Abstract
The paper presents the results of studies on the effect of soybean seed inoculation with bacterial preparations on yield, yield structure indicators and the economic efficiency of this method in soybean cultivation. The studies were carried out under the conditions of the zone of unstable moisture in the experimental field of the Armavir experimental station of All-Russian Research Institute of Oilseeds named after V.S. Pustovoit, the soils of the experimental plot are ordinary chernozem. The studies were carried out in 2013-2015 on an early Duniz ripe variety. On average, over three years of research, it has been established that improving the level of nutrition due to biological nitrogen fixation during the inoculation of seeds with bacterial preparations, both foreign and domestic, makes it possible to obtain an increase in soybean grain yield from 0.10 to 0.38 t/ha. The maximum yield from the use of bacterial preparations was obtained when seeds were treated with rhizotorphin, strain 626a with a film-forming agent - 1.98 t/ha, the yield increase compared to the control was 23.75%. Inoculation of seeds with bacterial preparations has a positive effect on the parameters of the elements of the crop structure, the largest: the number of grains - 51.1 pieces per plant and the weight of grains from one plant - 7.5 g. The economic efficiency of this technique is expressed in the profit received - 25,182 thousand rubles per ha with a profitability level of 103.6%.

Abstract
Modern man cannot imagine his diet without milk and dairy products, above all cheese. Uzbekistan has traditionally provided dairy products, including cheese, not only for itself but also for other neighbouring countries. Cheese has a long history and this naturally fermented dairy product contains a range of distinctive flavors. Microorganisms in variety cheeses are an essential component and play important roles during both cheese production and ripening. However, cheeses from different countries are still handmade, the processing technology is diverse, the microbial community structure is complex and the cheese flavor fluctuates greatly. Therefore, studying the general processing technology and relationship between microbial structure and flavor formation in cheese is the key to solving the unstable quality and standardized production of cheese flavor on basis of maintaining the flavor of cheese. Cheese processing, including cheese-making, cheese preparation and the different stages of cheese-making. Much attention is given to bacterial starters, bacteriophages, milk-forming enzymes used in cheese-making, and the production of new cheese varieties, including those in Uzbekistan. This paper reviews the research progress on the general processing moulding, pressing and salting points of natural cheese, the biochemical pathways for production of flavor compounds in cheeses, the diversity and the role of yeasts in cheese.

Abstract
The article discusses the impact of various winter wheat cultivation technologies on the agrophysical factors of chestnut soil fertility. Agricultural techniques aimed at creating optimal conditions for the growth and development of winter wheat, changing microclimatic conditions in the agrocenosis, are diverse and different in purpose. Properly chosen crop cultivation technology is of great importance in increasing the effective soil fertility. We have carried out field experiments and studies in the arid zone of the Stavropol Territory on chestnut soils. Agrophysical factors are a set of soil properties that characterize the reserve of productive moisture, structural and aggregate composition, soils, water resistance of soil aggregates, as well as agrotechnical parameters of soils. The studies were carried out in all phases of growth and development of winter wheat. The results show that the maximum reserve of productive moisture was observed in the spring tillering phase using the No-till technology and such a predecessor as corn for silage. The number of agronomically valuable aggregates also prevailed according to the No-till technology in the spring tillering phase. The maximum values of water resistance and structural coefficient were also obtained using this technology. Based on the results obtained, it can be concluded that in the arid zone of the Stavropol Territory it is advisable to cultivate winter wheat using the No-Till technology.

Published: August 2022

AbstractStudying the wear process of shares operating in an abrasive environment on the soils of meadow, light and typical gray soils, the parameters of the limiting state are analyzed and it is revealed that the main parameters that contribute to the rejection of shares are the parameters of the occipital chamfer. It is also noted that maintaining a generalized index of blade rejection creates an opportunity to generally assess the degree of wear of the blade, for all changing parameters at the same time and quantify it. This facilitates the assessment of the quality state of the wear of the blade, not only of an individual, but also of groups of compared working bodies. According to this indicator, by conducting a comparative assessment of various designs and working conditions (or tests), it is possible to determine the weakest of them in terms of bluntness or the most abrasive working environment of the working bodies.

In situ–produced polyurethane-based thermoplastic elastomers: the effect of the acrylonitrile content of the rubber phase
Authors: Kohári A , Bárány T 
Published: August 2022

Abstract
We prepared thermoplastic dynamic vulcanizates (TDVs) with an in situ–produced thermoplastic polyurethane (TPU) matrix. We used unfilled acrylonitrile butadiene rubber (NBR) with different acrylonitrile contents and investigated the effect of the polarity of the rubber phase on the properties of the TDV samples. The results show that the acrylonitrile (AN) content of the rubbers affects the tensile strength and modulus slightly but the strain at break of the TDVs only negligibly. The results of TDVs are in between those of TPU and unfilled NBRs, demonstrating the feasibility of the TPU/NBR combination.

