COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
Passados, Presentes e Presenças: A Simultaneidade Histórica em Hans Ulrich Gumbrecht. Tomando o experimento historiográfico, Em 1926: Vivendo no Limite do Tempo de Hans U. Gumbrecht como ponto de partida, visa-se aqui investigar certos aspectos centrais nos estudos teóricos de literatura atuais. É com um inusitado Manual do Usuário que Gumbrecht inaugura sua indagação acerca das possibilidades de um texto (vs. uma miríade de recursos midiáticos disponíveis) simular no leitor o efeito de imediação completa. Compartilhando deste desejo de formulação de uma história sensível - onde presença está como outro do sentido - pretende-se encaminhar uma discussão acerca da proposta de produção de presença - vinculada a seu projeto de materialidade nos processos comunicativos, artísticos e literários. Propõe-se discutir implicações teóricas do experimento de Gumbrecht contrapostas a outros modelos inovadores de representação do passado, tais como os discutidos por expoentes da escola dos Annales - em particular, Michel de Certeau, François Furet e Paul Veyne. Segundo Gumbrecht, a simulação de imediação reduziria a ênfase sobre a prática hermenêutica do conhecimento do passado. Portanto, neste palco sem atores parece imperar a materialidade dos elementos envolvidos nos processos comunicativos. Neste âmbito cabe perguntar: seria plausível a teorização acerca destas novas formas comunicativo-literárias - que em toda a sua inegável virtualidade não deixam de acentuar afetos e sensibilidades, minimizando (sem excluí-las) formas de racionalização?
Pasts, Presents and Presences: Historical Simultaneity in Hans Ulrich Gumbrecht. Taking Hans U. Gumbrecht´s In 1926: Living on the Edge of Time as a starting point, it is the purpose of this study to explore and scrutinize certain specific aspects and unresolved questions present in current Literary Studies. The somewhat whimsical User´s Manual is indicative of the experimental nature of his project. The central question will fall upon the capabilities of a written book (as opposed to other media) to produce or, rather, to re- produce past experiences-you should feel in 1926. Seeking, then, the effect of (almost) perfect immediacy, Gumbrecht hopes to help formulate or contribute to what could be classified as Sensorial Historiography - wherein the act of generating presence is to be understood as opposed to Hermeneutics. Sharing his impulse to evoke past worlds, this paper intends to develop a thorough discussion centered upon Gumbrecht´s own notion of production of presence. Inevitably, this includes a short analysis of his theories on the materialities of communication. In addition, the essay will also attempt to draw connections and parallels between his notions of historiography and those of the Annales school in France - i.e. Michel de Certeau, François Furet and Paul Veyne who, in their new proposals of historiography, offer interesting counterpoints to the non- hermeneutical model. Therefore, the question which will guide and orient the course of this study will be: would it be plausible and relevant to theorize about these new (and very experimental) forms of representation, which seem to privilege affections and sensibilities over more rational approaches - albeit without excluding them entirely?

Writing about redress 1 -un-dressed, giving my voice to the work, is probably the hardest part for me. It was my voice which was silenced when, as an eleven year old, I stepped into the witness box of the Cape Town Magistrates' Court. In the end my only defence was silence, as each consecutive question of the defence distorted my personal story until my position of victim turned into that of perpetrator. That is to say, the perpetrator was released and I went to jail. Not literally. But the effect of the trauma shaped who I am today. This experience triggered my ongoing investigation of systems of control, positions of power and causes of trauma which I explored in my undergraduate year in 2007. Comfort Room - ukhuselekile - Speak out 1 was a psychologically charged installation which explored aspects of secondary trauma experienced by children in the judicial process. The current body of work moves beyond the trauma as it investigates processes of redress. For that reason the details of the initial events are no longer the primary concern; strategies of transformation are at the heart of this investigation. This brief detour outlines my personal motivation and interest in these strategies, or forms of redress, which lead me to juxtapose processes of what I have termed aesthetic redress against processes of judicial redress. I therefore stage the fictional case of R v Judicial Redress 2010 (R v JR 2010) 2 in this document and my practical body of work.

Calle Strand: Brian Wilson presents Smile! – a study of the circumstances surrounding theabandonment of Smile - Uppsala University, Department of Musicology, C-essay. This essay is about the course of events that led to the abandonment of the Beach Boys albumSmile in 1967. The purpose of the essay is to differentiate the medial assumption of why Smilewas never released and also investigate to what extent media have influenced this assumption.The medial assumption is compared to actual events of the time of the abandonment andthe difference is then being discussed in a media-theoretical perspective.The theoretical framework is based on theories by Denis McQuail. His ideas aboutmedia's influences on the reception of its audience are of great importance for the essay andthe notions of agenga-setting and framing has a central role.Finally the conclusion is drawn that the medial assumption is a simplified and distortedexplanation to why Smile was never released. The actual events discover several alternativereasons, but media choose to focus on the assumption that gain them the most (they set theagenda and frame the information to their advantage) and present it as the only reason to theabandonment of Smile.

Streszczenie:

Scholarship on Post-Apartheid South African literature has engaged in various ways with the politics of identity, but its dominant mode has been to understand the literature through an anxious rupture-continuation paradigm in which the Apartheid past manifests itself in the present. However, in the contemporary moment, there are writers whose texts attempt to forge new paths in their depictions of identities both individual and collective. These texts are useful in contemplating how South Africans experience belonging and dislocation in various contexts. In this thesis, I consider a range of contemporary South African texts via the figure of lifewriting. My analysis demonstrates that, while many texts in the contemporary moment have displayed new and more complex registers of perception concerning the issue of ‘race’, there is a need for more expansive and fluid conceptions of crafting identity, as regards the politics of space and how this intersects with issues of belonging and identity. That is, much South African literature still continues along familiar trajectories of meaning, ones which are not well-equipped to understand issues that bedevil the country at this particular historical moment, which are grounded in the political compromises that came to pass during the ‘time of transition’. These issues include the recent spate of xenophobia attacks, which have yet to be comprehensively and critically analysed in the critical domain, despite the work of theorists such as David Coplan. Such events indicate the need for more layered and intricate understandings of how our national identity is structured: Who may belong? Who is excluded? In what situations? This thesis engages with these questions in order to determine how systems of power are constructed, reified, mediated, reproduced and/or resisted in the country’s literature. To do this, I perform an attentive reading of the mosaic image of South African culture that emerges through a selection of contemporary works of literature. The texts I have selected are notable for the ways in which they engage with the epistemic protocol of coming to know the Other and the self through the lens of the Apartheid past. That engagement may take the form of a reassertion, reclamation, displacement, or complication of selfhood. Given that South African identities are overinscribed in paradigms in which the Apartheid past is primary, what potentials and limits are presently encountered when writing of the self/selves is attempted? My study goes beyond simply asserting that not all groups have equal access to representation. Rather, I demonstrate that the linear shaping of the South African culture of letters imposes certain restrictions on who may work within it. Here, the politics of publishing and the increasing focus on urban spaces, such that other spaces become marginalized in ways that reflect the proclivities of the reading public, are subjected to close scrutiny. Overall, my thesis aims to promote a rethinking of South African culture, and how that culture is represented in, and defined through, our literature.

Christmas is generally described as cultural, ritual and sociological phenomena of devotion, community and consumption. The topic of this dissertation concerns a specific stream of research within the general domain of consumer behaviour. The focal objective of this study is to develop a model and generate theory about parental gift giving behaviour at Christmas. My study is unique because it attempts to model parental gift giving at Christmas in a consumer behaviour context. Consumer behaviour theory suggests that parents seek information about possible gifts, set selection criteria for gift purchase, evaluate alternatives and buy the gifts for their children. Following this broad view of theory, parents respond to children's request behaviour, evaluate the suitability of any requests and purchase the approved or appropriate items as Christmas gifts. Children are encouraged to request any gifts that they desire, and these gift requests are often for specific brands. In general Christmas gifts are selected from children's products and brands and there is extensive debate and research relating to television advertising and children's request behaviour at Christmas. However, parents are not exposed to the same sources of advertising as their children and there is little evidence of research into the very important topics concerning motives, strategies, evaluations and the giving of brands that characterize parents' Christmas gift giving to their children. The significance of this dissertation resides in the development and presentation of a comprehensive model for the conceptualisation of parental gift giving at Christmas, based on antecedents to parents' social roles of gift giving and direct and indirect behavioural outcomes of those gift giving roles. Measures for each of these outcomes are developed and gender effects are also explored. The sample frame was described as a parent with at least one child between the ages of 3-8 years and a survey package was delivered to parents of children from participating schools and kindergartens. There were 2560 surveys distributed, with 450 individual responses representing a return rate of 17.6%. The 450 cases available for analysis were factor analysed and formed into composite and latent variables to facilitate statistical analysis via Partial Least Squares (PLS) regression, which is an appropriate procedure when the relationships are unknown or theoretical. The results of the research have two distinct streams. The first stream relates to the creation and validation of measurement constructs for the concept of Christmas spirit, parental gift giving, request communication, brand benefits and use of information sources, as well as involvement in giving gifts and involvement in giving brands as gifts. The second stream relates to the relationships between variables; the results support the relationships antecedent to the parents' social roles of gift giving. There is a significant relationship of Christmas spirit with involvement in giving gifts and with parental gift giving roles. A significant relationship also exists between involvement in giving gifts and parental gift giving roles. However, there is limited support for propositions related to outcomes of parental gift giving roles where there are significant relations between these roles and Christmas request communication, brand benefits and information sources. There is also a significant, indirect relationship between brand benefits and involvement in giving brands as gifts. As part of the second stream, gender differences were examined; the results show that mothers' Christmas spirit has no effect on their gift giving roles and gift giving roles have no significant effect on request communication and information source usage. On the other hand, the results show that the fathers' gift giving activities reflect the relationships outlined in the parental model. The study has academic implications for sociology and consumer behaviour disciplines and commercial implications for manufacturers, advertisers, brand owners and retailers. Further investigations will be necessary to incorporate other elements into the parental gift-giving model and to extend the theory toward a fuller understanding of the parental Christmas gift giving phenomena.

Streszczenie:

Les ressources en eau sont menacées par diverses formes de pollution et les procédés de traitement proposés sont souvent complexes avec des résultats qui ne sont pas toujours satisfaisants. Cette étude vise à développer un traitement, simple et peu coûteux pour réduire au maximum la présence dans l’eau des acides humiques (AH), un polluant organique. L’approche adoptée est la mise en place d’un procédé hybride combinant l’adsorption et la photocatalyse hétérogène réalisée avec le dioxyde de titane. La méthode d’adsorption a été réalisée d’une part avec du charbon actif et d’autre part avec trois argiles provenant de la Côte d’Ivoire. Le charbon actif a été préparé à partir des coques de coco selon une procédure assez simplifiée, sans additifs chimiques, dans le souci d’obtenir un adsorbant économique et écologique. Les trois argiles brutes (Dabou, Yamoussoukro et Katiola) ont chacune subi des opérations de purification pour obtenir des fractions pures. Des tests de caractérisation réalisés par diverses techniques (analyse élémentaire, DRX, adsorption d’azote, IR, etc.) ont été effectués sur les adsorbants obtenus. Les essais d’adsorption réalisés avec le charbon ont montré qu’aucune élimination des AH n’a été observé. La raison principale serait le manque de groupements fonctionnels sur la surface du charbon préparé. Les tests d’adsorption conduit avec les argiles ont montré que ces matériaux sont capables d’éliminer les AH. Les résultats ont révélé que l’argile la plus riche en kaolinite (celle de Yamoussoukro) a une capacité d’adsorption maximale largement supérieure (115 mg/g) par rapport aux autres (20 et 15 mg/g pour Dabou et Katiola respectivement). Cette différence trouve son explication dans la composition minéralogique et structurale de chacune des argiles. Les tests de photocatalyse menés ont montré une dégradation des macromolécules d’AH en des composés de plus petites tailles. La minéralisation de la matière organique a été observée avec une réduction du carbone organique total de l’ordre de 72 et 82 % respectivement aux pH 7 et 3. En mettant en série à pH 3, les deux procédés à savoir l’adsorption suivie de la photocatalyse, une réduction de 95% du carbone organique total des AH est obtenue. Le procédé hybride ainsi réalisé montre un avantage certain car il permet d’éliminer la quasi-totalité de la pollution organique initiale
Water resources are threatened by various forms of pollution and the proposed treatment processes are often complex with results that are not always satisfactory. This study aims to develop a simple and inexpensive treatment to minimize the presence of humic acids (HA), an organic pollutant, in water. The approach adopted is the establishment of a hybrid process combining adsorption and heterogeneous photocatalysis performed with titanium dioxide. The adsorption method was carried out primary with activated carbon and secondary with three clays from Ivory Coast. Activated carbon was prepared from coconut shell by a simplified procedure, without chemical additives, in order to obtain an economic and ecological adsorbent. The three raw clays (Dabou, Yamoussoukro and Katiola) each underwent purification operations to obtain pure fractions. Characterization tests including various techniques (elemental analysis, XRD, nitrogen adsorption, IR, etc.) were carried out on the adsorbents obtained. Adsorption tests carried out with the coal showed that no elimination of HA was observed. The main reason is the lack of functional groups on the surface of the prepared coal. The adsorption tests conducted with the clays have shown that these materials are capable of removing HA. The results revealed that the clay richest in kaolinite (Yamoussoukro) has a much higher maximum adsorption capacity (115 mg/g) compared to the others (20 and 15 mg/g for Dabou and Katiola respectively). This difference found its explanation in the mineralogical and structural composition of each of the clays. Photocatalysis tests showed a degradation of the macromolecules of HA into smaller sizes compounds. The mineralization of the organic matter was observed with total organic carbon reduction rate equal to 72 and 82% at pH 7 and 3 respectively. By placing in series the two processes namely adsorption followed by photocatalysis, the removal percentage of HA obtained at pH 3, is about 95%. This hybrid process shows an advantage since it makes it possible to eliminate almost all of the initial organic pollution

