Explicit Representation of the Euler and Navier – Stokes Equations of Incompressible Fluid with Reduced Dimensionality in Integral Form
Authors:   Business, Zaytsev Maksim , Akkerman Vyacheslav ,   West Virginia University
Published: April 2022

In this paper, we have obtained “stationary” systems of integraldifferential equations, which are consequences of the non-stationary Euler and Navier - Stokes equations of an incompressible fluid, and for which there are no time derivatives. If we set a correct problem for them, then we can determine the entire non-stationary flow in the volume without solving the nonstationary problem. It is enough to specify time-varying data only on some surface of this stream. The method of reduction of overdetermined systems of differential equations, proposed earlier by the authors, is used. In this method, in the case of a successful choice of the additional constraint equation, the overdetermined systems of differential equations are reduced to PDE systems of dimension less than that of the original PDE systems. The Euler and Navier-Stokes equations themselves act as the constraint equations, and the dimension is reduced for the integral equations, which are obtained using the Helmholtz theorem on the expansion of an arbitrary vector field into vortex and potential components. The peculiarity of this work lies in the fact that all the equations reduced in dimension are obtained in an explicit form, in contrast to the previous works of the authors, where up to 200–300 equations with reduced dimensions were proposed. In reduced systems of integral-differential equations, there is integration over space, therefore, reduction over spatial variables by given method is impossible. If this method is generalized a little, then we can obtain a reduced system of integral equations, where the unknowns have no derivatives with respect to space, but integration over space remains. Non-stationary new integral equations are also obtained, which determine the evolution of the flow. In Appendices A and B, sufficient conditions for the correctness of the reduced system of integral-differential equations are derived. Conditions are found under which the Euler equations follow directly from these reduced equations. It is shown how the time-varying data on some surface of this stream should be related. The change of variables, which is used in the reduction of the Navier - Stokes equations, is also investigated he resulting integral equations can be used to study complex vortices in the atmosphere. For example, if devices measuring data on its surface are installed on a flying object, then, knowing the vorticity profile ω0(r) at a certain moment in time, it is possible, by solving these equations, to track vortex activity at a distance from this object in real time.

This work is a part of the project on creation the linguistic corpus of the fund “Mikhailovsky stanitsa ataman” documents. This fund contains historically valuable administrative documents of the Don Cossacks Army of the 18th-19th centuries, stored in the State Archives of the Volgograd Region. To introduce it to scientific society, a lot of preliminary work to digitize them was done by group of scientists from Volgograd State University headed by Professor O.A. Gorban. In their current form, these documents are suitable for computer processing. The only significant problem is outdated vocabulary and graphics, but it was generally solved in our previous works. At the current stage, the main task is to develop the technical and software parts of the corpus. In fact, this means the creation of an “engine” for a document corpus, that is, software for storing a database of marked-up texts, executing queries to this database, and also providing user-friendly interface that does not require special IT-skills. At the same time, in the process of working on the previous tasks, we decided to integrate the document markup tool into the general corpus software. Thus, the present work is devoted to the development of a REST service that allows you to perform automated morphological analysis of texts, save a special form of processed documents in a database, search in database by a query with morphological features of elements in the texts. The software also provides a function for manual correction of errors that occur in automated analysis of Old Slavonic texts with obsolete characters.

