Intercooperação e Fusão de Redes Empresariais: Proposição de Framework para Análise sob a Perspectiva da Aprendizagem
Authors: Wegner Douglas , Begnis Heron Sergio Moreira , Mozzato Anelise Rebelato
Published: December 2018

Este ensaio aborda a estratégia de intercooperação e fusão de redes empresariais sob a perspectiva sociológica da aprendizagem da rede. A cooperação entre redes consiste em uma estratégia para acelerar o crescimento e buscar a consolidação. No entanto, sua execução depende de um processo de aprendizagem da rede, em que as empresas participantes aprendem enquanto grupo sobre a necessidade de cooperar com outras redes. Com base no processo de aprendizagem da rede, o ensaio apresenta e discute um framework para analisar a intercooperação e a fusão de redes empresariais, salientando os episódios de aprendizagem que ocorrem tanto na implementação como na consolidação da estratégia. São apresentadas premissas e três proposições que permitem analisar o contexto, o conteúdo e o processo da aprendizagem da rede. O framework contribui para a compreensão do fenômeno da aprendizagem da rede e como esta interfere na estratégia de intercooperação e fusão de redes.

Published: December 2018

A governança corporativa é composta de um conjunto de mecanismos que buscam maximizar a geração de valor, no longo prazo, para as empresas. No Brasil o tema ganha relevância e destaque acadêmico a partir do ano de 2006 em virtude da aprovação da Lei Sarbanes Oxley, em 2002 nos Estados Unidos da América (EUA). O propósito deste trabalho consistiu em avaliar a produção cientifica no Brasil sobre a temática governança corporativa para o período compreendido entre 2010 a 2016. Diante disso, realizou-se uma pesquisa bibliográfica e bibliométrica, tendo como base dados a base da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) e Scientific Periodicals Electronic Library (Spell), com a aplicação das três Leis da bibliometria, sendo elas: Lei de Bradford, Lei de Lotka e Lei de Zipf, no intuito de analisar a disseminação das pesquisas sobre a temática. Os resultados apresentaram uma boa produção cientifica por periódicos, entretanto o presente estudo não conseguiu constatar a validação da Lei de Lotka, uma vez a produção se encontra bastante pulverizada. Além disso, a Lei de Zipf foi aplicada sobre os títulos e palavras-chave dos artigos que analisados, constatando-se que os termos governança corporativa, estrutura, análise e desempenho são alguns dos termos mais utilizados na produção cientifica estudada.
Narrativa de humor e estilística do horror no SBT: análise da câmera escondida Menina Fantasma Ataca no Metrô
Authors: Hergesel João Paulo , Ferraraz Rogério
Published: December 2018

O principal objetivo das pegadinhas na televisão é provocar o riso no espectador, nem que para isso seja necessário impactar o participante por meio do susto. Esse fenômeno tem sido notado com frequência na cultura audiovisual, sobretudo nas Câmeras Escondidas produzidas pelo SBT para o Programa Silvio Santos. Dentre as criações de maior repercussão pós-exibição, encontram-se as protagonizadas por Anna Lyvia Padilha, atriz que dá vida à personagem Menina Fantasma. O presente trabalho tem por missão analisar, à luz da Estilística, a narrativa de humor – que se constrói com auxílio da estilística do horror – na câmera escondida Menina Fantasma Ataca no Metrô, buscando compreender como ocorre a hibridização de gêneros no produto.
Faça o que digo, mas não faça o que eu faço: a Comunicação Pública anunciada pela TV Brasil e sua perspectiva pós-dissolução do Conselho Curador da EBC
Authors: Coutinho Iluska , Falcão Luis Felipe , Almeida Pedro Ivo Nunes
Published: December 2018

O presente trabalho pretende identificar a mudança da perspectiva democrática da TV Brasil, vivida no início deste ano. O canal, ligado a Empresa Brasil de Comunicação, inaugurado em 2008, ao longo do tempo em que está no ar buscou se aproximar dos ideais de pluralidade e diversidade que deve ter a comunicação pública. Entretanto esta realidade se alterou pós-dissolução do Conselho Curador. A medida adotada pelo Governo Federal representa um retrocesso no amadurecimento não só de um canal efetivamente público mas também de toda uma construção social da TV Pública ao longo de 50 anos. Por meio da análise da materialidade audiovisual de vídeos que tratam das questões ligadas ao conceito de TV pública, concessões de canais e regulamentação além de revisão bibliográfica, tentaremos identificar o quê, na anunciação em que a TV Brasil se define, já não corresponde aos ideais de TV pública.

