Due to the worldwide trend of internationalization of higher education, in 2011 the Brazilian government launched Science Without Borders (SwB), a federal program that aimed to qualify national science through student mobility. As a result of the large number of students being sent abroad, foreign language training became essential to the success of the program. In order to ensure the training of English-speaking students and ensure that they could study in English-speaking universities, English without Borders (EwB) was created with three main actions: application of proficiency tests, online and face-to-face courses. It is known that the English language is understood as a lingua franca by participating in different discursive spheres, economy, politics, and business, therefore, the current English language courses should prepare students for the complexity of language and its usage. In this way, our objective is to investigate how the courses work and how the SwB candidates are trained to use the English language in a foreign study context. Since the advent of globalization and the emergence of a vast English teaching industry, language has gained a utilitarian connotation and has come to be understood as a consumer good submissive to the laws of the labor market. In light of these findings, we analyzed the official and proposed documents of the EwB to understand the governmental proposal, we applied a questionnaire to the coordinators of the on-site courses and we, discursively, analyzed the media publications about the programs. With the linking of the different methods used in the research, we sought to explain EwB's submission to the SwB agenda and interests and, as a result, the political-social place in which the program was inserted in the face of the challenges brought by the internationalization of higher education.
Diante da tend?ncia mundial de internacionaliza??o da educa??o superior, o governo brasileiro lan?ou, em 2011, o Ci?ncia sem Fronteiras (CsF), programa federal que tinha por objetivo qualificar a ci?ncia nacional por meio da mobilidade estudantil. Com a grande quantidade de alunos sendo enviados ao exterior, a forma??o em l?ngua estrangeira passou a ser essencial para o ?xito do programa. No intuito de garantir a forma??o dos alunos em l?ngua inglesa para que pudessem estudar em universidades angl?fonas, o Ingl?s sem Fronteiras (IsF) foi criado com tr?s a??es principais: aplica??o de testes de profici?ncia, oferecimento de cursos presenciais e online. Sabendo que a l?ngua inglesa ? entendida como uma l?ngua franca por participar de diferentes esferas discursivas, da economia, da pol?tica, dos neg?cios, compreendemos que os cursos de l?ngua inglesa da atualidade devem preparar os alunos para a complexidade que constitui a l?ngua e o uso dela. Dessa forma, nosso objetivo ? investigar como os cursos funcionam e de que maneira os candidatos do CsF s?o formados para o uso da l?ngua inglesa em contexto de estudo estrangeiro, uma vez que, diante do advento da globaliza??o e da emerg?ncia de uma vasta ind?stria de ensino de ingl?s, a l?ngua ganhou uma conota??o utilitarista e passou a ser entendida como um bem de consumo submisso ?s leis do mercado de trabalho. Diante dessas constata??es, analisamos os documentos oficiais e propositivos do IsF, para entender a proposta governamental; aplicamos um question?rio aos coordenadores dos cursos presenciais e analisamos, discursivamente, as publica??es midi?ticas acerca dos programas. Buscamos, com o encadeamento dos diferentes m?todos empregados na pesquisa, explicitar a submiss?o do IsF ? agenda e interesses do CsF e, portanto, o lugar pol?tico-social em que o programa se inseriu em face dos desafios propostos pela internacionaliza??o da educa??o superior.

Повний текст джерелаCross-laminated timber (CLT) is a rather new construction material that has increased its popularity and usage significantly within the building industry in the past years. In timber buildings, the connections are one of the most challenging parts to design. Thus, there are high demands put on structural engineers to make a safe and economic design. Today structural engineers have no specific and clear guideline that they can use as help for design of connections in CLT-buildings. By reviewing the most common CLT-handbooks, comparing them with each other, and picking out the best parts from each of the handbooks, a new guideline for design of connections in CLT-structures was developed in this thesis with complementary design examples. The guidelines main purpose is to act as help for the structural engineer when designing connections in CLT-structures. It is indented that the guideline acts as basis for the development of a future CLT-handbook with a collection of supporting calculation examples.

