Characterisation of a subaqueously deposited silt iron ore tailings
Authors: Reid D. , Fanni R. , Koh K. , Orea I.
Published: October 2018

A geotechnical investigation was carried out to characterise a subaqueously deposited, primarily silt, iron ore tailings. Piezocone penetration tests (CPTu) were carried out followed by piston tube sampling at a selected target depth. Piston samples provided measures of in situ density (by means of gravimetric water content), and supplied material for reconstituted and intact laboratory testing. Reconstituted samples prepared using moist tamping (MT) for determination of the critical state locus (CSL), along with intact specimens, were both tested. The potential existence of layering within the recovered specimens was also assessed, indicating near-homogenous samples. The laboratory testing of intact specimens suggested that they appeared to tend towards the same CSL as that obtained from reconstituted loose MT specimens. This tentative result differs from some previous comparisons – with the agreement seen in this case being suggested to primarily result from a lack of layering. In situ state as inferred from both CPTu data and comparison of tube densities to the CSL suggested a loose state.
Design for accessibility for floating structures
Authors: East Matthew
Published: October 2018

This paper focuses on recent works completed by GHD Pty Ltd in 2016 for the design of accessible ferry terminals and looks at the techniques utilised and designs implemented to develop terminals with the intent to provide inclusive unassisted all-tide access. To achieve this, the design looked at the pontoon and gangway (brow) configuration and ways to achieve compliant slopes, along with the engagement of an access consultant and workshops with a sample of the user group. The works also focused on lessons and research from previous designs, the use of visual aids, including three-dimensional walkthrough models and virtual reality goggles to present the design to the client and user group, and design solutions required to achieve the necessary compliance. This paper provides a summary of these key findings regarding accessible slopes, design tide ranges, terminal orientation, sight lines, provision of landing and rest areas, dedicated waiting areas, lighting, walkway width and ergonomics.

Evaluating the condition and stability of coastal cliffs and assessing longevity of significant overhangs and undercuts in an active marine environment is a challenge. As part of cliff management studies undertaken for the Coastal Zone Management Unit of the government of Barbados, a programme of innovative cliff profile mapping was conducted around the island of Barbados. A combination of land-based field mapping information and fixed wing aircraft collected high-resolution LiDAR imagery was utilised for cliff geometry assessments, supplemented for specific cliff profiles by fill-in high-precision three-dimensional (3D) digital terrestrial imagery, captured by low level wide wingspan UAV drone flights. Comprehensive photogrammetric processing of this imagery, combined with detailed geographic information system software evaluation of the collected point cloud data, allowed generation of full 3D wireframe digital terrain and digital elevation models (DTMs and DEMs). Multiple representative cliff areas around the island were identified, allowing thorough 3D stability assessment to be accomplished of key problematic areas using Flac3D. Vertical cross-section profiles were also cut so that undercut and notched cliffs could be analysed in detail in two dimensions using Voronoi tessellation approaches applied within the universal distinct element code UDEC as a means to replicate the characteristics of the vuggy coralline limestone cliffs.
Pull-out tests on handcrafted headed studs
Authors: de Oliveira Dênio Ramam Carvalho , de Oliveira Andrielli Morais , da Costa Viviane Gatti
Published: October 2018

The aim of this paper is to contribute towards better understanding of the behaviour of site-welded headed studs embedded in normal-weight concrete. The axial failure loads of these studs estimated by design codes and other calculation methods are conservative and inaccurate for concrete cone detachment. The concrete tensile strength and embedded length of the steel shank are believed to be the most influential factors on the final pull-out resistance of headed studs. In an experimental programme, ten headed studs with varying head thickness were pulled out from concrete blocks of strength 25 MPa or 35 MPa. The failure loads, failure modes and steel yield loads were used as parameters to verify the efficiency of the studs and to evaluate which design methodology gave estimated final resistances closest to the experimental values. Two collapse types were observed: one was located along the shank when the applied load exceeded the steel tensile failure load while the other was in the concrete and occurred when the applied load exceeded the concrete ultimate tensile strength, creating a conical failure surface. The two head thicknesses were found to be satisfactory and the theoretical loads underestimated the concrete tensile strength.

