dc.description.abstract

value:
In connection with the COVID-19 pandemic, restrictions were introduced in many countries
based on the priority of public interests over personal freedom, national relations over international
relations. The article draws attention to the difficulties that states have begun to experience
in connection with the outbreak of the COVID-19 pandemic. In addition to the significant
damage to the economy, the process of centralization of power and the suppression of the rule
of law has increased. Isolation has had a significant impact on the functioning of European and
national institutions. The European Law Institute has developed a special instrument that could
become a kind of instruction or guide to action for states in a crisis in order to preserve democracy,
the rule of law, as well as justice in human relations. This document is based on the demonstration
of the need to comply with the fundamental principles required by the rule of law.
The authors of the article are members of the European Law Institute, an international organization
of legal practitioners and scholars. The main goal of the organization is to provide a common
platform for all European countries to develop a legal culture. The article provides an analysis
of all 15 principles of the European Law Institute, which are intended not only for member
states of the European Union, but also for other democratic rule-of-law states. Human rights
have become the main targets of the pandemic. According to the authors, this article should
arouse the interest of scholars to discuss the principles of the European Law Institute, which are
designed to remind people about the observance of the rule of law in a crisis.

dc.description.abstract

value:
Given that continental civil law scholarship applies the concept of good faith in either a subjective
(honesty in fact) or objective sense (good faith and fair dealing), the present article focuses
on the latter one. The traditional view in England and Wales discards the recognition of a general
principle of good faith and fair dealing in English law. English courts have adopted a piecemeal
solutions approach (as shown by the judicial decisions issued in Interfoto Picture Library (1987)
and Walford v. Miles (1992)). Meanwhile, the principle in question, along with the concept of the
freedom of contract, is one of the most important principles of the continental civil law tradition
(cf. art. 1104 of the French Civil Code, § 157, § 242 of the German Bürgerliches Gesetzbuch,
art. 2 (1) of the Swiss Zivilgesetzbuch, art. 6:2 Burgerlijk Wetboek, art. 5 of the Polish Civil Code,
art. 2 (1) Common European Sales Law, art. 1:201 Principles of European Contract Law, art. III-
1:103 Draft Common Frame of Reference). The current work analyzes recent English case law
(in particular Yam Seng (2013)), which seems to acknowledge the principle of good faith and fair
dealing while rejecting the traditional view mentioned above. The comparative approach — references
to American, and Commonwealth law, as well as to that of particular European states —
is taken into account. The author claims that hostility to the concept of good faith in an objective
sense in English law is superficial. One may expect that in the near future courts in England
and Wales will follow the path taken by courts in the United States (§ 205 of the Restatement
(Second) of Contracts (1981)), Australia (Renard Constructions (1992)) and Canada (Bhasin v.
Hrynew (2014)), and they will finally recognize good faith as an underlying principle.

dc.description.abstract

value:
The author of this article analyses the problem of motives for entering into a contact and their
legal significance and systematically considers the impact of an error in motive on the legal
validity of a contract in German law as well as in Russian law. In German law, an error in the
properties of a person or an object is regarded by some experts as a mistake in the motive that
testifies to its legal significance. In Russian law, in addition to an error in the object, the mistake
in the motive is an error in regard to a circumstance that a party mentions in its expressed will or on which it bases itself evidently to another party when entering into a contract. The article
also explores situations of subsequent failure to fulfill the motive in light of national (German and
Russian) doctrines of the influence of a subsequent change of circumstances on the contract’s
fate. The author concludes that the criterion which make it possible to distinguish a legally relevant
motive from motives that have no legal significance is characteristic of the causality of
the motive. The causality of the motive presumes that such a motive served as a key factor in
predetermining the decision of the interested party to enter into a contract. It is the error in the
causal motive or its subsequent non-implementation that affects the dynamics of the contract
and it can lead to the effective avoidance of a contract or its termination (alteration) accordingly.
The author also compares the consequences of non-implementation of a motive in civil
law and the English doctrine “frustration of purpose”. In English law, non-implementation of a
motive according to the doctrine of “frustration of purpose” leads to the automatic termination
of a contact. On the basis of mentioned research, the author concludes that the common
criterion in civil and English law that stipulates the legal effect of the error in motive or its nonimplementation
is the causality of the motive.

