Authors:   Academy of Civil Protection of the Ministry of the Russian Federation for Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters, Tsybakov Dmitry L.
Published: January 2023

Relevance. The institution of parliamentary monarchism, in the presence of contradictory attitudes of various social communities towards it, remains one of the typical components of modern democratic systems. However, in the conditions of post-industrial society, cardinal transformations of parliamentary monarchies in European countries are taking place, which leads to their mimicry under the influence of such factors of social relations as postmodernism and globalization. A political analysis of the noted problem is presented relevant in view of the need to clarify the signs and parameters of democratic institutions in the political systems of modern European states. The purpose of the scientific article is to consider the prospects for the development and transformation of Eu-ropean parliamentary-monarchical institutions in the context of the development of political systems of liberal democracy. The objectives of the research are: analysis of the transformations of parliamentary-monarchical institutions, clarification of the institutional parameters of modern European monarchical parliamentarism, identification of crisis trends in the development of parliamentary monarchies in European countries, identification of prospects for their development in the conditions of postmodern and globalization processes. Methodology. To solve the purpose and objectives of the study, historical, comparative methods, functional analysis were used. Results. In the 21st century, the legitimacy of parliamentary monarchies in European states began to be de-termined by a number of new trends in the political process, primarily depending on the ability of specific representatives of ruling dynasties to respond to modern challenges to the institutions of succession. Conclusions. Despite the crisis trends of the post-industrial era, the institution of monarchical rule is quite ef-fectively combined with political and economic freedoms, being included in the system of separation of powers, acting as an integral element of the rule of law, which is why the parliamentary monarchy in the medium term will retain the importance of an important institutional component of modern democratic systems.
Forest Management Reform in the Russian Empire in the Mid – Nineteenth Century: The First Steps of the Reform (on the Example of the Kursk Province)
Authors:   Southwest State University, Nikiforov Sergey A.
Published: January 2023

Relevance. Serious transformations have been carried out in the forest law of Russia in recent decades. The State is currently testing a new concept of forest management and use of forest resources based on the priority of public law. In the history of Russia, there is an experience of evolutionary transformation of the concepts of private and public law in the field of forest legal relations. The Purpose – study the experience of the evolutionary transformation of private and public law in the field of forest management in Russia in the middle of the XIX century. Objectives. Within the framework of the article, the following tasks are solved: analysis of the legal foundations of forest management reform in the middle of the XIX century, features of the implementation of certain provisions at the first stage of the reform on the example of the Kursk province. The methodology of the research is based on the use of a dialectical approach, involving modern methods and methods of studying normative legal acts. Results. Despite the absence of any fundamental legislative act marking the beginning of the reform in the field of forest management in the European part of Russia in the middle of the XIX century, the reform was of a fundamental nature. The provisions of public law were extended to the sphere in which the norms of private law had previously dominated. Conclusion. By the middle of the XIX century, the state had good reasons to streamline and strictly regulate the use of forests, including those that were privately owned. In privately owned forests by the 50s of the XIX century, the problem of forest destruction in the European part of Russia became obvious. The state began the reform with the unprivileged estate – the peasantry. However, the reform was misunderstood not only by peasants, but also by government officials responsible for its implementation. The negative attitude of the officials of the Forestry Department of the Kursk Chamber of State Property to the transformation of the forestry management of the province led to a delay in the reform.

Published: January 2023

Relevance. The development of social networks makes it possible to transform established approaches to the conduct of entrepreneurial activity and to form new scientific and practical approaches to its legal regulation. At the same time, relations arising in social networks and requiring legislative regulation remain within the framework of self-regulation, which negatively affects their stability. To date, the legal status of subjects of law of social networks remains uncertain, especially with the emergence of "state social networks". Relevance of resolving issues related to legal status is predetermined by the specific functioning of social networks, registration of subjects in them, the problem of identification and the order of realization of rights and obligations. The article is a continuation of the author's research on atypical forms of legal relations that require legislative registration. The purpose of the article is to form a scientific approach to the definition of the legal status of the subjects of social networks. Objectives: to identify the range of subjects of law of social networks; to establish the grounds for the emergence of the legal status of the subject of social networking; to substantiate the content of the legal status of the subject of law of social networks. Methodology. The basis of methodology of the conducted research are the achievements of the general theory of law, private and public law science, allowing to systematize the available theoretical and empirical data on the legal status of the subjects of law of social networks, to build an appropriate concept. The results. In the course of the study, the special legal personality of the subjects of the law of social networks is substantiated. Conclusion. The subject composition of the law of social networks is complex. Identification of subjects in a social network is difficult, which endangers the proper protection of the rights and legitimate interests of others. The authors justify the need for independent legislative regulation of relations arising in social networks.

