Conditional probability framework for entanglement and its decoupling from tensor product structure
Authors: Basieva Irina , Khrennikov Andrei 
Published: August 2022

Abstract
Our aim is to make a step toward clarification of foundations for the notion of entanglement (both physical and mathematical) by representing it in the conditional probability framework. In Schrödinger’s words, this is entanglement of knowledge which can be extracted via conditional measurements. In particular, quantum probabilities are interpreted as conditional ones (as, e.g., by Ballentine). We restrict considerations to perfect conditional correlations (PCC) induced by measurements (‘EPR entanglement’). Such entanglement is coupled to the pairs of observables with the projection type state update as the back action of measurement. In this way, we determine a special class of entangled states. One of our aims is to decouple the notion of entanglement from the compound systems. The rigid association of entanglement with the state of a few body systems stimulated its linking with quantum nonlocality (‘spooky action at a distance’). However, already by Schrödinger entanglement was presented as knotting of knowledge (about statistics) for one observable A with knowledge about another observable B.

Published: August 2022

Abstract
The article deals with the application of automated control systems for mechanical quantities and vibration diagnostics for draught-blowing machines of boiler units of thermal power plants of medium power in order to ensure their environmental and industrial safety. Draft blowers are technical devices operated at hazardous production facilities of thermal power plants as vibration control and monitoring systems in accordance with technical requirements. The requirements for the scope of control and measurement of technological and electrical parameters of draft machines, such as bearing temperature, medium temperature, discharge and suction pressure, electric motor currents, are considered. The authors propose two options for solving the problem of organizing monitoring of draft machines for thermal power plants. To determine the possibility of organizing a full-function monitoring of draft machines, a method for expert analysis of the technical and metrological characteristics of automated systems for monitoring vibration and mechanical quantities is proposed.

Abstract
Digitalization of the Russian economy has been increasingly introduced into the Russian economy in recent years, covering an increasing number of industries and processes. In the modern information world, in the presence of such a volume of various data that require constant updating, processing and monitoring, it is impossible to do without such tools as digital technologies. The Russian agro-industrial complex has been developing quite steadily in recent years and has a tendency of further growth. This, to a large extent, contributes to the modern policy of the state, carried out through the relevant departments and orientation to the international conjuncture. The growth of production in the main branches of the agro–industrial complex in the previous year was: in crop production - 7.1%, in animal husbandry – 3.3%. In the future, it is planned to accelerate the pace of development in the agro-industrial complex due to the integrated introduction of digitalization in agriculture, which is supposed to be provided through state support measures. During the past year, the state allocated 309.1 billion rubles for the implementation of programs for the development of agriculture. Issues of agricultural development are constantly being paid attention at the meetings with the Board of the Ministry of Agriculture in Russia, which is necessary in the framework of ensuring food security in the country. The purpose of this article is to consider the main directions for the development of the agro-industrial complex, analyze the dynamics for the introduction of digital technologies and compares the pace of digitalization with other countries and different regions. It is also necessary to consider the possible advantages for the transformation of agriculture and the agro-industrial complex as a whole and the possibility of acquiring competitive advantages of the industry. It is also necessary to consider which digital technologies, in which processes and in what sequence should be implemented at the enterprises of the agro-industrial complex in the Krasnoyarsk Region.

Published: August 2022

Abstract
This article presents an experiment on drying mulberry silkworm type 3 cocoons using universal infra-red drying equipment. Three types of cocoons, Bombyx mori, Antheraea pernyi and Antheraea mylitta, were used as an object of research. A universal (convection) drying equipment with an infrared heat source was used, which allows a fairly wide variation of the operation and load parameters (chamber temperature °C and air speed up to ±0 °C). t1 = 70 °C, air velocity up to ω = 0,7 m/sec and the drying load volume Pc = 0,5 kg/m2. The parameters that ensure the maximum intensity of the drying process while maintaining the quality properties are: coolant temperature in drying equipment within t1 = 65 …75 °C and the air velocity, which gives the best performance with the lowest possible losses in the ranges of ω = 0,6 − 0,7 m/sec.

