Authors: Kazanskaya L.F. , Smirnova O.M. 
Published: December 2019

Abstract
The processes of structure formation of hardening compositions based on hybrid binders as well as the controlled change of these processes allow obtaining concretes with increased strength and durability, for example, lightweight structural concretes on porous aggregates. Control of the structure formation of such concretes allows improving the quality and operational reliability of buildings and structures, saving binders, expanding the kinds of raw materials and solving environmental and economic issues. The results of the experiments have showed that the fineness of the hybrid binder effect the properties of the contact zone between the expanded clay aggregates and the cement matrix including the formation of calcium hydrosilicates on the surface of expanded clay gravel, which increases the adhesive strength. This leads to the increase of the quality of lightweight concrete based on expanded clay gravel.

Abstract
The problem of formation and development of the system of relations between partner companies in industrial clusters on the basis of determining the value chain as an indicator of its current performance and potential development opportunities in the future. The key prerequisites for the emergence of the problem were the emerging trends in the activation of the processes of integration interaction of companies within the created network structures. The peculiarities of their coordination mechanisms, power distribution and value extraction influence the market positioning of each company and the network as a whole. They also determine the direction of their strategic development. From these positions, there is a need to create an analytical database for each company belonging to the cluster or their “portfolio”, in order to make subsequent strategic decisions on the expansion of the cluster through new participants, the development of existing or even non-cooperation. The study identified the entire list of tasks related to the formation and management of the portfolio, however, the emphasis is on the diagnosis of the partner network, which offers the design of the portfolio of the cluster. The specificity of the industrial cluster in which there is always a leading company or a key link of partner companies that manage the value chain of each member of the cluster through the supply of raw materials or intermediate products, indirectly affecting the resource base of their development. The portfolio approach allows to distribute all participants of the cluster according to their contribution to the creation of added value of the cluster, to assess their own resources to support current activities and innovative development in the future, and to determine the feasibility of redistribution of added value at the expense of other members of the cluster and the leading company. The portfolio approach at the same time provides a basis for assessing the value of products manufactured by the cluster companies at the created or added value relative to the raw materials used by them. Comparing them with the prospects of market development improves the quality of decisions on structuring the portfolio of cluster members. The approach adopted in the study makes it possible to expand the understanding of the interaction of cluster members in the value chain, creating a methodological basis for the formation of a portfolio and access to the adoption of a whole complex of strategic decisions. Applied aspects of the research are considered on the materials of the industrial cluster “Technological valley” organized on the basis of JSC “RUSAL”. The theoretical and methodological basis of the study was the works of domestic and foreign scientists in different fields of knowledge from marketing, Economics, organizational theory to strategic management. The study used methods of comparative statistical analysis and expert assessments.

Authors: Kuznetsov A V , Vitchuk N A , Antsev Yu , Sabinina A L 
Published: December 2019

Abstract
It is practically impossible to efficiently manage the quality of the production process without determining the quantitative values for the indicators of its properties. Assessing the quality of the production process on a single, even decisive, indicator gives a one-sided, limited characteristic of the process, usually with a large number of properties. Therefore, for almost any process, especially for complex and multi-operational ones, it is necessary to carry out a comprehensive assessment on several parameters. In this regard, the indicator of the quality of the production process can be a complex, comprehensive indicator, depending on the single indicators of individual properties of the process. Such indicators include the indicator of continuity, the indicator of specialization, the indicator of plan fulfillment, the indicator of defect-free production, the indicator of progressivity, and the indicator of technical and economic efficiency.
The purpose of the study is to develop a methodology to use qualimetry methods for assessing the quality of industrial processes at industrial enterprises.
The objectives of the study: to determine the stages of qualimetric assessment of the quality of production processes; to develop the methods for calculating individual and integrated indicators of the quality of production processes; to practically implement the proposed stages of qualimetric assessment of the quality of production processes.
Research methods: qualimetric assessment methods, including expert method (preference method), integral assessment method.
Results. Indices that can act as single indicators of the quality of the production process are listed. The method to calculate the comprehensive indicator of the quality of the production process is shown on the example of the production process of manufacturing pipelines for gas turbine engines.
Findings. The proposed methodology for qualimetric assessment of the quality of production processes can be used when improving processes, and a comprehensive indicator of the quality of a process can act as a criterion for the efficiency of ongoing improvement activities.

Published: December 2019

Abstract
A review of existing technologies for cleaning carbon deposits from machine parts and mechanisms working in contact with hydrocarbon substances (fuel, lubricant, heating agency) at a wall temperature of 120 ° C to 350 ° C shows the diversity of such deposits in chemical composition and physical properties. Carbon deposits are divided into easily removable and difficult to remove deposits. Soot (smoke black) belongs to easily removed carbon deposits; varnish and coke are difficult to remove deposits. Soot is a product of incomplete combustion of fuel and includes carbon, light hydrocarbons (up to 30% by weight) and in small quantities various compounds, including carcinogenic. Lake and resinous deposits are carbon deposits that form as a thin layer, firmly held on the surfaces of the channels. Lake is a product of liquid-phase oxidation and consists of 20 … 40% of carbon molecules and 60 … 70% of hydrogen molecules. Coke (or coke deposits) are black solid carbonaceous substances consisting mainly of a mixture of carbon molecules and high-molecular-weight hydrocarbons (80%) and hydrogen molecules (20%). The most common methods of cleaning machine parts from various kinds of pollution and sediments are physical, chemical and chemical-thermal methods. Experimental work has been performed to evaluate the effectiveness of these methods. The experiments were carried out on an open loop installation with a flow reactor. Replaceable stainless steel and high-temperature alloy tubes were used as a reactor. The regime parameters during the experiment were maintained unchanged, and the temperature state of the reactor was monitored at specified intervals.

