Teaching Photonics
Authors: Rutkowska Katarzyna Agnieszka , Karpierz Mirosław
Published: October 2017

There is a need to teach modern photonics as a tool for technology of the 21st century. Apart from the studies in Applied Physics, Faculty of Physics at the Warsaw University of Technology (WUT) offers a program in English which leads to the M.Sc. degree in Photonics. The two-year graduate program in the area of Photonics provides students a unique opportunity to become familiar with the applications of light in fields that range from fundamental research to technological applications. The aim of this Master?s Program is to form engineers and scientists with solid basic knowledge in the field of photonics and with the skills to apply this knowledge to the design, realization and the management of photonic systems for a broad range of application domains.
Galvanic Series in Seawater as a Function of Temperature, Oxygen Content, and Chlorination
Authors: Thierry Dominique , Leballeur Charles , Larché Nicolas
Published: October 2017

The open-circuit potential is one of the main driving forces of galvanic corrosion when two dissimilar metals are in electrical continuity in an electrolyte. From the existing literature, the galvanic series which provides averaged potential of metallic materials in seawater is generally restricted to ambient/standard conditions or to a limited number of alloys. However, advanced materials have been developed in the last decade and the corrosion potential of any alloy immersed in seawater may be strongly affected by environmental factors. There is a lack of information on these purposes (e.g., effect of dissolved oxygen content, temperatures, chlorination at different levels, or recently developed alloys, etc.). In this work, the open-circuit potential of different stainless steel grades, as well as nickel-based and copper-based alloys, has been systematically measured in seawater under different experimental conditions. In particular, the effect of temperature (from 30°C to 70°C), oxygen content (from 10 ppb to saturation), and chlorination level (from 0 ppm to 0.5 ppm) have been studied. The work can also be used for material selection in terms of risk of bi-metallic corrosion when coupling two materials under these conditions.
La casa Malaparte: espacio fílmico y arquitectura de autor
Authors: Sánchez-Noriega José L.
Published: October 2017

Hay una rica y variada interrelación entre la arquitectura y el cine. Algunas casas y edificios singulares adquieren personalidad y casi la condición de personajes en determinadas películas, tanto en el cine de género -la “casa encantada” en el cine de terror- como en filmes de autor. La casa Malaparte de Capri responde a una arquitectura muy personal y se ubica en un espacio singular que ha servido, en distintos rodajes, para un espacio fílmico que trasciende el mero marco o contenedor de historias; forma parte de una tipología de casa que desafía la gravedad. La adaptación de la novela del propio Curzio Malaparte emplea esta casa como escenario de algunas secuencias, más por su pertenencia al escritor que por el espacio en sí mismo o su lugar en el relato. A partir de una novela, Godard crea en El desprecio un texto rico en capas y evocaciones que remite a la mitología de Ulises al tiempo que reflexiona sobre la imposibilidad del amor y la supervivencia de la pareja.
Estudio sobre los planteamientos teóricos y metodológicos de los Estudios Visuales
Authors: Contreras Fernando
Published: October 2017

Este artículo muestra los principales planteamientos teóricos y explica la función de metodologías interdisciplinares en los Estudios Visuales. Para ello realizamos un recorrido por los conceptos centrales del análisis del arte visual (el esencialismo visual, los objetos visuales, la cultura visual, el pensamiento visual, los regímenes escópicos), así como tratamos relevantes debates críticos sobre las carencias de la historia del arte, la teoría del arte o la estética en el análisis de las nuevas imágenes mediáticas. El estudio demuestra que la evolución teórica del análisis visual sobrepasa la interpretación histórica del arte y se extiende en el conocimiento de la construcción social de la experiencia visual, o dicho de otro modo, en la construcción visual de lo social.
Residencias artísticas virtuales: presentación, compilación y análisis desde la experiencia del anfitrión
Authors: López-Martín Elena , Morgado-Aguirre Borja
Published: October 2017

Los programas de residencias artísticas virtuales son un fenómeno generalmente desconocido tanto fuera como dentro de los circuitos artísticos hegemónicos en relación a sus homólogos no digitales. Sin embargo, estas innovadoras iniciativas ofrecen numerosas ventajas y oportunidades a los artistas interesados en generar nuevas dimensiones para la expresión artística en el espacio de Internet. Tras la detección de una notable escasez de estudios profesionales sobre las residencias artísticas virtuales, la presente investigación tiene como objetivo darlas a conocer mediante la generación de una base teórica fundamental, aumentar la literatura crítica en torno a este fenómeno y fomentar, a través del conocimiento, la participación, difusión y creación de dichos programas. La metodología empleada parte de la revisión de la literatura crítica existente acerca de las residencias artísticas tanto físicas como virtuales y combina la recopilación y análisis de datos objetivos con el estudio de la interpretación subjetiva procedente de las organizaciones, denominadas “anfitriones”, implicadas en la creación y desarrollo de estas iniciativas. Finalmente, del análisis conjunto de estos datos cuantitativos y cualitativos que pretenden responder a qué es una residencia artística virtual y qué implica, resulta oportuno proponer una definición práctica y específica de dichas residencias que incluya las distintas aportaciones que han ido surgiendo y se han ido abordando a lo largo de la investigación.
El maniquí y la pintura en la primera mitad del siglo XX: realidad "versus" artificio
Authors: García-Calvente Pablo
Published: October 2017

