Authors: Rosario Luiz Ângelo de Paula , Ferreira Ludimilla da Silveira , Oliveira Ivanir Luiz de
Published: January 2022

RESUMO Os processos de moldagem em areias a verde são mundialmente utilizados na confecção de peças fundidas. Normalmente areias a verde são constituídas de areia de sílica, argila bentonítica, água e aditivos. O uso da bentonita sódica é amplamente difundido pelas suas qualidades superiores como ligantes. As argilas são compostas de argilominerais a base de silicatos hidratados de alumínio que comumente atingem certa plasticidade quando umedecidas. O que diferencia uma argila de outra é o tipo de estrutura e as substituições que podem ocorrer dentro desta estrutura; do alumínio por magnésio ou ferro, e do silício por alumínio ou ferro. Em todo caso o caulim é um mineral industrial importante nos vários mercados mundiais incluindo aplicações em cobertura e carga de papel, cerâmica, tintas, plásticos, borrachas, fibras de vidro e muitas outras utilizações. As misturas apresentam o teor de umidade que variou a relação água/argila de 0,1 a 0,3 para areia aglomerada com 10% de caulim. Para cada ensaio de compactabilidade, permeabilidade e resistência â compressão a verde foram elaborados 3 corpos de prova conforme ABNT com diferente relação areia/argila/água. Como enriquecimento do trabalho, foram avaliadas as propriedades permeáveis da areia sílica utilizada nos ensaios. Conclui-se que o caulim, sem aditivos, oriundo da cidade de Tijucas do Sul (PR), apresenta resistência mecânica â compressão aceitável para a sua utilização em fundição, entretanto, a permeabilidade não foi satisfatória em nenhuma composição. Já a compactabilidade foi aceitável apenas quando a umidade causou o inchamento da areia, sendo que neste ponto, houve também a máxima resistência mecânica à compressão.

RESUMO O elevado consumo de produtos industrializados e o seu rápido descarte produzem grandes quantidades de resíduos sólidos, dos quais, os principais constituintes são os materiais poliméricos. Dentre estes, as borrachas de butadieno estireno merecem destaque. Esse material é usado em diversos setores, entre eles, o alimentício, para produção de chicles. A reciclagem desses materiais deve ser sempre pesquisada, buscando, principalmente, novas aplicações. Assim, este trabalho usou a borracha residual (BP) como matriz para cristais de quartzo. Os materiais preparados foram estudados por diversas técnicas, como, por exemplo, a Análise Termogravimétrica (TGA) e a Espectroscopia no Infravermelho por Transformada de Fourier (FTIR). Além disso, os materiais tiveram suas propriedades elétricas medidas. Foram feitas medidas de capacitância, campo elétrico, resistividade e densidade de corrente. Entre os materiais testados, o compósito carregado com 44,4% de quartzo apresentou a resposta mais linear e mais intensa de variação de carga elétrica em função da pressão aplicada. Portanto, os resultados mostraram que foram obtidos materiais com potencial aplicação no campo de sensores capacitivos de pressão.

RESUMO Este trabalho teve como objetivo quantificar e avaliar através de técnicas de análise e processamento digital de imagens (PDI) defeitos formados em revestimentos metálicos à base de ligas ferro-cromo e ferro-cobalto, obtidas por aspersão térmica à arco elétrico (AT). Imagens obtidas por microscopia óptica (MO) foram processadas e analisadas utilizando-se o software FIJI (Image J) para quantificação de poros, redes de óxidos e trincas. Também foram feitas medidas de microdureza Vickers (HV) e testes de corrosão segundo a norma ASTM-G48. Foram realizados dois testes de corrosão em meio de cloreto férrico: um expondo-se apenas o revestimento, onde a resistência a corrosão foi avaliada qualitativamente através de imagens de MO e a possível presença de pites de corrosão e outro expondo-se o conjunto revestimento e substrato, neste caso, a resistência a corrosão foi avaliada quantitativamente através de medidas na espessura da camada de revestimento antes e depois da exposição. Foi realizada uma avaliação microestrutural por MO e microscopia eletrônica de varredura (MEV). Os resultados obtidos por MO, MEV e microdureza indicaram uniformidade nas camadas depositadas e porcentagem de defeitos variando entre 3,7% e 4,3% para os revestimentos estudados. Todos mostraram possuir excelente resistência à corrosão em meio de cloreto férrico, que é considerado agressivo aos aços inoxidáveis, exceto para a liga de revestimento à base de ferro-cobalto quando encontrou-se combinada ao cobre e com o substrato também exposto ao meio corrosivo
Mechanical and physical characterization of hydroxyapatite/alumina biocomposites produced by the powder metallurgy route for biomedical applications
Authors: Masseli Mayara Ribeiro , Kuffner Bruna Horta Bastos , Vasconcelos Lucas Victor Benjamim , Silva Gilbert , Sachs Daniela
Published: January 2022

