FLUXOS, POÉTICAS E (DES)CONTINUIDADES:
Authors: Alvarenga Pereira Marlyson Junio , Pinto Gonçalves dos Reis Fábio , Davi Mazzei Luiz
Published: May 2021

Os percursos teóricos-metodológicos, suas rupturas, (des)continuidades e poéticas são trazidos, neste texto, ao nosso olhar. Pesquisas científicas, por vezes, preocupadas com os resultados de seus estudos terminam por deixar à sombra o percurso percorrido. Partindo das trajetórias trazidas por “pesquisadores-caminhantes”, buscamos discutir a importância dos aportes teórico-metodológicos nas pesquisas pós-críticas. Valendo-nos de um “mapa” construído nas/pelas pesquisas apresentadas no “I Seminário Integrador: Tecituras em redes de discussões e afetos: interfaces com as questões de gênero e sexualidade”  ocorrido entre  23 e 25 de novembro de 2020,  voltamos nosso olhar para alguns aspectos (territórios) que compuseram esse mapa: o olhar do outro, a dicotomia eu-outro, as questões étnico-raciais, a medicalização dos corpos e da sexualidade, os artefatos culturais, os dispositivos que normatizam e permeiam as relações de saber-poder. De posse desse mapa, buscamos discutir a riqueza, a pluralidade e a beleza dos caminhos percorridos nas pesquisas pós-críticas, especialmente nas questões de gênero, sexualidade e educação.

Authors: Aparecida dos Santos Dolneia , Vargas Juliana , Ribeiro de Vargas Juliana
Published: May 2021

Neste estudo buscamos analisar e problematizar representações de maternidade, a partir de narrativas de jovens mães e gestantes, na faixa etária entre 17 e 23 anos de idade, estudantes do Ensino Médio de uma escola pública da periferia de Canoas (RS). Para tanto, buscamos como aportes teóricos os Estudos Culturais em Educação, os Estudos de Gênero e os Estudos sobre Juventude. Como metodologia, aplicamos um questionário exploratório e, posteriormente, organizamos encontros de Grupo Focal, entre novembro e dezembro de 2018. Tais ferramentas subsidiaram organização das seguintes unidades analíticas: “Sou uma boa mãe - narrativas de afeto e atenção”; “Sou uma mãe, mas continuo sendo jovem, quero curtir a vida”. A partir de tais análises, destacamos a construção de maternidades juvenis plurais, que se distanciam das representações naturalizadas da maternidade e da juventude, as quais necessitam precisam ser mais bem estudadas e problematizadas em nossas instituições de ensino.
Queering Brazilian Horror: Race, Class, and Sexual Orientation in As boas maneiras (2017)
Authors: Oliveira-Monte Emanuelle K. F.
Published: May 2021

In Brazilian cinema, the horror genre is closely associated with the masculine prowess of José Mojica Marins’s character Zé-do-Caixão. Juliana Rojas and Marco Dutra’s film As boas maneiras/Good Manners (2017) transposes horror to lesbian desire. This article examines how As boas maneiras queers Brazilian horror, focusing on the relationship between the two female main characters. Carefully suspended within the tension between the drive to create alternative models of desire, sexuality, and familial arrangements and an oppositional push to return to white heterosexual patriarchal norms, the movie delivers a criticism of the racism, sexism, classism, and homophobia in Brazilian society.
Geochemistry of Amphibolites in Akom II, Nyong Series, North Western Border of the Congo Craton, South Cameroon
Authors: Anehumbu Aye Beyanu , Azinwi Tamfuh Primus , Tata Enerst
Published: May 2021

The garnet amphibolites, from the Akom II area in the Archaean Congo Craton, were examined to determine the geochemical affinity and tectonic environment. The study uses mineral assemblages and whole-rock geochemistry to identify the geochemical affinity and tectonic setting of the amphibolites associated with monzogabbro and pyroxenites. The studied rocks of Akom II are garnet amphibolites. Mineralogically, the rocks contain hornblende + plagioclase + garnet Â± quartz Â± epidote Â± apatite Â± opaque, indicating that they could have been formed from a basic igneous protolith. The geochemical signature indicates that the rocks are tholeiitic in nature. They are similar to the metamorphosed equivalents of ocean island basalts (OIB), with characteristics typical of Volcanic Arc-Basalt (VAB). The geotectonic diagrams confirm the tholeiitic nature of these amphibolites. High field strength elements ratios (Nb/Ta) range from 14-16, which corresponds to Volcanic Arc Basalt (VAB). The primitive mantle normalized patterns of these rocks show negative anomalies in Ta and Ti suggesting a geotectonic signature characteristic of a subduction zone, consequently suggesting the existence of a suture zone in the study area.Â Â Â

