Description
There is a 2D mathematical model of ion transport binary salt with the main conjugate effects of concentration polarization in the overlimiting current mode: the bulk charge and the dissociation/ recombination of water, gravity and electroconvection and Joule heating the solution in the form of a boundary value problem for systems of differential equations with partial derivatives in the article. This system is presented in a form convenient for numerical solution. We describe the necessary boundary conditions. This article presents a theoretical study of the interaction of forced, gravitational and electroconvection, the dissociation / recombination of water molecules, and Joule heating of the solution and heat transport through membranes. We have constructed a mathematical model of two-dimensional non-stationary ion transport binary salt in a smooth rectangular channel desalting electrodialysis device using equations Nernst-Planck-Poisson, heat conduction and Navier-Stokes equations and the natural boundary conditions. For numerical solution we use the finite element method, with the splitting of task at each new time layer into three subtasks: electrochemical, thermal conductivity, hydrodynamic. Such approach to the development of numerical methods is the original and can solve arising in modeling boundary-value problems for a nonlinear system of partial differential equations

Description
The article presents a new approach to 2D modeling of transport of salt ions in EMC (electro systems: electrodialysis devices, electro-cells, etc.) under the condition of electrical neutrality with limiting and overlimiting current density. For definiteness as seen half of EMS channel EDA desalting (electrodialysis apparatus), the right border, which serves as a CEM (cation exchange membrane). The new approach in the use of partial differential equations of the first order, instead of equations of convective diffusion. A common method of transport modeling binary electrolyte in the EMS under the condition of electrical neutrality, is to use the equation of convective diffusion (partial differential equations of the second order). The article presents a new approach to modeling 2D transfer binary electrolyte in EMS under the same conditions, using partial differential equation of the first order for the decision, which does not require a boundary condition for concentration on the membrane surface. This allows you to simulate the transport of salt ions, as in prelimit and exorbitant current density and to determine the boundaries of the field of electrical neutrality

Petrovsky garden was founded in 1703 and is the most important historical object of landscape architecture in Petrozavodsk. Tikhon Balandin made a description and drawing of Petrovsky garden at the beginning of the 19th century. He completed his work by studying and measuring the fragments of the earthen fortress, blast furnace and the location of the destroyed palace, pond and birch garden. On the basis of the historical documents, we created a 3D model of Petrovsky garden using of modern computer-aided design. Threedimensional model of the garden allows viewing the object from different angles, gives an idea about structure and compositions of the garden on a new visual level. Some examples of visualization garden fragments were presented at the article. Now the garden doesn’t have its original structure. The historical garden layout and 3D model of object can be used for reconstruction of Petrovsky garden

Description
In the article we have derived mathematical models of non-stationary transport binary electrolyte in EMS (electromembrane systems: electrodialysis apparatus, electromembrane cell, etc.) for the galvanostatic mode. To be specific, as EMS viewed channel of desalting of EDA (electrodialysis apparatus) and EMS with RMD (rotating membrane disk). We present a formula expressing the intensity of the electric field through the current density and concentration. Also, we have received the differential equation for the current density. The fundamental point here is derived new equation for the unknown vector function of current density of the initial system of equations of Nernst-Planck. In addition, the article shows the output equation for the current density in three dimensions; we have proposed various methods for solving the equation of the current density and the boundary conditions for the current density. The proposed mathematical models of transport binary electrolyte are easy to be generalized to an arbitrary electrolyte. However, the corresponding equations are cumbersome. It should be also noted that the boundary conditions can be varied and depend on the purpose of a particular study in this regard, in this work are just the equation having the general form

Summary. In the article the developed by the author technique of dynamic (synchron-ously-diachronic) researches of complex lexical systems (etymological jacks and genetic pa-radigms of Russian lexicon) is offered. Results of such research can be presented in the form of the diachronic word-formation dictionary of an etymological jack. Its fragment is given in the end of the article.

In clause the various verbal and nonverbal methods applied by teleleaders for the most effective influence of a telediscourse on an audience are presented. Influence on spectators of the psychological factors which are found out at television receptions, appears more essential, than at influence on an audience other mass media. As shows the analysis, paralinguistic features also optimize perception.
