Sufficiency of Investments in Environmental Policy of Mining Region
Authors: Starikova Ludmila , Trapeznikova Irina
Published: June 2018

Since 2005, expenditures on research, development and technological work (R & D) have been allocated in the structure of investments in non-financial assets. The absence of methodological developments on a comprehensive analysis of indicators of environmental and economic efficiency does not allow us to clearly determine the real costs of creating a system of rational nature use and environmental protection. In order to, at least approximately estimate the necessary level of investment in the restoration of the environment, it is necessary to conduct a study of the relationship between investment and environmental activities through the interrelationship between the concepts of "investment" and "capital investments".

Legal Support of Environmental Safety as a Reaction of the Russian State to Environmental Threats
Authors: Vorontsova Elena , Vorontsov Andrey , Drozdenkko Yuriy
Published: June 2018

The article is a comprehensive study of the problems of legal provision of environmental safety in the Russian Federation. The work of the authors was built taking into account the insufficient formation of the legal institution of environmental safety in Russian environmental law. This necessitated the use of an interdisciplinary approach, which allows us to fully consecrate the issues studied. The authors draw attention to the fact that initially environmental safety was not considered by Russian legislators and scientists as an integral part of national safety. The authors conclude that the inclusion of measures designed to ensure environmental safety in a single system for ensuring national safety should contribute to their improvement and development, since they are now becoming a priority. At the same time, the authors note the problem of the terminological inconsistency of the main strategic documents in this area - the National Safety Strategy of the Russian Federation and the Strategy of Ecological Safety of the Russian Federation for the period up to 2025, which, in their opinion, may negatively affect the effectiveness of legal support for environmental safety in Russia.

Development of Interrelated Voltage Regulation System for Coal Mines Energy Efficiency Improving
Authors: Nepsha Fedor , Belyaevsky Roman
Published: June 2018

In this paper, the authors propose an algorithm for interrelated voltage regulation in the power supply system of coal mine which allows to provide a normative voltage level and to minimize the level of active power consumption. A feature of the proposed algorithm is a separate consideration of discrete and nondiscrete variables. Nondiscrete variables are represented as a state matrix. The optimization of nondiscrete variables is performed for each state. The algorithm chooses a state with the minimal active power consumption. The obtained values of discrete and nondiscrete variables are transferred in the form of control signals to voltage regulation devices. In this case, the periodicity of the switching is determined by the resource of the on-load tap-changing device. The use of this algorithm will theoretically allow increasing the energy efficiency of power supply systems of coal mines.

Published: June 2018

The concept of sustainable development in comparison with other paradigms was the most acceptable, from the point of view of determining the development strategy of society, in the medium and long term. Due to that, such important trends in science and practice as the restructuring and modernization of the economy, energy efficiency, environmental security, "green economy", etc. have been developed. One of the most important areas of research, important both for science and practice, is the measurement sustainability of development using the system of indicators. The quantitative measurement of sustainability makes it possible to shape strategies for the development of countries and regions, taking into account the ecological, social factors that previously could not even compete with economic factors. For Russia, this is important from different perspectives. Among the main reasons there is a significant differentiation of regions in terms of development level and the predominance of "raw materials" in the structure of the economy of many regions. Rational use of natural resources is a necessary condition for the sustainable development of any state or region.

Authors: Tuleneva Tatyana
Published: June 2018

The paper deals with the phenomenon of raiding, which has become widespread and poses a threat to economic security of Russia in recent years. The wave of raiding is aimed at coal mining enterprises of Kuzbass, which have a stable holding structure and rising property prices due to development of strategic markets. In Russia almost all cases of hostile acquisition are accompanied by violation of civil, administrative, financial and criminal legislation. Raiding the market for corporate control caused by imbalance of current structure of ownership and control. The effect of raider acquisitions is damage to economy, social sphere and investment climate of Kuzbass and Russia. More aggressive and less civilized nature of raider acquisitions in Russia in comparison with other countries is conditioned by the specifics of socio-economic and institutional environment. In this regard, raiding in Russia doesn’t lead to effective distribution of rights to economic assets, but to aggravation of socio-economic and legal problems. Development trends of raiding currently characterized by a growing number of participants and complexity of forms of hostile acquisitions and ways of providing exposures.