Published: October 2018

In the present research, a novel cost-efficient chromium (Cr)–aluminum (Al)–carbon (C) target hot-pressed at 650°C with chromium:aluminum:carbon = 2:1:1 (molar ratio) was applied to fabricate chromium aluminum carbide (Cr2AlC) coatings by the arc ion plating method at room temperature and subsequent annealing. Scanning electron microscopy, X-ray diffraction and transmission electron microscopy were used to characterize the coatings and the target. The results showed that the chromium–aluminum–carbon target mainly comprised chromium, carbon and chromium aluminum compound (Cr9Al17). By arc ion plating with the hot-pressed chromium–aluminum–carbon target and subsequent annealing at 620°C, polycrystalline chromium aluminum carbide coating with minor chromium carbide (Cr3C2) was obtained. The as-prepared chromium aluminum carbide coating was dense and crack-free, and there existed macroparticles in the coating. Transmission electron microscopy observations revealed that the as-prepared chromium aluminum carbide coating exhibited a multilayer structure vertical to the growth direction. The coating possessed hardness and adhesion strength of 8·8 ± 0·8 GPa and 42 ± 17 MPa, respectively, which could meet the basic requirement of high-temperature protective coating.

Hysteresis via Endogenous Rigidity in Wages and Participation
Authors: Doniger Cynthia L. , López-Salido J. David
Published: October 2018

We document that the past three “jobless” recoveries also featured asymmetries in labor force participation and labor compensation, with each falling to new lows during each cycle. We model these asymmetries as resulting from a strategic complementarity in firms’ wage setting and workers’ job search strategies. Strategic complementarity results in a continuum of possible equilibria with higher-wage equilibria welfare dominating lower-wage equilibria. Assuming that no economic agent deviates from an existing strategy unless deviation is a unilateral best response, the model exhibits (1) periods of endogenous rigidity in wages and participation, (2) persistent changes in wages, participation, and output in response to transitory movements in labor productivity, (3) sluggish recoveries including both a “jobless” phase, in which productivity recovers while unemployment remains elevated, and a “wageless” phase, in which employment recovers but wages remain depressed. Calibrating the model suggests that the U.S. unemployment rate may need to fall to around 3 percent before labor compensation recovers to pre-Financial Crisis levels.
Measuring the Implementation of the FSB Key Attributes of Effective Resolution Regimes for Financial Institutions in the European Union
Authors: Coleman Nicholas , Georgosouli Andromachi , Rice Tara
Published: October 2018

There are lingering concerns about the health of European banks and extensive market commentary about whether post-crisis regulatory reforms in Europe have adequately addressed these concerns. In June 2012, European policymakers released the broad outlines of a proposal for a "European banking union" to strengthen the banking sector and help assuage concerns of investors and depositors, however, uncertainty remains regarding how the new EU bank resolution regime, the Bank Recovery and Resolution Directive (BRRD), will work in practice. This paper addresses whether the BRRD has fulfilled the requirements of the FSB Key Attributes for Resolution Regimes, which many take to be the gold standard bank resolution framework. We find that the BRRD diverges from the FSB Key Attributes or allows variation at the Member State level in multiple areas. The majority of these variations point to slight inconsistencies with the FSB recommendations. That said, some variations may have a larger impact than others.
Оценка распространенности злокачественных новообразований в России с применением модели заболеваемость-смертность
Authors: Турсун-заде Рустам Тимурович
Published: October 2018

В данной работе предпринимается попытка оценки непубликуемых производных показателей онкологической заболеваемости и смертности в населении РФ с использованием таблиц множественного выбытия – популяционной модели рака Д. Дюшен в сложившихся условиях ограниченной доступности медико-демографических данных. Смоделированные таким образом показатели (средний возраст заболевания злокачественными новообразованиями (ЗНО), средняя ожидаемая продолжительность болезни, распространенность ЗНО в населении и средний возраст смерти от ЗНО) позволят определить, происходит ли в России рост распространенности ЗНО и является ли этот рост результатом экспансии заболеваемости ЗНО (понимаемой как среднее увеличение времени, прожитого в состоянии нездоровья, обусловленного этим заболеванием)?

Показано, что в России наблюдается сонаправленный рост среднего возраста заболевания ЗНО и среднего возраста смерти от ЗНО с приматом последнего. Результатом этих изменений является увеличение среднего числа лет, прожитых с ЗНО, а также рост распространенности ЗНО в населении РФ. Отмечены локализации с наибольшим и наименьшим наблюдаемым ростом распространенности ЗНО, а также локализации исключения из выраженной тенденции к этому росту.