ABSTRACT The hydroxyapatite calcium phosphate based ceramic (Hap) is widely used for bone repair, as it is a biocompatible biomaterial and because it has osteoconductive and osteoinductive properties. However, the low mechanical strength of Hap may limit its applicability. Thus, the present work aims to improve the mechanical properties of Hap, associating it with alumina (Al2O3), using the powder metallurgy technique, which consists in the milling of the precursor powders in a planetary ball mill, uniaxial pressing and sintering. The microstructure and mechanical strength of the sintered samples were evaluated using density, microhardness, compressive strength and wettability tests. It was concluded that the use of Al2O3 in the composite improves the mechanical properties of Hap, while decreases its hydrophilic potential. Thus, the composition with 40% Hap / 60% Al2O3 was considered the best for biomedical applications.
Caracterização ótica e microestrutural de filmes finos de MoO3 para aplicação em células solares orgânicas
Authors: Gonçalves Hugo Pedra , Costa Paulo Victor Nogueira da , Ferreira Carlos Luiz , Cruz Leila Rosa de Oliveira
Published: January 2022

RESUMO As células solares orgânicas possuem várias vantagens que as tornam atrativas como baixo custo, flexibilidade, leveza e fabricação via processo rolo-a-rolo. Um dos materiais mais empregados como camada transportadora de buracos nessas células é o polímero PEDOT:PSS. Entretanto, ele degrada muito facilmente em condições ambientais, sendo um dos responsáveis pelo curto tempo de vida desses dispositivos. Esse trabalho teve por objetivo obter filmes de MoO3 para atuarem como camada transportadora de buracos em células solares orgânicas. A técnica utilizada para a deposição dos filmes foi pulverização catódica reativa com rádio frequência e magnetos. O efeito dos parâmetros de deposição, como potência de trabalho e temperatura do substrato, foi investigado. Os resultados de difração de raios x mostraram que os filmes depositados a 200 °C eram amorfos ou nanocristalinos, independentemente da potência de deposição, com exceção daqueles depositados na potência mais baixa, 125 W, que continham uma pequena quantidade da fase β-MoO3. A transmitância desses filmes, medida em um espectrofotômetro na faixa UV-VIS, ficou entre 60 e 75%. Ao contrário da potência de deposição, a temperatura do substrato afetou significativamente as propriedades microestruturais e óticas dos filmes. Os resultados mostraram que filmes depositados acima de 250 °C eram cristalinos e constituídos pelas fases β-MoO3 e α-MoO3, sendo que o percentual da fase α-MoO3 aumentava com a temperatura. As imagens da superfície dos filmes confirmaram o importante papel da temperatura do substrato na cristalização dos filmes, mostrando o incremento da cristalização com o aumento da temperatura do substrato. Os resultados da espectroscopia UV-Vis mostraram que a temperatura de substrato pode ser usada como parâmetro controlador da banda proibida, cujo valor aumentou com a temperatura, de 2,7 eV para 3,1 eV.

