Summary. Two main types of binary systems with distinctive solubility behavior under sub- and supercritical conditions were used to
subdivide ternary water-salt systems into three classes. Characteristic features of solubility behavior and phase equilibria
in ternary water-salt systems of each class at temperatures above 200°C are discussed on the basis of available experimental
data and some conclusions obtained as a result of theoretical derivation of fluid and complete phase diagrams.

The paper outlines an approach to identifying the principal dynamic-instability domain for systems composed of shells of revolution
with different shapes under axisymmetric periodic loading. The original problem is reduced to one-dimensional eigenvalue problems
with respect to the meridional coordinate. Results of calculations for a specific shell system are presented 相似文献

The three-dimensional structures of two enzyme-substrate complexes of SAICAR synthase from the yeast Saccharomyces cerevisiae with adenosinetriphosphate (ATP) prepared under different conditions were studied by X-ray diffraction analysis and then refined. An enzyme molecule was shown to contain two binding sites of ATP. One of these sites is located in the central cavity of the enzyme molecule and apparently binds the ATP molecule directly involved in the enzymatic reaction. In the complexes, the phosphate groups of ATP occupying this site adopt different conformations depending on the Mg2+ concentration. The functional role of the second binding site located at a distance of approximately 15 Å from the first site away from the central enzyme cavity has not been understood as yet. It might be that the second site perform the regulatory role in enzyme functioning. 相似文献

A method is proposed to solve the contact problem for laminated anisotropic shells of revolution. The method is based on a two-dimensional model that accounts for transverse shears and reduction. Also the method is based on the method of successive approximations, the generalized pseudo-force method, and a numerical-analytical method of solving boundary-value problems. The results obtained for a cylindrical shell of complex thickness structure are compared with those obtained in three-dimensional formulation__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 5, pp. 68–75, May 2005. 相似文献

Experimental studies of high-temperature phase equilibria in the BaCl2-NaCl-H2O made it possible to determine the conditions of heterogenization of homogeneous supercritical (SC) fluids spreading from
the BaCl2-H2O binary subsystem of type 2 and to reveal the continuity of the transformation of gasliquid equilibria into equilibria of
phase separation in SC environment. Comparison with the characteristics of the K2SO4-KCl-H2O system suggests that ternary systems with one volatile component formed by binary subsystems of type 2 with phase separation
and of type 1 without separation have the same type of phase diagrams. 相似文献
