The Arctic is a specific geographical region with extreme climate conditions, vulnerable environment, but rather intensive ongoing industrialization. The Arctic requires alternative solutions to ...provide energy supply to the energy consumers due to the growing energy demand and small-scale decentralized character of energy supply. At the moment, the largest part of energy consumption in the region is covered by hydrocarbon energy resources delivered from the mainland. Renewable energy technologies may be efficiently implemented to cover the needs of small scale decentralized energy consumers in the Russian Arctic, but at the moment they are applied on a very modest scale. The current study analyses and discusses the main challenges and risks related to renewable energy resources use in the Russian Arctic. Further, the study elaborates on the issues related to the environmental challenges and climate change-related threats, their relationship and influence on the technological choices of the future energy supply in the region, addressing the perspectives of sustainable development of the Russian Arctic.
The paper explores challenges of power supply for remote users through the case of the Northern Sea Route (NSR) supportive infrastructure development and specially nature protected areas (NPA) of the ...Russian Arctic. The study is based on a comprehensive analysis of relevant data of the state of renewable energy in the Russian Arctic. The paper gives policy recommendations on how to extend the use of renewable energy power plants in the region, optimize their input and increase cost-effectiveness and safety.
AvtoKMIMS, an automated integrated methodology for studying multicomponent systems, has been developed. It includes a general study algorithm using software for modeling phase complexes and ...newgeneration differential thermal analysis equipment for performing single confirming experiments.

The global energy system is experiencing a transformation. An analysis of the dynamics of global energy production and consumption indicates that a paradigm shift is occurring toward more reliable ...and sustainable energy sources with the dominance of natural gas. Even though the reserves-to-production ratio for hydrocarbons is declining, it is natural gas that can ensure the sustainable development of the energy system to meet the growing energy needs of humankind. Natural gas can also significantly reduce the environmental burden. In the medium term, it will be the main source of energy along a gradual transition to renewable energy. Natural gas can serve as a transition fuel within a broader deployment of hybrid energy technologies. Hybridization-the generation of energy using both fossil fuels and renewable energy sources-is one of the most promising areas of energy system development, contributing to a significant reduction in greenhouse gas emissions. In our opinion, hybridization based on natural gas is a "bridge to the future" for the world energy system.

The NESSiE Collaboration has been setup to undertake a conclusive experiment to clarify the
muon-neutrino disappearance
measurements at short baselines in order to put severe constraints to models ...with more than the three-standard neutrinos. To this aim the current FNAL-Booster neutrino beam for a Short-Baseline experiment was carefully evaluated by considering the use of magnetic spectrometers at two sites, near and far ones. The detector locations were studied, together with the achievable performances of two OPERA-like spectrometers. The study was constrained by the availability of existing hardware and a time-schedule compatible with the undergoing project of multi-site Liquid–Argon detectors at FNAL. The settled physics case and the kind of proposed experiment on the Booster neutrino beam would definitively clarify the existing tension between the

disappearance and the

appearance/disappearance at the eV mass scale. In the context of neutrino oscillations the measurement of
ν
μ
disappearance is a robust and fast approach to either reject or discover new neutrino states at the eV mass scale. We discuss an experimental program able to extend by more than one order of magnitude (for neutrino disappearance) and by almost one order of magnitude (for antineutrino disappearance) the present range of sensitivity for the mixing angle between standard and sterile neutrinos. These extensions are larger than those achieved in any other proposal presented so far.