Повний текст джерелаResearch in the area of teacher training in English as a Foreign Language (CELANI, 2003, 2004, 2010; PAIVA, 2000, 2003, 2005; VIEIRA-ABRAH?O, 2010) articulates the complexity of beginning teachers classroom contexts aligned with teaching language as a social and professional practice of the teacher in training. To better understand this relationship, the present study is based on a corpus of transcribed interviews and questionnaires applied to 28 undergraduate students majoring in Letters/English emphasis, at a public university located in the interior of the Western Amazon region, soliciting their opinions about the reforms made in the curriculum of this Major. Interviews and questionnaires were used as data collection instruments to trace a profile of the students organized in Group 1, with freshmen and sophomore undergraduates who are following the 2009 curriculum, and Group 2, with junior and senior undergraduates who are following the 2006 curriculum. The objectives are to identify, to characterize and to analyze the types of pronouns, roles and social actors represented in the opinions of these students in relation to their teacher training curriculum. The theoretical support focuses on the challenge of historical and contemporary routes from English teachers initial education programs (MAGALH?ES; LIBERALLI, 2009; PAVAN; SILVA, 2010; ALVAREZ, 2010; VIANA, 2011; PAVAN, 2012). Our theoretical perspective is based on the Systemic Functional Grammar of Halliday (1994), Halliday and Hasan (1989), Halliday and Matthiessen (2004), Eggins (1994; 2004) and Thompson (2004). We focus on the concept of the Interpersonal meaning, specifically regarding the roles articulated in the studies by Delu (1991), Thompson and Thetela (1995), and in the Portuguese language such as Ramos (1997), Silva (2006) and Cabral (2009). Moreover, we ascribe van Leeuwen s (1997; 2003) theory of Representation of Social Actors as a theoretical framework in order to identify the sociological aspect of social actors represented in the students discourse. Within this scenario, the analysis unfolds on three levels: grammatical (pronouns), semantic (roles), and discursive (social actors). For the analysis of interpersonal realizations present in the students opinions, we use the computational program WordSmith Tools (SCOTT, 2010) and its applications Wordlist and Concord to quantify the occurrences of the pronouns I, You and They, which characterize the roles and social actors of the corpus. The results show that the students assigned the following roles to themselves: (i) apprentice to express their initial process of English language learning; (ii) freshman to reveal their choice of Major in Letters/English emphasis; (iii) future teacher to relate their expectations towards a practicing professional. To assign the roles to professors in the major, the students used the metaphor of modality (I think) to indicate the relationship of teacher training, while they are in the role of a student and as a future teacher. From these evidences the representation of the students as social actors emerges in roles such as: (i) active roles; (ii) passive roles and (iii) personalized roles. The social actors represented in the opinions of the students reflect the inclusion of these roles assigned to the actions expressed about their experiences and expectations derived from their teacher training classroom
Pesquisas na ?rea de forma??o de professores de ingl?s como l?ngua estrangeira (CELANI, 2003, 2004, 2010; PAIVA, 2000, 2003, 2005; VIEIRA-ABRAH?O, 2010) dimensionam a complexidade de contextos da sala de aula de forma??o inicial em aliar o ensino da l?ngua com a pr?tica social e profissional do futuro professor. Como forma de fornecer subs?dios para a compreens?o dessa rela??o, a presente pesquisa baseia-se em um corpus composto de entrevistas transcritas de 28 alunos de um Curso de Letras/Ingl?s (CLI) de uma universidade p?blica localizada no interior da Amaz?nia Ocidental e suas opini?es acerca da reformula??o do curr?culo do curso. Os instrumentos de coleta de dados utilizados foram entrevistas e question?rios para tra?ar o perfil dos alunos do CLI concentrados em Grupo 1, com os alunos do 1? e 3? per?odos do curr?culo de 2009, e o Grupo 2, com os alunos do 5? e 7? per?odos do curr?culo de 2006. Os objetivos propostos buscam identificar, caracterizar e analisar os tipos de pronomes, os pap?is e os atores sociais representados nas opini?es dos alunos em rela??o ao curr?culo de sua forma??o inicial. O aporte te?rico enfoca os desafios do percurso hist?rico e contempor?neo dos programas de forma??o inicial de professores de l?nguas (MAGALH?ES; LIBERALLI, 2009; PAVAN; SILVA, 2010; ALVAREZ, 2010; VIANA, 2011; PAVAN, 2012). Para a perspectiva te?rica e anal?tica, apoiamo-nos na Gram?tica Sist?mico-Funcional (GSF) de Halliday (1994), Halliday e Hasan (1989), Halliday e Matthiessen (2004), Eggins (1994; 2004) e Thompson (2004). Focamos no conceito da Interpessoalidade, especificamente acerca dos pap?is abordados por Delu (1991), Thompson e Thetela (1995), e trabalhos em l?ngua portuguesa como os de Ramos (1997), Silva (2006) e Cabral (2009). A Teoria da Representa??o dos Atores Sociais de van Leeuwen (1997; 2003) contempla a base te?rica para identificarmos o car?ter sociol?gico dos atores sociais representados no discurso dos alunos. Com este panorama, o percurso proposto para an?lise percorre tr?s n?veis principais: os pronomes (n?vel gramatical), os pap?is (n?vel sem?ntico) e os atores sociais (n?vel discursivo). Para a an?lise das marcas interpessoais presentes nas opini?es dos alunos, utilizamos o programa computacional WordSmith Tools (SCOTT, 2010), e suas ferramentas Wordlist (Lista de Palavras) e Concord (Concordanciador) para quantificar as ocorr?ncias dos pronomes: Eu, Voc? e Eles, que permitam caracterizar os pap?is e os atores sociais no corpus. Os resultados demonstram que os alunos atribuem a si mesmos os seguintes pap?is: (i) aprendiz para expressar o processo inicial de seu aprendizado com o ingl?s; (ii) ingressante na licenciatura para expor suas escolhas em cursar Letras/Ingl?s; (iii) futuro professor para relacionar suas expectativas com a pr?tica profissional. Para atribuir os pap?is aos professores e o curso, os alunos utilizam a met?fora de modalidade, Eu acho que para marcar as rela??es da forma??o inicial como aluno e futuro professor. Destas evid?ncias emergem os atores sociais representados pelos alunos em: (i) pap?is ativos; (ii) pap?is passivos e (iii) pap?is personalizados. Esses atores sociais representados nas opini?es dos alunos refletem a inclus?o dos pap?is atribu?dos para as a??es expressas acerca das experi?ncias e expectativas oriundas da sala de aula de sua forma??o

Повний текст джерелаMassively Multiplayer Online Role-Playing Games (MMORPGs) are role-playing games that, through the Internet, can integrate thousands of players interacting at the same time in at least one virtual world. This way, these games can provide, further than fun, a greater familiarity with the additional language and opportunity to improve the linguistic proficiency in a real context. Hence, what is proposed in this study is extended knowledge about the learning of an additional language mediated by MMORPGs for teachers to know how, if relevant, to present, use or encourage this practice to their students. Based on this major purpose, we seek to answer the following research questions: (a) what distinguishes the learning profile of the gamers and non-gamers; (b) if MMORPGs can, through a hybrid and systematic approach, assist the development of proficiency of the additional language and (c) what the think-aloud protocols show about the learning mediated by the MMORPG Allods Online. Following an experimental method (NUNAN, 1997), 16 students of the curricular component Reading and Writing Practices in English Language have comprised the control group and 17 students of the same class formed the experimental group and were submitted to a pre and post-test adapted from the Key English Test (KET) by the Cambridge University (2008). The tests were conducted before and after a period of 5 weeks of 3 hours of practice with Allods Online a week (experimental group), and classes of the curricular component (both groups). A quantitative analysis of the questionnaires about the exposure to English profiles of the participants, a quantitative analysis of the tests scores and a qualitative analysis of the thinkaloud protocols collected during the experiment were conducted based on the theories of (a) motivation (GARDNER, 1985, WILLIAMS & BURDEN, 1997, BROWN, 2007, HERCULANO-HOUZEL, 2005); (b) active learning (GASS, 1997, GEE, 2008, MATTAR, 2010); (c) interaction and collaborative learning (KRASHEN, 1991, GASS, 1997, VYGOTSKY, 1978); (d) situated learning (DAMASIO, 1994; 1999; 2003, BROWN, 2007, GEE, 2003) and (e), tangential learning (PORTNOW, 2008; MATTAR, 2010). The results indicate that the participants of the experimental group (gamers) seem to be more engaged in tangential English learning activities, such as playing games, listening to music in English, communicating with foreigners and reading in English. We also deduced that the period of experiment possibly generated positive results on the gamers proficiency scores, mainly in the parts related to orthographic development, reading and comprehension, writing with focus on content and orthographic accuracy. Lastly, the think-aloud protocols presented evidences that the gamers have engaged in active English language learning, they have interacted in English with other players, and learned linguistic aspects through the experience with the MMORPG Allods Online
Os Massively Multiplayer Online Role-Playing Games (MMORPGs) s?o jogos de interpreta??o de personagem que, atrav?s da Internet, podem integrar milhares de jogadores interagindo ao mesmo tempo em pelo menos um mundo virtual. Desta forma, esses jogos podem proporcionar, al?m de divers?o, um maior conv?vio com a l?ngua inglesa e a oportunidade de aprimorar a profici?ncia lingu?stica dentro de um contexto real. Por isso, o que se prop?e neste estudo ? um maior conhecimento sobre a aprendizagem de l?ngua adicional mediada por MMORPGs para que os professores saibam como, se relevante, apresentar, utilizar ou incentivar essa pr?tica junto a seus alunos. Com base neste objetivo principal, procuramos responder as seguintes perguntas de perquisa: (a) o que distingue o perfil de exposi??o ? l?ngua inglesa dos gamers e non-gamers; (b) se os MMORPGs podem, por meio de uma pr?tica h?brida e sistem?tica, auxiliar no desenvolvimento da profici?ncia na l?ngua adicional e (c) o que os protocolos think-aloud evidenciam acerca da aprendizagem mediada pelo MMORPG Allods Online. Seguindo o m?todo experimental (NUNAN, 1997), 16 alunos do componente curricular Pr?ticas de Leitura e Produ??o Escrita em L?ngua Inglesa fizeram parte do grupo controle e 17 alunos da mesma turma compuseram o grupo experimental e foram submetidos a um pr? e p?s-teste adaptados do Key English Test (KET) da Universidade de Cambridge (2008). Os testes foram administrados antes e depois de um per?odo de 5 semanas com 3 horas por semana de experimento com o game Allods Online (grupo experimental), e de aulas do componente curricular (ambos os grupos). Uma an?lise quantitativa dos question?rios sobre os perfis de exposi??o ? l?ngua inglesa dos participantes, uma an?lise quantitativa das notas dos testes e uma an?lise qualitativa de protocolos thinkaloud coletados durante o experimento foram feitas com base nas teorias de (a) motiva??o (GARDNER, 1985, WILLIAMS & BURDEN, 1997, BROWN, 2007, HERCULANOHOUZEL, 2005); (b) aprendizagem ativa (GASS, 1997, GEE, 2008, MATTAR, 2010); (c) intera??o e aprendizagem colaborativa (KRASHEN, 1991, GASS, 1997, VYGOTSKY, 1978); (d) aprendizagem situada (DAMASIO, 1994; 1999; 2003, BROWN, 2007, GEE, 2003) e (e), aprendizagem tangencial (PORTNOW, 2008 E MATTAR, 2010). Os resultados indicam que os participantes do grupo experimental (gamers) parecem ser mais engajados em atividades tangenciais de aprendizagem de l?ngua inglesa, como jogar games, ouvir m?sica em ingl?s, comunicar-se com estrangeiros e ler em ingl?s. Tamb?m conclu?mos que o per?odo de experimento pode ter gerado resultados positivos nas notas dos testes dos gamers, principalmente nas partes relacionadas (a) ao desenvolvimento ortogr?fico, leitura e interpreta??o; (b) ? escrita com foco no conte?do e (c) ? acur?cia ortogr?fica. Por fim, os protocolos think-aloud apresentam evid?ncias de que os gamers engajaram-se na aprendizagem ativa de l?ngua inglesa, interagiram em ingl?s com outros jogadores e aprenderam aspectos lingu?sticos atrav?s da experi?ncia com o MMORPG Allods Online

