Authors: Zarnescu Eugenia Claudia , Zarnescu Narcis Octavian , Sanda Nicoleta , Costea Radu
Published: November 2022

Background and Objectives: This study aimed to investigate the potential risk factors for severe postoperative complications after oncologic right colectomy. Materials and Methods: All consecutive patients with right colon cancer who underwent right colectomy in our department between 2016 and 2021 were retrospectively included in this study. The Clavien–Dindo grading system was used to evaluate postoperative complications. Univariate and multivariate logistic regression analyses were used to investigate risk factors for postoperative severe complications. Results: Of the 144 patients, there were 69 males and 75 females, with a median age of 69 (IQR 60–78). Postoperative morbidity and mortality rates were 41.7% (60 patients) and 11.1% (16 patients), respectively. The anastomotic leak rate was 5.3% (7 patients). Severe postoperative complications (Clavien–Dindo grades III–V) were present in 20 patients (13.9%). Univariate analysis showed the following as risk factors for postoperative severe complications: Charlson score, lack of mechanical bowel preparation, level of preoperative proteins, blood transfusions, and degree of urgency (elective/emergency right colectomy). In the logistic binary regression, the Charlson score (OR = 1.931, 95% CI = 1.077–3.463, p = 0.025) and preoperative protein level (OR = 0.049, 95% CI = 0.006–0.433, p = 0.007) were found to be independent risk factors for postoperative severe complications. Conclusions: Severe complications after oncologic right colectomy are associated with a low preoperative protein level and a higher Charlson comorbidity index.

Published: November 2022

Mycotoxins in food are hazardous for animal and human health, resulting in food waste and exacerbating the critical global food security situation. In addition, they affect commerce, particularly the incomes of rural farmers. The grave consequences of these contaminants require a comprehensive strategy for their elimination to preserve consumer safety and regulatory compliance. Therefore, developing a policy framework and control strategy for these contaminants is essential to improve food safety. In this context, sensing approaches based on metal-organic frameworks (MOF) offer a unique tool for the quick and effective detection of pathogenic microorganisms, heavy metals, prohibited food additives, persistent organic pollutants (POPs), toxins, veterinary medications, and pesticide residues. This review focuses on the rapid screening of MOF-based sensors to examine food safety by describing the main features and characteristics of MOF-based nanocomposites. In addition, the main prospects of MOF-based sensors are highlighted in this paper. MOF-based sensing approaches can be advantageous for assessing food safety owing to their mobility, affordability, dependability, sensitivity, and stability. We believe this report will assist readers in comprehending the impacts of food jeopardy exposure, the implications on health, and the usage of metal-organic frameworks for detecting and sensing nourishment risks.

Published: November 2022

The exact mechanisms of multiple sclerosis development are still unknown. However, the development of EAE (experimental autoimmune encephalomyelitis) in Th and 2D2 mice is associated with the infringement of the differentiation profiles of bone marrow hematopoietic stem cells which are bound with the production of compounds that are harmful for human autoantibodies-abzymes that hydrolyze myelin oligodendrocyte glycoprotein, myelin basic protein, and DNA. It showed that autoimmune patients’ antioxidant IgG antibodies oxidise some compounds due to their peroxidase (H2O2-dependent) and oxidoreductase (H2O2-independent) activities more effectively than those in healthy humans can. It was interesting to identify whether the redox activities of the antibodies change during the development of autoimmune diseases. Here, we analyzed the change in these redox activities of the IgGs from the blood of Th and 2D2 mice, which corresponded to different stages of the EAE development. The peroxidase activity in the oxidation of ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) in the Th (4-fold) and 2D2 (2-fold) mice IgGs, on average, is higher than the oxidoreductase activity is. The peroxidase activity of the Th (1.9-fold) and 2D2 (3.5-fold) mice IgGs remarkably increased during the 40 days of the spontaneous development of EAE. Forty days after the immunization of the MOG peroxidase activity, the IgGs of the Th and 2D2 mice increased 5.6–6.0 times when they were compared with those that presented no increase (3 months of age). The mice IgGs were oxidized with 3,3′-diaminobenzidine (2.4–4.3-fold) and o-phenylenediamine (139–143-fold) less efficiently than they were with ABTS. However, the temper of the change in the IgG activity in the oxidation of these substrates during the spontaneous and MOG-induced development of EAE was close to that which occurred for ABTS. All of the data show that the IgG peroxidase and oxidoreductase activities of EAE mice can play an important role in their protection from toxic compounds and oxidative stress.

In this study, natural Algerian kaolin was used as a support and impregnated with nickel at different loading amounts (2 wt.%, 5 wt.%, and 7 wt.%) in order to prepare a supported catalyst. The wet impregnation technique was used in this preparation; nickel oxide (NiO) was the active phase precursor of the catalyst, and the catalysts were designated as follows: 2%, 5%, and 7% Ni/kaolin. These catalysts were put to the test in catalytic wet peroxide oxidation (CWPO) for degrading the organic contaminant malachite green dye (MG). Analytical techniques such as FTIR spectroscopy, X-ray diffraction, BET, and X-fluorescence were used to examine the structure, morphology, and chemical composition of the support and the produced catalysts. Several parameters, including temperature, catalytic dose, metal loading, hydrogen peroxide volume, and kinetic model were systematically investigated. The combination of improved parameters resulted in a significant increase in the catalytic activity, achieving a high removal rate of MG dye of 98.87%.

Published: November 2022

Propolis, a natural product made by bees with resins and balsams, is known for its complex chemical composition and remarkable bioactivities. In this study, propolis extraction was studied seeking extracts with strong bioactivities using less orthodox solvents, with some derived from apiary products. For that, a propolis sample collected from Gerês apiary in 2018 (G18) was extracted by maceration with six different solvents: absolute ethanol, ethanol/water (7:3), honey brandy, mead, propylene glycol and water. The solvent influence on the chemical composition and antioxidant and antimicrobial activities of the extracts was investigated. Antioxidant potential was assessed by the DPPH free-radical-scavenging assay and the antimicrobial activity by the agar dilution method. Chemical composition of the extracts was determined in vitro by three colorimetric assays: total ortho-diphenols, phenolics and flavonoids contents and the LC-MS technique. To our knowledge, this is the first time that solvents such as honey brandy and mead have been studied. Honey brandy showed considerable potential to extract propolis active compounds able to inhibit the growth of bacteria such as the methicillin-sensitive Staphylococcus aureus and Propionibacterium acnes (MIC values of 100 and 200 µg/mL, respectively) and the fungi Candida albicans and Saccharomyces cerevisiae (MIC = 500 µg/mL, for both). Mead extracts displayed high antioxidant capacity (EC50 = 1.63 ± 0.27 µg/mL) and great activity against resistant bacteria such as the methicillin-resistant Staphylococcus aureus and Escherichia coli (MIC = 750 µg/mL, for both). The production of such solvents made from beehive products further promotes a diversification of apiary products and the exploration of new applications using eco-friendly solutions.

Published: November 2022

A topological index is a numerical parameter that is derived mathematically from a graph structure. In chemical graph theory, these indices are used to quantify the chemical properties of chemical compounds. We compute the first and second temperature, hyper temperature indices, the sum connectivity temperature index, the product connectivity temperature index, the reciprocal product connectivity temperature index and the F temperature index of a molecular graph silicate network and silicate chain network. Furthermore, a QSPR study of the key topological indices is provided, and it is demonstrated that these topological indices are substantially linked with the physicochemical features of COVID-19 medicines. This theoretical method to find the temperature indices may help chemists and others in the pharmaceutical industry forecast the properties of silicate networks and silicate chain networks before trying.
Mn2 Dimers Encapsulated in Silicon Cages: A Complex Challenge to MC-SCF Theory
Authors: Khanna Vaibhav , McGrady John Ewart
Published: November 2022

