The paper presents a systematic review of the Poaceae Branh. family in the collection of the Herbarium of the North-Eastern Federal University (NEFU). The scientific fund of the herbarium contains 682 specimens from the Poaceae. The collections starting from 1953 are presented. The largest number of collections falls on 1955-1980. The main collectors are S. Z. Scriabin, A. A. Permyakova, Yu. V. Rykova, T. F. Galaktionova, V. I. Perfileva, V. M. Usanova. The collection of the NEFU herbarium includes 123 species from 36 genera of the Poaceae family, of which 8 species are rare and endemic: Koeleria sckrjabinii Karav. et Tzvel., Elytrigia villosa (Drob.) Tzvel., Festuca pseudosulcata Drob., Helictotrichon krylovii (Pavl.) Henrard, Hyalopoa lanatiflora (Roshev.) Tzvelev s.str., Hyalopoa lanatiflora subsp. momica (Tzvel.) Tzvel., Koeleria sckrjabinii Karav.ue Tzvelev, Melica nutans L. Inventory, systematization, digitization of material was carried out to create an electronic database - the digital herbarium of NEFU. Also, for the digital herbarium, morphological descriptions, information on the features of the ecology and distribution of species, a list of scientific works of researchers on the study of their biomorphology, ontogeny and the structure of coenopopulations in the Republic of Sakha (Yakutia) have been prepared. Author's photographs of plants in nature, photographs of taxonomically significant morphological characters of species have been prepared. The digital herbarium of NEFU will provide free and quick access to the collection of plants not only for students and university staff, but also for everyone who wants to get acquainted with the stored herbarium specimens. In the future, it is planned to fill in the database on all collections of the scientific herbarium.

Within the territory of Siberia, the sterlet (Acipenser ruthenus L., 1758) is distributed in the basins of the Ob and Yenisei. In Lake Baikal and its tributaries, except for the Angara, as well as in the rivers of Eastern Siberia, it is not found, which is closely related to the process of formation of the lake-river network in Northern Asia and its settlement by ichthyofauna. In the Ob River the sterlet lives both in the main riverbed and in many of its tributaries, as well as in the Irtysh and Yamal rivers. In the lower reaches of the Ob River and in the southern part of the Ob Bay, the sterlet is not numerous, and in the northern part of the bay it is rare. In the rivers of Siberia this species is the object of commercial and amateur fishing, usually under licenses. This paper presents the results of study the content of metals (Mn, Fe, Si, Zn, Cd, Co, Hg and Pb) in muscle tissue (from the lateral part of the trunk under the dorsal fin), in the liver, kidneys, spleen, gills, swim bladder and vertebrae, taken from 35 of mature individuals of sterlet caught in June 2020 in the middle reaches of the Ob River near the village Melnikovo (Shegarka - 950 km on the 1987 route). For comparison we also used the published results of similar studies conducted in 2013, 2015 and 2018. Chemical analysis of the samples was carried out in the laboratory of the Analytical Center of the Institute of Geology and Mineralogy SB RAS by atomic absorption spectrometry. As a result of the conducted studies, differences in the concentration of each metal were revealed both in different organs of fish of the same sample, and when comparing this indicator between samples of different years. In general terms, the nature of the accumulation of metals in the body of the sterlet is like that in other representatives of the family of sturgeon (Acipenseridae) and bony fish (Osteichthyes). In the muscle tissue of the studied fish individuals, the concentration of metals did not exceed the standards accepted in Russia. The relevance of the work is connected, according to the authors, with some features of the biochemistry and physiology of sturgeon (Acipenseriformes), including their response to water pollution, as well as in connection with the above-mentioned value of sturgeon as objects of fishing and aquaculture.

The Raman spectra of carbon nanoribbons are calculated using the density functional theory in the local density approximation. It was found that in all the nanoribbons considered by us, there are three active modes: the radially breathing RBLM mode in the frequency range 346-474 cm-1, a localized mode in the frequency range 1449-1462 cm-1, and a graphene-like mode at a frequency of about 1650 cm-1. one. These active modes can be useful for identifying various nanoribbons in Raman experiments. Theoretical calculations were compared with experimental data.

