The Health & Safety Executive seeks control of risks from occupational exposure to hand-arm and whole-body vibration in Great Britain through law implementing a range of EU Directives but, in particular, the Physical Agents (Vibration) Directive 2002/44/EC and the Machinery Directive 98/37/EC....
Vibration control device, vibration control method, exposure apparatus, and device manufacturing method Vibration control system suppresses vibration of the structure is vibrated. Supported the structure, suppressing the vibration damping device (22), vibration control device, the second large amplitude than...
to or jumping from cab – Non-occupational causes – WBV, especially shocks & jolts Exposure action and limit values for whole-body vibration • Exposure Action Value (EAV): 0.5 m/s2 A(8) – many vehicle/mobile machinery users will need to consider WBV, but actions will often be simple...
It provides an overview of the evaluation, prevention and control of exposure to noise at the workplace, with a view to protecting workers against the risk of noise-induced hearing loss. Contents include: fundamentals of acoustics; anatomy and physiology of the ear and hearing; ear pathologies;...
[114]. Furthermore, exposure to female pheromones, which enhances male sex drive, is sufficient to counteract sleep rebound in mechanically sleep-deprived male flies. Thus, sex drive inhibits male sleep through a mechanism independent of the homeostatic control of sleep. Similarly, it has been ...
To check this hypothesis the frequency-dependent effect (2, 4, 6, 8, 10 Hz) of both MV (8 mm displacement) and EMF (0.4 mT intensity) on the bacterial cell proliferation were studied in both cases where the microbes were in the culture media during the exposure and when culture media ...
Environmental conditions include vibration, heat and cold, and other factors such as lighting and housekeeping. Altering these conditions can help eliminate or reduce injury risks. Q3.1 Vibration. To eliminate or reduce exposure to vibration:
Project cases of vibration control engineering practice for the multistory and tall building structure are introduced. Case 1 is a high-rise office building in high intensity zone with the seismic fortification...
The Smart PCS shall be installed in a sheltered place to avoid exposure to direct sunlight or adverse weather conditions (such as snow, rain, and lightning). The Smart PCS provides self-protection in high-temperature environments. If the Smart PCS is installed in a place subject to direct su...
Related to Automatic volume control:Automatic gain control,AGC circuit automatic gain control n (Electronics) control of a radio receiver in which the gain varies inversely with the magnitude of the input, thus maintaining the output at an approximately constant level. Abbreviation:AGC ...