Es significativo que los estudios que han proliferado durante las últimas décadas sobre la importancia del aprendizaje de la anatomía en la formación artística se hayan centrado, casi exclusivamente, en la problemática en torno a la trascendencia del papel de los modelos vivos, descuidando, en cambio, la relevancia del maniquí en esta tarea, a pesar de que, durante más de cinco siglos, este ha desempeñado, entre el rechazo absoluto y la reivindicación entusiasta, la función de sustituto de aquel en el proceso creativo. En este trabajo se abordará la controvertida cuestión que, a través de la representación del maniquí, se manifiesta entre realidad y artificio en la pintura europea de la primera mitad del siglo XX: desde el gesto provocador que entraña la confrontación deliberada en el lienzo del maniquí con el modelo vivo hasta el rol evocador e incluso subversivo que este artilugio, versátil e inquietante, desempeñará en la producción pictórica de las vanguardias.

Published: October 2017

El presente artículo aborda la relación entre diseño y la cultura. Se enfoca principalmente en descubrir las mecánicas a través de las cuales el diseño permanece o se modifica. Para el efecto, explora el producto del diseño desde la mirada semiótica y el enfoque evolucionista y trata de aclarar las formas en las que el diseño es portador de significados y, por tanto, su rol en el mantenimiento y la revitalización de la identidad cultural. Desde una mirada inter y transdisciplinaria, se plantea una reflexión y propuesta teórica que luego es validada a través de un análisis de casos guiado por la metodología del análisis de contenidos y el procesamiento multivariado de datos, para finalmente decantar en una propuesta que trata de dar una mirada al tránsito acelerado de los objetos de consumo en la sociedad contemporánea.
The Friar, the Summoner, and Their Techniques of Erasure
Authors: Saltzman Benjamin A.
Published: October 2017

In the Friar's Tale, the summoner extorts his victims with the promise of striking their names from his “feyned mandement.” Then, in the Summoner's Tale, the friar's companion planes away the names of their patrons from his wax tablets. In these two parallel acts, we get a glimpse into a deep-seated cultural anxiety over the opportunities and dangers posed by various forms of textual and documentary erasure. This article explores the materiality and literary significance of such erasures, which ultimately invite us to revise our view of these two antagonistic tales and read them not merely as a simple expression of quiting, but instead as an instance of mutual cancellation in which the erasure of a name simultaneously inscribes a person into the narrative.
Secretary a in Ellesmere's Latin Quotations
Authors: Farrell Thomas J.
Published: October 2017

The occasional appearance of the secretary graph for minuscule a in the Latin Quotations provided in the Ellesmere manuscript as annotations to the Canterbury Tales is not (as previously characterized) random. More than 99% of its appearances occur in passages where El shared an exemplar with Gg. The likelihood that those annotations were copied into El from its exemplars is therefore very high, and the likelihood that such annotations derive from a Chaucerian intent is significantly increased. Those facts have important repercussions for our understanding not only of the origins and transmission of the annotations but of the textual nature of the Canterbury Tales.
The Exchange of Hearts in the English Poems of Charles d'Orléans
Authors: Burrow John
Published: October 2017

There are so many references to hearts in the English Book of Love by Charles d'Orléans that readers may fail to recognize the crucial significance of an exchange of hearts. It is for such a consensual relationship that Charles pleads in both his love affairs, successfully in the first, but unsuccessfully (notwithstanding Ballade 117) in the second. This article considers the various arguments that the lover derives from the exchange-of-hearts trope in support of his pleas to both women—witty arguments, but directed to a most serious end.
A problemática da produção da subjetividade em aula: reflexões acerca da docência universitária na área das Ciências Humanas
Authors: Santos Filho Francisco Carlos dos , De Carli Fabíola Giacomini , Caimi Flávia Eloisa
Published: October 2017

O estudo aborda a problemática da docência universitária na área das Ciências Humanas, partindo de uma experiência educativa desenvolvida na disciplina intitulada Trabalho e Subjetividade, com alunos de um curso de especialização lato sensu na área de Gestão de Recursos Humanos, em uma instituição de ensino superior situada no interior do estado do Rio Grande do Sul. A reflexão é desenvolvida na interface da psicanálise e da educação, reconhecendo que a construção do conhecimento depende, em larga medida, da produção de efeitos de subjetivação nos envolvidos no processo educativo, no interior de uma relação de alteridade entre professor e aluno, que pode ser possível construir durante o encontro áulico.
CRESCIMENTO INICIAL DE QUATRO ESPÉCIES FLORESTAIS NATIVAS EM ÁREA DEGRADADA COM DIFERENTES NÍVEIS DE CALAGEM E DE ADUBAÇÃO
Authors: Scheer Maurício Bergamini , Carneiro Charles , Bressan Otávio Augusto , Dos Santos Kaline Gomes
Published: October 2017

