Legal issues on membership of the Republic of Azerbaijan in the International Criminal Court
Authors: Eyyubova M.
Published: December 2021

Goal – investigate legal issues on membership of the Republic of Azerbaijan in the International Criminal Court. Methods of research: analysis and study of legal documents containing provisions on the entry of states into the International Criminal Court. By acceding to the Rome Statute, the membership of the Republic of Azerbaijan in the International Criminal Court is always necessary as a state guided by the principles and norms of international law. It is true that for a long time there has been no unequivocal opinion on this issue in society, in scientific circles, as well as in government agencies, mainly due to the jurisdiction of the International Criminal Court. The court’s jurisdiction applies only to individuals, including those who have no jurisdiction over any crime committed before the entry into force of the Rome Statute, and therefore can only consider criminal acts alleged to have been committed after 1 July 2002.

Despite all these negative circumstances, the Rome Statute of the International Criminal Court expands the amendments to the national legislation of the participating States, but does not oblige the State Party to adopt national legislation in accordance with the provisions of the Rome Statute. Although the Republic of Azerbaijan did not accede to the Rome Statute, it benefited from the provisions of this document on war crimes. In general, the fact that the Special Part of the Criminal Code of the Republic of Azerbaijan begins with the norms of international crimes is an indication of the great importance of the Republic of Azerbaijan to the norms of international humanitarian law. At the same time, this step demonstrates the commitment of the Republic of Azerbaijan to global values and international obligations. Discussion: offering a comprehensive and detailed study and use of this practice in academia.
Formation of Ukrainian identity and national state formation in the modern era of the XIX century
Authors: Klymonchuk V. , Ardeli O.
Published: December 2021

The article examines the dynamics and features of the revival of Ukrainian national traditions, mainly languages and their institutionalization, which are accompanied by the formation of an intellectual national-patriotic elite, whose representatives were examples of moral behavior and political leadership in the struggle for national liberation. It is noted that having formed relatively separately in the four main parts of the Ukrainian lands (Dnieper, Galicia, Bukovina and Transcarpathia), the Ukrainian scientific, cultural, educational and political elite began to unite efforts in organizing joint Ukrainian national revival institutions and actively participated in political life. It is argued that Ukrainian nation-genesis does not represent in political history a perfectly uniform movement towards progress. Perhaps this is the contradiction that causes either the decline of national life and the restriction of political freedoms of the masses, or the rapid rise of national and patriotic feelings and the mass awakening of national identity and the struggle for political freedoms. The middle of the XIX century, which became a period of national revival for the peoples of Europe, has been studied. This was preceded by important socio-political events of the seventeenth and eighteenth centuries, in particular the bourgeois-democratic revolutions, which largely implemented the ideas of freedom, equality, and justice. It is outlined that the bourgeois-democratic revolutions and the national liberation struggle of the European peoples gave prospects for the Ukrainian nation to be reborn and developed. However, the Ukrainian lands were part of the imperial states with different levels of development of political culture, law, public morality, education and more. Thus, the Austrian monarchy of “enlightened absolutism” and the Russian monarchical despotism treated the Ukrainian people differently. Political events of the late XIX – early XX centuries. analyzed through the prism of the then dominant imperial spirit and the rise of the national consciousness of the peoples who were colonized by the imperial states. This means that Ukrainian national genesis and its institutionalized political freedoms are understood only in the closest connection with the imperial spirit of the European geopolitical space and national liberation movements. It is proved that the concept of political freedom for the peoples whose territories were seized by the imperial states, arose as a scientific philosophical and political thought in the first half of the XVIII century. and already in the works of J. Locke, J. Vico, N. R. J. Turgot, J. N. Condorcet and I. Kant, G. W. F. Hegel, and many other thinkers, it acquired a general civilizational worldview significance.
On the question about opposition to the information component aggression of the Russian Federation
Authors: Vasylchenko O.
Published: December 2021

