A principal patologia ? o granuloma, uma resposta imune contra os ant?genos secretados pelos ovos do parasito principalmente no f?gado e intestinos. Estes ant?genos est?o crucialmente envolvidos na modula??o das respostas imunol?gica celular e humoral do hospedeiro e podem estar envolvidos na estrat?gia de passagem do ovo atrav?s da mucosa intestinal. Este trabalho teve origem nos resultados de um experimento realizado por Candida Fagundes Teixeira do Grupo de Parasitologia Biom?dica da PUCRS, cujas tentativas de se obter anticorpos do ovo que interagissem com part?culas paramagn?ticas, revelaram alguma dificuldade em obter n?veis elevados de anticorpos contra a superf?cie do ovo. O objetivo principal do presente trabalho foi verificar a produ??o de anticorpos contra a superf?cie do ovo de Schistosoma mansoni. O S. mansoni, isolado Esteio, foi mantido em laborat?rio atrav?s de passagens em Biomphalaria glabrata e camundongos da cepa Swiss. Os vermes foram recuperados, lavados com tamp?o e utilizados para a produ??o de ant?geno sol?vel de membrana de vermes adultos. Os ovos foram coletados de fezes humanas infectadas e utilizados para a imuniza??o de camundongos e produ??o de ant?genos secretados pelo ovo (SEA). Os grupos experimentais foram divididos em 4 grupos com 6 camundongos cada, da seguinte forma: grupo 1 imunizado com solu??o salina 0,9%; grupo 2 imunizado com ovos sonicados e adjuvante; grupo 3 imunizado com ovos sonicados sem adjuvante e grupo 4 imunizado com ovos inteiros. Atrav?s da t?cnica de ELISA e imunofluoresc?ncia indireta foi verificada reatividade na imuniza??o com ovos sonicados, e n?o foi verificada reatividade na imuniza??o com ovos inteiros. A abordagem sist?mica e complexa da intera??o parasito-hospedeiro ? uma proposta interessante de estudo e permanece aberta para futuras investiga??es que poder?o auxiliar na compreens?o e tratamento da patogenia.

Ce mémoire amorce une critique sur la problématique des procédés figuratifs à propos des tableaux niçois matissiens (1916-1930), qui se présentent à nous comme les apories d'une pratique picturale vue comme embrayage d'une toute nouvelle figuration. Cette recherche fait le point sur le mouvement des conflits non-résolus, où le repérage de contradictions, de nouvelles mises en rapport, en dehors du discours dominant des oeuvres, sert la transformation du conformisme de notre vision. Le premier chapitre clarifie la notion du retour à l'ordre. Le second analyse les odalisques comme connotant les avants possibles de la figure. Et le troisième est une critique de la théorie réifiée de la valeur esthétique. Dans cette perspective, ce travail cherche à éclaircir la praxis matissienne de la figuration comme catégorie possible de la peinture.<br>Montréal Trigonix inc. 2018

Such characteristics possibly result in high amounts of this protein in the soils, as well as a reduced rate of decomposition, and it is considered an important fraction of soil organic matter. Humic Substances (HS) have been recognized for a long time as the organic component most widely distributed on the planet, present both in terrestrial and aquatic environments. They are formed from chemical and biological degradation of residues from plants, animal and microbial activity. Although with some progress on structural aspects of glomalin and humic substances, there are few studies that describe their structural differences using a spectroscopic and chemometric approach. To search for answers for these questions, having as a reference the existing environmental and ecological relationships, this study aimed to confirm the structural relationship (differences and similarities) between the glomalin and humic substances obtained from different sources, through the isolation and purification of soil protein fractions related to glomalin (Glo), and the humic substances (HSs) fractions from different environments and composted materials; characterizing glomalin and humic substances obtained by chemical, physical and spectroscopic techniques (elemental composition, UV-vis, FTIR, 13 C CP-MAS RMN, EMS), and by using chemometric techniques (Unscrambler? X 10.3).<br>A glomalina ? considerada como uma glicoprote?na hidrof?bica, termoest?vel e recalcitrante produzida pelos Fungos Micorr?zicos Arbusculares (FMA). Tais caracter?sticas possivelmente implicam em altas quantidades desta prote?na nos solos bem como uma reduzida taxa de decomposi??o, sendo considerada como uma importante fra??o da mat?ria org?nica do solo. As Subst?ncias H?micas (SH) t?m sido reconhecidas durante muito tempo como o componente org?nico mais amplamente distribu?do no planeta, presentes tanto em ambientes terrestres quanto aqu?ticos. Elas s?o formadas a partir da degrada??o qu?mica e biol?gica de res?duos de plantas, animais e da atividade microbiana. Embora existam alguns avan?os sobre aspectos estruturais da glomalina e as subst?ncias h?micas, ainda s?o escassos os estudos que descrevem as suas diferen?as estruturais utilizando uma abordagem espectrosc?pica e quimiom?trica. Buscando encontrar respostas a estes questionamentos, assumindo como base de estudo a rela??o ambiental e ecol?gica existente, este estudo tem como objetivo confirmar a rela??o estrutural (diferen?as e semelhan?as) existente entre a glomalina e as substancias h?micas de diferentes origens, atrav?s do isolamento e purifica??o das fra??es da prote?na do solo relacionada ? glomalina (Glo) e as fra??es de subst?ncias h?micas (SHs) de diferentes ambientes e materiais compostados; caracterizando a glomalina e as subst?ncias h?micas obtidas atrav?s de t?cnicas qu?micas, f?sicas e espectrosc?picas (composi??o elementar, UV-vis, FTIR, CP-MAS 13C RMN, MEV) e atrav?s da utiliza??o de t?cnicas quimiom?tricas (Unscrambler?