Повний текст джерелаThis research has as its theoretical and methodological assumptions (1) the Narrative Inquiry (CLANDININ; CONNELLY, 2011), (2) the Systemic Functional Grammar (HALLIDAY, 1985, 1994; THOMPSON, 2002; EGGINS, 1994; HALLIDAY; MATTHIESSEN, 2004) and (3) the English for Specific Purposes Approach (ESP - HUTCHINSON; WATERS, 1987; CELANI, 2005; RAMOS, 2005), and its overall objective is to survey the meanings construed by the participants who are ESP practitioners and have not received a specific education to teach this approach at their undergraduation. The field texts and therefore the analises were divided into two distinct groups: the first with data generated from a questionnaire applied to nine professors from a federal university in the northeast of Brazil, which contains open and closed questions about their training and their experiences in teaching ESP; the second group, focusing this time on the experiences of three professors from the first group who were still teaching ESP, with data generated from interviews with these participants in addition to the data generated from their autobiographies and from the researcher?s as well. The computational tool WordSmith Tools 6.0 (SCOTT, 2012) was used to select, organize, and quantify data to be analyzed in the first group of texts, identifying the types of Processes and Participants through the Transitivity System (HALLIDAY; MATTHIESSEN, 2004). The Processes which were more used by the professors in the questionnaire were the Material, followed by the Relational and then the Mental ones, indicating that most professors reported their actions related to the teaching of ESP, rated or evaluated the approach, their training to teach it and their experiences, hence, rarely showing their thoughts and emotions about teaching ESP. Most of the nine professors say they carry out needs analysis, but not all do it according to the authors cited by them or the ones that are considered a reference in this area, such as the ones used in this research as reference. Similarly, their definitions and conceptions of ESP, in most cases, differed from these authors. All the professors claim not having had specific education to teach ESP at the undergraduation. When examining the stories of the four teachers, in the second group of the field texts, based on meaning composition according to Ely, Vinz, Downing and Anzul (2001), it was revealed that the kind of knowledge they report using when they teach ESP is related to their Personal Practical Knowledge and their Professional Knowledge (ELBAZ, 1983; CLANDININ, 1988). In their autobiographies, metaphors were also identified and they represent their concepts of teaching and being a teacher. Through this research, we hope to contribute to the understanding of what teaching ESP might mean for professors in the researched context and also to the continuing education of ESP practitioners, as well as to a review of the curricula in the English language undergraduate courses and of the role of ESP in the training of these professionals
A presente pesquisa tem como pressupostos te?rico-metodol?gicos (1) a Pesquisa Narrativa (PN CLANDININ; CONNELLY, 2011), (2) a Gram?tica Sist?mico-Funcional (GSF HALLIDAY, 1985, 1994; THOMPSON, 2002; EGGINS, 1994; HALLIDAY; MATTHIESSEN, 2004) e (3) a abordagem de ensino de Ingl?s para Fins Espec?ficos (IFE HUTCHINSON; WATERS, 1987; CELANI, 2005; RAMOS, 2005), com o objetivo geral de fazer um levantamento dos sentidos constru?dos pelos professores participantes sobre o IFE, a forma??o espec?fica que receberam para ministr?-lo e a sua experi?ncia em ensin?-lo no n?vel superior. Os textos de campo e, por conseguinte, as an?lises, foram organizados em dois grupos distintos: o primeiro com dados gerados a partir de um question?rio aplicado a nove professores de uma institui??o p?blica no nordeste brasileiro, contendo perguntas abertas e fechadas a respeito de sua forma??o e de suas experi?ncias em ministrar a disciplina de Ingl?s Instrumental e o segundo grupo, a partir do enfoque nas experi?ncias de tr?s professoras do primeiro grupo que continuavam ensinando IFE, com dados gerados por entrevistas com essas participantes e por suas autobiografias, al?m dos dados gerados pela autobiografia da pr?pria pesquisadora, tamb?m participante da pesquisa. Foi usada a ferramenta computacional WordSmith Tools 6.0 (SCOTT, 2012) para selecionar, organizar e quantificar os dados a serem analisados no primeiro grupo de textos, identificando-se os tipos de Processos e os Participantes, pelo Sistema de Transitividade (HALLIDAY; MATTHIESSEN, 2004), sendo que os Processos mais usados pelos professores no question?rio foram os Materiais, seguidos dos Relacionais e em terceiro lugar os Mentais, indicando que a maioria relatou mais suas a??es com rela??o ao ensino de IFE, classificou ou definiu a abordagem, sua forma??o e suas experi?ncias do que demonstrou seus pensamentos e emo??es a respeito de ensinar IFE. A maioria dos nove professores afirma fazer a an?lise de necessidades, mas nem todos a fazem de acordo com o que estabelecem os autores por eles citados ou outros autores considerados refer?ncia nessa ?rea, tais como os que usamos nesta pesquisa. Do mesmo modo, suas defini??es e concep??es sobre IFE, na maioria das vezes, diferem das desses autores. Todos os professores participantes alegam n?o ter tido forma??o espec?fica para ensinar IFE na licenciatura. Ao analisar os relatos das quatro professoras do segundo grupo de textos de campo, com base na composi??o de sentidos segundo Ely, Vinz, Downing e Anzul (2001), percebeu-se que o tipo de conhecimento que estas referem usar para ministrar IFE est? relacionado ao Conhecimento Pr?tico Pessoal e ao Conhecimento Profissional (ELBAZ, 1983; CLANDININ, 1988). Em seus relatos, foram identificadas tamb?m imagens que representam suas concep??es a respeito de ensinar e ser professora. Esperamos, atrav?s desta pesquisa, contribuir tanto para a compreens?o do que pode significar ensinar IFE para os professores do contexto pesquisado, como para a forma??o continuada de professores de IFE, assim como para uma revis?o nos curr?culos de Letras e do papel do IFE na forma??o do professor de l?ngua inglesa