Authors:   Southwest State University, Kaymakova Elena V. , Кorotkih Olga A. , Surkov Alexander N.
Published: January 2023

Relevance. The current family legislation connects the emergence of civil law consequences for participants in family relations with the need to receive legally significant messages from them in cases directly provided for in the law. At the same time, the institution of legally significant messages did not find its consolidation and concretization in the current Family Code of the Russian Federation and applies to family relations according to the rules of civil law, which, in turn, gives rise to practical problems when resolving family disputes in court. The purpose of the study is to identify the features of the intersectoral interaction of the institute of legally sig-nificant messages, including issues of its effective application in the family legal field. The objectives of the study are to determine the legal nature and specifics of legally significant messages in family legal relations, as well as to develop proposals for improving the current family legislation on the use of this institute by subjects of family law. Methodology. Methodology. When solving research problems, both general scientific (analysis, synthesis, generalization, comparison, etc.) and private scientific (formal-dogmatic, intersectoral) methods were used. Results. Inter-sectoral interaction of the institute of legally significant communications in civil and family law has been established; its specific features in family relations related to the action of the imperative method of legal regulation of family relations, as well as the public-legal nature of certain types of legally significant communications, were revealed. Conclusion. Legally relevant messages play an important role not only in civil but also in family law. The ad-dressees of legally significant messages in family law are not only individuals participating in family legal relations, but also state bodies and organizations empowered to protect the rights of minors, which makes it possible to distinguish a new type of legally significant messages in family law - publicly significant legal messages.

Authors:   Southwest State University, Novruzova Oxana B.
Published: January 2023

Relevance. Under the conditions of global changes in the world economy and geopolitical situation, sufficient supply of domestic power market needs guarantees national security of the Russian Federation. High quality of legal regulation of contractual structures is one of the fundamental factors that contribute to the sustainable development of the power market. At the same time, neither the legislator, nor law enforcers, nor representatives of civil science have not developed a unified classification of elements of the system of civil law contracts that contribute to the supply of customers (consumers) with electricity, which makes it timely and expedient to study this issue in a comprehensive way. Purpose. The study is to develop a classification of civil contracts that contribute to the supply of electricity cus-tomers (consumers) as elements of a unified system. Objectives to study the currently developed classifications of contracts in the retail and wholesale electricity market, to identify the specific features of the legislative approach to the system of civil law related to electricity. Methodology of the study is represented by the dialectical-materialistic method, the systematic method, as well as the analysis, synthesis and formal-legal method were applied. Results. Developed the author's version of the system of civil contracts contributing to the supply of buyers (consumers) of electricity: contracts regulating the wholesale electricity market; contracts regulating the retail electricity markets; service contracts that ensure the functioning of the above-mentioned contracts; organizational contracts that contribute to the production, delivery and consumption of electricity. Conclusion. General provisions of the Civil Code of the Russian Federation on contracts and obligations, their performance and responsibility are fully valid for contractual forms serving wholesale and retail power markets of our country, but taking into account principles, norms and rules of energy legislation. It is proposed to introduce into the energy legislation a provision that power supply contracts on the wholesale and retail power markets are possible only with participation of commercial organizations or individual entrepreneurs within the framework of civil law supply contract.

