  1. 21. Low Frequency Impact Sound in Timber Buildings : Transmission Measurements and Simulations

    Författare :Jörgen Olsson; Andreas Linderholt; Börje Nilsson; Carl Hopkins; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber floors; FE-simulations; Light weight floors; Frequency response functions; Building acoustics; Byggteknik; Civil engineering;

    Sammanfattning : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. LÄS MER

  3. 22. Does spinal alignment influence car occupant responses? -The influence of variation in whole spinal alignment patterns on vertebral kinematics under rear impact conditions-

    Författare :Fusako Sato Sakayachi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neck injury; rear impact; whiplash; occupant; female; cervical vertebral kinematics; MRI; Multi-Dimensional Scaling; automotive seated posture; spinal alignment;

    Sammanfattning : The susceptibility of women to Whiplash Associated Disorders (WADs) has been the focus of numerous epidemiologic studies. Summarising the epidemiologic WAD studies, women were found to be subject to up to three times higher risk of sustaining WADs than men. LÄS MER

  4. 23. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Författare :Riaz Bhanbhro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Sammanfattning : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. LÄS MER

  5. 24. Irritable bowel syndrome diagnosed in primary care : Occurrence, treatment and impact on everyday life

    Författare :Åshild Olsen Faresjö; Ingemar Åkerlind; Ewa Grodzinsky; Toomas Timpka; Gunnel Hensing; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irritable bowel syndrome IBS ; occurence; treatment; psychosocial factors; psychological factors; working conditions; gender; health-related qualtity of life HRQOL ; Social medicine; Socialmedicin;

    Sammanfattning : Background: IBS is the most common functional gastrointestinal disorders and affects approximately 10-20 % of the general population and is widespread in all societies and socio-economic groups. Although the disorder does not have a life-threatening course, it still seriously affects the patients in their everyday life. LÄS MER

  7. 25. Failure of thinwalled structures under impact loading

    Författare :Salar Mostofizadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thinwalled shell structures; cohesive zone; phantom node method; ductile failure; XFEM;

    Sammanfattning : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. LÄS MER