Повний текст джерелаThis present work has as objective to analyze the interpretation of the syntactic and semantic meaning performed by third graders in the nominal groups (NGs) with attributive adjectives in the English language in a text of the final exam in the ESP (English for Specific Purposes) discipline. The corpus is made up of 30 exams of two classes from a third grade institution of the biomedical area, corresponding to the basic and advanced levels of the second term in 2006. The text has 24 NGs of different lexical content, a total of 27 NGs in the whole text summing up to 810 analyzed occurrences. The analysis is carried out at the morphologic, syntactic and semantic levels using as theoretical background the traditional and functional grammars (QUIRK et al, 1985; CELSE-MURCIA et al, 1998; TUCKER, 1998), in their semantic aspects, the Semantics (FRAWLEY, 1992) and the Cognitive Linguistics (TAYLOR, 2002). We concluded that the main difficulties were due to the lack of vocabulary and to the use of mother tongue strategies instead of using the top-down strategies for reading a text in English to compensate this gap. We also observed that even when the vocabulary was known, there were difficulties in establishing the semantic and syntactic relations between modifier and noun head. We suggested improvements for the teaching of reading English texts at the third grade grounded in the obtained results such as a more comprehensive study of the several different morphologic and syntactic structures of the NGs with premodifiers and their semantic consequences, an approach of the morphologic, syntactic and semantic aspects of the NGs and the use of both top-down and bottom-up strategies when reading a NG in the English language
Este trabalho tem como objetivo analisar a interpreta??o do significado sint?tico e sem?ntico realizada por alunos universit?rios de Ingl?s Instrumental nos sintagmas nominais (SNs) com adjetivos atributivos na l?ngua inglesa em um texto da prova de final de semestre. O corpus ? constitu?do por 30 provas de duas turmas de uma institui??o de n?vel superior, da ?rea biom?dica, do segundo semestre de 2006, do n?vel b?sico e avan?ado. O texto da prova ? composto por 24 SNs de conte?do lexical diferente, num total de 27 SNs presentes no texto, totalizando 810 ocorr?ncias analisadas. Usamos como pressupostos te?ricos as gram?ticas tradicional (QUIRK et al, 1985) e funcionalista (CELSE-MURCIA et al, 1998; TUCKER, 1998), em seus aspectos sem?nticos, a Sem?ntica (FRAWLEY, 1992) e a Ling??stica Cognitiva (TAYLOR, 2003). Conclu?mos que as maiores dificuldades deveram-se ? falta de vocabul?rio, ao uso inadequado de estrat?gias da L?ngua Materna no lugar de se usar as estrat?gias descendentes de leitura para suprir esta falta. Observamos tamb?m que, mesmo quando se conhecia o vocabul?rio do SN, muitas vezes houve dificuldades em se perceber a rela??o sem?ntica e/ou sint?tica entre os modificadores e o n?cleo do SN acarretando inadequa??es de interpreta??o. Sugerimos melhorias para o ensino da leitura de textos em l?ngua inglesa nas universidades com base nos resultados obtidos, como um estudo mais detalhado das v?rias estruturas morfossint?ticas dos SNs com modificadores antepostos e suas conseq??ncias sem?nticas; uma abordagem conjunta dos aspectos morfol?gico, sint?tico e sem?ntico dos SNs com adjetivos atributivos na l?ngua inglesa e o uso das estrat?gias descendentes juntamente com as ascendentes ao se ler um SN na l?ngua inglesa

O Google Docs (GD) ? um editor online de textos por meio do qual m?ltiplos autores podem trabalhar s?ncrona ou assincronamente em um mesmo documento, o que pode auxiliar no desenvolvimento da habilidade de escrita em ingl?s (WEISSHEIMER; SOARES, 2012). Ao escrever colaborativamente, os aprendizes t?m mais oportunidades para perceber as lacunas na sua produ??o escrita, visto que s?o expostos a mais insumo lingu?stico por parte dos colegas coautores (WEISSHEIMER; BERGSLEITHNER; LEANDRO, 2012), e priorizam o processo de (re)constru??o textual, em detrimento da preocupa??o com o produto final (i.e., o texto pronto) (LEANDRO; WEISSHEIMER; COOPER, 2013). Ademais, no processo de aprendizagem de uma segunda l?ngua (L2), a produ??o de linguagem propicia a consolida??o de conhecimentos existentes e a cria??o de novos conhecimentos (SWAIN, 1985; 1993). Levando isto em considera??o, o presente estudo, de natureza quasi-experimental (NUNAN, 1992) e abordagem mista (D?RNYEI, 2007), objetiva investigar o impacto da escrita colaborativa mediada pela ferramenta GD no desenvolvimento da habilidade de escrita em L?ngua Inglesa (LI) e na percep??o de erros sint?ticos ou noticing (SCHMIDT, 1990). Trinta e quatro licenciandos em Letras/Ingl?s integraram o estudo, sendo 25 no grupo experimental e nove no grupo controle. Ambos os grupos passaram por um pr?-teste e por um p?s-teste para que pud?ssemos medir o noticing de estruturas sint?ticas. Os participantes do grupo experimental foram expostos a uma experi?ncia de aprendizagem h?brida, a qual consistiu em aulas presenciais de leitura e produ??o escrita em LI e na escrita colaborativa de tr?s narrativas completas contadas em 100 palavras, denominadas flash fiction (FF), fora de sala de aula, online por meio do GD, durante 11 semanas. O grupo controle teve igualmente aulas presenciais de leitura e produ??o escrita em LI, por?m n?o praticou nenhum tipo de escrita colaborativa. Analisamos a primeira e a ?ltima narrativa produzida pelos participantes do grupo experimental a fim de medir a acur?cia gramatical, operacionalizada como a quantidade de erros gramaticais a cada 100 palavras (SOUSA, 2014) e a densidade lexical, operacionalizada como a rela??o entre o n?mero de palavras produzidas com propriedades lexicais e o n?mero de palavras produzidas com propriedades gramaticais (WEISSHEIMER, 2007; MEHNERT, 1998). Adicionalmente, os participantes do grupo experimental responderam a um question?rio online sobre a experi?ncia h?brida a qual foram expostos. Os resultados quantitativos mostram que os participantes passaram a produzir textos com mais densidade lexical ap?s 11 semanas de interven??o pedag?gica. J? os resultados quantitativos do noticing e da acur?cia gramatical foram contr?rios ao esperado, por?m nos fornecem insights sobre o modelo de teste, no caso do noticing, e sobre a atitude ? positiva ? dos participantes em rela??o ? escrita colaborativa de FF. Os resultados qualitativos evidenciam a utilidade da escrita colaborativa mediada por tecnologia no processo de aprendizagem de L2.
Google Docs (GD) is an online word processor with which multiple authors can work on the same document, in a synchronous or asynchronous manner, which can help develop the ability of writing in English (WEISSHEIMER; SOARES, 2012). As they write collaboratively, learners find more opportunities to notice the gaps in their written production, since they are exposed to more input from the fellow co-authors (WEISSHEIMER; BERGSLEITHNER; LEANDRO, 2012) and prioritize the process of text (re)construction instead of the concern with the final product, i.e., the final version of the text (LEANDRO; WEISSHEIMER; COOPER, 2013). Moreover, when it comes to second language (L2) learning, producing language enables the consolidation of existing knowledge as well as the internalization of new knowledge (SWAIN, 1985; 1993). Taking this into consideration, this mixed-method (D?RNYEI, 2007) quasi-experimental (NUNAN, 1999) study aims at investigating the impact of collaborative writing through GD on the development of the writing skill in English and on the noticing of syntactic structures (SCHMIDT, 1990). Thirtyfour university students of English integrated the cohort of the study: twenty-five were assigned to the experimental group and nine were assigned to the control group. All learners went through a pre-test and a post-test so that we could measure their noticing of syntactic structures. Learners in the experimental group were exposed to a blended learning experience, in which they took reading and writing classes at the university and collaboratively wrote three pieces of flash fiction (a complete story told in a hundred words), outside the classroom, online through GD, during eleven weeks. Learners in the control group took reading and writing classes at the university but did not practice collaborative writing. The first and last stories produced by the learners in the experimental group were analysed in terms of grammatical accuracy, operationalized as the number of grammar errors per hundred words (SOUSA, 2014), and lexical density, which refers to the relationship between the number of words produced with lexical properties and the number of words produced with grammatical properties (WEISSHEIMER, 2007; MEHNERT, 1998). Additionally, learners in the experimental group answered an online questionnaire on the blended learning experience they were exposed to. The quantitative results showed that the collaborative task led to the production of more lexically dense texts over the 11 weeks. The noticing and grammatical accuracy results were different from what we expected; however, they provide us with insights on measurement issues, in the case of noticing, and on the participants? positive attitude towards collaborative writing with flash fiction. The qualitative results also shed light on the usefulness of computer-mediated collaborative writing in L2 learning.

