AbstractSpring waters with high-pCO2 content are widely distributed in the Sikhote-Alin region in Russia. Mukhen spa is one such spring located in the northern Sikhote-Alin region. This spa has two types of upwelling spring waters and exhibits distinct chemical signatures. One of the springs originates from a shallow aquifer and features hydrogen and oxygen isotopic ratios of meteoric water with a high 3He/4He ratio, whereas the other originates from a deeper aquifer and features a distinctly negative δ18O with a lower 3He/4He ratio. To understand this apparent discrepancy and the water circulation dynamics beneath Mukhen springs, we utilized all published data concerning the major solute elements and isotopic ratios of Mukhen spring waters and compared them with the He isotopic compositions on several springs in the far eastern region, which are newly analyzed in this study. The results show that the shallow aquifer comprises meteoric water that interacts with the crust enhanced by the gas component welling up from deep underground, while the fluid in deep aquifer fingerprinted the hydration reaction of silicate and involves a mantle component possibly delivered by a deep-seated fluid and/or gas upwelling along the tectonic fault through the western margin of the Sikhote-Alin region.

The article examines the historical aspects of the formation and implementation of the state strategy for the accelerated growth of the electric power industry in the Far East of the USSR in 1964—1991. The problems of power supply of the Far Eastern region of the country are analyzed, programs for the development of the regional electric power industry are considered, the difficulties of their implementation are revealed, structural changes in the industry and the results of electrification of the region are characterized. The author notes that the problems of regional energy supply had not been solved until the end of the Soviet era. The Far Eastern electric power industry continued to be a costly and lagging industry, slowing down the socio-economic development of the region.

The study of the history of librarianship is an urgent task of modern historical and library research. Its solution is possible if a large number of historical sources are identified and analysed. One of them is the pre-revolutionary journal “Librarian”, which differs from other periodicals of that time by its high informative content on the topic. Due to the lack of comprehensive studies of the “Librarian” journal as a historical source, this article for the first time considers this pre-revolutionary professional periodical as a source for studying the history of librarianship in Siberia and the Far East of the pre-revolutionary period. The purpose of this study is to identify and analyse the informative potential of the “Librarian” journal, which is useful for the reconstruction of the history of librarianship in Siberia and the Far East.The methodological basis of the research is based on the principles of historicism, objectivity and consistency. The article uses the methods of source studies, comparative and content analysis.The obtained results show that the journal “Librarian” is an important source for studying the history of librarianship in the Siberian-Far Eastern region. It contains numerous interesting facts about the libraries of the region, their structure and functioning, allows us to identify the sources of their financing and quantitative indicators of work, trace their dynamics, replenish the regional bibliography of special literature and restore the names of benefactors, Siberians and Far Easterners — members of the Society of Library Science.This study fully reveals the informative potential of this periodical, expands the idea of periodicals as important historical sources for the study of the history of librarianship of the country as a whole and its various regions. It can be useful in conducting specific historical studies of librarianship of the country of the pre-revolutionary period.

The Russian Far East

The monograph presents the search for solutions to the problems of the Far Eastern region. The proximity of China and the remoteness from the center of Russia make us look for effective measures to overcome the problems of settling the Far East in the context of sustainable economic development of modern Russia. The paper analyzes the problems of the Far East: in industry, agriculture, forestry, energy problems, environmental problems, and provides recommendations for their solution. Considerable attention is paid to migration problems. The experience of China is studied through the prism of bilateral cooperation with Russia. It is intended for students, masters, postgraduates, researchers dealing with issues of macroeconomic regulation and forecasting.

Attempt has been made to find the relationship between the basin groundwater flow and the current water chemistry of south-western part of Bangladesh considering their lithological distribution and aquifer condition. The correlation of water chemistry and basin groundwater flow is depicted in the conceptual model. The water-types of shallow groundwater are predominantly Mg-Na-HCO3 and Ca- Mg-Na-HCO3 type. In the deep aquifer of upper delta plain is predominately Na-Cl, Ca-HCO3 and Mg- HCO3 type. In the lower delta plain Na-Cl type of water mainly occurs in the shallow aquifer and occasionally Ca-HCO3, Ca-Mg-Na-HCO3 and Mg-HCO3 type may also occur in shallow aquifer of the eastern part of lower delta plain which could have originated from the recent recharge of rain water. Na- Cl type water is also found in the deep aquifer of lower delta plain. The origin of Na-Cl type water in the deep aquifer of lower delta part might be connate water or present day sea water intrusion. Fresh water occurring in the deep aquifer in the lower delta area is mostly of Mg-Ca-HCO3 and Na-HClO3 types. This type of water originate from intermediate or deep basin flow from the northern part of Bangladesh. The probable source of deep groundwater is Holocene marine transgression (Khan et al. 2000) occurred in 3000–7000 cal years BP and the deep groundwater of Upper Delta plain and Lower Delta plain is clearly influenced by deep basin flow coming from north part of BangladeshJournal of Bangladesh Academy of Sciences, Vol. 42, No. 1, 41-54, 2018

The article describes the directions of distribution of books for children in the Eastern regions of Russia that have appeared in the last decade. Based on a combination of landscape-reconstructing principles, surveys, and comparative typological analysis, the article presents data that expand previously studied aspects of the functioning of the main channels for the sale of books for children in the Siberian-Far Eastern region. It is shown that books for children are the largest segment of the Russian book market, which has been growing since 2008. At the regional level, they are widely presented in all book distribution channels: bookselling networks and independent stores; online stores; book departments of supermarkets (non-core retail); kiosks and stalls; book fairs. The purpose of the article is to analyze the current trends in the distribution of books for children in the region. Positive trends typical for the children book market in the Siberian-far Eastern region are identified. They are: the activity of children book supermarkets, the appearance of independent small stores of club-backstage format, the organization of specialized children Internet projects; increasing the importance of regional book exhibitions, fairs, festivals and holidays in the distribution of books for children; projects support by major Russian patrons. The significance of the study of new practices for the distribution of literature for children and youth in the region is determined by their influence on the formation of a new conceptual model for the popularization of reading, based on the idea of culture as a powerful lever of socio-economic development of territories.