Published: January 2022

RESUMO A poluição atmosférica e o aquecimento global são problemas que vêm se agravando ao longo das décadas devido, principalmente, as atividades antrópicas. Os processos de combustão nas indústrias e nos veículos automotores liberam na atmosfera quantidades consideráveis de poluentes gasosos e material particulado. Neste contexto, o presente trabalho buscou avaliar a eficiência do carvão ativado convencional e impregnado com 5% de nióbio na adsorção de monóxido de carbono. Os adsorventes foram caraterizados por análises de espectroscopia no infravermelho por transformada de Fourier - FTIR, microscopia eletrônica de varredura - MEV, adsorção/dessorção de N2 e difratometria de raios X - DRX. Os estudos de adsorção dinâmica foram realizados com massa de adsorvente igual a 3,5 g, em leito fixo com vazão de 500 mL min-1 de mistura de 500 ppm de CO em N2, com sistema de análise gasosa com célula eletroquímica, em temperatura ambiente. Pelos resultados das caracterizações, observou-se que a presença de nióbio na estrutura do adsorvente levou a uma diminuição na área superficial e volume de poros do carvão ativado, porém com um certo aumento das dimensões dos poros observado por MEV. Em relação aos ensaios de adsorção, o resultado de melhor eficiência ocorreu com o adsorvente carvão/5% de nióbio; a presença do metal no material adsorvente resultou em um aumento no teor de oxigênio, favorecendo o processo de adsorção. Os dados experimentais de adsorção em leito fixo, para ambos os adsorventes, obedeceram um modelo de distribuição não-linear sigmoidal de Boltzmann. Pelos resultados dos ensaios de adsorção de CO, pode-se afirmar que os desempenhos dos adsorventes foram eficazes, sendo um processo promissor na minimização de emissões desse poluente.
Produção de concretos autoadensáveis com alto teor de ar incorporado e propriedades mecânicas para fins estruturais
Authors: Ferreira Fernando Mellin Moreira , Castro Alessandra Lorenzetti de
Published: January 2022

RESUMO O uso de concreto autoadensável já é bastante difundido na construção civil, sendo utilizado principalmente em elementos esbeltos e/ou com altas taxas de armadura. Ainda assim, os efeitos combinados de autoadensabilidade com determinadas estratégias modificadoras das propriedades dos concretos são pouco conhecidos. Esse é o caso observado com o aditivo incorporador de ar. Dessa forma, o presente trabalho busca avaliar a influência da incorporação de ar no comportamento de concretos autoadensáveis mantendo propriedades mecânicas adequadas para uso estrutural. Algumas premissas de interesse foram definidas com base na utilização do material para a execução de paredes de concreto moldadas no local. Assim, foram produzidos dois traços de concreto autoadensável, sem incorporação de ar, com classes de resistência C25 e C40 e, a partir de cada um deles, foram produzidos outros dois traços modificados com aditivo incorporador de ar, variando o teor de ar incorporado, em um total de seis misturas cujas propriedades foram avaliadas tanto no estado fresco quanto no estado endurecido. Os resultados obtidos foram muito satisfatórios, considerando que dois dos traços de concreto autoadensável com incorporação de ar apresentaram propriedades mecânicas adequadas para utilização com função estrutural, apesar do alto teor de ar incorporado.

RESUMO Esse trabalho mostra uma rota sintética mediada por tetraetilenoglicol (P. E. 325°C) em que utiliza o ácido túngstico, como material de partida. A formação de uma suspensão estável de cor azul foi observada durante o curso da reação. O tamanho das partículas depende do tempo de síntese, sendo que partículas de tamanho em torno de 400 nm foram obtidas após 15 minutos de reação em tetraetilenoglicol. Os materiais particulados foram então recozidos em diferentes temperaturas: 150°, 350°C, 500°C e 800°C, e caracterizados por TGA / DSC, DRX, FT-RAMAN, MEV, Espectroscopia óptica UV-VIS e adsorção de N2 a 77K. Observou-se que a síntese proporcionou WO3 sob fase ortorrômbica que evoluiu para monoclínica após tratamento térmico na temperatura igual ou superior a 350°C. A caracterização morfológica indicou a formação de partículas ovoides quando tratadas em temperaturas em torno de 500°C, temperatura a partir da qual a área superficial diminui drasticamente. A atividade fotocatalítica para a degradação de rodamina B (rhB, 10 mg.L-1) foi avaliada sob irradiação ultravioleta (6 Watts). Maior atividade foi encontrada para o material tratado a 500°C, sendo que descoramento foi total após 180 minutos na presença de 10 mg desse catalisador.

