Abstract
Today surface water especially rain and thaw water became one of the environmental challenges for the cities. Those waters can be contaminated by different impurities including organics, oil products, heavy metals and etc. Utilization and reusing of those types surface water is the point of interest of many city agglomerations. In this paper preliminary results of Euglena gracilis CCAP 1224/5Z cultivation at highly organic contaminated surface water are presented. Cultivation was provided at illumination from 500 – 1200 lux depending on natural illumination in Moscow region. It was shown that during experiments that total organic carbon (TOC) content decreased from 41 mg/l to 15 mg/l in five days cultivation period. Final biomass concentration in case of cultivation on waste water exceeded concentration in the control flasks. Also the lipids content has been determined. In the biomass from flasks with surface water lipids content was from 24% to 32% to dry weight, depending on illumination and ambient temperature. Control biomass contains approximately from 28% to 30% in all experiments. Experiments with low TOC close to 10 mg/l showing close results – decreasing of TOC approximately at 50-60% in all flasks. Thereby it was demonstrated that it is possible in Moscow climate conditions during spring – autumn period to apply phototrophic microorganism E. gracilis strain for surface water treatment and in this case total lipids content a stay the same as in control cultivations.

AbstractThe publication justifies the feasibility of adsorption method of industrial wastewater treatment from aromatic compounds. Objects and methods of research are described. Studies of adsorption mechanisms of aromatic compounds on bentonites of various modifications made it possible to establish the most effective sorption rock clay-based materials, as well as filter compositions. Bentonite modified with carbon nanotubes after heat treatment 550 ° C proved to be the most effective with respect to the studied aromatic compounds. The principle of combining sorbents in a single filtering system, based on the sorbent selection for various groups of organic pollutants according to their ability to be ionized in an aqueous medium, has been proposed and investigated. Three most effective multicomponent adsorption filter compositions for sewage treatment from nitro and amino compounds were established. The proposed approach is aimed at designing local water treatment stations for industrial enterprises to deal with aromatic compounds via use of multicomponent adsorption filter compositions.

Published: November 2019

AbstractOne of the current modern scientific directions is the research and introduction of products obtained using nanotechnologies into various spheres of human activity. Among the variety of nanostructures, metal nanoparticles are found to be the most widely used, which, due to the uniqueness of their properties and small size, are considered as the most promising agents in the composition of bactericidal agents. They are used as specific carriers of drugs and as components in the composition of antibacterial agents. In addition, it has been proven that the bacteriolytic and bacteriostatic properties of some metals are greatly enhanced with decreasing size. Nanoparticles of various metals, among which silver nanoparticles are the most widely used, can be used independently; however, their high ability to aggregate requires the choice of stabilizers, which usually use natural and synthetic polymers. However, their use is limited due to the high toxicity of metallic nanoparticles. Therefore, the search for the safest options for metal nanoparticles is relevant. This article presents data on the toxicity study of prototypes of silver nanoparticles stabilized by synthetic and natural polymers on biological test objects.

Authors: Eliseeva S , Simakova I , Perkel R , Kostenko J , Smolentceva A 
Published: November 2019

Abstract
The article considers the technological capabilities and prospects for regeneration of frying fats in the catering enterprises using active filtration by a micro-granulated nanosorbent with subsequent recycling. The offered recycling technology involves the restoration of the quality of degraded frying fat with the purpose of its reuse and/or subsequent utilization. It is known that degraded frying fats contain products of oxidative and hydrolytic decomposition which vary according to their composition and structure. Actually, there is no universal technology that would provide the quality and safety indicators of frying fat for its further usage both in catering or for recycling in the market of secondary raw materials. Development of new microgranulated nanosorbent is based on fundamentally new technologies for modifying the surface of highly dispersed clay minerals of the Russian raw materials market using carbon nanomaterials. The granular sorbent is more preferable for use in catering, it allows easy separation of oil from the adsorbent without significant effort spent on filtration. The granular sorbent is lighter, more voluminous, and it significantly increases the adsorption efficiency even by contact method. The authors propose the technology of regeneration and recycling of frying fats with using new microgranulated nanosorbent in the catering enterprises.

Published: November 2019

Abstract
Samples of karst lakes, rivers, industrial effluents, and natural soil were studied for selection of bacteria for biodegradation. A metagenomic analysis of the used natural and man-modified media was carried out. It has been established that the most unique are the compositions of the metagenomes of natural karst reservoirs, as well as microcenoses of industrial effluents. Most of the detected bacteria belong to Proteobacteria. As a result of selection, strains of microorganisms with high activity of nitrocellulose biodegradation, aromatic nitrates, quinoline derivatives and amides were obtained. In particular, Pseudomonas strains and R. erythropolis, effectively utilizing nitrobenzenes, nitrocellulose, quinolines, which were isolated from industrial effluents. At the same time, Pseudomonas strains were isolated from the natural karst lake, which quickly utilized the nitrocellulose. It was also found that natural soils contain a large number of prokaryotes that can utilize organic nitrates. The results confirm the view that natural environments, due to high metabolic diversity, are the richest source of producers of a wide variety of enzymes. An obvious reason for the proliferation of the metabolic systems of technogenic pollutants in natural environments is the presence in natural environments of some quantities of their structural analogues - nitrogen-containing plant metabolites and soil microflora, as well as lignin decomposition products.

