Shear viscosity in microscopic calculations of A+A collisions at energies of Nuclotron-based Ion Collider fAcility (NICA)

Time evolution of shear viscosity $\eta$, entropy density $s$, and their ratio $\eta / s$ in the central area of central gold-gold collisions at NICA energy range is studied within the UrQMD transport model. The extracted values of energy density, net baryon density and net strangeness density are used as input to (i) statistical model of ideal hadron gas to define temperature, baryo-chemical potential and strangeness chemical potential, and to (ii) UrQMD box with periodic boundary conditions to study the relaxation process of highly excited matter. During the relaxation stage, the shear viscosity is determined in the framework of Green-Kubo approach. The procedure is performed for each of 20 time slices, corresponding to conditions in the central area of the fireball at times from 1~fm/$c$ to 20~fm/$c$. For all tested energies the ratio $\eta / s$ reaches minimum, $\left( \eta/s \right)_{min} \approx 0.3$ at $t \approx 5$~fm/$c$. Then it increases up to the late stages of the system evolution. This rise is accompanied by the drop of both, temperature and strangeness chemical potential, and increase of baryo-chemical potential.Comment: LATEX, 9 pages, 10 figure

Special aspects of the administrative and legal status of refugees and internally displaced persons

Панова, О. О. Особливості адміністративно-правового статусу біженців і вимушених переселенців / Панова Оксана Олександрівна // Юридичний бюлетень. – 2021. – Вип. 20. – С. 71-77. – DOI: https://doi.org/10.32850/LB2414-4207.2021.20.10У статті досліджено особливості адміністративно-правового статусу біженців і вимушених переселенців. Проаналізовано підходи учених-правознавців до розуміння сутності категорії «правовий статус». Установлено, що в більшості випадків сутність правового статусу суб’єкта відповідних суспільних відносин розкривається через перелік його змістових складників, до яких, як правило, віднесено права й обов’язки особи. Обґрунтовано, що такі підходи є доволі вузькими, оскільки поза увагою залишають низку складників правового статусу будь-якої особи. Здійснено аналіз більш широких підходів до розуміння сутності правового статусу особи, завдяки чому з них викреслено зайві для правового статусу біженців і вимушених переселенців змістовні складники. Установлено, що адміністративно-правовий статус біженців і вимушених переселенців об’єктивізовано в нормах адміністративного права. Визначено, що необхідною умовою набуття особою адміністративно-правового статусу біженця або вимушеного переселенця є наявність у неї правосуб’єктності, що розглядається як структурний складник такого статусу. Обґрунтовано, що одним із основних структурних складників адміністративно-правового статусу біженців і вимушених переселенців є їхні права й обов’язки. З’ясовано, що окремим структурним складником адміністративно-правового статусу біженців і вимушених переселенців є міра їх юридичної відповідальності. Визначено, що особливості адміністративно-правового статусу біженців і вимушених переселенців будуть знаходити свій прояв у межах особливостей реалізації окремих із його структурних складників. За допомогою аналізу чинного національного законодавства, на підставі якого здійснюється нормативно-правова регламентація адміністративно-правового статусу біженців і вимушених переселенців, визначено особливості реалізації окремих із його структурних елементів. Надано авторське бачення сутності адміністративно-правового статусу біженців і вимушених переселенців.The features of the administrative and legal status of refugees and internally displaced persons have been examined in the article. The approaches of legal scholars regarding the understanding of the essence of the category of “legal status” have been analyzed. It has been established that in most cases the essence of the legal status of the subject of the rel- evant social relations is revealed through the list of its substantive components, which, as a rule, include the rights and obligations of a person. It has been substantiated that such approaches are rather narrow, since they ignore a number of components of the legal status of any person. The analysis of broader approaches to understanding the essence of the legal status of an individual has been carried out, due to which the content components, that are irrelevant for the legal status of refugees and forced migrants, have been deleted from them. It has been established that the administrative and legal status of refugees and internally dis- placed persons is objectified in the norms of administrative law. It has been determined that a necessary condition for a person to acquire the administrative and legal status of a refugee or forced migrant is that he or she has quality of being a person in contemplation of the law, which is considered as a structural component of such a status. It has been substantiated that one of the main structural components of the administrative and legal status of refugees and internally displaced persons is their rights and obligations. It has been established that the degree of refugees’ and forced migrants’ legal responsibility is a separate structural com- ponent of their administrative and legal status. It has been determined that the peculiarities of the administrative and legal status of refugees and internally displaced persons will be manifested within the peculiarities of the implementation of its individual structural com- ponents. By analyzing the current national legislation, on the basis of which the legal reg- ulation of the administrative and legal status of refugees and internally displaced persons is carried out, the peculiarities of the implementation of its individual structural elements have been determined. The author's vision of the essence of the administrative and legal status of refugees and internally displaced persons has been provided.В статье исследованы особенности административно-правового статуса беженцев и вынужденных переселенцев

