Authors: Абусуек Диаля Атия , Никошвили Линда Жановна 
Published: November 2021

В работе проводилось исследование рутений-содержащих катализаторов на основе цеолитов HZSM-5 с различным кремнеземным модулем (40, 80 и 400) в реакции гидрирования левулиновой кислоты (ЛК) до гамма-валеролактона. Была изучена зависимость активности композитов Ru/HZSM-5 от кремнеземного модуля выбранного цеолита и от содержания диоксида рутения на поверхности. Показано, что образец Ru/HZSM-5 с кремнеземным модулем 40 позволяет в достаточно мягких условиях (температура 100С, парциальное давление водорода 1 МПа) достичь 98% конверсии ЛК за 60 мин реакции в водной среде.
In this work, the study of ruthenium-containing catalysts based on zeolites of the HZSM-5 type with different silicate modulus (40, 80 and 400) in the reaction of levulinic acid (LA) hydrogenation to gamma-valerolactone was carried out. The dependence of the activity of Ru/HZSM-5 composites on the silicate modulus of the selected zeolite and on the content of ruthenium dioxide on the surface was studied. It is shown that the Ru/HZSM-5 sample with a silicate modulus equal to 40 allows achieving 98% of LA conversion in 60 minutes of the reaction in an aqueous medium under mild conditions (temperature 100°C, 1 MPa of partial hydrogen pressure).

Нанесенные наноразмерные катализаторы широко используются в различных процессах химической технологии. При этом особые требования предъявляются к носителю, используемому при синтезе катализаторов. Сверхсшитые полимеры являются перспективными носителями, однако зачастую не имеют требуемых свойств (например, кислотности). Для придания дополнительных свойств возможно модифицировать поверхность полимеров различными веществами или функциональными группами. В данной работе проведено исследование способов модификации и веществ-предшественников кремнийсодержащей фазы для модификации поверхности сверхсшитого полистирола диоксидом кремния.
The supported nano-scale catalysts are widely used in different fields of chemical engineering. For the catalysts, the certain requirements are specified fort the catalyst supports. Hypercrosslinked polymers seem to be the prospective materials for the catalyst synthesis. However, polymeric matrices often do not meet some standards for catalyst supports (i.e. polymers are inert materials and do not have the acidic or basic properties). To infuse the additional properties to polymers it is possible to modify its surface with different compounds or functional groups. In this work, the study of the ways for the modification of the surface of hypercrosslinked polystyrene and silica-phase precursors was carried out.

Klaster Industri Budaya sebagai Dasar Manuver Politik Korea Selatan
Authors: Tamba Asinauli 
Published: November 2021

In July 2016, South Korea agreed with its military alliance, the United States to install Terminal High Altitude Area Defense (THAAD) on its territory. This agreement is the embodiment of the interests of the two countries that were integrated. The United States's interests in spreading influence in the East Asian region and South Korea's interests in protecting the country from North Korea's nuclear test practices on the Korean Peninsula. But the THAAD installation was rejected by China, which considers the instrument as the trigger of tensions in the region and hampering China’s dominance. In expressing its disapproval, China imposed economic sanctions by boycott on South Korean-owned cultural industrial products, namely hallyu. In October 2017, South Korea approved China's request to change its THAAD policy through points listed in the Three NOs. The significant changes in South Korean foreign policy are questionable in this study. This study uses the theory of neorealism as a logical thinking and suggests that hallyu as the main reason for the political maneuvering chosen by South Korea as a boycott of China as the main market share of the hallyu has crippled the South Korean economy. South Korea chose a bandwagoning strategy in the midst of threats in order to be able to maintain the production and distribution of cultural products which are currently the main source of foreign exchange for the country. This research uses qualitative research methods with data collection by literature study.

