Authors: Mazaraki Anatolii , Prіtulska Natalia , Aslanyan Sergey , Antiushko Dmytro
Published: December 2023

In order to guarantee the appropriate level of safety and quality of food products, integrated management systems are now actively used. To prevent the emergence of economic problems, to understand the financial value of all the organization's assets, it is important to assess their value, in particular, management systems. Integrated safety and quality management systems of special food products are defined as the object of the research. Their implementation makes it possible to ensure compliance with legislation, increase consumer satisfaction, and business excellence.
The main international act regulating methodological aspects of assessment is the International Valuations Standards (IVS). It defines the terminology, procedure of organization, assessment, approaches, methods, reporting of results. It was established that when evaluating integrated management systems, it is recommended to use a cost approach. This is justified by the need to determine the amount of funds to ensure compliance with legislation, meeting the needs of consumers and stakeholders. It is appropriate to use methods of reproduction and substitution. The cost of the mentioned systems of the organization was determined by the method of reproduction, which as of the beginning of October 2023 amounted to UAH 167.6 thousand and UAH 34.7 thousand, respectively.
Recommendations for estimating the cost of integrated management systems have been devised. Their main content is the need to take into account the level of changes in the market rate of the currency, in which the value is estimated, the coefficient of moral aging, based on the service life. Their consideration made it possible to estimate the cost of the investigated systems at UAH 144.6 thousand and UAH 30.0 thousand, respectively. This could contribute to more effective management of the organization's resources, investment in financial management systems
OAT GUM: STRUCTURE, PROPERTIES, PRODUCTION, APPLICATION IN THE FOOD INDUSTRY
Authors: Kosiv R.
Published: December 2023

Oat gum (β-glucan, glycan) belongs to the group of soluble dietary fibers. Due to their important functional properties, cereal β-glucans are used to reduce the level of cholesterol in the blood, alleviate the symptoms of diabetes, lower blood pressure, and prevent cardiovascular and oncological diseases. Sources of β-glucans are yeast, mushrooms, bacteria, barley, oats. The use of secondary resources of barley and oat processing as a source of β-glucans has both economic and environmental significance. Cereal β-glucans consist of β-D-glucose monomers connected by (1,3)- and (1,4)-glycosidic bonds. β-Glucan dissolves well in cold water and is insoluble in ethyl alcohol. It is able to form very viscous solutions at low concentrations. The viscosity of solutions depends on the concentration and molecular weight of β-glucan. The rheological properties of aqueous gum solutions do not depend on the pH of the medium. The presence of NaCl in concentrations of more than 0.5% leads to a decrease in the viscosity of solutions, and the addition of sucrose in the amount of 20-45% increases the viscosity. The technological features of obtaining β-glucans are related to the method of their extraction from natural sources. Extraction of oat gum from oat bran or rolled oats involves alkaline treatment of flour at 50-70 °C and pH 8.0-10.5, removal of starch and proteins, precipitation of oat gum with alcohol and separation by centrifugation. Solubility, degree of extraction, and yield of β-glucan from oats depend on particle size, pretreatment of grain raw materials, and extraction conditions (temperature, pH, extractants). β-Glucan is isolated from the extract by dialysis, ultrafiltration or alcohol precipitation. When using dialysis, highly viscous β-glucan is obtained, but with a lower yield; ultrafiltration and alcohol precipitation allow a higher yield of β-glucan with lower viscosity. Oat gum can be introduced into a wide range of food products to provide new functional properties and improve nutritional quality, includ ng wheat bread, bakery products, cookies, pasta, soft drinks, as a fat substitute in dairy and meat products. It performs the technological functions of a thickener, gelling agent, stabilizer or coating in food systems.

Published: December 2023

Este artigo tem como objetivo discutir como a globalização está influenciando o desenvolvimento e a implementação dos currículos escolares em diferentes partes do mundo. Para alcançar esse objetivo, foi realizada uma revisão da literatura sobre o tema, com o objetivo de identificar as principais tendências internacionais em educação que estão influenciando os currículos escolares, bem como as mudanças que estão ocorrendo na forma como os currículos são desenvolvidos e implementados. Os resultados indicam que a globalização está levando a uma maior diversidade e inclusão nos currículos escolares, com uma maior ênfase em temas como direitos humanos, sustentabilidade, diversidade cultural e linguística. Além disso, as tecnologias digitais estão desempenhando um papel cada vez mais importante na elaboração e implementação dos currículos escolares. No entanto, também existem desafios a serem enfrentados, como a necessidade de equilibrar as demandas do mercado de trabalho com os objetivos educacionais e a necessidade de promover a inclusão e a equidade nos currículos escolares. Concluímos que os educadores precisam estar atentos às tendências internacionais em educação e às mudanças na forma como os currículos são desenvolvidos e implementados, a fim de garantir que os alunos estejam preparados para enfrentar os desafios do mundo globalizado. Sugere-se que pesquisas futuras se concentrem em explorar as implicações da globalização no currículo escolar e nas práticas educacionais, bem como em desenvolver abordagens inovadoras para a elaboração e implementação de currículos mais inclusivos e relevantes para o contexto globalizado.

