Nos espa?os extraescolares podem ser descobertos in?meros mundos musicais e estes nos propiciam uma rica variedade de rela??es de ensino-aprendizagem sem a obrigatoriedade da presen?a do professor nesse processo, j? que, segundo Petitat (2011) ?a educa??o deriva da inser??o em rela??es ? ?s vezes escolares, mas, a maior parte do tempo, n?o escolares?. A Comunidade Cat?lica Shalom n?o tem por finalidade promover a aprendizagem musical, por?m, a rela??o estreita que seus membros t?m com a m?sica ? ineg?vel. A m?sica est? no centro da espiritualidade Shalom, presente no cotidiano e nas atividades que a Comunidade realiza (celebra??o eucar?stica, reuni?es dos grupos de ora??o, eventos). Em todas estas atividades realizadas pelo Shalom s?o atribu?das ? m?sica variadas fun??es e diversos usos. A presente obra tem como objetivo identificar as poss?veis rela??es de ensino-aprendizagem e transmiss?o musical nesse ambiente extraescolar. Para alcan?ar tal objetivo, fa?o uso da etnografia da m?sica, buscando, atrav?s da observa??o e coleta de dados, descrever as maneiras como as pessoas fazem a ?m?sica do Shalom?. / The academic route helped me to comprehend that school spaces are not the only spaces that provide music education. In the out-of-school spaces, many musical worlds can be discovered and these offer us a rich variety of teaching-learning relationships without the presence of the teacher in this process, since according to Petitat (2011) ?education derives from insertion in relations ? sometimes at schooling, but most of the time, not schooling?. The Shalom Catholic Community is not intended to promote musical learning, but the close relationship its members have with music is undeniable. Music is at the heart of Shalom spirituality, present in daily life and in the activities that the Community performs (Eucharistic celebration, prayer group meetings and events). In all these activities performed by the Shalom are assigned to the music varied functions and various uses. The present work aims to identify possible teaching-learning relationships and musical transmission in this out-of-school environment. To achieve this goal, I make use of the ethnography of music, seeking, through observation and data collection, to describe the ways in which people make "Shalom music".

Le groupe de Cremona de rang 2 est le groupe des transformations birationnelles du plan projectif. Le but de cette thèse est d'étudier et de construire des espaces hyperboliques sur lesquels le groupe de Cremona agit et qui permettent de mettre en œuvre des méthodes provenant de la théorie géométrique des groupes. Il est connu depuis une dizaine d'année que le groupe de Cremona agit sur un espace hyperbolique H analogue au plan hyperbolique classique mais de dimension infinie. Dans un premier temps, nous montrons que le groupe de Cremona défini sur un corps quelconque n'est pas simple en le faisant agir sur cet espace hyperbolique. Ceci prolonge un résultat déjà connu dans le cas d'un corps de base algébriquement clos. Nous nous intéressons ensuite à un graphe construit par D. Wright sur lequel agit le groupe de Cremona. Nous montrons qu'il ne possède pas la propriété que nous souhaitions, à savoir qu'il n'est pas hyperbolique au sens de Gromov. Nous construisons également un domaine fondamental pour l'action du groupe de Cremona sur H via la méthode des cellules de Voronoï. Nous caractérisons les applications du groupe de Cremona qui correspondent à un domaine adjacent au domaine fondamental. Cela nous permet de prouver que le graphe de Wright est quasi-isométrique au graphe dual à ce pavage. Nous obtenons ainsi une manière de retrouver le graphe de Wright dans H. Nous montrons enfin qu'en modifiant ce graphe dual, nous obtenons un graphe hyperbolique au sens de Gromov. Dans une dernière partie, nous nous intéressons à une autre propriété naturelle qui est la propriété CAT(0). Nous construisons un complexe cubique CAT(0) de dimension infinie muni d'une action naturelle du groupe de Cremona. / The Cremona group of rank 2 is the group of birational transformations of the projective plane. The aim of this thesis is to study and build some hyperbolic spaces with a natural action of the Cremona group. We want these spaces to have good geometric properties in order to use methods coming from geometric group theory. It is known that the Cremona group acts on a hyperbolic space H which is similiar to the classical hyperbolic plane but in infinite dimension. First, using this action, we show that the Cremona group is not simple over any field. This extends previous results over an algrebraic closed field. Then we study the Wrigth's graph. We show that it doesn't have the property we are looking for, in the sense that it is not Gromov hyperbolic. We build a fundamental domain for the action of the Cremona group on H 8 via Voronoï's cells. We characterize birational tranformations that correspond to adjacent domains of the fundamental domain. This allows us to prove that the Wright's graph is quasi-isometric to the dual graph of this tessellation. It's give us a way of realizing the Wright's graph inside H. Finally, we show that by modifying the dual graph we obtain a Gromov hyperbolic graph. In the last part, we are interested in another classical property which is the CAT(0) property. We build an infinite dimensional CAT(0) cubical complex which comes with a natural action of the Cremona group.

