Authors: Evdokimov Dmitry S. , Boldueva Svetlana A. , Feoktistova Valeria S. , Ermolov Sergey Y.
Published: May 2023

BACKGROUND: The pathophysiological mechanisms underlying takotsubo syndrome are still being actively investigated, but it is generally accepted that sympathetic nervous system hyperactivity is of key importance. The method for assessing heart rate variability allows to study the vegetative status of a patient, however, there are few scientific works on this topic at present, and the results obtained are ambiguous.
AIM: To study heart rate variability in patients with takotsubo syndrome in acute and late periods of the disease at rest, when performing vegetative tests (the deep-breath test, active orthostatic test), as well as before and after mental stress tests and to compare the data obtained with the results of the examination of the control group.
MATERIALS AND METHODS: The study included patients with takotsubo syndrome (n = 48), including 43 (89.6%) women; the average age of the patients was 63.3 13.5 years, and healthy volunteers of the same sex and age (control group, n = 40). All the subjects with takotsubo syndrome in the acute (first 714 days from the onset of the disease) and in the long-term periods of the disease (after 1 year and 2 years) and the ones in the control group underwent cardiorhythmography at rest to assess the heart rate variability after mental stress tests and against the background of vegetative tests.
RESULTS: According to the cardiorhythmography at rest, in 47 (97.9%) patients with takotsubo syndrome, the influence of sympathetic nervous system on the heart rate prevailed, which persisted in the long-term period of the disease. The vegetative tests revealed a paradoxical reaction of the sympathetic nervous system and reduced activity of the parasympathetic nervous system in the acute and late periods of takotsubo syndrome, compared with the control group. In the acute and long-term periods in the patients with takotsubo syndrome after mental stress tests, in comparison with control group, there was no increase in parasympathetic nervous system activity.
CONCLUSIONS: According to the study findings, the patients with takotsubo syndrome revealed autonomic dysfunction in the form of an excessive increase in the activity of the sympathetic nervous system both before the onset of the disease, and in the acute and long-term periods as well as a decrease in vagal tone, which was reflected in the suppressed response of the parasympathetic nervous system to the deep-breath test and mental stress tests.

The combination of O2, CO2, and low concentrations of CO in CO-MAP has repeatedly been shown to increase the shelf-life of red meat products. Concentrations of CO2 of 30% has been shown to slow microbial growth while O2 preserves the natural color of red meat. The addition of low concentrations of CO (0.4%) preserves the color stability of the meat while allowing for lower levels of O2 which reduces the oxidative spoilage of the product. Shelf-life extension of 5 to 10 days above traditional MAP has been seen with CO-MAP technologies. The addition of active/smart films such as antimicrobial films and/or the combination of irradiation further extends the shelf-life of red meat. Undetectable levels of E. coli at storage temperatures as high as 10oC at 28 days have been shown with CO-MAP and irradiation.

Authors: Bychkov Pavel
Published: May 2023

Due to the local cult of the miraculous statue of Virgin Mary that emerged in the 14th century religious fraternities began to play a leading role in the daily life of citizens, attracting to the town famous architects, artisans, composers and artists (among them was Hieronymus Bosch). But besides religious communities, professional corporations were also important actors in the urban commune, uniting artisans of various specialties around one patron. The most significant guilds in Hertogenbosch were the communities of clothiers and blacksmiths, which formed the main articles of the town’s exports. Areas, in which those craftsmen settled, formed a specific topography of the inner-city space. The core of it was the market square with the houses of the richest members of commercial and administrative elite. Apart from the two main sites — the market and St. John’s cathedral, erected much later — in the urban landscape were present important monasteries and cloisters; belonging to fraternities of beguines and Brotherhood of Common Life. The economic, socio-political, religious and cultural activities of these numerous urban communities formed the environment in which the everyday activities of the inhabitants of Hertogenbosch took place during the 14—15th centuries.
“Closed Door”: the Chinese Crisis and Models of Colonial Order as Assessed by the US Expert Journalistic Community in the Early 1930s
Authors: Buranok Sergey
Published: May 2023