Повний текст джерелаThis work has risen from the researcher s pedagogical practice at a technical school in Natal, and it aims to observ how affectiveness is noticed by the students in their English classes, since we can have an idea of technicist teaching, which foccus on the acquisition of technical abilities. As cognition and affectiveness are considered indivisible elements in this research, we tried to identify the linguistic signs that express the students representations about affectiveness in their English classes. We used the Systemic Functional Linguistics approach to study the Ideational metafunction of Halliday (1994), by means of the transitivity system, to show how the clauses are used to illustrate these representations, and the interpersonal metafunction, that deals with the relationship between the teacher and the students. We tried to identify the most common processes (HALLIDAY, 1994) mentioned by the 68 students who participated in this work. We used learning narratives (BARCELOS, 2006) submitted to Wordsmith Tools computing program (SCOTT, 2009), whose results indicate the most frequent lexical items found in their narratives. The lexical choices seem to indicate that affectiveness is noticed as a composing element of the English classes in that school. There are representations of interacting classes, where the students needs are considered. These representations are built in the relationship of the students and the teacher, and they are grammatically realized by means of the polarity adjunct no , the intensity adjunct very , and the nominal group the teacher . The relational and mental processes (be) and (like) are the most used in their narratives, and we also observe that affectiveness and disponibility to help the students are considered the most important attitudes in their representations. The Appraisal system is used to analise the choices related to the attitudes and judgement of the students, that show appreciation for interacting classes, but there is still authorithary berhavior from the teacher in the English classes

Este trabalho tem como objetivo identificar o conceito est?tico de humor subjacente ?s discuss?es travadas pela cr?tica liter?ria brasileira do s?culo XIX em torno de Mem?rias p?stumas (GUIMAR?ES, 2004), (ROMERO, 1897). No intento de atingi-lo, fez-se necess?rio percorrer dois caminhos: o primeiro deles, acompanhando o processo de estrutura??o do conceito de humor ingl?s at? sua manifesta??o em Tristram Shandy (KLIBANSKY, 1979); (WATT, 2010); o segundo, identificando as particularidades da manifesta??o do humor ingl?s em Mem?rias p?stumas e a din?mica alimentada pela cr?tica brasileira com a quest?o da identidade nacional (CANDIDO, .2012), (MAGALH?ES J?NIOR, 2008).
This paper aims to identify the aesthetic concept of humor underlying Brazilian 19th-century critical readings of Epitaph of a small winner, by Machado de Assis (GUIMAR?ES, 2004; ROMERO, 1897). First, we follow the structuring process of the concept of English humour from the Hippocratic theory of humors through Tristram Shandy, by Laurence Sterne (KLIBANSKY; PANOFSKY; SAXL, 1979; WATT, 2010). Finally, we analyze it in Epitaph of a small winner considering the concept of national identity in Brazilian literary milieu at the time (CANDIDO, 2012; MAGALH?ES J?NIOR, 2008).

Este estudo qualiquantitativo se prop?e a analisar escolhas l?xico-gramaticais realizadas em 18 textos escritos do g?nero Discussion produzidos por nove alunos de um instituto de idiomas pertencente a uma universidade federal no nordeste do Brasil. Os textos foram gerados em uma turma de ingl?s n?vel IV e em uma turma de conversa??o em dois momentos no decorrer de 2015.2 e submetidos ? an?lise qualitativa por meio do sistema de transitividade proposto pela lingu?stica sist?mico-funcional (HALLIDAY, 1994; EGGINS, 2004; HALLIDAY; MATTHIESSEN, 2014). Na an?lise quantitativa, utilizou-se a ferramenta Wordsmith Tools 5.0 (SCOTT, 2010) para identificar e quantificar os processos e os participantes das ora??es. Os resultados mostram que os processos mais usados na turma de n?vel IV foram is/are, like e have enquanto os processos mais recorrentes na turma de conversa??o foram is/are, think e do. Na primeira turma, o processo like sugere que os alunos concebem os assuntos tratados como quest?es de prefer?ncia pessoal enquanto, na segunda turma, o processo think revela a interpreta??o dos temas como quest?es de cren?as pessoais. Quanto aos participantes nas ora??es, as maiores recorr?ncias da turma de n?vel IV foram people, weekend, I e we, enquanto we, waste, problem, garbage, you e women foram mais recorrentes na turma de conversa??o. O uso recorrente de I na primeira turma mostra a estrat?gia dos alunos de se revelarem como autores a fim de expressarem sua opini?o. Por outro lado, na segunda turma, o uso de you consiste numa estrat?gia para chamar a aten??o do leitor diretamente. Tais resultados mostram que a identifica??o e a an?lise dos participantes e dos processos nas ora??es por meio da transitividade s?o feedback ?til para os alunos, seja na reescrita ou na produ??o de novos textos.
This qualiquantitative study analyzes lexicogrammatical choices realized in 18 written texts from the Discussion genre produced by nine students of a language institute at a federal university in Northeastern Brazil. The texts were generated in a Level IV English class and in a conversation class in two moments in 2015.2 and submitted to a qualitative analysis by using the transitivity system proposed by systemic-functional linguistics (HALLIDAY, 1994; EGGINS, 2004; HALLIDAY; MATTHIESSEN, 2014). In the quantitative analysis, we used the Wordsmith Tools 5.0 (SCOTT, 2010) program to identify and quantify the processes and the participants of the clauses. The results show that the most frequent processes in the level IV class were is/are, like and have whereas the most frequent processes in the conversation class were is/are, think, and do. In the first class, the process like suggests that the students conceive the subjects in question as matters of personal preference while, in the second class, the process think reveals the interpretation of the themes as matters of personal beliefs. Regarding the participants in the clauses, the more frequent recurrences in the level IV class were people, weekend, I and we, while we, waste, problem, garbage, you and women were more recurrent in the conversation class. The recurrent use of I in the first class shows the strategy of the students in revealing themselves as authors to express their opinions. On the other hand, in the second class, the use of you consists of a strategy to call the reader?s attention directly. These results show that the identification and the analysis of participants and processes in the clauses by means of transitivity are useful feedback for the students when rewriting or producing new texts.