L'objet de cette thèse est l'étude de revêtements ramifiés V' to V de variétés hyperboliques compactes V cubiques, c'est-à-dire dont le groupe fondamental pi_1(V) opère proprement et cocompactement sur un complexe cubique CAT(0). Notre première approche consiste à construire un complexe cubique localement CAT(0) comme revêtement ramifié du complexe obtenu par cubulation de V. La difficulté est alors de vérifier que ce complexe a le même groupe fondamental que V’. On réalise ce programme dans le cas ou V’ est une « variété de Gromov-Thurston ». Notre seconde approche concerne plus généralement le cas où le lieu de ramification du revêtement V' to V est contenu dans une sous-variété convexe de codimension 1. La préimage de cette variété dans V’ puis dans le revêtement universel X’ de V’ fournit un système naturel de « murs ». La difficulté consiste alors à montrer que ces murs séparent linéairement X’ afin d'utiliser les théorèmes classiques de cubulation. / The goal of this thesis is to study of branched covers V' to V of closed hyperbolic manifolds that can be cubulated, i.e. Whose fundamental group pi_1(V) acts properly and cocompactly on a CAT(0) cube complex. We give sufficient conditions for pi_1(V') to be cubic as well.We tackle this question in two different ways. In a first approach we build a negatively curved cubical complex as a ramified cover of a cubical complex obtained by cubulating V. Then the main issue is to check that the fundamental group of this complexe is isomorphic to the fundamental group of V'. We manage to do so when V' is so called “Gromov-Thurston manifold “. Our second approach deals with the more general case where the branched locus of V' to V is contained in a codimension 1 convex submanifold. The preimage of this submanifold on V' and on the universal cover X' of V' provides a natural system of “walls”. Then the main issue is to show that these walls linearly separate X'. This enables us to use classical cubulation theorems.

Under det närmaste seklet kommer Sverige att vara med om en klimatförändring med en ökad nederbörd upp mot 40 % i delar av landet. Översvämningar kommer bli vanligare och kraftigare skyfall under kortare perioder är det största hotet mot ett fungerande avrinningssystem. De mängder dagvatten som ska hanteras i stadsbebyggelse kan vara mycket stora på grund av att grönytor har bytts ut mot hårdgjorda ytor.   SWMM-CAT (Storm Water Management Model – Climate Adjustment Tool) är ett program som kan skapa prognoser för framtida klimatförändringar. Genom att söka på koordinater eller postnummer i USA kan användaren få fram data för förändring i nederbörd, avdunstning, temperatur och största dygnsnederbörd vid olika återkomsttider vid just den platsen sökningen skett i. Informationen kan användas för att få en uppfattning i hur dessa parametrar kommer att ändras i framtiden. Informationen kan även sparas till SWMM (Storm Water Management Model) i form av klimatjusteringsfaktorer. SWMM är ett simuleringsprogram som används för planering och analys av dagvattenavrinning. Med hjälp av dessa klimatjusteringsfaktorer kan man vid projektering av avloppssystem vara mer förberedd och dimensionera med hänsyn till det framtida klimatet.   Genom uppbyggnad av en modell i SWMM har vi jämfört resultatet av en simulering utan klimatjusteringar och en simulering med klimatjusteringar. Resultatet visar att vattenflödet från avrinningsområdet skulle öka från 43 l/s till 66 l/s. Utifrån denna flödesökning ser vi att det finns en stor vikt att beakta hur klimatförändringarna kan komma att påverka dessa flöden vid dimensionering av avloppssystem.   SWMM-CAT är ett lätthanterligt och användarvänligt program som enkelt kan användas för att få en inblick i hur klimatförändringarna kan komma att påverka temperatur och nederbörd. Det krävs dock erfarenhet av SWMM för att göra korrekta simulationer med justeringsfaktorer från SWMM-CAT. Eftersom klimatförhållanden skiljer sig geografiskt går SWMM-CAT inte att tillämpa i Sverige då prognoserna är framtagna över ett rutnätssystem i USA. Med hjälp av forskning från Rossby Centre är det möjligt att ta fram data för framtida förändringar i nederbörd, avdunstning och temperatur för Sverige.  Det tror vi är tillräckligt med underlag för att skapa ett program liknande SWMM-CAT i Sverige.   För att på bästa sätt möta klimatförändringarna i svenska stadsmiljöer påstår vi att man bör kombinera klimatprognoser med mer öppen dagvattenhantering. / Sweden will during this century experience an increased amount of precipitation, up to 40 % in some parts of the country.  