Published: November 2019

Koi fish (Cyprinus carpio) is one of the ornamental fish of a high economic value. However, raising koi can be troublesome due to poor water quality and high levels of stress that they are attacked easily by parasites. One of the parasites often attacking the gill of koi is Myxobolus sp. The presence of Myxobolus sp. can be observed through a histopathological observation of gill tissues. The purpose of this study was to determine the histological effect of probiotic administration to the damage on the gill tissue of Koi fish (Cyprinus carpio) infected with Myxobolus sp. The method used in this study was an explorative experimental method using factorial RAL. The observation of gill tissue was carried out on samples of koi fish consisting of two (2) control treatments, namely positive control (K+) and negative control (K-). Then, six (6) treatments, consisting of fish infected with Myxobolus and healthy fish, were done by applying a dose treatment of 1.1 ml/30 litters of water, 0.55 ml/30 litters of water, and 1.65 ml/30 litters of water. Treatments on control groups were carried out in a controlled tank by maintaining water quality parameters, which include temperature, pH, DO, and CO2. The level of gill tissue damage treated with probiotic formulations was determined by scoring analysis. The results of histopathological observations commonly showed tissue damage, namely damage to Edema, Hyperplasia, and Lamela Fusion. The treatment having the best influence according to the 5% BNT test was the PB treatment (infected fish with a dose of probiotic formulation of 0.55 ml/30l).

Published: November 2019

Indonesia is a country that has a great concern over achievement of SDGs 2030 global agendas. As a big country in terms of population and area, but unfortunately has the most population of lower-middle income, it would be very interesting to examine the process and substance of sustainable development planning in Indonesia. This study uses two methods, i.e., content analysis towards medium-term planning and interview with the planners. Result of Mid-Term Development Plan (RJPMN) 2010-2014, RPJMN 2015-2019 and Action Plan for SDGs Achievement review show that Indonesia applies strategic planning approach as its framework planning of sustainable development which started with the formulation of sustainable development strategic issues, a mission statement, strategies, programs, action plans, targets, and indicators of achievement. This approach has not been reliable yet to address the challenges of interrelated sustainable development. Although the result of interview informs that Indonesian government strives to keep improving the planning process through the increasing involvement and participation of development stakeholders, a paradigm shift is still required to answer all challenges of sustainable development by performing more intensive education.

Published: November 2019

The Soyots (indigenous minorities) live in a remote mountainous area of the Baikal region within the limits of the Okinsky District, the Republic of Buryatia. The main type of economic activities of the soyots is the traditional use of natural resources. In this study, we have carried out economic and geographical analysis of the spatial organization of economic activity of the Soyots on the Eastern Sayan territory. Some researchers consider that the traditional use of natural resources by indigenous people is a vulnerable social and economic system, which requires state support and cautious attitude. Traditional farming and traditional lifestyle are the indispensable living conditions for indigenous people. The possibility of their survival and development in modern conditions is an important problem to be addressed. The study of the current form of the traditional use of natural resources is a priority and needs to be analysed, considering modern social and economic conditions. In a time of industrialization, large-scale development of natural resources of the Eastern Sayan resulted in disturbance of such territories. The Government of the Republic of Buryatia and administration of the Okinsky District have important tasks to preserve the unique area, where the Buryat and Soyot ethnic groups live and create conditions for rational use of natural resources. Unique climatic conditions in the Okinsky District are suitable for both reindeer breeding and cattle farming. The analysis of ethno-economic systems has revealed the areas characterized by the traditional use of natural resources and its spatial-temporal aspects on the Eastern Sayan territory.

Authors: Beshentsev A N , Borisova T A
Published: November 2019

The article contains data on catastrophic floods on the rivers of Lake Baikal basin in the past century. It describes the functional structure of the GIS of flood monitoring. The study justifies the advantage of the basin approach in flood assessment and mapping. We determine the basic regional climatic and physico-geographical factors of flood formation and characterize the main indicators of the territory danger from floods: frequency, magnitude and extent of floods. As hydrological information, we used the calculated water levels in the sections obtained from annual probability distribution curves of exceeding the maximum water levels from rainfall floods. The flood indicator is calculated as the difference of the maximum rise in the water level above the critical level of water outflow to the floodplain. Calculation data show that the maximum values of water levels in the basin’s rivers are the most characteristic of the summer flood period. We have determined physico-geographical features of flood distribution on the main rivers of the study area, performed geoinformation mapping of flood parameters within the main river basins and described the technique of interactive work with GIS through geoinformation queries as well as characterized the response models of the hazard development.