At the same time, objective ecological and economical assessment should provide an adequate share of profit to every participant of development and processing of minerals: to the state and to the region – the administrative unit of RF, as the proprietor of the subsoil and minerals (obviously, this is the absolute rent and differential rent I), to the shareholder or the leaseholder, to the production worker (differential rent II), to the financier (the state, the bank or other legal entity), which have pretensions of the interest.
Ecological Education as a Factor of Mining Engineer Training
Authors: Sigareva Elena , Devyatkin Gennady , Baturin Sergey
Published: June 2018

To reduce environmental tension the development of Kuzbass ecological culture is of great importance. Its most significant component is environmental education, in general, and the training of mining engineers with high level of ecological education, in particular. The presence of environmental education in the field of nature management cannot yet become a guarantor of environmental problems solution. It should be embodied in the behavior of a person, in the image of his life, in the system of values, in his ecological worldview. Educational reforms have become a response to the challenges posed by the social-and-economic development to the personality of a specialist, including the personality of a mining engineer in Russia and its regions. To identify the features of environmental education in the transition to the sustainable development it is important to set the main links in the system of continuous education and their peculiarities, which radically change the quality of training of mining engineers and the demand for specialists in the labor market.
Challenges and Prospects of CLIL for Training Mining Engineers
Authors: Godzhaeva Natalia , Logunov Timur , Lokteva Marina , Tochilina Yulia
Published: June 2018

Increased international business contacts and mobility necessitates developing/mastering skills of communicating in a foreign language (FL) in engineering professionals, including mining engineers. However, the system of FL teaching for non-linguistic, and especially, engineering departments of the Russian higher educational institutions (HEIs) is generally inefficient. At the same time, given an insufficient level of FL skills in most content teachers, little support from their management, the lack of proper methodological training and complex linguistic learning situations, this process proves to pose considerable challenges for the existing educational setting of the Russian technical HEIs. This article summarizes the results of the expert opinion survey among Kemerovo State Technical University content and FL teachers showing a certain degree of doubt and unpreparedness in this respect. In this environment, the authors suggest that the optimal solution would be a gradual introduction of CLIL elements with a focus on more elaborated preparatory techniques. The study assumes the need for forming a specific support system provided by language teachers to boost learners’ linguistic confidence prior to students’ participation in CLIL format courses.

Authors: Kalenov Oleg , Shavina Evgeniya
Published: June 2018

Every year, the importance of innovation policy as a part of economy’s sustainable development is growing. The state approaches this policy thoroughly enough and carefully searches for ways of the most effective formation of the national innovation infrastructure. In this regard, the "Triple helix" model must be considered as one of the most successful models of innovation development of mining regions’ economy. The analysis of the possibilities of its implementation in the mining region (on example of Kemerovo region, Western Siberia, Russia) should be based upon the experience of another mineral resource region – Tomsk oblast. Among the problems hampering the effective functioning of the triplehelix model in the Kemerovo region, the authors describe the reduction in the staff engaged in research and development, intellectual and business migration, low financial activity, lack of support from federal and regional authorities. Only by implementing a system of measures aimed at applying the "Triple helix" model as the basis for regional innovation system, Kemerovo region can change its way for sustainable development.
Le problème de la représentation et sa solution dans la linguistique de Gustave Guillaume, lecteur de Saussure
Authors: Monneret Philippe
Published: June 2018

La centralité du concept de représentation chez Gustave Guillaume ne provient pas de la nature de l’objet de son étude, quel que soit le nom que l’on choisisse de lui donner : la langue, les langues ou le langage. Car une linguistique pourrait fort bien s’en passer, ou lui conférer un statut accessoire en préférant un autre concept directeur − la sémiose par exemple dans le cas de la linguistique saussurienne. Il n’est donc guère étonnant qu’on puisse finalement se demander à quel genre de problème répond la présence centrale du concept de représentation dans la linguistique de Gustave Guillaume. Si « promouvoir le langage à l’existence, c’est le promouvoir à la représentation − ce sans quoi rien n’existe pour l’esprit », ce n’est pas en raison de la nature du langage que le linguiste recourt au concept de représentation mais parce qu’il existe une certaine façon d’être un linguiste qui consiste à poser le langage comme un objet pour l’esprit, attitude qui se distingue, parmi bien d’autres solutions, de celle consistant par exemple à le voir comme un objet ou un « paramètre » de la vie sociale.
Des couples « interprétants » plutôt que des représentations : la démarche de Benveniste
Authors: Fenoglio Irène
Published: June 2018

Dans la perspective d’Émile Benveniste, il sera difficile de s’en tenir aux termes de « représentation » et « opération ». Plus pertinente est la notion d’interprétance, qui, empruntée à Pierce, prend dans la théorie benvenistienne du langage une valeur à la fois fondatrice (de la fonction du langage dans la société, de l’instance énonciative dans les activités de langage) et épistémologique. Elle sert de pivot entre la langue saussurienne et le discours, elle soutient la dimension méta de toute analyse linguistique. Cette notion d’interprétance se décline, chez Benveniste en divers dispositifs conceptuels couplés : désigner/signifier, sémiotique/sémantique, personne/non personne, selon les instances de langage visitées.
Optimal error estimates for fully discrete Galerkin approximations of semilinear parabolic equations
Authors: Meidner Dominik , Vexler Boris
Published: June 2018

We consider a semilinear parabolic equation with a large class of nonlinearities without any growth conditions. We discretize the problem with a discontinuous Galerkin scheme dG(0) in time (which is a variant of the implicit Euler scheme) and with conforming finite elements in space. The main contribution of this paper is the proof of the uniform boundedness of the discrete solution. This allows us to obtain optimal error estimates with respect to various norms.

Authors: Rudniak Joanna
Published: June 2018

The realization of the principles of sustainable development in the Silesia Voivodeship assumes, among others, a low-emission economy and the implementation of renewable energy sources e.g. by increasing the use of solar energy for yield of heat and electricity. The article presents perspectives for solar energy obtaining and the potential of this renewable energy source in the region. It was pointed out, that due to the specificity of the place, the influence of factors limiting the availability of solar radiation such as: air pollutants emitted to the atmosphere, local episodes, weather anomalies, cannot be neglected. Fulfilling the priorities of sustainable development can significantly contribute to improving the quality of atmospheric air, and thus improve the availability of solar radiation in the Silesia Voivodeship.
Comparison of resistance to damage of unalloyed carbon steels under the influence of hydrogen
Authors: Pietkun-Greber Izabela
Published: June 2018

One of the most commonly used construction material in industry is unalloyed steel S235 and S355. These types of steel are used for construction of ships, bridges, coastal construction, welded tanks, and in buildings. Due to the operating conditions, these types of steel may undergo hydrogen degradation in the process of manufacturing of welded structures or when operating the structures. This paper presents the results of study into resistance of selected types of non-alloy structural steels to hydrogen degradation. Tests were carried out to determine changes in mechanical properties in the static trials of stretching without hydrogen, and after saturation with hydrogen. Parallel fractographic and electrochemical studies were carried out. Hydrogen saturation was carried out at the time from 3. up to 24. hours in a solution of 0.1N H2SO4 with the addition of 2 mg/dm3 arsenic oxide (III) at an electric current density of 20 mA/cm2. The results of the tests have shown that the impact of hydrogen on the tested steels S235JR and S355J2 leads to a significant deterioration in their mechanical and electrochemical properties. At comparable concentrations of hydrogen, steel S235JR is less susceptible to hydrogen degradation and has greater corrosive resistance measured in 3% NaCl solution, in comparison with steel S355J2.

The article presents the parameters of the acoustic insulation capacity of a traditional wooden ceiling before and after renovation in a historical building from the beginning of the 20th century. Due to a change in the use of the building, the existing wooden ceilings were reinforced with two symmetrical C-bars with the use of Cofrastra 40 composite steel-concrete slab. The composite slab, being the ceiling support, made it easy to mount a suspended ceiling with thermal and acoustic insulation layers specifically selected for the building’s needs.

Environmental assessment over the course of the full life cycle of a building (LCA - Life Cycle Assessment) covers the environmental burden connected with energy consumption and the accompanying emission of contaminants into the atmosphere from the moment of obtaining a raw material and all stages of its processing and treatment, through the service life of a building, up to the moment that the use value of the building expires and the storage of waste. Literature on the subject is already very rich in this scope. There are numerous works pertaining to the guidelines for calculating all costs of the life cycle of buildings, i.e. environmental, economic and social costs. In these works, however, not much is said about the means of determining the life cycle of building structures. This is very important, especially in the case of the analysing the cycle of the further existence of buildings no longer in use, as well as newly designed ones. The article presents a method of predicting the performance characteristics of a building over the course of its use. The application of this method has been illustrated by the prediction of the performance characteristics of masonry walls, verified by studies carried out on existing buildings. The method - the purpose of research, can be applied to determine the life cycle (LC) of buildings for which LCCA (Life Cycle Cost Analysis) is carried out. A significant problem pertaining to every object in use is ensuring adequate reliability. The process of modeling reliability should have a mathematical basis enabling the problem to be described in detail. The ultimate aim is applying this description when solving problems connected with planning renovation work.

This paper discusses issues related to operation of environment protection facilities in immediate vicinity of natural water reservoirs, including fresh water reservoirs, located above and below ground. The subject of this study is a municipal solid waste landfill located in southwestern Poland and its related facilities included in the technological processes of waste disposal, treatment, and recycling. The paper briefly discusses the construction process stage and the first stage of operation of the studied facility in respect of their future impact on the environment. At the present time, waste is used to obtain landfill gas for electricity generation and materials to be reincorporated or disposed of, i.e. construction debris (brick, concrete), structural steel, firewood, and plastics. The range of topics presented in the paper is in accord with the sustainable development tendency and the paper specifically focuses on potential hazards arising from presence and operation of facilities of this type (built at a time when environment protection regulations were less restrictive as to their location). Continuity and effectiveness of insulation membranes of landfills are important inasmuch as once such landfills are filled with waste and then closed and reclaimed at the final stage, it will be extremely difficult to identify sites of potential leaks of basins, whose expected lifespan is several decades or a few hundred years. If such leaks are found within this period, it will be necessary to remove reclamation layers and strongly thickened waste in order to reach them [12]. Then, new damage resulting from operation of heavy equipment might occur. Therefore, apart from standard protection solutions of landfills, additional warning systems should be applied for maximum elimination of environmental pollution hazards, the range of which can be supralocal or even supraregional. Such systems should precisely indicate the location of probable places of hazards. It is not about damage to facilities, including cells, but about safety of their surroundings. Due to the vastness of the topic referred to herein, the paper has been narrowed down to include only one issue, i.e. tightness of cells intended for non-hazardous and non-inert waste.
Impact of blue space in architecture and possibilities of using

Trends in contemporary architecture are design environmentally, economically and socially sustainable buildings. When possible, where space permits, buildings are designed in harmony and contact with nature, water. Human's relationship to water and nature in the course of history changed. Water has a very special quality as an element in landscape design. Over many centuries and in many countries it has in turn been acknowledged and exploited, and it has inspired. It has been a great provider not only in physical terms, but also in the many ways it has contributed to both natural and man-made environments through its aesthetic qualities. The presented paper shows the possibilities of using blue spaces in the urban environment but also in the indoor environment. It has been shown that these elements have a high impact on the quality of the environment, but also contribute to reducing the air temperature and thermal islands in cities. The presence of natural elements in an artificial environment is an important aspect of life quality and well-being. Use of water elements bring the opportunity how put piece of nature into the urban environment, but also inside the buildings.
Strength and permeability of pervious composite prepared by using post-consumer plastic waste bottles
Authors: Solanki Pranshoo , Bhattarai Samikaran
Published: June 2018

This study focused on developing and evaluating a novel form of pervious polyethylene terephthalate (PET) plastic composite. This novel composite, called as PPC, produced from plastic waste, soil and aggregates, will offer an effective technique for reducing storm water runoff and help divert a large amount of plastic from landfills and incinerators. PPC samples with different PET to soil/aggregate ratios were prepared and then tested for indirect tensile strength and permeability. Permeability was conducted in a unique manner by designing and fabricating a new testing equipment. Both indirect tensile strength and permeability were within the expected values found in the literature for porous pavements. Results showed that indirect tensile strength values increased with PET content. It was also found that using PET alone is not strong enough in binding aggregates and therefore, a soil/PET ratio of one was found optimum for providing maximum strength. Permeability values decreased with the decrease of A/P (aggregate/PET) ratio which in general indicates that lower PET and higher aggregate content is suitable for higher permeability. A soil/PET ratio of one was found to provide higher permeability but strength could compromise. Findings from this study indicated that developed PPC could be used for low-strength construction such as driveways, sidewalks and parking lots.
