The improvement of the technical equipment effectiveness is currently becoming particularly important. This applies not only to large and high-energy-intensive machines, but also to household appliances, the total energy consumption of which often exceeds the energy consumption of the overall equipment. These types of devices include, in particular, grinding and cutting equipment. The mathematical description of the processes carried out on this equipment is generalized and can be extended to a wider class of machines, including waste processing and mining equipment. The technological parameters, the design of screw grinders, and the processes of movement, deformation, extrusion and cutting carried out in them are characterized by a significant number of factors affecting the energy intensity. The main ones are the geometric parameters of the screw, machine’s body, cross knife, grinding plate’s thickness, the number and diameter of holes in it, as well as the product’s physical-mechanical characteristics and operating conditions. The most important for the mathematical description are the zones and processes where the main share of the consumed power is spent. The complexity of their analytical description is due to a simplified consideration of either individual technological zones of grinders’ existing designs, or the use of unreasonable simplifications.

“…Displacements of VAE are the major cause of inadmissible deformations of the foundations of structures in the regions with seasonally frozen grounds if those foundations were constructed without taking measures to exclude or reduce the deformation of foundations during springautumn periods. In this connection, we have conducted a research into the changes of stregnth and deformation properties of grounds in relation to the water content as these are the major parameters of sagging of the foundations of structures [8][9][10][11][12][13]. The research was aimed at the establishment of correlation dependency of the shear stregnthon the water content.…”

The paper considers the research into the work of vertical axial elements in seasonally frozen grounds under dymanic strain within the frameworks of annual cycle. The authors provide the results of laboratory research into the specific adhesion and dynamic strain impact. They also have developed a structure capable of reducing the impact from frost heaving anf dynamic impact forces during thaw period.

“…The world experience shows that more and more electric energy is required for the sustainable development of society in various directions every year. Especially it is required in industry, services and personal life [1][2][3][4][5][6][7]. It happens against the background of a decrease in stocks of various types of fuel and environmental degradation [7][8][9][10][11][12][13].…”

In a paper the method for remote monitoring of the radiation characteristics of the environment in the area of the nuclear power plant is considered. To solve this problem, the need to use remote methods of environmental monitoring is justified A method is proposed for determining radioactive formations in the atmosphere using a radar station. Using the methodology for determining radioactive formations in the atmosphere by changing the reflection coefficient of an electromagnetic wave from a given formation is justified. Calculation of changes in the reflection coefficient of an electromagnetic wave from a radioactive formation in the atmosphere for different climatic conditions is calculated. The results of studies of radioactive contamination in the atmosphere are presented. The advantages of the method developed by us in comparison with others are noted. The directions of scientific research to expand the functionality of the method developed by us are determined.
