Szafa z kochankami. Praktyki przesłaniania, odsłaniania i zasłaniania historii Obór w twórczości Mirona Białoszewskiego
Authors:   Instytut Kultury Polskiej, Uniwersytet Warszawski, Miernecka Martyna
Published: February 2023

The aim of this article is to capture one of the unveilings of the history of the manor house in Obory, near Warsaw, and to analyse the principle structuring the essence of transformation of this place in Miron Białoszewski’s work. Using the geocritical method, the author examinesthe relationship between characters and things related to this place selected by Białoszewski and the poetics he used. The frequently recurring motif of the wardrobe was juxtaposed with the analys is of inventories andwills belonging to the owner of the manor at the turn of the 17th and18th centuries, which are preserved in The Central Archivesof Historical Records in Warsaw. The main part of the article is devoted to the aestheticsand functions of 18th-century furniture in relation to the context of thecourt culture of that time, which Białoszewski explored poetically. In his works he played out the tension between the covering and uncovering ofthe secrets hidden in the complicated security systems of baroque furniture.This tension accumulates in the spatial nature of Obory: it is a remoteand hidden place. Its location allowed Białoszewski to practice covering, uncovering and recovering the history of the manor. These practices notonly constituted the structuring principle of the writer’spoetics, but they also open up the possibility of following the transformations of places of such semantic complexity as Obory. They allow us to capture the dynamics of changes that often involve inverting their previous meanings, e.g. in the context of agricultural reform, and also help to expose the related conflicts.
Dom Anny Frank w Amsterdamie – przestrzeń zamknięta jako przestrzeń doświadczeń
Authors:   Wydział Geografii i Studiów Regionalnych, Uniwersytet Warszawski, Korpysz-Wiśniewska Aleksandra
Published: February 2023

The Anne Frank house is a very literal and powerful example of a confined space, where numerous and diverse experiences took place and are still taking place. In the first part of the article the author focuses onthe original experiences of Anne Frank during her time in hiding duringthe Second World War, which were recorded in her diary. Nowadays, thesame building hosts the Anne Frank Museum, which is one of the most popular museums in the Netherlands. The author of this article analyses opinions of visitors published on Trip Advisor and notes that the experience of visiting this museum is connected with various strong emotions. This experience is often considered to be unique and one of a kind. On this basis, she suggests that the Anne Frank Museum, and the Secret Annex in particular, can be considered as an experiencescape.
The science behind the relations among cancer, height, growth patterns, and growth hormone axis
Authors: Boguszewski Cesar Luiz , Boguszewski Margaret Cristina da Silva , de Herder Wouter W
Published: February 2023

The association between growth hormone (GH) and carcinogenesis has long been postulated. The rationale for this association is that several components of the GH axis play an important role in the regulation of cell proliferation, differentiation, apoptosis, and angiogenesis and have been tested as targets for cancer therapy. Epidemiological and clinical studies have examined the association between height, growth patterns, and insulin-like growth factor 1 (IGF1) levels with the most common types of malignancies, while genome-wide association studies have revealed several height-associated genes linked to cancer and/or metastasis-driving pathways. In this context, a permissive role of the GH–IGF signaling system in the link between height and cancer risk has also been investigated. In animal and human models, genetic defects associated with GH deficiency or resistance are associated with protection from tumor development, while the risk of malignancies in acromegaly or in patients exposed to recombinant GH therapy has long been a matter of concern and scrutiny. In this review, we present a narrative and historical review covering the potential relations among height, growth patterns, GH axis, and cancer.
Origins of the Trisagion song in the written sources of the Armenian Church
Authors: Panteleev Sergey
Published: February 2023

One of the issues vigorously discussed by the supporters and opponents of the Council of Chalcedon was that of the Trisagion song text, namely the possibility of using it in the phrase “crucified for us”. During these discussions the question about the circumstances and the time of its origin was also raised. The Armenian literature provides various examples showing who originally used the Trisagion song and when it happened. This article presents a number of extracts from the writings by Catholicos Ovan of Odzoun, vardapet Abraham, Mkhitar Gosh, Grigor of Tatev, Stepanos of Syunik, Armenian theological tradition which are compared with the facts of the Byzantine tradition. Some of the Armenian sources which date the origin of the hymn to the times of Christ obviously have legendary character. Other writings could be correlated with the Byzantine (and other) sources which date the origin of the Trisagion song to the Council of Ephesus (431). None of the Armenian sources, while mentioning the Trisagion song, give any information about the earthquake at the time of St. Proclus of Constantinople when, according to the Orthodox writers, this hymn appeared (or was corrected). However, all the Armenian sources mention the full version of the Trisagion song as the original one, which provides the Armenian theologians with the extra argument for the possibility and necessity of addressing Christ in this hymn.
The relationship between self-attitude and attitude to a “significant person”, a participant in the study process among school teachers in the context of Christian anthropology
Authors: Voronin Sergey
Published: February 2023