Ukrainian law guarantees freedom of speech and expression. This is in line with international and regional instruments (Convention for the Protection of Human Rights and Fundamental Freedoms, International Covenant on Civil and Political Rights, Declaration of Human Rights) to which Ukraine is a party. Unfortunately, Ukraine is no exception, due to the conflict with the Russian Federation. The Revolution of Dignity of 2014 and the subsequent illegal activities of the neighbouring state (annexation of Crimea, occupation of the territories in the South-East of Ukraine) affected the legislative and regulatory framework of Ukraine regarding freedom of speech and freedom of expression. In order to counter aggression, the state has adopted a number of laws aimed at counteracting foreign interference in broadcasting and ensuring Ukraine’s information sovereignty. The implementation of these laws has been criticized for being seen by NGOs as imposing restrictions on freedom of expression and expression. However, censorship and selfcensorship create another serious restriction on freedom of speech and the press. The Law on Transparency of Mass Media Ownership, adopted in 2015, provides for the disclosure of information on the owners of final beneficiaries (controllers), and in their absence – on all owners and members of a broadcasting organization or service provider. In 2019, Ukraine adopted a law on strengthening the role of the Ukrainian language as the state language, which provides for language quotas for the media. According to the Law on Language, only 10% of total film adaptations can be in a language other than Ukrainian. Ukraine has adopted several laws in the field of information management to counter foreign influence and propaganda. According to the report of the Organization for Security and Cooperation in Europe, for the period from January 1, 2017 to February 14, 2018, the State Committee banned 30 books published in the Russian Federation. Thus, for the first time faced with the need to wage an “invisible” war on the information front, Ukraine was forced to take seriously the regulation of the media and the market. By imposing a number of restrictions on a product that can shake sovereignty and increase the authority of the aggressor in the eyes of citizens, the legislator, guided by the needs of society, also contributes to the promotion of Ukrainian (for example, by introducing quotas).
Value-legal aspects of providing legal protection of rights to trademark in Ukraine
Authors: Kotenko M.
Published: December 2021

The paper reveals the relevance of scientific knowledge of the value and legal aspects of understanding the signs for goods and services as a basis for legal support of rights to them. The philosophical and scientific basis of scientific research of value-legal aspects of understanding of signs for goods and services is established. The scientific views of scientists concerning understanding of value and legal aspects of signs for the goods and services are generalized. It is concluded that the current state of scientific development of axiology of understanding of signs for goods and services indicates the episodic nature of these studies, as the scientific study of these issues was carried out indirectly through scientific analysis of other related legal phenomena and processes. The author summarizes the methodological potential of the valuelegal approach to the understanding of signs for goods and services. Based on the analysis of doctrinal approaches to understanding the value and legal aspects of marks for goods and services, the value and legal aspects of legal protection of rights to marks for goods and services in Ukraine are determined. It is concluded that the essence and content of legal protection of trademark rights for goods and services will be determined by the functional purpose of the brands themselves, which in turn will characterize the value of legal protection of trademarks as a whole. The legal protection of trademark rights for goods and services has a guarantee value in relation to the latter in terms of their ability to individualize goods and services through their separation among homogeneous goods and services on the market. It is proved that the legal protection of trademark rights for goods and services allows their public distribution and advertising of goods and services.
The oath of a judge – oath of office and judicial symbol
Authors: Kravchuk O. , Ostashchuk I.
Published: December 2021

The oath of a judge as an oath of office and as an element of judicial symbolism is considered in the article. The oath of a judge belongs to the categories of oaths of office, taken by an official upon taking office. At the same time, it belongs to the judicial oaths used in the justice process and is an element of judicial symbols. The oath of a judge as an oath of office symbolizes the endowment of a judge as an official by the state (judicial) power, the moment of his acquisition of powers (it is the inauguration ceremony), and the duty of a judge as an official to perform his duties properly. The oath of a judge as a judicial symbol represents a public and solemn obligation of the judge to exercise a fair trial in all its manifestations, including: independence and impartiality of the court, adversarial proceedings, equality of arms, and the rule of law. The judge takes the oath in a solemn atmosphere in the presence of senior officials (in Ukraine – in the presence of the President of Ukraine). It is an important ritual – a symbol of giving a person judicial power. The oath itself is a symbolic action of conscious choice of responsible and impartial observance of the law in the professional functions of realization of the rule of law for the good of all people. The coronavirus pandemic has shown that gathering a large number of people in one room can be problematic, so the oath ceremony was held even outdoors. It is stated that holding a ceremony in one of the judicial bodies, for example, in the premises of the Supreme Court or (subject to quarantine restrictions) in the territory of the Supreme Court may symbolize the independence of the judiciary and each judge from other branches of power. The peculiarity of the oath of a judge in Ukraine is its one-time nature. It should be taken only by a person first appointed to the position of a judge. In case of an appointment or transfer to another court, the judge shall not take the oath again. In this aspect, the oath of a judge is similar to the oath of a civil servant, which is taken only by persons recruited for the first time.
European Grouping of Territorial Cooperation as the instrument of cross border cooperation
Authors: Lemko Yu.
Published: December 2021

