Combustion of a plane hydrogen microjet at subsonic and supersonic speeds
Authors: Kozlov V. V. , Grek G. R. , Litvinenko Yu. A. , Shmakov A. G. , Vikhorev V. V.
Published: May 2019

In this paper, we presented the results of experimental studies of the diffusion combustion of a plain hydrogen microjet flowing from a slit micronozzle at subsonic and supersonic speeds. For the first time, four scenarios of diffusion combustion of a plain hydrogen microjet including supersonic combustion in the presence of supersonic cells in both air and hydrogen are presented. The stabilization of the subsonic combustion of a hydrogen microjet was established to be due to the presence of a «bottleneck flame region» while the stabilization of the supersonic combustion of a microjet was found to be associated with the presence of supersonic cells. The observed hyster­esis of diffusion combustion of a plain hydrogen microjet depends on both the method of igniting the microjet (near or far from the nozzle exit) and the direction of change in the rate of its outflow (growth or reduction).

New 4,5-diaza-9,9'-spirobifluorene derivative 8 with two electron-accepting perylene diimide moieties has been prepared. The compound 8 was characterized by NMR spectroscopy, elemental analysis, UV-spectroscopy and cyclic voltammetry. Energies of HOMO/LUMO levels are of -5.81 eV/-3.89 eV; Egopt and Egech values are of 1.75 eV and 1.92 eV, respectively. Low-lying energy levels and strong absorption in the visible region of UV- spectrum indicate the potential use of the compound 8 as a new promising electron acceptor in nonfullerene polymer solar cells.
Rare-metal granites from various zones of the early mesozoic magmatic areal (Mongolia): geochemical and petrogenetic features
Authors: Antipin V. S. , Perepelov A. B. , Odgerel D.
Published: May 2019

This study is aimed at comparative analysis of the chemical evolution, age, and petrogenetic features of the Li–F granites from various zones of the Early Mesozoic magmatic areal. The newly obtained geochemical data preclude the formation of rare-metal Li–F granites by processes of magmatic differentiation of a palingenic granitic magma, parental to the Baga–Khentei Pluton. The rare-metal granites of the peripheral zone of the Early Mesozoic magmatic areal, compared to their counterparts from the central part (the Baga–Khentei Pluton), are more enriched in some elements that accumulated intensively during fluid-magmatic differentiation (Li, Rb, Sn, Ta, and F), often forming a concentrated mineralization. This corroborates the potential of rifted fringes of batholiths in the context of the connection of rare-metal mineralization and magmatism. The geochemical specifics of the Khentei intrusion granite from the central part of the Early Mesozoic magmatic areal may imply a deeper source related to the mantle plume.
Geomagnetic field disturbances from the fall of the Lipetsk (june 21, 2018) and Chelyabinsk (february 15, 2013) meteorites
Authors: Spivak A. A. , Riabova S. A.
Published: May 2019

Based on the Chelyabinsk (February 13, 2013) and Lipetsk (June 21, 2018) events, disturbances in the Earth's geomagnetic field, which were induced by the fall of these meteorites, were studied. Based on the data provided by geomagnetic observatories of the INTERMAGNET network and the mid-latitude Mikhnevo geophysical observatory (IDG RAS), it was established that the fall of meteorites through the Earth's atmosphere, in general, induces geomagnetic disturbances of up to 5 nT at distances up to 2700 km from the impact point of a cosmic body; the maximum effect is reached with a delay time ranging from ~5 to ~10 min, and the duration of the period of the induced geomagnetic field disturbances varies from ~5 to ~20 min. The estimation dependencies of the amplitude and duration of induced geomagnetic disturbances from a distance from the meteorite impact points are proposed.

Published: May 2019

It has been established that the activity of recombinant human peroxiredoxins (Prx1, Prx2, Prx4 and Prx6) inhibits by natural dicarbonyls formed during free radical peroxidation of unsaturated lipids (malonic dialdehyde) and oxidative transformations of glucose (glyoxal, methylglyoxal). The possible role of peroxiredoxins activity decreasing under oxidative and carbonyl stress is discussed as an important factor that includes molecular mechanisms of vascular wall damage in atherosclerosis and diabetes mellitus.

