MODERN DEVELOPMENTS IN THE FIELD OF SUPERTHIN CRUSHING OF FOOD FIBRES
DescriptionIn this work, we have analyzed the multiple literary sources and summarized the material regarding beet dietary fibers. Their composition, physicochemical, physicomechanical and hygrothermal properties were studied. The study of the particle-size distribution showed that the content of the insoluble fraction exceeded the content of the soluble fractions in all the samples. The use of the secondary products of processing of the plant raw material is also critical; they allow improving the preventive properties of products and enriching them with dietary fibers, protein, and mineral elements. The properties and quality of the raw material are, to the large extent, determined by and depend upon its granulometric composition, that is, upon the size of particles that compose this object. The authors determined the granulometric composition of the studied nutritional supplements. It was found out that the use of the combination of the impacts together with the abrading impact led to the intensification of the process, a decrease in the milling time and the uniformity of the obtained granulometric composition. The choice of the vertical mill as milling equipment in combination with the metal balls added to it to increase the efficiency of milling and uniformity of the granulometric composition of beetroot fibers was proved experimentally

Description
At the nodes of the various machines, we use plain bimetal bearings: a steel base - antifriction cladding layer. Bimetal bearings have increased performance. One of the ways of making such bearings is the way of centrifugal bimetallization with heating of the independent electric arc. An important requirement of this technology is a uniform heating of the workpiece along the entire length until the formation of a continuous layer of the molten cladding material. The process of bimetallization require temperature control, since within the movement of the electric arc, low heat or high heat are possible due to heat dissipation from the ends of the workpiece in the installation and from the outer surface of the workpiece to the environment. A viable option the temperature control of the heat process of bimetallization for industrial conditions is to control the temperature of the outer surface of the steel base. It is necessary to solve the heat problem of the relationship between the temperature on the surface of the workpiece with the temperature on the boundary layers. For this purpose the numerical solution of the mathematical model of the thermal process, which includes the heat transmitting equation of Fourier and heat transfer at the ends of the sleeve according to Newton's law. The equivalent coefficients of heat transfer are obtained based on calculated and experimental thermograms. This is a time-consuming work. To minimize the time of fixing the boundary value problem of the thermal process of bimetallization, in this work we present the preliminary modeling based on the analytical solution of the thermal task of bi-metallization

MONUMENTS OF THE FEBRUARY AND OCTOBER REVOLUTION IN THE TERRITORY OF RUSSIA
DescriptionThe article is devoted to the study of the monuments of revolutions of 1917 in Russia. It is emphasized that from the historical point of view, almost all monuments represent the embodiment of the losses and sufferings of humankind in various armed conflicts. This is especially true for the revolutions of 1917, which changed the entire modern history of the country, and even after 100 years cause a special interest both in the international scientific community and among ordinary people. This study specifies that after the final establishment and approval of the Soviet government, the new government realized that it was needed to create a certain basis, namely, its political symbolism as a foundation for the formation of image of the new government. The most important component of this process was the desire of the authorities to the formation of the ideas of the Soviet people about themselves and their place in the world, and, as a consequence, the folding of the foundations of Soviet patriotism, because the new generation who had no idea about the Russian Empire, began its life in the country, which had an ideology, but just started to develop the system of socialist values. The attention is paid to the fact that the monuments are one of the important elements of the historical and cultural heritage, which reflected the past experience of mankind, broadcast through architectural and sculptural symbols to the present, which contributes not only to the cultural enrichment of mankind, but also used by people to influence worldviews contemporaries. The article says that modern youth need to know the history of their country, not to forget about the numerous victims of various wars, to preserve peace and appreciate life

RESTORATION OF A MODEL OF A DYNAMIC NONLINEAR SYSTEM FROM THE TIME SERIES GENERATED BY IT
DescriptionThe main task in the analysis of time series is the reconstruction of the dynamical system that generated this series. To illustrate the nature of the behavior of a dynamic system described by a nonstationary time series, a «phase portrait» method is proposed. An acceptable description of the phase space of a dynamical system can be obtained if we take instead of real variables of the system delay vectors composed of the values of the series at consecutive moments of time. Restoration in a given class of a system of differential or difference equations is performed based on the scalar time series of the observed process. In order to eliminate the measurement error and accurately represent the position of the object in the current, future, or any of the past moments, it is proposed to apply the Kalman filter using the known mathematical model of object dynamics