Authors:   Saratov State Law Academy, Lopashenko Natalia A.
Published: January 2023

The relevance of the study is due to the need for constant monitoring of the criminogenic risks of migration processes, including those associated with illegal migration, a phenomenon difficult for criminological assessment that poses a threat to national security. Purpose: rethinking the risks of criminogenicity of migration processes to improve measures to counter national and transnational crime. Objectives: to obtain objective data on the structure of migration crime; to identify trends in its development in order to meaningfully fill the scale of risks of migration processes; generalization of the results obtained. The research methodology is based on a dialectical approach, also includes sociological, statistical, expert assessment method, analysis, synthesis, mathematical, comparative methods. The results. Based on the analysis of up-to-date official statistics and comparison of the results with previously obtained data, as well as expert assessments, the objectivity of which is due to the high latency of migration crime, the criminogenic migration risks corresponding to the average risk indicators have been adjusted. The results obtained are structured depending on the status of migrants and the prevalence of acts committed by them or in relation to them and are summarized in the scale of criminogenicity risks of migration processes (migration) (from minimal to ultra-high). Conclusions. Based on the results of the study, particular conclusions were made about the appropriateness of adjusting the accounting system for crimes committed by foreign citizens and stateless persons and in relation to them, and rethinking the criminological approach to determining migration crime that does not include a group of acts directly related to illegal migration (articles 322.1, 322.2, 322.3 of the Criminal Code The Russian Federation), as well as the general conclusion about the need for constant monitoring of the criminogenic risks of migration (especially its uncontrolled part) in order to coordinate migration policy and counteract various types of crime, which is of great par-ticular importance in the unstable migration situation during crises.
The Concept of Cybercrime in the Russian Federation and the Republic of Kazakhstan
Authors:   Omsk Academy of the Ministry of Internal Affairs of Russia, Karabekov Kanatbek O.
Published: January 2023

Relevance. The article is devoted to one of the current topical issues - the concept of cybercrime in the Russian Federation and the Republic of Kazakhstan. The concept of cybercrime is widely used in criminology and practical activities of the police of the two countries. However, an accurate and complete understanding of cybercrime, as well as its legislative consolidation, remains open to this day. The essence of this problem lies in the fact that the effectiveness of law enforcement agencies in preventing such crimes depends on the correct understanding of cybercrime. Currently, during the rapid development of information technology, the number of crimes committed in cyberspace is growing in proportion to the number of users of computer networks. The purpose is to give an accurate and complete definition of the concept of cybercrime in the Russian Federation and the Republic of Kazakhstan. Objectives: based on the available definitions in the legal literature, to identify the main signs of cybercrime and to systematize the concept of "cybercrime". Methodology. In the process of working on the study, methods of theoretical research (analysis and synthesis, induction and deduction, mental modeling), a comparative legal approach were used. Results. The study suggests an understanding of cybercrime as a historically volatile, latent, social and criminal-legal negative phenomenon, which is a system of crimes committed virtually in the information space using information and communication technologies. Conclusions. The study concluded that the analysis of doctrinal approaches does not show a consensus among scientists in the definition of cybercrime. This is due to different interpretations of cyberspace and ways of using computer systems when committing illegal actions. Despite the differences, scientists raise the question of the relationship between international legislation and Russian legislation, regarding the list of illegal actions that are attributed to crimes committed in the cybersphere. In our opinion, the concept of "cybercrime" can be applied to crimes that are committed using any means of in-formation and communication technologies. Cybercrime is a broader concept than "Internet crime", as it includes the possibility of committing crimes using any information or telecommunications networks.

Authors:   Permanent Mission of the Republic of Mari El to the President of Russian Federation, Kamenskiу Maksim A.
Published: January 2023

