  1. 1. Women on sick leave for long-term musculoskeletal pain : Factors associated with work ability, well-being and return to work

    Författare :Mamunur Rashid; Annika Nilsson; Marja-Leena Kristofferzon; Marina Heiden; Katja Boersma; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopsychosocial model; musculoskeletal pain; postal survey; prognostic factors; return to work; sick leave; women of working age; work ability and well-being; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

    Sammanfattning : Background: Taking sick leave (SL) for long-term musculoskeletal pain (MSP), predominantly in the neck, shoulders and back, is common among women in Sweden. Long-term MSP affects their daily life and causes impaired work ability and long-term SL. LÄS MER

  4. 3. Cerebral Venous Thrombosis - Complications and Outcomes

    Författare :Erik Lindgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral venous thrombosis; complications; outcome; seizures; return to work; dural arteriovenous fistula; follow-up;

    Sammanfattning : Cerebral venous thrombosis (CVT) is a relatively rare cause of stroke, which predominantly affects working-aged adults and particularly women. The clinical course is highly miscellaneous. Data from large cohorts are scarce and knowledge on CVT complications and outcomes are limited. LÄS MER

  5. 4. On the Attachment of Lightning Flashes to Wind Turbines

    Författare :Mengni Long; Marley Becerra; Rajeev Thottappillil; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind turbines; upward lightning; lightning attachment of dart and dart-stepped leaders;

    Sammanfattning : The work presented in this thesis aims at investigating the attachment of lightning flashes to wind turbines. Modern wind turbines are highly exposed to lightning strikes, due to the increase of their height and the rotation of the blades. Upward lightning is the dominant mechanism of lightning strikes to them. LÄS MER

  7. 5. Electromagnetic Interference in Distributed Outdoor Electrical Systems, with an Emphasis on Lightning Interaction with Electrified Railway Network

    Författare :Nelson Theethayi; Rajeev Thottappillil; Farhad Rachidi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electromagnetic Compatibility EMC ; Lightning; Lightning Protection; Transmission Lines; Electromagnetic Wave Propagation; Underground Cables; Grounding; Electromagnetic Transients; Electromagnetic Interference; Shielding Effectiveness; Railway Systems; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis deals with the electromagnetic compatibility (EMC) problems of distributed electrical networks, especially that caused by lightning to electrified railway. Lightning transients were found to damage important devices that control train movements, causing traffic stoppage and delays. LÄS MER
