Assessing social cognitive functions in elementary school children: or problems of motor activity disorders
The urgency of the research issue is due to the tendency of an increase in the number of children with disorders of the muscle-skeleton system and motor skills. In this regard, these children have problems in learning activities, relationships with peers and adults. The purpose of the research presented in the paper was to study the social and psychological peculiarities of the personality of elementary school children with motor activity (motor skills) disorder. To solve the tasks set in the study and test the hypothesis, a number of methods and techniques were used: theoretical analysis of scientific literature, empirical methods: observation, experiment, questionnaire, technique of N.I. Ozeretsky; children's version of S. Rosenzweig's test; "school-based anxiety” test. The study revealed that two options are possible in the development of the personality of elementary school children with motor activity disorders: favorable and unfavorable. An unfavorable variant of the child's personality development is associated with “non-constructive” behavior, which manifests in the inability to withstand difficult social situations. A favorable variant of personal development is characterized by the predominance of “constructive” behavior, which allows one to overcome life difficulties
Assessment of the quality of inclusive education in general education organizations of Russia
The purpose of this work was an empirical study of assessing the quality of inclusive education in the regions of the Russian Federation. The article presents the results of monitoring the quality of the implementation of inclusive education in general educational organizations of the regions of the Russian Federation. The criteria for a comprehensive assessment of the quality of inclusive education are highlighted. Discrepancies in assessments of the quality of individual parameters of inclusive education in the regions were revealed, ways of increasing its effectiveness were outlined
Fixed Volume Effect on Polar Properties and Phase Diagrams of Ferroelectric Semi-ellipsoidal Nanoparticles
For advanced applications in modern industry it is very important to reduce
the volume of ferroelectric nanoparticles without serious deterioration of
their polar properties. In many practically important cases fixed volume
(rather than fixed size) corresponds to realistic technological conditions of
nanoparticles fabrication. The letter is focused on the theoretical study of
the behavior of ferroelectric polarization, paramagnetoelectric coefficient and
phase diagrams of semi-ellipsoidal nanoparticles with fixed volume V. Our
approach combines the Landau-Ginzburg-Devonshire phenomenology, classical
electrostatics and elasticity theory. Our results show that the size effects of
the phase diagrams and polarization of semi-ellipsoidal BiFeO3 nanoparticles
nontrivially depends on V. These findings provide a path to optimize the polar
properties of nanoparticles by controlling their phase diagrams at a fixed
volume.Comment: 15 pages, 5 figures, we added the section IV. Paramagnetoelectric

Local Magnetohydrodynamic Characteristics of the Plasma Stream generated by MPC
This paper investigates the spatial distributions of electrical current which flows inside the plasma stream generated by a magnetoplasma compressor (MPC). Two different modes of MPC operation with different gas supply scenarios have been applied in the experiments presented here. The first is the operation mode with a pulse injection of xenon into the interelectrode space, and the second is the operation mode with residual helium in the chamber and local injection of xenon directly into the compression zone. The maximum value of the electric current observed outside the MPC channel is 15 ÷ 20% of the total discharge current. Electric current vortices were discovered in the plasma stream. The amplitude of the current in the vortices reaches 50% of the total discharge current. The maximum EUV radiation power was measured in the mode of MPC operation with local xenon injection. Power in the wave range 12.2 ÷ 15.8 nm achieves up to 16 ÷ 18 kW