Published: January 2022

A Educação Física foi inserida no Plano Nacional do Livro Didático (PNLD) em 2019, sendo o manual do professor o modelo de livro adotado. Este artigo analisa a inserção da Educação Física nesse programa e considera o percurso dos livros didáticos nesse componente curricular e o alinhamento dos manuais do professor com as políticas neoliberais de currículo que invadiram o campo da educação brasileira nas últimas décadas. Em um primeiro momento apresentamos o contexto dos livros didáticos de Educação Física no Brasil, desde os guias ginásticos, passando pelos livros didáticos, até os manuais do PNLD, momento em que a Educação Física escolar desperta nova relevância no mercado editorial. Em seguida, realizamos uma análise da coleção de manuais didáticos que obteve a maior quantidade de exemplares vendidos nos anos de 2019 e de 2020, a coleção Práticas Corporais, da Editora Moderna, revelando como ela pode se tomada como um dos indícios das reformas neoliberais de currículo em curso. Por fim, alertamos para a emergência de um sentido de Educação Física escolar moldado pelo mercado e apontamos alternativas para os manuais do professor de forma a escapar da lógica mercadológica vigente.

Published: January 2022

The adoption of recommender systems in online news personalization has made it possible to tailor the news stream to the individual interests of each reader. Previous research on commercial recommender systems has emphasized their use in large‐scale media houses and technology companies, and real‐world experiments indicate substantial improvements of click rates and user satisfaction. It is less understood how smaller media houses are coping with this new technology, how the technology affects their business models, their editorial processes, and their news production in general. Here we report on the experiences from numerous Scandinavian media houses that have experimented with various recommender strategies and streamlined their news production to provide personalized news experiences. In addition to influencing the content and style of news stories and the working environment of journalists, the news recommender systems have been part of a profound digital transformation of the whole media industry. Interestingly, many media houses have found it undesirable to automate the entire recommendation process and look for approaches that combine automatic recommendations with editorial choices.
Modeling in the Process of Verifying a Suspects and a Defendants Alibis
Authors: Stepanenko Diana
Published: January 2022

The author examines the use of modeling in the verification of a suspect’s and a defendant’s alibis. In the conditions of digitization, there are wide prospects for the use of such a method. Alibi verification can be viewed as a special case of the criminalistic reconstruction of the event of the crime, and the modeling method is morphologically included in the process of reconstructing the investigated event or its part. Flowcharts are designed with the use of the working systems of alibi verification proposed by the author, they reflect forensically relevant features of the investigated object that should be selected from the flow of information as information blocks and properly organized. Information blocks are interconnected and correlate with each other. The more content each block contains, the more accurate the result produced by the constructed model will be. The author concludes that modeling should result in building an adequate model of an episode of the criminal event under investigation that will reflect data on the “history” of the alibi and will make it possible to predict its variants.

Authors: Tauseneva Maria
Published: January 2022

The article examines career design as a life scenario for modern youth.
The research material was the results of surveys conducted by centers and companies on career design issues.
The tendencies of career design among modern young people are determined. These include constant development, self-actualisation, individuality, initiative, activity, innovation and technology, design thinking both in career and in personal life, focus on freshness of ideas, own perspective, leadership, overcoming failures, spontaneity and pragmatism, high frequency of transition from one career field to another due to the instability of professional interests. It was revealed that career design is dynamic and has different types of careers; young people are more likely to be guided by the experience of their peers, leaders created their own projects, technology development or world communities, rather than the experience of their parents. It was revealed that remote work, combining remote and offline work, and freelancing are two developing trends in the labor market.