The lexicographic description of the birds’ names in the Hebrew language is a relevant topic for Hebraic studies. Many of these terms occur once or more in the Bible, and thus do not have a clear zoological identification. When forming the lexical composition of modern Hebrew, these terms were given specific scientific meanings based on a variety of arguments, including the nature of their use in various post - Biblical text corpora. In this article, we look at the names of birds, in Biblical, medieval and modern Hebrew. The purpose of this article is to explore the names of birds that are mentioned in the Bible, and their semantic and functional evolution in Rabbinic, medieval, and modern language. To achieve this goal, a number of tasks were solved: the isolation of the studied lexemes from the general set of faunal terminology. For this study, we have taken the terms for the bird that are mentioned in the Bible. A study of them uses in Hebrew text corpora in Rabbinic, medieval, and modern literatures. Consideration of relevant terms using a method that includes contextual, semantic, and linguistic aspects. The study of the names of birds in different epochs of the development of the Hebrew language gives an idea of the problems and methods of semantic description of the vocabulary of the ancient written language and its development in its modern written and spoken forms. The results of the study claim that the names of birds in the Hebrew language is dynamic, since most bird names in the Biblical language do not have an exact meaning due to a disagreement between ancient and medieval commentaries or a matching passage between the Hebrew and ancient Greek Bibles. As a result, many of them remain in question until now. In modern Hebrew, many of the biblical names of birds have changed their meanings over time and today they differ from the original language.

The creative legacy of the poet and prose writer Vasily Golderov still remains unappreciated. Among his poetic works, the most recognized one is “The Unforgettable Tenth Grade” poem only, which has become a popular song; researchers of his prose limit themselves to remarks on the lyrical nature of his stories. Therefore, basing on the material of the writer's short prose, the purpose of this article, is to reveal his mastery as an artist of the word. To achieve the goal, we set the following tasks: to consider the role of the tradition and to define the innovation in the Vasily Golderov’s artistic world, in particular, to analyze the genre system, plot-compositional structure, principles of narration, and the methods of psychologism in his stories. However focused on the phenomenon of man, they also reflect the events and contradictions of the era. Thus, in a number of stories, the echoes of the Great Patriotic War are present, though the war theme is transformed; rather than being concrete historical, it becomes a historical-moral one, also serving as a source of national history and memory, as well as a measure of social and human values. The author also could not but reflect on the topic of political repressions and the relapse of the command-administrative style of leadership. As for the Vasily Golderov’s character system, his principle of creating the image of a person is based not on social, but rather personal typification. That means that his characters do not fit into a certain social “case” and are drawn as humans. At the same time, two trends clearly show through: on the one hand, the polarization, and on the other, individualization of characters. As a result of the study, it was established that the Vasily Golderov’s small prose, along with the influence of Yakut writers, primarily A. Fedorov’s, was also shaped by the Russian classical literature, in particular Anton Chekhov’s stories. It is seen in the use of such techniques as "open finals", omission and subtext. The writer’s poetic arsenal has a whole system of psychologism techniques, from the portraitism, artistic detail, accompanying landscape, and phytoimages to the dream poetics and intertext. In addition, there is introduced the new intragenre gradation of small prose by the plot-composition structure, identifying such varieties as the story-reminnisence, story-revelation, story-discovery, story-insight, and the story-anticipation. The study uses the principles of the comparative historical and typological methods of analyzing literary material.

The article focuses on the code switching mechanism in a bi-cultural anglophone literary text. The problem of the manifestation of this strategy in speech is currently relevant, since with the process of globalization and the manifestation of interethnic contacts, the mixture of languages and cultures take place, and therefore, the interest to the problems of bi - and multilingualism is increasing. The purpose of the study is to consider the phenomenon of code switching as one of the categories of language mixing, their specific features and implementation in the works of Ch. Bronte (the English-speaking bi-cultural writer-translinguist). The use of textual, pragmatic, functional, and stylistic research methods, including the method of discursive analysis, shows that the multilingual competence of a translingual writer is realized through this language strategy. The analysis shows that the multilingual competence of a translingual writer is realized by means of this language strategy. In this regard, code switches are used by the author intentionally as a sociolinguistic means to achieve a certain goal, as a variable form of discourse, a full-fledged linguistic phenomenon, stylistic or expressive device and to contribute an element of colloquial style into the narrative to provide emphasis and expression. It states that code switches transmit emotional categories in situations of increased emotional context to represent strong emotions in the text, to implement a pragmatic function, and reveal the linguistic and literary worldview of a translingual writer. The pragmatic feature of code switching is a conscious action. Thus, a certain goal is pursued when switching to another language, which contributes to the implementation of a certain communication, demonstrating one's attitude to various components of the speech act, for example, to the addressee, the message, the referent. The ability of an active language mixing of a translingual writer demonstrates a high degree of language proficiency and a certain communication bi-culture of a person, which makes communication the most comfortable and ensures mutual understanding between the interlocutors. Translingual writers distribute the use of the languages they speak, depending on the conditions of communication, the method of switching the code is introduced by the translingual author to impart the text authenticity, create color atmosphere, the impression of reading, etc. The authors of bicultural literary texts, as a rule, have time to choose the language form of expression, so they strive to convey their thoughts and feelings to the reader in the most effective form, attract attention and deliver aesthetic pleasure.

