Adaptations to High Hydrostatic Pressure

Annual Review of Physiology, 1992
The importance of adaptation to high pressure has long been implicit in the findings of studies in which 1 atm-adapted species were subjected to elevated pressures. Recent comparative studies have shown that pressure sensitivities of enzymes, structural proteins, and membrane-based systems differ markedly between shallow- and deep-living species. These

Hydrostatic Pressure Effect on Dislocations

Physica Status Solidi (a), 1972
Nonlinear effects are reported of hydrostatic pressure on dislocations in the framework of the square-law approximation in the derivatives of dislocation displacement. The pressure effect on the interaction of two dislocations, the interaction of a dislocation with a low-angle boundary, and the crystal boundary is considered.

Hydrostatic Pressure

2011
If you're going to understand how to think about pressures within the circulatory system, though, you'll need to know a few of the not-so-obvious principles of hydrostatics. Hydrostatic pressure is affected only by the density of the fluid, its vertical height above or below a measurement point, and the acceleration due to gravity.

THE REDUCTION OF INTUSSUSCEPTION BY HYDROSTATIC PRESSURE

Pediatrics, 1960
THE ARTICLE by Robins and Plenk which appears in this issue of Pediatrics is representative of the experience on the operative and non-operative forms of treatment of intussusception in childhood which is being reported by many others. Although the series is too small to draw any valid conclusions, the authors have attempted to show that reduction by ...

Hydrostatic pressurization of magnetite

Geophysics, 1969
Abstract Study of the effect of mechanical deformation on magnetic minerals indicates the structure-sensitive character of a parameter such as coercive force. Magnetoelastic effects and stress-induced rearrangement of the magnetic domain pattern lead to changes in magnetic remanence.

Pressure scales and hydrostaticity

High Pressure Research, 2007
Pressure scales are intimately related to the stress conditions of the actual experiments performed at high pressures. In the present article, I describe the effect of non-hydrostaticity on the pressure standard, comparing two X-ray data sets of gold taken with a He-pressure medium.

Dissociation of yeast hexokinase by hydrostatic pressure

Biochemistry, 1988
The pressure-induced dissociation of the isozymes P1 and P2 of hexokinase was investigated by studies of the spectral shift of the intrinsic protein fluorescence and by the fluorescence polarization of dansyl conjugates. The free energy of association of the monomers at atmospheric pressure, Katm, was -14.2 kcal mol-1 at 20 degrees C and -11.4 kcal mol-

Hydrostatic Pressure Apparatus

1969
This chapter is concerned with apparatus which can be used for determining physical parameters up to pressures normally reached in truly hydrostatic conditions, the upper limit being approximately 30 kb at room temperature. Apparatus for pressures greater than 30 kb will be considered in subsequent chapters.

An Apparatus for Helmstein's Hydrostatic Pressure Treatment

British Journal of Urology, 1976
Summary A new method of producing a balloon catheter for distension of the bladder is presented and an appropriate infusion set for the balloon is described. Various advantages and disadvantages have been discussed. I wish to express my sincere thanks to: Mr J. W.