The article considers one of the most common and most effective forms of cross-border cooperation between the countries of the European Union, namely the European groupings of territorial cooperation. The role of territorial cooperation in the European Union is constantly growing as it is the basis of political, economic and social cohesion, which is an integral part of Ukrainian society. The development of territorial cooperation is due to the change and development of national, regional or local participants in this process. The Schengen Agreement, the common internal market and the common currency, as well as the emergence of numerous new cross-border projects and the development of cross-border territories, are integral parts of this process. The article examines the EGTC Tisza, which was established in October 2015 in the Transcarpathian region of Ukraine together with the Hungarian region of Szabolcs-Szatmár-Bereg and the municipality of Kisvárd. It is noted that the union has received broad social and political support from both sides at the regional and local levels. This event was decisive for both Ukraine and the EU, as for the first time such an association was created with the participation of a non-EU country. This was a long-awaited step, as the participating regions have long been cooperating together in various fields, including the implementation of grant projects. Many issues need to be addressed together, including flood protection, the rehabilitation of wastewater treatment plants, transport and the development of economic ties. We can say that today Euroregions are the most developed form of cross-border cooperation in Ukraine, but their activities also show a range of problems that hinder their effective functioning. This includes a large number of participants with different cultural and economic characteristics, disparities in the legislation and administration of the country, the low level of business structures and non-governmental organizations. Issues such as the lack of a systematic approach to the organization of Euroregional cooperation, the low level of regional government and the lack of financial support are also worth mentioning.
Temporal certainty of material civil legal relations. Some problematic issues
Authors: Guyvan P.
Published: December 2021

This article is devoted to the study of the scientific question of the temporal parameters of the certainty of the protection and legal relationship that arises in the case of violation of the subjective civil rights of the person. The author’s vision of the time of existence of the law is given, in this context the fundamental difference between the concepts of "duration of the legal relationship" and "time of exercise of subjective right" is substantiated. It is substantiated that the duration of the behavior of the contractors is not always equal to the duration of the legal relationship, because the moment of the relationship does not always coincide with the moment of its implementation. Along with the legal relationship arises not the behavior itself, but only the legal means of ensuring such behavior – a subjective right and legal obligation. So, on the other hand, the time for the exercise of a subjective right coincides with the period of its existence. Given that the temporal factors in the protection of law have a significant specificity of regulation, a fundamental separation of protective and regulatory material relations. The fact is that it is not always easy to establish a temporal boundary when an intact right passes to a disturbed state. This means that there are certain problems in accessing the appropriate protective tools. Examples of such substitution of concepts and criteria for their elimination are given. The paper also provides a scientific definition of the real essence of the protective relationship, which is that in the case of violation of subjective substantive law there is a different than before, the interaction, which is protective and legal in nature. It includes the material claim of the right holder to the infringer and the corresponding obligation of the latter. It is noted that the forms of implementation of the protection requirement of the holder of the new right may be different, each of them has its own time regulators. For example, a lawsuit is filed for a limited period of time – a statute of limitations, while for operational measures or other out–of–court claims there are special deadlines, or no time limit at all. Therefore, the need for a separate temporal mediation of each of these methods of protective response is emphasized.
Reflections on the existence of the science of criminal law
Authors: Mytrofanov I.
Published: December 2021

