Rupture of esophagus by compressed air

open access: yesRevista Española de Enfermedades Digestivas, 2016
Currently, beverages containing compressed air such as cola and champagne are widely used in our daily life. Improper ways to unscrew the bottle, usually by teeth, could lead to an injury, even a rupture of the esophagus. This letter to editor describes a case of esophageal rupture caused by compressed air.

Energy Efficiency in Compressed Air Systems

open access: yes, 2010
Energy use in compressed air systems accounts for typically 10% of the total industrial electricity consumption. It also accounts for close to 99% of the CO2 footprint of an air compressor and approximately 80% of the life cycle costs of a compressor ...

Pattern matching of compressed terms and contexts and polynomial rewriting [PDF]

open access: yes, 2011
A generalization of the compressed string pattern match that applies to terms with variables is investigated: Given terms s and t compressed by singleton tree grammars, the task is to find an instance of s that occurs as a subterm in t. We show that this

PORTABLE COMPRESSED-AIR ATOMIZER. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1900
This apparatus consists of a tank 6 inches high and 4 inches in diameter. It has a brass barrel running through the center and closed at the lower end by a cone-shaped piece of rubber having a slit in its lower extremity. The piston which runs up and down in the barrel admits air through the rod by drawing it up and is prevented from escaping by a ...