Relevance. The right of a citizen to an image as a personal non-property right is subject to absolute protection in accordance with Art. 152.1 of the Civil Code of the Russian Federation. In doctrine and in legal practice, there is no unity of opinion on the civil protection of the right to its image, including the legality of its use and promulgation by other persons, as well as the interpretation of the provisions of the relevant rule and the terminology available in it. In this regard, the work considers gaps in current legislation based on the scientific views of civil law experts and established judicial practice. The purpose of the study is to supplement the theoretical provisions and legislative proposals aimed at deepening scientific knowledge about the protection of the right to the image of a citizen and the uniform application of Art. 152.1 of the Civil Code of the Russian Federation. Objectives: to analyze the scientific positions available in the theory of civil law and Russian judicial practice in cases on the protection of the right to portray a citizen; Identify and clarify existing legal gaps that impede its proper protection; update the previously formulated proposals of civilists to amend Art. 152.1 of the Civil Code of the Russian Federation. Methodology. The study was conducted using methods of induction and deduction, analysis and synthesis, formal-legal, system-analytical and logical methods. The results of the study are formulated proposals for solving theoretical problems related to the application of Art. 152.1 of the Civil Code of the Russian Federation, and improving the current norm on the protection of human rights to the image in order to uniformly enforce it. Conclusion. The study allows us to assert that the rule on the protection of the right to an image of a citizen requires refinement in terms of terminology, including the development of the definition of the image, the appearance of a person, the main object of use, places open for free visits, the form of expression of consent to the publication of one's image, and the elimination of other gaps requiring the attention of the legislator.

The article examines the main stages of the transformation of the legal model for initiating criminal cases on tax crimes, analyzes the changes introduced by Federal Law No. 51-FZ of 09.03.2022, returning a special “tax” reason to Article 140 of the Code of Criminal Procedure of the Russian Federation and adjusting the procedure for considering reports about the crime of the group in question. The problematic issues in the field of interaction between the preliminary investigation bodies and tax authorities in the course of identifying tax crimes and collecting the necessary evidence of the taxpayer's guilt are summarized. The purpose of this study is to study topical issues of improving the procedural form of receiving and verifying reports of crimes in the context of traditional approaches to tax administration. Objectives: analysis of the updated norms of tax and criminal procedural legislation, conceptual theoretical provisions that reflect the existing problems and contradictions in the legal regulation of the "tax" reason, its use in criminal procedural proof at the initial stage of the criminal process; development of proposals for optimization of criminal procedure legislation. Methodology. When writing the article, the method of legal modeling, as well as logical, statistical, historical, comparative legal and other methods were used. Results. The results of the study demonstrate the problems of legal regulation of the new procedure for initiating a criminal case on a tax crime and made it possible to formulate proposals for its improvement. Conclusion. Based on the results of the study, the author states a change in the legal model for initiating criminal prosecution of unscrupulous taxpayers, when the effectiveness of solving crimes is replaced by a risk-based approach in the field of detecting tax crimes. It demonstrates the lack of common views in the assessments of such innovations, taking into account the existing experience of applying such a procedure in 2011-2014, a contradictory understanding of the role of tax audit materials in shaping the reason and grounds for initiating a crimi

Published: January 2023

Relevance. The article considers the problems of the subject of evidence in cases of protecting the privacy of a citizen in accordance with Art. 152.2 of the Civil Code of the Russian Federation. The jurisprudence shows the short-comings in the resolution of this category of cases related to the process of evidence, and in connection with this con-tradictory decisions and the formation of non-uniform judicial practice. In this regard, the study of the means of proce-dural protection of the right to protect human privacy becomes relevant. The purpose of the study is to supplement the theoretical provisions aimed at deepening scientific knowledge about the protection of the right to privacy of a citizen, the subject of evidence in this category of cases for uniform application of Art. 152.2 of the Civil Code of the Russian Federation. Objectives: analyze the judicial practice in cases on the protection of the right to privacy of a citizen with the identification of the actual subject of evidence, scientific positions on this problem; Clarify the existing legal gaps pre-venting the proper protection of this right; update the previously formulated proposals regarding the subject of evidence in cases of this category. Methodology. The study was conducted using methods of analysis and synthesis, induction and deduction, description, formal-legal, system-analytical and system-structural methods, as well as the method of analysis and generalization of judicial practice. The results of the study were formulated proposals for solving theoretical and practical problems related to the peculiarities of the subject of evidence in cases of protecting the privacy of a citizen to improve the quality and achieve uniformity of decisions when considering claims for his protection. Conclusion. The rule on the protection of the right to privacy of a citizen requires clarification in terms of termi-nology and the elimination of other gaps that require the attention of the legislator. To overcome the contradictory interpretation of the meaning of the article itself and the non-unity of judicial practice, it is necessary to explain the Supreme Court of the Russian Federation in the terminology of Art. 152.2 of the Civil Code of the Russian Federation and the mechanism for forming the subject of evidence.

