Выполнена корректировка ранее рассмотренного состава порошковой смеси в системе ZrSi2-MoSi2-ZrB2-Si в сторону снижения содержания относительно легкоплавких фаз ZrSi2, MoSi2 и увеличения доли тугоплавкой фазы ZrB2. Сформировано жаростойкое покрытие на C/C-SiC композите методом обжигового наплавления порошковой смеси при температуре 1750oС и давлении разрежения аргона 150-200 Па. Фазовый состав покрытия включает, мол. %: 23.2 ZrSi2, 16.8 MoSi2, 46.0 ZrB2 и 14.0 ZrC. Синтез вторичной фазы ZrC осуществляется in situ в результате реакционного взаимодействия в системе ZrSi2-C. Проведены испытания на стойкость к окислению и абляции в условиях обтекания и нагрева поверхности в интервале 1300-2350wT=oС потоком воздушной плазмы при скорости 4.7-4.8 км/с и энтальпии торможения 48-50 МДж/кг. Показано, что выполненная корректировка состава обеспечила увеличение защитной способности покрытия при 2200wT=oC в 2.5 раза - вплоть до 170 с, а также повышение максимально допустимого уровня рабочих температур с 2200wT= до 2350oC. При этом средние значения удельной потери массы и скорости уноса массы покрытия снизились на 23 и 14% и составили 3.9 мг/см2 и 13.1 мг/(см2·ч) соответственно. Получены оценки для значений константы скорости гетерогенной рекомбинации атомов и ионов воздушной плазмы на поверхности покрытия: 2 1, 5 2, 9 3, 14 3wK=±± ± ± и 19 2± м/с при 1300-1450, 1500-1750, 1800-1950, 2000-2150wT= и 2200-2350oС соответственно. Установлено снижение спектральной излучательной способности покрытия λε от 0.69 0.02± в исходном состоянии до 0.41 0.02± после огневых испытаний в интервале длин волн 600-900λ= нм при комнатной температуре. Показано, что основными факторами, ограничивающими ресурс защитного действия покрытия, являются сквозное окисление матрицы ZrSi2 и испарение модифицированного цирконием боросиликатного стекла, приводящее к увеличению в оксидной пленке доли фазы ZrO2 с высокой анионной проводимостью и каталитической активностью.

Массовое использование композитов в машиностроении, авиакосмической технике, строительстве, расчеты зданий и сооружений с учетом совместной их работы с грунтами оснований, а также расчеты подземных сооружений и горных выработок совместно с вмещающим их массивом горных пород (грунты и горные породы по существу являются композитами природного образования) ставит задачу надежного, быстрого и удобного способа определения механических характеристик таких композитных материалов. В геомеханике определение механических свойств часто длительное по времени и весьма затратно, а иногда их невозможно определить экспериментальным путём (проблема определения характеристик скальных массивов). Таким образом, можно констатировать, что в настоящее время в инженерной и научной деятельности проблема определения эффективных характеристик композитных материалов является актуальной. Цель данной работы показать возможность определения тензора жесткости, используя теоретические методы, решая задачу на ячейке периодичности, а не на представительном элементе объема, при условии соблюдения периодичности расположения центров включений. В работе излагается пять вариантов оценки эффективных характеристик деформационных свойств композитных материалов с периодическим расположением центров включений и случайными значениями их размеров. Показана применимость предложенного вероятностного подхода к определению эффективного тензора жёсткости на ячейке периодичности. Такой подход позволяет получать не только средние значения (эффективный тензор жёсткости), но и три основных центральных момента - со 2-го по 4-й порядок, характеризующие случайную природу эффективного тензора жёсткости. Разработанные в статье подходы к оценке эффективных деформационных характеристик композитных материалов с периодическим расположением центров включений, характеризуемых случайной величиной радиусов могут быть практически распространены и на оценку других физико-механических свойств.

В данной статье исследуются тепловые и волновые эффекты в композиционном материале. Для этого проводится воздействие СВЧ электромагнитного поля на модельную ячейку, которая состоит из внешнего слоя эпоксидной смолы с внутренним сердечником из углеродных или стеклянных волокон. СВЧ воздействие было проведено с помощью установки рупорного типа. Обработка образцов проводилась поочередно, размещение обоих цилиндров относительно рупора осуществлялось аналогичным образом и на одинаковом расстоянии от него. Результатом экспериментальной части работы стали термограммы, полученные с помощью тепловизора в течение всего периода воздействия на образцы. Для характеристики распределения тепловых полей, полученные с помощью термограмм данные, были сведены в таблицу, что позволило эмперически оценить интенсивность нагрева при различных значениях радиуса на торцевых поверхностях образцов. Показано, что СВЧ нагрев образцов идет от центра. Было отмечено, что модельная ячейка с сердечником из углеродных волокон нагревается быстрее и до более высокой температуры. Для учета возможных ситуаций изменения структуры опытных образов около источника тепла, которым являлся стержень из волокон различной природы, (внутренний стержень) нужно рассмотреть трехслойную структуру композитного материала. Такая модель его структуры позволяет задать и исследовать различные условия теплового воздействия, в том числе, воздействие на часть модельного образца. По результатам эксперимента формулируется теоретическая математическая модель, представляющая собой несвязанную задачу термоупругости. Проведены расчеты предложенной математической модели. Получено качественное совпадение с результатами эксперимента.
Livres polyglottes et conflits linguistiques au XVIe siècle : l’exemple de l’occitan
Authors: Jourde Michel
Published: January 2024

