Bouncing scenario of general relativistic hydrodynamics in extended gravity
Authors: Shaikh A Y , Mishra B 
Published: January 2021

Abstract
In this paper, we have framed bouncing cosmological model of the Universe in the presence of general relativistic hydrodynamics in an extended theory of gravity. The metric assumed here is the flat Friedmann–Robertson–Walker space–time and the stress energy tensor is of perfect fluid. Since general relativity (GR) has certain issues with late time cosmic speed up phenomena, here we have introduced an additional matter geometry coupling that described the extended gravity to GR. The dynamical parameters are derived and analyzed. The dynamical behavior of the equation of state parameter has been analyzed. We have observed that the bouncing behavior is mostly controlled by the coupling parameter.
Remote weak-signal measurement via bound states in optomechanical systems
Authors: Li Xun , Xiong Biao , Chao Shilei , Zhao Chengsong , Tan Hua-Tang , Zhou Ling 
Published: January 2021

Abstract
A scheme for remote weak-signal sensors is proposed, in which a coupled-resonator optical waveguide (CROW), as a transmitter, couples to a hybrid optomechanical cavity and an observing cavity at its two ends. Non-Markovian theory is employed to study the weak-force sensor by treating the CROW as a non-Markovian reservoir of cavity fields. The dissipationless bound states in the non-Markovian regime are conducive to remotely transmitting a signal in the CROW. Our results show that a sensor with ultrahigh sensitivity can be achieved with the assistance of bound states under certain parameter regimes.

Abstract
Russia faces a promising task of integrated use of various resources of the Arctic, including tourism and recreation. In order to provide a sustainable socio-economic development of the polar regions and the country as a whole, it is necessary to conduct interdisciplinary studies of the resources and assimilation capacity of geographical systems based on methods used in socio-economic and physical geography, as well as in cultural geography. In the article the present conditions and trends in the tourism development of the Arctic Zone of the Russian Federation (AZRF) are considered as well as the features of its organization in the Barents Sea Region. The existing problems and prospects of the tourism development in the Arctic under modern conditions are discussed on the example of actively increasing cruise tourism in the region. Moreover, the factors limiting the development of Arctic tourism in the Russian Federation are considered. Conclusions based on comprehensive analysis of current opportunities and constraints in the Barents Sea region are drawn about the need for reconstruction and development of maritime transport and navigation infrastructure throughout the planned ship corridor along the Northern Sea Route (NSR) and the resumption of the ports of Dudinka, Dikson, Tiksi, Pevek and Provideniya. Further progress of mass ecological and cruise tourism in the Barents Sea basin requires scientific rationing of visits to protected areas and the organization of environmental events in places of excursions.

Abstract
Nowadays the development of Russian Arctic territories became a paramount problem of socio-economic development of our country and technical growth. Such a breakthrough can come true because of an effective state politics (rising of life grade, high standard investment protection by the law, strict requirement of protecting nature) and attracting of investment to comprehensive development of Arctic regions, including risk projects in long. However, the provisions of the state policy about the Arctic region is not completed today. The comprehensive way of region development is not shown. The specific Arctic conditions and especially a commerce control not completed too. The possibility of comprehensive socio-economics growth of the region is addicted to its potential, ability of adaptation for innovations and well risk management. All these factors define a relevance of risk research. In this article presented a risk analysis, defined and systemized the risk factors, on the base of spatial structuring in the coordinate plane, including trends of development and area features with region own potential and quality of socio-economic region development control. The case of risk and accounting have to become a part of the making an administration decisions to decrease the risk influents with using an integrated risk management.

Published: January 2021

Abstract
The publication is considered methodology and preliminary results of computer processing of vector ice charts and simulation of ice navigation by empirical statistical model, which was designed in the AARI. The model is result of generalization of multi-year special ship ice observations, produced by the AARI scientists. The Institute has unique archive of ice charts, which were made by recognition of satellite images, their composition and vectorization. The archive covers the period since 1997. Average navigation velocity and total time expenditure for sailing along a route can be used as the objective indexes of the ice navigation conditions. In the article is presented detailed description of the technique for preparing data for numerical experiments with the empirical statistical model by applying the ice charts from the archive. The data preparing is processed in ArcGIS by means of specially designed computer programs. The numerical experiments simulate ice navigation of “Arctica” nuclear icebreaker. The comparison between the average navigation velocity and time expenditure for sailing along the route “Sabetta Port – Kara Gate Strait” at simulation of ice conditions in the first ten-day interval of May 1998 and the same temporal interval of 2019 indicates significant improve of the ice navigation conditions.

