Abstract
Purpose
The purpose of the study is to show an improvement in resistance (permeability) and durability (residual strength) of modified wood compared to natural wood.
Design/methodology/approach
A relevance way to increase the durability and resistance of wood is processing with polymers. Novosibirsk State Technical University, Novosibirsk State University of Architecture and Civil Engineering (Sibstrin) and the Norilsk State Industrial Institute researched the resistance of elements of mine treatment plants made of wood modified with synthetic polymers. The study was carried out according to V.A. Kucherenko. Modification of such species as birch and pine can significantly increase wood resources by extending its service life and improving its physical and mechanical properties. Latex-organosilicon modifier was used as a modifier.
Findings
Latex clogs the capillaries of wood, preventing the penetration of aggressive solutions into it, and potassium methyl silicate interacts with hydrophilic OH groups, increasing the water-repellent properties of the surface of cells and wood capillaries.
Originality/value
The results of long-term and predictive tests of modified wood in aggressive environments of treatment facilities are presented. As a result, diffusion of aggressive media into the wood becomes more difficult and its resistance and durability increase.

Abstract
Purpose
The purpose of this paper is to determine the role of innovations in provision of competitiveness and innovational development of economy and overcoming of “underdevelopment whirlpools” in Russia and countries of Eastern Europe with the help of a special proprietary methodology.
Design/methodology/approach
The authors substantiate the concept and methodology of calculation of “underdevelopment whirlpools”, perform the analysis of development of “underdevelopment whirlpools” in Russia and countries of Eastern Europe and evaluate the influence of “underdevelopment whirlpools” on competitiveness of these countries’ economy.
Findings
The authors determine the perspectives of overcoming the “underdevelopment whirlpools” in Russia and countries of Eastern Europe and increasing their competitiveness with the help of innovation and develops practical recommendations for creation of innovational economy for the purpose of provision of high competitiveness and overcoming of “underdevelopment whirlpools” in Russia and countries of Eastern Europe and overcoming of strong and growing differentiation of the level of socio-economic development of their sub-systems.
Practical implications
Creation of innovational economy in Russia and countries of Eastern Europe is hindered by multiple obstacles (socio-economic and institutional), the success of overcoming of which determines the realization of a certain scenario of development of events.
Originality/value
The main conclusion is that creation of innovational economy can and should become a new vector of economic growth in Russia and countries of Eastern Europe and overcoming of strong and growing differentiation of the level of socio-economic development of their sub-systems.
