Filipendula ulmaria (L.) Maxim.) (Rosaceae) is a valuable medicinal, food plant, a fodder object for many wild animals. The species has a significant resource potential and is distinguished by high raw material reserves in many regions of Russia. The purpose of this study is to provide eco-coenotic and resource characteristics of the habitats of Filipendula ulmaria within the subzone of the southern taiga in the Kirov region. The study of phytocenoses with the participation of F. ulmaria was held during the 2019-2022 field seasons, on the territory of 3 administrative districts of the Kirov region. When performing geobotanical descriptions, the complete floral composition of communities was revealed, the projective coverage of each species and the general projective coverage were determined. Ecological parameters of plant communities were determined using phyto-indicative ecological scales of G. Ellenberg. The resource studies used generally accepted recommendations, terminology and methods for determining the production characteristics of herbaceous plants. According to the results of the survey, three groups of F. ulmaria habitat types were identified, belonging to floodplain wet meadows (I ecotype), deforestation in place of wet forests (II ecotype) and moist small-leaved forests (III ecotype). In the ecological-cenotic spectra of the studied communities, 7 ecological-cenotic groups were identified. The majority of the studied phytocenoses with F. ulmaria (I, II ecotype) are characterized by the predominance of representatives of the meadow and meadow-fringe group (from 56,0 to 64,8% of the total number of species), the boreal group only in forest habitats (III ecotype) (53,8%). The spectrum of life forms is dominated by herbaceous polycarpics (57,5-85,0%). The presence of trees in the flora of meadows indicates the possible beginning of restoration successions - the formation of forests on the site of meadows. It was found that the strongest influence of environmental factors on the distribution of the species is exerted by soil acidity (90%) and soil moisture (10%), which determine 100% of the total variability. The highest indicators of the specific raw phytomass of F. ulmaria are observed in the conditions of meadow communities.
The article is devoted to studying the dynamics of formation and development of gully landforms on the territory of the Elanka settlement of the Khangalasskiy District in Central Yakutia, explaining the mechanisms of formation and growth of gully landforms in permafrost landscapes and the reasons for activation of thermoerosion processes on the territory of the Lena River floodplain terrace. Physical and geographical characteristics of the area and a brief historical note about the researched locality are given. The results of observations and research carried out on the territory of the settlement during the period from 2019 to 2021 are presented, with a description of existing regularities between the distribution conditions of different morphometric data gully landforms. A comparison of the size values of the study objects for the entire period is given. As a result, a dynamic increase in the size of gully landforms is registered, the further development of which in subsequent years poses a threat to human economic activity in the territory of the settlement of the study, and also in the territory of other settlements that are located on the floodplain terrace of the Lena River with similar physical and geographical conditions. Examples of development of gully systems in other settlements of Khangalassky District are given. A sharp increase in the amount of atmospheric precipitation on the territory of Central Yakutia and a general increase in surface air temperature as one of the causes of the gully dissection of the relief of the Lena river floodplain terrace is considered. It is assumed that similar examples of gully dissection of territories take place in other settlements located on the Lena River floodplain terrace, in which no studies of the relief have been conducted earlier. It is recommended to carry out similar studies of relief disturbance in the above-mentioned settlements.

A solar eclipse affects the Earth's upper atmosphere. The eclipse time can be calculated in advance, which allows us to prepare for experiments. Dynamic processes during each specific eclipse depend on the heliogeophysical environment. VLF radio waves can propagate thousands of kilometers in the Earth-ionosphere waveguide. The location of the VLF radio paths determines the space for monitoring the lower ionosphere (as a part of the upper atmosphere). We applied a method of studying the amplitude variation of VLF radio signals from DHO (23.4 kHz, 53.08° N, 7.62° E) and JXN (16.4 kHz, 66.97° N, 13.87° E) transmitters received in Yakutsk. The most part of these radio paths is located along the Arctic territory of Eurasia. The diurnal VLF amplitude variations of the DHO и JXN signals from June 7 to 13 are explained by the solar ionizing flux variation, the higher-order modes interference during the passage of the rising and setting terminators along the elements of the radio paths, and the transmitters operating mode. During the solar eclipse of June 10, 2021, the minimum average ratio value of the open part of the solar disk area to the full disk area was 0.532 (11:39:18 UTC) and 0.411 (11:33:00 UTC) along the DHO - Yakutsk and JXN - Yakutsk radio paths, respectively. The eclipse effect appeared as an amplitude increase at the maximum of 1.62 dB (11:39:18 UTC) and 1.4 dB (11:26:42 UTC) for the DHO and JXN signals, respectively. Furthermore, our data provide the low VLF receivers manufacturing costs and the ability to cover large areas make the VLF registration a convenient tool for sounding the lower ionosphere over the hard-to-reach and sparsely populated areas.
