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...
We report a very rare case of successful intracardiac correction in patient with heterotaxy syndrome. The cardiac malformations included dextrocardia, double outlet right ventricle, pulmonary stenosis, interrupted inferior vena cava, hemiazygos continuation and total anomalous venous return. One-stage was performed. atrial procedure consisted intra- extraatrial rerouting the systemic hepatic ve...
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...
