high-pressure gas
11high-pressure neurologic syndrome — a group of neurologic and neuropsychiatric signs and symptoms seen in deep sea divers below 100 meters, especially in those breathing heliox mixtures; symptoms vary, depending on the depth and gas mixture, and include tremor, incoordination,… …
12Gas blending — or gas mixing is the filling of diving cylinders with non air breathing gases such as nitrox, trimix and heliox. Hazards There are several hazards with gas mixing: * cylinders are being filled with high pressure gas. If there is any damage or… …
13High frequency ventilation — is a type of mechanical ventilation that employs very high respiratory rates (>60 breaths per minute) and very small tidal volumes (usually below anatomical dead space).cite journal |author=Krishnan JA, Brower RG |title=High frequency ventilation …
14Gas-operated reloading — Gas operation is a system of operation used to provide energy to operate autoloading firearms. In gas operation, a portion of high pressure gas from the cartridge being fired is used to power a mechanism to extract the spent case and chamber a… …
15Gas cluster ion beam — Gas Cluster Ion Beams (GCIB) is a new technology for nano scale modification of surfaces. It can smooth a wide variety of surface material types to within an angstrom of roughness without subsurface damage. It is also used to chemically alter… …
16Natural pressure gas lift operation — is natural gas production and injection into gas trunklines using natural formation energy at the initial stage of field development when the amount of formation pressure is high enough (5.5 to 12 MPa). For instance, natural pressure gas lift… …
17Gas leak detection — is the detection of gas leaks with apparatus like catalytic/infrared point sensors and IR open path sensors, more recent detection methods include Ultrasonic Gas Leak Detectors.In order to detect gas leaks with traditional methods, the gas itself …
18gas-turbine engine — Introduction any internal combustion engine employing a gas as the working fluid used to turn a turbine. The term also is conventionally used to describe a complete internal combustion engine consisting of at least a compressor, a… …
19Gas cylinder — For the mechanical devices used to impart a force from a pressurized liquid or gas, see pneumatic cylinder. For the large structures used to store town gas, see gas holder. Industrial compressed gas cylinders used for oxy fuel welding and cutting …
20Gas distribution network — is a system of external pipelines from a source to a gas consumer service line as well as facilities and engineering devices for them. An external pipeline is an underground, aboveground and/or overhead pipeline laid outside of the buildings to… …
