The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines, soluble tumor necrosis factor recepto...

1. A variety of spontaneously active units was measured in the brain of the polyclad flatworm Freemania litoricola. Following application of MgCl2 there was both a decrease in number of active units and a decrease in frequency of firing of those cells which persisted in their activity. 2. Receptors which respond to vibration stimuli evoke potentials in the posterior part of the brain. Repetitiv...

There is only limited knowledge of the exposure to vibrations of ships' crews and their risk of vibration-induced health effects. Exposure to hand-arm vibrations from the use of vibrating tools at sea does not differ from that in the land-based trades. However, in contrast to most other work places, seafarers are also exposed to vibrations to the feet when standing on vibrating surfaces on boar...

In recent years there have been rapid advances in digital computers, the miniaturization of electronic circuits and the development of new materials. In the acoustics and vibration fields these advances have led to a continual increase in computational power and speed, improved acoustics and vibration transducers and instrumentation and better measurement techniques. In many cases the developme...

This thesis discusses the development of a heterodyne based system designed to detect the coherent component of light transmitted through a turbid medium. The system can detect coherent light intensity as low as 100 dB of an initial sub-milliwatt level input beam. It employs a very narrow bandwidth approach for generating the required heterodyne signal so that the bandwidth of the detection is ...

introduction vibrations include a wide range of engineering sciences and discuss from different aspects. one of the aspects is related to various types of engines vibrations, which are often used as power sources in agriculture. the created vibrations can cause lack of comfort and reduce effective work and have bad influence on the health and safety. one of the important parameters of the diese...

An improved approach to interferometry using sinusoidal phase shifting balances several harmonic components in the interference signal against each other. The resulting computationally efficient phase-estimation algorithms have low sensitivity to errors such as spurious intensity noise, vibration, and errors in the phase shift pattern. Specific example algorithms employing 8 and 12 camera frame...

We report coherent anti-Stokes Raman scattering correlation spectroscopy (CARS-CS) that measures the fluctuation of the CARS signal from scatterers in a subfemtoliter excitation volume. This method probes dynamical processes with chemical selectivity based on vibration spectroscopy. High-sensitivity CARS-CS measurements are carried out with epi-detection or polarization-sensitive detection. The...

We discuss the application of photoelectron angular distributions as a probe of time-evolving rovibrational wavepackets. A physical picture is drawn of the mechanism through which rotation–vibration coupling mechanisms are reflected in the time-dependent photoionisation asymmetry parameters. The effects of complicating features that may obscure the interpretation of time-resolved photoelectron ...

Introduction Current resuscitation guideline recommends that automated external defibrillator (AED) should never be placed in the analysis mode during transport because the movement of the vehicle can interfere with rhythm assessment. To date, no direct comparison of the AED performance at the scene and in a moving ambulance has been made. The aim of this study was to determine the intensity of...