When people (or organizations) exchange gifts, there are more meaningful interventions in those acts than actions of offering, accepting and thanking (giving back or not) may seem to express. Concepts related to situations and purposes that are ingrained in the memory of the past and that will determine relationships in the future are created or reinforced. The present work aims at highlighting the simple habit of giving gifts, so common that it passes by unnoticed but which can help build and strengthen bonds. Among different organized social groups there is no survival without support, as there is not a person who is not a giver and a receiver of attention at the same time, either by objective means that can be evaluated directly or by abstract actions, which are less likely to be defined. All in all, there is a wide range of possibilities to find some criteria in writings from different authors in several areas (already defined) of knowledge and others begin to form. The essential reciprocity of the gift is the common element of communication and its equivalent reason for existing: without reciprocity there is no communication, there is no social group that can organize itself and therefore survive. It is in this reciprocity of attention (and of objects) that knowledge is added, new habits are created, and cultures can mingle and integrate: these are the simultaneous experiences and experimentations which establish inclusion amongst common cultural background. In the present research, the foundation for the understanding of rituals of object exchanging as social contracts is laid on the works of authors such as Mauss and Bystrina while the look on the Latin-American reality, especially the Brazilian one, is from Gruzinski, Canclini, and (Viveiros de) Castro, which show what was, is and can be the exchange of gifts as the creation of new contexts that include different cultures. Other authors are important for the course of the research and many are not mentioned here but they are crucial for the beginning and the end of the purpose of this study. Objects which are gifts (bonding celebrations) and presents (that keep their memories in the absence), indicate alterations incorporated in situations of giving presents, hypothesis of this research when analyzing the communication strategy in company cases and real life examples
Quando pessoas (ou organizações) trocam presentes existem mais significados intervenientes do que fazem parecer as ações de oferecer, aceitar e agradecer (retribuindo ou não). São criados, ou reforçados, conceitos vinculados às situações e propósitos que estarão na memória do passado e pautarão o relacionamento no futuro. Está ai o percurso deste trabalho que procura dar destaque ao hábito banal do presentear, tão comum que não chama a atenção, mas que tem importância muito especial para que vinculas se construam e fortaleçam. Entre diferentes grupos sociais organizados, não há sobrevivência sem apoio, como não há pessoa que não seja, ao mesmo tempo, doadora e recebedora de atenção daqueles que a cercam, seja por meio de objetos concretos de possível avaliação direta, ou de ações abstratas, pouco passáveis de configuração ou definição. Entre uns e outros, há uma enorme gama de possibilidades para as quais se fazem aqui indicações de alguns critérios que podem ser encontrados em vários autores de muitos campos dá definidos) do conhecimento e outros que começam a se delinear. A reciprocidade essencial da dádiva é o elemento comum para a comunicação e seu equivalente motivo de existência: sem reciprocidade não há comunicação, não há grupo social que se organize e, portanto, sobreviva. É nessa reciprocidade de atenção (e de objetos) que se acrescentam conhecimentos, criam-se novos hábitos, misturam-se e integram-se culturas: são as experiências e experimentações simultâneas que estabelecem a inclusão entre mútuos repertórios culturais. Nesta pesquisa, a base para o entendimento dos rituais de trocas de objetos como contratos sociais está em autores como Mauss e Bystrina, enquanto o olhar que aproxima a realidade latino-americana, em especial a brasileira, foi encontrado em Gruzinski, Canclini, e (Viveiros de) Castro, que nos indicam o que foi, é, e pode ser a troca de presentes como criação de novos contextos que incluam diferentes culturas. Outros autores são importantes para o percurso da pesquisa, e muitos não estão aqui incluídos, mas são fundamentais para os momentos de partida e de chegada ao propósito deste estudo. Objetos que sejam brindes (comemorações de vinculação) e presentes (que mantenham a memória na ausência), indicam alteridades incorporadas nas situações de presentear, hipótese desta pesquisa ao analisar a estratégia comunicacional das organizações em casos e exemplos reais

El presente trabajo ha sido elaborado bajo la identificación de una problemática que enfrentan en su día a día muchas personas, a quienes en adelante se llamará público objetivo. La propuesta de este trabajo es ofrecer al mercado un sitio web donde ellos puedan encontrar paquetes de regalos, los cuales contengan un mix de productos que se adapte a los gustos y preferencias de la persona a quien piensan dirigir el regalo. Se considero los paquetes de regalos pues en la actualidad en el mercado de regalos y/o obsequios los usuarios suelen buscar un mix de productos en un solo lugar pues esto reduce el tiempo de búsqueda de un regalo en tiendas independientes y lo más importante, produce un ahorro en sus bolsillos. Ese fue el motivo por el cual se consideró un mercado atractivo que aún puede mejorar ofreciendo alternativas de compra llamativas que se adapten a los gustos de los interesados. Es por ello que nació Kamari, una tienda de regalos online en la cual se puede elegir entre una serie de distintos paquetes a regalar dependiendo de la ocasión e incluso cambiar ciertos productos del paquete seleccionado, haciéndolo personalizable para el cliente. Cabe mencionar que para corroborar la viabilidad de este proyecto el equipo de trabajo ha elaborado experimentos para la validación del proyecto a pesar de la situación actual que se vive a nivel mundial, logrando como resultado un proyecto viable.
This work has been prepared under the identification of a problem that many people face in their day-to-day life, who from now on will be called the target audience. The proposal of this work is to offer the market a website where they can find gift packages, which contain a mix of products that adapts to the tastes and preferences of the person to whom they plan to direct the gift. Gift packages were considered as currently in the market for gifts and / or gifts, users often look for a mix of products in one place as this reduces the time of searching for a gift in independent stores and most importantly, produces a savings in customer´s pockets. That was the reason why it was considered an attractive market that can still improve by offering eye-catching purchasing alternatives that suit the tastes of those interested. That is why Kamari was born, an online gift store where you can choose between a series of different packages to give away depending on the occasion and even change certain products from the selected package, making it customizable for the client. It is worth mentioning that to corroborate the viability of this project, the work team has carried out experiments for the validation of the project despite the current situation worldwide, achieving as a result a viable project.

Streszczenie:

Els virus JC i BK pertanyen a la família Polyomaviridae i fan infeccions al ronyó d'un 60-80% d'individus adults arreu del món sense causar en principi cap simptomatologia. En condicions d'immunosupressió JC pot ocasionar una malaltia letal del cervell anomenada leucoencefalopatia multifocal progressiva (PML) que afecta un 4% de pacients de SIDA, BK pot ocasionar nefropatia en pacients trasplantats de ronyó. Ambdós virus s'han relacionat recentment amb tumors de cervell i JC amb tumors colorectals. La ruta de transmissió d'aquests virus roman desconeguda.
Entre els anys 1955-1961, SV40, un poliomavirus que infecta micos rhesus, va ser administrat a la població en ser un contaminant de les cèl·lules utilitzades per produir les vacunes de la polio. Recentment, SV40 ha estat detectat en tumors humans i la possibilitat de que infecti la població està sent considerada.
L'objectiu d'aquesta tesi doctoral va ser el d'estudiar l'excreció d'aquest virus per part de la població de diverses zones geogràfiques. En la primera part de l'estudi es va dissenyar un mètode per detectar els poliomavirus BK, JC i SV40 en mostres d'aigua residual urbana i altres mostres ambientals. La detecció de virus en aquestes mostres permet estudiar els virus excretats per comunitats senceres en un moment i en un indret determinat. El mètode desenvolupat va permetre concentrar i detectar per PCR niada les partícules víriques (PV) de JC, BK i SV40 presents en un total de 52 mostres d'aigua residual urbana de Barcelona, Umeå (Suècia), Nancy (França), Pretoria (Sudàfrica), Cairo (Egipte), Patras (Grècia) i Washington DC (EUA). També es va estudiar la presència de poliomavirus humans i SV40 en 10 mostres de mol·luscs bivalves (Tarragona) i en 23 mostres ambientals del Nord de la Índia.
Es van detectar elevades concentracions de JC i BK (10 elevat a 3 i 10 elevat a 2 PV/ml respectivament) i absència de resultats positius per SV40. Es va estudiar l'estabilitat a 20ºC dels JC i BK presents en aquest tipus de mostres.
En una segona part de l'estudi, els virus detectats van ser tipificats, analitzats filogenèticament i l'estructura de la seva regió reguladora (RR) va ser caracteritzada. L'estudi de la regió intergènica (RI) de JC va permetre construir un arbre filogenetic que relacionava les soques detectades amb l'origen ètnic de les poblacions estudiades. L'estudi de la RR de JC va permetre concloure que la majoria dels JC presents en aigües residuals presenten una configuració arquetípica d'aquesta regió (al igual que passa amb BK) tot i que es va detectar un petit percentatge de soques amb RR reorganitzades en l'aigua residual de Washington DC. En la tercera part d'aquest estudi, es descriu per primera vegada com PV dels JC i BK arquetípics presents en una mostra d'orina d'una dona embarassada van infectar cèl·lules SVG.
JC Mad-4 (soca control) tractat amb tripsina va infectar cèl·lules SVG al igual que Mad-4 sense tractar. Mad-4 tractat amb pH 3 durant 1 hora va infectar les cèl·lules produint però un descens en el títol de la progènie.
Aquests resultats ens van fer suggerir una ruta de transmissió de JC a partir d'aigües o aliments contaminats a través del tracte gastrointestinal.
Es va estudiar l'excreció de les PV de SV40 excretades per una població de micos Cynomolgus naturalment infectats amb el virus. Es van detectar soques arquetípiques de SV40 en la meitat de les gàbies analitzades confirmant que el mètode desenvolupat permet detectar SV40 en mostres ambientals. L'absència de SV40 en les mostres estudiades indica que el virus no està sent excretat per la població estudiada que està present en molt baixes concentracions (<5PV/ml d'aigua residual).

Streszczenie:

As social interactions increasingly become exclusively online, there is a need for research on the role of identity and social identity in online platforms. Drawing on Symbolic Interactionist approaches to identity, namely Social Identity Theory and Identity Theory, as well as Signaling Theory, this study argues that actors will selectively use religious language to signal their credentials to an audience for the purpose of garnering prosocial behavior in the form of donations to their fundraising campaign. Using latent semantic analysis topic models to analyze the self-presentations of crowdsourcing campaigners on GoFundMe.com, this study found evidence for the presence of signaling to a religious identity online as well as a significant difference in the presentation of need for campaigns originating in areas with high reported religiosity compared to campaigns from areas of low religiosity. In comparison to other campaigns, campaigners engaging in religious signaling were significantly increasing their donations. I suggest that strategically chosen religious topics in online crowdfunding is an example of low-cost identity signaling and provides insight into how signaling happens online and the potential outcomes resulting from this cultural work.

Nous avons etudie par spectroscopie vibrationnelle a haute resolution les centres lies a l'oxygene et a l'hydrogene dans certains cristaux d'arseniure de gallium semi-isolants.

On presente une etude detaillee de la capture des photo-porteurs par ce centre, en liaison avec la presence dans le materiau du centre profond el2. La capture se traduit par une variation des intensites relatives des trois modes. L'un d'eux est observable seulement apres capture de porteurs a basse temperature car le centre a une energie de hubbard negative. L'etude spectroscopique sous contrainte uniaxiale montre que le centre possede une symetrie rhomboedrique pour les trois etats de charge et que l'atome d'oxygene est lie a deux atomes de gallium seconds voisins. On observe aussi un mode de l'oxygene interstitiel lie a un atome as et un atome ga premiers voisins. Ce centre est electriquement inactif. Les mesures sous contraintes montrent qu'il possede une symetrie trigonale et que son energie de reorientation moyenne est d'environ 1 ev. Nous observons aussi dans les echantillons des modes qui montrent la presence de complexes oh et nh dont certains sont electriquement actifs.