Salvação Integral na América Latina: breve ensaio bíblico-teológico a partir da Teologia da Missão Integral
Authors: Sanches Sidney Moraes
Published: December 2018

A Salvação é a palavra que anima a prática evangelizadora e pastoral das igrejas evangélicas na América Latina, particularmente, no Brasil. Portanto, é crucial o entendimento do seu significado. Primeiro, introduziremos a maneira como a salvação é representada nos textos bíblicos como a provisão da parte de Deus de um shalom para a sua criação. Depois, indagaremos como a Teologia da Missão Integral aborda a salvação na América Latina em resposta às condições reais de vida de seus povos. Por fim, atualizaremos esse esforço da Teologia da Missão Integral, discorrendo sobre como falar de salvação com a imagem bíblica de shalom, a partir de uma Soteriologia narrativa contextualmente latino-americana.
Hvordan forstår lærere utfordringer i praksisopplæringen? En studie av eksamenstekster
Authors: Engvik Gunnar
Published: December 2018

Hensikten med artikkelen er å undersøke hvordan deltakere i en videreutdanning for praksislærere i en videregående skole forstår utfordringer i praksisopplæringen. I artikkelen besvares to forskningsspørsmål: Hvilke utfordrende tema beskrives i eksamenstekstene? Hvilke tiltak identifiseres i diskusjonen om utfordrende tema i eksamenstekstene? Artikkelens utgangspunkt er en skolebasert videreutdanning gjennomført i vårsemesteret 2016 ved én av NTNUs universitetsskoler. Tematiske analyser av eksamenstekstene identifiserte fire utfordrende tema: klasseledelse, innsikt i skolekonteksten, relasjonen praksislærer praksisstudent og etiske dilemma. Diskusjonen rundt tiltak kan grupperes i fire tolkende koder: kommunikasjon, kartlegging av praksisstudentens livsrom, utvikling av praksislærerens kompetanse, og utvikling av praksisstudentens kompetanser. Deltakernes forståelse av utfordringer i praksisopplæringen knytter seg til to funn: 1) Betydningen av å utvikle et språk for å samtale med praksisstudenter, kolleger og lærerutdanningsinstitusjoner om erfaringer relatert til praksisopplæringen. 2) Temaer i praksisopplæringen som inngår i kulturelle-diskursive forhold (det semantiske rommet) og i makt (det sosiale rommet) er avgjørende for en profesjonell praksisopplæring.

 

The purpose of the article is to investigate how participants in a further education for internship teachers in a high school understand challenges in practice training. The article answers two research questions: What challenging topics are described in the exam texts? What measures identified in the discussion of challenging topics in the exam texts? The article's starting point is a school-based further education completed in the spring semester of 2016 at one of NTNU's university colleges. Thematic analyzes of the exam texts identified four challenging topics: Classroom management, insight into the school context, the relationship of practice teacher-practice student and ethical dilemma. Discussion of measures is divided into four interpretative codes: Communication, mapping of the student's living space, developing the teacher's competence, and developing the student's competence. Participants' understanding of challenges in practice training relates to two findings: 1) the importance of developing a language for conversation with practicum-students, colleagues and teacher education institutions about experiences related to practice training. 2) Themes in practice training that are part of cultural-discursive relationships (the semantic space) and in power (the social space) are essential for a professional practice training.
Investigation of the effect of consolidation on cement flow behaviour
Authors: Turki Djamel , Saidani Messaoud , Belarbi El-habib , Fatah Nouria
Published: December 2018

One of the main problems affecting the flow of cement bulk powder is the formation of cohesive arching at the outlet of the hopper, causing blockage of the silo opening and bridge formation. A simple concept is established which outlines these complications. In this context, the interactions of particles lead to a high degree of consolidation of the cement powder and an increase of adhesion force due to the small size and the large surface area of the cement particles. The results from the consolidation test and the flow properties (cohesion) show that the cement powder flow is mainly controlled by internal forces (Van der Waals and adhesion forces) and external forces. These forces have a direct influence on the powder structure, leading to a variable packing behaviour. Since the problem is attributable mainly to interparticle forces, before storage of the cement powder in the silo, the powder should be fluidised with air at a high velocity to disintegrate the cohesive structure and to overcome this undesirable property of cement flow.
Calculation of the overturning wind speed of large road vehicles at exposed sites
Authors: Baker Chris J. , Soper David
Published: December 2018