The paper is devoted to the problem of approaches and assessments of the Chinese crisis of 1930s in the US press. No research in China’s image and image of “open door” during the china-japanese war would be complete without studying the press of the participating parties. In order to give a detailed analysis of the international relationships in terms of the global transformations from the American point of view, the authors analyze relevant newspaper articles published after the 1930s. The paper is based on materials of democratic and republican editions of the USA press. The materials of the American press of 1930s, dedicated to the search for the most efficient optimal strategy of building relations with China and Japan, show that among other things there is a steady interest of American mass media towards negative and positive experience of Asian policy. All the complexity of the crisis perception was reflected in the press, which tried to form an understanding of the new process in which America was involved. In the course of a difficult search of an optimal way and a view on the crisis, several polar points of view were formulated in the American press. The image of China was an important factor in the US information policy. Thus, the study of the attitude of the major American press and the positions of the most prominent journalists is of interest to the analysis of how the USA after the Chinese crisis gradually realized the place of the country in the new system of international relations. In addition, the press shows how the United States planned to develop interaction with the warring states in the Pacific Ocean.

A dominância em termos de abundância da entomofauna nos ecossistemas se dá especialmente pelas variadas funções ecológicas que possuem. Os insetos são fundamentais para a manutenção dos agroecossistemas uma vez que interferem na produção primária do cultivo. Conservar a abundância da entomofauna benéfica nos agroecossistemas é crucial para a estabilidade ambiental do habitat. Esse estudo teve como objetivo analisar a composição e a estrutura da comunidade de insetos presentes em um policultivo de olerícolas orgânicos na região Sul de Santa Catarina. A pesquisa foi desenvolvida na Chácara Koscrevic, localizada no município de Laguna, Santa Catarina, Brasil. Foram realizadas seis amostragens no verão de 2019/2020 e na primavera de 2020 com auxílio de armadilhas de queda tipo pitfall iscadas (sardinha e mel) e distribuídas aleatoriamente por cultivo de acordo com a rotação de culturas. Foi registrado um total de 4.303 indivíduos, distribuídos em oito ordens, sendo Coleoptera e Hymenoptera as mais abundantes. Em termos de dominância, no verão prevaleceu indivíduos de Coleoptera, totalizando 1.106 indivíduos e na primavera Hymenoptera, com 628 indivíduos. Os dados indicam que a estrutura da entomofauna pode ser afetada pela estação climática. A fauna no verão é mais diversa, quando comparada com a primavera, seguindo o padrão característico dos insetos. Os atributos edáficos têm significância em relação a fauna e interferem na sua estrutura. Observou-se a presença de insetos benéficos, como espécimes de Dermaptera, Staphylinidae e Megacephala (Tetracha) fulgida, colaborando para o controle biológico de pragas e a polinização das plantas cultivadas, demonstrando sustentabilidade nos cultivos orgânicos.

Inclusion and Equity: Mapping the Legislative Landscape of Non-State Education in the MENA Region
Authors: Farhat Janaan , Mansur Natasha
Published: May 2023

The nonstate education sector has experienced rapid growth globally and in the Middle East and North Africa (MENA) in the last three decades (Al Qasimi Foundation, 2021). This rapid growth has had a major effect on issues of sound education provision, financing, and equity. While several studies have explored this regional trend of expansion in private education, in particular (Ridge et al., 2016b; Abdelkhalek & Langsten, 2019), few have attempted to discuss the extent to which nonstate education legislation addresses issues of equity and inclusion.

As such, this report examines legislation and regulations for the nonstate education sector across MENA countries, focusing in particular on equity and inclusion. It attempts to do so by assessing whether laws and policies delineate limitations on fee-setting and profit-making, while further examining whether nonstate education legislation accounts for the inclusion of persons with disabilities (PWDs) and those from disadvantaged backgrounds. It begins with a background discussion of the growth and categorization of nonstate education in the MENA region. Next, the methodology and typologies of nonstate education are outlined, before presenting the discussion section, challenges, and recommendations for policymakers.