Published: December 2023

Este artigo objetiva compreender a proposta da Base Nacional Comum Curricular (BNCC) para o ensino e a aprendizagem da história e cultura indígena no componente curricular de História, nos anos finais do Ensino Fundamental, a fim de ter a compreensão do que deve ser trabalhado nessa etapa da Educação Básica. Trata-se de uma pesquisa do tipo documental e bibliográfica, com abordagem qualitativa e exploratória, tendo os objetos de conhecimento e Habilidades da BNCC de História dos 6º aos 9º anos, relativas aos povos indígenas, como corpus de análise. Acredita-se que apesar da existência de discursos na defesa da diversidade cultural e identitária, bem como em um ensino que promova o conhecimento dos povos indígenas e suas contribuições históricas, sociais, econômicas e culturais, a BNCC, em parte, estrutura o componente curricular de História sob uma perspectiva tradicional e eurocêntrica, dividindo seu ensino de forma quadripartite e colocando os povos europeus na centralidade da narrativa histórica.

Published: December 2023

O artigo afirma a força do encontro entre currículos, histórias em quadrinhos e infâncias para potencializar os movimentos aprendentes que abrem outros possíveis para pensar e viver a Educação. Problematiza os efeitos que o encontro das crianças com as histórias em quadrinhos produz, instigando movimentos do pensamento, movimentos aprendentes e inventivos “[...] dando língua aos afetos que pedem passagem”, além de questionar o modo como as histórias em quadrinhos convocam as crianças à fabulação, provocando outros currículos em movimentos aprendentes inventivos. Utiliza a cartografia como metodologia de pesquisa, acompanhando, nos encontros das crianças de duas turmas de 4º anos de uma escola pública municipal com os signos, vibrações, intensidades, invenções e experimentações, enfim, composições a partir da vida que pulsa nos cotidianos escolares. Tal encontro pode forçar o pensamento em diferentes processos de criação do aprenderensinar, em movimentos inventivos que fabulam outros currículos, outras docências, outras estéticas, outros possíveis de vida. Aponta que o encontro com as histórias em quadrinhos pode convocar as crianças à fabulação, instigando conversas, indagações e criação de mundos outros; pode potencializar os currículos e as docências em movimentos aprendentes, deslocando sentidos, significações e ressignificações, afirmando a vida em sua potência.
SOLIDÃO DE UMA EDUCAÇÃO COTIDIANA
Authors: Silva Tamili Mardegan da , Piontkovsky Danielle
Published: December 2023

Este texto se dá como efeito da produção de uma tese, em uma tentativa de problematização dos modos de vivência da solidão preponderantes na contemporaneidade educacional, em meio ao que se configura como solidões pautadas nas noções de carência, de melancolia e de precariedade, conferindo um status negativo à solidão. A partir de intercessores como Deleuze, Guattari e Nietzsche, aponta outras formas de se considerar a solidão atrelada aos currículos, formas estas mais desprendidas da compreensão de ser humano como um sujeito enfraquecido. Aproxima a produção curricular a uma “[...] boa solidão, a solidão livre, a que vos permite seguir sendo bons em qualquer sentido” (NIETZSCHE, 2005, p. 35), cartografando os processos de produções curriculares intensificados pela potência da solidão como afirmação de uma vida inquietada e atravessada pelos devires que forçam o pensamento em busca da não subordinação. Busca, desta maneira, evidenciar as práticas de criação de espaços inéditos no campo do currículo, promovidos pela solidão em meio à lógica produtiva contemporânea, em seus múltiplos sentidos possíveis, nos encontros de uma educação cotidiana.

