Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

An Investigation of Short Translator Linear Machines for Use in a Free Piston Engine

, 2019
In a free piston engine, the translator of a linear generator is coupled directly to the moving cylinder of a thermodynamic engine. For a linear machine to have a constant active area, either the translator or the stator must be oversized.