La situation linguistique du sud de la France se caractérise au XVIe siècle par l’existence de plusieurs langues auxquelles sont attachées des valeurs fortement différenciées. Quelle relation peut-on établir entre cette situation de conflits linguistiques et le caractère plurilingue de nombreuses publications occitanes de cette période ? En étudiant différents types de dispositifs littéraires et typographiques, on constate que la coprésence des langues peut servir, selon les cas, à masquer ces conflits ou à les exhiber, soit pour en faire la matière d’un jeu littéraire, soit afin de (tenter de) retourner la dynamique de ces conflits au profit de la langue minorée. Ces différentes réalisations ont cependant en commun le désir d’offrir aux lecteurs, dotés de compétences diverses, la représentation d’un monde dans lequel cohabitent des langues dont les valeurs demeurent mobiles.
Médecins, chirurgiens, apothicaires : à qui sont adressées les traductions médicales ? Enquête sur l’édition lyonnaise des années 1540
Authors: Rajchenbach Élise
Published: January 2024

Dans les années 1540, l’édition médicale est en vogue à Lyon, en particulier à travers les traductions de Galien. Or, les préfaces des traductions du médecin grec mettent en lumière les conflits qui sous-tendent pour les médecins, chirurgiens et apothicaires la pratique de leurs domaines voisins. Traduire Galien et ses épigones revient en effet à rendre accessible la science antique, jusqu’alors réservée aux lecteurs de latin, voire de grec, c’est-à-dire aux savants. Nous étudions les enjeux qui président à la diffusion de ces traductions ainsi que les réceptions qu’elles semblent avoir entraînées auprès d’un public plus polymorphe qu’il n’y paraît, dans un contexte plus vaste de réflexion sur le rôle de la traduction comme vecteur de diffusion de savoirs.
Amours privées, amours publiques, amours publiées ; l’inscription de divers cercles publics dans quelques avatars des canzonieri pétrarquistes des années 1570–1580
Authors: Triou Charlotte
Published: January 2024

Cet article propose une lecture des indices qui, dans des recueils imprimés, formulent une adresse à un public restreint et se réfèrent à une circulation préalable des pièces poétiques. Il s’agit d’analyser la tension, du point de vue de la réception par des publics successifs, entre le paradigme de lecture générique du canzoniere et l’inscription dans un contexte éthique et social particulier. Sont ainsi comparés des itinéraires de publication très différents : d’une part, des processus ancrés dans le contexte de la cour royale (Jamyn et Ronsard), et d’autre part, des processus naissant du deuil d’une épouse (Christofle du Pré et Pierre de Brach). Ces recueils qui détournent le cadre énonciatif pétrarquiste et étendent les significations des motifs pétrarquistes permettent d’observer la concurrence entre les attentes herméneutiques liées au genre du canzoniere et celles liées à l’adresse à un lectorat de circonstance.
A Compendium of the Wondrous Deeds of Caterina da Racconigi: Hagiography or Philosophical Treatise?
Authors: Zarri Gabriella
Published: January 2024

Gianfrancesco Pico’s interest in Caterina da Racconigi, a mystic and prophet revered in Piedmont in the first decades of the sixteenth century, was born out of a scientific curiosity prior to becoming devout admiration. The Compendio delle cose mirabili, Gianfrancesco’s last work, written after the completion of his Life of Savonarola, is a continuation of his treatises on prophecy and premonition and on the discernment of spirits and witchcraft; it aims to observe and describe the mystical phenomena attributed to a woman whose conduct is inspired by a specific model of holiness. The Compendio is therefore a composite text, part scientific treatise and part hagiography. This article examines the text in terms of hagiography by relating it to the model of Catherine of Siena and to the lives of the living saints that inspired Caterina da Racconigi’s own behaviour. It also explores the significance of the work within Gianfrancesco’s religious thought.

Published: January 2024

El propósito de las investigaciones compiladas en este libro es observar el efecto de la rentabilidad, la estructura de capital, los precios de las acciones y el flujo de efectivo en la predicción de la condición de dificultades financieras en las empresas manufactureras reportadas en la base de la Superintendencia de Compañías, Valores y Seguros del Ecuador, para la ventana temporal indicada, tanto de forma parcial como simultánea. El desamparo financiero es un proceso en el cual las empresas experimentan dificultades financieras que tienen una relación muy estrecha con el riesgo de quiebra que se presenta en ellas, lo que les impediría cumplir con sus obligaciones. La empresa experimentará estas dificultades si su flujo de efectivo operativo no puede cumplir con las obligaciones a corto plazo, como el pago de intereses sobre préstamos que han vencido. Cuanto mayor sean las obligaciones, mayor será el riesgo de dificultades. 176 páginas ISBN: 978-9942-645-21-0 EISBN: 978-9942-645-22-7