Abstract
In the manuscript we described the results of the primary study of the state of environmental health in the protected forest park “Pine Grove” (Yoshkar-Ola, Russia). We found out the vital status 233 organisms of 10 important tree species for coniferous-deciduous forest. Severe damage was recorded in the plantings of Picea X fennica, Larix sibirica. We found drying of branches mainly in coniferous trees due to stagnation of flood water as a result of poorly carried out drainage works. FA index of the leaf plate of Betula pendula trees from the forest reached a value of 0.39. With IFA scale, the vitality of B. pendula is assessed as optimal, which indicates optimal environmental conditions in the territory of «Pine Grove».
A possible medieval recycling technique – smelting iron using hammerscale
Authors: Thiele Á , Török B 
Published: August 2022

Abstract
Hammerscale is a common by-product of the forging process of iron and it may appear in a large amount in the ancient smithy workshops as well. Its recycling (i.e. re-smelting) in early bloomery furnaces might have been an economical and reasonable process, although it is not known whether it works or not, and also there is no archaeological evidence for this technique. In our recent investigation, flaky hammerscale was smelted using the copy of the 8-10th century embedded furnaces of the Avars and the conquering Hungarians. The resulting bloom was processed to a billet and its chemical composition was further examined. Hammerscale proved to be an excellent raw material for the early bloomery iron smelting technology: good iron yield could be achieved due to the high reaction surface and iron content. Moreover, the extracted bloomery iron had low carbon content and had a very low amount of undesirable impurities, e.g. P, As. Cu, S. etc.
Design and manufacture of closed die multi-axial forging tool
Authors: Juhász Zs , Bíró T , Renkó J B 
Published: August 2022

Abstract
In the last decades many solutions were developed to achieve multi-axial forging. Outstanding among these is the two-way process that can be implemented on the Maxstrain unit of the Gleeble thermophysical simulator. Although the experiments performed on the Gleeble system were well suited for characterize mechanical models, this system had some serious issues, such as the outflow of material from the forging zone. To solve these problems, a new forming tool was designed, in which the total volume of the workpiece is deformed, and the shanks used for fastening can be omitted.
Numerical Investigation of Hot Roll Bonding of Multilayer Sheet Metal
Authors: Jemal D E , Zsolt L , Máté S 
Published: August 2022

Abstract
The roll bonding process of the sandwich sheet is a preferable production method to manufacture multilayer sheets and it needs clear investigation because some industrial parts cannot fulfill all of the requirements by single-layer material. In this study, a theoretical model of roll bonding has been reviewed and hot sandwich rolling processes with different plate thickness and flow stress were numerically investigated. The contact pressure-dependent bonding properties in the deformation zone were defined. Then, the liner thickness and reduction ratio are important parameters to determine the total deformation zone. When the thickness of the liner becomes large, unbonded length of deformation can be a serious problem and at the same time, the good bonding strength can be found at a higher reduction ratio of the thinner liner.
The role of friction in the sheet metal forming numerical simulation
Authors: Carvalho L. A. , Lukács Z. 
Published: August 2022

Abstract
This study aims to fulfil the current needs of the sheet metal forming industry by designing a practical, fast, efficient and low-cost rig to describe friction. Nowadays, the technological tool design process of sheet metal components is unthinkable without the application of finite element modelling. Despite the importance of friction for the metal forming processes, it is frequently overlooked in metal forming simulations. Many manufactures are demanding for a more accurate description of tribology. Therefore, there are some relatively simple devices, based on traditional tests that have been presenting high accuracy on friction prediction. Until now, no universal method for determining the coefficient of friction has been established. This is due to the variety of geometry on the contact between the tool and the deformed material, as well as the presence of various stress and strain states in different areas of the draw piece during different moments of the sheet metal forming. This paper presents the first friction results obtained with the new equipment built at the University of Miskolc. For the analyses it was applied 2 different velocities and 5 different pressures. The results were analysed using the analyses of variance.

