A method of experimental determination of the profiles of temperature and composition of a high-temperature gas stream

A method of determining the parameters of a high-temperature gas stream based on the phenomenon of removal of mass from a plate placed in the stream is discussed. The possibility of applying the method is shown on a particular example.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 38, No. 5, pp. 853–858, May, 1980.

Dynamics of the physicotechnical characteristics of a metal during impact strengthening of its surface

Based on the laws of conservation of energy and momentum, equations of the evolution of metal characteristics during impact strengthening of its surface have been deduced. The conditions of the optimal mode of treatment are determined and its effective time is estimated. The experimental data agree fairly well with the results of the equation solutions.     

Methods of electron microscopy of biological and abiogenic structures in artificial gas atmospheres

This paper reviews opportunities for using electron microscopy in various gas atmospheres for the analysis and morpho-physiological modification of biological structures. The approaches that allow varying the gaseous phase content, as well as temperature, humidity, and pressure, are considered. The applicability of both kinetic and dynamic approaches to the tissue and bioinorganic structure manipulations is pointed out. The possibility of simulation of the beam-induced formation and disintegration of abiogenetic molecular structures is also mentioned as a particular case of the electron beam influence and treatment of the precursor medium in an artificial atmosphere.
