Authors: Tatarinova Z G , Krylova A A 
Published: February 2022

Abstract
The provision of the population of Yakutia with vitamin products in the harsh natural conditions of the republic is especially acute. The remoteness of settlements, a complex transport scheme makes it difficult to deliver perishable fruit and vegetable products, the cost increases significantly, and the quality of plant products deteriorates during transportation. But Yakutia is rich in wild berries, among which special attention is paid to black currants. Black currant berries, leaves, buds contain a large amount of vitamins of groups A, PP, groups B, C and E, organic acids, pectin, sugars, tannins, essential oils and other biologically active substances [1,14]. The local population not only collects wild-growing black currants, but is also actively engaged in the cultivation of garden black currants in their backyards. Black currants are used both fresh and frozen; the berry is an excellent raw material for the production of preserves, jams, juices, etc. And like most berries, black currants are perishable products, therefore, the assessment of the compliance of black currants with quality and safety indicators according to the requirements of GOST 6829-2015 (UNECE STANDARD FFV-57:2010) “Fresh black currants. Technical conditions” is relevant [15].

Abstract
In agriculture, the use of humic preparations can increase the productivity, productivity of animals and poultry. The growth rate of consumption of humic preparations in 2021 … 2025 will be from 1 to 5% per year and the market capacity in Russia will be 1500 tons per reptile. Improvement of equipment for the production of humic preparations is urgent. The physical and mechanical properties of the humic suspension have been determined. In the production of humic preparations, medical centrifuges OS-6MC, a flow-through sedimentation centrifuge and a periodic vacuum evaporator (VVU) were used to increase the concentration of humic suspension. In terms of the energy of germination and germination of spring wheat, a rational method for increasing the concentration of humic suspension by evaporation has been substantiated. We have developed and patented a line with VVU to increase the concentration of humic suspension [21]. At the exhibition Golden Autumn - 2020 (Moscow) “For the production of highly efficient agricultural machinery and the introduction of advanced resource-saving technologies”: Kurgan State Agricultural Academy was awarded a bronze medal and a diploma: “For the development of a line for the production of a humic preparation.” When the time for the VVU to enter the operating mode is the sum of the heating time of the installation to the operating temperature and the time for the pressure drop in the installation from atmospheric to working. A method has been developed for calculating the time the vacuum evaporator reaches the operating mode at start-up. The heating time of the VVU with a tank of 50 liters from the initial installation temperature of 10 ° C to the boiler temperature of 85 ° C, and of the humic suspension to 60 ° C will be 30 minutes at a power source of 12 kW, which is confirmed by experiment. A method for calculating the parameters of the process of lowering the pressure in the VVU has been developed. Dependencies are obtained for studying the relationship between the design and technological parameters of the VVU when the pressure is reduced from atmospheric to working. The time of pressure reduction with a volume of 1 m3 of the vacuum system will be 5 … 6 minutes, which is confirmed by experiment.

Abstract
The study deals with the problem of creating high-quality comfortable residential urban environment with the inclusion of residential buildings that have different space-planning structure. The analysis of objects built both in the middle of the last century and in the last 20-30 years is carried out. The research provides comparative assessment of these buildings and complexes that have a developed network of service functions in their structure. As a result, these buildings and complexes have a more significant impact on the creation of high-quality comfortable living environment. Due to the different impact of a building on the living environment, the authors propose to introduce such a concept as «typological potential of a building». Depending upon the impact on comfort and quality of the environment there are residential buildings with «negative», «zero», «small», «medium», «above-average» and «high potential».

Abstract
Studies of the problem of natural recovery of biota are carried out within the boundaries of the influence of the closed mining enterprise “Kerbinsky mine of the Far Eastern Federal District from 2001 to 2011 Intensive development of gold and suprem deposits in the study area in the last century led to a huge accumulation of highly toxic mining waste. For their placement, the lands of the forest fund were seized. Large areas are disturbed here, where there is a weak natural renewal of vegetation. In this regard, the purpose of the study was to study the process of natural recovery of biota according to remote sensing data to ensure the environmental safety of gold mining. Based on the goal, the following tasks are defined: 1. Analyze and summarize the literary data on the named problem; 2. To study hyperspectral images, their decryption process, to analyze the relationship of the granulometric composition of soils with spectral reflectivity; 3. To calculate the areas of land disturbed by placer gold mining; 4. Develop proposals to reduce the negative impact of a mining facility on biota. Spectral analysis established high concentrations of compounds of copper, lead, zinc, mercury not only in waste, but also in environmental components. Experimental studies were conducted using methods of remote sensing of the Earth. The NDVI index was calculated, according to the formula NDVI = NIR - R / NIR + R, where NIR - the reflection coefficient in the near infrared region of the spectrum; RED - reflection coefficient in the red region of the spectrum. With the help of this index, the contours of the disturbed lands were also highlighted. The analyzed data indicate that in recent years (2011-2021) the area of disturbed land is increasing. The results of the NDVI calculation showed that in the summer months along the river valleys of the Kerbisky mining region, it is 0.15-0.25, which indicates the absence of vegetation or a low degree of development of the green mass. The root vegetation is completely destroyed. These guidelines, written in the style of a submission to J. Phys.: Conf. Ser., show the best layout for your paper using Microsoft Word.

