[Purpose] Sclerostin is mechanosensitive protein that is produced exclusively by osteocytes. It was reported that the plasma sclerostin level increases in the 10th minute after the application of Whole-Body Vibration. The aim of this study was to determine whether single extremity-vibration induces any change in the serum sclerostin level. [Subjects and Methods] Eight healthy young-adult volunt...

It might be assumed that increasing the thickness of a glove would reduce the vibration transmitted to the hand. Three material samples from an anti-vibration glove were stacked to produce three thicknesses: 6.4, 12.8 and 19.2 mm. The dynamic stiffnesses of all three thicknesses, the apparent mass at the palm and the finger and the transmission of vibration to the palm and finger were measured....

Traditionally, computer communication networks have been optimized with respect to throughput, robustness and absolute delay, with little or no concern for the variation in delay (jitter) induced by the network. It is now desirable that high speed networks support a greater range of telecommunication services by providing a multi-service environment. If the transmission of jitter-sensitive tra ...

A common argument against prostitution states that selling sex is harmful because it involves selling something deeply personal and emotional. More and more of us, however, believe that sexual encounters need not be deeply personal and emotional in order to be acceptable--we believe in the acceptability of casual sex. In this paper I argue that if casual sex is acceptable, then we have few or n...

The idea for this note arose during the “Web Information Retrieval and Linear Algebra Algorithms” held at Schloss Dagstuhl in February 2007. Many brilliant people working on either side (numerical analysis and web search) had a chance to meet and talk for one week about mathematical and practical aspects of linear methods for ranking, and in particular (not surprisingly) PageRank and HITS. Ther...

The spread of the cover sheet is a divisive phenomenon. Their appearance is geographically bound and their content situated in the local political and financial context. In this article we discuss the arguments for and against the coversheet in its guise as a fixture on institutional repository preprints, exploring the issue through statistical information gathered from survey material and from...

in this paper, the effects of transverse cracks on rotating shaft were studied. according to earlier works, crack shaft failure decrease the critical speed of the shaft and also exhibit a nonlinear vibration behaviour leading to increases the amplitude of 1x and 2x harmonics (first and second order of rotational speed in torsional vibration). this suggests that the application of order analysis...

foam injection is widely applied in amounts of fields to drilling, production, and formation protection. sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. therefore, it is necessary to seek ways for improving the performance of foam injection. an increased disturbance to the stratum, like the vibration caused by a seismic o...

In the various working field, vibration may cause injurious to human body. Especially, in case of the vibration which is constantly and repeatedly transferred to the human. That gives serious physical problem, so called, Reynaud phenomenon. In this paper, we propose a vibration transmissibility reduction module with flexure mechanism for personal tools. At first, we select a target personal too...

The vibration control of a construction vehicle must be carried out in order to meet the aims of sustainable environmental development and to avoid the potential human health hazards. In this paper, based on market feedback, the driver seat vibration of a type of wheel loader in the left and right direction, is found to be significant over a certain speed range. In order to find abnormal vibrat...