In the modern education system, approximately the same processes and mechanisms operate as in the world civilization as a whole. The teacher's love and positive attitude towards the participants of the educational process is both a value and an achievement. Value – because such an attitude towards people within the boundaries of the school environment not only optimizes the educational process, but makes it possible to achieve its main objectives. Achievement – because such an attitude towards the participants of the educational process is possible if a number of conditions are met. One of these conditions is a certain attitude of the teacher to himself. The article analyzes the concepts of relationship and self–relationship, discusses the concepts of "significant other" and concepts close to it - "significant person", "neighbor". The characteristic of the author's position regarding the studied concepts is given. At the same time, this position proceeds from the main provisions of Christian anthropology in the field of attitude towards man (neighbor). The paper formulates a research hypothesis according to which there is a positive relationship between the individual components of the school teacher's self-attitude and the attitude towards a significant person (participant in the educational process). Thus, in the empirical part of the work, the influence of various components of self–attitude on the sensual tone of attitude towards a significant person - a participant in the educational process is investigated. It is important to note that the choice of dependent and independent variables is hypothetical in the study. At the same time, the emphasis on the sensuous tone of the teacher's attitude is dictated by the desire to study the attitude to a significant person-a participant in educational relations in a more non-evaluative aspect. In the process of empirical research, a number of patterns related to the phenomena under study were established, and the interpretation of the results obtained was given.
Teaching Church history in Russian schools
Authors: Stanovskaya Tatiana
Published: February 2023

The article presents some aspects and features of teaching Church history in Russian schools. The first part of the article is devoted to the substantiation of the term "Church History", its relation to history as a science, as well as its place among other fields of sciences. The historical retrospective reveals the emergence and development of the subject of the God's Law in Russian schools and its structure, in which several sections were distinguished, among which were studied: catechism, the doctrine of worship, prayers, Sacred history and Church History, which was considered a continuation and complement of the latter. The main content of the article outlines the purpose, objectives, significance and some methodological features of the study of Church history in the pre-revolutionary period, which were a kind of basis for the development of the study of Church history in modern Orthodox schools in Russia. In the final part, the author gives an overview of the main manuals on Church history in the pre-revolutionary and modern period, identifies modern curricula and other individual aspects directly related to the teaching of Church history in Orthodox schools, such as the psychological and pedagogical characteristics of students studying the section of Church history and interdisciplinary connections. The article concludes with the author's reflections on the further development of teaching Church history in Russian schools.
Metamorphoses of the idea of personality and environment in Russian education: a path to Man
Authors: Litvin Dmitry
Published: February 2023

The article reveals the features of the transformation of the idea of personality in Russian education in a historical retrospective in the context of current social priorities, and also characterizes the dynamics of the role and place of the environment as a pedagogical tool. It is shown that the idea of personality in Russian education came out of Christianity and was influenced by free pedagogy at the beginning of the 20th century. In the future, this idea is subjected to severe ideological censorship. It is established that today the main challenge for education is the "social horizon of artificial values", simulacra (according to J. Baudrillard). The images of a person, which, in the spirit of the People's Commissariat of Education, Socialist Education and Proletkult, are purposefully formed by the media and network communication, are the result of manipulation of a person's emotions and his motivation. The complexity and uniqueness of the individual is lost. It is assumed that education should respond to this challenge by generating and implementing clear authentic goals for the de-velopment of the individual. The experience of history shows the possibility of embedding external utilitarian goals in education, but they are not effective in the context of the true development of the individual. Receiving today a social order for a unique and inimitable personality, the education system is untenable when traditional imperative education is used. The type of personality and its unification is opposed by the complexity of personality and its diversity. The paper traces the idea that the attitude towards the environment and its place in education is undergoing significant changes. The features of the use of personality-developing environmental tools are also different. The educa-tional environment, by definition, is intended to create opportunities for a person who exists exclusively in the modality of the possible (according to D.A. Leontiev). The educational environment acquires a qualitative difference when these possibilities are refracted through the personal principle, realizing a special way of human existence associated with personal functions.