dc.description.abstract

value:
The development of Russian civil law allows us to conclude that such an institution of the general
theory of civil law as real obligations (obligatio propter rem) is no stranger to domestic
law. At the same time, the existence of some relevant legal rules in federal laws and the recent
jurisprudence of the Supreme Court of the Russian Federation allows us to confirm the conclusion.
It demonstrates that there are more and more examples of real obligations in Russian law.
Meanwhile, the possibility of the very existence of real obligations in Russian law remains a controversial
issue in the Russian civil law doctrine. In the article, the author, raising the question of
the permissibility of the existence of real obligations, systematically analyzes possible dogmatic
and political-legal arguments, the answers to which make it possible to find the place of real obligations
in the system of Russian civil law. At the beginning of the work, the author turns to the
dogmatic grounds for substantiating real obligations. Thus, the author reveals the importance
of the structure of the system of property law, the principles of numerus clausus and numerus
apertus, the properties of following the law, and of the principle of privity of contract for the
existence of the real obligations in the given legal order. In the second part of the article, the
author tries to provide a political-legal justification for real obligations. The author compares the
legal possibilities that are provided, on the one hand, by the use of real obligations in civil law
transactions, and, on the other hand, by the use of limited real rights (for example, servitudes),
legal restrictions on property rights and social norms (neighborly norms). In the final part of the
article, the author summarizes the conclusions made in the article, coming mainly to the general
conclusion that Russian private law does not contain serious dogmatic and political-legal
preclusions to the existence of real obligations in the domestic legal order.

dc.description.abstract

value: В компаниях, находящихся на периферии Цифровой Воронки  (производственные и нефтедобывающие) и основой которых являются нецифровые активы, цифровая трансформация (далее ЦТр) носит вспомогательных характер для существующих производственных процессов и является стратегией дополнительных возможностей. Из-за того, что ЦТр имеет косвенный эффект на процессы производства, производственные компании нуждаются в большем исследовании. Только после реализации мероприятий в рамках Подготовительного этапа ЦТр компания может начинать инвестировать средства в проект по цифровизации, поэтому оценка цифровой зрелости компании является очень важным мероприятием и нуждается в научном исследовании. От правильности определения стратегии и направления проведения ЦТр, зависит успешность реализации полного цикла цифровизации на предприятии. На основе изучения и анализа существующих подходов к определению этапов ЦТр (PriceWaterhouseCoopers, Cetera, Business Consulting Group) составлена расширенная модель этапов ЦТр. Изучен метод оценки цифровой зрелости основанный на Комплексной Модели Производительности и Зрелости (CMMI) и проведена оценка цифровой зрелости предприятий ГК «Ростех» и ПАО «Газпром».

dc.description.abstract

value: The aim of the study is to improve the performance of thin-film composite (TFC) membraneswith  a  thin selective  layer  based  on  chitosan (CS) via different  approaches  by: (1) varying  theconcentration of the CS solution; (2) changing the porosity of substrates from polyacrylonitrile (PAN);(3) deposition of the additional ultrathin layers on the surface of the selective CS layer using interfacialpolymerization and layer-by-layer assembly. The developed membranes were characterized bydifferent methods of analyses (SEM and AFM, IR spectroscopy, measuring of water contact anglesand porosity). The transport characteristics of the developed TFC membranes were studied inpervaporation separation of isopropanol/water mixtures.  It was found that the application of themost porous PAN-4 substrate with combination of formation of an additional polyamide selectivelayer by interfacial polymerization on the surface of a dense selective CS layer with the subsequentlayer-by-layer deposition of five bilayers of poly (sodium 4-styrenesulfonate)/CS polyelectrolyte pairled to the significant improvement of permeance and high selectivity for the entire concentrationfeed range. Thus, for TFC membrane on the PAN-4 substrate the optimal transport characteristics inpervaporation dehydration of isopropanol (12–90 wt.% water) were achieved: 0.22–1.30 kg/(m2h),99.9 wt.% water in the permeate.

The NA61/SHINE experiment at the CERN SPS is performing a uniqe study of the
phase diagram of strongly interacting matter by varying collision energy and
nuclear mass number of colliding nuclei. In central Pb+Pb collisions the NA49
experiment found structures in the energy dependence of several observables in
the CERN SPS energy range that had been predicted for the transition to a
deconfined phase. New measurements of NA61/SHINE find intriguing similarities
in p+p interactions for which no deconfinement transition is expected at SPS
energies. Possible implications will be discussed.

Postcollisional granites of the Kokshaal Segment of South Tien Shan comprise about 20 postkinematic intrusions composed of biotite-amphibole granites, biotite granites and Li-F topaz-bearing
leucogranites. The granites were emplaced coevally with tholeiitic mafic rocks and alkaline syenites.
Geochemically the granites are classified as A-type and characterized by elevated Fe/(Fe+Mg) and
K2O/Na2O values and high concentrations of Na2O+K2O, Rb, HFSE. On the discrimination diagrams Y-Nb and Rb-(Y+Nb) compositions of the granites plot into the field of intra-plate granites.
On a regional scale, the compositional variations of the Kokshaal granites can be explained by
fractionation of potassium feldspar and amphibole. The granites were probably derived from the
crustal protoliths represented by Precambrian metamorphic rocks of the Tarim microcontinent.
Crystallization ages of the Kokshaal granites, established utilizing U-Pb zircon dating, fall in the
relatively narrow range between 280 and 295 Ma corresponding to the early Permian, which is in
agreement with ages of postcollisional granites elsewhere in Tien Shan. Genesis of granites was
related to trans-crustal shear zones.