Authors: Hilmi Muhammad Anis Al , Sumarudin A , Putra Willy Permana
Published: May 2021

Hampir semua aplikasi web yang memerlukan pengesahan / autentikasi, menggunakan mekanisme verifikasi password untuk masuk ke dalam sistem. Bagi pengguna, password adalah dilema. Password yang aman seringkali sulit untuk diingat, sedangkan password yang mudah diingat biasanya mudah untuk ditebak. Pengguna juga melakukan hal teledor seperti menulis password di sticky note dan semacamnya, juga menggunakan password yang sama untuk akun berbeda sehingga membuat keamanan akun semakin rentan, terutama karena serangan dengan keylogger. Untuk mengatasi hal ini, telah dikembangkan beberapa teknik pengamanan, seperti menambah faktor lain ketika login dengan kode One-Time-Password (OTP) lewat SMS, perangkat token generator seperti yang dipakai perbankan, login dengan hardware USB, akses lewat sensor biometrik fingerprint, bahkan electrocardiogram (ECG). Dengan menilik kelebihan dan kekurangan aneka pendekatan yang telah dikembangkan serta dengan orientasi fokus kepada kemudahanan pengguna, penelitian ini  mengusulkan perangkat dan metode untuk memperkuat keamanan sistem dalam proses login, dan tetap mudah dalam penggunaannya (tanpa secara manual mengingat, memasukkan username dan password), portabel, dan terjangkau. Pada makalah ini autentikasi dengan OTP diajukan dengan metode Vigenere chiper yang dimodifikasi dengan nilai salt yang selalu berubah dan pengacakan data menggunakan algoritma butterfly. Ditambah pengamanan menggunakan perangkat keras berbasis microcontroller, sensor fingerprint, dan modul Real-Time-Clock (RTC) untuk validasi kepemilikan dan sinkronisasi waktu dalam mencegah keylogger attack. Hasil pengujian memperlihatkan perangkat dapat menghasilkan OTP dengan waktu rata-rata 0,956 sekon, dan memudahkan pengguna untuk login ke aplikasi web tanpa perlu mengingat password.
DEMILITARIZED ZONE AND PORT KNOCKING METHODS FOR COMPUTER NETWORK SECURITY
Authors: Saputro Andik , Saputro Nanang , Wijayanto Hendro
Published: May 2021

Currently, the way of network communication has changed a lot. All aspects become very dependent on online services. Employees can work from home, and students of all ages take online classes. The more the public depends on staying connected to the network, the greater potential network attacks to occur. In a computer network, if it is not protected, it will data or file loss, damage to the server system, not being optimal in serving users or even losing valuable institutional assets. The attacks most often used in networks are Port Scanning and DDoS (Distributed Denial Of Service). In this study, the DeMilitarized Zone and Port Knocking methods are combined to secure computer networks. DeMilitarized Zone technique implementation is used to access local servers, so that they can be accessed from outside with Port Knocking technique. To open the access port that is filtered in the router configuration on the server network security system. DeMilitarized Zone and Port Knocking can be implemented on local and long distance networks where if an attacker wants to exploit or attack the main server, the first to be attacked is the firewall server (router). Port Knocking can also be implemented on local and long distance networks with a combined ping request time limit which makes it safer, so that if an attacker wants to access the router, and doesn't know the rules from the remote, what happens is a rejection of port access.

Lo estético como acceso a la realidad en el pensamiento español contemporáneo
Authors: Esteve-Martín Alfredo
Published: May 2021

El pensamiento estético ha sido una constante en la tradición filosófica española contemporánea, y seguramente no ha sido por casualidad. Podemos preguntarnos por qué. Como es sabido, nuestro pensamiento durante el siglo XX ha tenido como uno de sus principales focos de atención «lo vital» o, mejor dicho, la integración de razón y vida: desde el gran paso que supuso el raciovitalismo orteguiano, la preocupación por este tema ha sido una constante entre nuestros autores. Con su pensamiento Ortega se une a una tradición de autores como Schopenhauer, Nietzsche o Bergson, en la que se pone de manifiesto cómo es preciso pensar en diversos modos de ejercer la razón al meramente conceptual o teorético. Esta nueva dimensión se encuentra vinculada al ámbito de lo estético. Así, lo estético deja de ser únicamente una reflexión sobre el arte y la belleza, para erigirse en un modo diverso de acceso a lo real, tal y como se puede apreciar en el mismo Ortega, en d’Ors, Zambrano... y Zubiri, quien con su inteligencia sentiente lleva a su máxima expresión —a mi modo de ver— el acceso estético a la realidad, tal y como explica en sus breves «Reflexiones filosóficas sobre lo estético».
Alteridad, poética y filosofía en la obra de Antonio Machado
Authors: Rodríguez-García María
Published: May 2021