На основании проведенного анализа можно утверждать, что в России происходит экспансия заболеваемости ЗНО, выраженная в увеличении среднего числа лет, прожитого в состоянии неполного здоровья. Исключением является локализация «ЗНО губы, полости рта, глотки и пищевода» (С00-С15) у женщин, для которой отмечается компрессия заболеваемости, выраженная в сокращении числа лет, прожитых с ЗНО.
Армяне России – геодемографические тенденции прошлого, современные реалии и перспективы
Authors: Сущий Сергей Яковлевич
Published: October 2018

В статье анализируется количественный рост, пространственная динамика, гендерная структура и форма расселения армянского населения России в XVIII-XX веках. Изучено демографическое соотношение крупнейших региональных сообществ на разных этапах их развития. Определены основные исторические периоды геодемографической динамики армян России.

Первый может быть обозначен как «южнороссийский» (вторая треть XVIII века – 1920-е годы). На его протяжении подавляющая часть армянского населения России концентрировалась в пределах южного макрорегиона. На втором этапе (середина 1920-х – первая половина 1980-х гг.) армяне расселяются почти по всей территории РСФСР, но представляют внутренне слабосвязанные этнические группы. Третий период (вторая половина 1980-х – настоящее время) связан с трансформацией данных групп в развитые региональные общины.

 Три века количественного роста позволили армянам стать к началу XXI века одним из крупнейших народов Российской Федерации. В среднесрочной перспективе (к 2030 г.) при благоприятном сценарии демографической динамики армяне в состоянии занять третью позицию в демографическом рейтинге народов России (следом за русскими и татарами).

Repercusiones del ámbito laboral en la vida familiar de los hombres: un estudio evolutivo
Authors: López Anna , Acedera Amparo
Published: October 2018

El estudio apunta a que una pesada carga de trabajo repercute fuertemente sobre el ámbito familiar del cónyuge y de los hijos, con respecto al propio bienestar. Los hombres de hoy en día se enfrentan a un «dilema invisible» que surge cuando tratan de conciliar el papel de trabajador y la vida y las obligaciones familiares. Estos hombres se muestran insatisfechos con la gestión de su tiempo. Desean disponer de más tiempo para sí mismos, para la pareja, para la familia; pero no consiguen sacar ese tiempo de su situación real. El contexto de trabajo se presenta como una presión continua y una demanda de presencia y de compromiso que hace que estos hombres sean cada vez más dependientes del trabajo. La realidad es que estos hombres, sobre todo los que ocupan cargos directivos, trabajan mucho y el trabajo termina adentrándose en la esfera privada y colonizando el espacio familiar. Asimismo parece que para muchos de estos hombres, el trabajo sigue siendo lo primero y es más importante que la familia.

Las lenguas del espíritu
Authors: Vallverdú i Vallverdú Jaume
Published: October 2018

El contenido de este libro se inscribe en un proyecto de investigación más amplio sobre los llamados «movimientos religiosos carismáticos y extáticos». En primer lugar se presenta el arraigo y desarrollo de la tradición protestante en América Latina y particularmente en México, examinando su diversidad y sus variantes internas en el contexto de los procesos de cambio religioso vividos por este país en las últimas décadas. Se exponen también al respecto las diferentes interpretaciones y controversias en torno al crecimiento evangélico, con sus principales agentes y protagonistas. Posteriormente, se presentan los principios teológicos y de experiencia espiritual del pentecostalismo. Se parte de la descripción de sus creencias, prácticas y esquemas organizativos fundamentales y se incluyen los ejemplos etnográficos de tres iglesias evangélicas de la ciudad de Cuernavaca. Dicha descripción sirve de contextualización general a la ulterior articulación teórica de cada uno de los tres grandes ejes de análisis: la conversión, la experiencia religiosa y el carisma. En su parte final, el libro propone una síntesis comparativa integrando estos tres ejes principales, con el objetivo de avanzar en la comprensión e interpretación de los rasgos estructurales y funcionales que parecen compartir los movimientos de perfil carismático y extático. La reflexión teórica reincide tanto en la dimensión personal y subjetiva de los fieles como en la comunitaria e institucional, ambas estrechamente vinculadas al profundizar en las dinámicas internas de estos movimientos religiosos.
Repercussions of the work environment on the family life of men: a developmental study
Authors: López Puig Anna , Acereda Extremiana Amparo
Published: October 2018