Chapter 1 provides a review of current understanding of geological structure and history of western Tien Shan and spatial distribution and characteristic features of the Paleozoic granitoid series.
Because the main volume of granitoid series of western Tien Shan is represented by postcollisional
magmatic series, models for postcollisional magmatism are specifically described in the second part
of this Chapter. Finally, principles of isotope mapping and interpretation of genesis of granitoid
series utilizing Nd-Sr-Pb-Hf isotopic data, which were applied in this work, are described in the last

dc.description.abstract

value:
The monograph describes the evolution of granitoid magmatism at convergent continental margins during transition from subduction to continental collision in the Hercynian belt of western
Tien Shan. The objects of the study comprised Hercynian granitoids of western Tien Shan. Postcollisional granitoids were studied in the Kyzylkum, Gissar, Alai and Kokshaal Segments of the South
Tien Shan, which formed at a former passive margin of the Turkestan Ocean. Supra-subduction
granitoids and the transition from subduction-related to postcollisional magmatism were studied
in Sultan-Uvais mountains and in the Chatkal-Kurama terrane of the Middle Tien Shan that formed
at the northern active margin of the Turkestan Ocean.
Introductory sections provide a review of current understanding of geological structure and history
of western Tien Shan and spatial distribution and characteristic features of the Paleozoic granitoid
series. Because the main volume of granitoid series of western Tien Shan is represented by postcollisional magmatic series, models for postcollisional magmatism are specifically described in these
sections. Principles of isotope mapping and interpretation of genesis of granitoid series utilizing
Nd-Sr-Pb-Hf isotopic data, which were applied in this work, are described in the introductory sections.
Postcollisional granites of the Kokshaal Segment of South Tien Shan comprise about 20 postkinematic intrusions composed of biotite-amphibole granites, biotite granites and Li-F topaz-bearing
leucogranites. The granites were emplaced coevally with tholeiitic mafic rocks and alkaline syenites.
Geochemically the granites are classified as A-type and characterized by elevated Fe/(Fe+Mg) and
K2O/Na2O values and high concentrations of Na2O+K2O, Rb, HFSE. On the discrimination diagrams Y-Nb and Rb-(Y+Nb) compositions of the granites plot into the field of intra-plate granites.
On a regional scale, the compositional variations of the Kokshaal granites can be explained by
fractionation of potassium feldspar and amphibole. The granites were probably derived from the
crustal protoloiths represented by Precambrian metamorphic rocks of the Tarim microcontinent.
Crystallization ages of the Kokshaal granites, established utilizing U-Pb zircon dating, fall in the
relatively narrow range between 280 and 295 Ma corresponding to the early Permian, which is in
agreement with ages of postcollisional granites elsewhere in Tien Shan. Genesis of granites was
related to trans-crustal shear zones.
The early Permian intrusions of the Alai segment of the South Tien Shan comprise four geochemically contrasting intrusive series, including (1) I-type and (2) shoshonitic granitoids, (3) peraluminous granitoids including S-type leucogranites and (4) alkaline rocks and carbonatites, closely
associated in space and time. New geochronological data indicate that diverse magmatic series of
the Alai segment formed virtually coevally in a post-collisional setting. Five U-Pb zircon rock ages
in the range 287 – 281 Ma, in combination with published ages, define the main post-collisional
magmatic pulse at 290 - 280, which is similar to ages of post-collisional intrusions elsewhere in the
South Tien Shan. The Sr-Nd-Pb-Hf isotopic compositions of the studied intrusions are consistent
with the reworking of crustal material with 1.6 – 1.1 Ga average crustal residence times indicating
the formation of the Alai segment of the South Tien Shan on a continental basement with Mesoproterozoic or older crust. It is suggested that position of the Alai microcontinent between two major
sutures enabled delamination of its lithospheric mantle, which triggered the diverse post-collisional magmatism as a result of interaction of ascending asthenospheric material with lithospheric mantle
and various crustal protoliths.
The Paleozoic evolution of the Southern and Middle Tien Shan terranes in the territory of Uzbekistan is generally associated with the history of two ocean basins - the Turkestan and Paleotethys.
Ages of ophiolites indicate the opening of the oceans in Cambrian – Ordovician, and partial closure with formation of an island arc in the northern part of the basin in Ordovician - Silurian. At
the northern margin of the Turkestan ocean, the northward subduction under the Middle Tien
Shan continued until Devonian, which led to formation of an active margin with granitoids emplaced between 429 and 416 Ma. In the late Devonian, subduction-related magmtism terminated
and the whole region developed as passive margin. Northward subduction resumed in the early
Carboniferous and formed magmatic Andean-type belt exposed in the Chatkal-Kurama terrane.
Late Carboniferous collision resulted in crust thickening and emplacement of postcollisional granitoids. Formation of postcollisional intrusions in different terranes took place in various tectonic
settings. Shoshonitic granitoids of the Chatkal-Kurama terrane formed as a result of slab break off
at postcollisional stage. Voluminous postcollisional magmatism of Kyzylkum can be explained by
delamination of lower crust and its replacement by the material of astenospheric mantle. Coeval
emplacement of geochemically contrasting granitoids in the North Nuratau fault zone could result from contemporaneous melting of different protoliths at different depths in a translithospheric
shear zone.
Thus, in western Tien Shan there established 4 stages of Paleozoic magmatism related to the evolution of the Turkestan paleo-ocean: 1) plagiogranites of ophiolites with ages 506 – 438 Ma; 2)
supra-subduction granitoids with ages in the ranges 429 – 414 and 320 – 300 Ma; 3) postcollisional
granitoids with ages 295 – 280 Ma. Magmatic series of former active margins, exposed in the Chatkal-Kurama, Gissar and Sultan-Uvais, are represented by supra-subduction granitoids of calc-alkaline series (I-type granites) and by postcollisional shoshonitic granitoids. Postcollisional magmatism at former passive margins was controlled by the composition of the basement: homogeneous
A-type granites predominate in the Kokshaal Segment, built up on Precambrian basement, while
varied I- S- and А-type granites formed in the Alai and Kyzylkum Segments with more heterogeneous basements. Most of the granitoids of western Tien Shan were derived from Neoproterozoic
or older continental crust. Granitoids derived from juvenile island arc crust were established only
in northern Kyzylkum and Sultan-Uvais. Postcollisional granotoids formed in various geodynamic
settings. Shoshonitic series of the Chatkal-Kurama were produced from enriched mantle wedge as
a result of slab break-off. Origin and emplacement of intrusions in the Nuratau mountains and in
the Kokshaal Segment was controlled by uplift of asthenospheric material in regional shear zones.
Heterogeneous basement structures of the Kyzylkum and Alai Segments enabled delamination of
the lower crust and its replacement by asthenospheric material.