The results of experimental studies on the synthesis by molecular-beam epitaxy of AlGaAs nanowires with InGaAs quantum dots are presented. It was shown that, as in the case of the InP/InAsP material system, the formation of predominantly two objects is observed in the body of AlGaAs nanowire: InGaAs quantum dot due to axial growth and InGaAs quantum well due to radial growth. It is important to note that the grown nanostructures were formed predominantly in the wurtzite crystallographic phase. The results of the grown nanostructures physical properties studies indicate that they are promising for moving single-photon sources to the long-wavelength region. The proposed technology opens up new possibilities for integration direct-gap III-V materials with a silicon platform for various applications in photonics and quantum communications. Keywords: semiconductors, nanowires, quantum dots, III-V compounds, silicon, molecular-beam epitaxy.

The effect of optical radiation in the visible and near-infrared bands on resistive switching of a MOS stack based on ZrO2(Y) film on an n-Si(001) substrate with self-assembled Ge nanoislands on its surface has been studied. An increase in the resistive switching logical gap was observed upon the photoexcitation, in particular, when the photon energies were smaller than the Si band gap. The effect was associated with the impact of the photo-emf at the Si/Ge/ZrO2(Y) interface. In the latter case, the effect is associated with spatially indirect interband optical transitions in Ge nanoislands. Keywords:: memristor, photo-induced resistive switching, yttria-stabilized zirconia, MIS-structure, Ge/Si nanoislands.

Published: January 2023

The results of studying the photoluminescence of nanoheterostructures with multiple Ge1-x-ySixSny/Si quantum wells grown by molecular beam epitaxy on silicon substrates and annealed at different temperatures are presented. As a result of the annealing of the structures, a multifold increase in the intensity of the luminescence peak close in energy to the optical transitions within the multiple quantum wells is observed. The optimal annealing temperature and duration are determined in terms of the intensity of photoluminescence. The luminescent properties of a series of annealed Ge0.93-xSixSn0.07/Si structures with different Ge compositions are investigated. As a result, a shift of the low-temperature photoluminescence peak towards lower energies with an increase in the fraction of germanium in the alloy composition is shown. Thus, the possibility of controlling the luminescence spectrum of Ge0.93-xSixSn0.07/Si nanoheterostructures in the wavelength range of 1.3-2.0 μm is demonstrated. Keywords: nanoheterostructures, photoluminescence, molecular beam epitaxy, infrared emitters.

The degree of polarization of Raman scattering of light in silicon nanocrystals
Authors: Igo A.V.
Published: January 2023

Raman scattering of light (RS) on an array of oriented silicon nanocrystals was studied experimentally. The angular dependence of the intensity of the polarized components of the RS was measured and the parameter of the degree of polarization of scattered light was determined. It was found that the degree of polarization of the RS is related to the size of the nanocrystals in the samples. An array of nanocrystals with the same crystallographic orientation was obtained by thermal annealing of a silicon single crystal damaged by ion implantation. During thermal annealing of the sample, the crystallinity of the layer is restored not simultaneously in the entire damaged volume, but in the form of nanocrystals separated by amorphous area. All the clusters formed have the same crystallographic orientation of the original single crystal. The features of the degree of polarization of the RS in nanocrystals are associated with the quantum-mechanical uncertainty of the phonon wave vector and the uncertainty of the phonon direction in a limited volume of the nanocrystal. The relations linking the degree of polarization of the RS with the size of nanocrystals are obtained. A technique for determining the size of nanocrystals by measuring the degree of polarization of the RS is discussed. Keywords: Raman scattering of light, silicon, nanocrystals, ion implantation, annealing, amorphous phase.