Esta dissertação trata de duas pesquisas sociolinguísticas (Pesquisa I e Pesquisa II) realizadas entre os Asuriní do Tocantins (PA), no âmbito do Projeto A LÍNGUA ASURINÍ DO TOCANTINS: UM PROJETO PILOTO PARA A METODOLOGIA GERAL DO INVENTÁRIO NACIONAL DA DIVERSIDADE LINGUÍSTICA, do Inventário Nacional da Diversidade Linguística (INDL)/MinC/IPHAN. O presente estudo segue a abordagem sobre línguas em situação de obsolescência, como as propostas por Dorian (1981), Thomason (2001a; 2001b) e Campbel e Muntzel (1989), as quais fundamentaram a estruturação da Pesquisa I, bem como adotou o instrumento organizado por Maher (2007), fundamentando-se em seus estudos (1996, 2008), na Pesquisa II; a proposta de Maher parte do pressuposto de que “identidade e repertório verbal relacionam-se com o contexto socio-histórico em que os indivíduos se inserem” (DELL HYMES, 1984). O objetivo deste estudo foi o de realizar um diagnóstico do grau de vitalidade da Língua Asuriní do Tocantins, da sua situação sociolinguística atual, com ênfase nas atitudes lingüísticas e anseios de seus falantes com respeito à sua língua ancestral. A expectativa é que esse diagnóstico possa contribuir para a formulação de metodologias do INDL, que por sua vez estimulará a criação de políticas públicas voltadas ao fortalecimento das línguas e culturas dos povos indígenas do Brasil. _______________________________________________________________________________ ABSTRACT
This thesis is about two sociolinguistic researches (Research I and Research II), applied among the Asuriní do Tocantins, a Tupí indigenous group living in the State of Pará. The researches are a part of the Project LANGUAGE ASURINÍ DO TOCANTINS: A PILOT PROJECT FOR THE GENERAL METHODOLOGY OF THE SURVEY OF NATIONAL LINGUISTIC DIVERSITY, founded by the MinC/IPHAN under the National Inventory of Linguistic Diversity (INDL). As for Research I, this study adopts the approaches on obsolescent languages (cf. DORIAN, 1981; THOAMASON, 2001a, 2001b; CAMPBEL & MUNTZEL, 1989); Research II follows a survey organized by Maher (2008) and follows his studies about this subject (1996, 2008), whose view is that "verbal repertory and identity are deeply related to the socio-historical context of the individuals" (Dell Hymes, 1984). The aim of the present study is to make a diagnosis of the degree of vitality of the Asuriní do Tocantins language, the Asuriní people sociolinguistic situation and his attitude towards the future of his native language. This work shall contribute to the INDL, which in turn will stimulate language policies in behalf of the life and health of brasilian indian languages and cultures.

Determina la incidencia y factores de riesgo para displasia broncopulmonar (DBP) en recién nacidos (RN) pretérmino de muy bajo peso al nacer del Instituto Nacional Materno Perinatal en el 2009. El estudio es retrospectivo, observacional, de corte longitudinal y analítico (estudio de casos y controles). Se estudió a todos los RN pretérnino de muy bajo peso al nacer a los cuales se les dividió en 2 grupos; Grupo 1 (casos), formado por los RN pretérnino de muy bajo peso al nacer con diagnóstico de DBP. Grupo 2 (control), formado por los RN pretérnino de muy bajo peso al nacer sin DBP. En ambos grupos se buscó la exposición a factores de riesgo prenatales, natales y postnatales. Se elaboró tablas de contingencia para buscar diferencias entre ambos grupos mediante el test de Chi cuadrado con un nivel de significancia de p ≤ 0,05. Posteriormente de calculó el Odds ratio y se efectuó regresión logística. Se estudiaron a 106 RN pretérmino de muy bajo peso al nacer. La DBP estuvo presente en 36 (34%), esta fue más frecuente a menor edad gestacional y menor peso de nacimiento. Los factores de riesgo encontrados fueron: 1) Edad gestacional menor a 28 semanas con OR de 7,7 (IC al 95% 1,2 – 25), 2) Peso de nacimiento menor a 1000 gramos con OR de 4,8 (IC al 95% de: 1,2 – 22), 3) Ventilación mecánica asistida con un OR de 40 (IC al 95% de 6,6 – 140) y 4) Persistencia del conducto arterioso con un OR de 4,6 )IC al 95% de 1,2 – 17,7). Se concluye que la incidencia de DBP en el INMP en el 2009 fue alta y la edad gestacional, peso de nacimiento, la ventilación mecánica y el persistencia del ductus arteriso fueron factores asociados.

Повний текст джерелаPlasma electrolytic oxidation (PEO) or micro-arc oxidation (MAO) is a process through which aluminium oxide layer may be grown onto aluminium substrate. Optical characterization of discharges is carried out using fast video imaging and optical emission spectroscopy, allowing us to distinguish between two different kinds of treatment, depending on the current waveform zand especially on the ratio of positive to negative charge quantity applied to the systeme. The characteristics (morphology, thickness, corrosion resistance) and growth kinetics of the coatings are studied. Growth mechanisms for the different sublayers are proposed for each type of treatment. Electric measurements are carried out allowing us to propose an electric modelling of the system. From these studies, criteria are established that enable coatings with the required properties (in terms of thickness and corrosion resistance) to be grown

Повний текст джерелаBoth experimental and numerical studies have been performed in aIder to highlight the influence of the bubbles density on the drag law. Important results concerning the relative velocity of bubbles in a swarm have been obtained thanks to laser Doppler velocimetry and optical probe measurements in a pure water / air bubble column. Ln particular, it has been shawn that the relative velocity decreases with the local void fraction up to a critical value of 15 % and increases beyond. These evolutions result from a competition between various phenomena, such as turbulence, hindrance and wake acceleration effects. Based on these conclusions, a drag correlation was obtained and tested in a Computational Fluid Dynamics (CFD) code. The significance of the drag law formulation has been demonstrated, especially for the correct description of the transition between the flow regimes of a bubble column and for the accurate prediction of the liquid velocity profiles measured