The study points to a heavy workload having strong repercussions on the well-being of the family. Modern men are faced with an invisible dilemma which emerges when they try to reconcile their work with their family obligations. These men are dissatisfied with how they manage their time. They want more time for themselves, for their partners and for their families, but they are unable to find it in their current circumstances. Work is seen as a continuous pressure which requires their presence and commitment and which makes these men more and more dependent on their jobs. The reality is that these men, and particularly those who occupy management positions, spend a lot of time working and their jobs end up making inroads into their private lives and colonizing the family ambit. It also seems that for many of these men work continues to be their number one priority and is more important than the family.
Diagnostic fluidity: working with uncertainty and mutability
Authors: autores Varios
Published: October 2018

Diagnostic procedures are emblematic of medical work. Scholars in the field of social studies of medicine identify diverse dimensions of diagnosis that point to controversies, processual qualities and contested evidence. In this anthology, diagnostic fluidity is seen to permeate diagnostic work in a wide range of contexts, from medical interactions in the clinic, domestic settings and other relations of affective work, to organizational structures, and in historical developments. The contributors demonstrate, each in their own way, how different agents ‘do diagnosis’, highlighting the multi-faceted elements of uncertainty and mutability integral to diagnostic work. At the same time, the contributors also show how in ‘doing diagnosis’ enactments of subjectivities, representations of cultural imaginaries, bodily processes, and socio-cultural changes contribute to configuring diagnostic fluidity in significant ways.
Dissociation of Single Cell Suspensions from Human Breast Tissues v1
Authors: Bai Shanshan , Sei Emi , E. Navin Nicholas
Published: October 2018

This protocol was developed for the human breast cell atlas (HBCA) project to obtain high-viability cell suspensions from freshly dissociated breast tissues from human patients. There are two options for performing this protocol: rapid-dissociation (15-30 min) or exhaustive dissociation (overnight). In our experience the rapid dissociation protocol will provide higher cell viability and better representation of breast cell types, however the total number of cells dissociated may be lower after enumeration. In contrast the exhaustive protocol provides higher cell numbers and maintains good cell viability but may result in skewing of cell type representations over the long time period. The rapid-dissociation protocol was used to generate most of the cell suspensions for the MD Anderson human breast cell atlas project and has been optimized and tested more extensively.

Cost-conscious generation of multiplexed short-read DNA libraries for whole genome sequencing v1
Authors: Jones Ashley , Borevitz Justin , Warthmann Norman
Published: October 2018

Illumina® short-read DNA sequencing has become an integral tool in biology for genome-wide studies. Offering accurate base-pair resolution at the most competitive price, the technology has become widespread. However, the generation of multiplexed DNA libraries remains costly and cumbersome. Here, we present a streamlined cost-conscious protocol for generating multiplexed short read DNA libraries using a transposase from Illumina®. By implementing small volumes that use 1/25th the amount of transposase compared to Illumina® NexteraTM protocols, the cost of library preparation can be significantly reduced, by 1/10th or more. Furthermore, we optimised the protocol to minimise carboxylate bead-based cleanups between steps, further reducing cost, time and DNA input. By developing our own indicies to multiplex nine 96-well plates, up to 864 samples can be placed on a single flow cell. This enables efficient usage of monolithic sequencing platforms that can offer over three terabases of sequencing per flow cell.

Guided literacy instruction: Helping students read multimodal English-medium texts
Authors: Tungka Novalita Fransisca
Published: October 2018

This article reports a phenomenological study investigating the implementation of guided literacy instruction, geared to L2 students in reading multiple texts as the fabric of today’s literacy practice. Guided literacy instruction in this study aimed to promote the role of a student reader as a designer, navigator, interrogator, and interpreter in reading multimodal English-medium texts. Interviews, observations, and think-aloud protocols were used to collect data. Two L2 students volunteered to take part in this multimodal text-based reading project. Findings showed that the students experienced different reading activities resulting from the absence and presence of guided literacy instruction. The students’ experiences differed in the ways the students maximized the use of webpage text features, navigated texts across hyperlinks, and interpreted multiple modes of texts during a meaning making process. The empirical implication of this study is that future research is needed to investigate factors influencing the implementation of guided literacy instruction in reading multimodal English-medium texts. Pedagogically, multimodal text can be a meaningful learning resource that students can use to learn a range of knowledge and language resources beyond the classroom zone.
The Psychological Content of Relationship between Sense and Meaning in Cultural-Historical Approach
Authors: Kravtsova E.E. , Kravtsov G.G.
Published: October 2018