Published: November 2019

The human-land system is a complex and open giant system composed of two subsystems of geographical environment and human activities. Though the optimization of the relationship between two subsystems, we could realize the regional sustainable development. The regional sustainable development is the embodiment of the most optimization of human-land system. This paper revealed human-land system, in terms of connotation, structure, relation, mechanism and function. Based on the theory of human-land system, the paper proposed the regional sustainable development assessment model and carried out the empirical analysis in the township scale. We chose Haiyong Town as the study area. The results show that the study area is in a good level of regional sustainable development, but in a primary stage. The economic sub-system and the society sub-system have reached the good level of sustainable development, but the environment subsystem is always at a low level. The study area should put forward optimization strategies within the economic, social and environmental subsystems, such as ecological agriculture strategy, circular economy strategy, modern service industry strategy, environmental protection system strategy and so on, in order to promoting regional sustainable development. The research results can provide scientific reference for the assessment of regional sustainable development and the formulation of regional sustainable development strategy.

Published: November 2019

In the modern world, urbanization processes are becoming more and more intense, and the number of cities and their size are steadily increasing. The specific character of the country is quite well reflected in the geography of Russian cities, i. e. the large dimensions of space, a consistent approach to formation of the State territory, and the course of urbanization. The regions of the RF differ from one another by the degree of development, the level of socioeconomic advancement and matureness of the systems of cities, and by the spatial pattern of population distribution. Nowadays, the prospects for formation and development of large urban agglomerations (UAs) of Siberia are generating great interest. The characteristics of development of agglomerations in Siberia are considered. Based on analyzing the demographic processes and the existing population distribution pattern, an assessment is made of the problems and prospects of formation of agglomerations in Siberia.
Landscape hydrological principles for planning the water protection zone of Lake Baikal: aims and results
Authors: Gagarinova O V
Published: November 2019

The article presents the aims and objectives of the water protection zoning of the Lake Baikal coast as well as the main points of the landscape hydrological substantiation of the dimensions for the water protection zone of this water body, which is a World Natural Heritage site. Analysis of the legislative framework as well as current natural and ecological state of the coastal area indicate serious anthropogenic impacts on the lake and the lack of the water protection experience, especially, in residential and recreational areas. The study considers the main landscape hydrological parameters and criteria for determining the boundary of the water protection zone as well as physiographical conditions and the ecological necessity to include certain types of landscapes in the protection zone. The individual hydrological characteristics of landscapes, depending on the structural components, determine water potential and water protection parameters of the area, which allows for the substantiation of the water protection zone dimensions that ensure the protection of the water resources of Lake Baikal. The problems of water resources protection in the areas of economic use are of special attention. The study suggests the approaches to functional water protection zoning of urbanized and recreational areas, including landscape hydrological principles for assessing the area and methodological elements of landscape planning as well as regulation of the natural resources use for the purposes of the ecological development of coastal areas. A scientifically grounded water protection zone of Baikal involves coordination and control of all activities related to the use and protection of the lake.

Published: November 2019

Currently, many countries of the world experience drinking water scarcity. In this aspect, Russia has an advantageous position, having on its territory Lake Baikal, the largest storage of fresh water. UNESCO declared Lake Baikal as a World Heritage Site whose state scientists from Russia and other countries monitor and study. An analysis of the literature and the author information about the Baikal aquatic ecosystem has shown 70-year invariability of macroelement water composition of Lake Baikal and its only outflow, the Angara River. The water of Baikal and the Angara River has a constant calcium bicarbonate composition and is saturated with oxygen, 10-14 mg/l or rarely more. The average mineralization of water in Baikal and the Angara source for the study period (1950-2018 and 1997-2018) is 95-97 (87-112) mg/l. The analysis of the 13-year (2006-2018) data on the trace element concentration in the Angara source has revealed a complex pattern of changes in concentrations of some elements. The time trends of the concentrations for the bulk of elements sometimes indicate abnormal (minimum-maximum) concentrations regardless of the season. This can be only due to “one-time or instantaneous” natural or anthropogenic changes in the Baikal environment. The Baikal tributaries indicate different chemical composition, which can be due to not only drainage of rocks with different content but also the anthropogenic impact. A simultaneous testing of water (during a month) has shown that some macro- and trace elements (F-, HCO3
- and SO4
2-, as well as Li, Mo, B, U, Fe, etc.) have at the same time the similar concentrations in the water from Baikal, the Angara source and most tributaries.
Anthropogenic impact of industrial production on the environment (on the example of the Siberian region)
Authors: Ippolitova N A
Published: November 2019