Abstract
The problem of rational use of saline soils as applied to the specific region becomes one of the main problems in Russia as well as abroad. The article describes the potential possibility to include these soils for rational land utilization in agro-industrial complex system. This will allow us to broaden the degree of their utilization on ploughed fields, hayfields and pastures in Siberia and Ural. Area of these lands as applied to this territory is more than 10 million ha. Obligatory chemical melioration is required for using of these soils on the level of climatic soil type. Its carrying out using gypsum, phosphogypsum and other ameliorants-coagulants allows us to increase fundamentally the fertility of solonetzic soils with their following implementation as yielding agricultural fields. It’s important to note that influence of ameliorants-coagulants takes place up to 40 and more years and their dose is up to 20 t/ha for perennial grasses and 40 t/ha for crops. The mentioned regions possess mineral, productive and scientific resources for the solution of such an important problem in conditions of Siberia and Ural.

Abstract
Waste materials resulting from the grain processing industries are harmless and easily amenable to enzymatic and microbial bioconversions. Basidiomycetous mushrooms grown in vitro are promising producers of protein and essential amino acids. Mushroom biomass production under appropriate cultivation conditions using agricultural by-products is a cheap and affordable way to obtain a high-quality food product. The present work explores the possibility of using grain wastes for the cultivation of golden oyster mushrooms under deep cultivation conditions. For these purposes, cornmeal was used as a source of carbon waste and gluten as a source of nitrogen. A high substrate colonization rate was observed. The fruiting cycle lasted about 26 to 28 days on the studied substrates. The most prolonged cycles were obtained on the medium supplemented with sawdust. The maximum and the minimum yields were obtained on wheat straw substrate (171.2 g per kg of substrate) and a grain waste substrate (113.4 g per kg) respectively. On birch sawdust subtrate and on a substrate of grain waste and birch sawdust mixture, the yields reached 143.2 g and 130.3 g in this order. The average yielding crop attained 113.4 g of fresh mushrooms grown on 1 kg of substrate under a relative humidity of 70-75%. This promising work stream not only proposes a waste disposal method, but also, a significant source of income for the grain processing enterprises.

Abstract
The present work is devoted to the problem of whey utilization, which is a by-product in the production of cheese and curd. We carried out analysis of modern Russian and foreign inventions aimed at waste-free milk treatment. We propose a modern waste-free method for curd production, which ensures the full use of the milk components. We carried out modeling of curd production process. The curd production process was presented as a combination of the most important technological operations – ultrafiltration whey treatment, mixing, thermocoagulation and clot treatment. We developed a structure of information flows, which totally characterizes waste-free technology of curd production. Alongside with that we proposed a structure of information flows accepted for mathematical modeling of the process. We propose models for formation of mathematical expectation of protein content in curd depending on the process factors, for which we used the regression equations. In this case, it turned out to be expedient to use linear dependencies. This can be explained by the fact that theory, research methods and calculation of linear models are developed deeper than others and require less computation. The question of applicability of such a model was resolved on the basis of checking its adequacy. The task of calculating the parameters of the model was solved on the basis of experimental data processing, which are the results of a passive experiment on study the waste-free curd production. Mathematical processing of experimental data allowed us to derive a regression equation and establish a correlation between the factors of curd production process and its protein content.

Published: November 2019

Abstract
It is necessary to know for calculation of solid household wastes thermal processing thermophysical characteristics. Existing methods consider the solid household waste layer as a multicomponent mix which thermophysical characteristics are defined taking into account volume fractions and properties of components, layer porosity thus not. A technique is proposed for determining the effective coefficient of thermal diffusivity of a multicomponent porous layer, constructed on the basis of the solution of the inverse heat conduction problem. The base of problem-solving procedure is the method of the discrete satisfaction of boundary conditions (DSBC). According to the proposed method, the dependence of the effective coefficient of thermal diffusivity of solid communal waste of the average morphological composition on the temperature and porosity of the layer was determined. The proposed technique can be used to determine the effective coefficient of thermal diffusivity of bodies with different porosity structures.
Immersive media in simulators of complex ergatic systems
Authors: Sergeev S , Burmistrov I 
Published: November 2019

Abstract
This paper shows a change in the paradigm of medium-oriented training of complex systems operators on simulators using high-precision models of real control systems and their application environments. Evolution of the technogenic environment leads to an increase in the complexity of professional activity, which hinders the implementation of simple algorithmic learning technologies. Forecasts to reduce the role of man in ergatic systems are not justified. New ergatic systems using artificial intelligence technologies require from operators qualities that exceed human capabilities, which requires an examination of projects and an assessment of user control complexity. The reasons for the non-classical “complex learning” methodology, which takes into account the student’s self-organization and orientation in a complex dynamic context, are shown. Promising methodological approaches to the development of simulators that implement symbiotic medium-oriented learning are considered.

Published: November 2019

Abstract
In this work, we studied the influence of the internal features of an open cell foam material structure on the efficiency of particle deposition and the pressure drop value of the medium. Constructing of the open cell foam filter models is based on the Distinct Element Method, which allows creating geometry with a random arrangement of pores in space. Calculations of the flow field and particle trajectories were performed using the ANSYS Fluent software package (v. 19.0). Experimental studies were conducted using samples created on the basis of the inverse matrix of 3D printed computational models. Also, models of various geometries with a fixed porosity of the medium are considered. Conducted numerical and experimental studies show that the filter model with the lowest porosity provides the highest deposition efficiency of particles. For a given fixed porosity of the medium, a filter with a change in the cells in diameter across the layers gives a lower value of the pressure drop, which is a significant advantage. The results can serve as the basis for creating aerosol filters with improved characteristics.