La obra de Antonio Machado muestra una conocida amplitud temática que se manifiesta, además de en su poética, en sus aportaciones a la filosofía. El presente artículo pretende acercarse a su figura desde la conjunción entre la poética y la filosofía en base a un concepto fundamental en su obra: la alteridad. Como consecuencia de la quiebra de la razón moderna, el solipsismo de corte cartesiano quedó en suspenso. Es en este momento en el que tanto en Europa como en la España de finales del siglo XIX surge una tendencia hacia la alteridad o reconocimiento del otro, tal y como veremos en la obra de Machado y en personajes esenciales de su producción como Juan de Mairena así como, también, en otros autores de la generación del 98.
«Poética de la conversión»: la música como gnosis sensorial y el «giro musical» de la filosofía según Eugenio Trías
Authors: Martínez-Pulet José-Manuel
Published: May 2021

En este artículo se analizan en general los diferentes niveles de la comprensión que de la música (como fenómeno artístico) tiene Eugenio Trías, con objeto de discutir más detalladamente los argumentos con los cuales, el filósofo español fundamenta su teoría de la música como gnosis sensorial o poética de la conversión. Para dar cuenta de la misma, Trías acuña el concepto de «imaginación sonora», como forma más excelsa de esa facultad que es la «imaginación creadora», de la cual se recoge, por otra parte, su arqueología filosófica, y de la que se trata de enfatizar tanto su dimensión simbólica de sutura (pues en la pieza musical acontece el cerco fronterizo), como de su dimensión cognitiva (gracias a la cual algo capta el fronterizo de forma indirecta del cerco hermético). Esa concepción de la música como gnosis sensorial le servirá como fundamento para exigir un giro musical de la filosofía, que pueda superar el «giro lingüístico».
La vida como proyecto y sentido
Authors: Turró-Ortega Guillem , Seguró-Mendlewicz Miquel
Published: May 2021

El propósito de este artículo es aproximarnos al tratamiento que la cuestión del sentido antropológico ha recibido por parte de dos egregios filósofos españoles. El primer gran bloque estará dedicado a explorar —siguiendo a José Ortega y Gasset— cómo la vida auténtica es genuinamente proyectiva, una empresa mediante la cual se despliega el sentido personal. De este modo podremos ahondar en nociones tan relevantes como la vocación, el destino o el fondo insobornable. En la segunda y última parte, José Gómez Caffarena nos ayudará a cuestionar si la experiencia de sentido es indisociable de la gran pregunta por el Sentido, entendido como el horizonte meta-físico de la vida humana.
Miguel de Unamuno: intersecciones entre metafísica y política
Authors: Iglesias-Granda José-Manuel
Published: May 2021

Este estudio trata de poner de manifiesto que una adecuada comprensión del pensamiento y actuación políticos de Miguel de Unamuno requiere de un conocimiento profundo de la metafísica del autor. La evolución de su vida filosófica, íntimamente relacionada con su devenir existencial, marcó no solo su ideología sino también su forma de entender y hacer la historia y la sociedad. En este sentido se han detectado cuatro ejes de intersección entre política y metafísica. Aunque él mismo consideró que su principal compromiso político radicaba en sus escritos, su participación en la vida nacional fue decisiva. La maduración espiritual le llevó a abandonar los planteamientos utópicos del socialismo y a defender posiciones donde primase la dimensión espiritual del hombre. Gracias a ellas, don Miguel identificó con claridad el peligro tanto de los planteamientos fascistas como comunistas; plantando cara activamente a las manifestaciones de ambos en España. Pues, para él, la misión del país radicaba en la fundamental tarea de vivir y defender la loca filosofía del Sentimiento trágico de la vida.
Imigração e refúgio nos debates e políticas educativas globais: Uma aproximação aos discursos sobre as mobilidades e seus sujeitos
Authors: Magalhães Giovanna Modé , Schilling Flavia
Published: May 2021