The anthropogenic impact of industry on the environment depends on the nature of its territorial localization, extraction volumes and raw material and energy consumption, on recycling and the extent of production cycles. As a result of environmental and geographical studies, we identified industry sectors, as well as industrial facilities, that have the most negative impact on the environment and the livelihoods of the population. As a rule, industrial facilities are located extremely unevenly in the territory of the region, they are concentrated in cities and large settlements, and have a significant negative impact not only on the environment, but also create an uncomfortable living environment for the population. Areas of technogenic pollution with an extremely tense environmental situation, which enhances the natural discomfort of the living environment and worsens the quality of life of the population, have been identified. Special attention is paid to industrial facilities that have ceased their production activities, but continue to have a strong anthropogenic impact on the environment, because the disposal of industrial waste creates a tense ecological situation and poses a threat to the environment and the population.
Anthropogenic Load on Transboundary Geosystems of Altai: Current State and Trends
Authors: Karanin A V , Minaev A I , Sukhova M G , Zhuravleva O V , Babin V G
Published: November 2019

Transboundary areas of the Altai Republic are notable for great diversity and vulnerability of natural complexes. Residential landscapes have one of the highest levels of anthropogenic transformation among the geosystems of the transboundary territories of the Altai Republic. Vacationing people, whose number is increasing every year, also have a significant impact on the environment. We have determined the percentage ratio of residential areas to the landscape area of their location to estimate the residential load. As a major criterion for assessing the recreational load, we propose to use the number of bed spaces for seasonal and year-round recreation at campsites, campgrounds, and hotels. As another criterion reflecting the impact of recreationists on the natural-territorial complexes of the studied areas, we consider the density of the tourist route network to the square kilometer of the landscape. The study has shown that the residential load on the landscapes in the transboundary areas of the Altai Republic is relatively low. Intermountain valley landscapes are the most loaded (up to 4.5% of the landscape area). The human impact on the high-mountain and mid-mountain landscapes is insignificant.
International water development problems in the transboundary Irtysh River basin: “new” solutions to old problems
Authors: Krasnoyarova B A , Vinokurov Y I , Antyufeeva T V
Published: November 2019

The article discusses the problems of water use in the transboundary Irtysh River basin and the characteristics of their manifestation in different national segments. In the basin countries, separate subsystems are distinguished by the nature of the formation and use of water resources. There is a growing position of the Chinese side; it has significantly increased the withdrawal of water resources from Kara-Irtysh, thereby, violating the state of the aquatic ecosystem of the receiving Lake Zaisan and, accordingly, the operation of the Upper Irtysh reservoirs and hydroelectric power plants. In the Russian Federation, the situation is the most complicated in the Tobol River basin, where large industrial centers of the Trans-Urals are located; in Kazakhstan − in the Ishim river basin due to a significant development of its capital Astana (Nur-Sultan). We have analyzed the largest projects on the Ob water transfer to the Irtysh river basin proposed by the Chinese and Kazakh scientists and designers. The Russian side had a somewhat passive role in this process, which focuses mainly on solving specific problems, in particular, providing water resources to the city of Omsk through the construction of the Krasnogorodsk water reservoir at the Irtysh and the inter-basin transfer of river water from the Urals, Kama and Irtysh to the Tobol River basin. Emphasis is placed on the need to establish tripartite institutions for regulating water relations and international cooperation in the field of water use in the Irtysh river basin.