Este artigo é resultado da pesquisa de mestrado intitulada O fotográfico e a professoralidade: uma cartografia de aproximações e distanciamentos. Nele rastrea-se processos de criação na perspectiva de uma esquizoanálise de memórias, tensionando, entretanto, sem negar frontalmente a ideia de santidade impressa na laicidade da escola, num modo de estetização do espaço escolar e, alhures, produzir linhas de fuga singularizantes a partir do fotográfico, cartografando algumas passagens dessa trilha, embate entre santidade, pérolas e porcos em meio ao lamaçal sombrio e fecundo do processo de vir a ser professor, para alcançar um certo modo de ser metaestável. Adota como método a cartografia e toma a esquizoanálise como inspiração processual da análise. Aponta como resultados centrais emergentes: percurso cartográfico desse jogo de sombras permite experimentar ser encharcado pelos acasos, pelas pequenas formas dos acontecimento microfísicos, na educação básica como docente de arte,  pela luz que chega, pelo peso do ferro que morre, pela leveza do ar, tudo isso retorna como uma energia potencial pelo fotográfico, que rearranja esses vetores de força e produz uma existência outra, uma existência artística, encarnada por inteiro no presente.
Early Paleolithic Sites on the 145-Meter Terrace of the Usisha River in Central Dagestan
Authors:   Institute of History, Archaeology and Ethnography of the Daghestan Federal Research Center of the Russian Academy of Sciences, Taymazov Artur
Published: December 2023

The article considers the characteristics of the stone inventory from the sites Ainikab 3, Ainikab 4 and Ainikab 6 of the Early Paleolithic located on the 145-meter terrace of the Usisha River in Central Dagestan. Based on the generalization of paleogeographic data, the age of the terrace deposits has been established in a wide range within the first half of the Middle Pleistocene. The stone industries of the sites are mono raw material, based on the use of local Cretaceous flint of various shades of gray. Knapping of raw materials is characterized by the simplest methods of obtaining flakes mainly by unidirectional longitudinal removal without preliminary cores preparation. Flakes were the main type of blanks for tools, including for large cutting, splitting and crushing tools. In addition, flint fragments and nodules were used as blanks. The tools include unifacial and bifacial choppers, heavy-duty picks of triangular cross-section or a pointed end, flat picks, various retouched tools on flakes and fragments (scrapers, knives, notched tools, points, retouched flakes). The most significant feature of the industry under consideration, which distinguishes it from the older Oldowan complexes of Central Dagestan, is the presence of archaic forms of bifaсes in the tool set. These finds are the earliest known bifaсes in inner Dagestan and one of the oldest in the North Caucasus. The bifaсes are diagnostic for Acheulean. The presence of these tools together with piсks and other cutting tools in the stone inventory of the sites makes it possible to define the stone industry of these sites as Acheulean. These finds make it possible to include the inner Dagestan in the spread area of the Acheulean culture of the North Caucasus thereby expanding its territory.

Published: December 2023

Aim. To analyze the immediate outcomes of reinterventions after Ross procedure.

Material and methods. From April 2009 to December 2022, 224 Ross operations in adults were performed at the Federal Center for Cardiovascular Surgery. The retrospective study included 17 patients who required repeated interventions (14 men/3 women). The mean age of the patients was 38±11 years, with a minimum age of 21 and a maximum of 54 years. A history of infective endocarditis was revealed in 4 (23,5%) patients, hypertension — in 3 (17,6%) patients. Of the 17 included patients, 15 patients underwent the classic Ross operation ("full root replacement"), while 2 — a modified technique (1 — wrapping with aorta, 1 — wrapping with a Dacron graft). Annulus enhancement was previously performed in 3 patients.

Results. Interventions on the pulmonary autograft and homograft were performed in 16 and 4 cases, respectively. The main indication for pulmonary autograft intervention was aortic regurgitation in 15 cases, and neoaortic aneurysm in 14 cases. In 3 patients, there was pulmonary homograft stenosis, while in 1 case — thrombosis. Two patients required interventions on other valves: 1 — mitral valve stenosis, 1 — severe tricuspid regurgitation. Mean reoperation, cardiopulmonary bypass and myocardial ischemia time were 289±62, 126±35 and 98±22 min, respectively. Combined interventions were performed in 6 cases. David valve-sparing procedure was performed in 9 patients, Bentall-de Bono technique — in 3, aortic valve repair — in 2, mechanical aortic valve replacement — in 2, supracoronary ascending aorta replacement — in 2, pulmonary homograft replacement — in 2, pulmonary homograft thrombectomy — in 1, pulmonary homograft repair — in 1 patient, mitral valve replacement — in 1 patient, tricuspid valve repair — in 1 patient. One patient required resternotomy for bleeding. There were no postoperative complications (perioperative myocardial infarction, acute kidney injury, stroke, sternal infection, cardiac tamponade) and deaths. The median length of stay in intensive care unit was 21 [16-23] hours.