OBJECTIVES

To examine how outpatient mental health (MH) follow-up after a pediatric MH emergency department (ED) discharge varies by patient characteristics and to evaluate the association between timely follow-up and return encounters.

METHODS

We conducted a retrospective study of 28 551 children aged 6 to 17 years with MH ED discharges from January 2018 to June 2019, using the IBM Watson MarketScan Medicaid database. Odds of nonemergent outpatient follow-up, adjusted for sociodemographic and clinical characteristics, were estimated using logistic regression. Cox proportional hazard models were used to evaluate the association between timely follow-up and risk of return MH acute care encounters (ED visits and hospitalizations).

RESULTS

Following MH ED discharge, 31.2% and 55.8% of children had an outpatient MH visit within 7 and 30 days, respectively. The return rate was 26.5% within 6 months. Compared with children with no past-year outpatient MH visits, those with ≥14 past-year MH visits had 9.53 odds of accessing follow-up care within 30 days (95% confidence interval [CI], 8.75-10.38). Timely follow-up within 30 days was associated with a 26% decreased risk of return within 5 days of the index ED discharge (hazard ratio, 0.74; 95% CI, 0.63-0.91), followed by an increased risk of return thereafter.

CONCLUSIONS

Connection to outpatient care within 7 and 30 days of a MH ED discharge remains poor, and children without prior MH outpatient care are at highest risk for poor access to care. Interventions to link to outpatient MH care should prioritize follow-up within 5 days of an MH ED discharge.
Комплекс тимчасових польових укріплень періоду російсько-турецької війни 1735–1739 років на території Нижнього Присамар’я
Authors: Філімонов Дмитро
Published: February 2023

У статті розглядаються польові військово-інженерні споруди, побудовані в період російсько-турецької війни 1735–1739 рр. на території Нижнього Присамар’я. Метою дослідження є вивчення питань, пов’язаних з процесами будівництва та функціонування цих об’єктів тимчасової фортифікації.

Визначено, що виникнення комплексу оборонних споруд на теренах Нижнього Присамар’я відноситься до часу походу Дніпровської армії проти Кримського ханства, здійсненого в 1736 році. Встановлено, що їхнє основне призначення полягало в забезпеченні постачання армії та підтримці її комунікаційного сполучення з ретраншементом Царичанським та Українською лінією. Після закінчення походу нижньосамарські укріплення використовувалися як передові форпости на кордоні. Також показано, що починаючи з 1737 р., коли основні військові дії було перенесено на Правобережжя, а комунікаційним шляхом постачання армії замість сухопутних доріг стала р. Дніпро. Більшість фортифікаційних споруд, побудованих у пониззі р. Самара під час Кримського походу 1736 р., втратили своє первинне значення і були або залишені, або в них утримувалися незначні за чисельністю гарнізони. Виключенням став ретраншемент Усть-Самарський, який, завдяки вигідному розташуванню перед порогами р. Дніпро, використовувалося для потреб Дніпровської флотилії.

La formación de un hispanista de Harvard: Henry Wadsworth Longfellow y George Ticknor, discípulo y mentor
Authors: Basbanes Nicholas A.
Published: February 2023

Este ensayo estudia el papel que George Ticknor (1791-1891), pionero del hispanismo americano y autor de la obra clásica History of Spanish Literature (1849), desempeñó como mentor y guía intelectual de Henry Wadsworth Longfellow (1807-1882), la persona seleccionada en 1836 para sucederlo como Smith Professor de Lenguas y Literaturas Europeas en Harvard. Longfellow es recordado como un poeta de renombre internacional cuyas obras serían ampliamente traducidas y admiradas durante la mayor parte del siglo XIX, pero antes de alcanzar reconocimiento por clásicos como Evangeline, a tale of Acadie y The Song of Hiawatha, dedicó veinticinco años a la enseñanza y traducción de obras europeas al inglés, siendo el español —“la lengua de Cervantes”, como decía— una de sus especialidades. El tiempo que Longfellow pasó en Europa como joven estudioso instruyéndose en aquello para lo que había sido designado a enseñar, incluido, y en particular, un interludio de transición prolongado en España, fue clave para la persona en la que se convertiría y los valores que adoptaría.
Alianzas religiosas pragmáticas y estratégicas en tiempo de pluralización, el caso del Perú
Authors: Lecaros Veronique
Published: February 2023