Keywords: South Korea, China, United States, THAAD, Boycott, Cultural Industry, Hallyu.
O Proteu do abuso sob os olhos do Parlamento: verdade dos orçamentos e prestação de contas no Império do Brasil
Authors: Martins Adelino 
Published: November 2021

Este texto propõe-se a explicar porque, no Império do Brasil, não foi criado um Tribunal de Contas e não foram codificadas as leis de contabilidade pública, embora tais matérias tenham sido discutidas no Parlamento desde 1826.
O problema foi abordado no bojo das discussões sobre a verdade dos orçamentos e a análise considerou os pontos de vista de luzias e saquaremas quanto à fiscalização das contas públicas e à divisão de poderes na monarquia. As reformas institucionais do sistema de contabilidade pública e de tomada de contas efetuadas no Império foram analisadas à luz dos debates parlamentares e da bibliografia de apoio. A abordagem foi institucionalista histórica e as fontes investigadas foram os relatórios dos ministros da Fazenda, os anais da Câmara dos Deputados e do Senado, jornais e livros de época.
As ideias de Vieira Souto sobre a moeda e o câmbio no Brasil entre o final do século XIX e o início do século XX
Authors: Cosentino Daniel 
Published: November 2021

Este trabalho tem como objetivo entender as ideias de Vieira Souto sobre moeda e câmbio no Brasil durante a Primeira República. A historiografia dá pouca atenção às ideias econômicas que embasavam o debate entorno das políticas econômicas no período. Para ele, o papel moeda não se relacionava às oscilações do câmbio, mas sim a variações no balanço de transações com o exterior. Assim apresenta uma interpretação da realidade econômica brasileira que permite caracteriza-lo como um precursor do desenvolvimentismo no Brasil.

AN ANALYSIS OF DIRECTIVE SPEECH ACTS PRODUCED BY TEACHERS IN EFL CLASSROOM
Authors: Suryandani Putu Dinia , Budasi I Gede 
Published: November 2021

<p>The teaching and learning process entails several encounters in which the teacher and students exchange a variety of utterances, particularly in language classes. Understanding language involves an understanding of pragmatics. Teaching and learning will be more successful if appropriate speech acts are used. Directive Speech Acts are a type of speech act that is frequently employed in classroom interactions. It is used by the teacher to give instruction, command the students to do something, limit the students’ bad behavior, etc. This study aims at investigating the types of directive speech acts and analyzing the functions of the acts used by English teachers at SMKN 1 Sawan. The theory of directive acts classification adopted in this study is the theory proposed by Ibrahim (1993). Ibrahim’s theory classified directive acts into six major types. They are <em>requestive, question, requirement, prohibitive, permission </em>and<em> advisory</em>. This research also focused on the functions of directive acts based on Amalsaleh, Yamini, and Yarmohammadi's (2004) theory. They are <em>elicitation, instruction, advice, threat, </em>and <em>attention-getter. </em>This research was a descriptive study with two teachers as the subjects of this research. Observation and recording were used as the technique in collecting the data. The validity of the data used is source and theory of triangulation. The results showed that the most frequent type of directive speech acts used by the teachers was <em>question directive</em> with occurance of 185 utterances (46.95%). Teachers that employ the question directive encourage students to be interested in the world around them, to enhance their abilities and attitudes toward science, and to enhance their speech communication and critical thinking. The other functions of the acts were also identified in various types of the acts.</p>

Authors: Herrera Moratta Mario A , Navas Romero Ana Laura , Vento Barbara , Martínez Carretero Eduardo 
Published: November 2021

Introducción y objetivos: Los arbustos de ambientes de alta montaña desempeñan un papel clave en el mantenimiento y el funcionamiento de procesos ecosistémicos. Sin embargo, los estudios para conocer su morfología y su asignación de asimilados son escasos. El objetivo de este trabajo es cuantificar la materia seca y analizar la morfología de Senecio oreophyton y Baccharis tola ssp. tola, en los Andes centrales de Argentina y proponer ecuaciones alométricas.
M&M: El estudio se realizó en la Puna Austral, provincia de San Juan. Se seleccionaron 60 plantas de S. oreophyton y de B. tola. En cada ejemplar se midieron las variables biométricas para estimar la materia seca. Se fotografiaron las vistas lateral y superior para estimar su morfología. Cada ejemplar fue cosechado y diferenciado en tallo, hojas y raíces.
Resultados: La forma geométrica de S. oreophyton fue un cono invertido y de B. tola una semiesfera. En la materia seca de B. tola encontramos valores similares en tallos y hojas, y valores bajos en raíz, mientras que en S. oreophyton la materia seca fue mayor en tallos, siguiendo raíz y luego hojas. Se establecieron ecuaciones alométricas para cada componente a partir de mediciones directas de campo.
Conclusiones: La partición de materia seca encontrada para ambos arbustos indicaría una fuerte asociación de la morfología de la planta y su estrategia para sobrevivir en condiciones de altura. Este trabajo es un aporte al conocimiento sobre las características morfológicas de arbustos leñosos y sus interacciones ambientales para la conservación y manejo de ecosistemas de montaña.

