Since the electronic power conditioner (EPC) is a crucial part of space traveling-wave tube amplifier (STWTA), its reliability issue must be considered. The most effective way to prevent insulation breakdown potting. Silicone elastomers are commonly used as an encapsulant for EPC because their good physical and electrical properties. properties interfaces change under influence γ-radiation, whi...

Silicone fluids belong to the group of pseudoplastic non-Newtonian with complex rheological characteristics. They are considered in basic and applied researches a wide range industrial applications due their favorable physical thermal properties. One specific field automotive industry is working fluid viscous torsional vibration dampers. For numerical studies design development phase this dampi...

Dear Sir, I am Yong-Sun Ahn, from the Department of Ophthalmology of St. Vincent Hospital of Suwon, Kyungki-do, South Korea. Cataracts are a common problem in eyes with a glaucoma drainage device (GDD), because tube shunt surgery increases the incidence and progression of cataracts [1]. An Ahmed valve, the most commonly inserted GDD, is composed of a silicone tube connected to a flat plate sewn...