Conclusion. Reoperations after the Ross procedure may be required for different pathologies, but all can be performed surgically with a high safety in experienced operator.

Hypertension, cardiovascular risk and exercise in middle-aged and elderly people: a narrative review
Authors: Vyalova M. O. , Shvarts Yu. G.
Published: December 2023

Hypertension (HTN) is widespread among middle-aged and elderly people, including those doing sports. For the first time in 2020, the European Society of Cardiology guidelines on sports cardiology and exercise in patients with cardiovascular disease included adult and elderly patients in a separate group. However, this is a heterogeneous category of patients, including everyone over 35 years of age. Therefore, admittance of athletes to training and competitions still remains at the discretion of physician.

Aim. To assess the relationship and mutual influence of hypertension, other cardiovascular risk factors and sports in middle-aged and elderly people.

Material and methods. Our narrative review is based on 50 articles published on Pubmed, Scopus, Web of Science and eLIBRARY.ru, selected using the keywords "veteran athletes", "arterial hypertension", "cardiovascular risk", "physical activity". Related papers over the past 5 years were evaluated.

Results. Currently, there is a trend toward an increase in the number of veteran athletes whose problems are not reflected in guidelines on sports and exercise.

Conclusion. In the future, large randomized studies are needed to assess the response of blood pressure (BP) to intense exercise, as well as to determine the normal BP response and clear strategy to manage this category of people, depending on the presence of hypertension.

Among various diagnostic methods, echocardiography (EchoCG) is most often used to identify Takotsubo syndrome. Left ventricular apical ballooning and the absence of permanent local contractility disturbances makes it possible to confirm the diagnosis. Currently, the available literature provides insufficient data on longitudinal strain (LS) of various cardiac chambers in this condition. The current case report demonstrates complete restoration of left heart LS within 1 month with its initial significant decrease.

Aim. To assess the compliance of the management of patients with heart failure (HF) with quality criteria (QC) for health care, including discharge instructions for patients.

Material and methods. Hospitalizations of patients aged over 18 years with HF (ICD 10 code — I50.x) during the period from January 1, 2019 to October 1, 2020 were randomly selected from the "Chronic Heart Failure" registry of St. Petersburg. Discharge and post-mortem summaries were assessed for compliance with the quality criteria listed in the 2020 Russian Chronic Heart Failure guidelines.

Results. The study included 553 patients (women, 71,1%, mean age, 82,0±9 years, comorbidities: hypertension — 99,1%, coronary artery disease — 97,6%, chronic kidney disease — 53,2%, diabetes — 32,6%). Electrocardiography (QC № 1) was performed in 94,2% of patients, chest radiography (QC № 2) 91,7%, echocardiography (QC № 3) — 81,0%, but the results were not always informative. The exact ejection fraction (EF) value was reported in 55,4% of patients. Laboratory examination corresponded to QC № 4-6 in 20,3% of cases and was performed in 53,3-94,9%. Natriuretic peptides (NPs) were not determined (QC № 7-0%).

The completeness of intravenous therapy (QC № 8) was not assessed due to insufficient physical examination data.

Oral therapy (QC № 9) was prescribed frequently as follows: renin-angiotensinaldosterone system inhibitors (RAASo) — 93,3%, beta blockers (BBs) — 85,4%, mineralocorticoid receptor antagonists (MRAs) — 78,7%. However, triple RAAS+BB+MRA therapy was carried out in 54,1% of HF cases with EF <50% and no contraindications.

Diet was recommended in 87,1% of summaries, water-salt regimen — 53,3%, drug titration — 8,2%. The date of visit to outpatient cardiologist was indicated in 10,0%.

Conclusion. With the exception of NP assessment, the scope of paraclinical studies corresponded to the QC in the majority of patients. Optimal therapy was prescribed to 54,1% of patients with EF <50%. An early outpatient visit after discharge was indicated in 10,0% of summaries.

Due to the large number of complications and decreased quality of life after coronavirus disease (COVID-19), physical and psychological rehabilitation of patients is relevant. However, the effectiveness of rehabilitation on endpoints has not yet been demonstrated.

Aim. To determine the effectiveness of different rehabilitation options in hospitalized patients with COVID-19 on the development of long-term adverse cardiovascular events 1 year after discharge.

Material and methods. In a single-center, non-randomized observational study, 3 groups of patients were formed after hospitalization with COVID-19: I — with telemedicine rehabilitation (n=118), II — with rehabilitation in a specialized department (n=46) and III — without rehabilitation (n=175). After 1-year followup, groups were compared regarding following endpoints: cardiovascular mortality, myocardial infarction, stroke, pulmonary embolism, atrial fibrillation and cardiovascular hospitalization. Propensity score matching analysis was used to optimize differences between comparison groups.

