In this work are presented results of the experimental study of state selected reactions of H+ and N+(3PJa) ions with molecular hydrogen H2(J = 0, 1) at temperatures in the range 10 - 100 K using 22-pole rf ion trap apparatus. These reactions are important for the formation of interstellar trihydrogen cations and ammonia. To determine the temperature of ions, calibration measurements of the Doppler broadening of spectral lines using N2+ + Ar  Ar+ + N2 laser induced reaction and rate of the ternary association He+ + 2He  He2+ + He were performed. Both ternary and radiative channels of the H+ + H2(J) association reaction were observed at hydrogen number densities in the range 1012 - 1014 cm-3 and 1011 - 1012 cm-3 respectively. Obtained temperature dependences at 11 - 33 K demonstrate substantial role of the H2 rotational energy, results cannot be explained with the existed theories of the stabilization of collisional complexes. Measurements of the rate coefficient of N+(3PJa) + H2(J) reaction at different ortho fractions of H2 show dependence on internal energy of both reactants. State specific rate coefficients of the reaction of nitrogen and hydrogen ions were derived. The adiabatic model and collisional relaxations of N+(3PJa) fine structure levels were considered.

Un évènement Natech est un accident TECHnologique provoqué par l’impact d’un aléa NAturel sur une installation industrielle. Cet accident peut porter atteinte à l’extérieur de l’emprise du site, aux personnes, aux biens ou à l’environnement. L’objectif de ce travail est de mettre au point une méthodologie pour l’analyse et la prévention du risque d’accidents technologiques induits par l’inondation (Natech inondation) d’un site industriel. La méthodologie repose, dans un premier temps, sur une étude des Retours d’Expériences. Il a été identifié que les accidents Natech sont imputables à un rejet de matières dangereuses sur des équipements dits critiques endommagés directement ou indirectement par les eaux d’inondation. Les rejets de matières dangereuses vont amener à trois types d’accidents (incendie, pollution, explosion). Dans un deuxième temps, la méthode MADS-MOSAR a été adaptée à l’application aux accidents Natech inondation. L’analyse a abouti à cinq scénarios génériques d’accident Natech inondation sous forme de cinq nœuds papillons. Une soixantaine de Mesures de Maîtrise de Risque de prévention et de protection ont été identifiées. La validation de la complétude et de la plausibilité des nœuds papillons génériques est effectuée, d’une part, à l’échelle du secteur d’activité de traitement de surface et, d’autre part, à l’échelle spécifique d’établissements industriels. Ce travail a abouti à un outil de diagnostic de la vulnérabilité d’une installation industrielle aux accidents Natech inondation, accompagné d’un catalogue de MMR. Enfin, ce diagnostic a été appliqué sur un site industriel afin d’évaluer son mode opératoire et de l’enrichir par l’expérimentation. / A Natech accident is the impact of a NAtural event on an industrial plant (such as an ICPE- Classified Installation for the Environmental Protection). The impact can trigger a TECHnological accident, damaging the vicinity of the industrial facility (inhabitants, their properties and the environment). The final objective of this work is to develop a risk analysis methodology for the prevention of technological accidents triggered by flooding of industrial facilities. Therefore, the work begins with an analysis of past technological accidents triggered by floods. Thus, it was identified that Natech accidents are the consequences of hazardous materials releases from critical equipment, which in turn are damaged directly and indirectly by flood waters. Depending on the type of hazardous substances released, three categories of technological accidents are observed (fire, pollution and explosion). Afterwards, a risk analysis methodology was developed. It is mainly based on the MADS-MOSAR method, which was modified in order to be adapted to the Natech issue. The analysis resulted in the identification of five generic scenarios of technological accidents triggered by floods that can occur within an industrial installation. These scenarios were represented using the bow-tie tool. Then, around sixty preventive and protective measures were identified. The validation of the elaborated scenarios was done, on one hand, in the surface treatment industrial sector and, on the other hand, in two specific industrial facilities. The validation phase helped to test the completeness and plausibility of the generic scenarios, as well as the relevance of the measures previously identified. Furthermore, the validated scenarios were used to develop a checklist helping operators to decrease the vulnerability of their industrial facilities to technological accidents triggered by floods, along with a catalog of preventive and protective measures. Finally, the tool was applied to an industrial installation in order to enhance it and test its relevance by operators.