Published: February 2022

Abstract
This paper studies the conditions for the use of plastic pipes in rainwater drainage systems. In this research, the author undertakes a literature review and finds out that the share of plastic pipes in the construction of gravity sewage network has significantly increased over the past 20 years. Plastic pipes low roughness ensures higher flow rates of wastewater. The peculiarity of rainwater drainage calculating methodology leads to the fact that an increase in the speed of wastewater movement leads to the formation of larger wastewater discharge in the design section of the pipeline with the same rainfall intensity. It is established that at present the cost of rainwater drainage systems construction from polypropylene pipes is 80-100% higher than from reinforced concrete (excluding the construction of pumping stations and wastewater treatment facilities).
Social Housing in Russia: Yesterday, Today, Tomorrow
Authors: Solodilova L A 
Published: February 2022

Abstract
The main type of housing construction in modern Russia is an apartment building (MKD) with combined types of property: commercial and municipal (state). The current situation is a direct reflection of the inexpressive architectural appearance of mass residential development. Municipal apartments of the state form of ownership, which are part of the MKD, can and should be allocated to a separate class of social housing with subsequent architectural and spatial development and taking into account new effective forms of private rental entrepreneurship and management. The reason for this are the intensive efforts of state structures, which are increasingly entering the rental housing market, creating competition for the shadow sector of rented apartments by the so-called private “rentiers.” In this regard, two main directions for the development of social houses of private-state entrepreneurship were identified: rental apartment buildings of a commercial type and municipal houses of a non-commercial type. The development of social houses of private-state entrepreneurship will take into account the socio-economic needs of society and will make the architecture of residential development more diverse.

Published: February 2022

Abstract
According to the results of geological fieldworks in the north-east of Sakhalin Island on the Schmidt Peninsula and in the Pogranichny Depression, Cenozoic outcrops were studied in order to explore the siliceous deposits of the Pilskaya formation. Samples were taken for analytical studies, small structural forms that are indicators of tectonic stress, were studied. It is shown that the fracture intensity depends on the lithology, the position of the observation point relative to disjunctive and/or plicative structures. A sharp nonuniformity of the stress field in the vicinity of the Pogranichny Depression is noted, reflected in the nature of the bedding planes, structural discontinuities and parageneses.

Combined Subset Simulation and Comprehensive Learning Particle Swarm Optimization in Reliability-Based Structural Optimization
Authors: Sutha Arnut , Huynh Van Thu , Tangaramvong Sawekchai 
Published: February 2022

Abstract
Reliability-based design optimization (RBDO) addresses the cost-effective integrity design of structures in the presence of inherent uncertain parameters. Processing this class of problem is challenging from the computational burden to determine the failure probability of structures violating the limit-state function. This paper proposes an efficient decoupling RBDO method that advantageously couples a comprehensive learning particle swarm optimization (CLPSO) algorithm with a subset simulation (SS), termed as SS-CLPSO approach. In essence, the proposed method iteratively performs the CLPSO assuming deterministic parameters based on the most probable point underpinning limit-state functions updated within the reliability evaluation process. Based on the CLPSO design data, the SS approximates the spectrum of limit-state functions under uncertain parameters, and hence enables the significant reduction of Monte-Carlo simulations for the failure probability prediction. The SS map outs the failure probability from the conditional samples constructed at each intermediate event. The proposed SS-CLPSO terminates the optimal solution to the RBDO problem as when the resulting failure probability converges to the permissible threshold. The applications of the present approach are illustrated through the steel truss design under probabilistic uncertain parameters and constraints.
Effect of norcholine fluid derivative on the resilience of mild steel to electrochemical degradation in weak HCl media
Authors: Loto R T 
Published: February 2022

Abstract
The resilience of mild steel to electrochemical degeneration in weak electrolyte corrosion (0.5 M HCl) was assessed at discrete concentrations of Norcholine derivatives by potentiodynamic polarization and open circuit potential analysis. Degradation rate of the steel substantially declined with augmentation of Norcholine concentration from 9.49 mm/y in control HCl (no Norcholine) to 0.27 mm/y at highest Norcholine value of 15%. The degradation rate at this inhibitor concentration correlates of 97.1% protection performance. Norcholine demonstrated cathodic inhibition effect from observation of the negative deviation in corrosion potential. Norcholine was also observed to indicate substantial passive reaction mechanism on the anodic polarization regions of the polarization graphs. This translates to evolution of non-porous layer on the steel exterior. Open circuit potential graphs indicate substantial variation between the inhibited and acid degraded graphs of the steel. Mathematical computations through analysis of variance demonstrates Norcholine concentration and potential tracking time are statistically important variation sources influencing the protection performance of Norcholine at values of 68.03% and 26.4%.
Modified Scheil equation for the Cu-Sn system and comparison of hardness and electrical conductivity of Cu-8.5wt% Sn alloy directionally solidified
Authors: Cruz R A , Santos G A , Nascimento M S , Teram R , de Luca R , dos Santos V T , da Silva M R , Couto A A 
Published: February 2022

Abstract
The Scheil equation, which estimates the concentration of solute in the solid at the solid/liquid interface, does not account for the curvatures of liquidus and solidus lines. We modified the equation to account for these curvatures and compared some microsegregation indexes obtained by the original and the new equations with data from the literature about the Cu-Sn system. The new one can furnish a better approximation of the range of concentration of solute, but a poorer estimate of the maximum volume fraction of the eutectoid mixture. At last, we compared the hardness and electrical conductivity of an upward solidified alloy of this system with its equivalent commercial one. The as-cast alloy has a lower hardness and a higher conductivity due to its columnar structure.