MC-SCF wavefunctions for three endohedral Mn/Si clusters, Mn2Si10, Mn2Si12, and [Mn2Si13]+, show evidence for strong static correlation, both in the Mn-Si bonds (‘in–out correlation’) and between the two Mn centers (‘up–down correlation’). We use both Restricted and Generalized Active Spaces (RAS and GAS) to place constraints on the configurations included in the trial wavefunction, showing that, particularly in the high-symmetry cases, the GAS approach captures more of the static correlation. The important correlating pairs are similar across the series, indicating that the electronic structure of the endohedral Mn2 unit is, to a first approximation, independent of the size of the silicon cage in which it is embedded.
In Melting Points We Trust: A Review on the Misguiding Characterization of Multicomponent Reactions Adducts and Intermediates
Authors: Neto Brenno A. D. , Beck Pedro S. , Sorto Jenny E. P. , Eberlin Marcos N.
Published: November 2022

We discuss herein the problems associated with using melting points to characterize multicomponent reactions’ (MCRs) products and intermediates. Although surprising, it is not rare to find articles in which these MCRs final adducts (or their intermediates) are characterized solely by comparing melting points with those available from other reports. A brief survey among specialized articles highlights serious and obvious problems with this practice since, for instance, cases are found in which as many as 25 quite contrasting melting points have been attributed to the very same MCR adduct. Indeed, it seems logical to assume that the inherent non-confirmatory nature of melting points could be vastly misleading as a protocol for structural confirmation, but still many publications (also in the Q1 and Q2 quartiles) insist on using it. This procedure contradicts best practices in organic synthesis, and articles fraught with limitations and misleading conclusions have been published in the MCRs field. The drawbacks inherent to this practice are indeed serious and have misguided MCRs advances. We therefore suggest some precautions aimed at avoiding future confusions.

Published: November 2022

The recovery of strategic metals such as rare earth elements (REEs) requires the development of new sorbents with high sorption capacities and selectivity. The bi-functionality of sorbents showed a remarkable capacity for the enhancement of binding properties. This work compares the sorption properties of magnetic chitosan (MC, prepared by dispersion of hydrothermally precipitated magnetite microparticles (synthesized through Fe(II)/Fe(III) precursors) into chitosan solution and crosslinking with glutaraldehyde) with those of the urea derivative (MC-UR) and its sulfonated derivative (MC-UR/S) for cerium (as an example of REEs). The sorbents were characterized by FTIR, TGA, elemental analysis, SEM-EDX, TEM, VSM, and titration. In a second step, the effect of pH (optimum at pH 5), the uptake kinetics (fitted by the pseudo-first-order rate equation), the sorption isotherms (modeled by the Langmuir equation) are investigated. The successive modifications of magnetic chitosan increases the maximum sorption capacity from 0.28 to 0.845 and 1.25 mmol Ce g−1 (MC, MC-UR, and MC-UR/S, respectively). The bi-functionalization strongly increases the selectivity of the sorbent for Ce(III) through multi-component equimolar solutions (especially at pH 4). The functionalization notably increases the stability at recycling (for at least 5 cycles), using 0.2 M HCl for the complete desorption of cerium from the loaded sorbent. The bi-functionalized sorbent was successfully tested for the recovery of cerium from pre-treated acidic leachates, recovered from low-grade cerium-bearing Egyptian ore.

Published: November 2022

Matrine derivatives were reported to have various biological activities, especially the ester, amide or sulfonamide derivatives of matrine deriving from the hydroxyl or carboxyl group at the end of the branch chain after the D ring of matrine is opened. In this work, to investigate whether moving away all functional groups from the C-11 branch chain could have an impact on the bioactivities, such as anti-tobacco mosaic virus (TMV), insecticidal and fungicidal activities, a variety of N-substituted-11-butyl matrine derivatives were synthesized. The obtained bioassay result showed that most N-substituted-11-butyl matrine derivatives had obviously enhanced anti-TMV activity compared with matrine, especially many compounds had good inhibitory activity close to that of commercialized virucide Ningnanmycin (inhibition rate 55.4, 57.8 ± 1.4, 55.3 ± 0.5 and 60.3 ± 1.2% at 500 μg/mL; 26.1, 29.7 ± 0.2, 24.2 ± 1.0 and 27.0 ± 0.3% at 100 μg/mL, for the in vitro activity, in vivo inactivation, curative and protection activities, respectively). Notably, N-benzoyl (7), N-benzyl (16), and N-cyclohexylmethyl-11-butyl (19) matrine derivatives had higher anti-TMV activity than Ningnanmycin at both 500 and 100 μg/mL for the four test modes, showing high potential as anti-TMV agent. Furthermore, some compounds also showed good fungicidal activity or insecticidal activity.
Characterization of Colorants Formed by Non-Enzymatic Browning Reactions of Hydroxycinnamic Acid Derivatives
Authors: Bork Leon Valentin , Rohn Sascha , Kanzler Clemens
Published: November 2022

