Abstract
Focused on the common problem of easy buckling of specimens in the tension-compression axial stress control fatigue test of automobile sheet steel, a stress fatigue test method for thickness less than 2.5 mm was proposed. For two kinds of automobile sheet materials with different strength levels and thicknesses, fatigue specimens with different widths of test section, parallel lengths, and fillet radii are designed. Without the anti-buckling device, high-cycle fatigue tests with a stress ratio Rs = −1 at different stress levels were carried out, and the shape and size of the fatigue specimens of automobile sheet materials were determined by the number of fatigue life cycles of specimens with different sizes under the same stress cycle form. The results show that for automobile sheet steel with a thickness of 1.0–2.5 mm, the recommended sizes of the uniform-gauge fatigue specimens are width of test section w = (1–3) t, parallel length Lp = (1–3) w, and fillet radius r = (3–10) t. For automobile sheet steel with a thickness less than 1 mm, because the time-displacement curve jitters during the test, it is recommended to install an anti-buckling device, specifically the anti-buckling device with mortise and tenon structure by self-design and with a flattop structure recommended by ISO 1099-2017, Metallic Materials—Fatigue Testing—Axial Force-Controlled Method.

Abstract: Separation of phenolic compounds mixture namely: phenol, resorcinol, Bisphenol A from dilute aqueous solutions by polymer inclusion membrane using Cellulose triacetate (CTA) as support was investigated as a means of recovering Bisphenol A from mixture of phenolic compounds. The effects of parameters influencing the separation performance were studied in terms of permeation flux and selectivity. For competitive transport of phenols across PIM with RC8 + NPOE, the selectivity order was Bisphenol > Phenol > Resorcinol. The high permselectivity of the membrane to Bisphenol A was primarily due to its high affinity towards calixresorcinarene macrocycle. This is of particular interest from an industrial point of view because the enriched phenol permeate can be easily recovered upon phase separation. The prepared PIM were characterized by using Raman spectroscopy, XPS and scanning electron microscopy (SEM) techniques.

OBJECTIVES
This study aimed to provide real-world evidence on coronavirus disease 2019 vaccine effectiveness (VE) against symptomatic infection and severe outcomes caused by Omicron in children aged 5 to 11 years.

METHODS
We used the test-negative study design and linked provincial databases to estimate BNT162b2 vaccine effectiveness against symptomatic infection and severe outcomes caused by Omicron in children aged 5 to 11 years between January 2 and August 27, 2022 in Ontario. We used multivariable logistic regression to estimate VE by time since the latest dose, compared with unvaccinated children, and we evaluated VE by dosing interval.

RESULTS
We included 6284 test-positive cases and 8389 test-negative controls. VE against symptomatic infection declined from 24% (95% confidence interval [CI], 8% to 36%) 14 to 29 days after a first dose and 66% (95% CI, 60% to 71%) 7 to 29 days after 2 doses. VE was higher for children with dosing intervals of ≥56 days (57% [95% CI, 51% to 62%]) than 15 to 27 days (12% [95% CI, −11% to 30%]) and 28 to 41 days (38% [95% CI, 28% to 47%]), but appeared to wane over time for all dosing interval groups. VE against severe outcomes was 94% (95% CI, 57% to 99%) 7 to 29 days after 2 doses and declined to 57% (95%CI, −20% to 85%) after ≥120 days.

CONCLUSIONS
In children aged 5 to 11 years, 2 doses of BNT162b2 provide moderate protection against symptomatic Omicron infection within 4 months of vaccination and good protection against severe outcomes. Protection wanes more rapidly for infection than severe outcomes. Overall, longer dosing intervals confer higher protection against symptomatic infection, however protection decreases and becomes similar to shorter dosing interval starting 90 days after vaccination.

AbsztraktA tanulmány három, a szobi kelta temetőből a Magyar Nemzeti Múzeumba került edényt mutat be, amelyek ugyan nem ismeretlenek a tudományos közönség számára, és különböző aspektusokból korábban már többen foglalkoztak velük, de a minden részletre kiterjedő publikálásuk eddig még nem történt meg. A leletek a magyarországi késő vaskor kutatásának egyik kulcsfontosságú lelőhelyéről kerültek napvilágra, éppen ezért a rövid tanulmány célja az eredeti dokumentációk áttekintésén és a modern digitális módszereken alapuló szakszerű közlés, valamint az újabb adatokon és jelenlegi kutatási eredményeken alapuló kontextusba helyezés.In the focus of this paper stand three remarkable vessels with characteristic decorative elements of the late Iron Age, associated with the La Tène material culture of Central and Eastern Europe. The finds from one of the key sites of the late Iron Age research in Hungary were brought to the Hungarian National Museum from the cemetery of Szob. These pots are not unknown to the scientific community, they have been dealt with in various aspects in the past. However, the full details have not yet been published. The aim of this short study is to publish these vessels precisely, based on a review of the original documents and using modern digital methods. It also examines and contextualizes these important findings in the light of recent data and research.
Az avar centrum és a bizánci periféria •
Authors: Szenthe Gergely 
Published: March 2023