High-sided vehicles are particularly vulnerable to high wind conditions and at sites that are regarded as vulnerable, a range of vehicle restrictions are imposed in high winds. These may include vehicle speed reductions or complete restrictions on the movement of different categories of vehicle at different wind gust speeds. This paper builds on earlier work that has been carried out and seeks to develop a simple but conservative method that can be used to specify vehicle restriction strategies. This is based on a collation of a wide range of data for aerodynamic rolling moment coefficients that allows a simple parameterisation to be developed. This is then used in an overturning model to develop a non-dimensional relationship between overturning gust speed and vehicle speed. The parameter used in the non-dimensionalisation is a characteristic wind speed that is a function of vehicle weight and geometry, and effectively specifies the vulnerability of the vehicle to overturning in high winds. Dimensional relationships between overturning gust velocities and vehicle velocities can thus be derived for different vehicle types and used to develop site-specific vehicle restriction methods.
Estimativa da Idade Baseada na Mineralização Dentária Utilizando o Método de Nicodemo, Moraes e Médici (1974) em População do Sul da Bahia
Authors: Victoria Almeida Oliveira Furtunato  , Giselle Boaventura Barros Souto  , Tatiana Dantas Piana
Published: December 2018

Dentre as áreas de competência de atuação do perito odonto-legal está a identificação humana. A estimativa de idade é uma das pesquisas mais utilizadas para identificação dos indivíduos, podendo ser realizada tanto em vivos, quanto em mortos. Os elementos dentários são considerados excelentes meios a fim de se estimar idade, uma vez que possuem maior resistência a alterações químicas, físicas, além de enfatizar a peculiaridade de cada indivíduo ao apresentar características morfológicas exclusivas. O objetivo desse trabalho é verificar a aplicabilidade da metodologia de estimativa da idade proposta por Nicodemo, Moraes e Médici (1974) com base na mineralização dos dentes, na população do sul da Bahia. Foram analisadas 40 radiografias panorâmicas de acordo com o método proposto, sendo 20 do sexo masculino e 20 do sexo feminino, de idades variando de 72 e 119 meses, sendo posteriormente realizada uma análise comparativa referente aos parâmetros de sexo e faixa etária e à análise comparativa da diferença relativa entre as estimativas produzidas em diferentes etapas do estudo. As amostras obtiveram um alto índice de correlação, com acerto em 80% da amostra masculina e 70% da amostra feminina, sendo um método de efetividade comprovada na população estudada, não havendo diferenças significativas entre as análises realizadas em períodos distintos pelo examinador. Observa-se, portanto, ser uma metodologia acessível, uma vez que pode ser aplicada por cirurgiões-dentistas sem experiência prévia do método, de baixo custo, sugerindo, porém, a inclusão de outras características populacionais e uma maior amplificação etária para verificação dos limites de relevância do estudo.
A presença da lusofonia no espaço epistémico das Ciências da Comunicação: 10 anos de estudos temáticos
Authors: Gradim Anabela , Serra Paulo , Piñeiro-Naval Valeriano
Published: December 2018

Fazer a topologia das publicações de temática lusófona no campo das Ciências da Comunicação nos últimos 10 anos (2007-2017) permitiu caracterizar essa produção científica e constatar que esta vem aumentando, que é uma produção feminizada e essencialmente a duas vozes, onde Portugal e Brasil assumem um papel preponderante, que a bibliografia em Português é dominante, contrastando com o estado da citação na área em geral, e que, a partir das temáticas em foco, a Lusocom emerge como o grande think tank dos Estudos Lusófonos na área das Ciências da Comunicação. “A presença da lusofonia no espaço epistémico das Ciências da Comunicação” é um ensaio exploratório, descritivo, de abordagem quanti-qualitativa, com um universo que compreende as atas dos congressos da Sopcom, Ibercom, e o Anuário Internacional de Comunicação Lusófona editado pela Lusocom, num total de 3.252 artigos dos quais, atendendo à temática, foi selecionada uma amostra de 142 espécimes que constitui a base deste estudo.
Disimular la feminidad, vestirse de masculinidad. Mujeres operadoras de la industria química de Tarragona
Authors: Aguilar-Cunill Carla
Published: December 2018