The paper considers L.S. Vygotsky’s cultural-historical theory and its interpretation in modern psychology. It shows that psychological content of many concepts introduced by L.S. Vygotsky differs greatly from that of the ones used in theory and practice of modern psychological science. The authors state that L.S. Vygotsky’s main idea which shapes the specifics of cultural-historical psychology is the idea of sense primacy in relation to meaning. The analysis of subject content of the concept of «cultural development» allows us to affirm that L.S. Vygotsky understood the essence of learning process somewhat differently from what is now accepted. Learning in cultural-historical psychology promotes the development of will and self-regulation. Meanwhile, learning is seen not as a transformation of the external into the internal (process of interiorization), but as the ability to realize oneself in the outer world. At the same time, an important role in mental development and learning is played by another mental function, imagination.
Teacher-Student Interaction in Situations of Spontaneous Learning Independence in Primary Schoolchildren in Art Lessons within the System of Developmental Instruction
Authors: Poluyanov Y.A.
Published: October 2018

The paper describes outcomes of a pilot study on the features of interaction between a teacher and a child in art lessons within the system of developmental instruction. Two types of learning independence are reviewed: independence of performance — that is, when the child independently performs something familiar, repeating what the teacher has just explained or done; and independence of initiative — that is, when the child independently applies the general means of artistic activity while carrying out learning and creative tasks. We suppose that the second type of learning independence can be realized to the full extent in the process and outcomes of creative tasks, when the children design and implement their own, exclusive ideas in their drawings, sculptures and other handmade artifacts. Basing on our observations, it was revealed that the independence of initiative develops only if the teacher and the students actively interact with each other, when the teacher’s questions and actions stimulate the children to look out for different assessments (of their actions and outcomes) and to search not for one, but for many different ways of solving learning and creative tasks. Similarly, if the teacher spontaneously avoids or even deliberately ignores such situations in which the students look out for different ways of implementing their ideas, then the children’s independence of initiative simply disappears. The paper concludes with some suggestions concerning the relevant research tasks and techniques.
The Problem of Plot Construction in Primary Schoolchildren’s Drawings (A Commentary to the Paper by Yu.A. Poluyanov)
Authors: Guruzhapov V.A.
Published: October 2018

In this paper I present some commentaries to the paper by Yu.A. Poluyanov that was written in 2007 and is published in the current issue. The importance of his work is evident in the context of the actual tasks of raising the quality of psychological and pedagogical training of teachers in the present-day stage of development of the general education system. In the focus of the paper is the problem of spontaneous independence of initiative in primary schoolchildren at a particular stage when a teacher works with the children on the concepts of their drawings. Several examples are given to illustrate how the teacher can support the children in constructing plots for their drawings through discussions and individual work.
American Indian and Alaska Native Data in Federal Data Collections

Published: October 2018

American Indian and Alaska Native (AI/AN) tribes need access to quality data and information to make informed decisions concerning their communities, economic development, land and resource management, and other sovereign governance decisions. Federal agencies also need access to quality data to ensure that they are delivering effective services to AI/AN tribes to meet tribal needs and deliver on federal responsibilities. However, various statistical and collection issues often negatively affect the quality and availability of federally collected AI/AN data. As a preliminary step to identifying gaps and improving the quality and accuracy of AI/AN data in federal datasets, this article provides an inventory and preliminary analysis of current AI/AN in federal data collections. This inventory identifies 448 unique data collections from twenty-one federal agencies. These datasets were identified in 2016. One hundred and ninety-four (43.3%) of these datasets are publicly available, and seventy-nine of the publicly available datasets include data at the tribal or reservation level. An analysis of tribal/reservation level datasets by agency show that there are data gaps at the reservation/tribal level on businesses, the financial sector, tribal governments, labor markets, and education.
Netarsudil: a novel intra-ocular pressure lowering agent
Authors: Ghanghas Ravi R. , Mohan Prafull , Sharma Vikrant , Sharma Ashok K.
Published: October 2018