Its objective is understand how the militants, in the general frame of their search to revert a lack of institutional political capital, promote the reconversion of UNE symbolic capital, more ample, in political capital, more specific, powerfully the institution in the political arena again. Decurrently of that, I identified a process named patrimonialização da UNE, that is, an action to make the UNE recognized as part of the Brazilian heritage rhetorical. I search to adopt both, a diachronic and sinchronic method. At the first time, was necessary to contemplate the student institution actions were toke place in the UNE building throughout the time to later investigate the ways how this past acts were recouped and used in the present political arena. Firstly the legal acts evolving the building - land were analyzed towards to reconstruct one history to the UNE action in that place. Leave of it, I searched understand the usage of this past by the present agents promoted by the realization of cultural projects and in the process of elaboration and institution of the Law 12.260/2010, which recognize the State responsibility to the acts occurred in the Praia do Flamengo building during the military regime indemnify institution as amend. So, is in the joint of the both camps, the politic and the culture that developed the process which in this work I searched to investigate. / O presente trabalho visa analisar o processo de patrimonialização da União Nacional dos Estudantes, promovido na articulação de memória e reparação, mobilizando elementos do passado da instituição, especialmente os eventos ocorridos no antigo prédio de sua sede, no presente momento conhecido como 'terreno da UNE', na Praia do Flamengo, 132. Tem como objetivo entender como os militantes, no quadro geral de busca por reverter um processo de esvaziamento de capital político da instituição, promovem a reconversão de seu capital simbólico, mais amplo, em capital político, mais específico, potencializando-a novamente no campo político. Decorrente disso se identifica um processo a que foi nomeado patrimonialização da UNE, ou seja, a ação de reconhecê-la como elemento pertencente à retórica do patrimônio cultural brasileiro. Buscou-se adotar uma abordagem diacrônica e sincrônica. No primeiro momento, foi preciso dar conta das ações da entidade estudantil, que tiveram lugar no 'prédio da UNE', ao longo do tempo para, posteriormente, perscrutar as maneiras como estes atos do passado foram recuperados e instrumentalizados no jogo político do presente. Foram analisados, primeiramente, os atos legais que envolveram o prédio/terreno, a fim de reconstruir uma história para a atuação da UNE naquele espaço. A partir desta se procurou entender os usos deste passado pelos agentes do presente, promovidos por meio da realização de projetos culturais e do processo de elaboração e instituição da Lei 12.260/2010, que reconhece a responsabilidade do Estado pelos atos ocorridos no prédio da Praia do Flamengo durante o regime militar e indeniza a instituição como forma de reparação. Assim, é na imbricação dos campos da política e da cultura que se desenvolve o processo que neste trabalho se procurou investigar.

Le présent travail est une petite recherche sur l'apprentissage du français, et plus particulièrement sur l'alternance de l'imparfait et le passé composé parmi des suédophones. Le but du mémoire est de comprendre comment les apprenants appliquent la grammaire malgré la différence entre leur langue maternelle et la langue de l'apprentissage. L'étude part de la différence entre le français et le suédois. Le corpus se compose de dix récits au passé écrits par des étudiants des niveau trois et quatre du système scolaire suédois. Le titre de leur devoir était Un souvenir de mon enfance. Un exercice pris du manuel est aussi analysé. Le résultat montre que d'abord les suédophones apprennent à utiliser les verbes d'état à l'imparfait, puis les suédophones expérimentent avec l'aspect des verbes pour l’alternance entre l’imparfait et le passé composé En conclusion, l'alternance entre l'imparfait et le passé composé est un défi pour les suédophones, mais ce n'est pas un défi insurmontable. / The current piece of research is a study of how second language learners adapt to the distinction between imperfect and perfect in the narrative of past in the French language. The aim of the study is to find out how the learners adopt the grammar despite the difference between their native language and their learning language. The study describes the difference between Swedish and French. The corpus is defined, consisting of ten narratives by ten second language learners on the levels three and four in the Swedish school system. The title was Un souvenir de mon enfance. An exercise in the schoolbook is also analysed. The result shows that the students first learn how to use imperfect in sentences containing a state verb. Later the students attempt the aspect of the verb to practise the shift between the past tense and the perfect tense. In conclusion, the shift between perfect and imperfect is a challenge to the Swedish learner. However, it is not an unbridgeable gap.