Published: January 2022

Forestry in Irkutsk region features very low efficiency of forest resource exploitation. This works aims to estimate the amount of forest resource in the region, its condition and accessibility. These three data are taken as basis for the method of allowable cut as one of the key forest management tools. The article analyzes the types of lumber in various areas of the region and the dynamics of their exploitation according to the territory zoning, and provides a feasibility assessment of allowable cut development. The statistic reports of the regional Ministry of Timber Complex are used as information resource for the estimated planned and actual lumber exploitation in the forestry areas in seven zones of Irkutsk region. The analysis has revealed an ambiguity in the input data for calculating indicators of standing timber development. According to the study, the input value for logging in some forestry areas is overestimated, which leads to faster forest resource depletion. The authors state that, in the context of increasing the efficiency of forestry, the target indicators of the Timber Complex Development Programme 2019–2024 in Irkutsk region need revision, and the lumber management system requires further improvement.

The objective of this article is to reveal prospective directions for the development of cooperation between Russia and China in tourism business. On the basis of the analysis of the projects in the area of tourism, the authors identified the most prospective projects and drew a conclusion about the necessity of digitalization of the tourism sector to enhance competitiveness of the companies engaged in it, as travel industry has to change its strategies and look for new ways of travelling because of the Coronavirus pandemic. The conducted analysis of the statistical data of 2019–2020 allowed the authors to draw a conclusion that, notwithstanding the new global challenges the tourism faces, the mechanism of business partnership between our countries is constantly improving and cooperation in tourism has become one of the significant factors for the development of strategic partnership between China and Russia.
Problems and Prospects of the Helium Industry in Russia
Authors: Rusetskaya Genrietta , Yuryshev Alexander
Published: January 2022

The transition to an innovative way of development in the gas industry is associated with deep, comprehensive processing of natural gas, the start-up of manufacturing products with high added value. In terms of proven reserves of natural gas, Russia ranks number one in the world, the demand is constantly growing both at the domestic market and for exports. Natural and associated petroleum gases of many oil and gas condensate fields in Russia are multicomponent systems that contain a number of components important for the gas chemical industry (ethane, propane, butane, etc.). The most valuable of these is helium. The purpose of this work is to study the problems and prospects for the development of the helium industry in Russia and in the world. Using the methods of economic analysis, generalization and synthesis, the authors estimated the volume of reserves of helium-saturated gases in the fields of the country and Eastern Siberia, the state of helium production, the potential for using helium in the sectors of the Russian economy, the possibility and conditions of competitive entry into the world market. As a result, they detected Russia’s technological inferiority in a number of industries, coming from the low demand for helium, the location of potential consumers far from production centers, the high cost of helium production, the lack of reliable methods of its transportation, etc. At the same time, full-scale helium demand satisfaction of Russian industries is associated with the construction of the Amur Gas Processing Plant. The demand for helium in the countries of the world is constantly growing, an increase in consumption is observed in traditional industries and in the field of innovative technologies. The US dominance in the production of helium is gradually declining due to the depletion of some deposits. The authors make a conclusion that after 2030 Russia can satisfy domestic consumption of helium to bring the industry to an effective economic and environmental level and, while reducing the cost of production, become a major participant in its world market.
Changes in the Local Territorial Government Organization and Their Effect on Municipal Budgets (by the Example of Trans-Baikal Region)
Authors: Krivonosova Natalia
Published: January 2022

The current reform of local governments in Russia is a process of optimization, consolidation and changing the territorial government organization, which corresponds to global trends in searching for a relevant and effective local territorial governance scheme. The new wave of interest to this process in the RF has been caused by establishing a new type of municipality, namely, municipal district. The article studies the problem of changes in local territorial governance organization in Russia and in Trans-Baikal region, in particular, as well as the effect of these changes on municipal budgets. The analytical calculations are based on the data from The Federal State Statistic Service of RF; the time lag for analyzing the local territorial governance organization is the period of 2007–2020, and 2016–2020 — for analyzing the budget funding of the transformed municipalities in Trans-Baikal region. The results of the study show that the common trends of consolidation of municipalities in Russia became evident only in 2020. According to the analysis of income and expenditures per capita, the territorial transformation of municipality influences the budget relations on the municipal level. Basing on the results of the study, the author proves the necessity of conducting a complex analysis before taking a decision to change a local territorial governance organization in order to build up the financial base of the municipalities.
Changes in the System of Students Life Values in the Russian Far East in the Context of the Covid-19 Pandemic

