Progress of inert anodes in aluminium industry: review

Abstract: The paper is a review of the advancements achieved towards the research work done towards inert anodes for aluminium reduction cell. The research work dedicated towards inert anodes has been for more than a century, but significant advancement was made only a few decades ago. The aim of the researchers was to find the anode which shows excellent electrical conductivity and highly resistant towards corrosion with longer anodic lifetime but this is highly difficult to achieve. This article reviews the research work done on: (1) Ceramics, which are oxides of Ni, Sn, Fe, and Cu which can be one or a combination of oxides e.g. NiO − Li2O (2) Metals, in pure or alloy form (3) Cermets, oxides in combination with the metals. Some results obtained in laboratory scale cells were highly liable and gave a scope to try them on industrial cells.

Development of Themethod of Abies Wood Ethanollignin sulfonation Using Sulfamic acid

Abstract: The method of obtaining of water soluble sulfated lignin based on the treatment of ethanollignin of abies wood by sulfamic acid in 1,4-dioxane medium in the presence of basic catalyst urea was developed. The introduction of sulfate groups into the structure of lignin is confirmed by data of elemental analysis and IR-spectroscopy. The developed method of sulfated lignin synthesis is more simple and safe, than the known methods.

Determination of Chlorate and Perchlorate Ions in Drinking Water Using Capillary Electrophoresis

Abstract: In this study it is shown that the chromate background electrolyte suggested early by the authors is suitable for the determination of chlorate and perchlorate ions in drinking water using capillary electrophoresis. The analysis conditions were found allowing one to determine the ions with concentration lower 0.5 of maximum permissible values. The calibration curves were linear within the range of 0.01-0.1 mM with sample injection at pressure of 50 mbar for 100 s. The method validity was proved by the standard addition method. Using the developed method the real samples of drinking water of Krasnoyarsk were analyzed. Chlorate and perchlorate ions were not found in the sample studied.

Calculation Method for Evaluation of Solid Fuels Net Calorific Values on the Basis of Technical Analysis

Abstract: In the work the calculation method to define solid fuels net calorific values of woody biomass, peat, lignite, coal and anthracite on the basis of technical analysis, including the determination of total moisture content, ash content and yield of volatile substances, was developed. The method includes determining atomic relations of hydrogen to carbon and oxygen to carbon with subsequent estimation of elemental composition of the combustible matter and raw matter of solid fuels. Three variants for calculating relations of hydrogen to carbon and oxygen to carbon were considered. For sulfur content in solid fuels combustible matter less than 2 % wt. the standard deviation of estimated solid fuels net calorific values from literature data was 3.0÷3.4 % depending on the relations of hydrogen to carbon and oxygen to carbon calculation variant. For sulfur content in solid fuels combustible matter of 2.1÷8.4 % wt. the standard deviation of estimated solid fuels net calorific values from literature data was 4.7÷5.6 %. Such way of the using the technical analysis data to determine net calorific values of solid fuels may be useful in the absence of the elemental composition and solid fuels net calorific values, as well as to control characteristics of solid fuels in boilers.

The construction of cultural and religious identities in the temple architecture

Abstract: Cultural and religious identity is constructed in works of art. These processes will be considered in the example of Indian Islamic art. Religious art is representative of religions concept. Indian mausoleums, which were created during the reign of Mughal represent features of Indian Islam. Art analysis and philosophical interpretation of signs and images of Indian mausoleums helps to understand the unique features of Indian Islam. Religious Islamic art in India continues to have an impact on the recipients in the present. The art works of Islamic architecture can be studied as cultural texts. The ideals, values and standards of Islam are of architectural form. Indian Islam has unique cultural features. These cultural ideals, values and standards not set out in the treatises and books. Features of Indian Islam can be understood if we explore the features of Indian architecture of the Great Mughals’ Era. The Indian mausoleums are representing of unique qualities of Indian Islam of this historical period. The inside and outside interior of the Great Mughals’ mausoleums, as well as their environment, represent together the fact of achieving Heaven and the process itself, as well as the guide for people beholding the architecture, which would help to get in Heaven with grace of Allah. Indian mausoleums of the Great Mughals’ Era can well be called as architecture representatives of the Islamic religion. The cultural-semiotic analysis of these architectural sites shows. That its visualize basic principles of Islam, including hard way of man towards Allah together with Heaven’s achieving. The article presents a cultural-semiotic analysis of these architectural objects. It is proved that cultural and religious identities are constructed through the perception of architectural objects.

