This article presents the information on the valorization of waste generated during the production of tissue paper. The possibility of bioconversion of the polysaccharide part of paper sludge into simple sugars has been evaluated. The options for processing the paper sludge before enzymic hydrolysis to achieve the maximum yield of monosaccharides have been considered. Pretreatment with acids has been found to be a key step before the biocatalytic cleavage of waste polysaccharides. An additional yield of enzymic hydrolysis products after pretreatment with acids has been obtained by pre-extraction of the paper sludge with spirit or acetone. It has been established that the most intense enzymic hydrolysis of readily available fractions of the paper sludge takes place in the first 10–12 hours. Further, the process slows down, probably due to the action of the remaining components of the fillers, as well as an increase in the proportion of the difficult-to-hydrolyze polysaccharide part. In all cases, the proportion of absolutely dry non-hydrolyzed residue has been about 43±2 % of the dry matter of the paper sludge. The main products of enzymic hydrolysis have been glucose and xylose. The resulting sugars have been used for mixotrophic cultivation of the Tetradesmus obliquus and Chlorella vulgaris algae. Yeast strains have been selected for the conversion of monosaccharides from the paper sludge. In a series of experiments on non-sterile yeast cultivation, the Candida utilis PAL D and Debaryomyces hansenii SWING R cultures have turned out to be the most productive (within 2.10±0.14 g of air-dry yeast weight/dm3 per 24 hours). The degree of conversion of hydrolysate sugars has been 70±2 %. Most of the remaining sugars (about 80 %) have been represented by xylose. Complete utilization of the sugars has taken place on the 2nd day when having added an extra nitrogen source to the medium. On the other hand, the spent nutrient medium after yeast separation has been suitable for mixotrophic cultivation of microalgae. It has been revealed that the economic costs of pre-treatment of the paper sludge with nitric acid can be leveled by using the resulting salts as a nitrogen source for cultivating yeast. In doing so, the yield of yeast biomass increases by almost 2 times.

The article introduces attraction marketing methods employed by Russian monthly popular science magazine Diletant. The authors compared the printed version and the website. The paper magazine attracts the reader mainly by the topic name printed on its cover as a unique creolized text. The further semantics of the front media text includes various aspects of the main topic. Color highlights both topical issue and regular features. The comparative analysis with the online version revealed some significant differences. The website has a muted color scheme and minimal animation; it contains neither video nor audio materials. Like in the printed version, the function of attraction belongs mainly to illustrations and subtitles. Online Diletant is interactive in navigation, tests, and surveys, which are, however, the only form of interactivity: the site does not provide comments, forums, “likes”, etc. Such limited use of attention-seeking tools makes the digital version of Diletant uncompetitive and inferior to its paper issue.

The paper considers the question that has gained relevance in the last decade: whether the cryptocurrency bitcoin is money. The economic literature provides different opinions on this issue. The analysis shows that disagreements arise because of the different understanding of the category of ‘money’ rather than because of the nature of bitcoin. The author analyzes popular interpretations of money in terms of their applicability to the definition of the role and place of cryptocurrencies in the financial system. The purpose of this study is to define money as a financial instrument that linksthe creation of gross social product with its distribution. The author believes that money emerged and exists as a tool that ensures a connection between the contribution of each economic entity to the total product of society and the right to receive an equivalent amount of goods from this gross product. At the same time, the author defines money as an ‘ideal right’ to receive a share of the gross social product. In this regard, the analysis of bitcoin shows that this cryptocurrency allows obtaining goods from the gross social product in many countries, while bitcoin owners do not contribute to the gross social product. Based on this, bitcoin cannot be considered money; it is a money substitute, or surrogate money. At the same time, bitcoin was created as money and performs the functions of money, but to a limited extent. Bitcoin can only perform the functions of money as a supplement to an existing official currency. It is not capable of functioning as the only currency in a society. The interpretation proposed in this paper can be used for the purposes of developing the Russian law on cryptocurrencies is currently being worked on by the Government and the Central Bank of Russia.

