A Study on Green Economy Indicators and Modeling: Russian Context

This article aims to assess and forecast the dynamics of a regional green economy. The research relevance is determined by the need to develop theoretical and methodological basis of the green economy for the transition period and to identify criteria basis for assessing the state and regional level of it. The authors applied the modern methods, which allowed to model criteria considering data uncertainty and both static and dynamic criteria. The research process involved the methods of scientific analysis, comparison and synthesis, the theory of fuzzy sets, and fuzzy modeling. The main principles and methodology of the criteria evaluation for a regional green economy are proposed. The principal methodological approach in this research combines the current state and dynamics of the green economy in evaluating and forecasting the conditions of data uncertainty. The research results form a theoretical, methodological, and practical basis for assessing the current state and level of a regional green economy development, determining the effectiveness of environmental and economic programs, optimizing financial management, conducting environmental monitoring, and developing state plans.The research was funded by the grant of the Ministry of Education and Science of the Russian Federation to Perm National Research Polytechnic University # 26.6884.2017/8.9 "Sustainable development of urban areas and the improvement of the human environment.

Role of strontium cations in ZSM-5 zeolite in the methanol-to-hydrocarbons reaction

The selectivity of the methanol-to-hydrocarbons (MTH) reaction can be tuned by modifying zeolite catalysts with alkaline earth metals, which typically increase propylene selectivity and catalyst stability. Here we employed Sr2+ as its higher atomic number in comparison to the zeolite T atoms facilitates characterization by scanning transmission electron microscopy and operando X-ray absorption spectroscopy. Sr2+ dispersed in the ZSM-5 micropores coordinates water, methanol, and dimethyl ether during the MTH reaction. Complementary characterization with nuclear magnetic resonance spectroscopy, thermogravimetric analysis combined with mass spectrometry, operando infrared spectroscopy, and X-ray diffraction points to the retention of substantially more adsorbates during the MTH reaction in comparison to Sr-free zeolites. Our findings support the notion that alkaline earth metals modify the porous reaction environment such that the olefin cycle is favored over the aromatic cycle in the MTH, explaining the increased propylene yield and lower deactivation rate

Структура и физико-механические свойства гибридных композиций на основе ненасыщенной полиэфирной смолы и портландцемента

Strength and deformation properties of cured compositions based on unsaturated polyester resin and portlandcement were investigated in all range of concentrations. Optimal ratio of components which lead to high strength properties and high deformation ability was foundИсследованы прочностные и дефор- мационные свойства отвержден- ных композиций на основе ненасы- щенной полиэфирной смолы и портланд- цемента во всем диапазоне составов. Было определено оптимальное соотно- шение компонентов, при котором ком- позиционный материал обладает не только высокими прочностными свой- ствами, но и приобретает высокую де- формационную способность

Participative Budgeting in Smart Green City Context

Currently there are more than 7 billion people living on Earth and at least 1 million inhabitants globally live in cities. Modern cities start to use smart infrastructure and digitalization for sustainable development. The article is devoted to considering the smart technologies in city participative budgeting. City budget and financial and economic policy are under trends of digitalization and citizen's participation. Such attitudes and their formation depend on many factors, both public subjective and urban objective. At the same time modern smart cities involve the technological solutions introduction that significantly changes the urban life, which forms new behavioural patterns of interaction between citizens and the urban environment. Participation, individual capacities, and coordination are key factors for improving the efficiency of the financial and economic system and efficiency of urban management. Through these important aspects, it opens strategy perspectives in the fields of participative urban management and the implementation of digital governance. The paper investigates influence of digitalization in city budgeting and attracting citizens to city management