The article states that today the issues of the role (purpose) of criminal law, the structure of criminal law knowledge remain debatable. And at this time, questions arise: whose interests are protected by criminal law, is it able to ensure social justice, including the proportionality of the responsibility of the individual and the state for criminally illegal actions? The purpose of the article is to comprehend the problems of criminal law knowledge about the phenomena that shape the purpose of criminal law as a fair regulator of public relations, aimed primarily at restoring social justice for the victim, suspect (accused), society and the state, the proportionality of punishment and states for criminally illegal acts. The concepts of “crime” and “punishment” are discussed in science. As a result, there is no increase in knowledge, but an increase in its volume due to new definitions of existing criminal law phenomena. It is stated that the science of criminal law has not been able to explain the need for the concept of criminal law, as the role and name of this area is leveled to the framework terminology, which currently contains the categories of crime and punishment. Sometimes it is not even unreasonable to think that criminal law as an independent and meaningful concept does not exist or has not yet appeared. There was a custom to characterize this right as something derived from the main and most important branches of law, the criminal law of the rules of subsidiary and ancillary nature. Scholars do not consider criminal law, for example, as the right to self-defense. Although the right to self-defense is paramount and must first be guaranteed to a person who is almost always left alone with the offender, it is the least represented in law, developed in practice and available to criminal law subjects. Today, for example, there are no clear rules for the necessary protection of property rights or human freedoms. It is concluded that the science of criminal law should develop knowledge that will reveal not only the content of the subject of this branch of law, but will focus it on new properties to determine the illegality of acts and their consequences, exclude the possibility of using its means by legal entities against each other.
Intersectional relations between executive law and civil law of Ukraine
Authors: Sergiienko N.
Published: December 2021

The scientific article is devoted to analyze the intersectional relations between executive law of Ukraine and civil law of Ukraine. The classification of forms of intersectional relations, offered by M.Yu Chelyshev, was taken as the ground of theoretical and methodological base of scientific research the intersectional relations between executive law of Ukraine and civil law of Ukraine. Even though this scientist-lawyer researched the intersectional relations of civil law, grounding on the subject of his scientific researches, his classification is stated as universal and grounded enough and can be used for different legal researches. In the scientific article the intersectional relations between executive law of and civil law of Ukraine are discovered though direction as follows: 1) intersectional interaction between executive law of Ukraine and civil law of Ukraine (it represents by using in executive law definitions and constructions of civil law. As an example of definitions and constructions of civil law, that are used in executive law, can be stated the definition of agreement); 2) intersectional influence between executive law and civil law (it represents by mutual influence of compositions of executive law and civil law, especially norms and institutions. The bright example of that mutual influence is the legal status of some kinds of property on the context of forfeiture the property – some kinds of property are out of forfeiture in the executive process, despite that property are out of turnover restrictions); 4) intersectional legal and collision regulation (it represents by direct and indirect mutual renvois between civil legislation and executive legislation. As an example can be used the direct renvoi to art. 28 of The Civil Code of Ukraine from subpar. 5 par. 2 sec. III of The Instruction of Compulsory Execution Organization, approved by The Ministry of Justice of Ukraine from 02.04.2012 under № 512/5).
Criminalization of drunk driving: problems of legislative practice
Authors: Popov K.
Published: December 2021

The article highlights the Ukrainian experience of criminalization of drunk driving as a result of amendments to criminal and administrative legislation in 2018–2021. The importance of systematization and validity in making changes to administrative and criminal law is noted. Attention is drawn to the need for careful observance of the rules of legal technique in legislative activity, given that the use of administrative and criminal law is associated with the most significant restrictions on human rights and freedoms. It is noted that there are violations of the rules of legal technique, allowed in the relevant laws in terms of the provisions on criminalization and decriminalization of drunk driving: violations of the homogeneity of legal regulation (Law № 720-IX regulated an issue that was not the subject of its regulation); internal consistency (Law № 720-IX on amendments “in connection with the adoption of Law № 2617-VIII” amended the Law itself № 2617-VIII); external consistency (provisions of Law № 720-IX contradict the provisions of Article 2 of the Code of Administrative Offenses and Article 3 of the Criminal Code of Ukraine); linguistic (in paragraph 117 of the Law № 720-IX there is a morphological error); procedural (violated the requirements of Articles 90, 92 of the Regulations). Attention is drawn to the content of the conclusions and the legal significance of the explanations of the Parliamentary Committee on Law Enforcement, adopted on the criminalization of drunk driving. It is noted that the relevant committee violated the regulatory procedures and provisions of the legislation on parliamentary committees. The consequences of the relevant technical and legal violations (legislative uncertainty) are highlighted and ways to eliminate these problems are suggested.
Media image of the Armed Forces of Ukraine as a component of the popularization of the military service among young people
Authors: Yenin M. , Stefanovych A.
Published: December 2021