Results. Rehabilitation after hospitalization of patients with COVID-19, both in the hospital and remotely for 1 year, helps to reduce cardiovascular hospitalization rate. In addition, remote rehabilitation reduces cardiovascular mortality.

Conclusion. Both rehabilitation options reduce the incidence of cardiovascular hospitalization compared to no rehabilitation.

Application of International Water Law in Eden: Environmental Protection of the Mesopotamian Marshes in Southern Iraq
Authors: Stevens Michelle
Published: December 2023

Southern Iraq’s Mesopotamian Marshes are fed by the Tigris and Euphrates watercourses. Conflicts in the Tigris-Euphrates Basin over water use and quality are among the most contentious in the world. Increased upstream water withdrawals exacerbated by desertification and regional changes in precipitation and temperature have created a serious water shortage that is becoming increasingly severe. These wetlands need cooperation, reasonable use, and no harm by all watercourse states, especially Turkey, in order to guarantee their survival and conservation. Recent history has not been kind to the Mesopotamian Marshes of southern Iraq or the people that inhabit them. The area has been the scene of three wars and military conflicts over water.
Hydraulic Fracturing: Potential Impacts to Wetlands
Authors: Sutter Lori
Published: December 2023

Unconventional oil and gas extraction using hydraulic fracturing has disrupted traditional energy technologies. Shale formations are a vast global resource facilitating a worldwide transition to gas-centric economies. While hydrocarbon reserves in shale formations exist globally, most of the production of gas from shale currently occurs in North America. With over 50,000 new unconventional oil and gas wells being drilled annually since 2000 in central North America alone, and a likely production growth of 60% in the U.S. It is no surprise that unconventional gas drilling has received much attention in recent years. However, its potential impact on natural resources, particularly water quality and quantity, has also garnered much attention in the media and more recently in the scientific literature. Adding fuel to this controversy is a the recent draft EPA report press release with its headline: Assessment shows hydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources and identifies important vulnerabilities to drinking water resources.

Restoring the Garden of Eden: Negative Impacts by Ali Abdul Zahra Douabul and Sama Sameer AlMaarofi
Authors: Douabul Ali
Published: December 2023

Widely known as the “Garden of Eden”, the extensive Mesopotamian Marshes in Iraq once teemed with life. The marshes were the source of the Shatt Al Arab River and provided fresh water and aquatic resources to many communities downstream. Almost half a century of poor management and intentional drainage by military campaigns, government diversion and irrigation usage have resulted in a substantial deterioration of water quality and subsequent loss of wildlife and habitat. With good intentions, inundation efforts were implemented and additional measures are planned by the Iraqi government to regulate water flow; however decisions have not been based on sufficient scientific data and the complex marshland interactions have not been fully understood. A common misconception is that salinity increases have resulted from Arabian Gulf salt intrusions. Field studies conducted through the Marine Science Centre at the University of Basrah (Iraq) investigated various environmental parameters pertaining to hydrology, water quality, ecology and sedimentology between 2004 and 2013 within the Shatt Al-Arab. The data highlights the integral role of the marshes in maintaining water quality in the Shatt Al-Arab and that the marshes are the main source of salt upstream of the Shatt Al-Arab.
Species Richness of Cypress Dome Vegetation in West-Central Florida, USA
Authors: Cameron1 Cortney
Published: December 2023

Cypress domes are relatively small forested depressional wetlands common in the southeastern United States. The vegetative species richness of cypress domes is quantified using 15 years of annual vegetation data for 41 relatively unimpacted cypress domes in west-central Florida. Wetland species richness was normally distributed, with a median of 73 species and standard deviation of 16 species. Across the sample, 396 species representing 204 genera and 92 families were observed, with the jackknife estimator predicting a species richness of 516, much higher than previous observed or predicted values for cypress domes. Using a bootstrapping technique, the effects of increasing the sampled number of years and wetlands on species richness estimates were assessed, with fewer years or wetlands resulting in considerably lower estimates of richness. The results demonstrate the major contribution of cypress domes to regional biodiversity and the value of long-term monitoring at multiple wetlands.
Restoring a First Order Stream and Adjacent Riparian Wetlands In West Virginia: Integrating Lessons from Science and Practice
Authors: MacKenzie Andrew
Published: December 2023