Os sistemas educativos, a partir da constatação da presença de imigrantes e refugiados nas escolas, sobretudo nas redes públicas de ensino, emergem como um campo de pesquisa, política e ação para entender os diferentes discursos a propósito das mobilidades contemporâneas. Neste trabalho, nossa preocupação residiu em perceber o quanto o debate e as políticas educativas globais – ainda que incipientes sobre a temática – interagiam, reforçavam ou contradiziam as distintas práticas, representações e dizeres que tomam as mobilidades e seus sujeitos por objeto de regulação e conhecimento. Buscamos observar os discursos que mobilizam, para fundamentalmente entender como se articulam ao paradigma da migração como um problema a combater-se – e não como um dado constitutivo do mundo. Como estratégia metodológica, optamos pela análise de um conjunto recente de documentos orientadores de políticas educativas de alcance global que tratassem de imigração e refúgio, de autoria de organismos internacionais das Nações Unidas. Neste conjunto, destacamos dois aspectos centrais para reflexão: de maneira mais ampla o tratamento dado aos sujeitos individuais e coletivos das mobilidades, e um segundo eixo focado especificamente na maneira como se constrói e se reforça a “figura da vítima”, bem como suas implicações, tensões e ambiguidades.
Green Wrocław: Urban narratives of three post-war generations of Wrocław’s inhabitants
Authors: Biskupska Kamilla
Published: May 2021

This study is an invitation to reflect on issues that fall within the area of collective memory, an area that awaits further in-depth analysis. More specifically, this article is a proposal of a broader study on cultural landscape and places of memory than that which is dominant in the sociological literature. In particular, I examine the relationship between the inhabitants of the Polish “Western Lands” and the material German heritage of the cities in which they happen to live. I mainly focus on the relation between socially constructed memory and greenery—a “negligible” part of the space of human life. As I demonstrate in the article, the “green” narrations about Wrocław created after World War II are lasting and are still present in the stories of city’s inhabitants today.
Urban landscape as biographical experience: Pre-war Lublin in the oral testimonies of its inhabitants
Authors: Kubiszyn Marta , Weismann Stephanie
Published: May 2021

For several hundred years, Lublin has developed as a multiethnic city. As a result of World War II and the destruction of the local Jewish community, its urban structure and its cultural landscape were significantly altered. The image of pre-war Lublin emerging from archival documents, pictures, newspaper articles, and individual memories is multilayered. Studies of the oral testimonies of local inhabitants reveal the deeply sensory and cultural components of spatial experiences characteristic of the cultural landscape of pre-war Lublin. This aspect will be presented as a reference point to conduct analyses concerning cultural and social aspects of the perception of Lublin’s urban landscape.
Extracting limestone: How to interpret the city through ammonites and belemnites
Authors: Sadowska Monika
Published: May 2021

The paper analyzes the presence of the remains of ammonites and belemnites in the stones used to build the elevations of houses in modern Polish cities. The process of aestheticizing buildings is the reason for fossilized cephalopods being moved from the natural environment into urban space. I consider whether the use of such materials leads merely to making the buildings look more attractive or if this process provides an opportunity to interpret these buildings in an alternative way, which goes beyond aesthetic categories and is related to the fact that the fossils have been moved from the natural world into the cultural sphere. The limestone elements of architecture also allow one to look at the city as a unique museum of cultural and natural history.

Published: May 2021

Die kontinuierliche Weiterentwicklung induktiver Näherungsschalter erweitert zunehmend deren Anwendungsbereiche. Gleichzeitig erlauben der stetige Fortschritt der Mikroelektronik und die höhere Integration von Rechen- und Speicherelementen in Mikrokontrollern komplexere Datenverarbeitung in kompakten Sensorsystemen. In diesem Beitrag wird ein neues Messverfahren vorgeschlagen, das zusätzlich zur eigentlichen Funktion der Präsenzerkennung bzw. Abstandsmessung die Unterscheidung verschiedener Target-Materialien ermöglicht. Das Prinzip dieses Verfahrens wird zunächst vorgestellt und mithilfe eines automatisierten Messaufbaus demonstriert. Im Anschluss werden der Einfluss des Materials, der Einbauumgebung und unterschiedlicher Targets dargestellt und diskutiert. Hierfür werden verschieden geformte Targets und verschiedene Targetgrößen der bereits vorgestellten Materialien eingesetzt. Es werden Potentiale dieses Verfahrens in Bezug auf die Unterscheidbarkeit der Targetmaterialien, der Einbauumgebung und Targetform diskutiert und die weitere Übertragbarkeit des Verfahrens bewertet. Abschließend wird die industrielle Verwertbarkeit beurteilt.