El sector industrial sigue siendo un entorno laboral fuertemente masculino, tanto porque los hombres siguen siendo mayoría en número como porque la masculinidad sigue siendo la lógica fundamental en sus procesos productivos. Este artículo analiza la situación actual, en que las trabajadoras, aunque son minoría, hace ya años que participan de este entorno laboral. Concretamente, el análisis está centrado en el nivel de las relaciones informales en el espacio de trabajo para entender el papel que mantiene el género en este entorno laboral. Con este objetivo, se realiza un estudio de caso del polo químico de Tarragona, el más importante del sur de Europa, en el que actualmente la fuerza de trabajo femenina es el 15%. El estudio se ciñe específicamente al nivel de operadores/as de planta, los puestos de trabajo de base de la industria, desde los que se controla el proceso químico in situ. Para la investigación, de base cualitativa, se han hecho 14 entrevistas a mujeres que realizan este trabajo, analizadas a través de una perspectiva de género constructivista. La metodología de la investigación en la que se enmarca esta tesis es la investigación-acción, por lo que los resultados aquí presentados también se han devuelto a las informantes en grupos de discusión para su debate y mejora. El principal resultado de este artículo es que, pese a la creciente participación femenina en el ámbito de la industria química, las dinámicas de relación siguen estando marcadas por la masculinidad. Pese a que la entrada de las mujeres se produjo unos veinte años atrás, se siguen detectando resistencias por parte de los trabajadores a la entrada de las mujeres. Estas resistencias se trasladan al plano identitario de las mujeres, quienes experimentan una cierta contradicción entre ser mujer y ser parte del equipo de operadores. Todo ello hace necesario que las mujeres desarrollen estrategias para el día a día en este entorno laboral, en las que utilizan herramientas de género. Para incorporarse mejor a este entorno laboral, las mujeres desarrollan estrategias coincidentes pese a ser individuales, disimulando elementos propios de la feminidad, a la vez que se visten con elementos masculinos. Así intentan escapar de la hipervisibilización negativa que tiene la feminidad en este entorno laboral. Mediante esta investigación, se pone sobre la mesa la importancia de las relaciones informales en el trabajo como espacio de dominación. Su gestión diaria, de acuerdo con los resultados, supone una carga extra de trabajo emocional y de estrés que recae sobre las mujeres.
Nociones de calidad educativa y actitudes de los docentes hacia las tecnologías de la información
Authors: Olaskoaga Jon , Rodríguez-Armenta Carmen Enedina , Marúm-Espinosa Elia
Published: December 2018

Esta investigación reúne evidencia de que existe una relación entre las preferencias del personal académico por los diferentes modos de definir la calidad de la educación superior y su percepción de la utilidad que tienen las tecnologías de la información (TI) en su trabajo. Las pruebas de esta relación se obtuvieron aplicando técnicas de regresión logit a las respuestas de 911 docentes de la Universidad de Guadalajara (México). La evidencia reunida representa una doble aportación: al Technology Acceptance Model (TAM), que contribuye a extender añadiendo una variable que puede actuar como antecedente de la utilidad de las TI, y a la hipótesis del contenido político de los conceptos de calidad de la educación superior.

Recognition of peripherally exposed emotional expressions
Authors: Zhegallo A.V.
Published: December 2018

The study investigates the specifics of recognition of emotional facial expressions in peripherally exposed facial expressions, while exposition time was shorter compared to the duration of the latent period of a saccade towards the exposed image. The study showed that recognition of peripherical perception reproduces the patterns of the choice of the incorrect responses. The mutual mistaken recognition is common for the facial expressions of a fear, anger and surprise. In the case of worsening of the conditions of recognition, calmness and grief as facial expression were included in the complex of a mutually mistakenly identified expressions. The identification of the expression of happiness deserves a special attention, because it can be mistakenly identified as different facial expression, but other expressions are never recognized as happiness. Individual accuracy of recognition varies from 0.29 to 0.80. The sufficient condition of a high accuracy in recognition was the recognition of the facial expressions using peripherical vision without making a saccade in the direction of the face image exposed.