The browning of plant-based food is commonly understood to result from the enzymatic polymerization of phenolic compounds to pigments, called melanin. However, during the thermal treatment of food, enzymes are deactivated, and non-enzymatic reactions predominate. The extent of the contribution of phenolic compounds to these non-enzymatic reactions has been speculated (“melanin-like vs. melanoidin-like”), but the literature is limited. Therefore, the aim of the present study was to investigate the heat-induced reactions of caffeic acid (CA), para-coumaric acid (CS), ferulic acid (FA), hydrocaffeic acid (HC), and 5-O-caffeoylquinic acid (CGA) under dry conditions. The model systems were characterized by color formation, reactant conversion, and antioxidant properties. Reaction products were analyzed by high-resolution mass spectrometry (HRMS) and nuclear magnetic resonance (NMR) spectroscopy. Decarboxylation could be classified as the driving force for the observed color formation and was significantly impacted by the substitution of the aromatic system. Reaction products were found to contribute to an increase in the antioxidant properties of the model systems. The oligomers described in this study could be incorporated into food melanoidins, contributing to the color and antioxidant properties observed in roasted food rich in phenolic compounds, such as coffee or cocoa.

Published: November 2022

Objective: The aim of this research is to analyze the socio-occupational and health conditions of Intensive Care Units (ICU) health professionals during the COVID-19 pandemic in Spain. In addition, with regard to the working conditions (availability of personal protective equipment—PPE, workload and patient/professional ratio), this research aims to analyze the possible differences depending on the Spanish region that was sampled and their professional category, as well as their relationship with the characteristic symptoms of COVID-19 (myalgias and respiratory distress). Method: A cross-sectional study performed with an online questionnaire, which was spread throughout all of the Spanish autonomous communities/regions. Results: The sample consisted of 461 ICU professionals in Spain, of whom, 94% reported an increase in their workload, and 43% reported a patient/professional ratio that was higher than it usually is. The median professional experience in the ICU was 9.73 years, with 47% of them having less than 5 years of experience in it. About 80% had undergone some diagnostic tests. There is a significant difference in ‘Serology (+)’ in terms of sex, with males having a serology (+) in 26% of the cases and females having it in 13% of the cases (p = 0.011). Most of the professionals (80%) were concerned about a possible infection, and up to 96% were worried about infecting their family members. The most common COVID-19 symptom was a headache, with there being a higher incidence of this in women. Significant differences were observed with respect to the availability of appropriate PPE depending on the Spanish region (i.e., Cataluña had best rate of PPE availability) (p = 0.005). The higher incidence of myalgias and respiratory distress were associated with a lower availability of PPE and a higher patient/professional ratio. Conclusions: The ICU staff reported an increase in their workload, with an increase in the amount of staff who had less experience. A high percentage of them have suffered symptoms, although the proportion of positive tests was low. The most characteristic symptoms of COVID-19 seem to be related to the working conditions. The results show the socio-occupational and health conditions of Spanish ICU professionals during the pandemic and point to the need to establish occupational risk-prevention measures.
Some Classical Models of Particles and Quantum Gauge Theories
Authors: Akhmeteli Andrey
Published: November 2022