Streszczenie:

La soca de ratolins amb senescència accelerada SAMP8 és utilitzada habitualment com a model de senescència; i el seu ús per a l’estudi de la malaltia d’Alzheimer s’ha estès degut a la manifestació espontània dels seus trets histopatològics distintius. En estudis recents es va identificar la presència de grànuls amiloides a l’hipocamp dels ratolins SAMP8. Aquests clústers de grànuls augmenten amb l’edat i s’estenen al llarg de l’hipocamp. A més a més, les característiques morfològiques dels grànuls amiloides són molt similars als grànuls tenyits amb Periodic Acid Schiff (PAS), descrits anteriorment en els SAMP8 i en ratolins envellits d’altres soques. L’objectiu principal d’aquesta tesi ha estat estudiar la composició, l’origen i el desenvolupament dels grànuls que apareixen amb l’edat a l’hipocamp dels ratolins senescents SAMP8 amb la finalitat d’aportar nova informació sobre la neuropatologia d’aquests ratolins per al seu ús com a model de la malaltia d’Alzheimer. En aquest treball s’ha identificat la correspondència entre els grànuls amiloides i els grànuls PAS de l’hipocamp d’aquests animals. Aquests grànuls són el resultat d’un procés degeneratiu present en els astròcits i que pot afectar també zones properes, i estan formats per fragments membranosos provinents de l’acumulació de restes d’estructures i orgànuls, com els mitocondris. A més a més, s’ha identificat la presència d’un neo-epítop en el nucli dels grànuls que és, almenys parcialment, de naturalesa glucídica. Aquest neo-epítop és reconegut per anticossos IgM contaminants presents en anticossos comercials produïts en ascites de ratolí o sèrum de ratolí i conill. Aquestes IgM contaminants són probablement anticossos naturals, i algunes IgM hemaglutinen de forma positiva i específica els eritròcits humans de tipus A. La presència tant del neo-epítop com de les IgMs han estat la causa de falses tincions positives que han generat interpretacions errònies del significat fisiopatològic dels grànuls. És el cas, per exemple, de la presència de β-amiloide o la proteïna tau en aquestes estructures. Finalment, les lesions cerebrals de pacients associades a malalties neurodegeneratives i a l’envelliment no corresponen als clústers de grànuls de l’hipocamp d’aquests ratolins, tot i que seria interessant estudiar la presència del neo-epítop en aquestes condicions fisiopatològiques.
SAMP8 mice present an accelerated senescence and are usually used as a model of aging. Because this strain of mice spontaneously expresses several histopathological features of Alzheimer’s disease (AD), it has been recently used as a model for studying this disease. Alterations in the expression of β-amyloid (Aβ) peptides, tau hyperphosphorilation, an increase of oxidative stress and gliosis suggest that SAMP8 mice could be a relevant model for studying the first stages of sporadic AD and its relation to aging. Recent studies in our group identified the presence of Aβ clustered granules in the hippocampus of SAMP8 mice when immunohistochemical stainings were performed with antibodies directed against Aβ peptides. These clustered granules increase in number and extension with age, and they spread throughout the hippocampus. The features of Aβ clustered granules are very similar to the granules stained with Periodic Acid Schiff (PAS) already described in SAMP8 mice, as well as in aged mice of other strains. On the other hand, human brain lesions present in aging and other neurodegenerative diseases, such as AD, may vary their chemical composition with time, suffering substantial alterations in the principal components and the addition of secondary components. The main objective of this thesis is to study the composition, origin and development of the granules that appear with age in the hippocampus of SAMP8 mice, with the aim of further describing the neuropathology of these animals and provide new information for using them as a murine model of AD. Therefore, in this thesis we studied the composition and order of appearance of the constituents of the hippocampal granules of SAMP8 mice, and the possible coincidence between Aβ and PAS granules. The morphology, ultrastructure, cellular origin and formation process of these structures has been also ascertained; and a comparison between these structures and human brain lesions of neurodegenerative diseases have been performed. The results obtained in this thesis allowed reaching several conclusions. The pathological clustered granules of the hippocampus of aged SAMP8 mice correspond to the PAS granules described in aged mice of several mouse strains. These granules are the result of a degenerative process located in astrocytes that could affect the surrounding neuropil. In the granules formation process, several abnormal membranous structures and cellular organelles, like mitochondria, produce membranous waste that finally accummulates forming the core of the granules. On the other hand, a neo-epitope absent before the granules formation appears in the membranous residues. This neo-epitope is located in the nucleus of the mature granules and contains at least some structures of glycosidic nature. The neo-epitope is recognized by contaminant IgM antibodies present in a wide range of commercial antibodies produced in mouse ascites or mouse and rabbit sera, which are probably natural antibodies, and some of these IgMs haemmagglutinate A-type human erythrocytes, but not B and O subtypes. The neo-epitope could be considered an A-like epitope because monoclonal antibodies anti-A-type human erythrocytes do not recognize it. Both the neo-epitope presence in the granular structures and the IgMs contained in commercial antibodies have been the cause of false-positive stainings, and as a result, they have generated misunderstandings about the composition and physiopathological significance of the hippocampal granules of aged mice, as is the case of Aβ peptides and tau protein, which are not contained in these granules. Finally, human brain lesions described to date in patients of neurodegenerative diseases or aged individuals do not correspond to the clustered pathological granules present in the hippocampus of aged mice. The study of the presence of the neo-epitope in diseased human brain could be interesting in the understanding of the neuropathology of aging and neurodegenerative diseases.

Organoleptic properties of water are the only means whereby a consumer can assess water quality and safety. Among these properties, taste and odour are the most important. The first part of this study displays the water bottles that showed obnoxious odour with the aim of relating the analyte that generated that off-odour to a defined smell. The second part contains a deep study about the analytes coming from the packaging, cleaning and bottling processes. To isolate the volatile (VOCs) and semivolatile (SVOCs) organic compounds capable of generating off odours, the extraction method Closed Loop Stripping Analysis (CLSA) has been optimized. In relation to packaging materials, SDE (Simultaneous Distillation Extraction, aka Likens-Nickerson) extraction method has been applied. Liquid-liquid extraction method has also been applied in several isolations. As regard identification and quantification of compounds extracted a method has been established by means of gas chromatography coupled to mass spectrometry (GC-MS). Quality parameters of the most meaningful compounds, which have been found most frequently, have been calculated. Smell descriptors like "earthy-musty", "rotten", and "gasoil" have been matched with their generating compounds. Several compounds coming from the bottles, caps and cleaning processes have been isolated and identified. In addition, several causes that could generate some off-flavour in water have been suggested.
Les propietats organolèptiques de l'aigua són la única via per la que un consumidor pot avaluar la seva qualitat i seguretat. De les esmentades propietats, el gust i la olor són les més importants. En la primera part d'aquest estudi s'han analitzat mostres d'aigua envasada que presentaven olors anòmales amb l'objectiu de relacionar l'analit que generava la mala olor amb una olor definida, i en la segona part s'ha profunditzat més en els analits provinents de l'envàs i dels processos de neteja de l'embotellament. Per a l'aïllament dels compostos orgànics volàtils (VOCs) susceptibles de generar l'olor anòmala s¿'ha optimitzat el mètode d'extracció closed loop stripping analysis (CLSA) mentre que per a l¿'estudi dels materials de l'envàs s'ha emprat la tècnica de destil·lació i extracció continua (SDE) també coneguda com a Likens Nickerson. Pel que fa a la identificació i la quantificació dels VOCs s'ha establert un mètode amb la tècnica de cromatografia de gasos acoblada a un detector d'espectrometria de masses (GC-MS). S'han calculat els paràmetres de qualitat del compostos més significatius trobats amb més freqüència. S'han pogut definir descriptors d'olors com "terra/mullada", "podrit" i "derivats de petroli". S'han descrit una sèrie de compostos provinents de l'ampolla, dels taps, dels processos de neteja de l'embotellament i de la contaminació externa. També es proposen una sèrie de causes que justificarien la presència dels compostos en aigua envasada trobats en aquets estudi. La concentració dels analits determinats en aquets estudi és de l'ordre de ng/L i no suposen cap risc per a la salut.

Streszczenie:

Les espèces chimiques contenues dans les matrices solides sont susceptibles d'être transférées vers le milieu ambiant, notamment lors de leur contact avec l'eau. Les études précédentes du relargage des métaux lourds traces contenus par les matériaux de construction (en particulier ceux à base de ciment) lors d'essais de lixiviation, montrent une difficulté analytique importante. L'objectif de cette étude est de déterminer les cinétiques et les mécanismes de relargage de métaux traces (Cr, Cu, Ni, Pb, V et Zn) des pâtes de ciments industriels (présents à des teneurs de l'ordre de 20 à 300 ppm).

Le développement du test de lixiviation dynamique CTG-LEACHCRETE (utilisé à pH=5, 20°C) permettant d'accéder aux cinétiques de relargage des métaux lourds traces est présenté dans une première partie. Ensuite, des techniques d'analyse du solide (ICP-MS-LA, DRX locale et en incidence rasante (GIXD)), novatrices quant à leur application aux matrices cimentaires, ont été employées pour caractériser les zones dégradées générées lors de la lixiviation. Ces techniques permettent de suivre les transformations minéralogiques et la répartition des métaux lourds traces dans ces zones. La confrontation de ces deux approches, cinétique et analyse du solide, couplée à l'exploitation approfondie des modélisations existantes a alors permis de proposer les mécanismes de relargage des métaux lourds traces étudiés.

Dans toutes les pâtes de ciments de l'étude (CPA-CEM I, CPJ-CEM II/A et CLC-CEM V/A), on a démontré que le chrome est piégé dans l'ettringite par substitution SO42-ÛCrO42- et que son relargage est régi par la dissolution de cet hydrate. Le comportement du cuivre, du nickel et du zinc dans les phases solides et dans les lixiviats, est corrélé à celui de la silice des CSH, ce qui suppose que ces métaux s'y trouvent localisés. Enfin, le plomb n'est jamais détecté en phase liquide. Son comportement est également corrélé à la silice dans les zones dégradées.

Streszczenie:

Focusing on the everyday lives of middle-class English families in a medium size town situated in the Midlands, this doctoral thesis contributes to anthropological debates on the topics of human agency, time, domesticity, mothering, and kinship. Organized upon the idea that cultural models of time are inextricably linked to understandings of agency (Greenhouse 1996), the thesis links Moore s (2011) post-vitalist theoretical framework and the work of Foucault (1990, 2000) on ethical practices, with Gershon s (2011) critique of neoliberal agency . The concept of ordinary agency is proposed for situating everyday actions as significant actions that contribute to social transformation. Three cultural models of time are identified spontaneity, anticipation and family time and the types of ordinary agencies that they engage are described in three dedicated chapters. The first chapter discusses the theoretical framework of the thesis. The second chapter addresses methodological issues, and discusses the methods that the author developed during her ethnographic fieldwork for looking at people s relationships with time. The third chapter addresses the time mode of spontaneity, presenting ethnographic examples of digital media use at home, and introducing theoretical tools for situating the forms of agency engendered by spontaneity. The fourth chapter looks at the time mode of anticipation in relation to mothering, motherhood and care. This chapter is accompanied by a video component, titled Mum s Cup and situated in the appendix of the thesis. Based on material that the participants filmed in solitude, for a self-interviewing with video task, Mum s Cup is a visual point of departure for theorising the Mother-Multiple ontological position that is described in chapter IV. Alongside providing a visual ethnographic lever for endorsing a theoretical concept, the video project also reflects on the relationship between the researcher and the participants, a relationship that, for various reasons (some related to length limitations), is not fully described in the textual corpus of the thesis. Discussing two types of domestic sociality, the fifth chapter looks at family time and at the forms of agency engendered by the idea and by the experience of having a family-style lifestyle (Strathern 1992), and it draws on, and contributes to, bodies of literature on English kinship. The last chapter addresses the context of the research which is an interdisciplinary project looking at domestic energy consumption ; it situates the position of the author in relation to the domestic sustainability agenda and to debates on interdisciplinarity, and it formulates ideas about possible applications that the anthropological knowledge gained by the author through her research could have in relation to the context that originally framed and facilitated the research.

Confronting the realisation that one's child may have a developmental disability presents a major challenge for any parent. The body of scholarship in this area however, focused mainly on the role that mothers play highlighting a distinct gap within the literature. In an attempt to address this, my study aimed to explore the subjective experiences of fathers parenting a child that presents with dyspraxia during middle childhood. This aim translated into the following objectives: to understand the subjective experiences of fathers parenting a child that presents with dyspraxia during middle childhood; to explore the challenges faced by fathers in parenting a child that presents with dyspraxia during middle childhood and to identify the support structures available and support required by fathers parenting a child that presents with dyspraxia during middle childhood. This study was theoretically located within Bowen's Family Systems Theory and the Family Resilience Framework. Philosophically the methodology was grounded within an Interpretivist Framework using a qualitative approach. Consistent with this approach, 14 semi-structured individual interviews were conducted. Fathers were purposively recruited from across the Cape metropole area and were asked about their subjective experiences in parenting a child that presents with dyspraxia. Permission to conduct the study was obtained from the Senate Research Ethics Committee (Social and Human Sciences) of the University of the Western Cape. Participation was completely voluntary and could be withdrawn at any stage. Ethics principles were strictly adhered to throughout the entire process. The transcriptions were subjected to a thematic analysis in which three thematic domains emerged namely; Experiences, Challenges and Support. The thematic domain of Experiences revealed their initial reactions, their emotional responses, their innovative teaching methods and their expectations with regard to their child. The Challenges thematic domain highlighted issues of health literacy, their sense of helplessness, how interactions were circumscribed, the acquiescence of the respective schools and the lack of support that they experienced. The Support thematic domain revealed the external and internal support sources for these fathers. Based on the findings of the study, the recommendations are to create an informal support network of parents and health professionals to share information and to offer a practical guide for parents to utilise in the treatment of their child at home. The findings also revealed that alternative understandings of fathering need to be developed to enable new and more equal ways of being both fathers and men and mothers and women. This is necessary to challenge the limiting essential notions of what is possible for men and women.