title: Stephano Torelli’s “Coronation Portrait of Catherine II”:  Crowns as a Visual Formula of the Lands of   the Russian Empire

dc.contributor.author

value: Skvortcova, Ekaterina Aleksandrovna

dc.description.abstract

value:
The “Coronation portrait of Catherine II” by Stephano Torelli introduces a new type of iconography of the Russian Empress in which she appears as a bearer of multiple (i. e. four) crowns. Whereas originally such a portrait type in European art served as a representation of the several titles of the ruler and correspondent lands joined in a personal union, it became a representation of the titles of Catherine II as the Russian Empress and tsarina of the conquered tsarstva of Kazan, Astrakhan and Siberia. The theme of titles and lands of the Empire had already developed in 18th-century Russia in other forms (allegorical figures, coats-of-arms) and visual media (decorative painting and sculpture). Circa 10 examples collected here for the first time are set side by side with their European counterparts. Three types of representations of
native and conquered territories emerged in which the very choice of particular titles and the place of their symbolic representation in composition accentuated different aspects in the concept of the Russian Empire. But it was only with Torelli’s “Coronation Portrait of Catherine II”
that the symbolism of three crowns appeared in Russian portrait painting. Torelli previously worked for the Elector of Saxony and King of Poland, some of whose portraits incorporate two crowns. Another important factor seems to be the fact that such iconography gained special popularity with Catherine’s senior peer Maria Theresia. Only the Habsburgs, the rulers of the Holy Roman Empire, with which a newly established Russian Empire aspired to rival, possessed more than three crowns. The importance attached to symbolism of multiple crowns by Catherine is illustrated by direct mentioning of it in her “Zapiski”.

dc.description.abstract

value: Predominantly, carbon atoms of various species function as acceptors of noncovalent interactions when they are part of a π-system. Here, we report on the discovery of a halogen bond involving the isocyano carbon lone pair. The co-crystallization or mechanochemical liquid-assisted grinding of model mesityl isocyanide with four iodoperfluorobenezenes leads to a series of halogen-bonded adducts with isocyanides. The obtained adducts were characterized by single-crystal and powder X-ray diffraction, solid-state IR and 13C NMR spectroscopies, and also by thermogravimetric analysis. The formation of the halogen bond with the isocyano group leads to a strong reduction of the isocyanide odor (3- to 46-fold gas phase concentration decrease). This manipulation makes isocyanides more suitable for laboratory storage and usage while preserving their reactivity, which is found to be similar between the adducts and the parent isocyanide in some common transformations, such as ligation to metal centers and the multi-component Ugi reaction.