AbsztraktA késő avar ornamentika összképe erős antik hatás alatt alakult ki. A tanulmány a késő avar kori díszítőművészetben megjelenő, antik típusú, valószínűleg bizánci eredetű alakokat és jeleneteket veszi sorra. Közülük más-más típusúakkal találkozunk a késő avar kor elején, valamint közepén és második felében, és úgy tűnik, hogy e két csoport esetében az avar környezet adaptációs mechanizmusai is különbözőek. A korábbi csoport erősebb avar adaptációs hatásnak kitett motívumaival szemben a későbbi csoportra kifejtett hatás minimálisnak tűnik, és nem világos, hogy a mediterrán kultúra irányából furcsának tűnő néhány egyedi jelleg hol került a jobbára övdíszeken ismert ikonográfiába. A két csoport közötti különbség hátterében valószínűleg azon kihívások változása áll, amelyekre az avar társadalom kulturális eszközökkel kísérelt meg választ adni.The overall picture of the Late Avar decorative art was formed under a strong antique influence. The paper discusses antique-type figures and scenes that appear in Late Avar decorative art, probably of Byzantine origin. At the beginning and in the middle–second half of the Late Avar period, there are two different groups of figures and scenes while the adaptive mechanisms of the Avar culture were also different in their case. In contrast to the motifs of the earlier group, which were subject to a stronger Avar influence, the Avar adaptation in the later group seems to be minimal, and it is not clear where some of the features that seem unusual from the context of Mediterranean culture have been incorporated into the iconography, which is mainly known from belt decorations. The differences between the early and late groups are probably due to changes in the challenges to which the Avar society attempted to respond through cultural means.
Actual Problems of Imposing Administrative Responsibility for Advertising Services for Preparation and Writing Research Papers Provided for by the State Scientific Certification System
Authors: Kiselev A. S. , Ledashchev S. V. , Petrov A. M. 
Published: March 2023

The paper examines actual problems concerning administrative responsibility for advertising services in the field of preparation and writing papers provided for by the state scientific certification system In recent years, there has been an increase in the number of organizations engaged in illegal preparation of term (year) papers and theses, research articles and Cand. Sci. dissertations. Unfortunately, as practice shows, territorial bodies of the Federal Antimonopoly Service of the Russian Federation (FAS territorial bodies) do not always identify the elements of the crime in the activities of such organizations.FAS territorial bodies refer to the lack of a high level of experts in the field, difficulties associated with conducting linguistic forensic expertise mandatory for fixing and detecting hidden advertising, the lack of a well-developed mechanism for bringing to administrative responsibility. The authors propose measures necessary to eliminate these problems and improve the work of law enforcement agencies.In particular, the authors are convinced that in a separate letter, the Federal Antimonopoly Service of the Russian Federation should oblige its territorial authorities to identify elements of illegal advertising during their inspections aimed at checking compliance with the Federal Law on Advertising and to bring to administrative responsibility citizens, officials and legal entities advertising services for writing scientific papers. The police bodies, as well as the Federal Tax Service agencies should also be involved in this work, and they should be given the appropriate powers.It is advisable for the Prosecutor General’s Office of the Russian Federation to instruct subordinate prosecutor’s offices of constituent entities, cities, districts to carry out monitoring regarding situations when antimonopoly authorities impose or fail to impose administrative responsibility on citizens, officials and legal entities for advertising services for writing papers provided for by the state system of scientific certification.To identify signs of veiled advertising, it is proposed to use clarifications of the Presidium of the Supreme Arbitration Court of the Russian Federation, according to which courts can take into account information that consumers associate with goods in circulation. In relation to the problem of advertising services for the implementation and writing of scientific papers, antimonopoly authorities can use the data of sociological surveys of students and teachers and the conclusions of linguistic expertise.
Legal Regulation of Relations in Parallel Imports. The Experience of Eurasian Region States
Authors: Ivliev G. P. , Shakhnazarov B. A. 
Published: March 2023

Parallel imports as a tool for the international trade development and better availability of goods in different countries and in some sense an instrument of international competition, give rise to a number of legal issues, the solution of which depends on the stability of trade relations, availability of goods in the markets of different states, compliance with the intellectual rights of copyright holders. The authors analyze legal approaches to parallel import and the problem of exhaustion of rights in the states of the Eurasian region using Russia, Armenia, Kazakhstan, Azerbaijan and the EAEU as case studies. It is noted that there is no normative consolidation of the concept of «parallel import» at the level of international level. There are no international legal grounds allowing the right holder to prevent introduction of the international principle of exhaustion of rights in full in a particular State. The standards of significant difference in the implementation of the international principle of exhaustion of rights seem permissible for regulatory consolidation only in cases where significantly different goods are distributed by the rightholder in at least two States and have ever been imported by the rightholder or with his consent for distribution to the State introducing parallel imports. Even in this case, introduction of the standards of significant difference remains at the discretion of the State introducing the international principle of exhaustion of rights.The regional principle of exhaustion of exclusive rights within the EAEU, can serve as an important mechanism for completing the markets of goods and services in the EAEU member states, filling in the missing goods on the market of the EAEU member states, increasing competition and optimizing prices for goods in the region At the same time, it is necessary to provide for the possibility of using the international principle of exhaustion of exclusive rights, clearly establishing the list of goods (trademarks) subject to its operation.
Constitutional Legal Relations Constructs in the Law of Germany, Great Britain and France
Authors: Lungu E. V. 
Published: March 2023

