Authors: Nguyet L M , Minh D Q , Lan P T H 
Published: June 2019

Abstract
In this study, a method for developing a quantitative prediction of river bank erosion in Bien Hoa district in Dong Nai River is presented. The river bank erosion hazard index (BEHI) was estimated to assess the stability of the river bank erosion in consultation with bank height, bank slope, rooting depth, rooting density and surface protection. The estimated BEHI of Dong Nai River in Bien Hoa district are high which indicates the riverbank instability. The estimated BEHI along the left bank is about 25-30. The satellite data of LANSAT TM 5, LANDSAT ETM 7 for the year 1995, 2005 and 2015 were used to assess the nature of shifting of the river bank and to estimate the land loss from river bank. All the derived images were transported on GIS environment to extract the course of the river. 13 sites were considered along the Dong Nai River in Bien Hoa District to estimate the leftward shifting of the bank line and to assess the shifting distance of the river bank line. There is a strong relationship between bank instability BEHI, shifting distance of the bank line and eroded bank area in this study.

Published: June 2019

Abstract
Results are presented of the comparative analysis of frequency of erythroid cells with micronuclei and “tailed” nuclei and of the interphase nuclei indices of red blood cells in the peripheral blood of bester, a sturgeon hybrid. The differences are found in the frequency of occurrence of abnormal red blood cells between the two groups of fish kept in cages in natural water (river) and in ponds with water supplied through a sedimentation basin. Despite these differences, the number of erythrocytes with chromosomal abnormalities in the bester of both groups is close to normal. However, the number of erythroid cells with micronuclei and “tailed nuclei” prevailed in the fish held in river cages. It was suggested that comparative cytogenetic monitoring of fish can be used not only to characterize the environment of water bodies, but also promote the rational organization of artificial reproduction of aquatic organisms that would contribute to the conservation of biodiversity of aquatic biological resources.

Abstract
An analysis is made on the influence of factors on the implementation of integration processes in the transport sector. The problems of an estimation of the level of the transportation capacities of the Eurasian Economic Union transport systems for transit freight traffic are considered, taking into account their unevenness in directions. Modern research does not pay enough attention to improving the efficiency of transit traffic in the Eurasian Economic Union countries, taking into account the unevenness of freight flows. Insufficient scientific study of these issues determines the relevance of the study. Methodical bases are developed for integration of transit traffic of the Eurasian economic union countries by creating transit terminal complexes providing decrease in unproductive usage of transit transport. Expressions were obtained for estimating the excess transit transportation capacities of the Eurasian Economic Union transport systems and for assessing the effect resulting from the integration of freight flows in terminal complexes. The coefficient of unevenness in the directions of the region’s freight traffic with all adjacent regions, implemented through a transit transport hub, has been developed. The methodological bases for the integration of transit traffic are oriented at practical application. The results of the study can be used in the activities of transport organizations of the Eurasian Economic Union countries to improve the efficiency of transit transport and optimize the operation of terminal complexes.
Change in Rheological Properties of Liquid Multicomponent Systems, Including Hydrocarbon Fuel by the Addition of Nanomaterials
Authors: Zvereva E R , Makarova A O , Zueva O S 
Published: June 2019

Abstract
The addition of nanostructures leads to a radical transformation of the properties of traditional materials, practically without changing their chemical composition, only due to the tendency of molecules to appearance of the ordered structures and, as a consequence, to a change in functional characteristics of the original materials. Structural ordering of atoms around nanoparticles can lead to a change in viscosity and can be used to reduce the material intensity, the energy intensity, the labor intensity and the cost of production in technological processes. Thus methods and materials of nanotechnology can be used to create a composite hydrocarbon fuel with improved rheological characteristics. To reduce the viscosity of various types of hydrocarbon fuel, small amounts of nanoparticles can be added leading to an additional structure formation which may result in a change in rheological properties due to transition to layerwise shear flow. The possibilities of using carbon nanotubes and dehydrated carbonate sludge of water treatment were analyzed. The presence of a synergistic effect in the joint application of carbon nanotubes with carbonate sludge has been established. It has been shown that the choice of corresponding nanoparticles and their dispersion medium for a particular type of hydrocarbon fuel can significantly improve its rheological characteristics.