Abstract
The application of industry 4.0 guidelines is also an integral part of the life of ISD Dunaferr Zrt. Working closely with technology professionals, we have created a data analysis system that processes data from continuous steel casting. The life cycle of slabs can be traced in a complex way from raw steel production to the end of hot rolling. In an industrial environment, the program provides an opportunity to study the effects on slabs (e.g. change in casting speed, change in mould level, change in the position of tundish stopper rod (TSR), etc.). The results provided by the system are suitable for both qualifications made by experts and automatic one during the visual inspection using the web display system. In this paper, we examined the correlation between the slabs burdened with known significant changes in casting parameters in the cast sequence and the slabs with significant changes classified by the data processing system to verify the reliability of the data analysis system. The results confirmed the reliability of the data analysis system and pointed to the greater reliability of the study of cast length-based changes versus time-based changes.

Abstract
In this study, gas atomized iron powder with the particle size of 10 - 100 μm was coated in two different ways. The coating was created by a chemical procedure, the powder was treated for different periods of time with the classical and modified Stöber process. Toroidal samples were then prepared using different pressures. These samples were heat treated in an argon shielding gas. The complex permeability spectra of the green and heat-treated samples were measured and the effect of pressure, chemical coating time and heat treatment was investigated. The formation of the coatings in each case was confirmed by scanning electron microscopic examinations. Samples with long-term chemical treatment and without heat treatment were appropriate in high-frequency applications (μstat
= 50, fFMR
= 5 − 15 MHz). After the heat treatment, the relative initial permeability has increased significantly (160-180) and the resonance frequency has decreased (400-4000Hz). Furthermore, it can be stated that a more coherent, thicker coating can be obtained with the modified Stöber method.
Optimization of bonding technology for aluminium foams using femtosecond laser beam pulses
Authors: Tajti F , Petrovics B 
Published: August 2022

Abstract
Weight reduction is becoming increasingly important in the automotive industry. To achieve this goal, special materials are needed. We are no longer just using solid materials in production, but also metal foams. Metal foams, in particular aluminium foam, have high strength but their mass is a fraction of that of solid metals. Aluminium foams are usually not used on their own, but as a reinforcement for some structural element. The joining of these materials needs to be improved, as low weight is also important here. Therefore, bonding is a technology often used. For metal foams, use a little adhesive to avoid filling the pores. So we are only bonding on a very small surface area, so it is very important to increase adhesion. We used laser beam surface treatment to increase adhesion. The interfacial properties of the laser beam surface treated aluminium foam were first investigated by distilled water wetting and then, after setting the optimum parameters, the wetting of the adhesive was also investigated.
The effect of Argon Shield Gas and Cold Air for Friction Stir Welding of Ceramic-reinforced Aluminium Matrix Composite and Aluminium Alloy
Authors: Kovács Zs. F. 
Published: August 2022

Abstract
A dissimilar joint between friction stir welded ceramic-reinforced C35 aluminium matrix composite and AA7075-T6 aluminium alloy has some difficulties. For fusion welding of aluminium, a shielding gas always has to be used to achieve the required welding joint quality, but in the case of Friction Stir Welding (FSW) no shielding gas or filler material is required for welding aluminium alloys. To achieve a good welding joint between super strength aluminium alloys and ceramic-reinforced aluminium matrix composites some sort of support is needed. In this study, the effect of blowing argon gas and cold air (0 °C) was investigated with regards to the quality of the welding. For the experiment a cylindrical pin tool, a different feed and a constant rotation speed were utilized along with a marble table to avoid harmful heat conduction. For evaluations, hardness and tensile tests examinations were carried out to classify the mechanical properties of the joint. Experimental results showed that the blowing of gas and cold air having a positive effect on the welded joint quality and also for the weld face. Additionally, the optimal welding traveling speed and the temperature of the air blown was determined.

Published: August 2022

Abstract
The present work investigates the microstructures, mechanical properties and deformation behaviors of the 316L stainless steel fabricated by selective laser melting (SLM). The initial dislocation density of as-SLM and conventional samples is measured using x-ray diffraction (XRD). It is found that the high dislocation density is obtained by SLM, contributing to the enhancement of yield strength. Twinning has occurred at the early stage of SLM deformation, which undergoes obvious grain rotation and twinning development during the tensile tests. However, only a few transformed martensite is presented in the deformed samples, and no significant grain orientation changes are observed.