The article is devoted to the problem of covering news about the Armed Forces of Ukraine in the Ukrainian mass media, which shape the image and prestige of this profession at the national level. Different approaches to defining the concept of “image” and the specifics of building a media image are considered. It is established that the image of the Armed Forces of Ukraine has an impact not only on the civilian population, but also performs an educational and motivating function on servicemen. The main attention to the conceptualization of the concept of “image” is focused on the sociological approach, in particular, a significant role is given to symbolic interactionism. Image, in particular media image as a phenomenon that involves the two-way interaction of the exchange of certain symbolic signs, is studied. This approach helps to determine the role and influence of the media in the process of transmitting information to the audience. The specifics and position of military service in Ukraine are considered, its popularization as one of the elements of military-patriotic education is analyzed. An analysis of the issue of youth readiness to defend Ukraine is presented and what factors may reduce the attractiveness of military service. It was found that information in the media, which forms the image of the Armed Forces of Ukraine, can influence the involvement of young people in the military sphere. Based on the content analysis of the new media segment (Telegram messenger), the main areas in the field of view of journalists that related to the activities of the Armed Forces have been identified. The positive and negative characteristics of the media image of the armed forces have been studied. A number of narratives that can have a positive impact on the promotion of military service among young people have been identified through the use of qualitative paradigm techniques (interviews and focus group discussions).
Norm of criminal law under the draft Criminal code of Ukraine
Authors: Mytrofanov I.
Published: December 2021

The article considers the rule of law, the rule of criminal law. When studying the norm of criminal law, I rely on the fact that it is a mandatory rule of conduct for failure to commit a criminal offense under the criminal law of the Special Part of the Criminal Code of Ukraine, organically related orders, compliance with which is ensured by coercive potential criminal law influence. The norm of criminal law consists of: 1) conditions for the implementation of criminal law (hypothesis); 2) criminal law normative – obligatory legal requirement for non-commission of an act provided by the instruction of the Special Part of the Criminal Code (disposition); 3) sanction for non-compliance with these legal requirements. Mandatory requirements (rules) contained in the articles of the General and Special Parts of the Criminal Code and organically supplement (clarify) the content of the relevant structural part of the criminal law or contain procedural issues for its application and implementation. The article analyzes the hypothetical, dispositional and sanctioning dictates of the draft Criminal Code of Ukraine. It is concluded that the draft Criminal Code of Ukraine does not significantly change the approaches to understanding the rules of criminal law as a system of established (sanctioned) by the Verkhovna Rada of Ukraine and legally secured universally binding criminal law norms and organically related commands. project composition, their rights and responsibilities, tasks of the Criminal Code, legal facts, etc.), compliance with which is ensured by the coercive potential of the means of criminal law influence. The considered norm in a broad sense provides for a three-tier structure and is fixed in the criminal law. At the same time, the structural elements of the norm of criminal law in the «broad» sense are placed in the articles of both the General and Special parts of the draft Criminal Code of Ukraine. Further research should focus on understanding the concept and structure of criminal law, as it will help both the legislator and the court. Proper interpretation of the concept and structure of criminal law encourages parliamentarians to more fully and accurately reproduce in the text of the Criminal Code of Ukraine all the necessary elements of criminal law in view of the purpose of its development and adoption, and the judge, investigating judge (court) – to find, compare and understand these elements, to establish their interrelations and the legal will of the legislator fixed in this norm, and also to provide its reliable realization according to a letter of the law. This knowledge allows members of society to navigate the system of criminal law obligations for their implementation.

Their shortcomings and positive directions are revealed. The socioeconomic and legal preconditions for illegal extraction of precious stones of organogenic formation are indicated.
Concentration of stresses near the hole in contact with rigid cylinder in composite plate, taking into account lateral clearances
Authors: Rudakov Konstantin , Dyfuchyn Yury , Bakhtovarshoiev Tymur
Published: December 2021

Problems. When designing bolted joints (BJ), it is necessary, in particular, to carry out their verification calculations for strength.  At the same time, it is desirable to use express analysis: calculations by simple formulas of sufficient accuracy. For BJ of plates made of layered polymer composite materials (PCM), the problem has not yet been solved.

The aim of the study. The task is to test the accuracy of three known formulas for quick calculation of the value of the stress concentration factor (SCF) in zone of contact of bolt-hole with a rigid cylinder (bolt). The study was carried out on contrasting examples of materials and schemes of reinforcement of plates made of PСM, taking into account possible clearance between bolt and hole in the real range: from zero to 1% of diameter.