Influence of gaseous mixture parameters on the maximum burning temperature and combustion rate of carbon particle
Authors: Kalinchak V. V. , Chernenko A. S. , Korchagina M. N.
Published: May 2023

The method is developed to determine the maximum temperature of burning carbon particle and corresponding value of particle diameter by using the maximum temperature as a parameter depending on surrounding gas temperature and oxygen content. This method allows finding a limiting value of oxygen content below which ignition of a carbon particle is not possible in cold oxygen-nitrogen mixture. It is shown that the particle temperature attains a maximum value in the transitional regime of chemical reactions. The rise of the burning temperature with the particle size decrease is caused by relative decrease of radiation heat loss.

Authors: Aslanov S. A. , Kosoy M. B.
Published: May 2023

On the basis of weight and energy balance equations self-contained model of the continuous deformation process and the subsequent disintegration of a thin fluid stream on drops under the influence of surface tension forces is constructed. The constructed model includes two stages of the continuous deformation of the site of a cylindrical stream: deformation of poorly indignant surface of sine type to an elliptic drop with terminating values of curvature; deformation of an elliptic drop in coextensive spherical. Expressions of works of surface tension forces at each stage of deformation are received. The made calculus of the equation of balance of weight and energy allowed to uniquely determinate the relative size of effective diameter of the formed drops and distances between them. The received results well will be coordinated with the known experimental observations of Savart and Plateau.

A Universal Soil Loss Equation (USLE) é um dos principais modelos para avaliar a erosão hídrica, no qual a perda de solo é o produto de vários fatores, entre eles o de erosividade da chuva (R). A importância de estudos sobre a erosividade da chuva em meios urbanos vem ganhando cada vez mais destaque, principalmente porque além das perdas de solo, as chuvas também causam grandes danos em infraestruturas e obras de engenharia hidráulica. Assim, foi determinada a influência das anomalias climáticas ENOS (El Niño Oscilação Sul) e Dipolo do Atlântico sobre o fator R mensal da cidade de Belém entre os anos de 1986 e 2015. O Índice de Oscilação do Niño (ION) foi usado para verificação da ocorrência do Dipolo do Atlântico através dos índices TNA (Tropical Northern Atlantic) e TSA (Tropical Southern Atlantic). Os resultados demonstraram que em Belém, Estado do Pará, o potencial erosivo das chuvas é afetado pelo fenômeno ENOS, de modo que um maior número de meses teve menor potencial erosivo durante ocorrência de El Niño (EN). Observou-se também que, em períodos de La Niña (LN) combinados com períodos de Dipolo Negativo, a erosividade é maior.

Este trabalho buscou determinar o valor do índice erosividade da chuva para Óbidos/PA, além de avaliar o seu período de retorno e probabilidade de ocorrência, analisar a distribuição anual deste índice e correlacioná-lo com a precipitação local. Para isto, utilizaram-se dados de precipitação, de 1986 a 2015, de uma estação meteorológica do INMET localizada no município. A partir destes, calculou-se o índice de erosividade para todos os anos de análise, gerando um índice final. Calculou-se a frequência dos valores dos índices e os períodos de retorno correspondentes, que foram plotados em curvas de probabilidade de ocorrência para análise. Realizaram-se análises de regressão para analisar a relação entre a erosividade e a precipitação. No período de análise, a erosividade da chuva para Óbidos foi 13.361 MJ mm ha-1 h-1 ano-1, com probabilidade de 52% de ser equiparado ou excedido pelo menos uma vez a cada 2 anos. Este valor do índice de erosividade classificou a região em área de Muito Alta Erosividade. Nos meses de fevereiro, março e abril são esperados os maiores riscos de erosão, com 60,88% do valor total da erosividade anual. Na análise de regressão, o modelo matemático que apresentou melhor correlação foi o linear (r² = 0,9991).

