“Russia, Rossia, Rus, Kolomna: Province”: Conceptualization of Space in B. Pylnyak’s Novel “Volga Flows into Caspian Sea”

The principles of structuring and methods of objectification of the spatial continuum in B. Pylnyak’s novel “The Volga flows into the Caspian Sea” are investigated. Particular attention is focused on the lexical representation of space as a basic category of the author’s language picture of the world. The novelty of the research consists in the identification, systematization and description of linguistic material, which allows to determine individual author’s features in the creation of the spatial continuum of B. Pylniak’s novel. The relevance of the article is due to addressing the problem of linguistic expression of world-modeling universals in a literary text. The article uses methods of semantic and linguistic stylistic analysis, comparison and description of language units. It helps us to identify and consider the means of lexical representation of the spatial model created in the novel “Volga Falls into Caspian Sea”, which is characterized by kaleidoscopicity, dynamism and the combination of different spatial planes. During the research, the author comes to conclusions containing the characteristics of the main types of space in B. Pylniak’s novel, taking into account the individual features of the author’s world modeling, as well as the substantiation of the revealed linguistic parameters of the writer’s idiostyle

Means of Lexical Representation of Spatial Continuum in Early Stories of I. A. Bunin

The question of ways of creating a spatial continuum in the early stories of I. A. Bunin “On the wrong side”, “On the farm” and “On the Donets”, united by a single principle of nomination and included in the first book of the writer’s prose “To the end of the world” (1897) is considered in the article. The semantics of the title actualizes the spatial component of the author’s linguistic picture of the world, which determined the path of linguistic and stylistic analysis of the linguistic material of stories. The authors pay special attention to the means of lexical representation of space as one of the basic linguo-cognitive categories. The novelty of the research lies in the fact that the language material has been identified, systematized and described, which makes it possible to determine the individual author's characteristics in the creation of the spatial continuum of I. A. Bunin’s early stories. The relevance of the study is due to the appeal to the problems of cognitive linguistics. On the basis of statistical, descriptive and linguo-cognitive methods of analysis, the authors identify and describe the means of lexical representation of the spatial model created in the stories of I. A. Bunin, which is characterized by a clear structuredness and individuality of the author’s approach. In the course of the study, the authors come to conclusions that make it possible to characterize the features of the construction of space in the early stories of the writer, taking into account the individual characteristics of the author's world modeling, and also to analyze the linguistic parameters of the idiostyle of I. A. Bunin

Verbs of Thought as a Way of Characterizing Hero-Intellectual in Short Prose of A. P. Chekhov and A. I. Kuprin

The verbs of thought and their role in the characterization of the linguistic personality of the hero-intellectual based on the stories of A. P. Chekhov “My Life” and A. I. Kuprin “Moloch” is examined in the article. It is noted that this study will allow a comparative analysis of the characters in order to identify the typical and individual in their ideas about the world, in the system of their views on the world, in the direction of their thought process. The relevance of the work is determined by addressing the problem of describing a linguistic personality in a literary text. The novelty of the article lies in the study of variations in the representation of the model personality of the hero-intellectual in late 19th century Russian prose. The article uses methods of semantic and linguo-stylistic analysis, comparison and description of language units. The conclusions substantiate that in the presence of distinctive features in the mental activity of the characters, as well as in the principles of constructing their speech strategies, there are common, typological properties, which is due to their belonging to the same social stratum and cultural and historical era. The authors believe that these characters can be attributed to the model language personality of a Russian intellectual at the turn of the 19th—20th centuries

Motive of “Liberated Soul” as a World-Modeling Universal in Lyrics of S. Parnok

The article is devoted to the analysis of the motif-figurative paradigm of the Silver Age poetess S. Parnok’s lyrics. The author’s attention is focused on the ways of stylistic representation of the world-modeling universals of the poetic world of S. Parnok, an important place among which belongs to the motive of the “liberated soul”. It is a starting point in the construction of the author’s picture of the world, in the center of which the path of the lyrical heroine to her soul underlies: its comprehension, acceptance of its contradictions and embodiment in a creative act. The novelty of the study is in the analysis of S. Parnok’s lyrics as an integral compositional and stylistic unity, structured by poetic leitmotifs. The relevance of the article is due to the appeal to the problematic field of research on poetic style. The authors made an attempt to deepen and expand scientific ideas about the stylistic phenomenon of women’s poetry of the Silver Age based on the analysis of S. Parnok’s lyrics. The conclusions of the study substantiate the semantic load and the functional role of the “liberated soul” motif in structuring the author’s poetic picture of the world. It is shown that the leading methods of its representation are metaphorization, epithets, including synesthetic ones, antithesis, oxymoron, at the level of syntactic organization — gradation, enjambment technique

Determination of tomato quality with hyperspectral imaging

Received: February 1st, 2023 ; Accepted: July 14th, 2023 ; Published: October 13th, 2023 ; Correspondence: [email protected] (Solanum lycopersicum L.) are a widely used vegetable in the human diet throughout the year, both fresh and in various processed products. Tomatoes contain compounds important to human health and are an important source of vitamins, antioxidants, and mineral elements. Performing biochemical analyses is an expensive, environmentally unfriendly and time-consuming process; therefore, a way to determine the biochemical composition of tomatoes using non-destructive methods is being sought. The study includes 45 varieties of tomatoes with different colors - red, pink, orange, brown, yellow, and bicolor tomato fruits. The content of dry matter, soluble dry matter, titratable acidity, lycopene, β-carotene, total phenol, and flavonoids was determined by standard biochemical procedure. Reflectance spectrums of tomato fruits were obtained with Remote Sensing Portable Spectroradiometer RS-3500 (Ltd. Spectral Evolution, Haverhill, MA, USA) at the wavelength 350–2,500 nm with a 1 nm interval. In order to determine the content of various biochemical parameters in tomatoes, the vegetation indices found in the literature were used, and new ones were developed. The research demonstrated that the developed vegetative indices allow to detect lycopene and β-carotene content non-destructively. For the determination of the dry matter, soluble solids and phenolic content, indices designed for detecting water content can be used, but their correlation coefficients with chemical methods are moderately high - 0.65, 0.56 and 0.57, respectively. It was found that the best correlation between biochemically detected parameters and vegetation indices is for lycopene > β-carotene > dry matter> total phenols = titratable acidity ≥ soluble solids > taste index > flavonoids