Flooding will be more common and heavy rain during short periods of time is the greatest threat of having a functioning drainage system. The amount of storm water that urban areas will have to handle can be massive due to the lack of infiltration areas.   SWMM-CAT (Storm Water Management Model – Climate Adjustment Tool) is software that can create future climate change projections. By searching for coordinates or zip-codes in the US the user can receive data for changes in precipitation, evaporation, temperature and 24-hour design storm at a specific location. The information can be used to get more knowledge of how these parameters will change in the future, but also to import as adjustment factors to SWMM (Storm Water Management Model). SWMM is a simulation software for planning and analysis of storm water runoff. The adjustment factors allow planning of sewer systems with consideration of future climate change.   To compare the results of a simulation with SWMM-CAT and without SWMM-CAT we constructed a SWMM-model. The result showed an increased water flow from the sub catchment area from 43 l/s to 66 l/s. This result displays that it is important to consider how the climate change can affect the sizing of sewer systems.   SWMM-CAT is a user friendly software and can easily be used to predict future climate change outcomes related to precipitation and temperature, but it demands experience from SWMM to make correct simulations with adjustments from SWMM-CAT. Since climate changes varies geographically, SWMM-CAT cannot be used in Sweden because the projections is based on a grid system over the US. The research of Rossby Centre provides future climate change projections in precipitation, evaporation and temperature for Sweden. We believe that it is sufficient data to create a software similar to SWMM-CAT in Sweden.   We believe that the best way to cope with the climate changes in urban areas is to combine future climate projections with low-impact development.

Among the protected area system of Vietnam, Cat Ba appears as an ideal national park for biodiversity research and conservation. It covers a large area of karst landscape including islands and different ecosystems ranging from forests, wetland, mangroves, caves and others. Since the establishment of Cat Ba National Park in 1986, biodiversity research and conservation within the park have been strongly promoted and raised. The park has been well known as home to highly diverse flora and fauna with many species endemic to the archipelago and Vietnam. A series of projects and programmes have been effectively implemented for urgent and long-term conservation of threatened species. However, results from scientific research also indicated that many sites and species are still almost unstudied while several sections of the park’s buffer zone are affected by human activities including unscientific development of ecotourism. We recently conduct a field survey and recorded 2 bat species and echolocation calls in their natural habitats. This paper provides an overview of achievements with recent records and recommendations for strengthening conservation of biodiversity and habitats in the park and surroundings. / Trong hệ thống khu vực bảo vệ của Việt Nam, Cát Bà là một vườn quốc gia có điều kiện thuận lợi đối với công tác nghiên cứu và bảo tồn đa dạng sinh học. Vườn quốc gia này bao gồm diện tích lớn cảnh quan núi đá vôi với các đảo và hệ sinh thái đặc trưng như rừng trên núi, đất ngập nước, rừng ngập mặn, hang động và nhiều hệ sinh thái khác. Từ khi thành lập Vườn Quốc gia Cát Bà năm 1986, công tác nghiên cứu và bảo tồn đa dạng sinh học được quan tâm và thực hiện ngày càng nhiều. Vườn quốc gia cũng chứa đựng khu hệ động vật và thực vật đa dạng với nhiều loài đặc hữu cho quần đảo và Việt Nam. Nhiều dự án và chương trình đã được thực hiện nhằm bảo tồn cấp bách và lâu dài những loài bị đe dọa. Tuy nhiên, những kết quả nghiên cứu khoa học cũng cho thấy nhiều khu vực trong phạm vi vườn quốc gia gần như chưa được nghiên cứu trong khi một số tiểu khu thuộc vùng đệm đang bị ảnh hưởng bởi hoạt động của con người như sự phát triển du lịch. Chúng tôi đã ghi nhận được 2 loài dơi cùng với tiếng kêu siêu âm trong môi trường sống tự nhiên của chúng qua thời gian điều tra thực địa vừa qua. Bài báo này cung cấp dẫn liệu tổng quan và cập nhật về những kết quả đã đạt được với những thông tin cập nhật và đề xuất nhằm thúc đẩy công tác bảo tồn đa dạng sinh học và sinh cảnh ở vườn quốc gia và vùng phụ cận trong tương lai.