A two-dimensional model of the flow of the gas-dust interstellar medium in the vicinity of the spiral arm of the galaxy is constructed. The flow in a vertical plane transverse to the disk plane is considered. The effects of nonadiabatic flow (volumetric heating and cooling of the gas by radiation) are taken into account. The balance of heating and cooling ensures the coexistence of two phases, cold parsec-sized clouds of atomic hydrogen and warm intercloud gas. The consideration includes polydisperse dust, represented by three fractions of particles of different sizes and masses. Dust particles have finite inertia, their movements do not exactly repeat the movement of gas. Turbulence in the disk and in the spiral arm is also taken into account. Models are considered that use different combinations of the location of turbulence sources in the disk and/or in the arm. The main results obtained by the methods of computer hydrodynamic modeling are as follows. Clouds undergo significant transformations as they pass through the spiral arm. A significant part of the clouds is absorbed into a thin dense cloud layer, which extends in a spiral arm along the equatorial plane in the vicinity of the center of the arm and has a size of approximately half the width of the arm. A smaller part of the clouds passes without destruction or with partial destruction through the sleeve, experiencing strong deformations along the way. The small-scale cloud component is partially restored under the action of turbulence, which perturbs the extended cloud layer inside the arm and partially destroys it into separate fragments. A wedge-shaped galactic shock wave is formed on the rear side of the arm with respect to the incoming gas flow, attached to the rear edge of the extended cloud layer. A flow limited by a shock wave has the character of a jet that performs quasi-periodic transverse oscillations. The reason for the oscillations, apparently, is the instability of the shear flow, since tangential discontinuities are formed inside the jet along the flow and at a small angle to the shock fronts. Dust particles are dragged by turbulent eddies and carried to heights of 150–200 pc above the disk plane, which naturally explains the existence of chaotic filamentous dust structures extending above the galactic disk to heights of several hundred parsecs. The grains of dust are distributed differently inside the vortices. Dust grains with sizes of 0.01-0.1 μm cluster more easily than larger dust grains with a radius of 1 μm. Turbulence serves as a mechanism to effectively trap dust particles on the front side of the spiral arm. Modeling shows that dust lanes are more pronounced on the front side of the arm.

Attestation of information objects (IO) is an important stage in the implementation of information protection system at enterprise, organization or state body. In essence, attestation is a set of measures carried out at the IO to check the reliability of the implemented information protection system, as a result of which compliance with certain requirements of the state regulator in the field of technical information protection (FSTEC of Russia) is confirmed. The attestation process is necessary as a stage preceding the beginning of processing of the protected information, which provides for comprehensive (certification) tests of the protected IO in order to assess them. Such assessment is carried out in terms of compliance of the set of means and security measures used in IO to the put forward level of protection and should be carried out under real operating conditions of the system. The “Certificate of Conformity” obtained as a result of attestation gives the right to processes of information processing with the established level of confidentiality for the period specified in the certificate. This work examines various aspects of attestation of information object, the structure of attestation tests, legal framework, and organizational issues. The basic stages of attestation tests, and a list of necessary reporting documentation formed at various stages of tests are allocated. The concept of evaluation of attestation tests’ efficiency is considered and the question of the approach’s realization to increase the efficiency of information object’s attestation of information security requirements is raised.

Published: April 2022

The article explores the features and methods of sending SMS traffic using the API (Application Programming Interface), discusses the parameters and API functions for sending Short Message Service (SMS) messages, also analyzes of causes of the loss of the traffic and the options for subsequent prevention of this loss. The scheme of the interaction between the Short Message Service Center (SMSC) and ordinary subscribers is considered. The popular protocol Short Message Peer-to-Peer (SMPP) was used as the protocol under study, capable of transmitting any type of messages, and is an open protocol in the telecommunications industry, which is designed specifically to provide a flexible interface for exchanging SMS messages between SMS applications, platforms, routers and short message service centers. The analysis of the captured traffic was carried out using special software – Wireshark, that allows to apply filters to track the protocols that are used for SMS transmission. Various types of losses in telecommunication networks are considered and a correlation is established with the factors which affect the communication channel. The results obtained can be used to develop an algorithm for searching for lost packets that occur when traffic passes through switching nodes. This model is able to improve the quality of service for telecom operators.

The purpose of this work is to study the features of the properties of a plane wave incident on a layered and periodic medium with an embedded defective layer. The relevance of the study of photonic crystals is due to the fact that this area of modern materials science is widely developing in the world of science. A confirmation of the large growth in development is the specificity of the versatile application and implementation of photonic crystals. For example, it becomes possible to create digital computing devices based on photonics. The possibility of creating new types of lasers with the lowest lasing threshold, high-efficiency LEDs, optical switches, and light guides is also not ruled out. The uniqueness of photonic crystals lies in their structure, the properties of which have a periodic change in the refractive index. These crystals, due to their peculiarity, do not transmit light with a wavelength comparable to the time of the crystal structure, since they remain transparent for a wide range of electrical radiation. Formulas for the energy reflection and transmission coefficients for layered, periodic media are derived and calculated. A basic component of a computer program for calculating the reflection and transmission coefficients of layered nanostructures has been developed. An analysis was made of an interstitial layer, in this case a defect, in a periodic layered structure such as a photonic crystal.