O presente trabalho teve o objetivo de avaliar o crescimento inicial de mudas de Schinus terebinthifolius, Gymnanthes klotzschiana, Luehea divaricata e Lafoensia pacari em área degradada (usada como área empréstimo), submetidas a três níveis de fertilizante NPK 5-20-10 (0, 300 e 500 g por cova) e dois níveis de calagem (calcário dolomítico com 75% de PRNT) (250 e 500 g por cova). As medições das alturas e diâmetros à altura da base foram realizadas após dois anos do plantio no campo. A dose de 250 g de calcário por cova possibilitou, na maioria dos casos, o melhor desenvolvimento das espécies utilizadas no experimento. A dose de 500 g de calcário, em algumas situações, afetou o crescimento das plantas, provavelmente em função do aumento excessivo de pH e consequente diminuição da disponibilidade de micronutrientes e/ou pelo desbalanço nutricional ocasionado. A adubação com fertilizante NPK influenciou de forma distinta no crescimento de cada espécie, apresentando respostas diferenciadas com relação às dosagens utilizadas, de acordo com as necessidades nutricionais da espécie. A espécie que apresentou melhor crescimento sob as condições do experimento, foi Schinus terebinthifolius, com alturas e diâmetro estatisticamente superiores as demais.

Authors: Caixeta Ana Carolina , Marchesan Raquel , Bloise Pieroni Gustavo , Coelho Almeida Vanessa , Silva Vieira Renato , Bueno de Moraes Cristiano
Published: October 2017

O objetivo deste estudo foi avaliar a qualidade de toras e madeira de Araucaria angustifolia para o processo de laminação destinado a produção de painéis laminados. As árvores foram provenientes de um plantio seminal de 39 anos de idade, localizado no município de Palma Sola, SC. A qualidade das toras para laminação foi analisada quanto a conicidade e o achatamento de acordo com IBDF (1984). O colapso da madeira foi determinado seguindo a metodologia adotada por Welling (1994) e a densidade básica e retração obedeceram à norma NBR 7190 (ABNT, 1997) e NBR 11941 (ABNT, 2003) respectivamente. Os resultados encontrados para as características de forma do fuste apresentam-se com características favoráveis a produção de lâminas homogêneas, de acordo com a classificação do IBDF (1984). A densidade básica na direção radial apresentou aumento significativo da medula à casca, enquanto no sentido longitudinal, foi decrescente da base ao topo, com tendência de estabilização dos valores a partir da posição referente a 75% da altura comercial. O colapso da madeira foi caracterizado como de grau médio e a variação dimensional classificada como de alta estabilidade, podendo ser utilizadas para a produção de painéis laminados.

Published: October 2017

This study aimed to manufacture oriented wood-cement boards using five Eucalyptus species and mixture between then, to compare the effect of the particles orientation, and to evaluate the physical and mechanical properties according to competent standards. The species studied were: Eucalyptus benthamii, Eucalyptus dunni, Eucalyptus grandis, Eucalyptus saligna, Eucalyptus urograndis the mixture between them and the Pinus taeda as control.  The bonding agent employed was commercial grade Portland cement types CP II-Z-32R. The panels had dimensions of 48 x 48 x 1.2 cm and nominal specific mass of 1.2 g/cm³. The cement/wood/water mass ratio used was 2.5:1:1 and 2% of CaCl2 by weight of cement was used as an additive. The orientation of strands did not influence the dimensional stability properties. All boards had very low IB strength, being that, none treatments reached the requirements to internal bond of competent standards. The MOR and MOE results indicated that species mixture can be obtained boards with properties similar to pure species. In general, the boards showed low mechanical strength what can be attributed to particles geometry and wood-cement ratio. The wood of Eucalyptus species presents potential for use in cement-wood panels.

Published: October 2017

A Hevea brasiliensis (seringueira) é uma espécie nativa da Amazônia e apresenta elevada importância econômica no Brasil, por ser amplamente utilizada na obtenção de latéx para produção de borracha. Os plantios comerciais da Hevea brasiliensis estão localizados principalmente no interior do estado de São Paulo e se encontram ainda na fase de extração de látex, tendo a necessidade de estudos tecnológicos para a utilização da sua madeira ao final do seu ciclo. Na busca por alternativas para uso industrial da sua madeira, esta pesquisa teve como objetivo avaliar o seu potencial para produção de painéis cimento-madeira. Para a produção de painéis experimentais foram empregadas partículas de madeira tratadas por imersão em água fria por 24h, água quente por 6h e hidróxido de sódio (NaOH) por 2 horas; e Cloreto de cálcio (CaCl2) e Silicato de Sódio (Na2SiO3) como aceleradores de endurecimento do cimento. Os painéis foram produzidos com densidade nominal de 1,10 g/cm³, relação madeira cimento de 1:2,75, fator água cimento de 0,4 e 3% de aceleradores de cura. Os ensaios físicos e mecânicos dos painéis indicaram melhores resultados para os painéis produzidos com partículas tratadas em água quente por 6 horas e uso do cloreto de cálcio como acelerador de endurecimento. Os resultados permitem concluir que a madeira de Hevea brasiliensis (RRIM 600) apresenta potencial para a produção de painéis cimento-madeira.