Abstract
Plastic microparticles are pollutants that have been proven to cause serious harm to human health and the environment. Using the core data set of Web of Science (WoSCC), this study analyzes the spatial and temporal distribution of 7,076 relevant articles on microplastics (MPs) and nanoplastics published from 2004 to 2021. The visualization software CiteSpace 5.8.R3 was used to analyze the research status and emerging trends in this field. The results show that MPs and nanoplastics are important research hotspots for environmental pollution and biological toxicity, with research carried out mainly in the fields of environmental science, material science, and toxicology. Research on the impact of MPs and nanoplastics on human health is still in its infancy.
Investigating the limits of superconductivity in UTe2
Authors: Weiland A , Thomas S M , Rosa P F S 
Published: August 2022

Abstract
Spin-triplet bulk superconductors are a promising route to topological superconductivity, and UTe2 is a recently discovered contender. The superconducting properties of UTe2, however, vary substantially as a function of the synthetic route, and even nonsuperconducting single crystals have been reported. To understand the driving mechanism suppressing superconductivity, we investigate UTe2 single crystals grown close to the nonsuperconducting boundary (growth temperature ∼710 ∘C) through a combination of thermodynamic and x-ray diffraction measurements. Specific heat measurements reveal a sharp decrease in the superconducting volume and a concomitant increase in the residual specific heat coefficient close to the nonsuperconducting boundary. Notably, these crystals are inhomogeneous and show an apparent double transition in specific heat measurements, similar to samples grown at much higher temperatures (∼1000 ∘C). Our single crystal x-ray diffraction measurements reveal that there are two important tuning parameters: uranium vacancies and the atomic displacement along the c axis, which shows a twofold increase in samples with a reduced superconducting volume. Our results highlight the key role of local disorder along the uranium-uranium dimers and suggest that the apparent double superconducting transition is more likely to emerge close to the superconducting limits of UTe2.

Published: August 2022

AbstractSummaryHNOXPred is a webserver for the prediction of gas-sensing heme-nitric oxide/oxygen (H-NOX) proteins from amino acid sequence. H-NOX proteins are gas-sensing hemoproteins found in diverse organisms ranging from bacteria to eukaryotes. Recently, gas-sensing complex multi-functional proteins containing only the conserved amino acids at the heme centers of H-NOX proteins, have been identified through a motif-based approach. Based on experimental data and H-NOX candidates reported in the literature, HNOXPred is created to automate and facilitate the identification of similar H-NOX centers across systems. The server features HNOXSCORES scaled from 0 to 1 that consider in its calculation, the physicochemical properties of amino acids constituting the heme center in H-NOX in addition to the conserved amino acids within the center. From user input amino acid sequence, the server returns positive hits and their calculated HNOXSCORES ordered from high to low confidence which are accompanied by interpretation guides and recommendations. The utility of this server is demonstrated using the human proteome as an example.Availability and implementationThe HNOXPred server is available at https://www.hnoxpred.com.Supplementary informationSupplementary data are available at Bioinformatics online.

AbstractSerum samples of 20 hospitalized coronavirus disease 2019 (COVID-19) patients from Brazil who were infected by the earlier severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineages B.1.1.28 and B.1.1.33, and by the variant of concern (VOC) Gamma (P.1) were tested by plaque reduction neutralization test (PRNT90) with wild isolates of a panel of SARS-CoV-2 lineages, including B.1, Zeta, N.10, and the VOCs Gamma, Alpha, and Delta that emerged in different timeframes of the pandemic. The main objective of this study was to evaluate if the serum of patients infected by earlier lineages was capable to neutralize later emerged VOCs. We also evaluated if the 4-fold difference in PRNT90 titers is a reliable seropositivity criterion to distinguish infections caused by different SARS-CoV-2 lineages. Sera collected between May 2020 and August 2021 from the day of admittance to the hospital to 21 days after diagnostic of patients infected by the two earlier lineages B.1.1.28 and B.1.1.33 presented neutralizing capacity for all challenged VOCs, including Gamma and Delta. Among all variants tested, Delta and N.10 presented the lowest geometric mean of neutralizing antibody titers, and B.1.1.7, presented the highest titers. Four patients infected with Gamma, that emerged in December 2020, presented neutralizing antibodies for B.1, B.1.1.33, and B.1.1.28, its ancestor lineage. All of them had neutralizing antibodies under the level of detection for the VOC Delta. Patients infected by B.1.1.28 presented very similar geometric mean of neutralizing antibody titers for both B.1.1.33 and B.1.1.28. Findings presented here indicate that most patients infected in early stages of COVID-19 pandemic presented neutralizing antibodies capable to neutralize wild types of all later emerged VOCs in Brazil, and that the 4-fold difference in PRNT90 titers is not reliable to distinguish humoral response among different SARS-CoV-2 lineages.