Continuity of generations is a very serious issue for Harbin residents. Harbin residents have always tried to preserve the memory of their ancestors. Preserving the history of Russian emigration has a high relevance of the problem. The history of many Russian families is connected with Harbin, where there was the largest Russian diaspora. Nowadays this city is the administrative center of the Chinese province of Heilongjiang. We should not forget about the people who built the Chinese Eastern Railway, as well as about the Russian emigrants who lived in Harbin, but kept the image of Russia in their hearts and contributed enough to Russian culture and science. The purpose of this paper is to study the Russian emigrants life in Harbin and to restore contact with their descendants. The article uses historical and system analysis and bibliographic research method. The paper tells about the amazing life of Nikolai Nikolaevich Znamensky: his childhood in Harbin, his relatives, his move to the USSR, his admiration of nowadays China, and also focuses on the message of Nikolai Nikolaevich Znamensky to modern Harbin residents.

INTRODUCTION. This paper reflects historical overview of long-standing emergence of mechanisms of judicial protections of patent rights conferred by European patens which begun even in 1950-s and ended with start of operations of the Unified Patent Court in 2023. The paper demonstrates that the establishment of the similar mechanism within the Eurasian Patent Organization or Eurasian Economic Union may require different approaches because of possible centralization of industrial property protection under Eurasian Patent Organization.METHODS AND MATERIALS. The research materials for this paper are scientific works of foreign and Russian scientists and officials of the European Patent Office and the Eurasian Patent Office, legal acts of international and regional levels and drafts thereof. Methodological basis of this research are general and special scientific methods.RESEARCH RESULTS. This paper suggests periodization in emergence and evolution of dispute resolution mechanisms for European patents, reveals rationales for establishment of the unified patent judiciary in Europe and outlines directions for further research of prospects of creation of the similar mechanism in the Eurasian region. Some findings made in this article may facilitate the growth of such researches.DISCUSSION AND CONCLUSIONS. European Union (EU) accumulated broad experience in establishment of the dispute resolution mechanisms for European patents. Due to uniqueness the Unified Patent Court is of great interest when researching prospect of improvements of the patent judiciary and quasi-judicial mechanisms under the Eurasian Patent Convention. However, trends of developments of the Eurasian Patent Organization and possible centralization of the regional protection of industrial property may testify that a Eurasian analogue of the Unified Patent Court would have a different institutional form.

The Socratic narration in Plato's Protagoras begins with the appearance of a young man. Early in the morning, a boy who had just learned that the sophist from Abdera is in town and who is yearning to meet him, goes to Socrates to request his accompanying. It is for this young man, and thanks to him, that Socrates, after a careful examination, decides to attend the gathering at Callias' house to converse with Protagoras. According to the narrative, the boy is the true catalyst for Socrates' attention and dedication to the sophist and, consequently, the real promoter and instigator of the dialogue. This paper mainly aims at shedding some light on the ethos and psychology of this young man named Hippocrates. Far from the picture often presented of him, merely of an innocent and helpless young man exposed at the dangers of the sophists’ teachings, this work stresses the boldness and excitement of a passionate and impulsive fellow whose irrationality is a potential threat not only for himself, but especially for those surrounding. In addition to the analysis of his ethos and psychology, the paper opens discussing to what extent and in what sense Hippocrates may be considered an associate of Socrates, and ends up speculating, relying on the Protagoras, about the possible causes that brought to the corruption of the souls of youth’s as such.