Authors: Arruda Enoque Leda de , Andrade Azarias Machado de , Dias Júnior Ananias Francisco
Published: October 2017

Este estudo teve por objetivo analisar as variáveis da produção do carvão vegetal das madeiras de Acacia mangium, Pseudosamanea guachapelle e Eucalyptus grandis e analisar a capacidade de adsorção de pigmentos pelos carvões produzidos e ativados com vapor d’água superaquecido. Para isso, as amostras das madeiras foram carbonizadas sob as temperaturas de 400, 500 e 600 °C numa velocidade de aquecimento de 1,67 °C min-1 e tempo total de carbonização de 4, 5 e 6 horas, respectivamente. Após a carbonização, determinaram-se os rendimentos gravimétricos em carvão, líquido pirolenhoso, gases não condensáveis e realizou-se a análise imediata dos carvões. Os carvões foram ativados sob a ação de vapor d’água superaquecido e testados em relação à adsorção de pigmentos coloridos dissolvidos em água. Para as três espécies analisadas, as menores temperaturas de carbonização proporcionaram os maiores rendimentos em carvão vegetal. As maiores temperaturas de carbonização resultaram nos menores teores de materiais voláteis e maiores teores de carbono fixo nos carvões. A ativação com vapor d’água superaquecido influenciou positivamente a adsorção de pigmentos do carvão de P. guachapelle produzido a 400 °C e dos carvões de A. mangium e E. grandis produzidos a 500 °C. A madeira de P. guachapelle carbonizada à 400 °C se destacou em relação às duas outras espécies florestais analisadas.
Práticas (não) hegemônicas em saúde: uma análise a partir dos Estudos Culturais
Authors: Mallmann Camila Luzia , Rocha Cristianne Maria Famer
Published: October 2017

Temos como tema as práticas biomédicas (hegemônicas) e Práticas Integrativas e Complementares em Saúde (não hegemônicas), que estão presentes no contexto do Sistema Único de Saúde brasileiro. O objetivo é refletir sobre tensionamentos entre as práticas biomédicas e esse conjunto de práticas não hegemônicas que emergem culturalmente e no campo da saúde, a partir das lentes analíticas dos Estudos Culturais. Como percurso metodológico, realizou-se uma breve apresentação do tema e, posteriormente, uma conversa teórica com autores pós-estruturalistas que abordam as temáticas em questão a partir de aspectos da cultura, com o uso da pesquisa exploratória qualitativa. Esse estudo fortaleceu a importância de pensarmos a produção de saúde como algo criado, construído em cada tempo/ lugar/contexto, bem como da importância de se pensar que, mesmo que modelos teóricos busquem delimitações, o que encontramos enquanto cuidados de saúde são práticas borradas, ou seja, o consumo cultural da saúde é amorfo e seus significados são construídos por quem os consomem.
A utilização da pesquisa-ação na administração: engajamento político ou intervenção prática?
Authors: Zanella Cleunice
Published: October 2017

A pesquisa-ação quando aplicada aos estudos organizacionais pode ter dupla orientação: engajamento político ou intervenção prática. Este estudo objetiva analisar o enfoque de aplicação da pesquisa-ação nas pesquisas em Administração a partir das bases de dados e periódicos indexados a Capes. Foram selecionados 16 artigos nacionais e 7 internacionais que indicaram o uso desta abordagem metodológica no desenvolvimento das suas pesquisas. Os dados foram coletados a partir de uma pesquisa bibliográfica, com caráter descritivo e abordagem qualitativa. Os resultados mostram que, apesar de afirmarem ter usado a pesquisa-ação em seus estudos, em parte dos artigos analisados não é possível verificar a aplicação da pesquisa-ação. Há indícios ainda de que, de maneira geral, os autores não distinguem adequadamente suas intenções com o uso da pesquisa-ação e que há predominância do seu uso na busca por melhorias de processos organizacionais, a partir da busca por solução de problemas evidenciados pelas organizações.
Características de las madres primerizas y de los padres primerizos en la España del siglo XXI
Authors: Miret-Gamundi Pau , Vidal-Coso Elena
Published: October 2017