Published: January 2021

Abstract
The quantitative value of the deflation processes in the steppe landscapes of Priolkhonie was obtained during field experimental studies in the summer seasons of 2017-2019 years. The quantity and properties of the transported particles were determined and statistical analysis of factors (parameters of test sites and weather conditions) affecting the erosion advancing was identified. The measurements were made with a set of dust traps at different heights from the surface, as well as a particle counter and a digital thermo-anemometer. Also, we surveyed the size (fractions) of trapped particles as well as soil samples from the upper soil horizon at the test sites. A comparative analysis of the native and transformed landscapes is carried out. According to results of multiple regression analysis, the main landscape factors that positively affect the deflation are: the quantitative ratio of the fractions of the granulometric composition of the upper horizon of the soil (the positive relationship with silt and dust content is most often expressed) and the steepness of the slope, and the negative relationship is most pronounced with rockiness soil and a projective cover of herbaceous vegetation. We found out that the development of deflation processes in the study area is primarily due to natural factors (features of the soil cover) and increases with anthropogenic impact, which affects the state of the vegetation cover and the particle-size composition of soils.

Authors: Sukhoveeva A B , Grigorieva E A 
Published: January 2021

Abstract
The quality of the living environment of the population as an external, objective factor, determines the level of comfort, affects its quality, health, reproduction and decision-making on migration. The quality of the environment is of a potential nature, serving as a basis for the socio-economic development of the region; it has a comparative nature in its original content and assumes a comparison of the specific indicators in spatial terms. Given the significant contrasts in environment at the Russian Far East (RFE), even small changes in natural and climatic conditions are crucial for determining quality of life of the population. Differences of environmental: natural, demographic, economic and social quality – were studied for regions at the southern part of the RFE. Sociological survey of women of reproductive age (17-45 years old) within both urban in rural areas in the Nanai District of Khabarovsk Krai, and Smidovichsky District of the Jewish Autonomous Region, gives a whole picture of their self-assessment of ecological, social and economic environment. Disproportions in the development, the main issues specific to individual areas, and spatial behavior of the residents are analyzed. Social and economic divergences are reflected in subjective estimates of native and non-indigenous women of reproductive age.
Optimization of environmentally-oriented resource management
Authors: Tsibulnikova M R , Sharf I V 
Published: January 2021

Abstract
Environmentally-oriented natural resource management is associated with the concept of sustainable development, which is based on the balance of interests between economic industry development and ecosystem conservation that gives greater urgency to the task of considering the regional development and the effect of mineral extraction on long-term regional development. The research purpose is comparative analysis of the contemporary development trends of oil-producing regions. The research hypothesis suggests that depletion rate of non-renewable resources, if not supported by institutional mechanisms of stimulating economic regional growth, results in development of conditions for “resource curse” as evidenced by the dynamics of different socio-economic indicators of regional development. The research areas are Tomsk and Irkutsk Oblasts and Krasnoyarsk Krai. The research is based on the evaluation methods of mineral resource depletion (oil) allowing for necessary magnitudes of rental income re-investment as well as economic-statistical methods of socio-economic dynamics to reveal the trends of regional development. The research results have shown that the regions do not receive the necessary amount of investments for economic diversification. Tomsk Oblast is characterized by impressive demonstration of “resource curse”, whereas Irkutsk Oblast is just at the early stage of that journey. The Krasnoyarsk Krai economy is more diversified. Calculation of socially dangerous depletion of oil reserves can serve as information for adequate justification of compensation approach towards sharing oil revenue taking into account re-investment of natural resource rent into socio-economic regional development.
Transformation of the ethnic cultural landscape of the Barguzin Cis-Baikal region (late 19th–early 21st centuries): resettlement and population dynamics
Authors: Tsydypova L S 
Published: January 2021

