Binary open clusters in the Milky Way: photometric and spectroscopic analysis of NGC 5617 and Trumpler 22

Using photometry and high resolution spectroscopy we investigate for the first time the physical connection between the open clusters NGC 5617 and Trumpler 22. Based on new CCD photometry we report their spatial proximity and common age of ~70 Myr. Based on high resolution spectra collected using the HERMES and UCLES spectrographs on the Anglo-Australian telescope, we present radial velocities and abundances for Fe, Na, Mg, Al, Si, Ca and Ni. The measured radial velocities are -38.63 +/-2.25 km/s for NGC 5617 and -38.46 +/-2.08 km/s for Trumpler 22. The mean metallicity of NGC 5617 was found to be [Fe/H] =-0.18 +/-0.02 and for Trumpler 22 was found to be [Fe/H] = -0.17 +/-0.04. The two clusters share similar abundances across the other elements, indicative of a common chemical enrichment history of these clusters. Together with common motions and ages we confirm that NGC 5617 and Trumpler 22 are a primordial binary cluster pair in the Milky Way.Comment: 7 pages, 3 figure, accepted by MNRA

Ecological situation in the modern Russian Federation: comparison with other countries as a basis for new ideas for the development of the state

Most of the existing environmental problems have not been resolved yet, and some of them become aggravated. There is awareness that the tools that have been used so far to solve these problems can’t handle them. There is an interest in the analysis of existing environmental problems among social activists. The purpose of this article is to develop new ideas and directions for improving the environmental policy of Russia, based on an analysis of existing problems. In work elements of comparative and systematic approaches and general scientific methods of analysis, synthesis, deduction and induction were used. The main environmental problems that exist in Russia are: waste management issues, water pollution, deforestation, skepticism towards alternative and green energy. The study revealed the need to consider new trends in the environmental policy of Russia from the standpoint of political ecology. Among the necessary measures, it is worth noting the following: the introduction of a new ideology that will put in the first place the harmonious relationship between nature and a human; introduction of environmental education; a new system of preparing the specialists, including courses on an environmentally oriented lifestyle; information policy, revealing the essence of existing environmental problems; support for environmental organizations; introduction of a new approach to alternative energy and green technologies

The Role of the EAEU and the SCO in the Eurasia Environmental Safety Space Formation

Recently, most of the existing environmental problems have not only not been solved but have also worsened. There is a growing understanding in the public consciousness that the tools that have been used so far in solving these problems do not cope with the tasks formulated, among other things, in the UN Sustainable Development Goals. Accordingly, the interest in analyzing existing environmental problems and finding ways to solve them is taking an increasing place in the process of defining and implementing the policies of most states and their interaction with activists of environmental social movements.Aim. Development of new ideas and directions for improving environmental policy, including within the framework of increasing the intensity of integration processes in the Eurasian space covering the EAC and SCO countries.Tasks. In the article are analyzed the experience of EAC and SCO countries in the process of ecological safe space creation.Methods. In the article were used elements of comparative and systematic approaches and general scientific methods of analysis, synthesis, deduction, and induction.Results. The study revealed the need to consider new trends in the environmental policy of the Russian Federation also under development of integration processes within the Eurasian space from the perspective of political ecology.Conclusion. Based on the analysis, the following main environmental problems that exist in the Russian Federation were identified: waste management issues, water pollution, destruction of forests, skepticism about “alternative” and “green” energy. However, environmental problems, as a rule, affect more than one country, so they need to be solved through integration with other states. Now the development of a “green” economy is a promising direction within the Eurasian space

Assesment of the impact of assets value on financial statuses of regions

© 2014, Mediterranean Center of Social and Educational Research. All rights reserved. We offer to supplement existing approaches to evaluation of financial statuses of governmental units with an index of assets availability which are the basis of their activities. Necessity for consideration of assets dynamics, their structure, as well as quality of their management is proved in the course of evaluation of financial statuses of governmental units. The article makes the evaluation of influence of various assets of constituent entities of the Russian Federation, included into the Volga Federal District, on their financial statuses level; they have been graded with a glance to assets dynamics changes

The Current State of the “Green” Parties: Russia, Europe, the World

The article is devoted to the study of the current state of the «green» parties in the world as a whole, as well as in Europe and the Russian Federation in particular. The history of the formation of the «green» parties is also revealed and their common features are analyzed. In addition, the difference between the European «green» parties and the Russian ones is considered there. An important part of the study is the analysis of the percentage of representatives of «green» parties in the legislative authorities in the countries. As a result of the research, the author comes to several conclusions: currently, «green» parties exist in almost half of the countries where the existence of parties is possible as such. In a quarter of these countries, representatives of these parties are in the government, and about 4% of them are in the ruling coalitions. Nevertheless, for half a century, this is quite a great achievement for parties that were once considered oppositional. Most of these parties are represented in the European parliaments, but they have a number of differences from the «green» parties of the Russian Federation, which is also noted in this article