Este trabajo analiza la primofecundidad femenina y masculina en España entre 1999 y 2015. A través de la Encuesta de Población Activa en su versión panel, la probabilidad de tener un primer hijo se controla por edad y periodo de observación, y las variables independientes son el lugar de nacimiento, el nivel de instrucción y la relación con la actividad. Los resultados confirman el aplazamiento de la primera fecundidad entre los hombres y mujeres con mayor nivel educativo. La pervivencia de un patrón de género explicaría la mayor probabilidad de primera maternidad de las inactivas, mientras que el trabajo es indispensable para ser padre primerizo. No obstante, el desempleo y la temporalidad afectan negativamente a ambos sexos. La aportación de la población inmigrada queda confirmada especialmente por su calendario temprano.
Las preferencias de gasto público de los españoles ¿interés propio o valores?
Authors: Cicuéndez Santamaría Ruth
Published: October 2017

En este artículo se analizan algunos de los factores que condicionan las preferencias de gasto público de los ciudadanos en España, centrándose en el papel que juegan las motivaciones económicas de los individuos, su ideología y sus valores. Para abordar estas cuestiones, se han aplicado dos teorías: la del interés propio y la de las predisposiciones simbólicas. El análisis empírico demuestra que tanto las características sociodemográficas y económicas como la ideología y las creencias de los ciudadanos influyen en la articulación de las demandas específicas de gasto público. Además, se identifica cuáles son los mejores predictores de las preferencias en cada programa de gasto, concluyendo que el impacto del interés propio y de las predisposiciones simbólicas varía significativamente en función de la naturaleza de las diferentes políticas públicas.
¿Influye la pobreza en la juventud en la pobreza en la etapa adulta? Un análisis para España
Authors: Cueto Begoña , Rodríguez: Vanesa , Suárez Patricia
Published: October 2017

La correlación de los logros económicos, sociales y educativos entre generaciones de la misma familia es una cuestión de gran interés para el análisis de la igualdad de oportunidades en la sociedad. Nuestro objetivo en este artículo es cuantificar la incidencia e intensidad de la transmisión intergeneracional de la pobreza en España. Con datos del módulo específico sobre transmisión intergeneracional de situaciones de dificultades económicas de la ECV 2011 se utiliza el propensity score matchingpara estudiar la relación entre las dificultades económicas de una generación y las de la siguiente. Los resultados muestran que haber tenido dificultades económicas durante la adolescencia aumenta la probabilidad de pobreza en la etapa adulta. Este impacto se ha reducido en las generaciones más jóvenes.
Interlaboratory Validation of a Stable Isotope Dilution and Liquid Chromatography Tandem Mass Spectrometry Method for the Determination of Aflatoxins in Milk, Milk-Based Infant Formula, and Feed
Authors: Zhang Kai , Liao Chia-Ding , Prakash Shristi , Conway Michael , Cheng Hwei-Fang
Published: October 2017

An interlaboratory study was conducted to evaluate stable isotope dilution and LC tandem MS (MS/MS) for the determination of aflatoxins B1, B2, G1, G2, and M1 (AFB1, AFB2, AFG1, AFG2, and AFM1) in milk, milk-based infant formula (formula), and feed. Samples were first fortified with five 13C uniformly labeled aflatoxins {[13C]–internal standard (IS)} corresponding to the five native aflatoxins, which were subsequently extracted with acetonitrile–water (50 + 50, v/v), followed by centrifugation, filtration, and LC-MS/MS analysis. In addition to certified milk powder and animal feed, the three participating laboratories also analyzed milk, formula, and feed fortified with the five aflatoxins at concentrations ranging from 0.5 to 50 ng/g. The majority of recoveries ranged from 80 to 120%, with RSDs < 20%. Method LOQs were determined by the three laboratories using the three sample matrixes in replicates (n = 8), and the determined LOQs of AFB1, AFB2, AFG1, AFG2, and AFM1 ranged from 0.1 to 0.91, 0.24 to 0.64, 0.28 to 1.52, 0.19 to 3.80, and 0.12 to 0.45 ng/g, respectively. For detected aflatoxins in the certified materials, all measured concentrations were within ±25% of the certified values. Using [13C]–IS eliminated the need for matrix-matched calibration standards for quantitation, simplified sample preparation, and achieved simultaneous identification and quantitation of the aflatoxins in a simple LC-MS/MS procedure.

A luta pela terra no Brasil: sinal da passagem de Deus
Authors: Vitório Jaldemir
Published: October 2017

O tema da posse e do usufruto da terra, no Brasil, tornou-se problema desde a chegada dos conquistadores portugueses, no início do séc. XVI. Arrancada das mãos dos habitantes primitivos do solo brasileiro, a propriedade fundiária tornou assunto da Coroa Portuguesa, que transformou sua nova colônia em reservatório de inesgotáveis recursos naturais. As lutas para superar a exploração dos colonizadores começou desde cedo, numa tentativa de dar à terra sua destinação social, para além da visão mercantilista europeia. O Movimento dos Trabalhadores Rurais Sem Terra (MST) inscreve-se numa larga epopeia de luta pela terra, numa guerra sem trégua contra o latifúndio, tendo no horizonte a utopia do acesso de todos à terra, de modo especial, quem dela depende para trabalhar, produzir e sobreviver, na contramão do agrobusiness e sua ação destruidora do solo e do recursos naturais. Uma leitura teológica da ação MST detecta, nas entrelinhas do movimento, os sinais da passagem de Deus, como na história do Povo de Israel, libertado da terra da escravidão e conduzido à terra da fraternidade. 
Effect of Heating Spacing on Deformation Distribution of Line Heating Process
Authors: Han Xiaoshuang , Zhou Bo , Tan Soon-Keat
Published: October 2017