Poplar Forests of the Ob River Near the Town of Kolpashevo, Tomsk Region, Russia

Abstract: Natural poplar (Populus nigra, Populus alba) forests of the Ob River were studied on the northern border of south taiga subzone (vicinities of the town of Kolpashevo, Kolpashevo district of Tomsk Region, 58o18′ N, 82o54′ E) on the floodplain segment formed in 1890–1970. They belong to association Anemonidio dichotomi-Populetum nigrae Taran 1993 (Equiseto hyemalis-Populion nigrae Taran 1997, Salicetalia purpureae Moor 1958, Salicetea purpureae Moor 1958) and 2 subassociations: Anemonidio dichotomi-Populetum nigrae typicum Taran 1993 and Anemonidio dichotomi-Populetum nigrae rubetosum saxatilis Taran subass. nov. The poplar forests were examined from young timber stage of black poplar (Populus nigra) to stage of its total extinction. General direction of the poplar forest succession is expressing in a replacement of black poplar stands by birch ones. On sandy soils, black poplar stands are changed by small-sized Scotch pine ones. At the middle stages of the succession, white poplar (Populus alba) plays a significant role, occasionally along with Populus × canescens. However, white poplar doesn’t form stable stands near the town of Kolpashevo as it grows there at the northern border of its areal in Western Siberia. In studied poplar forests, the average species saturation was 42.4 and 14.4 species per 100 m2 for vascular plants and for mosses respectively. On the whole, 123 species of vascular plants and 34 species of mosses were registered in the poplar forests.

The State and Dynamics of Biological Communities in the Rybinsk Reservoir under Climate Changes

Abstract: The long-term data on structural characteristics of phytoplankton (1954–2014) and zooplankton (2004–2013), as well as chlorophyll content in the water and bottom sediments (2009–2014) in the Rybinsk Reservoir (Upper Volga, Russia) were analyzed. It was shown that the modern climate changes lead to transformation in the state and dynamics of biological communities that is characteristic of the trophicity increase. After the abnormally hot summer of 2010 a sharp rise in chlorophyll content in water with a predominance of values typical for eutrophic and highly eutrophic conditions was detected. Distribution of plant pigments in the bottom sediments was similar in different years, which shows the specific character of the sediment complex structure in the reservoir. In the seasonal dynamics of phytoplankton biomass and chlorophyll concentration the summer maximum caused by development of cyanobacteria began to dominate above the spring one. In the structure of phytoplankton the proportions of cyanobacteria and myxotrophic phytophagellates increased, the invasion of brackish-water diatoms was marked, and diminution of the cell size was noted. In seasonal dynamics of zooplankton biomass the second late peak was formed in August and it was particularly pronounced in the abnormally hot summer of 2010. In addition, there was a 1–2 week shift in timing of the beginning and ending in seasonal cycle of a number of zooplankton species relative to the 1960–1970s. Appearance of a summer dissolved oxygen deficiency (up to 1–4 mg O2/L in the layer of 1–7 m above the bottom) resulted in a local change in the vertical distribution of crustacean filtrators and decrease in their abundance up to three times.

Effect of a Porous Structure of the Carbon Sorbents from Abies Wood Lignin on Sorption of the Organic Substances of Different Nature

Abstract: Effect of porous structure of carbon sorbents, obtained by alkaline thermal activation of ethanol-lignin of abies wood,on the methylene blue and the vitamin B12 sorption was studied. It was sown that their sorption capacity for vitamin B12 depends on the content of mesopores with width 2,00–3,61 nm and formethylene blue – on the content of micropores with width 1,06 – 1,95 nm. The isotherms of sorption of the studied marker substances on sorbents with different porous structure were compared and their differences were discussed.

Principles and Opportunities of the Study of Pictorial Heritage in the Practice of Choreographic Education

Abstract: The article is dedicated to an underdeveloped, but highly relevant aspect of work of museums, first of all the theatrical ones, namely keeping, studying and promoting the works associated with choreographic heritage. The objective of the article is to analyse the artistic and aesthetic features of museum exhibits dedicated to dance, their specific features in the context of methods of their study by undergraduates of choreographic faculties, as well as their attribution to artistic culture. An analytical approach to understanding of a theatrical exposition and a ballet exhibit in the context of modern conceptual methods of its study is chosen as a methodological basis. The artistic and aesthetic potential of material and visual exhibits related to the ballet theatre is revealed. All the figurative and metaphoric world of dance involved in a particular exhibition project is considered from the standpoint of the main carrier of a theatrical idea at the level of its perception by a master of a theatrical university as a potential researcher. The material is structured in accordance with the main concepts of the article analysing the aspects of studying choreographic heritage in museum collections, the methodology of studying museum items in theatrical expositions, the role of museum pedagogy in the prospects for studying choreographic heritage. The proposed aspects of considering the monuments of choreographic heritage in the museum environment brings this problem to a qualitatively new level of conceptuality, justifies the possibility of separating the theory of their study into an independent scientific field that integrates into the modern theatrical museum studies as a new direction of interdisciplinary knowledge and is developed by means of various humanities.

