretching on sensory mechanisms : implications for work-related neuromuscular disorders

    Författare :Martin Björklund; Håkan Johansson; Albert Crenshaw; Ronny Lorentzon; Måns Magnusson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Repetitive motions; Muscle fatigue; Proprioception; Muscle stretching; Work-related musculoskeletal disorders; Nociception; Ergonomics; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Sammanfattning : The aims of the thesis were (i) to investigate the impact of repetitive low-intensity work exposure on proprioception and (ii) to examine effects of muscle stretching (especially sensory effects and effects on muscle nociception) and to relate its application to the prevention, alleviation and/or treatment of work-related neuromuscular disorders. The effects of low-intensity repetitive work on the shoulder proprioception were tested in healthy subjects. LÄS MER

  4. 18. Cyclooxygenase-2 inhibitors and knee prosthesis surgery

    Författare :Andreas Meunier; Lars Good; Per Aspenberg; Tore Dalén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-steroidal anti-inflammatory agents; administration dosage; Arthroplasty; knee replacement; Surgical blood loss; Surgery; Cyclooxygenase inhibitors; Cyclooxygenase inhibitors; Fracture healing; Isoxazoles; Postoperative pain; Pyrazoles; Sulfonamides; Surgery; Kirurgi;

    Sammanfattning : Adverse effects of cyclooxygenase (COX) inhibitors on bone healing have previously been demonstrated in diaphyseal fracture models in animals. In spite of that, they are widely used as postoperative analgesics in orthopaedic surgery. After joint replacement, a bone repair process starts at the interface between bone and cement. LÄS MER

  5. 19. Streaming Video over Unreliable and Bandwidth Limited Networks

    Författare :Hussein Aziz; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streaming video; Mobile device; Frame splitting; Sub-frame crossing; Time Interleaving Robust Streaming; Region of Interest; Mean Opinion Score;

    Sammanfattning : The main objective of this thesis is to provide a smooth video playout on the mobile device over wireless networks. The parameters that specify the wireless channel include: bandwidth variation, frame losses, and outage time. LÄS MER

  7. 20. Wrist and thumb joint postures and motions: Measurements using electrogoniometry and EMG

    Författare :Per Jonsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER
