Assessment of the Production Potential of the Arctic Mining Sector
Authors: Tsukerman V A , Goryachevskaya E S 
Published: February 2022

Abstract
It is defined that the development of the world economic system in modern conditions is largely determined by the consumption of natural and, first of all, mineral resources. The process of exploiting Arctic mineral resources is complicated by specific features associated with taking into account climatic features, increased costs and conditions of economic activity. It is shown that in recent years experts showed increased interest in assessing industrial potential which is determined by the need to increase the pace of territorial innovation and industrial development. In this regard the aim of the work is to assess the production potential of the mining sector of the Arctic economy which determines the possibilities of using the entire set of resources for effective growth. The performed analysis of the production potential of the Arctic mining sector showed significant differences in the functioning of industrial enterprises in the Arctic regions. It is determined that the Arctic regions are characterized by raw materials specialization. The extraction and processing of minerals in the Arctic regions accounts for more than 50% of the added value and about 60% of tax revenues to the budgetary system of the Russian Federation.
It is concluded that the most significant production potential of the Arctic mining sector is typical for the Nenets Autonomous Okrug and the minimum - for the Murmansk Region and the Chukotka Autonomous Okrug. It is shown that in terms of production potential the Arctic regions are ahead of the average Russian values but at the same time they are characterized by a low level of innovation activity.
To increase the production potential of the Arctic mining sector it is necessary to conduct scientific research in the direction of ensuring the competitiveness of industry sectors and greening production primarily through the development and implementation of modern innovation technologies.
Generation of Hydrogen at a Gas Distribution Station

Published: February 2022

Abstract
In 2019 the UN announced a course to achieve carbon neutrality of industries by 2050. In this connection interest in hydron fuel has increased. Hydrogen due to its ecological characteristics is considered to be one of the most promising energy sources. It does not pollute the atmosphere, as the product of its combustion is water; it has a high energy intensity and is also the most abundant element on the planet. Despite the fact that most of the hydrogen is produced by the steam reforming of methane, the most environmentally friendly way to produce hydrogen is the electrolysis of water. However, the problem with this method is the high cost of electricity, which in addition in most cases is a product obtained from the combustion of primary energy sources. A modern gas transmission system can become a secondary source of electricity for hydrogen production, thereby solving the problem of utilizing excess pressure energy at gas distribution stations (GDS). The technological solution for using this energy is the installation of turboexpanders and the electrolysis of water at the GDS in order to generate hydrogen.

Abstract
In practice, the industry and the business sector have felt the impact of the coronavirus that has spread around the world. Today it is not known when the system will recover, but it is already quite clear that the post-covid reality will require radically new approaches to the organization of mining operations. Usually, the conservative mining industry in Russia has felt the influence of new trends set by the pandemic, such as, for example, the transition of employees to remote work, which has spurred an accelerated transition to automated work; a change in the distribution chain, are inseparable from the closure of borders, the acquisition of new skills from staff, and others. This article focuses on the development of mining assets in the mining industry. The article concretizes the essence of geometry. Appropriate solutions for end-to-end optimization of the “mine-factory” system are outlined due to a deep understanding of the characteristics of the ore and the introduction of digital tools. The most popular innovations necessary for implementation into the modern mining process have been identified, ranked according to the categories “Production materials, technologies and equipment”, “Automation and digitalization”, “Field development”, “Technologies of deep processing of raw materials: green chemistry”, “Technologies of deep processing “processing of raw materials: green metallurgy”. The production assets of the Polar Division are analyzed using the example of PJSC Mining and Metallurgical Company Norilsk Nickel. As a project initiative to improve the efficiency of ore mining within the mine field, the reconstruction of a skip ventilation shaft from a cage to a skip-cage is being created. A variant of solving the geomechanical problems of the company is being considered.

Published: February 2022

Abstract
The importance of polymeric materials in modern life can hardly be overestimated. The annual growth of their production and consumption is one of the main directions of the development of the world economy. At the same time, the problem of recycling polymer waste after the end of the use of products made on their basis arises (according to various sources, only 10-15% of all produced polymers are used for the manufacture of containers). Fully biodegradable plastics are practically non-existent today. Any of the proposed solutions has its own advantages and disadvantages, which require commensuration with consumer characteristics, price, production costs. Independent examinations show that a truly complete degradation of polymers is possible only if they are made from plant materials. The article discusses the rationale for the feasibility of building a plant for the production of biodegradable materials based on plant materials in the Tyumen region.

Published: February 2022

Abstract
Crisis events in the economy of the first half of the 21st century are considered as a manifestation of their inevitable cyclicality based on the correlation analysis of statistics of anomalous natural and climatic phenomena. Using spectral analysis methods, the rhythm of these events in the past was investigated, and simultaneously with the use of a specially developed neural model, their cyclical manifestation is predicted for the coming period - until 2049. It is shown that the cyclical nature of natural and climatic phenomena can be considered as one of the economy’s macroeconomic indicators when conducting long-term forecasting of its dynamics.
The Problem of Choice Between Measurement Techniques
Authors: Demyanenko S N , Chechet V A , Redreev G V 
Published: February 2022

Abstract
The assessment of the current conditions of any technical object is based on measurement. Thus, choosing the qualitative descriptor of the object that is to be assessed represents a relatively complex task. This is related both to the informative value of the qualitative descriptor and to the need for applying one or another measurement technique. There are three different ways to deal with the designated task. One possibility is to fix the required level of informative value and choose the measurement technique based on criteria such as the least money expenses for measuring, the shortest measurement duration and the specialization level of the measurement instruments. The second option is to choose specific measurement techniques and obtain the most complete information possible. The third possibility consists in a compromise between the information content of the descriptor and the overall expenses for measurement techniques. By convention, the first option is applied while facing this task, in which the information on the technical conditions of the object is obtained choosing adequate measurement techniques. Determining the value of the structural parameter of the technical conditions is not always possible. The diagnostic parameter, in its turn, is determined by the structural parameters only at a certain level of probability. The producers of machinery are constantly improving their products, upgrading the design of mating parts, changing the properties of wearing surfaces and introducing new materials. As a result, the aforementioned interrelations between the structural and diagnostic parameters are significantly redetermined, whereas the previously engineered diagnostic devices and the implemented methods lead to the ambiguity of the diagnostics. The areas of such ambiguity are here taken into account using a compression vacuum method in order to determine the technical conditions of the sleeve assembly of an internal combustion engine.

Published: February 2022

Abstract
This article considers the prospects of building highly automated ferry lines on the internal waterways of Russia. To do this, the authors used the engineering-cybernetical approach to determine the basic provisions of the concept for the construction of unmanned ferry lines. The key provisions of the concept account for the integration of unmanned ferry lines in the river information and communications triad based on the hierarchical principle: the corporate river information and communications service - the river information service - the automated ship-traffic control system. The authors consider the prospects of using unmanned ferry lines on rivers where the navigation and information support for the unmanned ferry can be provided using radio technical facilities covering both the points of departure and destination. The authors also reviewed the arrangement of unmanned ferry lines for situations where the departure point and the destination are far from each other. This type of unmanned ferry line is suitable for reservoirs or large lakes.
Finally, the research work also provides a rationalization of the selection of the automation level for unmanned ferry lines following the terminology used by the work team for inland water transport of the Committee for the Inland Water Transport of the UN Economic Commission for Europe (UNECE).

Published: February 2022

Abstract
The complexity of treating wastewater of small sewerage facilities lies in the small volumes of treated water, considerable irregularity of their inflow to treatment facilities, inhomogeneity of their composition by hours of inflow to treatment facilities, as well as high requirements for treated wastewater discharged usually into low-power water bodies or to the surface. The treatment facilities should exercise the functions of purifying wastewater from pollutants according to regulatory requirements. A sewerage system and wastewater treatment technology have been considered by the example of the town of Fort-Shevchenko. A technology for purifying similar wastewaters using clarifiers with a sludge blanket formed by activated sludge flakes has been proposed. This technology has been introduced at several treatment facilities in the East Kazakhstan region that are successfully operating in compliance with the technical and engineering operation requirements. The treated wastewater quality indicators are given.

Finite Element Study on Forming Metal Sheets with an English Wheel
Authors: Fann K J 
Published: February 2022

Abstract
Because of the application trends of Industry 4.0, small-volume large-variety production becomes the daily life in the manufacturing industry. Techniques to flexibly shape sheet metal parts are therefore more and more inquired. This paper is thus aimed to have a preliminary glimpse at the shaping process made by the English wheel, which is broadly used by craftsmen, via Finite Element Analysis. As a result, the parts shaped by an English wheel with a zigzag path show a curved surface having a homogeneous curvature. The more the impression from the bottom roll onto the sheet metal, the smaller the radius of the bottom roll, and the thinner as well as the more compliant the sheet metal, the larger the curvature of the shaped metal part.

Published: February 2022

Abstract
Hybrid nanostructures based on two-dimensional (2-D) materials such as transition metal dichalcogenides (2-D TMD’s), transition metal oxides (2-D TMO’s), and graphene are gaining significant attention for their potential application as semiconductor sensing devices owing to their excellent structural, electronic, and optical characteristics. The present work reported 2-D ternary nanocomposites (MoS2/WO3/RGO) as organic vapor sensing material, synthesized using microwave assisted method. Formation of ternary composite system proves to be an efficient strategy to develop novel high performance vapour sensors, providing multiple degrees of freedom and opportunity to exploit the synergistic properties of the resulting material to its full potential for a particular application. The synthesized MoS2/WO3/RGO nanocomposites has been characterized for morphological, and structural analysis through SEM, XRD and FTIR spectroscopic techniques. The electrical and sensing studies of synthesized material is evaluated through IV characteristics using Keithley electrometer. The sensing characteristics has revealed that the synthesized sensor has high sensitivity, good stability at room temperature and outperforms the result obtained from single or binary counterparts. The formation of the heterojunction and electronic modulations at the interface of MoS2, WO3 and RGO results in improved surface charge transfer mechanism and enhancement of sensing performance.