Stream and wetland mitigation knowledge and understanding are rapidly evolving. However, the objectives of mitigation are wide-ranging. In 2021, a branch of Deckers Creek (Preston Co., West Virginia, USA) was restored by bank recontouring, reconnecting the incised channel to the constructed bankfull bench floodplain, creating small wetlands, and planting native riparian vegetation. Our research objectives were to 1) provide annual biodiversity and abundance data before, during, and after mitigation efforts and 2) assess woody-vegetation growth (height and diameter) and survivorship of a 10% biochar and 90% compost mixture. The complexity of mitigation warrants discussing challenges before, during, and after mitigation occurs. During restoration efforts, we encountered several challenges that were overcome through perseverance and collaboration. We incorporated ideas and practices from academia and the private sector to provide a detailed list of challenges encountered during our mitigation efforts, the solutions enacted, and future management implications to streamline mitigation planning
Importance of Vegetation for Identifying Wetlands in the Lower Mainland Fraser Valley region of British Columbia, Canada using Prevalence Index, Hydrophytic Cover Index, and Dominance Ratio
Authors: Standish Jace
Published: December 2023

The Lower Mainland Fraser Valley (LMFV) in British Columbia (BC), Canada is a complex and high stakes environment for wetland identification (Figure 1). High precipitation, subdued topography, and complex site history combine to present formidable challenges to wetland identification and management. Over the last 100+ years, the LMFV has undergone intense and rapid changes. Originally the land was a natural assortment of bogs, swamps and upland forests, which was then cleared for agriculture, and now is undergoing accelerating urban development. Land use competition is intense. Stakes are high: identification of wetlands can make or break development deals. Wetlands are protected in BC by the Water Sustainability Act, and administration is usually through municipal governments and bylaws. Jurisdictional wetlands are identified and mapped as part of a development permitting process.
Naturalistic Control: W. T. Penfound, T. F. Hall, and A. D. Hess and Malaria Control in Tennessee Valley Authority Reservoirs
Authors: G. van der Valk Arnold
Published: December 2023

Wetland and aquatic plants in the shallow water in new Tennessee Valley Authority (TVA) reservoirs provided food and shelter for the larvae of the anopheline mosquito that spread malaria. The resulting increase in malaria in counties adjacent to these reservoirs triggered TVA studies to determine what could be done to reduce mosquito populations. One of these was their control by reservoir water-level manipulation. William Penfound and his colleagues at the TVA used their studies of the life histories of common wetland species and their habitat requirements to develop a water management schedule for the reservoirs that minimized the area suitable for mosquito larvae. In these reservoirs, it was possible to increase or reduce water depths to limit the spread and growth of common wetland species. By manipulating water levels to control the distribution of wetland vegetation, TVA biologists Penfound, Hall, and Hess in their pioneering papers demonstrated that their “naturalistic” approach to vegetation management was effective in controlling mosquito populations. It demonstrated, for the first time, that the distribution of wetland vegetation at any time is dependent on recent and current hydrology. However, their work, which was published in obscure journals, was unknown to other ecologists of their generation.
Feminization of the Woods in Tana French’s In the Woods and Dolores Redondo’s El Guardián Invisible
Authors:   Perm State University, Lapina Evgeniia V.
Published: December 2023

The article studies the narrative means of feminizing the image of the woods in two novels, In the Woods by Tana French and El Guardián Invisible by Dolores Redondo. The main approach employed is feminist literary criticism. One of the key concepts is Michel Foucault´s heterotopia. The methodology of analysis involves comparing plot building devices, important motifs, and spatial poetics of the woods in the novels under study. It was revealed that these novels manifest important similarities from the point of view of depicting the woods as femininity-related heterotopia and link its symbolism with the national mythologies of the two cultures, Irish and Basque-Navarran.
The Use of Interjections for the Stylization of Children’s Speech in Works of Fiction (A Case Study of the Novel Room by E. Donoghue
Authors:   Ural Federal University named after the first President of Russia B.N. Yeltsin, Nikolina Natalia N.
Published: December 2023

The article examines the stylization of the speech of a child narrator in E. Donoghue’s novel Room (2010), which is narrated by a five-year-old boy. His speech is stylized as a child's at different language levels. Onomatopoeic interjections are also used for this purpose. They can be set as well as occasionalisms. They are italicized in the text, which emphasizes their uniqueness and vividness. The interjections are divided into semantic groups. The presence of onomatopoeia and interjections in real children's speech makes their use effective for a plausible stylization of the speech of a child narrator.