The number of children with various kidney pathologies has increased significantly in recent years. The reason for this may be an unfavorable environmental situation, complications of infectious diseases, racial and genetic predispositions, etc. It is known that hematuria is one of the main symptoms of a disease of the urinary system. A large number of factors can cause hematuria, among which the most common are: mechanical injuries, microbial inflammatory processes, immunocomplex nephritis, renal vasculitis, etc. This paper deals with glomerulonephritis of renal origin, in the differential diagnosis of which a kidney biopsy is often used. Kidney biopsy is the primary method of differentiating renal disease, and although this procedure is considered safe and in most cases proceeds without critical complications, the risk of complications still remains. The list of risks arising during a kidney biopsy can include: the formation of a hematoma, infection, arteriovenous fistula as a result of needle injury to the walls of large vessels. All of the above can lead to serious complications or even death. In this regard, there is a need for the formation of new, modern and non-invasive differential diagnostic methods. Given the fact that in clinical medicine there is a growing interest in new methods of diagnosis, treatment and prevention, which in particular is due to the emergence of new methods and devices that allow the study of qualitative and quantitative characteristics of biological samples at the molecular and nano levels, in this paper we investigated dry blood smears of children with hematuria syndrome with diagnoses: acute glomerulonephritis, chronic glomerulonephritis and IgA nephropathy. The smears were applied to a slide and examined by infrared spectrometry. Maxima of characteristic bands were selected for the study and maximums of the corresponding peaks of the spectrum of children with hematuria syndrome and the control group were compared, statistical processing of data using Student's t-test was carried out. As a result, a statistically significant difference in the maximum peaks between the samples studied and those of the control group was revealed. Based on the data obtained, we suppose that it is possible to create a new, noninvasive method of differential diagnostics of renal diseases.

The article is dedicated to the study of the phenomenon of hashtaging. The importance of the study is determined by the need to comprehend the main social and political processes presented in the texts of media discourse, in particular in the texts of social networks, in order to identify key events at the present stage of development through linguistic analysis. The novelty of the research is seen in the fact that the hashtaging process is considered as a new linguistic phenomenon that can determine political, economic and social processes. The purpose of the article is to study the protest movements on the example of actions in social networks during the Arab Spring. The main research method is the case method. The main objectives of the study include the process of identifying the topic of hashtags and determining the basic principles of word formation in the process of protest movements on social platforms. The results of the research include the identification of six key themes of hashtagged lexemes (date of event, country of event, venue, call for union, topic of protest) that cover protests, and language compression, which is often used in the hashtagging process. The prospects of the research are determined by the fact that the process of deciphering hashtags by identified patterns becomes possible for use in other protest movements around the world. Important attention is paid to deciphering a certain number of hashtags in order to understand the extralinguistic situation that they represent. It is highlighted that the principle of saving speech efforts is widespread on the social platforms. Through statistical analysis, the ideas regarding the linguistic character of these units are confirmed: the process of reduction acts as a formative process in their creation; the usage of abbreviated hashtags in political texts seems to be a frequent and natural principle in modern virtual discourse.