Methodology of implementation. Numerical calculations were made using the finite element method (contact problem) for the BJ of plates made of layered PCM. 3D orthotropy of each monolayer was provided. Three simple formulas of express analysis were tested. The results are summarized in the tables and many illustrations are given.

Research results. Numerical estimates of depending of the SCF in zone of the surface of the bolt-hole from considered factors are obtained.  The factors are the material characteristics, the schemes of reinforcement of plates made of layered PСM and the values of the clearance between bolt and hole in the plates, as well as the accuracy of the considered formulas.

Conclusions. Changing the material and the scheme of reinforcement of plate made of layered PСM leads to a significant change in the values ​​of maximum stresses and SCF in zone of the bolt-loaded hole in the weakened by hole cross section of a plate. Considered formulas of the express analysis have insufficient accuracy for consideration of contrast properties of materials and schemes of reinforcement of a plate. Changing size of clearance between bolt and hole in the range from zero to 1% of the diameter leads to relatively small changes in SCF: up to 10% maximum. Additional research is needed.
Influence of the heat transfer coefficient on the level of residual stress after heat treatment of the VVER-1000 reactor baffle
Authors: Makhnenko Oleg , Kandala Stepan , Basistyuk Nazar
Published: December 2021

Background. Improvement of the methodology for the computational analysis of residual stresses in the structural elements of the reactor is an integral part of the work when extending the service life of NPP power units.

Objective. Determine the value of residual technological stress arising in the baffle of a VVER-1000 reactor during welding and postweld heat treatment according to the austenitizing mode. To evaluate the effect of considering the dependence of the heat transfer coefficient on the temperature of the baffle surface at cooling in air during heat treatment.

Methods. Numerical modeling of the stress-strain state of the baffle during welding and postweld heat treatment was carried out using the finite element method.

Results. It was determined that in the process of heat treatment according to the austenitizing mode, the residual welding stress in the baffle are almost completely relaxed. Due to the high temperature gradient during rapid cooling in air after heating in the process of austenitization, new rather high residual stresses are formed in the zones of the baffle with the greatest metal thickness.

Conclusions. Based on the results of the investigation, a high level of residual technological stress was determined, which should be considered when calculating the justification for extending the service life of the VVER-1000 reactor baffle.

Authors: Rudenko Andrii , Zubko Vladyslav , Khvorost Viacheslav , Lysenko Andrii
Published: December 2021

The object of study is a single-stage double-suction axially split volute casing centrifugal pump.

Background. In the design process of pumps, the problems associated with ensuring the tightness of the axial joint of a pump casing being under the effect of mechanical and temperature loads, are being solved. During the study of axial joint tightness, numerical calculation methods are used to estimate the pressure intensity on the contacting surfaces. A detachable joint under the external load satisfies the criterions of the tightness if the pressure intensity on the sealing surfaces is higher than values of the specific pressure prescribed by regulations. However, inability to experimentally determine the pressure intensity on the contacting surfaces has so far prevented to assess the accuracy of results obtained by the numerical calculation methods.

Objective. In order to verify the numerical results obtained by mathematical models, an experiment was carried out using a special Prescale film that registers the magnitude of the contact pressure on the joint of the specimen model of the flange fragment. Based on the experimental results, an analysis of the pressure intensity distribution was conducted.

Methods. To conduct the experiment, there was developed a method for determining the pressure intensity on the contacting surfaces according to the proposed scheme of the specimen of the flange fragment.

Results. A comparative analysis of the solving results obtained for the contact problem on the finite-element models of the flange fragment and the zone of the pump casing joint in the discharge chamber area showed a good coincidence of the results. Analysis of results obtained experimentally on the specimen of flange fragment and results of the numerical calculation on the flange fragment model also showed a good agreement.

Conclusions. Therefore, results of the calculation of the pressure intensity in the detachable joints on mathematical models have been experimentally confirmed.