Several years ago, there were no effective methods for treating bile tract structures, but the situation changed significantly with the invention of the stent. The use of biliary stents for the treatment of mechanical jaundice made it easier to remove them from the body. However, it was not possible to stop the appearance of restenosis and thrombosis. To prevent such complications, drug coatings, which are a polymer matrix with drugs introduced into it, began to be applied to the stent surface. At present, despite the rather wide range of drug coatings, the search for new biodegradable carrier polymers that provide a high-quality and inexpensive coating of biliary stents remains relevant. The paper considers the technology of creating a new ultra-thin drug coating for these stents based on polyvinylpyrrolidone with the addition of doxorubicin and carbon nanotubes. The invention proposes the use of carbon nanotubes based on their unique sorption properties. Steps of application of drug coating on stent surface and selection of optimal content of carbon nanotubes in coating composition are described. Theoretical studies of the interaction processes of drug coating components using the quantum-chemical method MNDO have been carried out. GAMESS, Gaussian, GaussView software packages were used for calculations.

Introduction:The active learning process is certainly one of the most complex challenges in dental education. It is essential for the development of critical thinking and clinical skills. There is evidence of the need for teacher professionalization, but there is scarce literature reporting on the positive changes in the teaching profession based on such professionalization. The aim of the present study is to explore the experiences of the pedagogical performance of professionalized educators in dentistry. Material and Methods: A qualitative study was conducted using a design based on content analysis. The sample was selected for convenience and included dentists who have completed a master's degree in teaching in higher education, who were part of the teaching staff of a dental university program and with a career experience of at least 5 years. Semi-structured interviews were conducted, with three initial dimensions: Teaching Career, Motivation for Teacher Professionalization, and Impact on the teaching-learning process. The interviews were verbatim transcribed and content analysis was performed by the researchers using data triangulation. The research was approved by the research and ethics committee. Results: Six categories were established: Generational clash, Motivations to practice teaching, Motivations to professionalize teaching, Competences acquired after professionalization, Effects of professionalization in the classroom context, and Shortcomings of the professionalized educator. Conclusion: Professionalized dental educators show comprehensive improvements in their performance. They have developed practical competences for the specific needs of the courses they give.
First Do No Harm: Legal Principles Regulating the Future of Artificial Intelligence in Health Care in South Africa
Authors: Donnelly Dusty-Lee
Published: April 2022

What sets AI systems and AI-powered medical robots apart from all other forms of advanced medical technology is their ability to operate at least to some degree autonomously from the human health care practitioner and to use machine-learning to generate new, often unforeseen, analysis and predictions. This poses challenges under the current framework of laws, regulations, and ethical guidelines applicable to health care in South Africa. The article outlines these challenges and sets out guiding principles for a normative framework to regulate the use of AI in health care. The article examines three key areas for legal reform in relation to AI in health care. First, it proposes that the regulatory framework for the oversight of software as a medical device needs to be updated to develop frameworks for adequately regulating the use of such new technologies. Secondly, it argues that the present HPCSA guidelines for health care practitioners in South Africa adopt an unduly restrictive approach centred in the outmoded semantics of telemedicine. This may discourage technological innovation that could improve access to health care for all, and as such the guidelines are inconsistent with the national digital health strategy. Thirdly, it examines the common law principles of fault-based liability for medical negligence, which could prove inadequate to provide patients and users of new technologies with redress for harm where fault cannot clearly be attributed to the healthcare practitioner. It argues that consideration should be given to developing a statutory scheme for strict liability, together with mandatory insurance, and appropriate reform of product liability pertaining to technology developers and manufacturers. These legal reforms should not be undertaken without also developing a coherent, human-rights centred policy framework for the ethical use of AI, robotics, and related technologies in health care in South Africa.