Authors: Moroshkina N.V. , Ivanchei I.I. , Tikhonov R.V. , Karpov A.D. , Ovchinnikova I.V.
Published: December 2018

The article presents a database of women’s faces for research in the field of social perception. Each of 55 models was photographed full-face under four conditions: with a neutral or smiling face with hair up or down. The database includes the results of facial morphometry (relative positions of homologous points), expert ratings of appearance style, scores of perceived intelligence and attractiveness. The peculiarity of the database is that, unlike the others, we preserved the natural style featured on the models: clothes, jewelry, and makeup. The database was approbated in the study of physiognomic and appearance style predictors of perceived intelligence and attractiveness. It expands the variety of stimulus images available for researchers and can be used in different studies of social perception.
Features of Volitional Regulation of Komi-Zyryans and Russians
Authors: Shlyapnikov V.N. , Avdeeva O.V.
Published: December 2018

The results of a cross-cultural study of volitional regulation in Komi-Zyryans and Russians are presented. Two samples of 100 representatives of Komi (Syktyvkar) and 100 representatives of Russian (Moscow) was compared. The samples were balanced by gender, age and other socio-demographic characteristics. To diagnose the individual characteristics of volitional regulation of the respondents, the following methods were used: “Action-control scale” by Yu. Kuhl, “Questionnaire for revealing the expression of self-control in the emotional sphere, activity and behavior”, self-evaluation of volitional qualities. The significant differences between Komi-Zyryans and Russians in behavioral (p=0,05) and social self-control (p=0,01), self-appraisals of volitional qualities: disciplined (p=0,01), persistent (p=0,01), strong-willed (p=0,05), initiative (p=0,05), restrained (p=0,05), patient (p=0,01), stubborn (p=0,01), calm (p=0,01), attentive (p=0,01) were showed. The obtained results confirm the hypothesis about the presence of cross-cultural differences in the parameters of volitional regulation and confirm the ideas of the volition as a higher mental function.

Los lenguajes del ciclismo y la novela El Alpe D’Huez de Javier García Sánchez = The languages of Bicycling and Javier García Sánchez´s novel El Alpe D´Huez
Authors: Ayuso Collantes Clara
Published: December 2018

En el bicentenario de la aparición de la bicicleta, este trabajo quiere ser una indagación en el lenguaje sectorial del ciclismo, más allá del que aparece en las crónicas periodísticas, que es el único que hasta ahora ha contado. Para ello, se analiza una novela que es un compendio ciclista. En El Alpe d´Huez (1994) de Javier García Sánchez se entrecruzan diversos códigos léxicos especializados a los que la creación literaria potencia con otro más abarcador: el mítico, de hondas raíces antropológicasOn The bicentenary of the bicycle’s origin, this work strives to be an inquest into the sectoral language of cycling, apart from that in the journalistic chronicles, which is the only one that has mattered so far. For that purpose, we will analyse a novel which is a cyclist compendium. In the Alpe d’Huez (1994), by Javier García Sánchez, different specialised lexical codes intertwine, and literary creation enhances them with yet another code, a more comprehensive one: the mythical one, with deep anthropological roots.
Metodologías de corpus en el análisis de textos literarios en lengua española: el ejemplo de Pérez Galdós = Some kinds of corpus analytic test in Spanish literature: the case of Pérez Galdós
Authors: Nieto Caballero Guadalupe
Published: December 2018

En este artículo se aborda el potencial de los estudios de corpus en el análisis de textos literarios en lengua española. Para ello se ha utilizado la obra narrativa de Pérez Galdós, que ha sido comparada con un corpus de referencia formado por novela realista española. El estudio se centra en la proyección del discurso por parte de los narradores del universo galdosiano y en las implicaciones estilísticas de aspectos tradicionalmente desapercibidos para la crítica.This article looks into the potential of corpus approaches in the analysis of literary texts written in Spanish. To do so, the fictional narratives of Pérez Galdós have been scrutinized. They have been first compared to a reference corpus made up of nineteenth-century canonical, later to analyze them separately. The analysis has focused on the reporting of characters’ verbal discourse by the narrators of Galdós’s novels and on stylistically significant aspects hitherto unnoticed.
Procedimientos de mímesis de la oralidad en el teatro español del siglo XVIII = Mimetic procedures of orality in the Spanish 18th century drama.