THE SIGNIFICANCE OF DYNAMIC FORCES ACTING ON A GONDOLA CAR WHEN UNLOADING BY A ROTARY CAR DUMPER
Authors: Viznyak Ruslan
Published: May 2023

The article considers the factors influencing the strength of gondola cars during unloading on rotary car dumpers, before which a preliminary careful analysis of their characteristic damage and malfunctions was carried out. The calculated schemes of the system design are constructed and the analytical determination of the inertial components of the dynamic overturning process is performed. Initial recommendations for the design of the body structure, which is exposed to high dynamic loads during the mandatory unloading of the freight vehicle. The issue of fleet conservation is important for owners and operators of rolling stock, based on the balance of working and non-working fleet. The main cause of damage to the load-bearing structure of the gondola is non-compliance with the content of regulatory documents when performing loading and unloading operations. Unloading of gondola cars in the method of overturning was introduced at industrial enterprises in the last century during the intensive industrialization of the German experience and supply of equipment and is now successfully carried out using special technical devices - stationary rotor tippers. According to the results: acceleration of the PV body occurs at an angle of rotation of about 60°; the maximum values of accelerations are observed at an angle of rotation of 125°. This is done at the final stage of the flow of the load, because the final component of the full angle of rotation no longer affects the dynamics, because the load in the body is not a large part. The results of theoretical research at the design stage of the PV allow to take into account possible dynamic factors due to the overturning of the PV body, and prevent probable damage, assess the margin of safety and reliability of the body structure, which will ultimately reduce maintenance costs and increase life cycle load.

La argumentación en la Respuesta a Sor Filotea de la Cruz
Authors: Merino Silicani Rosanna María
Published: May 2023

Sor Juana Inés De La Cruz, mujer excepcional del siglo XVII, deslumbra por sus dotes de poetisa y su talento intelectual; pero destaca más, según la opinión de muchos y la mía propia, por lo segundo. No en vano esta mujer docta recoge la admiración de sus contemporáneos y la nuestra por la búsqueda del concepto agudo, la precisión en el razonamiento y la coherencia de sus argumentaciones. El texto que nos ocupa es, precisamente, una brillante muestra del manejo de estos recursos.
Pintoras que cuentan : Leonora Carrington, Remedios Varo, Frida Kahlo
Authors: Minardi Giovanna
Published: May 2023

En enero de 1940 tiene lugar en México, en la galería de Arte Mexicano de Inés Amor, la exposición surrealista, la tercera a nivel internacional, que, según Luis Mario Schneider, «es el gran acontecimiento cultural y social de México». Los organizadores de este evento social y snob fueron el pintor austriaco Wolfgang Paalen, que había llegado a México en 1939, y el poeta César Moro. Se prepararon dos salas: una para los artistas internacionales y otra para los artistas mexicanos. Frida Kahlo formaba parte de los primeros, así como Leonora Carrington y Remedios Varo.
El encantador divino (una loa y un dramaturgo novohispano del siglo XVIII)
Authors: Buxó José Pascual
Published: May 2023

La página inicial del manuscrito madrileño -llevado a la península por el propio autor o quizá remitido por alguno de sus correligionarios con el propósito de que allí se imprimiera o divulgara- contiene los mismos datos biográficos que se anotan en las portadas de las publicaciones a las que nos hemos referido, sin embargo, nos descubre a un Fray Lorenzo del Santísimo Sacramento cuyas aficiones literarias no se limitan a la oratoria sagrada, sino que se extienden al cultivo de la poesía lírica y dramática, actividad de la que hasta ahora no se tenía ninguna noticia.3 Por más que en el mencionado volumen se hayan copiado algunas composiciones ajenas -que serían muy del gusto de Fray Lorenzo-,4 la inmensa mayoría de ellas se le puede atribuir sin dificultad.
La intertextualidad olvidada : Ercilla y García Lorca en la biblioteca de Borges
Authors: Ramírez Molas Pedro
Published: May 2023