The article contains a review and new results of some mathematical models relevant to the interpretation of quantum mechanics and emulating well-known quantum gauge theories, such as scalar electrodynamics (Klein–Gordon–Maxwell electrodynamics), spinor electrodynamics (Dirac–Maxwell electrodynamics), etc. In these models, evolution is typically described by modified Maxwell equations. In the case of scalar electrodynamics, the scalar complex wave function can be made real by a gauge transformation, the wave function can be algebraically eliminated from the equations of scalar electrodynamics, and the resulting modified Maxwell equations describe the independent evolution of the electromagnetic field. Similar results were obtained for spinor electrodynamics. Three out of four components of the Dirac spinor can be algebraically eliminated from the Dirac equation, and the remaining component can be made real by a gauge transformation. A similar result was obtained for the Dirac equation in the Yang–Mills field. As quantum gauge theories play a central role in modern physics, the approach of this article may be sufficiently general. One-particle wave functions can be modeled as plasma-like collections of a large number of particles and antiparticles. This seems to enable the simulation of quantum phase-space distribution functions, such as the Wigner distribution function, which are not necessarily non-negative.

Published: November 2022

Alkaline phosphatase is used as the main marker in the evaluation of successful milk pasteurization, although there is concern about whether this method is appropriate for non-cow milk. We systematically reviewed articles related to ALP in non-cow milk and dairy products. From a total of 183 studies retrieved, 31 articles were included in the review. Our study shows that most research is focused on goat and sheep milk, while other species are rather neglected as far as the use of ALP as a milk safety marker is concerned. More evidence on ALP kinetics is required for non-cow milk and its products and on alternative pasteurization-efficiency markers, such as other enzymes, as these issues are crucial for consumer health.

This paper presents a machine-learning approach for detecting swarming events. Three different classification algorithms are tested: The k-Nearest Neighbors algorithm (k-NN) and Support Vector Machine (SVM), and a newly proposed by the authors, U-Net Convolutional Neural Network (CNN), developed for biomedical image segmentation. Next, the authors present their experimental scenario of collecting audio data of swarming and non-swarming events and evaluating the results from the k-NN and SVM classifiers and their proposed CNN algorithm. Finally, the authors compare these three methods and present the cross-comparison results of the optimal method for early and late/close-to-the-event detection of swarming.

Aves fingidas: Reescrituras del mito de Leda y el cisne en Rubén Darío, Delmira Agustini y Silvina Ocampo
Authors: Barbero Ludmila S.
Published: November 2022

En el Modernismo latinoamericano son abundantes las apropiaciones de elementos de la mitología grecorromana. Entre ellos, propongo analizar las reescrituras del mito de Leda y el cisne que llevaron a cabo Rubén Darío en Cantos de vida y esperanza (1905) y Delmira Agustini en Los cálices vacíos (1913). En el diálogo que se establece entre estos poemas (la respuesta de Agustini a Darío) y entre ambos y el hipotexto mítico es posible ver cómo se traman ciertas ansiedades y violencias en torno a la construcción de los géneros y deseos sexuales. También abordaré una reescritura posterior que recupera y se apropia del poema de Darío: “Leda y el cisne” de Silvina Ocampo (Los nombres 1953). Este último texto se corre de las representaciones canónicas del mito porque pone en primer plano la representación en sí, y ubica el énfasis en el espejo por sobre los personajes “vivos”.
“Hay objetos que una HIJA artista elige para la trama de su ficción”. Subjetividad y soberanía en Oración de María Moreno
Authors: Tellechea Anabel
Published: November 2022

Oración de María Moreno puede leerse como una intervención en el horizonte de debate de las políticas de la memoria. Examinaremos, específicamente, la interpretación que Moreno realiza de las producciones de Albertina Carri (Los rubios) y Marta Dillon (Aparecida) en cuanto imágenes, es decir, como “formas de redistribución de los elementos de la representación” (Rancière El espectador 97), como “imágenes o configuraciones de pensamiento alternativas” (Didi-Huberman Supervivencia 99). En ambos casos, lo material se trabaja de tal manera que desplaza la posibilidad de correspondencias entre los objetos presentes y los sujetos ausentes. Asimismo, nos ocuparemos del presupuesto que subyace a la intervención de Moreno, a saber, el posicionamiento y la concepción de sujeto (Didi-Huberman Cuando las imágenes; Butler Dar cuenta) que distingue a la escritora y que ella reconoce en Carri y Dillon; una posición móvil, relativa, que rechaza lo identitario, y que Moreno asocia con la soberanía (Derrida La bestia y el soberano).
Las huellas del Che o cómo hacer que un muerto camine: algunas reflexiones en torno a los desplazamientos, la poesía y las imágenes
Authors: Fernández Rocío
Published: November 2022