Optic disc health is an important indicator of visual functions. The first line of management to prevent/halt the damage to optic disc is to control responsible pathological condition, if identified. In absence of identifiable cause, the most validated approach is lowering of intra-ocular pressure (IOP). Individually, as well as combinations of currently available drugs are not fully effective in all patients of glaucoma in achieving desired IOP control. Hence, there is a need of newer alternatives which address this unmet need. Recently, a newer IOP lowering agent with a novel mechanism of action, netarsudil, has been approved by United States Food and Drug Administration (US-FDA) in December 2017. Netarsudil acts by inhibiting Rho-associated protein kinase resulting in lowering of overall tone of the contractible cells in trabecular meshwork thereby improving drainage of aqueous humor outflow and lowering of IOP. Though in its early days, this drug gives an armamentarium to ophthalmologists and physicians to control IOP in patients of open-angle glaucoma and ocular hypertension.
RUPTURAS E CONTINUIDADES DAS POLÍTICAS PÚBLICAS PARA A EDUCAÇÃO PROFISSIONAL NO BRASIL ENTRE 2003 E 2015
Authors: Maduro Silva Denise
Published: October 2018

No Brasil entre 2003 e 2015 tem-se um contexto de aposta, pelo governo federal, na educação profissional como motor do desenvolvimento social e econômico. Este trabalho visa apresentar e discutir as principais iniciativas em políticas públicas para a educação profissional no referido período, com especial atenção para o nível médio técnico. Em base à revisão documental e bibliográfica, são analisadas as lutas ideológicas e políticas na formulação e implementação das iniciativas educacionais, explicitando-se a ação dos grupos de poder na disputa pela direção do Estado. Conclui-se ressaltando as rupturas e continuidades históricas encontradas no tratamento dado à educação profissional de ensino médio técnico no período em análise. O novo modelo de educação profissional implantado no governo federal após as eleições de 2003, pauta-se na verticalidade da oferta de educação profissional e tecnológica, na articulação com o ensino regular, no aumento da escolaridade do trabalhador, na interação com o mundo do trabalho, e no apoio à escola pública. No entanto, esses ideais destacados dos discursos oficiais do governo, encontram embates ideológicos, políticos e estruturais para sua implementação, que condicionam os resultados alcançados. Desta forma, as políticas públicas do governo federal para a educação profissional analisadas para o período refletem e atualizam as disputas por poder presentes historicamente nas sociedades capitalistas e no Estado brasileiro.
GESTÃO ESCOLAR DEMOCRÁTICA: UM OLHAR SOBRE AS ESCOLAS DO CAMPO DO MUNICÍPIO DE ITABUNA – BA
Authors: Dos Santos Valéria Prazeres , Dos Santos Arlete Ramos
Published: October 2018

O presente artigo visa fazer uma discussão tomando como ponto de apoio uma pesquisa quali-quantitativa que teve como objetivo investigar como se dá a Gestão Democrática nas escolas do Campo do Município de Itabuna – BA, como uma ferramenta de transformação social no contexto do sistema capitalista. Os instrumentos para coleta de dados foram revisão bibliográfica e aplicação de questionários, e o referencial teórico traz como suporte o materialismo histórico dialético. Legalmente, fundamentamos nos documentos oficiais nacionais, Constituição federal (1988), Lei de Diretrizes e Bases (1996) e as Diretrizes Operacionais para a Educação Básica das Escolas do Campo (2002), no intuito de melhor entender como se efetiva a gestão escolar democrática no contexto campesino. No debate da democracia sob o viés socialista foram utilizados alguns autores, a exemplo de Coutinho (1979), Hora (2007) e Wood (2003), além de outros. Os resultados da pesquisa mostram que apesar de muitas vezes afirmar-se que existe gestão democrática nas escolas do campo, as práticas não são verdadeiramente democráticas, uma vez que não envolve todos os sujeitos da comunidade escolar
De migrante a industriário: a reconstrução da vida na cidade de Manaus
Authors: Andrade Aldair Oliveira de
Published: October 2018