El desocupado lector, que conoce la biblioteca bautizada por Borges con el nombre de Biblioteca de Babel, disculpará que no lo invite a entrar en ella. No es descortesía de mi parte, sino mera imposibilidad, porque no tiene puerta de entrada ni de salida. En realidad, ya todos estamos dentro de ella, porque todos somos no solo lectores, sino también bibliotecarios de esta inmensa biblioteca que algunos llaman el universo. La imposibilidad de entrar y salir (a no ser saltando al vacío de un pozo de ventilación) implica sus consecuencias prácticas: la biblioteca tiene 24 horas diarias de atención al público, carece de servicio de préstamos a domicilio y no necesita un sistema de multas para devoluciones retrasadas. Todos los libros están en libre acceso. La enorme ventaja de la biblioteca reside en su inmensa cabida, que hace innecesaria cualquier ampliación, y en su inagotable riqueza, puesto que contiene todos los libros pretéritos, presentes y futuros, en todas las lenguas y en todas las ediciones posibles, lo cual permite renunciar también a un presupuesto de adquisiciones. Es más, la destrucción o la pérdida de cualquier libro no significa ninguna reducción del caudal bibliográfico, puesto que todas las obras están presentes en un sinnúmero de ejemplares que apenas difieren entre sí por una coma o una insignificante errata de imprenta. Desde luego, la biblioteca tiene también un grave inconveniente, y es que hasta ahora nadie sabe dónde está el catálogo general. De hecho, pues, en esta biblioteca no se pierde nada o casi nada, pero tampoco se encuentra nada o casi nada.
Epístola de Amarilis a Belardo : análisis de la construcción del sujeto literario
Authors: Sumalavia Ricardo
Published: May 2023

Mucho se ha discutido y dicho sobre la identidad de Amarilis. Si fue María de Figueroa, María de Alvarado, María Tello de Lara o María de Rojas y Garay, como sostuvo últimamente el estudioso Guillermo Lohmann, poco o nada mueve a esta reflexión. Nuestra lectura se guía por la siguiente proposición: el sujeto Amarilis es tal, y no otro, en tanto se construye en el propio texto. Para una aproximación más adecuada a esta reflexión es pertinente aplicar la categoría de análisis sujeto colonial, refiriéndose tanto al sujeto colonizador como al colonizado.1 Esta aplicación nos será útil mientras nos ciñamos a dos sujetos en particular: Belardo y Amarilis. El sujeto colonial, a decir de Rolena Adorno, «no se define según quien es sino cómo ve; se trata de la visión que presenta». 2 Justamente aquí trataré de analizar cómo un sujeto en el texto representa al otro, cómo se ven u oyen, y cuáles fueron sus mercantilismos de representación, ya que, como queremos sostener, ellos son sujetos en tanto se representan al interior de sus propios textos en un perpetuo diálogo.
Cuerpo y religión en las narrativas sobre Eva Perón
Authors: Susti Alejandro
Published: May 2023

Un aspecto poco estudiado en las narrativas basadas en la vida de Eva Perón - sean estas biografías, novelas, testimonios- consiste en el contenido religioso de las representaciones del personaje recogidas en ellas; me refiero en particular a determinadas prácticas comúnmente asociadas con su cuerpo, así como el sentido que estas prácticas asumen en relación con las circunstancias políticas y sociales en las cuales le toca desenvolverse. Los numerosos relatos que muestran de qué manera Eva Perón se identifica con los que sufren o padecen -cómo intenta aliviar o reducir este padecimiento a través de donaciones, gestos, sacrificios, siempre respaldados en su palabra- , la respuesta de aquellos a esta entrega y la forma en que conciben el rol del personaje en el contexto político del período, las descripciones de su corporalidad - la transparencia y color de su piel- , prácticas asociadas con esta corporalidad - la carencia de una adecuada alimentación y proclividad a la enfermedad- son todos temas recurrentes en biografías, testimonios y novelas bajo los cuales se filtra un fuerte componente religioso cuya importancia ha sido poco tratada por la crítica.
Los cuentos de la Baronesa
Authors: Vargas Llosa Mario
Published: May 2023