La muerte del comandante Ernesto Che Guevara en Bolivia impactó de lleno en todo el movimiento revolucionario latinoamericano pero especialmente en La Habana. En este artículo me propongo revisar las operaciones semióticas que llevan adelante los discursos políticos, las imágenes y la literatura de fines de los ´60 para continuar el legado del Guerrillero Heroico. Para eso, y haciendo foco en los desplazamientos subjetivos y territoriales que caracterizaron la vida de Guevara, reflexiono en torno a las maneras en las que los signos y el trabajo editorial y/o de reproducción visual lograron multiplicar y repotenciar el concepto de huella.

Esta contribución propone un análisis detallado del poema “Sangre de alumnos”, de Omar Pérez López, incluido en Algo de sagrado, 1994. Para explicitar ciertas alusiones a la biografía y el legado cultural de Ernesto Guevara en Cuba, se convocan intertextos literarios y cinematográficos en relación con las nociones de filiación y paternidad, violencia y géneros sexuales. Así se hace más clara la disidencia del poema y de este acercamiento crítico respecto a las lecturas hagiográficas dominantes.

Published: November 2022

The article substantiates the content of the concepts "criterion" and "indicator" for measuring the formation of diagnostic competence of future specialists in physical training and sports of the Armed Forces of Ukraine (hereinafter – respondents) in the process of their professional training. The scientific approaches of foreign and domestic scientists to their definition have been analyzed and summarized. The choice of the author's criteria and indicators was carried out considering the diagnostic function of the military-professional activity of the respondents – future officers as specialists in physical training and sports in military units.
On the basis of generalization of scientific sources and taking into account the specifics of respondents' professional activity, the criteria of assessment of the formation of their diagnostic competence, containing value-motivational (complex of values and motivations of diagnostic activity), intellectual (theoretical and practical knowledge concerning their diagnostic activity), psychological (communication, principality, tolerance, objectivity) and reflective (methods, techniques, methods and means of diagnosis) are determined. For each criterion, respectively, the indicators of measuring the formation of a particular component of the diagnostic competence of the respondents in the process of their professional training at Military Academies and Army War Colleges.
The article presents the criteria and characteristics by means of which the degree of merit of the research goals is evaluated. Diagnosing of physical preparedness and readiness of respondents is carried out on leading provisions of methodological approaches to diagnosing of their professional activity. Criteria and indicators are necessary for measuring the formation of the respondents' diagnostic competence, by which it is possible to find out its formation at different stages of their military-professional and professional training. In this connection the allocated criteria should be impartial and include attributes of their diagnostic competence.

In the process of educating modern schoolchildren, martial arts classes become important, namely judo classes, which can be used to develop not only physical qualities and abilities, but also moral and volitional characteristics, the development of which significantly affects the formation of a personality. The article considers the results of experimental work on the implementation of the technology of moral and volitional education of high school students who practice judo. The technology of moral and volitional upbringing of children by means of judo included three stages: value-oriented; development and harmonization; improvement and generalization of moral and volitional qualities. At all stages, the emphasis of the predominant action shifted to the structural components of the moral and volitional sphere: cognitive, emotional, volitional, motivational, and behavioral. The purpose and objectives of the above-mentioned stages determined the specifics of sports activities, the role and position of the coach-tutor, forms, and methods of education, as well as features of pedagogical interaction with parents and school, aimed at improving the moral and volitional education of young judokas. Thus, the need for pedagogical justification of teaching judo to students determines the relevance of our study, which identified pedagogical conditions, as well as identified the core elements of the technology of moral and volitional education of students by judo, which became the novelty of the research. The following research methods were used to solve the problems: analysis and synthesis of scientific and methodological sources on the peculiarities of the development of moral and volitional qualities; pedagogical observation.
It is established that the most important sources of moral and volitional formation of student youth at the initial stage of classes are the study of history, jute etiquette.  Collective development of etiquette leads to group self-regulation.  Students willingly participate in the process of self-control and control of group behavior.
For an objective assessment of the moral and volitional upbringing of students also developed criteria and indicators determined by the purpose of the formation of the moral and volitional sphere of the student's personality. Improvement of moral and volitional qualities and experience of moral and volitional behavior was carried out.
STRESSING OF DERIVATIVE WORDS (REGARDING METHODOLOGY)
Authors: Kobyrynka H.
Published: November 2022