Según Peter Berger, la pluralización debe ser considerada el nuevo paradigma para abordar los estudios religiosos en el mundo. A pesar del consenso que existe entre especialistas con respecto a la noción de pluralización, queda por entender su significado en clave latinoamericana. Nuestro artículo se enfoca en el campo religioso peruano. Recientemente, las ofertas religiosas se han multiplicado. Hoy, el campo religioso peruano mayoritariamente cristiano, se caracteriza por la todavía preeminencia del catolicismo, la creciente influencia de los evangélicos y el aumento de desafiliados entre los cuales muchos siguen vinculados a la nebulosa evangélica. Sin embargo, la pluralización no se limita a una variedad de propuestas religiosas al alcance de todos, lo cual sería una mera pluralidad, sino que también implica un entreteje de relaciones y alianzas dinámicas interinstitucionales y extra-institucionales. La rapidez de la recomposición creativa caracteriza la evolución actual; sin embargo, la lógica del cambio religioso no es homogénea. Se trata de una pluralización de la pluralización. En el caso del catolicismo popular, la configuración inicial juega un papel determinante; las devociones, de fragmentadas se han vuelto más estructuradas a partir de una recomposición a nivel nacional. En la institución católica se repercuten las disensiones mundiales, entre las corrientes conservadoras y liberales que corresponden principalmente a diferencias de prioridades. Las iglesias evangélicas cuya diversidad esconde una relativa uniformidad siguen muy influenciadas por las corrientes internacionales, en su búsqueda de crecimiento y actualmente de influencia política. Entre las entidades católicas y evangélicas se tejen compromisos y alianzas. Las actividades oficiales corresponden a los acuerdos internacionales ecuménicos e involucran principalmente al ala liberal católico y a las iglesias evangélicas más cercanas al protestantismo tradicional. Por otro lado, se forman plataformas coyunturales comunes marcadas por la agenda familiar y moral que se plasman en marchas multitudinarias articuladas a proyectos políticos neoliberales.
Pluralismo pentecostal na periferia de São Paulo. Estudo do bairro de Perus
Authors: Rivera Dario Paulo , Fajardo Maxwell
Published: February 2023

O artigo estuda a pluralidade pentecostal existente na periferia urbana da cidade de São Paulo. Os estudos sobre o pentecostalismo na América Latina de modo geral enfatizam sua forte presença entre a população mais pobre que vive nas regiões periféricas dos centros urbanos. Ao mesmo tempo, a maior parte desses estudos pressupõem que o pentecostalismo é mais homogêneo do que diverso. Este estudo visa mostrar uma hipótese inversa, ou seja, a diversidade de denominações pentecostais na periferia urbana da cidade de São Paulo. Para isso, o texto analisa inicialmente a problemática relação entre o centro e a periferia historicamente construída nos grandes centros urbanos da América Latina, com foco particular na cidade de São Paulo. Os centros urbanos foram estabelecidos ao longo do século XX seguindo os diversos ritmos de industrialização. Para explicar a periferia urbana de uma cidade como São Paulo, uma das mais industrializadas da América Latina, atentamos para o fenômeno da migração decorrente do crescimento industrial.
A partir dessa análise, buscamos uma definição do conceito de “periferia”, apoiada na rica literatura sobre periferia urbana das áreas da sociologia urbana e da antropologia urbana da cidade de São Paulo. Em seguida, são analisados os dados de uma investigação etnográfica realizada no bairro de Perus, localizado na região noroeste de São Paulo. A etnografia foi realizada em um minucioso trabalho de campo que catalogou a totalidade das igrejas pentecostais, sua denominação, suas dimensões, características básicas e sua localização. Entre os cerca de 70.000 habitantes do bairro, foram encontradas 164 igrejas pentecostais de 60 denominações diferentes. Com base nos dados catalogados dessas igrejas e seus diferentes padrões de distribuição no bairro, discute-se como o pentecostalismo presente na periferia urbana dessa cidade não apresenta uma tendência à uniformidade, pressuposto comum dos estudos que abordam os números do crescimento pentecostal nas últimas décadas. Ao contrário, verifica-se que o bairro estudado abriga uma importante diversidade de igrejas pentecostais.
Perseguidos por la fe. Un panorama en el contexto colombiano sobre el cristianismo no católico (2004-2018)
Authors: Sanabria Madero Sandra
Published: February 2023