Published: December 2018

El presente trabajo examina una selección de obras teatrales del s. XVIII en las que concurren interrupciones, robos de turno, solapamientos, reinicios o dubitaciones que imitan la planificación sobre la marcha propia del discurso oral espontáneo. El análisis de estos fenómenos, en los que se reconoce un especial perfeccionamiento de la mímesis de la oralidad con respecto a épocas anteriores, pretende contribuir a mejorar nuestro conocimiento tanto sobre la historia de la oralidad fingida en español como sobre la lengua del siglo XVIII.This work takes a deep look into a sample of theater pieces from the 18th century in which interruptions,stealing of floor, overlaps, reboots and hesitations try to mimic ongoing planning in spontaneousoral speech. Our analysis shows a remarkable improving in oral mimesis in comparison with preceding periods and tries to make a contribution to a better understanding both of the history of pretended orality in Spanish and of 18th century Spanish language.
A legitimidade do controle de constitucionalidade pelo Senado Federal a partir de sua origem francesa
Authors: Calil Mário Lúcio Garcez , Franzé Luís Henrique Barbante
Published: December 2018

A preservação da força normativa da Lei Maior é uma necessidade em um Estado Constitucional. Diante disso, é indispensável o aprimoramento dos mecanismos de controle de constitucionalidade, de modo a aumentar sua eficiência e seu campo de atuação. Sabe-se, além disso, que o Poder Legislativo é o principal responsável pela concretização das disposições constitucionais, mediante obediência às disposições materiais e procedimentais do Texto Constitucional. Assim, o objetivo deste trabalho é o controle de constitucionalidade pelo Parlamento nacional, tanto no que se refere ao processo legislativo quanto às disposições em si, enquanto parte fundamental do próprio processo legislativo, por intermédio, inclusive, das denominadas Comissões Parlamentares, a partir da experiência francesa, mediante pesquisa bibliográfica e documental. O presente trabalho é justificável, tendo em vista que, evidentemente, a entrada de disposições legais inconstitucionais em qualquer ordenamento jurídico ocasiona o enfraquecimento da força normativa da Constituição Federal, bem como demanda atuação repressiva do Supremo Tribunal Federal. Conclui-se pela legitimidade do controle preventivo de constitucionalidade pelo Senado.
Experimental research on the development of an “oxygen (gas) + kerosene” – fueled thruster
Authors: Salich V. L.
Published: December 2018

The results of experimental studies of a rocket engine fueled by gaseous oxygen-kerosene with a thrust of 20N, with four workflow variants are presented. The first version of the engine with the UVK-1 chamber demonstrated low energy characteristics, there were misfires. The engine with the UVK-2 chamber differed from the UVK-1 in that the fuel injector had a large geometric characteristic due to the increased diameter of its nozzle. The UVK2 provided stable start without misfiring and slightly improved energy characteristics. In the UVK-3 version, the energy characteristics were improved by decreasing the proportion of the oxidizer supplied to the curtain of internal cooling. The increase in the length of the cylindrical part of the combustion chamber (variant UVK-4) did not lead to the expected increase in energy characteristics. This is probably due to the peculiarity of the location of the cooling curtain assembly. In the course of research it was also found that the parameters of the igniter electric discharge have a significant influence on the nature of the chamber working process during the starting period. It is expedient to search for ways of further improving the energy characteristics in the direction of reducing the oxygen flow to the cooling curtain in the UVK-3 version with the nozzle material replaced by Nb5V2MC.
Comparative analysis of fuel distribution downstream of the gas-dynamic flame holder with various methods of injection
Authors: Tretyakov V. V. , Sviridenkov A. A.
Published: December 2018

The article deals with the problems of atomization and distribution of liquid fuel in a swirling flow downstream of the front-end gas-dynamic stabilizer designed for the use in gas turbine engine combustion chambers. The task is to compare the distributions of droplet-liquid fuel in the wake of the stabilizer when the fuel is injected from the side and end surfaces of the device in question. It is shown that the calculations performed according to a stationary model are qualitatively different from the non-stationary ones in both fuel supply options. However, in the first approximation, the distributions of liquid droplet fuel fed from the side and end surfaces of the stabilizer are similar. An experimental study of the spray characteristics was conducted by the Shadowgraphy method of diagnosing droplet-air fluxes with the fuel supplied at an azimuthal angle of 45 from the side surface of the gas-dynamic stabilizer. It is shown that if the fuel is injected at an angle it leads to a change in the velocity distribution in the wake of the stabilizer, and the flow swirl opposite to direction of azimuth fuel supply expands the spray pattern.
Construction of limitation diagrams for truss core stiffness and strength parameters
Authors: Gainutdinov V. G. , Gainutdinova T. Yu. , Abdullin I. N.
Published: December 2018