Authors: Berczeli M , Hatoss B , Kókai E 
Published: August 2022

Abstract
Innovative surface technology processes offer a wide range of surface preparation options, allowing engineers to make major changes to the properties of products. Surface modification can also improve the quality and the strength of the bond created by technologies such as bonding, painting, coating, sealing and other adhesion. By activating molecular groups on the surface, wetting properties can be improved, while altering the microtopography of the surface can create roughness and texture. Surface modification suitable for industrial conditions in cold plasma surface modification. The the wetting boundary angles are measured with ethylene glycol and distilled water, and the results are used to calculate the surface free energy of the modified surface in mN/m according to Fowkes surface free energy theory. The demonstration of adhesion improvement of specimens with good wetting surfaces should be carried out by a series of bonding experiments, showing the changes in strength due to surface treatment. In addition, the technical advantages obtained by modifying the topography can be characterised by examining the separated surfaces.

The plastic strain and the rolling direction dependence of the traditional and the biaxial r-values
Authors: Hoffmann Á Zs , Béres G J 
Published: August 2022

Abstract
The Lankford number (i.e. r-value) has long been used as a key parameter in the science of sheet metal forming, for the mathematical description of plasticity. The traditional way of thinking is that this value is a constant in a given direction, and the definition is recommended at Ag-1 % plastic strain. In this study we focused on the evolution tendency of r-value in the function of the plastic strain, in different loading directions. Two automotive thin sheets, DC04 and DP1000 were examined by uniaxial tensile tests and compression tests to investigate both the traditional and the biaxial r-values. The axial and the transverse deformations during the tensile tests were applied under continuous process monitoring with a touchless video extensometer. The compression tests were carried out intermittently, i.e. the tests were stopped after given forces, and the thickness as well as the diameters were measured parallel and perpendicular to the rolling direction. Our results show that the evolution of the traditional r-value is clearly shown for both materials, and its value is given here by linear and polynomial functions. Besides, the changing characteristic of the r-value as a function of deformation does not show a trend with respect to the rolling direction. The biaxial r-value can be well-defined by compression tests despite the small thickness, and the results are less dependent on friction.
Investigation of nickel coated steel tapes welded joints
Authors: Hareancz F , Sinka T 
Published: August 2022

Abstract
Nickel-plated steel tapes are primarily developed for battery production. The aim of these developments was to provide all battery cell cases with good contact resistance and high corrosion resistance, thus increasing their durability. When individual battery cells are packaged, the electrical connection is also mostly made with nickel-plated plates. Welding and soldering are the bonding technologies used to make the connections between the plates, but the advantages mentioned above may vary when making these connections. To our knowledge, lasers with diode beam sources are the most efficient and are becoming more and more suitable for a wide range of applications as the technology develops. The aim of our investigations is to investigate the quality of joints made with low power diode lasers with different parameters from a strength and metallographic point of view.

Abstract
Intravitreal injection of chemotherapy drugs for intraocular retinoblastoma, for the prevalent pediatric malignancy treatment with the side effects of severe infection. This study tried to synthesize the novel approach to deliver Melphalan to the vitreous cavity through the cornea to increase drug efficacy with non-invasive effects. For this purpose, lauric acid-grafted chitosan-alginate and chitosan-alginate loaded by Melphalan nanoparticles were fabricated. Fourier-transform infrared spectroscopy (FTIR) and x-ray diffraction (XRD) were the basic characterizations of chitosan modification. Scanning electron microscopy (SEM) and dynamic light scattering (DLS) are the other assessments of synthesized nanoparticles. Drug encapsulation and in vitro release were studied using UV-spectroscopy, also ex vivo and in vivo corneal permeation was studied using Franz diffusion cell, fluorescence microscopy, and in vivo animal imaging. FTIR and XRD confirm the successful grafting of lauric acid and spherical shape with the average size of 50 nm and 80 nm observed for modified and chitosan-alginate nanoparticles respectively. In the release study, encapsulation efficiency of 98% with sustained drug release of 80% for 100 h with the Fickian drug diffusion mechanism was reported. Ex vivo corneal permeation exhibited an improved drug penetration rate in the sample of lauric acid-grafted-chitosan-alginate nanoparticles with the results of 5.8 times higher than chitosan-alginate nano-carriers and 15.5-fold compared to drug solution. Also, in vivo study shows that the designed nanoparticles containing Melphalan reached the vitreous cavity with high efficacy. Current investigations illustrate the novel Melphalan delivery with sustained behavior through the cornea with the high potential of corneal layer penetration for retinoblastoma management.
Nonlinear anomalous Hall effects probe topological phase-transitions in twisted double bilayer graphene
Authors: Chakraborty Atasi , Das Kamal , Sinha Subhajit , Adak Pratap Chandra , Deshmukh Mandar M , Agarwal Amit 
Published: August 2022