Technical Vision System for in-Room Access Control
Authors: Fironov Artem Ihorovych , Levchenko Vitaliy Viktorovych
Published: December 2021

Access systems with face recognition is widely used today. They are used in many enterprises and institutes where it is necessary to control the flow of passing people. 
Facially recognizable technical vision systems are important because they can be used to store specific individuals faces and use them for access control. As a result of analysis of same modern systems the variant of system there are additional functions is offered.
The system consists of ESP-EYE module, with build-in wi-fi and Bluetooth modules, chip sensor camera “ OV2640” and LED display, which dasplays a notification for a person about granting or denying access, notifications are in two collors: geen and red respectively.. Also it has an emergency power supply in case of unforeseen situations.
Wi-fi is used as a means of transmiting data from camera to the server. This transmition method of data transmition has several advantages over Bluetooth. It allows to the system to transfer data at a much higher speed and over a grater distance, it is also more secure, provides access to the internet and allows to control the system  remotely. All the listed advantages of this method of transmition give us a great variability in the operation and placement of the system.
To recognize people system use a comparison method. It compares the person’s face with a database and, after processing it produces the result. To optimize and speed up this process, the system uses a method of image compression based on discrete wavelet transform. This method is the transmission of a signal through several filtres, usualy two.
First, the signal is passed through a low-pass filter whis a pulse response g, resulting in an output signal in the form of a convolutional sum. At the same time the signal is decomposed by a high pass filter. The LPF gives an approximate shape of the output signal, and the HPF – the signal of difference or additional detail.
Discrete wavelet transform in an oriented basis makes it possible to construct transformation matrices with a given number of filters ”m”, where “m” is in the general case a prime positive number.
The simplest way to compare the two images is by substracting the brightness values of the two matrices and estimating the resulting matrix of differences using standard deviation. The use of standard deviation in combination with fiberboard in OB allows to speed up the process of face recognition in the system by discarding unncessary details, the absence of which minimaly harms the accuracy of the results.
The advantages of this system are that it is less expensive, in compareson with existing analogs, less energy-consuming, easy to assemble and install, uses a relatively simple and at the same time quite accurate method of identidying a persons identity.
Sugarcane biomass as а potential carrier for drug delivery system
Authors: Halysh Vita , Sevastyanova Olena , Yadong Zhao
Published: December 2021

Non-steroidal anti-inflammatory drugs are well-known medications for reducing pain and a group of drugs that can cause mucosal damage of the stomach. The negative effects on the digestive system can be reduced by immobilization of drugs on various carriers, for instance, on the components of plant biomass, for the creation of drug delivery system. Plant biomass is a lignocellulosic complex consisting of lignin, cellulose and hemicellulose that can potentially be regarded as a carrier of pharmaceuticals. Sugarcane residues such as bagasse and straw are biomass by-products of the sugarcane industry. One of the prospective ways for their efficient utilization can include chemical processing with the aim of obtaining effective biosorbents or so-called carriers of different composition and structure. The aim of the work was to study the structural, morphological, and sorption properties of cellulose, lignin, and lignocellulose, derived from sugarcane biomass (bagasse and straw) by means of delignification and hydrolysis, as potential components for drug delivery system. Sugarcane straw samples show higher densities in comparison with bagasse samples. Both lignin samples from bagasse and straw have greater bulk and true density if compared to other materials from sugarcane biomass of cellulosic and lignocellulosic nature. The increase in adsorption pore volume in lignins is observed, being indicative of better sorption ability. Both samples of cellulose and lignocellulose from straw have greater pore structure if compared to the initial material. The values of sodium diclofenac sorption efficiency correlate with the values of pore volume for corresponding materials. Lignin from sugarcane straw, which shows greater porosity, has greater sorption properties. SEM images show that the initial materials and treated materials have complex morphology. FTIR spectra show a clear difference in the structure of lignocellulose, cellulose, and lignin from sugarcane bagasse and straw. The potential application of biopolymers from bagasse and straw as organic carriers of sodium diclofenac was studied. With this purpose, plant polymers were impregnated with an alcoholic solution of sodium diclofenac and the desorption process was investigated. The lignin sample from sugarcane straw has a longer period of drug release, which indicates the obtained effect of prolongation.