A truss-core sandwich panel is a promising load-bearing element of lightweight high-stiffness structures. The use of this element in load-bearing structures makes it necessary to know its mechanical and strength characteristics depending on the structure and properties of a typical core cell. Currently, the available results are not sufficient to assess the strength due to the complexity of taking into account all the features of the loading of the core structure in the form of repeated pyramidal and tetrahedral unit cells most common in the production of lightweight truss cores. In the research of the strength properties of a unit cell, it is assumed that the destruction of the truss structure may occur when the yield stress in the material of the core is exceeded or if buckling takes place. The scheme of destruction of the truss structure in the cell will depend on the combination of unit cell equivalent stress values. The critical core buckling stress is usually less than the yield stress. Therefore, when co block diagrams of equivalent stress constraints are constructed, one can observe a rather complex picture of the change in the limit values depending on the azimuthal angle in the plane of the cell base. To analyze limitation diagrams, the easiest way is to introduce a parameter determined by the ratio of the critical buckling stress to the magnitude of the yield stress of the core material. In this case the limitation diagrams will not depend on the specific critical absolute values of stresses, but on their relationship; the nature of the diagrams will not depend on the density of the core. The design parameters of the core are determined on the basis of the construction of other diagrams for the given (required) values of generalized compressive stiffness, transverse shear, generalized critical compressive stresses and transverse shear of a unit cell of the sandwich structure which depend on the relative density of the truss core. The combination of these two constraint diagrams gives a more complete picture of the degree of optimality of the truss core design parameters.

Published: December 2018

The task of optimizing control methods in order to maintain key performance parameters of a gas turbine engine throughout the engine service life is considered. Variations in the performance characteristics of engine components in the process of operation are analyzed. To study the effect of deterioration on the engine parameters, a mathematical model of a turbofan engine was modified. The influence of degradation of the gas turbine engine components on its key performance parameters with traditional control methods is assessed. An engine control method using the value of thrust calculated in the on-board engine mathematical model is proposed. This method makes it possible to compensate for the negative effect of the components performance degradation due to their wear. The results of mathematical modeling of the operation of a turbofan engine in steady-state and transient modes are given. The results confirm the effectiveness of the proposed control method: despite the engine deterioration the original thrust value is maintained due to the available gas temperature margin in the combustion chamber

We study the problem of determining time-optimal control of in-plane rendezvous transfer of spacecraft with low transversal thrust. We use the Pontryagin maximum principle to determine the optimal control program. Motion is considered in the vehicle centric system with linearized equations. We recognize secular and periodic components of relative motion. Motion control is accomplished by the reversal of the thrust acceleration component. We study the general problem controlling the periodic and secular components at the same time (joint optimal control program). Also we study partial problems determining separate control programs for secular and periodic components of planar motion. Solving partial problems made it possible to determine the structure of the joint optimal control program. We found that the adjustment of secular motion components contains no more than two phases of constant acceleration. The adjustment of periodic motion components consists of a sequence of boost and deceleration phases, the number of which in a single pass does not exceed three.
Optimization of fuel distribution in the afterburner of a gas turbine engine
Authors: Nelyubin V. R.
Published: December 2018

The use of 3-D simulation programs and in particular NX and ANSYS simulators brought the design and fine tuning of gas turbine engine combustion chambers to the next level, as it allows improving the performance (increased combustion efficiency, reduced radial and circumferential non-uniformity of the total gas temperature), as well as determining the weak points of the structure. The article analyzes the flow of fuel jets from the finger sprayers of the afterburner of the combustion chamber of a gas turbine engine. The problem of optimizing the distribution of fuel is formulated: the fuel at the exit of the flame tube is to be evenly distributed by varying the diameters of the holes in the fuel manifolds. Restrictions are imposed on the optimization problem the supply of fuel to the peripheral zone at the outlet of the afterburner is reduced by a factor of five. The optimization effect is verified by comparing the fuel combustion efficiency in the case of standard fuel distribution with the optimized distribution option using the NX and ANSYS 3-D simulations. As a result, we observe an increase in combustion efficiency in all afterburner modes of engine operation.