Published: January 2022

The current historical period of human history is characterized by hard challenges caused by the global COVID-19 pandemic, which inevitably leads to transformations in human consciousness and value-and-meaning sphere. Studies of this aspect are becoming increasingly topical. The article studies the value-and-meaning sphere of full-time students in the context of distance learning and forced isolation. The authors compare the results of two data slices made in 2018–2019 and 2020. The research involved 701 students aged 18–24. The first stage of the research in 2018–2019 academic year involved 295 young people (102 males and 193 females). The second stage was in May 2020 during the lockdown the number of respondents was 406 young people (85 males and 321 females). The authors of the article used E.B. Fantalova’s research conception of the correlation of «value» and «affordability» in various life spheres. The results show a significant difference between students’ pre- and post-pandemic value benchmarks. During the pandemic, we see a pronounced intra-personal conflict between a value and affordability in students’ meaningful life spheres. This gap between a need for achieving internally important values and affordability of this achievement is more significant in relation to an active life style, health, an interesting job, beauty of the nature, arts and freedom. Self-isolation has worsened internal conflicts and the feeling of psychological welfare has faded. The shift in students’ value-and-meaning priorities in the context of the pandemic requires working out new strategies of personal and vocational self-realization, and searching for ways of saving health optimal psychological resources.
Construyendo educación de calidad desde la pedagogía
Authors: Touriñán López José Manuel
Published: January 2022

Construir educación de calidad supone distinguir conceptualmente calidad de la educación y calidad en la educación. Ambos significados convergen en la expresión educación de calidad. El presente trabajo centra su reflexión en el conocimiento de la educación y la actividad común, que es sobre y desde la que se interviene en la relación educativa para lograr educación de calidad. No hay educación de calidad si no se trabaja en la relación educativa, la actividad común. El conocimiento de la educación hace posible la construcción de ámbitos de educación con las áreas culturales, transformando la información en conocimiento y el conocimiento en educación, ajustándolo al significado de educar. Hay que educar ‘con’ el área cultural y esto exige ejercer la función pedagógica con competencia, estableciendo una relación educativa en la que se logre esa educación de calidad. El dominio de la función es lo que hace experto al pedagogo. Y el medio necesario en la relación educativa, para lograr una educación de calidad, es la actividad común interna y externa. Solo por medio de la actividad común se logra la concordancia entre valores educativos y sentimientos que es necesaria para pasar del conocimiento a la acción educativa y, al ajustarse al significado de educar, se hace efectiva la educación de calidad, lo que es valioso en términos de educación.
Estado del arte sobre concepciones de la calidad de la educación superior

Published: January 2022

Dado el carácter polisémico y multidimensional de la noción calidad y de su centralidad y relevancia creciente en la educación superior, resulta necesario sentar bases que permitan conceptualizarla en función de su contexto de aplicación, de modo de dar sustento y consistencia al diseño de políticas focalizadas. El artículo expone los principales lineamientos metodológicos y resultados de una exhaustiva revisión bibliográfica orientada a esos efectos, centrada en la identificación de las concepciones sobre calidad de la educación superior en artículos publicados entre 2016 y 2020 en revistas de alto impacto internacional. Una vez finalizada la revisión, que siguió los lineamientos axiales del método PRISMA-P, quedaron seleccionados 186 artículos del universo inicial de 53 290. Un análisis por codificación abierta deductiva permitió identificar lasconcepciones predominantes de la calidad de la educación superior y sus componentes valorados como sustantivos. Otro de los resultados destacables es la pertinencia de agrupar esas concepciones en dos categorías —“calidad en soi” y “calidad pour soi”—, muy afines con las posiciones asumidas en dos textos muy influyentes en Hispanoamérica. Del análisis de los artículos seleccionados surgió una interrogante crucial: ¿a quién le corresponde determinar la calidad de un producto o servicio en educación superior? La respuesta a esta pregunta dio lugar a la emergencia de un posicionamiento teórico-conceptual alternativo a los subyacentes en esas categorías: “calidad pourqui” (calidad para quién, calidad para quiénes).
La conexión epistémica entre formación humanista y educación profesional universitaria
Authors: Saavedra Campos Martín Alonso , López Pérez Ricardo Arturo
Published: January 2022