Every phenomenon or custom has a societal history attached to it, how it develops, how it becomes suitable to people in universal and why it continues even now. There are various traditions and customs, which thwart people from realizing that bride trafficking, is a crime. History speaks about various instances of traditions and customs which are similar to the crime of bride trafficking but because they are time immoral they have got certain level of acceptance by different societies. The custom, traditions and usages bring acceptability to any practice even per se the practice is illegal and same we can find in case of Bride price tradition.
Criminal Intelligence in Criminal Proceedings
Authors: Vasko A.
Published: April 2022

The issue of the use of intelligence (or also operational-search) information in criminal proceedings is currently relatively little researched and developed. We think that this is also because intelligence and operational search are associated with secrecy and a certain aura of “mystery” for the general public and, to some extent, for the majority of the professional legal community. The role of the intelligence services in the times of socialist Czechoslovakia also plays a role, and a significant one.

Addressing current security challenges associated with manifestations of international terrorism, extremism and organized crime requires the acceptance of new, even non-traditional, approaches by law enforcement agencies. In this paper, we present our opinion regarding the extent of the possible use of intelligence (or operational search) information in criminal proceedings.

International Legal Framework for the Application of Genetic Technologies: Main Features and Issues Open for Discussion
Authors: Gazina N. I. , Teymurov E. S. , Zakharova L. I.
Published: April 2022

The objective of the present article is to determine the specific characteristics of the established international legal framework for the application of genetic technologies and to identify general guidelines that influence states’ policies in this area.

Genetic technologies evolve rapidly, raising a number of ethical and legal issues and directly affecting human rights. At the universal level, there is still no international treaty containing uniform rules in this field. At the regional level, the experience of the Council of Europe deserves further study. National approaches to the legal regulation of applying genetic technologies differ since States retain a great deal of discretion in regulating these issues.

Though the Council of Europe Member States enjoy a margin of appreciation in regulating the use of genetic technologies, a number of common distinctive features underlying the international legal framework in this area can still be singled out. These are informed consent, prohibition of reproductive human cloning, prohibition of germ line modification with certain exceptions. They arise primarily from the Oviedo Convention, the Protocols thereto and the ECtHR practice. Soft law documents adopted at the UN, UNESCO and the Council of Europe contribute to the process of their formation, too, but to a lesser extent. The efforts undertaken at the European and universal level shape modern international legal regulation in the field and set up the course of action for States to follow.
KOSTYCHEV-ORLOV EQUATION AND FIRST MATHEMATICAL MODELS OF HUMUS DYNAMICS
Authors: Glagolev Mikhail Vladimirovich
Published: April 2022

This work is a report written at the suggestion of the talented Soviet scientist V.V. Zeleneva in 1986-1987, when the author was a 4th year student at the Faculty of Soil Science, Moscow State University. M.V. Lomonosov.
The report analyzes the equation proposed at the dawn of soil science by P.A. Kostychev for the maximum level of humus accumulation (and later modified by D.S. Orlov). It is shown that from the point of view of mathematics, the Kostychev equation is meaningless and has no solution at all. Improved by Orlov, it already has solutions, but it seems that it still cannot be effectively used. In this regard, various types of those mathematical models of humus dynamics are considered, which were used by specialists in soil science and ecology.
Quantitative evaluation of defects based on the characteristics of the induced eddy current field
Authors: Yao Wenqing , Yang Yuan , Jiang Feng , Di Xinyu , Tao Li , Geng Long
Published: April 2022

A quantitative evaluation method for determining the shape, length and depth of surface defects is proposed for the purpose of non-destructive testing (NDT) and evaluation of metal materials. The COMSOL Multiphysics finite element software is used to calculate and analyse the eddy current
magnetic field and the influence of the geometric parameters of defects on the spatial three-dimensional magnetic field distributions are studied. The results show that the shape of the surface defect can be judged from the measurement result of the x-Bx curve. The quantitative
analysis of the crack length is realised according to the corresponding position of the peak (trough) of surface magnetic field Bz . The depth of the crack can be inversely calculated by the quantitative relationship between the trough depth of Bx (or the peak value of
Bz) and the crack depth. Therefore, this method provides convenient and contactless detection technology in which the characteristic quantities corresponding to the defect parameters are independent from each other to improve the accuracy of defect evaluation.