En nuestros días, la persecución a la fe cristiana se asocia a países con dictaduras totalitaristas o regímenes islámicos. Existe la creencia de que en países mayoritariamente católicos las corrientes cristianas no católicas deberían ser aceptadas debido a la proximidad de sus creencias. No obstante, la persecución cristiana se da en naciones como México y Colombia. Por ejemplo, en la Lista Mundial de Persecución del 2019 Colombia ocupó el puesto 47 de los 50 países con mayor persecución por la fe cristiana.
En Colombia, esta persecución se presentó desde el siglo xix con la instauración y expansión de las diferentes formas de creer y practicar la fe cristiana por sus congéneres católicos romanos. Para un análisis más actual de esta persecución en el país, se tomó el marco temporal 2004-2018 de la Fundación Visión Ágape que acompaña a los perseguidos por la fe cristiana. Con dicha información se crearon categorías para lograr una sistematización de la información y conseguir un análisis cuantitativo de este fenómeno.
Esta metodología evidenció que los mayores perseguidores del cristianismo no católico en este marco temporal fueron grupos armados ilegales y líderes étnicos, porque ven en el habitus del creyente, en términos de Bourdieu, una amenaza a sus intereses. La persecución religiosa es una acción violenta que se da porque las prácticas del creyente afectan el poder que ciertos actores ejercen sobre una población y un territorio. En definitiva, es relevante esta investigación debido a la escasa bibliografía sobre este tema en Colombia, pues se desconoce la existencia de este fenómeno, aún entre los mismos creyentes.
Intervenciones nutricionales en la mejora de la cultura alimenticia y sostenibilidad en hondureños de primer año universitario
Authors: Pierre Enriquez Jean , Hernandez Santana Adriana
Published: February 2023

Objetivo Evaluar el efecto de intervenciones educativas en la mejora de hábitos alimenticos y adherencia a una dieta saludable y sostenible (dieta mediterránea) en universitarios hondureños en época de COVID-19. La emancipación del hogar ocasiona que los estudiantes universitarios se enfrenten a un nuevo entorno para la planificación de su alimentación durante la transición a su vida universitaria.
Métodos Se realizó un estudio observacional de cohorte descriptivo transversal entre febrero y junio 2020. Los datos presentados se derivan de encuestas de conductas alimenticias y adherencia a la dieta mediterránea (DM) antes y después de intervenciones educativas nutricionales.
Resultados El grupo con intervenciones mejoró sus conductas alimenticias pasando de poco saludables (media: 14,4) a moderadamente saludables (media: 17,3); de igual forma sucedió en la adherencia a la DM, pasando de baja adherencia (media: 7,6) a adherencia media (media: 8,3). En el grupo control no cambió su adherencia, manteniéndose en baja adherencia; tampoco cambiaron sus hábitos alimenticios, manteniéndose en hábitos poco saludables (p=0,068).
Conclusiones Existe evidencia de que el patrón dietético mediterráneo puede ser una opción para reducir los problemas de salud, especialmente, en la época de pandemia, por lo cual esta investigación expuso que un patrón alimenticio mediterráneo puede coexistir en un ambiente latinoamericano una vez que se conocen sus beneficios.
Especies de Colletotrichum asociados a la antracnosis en naranja (Citrus sinensis (L.) Osb.) y su control in vitro con fungicidas
Authors: Guillén-Carvajal María José , Umaña-Rojas Gerardina , Varela-Benavides Ingrid
Published: February 2023