The Catholic Schools of Porto Alegre Archdiocese by their principals was the research field to this study. Conserning the principals profile was considered, in this study, the principals professional and academical development at the time before and during the period in which it plays a role in a respective school. The relationship between the principal education process with the quality of education opens the possibility for the articulation of three themes: school management, with focus on managers education; quality of education; and the identity of the Catholic school. This study follows the qualitative methodology, the instruments for data collection used were personal interviews and through an online survey, data analysis was performed from data obtained in interviews and in continuity with the literature search. This research aims to identify the important aspects about the training of school managers and, specifically, the managers of the Catholic school and further analysis on the possible relationship between the management and the quality of education in order to emphasize the values inherent to the identity and Catholic mission school in Brazil. Thus, on the results, it was found that the confessional identity and tradition of the school is the integrating factor between the management model, the manager profile and quality of education. / Neste estudo busca-se relacionar o processo de forma??o do gestor da escola cat?lica com a qualidade da educa??o. As escolas cat?licas, na Arquidiocese de Porto Alegre, no estado do Rio Grande do Sul, por meio de seus gestores serviram de campo de investiga??o. Quanto ao processo de forma??o dos gestores foi considerada a trajet?ria profissional e acad?mica constru?da pelo gestor antes e durante o per?odo em que desempenha a fun??o diretiva na escola. Neste estudo, o processo de forma??o do gestor da escola cat?lica, em sua rela??o com a qualidade da educa??o, abre possibilidades para a articula??o entre tr?s eixos tem?ticos: a gest?o escolar, no vi?s da forma??o de seus gestores; a qualidade da educa??o; e a identidade da escola cat?lica. Utilizou-se a metodologia qualitativa e os instrumentos de coleta de dados utilizados foram as entrevistas presenciais e via question?rio online. A an?lise dos dados foi realizada a partir dos dados obtidos nas entrevistas e em continuidade com a pesquisa bibliogr?fica. Nesta pesquisa teve-se por objetivo identificar os aspectos importantes sobre a forma??o de gestores de escola e, em espec?fico, de gestores da escola cat?lica e aprofundar a an?lise sobre a poss?vel rela??o entre a gest?o e a qualidade da educa??o de modo a ressaltar os valores inerentes ? identidade e miss?o da escola cat?lica no Brasil. Assim, nos resultados, constatou-se que a identidade confessional e a tradi??o da escola ? o fator integrador entre o modelo de gest?o, o perfil do gestor e a qualidade da educa??o.

