Intraocular Gas Injection in the Pseudophakic Patient

American Journal of Ophthalmology, 1980
Two patients underwent vitrectomy with the use of intraocular gas. In one patient the cornea decompensated because of lens-cornea contact and in the second patient a surgical technique devised to protect the cornea from lens contact was used successfully.

Gas Injection for Underground Gas Storage (UGS)

2021
In this chapter, some of the key aspects of UGS as a sustainable energy supply infrastructure were reviewed. This type of gas injection is associated with the reuse of depleted oil and gas formations as a natural underground storage volumes with proved reservoir characteristics and cap rock integrity, as well as available surface facilities and wells ...

Gas Injectivity Logging

SPE Permian Basin Oil Recovery Conference, 1959
Permian Basin Oil Recovery Conference, 7–8 May, Midland, Texas Introduction Along with the rapid development and application of re-energizing techniques designed to recover a greater percentage of the oil in place than can be produced under primary recovery methods, tools and techniques have been ...

A Investigation of Fuzzy Control for Gas-injection Pressure in Gas-Assisted Injection Molding

2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007
A fuzzy control system has been developed for gas injection pressure precise control in gas-assisted injection molding. The control model was derived theoretically and its performance is improved. A fuzzy controller and its control algorithm are established.

Actively controlled transverse gas injection

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
In general the problem of feedback control for an unsteady fluid flow is nonlinear. Especially challenging is the control of mixing processes in a hot, potentially reactive environment. Because of the high temperatures present, realistic sensors can only operate mainly in cool regions, e.g., away from flames and hot exhaust regions. Consequently, there

Intravitreal Gas Injection

1989
Internal tamponade of the retina by means of intravitreal gas injection antedates the basics of retinal detachment repair established by Jules Gonin in the 1930s. The first use of intravitreal air injection in retinal detachment management was reported by Ohm in 1911.1 The following year Rohmer2 reported 8 cases of retinal detachment in which ...

Mechanism of Toxicity of Injected CS Gas

Nature, 1970
IN 1928 Corson and Stoughton1 prepared a number of benzylidene malononitriles, including 2-chlorobenzylidene malononitrile (CS). Although these authors were primarily concerned with the isolation and chemistry of the condensation products of malononitrile and various aldehydes, sternutatory and irritant properties on the part of some of the compounds ...

Cryogenic Cooling by Noncondensible-Gas Injection

Science, 1965
Temperature control of various cryogenic liquids in the range from their boiling points to near or below their freezing points has been achieved by injecting a noncondensing gas, helium. The process is more easily accomplished than the usual vapor-pumping technique and is applicable in the range from 15° to 300°K.

Injection of a gas equilibrated with a liquid into the gas chromatograph

Chromatographia, 1975
Applicability limits of the existing methods for the introduction of a gas equilibrated with a liquid into a gas chromatograph are discussed. A new device as well as the method of its application are described. This new device permits gas sampling from an equilibrium system without changing the concentration of the substance distributed between the two

Gas Injection In The Safah Field, Oman

Proceedings of Middle East Oil Show, 1995
Abstract The Safah field contains 640 million barrels of oil-in-place and 62 billion cubic feet of gas cap. The field is divided into East and West lobes. The East lobe is subdivided into Northeast and Southeast lobes based on PVT properties. The Northeast lobe contains saturated oil with gas cap and the Southeast lobe has undersaturated