У їх функціонуванні виділений такий напрям як компетенція в області охорони громадського порядку і безпеки. Визначені шляхивдосконалення компетенції органів внутрішніх справ у сфері охорони громадського порядку і безпеки.Attention on the analysis of role and value of organs of internal affairs is concentrated in the article. In their functioning such direction as jurisdiction is selected in area of public law and safety enforcement. The ways of improvement of jurisdiction of organs of internal affairs are certain in the field of public law and safety enforcement. Relevance of the chosen topic due to the objective necessity of strengthening and deepening public order and security, which means increasing the role of law enforcement, first of all bodies engaged in it, that of the Interior, with readings to determine their competence in the study area. The purpose of this article is to study the jurisdiction of the Interior in the field of public order and security. To achieve this goal it is necessary to solve the following tasks: define the legal nature of the capabilities of the Interior to protect public order; highlight the classification of the Interior, depending on the amount of power to public order and security; identify ways to improve the competence of internal affairs in the field of public order and security. The conclusions are that on the basis of the system analysis capabilities of police, used in the protection of public order, to the following conclusions: the problem of public order determines participate in its decision together specific capabilities of the Interior. However, the main forces are subdivisions patrol police reorganization process which requires its logical conclusion; for the functions and implementation of competence of the Interior should ensure efficient interaction of subjects of the MIA. Such cooperation should be based on a system of principles that formed simultaneously with the development and reorganization of the entire system of law enforcement.В статье сконцентрировано внимание на анализе роли и значения органов внутренних дел.

Physics and chemistry of producing silicon-hydroxylapatite-titanium composite materials

In the research, Si-HA poweders have been synthesized using SBF solution with different content of silicon. It was found that all the samples synthesized from the model solution of extracellular fluid under varying concentration of silicate ions are single-phase and repesent hydroxyapatite. The nature of the reagent containing SiO[44]- ions does not affect the hydroxyapatite structure. In the study of the surface and morphological characteristics of the phosphate coatings modified by silicon ions, it was found that as the degree of phosphate calcium substitution by SiO[44]- ions increases, the surface wettability on the titanium substrates deteriorates and cohesive energy decreases. It is shown that the titanium coating is formed in three stages. After irradiation of titanium substrates coated with Si-HA, the crystals can keep growing and the surface can keep regenerating

Chemical weathering of lower paleozoic black shales of south Sweden

Lower Paleozoic black shales are widespread in Sweden and form part of the Baltic paleobasin, which deposits are also known in Estonia and the Leningrad Oblast of Russia. These rocks are enriched in a carbon substance and characterized by the significant content of uranium, vanadium, molybdenum, copper, nickel, cobalt, zinc, and lead. Black shales contain high levels of Sr – 968; Ba – 337; U – 229; V – 509; Mo – 165; Zn – 411; Ni – 214; Cu – 112 (ppm) in secondary minerals composition formed on their surface. Retrograde diagenetic conditions facilitate the black shales chemical weathering. Elements of the first (U), second (Mo, Sr, Zn), and third (V) hazard classes are washed out of black shales and secondary minerals and can further enter biological cycles

Global corporations and smaller actors in textile business: European perspective

Earlier in Europe, there existed many local textile brands and manufacturers. However, these have experienced significant pressure from the rapid expansion, and success of the European based global textile industry corporations, such as H&M and Inditex (Zara). Their further advancement is supported by the expansion into the new locations and application of nearshoring strategies to the favourable markets, such as Russian, which have attracted to some extent previously entirely offshored European manufacturing located in China. In this regard, the objective of the current study is the assessment of the business activities of the given companies, as well as one company from Finland, and three major textile companies from the Baltic States, through the designed methodological approach. Due to the fact that most performance indicators of companies are based on empirical data, the study is explorative in its nature. Moreover, it shows the relationship between the main key performance indicators of the company with one of the functional areas of logistics (warehousing and inventory management). In particular, analysis of this research shows that two global actors (H&M and Inditex) have experienced exceptional growth, profits and profitability during the years 2001–2016. It was concluded that nearly all of these earlier successful ones and smaller actors have faced difficulties in the past decade, and best growing has been company concentrating on warehousing and retail, instead of manufacturing. Most of these smaller actors have faced profitability challenges, and considerable amount of shareholder value has been lost during the decade. © Hilmola O.-P., Tolli A. & Panova Yu. Text. 2019