The views on the soul in the philosophical-theological thought of Au-relius Augustine (354–430 AD) hold a special place. When considering practically any of his teachings—whether it be his doctrine on the cosmos, time, memory, the relationship between free will and divine predestination, or his philosophy of history and pedagogy—we are inevitably compelled to take them into account or directly engage with them. His works are also associated with the so-called "psychologism" of Augustine, a concept high-lighted by numerous scholars delving into his truly vast creative heritage. The purpose of this paper is to explore the research devoted to the concepts of the soul (both individual and cosmic) in the works of Augustine or related to them. Additionally, it aims to identify works that address the issue of how Augustine's ideas about the soul were perceived in the early Middle Ages, using Cassiodorus [c. 487 – c. 578 AD] as an example. The studies, which encompass the aspects of Augustine’s psychological conception, are examined according to thematic principles, and divided into the following groups: (I) Studies dedicated to the exploration of Augustine’s cosmology, human existence, and soul (Among them: “Augustine’s Philosophy of Mind” by Gerard O’Daly [1987]; “Augustine: Ancient Thought Baptized” by J. Rist [1994]; “The World-Soul and Time in St. Augustine” [1983] and “Augus-tine’s Theory of Soul” [2003] by Roland Teske, and others). (II) Works demonstrating the influence of early teachings, traditions, and texts on Augustine (for example, “The Divine Sense: The Intellect in Patris-tic Theology” [2007] by Anna Williams and “Memory in Plotinus and Two Early Texts of St. Augustine” [1976] by Gerard O’Daly, among others). (III) Studies focused on the examination of individual works of Augustine with regard to their psychological aspects (Including: “An Analysis of Saint Augustine’s De immortalitate animae” [1980] and “The Fall of the Soul in Saint Augustine: A Quaestio Disputata” [1986] by Richard Penaskovic; “Augustine, Conf. IX, 10, 24” [1958] by John Taylor, and others). (IV) Papers indicating Cassiodorus’s reception and assimilation of Au-gustine’s teachings on the soul (e.g., e.g. “The Manuscripts of Cassiodorus’ De anima” [1959] by J.W. Halporn; “Cassiodoro e la grecità” [1986] by A. Garzya, “Il sottofondo culturale del De anima di Cassiodoro” [1995] by R. Masulo, etc.).

This paper examines the Talyshi people, an Iranian ethnic group divided by the Araxes River between Azerbaijan and Iran. The division, a result of the Russo-Persian War (1804-1813), placed the Talyshis within two distinct political and cultural paradigms. The northern Talyshis, under the successive rule of the Russian Empire, the Soviet Union and Azerbaijan, were confronted with a Turkish political and cultural orientation that contrasted with their Iranian linguistic and cultural heritage. This orientation led to significant shifts in identity, with the Talyshis becoming minorities within a Turkic-speaking, Turkish-oriented Azerbaijan. Southern Talyshis who remained in Iran experienced a more consistent cultural development within the Iranian paradigm, despite political changes. This study examines the impact of these divisions on Talyshi identity, language preservation and socio-cultural adaptation. It discusses the challenges of assimilation and cultural preservation faced by the Talyshis, their linguistic characteristics, and the revival of Talysh self-awareness and nationalism in the face of external pressures. The paper uses a comprehensive analysis of historical, linguistic and ethnographic data to provide insights into the resilience of Talysh identity amidst political and cultural change.

This paper examines the practice of female genital mutilation (FGM) among the Dawoodi Bohra community in Pakistan. FGM, a non-therapeutic alteration of the female genitalia, is examined through the lenses of religion, culture and health. The Dawoodi Bohra, predominantly based in Karachi, practice FGM as a religious and cultural rite, linking it to notions of purity and social acceptance. Despite global efforts to outlaw and eradicate FGM, it persists, underpinned by deeply held beliefs and the insular nature of the community. The physical and psychological effects of FGM are profound, leading to immediate and long-term complications such as severe pain, infection and psychological trauma. This paper discusses the impact of these practices on women’s health and rights, while critiquing the lack of an effective legal framework in Pakistan to combat FGM. In addressing this issue, the paper contributes to the broader discourse on gender-based violence and the rights of women and children in patriarchal societies.