dc.description.abstract

value:
The article examines the problems of doctrinal approaches and practical implementation of the
principle of legal certainty at the stage of verification of judicial acts in civil process. The principle
of legal certainty was accepted by the Russian judicial system with Russia’s accession to the
Council of Europe. The development of this principle has been continued with the assessment
by the European Court of human rights on the effectiveness of verification courts in civil procedural
law. The criteria proposed for compliance with legal certainty have come into conflict
with the need to correct erroneous judicial acts. The extension of the application of the principle
of legal certainty has limited the procedural regimes of the supervisory and then cassation
courts. Such a situation creates the possibility of ignoring judicial errors only on the grounds
that the appealed judicial act has entered into legal force. The author analyzes the current domestic
conditions of judicial verification and the revision of court decisions that have entered
into force. The domestic judicial verification activity is of an urgent nature, which excludes the
indefinite review of the judicial acts that have entered into force, since the implementation of
such a review takes place within a single cycle, involving strict deadlines for appeal and its consideration.
Verification of judicial acts in any member state of the Council of Europe, including
the Russian Federation, is intended to correct significant judicial errors, and only on the initiative
of the persons involved in the case. Given these circumstances, the conclusion can be made
about the inapplicability of the principle of legal certainty as the evaluation of the effectiveness
of the entire system of verification of judicial acts, or parts of its procedural means, and by the
courts in the revision of court decisions that entered into legal force.

dc.description.abstract

value:
The article examines the specificity of the approach to local government in the Russian Federation
in light of current changes in legal regulation of the institution, as well as the interpretation
of the place and role of local government in the system of public authority, determined
by the decisions of the Russian Constitutional Court. The authors maintain that despite the
organizational and functional autonomy from the mechanism of state power declared in the
Russian Constitution, local government should be considered as part of a unified system of
public authority, since the opposite neither reflects the objective conditions of the socio-economic,
political and legal development of the Russian state and society, nor find any historical confirmation or similarities in foreign experience. The affirmation of local government’s place
within a unified system of public authority presupposes a closer and well-coordinated interaction
of the state and municipal levels in addressing issues of both local and national importance.
The latter should also contribute to the positioning of local government as a standalone
element of federative relations, which is important both for the development of municipal
institutions themselves and federalism as a whole. At the same time, the authors stress that
by virtue of its political and legal nature, local government requires the development of direct

dc.description.abstract

value:
The article applies a comparative approach to the issue of directors’ liability for breach of
good faith and unreasonable actions in Russian, UK, and US legislation and case law. During
the analysis of Russian case law, the inconsistency in the judicial approach to the application
of the law has been established and revealed in the article. The author brings up the issue of
whether and to what extent it is possible to apply the objective and subjective tests developed
by English Common law judges to solve the matters of a director’s liability for breach of good
faith in Russia. However, the author draws the line between the above described Common
law perspective and the maxims of the law of equity and offers to restrict the latter. The other
common law doctrines such as estoppel, reasonable man standard, and respondent superior
are also seen in comparison with Russian law. The broader application of the principle of good
faith to corporate relations has been significantly limited in the UK and the USA, the courts
tend to apply fiduciary duties under a minimal scope. The directors’ liability for breach of the
duty of care and duty of loyalty has been in many cases up to shareholders to decide unless
the gross negligence was proven to have caused harm to the company. Generally, however, the
directors are not held liable for pure economic loss and unprofitable deals. Russian courts to
the contrary in many cases hold directors liable for the loss even though directors’ fault, intent
or gross negligence were not proven — the mere fact that the director could not demonstrate
that the best possible course of actions was taken is often regarded as a breach of good faith
and unreasonable actions.

dc.description.abstract

value:
The article examines the problems of the realization of the autonomy of parties in the process
of selecting ways to resolve disputes from public-private partnerships. A public-private partnership
is considered as a type of contractual relationship based on the autonomy of will of
the parties (the autonomy of the parties). The autonomy of the parties is one of the principles
of private relations and is implemented in the material and procedural aspects. The opinion is
expressed that the autonomy of the parties was formed as a principle in not only private, but
also civil procedural and transnational procedural law. In procedural relations, it is expressed
in the freedom to choose the method of resolving a dispute. The procedural autonomy of the
parties is limited by imperative norms of national legislation. A comparison is made of methods
for resolving disputes from public-private partnerships recommended by international
intergovernmental universal and regional organizations and enshrined in domestic and foreign
legislation. The protection mechanisms offered by international organizations are based
on freedom of choice when selecting a method for dispute resolution by the parties, however,
the state may limit the autonomy of the parties in the freedom of choice of procedures. An
assessment is made of the prospects for the use of alternative procedures as an effective means
of resolving disputes between the state and business structures. There is considerable potential
for the extrajudicial procedures in the settlement of public-private partnership disputes. It is
noted that in the legislation of the states that allow a foreign natural or legal person as a public partner, international commercial arbitration is usually introduced into the dispute resolution
system. One of the trends in the development of the dispute resolution mechanism was the
creation of specialized arbitrations for the settlement of disputes in the field of public-private
partnerships.

