3D MODELING OF THE HISTORICAL OBJECT OF LANDSCAPE ARCHITECTURE EXEMPLIFIED BY PETROVSKY GARDEN IN PETROZAVODSK

abstract 1271703023 issue 127 pp. 353 – 362 31.03.2017 ru 713
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 On the basis of the historical documents, we created a 3D model of Petrovsky garden using of modern computer-aided design.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

3D MODELING OF TRANSPORT BINARY ELECTROLYTE IN THE GALVANOSTATIC MODE IN THE CONDITION OF ELECTRONEUTRALITY

abstract 1101506023 issue 110 pp. 351 – 362 30.06.2015 ru 967
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

60 YEARS IN THE RANKS: FEATURES OF MOLECULAR BIOLOGY OF BEZOSTAYA 1 WINTER WHEAT VARIETY

abstract 1181604035 issue 118 pp. 627 – 657 29.04.2016 ru 1246
This review is devoted to the 60 anniversary of the winter wheat variety (Triticum aestivum L.) Bezostaya 1 – a masterpiece of world selection. This variety played a great role in increasing total grain yields in the Kuban Region. It also was an important gene source for Russian and world breeding. This variety has initiated and was for many years a party to research molecular biological mechanisms of wheat frost resistance formation. The article summarizes data about the peculiarities of functioning of protein-synthesizing system it sprouts (coleoptilies) under the influence of hardening temperature (4oC): translational activity in vitro, poliribosomts, degree of polyadenilation and stability of total mRNA and specific mRNA translational elongation factor α subunit 1 (eEF-1 α). The in vitro (ommp) system, which adequately characterizes the relative mRNA stability in vivo was used for these measurements. The effects of cooling and light on mRNA stability were shown to be cultivar-specific. The hardiness of winter wheat has a positive relationship with the amount of RNA and DNA, and a negative correlation with the amount of magnesium cations in mature grain that can serve as a simple marker of frost resistance. The main feature of the variety Bezostaya 1 is high content of magnesium ions (Mg++) in RNA molecules and relatively low variation of Mg++-depending molecularphysiological responses for different environmental conditions. The knowledge gained in the study of variety of Bezostaya 1 contributes to the understanding of molecular biological processes that underlie the selection and determining its future success

abstract 1121508109 issue 112 pp. 1495 – 1507 30.10.2015 ru 1008
Introduction of mineral fertilizers is performed by centrifugal devices. By quantity of disks, centrifugal devices distinguish one disk and two-disk. On the volume of capacities for storage of mineral fertilizers distinguish bunker and body. Bunker contains volume from 0.5 to 1.5m3. Body has capacity more 2m3. Advantages of bunker centrifugal devices are noted. Material from the bunker moves on a centrifugal disk perpendicular to the rotation plane. At the time of material capture by shovels, crushing of particles and their reflection from shovels and the plane of a disk takes place. It leads to increase in unevenness of introduction of mineral fertilizers. At EMTP chair of the Kuban GAU the centrifugal device with supply of material along shovels is developed. The scheme of the centrifugal device is submitted. A device for introduction of mineral fertilizers contains the one-disk centrifugal device, the cone-shaped bunker and the cylindrical batcher. The batcher gate regulates supply of material on a disk. The technique of determination of design and technological data of the developed design is presented. The place of supply of material on a disk is regulated by rotation of the batcher round a vertical axis. The norm of supply of material on a disk changes the batcher gate. Preliminary control of a place of giving is made on model material with coefficient of friction of f 1. Under production conditions, turn of the batcher from initial situation is made depending on coefficient of friction of the f2 fertilizers. At f1 ˃ f2 turn of the batcher against the direction of rotation of a disk, and at f1 ≤ f2 turn of the batcher in the direction of rotation of a disk

A CLASSICAL PROBLEM FOR LOADED HYPERBOLIC-PARABOLIC EQUATION OF SECOND ORDER

abstract 1071503113 issue 107 pp. 1745 – 1756 31.03.2015 ru 938
The investigated and correct boundary value problem for mixed hyperbolic-parabolic equation of second order in a bounded domain is posed and studied in this work. Boundary conditions are of a classical nature. On line of type changes, which is also the line of the parabolic degeneracy for hyperbolic equations considered in the lower half-plane, a continuous bonding condition for the function itself and the breaking condition for the trace of the derivative is given. The main result is the proof of its unique solvability in the required class of functions. In particular, based on the properties of the operators of fractional integro-differentiation and in view of the ratio of the first boundary value problem for the heat equation, the question of the solvability of the original problem was equivalently reduced to the problem of solvability of the corresponding integral equation of the Voltaire second kind. In the hyperbolic part of the region, the question of solvability of the problem has also been reduced to the problem of solvability of the integral equation Voltaire second kind. The properties of the hypergeometric function of Gauss, as well as classical methods of integral equations were used. Thus it is proved the uniqueness and the existence of classical solution to the initial problem