Introducción. El cultivo de naranja (Citrus sinensis (L.) Osb.) es uno de los de mayor importancia a nivel mundial. Dentro de las principales limitantes en su producción está la caída de flores ocasionada por Colletotrichum. Objetivo. Determinar las especies de Colletotrichum asociadas a la antracnosis en naranja y estimar la efectividad in vitro de cuatro fungicidas sobre su control. Materiales y métodos. Este estudio se llevó a cabo entre junio del 2021 y febrero del 2022. Seis aislamientos de hongos, obtenidos de tejidos florales de naranja, fueron identificados vía reacción en cadena de la polimerasa (PCR). Se evaluó la eficacia de los fungicidas tebuconazol, pyraclostrobin, difenoconazol y ferbam sobre dos aislamientos de Colletotrichum. Se realizaron dos ensayos para determinar el grado de inhibición del crecimiento micelial y el porcentaje de efectividad de cada fungicida. Resultados. Colletotrichum abscissum se identificó en pétalos con síntomas y Colletotrichum gloeosporioides en cálices. Se verificó la efectividad de la dosis empleada de los fungicidas tebuconazol y difenoconazol, al presentar inhibición del crecimiento micelial a partir de la décima parte de la dosis comercial evaluada. El pyraclostrobin demostró poco control sobre ambos aislados. El ferbam no presentó un control eficiente en ninguna de las dosis evaluadas en ambas cepas. Conclusión. Los hongos asociados a la antracnosis en naranja, en la finca estudiada, fueron C. abscissum, presente en pétalos con síntomas iniciales y avanzados, y C. gloeosporioides presente en cálices persistentes. La efectividad de los fungicidas evaluados fue mayor para los triazoles, tebuconazol y difenoconazol, en ese orden. El pyraclostrobin evidenció un control deficiente sobre ambos aislados. El ferbam resultó poco eficaz en las pruebas in vitro.

Published: February 2023

We provide extensive surveys in eight estuaries along the coast of Ceará State in Northeastern Brazil, including local samples and data compiled from online data bases and literature. Samplings resulted in a checklist of the estuarine fish fauna, which recorded 126 fish species, and provides original information of some estuaries. Most of the sampled marine species are widely distributed and many are important commercial species for the artisanal fisheries. The addition of records from existing inventories and online collections increases the number of species to 245, of which 11 are threatened (critically endangered or vulnerable) and six are introduced. Our study provides an updated list of fish species of the estuaries along the semiarid coast of Brazil and is intended as a subsidy for further research, conservation and management efforts.
Chronic heart failure following hemorrhagic myocardial infarction: mechanism, treatment and outlook
Authors: Chan Shing Fai , Vora Keyur , Dharmakumar Rohan
Published: February 2023

Myocardial infarction (MI), the blockage of arterial blood supply of the heart, is among the most common causes of death worldwide. Even when patients receive immediate treatment by re-opening blocked arteries, they often develop chronic heart failure (CHF) in the aftermath of MI events. Yet, the factors that contribute to the development of MI-associated CHF are poorly understood. In our recent study (Nat Commun 13:6394), we link intramyocardial hemorrhage, an injury which can occur during reperfusion of areas affected by MI, to an increased risk of CHF. Mechanistically, our data suggest that an iron-induced adverse cascade of events after hemorrhagic MI drives fatty degeneration of infarcted tissue, which ultimately contributes to negative cardiac remodeling. In this Microreview, we discuss the implica-tions of our findings regarding the molecular mechanism, more targeted treatment options as well as perspectives in the clinical care of CHF after hemorrhagic MI.
Image-aided physical and compression characterisation of expanded polystyrene geofoam
Authors: Sreekantan P. G. , Vangla P. , Ramana G. V.
Published: February 2023

The present study focuses on an advanced and accurate characterisation of the compressive behaviour of expanded polystyrene (EPS) geofoam with the aid of imaging techniques. To this end, four types of EPS geofoam with nominal densities varying from 15 kg/m3 to 30 kg/m3 are used. Initially, a detailed physical characterisation is carried out including image-based microstructural quantification (cell size, void fraction, population density), homogeneity using ultrasonic pulse velocity and apparent density. Insights into the compression behaviour of the geofoams, including true strains and failure patterns, are further gathered through full-field strain behaviour in the block using two-dimensional image correlation analysis. For the first time, the effect of nominal densities on the Poisson's ratio of geofoam is also studied through image analysis. The study reveals that compressive response is significantly influenced by homogeneity, which is manifested by the changes in microstructure and apparent density of the geofoam. Furthermore, the image analysis provides insights into the development of failure patterns and strain localisation and their dependency on density, comprehending the geofoam's complex behaviour. Predictions of compressive response based on apparent density and non-destructive tests are developed. The study further recommends safety factors for determining permissible and yield stresses based on statistical analysis.
Effect of a soluble subgrade on leakage through a geomembrane defect
Authors: Fan J. , Rowe R. K.
Published: February 2023