dc.description.abstract

value:
The article explores some issues of providing professional pastoral care to HIVinfected
hospital patients. Arguments are provided and the validity of the use of
the term “pastoral deontology” is justified. A comparison is made of medical and
pastoral professional activities along the lines of implementing the scenario of the
relationship “providing assistance — receiving assistance”, as well as a comparison
of the principles underlying the performance of medical and pastoral duty. It is
argued that the concept of pastoral deontology in the counseling of people with
chronic and incurable diseases, as a new scientific trend, suggests that this discipline
is akin to medical deontology and should be based on the principles of
medical deontology, but at the same time it should develop the principles in relation
to the practice of pastoral care of sick people. For full cooperation between
the Church and medicine, the help coming from the Church should be built into
existing state medical structures, play a subordinate role to them, have a reliable
working methodological basis, and be set forth in a language that is understandable
to the medical community. At the same time, the methodological basis of pastoral
care for HIV-infected people should be based on the use of the accumulated
theoretical and practical experience of the spiritual care of such people, consist of
behaviors and actions by pastors that will help to establish positive contact with
patients, relieve their stress, inspire confidence in the individual providing assistance,
help patients cope with spiritual problems, and motivate them to receive
treatment prescribed by a doctor. Based on the results obtained during the analysis
of data from surveys of both experts and HIV-infected patients in the hospital, the
article shows that pastoral care for HIV-infected patients by priests of the Russian
Orthodox Church has a positive effect on their physical condition, thanks to mobilization
of the body’s defense system in confronting the infection. This results in
an improvement in the patient’s quality of life and contributes to the development
of motivation to create an optimistic attitude.

value:
The article is devoted to understudied issues in the intellectual heritage of professor
archpriest Dumitru Staniloae, an outstanding Romanian theologian of the twentieth
century. More precisely, the article examines the journalistic articles that reflected
his philosophical, cultural, social, political, and religious views, which as a
whole can be organized into a model of “political ideology”. At the same time, the
author considers the attitude to the issues of combining the Orthodox worldview,
patriotism, and statehood in the context of developing the conceptual and ideological
field of the idea of “Romanism”, which was established in the situation of territorial
and social changes in Romania during the interwar period. In this regard, the
religious “Romanian traditionalism” becomes the key triad of “Orthodoxy — collegiality
— tradition”, which is equally dissociated from the materialistic-atheistic
ideologies of both the democratic West with its individualism and capitalism, and the Bolshevik East with its authoritarianism and collectivism. The views of the Romanian
theologian are presented on the material of some of his publications in the
journal Gândirea and the newspaper Telegraful român. Understanding the specifics
of the ideological field of the Orthodox Romanian national and state self-identification,
in the context of the formation of a new map of Europe in the 30s, can be taken
into account when analyzing elements of the conceptual paradigm of Orthodox
“political theology”.

dc.description.abstract

value:
The author’s aim is to analyse the Gospel of Matthew within the broader literary tradition
of Second Temple Judaism. The Jewish writings produced both in the land of Israel
and in the diaspora from the Hasmonean period until the early Empire help us to
relate Matthew to its social, political and theological context. Surveying some aspects
of the Second Temple Judaism, namely Messianic expectations, Apocalyptic movements
and Scripture interpretation methods, bear valuable evidence on how Matthew
sets the story of Jesus. Treatises of such prolific authors as Philo and Josephus provide
valuable literary parallels as well as an overall outlook on major trends of thought,
that need to be taken into account when interpreting the Gospel of Matthew. Matthew’s
portrait of Jesus as a royal figure, as the legitimate heir of the House of David
is, to some extent, linked with the understanding of kingship during the Hasmonean
period. The kingship motif is prominent for Philo’s De vita Mosis, in which Moses is
treated as king, legislator, priest, and prophet. Comparative analysis leads the author
to the question of whether it is possible to include Matthew, and even the other three
canonical Gospels, within one of the standard collections of Jewish writings?

The article is devoted to the initial period of the relationship between the Russian
Orthodox and Episcopal Church in the USA in the period from 1862 to 1865. After
the end of the war for independence in the United States (1775–1783), Anglicans
of America gained independence from the Church of England and established their
own Episcopal Church in 1784. Faced with difficulties in distinguishing themselves
from numerous Protestant communities and sects, the Episcopal Church took the
initiative to approach the Russian Orthodox Church as the successor of the ancient Universal Church, which had solid dogmatic foundations and a structural basis. The
presence of parishes of the Russian Church on the North American continent contributed
to rapprochement. In 1862, a Russian-Greek Committee was established in
the Episcopal Church for the purpose of establishing friendly relations between the
two denominations. In 1863 and 1864, representatives of the American Church, layman
Roggles and presbyter Jung, came to Russia and met with representatives of the
Russian Church authorities, including Metropolitan Filaret of Moscow, with whom
they discussed possible paths to unity. The interfaith dialogue that had begun was
interrupted in 1865 due to the American Civil War. However, the results achieved
at this first stage of inter-church communion were in demand in the following years
when the Episcopal Church in the USA joined forces with the Church of England
for rapprochement with the Russian Orthodox Church.