Streszczenie:

La tesi parteix del pensament de maduresa de Hannah Arendt (Hannover 1906- New York 1975), expressat, entre d’altres escrits, a les obres The Human Condition (1975) i The Life of the Mind (1978). Amb aquesta base, la recerca es retrotrau al pensament de joventut de Hannah Arendt, reflectit en la seva tesi doctoral sobre el concepte d’amor en Agustí de Hipona, Der Liebesbegriff bei Augustin (1929) i en un altre text, Rahel Varnhagen: the Life of a Jewess, escrit abans del 1933 però publicat vint anys més tard, el 1958. Una de les finalitats d’aquesta tesi és investigar la continuïtat o abandonament de la filosofia i les idees d’aquella primera etapa marcada fortament per la influència intel·lectual de Heidegger y Jaspers. No obstant, el propòsit no és examinar exhaustivament la influència dels seus mestres ni de l’existencialisme, la fenomenologia o l’ontologia, sinó més aviat detectar i evidenciar la gran importància de les petjades agustinianes procedents de l’època de la seva formació acadèmica i veure en quina mesura perviuen metamorfosejades en les categories polítiques fonamentals de l’obra madura de l’autora. El text sobre Rahel Varnhagen, fa possible plantejar la identitat jueva d’Arendt i també la seva condició de dona o “feminini generis” com digué ella mateixa. Permet també reprendre des d’un angle diferent les categories centrals, i examinar la relació del romanticisme alemany, a través de Rahel Varnhagen, amb la formació filosòfica i experiència vital de l’Arendt jove en el context de l’existencialisme i el marxisme durant els anys en què es gestà i culminà el nazisme a Alemanya. Aquestes dues obres de joventut, escassament estudiades fins el present, permeten un apropament a una Arendt amb trets intel·lectuals i personals forts i contrastats, que perfilen ja el pensament polític posterior de Hannah Arendt. La recerca mostra com l’accent polític del pensament arendtià va en augment fins assolir la idea que és necessari defensar l’esfera pública atès que la vida política és en perill a causa de l’emergència d’un àmbit intermedi o híbrid entre públic i privat, és l’àmbit social o la societat regida per la noció d’igualtat. Aquesta qüestió s’examina a la llum de l’anàlisi arendtià de la filosofia marxiana en els seus escrits Karl Marx and the Tradition of Western Political Thought. Una de les qüestions principals plantejades en aquesta recerca és la triple condició de Hannah Arendt, tres identitats forjades a través de l'experiència física i espiritual. Hi ha una contumaç recurrència a la noció d'experiència per part d'Arendt, que du inevitablement a pensar en aquesta pluralitat de personatges construïts a partir de les experiències viscudes en la pròpia carn, en cos i esperit: l'Arendt jueva, l'alemanya i l'americana. També el món greco-romà exercí una gran fascinació en Hannah Arendt, atesa la destacada importància que Arendt atorga a la fundació de Roma, a Agustí, a Ciceró i a Virgili, però la "polis" i la "civitas", no van constituir la seva identitat sinó que van ser el referent clàssic del seu pensament polític. En Arendt no hi ha cap nostàlgia ni desig de retorn al passat. Arendt denuncia no l'oblit del passat sinó el del present, l'oblit del món comú i del viure junts. L'Arendt jueva és la dona que va néixer en una família assimilada de Königsberg, que va créixer enmig dels costums jueus, i que ja adulta va esdevenir una pària conscient de la seva judaïtat perquè va ser expulsada de la terra on havia nascut, desposseïda de la ciutat, de la gent, de la llengua i del món que sentia seu. Aquesta catàstrofe la va fer sentir-se jueva i rebel, va comprendre que havia de defensar-se des de la condició per la qual havia estat atacada. Arendt, a pesar de les crítiques i de la seva condició, d'assimilada conscient, mai renuncià ni abdicà de la seva condició jueva. L'Arendt alemanya és sobretot la defensora de la llengua materna, a banda de la seva explícita declaració, es constata en les referències a la poesia i la literatura alemanyes, en la manera d'escriure d’Arendt, i en la crítica que adreça a qui vol fer com si pogués pensar i identificar-se amb paraules estranyes. L'Arendt americana és la refugiada, la pària que amb la seva qualitat personal ha adquirit una ciutadania nova, ha tornat a començar. Els Estats Units, recullen en el pensament arendtià les referències mítiques del món grec i llatí, de la fundació i la república, en l'experiència americana el passat mític de l'origen coincideix amb el futur d'un món nou i un nou ordre, en un present ple de contradiccions però pel qual Arendt sentia gratitud. La tesi examina la metodologia arendtiana fins arribar a clarificar i formular les quatre línies mestres del mètode emprat per Arendt: la recuperació de fragments i muntatge de citacions, les conceptualitzacions diferenciadores, la doble interpretació i finalment l’exercici o experiència de pensament que s’expressa mitjançant l’assaig. Amb aquest plantejament es refusen les crítiques que qualifiquen Arendt de pensadora asistemàtica, i contradictòria. Els autors emprats per a examinar aquest aspecte metodològic han estat Kant, Nietzsche, Benjamin i Adorno.
The main objective of this research consists of detecting and bringing to light the question about whether there was a continuity in the thinking of Hannah Arendt or, on the contrary, there was a break or an abandonment between the ideas and experiences of her youth and her mature thinking. This topic is shown at the subtitle, which mentions the main actors of two Arendt works: Love and Augustine (1929) and Rahel Varnhagen, the Life of a Jewess (1958). Although the latter work was published for the first time twenty years later, it was written by Arendt before 1933, except for the two last chapters (1938), so both books were youth works. Augustine was related to Arendt’s academic studies and, moreover, to German Existenz Philosophy, which she analyzed and compared with French Existentialism. However, she cannot be considered an existentialist. Rahel Levin (Varnhagen) was related to Arendt’s Jewish identity, to her woman’s condition or, as she said, “feminini generis”, and to the German romanticism. Those works and the problems outlined in them are contrasted with the last work The Life of the Mind in which Arendt reviews, especially in the book devoted to Willing, Augustine’s philosophy from a new perspective. The research shows how the accent on politics increases until Arendt reaches the idea that it is necessary to save the public realm since political life is everywhere under siege because of the emergence of “society” and “equality”: the former was the most important phenomena while the latter was the main social notion of Modern Age. Regarding this matter, the research discusses Arendt’s analysis of Marxism in Karl Marx and the Tradition of Western Political Thought and the categories of “labor, work and action” in her main work The Human Condition. Another objective of this research is to clarify Arendt’s method. It has been said that Arendt was an anti-systematic thinker who posed paradoxical or contradictory questions. Some of the authors that have been useful to analyze this problem are Kant, Nietzsche, Benjamin and Adorno.

Streszczenie:

Ce travail est consacré à l'élaboration d'un procédé de détection en temps réel des polluants métalliques présents dans les effluents gazeux industriels. La méthode de mesure est la spectrométrie d'émission atomique couplée à une torche ICP (Inductively coupled Plasma).
La technologie des lits fluidisés est utilisée comme système d'introduction des particules métalliques dans la torche ICP, l'intérêt du principe de détection reposant sur l'affranchissement de la procédure usuelle d'étalonnage du système analytique.
Les résultats sont présentés en deux parties. La première concerne le diagnostic de plasmas formés de différents mélanges N2/O2 dont un correspond à l'air pur, la seconde présente la mise en œuvre du procédé de détection en temps réel à partir des rapports d'intensités des raies spectrales de l'élément métallique avec celles de l'élément plasmagène (argon ou air pur).
L'étude du diagnostic de plasmas composés de mélanges N2/O2 concerne la détermination de la température d'excitation atomique à partir des raies spectrales de l'élément cuivre et l'évaluation du degré de déséquilibre thermique q =Te/Th régnant au sein du plasma. Ce dernier est obtenu en considérant les enthalpies massiques des différents mélanges N2/O2. L'existence d'un léger déséquilibre thermique (q£1,2) est mis en évidence.
L'étude de la détection en temps réel par torche ICP, sans étalonnage du système, repose sur trois points :
- le traitement des données spectroscopiques pour déterminer les valeurs des rapports d'intensités de raies spectrales;
- l'insertion des rapports d'intensités et des caractéristiques du plasma (argon ou air pur) dans un code de calcul de composition du plasma;
- la comparaison des valeurs de débits massiques des polluants métalliques, en temps réel, obtenues expérimentalement avec celles calculées à partir des formules d'élutriation, terme qui définit le phénomène d'entraînement des particules hors du lit fluidisé.
Les résultats ont permis de montrer la similarité de la réponse du système analytique entre l'utilisation du plasma d'argon et celui d'air.

Hem pretès amb aquesta Tesi acostar-nos a l'estudi dels noves configuracions identitàries que estan donant-se en un moment històric com l'actual, de profundes transformacions socials en els països occidental-capitalistes. Aquest moment podem caracteritzar-lo pel desmuntatge i desacreditació del model social de l'Estat del Benestar, i per l'auge de les lògiques i models de govern neoliberals.En la confluència d'aquestes transformacions hem trobat un espai privilegiat d'investigació que ens permet estudiar aquestes noves configuracions identitàries: els Programes de Garantia Social -PGS-. Els PGS són una ferramenta formativa dirigida a joves entre 16 i 25 anys que no han superat l'educació obligatòria, i tenen un clar caràcter professionalitzador. Aquesta ferramenta educativa està travessada per les noves corrents que transformen la nostra societat, convertint-la en un lloc privilegiat per a observar la recerca de sentit de l'experiència identitària en el nostre temps.Amb aquesta intenció, entre els i les docents dels PGS en vigor al País Valencià en el curs 2001-2002, vam realitzat una sèrie d'entrevistes en profunditat a catorze. El criteri de selecció dels subjectes fou el de maximitzar la varietat potencial de discursos d'autocomprensió com a treballadors i treballadores. Per a aconseguir aquest criteri seleccionàrem docents de bàsica i de taller de set programes, de diferents tipus d'entitats promotores, amb diferents perfils professionals i amb diverses procedències geogràfiques. Realitzades les entrevistes, amb la intenció de localitzar i analitzar els discursos presents, treballàrem el material obtingut des del prisma de l'Anàlisi Social del Discurs.Per a poder establir els vincles entre el que 'diuen' les persones i el món que ens envolta vam aprofitar l'instrumental teòric plantejat en Boltanski i Thévenot (1991) i Boltanski i Chiapello (2002): la lògica de les ciutats. Aquest marc teòric posa l'èmfasi en dues dimensions del discurs que considerem clau, i que fan d'aquest model un model rellevant i fructífer: situa els discursos en relació amb el sistema econòmic i el moment històric en què circulen -dimensió sociohistòrica dels discursos-, i d'aquesta manera permet comprendre els seus efectes en l'ordre social -dimensió performativa dels discursos-.Els resultats obtinguts ens mostren certa diversitat discursiva dins d'un ordre, és a dir, apareixen diversos discursos no de forma casual, sinó en el marc d'un ordre de possibilitat. A més a més, trobem com aquesta varietat discursiva no duu directament a la presència de discursos crítics amb les noves lògiques de funcionament i de justificació del capitalisme flexible -ordre capitalista en què estem immersos actualment-, sinó que en la majoria dels casos ens trobem amb discursos afins o funcionals a aquest nou ordre; posant-se de manifest por últim la capacitat de fagocitació que aquest nou ordre té.
With this thesis we attempt to focus on the configuration of social identities nowadays. This processes are characterized by a historical moment in which Western capitalist countries are undergoing deep social transformations. One of the features of these are the destruction and discredit of the social model portrayed by the wellfare state. The rationale and model of neoliberal governance is increasingly featuring economic and working conditions of contemporaneity. At the crossroads of such transformations we have found a privileged arena for research: The Social Guarantee Schemes (SGS).SGS are a particular training scheme in Spain since the early 1990s aimed at young people with no educational qualification norvocational accreditation, and they try to equip them with a level 1qualification. Such schemes are crosscut by the newest forms of governance in our societies, which turns them into a privileged laboratory to observe the search of identity meaning in our time.In order to achieve our aims, we have carried out a series of in-depth interviews with fourteen trainers in SGS. The selection criteria we used attempted to maximize the potential variety of discourses of self-understanding as workers. The interviews allowedus to identify and analyze current discourses for which our perspective was that of social discourse analyses. We performed this approach relying upon the theoretical model developed by Boltanski and Thévenot (1991) and Boltanski and Chiapello (2002), which allowed us to establish the relationships between individual discourses and the context surrounding people eliciting them.The results we obtained show certain discursive diversity despite within an identifiable order. This variety is limited though, as we did not find any trace of critical discourses against or at least questioning the current rationales that justify flexible capitalism, the order that expands nowadays. Rather on the contrary, most discourses proved functional to this new order. This has led us to state the power to coopt different discourses that the new order shows.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO
Com base no procedimento EPA-3050B, estudou-se o teor de metais (Cd, Cr, Cu, Ni, Pb, e Zn) em lodos de esgoto da CETESB. Foram analisadas duas amostras e os resultados obtidos foram (Cd =3,4 ; Cr =367,5 ; Cu =263,0 ; Ni=290,6 ; Pb =91,5 ; Zn =1324,9 mg/ kg) para primeira amostra e (Cd =3,0 ; Cr =332,2 ; Cu =190,5 ; Ni=274,6 ; Pb =82,5 ; Zn =1284,2 mg/ kg) para segunda amostra, resultados estes inferiores aos descritos pela CETESB para amostras de lodo da mesma estação de tratamento. Dada uma potencial utilização deste material como adubo agrícola, foi determinada a fração disponível destes metais. Com exceção do níquel (25%), uma fração pequena dos metais estudados encontra-se na forma assimilável pelas plantas (< 20%), com base no procedimento descrito pela EMBRAPASolos (extração com DTPA). Os efeitos de uma eventual utilização de composto húmico mineral (CHM) como aditivo ao lodo, visando uma redução na fração assimilável de metais, foi estudada em função da quantidade de CHM aplicado e do pH da solução final. Os resultados obtidos demonstraram que o CHM possui um poder de complexação para os metais semelhante ao do DTPA e que, sua aplicação ao lodo de esgoto, teria, na realidade um efeito de potencializar a fração disponível de certos metais como o zinco.
Based on the EPA-3050B procedure, the concentration of metals (Cd, Cr, Cu, Ni, Pb and Zn) in sludge source at CETESB studied. Two samples were analyzed and the results obtained were (Cd =3,4 ; Cr =367,5 ; Cu =263,0 ; Ni=290,6 ; Pb =91,5 ; Zn =1324,9 mg/ kg) and (Cd =3,0 ; Cr =332,2 ; Cu =190,5 ; Ni=274,6 ; Pb =82,5 ; Zn =1284,2 mg/ kg). These concentrations were below those descried by SABESP for sludge samples measured in the same treatment station. Due to the potential utilization of these materials as manure in agriculture, the disposal fraction of these metals was determined. Except nickel (25%), a little fraction of metals studied is assimilated by plants (< 20%), base on the procedure already descried by EMBRAPA- Solos (extraction with DTPA). The effect of an eventual utilization to humic mineral compound (HMC), as additive in sludge, aiming the reduction of the assimilated fraction of metals, were studied in function of both, the amount of HMC applied and the final pH of the solution. The results obtained showed that HMC has a complexation potential for metals similar to DTPA and that, its application in sludge, has in fact, a potential effect on the disposal fraction of metals such as zinc.