Application of ISSR Markers to Assess Genetic State of Scorzonera glabra Rupr. (Asteraceae) from the Environs of Karabash (the Chelyabinsk Region)

Abstract: Genetic diversity of two local populations of the Ural endemic and the Pleistocene relict Scorzonera glabra Rupr. (Asteraceae) from the surroundings of Karabashskiy Copper-Smelting Plant (impact) and mountain Egosa (background) was studied using ISSR markers. The results show that the level of polymorphism is high in both populations. Analysis of molecular variance (AMOVA) show that the large portion of the variability (85 %) determines by intrapopulation one. There are no significant differences in genetic diversity among local populations. We suppose that S. glabra being a plastic species has pre-adaptations that allow it to grow under impact conditions.

Prediction of Physical-Chemical and Fire Hazard Characteristics by Carbon Chain Rules.1. Alkanals

Abstract: Investigations of the dependence of physico-chemical and fire hazard properties from the chemical structure of alkanals are carried out. Forecasting the boiling temperature, the flash point, the temperature and concentration flammability limits, the heats of combustion and vaporization is performed by the rules of the carbon chain. For the convenience of practical application of the rules of the carbon chain, the following empirical equations for the calculation of physico-chemical and fire hazard indices from the conventional carbon chain and from the number of carbon atoms are proposed. A comparative analysis of the proposed methods for calculating the flash point and the methods of GOST 12.1.044-89, Mendeleev and ACD/Lab 2014 is carried out. It is shown that the new methods basically give more accurate calculation results than the comparison design procedures.

Beyond the Polar Code: Enhancing Seafarer Safety along the Northern Sea Route

Abstract: Climate change is opening new sea routes in the Arctic Ocean. The Northern Sea Route (NSR), along Russia's Arctic shore, is particularly important in this regard. While in recent weeks some shipping companies have pledged to refrain from shipping through the Arctic, due to the environmental risks associated with doing so (and likely also due to limited profitability), the NSR is of crucial importance for the development of the Russian economy in the Arctic, in particular for the export of hydrocarbons to China. Therefore ship operations in the NSR will continue to be relevant for the foreseeable future. A reduction of sea ice cover in the Arctic Ocean as a result of climate change, however, does not necessarily mean that ship operations are without risk. The Polar Code was designed to tackle some of these dangers, but improving seafarer safety requires more. This article aims at raising awareness of both the dangers of Arctic ship operations and the legal tools available to enhance safety in the region.

The Kinetic Investigation and Optimization of the Processes of Larch Arabinogalactane Hydrolysis in the Presence of Dissolved and Solid Acid Catalysts

Abstract: The infl uence of the temperature and the reaction time of larch arabinogalactan (AG) hydrolysis in the presence of dissolved mineral acids H2SO4 and HCl, as well as solid acid catalysts Amberlyst 15, acid-modifi ed SBA-15 and Sibunit-4 on the rate of formation of arabinose and galactose was studied. The rate constants of monosaccharides formation are increased in the series of catalysts: Sibunit-4 (150 °C) < SBA-15 (150 °C) < Amberlyst 15 (150 °C) < 0,1M H2SO4 (130 °C) < 0,1M HCl (130 °C). The activation energy of the reaction of arabinose formation (65-91 kJ/mol) is lower than that of galactose (112-140 kJ /mol). The composition of soluble products of acid hydrolysis of arabinogalactan is studied by gas chromatography. The process of arabinogalactan hydrolysis in the presence of dissolved and solid acid catalysts was optimized by the calculation methods. The optimal parameters of processes at which a degree of arabinogalactan conversion close to 100 % are established.

Preparation of Phosphorus Organo-Mineral Fertilizers with Prolonged Action, Based on the Aspen Bark

Abstract: The method of preparation of phosphorus organo-mineral fertilizers with the increase resistanceto leaching of mineral componentsby waterbased on the impregnation of aspen bark by water solution of КН2РО4 and its transformation into low soluble compound Са(Н2РО4)2 was developed. The optimal condition of fertilizers preparation, ensuring minimum leaching of phosphates and potassium were selected. The possibility of enrichment of fertilizers by microelements (Mg, Cu, Zn, Fe) without the loss of their water resistance was shown. The increased resistanceof designed fertilizers on the basis of aspen bark to leaching of mineral components by water determines their prolonged action. As a result of vegetation growth experiments the stimulating effect of phosphateorgano-mineral fertilizers on the basis of aspen barkwas shown.