Authors: Kravchenko V V , Kichigina N V , Yu Opekunova M
Published: November 2019

The article presents the vertical channel deformations assessment (erosion of the riverbed bottom or accumulation of sediment) on the rivers of the Angara region. Channel processes are wide-spread here due to geomorphological and hydrological features of the territory. Vertical channel deformations are a change in the river bottom altitude under the water flow, sediment transport and accumulation. An important indicator of the dynamics of channel deformations is the changes of the water level and discharge. The Q = f (H) curve is one of the most important characteristics of the river’s water regime and bed morphometry. The direction and speed of the vertical channel deformations were determined by analysing the curves of the water level changes at a fixed discharge. The average of the annual maxima discharge is chosen as the fixed discharge. As a result, the sections of the rivers with erosion of the riverbed bottom, sections with a predominance of sediment accumulation, as well astable sections of the riverbed have been identified. The identified trends of the vertical channel deformations were verified by constructing of cross-section channel profiles according to depth measurements for the period 1997-2017.Moreover, the imposition of multi-temporal cross-section channel pro-files revealed not only vertical, but also horizontal deformations.

Application of landscape planning approach for study of peculiarities of territorial organization and territorial development
Authors: Myadzelets A V
Published: November 2019

Forming of economic-geographical environment for innovative development is closely related to landscape and resource characteristics of a territory. It is revealed through a system of related characteristics that should geographically fully and accurate describe the nature, economy and population of the territory and express its state through a special assessment indication function of all natural and economic factors. Such task is solved on empirical data and the principles of the geosystem theory by Sochava, indicative and landscape planning approach, methods of interpretation mapping, comparative geographical analysis, geoinformation and math modeling. A landscape typological map is considered as an invariant basis for the analysis of the territory, reflecting the spatial distribution of geosystems of different types and allowing to derive new knowledge and create thematic maps of different content for solving applied problems. Features of the geographical environment and its impact are taken into account through the introduction of quantitative environmental corrections using the methodology of polisystematic stratification. A unified database with a grid of natural and economic units of the landscape map is created for the area of the Selenga river delta for analysis of the territorial organization peculiarities and local development. The assessment indication function is calculated on the geosystem database and characterizes the features of the territorial organization with the definition of individual indicators of economic development for each unit of the study area.

Air temperature is one of the most important climate characteristics, which is used for climate research, investigation and modeling of vegetation, hydrological parameters and other landscape components as well as geosystems entirely. The use of a landscape approach greatly simplifies the process of visualizing meteorological parameters and allows you to take into account influencing factors, since they have already been taken into account when drawing up a landscape map. This article describes cartographic models of the air temperature field of the Tunka intermountain basin created using in-situ wide network of modern automatic measuring instruments and remote sensing methods that allow us to solve the problem of climate research at a local level, as well as a landscape-interpretation mapping method. The main advantages and disadvantages of these cartographic methods are assessed. It is shown that a joint analysis of the data from a dense network of field observations, remote sensing data, and a landscape map made it possible to analyze the dynamics of the spatiotemporal distribution of the air temperature field with a relatively high degree of accuracy.
Preservation of the natural potential of vegetation. Assessment in landscape planning
Authors: Novitskaya N I , Suvorov E G
Published: November 2019

The priority purpose of landscape planning is preservation of natural environment with existing ecosystem interrelations under prevailing conditions for the territory development. Analysis of the contemporary state of plant cover is component part of the comprehensive program of studies on landscape planning, which reveals dynamics of vegetation, territorial differentiation, biological variety, degree of territory disturbance communities, and potential of their preservation. Natural stability of vegetation, which is supported not only at the level of biocenosis, but also at the level of spatial current connections of contemporary landscape, is one of the main conditions of preserving the biotope structure. Particularities of development and nature restoration determine ecologically favorable conditions of existence and renewal of plant cover structure. External disturbing factors set additional constraints on the motion of natural dynamics, slowing down restoration or completely leading to irreversible changes. The evaluation of sustainability of plant communities for the southern part of the Lake Baikal coast was carried out on the basis of expert estimation for multifactoral impacts upon dynamics and was represented using a cartographic method in the form of integrated areas of the sustainability of plant communities. Cartographic interpretation of contemporary vegetation state of investigated territory, the determining of the integrated areas of plant community’s sustainability, and further sequential carrying out of interconnected estimation maps, makes possible to differentiate territory in the categories of landscape planning for the complex preservation of natural environment and to develop the necessary measures for stabilization.