The paper presents a brief description of the life and scientific creativity of Academician A.A. Samarskii, an outstanding scholar with a worldwide reputation, the founder of the Russian tradition of mathematical modeling and the creator of the fundamental theory of difference schemes. The evolution of Samarskii’s concept of mathematical modeling and computational experimentation is traced from the end of the 1940s to the era of the information society. The basis of this concept and the associated research methodology was Samarskii’s concept of the famous “Model–Algorithm–Program” triad, which provides a universal sequence of actions for conducting research and development for the most critical fields of modern science. The paper presents examples of fundamental and applied results obtained by A.A. Samarskii and his disciples in crucial areas of scientific and technological progress.
Distributed generation based on cutting-edge technology and digital systems
Authors: Kashin A. M.
Published: May 2019

In rankings of technologically advanced Asian, North American, and European countries for their achievements in electrochemical technology, Russia usually finds itself in the ROW (Rest-of-the-World) category. However, our country is exceptionally well-positioned to take a leadership role in this field. Russia’s InEnergy Group, with its core business of developing electrochemical technology and providing unique electrochemical solutions to individual businesses, has created a favorable environment for drawing science, manufacturing, and the global market together. To that end, the Group has established a Distributed Research and Development Center, which has assembled world-class experts in fuel cells and multi-purpose power-supply systems. In addition, the Group has considered the Electrochemistry project as part of a Comprehensive Research Program, called Distributed Generation based on Cutting-Edge Technologies and Digital Systems, which is presently in the drafting stage. The project is designed around the concept of network-centric design and is expected to outpace rather than merely replace imports. In other words, the project will support the development and deployment of electrochemical technologies to compensate for imports that might be needed even in the future. This industrial effort, coordinated with research in the academic community, will create new technological opportunities that might propel Russia into a leading position in the global market for chemical sources of electric power.

The paper presents pioneering data on the comparative study of impact glasses from the Zhamanshin crater and lunar regolith (delivered by the Luna 16, 20, and 24 probes). The data were acquired using analytical techniques of ultrahigh spatial resolution. Many of the melt and condensate impact glasses, both terrestrial and lunar, are similar in inner structure and composition, which were controlled primarily by the physics of the impacts and similar compositions of the targets.
Tectonic position of the Early Neoproterozoic–Early Paleozoic metamorphic belts within the Tuva–Mongolian terrane of the Central Asian Orogenic Belt

Published: May 2019

The Tuva–Mongolian terrane (TMT) of the Central Asian Orogenic Belt is a composite structure with a Vendian–Cambrian terrigenous-carbonate cover. The formation of the northern part of TMT is marked by the granitoids of the Sumsunur Complex with an age of 785 ± 11 Ma. The Sangilen and Khan-Khukhay blocks of its southern part also form a composite structure, which originated during Early Paleozoic(500–490 Ma) low-moderate pressure regional metamorphism reaching amphibolites-granulite facies. The earlier high-pressure metamorphism was established in the Moren Complex of both the blocks. In the Sangilen block, this metamorphism reached conditions of kyanite-garnet-biotite-orthoclase subfacies of amphibolites facies (temperature ~750oC, pressure 9–10 kbar). The upper age limit of this metamorphism is determined by granites with an age of 536 ± 6 Ma, which cut across migmatized biotite gneisses of the Moren Complex. The latter are intruded by the granitoids of the Ortoadir pluton, which were previously dated at 521 ± ± 12 Ma (U-Pb method, TIMS). Its emplacement predated the Early Paleozoic low-moderate pressure metamorphism, the timing of which is constrained by syn- and postmetamorphic granitoids with ages of 496 ± 4 and 489 ± 3 Ma. The age of 513 ± 4 Ma established for the granitoids of the Ortoadir Complex in the Khan-Khukhay Block more accurately constrains the lower age boundary of collision processes. This determined the amalgamation of the fragments of the high-pressure metamorphic belt with basement and carbonate-shelf cover units of the Tuva–Mongolian terrane, as well as the upper age boundary of early metamorphism. The timing of the main mappable structure of the Khan–Khukhay Block and low-moderate pressure regional metamorphism is marked by the synmetamorphic granitoids with an age of 505 ± ± 2 Ma. In general, the metamorphic rocks of the Sangilen, Khan–Khukhay, and Kaakhem blocks can be considered as fragments of the Late Ediacaran high-pressure metamorphic belt, which were amalgamated to the western margin of TMT within 515–505 Ma, after emplacement of the granitoids of the Ortoadir Complex, and were reworked by regional Early Paleozoic low-moderate pressure metamorphism.
A technique for calculating the enthalpy of silicate melt of arbitrary composition
Authors: Bychkov D. A. , Koptev-Dvornikov E. V.
Published: May 2019