The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecl?a Bosi, ?talo Calvino, Jos? Willington Germano, Jos? Maria Can?ado, Lev Vygotsky, Marilena Chau?, Paul Ric?eur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil / Consiste, este trabalho de tese, de uma tradu??o da obra do m?dico brasileiro, Pedro da Silva Nava (1903-1984), em particular, de seus escritos memorial?sticos e das cr?nicas, articulados com os de hist?ria da medicina, objetivando-se defender que as narrativas autobiogr?ficas s?o fontes de pesquisas capazes de promover discuss?es sobre a dilata??o do presente na conflu?ncia de uma sociedade desigual e complexa, em constante processo de mudan?a, como a brasileira. A fundamenta??o te?rica e metodol?gica circula no entorno dos estudos, propostas e teses de Boaventura Santos sobre passado capacitante, subjetividade desestabilizadora, sociologia das aus?ncias, raz?o cosmopolita e trabalho de tradu??o. As bases emp?ricas, extra?das da literatura produzida por Nava, foram analisadas tendo como referentes esta fundamenta??o e estudos que possibilitaram o fluir da tradu??o, entre outros, de Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecl?a Bosi, ?talo Calvino, Jos? Willington Germano, Jos? Maria Can?ado, Lev Vygotsky, Marilena Chau?, Paul Ric?eur e Walter Benjamim, sem descurar daquilo que consideramos imprescind?vel ? pesquisa cient?fica, ? produ??o de conhecimentos prudentes e pertinentes, na perspectiva de uma vida decente. As inflex?es iniciais traduzem o sujeito das Mem?rias e sua educa??o/forma??o, para, em seguida, situar as Mem?rias do sujeito no contexto liter?rio, cient?fico, hist?rico e po?tico brasileiro (1972-2010). Trazem seus principais int?rpretes, discutindo a racionalidade empregada pelo Narrador, que defendemos aproximar-se da cosmopolita, evidenciando a constitui??o de narrativas cujas presen?as inserem-se de antem?o ? verve modernista, vinculada ? matriz discursiva contr?ria ? literatura como espa?o de domina??o, disseminada no Brasil no in?cio do S?culo XX. Desse modo, articula-se ?quela na qual as preocupa??es conformam a constru??o da forma??o social do Brasil, como patrim?nio nacional, atrav?s da narrativa liter?ria com enfoque em um princ?pio hist?rico que torna o passado capacitante. Permite, assim, sua releitura, para cujas tramas convergem ? mem?ria, os modos de vida, a pluralidade da linguagem e da cultura brasileira, formada por v?rios povos, confluindo para uma concep??o, n?o de cultura, mas de multiculturalidade brasileira. A quest?o da mem?ria foi tratada no espa?otempo das experi?ncias do ser que narra, moldado por uma subjetividade desestabilizadora que buscou ordenar os testemunhos de um tempo, de uma hist?ria e de uma sociedade, recontando-os pela imagina??o criadora, quase ficcional, para fazer circular seus conhecimentos sobre o Brasil, unidos aos seus conhecimentos m?dicos, bem como aos de outros sujeitos de seu grupo de conviv?ncia e de outros grupos com os quais manteve contato. Assim, retratou bens culturais materiais e imateriais do pa?s como forma de preserva??o, atribuindo-lhes significados e sentidos. Aproxima-se, portanto, da perspectiva de sociologia das aus?ncias, pela dilata??o do presente e pelas l?gicas a ela inerentes em suas narrativas de si e do Brasil

Results of water bug sampling ascertained by selected sampling methods (net trapping and different water light traps) were compared in this thesis. Selected ecological characteristic of taxocen, based on data gained by these methods, are calculated and compared. The water light trap with heterochromatic LEDs (white LEDs respectively) was found the most forceable method for sampling of both water bug species and their specimens.
