BIOLOGICAL FEATURES OF THE BLACK SOIL DEPOSITS IN THE BOTANICAL GARDEN OF SFU
Description
We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits

Description
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators

Description
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents exceeding the limiting current was measured by laser interferometry

01.00.00 Physical-mathematical sciences
Description
This article continues the works [1,2], devoted to the theoretical study of the basic laws of electroconvection caused by natural or artificial inhomogeneous conductivity of ion-exchange membranes in a smooth rectangular channel electrodialysis desalination unit. For this purpose, a mathematical model was created for a binary electrolyte electroconvection at overlimiting current modes in the form of a boundary value problem for a coupled system of the Nernst-Planck-Poisson and Navier-Stokes equations. We have studied the influence of heterogeneity on the ion-exchange membranes and ion transport electroconvection salt, calculated currentvoltage characteristic. The possibility of intensification of mass transfer due to the surface modification of ion exchange membranes was also shown

06.00.00 Agricultural sciences
Description
Combining ability with respect to “grain productivity” has been studied among thirty eight self-pollinated lines of maize of mid-early and early maturing in the system of hybrid combinations. The lines with high general (GCA) and specific (SCA) combinative ability have been hybridized. New high heterotic hybrids have been developed on the basis of lines with high GCA and SCA

06.00.00 Agricultural sciences
Description
In this article the results of the research of quality characteristics of Russian and foreign rice varietieswere observed. A possibility of using the data in characterizing germplasm from the collection was discussed
-
Description
The article presents methods of industrial tests of the of technical device utility model designed for boilers E-1,0-0,9G-3 QL-500, D-721 of small and medium capacity. The research is aimed at improving the efficiency of fuel combustion in the boiler furnaces due to uniform distribution of airflow when supplying it to the boiler burner

THE PROBLEM OF EFFECTIVE DEVELOPMENT OF THE PIG INDUSTRY OF THE ROSTOV REGION
Description
In the work we highlight the organizational and economic aspects of a profitable pork production in the market conditions. The article provides an analysis of the current status of the pig industry in the Rostov region. It also outlines solutions to the problems of development of pig breeding in the Rostov region

TO THE QUESTION OF THE NATURE OF THE SCIENCE-INNOVATIONS-PRODUCTION SYSTEM
Description
In this article in the light of a common social and philosophical traditions we present two trends, that define connection between science and material production: a trend of dependence of the science development from needs of production, and a trend of increasingly growing reverse impact of science on material production (along with engineering, technology, innovation). This article analyzes not only the individual elements of the "science-innovationsproduction", but also focuses on the study of the interaction and the relationship between its elements

TO THE QUESTION OF THE DEFINITION OF THE MODERN SCIENCE TERM
Description
The article analyzes the concept and the specific of science, discusses some patterns of functioning, integration and differentiation of modern science. We consider the difference of science and knowledge, nonexistence of sharp distinctions between the terms “science”, “innovation” and “engineering”