The article is devoted to the study of the Ukrainian accent system. The subject of the analysis was the issue of the analysis methodology for derived words. The article focuses what requires special attention in the study of accentuating derived words; outlined the issues that arise before the accentologist researcher.
The expediency of conducting a separate study of accentuation of non-derived and derived words is noted, since for non-derived words the stress pattern and place of stress are not determined by other characteristics of the word, unlike with derived words, the accentuation of which can be influenced by various affixes.
It is emphasized that the analysis of verbal stress in the morphological aspect involves the study of the regularities of each part of the language or individual grammatical forms in particular. After all, words of different grammatical classes, formed with the help of the same morphemes, can have different accent characteristics.
Various dialectological studies were used to illustrate the accentuation of derived words, in particular, the works of M. V. Nikonchuk "Materials for the lexical atlas of the Ukrainian language (Wesr bank Polissya)" (1979), "West bank Polissia dialects in linguistic and geographical coverage" (2012), as well as the educational and methodological manual of V. M. Moisiyenko and H. I. Hrymasevych "Unity in diversity. Polishchuks" (2018), in which recordings of the dialect speech of the Polishchuks are presented.
The study was carried out taking into account the relationship between stress and the morphological structure of the word. In the Ukrainian language, there are a lot of words that have the same accentuation characteristics as creative words. At the same time, there are derived words that do not retain the accent of the original word, since their accentuation characteristics are influenced by prefixes and suffixes.
The analysis of accentuation of derived words made it possible to outline those issues that are relevant and require a detailed accentuation study. In particular: "Is the accentuation model of the creative (writing) word preserved?", "Which morphemes and in which grammatical classes drag the stress onto themselves, and which do not affect the mobility of the stress?", "In which direction does the stress move: from the root of the word to the prefix, suffix or vice versa ?", "Does the length of the word affect the place of stress? " etc.
It was found out that prefixed, suffixed, prefixed-suffixed words can have different accentuation characteristics in Ukrainian dialects. The differentiation of the Ukrainian dialect continuum based on the accentuation of derived nouns is illustrated.

Published: November 2022

The article is devoted to the problem of sociolinguistic identification of speakers in Spoken American Academic Discourse. The article examines the existing approaches of humanitarian scientists to the concept of identification and personal identity, draws parallels between them, and outlines the distinctive characteristics of each of the concepts. The concept of social and personal identities is also characterized, the types and forms of identification are presented. Considerable attention is paid to consideration of the concept of gender and professional identity. The concepts of identity and discursive community are analyzed. In particular, statistical data are given on the use of hedging markers in academic discourse. The research was carried out on the material Michigan Corpus of Academic Spoken English (MICASE – Michigan Corpus of Academic Spoken English). The results of statistical verification of the use of hedging markers are presented taking into account the gender of the speakers, the academic role of the communicators and the subject area in which the communication takes place. The publication presents the classification of hedging markers and their role in speech as a means of identifying speakers in academic discourse. The classification of hedging markers is developed with a division into classification groups, in particular, as the use of markers oriented on the speaker, on the listener, and markers oriented on the organization of discourse. Each of the three groups contains subgroups and examples of markers for reducing the categorization of speech, obtained by sampling from the transcript of academic classes conducted by the corresponding categories of speakers, located in the database of the Michigan Corpus of Academic Spoken English (MICASE - Michigan Corpus of Academic Spoken English).
LEXICAL BASE OF SURNAMES OF ZHYTOMYR REGION (BASED ON THE MATERIAL OF THE "NATIONAL BOOK OF MEMORY OF THE VICTIMS OF THE HOLODOMOR OF 1932–1933 IN UKRAINE")
Authors: Yashchuk L. , Tytarenko V.