Abstract
In this study Taguchi Optimization Technique was used, followed by ANOVA to evaluate the machinability i.e. turning of a hybrid Mg/(8wt%SiCp+2wt%Al2O3p+1wt%Grp) MMC using PVD coated cermet tool under the dry turning conditions. Several experiments were conducted using the L27 (313) orthogonal array on NH26 automated lather machine. ANOVA was used to determine the impression of the turning parameter on the VBmax of the tool flank. The finding of the research work investigated that the cutting speed in the dominant factor influence the tool wear width. The confirmation test revealed that the Taguchi technique has been successful in the optimization of the machining parameters for minimum tool wear. The optimal parameter arrangement for minimum tool wear width is at cutting speed of 120 m/min, with the feed rate of 0.4 mm/rev and depth of cut at 0.75 mm. The scanning electron microscope images revealed notches, groves and pits on the tool flank face that is clearly visible at different magnification units. Herein, this paper discuss about several reported synthesis techniques, various characterization techniques used for structural and surface properties identifications, different morphologies and various potential applications of transition metal oxide based nanocomposites.

Published: February 2022

Abstract
The composites are renowned for better properties than base alloy. In general, 2-8% weight fraction of reinforcement has been researched for various industrial applications. The addition of reinforcement gives improvement in mechanical properties but badly affects ductility. Liquid route method (casting) has been employed for fabrication of SiC reinforced aluminum composites. Machining has been performed by controlling input parameters such as cutting speed, feed rate and depth of cut. Roughness parameter (Ra) and material removal rate (MRR) have been considered for evaluation of surface quality and productivity respectively. Only MRR has been given consideration for rough machining conditions. Whereas, both surface roughness and MRR have been considered for the finish machining conditions. Standard L9 orthogonal array have been employed for the experimentation. The occurrence of hard reinforcement in the base alloy creates the casted composite tough to machine. The confirmation experiments have been performed with the optimal settings of process parameters to confirm the output responses.
Experimental investigation and optimization of weld bead shape factor and form factor using recycled steel slag as a flux in submerged arc welding process
Authors: Saini Sumit , Singh Kulwant , Garg Jatinder 
Published: February 2022

Abstract
The quality and productivity of welds produced depend upon the weld bead profile which is represented by weld penetration shape factor (WPSF) and weld reinforcement form factor (WRFF). The weld profile is further dependent upon welding parameters used hence optimization of welding parameters is essential. In this research work, the steel slag has been recycled to act as a flux in submerged arc welding. The effect of process parameters on WPSF and WRFF using recycled slag has been evaluated. The mathematical models have been developed from the data created. It was found that the weld deposited with recycled steel slag performs well as the WPSF and WRFF are comparable with that deposited with fresh flux. The welding parameters have been optimized using the desirability approach and genetic algorithm. The genetic algorithm yielded more accurate results as compared to the desirability approach.
Static and Dynamic Mechanical Characterization of Polydimethylsiloxane (PDMS) under Uniaxial Tensile Loading
Authors: Kumar David , Singh Sarthak S. 
Published: February 2022

Abstract
The present study is based on performing mechanical characterization of polydimethylsiloxane (PDMS) under tensile loading. PDMS samples are developed by mixing prepolymer and curing agent with 10:1 ratio. Mechanical characterization of the PDMS samples is carried out using static and dynamic mechanical testing methods. In particular, the material is characterized under monotonic loading, different strain rates, and force-controlled cyclic loading. The monotonic loading tests are performed at different grip tightening levels to optimize gripping that avoids slipping and reaches failure point. The strain rate dependency and cyclic loading tests are performed to study the viscoelastic behaviour of the material. Strain rate dependency tests are carried out at the strain rates of 6.7×10-3 s-1, 3.2×10-2 s-1, and 6.2×10-2 s-1. The hysteresis tests are performed at the force rates of 0.1 – 2 N/s. The obtained results show that fixing the testing specimen made of soft hyperviscoelastic material such as PDMS is challenging and can significantly affect its stress-strain behaviour and mechanical properties. A higher strain rate increases the stiffness of the material due to the viscoelastic nature of the material. Observing the stress-strain curves, with respect to the lowest strain rate case, the curve for 6.2×10-2 s-1 strain rate diverges at 40% strain compared to 3.2×10-2 s-1 strain rate curve that diverges at 80% strain. The material shows a nonlinear hysteresis behaviour and similar energy dissipation for the considered force-controlled cyclic loading cases.