The relevance of the article is determined by the need to trace the evolution of Lyudmila Ulitskaya's creative search in connection with the publication of short stories collection "About the Body of the Soul. New Stories" (2019). The authors of the article rely on the experience of the study of women's prose [1], part of which are the works of the writer. The analytical body of the article includes the stories "The Dragon and the Phoenix", "The Serpentine" and "The Man in the Mountain Landscape", which have not yet received the assessment of literary critics. Problematically, the article is aimed at revealing the features of the narrative structure of the latest Russian prose. Observations of the poetics peculiarities of Lyudmila Ulitskaya's prose, the expansion of artistic means and techniques, as well as the natural deepening of the philosophical content in the literary text allow us to solve the following tasks on the methodological basis of comparative analysis: 1. To summarize the artistic experience of L. Ulitskaya in the aspect of the continuity of the tradition of realistic and romantic world literature on the path of aesthetic renewal of her small prose.To explore the typology of characters in connection with the changing spiritual values of the 21st century. 2. To consider in the narrative space of the stories the author's transformation of the names, their semantic nature, as well as to identify the metaphorical content filled with the artistic discovery of new realities. The current difficult situation in the relationship between the writer and the reader, the author and the critic optimizes the task of literary research of a new literary text that is functional for the perception and objective assessment of the writer's work in the context of genre and style searches for new prose in Russia. The result of the analysis of the new stories of L. Ulitskaya was the conditional division of the writer's work into two stages, the first of which is entirely connected with the formation of women's prose in Russian literature of the 20th century, the second is characterized by a kind of going beyond the gender space and is filled with the philosophical meaning of the hero's ascent from everyday life to Being. The final observations can be used as a reference point in the study of prose of the 21st century. The material is of practical importance when creating online lectures, in multimedia projects.

The article is an attempt to apply some methods of cognitive text modeling in the study of the genre of public speaking. The aim of the work is to highlight and linguistically analyze the world of the future and the world of the past, which the author presents in his speech. Concerning the linguistic analysis of the text, A. M. Mukhin proposes to focus on language levels, which make it possible to identify phonetic (phonological), morphological, grammatical, syntactic and lexical features of a speech utterance. This approach provides a holistic analysis of the plan of expression and the plan of the content of the text, however, due to the concise character of the study, this work focuses on the grammatical and lexical levels of the language. For this analysis, the entire inaugural speech of the President D. Trump was chosen as a super-phrasal unity. To determine the "contours" of the two opposed worlds we used the approach of D. McIntyre, who proposed to distinguish five main deictic categories: place deixis, temporal deixis, person deixis, social deixis, empathic deixis. A model or image of the world is a sensory image of reality, analytically processed through speech. That is why the article provides a linguistic analysis of the means of building this world in conjunction with deictic categories that "outline" more or less clear boundaries of the models of those worlds that the author is trying to oppose. The work is interdisciplinary, the relevance of this study is associated not only with the current political situation (namely, with the election of the new US president), but also with the use of the categories of “entry” into the text worlds in the study of the genre of public speaking. This work can be continued and deepened, since research methods of cognitive world modeling (category of voice, perspective, point of view, etc.) can be successfully applied in the study of texts of public speeches. The proof of this statement is this article.