Diversity of fauna in Crimean hypersaline water bodies

Abstract: On the Crimean peninsula, there are more than 50 hypersaline water bodies, including the Sivash (the Sea of Azov), the largest hypersaline lagoon in the world. Based on the literature and our own long-term research data (2000–2017), a review of the fauna of the hypersaline waters in the Crimea is presented, including 298 species of animals belonging to 8 phyla, 14 classes and 27 orders. The variety of phyla and classes within a particular range of salinity was shown to decrease significantly with an increase in salinity; 8 classes in 3 phyla can withstand salinities above 100 g/L, and only 4 classes (Branchiopoda, Hexanauplia, Ostracoda and Insecta) within 1 phylum (Arthropoda) occur at salinities above 200 g/L. The number of species found in a single sample also decreased with increasing salinity. However, in the range of 50–120 g/L, the number of species was mainly determined by a different set of factors. The abundance of animals in the hypersaline waters of the Crimea can be very high: e.g., Nematoda – up to 1.4∙107 ind./m2, Harpacticoida – up to 3.5∙106 ind./m2, Ostracoda – up to 5.8∙105 ind./m2, and Moina salina – up to 1.3∙106 ind./m3. A characteristic feature of hypersaline water ecosystems is the fact that increases in salinity cause increasing amounts of benthic animals (Chironomidae, Harpacticoida, Ostracoda) to change their habitats from the bottom to the water column. At salinities above 120–150 g/L, there is almost no animal life at the bottom. Most of the species found in shallow hypersaline waters have a resting stage in their life cycle, which ensures their survival in abruptly changing environments, even those in ephemeral water bodies.

The Advance of Woody and Shrub Vegetation to the Mountains and Changes in the Composition of Tundra Communities (Poperechnaya Mountain, the Zigalga Mountain Range in the Southern Urals)

Abstract: Estimation of the dynamics of zonal and mountain tundra plant communities is extremely relevant in modern conditions of climate change. This article demonstrates the results of the estimation of woody and shrub vegetation progression to higher mountains at the Zigalga mountain range (the Southern Urals) using various methods: the comparison of aerial and satellite images, the repeated landscape photographs made at different times and also the examination of Juniperus sibirica Burgsd. age structure at different altitudes. The upward shift of woody and shrub vegetation is caused by the air temperature rise and increased precipitation during the winter periods in the Southern Urals. Vertical and horizontal upper limit shifts of open woodland from 1958 to 2012 are demonstrated. The vertical shift was determined to be 0.74 m/year and the horizontal one is 0.20 m/year. Based on the study of J. sibirica age structure, the fact of its advancement to the mountains during the last two centuries has been established. The research has been focused on the floristic composition of the mountain tundra communities with different J. sibirica cover. The floristic composition of the mountain tundra communities demonstrates their typological similarity. Introduction of J. sibirica leads to structural reorganization. The observed trends for vascular plants do not have any correlation with the height above sea level. Species composition of lichen synusia does not depend on J. sibirica cover, but it correlates with the altitude. Species richness and abundance of terrestrial lichens decrease in plant communities located lower on the mountain slope.

The Problematic Aspects of Cultural Policy in Modern Tuva

Abstract: The article is devoted to the analysis of the cultural politics in Tuva and is focused on the problematic aspects of its current development. It is the result of reflection on personal participation in the cultural policy making in the Tyva Republic, followed by the report and its subsequent discussion (within the Forum “Tuva of Future: Strategy for Change”, 28-30 June 2017, Kyzyl) through the application of historical-comparative, structural-typological and participant observation’s methods. According to the author, a major challenge for the development of culture industry of Tuva is that in the Soviet period it was the institutional model chosen for regional cultural development, while the region experiences the lack of human resources. Ethnic culture of the post-Soviet stage in the Tuvan history is characterized by the self-isolation concerning the value aspect. The implementation of the cluster institutional models and the effective use of the Tuva cultural brand, which is an eco-exo-ethnocultural synthesis, can contribute to the solution of the cultural policy problems. The research results can be applied in the development of concepts and Republican target programs of the Tuva cultural development. The prospect may be finding the optimal balance of conservative and innovative tendencies. The imbalance between ethnic culture and national culture in the contemporary cultural life of the Republic should be oriented towards the national (Russian) identity and its understanding.
