Porosity of polypropylene samples was investigated by applying X-ray micro-computed tomography (micro-CT), which is getting more and popular as a non-destructive method. Microspheres were applied blowing agent at three concentrations: 3%, 6% 9% weight. Tensile testing specimens obtained injection molding technology its central, measuring part examined micro – CT. Results compared to porosity ca...

OBJECTIVE Phase-separation within HEMA-free all-in-one dental adhesives may result in the entrapment of droplets within the adhesive resin. Strongly air-blowing prior to polymerization, can remove most of these droplets. The objective of this study was to evaluate the effect these droplets may have on the resistance of the adhesive-tooth interface to NaOCl degradation. METHODS The micro-tensi...

BACKGROUND AND PURPOSE People with facial movement disorders are instructed to perform various facial movements as part of their physical therapy rehabilitation. A difference in the movement of the orbicularis oris muscle has been demonstrated among people without facial nerve impairments when instructed to "pucker your lips" and to "blow, as if blowing out a candle." The objective of this stud...

A computational study of a generic wing with a half span flap shows the mean flow effects of several blown flap configurations. The effort compares and contrasts the thin-layer, Reynolds averaged, Navier-Stokes solutions of a baseline wing-flap configuration with configurations that have blowing normal to the flap surface through small slits near the flap side edge. Vorticity contours reveal a ...
