To ensure safe coil embolization for cerebral aneurysms, it is important to investigate the contact force between a and an aneurysm wall. Therefore, in our previous study, we developed experimental system measuring biomodel. However, because model was made of silicone rubber, its physical properties, such as friction coefficient, differed from those aneurysms vivo. this using poly (vinyl alcoho...
a dissolved methane sensor based on silicone tube was designed, constructed and optimized.the silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.a continuous stream of helium (50 ml/min) was directed through the tubing, sweeping out the dissolved methane which diffused through the walls of the tubing from t...
STATEMENT OF PROBLEM The success of most non-implant-retained extraoral prostheses depends on retention derived from skin adhesives. Part 1 of this study found that Skin-Prep Protective Dressing improved the retentive properties of adhesives and that Secure(2) Medical Adhesive was stronger than Epithane-3. Part 2 investigates the application of a second layer of adhesive to the prosthesis, whic...
A test chamber was projected and built (according to ISO 16000-9 Standard) to simulate atmospheric conditions experienced by rubber infill (when applied in synthetic turf pitches) and measure accurately the airborne emissions of pollutants such as dusts and volatile organic compounds (VOC), as well as pollutants present in leachates. It should be pointed out that standard ISO 16000-9 is only co...
PURPOSE To report a case of early decomposition of retained heavy silicone oil droplets. CASE REPORT The single highly myopic eye of a 16-year-old boy with history of scleral buckling and buckle revision developed redetachment due to inferior retinal dialysis. The patient underwent pars plana vitrectomy and injection of heavy silicone oil. Early emulsification of the silicone oil was observed...
A 72-year-old man had exchange of a foldable silicone multifocal intraocular lens (IOL) by transection, removal, and monofocal IOL replacement. One month after the exchange, irreversible corneal edema developed and penetrating keratoplasty was performed. At the time of the corneal transplant, a small silicone fragment was discovered in and removed from the anterior chamber. Histologic evaluatio...