This article is devoted to the analysis of the theses described by M. Massa in his
book “The structure of theological revolutions”. This book This book is an introduction
to the problems of the essence of Christian Tradition, natural law and moral
theology, the theology of marriage and its particular aspect related to childbearing.
The article analyzes the main thesis of M. Massa on the example of reception by
American Catholics of the provisions of the encyclical “Humanae vitae”. The thesis
is that in Catholicism there is no single tradition of theology that evolves in the way
T. Kuhn wrote about this in relation to science. For introduction into the context
of the described M. Mass reception of the encyclical “Himanae vitae” the article
describes the history of its occurrence. “Humanae vitae” is compared with papal encyclicals
containing conflicting ideas to the main thesis of this text. By the example
of several authors, to whom individual paragraphs in the “Structure…” by M. Mass
are devoted, this contradiction between the birth of children and their upbringing
is described. In the final part of the article, several conclusions are made: M. Massa,
adapts T. Kuhn’s theory of scientific revolutions to theology, but does not take into
account the specifics of this field of knowledge; the author speaks of the absence of
a unified Catholic tradition of theology; since there is a position about paradigms
changing in theology that are sensitive to the problems of our time, any anti-church
action could find support in church theology. A set of these conclusions allowed
the author of the article to conclude with an assumption about what the tradition
of Orthodox theology should be, so that it is sensitive to the problems of modernity
and at the same time does not lose its identity.

dc.description.abstract

value:
Skeptical theologians widely discuss J. L. Schellenberg’s approach in which he
demonstrates how epistemic skepticism of skeptical theology leads to Divine hiddenness. Although this experience is obviously close to that of godforsakeness (a
strictly religious experience), nevertheless the experience of Divine hiddenness can
lead to the denial of the theistic component of skeptic theism, and, accordingly, to
the destruction of theism (Schellenberg himself adopts an atheistic position). In
our article, we examine the causes of atheistic tendencies within skeptic theism and
offer a proposal to preserve the theistic core of skeptic theism. We use the analysis
of theodicy of the Book of Job (the concept of O. M. Nogovitsyn is the basis for the
interpretation of the book) to indicate the possible cause of this atheistic tendency.
A way to overcome the internal conflict of skeptic theism lies not in denying the
agnostic component of the experience of the hidden God, but in maintaining the
distinction between the name of God and God himself. The name of God reveals
a particular truth about God, but it is essential to understand that God is different
from his name. God appears to Job and presents himself as an absolute precedence,
or a total other — different in relation to his own names.

to the irreducible characters and conjugacy classes. In the present paper, we consider the
group obtained by a group contraction from the general linear group over a finite field. For
this group, we construct a supercharacter theory. In terms of rook placements, we classify
supercharacters and superclasses, calculate values of supercharacters on superclasses.

The paper is devoted to the study of homological properties of quotient divisible Abelian

in recent years. In the first part of the paper, we study the conditions for the vanishing
of extension groups in which one of the arguments is a quotient divisible group. Under
some additional assumptions, groups of homomorphisms from quotient divisible groups to reduced abelian groups are described. Some properties of the universality of quotient divisible
Abelian groups are investigated. The second part of the work is devoted to the study
of the homological properties of compact Abelian groups, which are dual in the sense of
L. S. Pontryagin to quotient divisible groups. Such groups are called quotient toroidal. We
study the conditions for the vanishing of extension groups in which one of the arguments is
a quotient toroidal group. Some groups of continuous homomorphisms in which the second
argument is a quotient toroidal group are described. In the last part of the paper, we study
the conditions for the vanishing of extension groups of quotient divisible groups with the
help of compact quotient toroidal ones. The fundamental group of the topological space of
the quotient toroidal group is characterized.

dc.description.abstract

value:
An elementary net (net without a diagonal) σ = (σij )i =j of additive subgroups σij of the
field k is called closed if the elementary net group E(σ) does not contain new elementary
transvections. Elementary net σ = (σij) is called supplemented if for some additive
subgroups σii of the field k the table (with diagonal) σ = (σij ), 1 ≤ i, j ≤ n, is a (full) net. Supplemented elementary nets are closed. A necessary and sufficient condition for
the supplementarity of the elementary net σ = (σij) is the implementation of inclusions
σijσjiσij ⊆ σij (for any i  = j). In this regard the following question is of interest (Kourovka
notebook, question 19.63): ): is it true that for closedness of an elementary net σ = (σij)
it suffices to execute the inclusions σ2
ijσji ⊆ σij for any i  = j (here, by σ2
ij we denote the
additive subgroup of the field k generated by all squares from σij)? Elementary nets for
which the last inclusions are satisfied we call weakly supplemented elementary nets. The
concepts of supplemented and weakly supplemented elementary nets coincide for fields of
odd characteristic. Thus, the aforementioned question of the sufficiency of weak supplementarity
for the closedness of an elementary net is relevant for fields of characteristic 0
and 2. In this article we construct examples of weakly supplemented but not supplemented
elementary nets. An example of a closed elementary net is constructed, which is not weakly
supplemented.

