As-built surface morphology and texture of Additively Manufactured (AM) metal parts reduce their mechanical corrosion properties. One chemically accelerated vibratory finishing (CAVF) technique employs a chemically-based stepwise process to gradually remove roughness without the need for significant manual manipulation. While this procedure is effective at producing smooth surfaces, response re...

Hard coatings are widely used in several industries to improve the service life of engineering components. W/WC deposited through chemical vapour deposition (CVD) have capability providing required protection on parts with complex geometries, commonly high wear and corrosive environments. Despite improvement life, a key important factor is adherence low roughness tolerance specifications, neces...

vibratory drilling (vd)process is a new modern technology where longitudinal wave with high frequency (more than 16 khz) and low amplitude (usually between 2 up to 30 µm) is superimposed on the movement of cutting tool, resulting in connection and disconnection of cutting tool engagement with workpiece. in this study, in order to perform vibratory drilling process, two vibration tools are desig...

Complex signals are common throughout the animal kingdom, consisting of one or more signals in one or more sensory modalities presented within a single display. I tested an efficacy-based backup hypothesis of complex signal function using the bimodal courtship signaling wolf spider Schizocosa uetzi. This hypothesis predicts that the visual and vibratory courtship displays function as backups to...

The current study compared the vibratory sensations at different sites, using a retrospective database of 547 Japanese diabetic patients. The vibratory sensation was assessed with a 128-Hz tuning fork at the medial malleolus, the great toe and the fifth toe. The vibratory sensations at different sites were significantly associated with one another (all P < 0.01). The vibratory sensation at one ...

Many coastal and offshore construction activities require the driving of piles into the seabed, either using impact or vibratory pile drivers. Impact pile driving produces an intense impulsive underwater noise that has been associated with fish deaths at very short range, whereas vibratory pile driving produces a lower level continuous noise. Because of the high sound levels involved, noise fro...

Objective. To investigate the influence of in vitro vibratory stimulation of human tonsillar mononuclear cells (TMCs). Methods. Fourteen IgA nephropathy (IgAN) patients with chronic tonsillitis (CT) and 12 CT patients with no renal pathology were enrolled. Group A TMCs were collected after 24 hours of culture and used to determine baseline levels. TMCs in groups B, C, D, E, and F were exposed t...
