  1. 11. Atmosphere-ocean Interactions in Swell Dominated Wave Fields

    Författare :Alvaro Semedo; Anna Rutgersson; Oyvind Saetra; Piero Lionello; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Waves; Wind sea; Swell; Swell propagation; MABL; Air-sea interaction; Momentum flux; Wave climate; Coupling; Wave age; Empirical Orthogonal functions; Wave model; Climate model; WAM; RCA; wave heights; Meteorology; Meteorologi; Meteorologi; Meteorology;

    Sammanfattning : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. LÄS MER

  3. 12. On multilayered system dynamics and waves in anisotropic poroelastic media

    Författare :Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Wennhage Wennhage; Camille Perrot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poroelastic media; anisotropy; plane waves; multilayered systems; dynamics; acoustics; optimisation; matériaux poro-visco-élastique; anisotropie; ondes planes; panneaux multicouches; dynamique; acoustique; optimisation; Poroelastiska material; anisotropi; planvågor; flerskiktssystem; dynamik; akustik; optimering; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. LÄS MER

  4. 13. Beware of Non-Supportive Leaders : Moderating Effects of Supportive Leadership on the Risks and Effects of Workplace Bullying

    Författare :Stefan Blomberg; Michael Rosander; Bengt Ståhlbom; Duncan Lewis; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Workplace bullying; Supportive leadership; Health; Role ambiguity; Hostile work climate; Moderation; Longitudinal; Arbetsplatsmobbning; Stödjande ledarskap; Hälsa; Otydliga roller; Fientligt arbetsklimat; Moderation; Longitudinell;

    Sammanfattning : The aim was to investigate how supportive leadership affects workplace bullying—both in terms of risk factors that may lead to bullying but also in terms of the effects of bullying. The thesis includes three survey studies based on different Swedish cohorts and using different research design in terms of the number of data collection waves and timeframes. LÄS MER

  5. 14. Work and sleep - what's stress got to do with it?

    Författare :Johanna Garefelt; Loretta G. Platts; Hugo Westerlund; Göran Kecklund; Christian Benedict; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insomnia; job stress; retirement; social jetlag; accelerometery; Public Health Sciences; folkhälsovetenskap;

    Sammanfattning : Work may affect sleep by reducing the time available for recovery and, via work stress, by reducing sleep quality. Further, people experiencing sleep disturbance may be less resistant to work stress. These processes may lead to the development of a vicious cycle between work and sleep, in which stress has a central role. LÄS MER

  7. 15. Short-term effects of ambient temperature on daily deaths and hospital admissions

    Författare :Joacim Rocklöv; Bertil Forsberg; Jan Semenza; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; temperature; humidity; weather; climate; climate change; hot; heat; cold; cold spell; cold wave; heat wave; health; hospitalization; hospital admission; death; mortality; morbidity; epidemiology; environmental epidemiology; time series; Public health medicine research areas; Folkhälsomedicinska forskningsområden; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background: Incidence of death and hospitalizations have been observed to depend on short-term changes in weather and to increase with extreme temperatures. This thesis aims to strengthen the scientific knowledge on the relationship between temperature and daily deaths, but also the relationship between temperature and daily hospital admissions. LÄS MER