Ship hull plate forming with line heating technique is an important process in the shipbuilding industry. An automatic line heating control system needs an accurate database of various processing parameters. In this study, a numerical model, calibrated and verified using experiment results, was used to study the deformation distribution of a plate corresponding to different heating line spacing. This paper presents the results based on a single-torch and multiple-torch process. The deformation distributions in the heating and nonheating regions were analyzed. The impacts of coupling effect among heating lines were deliberated.

1. Introduction

Line heating is an efficient plate forming process for many applications, such as ship hull forming, molding car body, and other curved objects. In the shipbuilding industry, this method is mainly used to create double-curved ship hull plates, especially for those plates near the bow and stern. Line heating is a complex nonlinear thermal process that involves thermodynamics, elastic-plastic mechanics, and metallurgy. Many researchers have conducted studies on the mechanism of line heating process to predict the final shape of the metal plate according to the heating conditions and mechanical properties of the plate (Moshaiov & Vorus 1987; Ueda et al. 1994a, 1994b, 1994c; Ji & Liu 2001); others performed numerical analysis with thermal elastic-plastic models to determine the parameters in line heating process (Jang et al. 1997; Yu et al. 1999,2001; Yu 2000; Wang et al. 2006). Many experimental works were carried out to verify the thermal elastic-plastic models (Moshaiov & Shin 1991; Liu et al. 2006; Zhou et al. 2014a). The effects of parallel and cross heating lines were discussed recently (Zhou et al. 2014b; Vega et al. 2015). Residual stress among the steel plate was studied to reveal the relationship of different heating conditions.

Different heat sources have been used in line heating process, and they include gas torch(Tomita et al. 2001; Jong & Jong 2003), laser beam (Kyrsanidi et al. 1999), welding arc (Kitamura et al. 1996), and high-frequency induction heating (Ogawa et al. 1994; Lee & Hwang 2014). In all heat sources, gas torch is most frequently used as it was and still is the cheapest and most readily available heating source in most shipyards.

Published: October 2017

The importance of increasing scholarly activity has been highlighted among residency programs currently accredited by the American Osteopathic Association (AOA) to ensure a smooth transition to the single accreditation system. The Scholar 7 program, a series of seven 2-hour sessions, was created to aid faculty and residents in the pursuit of scholarly work and to facilitate change in an entire community hospital system's environment by creating a self-replicating scholarly culture in a timely and cost-efficient manner. Skills were taught by means of preparation and submission of a research protocol to the institutional review board (IRB) along with grant proposals. The authors tracked scholarly work, IRB submissions, and grants awarded to participants during the 2015-2016 academic year. The results were compared in a post-hoc fashion with previous classes since 2007-2008 within the same hospitals system. The Scholar 7 program successfully aided faculty in achieving their required pursuit of scholarly work in 8 months. This program has the potential to help AOA-focused residency programs meet the scholarly requirements of the Accreditation Council for Graduate Medical Education.

Published: October 2017

Italian ryegrass (Lolium multiflorum) is an important cool-season, annual forage crop for the grassland rotation system in Southern China. The primary aim of breeding programs is always to seek to improve forage quality in the animal productivity system; however, it is time- and labor-consuming when analyzed excessive large number of samples. The main objectives of this study were to construct near-infrared reflectance spectroscopy (NIRS) models to predict the forage chemistry quality of Italian ryegrass including the concentrations of crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), and water soluble carbohydrate (WSC). The results showed that a broader range of CP, NDF, ADF and WSC contents (%DM) were obtained (4.45–30.60, 21.29–60.47, 11.66–36.17 and 3.95–51.52, respectively) from the samples selected for developing NIRS models. In addition, the critical wavelengths identified in this study to construct optimal NIRS models were located in 4,247–6,102 and 4,247–5,450 cm-1 for CP and NDF content, and both wavelengths 5,446–6,102 and 4,247–4,602 cm-1 could for ADF and WSC. Finally, the optimal models were developed based on the laboratory data and the spectral information by partial least squares (PLS) regression, with relatively high coefficients of determination (R2CV, CP = 0.99, NDF = 0.94, ADF = 0.92, WSC = 0.88), ratio of prediction to devitation (RPD, CP = 8.58, NDF = 4.25, ADF = 3.64, WSC = 3.10). The further statistics of prediction errors relative to laboratory (PRL) and the range error ratio (RER) give excellent assessments of the models with the PRL ratios lower than 2 and the RER values greater than 10. The NIRS models were validated using a completely independent set of samples and have coefficients of determination (R2V, CP = 0.99, NDF = 0.91, ADF = 0.95, WSC = 0.91) and ratio of prediction to deviation (RPD, CP = 9.37, NDF = 3.44, ADF = 4.40, WSC = 3.39). The result suggested that routine screening for forage quality parameters with large numbers of samples is available with the NIRS model in Italian ryegrass breeding programs, as well as facilitating graziers to monitor the forage development stage for improving grazing efficiency.
Segmentation and classification of colon glands with deep convolutional neural networks and total variation regularization
Authors: Kainz Philipp , Pfeiffer Michael , Urschler Martin
Published: October 2017

