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
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
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
In the article the current version and some prospects of development of Universal cognitive analytical Eidos system - one of the oldest really working domestic universal systems of an artificial intellect widely applied and developing nowadays is shortly described
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
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
In this innovation section there are necessary agrotechnical receptions of care by the vineyard bushes, providing reception of high and qualitative crops of grapes. First of all, these are gartering of sleeves, fruit arrows, vegetating arms; operations with green bodies of a bush, fragmentation, extrapollination, stopping, girdling, stamping, etc., and also mechanization of care works
In the article we present a possibility of creation of the 2-speed synchronous and asynchronous electric motor and scientific bases for its design
In the article we consider illustrative images of rare
pumpkin cultures presented in stamps of different
countries. In this work, we analyze stamps which
represent rare pumpkin cultures. Stamps are reflection
of the economy; they portray agriculture and elements
of technology of agricultural production.
Cucurbitaceae family includes a large number of
species that are very different from each other in the
form of fruits, in purpose, in origin. The objective of
our study was to conduct a visual analysis of rare
pumpkin crops, which are used in the world; to reflect
the research progress on the introduction and the
achievement of breeding work. The article provides an
analysis of several cultures: momordika (Momordica
charantia L.), Kiva (Kiwano), horned melon, cucumber
Antilles, (Cucumis metuliferus L.); Akantositsios
Naudin (Acanthosicyos naudinianus L.); momordica
balsamina (Momordica Balsamina L.); koktsiniya
(Coccinia sessifolia L.); luffa cylindrical (Luffa
cylindrica L.); Lagenaria (Lagenaria siceraria
(Molina) Standl.); cucumber snake (Trichosanthes
anguina L.); antilles cucumber, anguria (Cucumis
anguria L.); african cucumber (Cucumis africanus
Lindl); wax gourd (Benincasa hispida (Thunb)
Cogn..); chayota or mexican cucumber (Sechium edule
Swartz). The analysis of the iconography of images of
rare pumpkin crops in stamps of different countries
allowed us to see the history of culture introduction of
wild pumpkin from the local and foreign flora