Abstract
Some biological indicators of chum salmon producers that spawn in the Inya river (Khabarovsk Territory, Sea of Okhotsk) in 2013-2014 have been studied. A comparative analysis of dimensional characteristics showed that in 2013, the range of changes in the length of chum salmon was higher (from 51 to 73 cm), while the dynamics of changes during the spawning season differed. Weight indices of chum salmon were higher in 2013. During the spawning season, both in 2013 and 2014 the average values of the mass of chum salmon decreased (in 2013 from 1.5 to 5.5 kg, in 2014 - from 2.0 to 5.0 kg). The chum salmon was harvested at the age from 2+ to 5+ years in 2013-2014. Fish prevailed at the age of 3+ years. The average value of the individual absolute fecundity was higher in 2013 (2412 ± 62 units) than in 2014 (2180 ± 83 units)

Authors: Shadrina E.V. , Maksimova S.N. , Poleshchuk D.V. 
Published: December 2019

Abstract
The results of scientific studies on the justification of the use of starfish of the Sea of Japan, Patiria pectinifera and Evastaerias echinosoma, in the technology of feed products are presented. The biotoxicity level of the studied objects was evaluated, its dependence on the season was determined. Two methods for the production of feed additives from starfish were defined, taking into account the bio-toxicity of starfish and the destination of finished products. The method of enzymatic hydrolysis (using the proteolytic enzymes) was recommended for non-toxic raw materials for obtaining the biologically valuable protein-mineral, protein and mineral feed additives. The method of combined hydrolysis (enzymatic in combination with thermal) allows the use of raw materials, characterized as “biotoxic”, with the aim of obtaining the safe protein and mineral feed additives. Technological parameters of the enzymatic (type and activity of the enzyme preparation, temperature, duration of hydrolysis and pH of the medium) and thermal (temperature, duration, pressure) hydrolysis methods are scientifically substantiated. Developed methods for the production of feed additives from starfish of the Sea of Japan provide feed additives that differ in chemical composition and purpose.

Published: December 2019

Abstract
Rational processing of multi-ton wood and plant waste with the production of promising products is an important task. One of the approaches to solve this problem is the pyrolysis of solid organic waste with obtaining the secondary liquid useful products in the form of raw bio-oils or charcoal suspensions.
In this regard, the work investigates the effect of pre-heat treatment of shredded wood on the mass yield of products processed by fast pyrolysis technology. As a result of the conducted research, it is revealed that the preliminary heat treatment has practically no effect on the mass yield of pyrolysis products. However, the output of the elemental composition of biomass changes: the content of carbon and hydrogen increases, the amount of oxygen decreases, the proportion of nitrogen remains unchanged, that improves the quality of the obtained pyrolysis products as raw materials for subsequent use in chemical technology.

Authors: Kozlovsky V , Aidarov D , Ermakov V , Kolesov S 
Published: December 2019

Abstract
the active zone of an electromechanical transducer (ET) contains several tens of geometrical parameters, each of which has a definite influence on the technical characteristics of the generator. When building a computer model, it is impossible to reflect the influence of each single input parameter on the output. Therefore, we propose to introduce a quantitative assessment of the influence of variations in all the geometric parameters of the active zone of an electromechanical transducer on the electromagnetic parameters of technical characteristics, and then select the most significant ones.

Published: December 2019

Abstract
An experimental work of empty fruit bunch gasification was conducted by using the bubbling fluidized bed to study the effect of the gasification temperature and steam biomass ratio (SBR) on the synthesis gas yield, Lower Heating Value (LHV) and Cold Gas Efficiency (CGE). Response Surface Methodology (RSM) was used to design the gasification experiment from the temperature range of 800 – 1000°C and SBR range of 0.5 – 1.5. Thirteen number of runs were generated based on Central Composite Design (CCD) with five replicated center points. Three regression models for predicting synthesis gas yield, LHV and CGE were developed and Analysis of Variance (ANOVA) was performed in this study. From ANOVA, the most influencing factor was gasification temperature which obtained higher F-value compared to SBR. The numerical optimization was also conducted in order to obtain the optimum condition to maximize the synthesis gas yield, LHV and CGE. From numerical optimization, gasification temperature of 800 °C and SBR of 1.14 were determined as the optimum condition which contributes to the maximum synthesis gas yield, LHV and CGE which are 1.25 Nm3/kg, 10.49 MJ/Nm3 and 90.72% respectively. The percentage error between the predicted and actual value of response variables was calculated and the error obtained lesser than 1%. Thus, it confirmed that the models obtained can be used to optimize the gasification of the empty fruit bunch.