La concepción de una formación de carácter humanista ha sido un tema multipresente en la educaciónprofesional universitaria. Tanto en declaraciones institucionales, como en propósitos formativos másparticularizados, aparece con frecuencia la importancia de alcanzar una educación orientada por principios de inspiración humanista. Esto último, con independencia del debate actual referente a las implicancias de una concepción de hombre como entidad superior en el universo. Este artículo examina el asunto de la formación humanista desde una arista poco tematizada, pero a nuestro juicio especialmente relevante: la dimensión epistémica. En ese sentido, aunque se trata el tema a partir de una perspectiva teórica singular, no se pretende presionar en dirección de una lectura hegemónica del Humanismo, en oposición con un enfoque más clásico de orientación valórica. Con estos antecedentes, se plantean tres dominios para enfocar el análisis teórico, que se nombran como: el epistémico práctico, el epistémico disciplinar y el epistémicamente humano. Así, en este trabajo se arguye que una formación profesional con base en un Humanismo contemporáneo, debe contribuir educativamente a desarrollar una comprensión de los problemas epistémicos integrados a la actuación profesional. Esto supone, al menos, una noción amplia de racionalidad, consciente de sus límites y alcances, así como un compromiso con la complejidadinherente de los problemas individuales y sociales; y con el mismo significado de la condición profesional.
Исследование визуального опознания звукоизобразительных слов русского языка на разных стадиях деиконизации
Authors: Ткачева Л.О. , Флаксман М.А. , Седёлкина Ю.Г. , Лавицкая Ю.В. , Наследов А.Д.
Published: January 2022

В статье изложены результаты исследования особенностей визуального опознания русскоязычных звукоизобразительных (ЗИ) слов носителями языка (N = 106) с помощью метода «Методика принятия лексического решения». Каждому испытуемому было предъявлено 128 стимулов, из которых 64 являлись не-словами и 64 — целевыми стимулами. Целевые стимулы в равных частях были представлены нейтральными (не-ЗИ) словами и ЗИ словами (по 32 слова). ЗИ слова были распределены на 4 равные группы (по 8 слов) по принципу снижения степени иконичности, понимаемой как утрата звукоизобразительности в процессе эволюции языка, таким образом, что к 1-й группе относились наиболее явные ЗИ слова, а, соответственно, к 4-й — полностью деиконизированные ЗИ слова. Целевые стимулы представлены односложными низкочастотными словами (от 0.4 imp до 18.3 imp, M = 5.3 imp). В результате исследования были выявлены показатели скорости и точности опознания ЗИ стимулов в зависимости от стадии деиконизации (утраты ЗИ). Обнаружилось, что явные ЗИ слова опознаются медленнее всего и с большим количеством ошибок. Это, по-видимому, связано с тем, что они относятся к классу неизменяемых слов. При этом деиконизированные слова, характеризующиеся всеми признаками знаменательных частей речи, опознаются быстрее, чем не-ЗИ слова. Авторы предполагают, что взаимодействие ЗИ и частеречной принадлежности слова, воспринимаемого визуально, влияет на процесс когнитивной переработки. При этом опознание слова с выраженной ЗИ и сопутствующей «внесистемностью» требует бjль­ших когнитивных ресурсов, чем опознание «системного» и явного ЗИ слова.