Published: June 2019

Abstract
This article presents the measurements of delayed fluorescence from Pinus sylvestris leaves against the functional load on the urban territory. We compare the values obtained with the results of chemical and analytical studies of the soil quality. The sampling was carried out according to a spatial grid designed on the basis of the functional load on the territory. The bioindication method as well as chemical and analytical tests of plant and soil samples taken at each site under study allow to differentiate these locations according to their ecological conditions. We made attempts to assess the degree of influence of various factors on some indicators of plant vitality. Calculations of the correlation coefficient between the content of a number of components in the soil and bioindication data suggest that the photosynthetic activity of plants in urban conditions is more dependent on the state of the atmosphere.

Abstract
The paper presents the results of scientific researches in the field of biomembrane treatment of dairy products industry enterprises wastewater. Practical experiments confirmed the possibility of reducing the inhibition degree of the process of biological treatment of dairy products industry wastewater, which has been physically and chemically purified, by increasing the concentration of active sludge. This effect can be achieved while using membrane bioreactor technology (MBR). The experiments also showed that if dairy plants wastewater is pre-treated with coagulants and flocculants, specific speed of biocontamination oxidation decreases in 1, 2-2, 3 times at BODfull = 250 mg/l in comparison with the initial wastewater. It happens because of substrate inhibition rate of biochemical reactions. The identified dependencies show that it is advisable to exclude the stage of reagent flotation before the biological treatment of dairy products industry wastewater. It can reduce costs of using a large number of expensive reagents and simplify the technological scheme. During the experiments dairy plants wastewater was taken as a model. Later, the researchers used real wastewater and confirmed the main kinetic constants and coefficients for calculations of biological purification plants. These results are as follows: temperature constant χ, grad−1, for aerobic heterotrophic conversion – 0,079-0,091, for nitrification – 0.096; for denitrification – 0.13. Coefficients of inhibition by active sludge φ metabolic products amounted to (l/g): for organic substances oxidation by BODfull – 0,39-0,54; for nitrification – 0.19, for denitrification – 0.22; active reaction of the environment corresponding to the highest rate of oxidation of organic substances pHopt – 6.9 at pH-constant 150. The maximum specific speed of organic substances oxidation r’max is 82,5-101,1 mg/(g × h), the Michaelis constant Km – 15 mg/l. The maximum specific speed of nitrification r’max is 1.49 mg/(g × h), the Michaelis constant Km is 0.12 mg/l, the constant of inhibition a is 43. The maximum specific speed of denitrification r’max is 10.8 mg/(g × h), the Michaelis constant Km is 3.5 mg/l. The calculated values of kinetic coefficients and constants make it possible to calculate membrane bioreactors of sewage treatment plants of dairy industry to the specified degree of purification. The estimated annual economic effect for “Pestravskiy” diary plant of the Samara region equaled 4 mln. rub/year (at 2017 values).

Abstract
The effluent treatment process for dairy waste water adopts physicochemical methods with adsorption playing a significant role in removing organic chemical contaminants. Corn waste, due to their abundance and large volumes, often attract the attention of environmental researchers. It is known that corn is an effective sorbent in the purification of aqueous media from oil products and dyes. In this work, there are researches of the physical and chemical characteristics of aqueous media treatment process from the components that are the part of the drainage of milk processing plants (lactic acid and asparagine) with ground thermal modified corn waste. It has been established that the obtained sorption material effectively extracts various components of sewage from milk processing plants. Extraction of asparagine occurs more efficiently than lactic acid, so for the amino acid, 91% efficiency is achieved, for lactic acid 78%. When the amount of pollutant in the range of COD values 305–320 mgO/dm3, the rational weight of the sorption material additive is 6 g/dm3.