Abstract
The article presents the results of the study of the settlement of local communities and changes in the cultural landscape of the Barguzin Cis-Baikal region in the 19th-early 21st centuries. We discuss the formation and development of ties within local groups and the formation of settlements. The research is based on archival and literary sources as well as field materials of the author. Using the historical-geographical approach, we reveal the features of the formation of the population in the Barguzin Cis-Baikal region confined to the cattle breeding, hunting, and agricultural complexes. We determine the factors for the formation of cultural traditions of local groups, which continue to be a reference point in the habitation of territory. The research methodology takes into account the features of the convergence of time and territorial stages of change in ethnic and territorial identification. We consider the role of migrations, natural conditions and the economic specifics of new settlements, continuity, geographical and social mobility of the local population reflected in archival sources. Qualitative methods of cultural geography allow us to identify the ratio of ethnic composition in settlements in dynamics. The historically formed areas of geocultural complexes of local communities are a prerequisite for the sustainable development of unique landscapes. Most of them arose from a rethinking of the name by a native speaker.

Published: January 2021

Abstract
The article deals with the deep analysis of current cooperation of the countries of North-East Asia (NEA) on the formation of environmental policy in order to regulate further relationships, improve the ecological, socio-economic well-being of the population living in global instability. This consolidation includes geographically six states: China, Democratic People’s Republic of Korea, Mongolia, the Republic of Korea, Russian Federation and Japan). The format of subregional geographic approach in the comprehensive activities of the UNESCAP (Economic and Social Commission for Asia and the Pacific of UN), including the environmental sphere, turned out to be successful. Thus, the Subregional Program of North-East Asia for Cooperation in the Field of Environmental Protection (NEASPEC) became the most important and effective policy instrument in the 21st century. The development of sub-regional cooperation in the field of low-carbon urban spaces continues as a promising platform to address the challenges of global climate change and rapid urbanization – NEA LCCP (North East Asia Low Carbon City Platform). The article presents the results of the initiated Russian research on the example of the administrative center of the subject of the Siberian Federal District – Irkutsk – a large cultural, historical and economic city of the Baikal natural territory.
Transformation of geosystems of the Baikal natural territory (research and mapping)
Authors: Konovalova T I 
Published: January 2021

Abstract
The article deals with modern ideas about the transformation of geosystems and offers methodological foundations of its study. We considered the geosystem transformation in the context of changes in essential properties as a result of manifestation of transformative dynamics and geosystem evolution. It was revealed that the main trend of their transformations is largely determined by the impact of neotectonic processes. Singularities in the changes are assessed against the background of natural transformations of geosystems in the Late Cenozoic, when systemic connections, similar to modern ones, began to form. We noted that in most of plains and low-mountain areas of the area under study, a potential analogue of the natural complexes transformation in the Pliocene is currently being formed due to the development of aridization processes. We cite an instance of geosystem transformation of the Baikal natural territory. The methodology of mapping the transformation of geosystems, which is based on the mapping of system connections, transforming dynamics and evolution of geosystems, is considered. The research is based on information synthesis of data about the territory of Siberia, on the results of long-term ground route observations using the methods of complex physical and geographical research, comparative geographical, genetic, cartographic and GIS.
Analysis of the Influence of Differential Consolidation Settlement of Foundation on Redistribution of Internal Forces in Superstructure of Buildings
Authors: Huang Jianglong 
Published: January 2021

Abstract
In order to explore the influence of differential settlement of foundation on the internal force and deformation of super-frame structure, the stress and deformation of the traditional fixed support model and the elastic support model under the local effect of the differential settlement of the two columns are compared. The model without considering the settlement of the structure (Model 1), the traditional fixed support model (Model 2), and the vertical elastic support model (Model 3) are respectively constructed for analysis. The left end of the frame column and A/1-2 beam are taken as an example, the axial force of the frame column in Model 3 significantly decreases from -817.8kN to -415.3kN compared with Model 1, with a reduction of 49%; the shear force at the left end of the lower A/1-2 beam increases from 42.3kN to 43.5kN with an increase of 3%; and the bending moment increases from -27.2kN⋅m to 152.7kN⋅m. Those indicate the shear force and bending moment of the beam directly connected with the subsidence column under the action of the elastic support model are smaller than that under the action of the fixed support model. It is hoped that these change rules can provide reference for the design and reinforcement of similar projects in the future.