The article describes the onymic and appellative lexicon reflected in the bases of the surnames of two districts of Zhytomyr region – Novohrad-Volynskyi and Ovrutskyi. The analyzed surnames are certified in the "National Book of Memory of the Victims of the Holodomor of 1932-1933 in Ukraine. Zhytomyr Region", the main source base of which is the funds of the State Archives of Zhytomyr Region and the archives of the Office of the Security Service of Ukraine in Zhytomyr Region.
I.I. Kozubenko, the historical anthroponymicon of the Zhytomyr region of the 16th–17th centuries, studied the unofficial hereditary names of the Middle Polissia, in particular, the lexical-semantic features of surnames were studied by L.V. Yashchuk. The relevance of the proposed research lies primarily in the lack of research devoted to the anthroponymy of the Zhytomyr region in the first half of the 20th century.
In the article, surnames are classified into three groups according to the semantics of creative bases: 1) surnames based on anthroponyms (Christian and Slavic autochthonous names); 2) surnames based on appellative-anthroponymic names; 3) surnames based on appellative names.
The analysis of anthroponymic surnames showed that male Christian names (full, truncated, suffixed, truncated-suffixed) took an active part in their formation. Most often, surnames were formed from suffix variants of names: Vasyuta, Yorikov, Levchenko, Yukhymchuk. Sometimes surnames are motivated by female Christian names: Hannoshin, Kulinych, Oryshchuk; and Slavic autochthonous composite names in various structural variants: Kazmirchuk, Berchuk, Skoryk.
Among the surnames based on appellative-anthroponymic names, in the "nomina personalia" category, the names of people based on external characteristics and physiological features are widely represented: Dovganyuk, Kralya, Lysak, Pobelonyy; internal features, character traits, behavior, temperament, speech: Burma, Dyvak, Nyukalo, Plokhotyuk. In the surnames of the "nomina impersonalia" category, the vocabulary for the designation of representatives of the fauna and their body parts is most fully reflected: Sparrow, Cat, Tetera, Tail; household items, work tools, their parts and other items: Baryluk, Korzun, Tychenok, Shkrab.
Оne-component surnames are most often motivated by appellative names based on the type of activity or profession: Kovalchuk, Lavnyk, Ogorodnik, Shkolyar; and oikonyms, including those of Zhytomyr region: Barashovets, Divynskyi / Dyvynska, Levkivskyi, Skorostetskyi / Skorostetska.
THE PROBLEM OF SYMMETRY / ASYMMETRY IN THE NOVELLA GENRE BY B. PRUS
Authors: Kovpik S.
Published: November 2022

The paper deals with the peculiarities of the novella genre of the Polish writer Boleslaw Prus. The author makes an attempt to systematize the research results of Polish and Ukrainian literary study experts on the problem of symmetry / asymmetry in the novella genre by Boleslaw Prus. It focuses on the aesthetic views of the writer, his own concept of total harmony and the reflection of the naturalistically existing reality in the novella. The author’s experiments with the novella genre should be considered as innovative ones for the time period of the end of the 19th century, as B. Prus consciously violated the canons of the 19th century novella genre, which strictly regulated its content.
Prus successfully combined the elements of other literary genres in his novellas. The writer preferred to make experiments with the composition of the literary work, and therefore resorted to using mathematical techniques in the construction of novellas. B. Prus believed that it was a new way of revolutionary changes in the structure of the novella genre, which significantly made it free from all canons. The writer clearly supported the idea that the whole novella can be simplified to one sentence, and the sentence can be expanded into a large work of fiction due to the writer’s artistic imagination.
The principle of compositional symmetry in the novellas by B. Prus was ensured by the use of repetition, which allowed the author to arrange the events of the literary work around the important facts, details, objects, etc.
It is stated that B. Prus did not consider or determine a special plan for writing a novella in advance, but basically wrote the literary work, sourcing from life and its realities. In his concept of perfection, B. Prus pondered such important categories as: harmony, rhythm, order and proportion. According to the writer these categories were the most naturalistic ones, and therefore, with their help the beauty of human or the beauty of nature could be described in the best way.