Segmentation of histopathology sections is a necessary preprocessing step for digital pathology. Due to the large variability of biological tissue, machine learning techniques have shown superior performance over conventional image processing methods. Here we present our deep neural network-based approach for segmentation and classification of glands in tissue of benign and malignant colorectal cancer, which was developed to participate in the GlaS@MICCAI2015 colon gland segmentation challenge. We use two distinct deep convolutional neural networks (CNN) for pixel-wise classification of Hematoxylin-Eosin stained images. While the first classifier separates glands from background, the second classifier identifies gland-separating structures. In a subsequent step, a figure-ground segmentation based on weighted total variation produces the final segmentation result by regularizing the CNN predictions. We present both quantitative and qualitative segmentation results on the recently released and publicly available Warwick-QU colon adenocarcinoma dataset associated with the GlaS@MICCAI2015 challenge and compare our approach to the simultaneously developed other approaches that participated in the same challenge. On two test sets, we demonstrate our segmentation performance and show that we achieve a tissue classification accuracy of 98% and 95%, making use of the inherent capability of our system to distinguish between benign and malignant tissue. Our results show that deep learning approaches can yield highly accurate and reproducible results for biomedical image analysis, with the potential to significantly improve the quality and speed of medical diagnoses.
Alpha-arylphorin is a mitogen in the Heliothis virescens midgut cell secretome upon Cry1Ac intoxication

Published: October 2017

Insecticidal crystal (Cry) proteins produced by the bacterium Bacillus thuringiensis (Bt) target cells in the midgut epithelium of susceptible larvae. While the mode of action of Cry toxins has been extensively investigated, the midgut response to Cry intoxication and its regulation are not well characterized. In this work, we describe the secreted proteome (secretome) of primary mature midgut cell cultures from Heliothis virescens larvae after exposure to Cry1Ac toxin compared to control buffer treatment. The Cry1Ac-induced secretome caused higher proliferation and differentiation and an overall reduction in total cell mortality over time in primary H. virescens midgut stem cell cultures when compared to treatment with control buffer secretome. Differential proteomics identified four proteins with significant differences in abundance comparing Cry1Ac-treated and control secretomes. The most significant difference detected in the Cry1Ac secretome was an arylphorin subunit alpha protein not detected in the control secretome. Feeding of purified alpha-arylphorin to H. virescens larvae resulted in midgut hyperplasia and significantly reduced susceptibility to Cry1Ac toxin compared to controls. These data identify alpha-arylphorin as a protein with a new putative role in the midgut regeneration process in response to Cry1Ac intoxication and possibly pathogen/abiotic stress, identifying alpha-arylphorin as a potential gene to target with insecticidal gene silencing for pest control.

Authors: Matias Esdras Matheus , Carvalho Aline Vieira
Published: October 2017

Proposto justificado do tema: A proposta deste artigo foi alinhar perspectivas teóricas e metodológicas da Micro-História com aportes dos estudos no campo do Turismo para entender as transformações das microrrealidades do município de São Miguel do Gostoso (Rio Grande do Norte). Microrrealidades são histórias de pessoas comuns que traduzem e elucidam aspectos microscópicos de um complexo quadro de vida. Objetivo: Analisar as transformações socioculturais da localidade transformadas pelo fenômeno turístico a partir das microrrealidades locais. Design, metodologia e abordagem: No campo metodológico aliou-se a análise qualitativa com a observação direta participante, a análise documental e a investigação do material audiovisual sobre a cidade. Entrevistou-se 52 indivíduos que tiveram alguma representatividade na história da cidade, que não assumiam nenhum cargo oficial e vivenciaram as mudanças decorrentes entre 1993 e 2016. O recorte deste artigo foi de 17 entrevistados. Resultados e originalidade: Os resultados da pesquisa ressaltam que houve transformações relevantes nas microrrealidades socioculturais dos entrevistados. Os impactos mais proeminentes foram: esvaziamento das tradições culturais, hábitos alimentares e linguagem. Por outro lado, contribuições positivas foram enumeradas quanto à pluralidade de culturas e engajamento social. Concluiu-se que as microrrealidades socioculturais foram transformadas pelo fluxo turístico, definindo o turismo como a principal atividade econômica da região e relocando as forças de trabalho. A relevância e originalidade deste estudo é a aliança entre Micro-História e Turismo, quase inexistente nas investigações científicas.
Variability of Indonesian Throughflow and Borneo Runoff During the Last 14 kyr
Authors: Hendrizan Marfasran , Kuhnt Wolfgang , Holbourn Ann
Published: October 2017

