The focusing of atomic and molecular particles near the nanotube axis using a model of a carbon nanotube (CNT) with discrete arrangement of atoms in its wall is studied. The degree of focusing of channeling particles in CNTs depends not only on the diameter of the CNTs, but also on its chirality. It is shown that the concentration of channeling particles in the tube's central part is higher for chiral nanotubes. © 2013 Pleiades Publishing, Ltd.

Solution of the three-dimensional ideal plastic layer compression by two rough dies is presented. Prandtl's assumption of a linear variation of the shear stresses over the thin layer thickness is assumed. Three-dimensional plastic flow, induced by friction contact stress vector on the dies, is analyzed using Haar and Karman's full plasticity concept. The cases of isotropic and anisotropic materials with Hill's yield condition are considered. © 2015 AIP Publishing LLC.

The mechanical properties of carbine are studied. The model is an array of chains located in a cell with periodic boundaries on each side. At a certain temperature, the model is subjected to axial stretching. The chain-deformation data are obtained; the Young’s modulus (3.11 TPa) is calculated. © 2015, Pleiades Publishing, Ltd.

The interaction between graphene on a substrate and charged particles moving with different rates (from thermal to Bohr’s) is studied by the molecular dynamics method. An approach is used, in which chemical-bond formation and breakage are taken into account by the ReaxFF potential. The characteristic dependences of the interaction forces of moving charged particles on the graphene-substrate distance are considered. Data on the polarization energy of the system as a function of the graphene-substrate distance are obtained. © 2015, Pleiades Publishing, Ltd.

The urgency of the problem under investigation due to the provisions of the new federal state educational standards of preschool education in the Russian Federation, according to which at the present stage of priority education is to implement a high level of social and communicative potential of the child's personality as a prerequisite for its successful adaptation and socialization in the society. This article discusses the results of a study whose purpose was to develop a program of formation of communication skills in preschool children with visual impairments. The leading approaches to the study of this problem is the position of humane pedagogy, Waldorf education and to imitate the example of the idea of a deep respect for the child's personality. Structure of the program includes games, aimed at developing the child's care to another, his virtues and experiences, fellowship with one another, assisting in real and game interaction, non-verbal learning and verbal means of communication. The implementation of this program in the experimental conditions showed the effectiveness of the proposed approaches in the organization of educational activities aimed at the formation of communication skills in preschool children with visual impairments, as an important factor for their adaptation in the social environment. © 2016 Vasilyeva.
