The study period was divided into two intervals from 1961 to 1975 and from 1976 to 2017. Since 1976, in all climatic zones of the Caucasus region, negative trends in average annual temperatures changed direction to positive ones. The strongest growth was observed in the summer season in all climatic zones. Changes in the seasonal and annual rainfall patterns are not so obvious: both an increase and a decrease in the amount of precipitation and daily maximums were observed. The paper presents a numerical assessment of the rate of degradation of glaciers in Terskol (high-mountainous zone) against the background of an increase in the rate of growth of summer temperatures in recent decades.

The authors carried out the extensive experimental and theoretical studies of creep deformation and its reversibility on prisms with various degrees of carbonization in order to determine the physicochemical nature of the creep of aerated concrete during carbonization. As a result, it was found that the main reason for the increase in creep and reduction of its reversibility for aerated concrete, taking into account its carbonization factor, is the fact that the content of the gel-like part of silica acid increases and the volume of the crystalline part of the solid phase changes. There is an increase in its absolute specific surface; microdamages in the structure of concrete are growing and they are associated with the conversion of hydrated calcium silicate to calcium carbonate.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

A diesel generator based on a TMZ-450D singlecylinder air-cooled engine and its are described. In this connection, a specific task of the work is the study of the wear of parts in the cylinder-piston group of a complete diesel engine. In the statement of such a problem, a number of fundamental questions were solved regarding the compatibility of additive packages with the basic composition of lubricating oil and the final cost of the antiwear product added to the lubricating oil. The work demonstrates the specificity of the preparation for the tests and the technology of their implementation. Additionally, the technology of measuring parts in the cylinder-piston group, i.e. pistons, piston rings and cylinder lining. The study demonstrates the results of tribological field tests of lubricants tested in diesel engine TMZ-450D. The engine has a single-cylinder vertical layout and is designed for installation on light-duty vehicles, small-sized equipment, drives for mobile power plants, and as a stationary auxiliary marine engine. The implementation of the studied antiwear lubricant additive allowed reducing the overall wear rate of the cylinder-piston group of the diesel engine by 5-7%.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.