Streszczenie:

La hipertensió és un dels principals factors de risc cardiovascular, sent el problema més important de salut pública i la principal causa de mort i discapacitat en els països desenvolupats. El primer pas per a prevenir la hipertensió és seguir una dieta saludable, com és la dieta Mediterrània i millorar l'estil de vida, augmentant l'activitat física o reduint el pes corporal. Diversos estudis epidemiològics relacionen de manera inversa el consum d'aliments rics en polifenols com el cacau, fruites, verdures i hortalisses (F&V), te, oli d'oliva verge, nous o vi, i el risc de mortalitat total o malalties cardiovasculars. L'objectiu principal del present treball ha estat posar a punt i validar la metodologia per a l'anàlisi dels polifenols totals en mostres d'orina i la seva correlació amb la hipertensió i la pressió arterial sistòlica i diastòlica en pacients d'alt risc cardiovascular.
S'ha desenvolupat un mètode sensible, específic, ràpid i senzill per a la quantificació de polifenols totals en un gran nombre de mostres d'orina obtinguda de forma puntual, amb un tractament de mostra molt senzill. Aquest mètode és més barat i respectuós amb el medi ambient en utilitzar menys reactius que els mètodes anteriors. La validació del mètode es basa en els resultats obtinguts a partir d'un estudi prospectiu aleatoritzat, creuat, amb diferents períodes d'intervenció i es va corroborar en un estudi transversal amb 60 voluntaris amb una població free-living. En aquests estudis es van trobar associacions positives entre els polifenols totals excretats en l'orina del matí, el consum de polifenols totals i el consum total de F&V; pel que es va poder considerar als polifenols totals excretats en orina com a biomarcador del consum de polifenols totals.
S'ha avaluat l'efecte del consum dels polifenols en la hipertensió arterial en 263 homes i 326 dones amb alt risc cardiovascular, amb edats compreses entre 55 i 80 anys, dins d'un sub-estudi transversal amb dades de l'estudi PREDIMED. En els individus en el quartil més alt d'excreció de polifenols totals, el risc d'hipertensió va disminuir en un 36% a comparació amb el quartil més baix d'excreció de polifenols totals. La ingesta de polifenols totals, avaluats a través de la seva excreció en orina, es va associar negativament amb els nivells de pressió arterial sistòlica i diastòlica. En un altre treball es van revisar els principals estudis epidemiològics que relacionen el consum de polifenols totals i la pressió arterial.
En l'últim treball es presenta un sub-estudi d'intervenció amb 1139 participants d'alt risc cardiovascular dins de l'estudi PREDIMED. Els participants van ser assignats a una dieta baixa en greix (dieta control), n=379 o a dues dietes estil mediterrània, una suplementada amb oli d'oliva verge, n=394 i l'altra amb fruits secs, n=366. La dieta mediterrània suplementada amb fruits secs o oli d'oliva verge es va correlacionar positivament amb els polifenols totals excretats en les mostres d'orina puntual. Novament els increments estadísticament significatius en l'excreció de polifenols totals, en un estudi d'intervenció, es van associar negativament amb la pressió arterial sistòlica i diastòlica, en una població mediterrània d'avançada edat. Per tant, una intervenció dietètica dirigides a incrementar la ingesta d'aliments rics en polifenols, podria ser eficient en la prevenció i el tractament de la hipertensió, unit a una disminució la pressió arterial, per tal de reduir el seu risc cardiovascular.
"The polyphenols present in food as functional components in the prevention and possible treatment of hypertension".

TEXT:

Hypertension is a major cardiovascular risk factors, being the most important problem of public health and the leading cause of death and disability in developed countries. The first step to prevent hypertension is to follow a healthy diet as the Mediterranean and improving lifestyle. The main objective of this study was to develop and validate the methodology for the analysis of total polyphenols (TP) in urine samples to evaluate if the TP in urine are correlated with polyphenol intake, to be considered as a marker of intake of these compounds, and its correlation with hypertension and systolic and diastolic blood pressure in patients at high cardiovascular risk.
We have developed a sensitive, specific, rapid and simple assay for quantification of polyphenols in a large number of spot urine samples. This method is cheaper and environmentally friendly by using less reactive than previous methods. It was performed a prospective randomized crossover trial and one cross-sectional study with 60 volunteers from the PREDIMED trial. These studies found positive associations between TP excreted in spot urine samples and consumption of TP, and with total fruits and vegetables intake.
We evaluated the effect of consumption of polyphenols in arterial hypertension in 589 patients at high cardiovascular risk, within the PREDIMED study. In individuals in the highest quartile of excretion of TP, the risk of hypertension decreased by 36% compared with the lowest quartile. The TP intake assessed by excretion in urine was negatively associated with levels of systolic and diastolic blood pressure. In the sub-intervention study (1139 participants), participants were assigned to a low-fat diet (n=379) or two Mediterranean-style diet. The Mediterranean diet supplemented with nuts (n=366) or virgin olive oil (n=394) were positively correlated with TP content excreted. Statistically significant increases in the excretion of TP were negatively associated with systolic and diastolic blood pressure after the Mediterranean diet supplemented. Therefore, a dietary intervention aimed at increasing the intake of foods rich in polyphenols, may be efficient in the prevention and treatment of hypertension, coupled with a decrease in blood pressure, to reduce their cardiovascular risk.

Streszczenie:

Esta tesis consiste en la aplicación de la electroforesis capilar (CE) a la separación y cuantificación de especies cianuradas y al estudio del comportamiento de estas especies y de su destino final. Como material de estudio se han seleccionado distintos procesos industriales (lixiviación de minerales y arenas auriferas, disoluciones de proceso en industrias de recubrimientos electrolíticos, lixiviación intensiva en autoclave de convertidores de automóvil) donde los cianuros tienen aplicación.

En la primera parte de la tesis se ha realizado un estudio detallado de las características de la técnica CE, y posteriormente se ha optimizado una metodología para aplicarla a los distintos problemas que se recogen en el resto de la memoria.

La segunda parte de la tesis se ha dedicado a la aplicación de la ce al estudio de la lixiviación con NaCN de los metales preciosos y estratégicos presentes en minerales auriferos (Au, Ag) y en convertidores de automóviles (PT, PD, RH), obteniendo finalmente un método analítico capaz de ser utilizado para el seguimiento de este tipo de procesos.

En la tercera parte de la tesis se ha realizado la determinación del cianuro libre, del débilmente ligado y del total en aguas procedentes de la industria de los recubrimientos electrolíticos y en disoluciones de cianuros oxidadas con hipoclorito, que es el método mas extendido para tratar las aguas industriales. Para analizar estas formas de cianuros, se han planteado dos soluciones, basadas en la detección indirecta y en la derivatización.

La problemática de la detección del cianuro libre (CN- y HCN (aq)) y de especies relacionadas (CNO-, SCN-, NO3, CI-, SO42- y CIO-) resuelto con la utilización de la fluorescencia indirecta con un detector prototipo con fuente láser.

La determinación de cianuros en muestras reales de disoluciones de recubrimientos electrolíticos se ha conseguido mediante su derivatizacion a NI(CN)42- utilizando una disolución de NI(II)-NH3.

Streszczenie:

Despite the general tendency of Greek to eliminate athematic verbal formations, new athematic -(v)vU/Cv)vti- presents continued to be created up until around the second century A.D. These presents can be divided into two main groups, namely those already attested in Homer and those with a post-Homeric fi rst attestation. The presents already attested in Homer can be divided into three categories, namely inherited presents, Old Formations and New Formations, according mainly to their manner of fo rmation and the coexistence, or not, of cognates in other languages. The inherited presents and the Old Formations were formed according to the patterns we are able to reconstruct for Indo-.European; the difference between them is that the latter do not have cognates in any other language. The New Formations, on the other hand, are built on a general verbal non-ablauting stem common to most forms of their verbal paradigm, including (he sigmatic aoris t. It was acruaUy through their sigmatic aorist that a series of transitive verbs, wru ch for various reasons lacked a present, came to be attracted to a paradigmatic scheme consisting of a sigmatic aorist paired with an athematic -(\I)\lu/(\I)\lU- present. Trus paradigmatic scheme was available exclusively for transitive verbs, offered by both the inherited presents and the Old Formations once Greek had solved a conflict of tran sitivity which originally existed between the primary and the characterized forms derived from semantically intransitive roots. In the present study the conclusion is reached that the creation of new athematic -(\I)\lu/(v)vu- presents was not at odds with the general tendencies underpinning the development of th e Greek verbal system, namely the elimination of athematic forms, because the (semi-)vocalic ending of the nasal suffix func tioned like a thematic vowel rurning the athematic -(\I)\lu/(\I)\lU- presents into a sort of pseudo-athematic fonnation. This conclusion is backed not only by the fact that over 84 % of the forms we have are attested in an actual athematic form, but it is also confirmed by the fact that Greek kept on creating new athematic - (v)v6/('J)vG- presents analogically in post-Homeric times. The coining of the post-Homeric new athematic -(v)vU/(v)vG- presents took place at twO chronologically different stages, the second of which occurs at around the beginning of the Christian era. The second and third volumes contain appendixes with supporting material: Appendix I consists of a catalogue of the athematic -('»v6/(\I)\I,j- present forms attested from Homer to the end of the second century A.D., and Appendix 2 consists of a series of tables in which the material of Appendix I is arranged according to a suitable set of categories.

Un incendie dans une installation nucleaire peut entrainer la liberation de matieres radioactives qui doivent imperativement etre confinees pour eviter tout rejet dans l'environnement. Pour se faire, les quantites et les formes physico-chimiques des produits radioactifs emis doivent pouvoir etre estimees. L'objectif de cette etude est d'apprehender experimentalement les phenomenes lies a l'emission d'aerosols radioactifs pour un scenario caracteristique d'incendie impliquant de l'oxyde de plutonium present dans une boite a gants. Dans un premier temps la mise au point de dispositifs et de protocoles experimentaux a permis la realisation d'essais reproductibles a petite echelle. Ces essais ont ete effectues dans une enceinte experimentale ou des echantillons de polymethacrylate de methyle (plexiglas) contamines par de l'oxyde de cerium (utilise comme traceur inactif de l'oxyde de plutonium) subissent une degradation thermique (pyrolyse et combustion). L'emission d'aerosols radioactifs est caracterisee par la quantite totale de contaminants emis, la cinetique de l'emission et la granulometrie des aerosols. Dans un second temps, la mise au point d'une procedure experimentale a permis la realisation d'essais a grande echelle dans des conditions se rapprochant de celles d'un incendie. Au terme de cette etude les outils experimentaux proposes permettent d'envisager l'application a d'autres scenarios

Ce travail a pour theme l'etude des densites d'etats aux interfaces profondes. Les methodes utilisees sont, pour l'analyse des etats de valence, la spectroscopie d'emission x induite par electrons et pour l'analyse des etats de conductibilite les spectroscopies d'isochromate. Les etats de valence a l'interface entre deux metaux, ni-al et entre deux semiconducteurs iii-v gaas-algaas sont etudiees et les modifications observees par rapport aux materiaux massifs sont discutees en liaison avec les calculs de densite d'etats existants. Le melange d'etats entre atomes voisins est clairement mis en evidence ainsi que la presence de defauts a l'interface des semiconducteurs iii-v. La decroissance radiative d'un exciton de cur al1s est observee pour les semiconducteurs etudies. La variation d'energie du pic excitonique est discutee en liaison avec les modifications de densites d'etats. Pour un super reseau gaas-al#0#,#3 ga#0#,#7as une localisation partielle des etats de l'aluminium est observee. Elle traduit le caractere bidimensionnel de ce systeme. La spectroscopie d'isochromate caracteristique appliquee aux systemes ag-si et ag-sio#2-si a permis de mettre en evidence une couche de quelques nanometres de compose situee a une interface profonde. Les spectres d'isochromates obtenus pour d'autres composes montrent que ce type de spectroscopie peut etre utilisee de maniere tres generale pour l'etude des etats de conductibilite des surfaces et des interfaces

El analisis de GoldVarb confirma que los hablantes mexiquenses mantienen la funcion tradicional del presente perfecto y el preterito mientras los madrilenos tienden a extender el presente perfecto hacia el pasado, cumpliendo con funciones anteriormente del preterito. En el habla portena, el preterito tiende a extenderse hacia el presente, dejando que el presente perfecto pierda funciones al preterito. Los resultados son comparables con estudios previos, demostrando que el blog puede ser considerado valido como un medio para estudiar el habla vernacula.