The results of the calculated and experimental depen-dence of the photoluminescence intensity on the excitation power density for silicon-doped GaN layers grown by molecular beam epitaxy are presented. A model was constructed for transitions in a compensated semiconductor upon interband generation of electron-hole pairs. It is shown that the dependence of the photoluminescence intensity on the excitation power density can be used to determine the recombination mechanism and concentrations of donors and acceptors in semiconductor.

The structural, electronic, optical and thermal properties of chalcopyrite LiAlTe2 are studied using the full potential linearized augmented plane wave (FP-LAPW) method framed within density functional theory (DFT). The Wu-Cohen generalized gradient approximation (WC-GGA) was used as exchange-correlation potential to calculate the structural properties. Furthermore, the Tran and Blaha modified Becke-Johnson (mBJ) functional was also employed to compute the electronic and optical properties in order to get best values. The structural parameters at equilibrium are in good agreement with previous experimental and theoretical calculations. The band structures and density of states are calculated and it is found that LiAlTe2 compound is a direct band gap (-) semiconductor. In addition, the optical properties such as dielectric function, refractive index, reflectivity and absorption coefficient are calculated for photon energies up to 25 eV. This study on the optical properties has also been enriched by the introduction of the analysis of birefringence and anisotropy for this material. The calculated values of all parameters are compared with the available theoretical data where a reasonable agreement has been obtained. The study of the material properties at high temperatures and pressures is very important to understand the behavior of a material in severe conditions, so the temperature and pressure dependencies of unit cell volume, bulk modulus, Debye temperature and specific heat capacities are obtained at different temperatures (0-1000 K) and pressures (0-8 GPa) using the quasi-harmonic Debye model. To our knowledge this is the first theoretical prediction of the thermal properties for LiAlTe2 compound and still awaits experimental confirmations. We have included the spin-orbit interaction (SOI) in our calculations which is known to have significant influence on the electronic and optical properties when heavy elements are present. A weak effect is observed for the studied compound. Keywords: DFT, Wien2k, Chalcopyrite, band gap, dielectric function, thermal properties.
Photon echo in germanium with shallow donors
Authors: Tsyplenkov V.V.  , Shastin V.N.
Published: January 2023

A theoretical study was made of the conditions for observing the photon echo effect in a germanium crystal doped with shallow donors. A numerical calculation of the medium polarization excited by a sequence of two optical pulses at a frequency close to the impurity transition frequency has been made. The effect of excitation pulse parameters, such as the pulse duration, the inhomogeneous broadening of impurity transitions and the relaxation rate of population and coherence in the system on the echo is considered. The key aspect in the experimental implementation of the effect is the control of the crystal temperature under photoexcitation, since the rate of coherence relaxation in the system strongly depends on the temperature of the crystal lattice. Keywords: germanium, shallow donors, coherent effects, photon echo.
Viscous flow of two-component electron fluid in magnetic field
Authors: Alekseev P. S.
Published: January 2023

In pure conductors with a low density of defects, frequent electron-electron collisions can lead to the formation of a viscous fluid consisting of conduction electrons. In this work, is studied magnetotransport in a viscous fluid consisting of two types of electrons, for which some of their parameters are different. The difference between such system and the one-component electron fluid is as follows. The scattering of electrons with their transitions from one component to another can lead to an imbalance in flows and concentrations, which affects the flow as a whole. In this work, the balance transport equations for such a system are constructed and solved for the case of a long sample with rough edges. The equation for the flow of the unbalance value towards the edges contains the bulk viscosity term. It is shown that in sufficiently wide samples, the transformation of particles into each other during scattering leads to the formation of a single viscous fluid flowing as a whole, while in narrow samples the two components flow as two independent fluids. The width of the sample at which this transition occurs is determined by the internal parameters of the fluid and the magnitude of magnetic field. The distributions of the flow of the fluid components over a sample cross section and the magnetoresistance of a sample are calculated. The latter turns out to be positive and saturating, corresponding to the transition with increasing of magnetic field from independent Poiseuille flows of the two components to the Poiseuille flow of a uniform fluid.