Leakage and erosion of a soluble subgrade overlain by a geomembrane with a 70-mm-long slit defect is examined. The subgrade (gypsum) solubility and its rate of dissolution from a solid state in contact with various solutions are investigated. In the absence of flow, the rate of dissolution is negligible. However, when there is flow there is dissolution, and if the flow is high enough, erosion. Erosion greatly increases fluid migration. The presence of an interface between the subgrade and a dissimilar material (e.g. a geomembrane) facilitates flow, dissolution, and erosion as the interface becomes an ever increasing preferential flow path, leading to a much greater leakage and erosion feature. The findings from this study highlight the risk of having a soluble subgrade below a single geomembrane used alone and exposed for the containment of liquids.
Stem configurations, lexical items, and phonological words in Maltese
Authors: Puech Gilbert
Published: February 2023

Maltese is the 'national' language of the people in the sister-islands of Malta and Gozo. Originally Arabic, Maltese vocabulary has been massively expanded by borrowings from Romance (Sicilian/Italian), and more recently English. Influential contributions in (post)generative phonology and Optimality Theory claim that Maltese phonology is based on the interaction of (Palestinian Arabic type) stress assignment with syncope, and cyclic application of rules/constraints. This approach fails in some cases for Arabic Maltese, and is inoperative for borrowed vocabulary. I argue for distributing morphological constituents in three domains. The stem-domain heads a radical base, to which a preformative morph may be incorporated, and inflectional circumfixes. The Lexical-item domain heads the stem-node to which (in)direct pronominal objects may be concatenated. Clitics are adjoined to the phonological-word domain. All exponents are mapped on the linearized segmental tier. Trochaic stems satisfying morpho-lexical constraints are built in a pre-lexical phase. Vocalism is underlyingly specified or assigned by default, including ‘reverse-imāla’. In a lexical phase, OCP and Licensing shape syllabic stem-profiles to satisfy morpho-prosodic constraints. In the post-lexical phase, surface forms are generated by application of phonological processes: stress assignment, vowel length and quality, voice alteration in obstruents. A model of 'Weak CV Phonology', distantly related to Strict CV Phonology, is drawn up. Segmental representations are analyzed in monovalent elements. Maltese has often been presented as a 'mixed' language with two strata of vocabulary and two morphologies: root-and-pattern, non-concatenative for template-bound vocabulary, concatenative for loan-words. I claim that Maltese consistently requires templatic, concatenative and word-based morphology.

The results of a study of the evolution of the dislocation structure of polycrystals of homogeneous solid solutions in low-stability states in Cu-Mn-based alloys with a FCC crystal lattice are presented. It is found that each stage is characterized by its own deformation carrier in the form of a certain dislocation substructure (DSS), the volume fraction of which has a maximum at this stage. At the same time, at the considered stage, the carrier of deformation of the previous stage gradually disappears as the degree of deformation (ε) increases, however, a carrier of deformation of the subsequent stage appears. In a certain range of values of ε, deformation carriers characteristic of the previous, considered and subsequent stages simultaneously coexist. It is shown that transitions from some types of DSS to other types occur in some intervals of values of the degree of deformation ε. It is discovered that each stage of deformation has its own DSS - carriers of deformation. The transition from stage to stage is accompanied by the formation of new deformation carriers, which is a characteristic feature of weakly stable states of the system. Naturally, the described picture is observed because the study is carried out at such a grain size, which suggests the possibility of implementing a low-stability structural-phase state of the alloy, since the grain size acts in this case as a kind of control parameter.

Using X-ray diffraction analysis, the effect of Ar+ ions with an energy of 15-20 keV (at ion current densities of 100-300 μA/cm2) on the microstructure, the level of internal microstresses and the texture of cold rolled ribbons of alloy Ni-13.9 wt.% W was studied. It was found that short-term irradiation of 80 μm thick ribbons with a fluence of 3.1·1016 cm-2 (for 50 s) at temperatures T ≤ 370°C and T = 630°C leads to a decrease in microstresses in their entire volume, but at the same time the original texture is retained. With an increase in the fluence to 9.7·1017 cm-2 at T = 630°C, the texture also changes from (220) to (200). Changes in microstresses and texture on the irradiated and unirradiated sides of 80-μm-thick ribbons are comparable to each other, despite the fact that the projective range of Ar+ ions with an energy of 15-20 keV in the alloy is only ~7 nm. It is known that annealing in an oven (700°C, 30 min) of such ribbons does not lead to their recrystallization. At 850°C, microstresses are relieved and the texture drastically changed from (220) to (200) both as a result of annealing in a furnace (15 s) and as a result of irradiation with a fluence of 3.2·1016 cm-2 for 17 s, but the effect removal of stresses in the course of furnace annealing is 3 times lower than in the course of irradiation. Thus, the following facts have been established: 1) the occurrence of recrystallization processes in the alloy under study during irradiation at a temperature lower than the temperature of the onset of thermally activated recrystallization and 2) a higher rate of microstresses drop (and to lower values) in the course of irradiation than during furnace annealing. This indicates a significant role of nanoscale radiation-dynamic effects at the cascade-forming irradiation of metastable media.