Authors:   Perm State University, Chagina Anastasia P.
Published: December 2023

The article discusses the role of tango in the novel «Heartbreak Tango» by the Argentinean writer M. Puig. The purpose of the study is to determine how tango manifests itself in the text of the novel and what role it plays in its plot and artistic system. It was revealed that all three elements of tango (music, dance and text) are present in the novel. The significance of the epigraphs is emphasized because the citation of well-known tangos and boleros allows not only to establish intratextual connections, but also brings the author's point of view into the work. It is concluded that the tango, penetrating the text of the work, reveals the inner world of the characters and the author's intention.
Specifity of Translation of Sylvia Plath’s Poem “Tulips” into Russian
Authors:   National Research University «Higher School of Economics», Barinova Ekaterina V.
Published: December 2023

Sylvia Plath’s oeuvre, with the exception of the novel The Bell Jar, is not so well known to the Russian reader, and in this regard, the republication of the collection of her poems in Russian translations is an extremely important event. The article compares the original text of the poem "Tulips" and its translation by Vasily Betaki, published in the Russian edition of Plath’s Collected Poems. This translation is an example of fruitful "cooperation" between the poet and the translator, which has both its own merits and inevitable losses. Losing the precision and conciseness of the original, the translation partly brings the poem closer to the Russian poetic tradition, making it clearer to the Russian-speaking reader.

Published: December 2023

The article presents an analysis of the connection between the “Moscow text” and the image of its hero in works of modern Russian authors: S. Minaev, R. Senchin, D. Glukhovsky, I. Shipnigov. The features of the inhabitant of the capital are revealed thanks to the toponymy of his life. The research characterizes Moscow as the main plot-forming unit that influences on portrait characteristics of the characters. The main goal of the article is to identify the features of creating the image of heroes in the context of an “urban text”.

Authors:   Perm State University, Chagina Anastasia P.
Published: December 2023

The article examines the masculine/feminine dichotomy in the work of the Argentine writer M. Puig. The purpose is to determine how the opposition of Anima and Animus is used in the novels to reveal the characters and its role in internal and external conflicts. It was found that the acceptance or denial of Anima / Animus significantly affects heros’ ability to accept and understand themselves and their relationships with others and the world around them. It is concluded that only the acceptance of Anima and Animus allows the heroes to achieve internal harmony.
Soviet Russia in The Cantos by E. Pound
Authors:   Perm State University, Bratukhina Liudmila V.
Published: December 2023

The article provides the overview of the references to the events of the Russian revolutions of 1917, as well as the personalities of Soviet leaders – Trotsky, Stalin, Lenin – in the cantos of various cycles of the poem The Cantos ("A Draft of 16 Cantos", " A Draft of the Cantos 17-27", "The Pisan Cantos", "Thrones"). E. Pound's appeal to the realities of Soviet Russia is analyzed in the context of his peculiar concept of world history, in which this state is assigned the role of one of the alternatives to the usurious civilization of Modern times. The special role of Lenin is noted, whose work, quoted in Canto LXXIV and Canto C, turns out to be consonant with the reflections of the lyrical hero of the poem. The conclusion is made about the ambiguity of the images of Soviet leaders mentioned in the poem, and about the uniqueness of the interpretation of the Soviet experience of building a new economic system.
Experience of Reconstruction of the History of One Childhood: P. Modiano’s Novel «Dora Bruder»
Authors:   Perm State University, Bazhanov Aleksandr D.
Published: December 2023

The article examines the experience of reconstructing a real fate, undertaken in the novel “Dora Bruder” (1997) by the modern French writer Patrick Modiano. The analysis establishes that the lack of documentary information about the life of a Jewish girl who died during the German occupation is filled in the novel with the help of imagination, references to the author’s existential experience, historical and social contexts, and the childhood memories of other people of those times. It is concluded that the reconstruction of Dora Bruder’s childhood and the circumstances of the death of hers actualizes the themes of personal and national history memory in the works of the writer.
Evaluating the efficiency of metallized siderite concentrate electric melting