Повний текст джерелаThe prediction of the macro and microstructures obtained at the end of the solidification is of great interest for the manufacturer of aluminium. In the case of the aluminium DC casting process, phenomena occurring at different scales influence the formation of the macro and microstructures: inoculation, fragmentation of dendrite arms, and growth of the grains at a microscopic scale; motion of the grains and their thermal history at a macroscopic scale. A model of growth and motion of groups of grains has been developed in the frame of the VIRCAST project. This model is simplified with regards to the coupling between the macro and micro scales. The motion and the growth of the grains are calculated using as input data the local heat extraction and the velocity fields computed from a 3D computation of heat, mass and momentum transfers in a DC casting. This model predicts the distribution of grain size, secondary dendrite arm spacing and morphology at the outlet of the casting. Both inoculation and fragmentation phenomena are taken into account

Повний текст джерелаControlling wet granulation process scale-up is still today a challenge due to the lack of tools which could describe quite accurately the mechanisms of granule growth in high shear mixers. The well-known approach consisting in characterizing a mixing process of liquid phases with non-dimensional numbers has therefore been applied to the granular medium in the high shear mixer to establish a correlation between MiPro Pro-C-epT mixers of 3 different scales. In that frame, a method to measure the consistency of the powder has been developed. In addition, the influence of key operating variables on the granule size distributions has been studied by using a D-optimal experimental plan. The results obtained allowed to conclude that phase transitions during granulation appear at constant liquid/powder ratio whatever the scale of the mixer. Finally, the granule growth kinetic has been determined in the small scale mixer and this allowed to characterize the granule growth mechanism in small scale mixer as being mainly driven by a fragmentation-layering process

Повний текст джерелаThe hard acrylic resins synthesis process has been studied. The chemical reaction, initiated by an organic peroxide, is a terpolymerization between styrene, [alpha]-methylstyrene and acrylic acid. The mass or solution polymerization is carried out in a tubular reactor at high temperature (between 200 °C and 260 °C) and with a pressure of 20 bar. Residence times in the reactor are smaller than 5 minutes. The first step of this work has been to define an experimental strategy in order to study the influence of the major operating parameters (residence time and oil temperature). The experimental results will also be used in the elaboration of a tendency model, which objective is to predict the conversions of each monomer and the product properties. The unknown parameters of this model have been identified using the genetic algorithm technique. Then, this model has been adapted for the simulation of the hard acrylic resin industrial production facility

Повний текст джерелаMethionine sulfoxides (MetSO) are easily formed in proteins exposed to reactive oxidative species commonly present in cells. Structural modification and modulation of their activity are the consequence of the oxidation of the protein methionines. Their reduction, back to methionines, is catalyzed by methionine sulfoxide reductases (Msr). These enzymes play a beneficial role in aging process but are involve in the virulence of some bacteria. Msr's are divided in two classes, named MsrA and MsrB, which display opposite stereoselectivities toward the sulfoxide center site. In this PhD thesis, we present studies of the conformational changes of the Neisseria meningitidis MsrB by NMR with the purpose of characterising the catalytic mechanism of the MsrB and of understanding the interaction between MsrB and its partners (MetSO and thioredoxin). From the 1H, 13C and 15N resonance assignments of the reduced from of MsrB, we conclude that the predicted secondary structures are in agreement with those obtained from the X-ray data of the Neisseria gonorrhoeae MsrB. Interaction studies of MsrB with a sulfoxyde substrat show that the active site is not the only one perturbed by the binding. The two next intermediates which are formed along the reaction are a MsrB which possesses a sulfenic acid and a MsrB with a locally specific disulfide bridge. Studies of these two intermediates reveal a structural change during the protein oxidation. Specific interaction between Trx and the oxidized MsrB leads to the reduction of the latter which recovers its starting 3D structure

Повний текст джерелаHealth organizations are complex and in full restructuring. Networks are emergent organizational modes. They are supposed to bring solutions for the necessary reforms by encouraging structures and professionals to work together, to share resources and competences. Their evaluation is both a necessity and an obligation but raises methodological difficulties due to the number and variety of the actors and their interactions. Our study approaches performance evaluation, both global and local, by using modelling as well as functional and dysfunctional analysis FMECA type. We accomplished a modelling of activities and decisions linked, then we analysed obstacles to their functioning in order to put forward proposals for improvement. Obstacles and solutions identified are interdependent. They were incorporated in an organizational decision model. Particularly, our field of investigation concerns a regional oncology network where we studied the process of elaboration, diffusion and use of good practice guidelines

Повний текст джерелаThis work dealt with polypropylene/organically modified montmorillonite (PP/o-MMT) nanocomposites. The main objective was to study the efficiency of using an acrylic acid modified PP (PP-g-AA) as a compatibilizer to promote the intercalation and/or exfoliation of the o-MMT in the PP, on the one hand; and the structures and properties of the resulting composites, on the other hand. Two kinds of PP-g-AA having the same acrylic acid content (6 wt. %) and differing in molar mass were used. The o-MMT content was 0, 1, or 5 wt. % and the PP-g-AA/o-MMT mass ratio was 0:1, 1:1, 2:1 or 5:1. X-ray diffraction and transmission electronic microscopy showed that without PP-g-AA, the structure of the PP/o-MMT was like that of a conventional micro-composite. With PP-g-AA, the o-MMT was intercalated. Compared to the neat PP, the PP/o-MMT showed an increase in thermal stability of up to 40°C and 30% in elastic modulus. However this increase was concomitant to a decrease in impact strength as the compatibilizer/montmorilonite mass ratio increased. Incorporation of the o-MMT in the PP always led to a decrease in CO2 permeability and the degree of decrease was more significant for compatibilized PP/o-MMT composites (better intercalation/exfoliation) reaching up to 50% with respect to the virgin PP. Based on the above results, it was concluded that the PP-g-AA was efficient to promote the intercalation/exfoliation of the o-MMT in the PP. However, there seemed no significant differences between the two PP-g-AA compatibilizers. Overall, for both PP-g-AA, better properties were obtained for higher PP-g-AA/o-MMT mass ratio

Повний текст джерелаSecondary Ion Mass Spectrometry presents many advantages like high sensitivity and excellent mass resolution, but also a major deficiency which is the lack of quantification due to the matrix effect: the ionization probability of secondary ions depends on the sample composition such that quantification is only possible for a known surface composition. To overcome this problem the Cation Mass Spectrometer has been developed in our laboratory. This instrument is equipped with a neutral cesium Cs° evaporator to enable an excellent Cs surface concentration control over the whole range and increase the negative secondary ion ionization probability. In this PhD work, avoiding the matrix effect, respectively increasing the analysis sensitivity are studied by Xy+ bombardment and simultaneous Cs° deposition on different substrates and for various bombardment conditions. In that way the influence of the Cs surface concentration on negative ion formation can be clarified. What's more, useful yield and electron work function variations with respect to Cs surface concentrations allow to discuss the validity of the electron tunneling model and to compare Cs° deposition alone (results from literature) to Cs° deposition with simultaneous ion irradiation (experimental results). The usefulness of the developed technique is shown by several applications