The paper investigates the characteristics of a pulsed arc discharge of low (≈ 1 Pa) pressure with thermal emission and hollow cathodes in an argon atmosphere. It is shown that a pulsed discharge is stably initiated in an extended, 1.2 m long and 0.6 m in diameter, hollow anode with a volume of about 0.3 m3 at increased (100-300) V combustion voltages and allows reaching currents up to 800 A with a pulsed with a capacity of up to several tens of kilowatts. An increase in the combustion voltage of the discharge from 100 to 300 V leads to a decrease in the inhomogeneity of the plasma concentration distribution over the height of the hollow anode by more than an order of magnitude. An increase in the value of the induction of the axial magnetic field due to an increase in the magnetic coil current from 0.2 to 2 A leads to an increase in the non-self-sustained arc discharge current by 20% at an increased (300 V) discharge voltage.

The problem of the motion of a helium atom inside a fullerene molecule at ultralow temperatures is considered. The solution of the Schrödinger equation is obtained using special functions and numerical methods. The potential energy of interaction of a fullerene particle with a helium atom is calculated by integrating the modified Lennard-Jones potential over the idealized surface of a hollow nanoparticle. As a result of calculations, the regions of the most probable localization of an atomic particle in the n, m, kn state inside the C60 fullerene were found and visualized.

Published: February 2023

The quantum states of the Kapitza pendulum are investigated within the framework of the effective potential obtained by the method of averaging over fast oscillations. An analytical estimate of the energy spectrum of stabilized states is given using a model potential. For the lowest states of the inverted pendulum, an expression is obtained for the spectrum in the form of the energies of a harmonic oscillator, refined according to the perturbation theory. Tunneling corrections to the energies of resonance states in two wells of the effective potential are found. The results of calculations of the structure of vibrational and rotational spectra of the Kapitza pendulum by the semiclassical method and by Numerov’s numerical algorithm are compared.

Authors:   National Research Tomsk Polytechnic University, Lebedev S.M.
Published: February 2023

Thermophysical and dielectric properties of polymer composites based on linear low density polyethylene (LLDPE) and poly(lactic acid) (PLA) filled with hexagonal boron nitride (hBN) have been studied. It is found that all developed composites possess dielectric properties and enhancement thermal conductivity compared with neat polymer matrices. Unlike carbonaceous fillers (carbon black, graphite, graphene, carbon nanotubes), hBN is a good insulator and therefore is more applicable as a filler for heat-releasing materials with purely white appearance. At the same time, both LLDPE/hBN and PLA/hBN composites at 40 wt% filler content possess comparable thermal conductivity about 0.7 W×m-1×K-1, which is almost 95% and 250% higher than those for the neat LLDPE and PLA, respectively.

The paper studies the kinetics of macroscopic localization of plastic deformation in a bimetal obtained by electron-beam surfacing of wire from low-carbon steel 09G2S on a substrate of St.3. Mechanical tests according to the scheme of uniaxial tension of flat ones were carried out at a constant rate at room temperature. The mechanical properties and stages of the plastic flow of the bimetal are compared with those of the starting materials. The kinetics of plastic deformation localization zones in different bimetal layers was studied by digital speckle photography.

This work is devoted to a theoretical study of the structural and vibrational characteristics of a two-dimensional film of an alkali metal (Li, Na, K) deposited on an unreconstructed and reconstructed Cu (110) surface. Calculations were made of the equilibrium atomic configuration, polarization vectors of localized vibrational modes, and the local density of vibrational states for different degrees of adsorption of an alkali metal. All calculations were performed using interatomic potentials obtained using the embedded atom method. The obtained numerical values of the structural parameters, frequency and polarization of localized modes are in agreement with the available experimental data.