Streszczenie:

La rouille jaune est une maladie du ble qui apparait sous la forme de pustules jaunes sur les feuilles. Elle est provoquee par le champignon biotrophe puccinia stniformis. Ce parasite peut engendrer des pertes allant jusqu'a 40 q/ha. Afin de lutter efficacement contre ce parasite, l'agriculteur peut traiter ses cultures avec des triazoles. Mais s'il cherche a restreindre le cout des intrants et diminuer les risques de pollution, il devra cultiver des varietes de ble offrant un bon niveau de resistance a ce pathogene. Pour ce faire, de nombreuses varietes presentant un bon niveau de resistance a la rouille jaune comme pernel, renan, roazon, eureka, brigadier ont ete creees a partir d'un geniteur commun (vpm1) qui possede un tres bon niveau de resistance. Ce travail consiste a caracteriser les genes de resistance des varietes pernel et renan et a les assigner a un chromosome afin de trouver des marqueurs moleculaires utilisables en selection. La variete pernel ne possede qu'un seul gene majeur de resistance de stade plantule (yr17) alors que la variete renan en possede deux (yrx et yr17) ainsi que des genes mineurs. Le gene yr17 appartient a la meme introgression issue d'ae ventricosa que les genes de resistance a la rouille brune (lr37) et a la rouille noire (sr38). Trois types de marqueurs moleculaires (rapd, scar et rflp) lies au gene yr17 ont ete trouves. Ces marqueurs permettent de reconnaitre les plantes qui possedent ce gene de resistance sans effectuer de test pathologique et facilite par la meme, la selection precoce de genotypes. Le gene yrx et les genes mineurs sont des genes de resistance qui ne s'expriment qu'au stade adulte. Malgre le test de 728 amorces rapd avec la methode bsa, aucun marqueur lie au gene yr17 n'a ete identifie. Le gene yrx a ete assigne au chromosome 5a, par une analyse monosomique. Le gene yrx apporte un facteur de resistance durable et il devra etre cumuler a d'autres genes de resistance pour eviter son contournement.

Dans le cadre de la caracterisation de biomarqueurs de pollution, des cyprinides ont ete exposes 14 j. A des concentrations subletales de cu ou de procymidone, deux fongicides frequemment employes en viticulture. L'hepatotoxicite du metal et du pesticide est revelee par le developpement des lyses hepatocytaires et la presence d'hepatocytes en degenerescence. Cependant la plus grande part du parenchyme hepatique est compose d'hepatocytes basophiles montrant des caracteres ultrastructuraux de cellule au metabolisme accru (developpement de la taille du noyau, du reticulum endoplasmique granulaire et du chondriome). La reponse globale du foie est adaptative tout au long de l'exposition chez les danios et, uniquement les premiers jours, chez les gardons. Cela est confirme par le developpement des systemes de detoxications (mts, cyt p-450, b5, activite erod) et chez les poissons exposes au cu par l'accroissement du contenu en proteines totales, des defenses antioxydatives et du metabolisme de phase ii (catalase, gst, grd, gsh+gssg). A plus long terme, chez les gardons, les reponses (ultra)structurales et biochimiques signent une degenerescence hepatique (aggravations des alterations hepatocytaires, reduction des activites enzymatiques, du contenu en proteines totales et en cytochromes). Lorsque les poissons sont replaces 14 ou 20 j. En eau saine la depuration hepatique du cuivre est faible tandis qu'il ne persiste que des traces de procymidone. Dans les deux cas, les poissons presentent un accroissement du nombre des hepatocytes basophiles correle avec un nouveau developpement des systemes de detoxication qui signe la reversibilite des processus pathologiques induits. L'amplitude et la nature des reponses hepatique induites, montrent qu'elles pourraient etre utilisees comme biomarqueurs de pollution dans les milieux naturels contamines par ces polluants.

La mobilite des elements potentiellement toxiques presents dans un residu ultime solidifie/stabilise constitue un des criteres essentiels d'evaluation de l'impact de ces materiaux sur l'environnement. Le concept de mobilite doit etre envisage dans le cas du stockage des dechets, sous son double aspect : 1 - passage des elements de la phase solide dans la solution porale, 2 - transfert des elements de la solution porale dans le systeme de pores ou de fissures ou l'eau s'ecoule par gravite et qui existe au sein du materiau stocke. La qualification des dechets solidifies/stabilises concerne essentiellement la premiere etape. Pour cela on se propose de realiser des cinetiques de liberation dans des conditions qui sont proches de celles du milieu naturel. Cette approche consiste en l'etude experimentale du passage des elements de la phase solide a la solution porale, le lessivat d'alteration mais aussi de la phase solide, le reliquat d'alteration. Plusieurs etapes ont ete mises en evidence lors du processus d'alteration : aux temps courts -dissolution rapide des sels qui entraine la creation d'une nouvelle classe de pores de 10000 nm aux temps longs -alteration du materiau dans sa globalite qui se traduit par une redistribution des elements au sein du materiau et a des neoformations en peripherie de l'echantillon, -alteration des phases les moins labiles les csh. Ces phases contiennent 90% des elements potentiellement toxiques. De plus grace a la notion de temps equivalent reprise dans ce travail, il est possible de donner un caractere previsionnel aux resultats. On peut en effet a partir des experiences de laboratoire estimer la vitesse des processus d'alteration dans le milieu naturel c'est a dire evaluer la mobilite des elements au cours du temps. Le fait de pouvoir acceder au concept de mobilite permet de generaliser notre approche a d'autres materiaux qui peuvent etre a l'origine de contamination des eaux souterraines.

Ce travail decrit la synthese de nouveaux derives d'acides amines portant le motif tetrahydropyrimidine presents dans certains siderophores bacteriens. Il decrit egalement une voie de synthese nouvelle de la pyocheline, siderophore de type hydroxyphenylthiazolinyl-thiazolidine excrete par pseudomonas aeruginosa et burkholderia cepacia. Cette voie a ete ensuite appliquee a la synthese d'un analogue amine de la pyocheline, l'amino-5 pyocheline, permettant l'acces a des analogues photoactivables de la pyocheline envisages dans l'etude du mecanisme de transport du fer pyocheline-dependant. La premiere partie se rapporte donc a la synthese de differentes tetrahydropyrimidines. Celles-ci sont obtenues apres condensation de l'acide diamino-2,4 butyrique avec divers iminoethers d'acides amines proteges tels que la glycine, la serine ou la tyrosine. Ainsi la glycyltetrahydropyrimidine qui a permis de mettre au point la reaction de condensation a ete synthetisee sans epimerisation du centre asymetrique c-4. Dans le cas de la serine, le centre asymetrique c-8 s'epimerise par contre tres facilement. Neanmoins il est possible de preparer les seryl-tetrahydropyrimidine avec un taux d'epimerisation de centre asymetrique c-8 inferieur a 13% en utilisant des conditions de reaction tres strictes. Ces memes conditions de reaction ont permis d'obtenir les derives de la tyrosine sans aucune racemisation. Dans une deuxieme partie, une nouvelle voie de synthese de la pyocheline et de la benzyloxycarbonylamino-5 pyocheline est decrite. Ces siderophores sont obtenus par condensation de la (r) n-methylcysteine avec les (hydroxyaryl)-2 formyl-4 thiazolines correspondantes. Ces aldehydes ont ete prepares par reduction des hydroxamates correspondants avec l'hydrure d'aluminium et de lithium. L'ensemble de ces reactions conduit a un melange de quatre diastereoisomeres de la pyocheline avec un bon rendement apres condensation avec la (r) n-methylcysteine

Streszczenie:

In this report, we examine how digitalization influences the roles, structures and responsibilities of headquarters (HQs). We draw on 67 survey responses from top managers in corporate, divisional, and regional HQs located in Denmark and find that digitalization is expected to fundamentally change how HQs will operate. The vast majority of study participants spot a wide variety of opportunities arising from HQ digitalization and particularly highlight the potential for increased value creation as compared to cost savings. Enabled by better and timelier information for decision-making, HQs will improve their value-creating activities and will simultaneously involve themselves more in their subunits' businesses. At the same time, HQ managers see potential for efficiency gains through digitalization resulting in slightly smaller HQs and reduced overhead costs. Additionally, HQ managers will also be affected by digitalization through a rise in data-driven decision-making (as opposed to intuition) and personal accountability. Nonetheless, digitalization also entails a multitude of challenges. In this vein, over half of the HQs recognize that they lack not only a clear understanding of how digitalization will affect their HQ, but also crucial resources and capabilities for the digital future, such as digital talent and know-how. Overall, we show that the expectations towards and preparedness to adapt to digitalization differ across HQ types, industries, and organizational levels.

Streszczenie:

La fita principal d'aquesta tesi doctoral és oferir un estudi històric i comparatiu dels verbs de tercera radical dèbil en hebreu bíblic masorètic i mostrar, en aquells casos que pugui ser possible, l'origen etimològic d'aquest determinatiu radical sufixat a l'arrel verbal protosemítica. S'ha pretès, doncs, reconstruir etimològicament aquestes arrels verbals protosemítiques i detectar-ne morfològica i semànticament el determinatiu radical.

Aquesta tesi doctoral es divideix en dues parts principals i que a la vegada es complementen. La primera (§§1-5) va encaminada a explicar, des d'un punt de vista històric, l'origen i la formació de les arrels verbals semítiques, uns capítols que ens han semblat imprescindibles per poder dur a terme la segona part de la nostra recerca.

La segona (§§6 i 7) se centra bàsicament en l'estudi etimològic i comparatiu dels verba tertiae infirmae de l'hebreu bíblic masorètic per una banda (§6) i en la catalogació etimològica d'aquests verbs per l'altra (§7).

Les reconstruccions etimològiques s'han basat en el testimoni de les llengües semítiques més antigues documentades, en el funcionament intern d'aquest tipus de verbs de cada llengua i, cas que l'arrel verbal pugui ser remuntada a l'àmbit camito-semita, en el testimoni de les llengües afro-asiàtiques.

Les llengües semítiques que hem utilitat per realitzar el comentari són les antigues, en concret, les llengües epigràfiques nord-occidentals (i.e., hebreu epigràfic, arameu antic i oficial, fenici, etc.), l'ugarític, l'arameu antic, el bíblic i el rabínic, el siríac, l'accadi, l'antic sudaràbic epigràfic (sabeu), l'àrab clàssic i el geez.

Aquesta part comparativa ha estat imprescindible per arribar a conclusions de caràcter etimològic. En la part comparativa, doncs, hem volgut oferir sempre els paral·lels semítics del verb tertiae infirmae així com també les formes còncaves o de primera dèbil, les pll i les reduplicades que hi poguessin estar emparentades, així com també els substantius.

En el capítol següent (§7) oferim la catalogació etimològica de tots aquests verbs per donar-li una visió de conjunt. El darrer capítol de la nostra tesi se centra, doncs, en les conclusions argumentals i etimològiques que hem fet derivar de l'estudi etimològic dels verba tertiae infirmae (v") de l'hebreu bíblic masorètic realitzat en el capítol anterior.

La detecció morfològica d'aquests sufixos radicals ha estat un pas important per a entendre històricament la formació i l'estructura de l'arrel verbal protosemítica (i afroasiàtica). Els resultats que s'han obtingut d'aquest estudi han estat molt satisfactoris i interessants, perquè ajuden a definir des d'un punt de vista històric l'estructura de l'arrel protosemítica i afroasiàtica.
The aim of this doctoral dissertation is to offer an etymological and comparative study of the third weak radical verbs (*y and *w) in Proto-Semitic and to show, in those cases where it would be possible, the etymological origin of the root-determinative suffixed to the Semitic verbal root.

This doctoral thesis can be divided into two parts. The first one (§1-5) explains from a historical point of view the origin and formation of the verbal (and nominal) roots in Semitic. The second part (§§ 6 and 7) centres basically on the etymological and comparative study of masoretic biblical Hebrew tertiae infirmae.

The etymological and reconstructive work has been based fundamentally on the comparative study of the Semitic languages. The comparative task of this dissertation has always offered the parallel Semitic forms of weak verbs (tertiae infirmae, secundae infirmae, primae infirmae, secundae geminatae (type pll) and the reduplicated ones (type plpl) that could be in contact with the third radical *y or *w verbs.

The Semitic languages that are used to reconstruct the Proto-Semitic system are the most ancient: Akkadian, Ugaritic, Old Epigraphic South Arabic (Sabaean dialect), Classical Arabic, Geˁez (Ethiopic), north-western epigraphic languages, Hebrew (biblical and rabbinic), Aramaic (biblical and rabbinic) and Syriac.

It is interesting to mention that the morphological and semantical identification of this root-determinative has been an important step to understand the historical formation of the verbal root in Proto-Semitic. The results obtained in this project have been very satisfactory and interesting for our discipline, as a tool to define from a historical point of view the structure of the Proto-Semitic and Afro-Asiatic verbal and nominal root.