Published: November 2021

Introducción: el archivo histórico Cipriano Rodríguez Santa María de la Universidad de La Sabana cuenta con múltiples recetas médicas empleadas por médicos y boticarios en el Nuevo Reino de Granada. Una de ellas prescribe el cacao para disminuir síntomas generados por afecciones del sistema respiratorio. Objetivos: describir el análisis de una receta médica empleada entre los siglos XVIII y XIX para el tratamiento del ahogo y describir la propiedad fitoterapéutica del cacao conocida gracias a la evidencia científica actual. Materiales y métodos: búsqueda documental en el Archivo Histórico Cipriano Rodríguez Santamaría de la Biblioteca Octavio Arizmendi Posada de la Universidad de La Sabana. Transcripción y análisis del documento denominado “Ahogo” y revisión de la literatura científica actual, así como de los textos originales, sin límite de tiempo. Resultados: la receta médica describe las características del cacao (Theobroma cacao) como agente fitoterapéutico con propiedades antiinflamatorias, analgésicas, antioxidantes e inmunomoduladoras aportadas por componentes como los ácidos oleico, esteárico, palmítico y flavonoides entre otros. La teobromina ejerce efectos broncodilatadores y antitusivos. Conclusiones: el legado histórico colonial conservado en los archivos locales permite comprender racionalmente las propiedades de los agentes herbarios empleados para enfermedades y síntomas asociados. Existe evidencia científica que respalda el uso del cacao para disminuir la sintomatología asociada con el ahogo. Pese a ello, la escasa o nula descripción de la posología y los efectos secundarios, dificulta analizar la eficacia de esta tradición. En consecuencia, no se puede establecer su eficacia científicamente.
VI encuentro nacional de semilleros de investigación en salud
Authors: Gómez López Arley 
Published: November 2021

El origen de la educación universitaria a partir de siete artes liberales reunidas en el Trívium (gramática, dialéctica y retórica) y el Quadrivium (aritmética, geometría, astronomía y música), marcan un cambio generacional irreversible en la edad media. El joven estudiante era formado en el uso del trívium como instrumento para el autoaprendizaje y posteriormente a través del quadrivium profundizaba en el conocimiento de las ciencias y las artes. Bajo este modelo se formaron científicos notables como Nicolás Copérnico, Isaac Newton, Marie Curie, Henri Poincare, Iván Pávlov e Iliá Méchnikov, entre muchos otros. Un elemento común en el proceso educativo de estos investigadores fue la formación y guía recibida en un momento determinante de sus vidas por su mentor; un profesional con experiencia y alta formación, pero ante todo un consejero, capaz de motivar y potenciar con disciplina y constancia las habilidades innatas del joven estudiante por el conocimiento, materializando así sus sueños en un proyecto de vida con vocación de servicio social.

Hardness Measurement of Plastics and Elastomers
Authors: Herrmann K. 
Published: November 2021

Abstract
This chapter reviews the tests and procedures used for measuring hardness of plastics and elastomers. The conventional testing methods (Rockwell, Vickers, Brinell, and Knoop) used for testing of metals are based on the idea that hardness represents the resistance against permanent plastic deformation of the material to be tested. However, elastic deformation must be considered in hardness measurement of elastomers. This chapter discusses the equipment and processes involved in the durometer (Shore) test, the International Rubber Hardness Degree test, and other specialized tests. It presents the criteria that can be used to select a suitable hardness testing method for elastomers or plastics and describes processes involved in specimen preparation and equipment calibration.
