Nonreflected vertical propagation of acoustic waves in a strongly inhomogeneous atmosphere
Using the linear theory of waves in a compressible atmosphere located in a gravitational field, we found a family of sound speed profiles for which the wavefield can be represented by a traveling wave with no reflection. The vertical flux of wave energy on these nonreflected profiles is retained, which proves that the energy transfer may occur over long distances.
This paper analyzes Belarus energy system, relations between Belarus, Kazakhstan and Russia in the framework of the Customs Union and the Common Economic Space. The consequences of the recent political crisis in Ukraine will inevitably lead to the review of the relations between the European Union and Russia. In these new conditions, the members of the Common Economic Space of Belarus, Kazakhstan and Russia must develop a new concept of energy security. This new concept should allow to decrease substantially the influence of the export of hydrocarbons on the economic development of abovementioned countries, thus increasing the competitiveness of their national economies. As a first measure, the members of the Eurasian Union should create the single energy market
The chapter constructs a new approach to legal approximation in EU-Russian energy relations
The article analyses the EU activity in assisting developing countries to develop energy sector throughperspective of the functional approach. The author identifies the EU approach by assessing EU compliance with the G8 commitments on assisting developing countries to develop energy sector. The assessment is made on the basis of the analysis of EU implementation of its commitments made in four major spheres of international engagement for energy development, such as ensuring developing countries’ access to modern energy sources, clean energy development, raw natural energy resources, sustainable management and environmental protection. In order to ensure comprehensive and unbiased assessment the author applies the methodology of global governance delivery function approach and compares EU compliance with compliance of other traditional donors such as USA and emerging donors such as Russia. In conclusion some recommendations on how to raise effectiveness in assisting developing countries to develop energy sector are made for the Russian Federation.
The paper explores the outcomes of Russian Federation G20 Presidency in 2013. The analysis is based on the model of balancing external conditions and national priorities for developing an agenda in informal institutions (supply-demand model). This analytical paradigm allows to reveal to what extent the Presidency has managed to ensure: 1) a high level of response to the key global governance challenges in the agenda and summit decisions; 2) a balance between national and other members’ interests in the Presidency priorities; 3) utilizing the institution’s capabilities; 4) conformity of the role chosen by the Presidency (organizer, mediator, political leader, national representative) to the combination of external and internal conditions.
Russia took over the responsibility for coordinating the G20 work from Mexico, accepting the rotating presidency of this premier forum for economic cooperation on December 1, 2012. The G20 met the fifth year of its work under conditions of a two speed recovery which by March 2013 transformed into a three speed recovery. Unsteady and sluggish growth, persisting imbalances and downside global economy risks demanded that this forum of the world largest economies concentrate the efforts on developing a set of measures aimed at boosting sustainable, inclusive and balanced growth and jobs creation around the world. These priorities constituted the core of the Russian G20 presidency concept, aimed at ensuring sustainable global growth and rebuilding of trust between the world economy different agents in accordance with the G20 mission and capability.
Consolidating efforts on its core economic and financial priorities, the G20 also launched collaboration to overcome such risks as increasing income disparities, chronic underinvestment into development of safe, secure and modern infrastructure, unforeseen consequences of regulation.
The analysis findings reveal that the Russian presidency managed to ensure a good balance of national interests and the partners’ prioritiesin the G20 agenda; utilizing the G20 capabilities to respond to the key global governance challenges. The choice of the presidency role depended on the nature of the issues and was defined by a combination of internal and external conditions. Thus, the acuteness of the problem for all summit participants determined demand for leadership in including into the economic forum agenda the debate on a peaceful resolution of the conflict in Syria. On employment and social policies the Russian presidency combining the roles of an organizer and a political leader helped upgrade the G20 dialogue to a new quality level.
A major success factor in deliberation and adoption of the comprehensive action plan on base erosion and profit shifting was the OECD capability to take responsibility for the plan development. With the OECD leadership, solid experts’ foundation, and a high level of relevance of the problem for all members, the presidency supported the process as the organizer.
On the topic of stimulating long-term investment, a priority for Russia as well as most of the G20 partners, the presidency managed to consolidate the efforts of several international institutions over a short period. On this priority, as well as on the financial regulation reform, the presidency acted as a representative of the national interests and an organizer. In developing the new development strategy the choice in favor of a combination of a mediator and an organizer proved most productive. As a result the G20 agreed a new cooperation for development outlook.
The presidency active collaboration with the international organizations and engagement with social partners was instrumental in harnessing their experts’ potential and enhancing the G20 transparency, legitimacy and effectiveness. The G20 institutions consolidation continued through development of new coordination mechanisms and strengthening accountability.
Under the Russian presidency the G20 reaffirmed its value as the premier economic cooperation forum. Emphasizing restoring strong and inclusive growth and employment while ensuring fiscal sustainability, the leaders for the first time in the history of the G20 stressed that the well-being of individual people should be at the center of the growth agenda. This consequential outcome of the five years collaboration might be a start of a new G20 agenda where inclusiveness is one of the pillars of growth.

The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
By using superconducting quantum interference device (SQUID) magnetometry, we investigated anisotropic high-field (H less than or similar to 7T) low-temperature (10 K) magnetization response of inhomogeneous nanoisland FeNi films grown by rf sputtering deposition on Sitall (TiO2) glass substrates. In the grown FeNi films, the FeNi layer nominal thickness varied from 0.6 to 2.5 nm, across the percolation transition at the d(c) similar or equal to 1.8 nm. We discovered that, beyond conventional spin-magnetism of Fe21Ni79 permalloy, the extracted out-of-plane magnetization response of the nanoisland FeNi films is not saturated in the range of investigated magnetic fields and exhibits paramagnetic-like behavior. We found that the anomalous out-of-plane magnetization response exhibits an escalating slope with increase in the nominal film thickness from 0.6 to 1.1 nm, however, it decreases with further increase in the film thickness, and then practically vanishes on approaching the FeNi film percolation threshold. At the same time, the in-plane response demonstrates saturation behavior above 1.5-2T, competing with anomalously large diamagnetic-like response, which becomes pronounced at high magnetic fields. It is possible that the supported-metal interaction leads to the creation of a thin charge-transfer (CT) layer and a Schottky barrier at the FeNi film/Sitall (TiO2) interface. Then, in the system with nanoscale circular domains, the observed anomalous paramagnetic-like magnetization response can be associated with a large orbital moment of the localized electrons. In addition, the inhomogeneous nanoisland FeNi films can possess spontaneous ordering of toroidal moments, which can be either of orbital or spin origin. The system with toroidal inhomogeneity can lead to anomalously strong diamagnetic-like response. The observed magnetization response is determined by the interplay between the paramagnetic-and diamagnetic-like contributions.
