  1. 36. Improving detection and diagnosis of bearing failures in wind turbine drivetrains

    Författare :Daniel Strömbergsson; Pär Marklund; Kim Berglund; Ulf Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Wind power has in the last 20 years grown into one of the main sources of renewable energy in the world, with both the amount and size of the turbines increasing substantially. One of the major challenges for the wind power industry is the premature failures of especially the drivetrain components. LÄS MER

  3. 37. Neighborhood-level factors : barriers and assets to cardiovascular disease

    Författare :Naomi Kawakami; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aims: To examine whether the availability of goods, services, and resources differs by level of neighborhood deprivation (study I). To examine whether there are associations between neighborhood availability of potentially health-damaging (fast food restaurants and bars/pubs) and health-promoting (physical activity facilities and health care facilities) goods, services, and resources and CHD incidence (study II).

  4. 38. Advancing the measurement of sedentary behaviour : classifying posture and physical (in-)activity

    Författare :Roman Peter Kuster; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sedentary behaviour, defined by a sitting body posture with minimal-intensity physical activity, is an emergent public health topic. The time spent sedentary is associated with the incidence of non-communicable chronic diseases such as type 2 diabetes and cardiovascular disease and significantly shortens life-expectancy in a dose-response relationship.

  5. 39. Physical activity in Parkinson’s disease : measurement, correlates and effects of balance training

    Författare :Håkan Nero; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aim: The overall aim of this thesis was to investigate correlates of physical activity in older adults with Parkinson’s disease and to evaluate the effects, both short- and long term, of the HiBalance program on physical activity and sedentary. Further, to investigate the associated factors of a training effect on physical activity. LÄS MER

  7. 40. Physical activity and quality of life in women treated with Roux-en-Y gastric bypass surgery : a randomized controlled trial and qualitative interviews

    Författare :Sofie Possmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Bariatric surgery is the most effective method for weight loss and long-term weight loss maintenance, but requires several changes in health behaviors. In Sweden, Roux-en-Y Gastric Bypass (RYGB) is the most common bariatric surgery method, as it accounted for 49.3% of the bariatric procedures in 2018. LÄS MER