La presence d'autoanticorps a des taux eleves dans le serum des patients est l'une des caracteristiques des maladies autoimmunes. Parmi ces autoanticorps, les anticorps anti-histones sont reveles au cours de differentes maladies autoimmunes non specifiques d'organes telles que le lupus erythemateux dissemine, la polyarthrite rhumatoide et l'arthrite chronique juvenile. Nous avons particulierement etudie l'activite d'autoanticorps anti-histones notamment a l'aide de peptides synthetiques et nous avons montre que 1) l'origine des anticorps anti-histones serait differente selon la maladie concernee puisque ces anticorps sont diriges contre des regions differentes des histones; 2) dans le lupus erythemateux dissemine, ces anticorps sont codes par des genes pouvant appartenir a differentes familles germinales; 3) l'activite anti-histone parfois portee par des anticorps de type facteurs rhumatoides (anticorps multireactifs) est reliee a des sites distincts de ceux liant le fe et l'ig sur l'anticorps. D'autres anticorps specifiques d'un antigene mitochondrial correspondant a la dihydrolipoamide acetyltransferase (e2) du complexe pyruvate deshydrogenase de la chaine respiratoire ont ete mis en evidence au cours de differentes maladies hepatiques autoimmunes specifiques d'organes comme la cirrhose biliaire primitive. Nous avons montrer que les anticorps anti-e2 produits au cours de cette maladie sont diriges contre un epitope conformationnel constitue par la sequence 167-184 de e2 sur laquelle une molecule d'acide lipoique (cofacteur de e2) est lie de facon covalente

Nesta pesquisa, procuramos descrever os diversos usos do particípio presente nas comédias de Plauto (séc. II a. C.), à luz de alguns postulados da Linguística Funcional, em sua vertente norte-americana. Propomos uma associação entre noções linguísticas explicitadas nos textos dos autores latinos e conceitos próprios de nosso suporte teórico: as concepções de uso, variação e mudança discutidas pelas correntes teóricas modernas já estavam presentes nos manuais de retórica e de gramática antigos. Constatamos que o particípio era interpretado, de acordo com pensamento antigo, como uma classe de palavras distinta das demais, por participar ao mesmo tempo da natureza do verbo e do adjetivo. Antes mesmo da análise dos dados, indicamos diversos apontamentos acerca do emprego do particípio presente, pautados em compêndios gramaticais modernos, com o objetivo de contrastar tais informações com usos encontrados no texto do comediógrafo. Em um recorte sincrônico, observamos os particípios sempre levando em consideração o seu contexto de uso. Coletamos os exemplos nas 20 comédias, e com base neles, propomos quatro padrões funcionais: a) particípio presente com função verbal: b) particípio presente com função própria; c) particípio presente com função adjetiva; e) particípio presente com função circunstancial. Com base nesses padrões, comprovamos a nossas hipóteses iniciais de que o particípio possui níveis escalares de significação de acordo com o seu contexto de aparição e de que tais níveis escalares partem da categoria do verbo para a categoria do adjetivo
In this research, we intend to describe various uses of the present participle in the comedies of Plautus (centuries. III-II. B.C.), under the view of some postulates of Functional Linguistics in its North American line. We propose an association between linguistic concepts explained in the texts of Latin authors and concepts of our theoretical support: the concepts of use, variation and change discussed by modern scholars were already present in the ancient manuals of rhetoric and grammar. We note that the participle was interpreted, according to ancient thought, as a word class distinct of the others, participating at the same time the nature of the verb and adjective. Even before the data analysis, we indicated several notes about the use of the present participle, guided by modern grammatical textbooks, in order to contrast the information with uses found in the comedy writer text. In a synchronic cut, we observe the participles always taking into account their context of use. We collect the samples in the 21 comedies, and based on them, we propose four functional standards: a) present participle with verbal function: b) present participle having individual functions; c) present participle with adjectival function; e) present participle with circumstantial function. Based on these patterns, we proved to our initial hypothesis that the participle has scalar levels of meaning, according to their appearance of context, and that such scalar levels range from the category of the verb for the category of adjective

Seated at tables of four, over four hundred women aged 55-95 years old unfold tablecloths of yellow, red, and black. With their choreographed and synchronized gesturing hands, they mimic traditional Euro-American quilt patterns. This performance, titled The Crystal Quilt, was produced by Los Angeles-based artist Suzanne Lacy in 1987 as the culminating work to the two-year long, statewide initiative Whisper Minnesota (1985-1987). There is a continued resonance of the quilt in Lacy’s oeuvre, as The Crystal Quilt was the third project to reference quilts and quilt making. The first project, Evalina and I: Crimes, Quilts, Art (1975-78), and a smaller commemorative project (1980), employed tactile quilting projects instead of the conceptual quilt arrangement that Lacy would incorporate in 1987. The formal and historical attributes of this textile practice have been largely ignored in contemporary scholarship on the artist, thus raising the question of how this very specific medium encouraged her artistic and activist agenda. The primary focus of this thesis is an exploration of how Lacy mediates these two approaches, one of feminism and the other inspired by conceptual artist Allan Kaprow, through the medium of the quilt. Neither Lacy’s quilt works nor the use of craft during the second wave feminist movement has been sufficiently analyzed within craft scholarship. The thesis thus centers on the historical labor of quilting, its pedagogical and political aspects, the cross generational connection of feminism since 1987, and finally, the impact it currently has on quilt scholarship.

Les travaux presentes dans ce memoire ont ete conduits dans le but d'etudier la toxicite de produits phytosanitaires utilises dans le vignoble champenois (cuivre, diuron, folpel) pour un organisme non-cible, une plante aquatique flottante, la lentille d'eau lemna minor. Nous nous proposions par ailleurs de rechercher des biomarqueurs d'exposition et d'effet chez cet organisme vegetal qui permettraient de detecter la pollution des eaux et les effets biologiques dont elle est responsable. Notre attention a porte plus particulierement sur la modulation des defenses antioxydantes de l. Minor par les trois toxiques modeles dans un premier temps puis par des effluents agricoles dans une deuxieme phase de validation de la methode. Nous avons montre que le diuron et le cuivre sont fortement toxiques pour l. Minor alors que le folpel l'est beaucoup moins. En depit d'un antagonisme d'action entre le metal et l'herbicide, la presence simultanee de ces deux toxiques dans le milieu represente un accroissement du risque ecotoxicologique potentiel par rapport a une contamination unique. Le folpel ne modifie ni la toxicite du cuivre ni celle du diuron. Les intoxications de l. Minor realisees en conditions controlees avec les trois composes et des effluents d'origine agricole ont revele que les defenses antioxydantes de cet organisme sont, de par leur inductibilite, ou inhibition, et leur sensibilite, susceptibles d'etre utilisees comme biomarqueurs d'exposition et d'effet a des toxiques. Parmi ces defenses, les antioxydants cellulaires (glutathion et ascorbate) et trois enzymes (cat, g-pod, gst) sont les plus interessantes. Les modalites de tests standards proposees sont des intoxications de 24 h pour la mesure des activites enzymatiques et 48 h pour les antioxydants. L'existence de relations dose-effet entre les reponses biochimiques et les concentrations en toxiques de l'eau indiquent que l'intensite des reponses pourrait permettre une semi-quantification de celle du stress subi par l'organisme.

Streszczenie:

During the last decades, most of the studies based on climate change effects on vegetation physiology have focused on upland forests and species at their border of distribution, since, in both conditions, species are highly affected by water scarcity. Although few studies have focused on water availability effects on riparian vegetation, these species could be extremely affected by water scarcity as they are usually found in wet environments and they may not have enough ecophysiological controls to cope with prolonged drought periods. Moreover, riparian zones are considered hotspots of nitrogen (N) processes. These ecotones can reduce part of the N loads received from adjacent ecosystems before they reach the stream, mainly via denitrification and vegetation uptake. In Mediterranean regions, where shallow organic soil layers are disconnected from groundwater, denitrification process is limited by the weak anoxic conditions on riparian forests soils. There, vegetation uptake becomes the main driver for N removal in Mediterranean riparian zones. Climate change effects on riparian vegetation may cascade down and modify this well-known capacity to remove N from riparian zones. The findings from two Mediterranean riparian forests in La Tordera catchment showed that riparian tree species are already experiencing the effects of drought periods in the Mediterranean region. Quercus robur species, typically found in mid-European floodplains, is already experiencing tree growth decline at its southernmost distribution range edge. On the other hand, riparian tree species at Mediterranean forests showed high dependence on soil water availability during summer, obtaining more than 80% of the water transpired from the vadose zone. Phreatophitic species, Alnus glutinosa and Populus nigra, took up water from the groundwater compartment during spring but soil water was their main water source during summer. A. glutinosa did not present ecophysiological controls to avoid drought situations, while P. nigra increased its iWUE during dry years. Fraxinus excelsior was cohabiting with both species in the riparian forest. This species, located far away from the stream channel, was more depending on soil water availability and did not present any ecophysiological mechanism to cope with summer drought. Conversely, the N-fixing invasive species Robinia pseudoacacia, which was co-occurring all across the riparian forest, showed high plasticity to cope with different water availability conditions. Additionally, the findings obtained from the effects of riparian vegetation on water and N fluxes highlighted the high spatial heterogeneity of Mediterranean riparian forests within relatively small distances (~25 m). The studied Mediterranean riparian forest showed a remarkable spatial heterogeneity on water availability, with groundwater levels increasing from the near-stream zone (~0.6m deep) to the hillslope edge (~2.2m deep). Shallow groundwater tables enhanced the connectivity between vadose zone and groundwater at the near-stream zone, allowing greater transpiration and N uptake rates compared to the hillslope edge. Conversely, denitrification rates were generally low across all the riparian area due to water limitation and its weak anoxic conditions. Nevertheless, these soil conditions promote respiration rates all across the riparian forest soil, and thus, riparian soils emitted large CO2 fluxes. Finally, simulation based on climate change projections suggested a future increase in soil N concentrations as well as a reduction of the effective N-removal area of this riparian zones. The feasible substitution of autochthonous species by the already present R. pseudoacacia may homogenize soil N availability across the riparian area but would not increase the future soil N availability. Overall, our findings highlight the spatial heterogeneity of Mediterranean riparian zones and the need to better evaluate spatio-temporal processes to understand their mechanisms. N retention in Mediterranean riparian soils occur mainly by vegetation uptake. Yet, future climate projections may exacerbate water scarcity problems, inhibiting denitrification rates and reducing vegetation uptake. Therefore, these results challenge the well-accepted capacity to reduce N loads reaching the stream, and suggest that Mediterranean riparian soils can become a potential source of N to adjacent aquatic ecosystems in the future.
Durant les darreres dècades, la majoria d'estudis sobre els efectes del canvi climàtic en la vegetació s'han centrat en boscos d'alta muntanya amb un gradient latitudinal i espècies en els seus límits de distribució geogràfica, ja que, en ambdues situacions, els individus poden trobar-se afectades per l'escassetat d'aigua. Tot i que pocs estudis s'han centrat en els efectes de disponibilitat d'aigua en la vegetació de ribera, aquestes espècies podrien veure's extremadament afectades per l'escassetat d'aigua, donat que normalment es troben en ambients humits i poden no disposar de controls ecofisiològics suficients per afrontar períodes sequera prolongada. D'altra banda, les zones de ribera es consideren hotspots dels processos del nitrogen (N). Aquests ecotons poden reduir part de les càrregues N que arriben dels ecosistemes adjacents abans d'arribar al riu, principalment a través de la desnitrificació i l'absorció per part de la vegetació. A les regions mediterrànies, on els horitzons orgànics dels sòls orgànics queden desconnectats de l'aigua del freàtic, el procés de desnitrificació està limitat per les baixes condicions anòxiques dels sòls de ribera. Així doncs, l'absorció de N per part de la vegetació es converteix en el principal procés de retenció de N a les zones de ribera mediterrànies. Els efectes del canvi climàtic en la vegetació de ribera poden també modificar aquesta capacitat d'eliminar N de les zones de ribera. Els resultats obtinguts en dos boscos de ribera mediterranis de la conca de La Tordera mostren que les espècies arbòries de ribera estan experimentant els efectes de la sequera a la regió mediterrània. Quercus robur, que normalment es troba en planes d'inundació d'Europa central, estan experimentant un declivi en el creixement anual dels individus en el seu límit de distribució geogràfica més meridional. D'altra banda, les espècies arbòries dels boscos de ribera mediterranis una elevada dependència a la disponibilitat d'aigua del sòl durant el període d'estiu, obtenint més del 80% de l'aigua transpirada a la zona de no saturada del sòl. Les espècies freatòfiles, Alnus glutinosa i Populus nigra, obtenen l'aigua principalment del freàtic durant la primavera, però el sòl no saturat és la principal font d'obtenció d'aigua durant l'estiu. A. glutinosa no presenta controls ecofisiològics per evitar les situacions de sequera, mentre que P. nigra augmenta la seva iWUE durant els anys secs. Fraxinus excelsior conviu amb ambdues espècies al bosc de ribera. Aquesta espècie, situada a les zones allunyades del llit del riu, presenta una forta dependència a la disponibilitat d'aigua del sòl tot i no tenir mecanismes ecofisiològics per afrontar la sequera estival. Contràriament, l'espècie invasora fixadora de N, Robinia pseudoacacia, es troba distribuida al llarg de tot el bosc de ribera i presenta una gran plasticitat per fer front a les diferents condicions de disponibilitat d'aigua. A més, els resultats obtinguts sobre els efectes de la vegetació de ribera sobre els fluxos d'aigua i N han destacat la gran heterogeneïtat espacial dels boscos de ribera mediterranis en distàncies relativament curtes (~ 25 m). El bosc de ribera mediterrània estudiat mostra una notable heterogeneïtat espacial en la disponibilitat d'aigua, amb nivells freàtics decreixents des de la zona pròxima a la llera del riu (~ 0,6 m de profunditat) fins a les zones més allunyades (~ 2,2 m de profunditat). Els nivells freàtics més superficials faciliten l'intercanvi entre la zona saturada i no saturada del sòl, permetent també una major transpiració de la vegetació i absorció de N per part d'aquesta a les zones més pròximes a la llera del riu. Per contra, les taxes de desnitrificació són baixes a tota la zona de ribera degut a la limitació del sòl de ribera en quant a contingut d'aigua del sòl, i la conseqüent anòxia que afavoreix l'activitat dels bacteris desnitrificadors. No obstant això, aquestes condicions aeròbiques del sòl, amb relativa humitat, promouen altes taxes de respiració a tot el sòl forestal de ribera, i la conseqüent elevada emissió de CO2. Finalment, la simulació basada en les projeccions del canvi climàtic suggereixen un augment futur de les concentracions del N al sòl, així com una reducció de l'àrea de ribera capaç de retenir N de forma efectiva. La possible substitució de les espècies autòctones per la invasora R. pseudoacacia podria homogeneïtzar la disponibilitat de N del sòl al llarg de la zona de ribera, però no augmentaria la futura disponibilitat de N del sòl. Així doncs, els nostres resultats destaquen l'heterogeneïtat espacial de les zones de ribera mediterrànies i la necessitat d'avaluar els processos a escala espaciotemporal per comprendre'ls millor. La retenció de N en sòls de ribera mediterranis es produeix principalment per l'absorció d'aquest per part de la vegetació. No obstant, les projeccions climàtiques poden agreujar els problemes d'escassetat d'aigua, inhibint les taxes de desnitrificació i reduint l'absorció de N per part de la vegetació. Per tant, aquests resultats qüestionen la capacitat de les zones de ribera mediterrànies de reduir les càrregues de N que arriben als rius, així com suggereixen que els sòls de ribera mediterranis poden esdevenir una font potencial de N als ecosistemes aquàtics adjacents en el futur.