Published: May 2021

Zur präzisen Prüfung von Widerstandsthermometern- und Temperatursensoren in Kalibrier- und Eichlaboratorien wurde ein automatisierter Temperaturmessplatz entwickelt, aufgebaut und messtechnisch untersucht. Der Messplatz besteht aus einer Präzisions-Zweikanal-Stromquelle, einer Multiplexereinheit, Referenzwiderständen sowie einem Präzisions-Spannungsmessgerät. Die zu prüfenden Widerstände und Temperaturfühler werden mit konstanten Gleichströmen (direct current, DC) in zwei Messrichtungen gespeist und die resultierenden Spannungsabfälle gemessen. Der Aufbau ermöglicht die Messung von Widerständen und Temperatursensoren mit geringen Messabweichungen und Messunsicherheiten. Der Messplatz wird durch Referenzmessungen mit Normalwiderständen und eine umfassende Messunsicherheitsbetrachtung charakterisiert.
ficción en búsqueda del realismo. Un análisis de “Los Favoritos de Midas (2020)”: periodismo, política y contrapoder
Authors: Gil-Torres Alicia
Published: May 2021

El entretenimiento ocupa un lugar predominante en la sociedad actual, ya sea por el desplazamiento de la información y la producción de un híbrido denominado infoentretenimiento o como bienes y servicios multimedia para consumo inmediato o en diferido. En este último grupo, Netflix -que llegó a nuestro país en 2015- se erige como la plataforma de streamingcon más suscriptores en España (Expansión, 2020). Además de servir para la compra de productos audiovisuales es productora de series, documentales y películas originales creadas y rodadas en diferentes países. En noviembre de 2020 lanzó una de sus últimas producciones: la miniserie limitada “Los favoritos de Midas”, que centra el caso de estudio. A través de una metodología cualitativa fundamentada en estudios anteriores de otros autores y aportaciones propias, se genera una ficha de análisis para examinar el conjunto de esta propuesta argumental (no tan) ficticia a través de cuatro grandes dimensiones: personajes, escenarios, contextos y acciones. De esta manera se pretende descubrir si el proceso de construcción figurado de las situaciones mostradas y de los personajes se corresponden con patrones de la realidad. Además, el periodismo, elemento recurrente en la ficción española, es en numerosas ocasiones el hilo conductor de algunas de las tramas ya sea recurriendo a periodistas, a códigos éticos o a imperios mediáticos. Los resultados reflejan que acudir a elementos reales para dar verosimilitud a la ficción es un recurso patente y que el periodista sigue constatándose como un protagonista de peso ejerciendo como contrapeso al poder en las historias que involucran asuntos políticos.
Interdependencias entre la heurística y la estrategia de precios: una aplicación para productos de alimentación de gran consumo
Authors: Agustín Cañibano Clara , Cristófol Rodríguez Carmen , Cerdá Suárez Luis Manuel
Published: May 2021

Tradicionalmente, la investigación sobre heurísticas de precios se realiza de forma desvinculada de las estrategias de comunicación en las que se enmarcan los productos y servicios. Este estudio plantea la pregunta de si la heurística de precios funciona de forma similar y es igualmente efectiva para distintas estrategias de comunicación de precios. Concretamente, explora el papel que ejerce la heurística de anclaje de precios en la estrategia value pricing y su impacto en el valor percibido, así como la sensibilidad al precio del producto. Para ello se diseñó un estudio experimental con una muestra de 500 personas, donde el 50% de los participantes fueron expuestos a una condición de anclaje de precio referencial y el 50% restante no fue sometido a esta condición. El estudio se realizó en la categoría de pan de molde con dos productos de pan de la misma marca y línea, con estrategia de precios value pricing y un grupo de control. Los resultados identifican un efecto inverso de la heurística de anclaje en el valor percibido y en la sensibilidad al precio. Este estudio contribuye al desarrollo de la disciplina del neuropricing y la heurística de precios y los resultados tienen implicaciones para los gerentes de comunicación y marketing que desarrollan políticas de precios basados en el valor e interesados en pricing y neuropricing en general.
Estructuralismo de Propp en los periodistas héroes y villanos del cine español
Authors: San José de la Rosa Cristina
Published: May 2021