La Baronesa Karen Buxen DE Rungstedlund, que fue una gran escritora y firmó sus libros con el seudónimo de Isak Dinesen, debió de ser una mujer extraordinaria. Hay una foto de ella, en Nueva York, junto a Marilyn Monroe, cuando era ya solo un pedacito de persona consumida por la sífilis, y no es la bella actriz sino los grandes ojos irónicos y turbulentos y la cara esquelética de la escritora los que se roban la foto.
Evolución del estilo y la estructura en José María Arguedas
Authors: Zavaleta Carlos Eduardo
Published: May 2023

Propongo a los lectores efectuar un viaje de 1934 en adelante a fin de analizar a grandes rasgos la evolución del estilo y de la estructura en las narraciones de Arguedas, cuya carrera se inicia de modo muy humilde en relatos que difícilmente podemos llamar cuentos, como son los recogidos por José Luis Rouillón. Sin embargo, de ese Arguedas dudoso y primerizo va a surgir gradualmente despierto un valioso escritor, a quien conoció y saludó mi generación de narradores de los años cincuenta, a la cual él se dirigía en broma como «ustedes los técnicos» (por nuestra dedicación a Joyce, a Faulkner, a Hemingway, a Borges, etc.), para acabar él mismo, en su madurez, experimentando con el tema, el estilo, el orden temporal, la atmósfera, los personajes y el remate, y hallando, por lo demás, un camino propio, no solo literario sino también cultural, válido para todo el país. En verdad, él fue valiente al desafiar la propia literatura indigenista y neoindigenista, y desafiar, asimismo, la hegemonía castellana para crear, no diré «injertos» ni «híbridos», porque suena mal, sino puentes efectivos de comunicación entre el castellano y el quechua, por canales más profundos que los de Ciro Alegría o Enrique López Albújar. Al César lo que es del César.
La historia de los Incas narrada desde el norte : releyendo a Prescott
Authors: Adorno Rolena
Published: May 2023

En las crónicas y los ándes (1995a), Franklin Pease G. Y. se reveló una vez más como un lector asiduo de William Hickling Prescott (1796-1859), anotando meticulosamente el uso de las fuentes cronísticas en su Historia de la conquista del Perú (1847; ver Fig. 1). De esta manera destacaba la importancia de Prescott para la historiografía peruana. Guillermo Lohmann Villena (1959b: 5) también ha señalado la trascendental influencia de las obras del historiador norteamericano, "a causa de que en ellas se inició el tratamiento del tema de la conquista con todo el aparato heurístico y crítico propio" del siglo XIX. Ese aparato heurístico y crítico ha tenido muy larga vida, según el historiador norteamericano Richard Kagan (1998: 325), quien ha estudiado recientemente los supuestos básicos de Prescott sobre España y los Estados Unidos, y la trascendencia de la óptica prescottiana para la posterior historiografía estadounidense sobre España. Para Prescott, la España del siglo XVI se caracterizaba por la monarquía absolutista, el fanatismo religioso y la indolencia del pueblo, y los Estados Unidos del siglo XIX por el republicanismo federal, el protestantismo racional y el carácter emprendedor de los ciudadanos (Kagan 1998: 329).
Del camino de la sierra a la conquista del Perú
Authors: Castelli Amalia
Published: May 2023

Con la seguridad de que parte de la información de Hernando Pizarro, y de otros testimonios de los protagonistas de los encuentros entre europeos y americanos, fueron perennizados en la carta a los oidores de Santo Domingo (1533), ésta debe haber sido la fuente usada por Gonzalo Fernández de Oviedo para presentar su "verdadera relación" de la conquista del Perú. Oviedo, vecino principal y alcalde de Santo Domingo, se nutrió de las informaciones dadas por Francisco de Xerez, el secretario de Pizarro, y gracias a ella construyó su "verdadera relación". Aunque Ake Wedin ( 1966) se refiere a la crónica de Oviedo como una fuente de segunda mano, no niega la importancia del material que reúne y lo califica de valioso y temprano, adjetivos de gran importancia en el caso del análisis de las crónicas, dado que no son muchas las informaciones de este tipo. U no de los tópicos que con frecuencia vamos a encontrar en la lectura está referido principalmente a la justificación de la acción española en el proceso de la conquista.