La technique de culture cellulaire nous a permis d'obtenir des epithelia derives de la plupart des segments du nephron de lapin; le tubule contourne proximal (tcp), l'anse de henle, le tubule contourne distal brillant (tcdb) et le tubule collecteur. Nous avons montre par l'etude de leurs caracteristiques morphologiques, biochimiques et electrophysiologiques que l'essentiel des proprietes connues des cellules originales etaient exprimees en culture. L'identification precise des differents types cellulaires en culture a ete faite a l'aide d'anticorps monoclonaux (acm) et les canaux ioniques presents dans la membrane apicale des cellules ont ete etudies par la technique du patch clamp. Sur le tcp, deux types de canaux potassium et un canal cationique aspecifique ont ete caracterises. Sur l'anse de henle, un canal potassium de grande conductance (145 ps) et un canal cationique aspecifique ont ete observes. Sur le tcdb, un canal sodium, un canal cationique aspecifique, un canal potassium et un canal chlore ont ete mis en evidence. Sur le tubule collecteur, les cellules intercalaires de type i ont ete identifiees grace a un acm, et un canal cationique aspecifique a ete caracterise sur leur membrane apicale

Neste trabalho, buscamos analisar, Ã luz do Sociofuncionalismo, a variaÃÃo entre futuro do presente, futuro perifrÃstico (IR + INFINITIVO) e presente com valor de futuro, considerando condicionamentos linguÃsticos e extralinguÃsticos a partir de dados extraÃdos da mÃdia cearense impressa. Para tanto, testamos trÃs grupos de fatores linguÃsticos formais (extensÃo do vocÃbulo, polaridade e pessoa do discurso), trÃs grupos de fatores linguÃsticos discursivos (marca de futuridade, distanciamento temporal e tipo de verbo) e trÃs grupos extralinguÃsticos (editoria, jornal e origem do dado). Nosso corpus foi coletado a partir de dez exemplares de cada um dos quatro jornais que, atualmente, compÃem a mÃdia cearense impressa, sÃo eles: DiÃrio do Nordeste, O Povo, O Estado CE e Aqui CE. Nos quarenta periÃdicos coletados, encontramos 2.184 dados referente Ã variÃvel futuro do presente, dos quais, 1181 apresentados sob a forma de futuro do presente sintÃtico, 706 de presente e 297 de perÃfrase. Nossos dados foram submetidos ao programa computacional estatÃstico Goldvarb X, que gerou os pesos relativos que serviram de alicerce para nossa descriÃÃo e anÃlise dos dados. O programa apontou que o futuro do presente Ã condicionado pelos grupos: tipo de verbo, extensÃo do vocÃbulo, editoria, jornal, origem, distanciamento temporal e pessoa do discurso. A perÃfrase, por sua vez, Ã condicionada pelos grupos: tipo de verbo, distanciamento temporal, extensÃo do vocÃbulo, pessoa do discurso e polaridade. Por fim, o presente do indicativo Ã condicionado pelos grupos tipo de verbo, extensÃo do vocÃbulo, distanciamento temporal, editoria, origem, jornal e polaridade. As trÃs variantes ocorrem em todas as editorias, dos quatro jornais. Entretanto, o nÃmero de dados da variante conservadora Ã maior que o somatÃrio dos dados das duas variantes inovadoras. A pesquisa tambÃm buscou discutir o princÃpio da marcaÃÃo. Todos os grupos extralinguÃsticos atenderam ao princÃpio da marcaÃÃo, com exceÃÃo da origem. Os grupos de fatores linguÃsticos, por sua vez, negaram o princÃpio da marcaÃÃo e atenderam ao princÃpio da expressividade estilÃstica. ConcluÃmos, nos grupos extralinguÃsticos, que a tendÃncia Ã que as formas mais marcadas ocorram em contextos mais marcados e as menos marcadas em contextos menos marcados. JÃ em relaÃÃo aos grupos extralinguÃsticos, o comportamento Ã de busca por um equilÃbrio discursivo contextual.
In this paper, we analyze, in the light of Socialfunctionalism, the variation between the present future, periphrastic future (IR + INFINITIVE) and present with future value, considering linguistic and extralinguistic conditions from the data extracted from printed media in the state of CearÃ . To do so, we tested three groups of formal linguistic factors ( word extension, subject of speech, and polarity), three groups of discursive linguistic factors (point of futurity, temporal distancing, and type of verb) and three extralinguistic groups (editorial, newspaper and source the data). Our corpus was collected from ten copies of each of the four newspapers that currently make up the CearÃ printed media, they are: DiÃrio do Nordeste, O Povo, O Estado, and Aqui CE. In the forty periodicals collected we found 2184 data regarding the variable present future, of which, 1181 are presented in the form of synthetic present future, 706 of present, and 297 of periphrasis. Our data were subjected to the statistical computer program Goldvarb X, which spawned the relative weights that served as the foundation for our description and data analysis. The program pointed out that the present future is conditioned by the groups: type of verb, word extension, editorial, newspaper, origin, temporal distancing, subject speech, and polarity. The periphrasis, on the other hand, is conditioned by the groups: type of verb, temporal distancing, Extension of the word, subject speech and Polarity. Finally, the indicative present is conditioned by the type of verb groups, word extension, temporal distancing, editorial, Origin, Newspapers and Polarity. The three variants occur in all the editorials of the four newspapers. However, the number of the conservative variable is greater than the sum of the data from the two innovative variants. All extralinguistic groups attended the principle of marking , except the one of the origin. The groups of linguistic factors , in turn , denied the principle of marking and attended the principle of stylistic expressiveness. We conclude , in extralinguistic groups , the trend is that the more marked forms occur in more marked contexts and less marked in less marked contexts. In relation to extralinguistic groups, the behavior is the seek for a contextual discourse balance.

Grande parte das gramáticas tradicionais normativas faz uma diferenciação bem marcada entre os modos verbais Indicativo e Subjuntivo: enquanto se considera o Indicativo o modo da certeza, atribui-se ao Subjuntivo o valor da incerteza, da hipótese. Todavia, há casos em que essa distinção não se manifesta tão segura, visto que em orações factuais nem sempre o Indicativo é utilizado, assim como os dois modos, por vezes, podem expressar falta de certeza (PERINI, 2009; 2010). Além disso, CAMARA JR. (2009: 280-281) assevera que “em português, como nas demais línguas românicas, o subjuntivo sofreu a interferência do indicativo e só aparece em determinados tipos frasais, por uma servidão gramatical”. É usado em contextos bem específicos, dentre os quais se destacam: oração independente depois do advérbio de dúvida talvez; oração integrante subordinada a verbos de significação volitiva ou optativa; oração adverbial que desenvolve uma concessividade, uma finalidade ou uma causalidade. Neste trabalho, sob a ótica da Sociolinguística Variacionista, investigou-se a variação entre o presente do indicativo e o presente do subjuntivo, nos referidos contextos sintáticos em que a prescrição gramatical preconiza o uso obrigatório do modo verbal subjuntivo. Assim, analisam-se casos em que, em maior ou menor grau, a expectativa de emprego do subjuntivo é contrariada, gerando enunciados de aceitabilidade duvidosa no âmbito da variante de prestígio do português. Para a consecução dos fins da pesquisa, realizaram-se testes sociolinguísticos de percepção e de produção com turmas iniciais e finais do segundo segmento do Ensino Fundamental e 3º ano do Ensino Médio, em seis escolas públicas e privadas dos municípios de Niterói e Itaboraí e analisaram-se produções textuais dos discentes dessas mesmas escolas. Consideraram-se estatisticamente relevantes as variáveis extralinguísticas tipo de escola, escolaridade e cidade e as variáveis linguísticas contexto sintático e pessoa gramatical com significância estatística. Constatou-se também que a variável contexto sintático pode ser descrita em um continuum, no qual as orações adverbiais de finalidade apresentam maior frequência de uso do subjuntivo, enquanto no polo oposto localizam-se as orações adverbiais de causalidade. Por fim, percebeu-se que a 1ª pessoa gramatical motiva o uso do indicativo, assim como alunos do 6º ano de escolaridade tendem a usar mais frequentemente esse modo verbal nos contextos de uso estudados
Many of the traditional normative grammars stablish a well-marked differentiation between Indicative and Subjunctive verbal modes. As the Indicative is considered the mode of certainty, the value of uncertainty, or hypothesis, is attributed to the Subjunctive. However, there are cases where this distinction doesn’t show itself as safe, as in factual clauses the Indicative is not always used, as well as the two modes, sometimes, can express lack of certainty (PERINI, 2009; 2010). In addition, CAMARA JR. (2009: 280-281) states that “in Portuguese, as in other Romanic languages, the subjunctive suffered the interference of the indicative and appears only in certain types of sentences, by a grammatical servitude”. It is used in very specific contexts, among which are: independent clause after the adverb of doubt perhaps; integral clause subordinated to verbs with volitional or optative signification; adverbial clause that develops a concession, a purpose or causality. In this work, from the perspective of variationist sociolinguistics, we investigated the variation between the present tense and the present subjunctive, in those syntactic contexts in which the grammatical prescription recognize to the compulsory use of the verbal mode subjunctive. Thus, we analyzed cases where, to a greater or lesser extent, the expected use of subjunctive is counteracted, creating statements of questionable acceptability under the scope of Portuguese prestigious variant. To the consecution that work, Sociolinguistic tests of perception and production are carried out with initial and final classes of primary education and the second cycle of secondary education in six schools – both the public and private types – in the cities of Niteroi and Itaborai and we analyzed textual productions of the students of those schools. We also consider the extra linguistic variables type of school, schooling and city and as linguistic variables, we considered syntactic context and grammatical person with statistical significance. We also contacted that the variable syntactic context can be described in a continuum which adverbial clauses of purpose had more signal subjunctive use, while at the opposite pole are located the adverbial clauses of causality. Finally, it is clear that the 1 st grammatical person motivates the use of the indicative, as well as students from 6th grade tend to use more often this way in the use of verbal contexts we studied

Este trabalho de pesquisa toma como ponto de partida um trabalho artístico de minha autoria, onde existiu uma apropriação de imagens banais de jornais, livros, revistas, que foram parcialmente apagadas, eliminadas, para fazer surgir novos desenhos e pinturas posteriores. Este processo foi metaforicamente comparado a dois importantes termos, um utilizado em biologia, a deiscência e outro em medicina, a prosopagnosia. Relacionaram-se estes termos com outros não menos importantes para todo o processo teórico-prático, tais como a intuição, a respiração e o momento presente. Desta forma, tentou-se, mas agora através de palavras, recriar as mesmas condições que fizeram surgir as imagens, para recebê-las melhor e ao mesmo tempo, impulsionar a criação de novos desenhos, novas pinturas, novas imagens; ABSTRACT: This research work takes as its starting point for an artistic work of my authorship, where there was an appropriation of banal images of newspapers, books, magazines, which were partially erased, removed, to bring up new drawings and paintings later. This process is metaphorically compared to the two important terms used in a biology, dehiscence and another in medicine, prosopagnosia. Terms were related with others no less important for all practical process, such as intuition, breath and the present moment. Thus, we tried to, but now with words, to recreate the same conditions that have brought the images to receive them better and at the same time, promote the creation of new designs, new paintings, new images.