Los personajes periodistas héroes y villanos ocupan un lugar destacado en el cine español y su estudio aporta una visión de la profesión desde la perspectiva que brinda el rico caleidoscopio del cine. Esta investigación estudia135 películas en siete décadas, desde 1942 hasta 2012, lo que proporciona una inusual panorámica de la evolución del informador y de los medios de comunicación a lo largo del último siglo en nuestro país. La originalidad de la metodología se encuentra en la recuperación de Morfología del cuento(1928) de Vladimir Propp para trasladar el estructuralismo dela literatura ala narrativa audiovisual, una semiosis que configura una exclusiva morfología del periodista. El autor ruso Propp encontró 31 funciones matrices que se repiten en los cuentos del folclore de su país y este trabajo 21 funciones en las películas. El detallado análisis de guiones, secuencias y encuadres se sintetiza en esferas y acciones en las que se mueven los informadores. Héroes y villanos que conforman un novedoso reflejo en la pantalla del periodismo español con un dominio del medio de comunicación tradicional de la prensa escrita, del personaje masculino y del periodista envuelto en una vida de caos emocional y adicciones.

Characteristics of small molecule compounds produced from the co-pyrolysis of cotton stalk and coal
Authors: Tang Chuyang , Yang Lei , Li Xianchun , Song Jinling
Published: May 2021

Pyrolysis experiments of cotton stalk (CS) and Shenmu coal (SM) were conducted in a tubular furnace. The pyrolysis temperature was 600 °C at 5 °C/min and sustained for 15 min. The water-soluble small molecule compounds (WSMC) were derived from the liquid products obtained during pyrolysis with the methods of toluene entrainment and ultrasonic extraction. The compositions of WSMC were further characterized by gas chromatography–mass spectrometry (GC-MS). The components of the syngas were analyzed by gas chromatography (GC). The results showed that the phenol yield was promoted by the interaction of CS and SM during co-pyrolysis. Moreover, the co-pyrolysis interaction blocked the radical reaction pathway that produces amides and accelerated the formation of pyridines. Because the ester yield increased, the esterification was clearly enhanced and the yield of carboxylic acids in WSMC was reduced during co-pyrolysis. In addition, the inhibition of furan generation resulted in an increased yield of C2–C4 hydrocarbons in the co-pyrolysis syngas. The maximal yields of C2–C4 hydrocarbons all occurred at a 20/100 ratio of CS/SM. Lastly, the formation mechanisms of small molecule compounds were proposed.
Caulerpa sertularioides extract as a complexing agent in the synthesis of ZnO and Zn(OH)2 nanoparticles and its effect in the azo dye’s photocatalysis in water
Authors: Garcia-Bedoya Daniel , Ramírez-Rodríguez Luis P. , Quiroz-Castillo Jesús M. , Esquer-Miranda Edgard , Castellanos-Moreno Arnulfo
Published: May 2021

Algae constitute a diverse group that is useful in many biotechnological areas. In this paper, the usefulness of Caulerpa sertularioides methanol extract in the synthesis of ZnO and Zn(OH)2 nanoparticles was explored. This work had two main objectives: (1) to use the extract in the synthesis as an organic harmless complexing agent, and (2) to enhance a photocatalytic effect over AZO dyes in wastewater from fabric industries without adding nanomaterial to the environment due to its toxicity. Caulerpa extract performed the expected complexing action, and nanoparticles were formed in a size range from 45 to 69 nm. X-ray diffraction analysis (XRD), transmission electron microscopy (TEM) and UV-Vis spectroscopy were used to characterize the system. It was demonstrated that the nanoparticles were useful to photocatalyst AZO dyes in the water, while contained in tetraethylorthosilicate composites. These could be used in industrial wastewater and are expected to have no environmental consequences because the composites do not add nanoparticles to the water.

Published: May 2021

The extraction of bayberry tannins has potential to maximize the utilization of a forest waste. This study employed a four-level central composite design through response surface methodology to optimize the extraction of tannin from bayberry barks through ultrasound-assisted extraction (UAE). The effects of solute to solvent ratio (STSR), solvent concentration (SC), extraction time (ET), and sonication temperature (ST) on the total extraction yield of total condensed tannin (TCT yield) and total phenolic content (TPC) were investigated. The extracts were characterized with matrix-assisted laser desorption-time of flight mass spectrometer (MALDI-TOF MS), nuclear magnetic resonance (NMR), and gel permeation chromatography (GPC). The optimized condition was reached when the STSR and ST were set at 1:57.16 g/mL and 71.3%, when the ET and the ST was 39.1 min and 48.75 °C. In these conditions, the TCT yield and TPC reached their maximum values of 17.55% and 365.01 mg GAE/g, respectively. Furthermore, the polyflavonoids of bayberry tannin ranged from dimers to heptamers, which were only composed of proanthocyanidins (PC) containing galloy groups.