value:
In 1986, Ya. V. Tatarinov presented the basis of the theory of weakly nonholonomic systems.
Mechanical systems with nonholonomic constraints depending on a small parameter are
considered. It is assumed that when the value of this parameter is zero, the constraints of
such a system become integrable, i. e. in this case we have a family of holonomic systems
depending on several arbitrary integration constants. We will assume that these holonomic
systems are integrable hamiltonian systems. When the small parameter is not zero, the
methods of perturbation theory can be used to represent, to a first approximation, the
motion of the system with nonzero parameter values, as a combination of the motion of
a slightly modified holonomic system with slowly varying previous integration constants
(transgression effect). In this paper, we describe the transgression effect in the problem of
motion of an almost holonomic pendulum.

It is shown that polynomially complete quasigroups with no subquasigroups are quasitermal.
The case of transitive action of the automorphism group on these quasigroups is
considered. In particular the case of quasigroup of a prime power order defined on arithmetic
vector space over a finite field is considered in details. There are found some necessary
conditions under which a multplication in this space given in terms of coordinates corresponds
to a quasigroup. The case of the 2-element field is considered in detalis. In this
case the quasigroup multiplication is given in terms of Boolean function. The is found a
criteria for a quasigroup multiplication. Under some assumptions there are classified up to
an isotopy all quasigroups of order 4 in terms of Boolean function. Polynomially complete
quasigroups play a significant role because the problem of solutions of polynomial equation
in them is NP-complete. This property is important for the securing information, since crypto-transformations are defined in terms of quasigroup operations. The same argument
shows the importance of quasigroups with no proper subquasigroups.

dc.description.abstract

value:
A two-dimensional periodic system of differential equations with two hyperbolic periodic
solutions is considered, it is assumed that heteroclinic solutions lie at the intersection of
stable and unstable manifolds of fixed points, more precisely, the existence of a heteroclinic
contour is assumed. We study the case when stable and unstable manifolds intersect nontransversally
at points of at least one heteroclinic solution. There are various ways of nontransversally
intersecting a stable manifold with an unstable manifold at the points of a
heteroclinic solution. Earlier in the works of L. P. Shil’nikov, S. V.Gonchenko, B. F. Ivanov
and other authors, it was assumed that at the points of non-transversal intersection of a
stable and unstable manifold there is a tangency of no more than finite order. It follows
from the works of these authors that there exist systems in which there are stable periodic
solutions in the neighborhood of the heteroclinic contour. In this paper, heteroclinic contours
are studied under the assumption that at the points of non-transversal intersection of
the stable and unstable manifold at the points of the heteroclinic solution, tangency is not a
tangency of finite order. It is shown that in the neighborhood of such a heteroclinic contour
there is situated a countable set of periodic solutions whose characteristic exponents are
separated from zero.

This paper contains an explanation of Ramanujan-type formulas with cubic radicals of cubic

We give a complete description of formulas of such type, answering the Zippel’s question.
It turns out that Ramanujan-type formulas are in some sense unique in this situation. In
particular, there must be no more than three summands in the right-hand side and the
norm of the irrationality in question must be a cube. In this situation we associate with
cubic irrationalities a cyclic cubic polinomial, which is reducible if and only if one can
simplify the corresponding cubic radical. This correspondence is inverse to the so-called
Ramanujan correspondence defined in the preceding papers, where one associates a pure
cubic extension to some cyclic polinomial.

dc.description.abstract

value:
In this paper, an automatic control discrete-time system of the second order is studied. Nonlinearity
of this system satisfies the generalized Routh—Hurwitz condition. Systems of this
type are widely used in solving modern applied problems of the theory of automatic control.
This work is a continuation of the research presented in the author’s paper “On the problem
of Aizerman: Coefficient conditions for an existence of four-period cycle in a second-order
discrete-time system”, where systems with two-periodic nonlinearity lying in the Hurwitz
angle are studied. In the referenced paper, the conditions on the parameters under which a
system with two-periodic nonlinearity can have a family of non-isolated four-period cycles
are indicated and a method for constructing such nonlinearity is proposed. In this paper, it
is assumed that the nonlinearity is three-periodic and lies in the Hurwitz angle. The system
is studied for all possible values of the parameters. We explicitly indicate the conditions
on the parameters under which it is possible to construct such a three-periodic nonlinearity
that the system with specified nonlinearity is not globally asymptotically stable. It is
shown that a family of three-period cycles and a family of six-period cycles can exist in
the system with indicated nonlinearity. A method for constructing such nonlinearities is
proposed. The cycles are not isolated, any solution of the system with the initial data lying
on some specified ray is periodic.
