The efficiency of the valved linear compressor is very important to space J-T throttling refrigerator. To compare single-piston (SVLC) and symmetrical dual-piston (SDVLC), this paper explores factors that affect efficiency. Firstly, analyzes mechanical vibration system compressor, result shows highest when external force (current) in phase with speed. Then numerical solutions current velocity a...

BACKGROUND Respimat(®) Soft Mist(™) Inhaler (SMI) is a hand-held device that generates an aerosol with a high, fine-particle fraction, enabling efficient lung deposition. The study objective was to assess inhalation success among children using Respimat SMI, and the requirement for assistance by the parent/caregiver and/or a valved holding chamber (VHC). METHODS This open-label study enrolled...
