  1. 21. Effects of cold and hand-arm vibration on the peripheral neurosensory and vascular system : an occupational perspective

    Författare :Daniel Carlsson; Jens Wahlström; Tohr Nilsson; Erik Nordh; Hans Pettersson; Tiina Ikäheimo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; paresthesia; sensation of cold; hand-arm vibration syndrome; quantitative sensory testing; cold sensitivity; cold; cold exposure; frostbite; Sweden; cold injury; military; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background In Swedish working life, exposure to cold and exposure to hand-arm vibration (HAV) are two common health hazards. Health effects of HAV in the neurosensory, vascular and musculoskeletal systems are collectively denoted hand-arm vibration syndrome (HAVS), and have been thoroughly studied. LÄS MER

  2. 22. Effects of vibration on muscles in the neck and upper limbs : with focus on occupational terrain vehicle drivers

    Författare :Charlotte Åström; Gunnevi Sundelin; Lage Burström; Stefan Karlsson; Karin Harms-Ringdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Introduction: Occupational drivers of terrain vehicles are exposed to several risk factors associated with musculoskeletal symptoms in the lower back as well as in the neck and upper limbs. Vibration has been suggested to be a main risk factor. These drivers are exposed to both whole-body vibration (WBV) and hand-arm vibration (HAV). LÄS MER

  3. 23. Hand-arm vibration and working women : Consequences and affecting factors

    Författare :Sonya H Bylund; Lage Burström; Anders Knutsson; Eva Vingård; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; HAV; vibration; women; injuries; power absorption; handle; gender; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : The use of hand-held vibrating tools may lead to hand-arm vibration syndrome (HAVS), a condition with vascular, neurological and musculoskeletal symptoms. Vibrating tools are used in several occupations in which women can be found, e.g. by metal- and wood workers, drivers, and dental personnel. LÄS MER

  4. 24. Wind and atmospheric stability characteristics over the Baltic Sea

    Författare :Nina Svensson; Erik Sahlée; Hans Bergström; Anna Rutgersson; Xiaoli Guo Larsén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal transition; stable conditions; boundary layer rolls; low level jet; WRF; Baltic Sea; Meteorology; Meteorologi;

    Sammanfattning : In recent years there has been an increase in offshore wind energy, which poses the need for accurate wind speed estimates in the marine environment, especially in coastal areas where most wind turbines will be placed. This thesis is focused on the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction play an important role in explaining the wind patterns. LÄS MER

  5. 25. Environmental Monitoring by Multi-Spectral Lidar Techniques

    Författare :Petter Weibring; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-linear optics; fluorescence spectroscopy; scattering; multi-spectral imaging; Atom- och molekylärfysik; atmospheric pollution; Atomic and molecular physics; laser; remote sensing; lidar; DIAL; Fysicumarkivet A:2002:Weibring;

    Sammanfattning : Multi-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been applied. LÄS MER