The science of constitutional law lacks universal theoretical approach to constitutional legal relations; each state independently determines the goals, object and subject of constitutional legal relations. At the same time, the same subjects in different conditions existing in different national legal systems can act as objects and subjects of legal relations. The constitutional legal relations constructs under consideration do not consider a nation as an equal participant in these legal relations. Their role in all of the presented constructs is limited both in terms of the circle of persons and the possibilities to enter into constitutional legal relations as a subject. It can be argued that, despite the difference in approaches to the object and subject composition of legal relations, in Germany, Great Britain and France, such legal relations between public authorities can exist only in a normally developing state (a state that is not under pressure from any crisis or epidemic).The author draws her conclusion based on an analysis of the basic constructs of legal relations, which in Russian legal science are usually referred to as constitutional legal relations. The author’s choice of constructs developed in Germany, Great Britain and France is due to the wide spread in the world of scientific views formed within the framework of the national scientific schools of these states, as well as the influence of the philosophy of law of Germany and France on the formation of constitutional legal relations in Russia.The author pays special attention to the prevalence of Karl Schmitt’s views on the formation of constitutional legal relations in Europe and North America in terms of intolerance of dissent, the assumption of constitutional dictatorship, the strengthening of executive power at the expense of the legislature.
Some Ethical and Legal Challenges in Effective Long-Term Care System Development
Authors: Dzgoeva F. O. 
Published: March 2023

The Russian social protection system of recent years has been characterized by the chaotic nature of the ongoing reforms, which sometimes have the main task of solving momentary economic problems. An increase in the level of social benefits or the introduction of new ones occurs, as a rule, for the most active and dissatisfied part of the population. Thus, in 2019, under the influence of public associations of parents of disabled children, the compensation payment for this category of citizens was increased to 10,000 rubles, while the payment to caregivers for other categories of people in need (for example, elderly relatives) remained at the level of 1,200 rubles per month.The obvious lack of general principles for the provision of state aid based on ethical norms understandable to society causes discontent and distrust of the population. The paper attempts to point out the inconsistency of legislation with moral and ethical standards in the field of long-term care, identify shortcomings and develop some proposals for improving the current legislation.The author suggests the following: 1) to support the idea implemented in pilot projects of a number of subjects of the Russian Federation to endow persons caring for relatives with the status of social workers; 2) to raise the amount of payments to unemployed able-bodied caregivers to the minimum wage, since compensation payments by their nature are designed to replace missing earnings; 3) to eliminate unjustified differentiation of payments depending on the status of persons in need of care; 4) to provide for the possibility of working on a part-time basis when providing care, setting fair limits taking into account the amount of compensation payments and income received, etc.

Objetivou-se avaliar o desempenho da adição de uma cepa de levedura isolada do líquido ruminal de ovino hígido na dieta de cordeiros desmamados e alimentados com feno de Urochloa decumbens. No estudo, foram utilizados doze cordeiros, Santa Inês x Dorper, recém-desmamados. Os animais passaram por um período de adaptação referente às instalações (15 dias) e por dois períodos de experimentação (42 dias). O experimento foi conduzido em parcelas subdivididas, para avaliar o desempenho de um grupo de animais recebendo a levedura e outro grupo controle recebendo o meio de cultivo sem a levedura. Nas subparcelas foram avaliados dois períodos de 21 dias. Os cordeiros suplementados com a levedura apresentaram maior ganho de peso diário (± 243,3 g/dia), em comparação àqueles não suplementados (± 189,8 g/dia), (teste de Wilcoxon, p< 0,10). Foi constatado maior consumo de matéria seca no segundo período (21-42 dias) para os animais suplementados com a levedura (P < 0,05). Entretanto, não houve interação significativa entre os tratamentos e os períodos para peso vivo final e ganho de peso médio diário, além disso não foram evidenciadas diferenças significativas para a conversão alimentar. Neste estudo se constatou que, a suplementação dessa cepa de levedura para cordeiros desmamados estimula o consumo de dieta contendo forragem tropical de baixa qualidade.

Abstract
The objective of this study was to evaluate the performance of the addition of a yeast strain isolated from the rumen fluid of healthy sheep in the diet of lambs weaned and fed with Urochloa decumbens hay. Twelve Santa Inês x Dorper lambs were evaluated. The animals underwent an adaptation period regarding the facilities (15 days) and two experimentation periods (42 days). The experiment was carried out in split plots, to evaluate the performance of a group of animals receiving the yeast and another control group supplemented with the sterile culture medium. In the subplots, two periods of 21 days were evaluated. Lambs supplemented with yeast showed greater daily weight gain (± 243.3 g/day), compared to those not supplemented (± 189.8 g/day), (Wilcoxon test, p < 0.10). Higher dry matter intake was observed in the second period (21-42 days) for the animals supplemented with yeast (P < 0.05).