The influence of a number of physical characteristics and parameters of metallic fiber materials on their thermal conductivity is studied in this work. Such porous materials are intended, among other things, for their effective use in two-phase heat transfer devices (heat pipes). The use of heat pipes in aircraft and space vehicles provides a number of thermophysical advantages. In particular, heat pipes significantly expand the possibilities of air cooling of heat-loaded technical devices. The thermal conductivity of capillary-porous materials-structures, which are important elements of heat pipes, significantly affects the intensity of two-phase heat transfer inside heat pipes. Frame thermal conductivity is equivalent to the thermal conductivity of materials that are conditionally continuous medium. Studies of the influence of structural characteristics of porous materials, such as porosity and parameters (dimensions) of discrete particles-fibers (fractions of the studied materials), were performed using special experimental equipment created at the I.M. Frantsevich Institute for Problems of Materials Science of the National Academy of Sciences of Ukraine (Kyiv). Porous metal structures (coatings) made of copper, nickel, and steel fibers (MPM) were investigated under conditions similar to those for space heat pipes. The porosity values ​​of the prototypes of materials were in the range of 40 to 93%. The research results showed that the following physical characteristics of capillary structures, such as values ​​of thermal conductivity of metallic materials (fiber fractions), the porosity of capillary-porous metal materials (structures), significantly affect the value of thermal conductivity of porous materials. The dimensions of discrete particles-fibers also affect in a certain way the value of the MBM thermal conductivity but to a lesser degree. The results obtained in this work are summarized in the form of empirical dependencies – formulas, providing engineering calculations of the thermal conductivity values ​​of metal fiber materials. The research results are intended for practical application in aviation and spacecraft apparatus engineering. In particular, the presented results are necessary for the development and creation of effective heat pipes with metal fiber capillary structures.

V.I. Vernadsky’s work "The Beginning and Eternity of Life" (1922), as well as his other scientific works, made a significant contribution to the development of many branches of natural history. It fundamentally changed the scientific worldview of the twentieth century. This work determined the place of man and his scientific thought in the evolution of the biosphere, made it possible to take a fresh look at the surrounding nature as the environment of human existence. It posed many actual problems and outlined ways to solve them in the future. The combination of deep knowledge in various industries with the history of their development determined the formation of V. I. Vernadsky's views on science as a specific natural phenomenon inherent to the genus Homo sapiens. He considered the progress of science as the natural process of the development of human thought, aimed at the cognition of the laws of nature and the laws of its own development. V. I. Vernadsky has analyzed various mechanisms of the origin of life and came to the conclusion that life could be eternal and had no beginning. He emphasizes two geologically most important points: firstly, the planetary, geologically regular nature of life; secondly, the close connection of all geological processes in the biosphere with the activity of living matter. Consequently, the understanding of life as a planetary phenomenon led V. I. Vernadsky to an understanding of the direct dependence of the existence of the biosphere on the conditions caused by geological processes.

OBJECTIVES:

Sharing books with preschoolers is known to improve kindergarten readiness. Both Reach Out and Read (ROR) and Dolly Parton’s Imagination Library (DPIL) have shown positive effects on book sharing at home. We developed a novel combined ROR/DPIL program and examined the effect on kindergarten readiness assessment (KRA) scores.

METHODS:

At urban ROR primary care sites, patients <5 years living in the city school district were enrolled from July 2015 through January 2019 in the ROR/DPIL program when seen for a clinic visit. The literacy subtest of the KRA was examined for participants entering kindergarten in the fall of 2016, 2017, and 2018. The “on-track” rate of participants was compared with nonparticipant groups.

RESULTS:

A total of 797 kindergarten-aged ROR/DPIL participants were matched to Ohio KRA scores for 2016, 2017, and 2018 school years. The percentages of students “on-track” on KRA literacy subtests increased significantly by cohort (2016, 42.9% [95% confidence interval (CI): 34.9%–50.9%] versus 2017, 50.9% [95% CI: 44.9%–56.9%] versus 2018, 58.3% [95% CI: 53.3%–63.3%], P = .004). ROR/DPIL participants were compared with a proportionate stratified random sample of 1580 non-ROR/DPIL peers. On-track in literacy did not significantly differ between groups (2016 [P = .262], 2017 [P = .653], 2018 [P = .656]), nor did they differ after restricting analysis to economically disadvantaged children (2016 [P = .191], 2017 [P = .721], 2018 [P = .191]).

