21. Effects of cold and hand-arm vibration on the peripheral neurosensory and vascular system : an occupational perspective
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
22. Effects of vibration on muscles in the neck and upper limbs : with focus on occupational terrain vehicle drivers
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
23. Hand-arm vibration and working women : Consequences and affecting factors
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
24. Wind and atmospheric stability characteristics over the Baltic Sea
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
25. Environmental Monitoring by Multi-Spectral Lidar Techniques
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