Ultrasound is a sound wave with frequencies ranging between 20 kHz and 20 MHz. Ultrasound is able to temporarily and repeatedly open the BBB safely and enhance chemotherapeutic delivery without adverse effects.(Deprez et al., 2021). This novel technique in drug delivery benefits from the powerful ability of ultrasound to produce cavitation activity. Cavitation is the generation and activity of gas-filled bubbles in a medium exposed to ultrasound. As the pressure wave passes through the media, gas bubbles expand at low pressure and contract at high pressure. This leads to oscillation which produces a circulating fluid flow known as microstreaming around the bubble with velocities and shear rates proportional to the amplitude of the oscillation. At high amplitudes the associated shear forces can cut open liposomes (Wanigasekara et al., 2021; Deprez et al., 2021). Vesicles denser than the surrounding liquid are drawn into the shear field surrounding an oscillating bubble. If the shear stress is greater than the strength of the vesicle, it will burst and spill its contents. In a liposome, the vesicle will reform, often at a smaller size than before meeting the shear field. Hence, some interior liquid must be released during the break down. (Pitt et al., 2004) This protocol describes the use of an ultrasound probe to trigger the release of liposomes in glioblastoma cells. This method uses an ultrasound device which is set to the following parameters: Time = 3 min, Pulse = 59 /01, Amplitude = 20%. The ultrasound technique is an easy and reliable technique making it useful in the study of a variety of areas such as oncology. When applied to an ultrasonic transducer, the Pulser part of the instrument generates short, large amplitude electric pulses of controlled energy, which are transformed into short ultrasonic pulses. The VCX 750 is the ultrasonic liquid processor used for this experiment. It is powerful and versatile and can process a wide range of sample types and volumes for many different applications.

Discovered at multiple sclerosis the disturbance of operation of an immune system in many respects are similar to defects at a number classical autoimmune diseases. In the patients with multiple sclerosis are revealed by us the clinical indications close to those at diffuse connective tissue diseases, in particular, at system scleroderma. It was investigated the levels of serum autoantibodies to native and denature DNA in multiple sclerosis and system scleroderma. It was discovered the association of the increased levels of autoantibodies to DNA and the first stage of multiple sclerosis. The data, obtained by us, testify to a generality pathogenesis of multiple sclerosis and autoimmune connective tissue diseases at early stages of their origin with a further divergence of paths of their development.

Objective. To study a wound-healing activity of the earlier synthesized compound-leader sodium 2- (adamantan-1-yl)-2-hydrazino-5-phenyl-4-oxobutenoate (1), as well as to establish the possibility of its practical application in the ointment dosage form.

Materials and methods. The substance-leader 1 was synthesized by the chemical methods described earlier. The experimental 5 % ointment composition based on an aqueous solution of sodium alginate was developed in compliance with the rules for preparing homogeneous ointments. Its effect on the healing of linear aseptic skin wounds in white rats was studied by the method of wound-tensiometry.

Results. The experimental 5 % ointment composition with compound 1 was found to significantly increase the scar tensile strength compared to control without treatment. The developed model ointment showed wound-healing activity comparable to that of the reference drug (Levomekol ointment).

Conclusions. The selected substance-leader 1 in the composition of a model 5 % hydrophilic ointment based on sodium alginate exhibits pronounced biological activity and is a candidate for further research as a potential pharmaceutical substance with complex wound-healing and anti-inflammatory property.

BACKGROUND: The treatment of traumatic and degenerative cartilage damage is one of the largest areas in orthopedic practice, and the therapy success remains limited.
AIM: To analyze the results of surgical treatment of patients with traumatic and degenerative injuries of the knee joint hyaline cartilage using debridement and osteoperforative techniques, taking into account the time from the surgical intervention.
MATERIALS AND METHODS: A statistical analysis was conducted on the treatment outcomes of servicemen with traumatic and degenerative damage in the knee joint articular hyaline cartilage. Patients underwent surgical treatment using osteoperforative techniques (abrasive chondroplasty, tunneling, and microfracturing) at the Clinic of Military Traumatology and Orthopedics of the S.M. Kirov Military Medical Academy from 2009 to 2019. The study relied on the data obtained from questioning the patients using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and LKSS questionnaires.
RESULTS: The result analyses using the KOOS and LKSS scales revealed significantly higher good results in the observed group in the postoperative period from 1 to 4 years than in the groups from 4 to 8 and more than 8 years (p = 0.004). No significant differences were determined in the treatment outcomes of the groups with resection and different osteoperforative methods.
CONCLUSIONS: Treatment methods for hyaline cartilage defects, such as resection and osteoperforative, are technically simple with good treatment outcomes in patients with articular cartilage injuries from 1 to 4 years postoperative. Treatment outcome deterioration was noted in 48 years postoperative, regardless of the treatment method used, which is more significant in patients in 8 years postoperative.
