Ice-Water Phase Change Studies in Plastic and Non-Plastic Silts

A plastic phase of water from computer simulation.

We report a member of ices called plastic or rotator phase, in which individual water molecules make facile rotations as in liquid state but are held tightly in an ordered structure. Molecular dynamics simulations of three classical models of water show that a plastic ice phase appears at a temperature when ice VII is heated or liquid water is cooled at high pressures above several gigapascals....

Dislocation Mechanisms of Plastic Deformation of Ice

Characters and properties of dislocations in ice are thoroughly reviewed on the basis of the knowledge hitherto obtained by the X-ray topographic method as well as recently found dynamical behavior. Extremely low energy of the faults on the basal plane found by the method leads us to conclude that all of the dislocations in ice should be extended as wide as several tens to one hundred nano-mete...

Hypotension in Reconstructive and Plastic Surgery

to 60m.m.Hg. and with no ill effects at the end of the anaesthesia and the tremination of the operation the drops of the serum which contains 15mg. Wyamin will be in­creased to rise the blood pressure, now if the anaesthetic drug is Halothane recovery is quick and if Ether is used it is a little pro­longed. If while operating there is need for further injection of Adrenaline solution in the ope...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
