Abstract
The acoustic emission following the salt solution processes is investigated. It is educed that the acoustic emission parameters depend on the substance chemistry. It is stated that irrespective of the crystal purity degree with their dissolution the total count of signals increases logarithmically, and activity of the acoustic emission decreases exponentially. It is shown that the occluded gases liberation is a crucial element of the acoustic emission under the crystal dissolution.

Abstract
Some original modifications of the genetic algorithms for analyzing the stationary states of the chemical dynamic systems at the defined thermodynamic parameters, IC engines among others, are offered. The development feature is allocation of small and large equation parameters among the equations and their solutions. Along with the known neuronet methods, the development can be integrated in ‘Engine’ simulation system.

Abstract
The problem of buckling failure of the dynamic cutting system is considered. The retarded argument effect formed in the tool-to-workpiece cutting force dependencies on the elastic deformational displacement is mainly focused. Some buckling mechanisms are revealed. The stability zones within the variable parameters that characterize the retarded arguments are analyzed.

Abstract
A new for the classical scheduling theory approach to solving distribution problems is offered. The approach is based on the introduction of the concepts of distribution matrices, estimate criteria of their properties and a developed algorithm of their enhancing transformations. The method named ‘selective-permutational’, as it is based on the selection and permutation of the perspective column elements of the distribution matrices, is formulated. Several examples are given.

Abstract
Some probability-theoretical models of the metal removal and the formation of the surface coating condition under the loose-abrasive machining are improved. The centrifugal-rotatory treatment (CRT) in the loose abrasive environment is considered from reliability. The effect of the abrasive granules on the reliability of the CRT production process (PP) in the loose abrasive environment and the formation of the stable toroidal-helical flow is investigated comprehensively. The characteristics that influence on the quantitative assessment of the production process reliability are defined.

Abstract
The implementation of the environmental management, a new stage of development of the enterprise management, is considered. The major task of the environmental management is the balance of effective enterprise activities and environmental conditions. The ecology-oriented management is brought to the level of the national priorities in Russia, however, there are some problems that interfere with its effective implementation. These problems are the most pressing challenge for small business.