The subject of research in this article is the motive, figurative, ideological intersections of the trajectories of A. P Chekhov's story “A Misfortune” and the novel by L. N. Tolstoy “Anna Karenina”. The comparison of these works is extremely relevant, since its results can correct the idea of the hero of the love collision. In addition to “Anna Karenina”, in “A Misfortune” one can find references to “Eugene Onegin” by A. S. Pushkin and “Rudin” by I. S. Turgenev. The purpose of this article is to determine the trajectory of the development of images and motifs of Pushkin's, Turgenev's and Tolstoy's prose, inscribed in the “dacha topos” of A. P. Chekhov's story “A Misfortune”. The objectives of our research include determining the specifics of the writer's attitude to literary tradition, analyzing its use and interpretation in Chekhov's story, which becomes possible with methods of comparative and motivic analysis involving elements of structural analysis. The images and motives unfolded in the plots of Chekhov's pretexts are deformed and inverted in “A Misfortune”. Chekhov's semantics of boredom and monotony are connected with the topos of the railway, where the heroes of “A Misfortune” meet, depriving this meeting of a fateful potency. The dacha topos constantly mentioned in the text of the story, in the entourage of which the characters' relationships develop in accordance with the dacha chronotope, introduces an additional depoetizing meaning. The description of the characters of “A Misfortune” also contains an obvious reductive irony, emphasizing their spiritual inadequacy. The focus is also on questions about the author's attitude to the characters of “A Misfortune” and the ambiguous semantics of the title of Chekhov's story. It seems relevant and promising to further study the creative dialogue between Chekhov and his predecessor writers, which allows us to take a fresh look at the features of the literary anthropology of Chekhov's work.
The relevance of the scientific research and its results is due to the currently unresolved problem of studying forgotten semantic features in the content of the vocabulary of the Evenki language. It is considered to be one of the most important tasks for modern Evenki linguistics. This research contributes to the solution of this problem. The study of the conceptosphere of the Evenki language makes it possible to reconstruct the linguistic picture of the world of the Tungus, and to restore some individual mental units of thinking of nomadic hunters and reindeer herders. The article is devoted to the linguistic and cultural research of the conceptualization of a reindeer herder in the linguistic picture of the Evenki world. The aim of the research is the analysis of conceptual, figurative and value components of the mental formation. The method of linguocultural description of the concept is applied in the study. The studied mental formation is a basic ethno-cultural fragment of the linguistic picture of the world of the Evenks, constituting the national and cultural uniqueness of the ethnos. The concept "orochii / reindeer herder" is a structural component of the mental formation "oron / reindeer". The presence of the basic lexeme-representative of the concept under consideration in all the Tungusic languages may indicate its antiquity. The analysis of dictionary articles, folklore, art and authentic texts showed the presence of the following semantic features in the concept under study: a) a pathfinder, b) a nomad, c) an excellent reindeer rider, d) a guide, e) a watchman, a guardian for reindeer, f) a person with reindeer, g) a hunter. The reindeer herder is a typically recognizable image of the Tungus culture. It contributes to the preservation of the Evenki language and culture. The loss of reindeer husbandry as a traditional type of economy of the Tungus will contribute to the deactualization of the concept under study, which will entail the loss of a large part of the vocabulary of the Evenki language. The prospect of further research could be the study of the conceptosphere of the children of reindeer herders, which will show the level of the young generation's mastery of reindeer terminology and the presence or absence of certain cognitive features in the composition of the concept.
The specifics of comparative constructions of the Tuvan language are revealed by the example of the functioning of the operator dömei. Such constructions may include an auxiliary element - an operator, or a comparison module that marks the fact of comparing objects, and introduces additional shades of meaning into the construction (confidence, uncertainty, doubts, assumptions). A descriptive method was used to systematize and generalize the results of observations. The scientific novelty of the study lies in the fact that for the first time lexical units, conditioned by some external and internal conditions, are considered as comparative. To external conditions, we refer: cases, particles. Substantive components denoting representatives of fauna, flora, as well as natural phenomena are most often used as an object of comparison. The structure of the comparative construction in our work is given by the following formula: A + C + β + B, where A is the subject of speech (what is being compared), B is the input image (what is being compared with), C is the module (the attribute by which it is being compared), в is the operator (the formal indicator of comparison). As an indicator of comparison, the comparative dömei ‘similar’ is used, denoting similarity, likeness, resemblance and controlling the ablative case -bile (structural diagram: NNOM NINSTR dömei); and less often the dative case = ga (structural diagram: NNOM NDAT dömei), and structures with particles -la, -dyr, - il are also considered. As a result of the conducted research, we come to the following conclusions: Comparison is a mental ethnical-specific formation reflecting the totality of knowledge about this object expressed by various linguistic means. The comparison that each ethnic group possesses always finds its expression in language at all its levels. As a research perspective, we believe that in other languages it is possible to find not only similar Tuvan linguistic means of verbalization of the concept of comparison, but also to replenish this repertory with other comparatives.