Nevertheless, pesticides can persist in the environment and be harmful to non target organisms. Mesotrione, the active ingredient of Callisto, is a selective herbicide recommended for pre and post-emergent weed control in corn culture, with high leaching potential, and it has the ability to inhibit the activity of HPPD enzyme, interfering with the synthesis of carotenoids in target plants. The aim of this work was to evaluate the strategies used by the strain Bacillus megaterium Mes13 to avoid toxic effects of Callisto and its active substance, mesotrione, by analyzing the differential expression of antioxidative enzymes, mesotrione degradation, and changes in membrane structure. There were no specific responses from isozymes to herbicides. Catalase activity at Callisto treatment was lower than control, suggestingother mechanisms affecting cellular defense. Lipid peroxidation (MDA), which depends on saturation degree of membrane fatty acids, was lower at Callisto treatment, and changes in bacterial membrane were observed at Callisto treatment, probably protecting membrane against lipid peroxidation. Mesotrione was used neither as C nor N source for growing of Bacillus megaterium, although degradation of mesotrione was higher at minimal medium with no N source, suggesting that herbicide degradation occurs as a cometabolism. Probably the membrane modifications and mesotrione degradation made this bacteria able to tolerate the herbicides at experimental conditions. / O uso de agroquímicos se faz necessário para aumentar a produtividade e suprir a crescente demanda por alimentos. Entretanto, estes químicos podem persistir no meio ambiente e serem danosos aos organismos não-alvo. O mesotrione é um herbicida seletivo indicado para o controle pré e pós-emergente de plantas daninhas na cultura do milho com alto potencial de lixiviação, que apresenta a capacidade de inibir a atividade da enzima 4-hidroxifenil-piruvato-dioxigenase (HPPD), interferindo na síntese de carotenóides. Neste trabalho analisamos três possíveis estratégias utilizadas pela linhagem Bacillus megaterium Mes13 para tolerar o herbicida Callisto e seu princípio ativo, mesotrione: expressão de enzimas antioxidativas, degradação do princípio ativo e modificações na estrutura de lipídeos da célula. Avaliações de atividade e perfil proteico de catalase (CAT) e superóxido dismutase (SOD) foram realizadas para avaliar os possíveis danos gerados pelo contato da bactéria com o herbicida. Nenhuma isoforma específica foi observada em resposta aos tratamentos contendo os xenobióticos e a atividade de CAT foi mais baixa no tratamento contendo Callisto indicando outros possíveis mecanismos de defesa celular. Corroborando estes resultados, as análises de peroxidação lipídica (MDA), que dependem do estado de saturação de lipídeos de membrana, mostraram taxas mais baixas no tratamento com Callisto. Modificações na membrana bacteriana foram observadas nos tratamentos contendo Callisto, o que, possivelmente diminuíram as taxas de peroxidação lipídica. Esta linhagem não utiliza mesotrione como fonte de nitrogênio e carbono, contudo, o processo de degradação do herbicida foi mais eficiente na ausência de Nitrato de Sódio em meio de cultura. A degradação provavelmente se dá por uma enzima inespecífica. Na ausência da fonte primária de nitrogênio, esta linhagem degrada o mesotrione por cometabolismo. Provavelmente as modificações na membrana plasmática aliada a degradação da molécula do xenobiótico conferiram a linhagem capacidade de tolerar a presença dos herbicidas nas condições experimentais testadas. Palavras-chave: SOD, CAT, MDA, Biodegradação de herbicidas, Fonte de nitrogênio, modificações na membrana plasmática.

Este trabalho trata de ambientes de software para a realização de teste e caracterização de dispositivos, componentes ou circuitos eletro-eletrônicos, de forma automatizada. Ênfase especial é dada à problemática relacionada ao teste e caracterização automatizados de dispositivos e circuitos integrados. O assunto é tratado sob dois pontos de vista distintos e complementares: i) Sob o ponto de vista do engenheiro de teste e caracterização, que realiza experimentos físicos, que são as medidas e aquisições de dados, processa, visualiza e analisa dados. ii) Sob o ponto de vista do projetista de ferramentas de software, que desenvolve programas de computador para automatizar as tarefas rotineiramente realizadas durante o teste e a caracterização. Após a analise do assunto em questão, um ambiente de software (Framework), chamado SGC, é proposto e implementado. O SGC foi implementado em ambiente MS-WindowsTM através de um paradigma de orientação a objetos, e pretende atender as necessidades inerentes ao teste e caracterização automatizados, quando tratados sob os dois pontos de vista citados. O ambiente SGC é um sistema aberto, a fim de permitir o fácil acoplamento de novas facilidades, bem como mostra-se um sistema prático para suportar rotinas de teste e caracterização em laboratório. / This work deals with software environments for automatic test and characterization of electro-electronical devices, components and circuits. Special attention is paid to the features of testing and characterizing integrated devices and circuits. The subject is treated in two different and complementary views: i) The needs of the test and characterization engineer are addressed. The test engineer carries out physical experiments, which embody measurements and data acquisitions, data processing, visualization and analysis. ii) The needs of the software tools developer, who develops computer programs for the automation of the procedures that are usually carried out during test and characterization, are also addressed. After the analysis of the subject under study, a software framework, called SGC ("Sistema de Gerenciamento e Controle"), is proposed and implemented. The SGC Framework was implemented under MS-WindowsTm using a object oriented approach. The SGC framework aims to fulfill the needs inherent to the automatic test and characterization, when treated using the approaches mentioned above. The SGC Framework is a open system, supporting the easy integration of new software functions to the environment, as well as a practical system for test and characterization laboratory routines.