We present a high‐resolution (~20 to 100 years temporal resolution) reconstruction of hydrological changes in the Makassar Strait over the last 14 kyr from Core SO217‐18517 retrieved off the Mahakam Delta (1°32.198′S, 117°33.756′E; 698 m water depth) during the SO217 Makassar‐Java Cruise. Sea surface temperatures, based on Mg/Ca of Globigerinoides ruber and alkenone UK′37, and seawater δ18O reconstructions, based on G. ruber δ18O and Mg/Ca, in combination with sortable silt grain size measurements and X‐ray fluorescence (XRF) core scanner derived elemental data provide evidence for increased precipitation during the Bølling‐Allerød (BA) and early Holocene and for warmer and more saline surface waters and a decrease in the intensity of the Indonesian Throughflow (ITF) during the Younger Dryas (YD). XRF derived Log (Zr/Rb) records, sortable silt data and increased sedimentation rates indicate decreased winnowing, interpreted as a slowdown of the ITF thermocline flow during the YD. We attribute this decline in ITF intensity to slowdown of the Atlantic meridional overturning circulation during the YD. We suggest that changes in Makassar Strait surface hydrology during this interval of Northern Hemisphere cooling and Southern Hemisphere warming were related to a southward displacement of the Intertropical Convergence Zone.
Buffering of Ocean Export Production by Flexible Elemental Stoichiometry of Particulate Organic Matter
Authors: Tanioka Tatsuro , Matsumoto Katsumi
Published: October 2017

One of the most important factors that determine the ocean‐atmosphere carbon partitioning is the sinking of particulate organic matter (POM) from the surface ocean to the deep ocean. The amount of carbon (C) removed from the surface ocean by this POM export production depends critically on the elemental ratio in POM of C to nitrogen (N) and phosphorus (P), two essential elements that limit productivity. Recent observations indicate that P:N:C in marine POM varies both spatially and temporally due to chemical, physical, and ecological dynamics. In a new approach to predicting a flexible P:C ratio, we developed a power law model with a stoichiometry sensitivity factor, which is able to relate P:C of POM to ambient phosphate concentration. The new factor is robust, measurable, and biogeochemically meaningful. Using the new stoichiometry sensitivity factor, we present a first‐order estimate that P:C plasticity could buffer against a generally expected future reduction in global carbon export production by up to 5% under a future warming scenario compared to a fixed, Redfield P:C. Further, we demonstrate that our new stoichiometry model can be implemented successfully and easily in a global model to reproduce the large‐scale P:N:C variability in the ocean.

The lack of long‐term, highly resolved (annual to subannual) and absolutely dated baseline records of marine variability extending beyond the instrumental period (last ~50–100 years) hinders our ability to develop a comprehensive understanding of the role the ocean plays in the climate system. Specifically, without such records, it remains difficult to fully quantify the range of natural climate variability mediated by the ocean and to robustly attribute recent changes to anthropogenic or natural drivers. Here we present a 211 year (1799–2010 C.E.; all dates hereafter are Common Era) seawater temperature (SWT) reconstruction from the northeast Atlantic Ocean derived from absolutely dated, annually resolved, oxygen isotope ratios recorded in the shell carbonate (δ18Oshell) of the long‐lived marine bivalve molluskGlycymeris glycymeris. The annual record was calibrated using subannually resolved δ18Oshellvalues drilled from multiple shells covering the instrumental period. Calibration verification statistics and spatial correlation analyses indicate that the δ18Oshellrecord contains significant skill at reconstructing Northeast Atlantic Ocean mean summer SWT variability associated with changes in subpolar gyre dynamics and the North Atlantic Current. Reconciling differences between the δ18Oshelldata and corresponding growth increment width chronology demonstrates that 68% of the variability inG.glycymerisshell growth can be explained by the combined influence of biological productivity and SWT variability. These data suggest thatG.glycymeriscan provide seasonal to multicentennial absolutely dated baseline records of past marine variability that will lead to the development of a quantitative understanding of the role the marine environment plays in the global climate system.
Cure Frailty Models
Authors: Yuan Mengdie , Zhang Xiangmin , Diao Guoqing
Published: October 2017

A cure frailty model is often used to model correlated survival data when not all the subjects would develop the event of interest. In this article, we describe the components of a cure frailty model and review the development of the model. A mixture cure frailty model and its estimation approach are then illustrated assuming a Cox model and the shared gamma frailty for the uncured subpopulation. Applications of various cure frailty models are also summarized. We conclude the article with brief discussions of the challenges and opportunities for future research in this area.