Background and purpose: Few studies have been carried out on paternal adaptation and there is no comprehensive definition and theory about paternal adaptation in men. This study aimed to extract the concept of paternal adaptation in men and factors affecting it based on qualitative research conducted on paternal experiences.Materials and Methods: This research was a systematic review and meta-synthesis, including 10 articles, that combined the findings of qualitative research related to men`s experiences of transition to fatherhood, using meta-ethnographic method.Results: Findings of this study were categorized into three themes including representations and signs of paternal adaptation, paternal adaptation facilitators and paternal adaptation obstacles. Based on the study findings, parental satisfaction, understanding paternal transition and development, being capable of fulfilling paternal responsibilities, and being capable of handling the current situation were found to be the representations and signs of paternal adaptation. Adaptation facilitators included attempt to manage present situation, cooperation in the child rearing, time lapse, use of educational resources, readiness to become a parent, utilization of support resources, and parental leave. On the other hand, adaptation obstacles were found to be as follows: damaged parental relationship, paternal role ambiguity, expectations above the father's abilities, lack of time for oneself, damaged marital relationship, occupational concerns, insufficient social support, false myths and misbeliefs, and financial problems. Conclusion: Based on the findings of the current study, enhancing fathers' parenting knowledge and skills, creating educational opportunities, supplying support resources, preparing the setting for father`s continued presence and participation in the family, and offering paternal models to the society may facilitate fathers' paternal adaptation.
O diálogo crítico nas relações educativas imbricado aos movimentos de ação-reflexão

Published: December 2018

A partir de um estudo descritivo crítico, fundamentado em uma pesquisa qualitativa, bibliográfica, adensada pelo pensamento educacional de Paulo Freire, teve-se como intenção refletir sobre os pressupostos que demonstravam premente o exercício do diálogo crítico nas relações educativas, bem como estudar a sua relação com os movimentos de ação-reflexão diante dos desafios que enfrenta a escola contemporânea. Na primeira parte do texto, resgatam-se nas obras freirianas, as quais abordam o assunto, a importância do exercício do diálogo, cuja raiz está na educação popular, como relação em que os seres humanos pronunciam e modificam o mundo. A partir dessa compreensão, esse mesmo mundo pronunciado volta-se problematizado aos sujeitos, gerando novas ações no contexto histórico. Na segunda parte, aproxima-se a discussão dos desafios vividos pelos seres humanos no momento contemporâneo, em que tanto educadores quanto educandos estão tomados por fragmentos impostos pelos modelos de produção e consumo vigentes. Nessas condições, fez-se objetivo neste estudo elaborar aproximações e distanciamentos entre a educação popular e a educação formal, fundamentados na razão de que o educando aprende quando, pelo conhecimento científico trabalhado, ressignifica seus saberes do cotidiano e consegue gerar ações que venham a provocar transformações no meio em que está inserido.

The study was undertaken to determine the serum concentration of an active form of transforming growth factor-bl (TGF-bl) and the functional status of leukocytes in patients with Stage II hypertensive disease (HD) and to assess the pathogenetic value and capacities of correction of detected changes with the angiotensin-converting enzyme (ACE) inhibitor quinapril. Materials and methods. Thirty patients with Stage II HD and 17 apparently healthy individuals were examined. The data of ultrasound studyofthe heart, radial and carotid arteries, the functional activity of leukocytes and the concentration of (TGF-bl) in the serum were assessed. Of them, 15 patients with HD were reexamined during treatment with quinapril (accupro, Pfizer, USA) in a daily dose of 10-40 mg for 12 weeks. Results. The study established an increase in the elevated serum levels of TGF-bl of hypertensive patients with HD and its association with the mass of the left ventricular myocardium, with the thickness of an intima-media complex of the common carotid arteries, and with endothelial dysfunction. A relationship is shown between the concentration of TGF-bl and the functional activity of leukocytes: elevated peripheral leukocytes, the adhesive capacity of neutrophils, the lymphocytic expression of the antiapoptic protein Bcl-2 and Fas-receptors. With quinapril treatment, a 10-mm Hg or more reduction in 87% of the patients was attended by the lower adhesion of neutrophils to the endothelium, with elevated Bcl-2-negative and Fas-positive lymphocytes. Conclusion. The changes in the serum levels of TGF-bl are associated with lesions of target organs and with the activation of leukocytes in HD. The decrease in leukocytic functional activity during therapy with quinapril did not depend on the antihypertensive effect of the drug.

Published: December 2018

In chloralose anesthetized and paralyzed spontaneously hypertensive rats (SHR) a somatosympathetic reflex in the cervical sympathetic trunk elicited by a single electrical shock to forelimb afferent fibres in the median nerve was recorded. It has been shown that the somatosympathetic reflex consists of two responses and following silent period. The А-response evoked by the somatic myelinated afferent fibres stimulation, and C-respon.se elicited by the both stimulation of myelinated and unmyelinated afferent fibres. The silent period occurred with the myelinated fibres stimulation. Its duration was proportional to the electrical shock amplitude. The А-response consisted of four waves, the three of them formed early and late responses.