Published: November 2019

The article presents data on continuous monitoring of the characteristics of the climate system with high spatial-temporal resolution. The study area is the Tunkinskaya rift system of depressions, in particular, the Tunkinskaya and the Mondinskaya depressions. Five cross sections characterizing the typical conditions of mountain-depression landscapes of the South Baikal region were selected. At each point of a cross section, a description of the landscape, laying of the soil section, its description, sampling for subsequent laboratory analyses to clarify the genesis and name were carried out. Meteorological parameters were monitored using stand-alone programmable thermographs. It was shown that the influence of individual and contrasting morphometric characteristics of depressions on the climate is reflected in the characteristics of the temperature and humidity regime as a whole, as well as in the features of the cold and warm period. There is a high spatial heterogeneity of temperatures and precipitation with a noticeable gradient between the peripheral and central parts of depressions. It is also shown that the territory is characterized by the high contrast of geological, geomorphological, phytocenotic and soil conditions, which creates a unique landscape diversity both between different depressions and within each depression.

Effect of a gas-vortex stabilization method on the kinematic properties of the jet in metal-cutting plasmatrons
Authors: Anakhov S V , Matushkin A V , Pyckin Yu A
Published: November 2019

Various methods of gas-vortex stabilization in plasma cutting torches are investigated. The results of the study demonstrate the dependence of the angle of gas injection into the nozzle on the kinematic and kinetic characteristics of plasma jet and, consequently, on the cutting parameters. Increased radial velocity component at the swirler output provides better uniformity of the velocity distribution and kinetic properties of the jet in the affected zone of a cut metal. As a conclusion, it is recommended to use the suggested narrow-jet-plasma technology for cutting thin sheet metals.

Published: November 2019

The paper presents the results of an experimental numerical study of the stress state of the rods of a flat truss and the results of the analytical calculation. The values of internal forces and stresses in the truss model were obtained using the SCAD software package, as well as experimentally using the polarization-optical method. The finite element method (FEM) is used to calculate two plane truss models. In the first case, the truss was modeled by rod elements, in the second – by plates. The fields of normal, tangential and principal stresses are obtained. With their help there were found the longitudinal internal forces in the rods of the farm. The interference bands in the model of a flat truss are obtained by the method of photoelasticity. Stresses are calculated with their help. The quantitative and qualitative analysis of the stress state, described in the numerical and physical experiment, is carried out.

Published: November 2019

The structure, phase composition of the composite electroexplosion coating of ZnO- Ag system subjected to the irradiation by the high intense electron beam have been studied for the first time. The combined processing including the electroexplosion spraying of the coating of ZnO-Ag system and its subsequent electron beam processing results in the formation of multilayer structure of the coating. The electron beam melts and homogenizes the surface layer of the composite electroexplosion coating of ZnO-Ag system to the depth of 35-40 μm. The effect of the electron beam leads to the formation of the nanocrystalline phases of Ag, ZnO, Cu, CuZn, Ag5Zn8, Cu2O, Ag2O, Cu0.67Zn0.33, AgZn. The dependences of changes in crystal lattice parameters and coherent scattering regions of the phases being formed depending on the processing regime by high intense electron beam have been found.

Authors: Stanica D I , Dumitriu M
Published: November 2019

Ride comfort is one of the criteria for evaluating the dynamic behaviour in railway vehicles, through which the complex sensation triggered by the vibrations in the railway vehicle carbody upon passengers is being described. The behaviour of vibrations along the vehicle carbody is not uniform and the point where the ride comfort is the least convenient can be considered as the carbody critical point. The paper examines the ride comfort along the carbody and the position of the ride comfort critical points in correlation with the speed, carbody flexibility and suspension damping. To this purpose, there are used the results from numerical simulations regarding the ride comfort index calculated along the carbody and the ride comfort index in three points deemed relevant in terms of evaluating the ride comfort at the center of carbody and above the bogies.
