Econometric modeling of the development of helicopter industry enterprises taking into account the innovation factor
Over the past decade, the Russian helicopter industry, which has been characterized by steady growth, has been confronted with difficulties caused by unstable political situation, fierce competition in world markets, rapid development and introduction of innovative technologies in this sector of the Russian economy. In order to maintain their position in the global market and increase the competitiveness of their products, Russian companies must adapt production to the changing demand for helicopters and pay increased attention to supporting the technological support of production with the latest materials, equipment and components of domestic production. The purpose of this study is to analyze the current state of the enterprises of the domestic helicopter industry on the example of the holding "Helicopters of Russia". To achieve this, the econometric package EViews10 was used and linear and nonlinear models were built, allowing to evaluate the existing and promising demand for Russian helicopters. As a result of the analysis of the models, factors that have a significant impact on the production of Russian helicopters were identified

Total metal composition analysis of MSWI bottom ash by ICP-AES for the estimation of its environmental impact
Detailed characterization of particle size fractions of municipal solid waste incineration bottom ash
Municipal Solid Waste Incineration Bottom Ash (MSWI BA) is of increasing interest as a secondary construction material worldwide. In most cases, MSWI BA is used in isolated conditions. However, according to the Dutch Green Deal B-076 in 2012, by 2020 all MSWI BA should be used in a non-sealed environment in the Netherlands. However, freshly produced. MSWI BA normally does not match environmental legislation due to high leaching of chlorides, sulfates, and potentially toxic elements. Because different particle size fractions of MSWI BA are of interest for designing optimized concrete recipes, it is beneficial to analyze the whole range of MSWI BA fractions in detail. In this study, 14 size fractions of MSWI BA were analyzed to determine the total elemental composition and leaching capacity, mineralogical composition, and shape variety of fine particles. From the point of view of mineralogical composition, 6 particle size fractions ( 22 mm) can be distinguished. All together the analyses showed that almost all fractions of the investigated MSWI BA can be used as secondary building materials. However, because the leaching of fine fractions is 5β10 times higher than of coarse fractions, all these fractions must undergo various treatments to allow them to match the environmental legislation. Thus, to decontaminate MSWI BA from potentially toxic elements, a division into three size groups is suggested: fine (<125 ΞΌm), medium (125 ΞΌm - 1 mm), and coarse fractions (over 1 mm)
