The Basic Law of Dynamics and The Mach Principle

The dependences of inertial and gravimetric masses from each other are derived taking into account the response of the Universe to interacting bodies. It was found that the inertial mass depends not only on the size of the corresponding gravitational mass, but also on the force acting on the body, and the relations of the inert and gravitational masses depend not only on the force acting on the body, but also on the gravitational mass of this body. However, if instead of the ratio of inert and gravitational masses we choose the difference of the inverse values ​​of these masses, the resulting formula turns out to be independent of the gravitational mass of the body. A formula for the basic law of dynamics is proposed taking into account the response of the Universe to interacting bodies in accordance with the Mach principle. It is shown that the error from the use of Newton’s second law without taking into account the response of the Universe to interacting bodies in many experiments can exceed the error caused by other factors

Influence of The Distribution of Gas Molecules by Temperature on The Rate of Gas-Forming Reactions

A method is proposed for calculating the temperature distribution of gas molecules depending on the gas temperature  . The method consists of determining the mean free path of molecules that characterizes the gas temperature, at which the maximum number of molecules with temperature , and then the desired distribution. The results show that at a given gas temperature, the total mass of molecules contains a large number of molecules whose temperatures are much different from the total gas temperature. From this, it follows that the ceramic technology of synthesis in principle does not allow us to obtain highly pure substances

Realization of Equilibrium Distributions of Molecules in Gases Boris Georgievich Golovkin

It is shown that all possible distributions of molecules of an ideal gas with zero dimensions of monatomic molecules that collide elastically with each other are in equilibrium, and with nonzero dimensions, a universal equilibrium distribution of the gas molecules along with the velocities and angular momentum must arise. In a real gas in an isolated system, due to dissipation, evolution goes simultaneously toward the universal distribution and toward the occurrence of an equal-velocity distribution, and also towards the degradation of the gas due to the decrease of the molecular velocities to zero values. In a non-isolated system, the real gas has a distribution close to the Maxwell distributio

Method of Determinining Radii and Enthalpies of The Formation of Poliatomic Ions

Based on the Born-Haber cycle, a method is proposed for determining the thermochemical radii and enthalpies of the formation of polyatomic ions. In order to be able to compare the values ​​of the enthalpies of the formation of ions and salts, a method is proposed for normalizing these values ​​by relating them not to one mole of a substance, but to an averaged gram atom. The method is approved on vanadium oxide compounds. The values ​​of 22 radii and enthalpies of the formation of polyatomic ions containing vanadium, the energies of the crystal lattices and the enthalpies of formation of  81 vanadate are calculated. The obtained values ​​are compared with the experimental data

Phase chemistry in the Ca-Mn-Sb-O system at 1160-1250 °C

Phase equilibrium in the Ca-Mn-Sb-O system was studied in air at the temperature range from 1160 to 1250°C and a pseudo-quaternary phase diagram for the system CaO-MnO-Mn2O3-Sb2O5 is presented. The following compounds were discovered: new antimonate Ca 7Sb2O12 with a perovskite-like structure, solid solutions Mn2-xCaxSb2O7 (0 ≤ x ≤ 1.6) with a 3T-weberite structure, and Ca2-xMn xSb2O7 (0 ≤ x ≤ 0.23) with a 2O-weberite structure, as well as solid solutions Ca2Mn1+xSb 1-xO6 with monoclinic (0 ≤ x ≤ 0.67) and orthorhombic (0.75 ≤ x ≤ 1) perovskite structures. The existence of a number of double and ternary oxides and solid solutions on the basis of Sb 5+ and Mn2+, Mn3+, Mn4+ and with mixed manganese valence is confirmed.

MODERN FEATURES OF A LECTURE IN THE FORMAT OF DISTANCE LEARNING FOR STUDENTS OF A MEDICAL UNIVERSITY

Modern conditions of life specify appropriate requirements to the training of   medical specialists. Internet resources and on-line technologies become more popular in educational process.  The objective of the work is to analyze the role of lectures in the educational process of students of a medical university on the basis of literature data, as well as to determine the features of the distance learning process at the Department of Dermatovenereology and Cosmetology with the Course of Aesthetic Medicine of FPE of Zaporizhzhia State Medical University. By means of analysis of scientific and pedagogical approaches to lecturing format in different countries two points of view can be defined. The first one is the classic notion about forms and methods of lecturing. Such point of view is typical for majority of educational institutions all over the world. But there is another point of view which emphasizes the fact that the passive transfer of material to students significantly decreases the educational level of specialists and therefore the introduction of new forms and methods for training of medical specialists is required. A special place in the preparation of students of medical universities should take an online lecture-visualization and a lecture-conference. It was in this format that lectures were introduced during quarantine in connection with the COVID-19 pandemic at the Department of Dermatovenereology and Cosmetology with the Course of Aesthetic Medicine of FPE lectures were held using the MS Teams program based on Office 365 or Skype for business. During the lecture, the program provided for the possibility of interactive communication with groups of students or cadets. To control the effectiveness and perception of the information presented by the lecturer, an online questionnaire MS Forms on the topic of the lecture was used. The use of this software in lectures at the department helped to increase the level of cognitive processing of information, interest and motivation of all participants in the educational process.Key words: distance learning, online media lecture, education
