DESCRIPTION A 32-year-old scuba diver was admitted to the emergency department for distinct cutaneous lesions. Following an uneventful dive, his peers suspected of several lesions over his body pertaining to decompression sickness (DCS). After his initial assessment, he was referred to the underwater and hyperbaric medicine department for consultation. The patient was a senior diver and denied ...

ABSTRACT Two different sizes of aggregates glass microspheres were compared in suspension with silicone oils viscosities. The concentration the was kept constant and equal to 62 vv.%. rheological behavior suspensions evaluated by squeeze flow test, for two test speeds. For both particles size, when immersed less viscous oil, yield stress did not show a good correlation tests Meanwhile, more oil...

We consider squeeze film gas damping during microbeam motion away and toward a substrate as occurs during opening and closing of RF switches and other MEMS devices. The numerical solution of the gas damping problem in two-dimensional geometries is obtained based on the Boltzmann-ESBGK equation. The difference in damping force between downward and upward moving beams is shown to vary from as lit...