Este trabalho abordou do processo de reconstrução da vida de migrantes amazonenses na cidade de Manaus, que aportaram à capital a partir da década de 1960, nela desempenharam ou desempenham atividades no Polo Industrial de Manaus (PIM). O trabalho teve como intenção, a partir das narrativas dos migrantes, situar a construção do projeto migratório, os dilemas que envolveram o ato de migrar, a chegada à capital, a inserção no mundo do trabalho, a construção de novos espaços de sociabilidade, dentre outras questões, as quais nos ajudaram a identificar se o projeto construído na origem se consolidou no destino. Nos debruçamos sobre uma pesquisa bibliográfica, matérias jornalísticas e os relatórios oficiais do poder público, e acentuadamente da pesquisa de campo. A coleta de campo foi realizada a partir de entrevistas semiestruturadas com trabalhadores migrantes que atuam ou atuaram no PIM, com base nos critérios previamente estabelecidos, no intuito de conhecer como era a vida na origem, o que determinou a decisão de migrar, como se deu o deslocamento, como foi o estabelecimento em Manaus, quais as principais dificuldades enfrentadas, como se tornaram industriários, como é a vida no espaço fabril e como eles construíram novas relações sociais. De modo geral podemos asseverar que o estudo evidenciou que nem todos construíram seus próprios projetos migratórios na origem, visto que eram crianças e adolescentes, que tiveram a decisão tomada por pais ou responsáveis. A presença de familiares e conhecidos no destino (capital) foi um elemento fundamental para subsidiar a decisão de migrar. Os migrantes se tornaram industriários somente após a chegada à Manaus, por isso, nesta pesquisa adotou-se o termo migrantes industriários. Ao comparar a vida na origem e no destino, inferimos que houve melhoria de vida, sendo os principais objetivos do projeto migratório, estudo, trabalho e moradia, foram alcançados por maioria significativa dos migrantes, muito embora os relatos não deixem de revelar a dureza da vida de um industriário, que tem a maior parte de seu tempo consumida pelo trabalho.

Published: October 2018

Este trabalho estuda métodos de modulação PWM para conversores de tensão trifásicos de quatrobraços. O objetivo é estabelecer uma análise comparativa entre esses métodos e mostrar as vantagens de usar esse tipo de conversor. Há dois métodos principais de implementação de moduladores PWM para os conversores de quatro-braços. O primeiro usa um arranjo de vetores de tensão em uma interpretação geométrica no espaço vetorial tridimensional. O outro método é baseado na escolha a priori de um padrão otimizado de chaveamento e usando do conceito da tensão de off-set. Um interpretação própria é desenvolvida baseada nestes dois métodos considerados. O interesse é conciliar as vantagens de ambas as técnicas. O modulador proposto é implementado em um processador digital de sinais (DSP - Digital Signal Processor) o TMS320F2812 da Texas Instruments. Resultados de simulações e experimentais são apresentados para validar o algoritmo de PWM desenvolvido para o conversores de tensão trifásicos de quatro-braços.

Este artigo trata do estudo de um sistema eólico de pequeno porte utilizado para carregamento de baterias. Uma topologia que visa o aproveitamento da energia gerada em baixas velocidades é proposta. As características da turbina eólica e do gerador utilizado são discutidas, dando uma completa visão da modelagem do sistema. Uma simulação do sistema (MATLABSIMULINK) também é feita e os resultados simulados são discutidos e comparados com os experimentais, obtidos a partir de um protótipo de 1kW, de modo a validar a proposta do aproveitamento na energia gerada em baixas velocidades (130 A 270 rpm).
An Efficient Maximum-power-point-tracking Controller For Grid-connected Photovoltaic Energy Conversion System
Authors: Molina Marcelo G. , Pontoriero Domingo H. , Mercado Pedro Enrique
Published: October 2018

This paper investigates the effectiveness of the “Perturbation and Observation” (P&O) method and “Incremental Conductance” (IncCond) method through simulations carried out by using SimPowerSystems of MATLAB/Simulink®. Both the steady-state and transient characteristics of each control algorithm are fully analyzed and compared by using a proposed performance index. Finally, a new MPPT control algorithm based on an enhanced incremental conductance method is proposed in order to improve the efficiency of the PV power generation system at different climatic and load conditions. An adaptive duty cycle perturbation step size is made dependent on the sensitivity of the PV array power to the previous perturbation in order to obtain a fast dynamic response and accurate tracking of the MPP. Digital simulations and experimental results demonstrate the superior performance of the proposed technique.

