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
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
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
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
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
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
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
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”
There was substantiated the purposefulness of introduction
in non-irrigated organic gardens of apple-trees of Kuban zone of in-row sodding of soil with naturally growing grasses providing the increase of plant resistance to abiotic stressors of summer period and as a consequence, stabilization of generative activity and the increase of fruit productivity
Based on empirical data obtained through the sociological poll, we present the analysis of the identification system of the Krasnodar region. The article places civil, ethnic, religious, regional identity in the hierarchy of the identity of residents of the region, we have also carried out the analysis of subjective importance of the various types of identity