The Kirchhoff equation was used to develop a method for calculating the enthalpy of silicate melt of any arbitrarily chosen composition with regard for the latent heat of fusion. To do this, the following two problems were solved: (a) the coefficients of the heat capacity equation of a silicate melt were revised and (b) the partial molar enthalpies of formation of melt components from elements at standard state were determined. The uncertainty in calculating the heat capacity of silicate melt at 95% significance level is no greater than ± 0.7 J · mol–1 · K–1. A weak but statistically significant temperature dependence of the heat capacity was determined. The enthalpies of melts calculated using the method are comparable with the values obtained by other techniques. The calculation error at 95% significance level is ±2 relative %.
The origin of adakite-like magmas in the modern continental ollision zone: evidence from pliocene dacitic volcanism of the Akhalkalaki lava plateau (Javakheti highland, Lesser Kaucasus)
Authors: Lebedev V. A. , Vashakidze G. T. , Parfenov A. V. , Yakushev A. I.
Published: May 2019

The paper reports the isotope-geochronological and petrological-geochemical studies of the Pliocene moderately-acid volcanism of the Akhalkalaki Plateau in the central part of the Lesser Caucasus (Javakheti highland, Georgia). K-Ar dating showed that young dacitic lavas and pyroclastic rocks were formed in the Mid-Pliocene (3.28 ± 0.10 Ma) in relation with the explosive–effusive eruptions of small composite volcanic cones and formation of minor extrusive domes confined mainly to the eastern margin of the region. Isotope-geochronological data in the combination with results of structural drilling indicate that the considered short-term pulse of the volcanic activity occurred during a short gap between two phases of the Pliocene–Early Pleistocene mafic magmatism widespread within the Akhalkalaki plateau. The studied Pliocene dacites were erupted at the post-collisional stage of the evolution of the Lesser Caucasus, but bear petrological-geochemical affinity of adakitic series. They are characterized by the steady presence of amphibole phenocrysts, the elevated contents of Sr, Ba, LILE and the lowered contents of Y, Nb, Ta, and HREE, and have depleted Sr isotopic composition (87Sr/86Sr < 0.7045). Analysis of petrogenetic models earlier proposed to explain the generation of adakite-like magmas in the modern collision zones showed that the origin of the Pliocene dacitic lavas of the Akhlkalaki plateau is best described by the crystallization differentiation of watersaturated calc-alkaline basaltic melts with removal of common mafic rock-forming minerals (first of all, amphibole and pyroxene) and accessory phases (apatite, titanite, Ti-magnetite) as cumulus minerals. Crustal assimilation of evolved magmas only insignificantly contributed to the petrogenesis of the dacites.
Duration and geodynamic nature of giant Central Asian batholiths: geological and geochronological studies of the Khangai batholith