There are unsolved problems related to inflation, gravity, dark matter, dark energy, missing antimatter, and the birth of the universe. Some of them can be better answered by assuming the existence of aether and hypoatoms. Both were created during the inflation in the very early universe. While aether forms vacuum, hypoatoms, composed of both matter and antimatter and believed to be neutrinos, form all observable matter. In vacuum, aether exists between the particle-antiparticle dark matter form and the dark energy form in a dynamic equilibrium: A + A-bar = gamma + gamma. The same reaction stabilizes hypoatoms and generates a 3-dimensional sink flow of aether that causes gravity. Based on the hypoatom structure, the singularity does not exist inside a black hole; the core of the black hole is a hypoatom star or neutrino star. By gaining enough mass, ca. 3 X 1022 Msun, to exceed neutrino degeneracy pressure, the black hole collapses or annihilates into the singularity, thus turning itself into a white hole or a Big Bang. The universe is anisotropic and nonhomogeneous. Its center, or where the Big Bang happened, is at about 0.671 times the radius of the observable universe at the Galactic coordinates (l, b) ~ (286°, -42°). If we look from the Earth to the center of the universe, the universe is rotating clockwise.
Galaxy Formation, Evolution and Rotation as a 4D Relativistic Cloud-World Embedded in a 4D Conformal Bulk: From String to Cloud Theory

The recent observation of the G2 gas cloud orbit around the galactic centre has challenged the model of a mere supermassive black hole that should have destroyed it. In addition, the Planck Legacy 2018 (PL18) release has preferred a positively curved early Universe with a confidence level exceeding 99%. In this study, the formation of a galaxy from the collapse of a supermassive gas cloud in the early Universe is modelled based on extended field equations as a 4D relativistic cloud-world that flows and spins through a 4D conformal bulk of an initial positive curvature considering the preference of the PL18 release. Owning to the curved background, this scenario of galaxy formation reveals that the core of the galaxy undergoes a forced vortex formation with a central event horizon leading to opposite vortices (traversable wormholes) that are spatially shrinking through evolving in the conformal time. It indicates that the galaxy and its core are formed at the same process where the surrounding gas clouds form the spiral arms due to the frame-dragging induced by the fast-rotating core. Further, the bulk conformal curvature evolution demonstrates the fast orbital speed of outer stars owing to external fields exerted on galaxies as they travel through conformally curved space-time. Accordingly, the G2 gas cloud that only faced the drag effects could be explained if its orbit is around the vortex but at a distance from the central event horizon. These findings could explain the fast orbital speed of outer stars where the galaxy formation and its core simultaneously could explain the formation of the supermassive compact galaxy cores with a mass of ~109 M⊙ at just 6% of the current Universe age and thus could resolve the black hole hierarchy problem.

Transcription factors (TFs) are proteins that recognize specific DNA fragments in order to decode the genome and ensure its optimal functioning. TFs work at the local and global scales by specifying cell type, cell growth and death, cell migration, organization and timely tasks. We investigate the structure of DNA-binding motifs with the theory of finitely generated groups. The DNA ‘word’ in the binding domain -the motif- may be seen as the generator of a finitely generated group Fdna on four letters, the bases A, T, G and C. It is shown that, most of the time, the DNA-binding motifs have subgroup structure close to free groups of rank three or less, a property that we call ‘syntactical freedom’. Such a property is associated to the aperiodicity of the motif when it is seen as a substitution sequence. Examples are provided for the major families of TFs such as leucine zipper factors, zinc finger factors, homeo-domain factors, etc. We also discuss the exceptions to the existence of such a DNA syntactical rule and their functional role. This includes the TATA box in the promoter region of some genes, the single nucleotide markers (SNP) and the motifs of some genes of ubiquitous role in transcription and regulation.

The Social Economy (SE) emerges as an interesting alternative to deal with social problems that often cannot be met by the services provided by the State. However, one of the concerns relates to the ability of these institutions to meet the demands of stakeholders concerning accountability. In this sense, the present work aimed to determine if the IPSS are prepared to meet the management requirements by increasing their accountability. For that purpose, we conducted qualitative research, with an exploratory focus, with 31 Portuguese Private Social Solidarity Institutions (IPSS). The interviews took place between June and July 2019, with those responsible for managing the entities. The interviews were guided on a semi-structured script based on the literature review. After Content Analysis, it was found that, in most of the institutions interviewed, the board does not use management tools, such as performance analysis, social impact assessment, strategic planning and quality management systems, even recognising the importance of using them. The fact is due to the lack of access or knowledge about its use. In addition, the majority of the IPSS interviewed showed concern about the transparency and ethics of managers. Current strategic management practices are remarkably targeted at companies in the for-profit sector and can compromise the principle of investments in human and social issues. Thus, the introduction of new activities can further reinforce the pressure felt by these institutions in carrying out operational activities.