Possibilities of cucumber powdery mildew detection by visible and near-infrared spectroscopy

Received: July 16th, 2021 ; Accepted: November 6th, 2021 ; Published: February 1st, 2022 ; Correspondence: [email protected] are one of the most demanded and widely grown greenhouse vegetables. Important factors that influence quality and quantity of yield are diseases. Powdery mildew (caused by Podosphaera xanthii and/or Golovinomyces cichoracearum), is one of the most harmful cucumber diseases. Early detection of mildew via non-destructive methods can optimize schemes of fungicide application. The study aimed to find regularities in the reflected light spectra, indices described in the literature, and severity of mildew. Plants were grown in the polycarbonate greenhouse under artificial lighting in a 16 h photoperiod with PAR at the tips of plants 200 ± 30 µmol m-2 s-1. Leaf reflection spectra were obtained using spectroradiometer RS-3500 (Ltd. Spectral Evolution). Spectral range 350–2,500 nm, bandwidth 1 nm. The severity of cucumber mildew was evaluated using 10 point scale (0- no symptoms, … 9 - the plant is dead). The vegetation indices found in the literature have been calculated. The obtained results show that the calculated indices have different sensitivities. The strongest correlation between the degree of cucumbers infection with powdery mildew and the light reflectance spectrum was found in the green range of visible light around 550 nm. Disease-Water Stress Index-2 (DSWI-2), Structure Intensive Pigment Index (SIPI), and Normalized Difference Vegetation Index (NDVI) are the most suitable indices for determining powdery mildew in cucumbers. New indices for detection of powdery mildew have been created. None of the studied indices allows determining the powdery mildew at the early stages of disease development when powdery mildew severity is below 10%

Relationship between oral health status and cognitive functions

With global increases in the aging population, the number of patients with cognitive decline is greatly increasing, which has become a big social problem. The studies conducted previously suggest the possible relationship between oral health and cognitive status. It is well-known, that the oral cavity is an important component not only the maxillofacial region, but also acontributor of general health. In this article, we highlight the relationship among dentoalveolar system and the cognitive functions. Studies using functional magnetic resonance imaging revealed that during mastication there is activation of somatosensory cortical areas, the supplementary motor area, insula, and other areas including the striatum, thalamus and cerebellum. According to the results of the сlinical studies, patients with dementia have demonstrated poor oral hygiene, greater incidence of periodontal diseases and tooth loss. Accumulating evidence suggests that cognitive decline may be associated with masticatory dysfunction. Masticatory dysfunction, as an umbrella term, refers to a debilitating condition in which normal masticatory function is compromised due to structural factors (e.g., tooth loss) or functional factors (e.g., weaker biting force or poorer masticatory performance). The presented data support the hypothesis that there is a possible relationship between mastication, oral health status and cognitive functions, therefore maintenance and adequate restoration of the whole masticatory system are important for the prevention of cognitive decline. This problem requires further clinical interdisciplinary studies, assessing cognitive abilities and oral health

Antioxidative vs cytotoxic activities of organotin complexes bearing 2,6-di-tert-butylphenol moieties

Copyright © 2018 John Wiley & Sons, Ltd. Two series of organotin(IV) complexes with Sn–S bonds on the base of 2,6-di-tert-butyl-4-mercaptophenol (L1SH) of formulae Me2Sn(L1S)2 (1); Et2Sn(L1S)2 (2); Bu2Sn(L1S)2 (3); Ph2Sn(L1S)2 (4); (L1)2Sn(L1S)2 (5); Me3Sn(L1S) (6); Ph3Sn(L1S) (7) (L1 = 3,5-di-tert-butyl-4-hydroxyphenyl), together with the new ones [Me3SnCl(L2)] (8), [Me2SnCl2(L2)2] (9) (L2 = 2-(N-3′,5′-di-tert-butyl-4′-hydroxyphenyl)-iminomethylphenol) were used to study their antioxidant and cytotoxic activity. Novel complexes 8, 9 of MenSnCl4 − n (n = 3, 2) with Schiff base were synthesized and characterized by 1H, 13C NMR, IR and elemental analysis. The crystal structures of compounds 8 and 9 were determined by X-ray diffraction analysis. The distorted tetrahedral geometry around the Sn center in the monocrystals of 8 was revealed, the Schiff base is coordinated to the tin(IV) atom by electrostatic interaction and formation of short contact Sn–O 2.805 Å. In the case of complex 9 the distorted octahedron coordination of Sn atom is formed. The antioxidant activity of compounds as radical scavengers and reducing agents was proved spectrophotometrically in tests with stable radical DPPH, reduction of Cu2+ (CUPRAC method) and interaction with superoxide radical-anion. Moreover, compounds have been screened for in vitro cytotoxicity on eight human cancer cell lines. A high activity against all cell lines with IC50 values 60–160 nM was determined for the triphenyltin complex 7, while the introduction of Schiff base decreased the cytotoxicity of the complexes. The influence on mitochondrial potential and mitochondrial permeability for the compounds 8 and 9 has been studied. It is shown that studied complexes depolarize the mitochondria but don't influence the calcium-induced mitochondrial permeability transition