Published: May 2019

In the Late Paleozoic and Early Mesozoic, during about 100 m.y., the world’s three largest batholiths (Angara-Vitim, Khangai, and Khentei, each up to 1 000 000 km3 in volume) had formed within the limits of the Central Asian orogenic belt. Considering the case of the Khangai batholith, the problem of how, when, and why such an extensive granite formation took place is analyzed. The geochronological data for granitoids of the batholith by U–Pb (ID-TIMS) and 40Ar/39Ar dating methods are systematized to distinguish three age groups of rocks. These rock groups are correlated to the geological events occurred in the region. The earliest group includes granitoids formed in the interval of 302–283 Ma. They tend to the western and southern framings of the batholith and correspond to the fragments of two igneous belts that crossed the region, where the batholith formed later, and reached the areas far beyond. The youngest group of igneous rocks (230–200 Ma) is developed in the eastern periphery of the batholith and corresponds to the marginal part of the large Early Mesozoic Mongol-Transbaikalian igneous zone, with the main part being located far away to the east of there. Igneous complexes that formed in the interval of 273–238 Ma correspond to the batholith proper. They are concentrated within the zone of 350 × 400 km in size and are represented by rocks of two associations: granite-granodiorite (Khangai complex) and granite-leucogranite (Sharaus Gol complex). The coeval analogs of these rocks are reported only in the framing of the batholith.

The comparison between the Khangai batholith and two other giant ones (Angara-Vitim and Khentei) revealed their similarity in terms of structure and evolution. They are all composed of similar rock associations and are of comparable sizes and age intervals of formation. For example, the Angara-Vitim and Khentei batholiths formed mainly in the intervals of 305–275 and 229–195 Ma, respectively. The obtained estimates of formation time of ~30 m.y. should seemingly be considered as the time necessary for chambers of anatectic magmas, which to certain degree formed giant (~1 000 000 km3 in volume) batholiths, to cool down in the Earth’s interior. The formation of giant batholiths is attributed to the effect of mantle plumes on the lithosphere of a young fold zone that appeared as a result of accretionary-collisional events in the marginal part of the Siberian paleocontinent.
The Cambrian molluscs of Australia: overview of taxonomy, biostratigraphy and paleobiogeography
Authors: Parkhaev P. Yu.
Published: May 2019

Cambrian malacofauna of Australia is among the most taxonomically diverse among time equivalents. By a number of valid mollusc species Australian Cambrian competes with Siberian and Chinese formations. Up to date, 80 valid species and 12 forms in open nomenclature, apparently representing new undescribed taxa, have been recorded from the Lower–Middle Cambrian successions of Australia. In addition, 6 species names can be considered as junior synonyms. Distribution ranges of mollusc species plotted over the modern stratigraphic scheme reveal four major molluscan evolutionary assemblages in the interval of Tommotian–Undillan stages. In paleogeographic aspect, the Cambrian malacofauna of Australia has 29 species in common with Siberian Platform, Kazakhstan, Altai-Sayan, Transbaikalia, Mongolia, South and North China, Morocco, Antarctic, Europe (Denmark, Germany), Greenland, North America, and New Zealand, providing important correlation links between these regional stratigraphic schemes.
Approaches to the allocation of periphery and рeripheralization in the spatial development of modern Russia
Authors: Anokhin A. A. , Kuzin V. Yu.
Published: May 2019

The article is devoted to the issues of periphery and peripheralization of the spatial development of Russia, a significant part of the territory of which has experienced the negative direction of social and economic development during the transition to a market economy and continues to undergo it at the present time.

The article discusses the theoretical approaches of Russian and foreign authors to the definition of the concepts of «periphery», «peripheralization of space». Based on the use of methods of comparative analysis and systematization, the authors identified six main approaches of researchers to the definition of the concept of «periphery»: positional, functional, problem, generative-translational, social, subjective, and also revealed the content and peculiarity of each approach.

The authors highlighted such basic properties of the periphery as diverse remoteness, economic degradation and social marginalization, poly-scale character, migration outflow, ubiquity and relativity, weak involvement in global economic relations. A system of indicators characterizing the periphery in accordance with the selected approaches is proposed.

