[Thickness of mouthguard sheet material after vacuum forming process depending on the thickness of mouthguard sheet].
PURPOSE Mouthguards are available to provide protection from stomatognathic injury during sports. The aim of this study was to examine the thickness of each part of mouthguard sheet depending on the thickness of mouthguard sheet material. METHODS Cross stripes (10 x 10 mm) were printed in mouthguard sheets. We measured the thickness of each cross stripe area using a measuring-device (R). Two ...
متن کاملMicroscopic high-speed liquid-metal jets in vacuum
The operation of microscopic high-speed liquid-metal jets in vacuum has been investigated. We show that such jets may be produced with good stability and collimation at higher speeds than previously demonstrated, provided that the nozzle design is appropriate and that cavitation-induced instabilities are avoided. The experiments with a medium-speed tin jet (u 60 m/ s, Re=1.8·10, Z=2.9·10 ) show...
متن کاملCavitation in a flowing liquid.
In this letter, I am going to propose that the cavitation threshold in a flowing liquid could be associated with the maximum tension that the fluid can sustain before undergoing cohesive fracture at a point. My criterion is not isotropic; I am thinking that a liquid will break if the tension in one direction exceeds a threshold, independent of the value of the other principal stresses. The othe...
متن کاملThickness of mouthguard sheets after vacuum-pressure formation: influence of mouthguard sheet material.
The aim of this study was to investigate the thickness of mouthguard sheet after vacuum-pressure formation based on the mouthguard sheet material. Three mouthguard sheet materials (4.0 mm thick) were compared: ethylene-vinyl acetate co-polymer (EVA), olefin co-polymer (OL), and polyolefin-polystyrene co-polymer (OS). The working model was made by hard gypsum that was trimmed to the height of 20...
متن کاملBreakup of Liquid Jets
For fundamental analysis of the transport of mass or heat in a dispersed system, accurate knowledge of behavior of jet is prerequisite. For generation of high interfacial area breaking of liquid jet in to small droplet is necessary. Liquid jet breakup is a complex phenomenon and dependent on many factors like velocity of jet, pressure difference, geometry of nozzle, temperature of both fluid, p...