Published: April 2022

In order to quickly and comprehensively detect residual stress, microcracks and other damages in ferromagnetic materials, this study developed an integrated magnetic non-destructive testing system with changeable magnetic field excitation based on anisotropic magnetoresistive (AMR)
sensors. The system integrated magnetic memory detection, magnetic flux leakage (MFL) detection and magnetic Barkhausen noise (MBN) detection and was used to perform detection experiments on a 45# steel test-piece with precast residual stress zones and cracks in different directions. The experimental
results showed that the proposed system can detect residual stress in a ferromagnetic test-piece, identify microcrack defects of different angles and quantitatively evaluate the residual stress. This paper provided a useful reference for the comprehensive evaluation of damages in ferromagnetic
materials.
The Role of Psychosocial Maturity and Race in Juvenile Transfer Decisions
Authors:   , Schiedel Rebecca Lynn , Heilbrun Kirk
Published: April 2022

Although young offenders are considered to be categorically less psychosocially mature than adult offenders, judges have limited empirical guidance as to how to appraise maturity or factor this information into judicial decisions. Earlier research on this topic indicates that judges focus more on indicators of criminal sophistication (e.g., offense severity) when determining appropriate dispositions of juveniles, but questions remain about the relative influence of psychosocial maturity, particularly in cases of less severe offenses. This study examined how judges weigh information indicative of psychosocial maturity when making decisions regarding treatment for juveniles, as well as how this information may be understood differently for adolescents of different races. Participating judges (N = 72) viewed one of four vignettes about a hypothetical juvenile, which varied in regard to psychosocial maturity and race. Participants then indicated whether they would transfer the juvenile to criminal court, and rated the degree to which the juvenile was in need of rehabilitation and three different justifications for punishment. Results showed that psychosocial maturity did not directly influenced judges' transfer decisions, but there was a significant indirect effect through perceived risk of reoffending on likelihood of recommending transfer. The potential implications of these findings in the context of the juvenile justice system are discussed.

The Sharia Funding, Savings, and Loans Cooperative (KSPPS) BUEKA Walidah Mulia (BWM) is a national sharia secondary cooperative established by the Aisyiyah Central Executive Labor Economic Council. Each provincial secondary cooperative has three primary sharia cooperatives. KSPPS BWM is the parent of national cooperatives as a strategic driver in reviving and assisting secondary/primary cooperatives. The problem faced by KSPPS BWM is that the capacity of human resources (managers) in organizational governance is not standardized. The purpose of empowering KSPPS BWM is to increase the capacity of managers in cooperative governance according to Cooperative Governance Standards. The applied methods in the program were socialization, education, focus group discussions (FGD), mentoring, monitoring, and evaluation. The results of the empowerment show that the capacity of KSPPS BWM cooperative managers in terms of knowledge and skills of standard cooperative management increases. The implication of the service program is that the performance of KSPPS BWM cooperative management increases and is able to carry out the control function to better managed secondary/primary cooperatives.

Authors: Cavallo Eduardo A. , Galindo Arturo , Nuger Victoria , Powell Andrew
Published: April 2022

Economic growth in Latin America and the Caribbean was stronger than expected in 2021 but waned at the start of 2022. High commodity prices due to the war between Russia and Ukraine will provide a boost to exporters, while imposing significant costs on commodity importers and pushing up inflation across countries. The ongoing conflict, together with policy normalization in advanced economies, carries significant risks for the region. Volatility in financial markets could depress investment and bring down growth further. Policymakers need to take urgent measures to boost inclusive growth. As minor fixes are unlikely to result in notable benefits, governments should consider more fundamental resets of policy frameworks. This report analyzes growth prospects, monetary policy, and external and financial sectors. The recommendations stress the need for a new architecture for both fiscal and labor market policies. Policymakers should seize the window of opportunity provided by the COVID-19 crisis and global security concerns to improve the outlook for the region.