On the basis of the conducted research, it was concluded that the spatial development of individual centers of Russia is taking place with the spatial degradation of its most part, which significantly actualizes the question of the future of the Russian periphery and its impact on the spatial development of the country as a whole. Due to the weakness of its own potential, the Russian periphery cannot act as an independent attractor of socio-economic development and requires strengthening state regulation measures based on the competitive advantages of each territory.
Development of the legal framework of recreational nature management in Russia
Authors: Isachenko T. E. , Kosarev A. V.
Published: May 2019

The article traces the history of the development of legal legislation related to the recreational development of the territory. Five stages of formation are considered. For each stage the types of recreational areas are characterized. These types are reflected in the regulatory legal acts of each time period. Recreational nature management takes a significant place in the structure of nature management in Russia. It's modern regulatory and legal framework is analyzed in particular. The study revealed the main problems of involving territories in the recreational sphere from the standpoint of the main normative documents — the codes of the Russian Federation: Land, Water, Forest and Town-planning and Federal laws supplementing them. The analysis of the current legislation and the terminology used in it provides the basis for the correlation of recreational nature management with five categories of land: forest lands, agricultural lands, water resources, build-up areas (settlements) and lands of specially protected areas and objects. The necessity of integration of the concepts of «cultural landscape», «landscape planning» and «landscape plan» in the legal field with the aim of streamlining the process of planning and design of recreational areas and synchronization of the legislation in the sphere of recreational nature management is suggested in the article.
Prediction of modern geological processes in the territory of Russia and CIS countries in the early XXI century
Authors: Mal’neva I. V.
Published: May 2019

The paper considers the modern problems in prediction of hazardous geological processes in the XXI century. It is noted that the peculiarities of the prediction of the most hazardous geological processes (landslides, mudflows, etc.) are connected with global climatic changes and a technogenic factor. The assessment of climatic changes and the most largest catastrophic disasters was carried out with use of the typification of atmospheric circulation in the Northern hemisphere, developed by B. L. Dzerdzeevskii. The data of the typification for the period from 1899 to 2017 can be found on the Internet website www. atmospheric-circulation.ru in open access. The major disasters are considered that caused an activation of landslides and mudflows. The interaction of natural and technogenic factors is described during these disasters. The prediction took into consideration the changes in solar activity and features of space weather.
The possibilities of the geological border oriented graph at formal description of 3-dimensional large-scalegeological model
Authors: Mironov O. K. , Karfidova E. A. , Svalova V. B.
Published: May 2019

The article deals with the present state of the formalized description of a 3-dimensional geological model with the consideration of the problems arising from the increase in scale and the transition from the geological bodies distinguished by stratigraphic principle to those identified by lithology-stratigraphic and engineering-geological divisions. An approach to solving these problems is proposed. It is shown that the problem of correctly determining the sequence of occurrence of lithological-stratigraphic subdivisions can be solved as a problem of topological sorting of vertices of an oriented graph. For the first time, the requirements for non-local alignment of geological sections are set.
Regime of karst and glacial lakes at the carboniferous plateau of Tikhvin Ridge in the Northwest of the Russian platform
Authors: Belov K. V. , Ignatov P. A. , Goryunov E. Yu.
Published: May 2019