Published: June 2019

Abstract
The basis of an urban ornitotsenoz is formed by several synanthropic mass bird species whose numbers are hundreds of times larger than the small and rare species. The vital activity of mass species leads to undesirable consequences for humans, reduces the biological diversity of ornithocene. Populations of synanthropic birds are reservoir and source of pathogens of dangerous zoonoses and zooantroponoses. The contact between the bird and the man takes place in the places of their accumulation: at transport stops, in parks and feeding places. To identify the percentage of patients with chlamydia rock pigeons in the city of Kazan were investigated in the serum and the pathological material of pigeons that live in different parts of the city. By managing the factors influencing on magnitude of population it is necessary to increase stability of a city ornitotsenoz. The stability of the urban ornithocenosis is a necessary condition for a healthy environment.

Published: June 2019

Abstract
The paper presents an overview of the studies of Russian and foreign scientists exploring the issues of reliable operation of trunk pipelines transporting oil and gas. It is found that subsea pipeline networks pose a greater danger in terms of their functional failures and environmental effects and appear more prone to stress corrosion cracking. Certain materials and technologies are brought into focus to demonstrate that their use allows curbing the environmental expansion or ensures the reliable operation of oil and gas pipelines. It is noted that one of the most promising methods for reconstruction and overhaul of trunk pipelines provide for the application of composite materials to the internal surface of a damaged pipes. The appropriate formulation of composite materials depends on the condition of the internal pipeline cavity. Also, there are scientific breakthroughs which may serve to reduce corrosion activity of clayey soils. Stress is laid on the importance of innovations in the development of technologies and materials ensuring the maintenance of ecological balance in the areas where oil and gas transmission networks operate.

Abstract
Currently the China’s Belt and Road Initiative (BRI) attracts the attention of the rest of the world. Two transport corridors, the sea and the land routes, will link China with Europe. For Russia the transportation component of the BRI has gained special significance, because it will allow to unlock the export and transit potential of Russian economy. The eastern transport corridor crossing Transbaikalia is a very interesting project for the Trans-Baikal Territory. One of the priority directions of this project is the possible building of a high-speed railway (HSR). The study purpose is the assessment of the impact of HSR building on the regional landscapes in the context of a) identification and evaluation of risks of loss for the most valuable natural areas and b) necessity of inclusion of these areas in the existing network of natural protected areas. The spatial analysis performed using GIS technologies shows that the HSR project will affect 35% of diversity of the regional landscapes. Fragile natural complexes were revealed among them. Moreover, the greatest impact can be asserted on the “Dzeren Valley” Federal Reserve, a part of natural complexes of which will be covered by the 10-km impact zone. The measures to mitigate and to compensate the negative impact of the new transport infrastructure on the regional geosystems are suggested.

Abstract
The coal deposits containing a complex of the major valuable microelements which have various degree of study are disclosed in Transbaikal territory. The analysis of geological material on coal deposits of Transbaikal region demonstrates great prospect for search and surveying of germanium-bearing coals in this territory. Gallium and beryllium at infrequent elements’ group is expedient to consider which are contained in local coals in the increased concentration connected among themselves. Content of these elements in coals it is caused by space exposure of coal and rare-metal deposits. The last include the production reserves of beryllium and they are a part of the Transbaikal region beryllium-bearing province in Russia. It is noted that some coal deposits of Transbaikal region have the increased content of rare-earth elements. Noble metals in the increased concentration are established in many assay of coal of various deposits that is caused by constant aurum content within the Transbaikal metallogenic province. There are data on content of valuable ore elements in coal deposits of the Transbaikal region, regularities of their placement depending on geochemical features of metallogenic provinces, conditions of accumulation and to form into various components of coals and also information about ore elements’ localization and their associations. The analysis of these data gives geological and technological characteristic to metal-bearing coals as to perspective complex of mineral raw materials. There are considered infrequent and diffuse elements, non-ferrous, noble, rare-earth and radioactive metals with concentration less than 0,1% as microelements in coals. According to the International Organization for Standardization 84 elements are detected in coals which belong to various groups of a periodic system of elements. 35-40 elements are found stably in coals of deposits of Russia in detection limits of mass analyses.