CONCLUSIONS:

With these results, we suggest that a program combining literacy anticipatory guidance at clinic visits and more books in the home can potentially improve kindergarten readiness. Pediatric health care providers can play an important role in promoting kindergarten readiness through literacy promotion.

Congenital diaphragmatic hernia is a defect of diaphragm development which in the majority of cases is associated with penetration of the abdominal organs into the chest. Purpose is to draw attention of pediatricians, general practitioners and family doctors, pediatric surgeons to the issue of timely diagnostics of congenital diaphragmatic hernia since its clinical signs are manifested in patients of a post-neonatal age. Clinical cases. The first review demonstrates a clinical case of a right false congenital diaphragmatic hernia of 6-month child with acute onset of the disease manifested by combination of respiratory disorders and pathological intestinal symptoms, visualization of intestinal loops in the right side of the chest. The second clinical case describes left false congenital diaphragmatic hernia of a 10-month child with subacute onset of the disease, prevailing pathological respiratory symptoms and visualization of the stomach in the left side of the chest. Due to timely diagnostic examination and surgery performed both patients were discharged home in a satisfactory condition. Conclusions. In spite of more favourable course of congenital diaphragmatic hernia in children older than 1 month of age, its development can be of a fulminant character and associated with danger for life. It stipulates the necessity to carry out an appropriate differential-diagnostic complex for all the infants with acute or chronic respiratory disorders and pathological intestinal symptoms including a competent interpretation of the results obtained after plan and contrast radiography of the thoracic and abdominal organs. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: congenital diaphragmatic hernia; Infancy.

Purpose — study of the severity of secondary sexual characteristics in girls with general and genital infantilism in the early reproductive period. Materials and methods. 150 girls with general and genital infantilism were examined. All examined girls underwent clinical, functional, hormonal, biochemical, radiological, genetic and laboratory tests. The average age of girls was 19.56±0.13 (17–22) years. The average weight of the examined was within 55.37±1.56 (32–98) kg, height 1.57±0.13 (1.36–1.71) m. The body-mass index was 22.5±0.48 (15–48). The severity of secondary sexual characteristics was assessed according the J. Tanner scale. Results and conclusions. It was found that adolescents with general infantilism (hypogonadotropic hypogonadism) have a significant delay in the development of secondary sexual characteristics against the background of mild hirsutism (р<0.05). In Patients with genital infantilism (hypergonadotropic hypogonadism), significant axillary and suprapubic hair growth at the background of poor development of the mammary glands was noted. Also the moderate degree of hirsutism was confirmed. With normogonadotropic hypogonadism, the development of secondary sexual characteristics corresponds to similar indicators of practically healthy girls. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. The authors declare no conflicts of interests.

Published: May 2021

The prevalence of gastroesophageal reflux disease (GERD) in children with asthma ranges from 32% to 80%. The intensity of respiratory symptoms, bronchial obstruction are more pronounced in children with asthma combined with GERD than in children with isolated asthma. However, there are limited and conflicting data on the difference between the induced sputum in asthmatic children with or without GERD. Purpose — to examine the status of lung function and features of airway inflammation in children with asthma combined with gastroesophageal reflux disease. Materials and methods. Sixty-seven children ages 6–17 years with moderate asthma and 30 healthy children ages 6–17 years were observed. They were assigned to three groups: group 1 (32 children with isolated asthma), and group 2 (35 children with asthma and GERD) and group 3 (30 healthy children). All children included in the study were identical in age and gender. Clinical assessment, spirometry with test of reversibility of airway obstruction, and cytological analysis of induced sputum samples were performed on all patients. Upper gastrointestinal endoscopy was done in the asthmatic groups. Results. There were 10 (28.57%) children in the 2nd group with first degree obstructive spirometry pattern and none in the 1st group of children. First degree restrictive spirometry pattern was more significant observed in the 1st group of children — 10 (31.25%) than in the 2nd group of children — 2 (5.71%) (OR, CI 95% 7.50 (1.50–37.57)). In the 2nd group of children, induced sputum had a significantly higher number of neutrophils, lymphocytes and macrophages compared to the 3rd group (p<0.05). Also the difference between these parameters were significant compared to the 1st group of children. The number of induced sputum epithelial cells in 2nd group was significantly less than in 1st group of children. Conclusions. GERD negatively affects the parameters of lung function in children with asthma. Airway inflammation in children with asthma combined with GERD appears to be more significant compared to isolated asthma. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of an participating institution. The informed consent of the child's parents was obtained from the studies. No conflict of interest was declared by the authors. Key words: asthma, gastroesophageal reflux disease, children, spirometry, induced sputum.