The studied territory is restricted to the central part of Tikhvin Ridge composed of karstified terrigenous and carbonate deposits of Carboniferous age. The central part of the area is a flat watershed dividing the rivers flowing northwest to Lake Ladoga and those flowing southeast to the Rybinsk water reservoir. The considered territory lies within the Msta River basin subjected to the recent tectonic uplift, forming landforms of Alpine type. Considerable longitudinal sloping of rivers provide intense surface and subsurface runoff (the active hydrodynamic regime). In the considered territory, the lakes are known with their areas changing significantly and quickly enough (months or years). The water in lake basins may disappear or fill them back completely. According to observations, these abrupt decreases and rises in water level do not correlate with seasonal floods, high water and low water periods. The phenomenon of drying and (what is particularly interesting) subsequent filling of lake basins with water is obviously related to the karstic groundwater regime, which is of scientific interest. The up-to-date research data include state geological maps (scale 1:200 000); topographic maps (scale 1:100 000); space images of the free-access Google Planet Earth Internet service, taken in summer and autumn 1984-2016; and weather service data. Cartographic materials were processed in GIS. The analysis of collected data allowed us to distinguish between two types of lakes, i.e., those with insignificant and substantial changes in area with time. Water reservoirs of the first type located on water-permeable moraine Quaternary deposits are classified as glacial. Other lakes overlying immediately Carboniferous deposits, have funnels in the basin bottom and are considered as karstic. The areas of two glacial and three karstic lakes have been measured (by interpreting satellite images) within the central part of the Carboniferous plateau at the Tikhvin Ridge. Variation in the glacial lake areas in the span of 33 years were found to be not crucial, being directly related to annual atmospheric precipitation not correlating with the changing areas of karstic lakes. Karstic lakes reveal 2-, 3- and 12-year-long cycles of significant changes in areas. These changes show decreases and rises in their levels and volumes. They are correlated among all karstic lakes irrespective of the average annual volume of atmospheric precipitation. It points to the significant participation of groundwater in alimentation of karstic lakes belonging to a single karstic water-bearing complex of underlying Carboniferous deposits. Authors relate the recurrent shallowing and filling of karstic lakes to the modern alternating tectonic movements leading to variation in permeability of karstic groundwater-bearing deposits.

Published: May 2019

To ensure a given rate of seed soybean seeding, a substantiation of the design parameters of the sowing disk is provided by the nesting method: the number of cells and the distance between the cells, depending on the diameter of the disc and the linear dimensions of the cell. An analytical relationship were obtained to determine the distance between the seeds in the nest and between the nests, depending on the central angles between the centers of the cells in the group and the groups of cells on the lateral surface on the sowing disk, taking into account the seeding rate and the number of cells. The necessary number of cells on the sowing disk its critical linear speed is justified taking into account the seeding machine speed at which the cells are guaranteed to be filled. As a result of the numerical experiment, the following data were obtained: for a given diameter of the sowing disk 0.21m with a cell diameter of 0.008 m and a cell depth of 0.005 m, the total number of cells on the side surface of the disk is 120 pieces, the central angle between the cells in the group is 20, and the central angle between groups of cells is 50.

Modern Batı Düşüncesinde Dini Konumlandırma Problemi
Authors: ÖGCEM Ergin
Published: May 2019

Din dâhil her söylem,
geldiği ortamın mevcut düzen ve anlayışına bir meydan okuma şeklinde tezahür
etmiştir. İnsanı konu edinen tüm inanç ve öğretiler, getirmiş oldukları ilke ve
prensiplerle yaşama bir düzen vermeyi amaçlamışlardır. Dinlerin, özellikle de
vahiy ekseninde teşekkül etmiş dinlerin bu bağlamda özel bir yeri vardır. Zira
dinler bütünüyle bu dünya yaşamına odaklanmakla kalmamış, daha ziyade burada
tesis ettiği düzen ve intizamla esas olarak insanın öte dünya hayatını
kurtarmayı amaçlamıştır.İnsanı ve onun aklını
otorite kabul eden, bu çerçevede bütünüyle dünya hayatına odaklanan modern yaklaşımlar
(insanı ve bu dünya hayatını önemsizleştirdiği gerekçesiyle) dini ve metafizik
içerikli tutumlara mesafeli durmuşlar, dahası onları reddetme yoluna
gitmişlerdir. İnsan yaşamını akıl ve tecrübeye indirgeyerek onun psikolojik
eğilimlerini dikkate almayan bu tutumlar, kendisine muhalif çok daha özgürlükçü
bir karakter sergileyen postmodern anlayışların doğmasına sebep olmuştur. Bu
makalenin temel amacı da, modern ve postmodern yaklaşımların din karşısındaki
tutumlarını felsefi bir tarzla eleştiri konusu yapmaktır.