AbstractNonlinear anomalous (NLA) Hall effect is the Berry curvature dipole induced second-order Hall voltage or temperature difference induced by a longitudinal electric field or temperature gradient. These are the prominent Hall responses in time-reversal symmetric systems. These band-geometry induced responses in recently realized twistronic platforms can probe their novel electronic band structure and topology. Here, we investigate the family (electrical, thermoelectric, and thermal) of second-order NLA Hall effects in the moiré system of twisted double bilayer graphene (TDBG). We combine the semiclassical transport framework with the continuum model of TDBG to demonstrate that the NLA Hall signals can probe topological phase transitions in moiré systems. We show that the whole family of NLA Hall responses undergo a sign reversal across a topological phase transition. Our study establishes a deeper connection between valley topology and nonlinear Hall effects in time-reversal symmetric systems.

Abstract
Photocatalytic inactivation has been proved to be an effective strategy to eliminate pathogenic bacteria in water. Herein, a novel 0D/2D p-n heterojunction of Ag2S-anchored P-doped g-C3N4 (Ag2S/PCN) were constructed by a simple two-step process coupling one-pot calcination and ultrasonic-assisted synthesis. The photocatalytic performance of as-prepared Ag2S/PCN composites was investigated by inactivating multidrug-resistant E. coli under visible light irradiation. The results indicated that Ag2S/PCN-5 possessed outstanding photocatalytic inactivation activity and superior stability, which could completely inactivate 7.0 log E. coli cells within 60 min. The enhanced photocatalytic activity of Ag2S/PCN-5 was mainly attributed to the elevated visible-light response and improved production and transfer of photoexcited charges. In addition, the free radicals trapping experiments results revealed that h+ and •O2
− were predominantly responsible for the efficient inactivation activity. Finally, according to the 0D/2D structure and energy band configuration analysis, the enhanced p-n type heterojunction photocatalytic inactivation mechanism of Ag2S/PCN was discussed in detail.

Abstract
Climate change is considered as a potential threat to sustainability of agriculture in India. Considering the importance of agriculture in the pursuit of the India’s development objectives, including the Sustainable Development Goals of the United Nations, understanding possible impacts of climate change on productivity of major food crops in the country assumes importance in developing appropriate policies and programmes for agricultural technology development and transfer in general and for climate change adaptation in particular. Such an understanding at a scale where most of the development planning is done will be more useful in policy planning. This paper analysed climate change impacts at district level for major food crops using the district level climate projections for two time periods viz., mid-century (2021–2050) and end-century (2071–2098). Yields of most crops are projected to decrease in a majority of districts during mid-century period. The yield impacts are deeper and wider during end-century period. The yield impacts are relatively smaller and even positive in case of rapeseed & mustard and soybean. Some of the policy implications emerging from this study are: (i) Efforts are to be targeted and prioritized in the districts where the yields are likely to suffer more (ii) Concerns related to abiotic stress, especially those related to heat/temperature stress, need more attention in crop improvement and natural resource management programmes and (iii) Considering the dimension of climate change along with other bottlenecks to sustainable agriculture in the research and development process is a desirable way of mainstreaming climate change in to economic development programmes.
