Texto completoPassados, 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?

Texto completoWriting 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.

Gueu, Soumahoro. "Elimination des acides humiques presents dans les eaux par adsorption et/ou photocatalyse". Thesis, Université de Lorraine, 2019. http://www.theses.fr/2019LORR0043/document.
Texto completoWater 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

Texto completoWhen 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

Texto completoThis 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.

Bofill, Mas Silvia. "Detecció i caracterització dels poliomavirus presents en la població a partir de mostres ambientals". Doctoral thesis, Universitat de Barcelona, 2003. http://hdl.handle.net/10803/2384.
Texto completoEntre 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).

Texto completoSAMP8 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.

Texto completoLes 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.

Texto completoLe 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.

Texto completoConfronting 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.

Texto completoThe 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.

Texto completoLa 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.

Texto completoWith 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.

Texto completoCom 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.

Texto completoS'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.

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.

Texto completoAquesta 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 geez.
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.

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

Texto completoDurant 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.

Texto completoNeste trabalho, buscamos analisar, à 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 à 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 à condicionado pelos grupos: tipo de verbo, extensÃo do vocÃbulo, editoria, jornal, origem, distanciamento temporal e pessoa do discurso. A perÃfrase, por sua vez, à condicionada pelos grupos: tipo de verbo, distanciamento temporal, extensÃo do vocÃbulo, pessoa do discurso e polaridade. Por fim, o presente do indicativo à 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 à 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 à que as formas mais marcadas ocorram em contextos mais marcados e as menos marcadas em contextos menos marcados. Jà em relaÃÃo aos grupos extralinguÃsticos, o comportamento à 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 Cearà . 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 Cearà 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