ABSTRACTIVE-BASED AUTOMATIC TEXT SUMMARIZATION ON INDONESIAN NEWS USING GPT-2
Authors: Khasanah Aini Nur , Hayaty Mardhiya
Published: January 2024

Automatic text summarization is challenging research in natural language processing, aims to obtain important information quickly and precisely. There are two main approach techniques for text summary: abstractive and extractive summary. Abstractive Summarization generates new and more natural words, but the difficulty level is higher and more challenging. In previous studies, RNN and its variants are among the most popular Seq2Seq models in text summarization. However, there are still weaknesses in saving memory; gradients are lost in long sentences so resulting in a decrease in lengthy text summaries. This research proposes a Transformer model with an Attention mechanism that can fetch important information, solve parallelization problems, and summarize long texts. The Transformer model we propose is GPT-2. GPT-2 uses decoders to predict the next word using the pre-trained model from w11wo/indo-gpt2-small, implemented on the Indosum Indonesian dataset. Evaluation assessment of the model performance using ROUGE evaluation. The study's results get an average result recall for R-1, R-2, and R-L were 0.61, 0.51, and 0.57, respectively. The summary results can paraphrase sentences, but some still use the original words from the text. Future work increase the amount of data from the dataset to improve the result of more new sentence paraphrases.

Published: January 2024

Student development includes conduct as a key component. Student behavior becomes crucial in deciding how successful students will be in different spheres of life. The variety of student behavior can hinder the learning process and personal development of students. Through the development of an expert system-based counseling model based on backward chaining, this study seeks to discover trends in student behavior. The research process starts with problem analysis, goal setting, literature study, data collection, system design and implementation, and results analysis. It then moves on to counseling model development and implementation in the school setting. To determine the reasons for the unruly behavior of the kids, data were analyzed using a backward chaining methodology. UML Usecase diagrams are used in system design to define the roles of actors and users. The established counseling model, which consists of 14 behaviors, 67 phenomena/symptoms, and 14 rules, focuses on goals and methods to modify student behavior. Three students underwent system testing based on previously achieved goals from therapy. The findings revealed "Smoking," "Emotional Problems," and "Fighting" among the student behaviors. When the Backward Chaining-based counseling model is used, it is simpler for homeroom teachers to gather information about students' conduct from them and to offer remedies based on the transfer of professional knowledge without having to wait for the counselor guidance procedure

OLED technology is widely used in various displays, which operate in a wide range of temperatures. For such devices, it is necessary to maintain the luminance and chromaticity coordinates at the given level when the external temperature changes. In this work, a program was developed that, based on the electro-physical characteristics and electroluminescence spectra of a white OLED sample at different temperatures and currents, as well as the spectral characteristics of the coloured filters, allows for selection of currents in the range of (1–25) mA, applied to each subpixel in such a way as to converge the chromaticity coordinates to the specified values. Various chromaticity coordinates were tested in the process of program execution, including CIE sources of type A, type B, type C, and type D65. In each of these cases, the program significantly reduced the difference in chromaticity coordinate changes with temperature. The obtained results will be used for gamma correction of micro-displays produced at the Cyclone Research Institute during their operation at a wide range of temperatures.

Published: January 2024

In this study, the focus is on the half-siblings relationship formed with the children they have from the marriages of single-parent individuals who have experienced the cycle of remarriage and divorce. In the study, the reasons for having children in the next marriages of single parents and the sibling relationships of half-siblings from the perspective of the parents were discussed. The study is a field research conducted by choosing a qualitative research method for the phenomenon of half-siblings built in line with the marriage-divorce cycle. The universe was reached by snowball-chain sampling within the non-random-purpose sampling. Data were collected using semi-structured interview form, observation and document-document review. The data obtained in the interviews were handled with the descriptive analysis technique and the themes and sub-categories related to the themes were interpreted by forming the data obtained. In the conceptual part of the study, with reference to the existing literature; The marriage divorce cycle and the construction of half-siblings are discussed. In the research findings, it was understood that the idea that the presence of a common child strengthens the marriage is dominant in the step-family structures re-established by the individuals who have experienced the marriage-divorce cycle. After the disintegration of the step-family, the effect of sharing a common residence has been determined to strengthen the fraternal relations of half-siblings.

Acerola has acquired great importance due to its high vitamin C content and its potential for industrialization. However, during its processing, a quantity of waste (seed and bagasse) is generated, mainly from pulp processing. These residues can be used as new sources of food with high added value and contribute positively to the reduction of environmental impacts. Therefore, this research aimed to add value to the acerola by-product through the development of a functional yogurt. To develop this research, a complete 2² Factorial Planning and Response Surface Methodology were used. The planning included five different levels, with three central points totaling seven tests. The independent variables were: concentration of acerola by-product (%) and brown sugar (%). The responses analyzed were: water content (g/100g), acidity (g/100g), pH, ascorbic acid (mg/100g), reducing sugars (g/100g), and ash (g/100g). The Statística 7.0 software was used to analyze the results of the adopted planning. It was observed that the acerola by-product concentration factor had the greatest influence on the vast majority of responses studied.