Este trabalho apresenta um inversor com potência nominal de 1kW, desenvolvido para aplicação em fontes de energia renovável. O equipamento pode operar em dois modos: autônomo ou conectado à rede elétrica com controle do fluxo de potência. O conversor é composto de três estágios: inversor de alta freqüência, retificador em ponte e inversor SPWM de baixa freqüência. O sistema proposto foi implementado com isolação galvânica e opera com tensão de entrada contínua entre 30V e 60V, obtendo-se tensão eficaz de saída de 110V ou 240V com freqüência de 50Hz ou 60Hz. THD, eficiência e regulação são parâmetros de desempenho que serão avaliados. Resultados experimentais para cada condição de operação serão apresentados neste desenvolvimento. Características como custo, volume e peso também são descritas.

Published: October 2018

This paper presents a design methodology for the digital controllers of a three-phase UPS (Uninterruptible Power Supply). Upon a state-feedback control topology, a systematic method for pole placement and determination of controller gains was developed. In order to attest the efficiency of the adopted control scheme, experimental tests were carried out on a 4kVA three-phase on-line UPS, resulting in unity power factor operation of the controlled rectifier and low harmonic distortion of inverter output voltage, even under heavy non-linear loads.
Máquina De Indução Sem Mancais: Modelo E Acionamento
Authors: Ferreira Jossana M. S. , Salazar Andrés Ortiz
Published: October 2018

Este trabalho apresenta uma proposta de modelo para a máquina de indução trifásica sem mancais com bobinado dividido bem como a estrutura montada para o seu acionamento. A máquina estudada é uma adaptação de uma máquina de indução convencional, o que foi possível dividindo-se os enrolamentos do estator e tornando acessíveis todos os seus terminais. Essa técnica dispensa o acréscimo de enrolamentos ao estator para a realização do controle de posição radial, o que resulta em uma máquina sem mancais mais compacta. Resultados experimentais são realizados para validar esta modelagem.

Published: October 2018

This study aims to
examine the contribution of the perceived support and sense of class belonging
to pre-service teachers’ career motivation. A total of 670 pre-service teachers
majoring in various teaching areas including science, social studies, Turkish
and mathematics at a state university in Aegean Region participated in the
study. Self-report questionnaires including the FIT-Choice Scale, the
Psychological Sense of School Membership Scale, and the Support Scale were used
as data collection tools. Hierarchical multiple regression analysis was
utilized to determine the extent to what level of the variance explained in the
motivational factors and the perception about teaching by support and sense of
class belonging. Results of analysis showed statistically significant relations
between sense of class belonging and the FIT-Choice scale. Additional to this,
it was found to be statistically significant relations between the support
types and the FIT-Choice scale, while support from instructors was the
strongest predictor of motivation. Future directions and implications were
discussed.
Inmates with Harmful Substance Use Increase both Exercise and Nicotine Use under Incarceration

Published: October 2018

Background: Exercise is increasingly understood as an important resource for people with harmful substance use, including those in prison. Little is known about how inmates adopt various health behaviors during incarceration, without interventions. Methods: This study analyzed self-reports from 1468 inmates in Norwegian prisons, compared them according to harmful substance use pre-incarceration, and explored changes in exercise and nicotine use during incarceration. Results were presented in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Results: Inmates with harmful substance use reported higher rates of smoking, smokeless tobacco, and physical inactivity pre-incarceration than inmates without harmful use. However, inmates with harmful use also exhibited more behavioral changes: they adopted exercise, ceased smoking, and adopted smokeless tobacco at higher rates during incarceration than the non-harmful group.  Conclusions: Exercise is being taken up by a significant proportion of inmates, and may in particular be a replacement behavior for substance use. However, unhealthy behaviors are also begun or maintained. If prisons were used as an arena to facilitate healthy behaviors, the public health benefits to a marginalized group such as substance-using inmates could be substantial.
The Lightness of the Sexual Being: A Short Reflection on Hans Christian Andersen’s “The Little Mermaid”
Authors: Lee Seungyeon
Published: October 2018

Hans Christian Andersen’s tale, “The Little Mermaid,” have been adored by children and their parents for decades. The tale shows an astonishing quality to Andersen’s early fairy tales, which allows the reader to sense his keenness on the meaning of human sexuality on this genre. The author used the short narrative form so that he became more conservative, catuious, and concise for delivering his ideological compromise between his religiosity and understanding of human nature. “The Little Mermaid” is one of the tales that draws the reader on “universal preoccupations” of femininity, self-concept, and self-actualization. Andersen’s intentions and authenticity of this tale should not be overlooked.