The Bakal siderites belong to poor, hard-to-enrich carbonate iron ores. The low content of phosphorus and non-ferrous metals makes siderites a valuable raw material for obtaining highly metallized concentrate suitable for use in steelmaking processes. Reduction of siderites in a rotating furnace at 1300 – 1350 °C followed by magnetic separation of waste rock allows to obtain a concentrate with metallization degree over 90 % and a content of waste rock of about 5 % suitable for steelmaking as raw materials. The purpose of this work is to evaluate the efficiency of the process aimed at obtaining metal from siderite ore including obtaining of highly metallized siderite concentrate in a recovery furnace, as well as its hot loading into ore-thermal furnace and melting process itself. To do this, the electric melting was calculated in the electric ore melting furnace providing for determination of a large number of parameters including the electricity consumption required for melting. As raw materials we used a highly metallized siderite concentrate (φmet = 92.3 %) containing 35 % of waste rock and, for comparison, a briquetted metallized siderite concentrate obtained from a lump concentrate in which a significant amount of waste rock was removed by wet magnetic separation. The results analysis shows that increase in concentrate temperatures from 25 to 1000 °C decreases specific energy consumption and at the same time increases the furnace productivity to values comparable to the parameters of melting briquetted concentrate. This confirms the efficiency of the developed process. To reduce the melting point of high-magnesium slag, it is proposed to use colemanite as flux.

Using the wire-arc additive manufacturing method (WAAM) on a 5083 aluminum alloy substrate, a non-equiatomic Mn – Cr – Fe – Co – Ni high-entropy alloy (HEA) coating was formed. By scanning and transmission electron diffraction microscopy we analyzed the structure, phase and elemental composition of the contact zone after irradiation with high-current low-energy electron beams with the following parameters: accelerated electron energy 18 keV, electron beam energy density 30 J/cm2, electron beam pulse duration 200 µs, number of pulses 3, pulse repetition rate 0.3 s–1. Multiphase multielement submicro- and nanocrystalline structures are formed predominantly in the substrate, which has a lower melting temperature compared to HEAs. Mutual doping of the coating – substrate system occurs in the contact layer, which has sinuous boundaries. The contact layers adjacent to the substrate and coating have the structure of high-speed cellular crystallization. In the layer adjacent to the substrate, the cells are formed by a solid solution of magnesium in aluminum. Interlayers of the second phase, enriched in atoms of the coating and substrate, are revealed along the cell boundaries. In the layer adjacent to the coating, the cells are formed by an alloy of composition 0.17Mg – 20.3Al – 4.3Cr – 16.7Fe – 9.3Co – 49.2Ni corresponding to the coating. Interlayers of the second phase, enriched mainly in magnesium and, to a lesser extent, in atoms of the HEA coating, are located along the cell boundaries. Central region of the contact zone with a thickness of ~1700 μm is formed by lamellar crystallites, which indicates the eutectic nature of its formation. Its main element is aluminum (≈77 at. %).
Lüders and Portevin–Le Chatelier processes in austenitic-martensitic TRIP steel

Published: December 2023

The authors studied the nature of mobile fronts of localized deformation that generate and propagate during deformation of metastable austenitic-martensitic TRIP steel VNS9-Sh along the entire length of the loading curve from the yield point to fracture. A joint research of the nature of the deformation fronts movement and kinetics of the magnetic phase accumulation made it possible to establish that the fronts under consideration are the fronts of the thermoelastic phase transformation of metastable austenite into martensite. This transformation is realized firstly by formation of the Chernov–Lüders bands and then the Portevin–Le Chatelier bands. Both processes are consistent with staging of the deformation curve, which contains a pseudo-plateau, a section with an increasing hardening coefficient, and a section with a decreasing hardening coefficient. It is shown that the deformation-induced phase transformation corresponds to the fronts propagating on the pseudo-plateau and on the section of loading curve with an increasing hardening coefficient. The Portevin–Le Chatelier bands, which are formed in the section of the loading diagram with a decreasing hardening coefficient, are not associated with “austenite-martensite” transformation and have a twin nature. The kinetics of thermoelastic transformation fronts, as well as deformation fronts in materials with a shear mechanism of shaping, can be described in terms of the autowave concept. On the yield plateaus, the phase transformation occurs through generation and propagation of localized plasticity switching autowaves. In the section with an increasing hardening coefficient, it continues through generation and movement of excitation autowaves. The propagation regions of excitation autowaves are limited in the sample space. They are set by the zones of origin and annihilation of primary switching autowaves which were formed on the yield plateau.

Published: December 2023

The technology of plasma surfacing in a protective-alloying nitrogen medium with an additive powder wire is characterized by high productivity and the possibility of alloying the deposited metal. Durability of metal products depends on microstructure, chemical composition, production technology, modes of thermal and surface treatments. The article presents the results of a study of structure and microhardness of the high speed alloy R18Yu deposited in nitrogen medium on medium-carbon steel 30KhGSA. There were no differences in structure of the surfacing layer up to 4 mm in depth, but after four times high-temperature tempering at 580 °C, structural and phase changes were revealed. The values of microhardness after surfacing and tempering are consistent with the literature data.