Повний текст джерелаSome very detrimental defects, called white spots, can form during the remelting of Alloy 718. Depleted in alloying elements, they are supposed to be generated by the fall of solid metallic precursors in the liquid pool. In a first step, a model aimed to simulate the remelting process, based on the SOLAR software, has been adapted to the remelting of Alloy 718, then validated by comparison between the simulation results and experimental observations of a remelted ingot. The characterization of electrodes and ingots has shown that large dendrites in the electrode could be the origin of dendritic white spots. This study also determines quantitatively the main characteristics of the three possible sources of discrete white spot precursors (electrode torus, shelf and crown) in terms of structure, composition and size. “Dipping” experiments of synthetic discrete white spots precursors allow a direct measurement of their melting kinetics. These results qualitatively validate a numerical model which describes the melting/solidification process of a spherical particle immerged in a liquid metal bath. Last, the behaviour of a discrete white spot in the liquid pool of a VAR ingot is determined through coupling the phase change model to a calculation of the precursor trajectory. The hydrodynamic and thermal behaviour of the liquid pool is calculated by SOLAR and the characteristics of each of the potential precursor origins are taken into account as input data. The overall model computes, for each origin, a precursor critical size leading to the formation of a white spot

Повний текст джерелаTechnical advising in management of native meadows deal for a long time with the difficulty of stake in work of the generic methods of diagnosis based on the floristic study of plant communities. Time consuming and needing botanical expertise these methods are actually little applied by the farming consultants. An alternative method, based on the identification of dominant plant functional types (TFPs) in the meadow, allows a simple reading and diagnosis of the vegetation without appealing to botanic skills. TFPs can be define response or effect groups of species established according respectively to the response of the species towards gradients of environment factors or to their effect on the productive or environmental functions of the meadow ecosystem. Leaf traits such as Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC) and Leaf Life Span (LLS) have been proposed to identify the growth strategy of species, principally according to their use of soil available nutrients. However, their relation with the agronomic characteristics defining the value of use of the communities has not been studied. The application of this approach to riche species communities requires a preliminary study at the species level. The objective of this work is to asses the relevance of the plant traits (particularly the leaf traits) to classify the species according to their phenology, their nutritive value and their growth. In this purpose, at the INRA research centre of Auzeville, Toulouse mini plots of pure stands of 37 species (21 grasses and 16 dicotyledonous which 3 legumes) were sowed in a 3 replicates split-split plot design in which the species and the level of N availability were respectively the principal and the secondary factors. N treatments were considered as levels of N availability limiting or not limiting the grass growth. Levels of phosphorous, potassium and water were not limiting during the experimental time. Contrarily to SLA and LLS, the LDMC allows separating grasses from the others species. Values of LDMC and SLA vary according to the periods of measures. These same traits and the LLS vary in response to the availability in nitrogen. In spite of the temporal variability and the plasticity of trait values in response to N availability, the rank of the species remained similar for every of three leaf traits characterizing the strategies of growth. These observations were also observed when the analysis was only done on the grass populations. As regards the phenology of the species, the classification established by the LDMC was closer to that established by the flowering stage, the seed ripening stage and principally the start of the stem elongation. The comparative study of grass growth under not limiting conditions confirmed an efficiency of conversion of the radiation significantly higher in species having a resource capture strategy. These species show an earlier development of the leaf area index, higher values of the digestibility of the organic matter, lower contents in fibbers and its components, shorter LLS and an earlier phenology. A discussion on the possibility to extent this specific approach at the level of the community is done. The only knowledge of the LDMC of grasses populations (measured or provided by a traits data-base) inform about the phenology, the growth and the nutritive value of the community an it could be used to asses meadow and grassland value of uses

Повний текст джерелаThe Simulated Moving Bed Process is widely used in many sectors of the chemical, petrochemical, food and pharmaceutical industry. It lies on a chromatographic separation however its continuous character imposed a hybrid behavior, marked by the absence of steady state related to the cyclic switching of the valves and by a narrow operating domain. It results a delicate modeling and a complex and challenging control. In a first part, the manuscript offers a review on chromatography which later leads to modeling and simulation of true and simulated moving beds. Model predictive control is frequently used for multivariable processes and in particular for this type of process. After a general review of model predictive control, this latter is applied on the true and simulated moving beds with consideration of hard constraints for technical parameters of the process like flow rates and soft constraints for economical criteria such as eluent consumption

Повний текст джерелаThe electrocardiogram (ECG) is used in magnetic resonance imaging (MRI) for patient monitoring and for synchronization of the MR images. The environment of MRI (magnetic field, magnetic field gradients and radiofrequency waves) complicates the acquisition of the ECG and needs specific developments. In the first part, the thesis analyses the interferences of the MRI on the ECG and vice versa. This part concludes with a physical model of the interferences between MRI and ECG. Thanks to this model an ECG sensor that is better adapted to the MRI environment has been constructed. In the second part, artefact suppression superposing the ECG signal by software is discussed. A mathematical model is proposed as base for the artefact suppression. The linear and time invariant model (LTI) of the gradient artefact generation is verified and validated. The test methods for the verification of restoration algorithms of the ECG are defined. For offline restoration, the method by FFT, by cross-power spectrum, Wiener filtering and least squares are studied. In the third part, a second category of algorithms is tested in case of online restoration. The LMS and RLS filters and their subtypes are analysed. In the summary, the Wiener filter is used for easier manual annotation of artefacted ECG. The LMS filter as well as a QRS detection and beat classification module are applied to a annotated ECG database in order to show the real-time suppression efficiency of the artefacts due to magnetic field gradient artefacts

Повний текст джерелаA survey carried out on 129 small ruminant farming systems (accounting for 5% of the national livestock) all over the Lebanese territory identified through a cluster analysis five different systems: (i) Zero-Grazing (15 to 95 head flocks of foreign goat breeds), with high inputs; (ii) Sedentary (100-400 head), grazing on communal or private rangelands around the village; (iii) Vertical Transhumance (mainly Baladi goat flocks), moving from low to high altitude depending on season; (iv) Horizontal Transhumance (mixed goat and sheep flocks), moving from 100 to 150 km in the plain; (v) Semi-Nomadic (flocks > 400 head), moving with all their family over 200 to 300 km. Farms sustainability assessment was carried out using a tool built on the IDEA method, which covers agro-ecological, socio-territorial and economical dimensions of sustainability. The multivariate statistical analysis of the 39 indicators showed that systems with diversified potential (presence of animals and plants), specially sedentary and horizontal transhumance, have high scores of sustainability and that economical return was higher in the vertical transhumance and zero-grazing systems in which dairy products are sold directly to the consumers. Improvement of these systems in Lebanon depends on the rehabilitation of rangelands, the improvement of the productivity of the local breeds, and the protection of the typical products on the market through labelling schemes. The history over ten years and the sustainability's trajectory was carried using 60 of these farms. This work typifies farms according to their sustainability and proposes tracks for progress