The article connects two of the most relevant areas of modern literary studies - the literature of the Russian diaspora and modern Yesenin studies. In addition to the publications of the American Russian-language periodicals introduced into scientific circulation by N. I. Shubnikova-Guseva, N. M. Solobay, M. V. Skorokhodov and E. Yu. Kolomiytseva, it provides an analytical review of the materials identified by the author. These materials, which have never before come in the field of view of the researchers, characterize the way Russian emigration the United States perceived S. A. Yesenin's creativity during the period of the growth of interest in him in 1950-1951 associated with the 25th anniversary of his death and with critical reviews of his work and personality written by I. A. Bunin. As a source of information, we consider the epistolary heritage of the representatives of the creative part of the emigration associated with Yesenin by friendship and cooperation: the poet, journalist, publisher V. M. Levin (1892-1953) and his brother, the artist and poet I. M. Levin (1894-1979), as well as their manuscripts and articles. Among them, of particular interest is the little-known article by V. M. Levin "Two Poets", written in response to the harsh anti-Yesenin attacks of I. A. Bunin, and published in the literary and artistic magazine "Delo". Based on the analysis of the Levin brothers' memoirs, it is noted that they are closely related to Yesenin in their spiritual search and, as a result, they reflect Yesenin's Christian spirituality in their work. Attention is drawn to the creative parallels in the works of Yesenin and the Levin brothers, and the assumption about the creative mutual influence of S. A. Yesenin and V. M. Levin is substantiated. Based on the correspondence of the Levin brothers, the situation that developed among the Russian emigration in the United States on the eve of the 25th anniversary of the death of S. A. Yesenin is restored, and the conclusion is made about the cultural and historical significance of the newly identified materials and the need for their further research.

An attempt to form a methodology for analyzing the Yakut city text based on the literary material of the Yakut prose of the twentieth century, which is already original due to the authenticity and content of the object of research - the northernmost, farthest and coldest city of Yakutsk - is included in one of the most pressing problems of Russian literary studies in recent years - the study of local text. Conceptually this work relies on the scientific views of local texts, by their very nature refers to the much broader city, suggesting, in our opinion, in addition to the city of the text include: alas text, and the liminal world of the road, creating art model space, complementary and adjacent to each other in a single Yakut text. Тhe determination of the geo-cultural landscape of Yakutsk segment within which most clearly reveals the unique quality of domestic peace. The relevance of the article is dictated by the need to study an unexplored topic in the Yakut science - the local urban text. The scientific novelty of the article is obvious: the understanding of the city as a semantic structure, which is manifested in the constancy of images, universals that have a cultural-historical, mental community and are united in a single artistic system, was not undertaken as an independent study. In the context of this article, the category of inversion also receives a special interpretation that claims to be new, which justifies the artistic organization of the entire Yakut world. The study of the geopoetic landscape of Yakutsk, which to this day has not received a detailed elaboration in Yakut literary criticism, is argued by the idea of the city as a structure consisting of several models of the Yakut urban text: sales of Yakutsk in the works of writers of the early century; Happy Yakutsk in the 1950-1980's.; of the city-prison in the late 90s. The results of the research undertaken in this article can be used in the development of problems of the artistic landscape, which are becoming the most relevant in recent times in Russian science.

The relevance of the work relates to interest in origin and interpretation of medical terminology as the language of professional communication, and the aspect of evolution and transformation of communication in medical activity. The problem involves the reconstruction and description of medicine’s sublanguage, inspired by dialects, of changeable professional language system. As a result, it is represented the influence of V. I. Dahl's lexicographic work on the formation of Russian-language scientific terminology and modern discourse of professional medical vocabulary. Including methods of linguistic research, such as structural-semantic, cognitive, conceptual analysis of lexical units, statistical analysis of the frequency, it is represented more than 150 lexemes with the concept "disease". Scientific originality consists of complex analyze of the most productive models of word formation in etymological and structural features. As a practical meaning of study, it is indicated the progress of future research, devoted the problems of dialectal formations with the concept "disease"; restoration the chronology of professional communication language; systematization and differentiation of constructions by dialectal origin, existed as terminological "bilingualism", as outdated terminology, or as the only part of localized dialects. As the final conclusions, it is represented the most useable constructions of procedural and temporal meaning, biomorphisms, coloratives, geomorphisms, also it is indicated a weak differentiation of medical dialectal vocabulary, the most productive verbal and nominative derivational models, the predominance of monolexemes over two-component constructions. The main semantic meanings characterize the concept of "disease", the differentiation of dialectic words is indicated in accordance with the area of distribution, the features of interpretation and nomination the medical vocabulary determined as refraction of evolutional professional language system of communication in historical age.