Esta dissertação estabelece um \"Estado da arte\" sobre os Games a partir do banco de teses e dissertações da CAPES entre os anos de 1987 e 2010, e tem como principal objetivo mapear e discutir a produção acadêmica brasileira cujo objeto de estudo ou tema central são estes recursos tecnológicos, em seu estatuto comunicacional, lúdico e educacional. A problematização da pesquisa propõe a discussão sobre a forma em que os games são entendidos nessas práticas educacionais, meios de comunicação na sua mediação tecnológica com os distintos setores do conhecimento. A hipótese levantada diz respeito a se o Game, como objeto de pesquisa, pode se constituir como uma estratégia de comunicação relevante para formação, no que se refere aos estímulos e motivações considerados em tais processos. Portanto, a principal contribuição deste trabalho consiste em estabelecer uma base informacional que responda aos aspectos e dimensões que vêm sendo destacadas e privilegiadas no período assinalado e nos lugares em que têm sido produzidas. A metodologia subjacente toma como princípio uma análise bibliográfica e documental, assim como uma exaustiva análise quantitativa dos dados oferecidos. Deste modo, a estrutura da dissertação contempla um primeiro capítulo que aborda o surgimento do game no contexto da \"sociedade em rede\", contextualizada na era digital da informação em tempos de globalização, assim como, no conceito de interatividade mediada pelo computador diante da eminência da tecnologia no mercado brasileiro. Em um segundo capítulo trata-se do game a partir das diferentes classificações tomando como referência principal suas finalidades no âmbito social, psicológico e comunicacional. Por fim, o terceiro capítulo trata especificamente do \"estado da arte\" da pesquisa dos Games no Brasil. Configurando assim, a sistematização e categorização dos resultados: como crítica aos meios de comunicação digital; à relação entre games e saúde físico-motora; aos elementos constitutivos do jogo; à sua inserção nos processos educacionais; e, à conectividade com as redes mundiais. Por fim, discute-se a produção científica stricto sensu no Brasil que cruza o Game com a educação.<br>This dissertation establishes a \"state of the art\" on the Games from the database of theses and dissertations from CAPES between the years 1987 and 2010, and has as main objective to map and discuss the Brazilian academic production, whose object of study or theme is these technological resources, their status in communication, entertainment and education. The problematic of research proposes a discussion about the way games are understood in these educational practices, the media in its technological mediation with the distinct sectors of knowledge. The hypothesis relates to the game, as a research subject can be constituted as a communication strategy relevant to training, with regard to incentives and motivations considered in such cases. Therefore, the main contribution of this paper is to establish an information base that responds to the aspects and dimensions that have been highlighted and privileged in the indicated period and in places that have been produced. The principle underlying methodology takes as a literature review and documentary, as well as a comprehensive quantitative analysis of the data provided. Thereby, the structure of the dissertation includes a first chapter that discusses the rise of the game in the context of the \"network society\", contextualized in the digital age of information in times of globalization, as well as the concept of computer mediated interactivity on the brink technology in the Brazilian market. In a second chapter covers up the game from different classifications with reference to their main purposes in the social, psychological and communicational. Finally, the third chapter deals specifically with the \"state of the art\" research of the Games in Brazil. Setting thus the systematization and categorization of results such as criticism of digital media, the relationship between games and health-physical fitness; the constituent elements of the game, its inclusion in the educational processes, and connectivity to global networks. Finally, we discuss the strictly scientific production in Brazil which crosses the Game with education.

In this sense, this research proposes a study on gender sorted, motivated by the desire of understanding how the text incorporates traces of change and how to keep its constituents over time, in order to point out what are its characteristic traits. Our analysis is centered on the newspaper s section called classificados of Tribuna do Norte, state of Rio Grande do Norte, between the XX and XXI centuries. From the survey data a descriptive and analytical analysis was performed with a corpus of 250 listings, divided between the years 1951-2010. Based on a diachronic analysis, we also seek to investigate the macro-structural aspects of gender and microstructural compositional elements from the opportunities section that originated the Caderno de Classificados . For this reason, this approach has focused on particular Roman German Philology, especially in the works of Coseriu (1980) and Kabatek (2006). The analysis revealed that since its inception in Brazil, the classificados have fixed constituent elements, such as the use of "sell" and "rent" in the title or introduction, but also shows traces of change in the closure of the text, and especially with regard to the division of classificados by area of interest, that in the newspaper called Tribuna do Norte started in the Opportunities section<br>O texto, ao se realizar em diferentes esferas lingu?sticas, em muitos aspectos absorve os processos mut?veis pelos quais a l?ngua passa em decorr?ncia das mudan?as s?cio-hist?ricas.

Notre travail s’intéresse à l’immigration tunisienne dans les Alpes-Maritimes. Il s’agit de s’intéresser aux réalités humaines, économiques et sociales qui assurent au fait migratoire une indépendance plus ou moins complète à l’égard des pouvoirs publics. La première partie est consacrée à l’identification du fait migratoire en Tunisie. Nous observons d’une part, une économie qui n’arrive pas à offrir des opportunités d’emploi suffisantes pour résorber un chômage endémique, d’autre part, l’appel d’une France en pleine croissance économique fournit de nouvelles perspectives à des milliers de Tunisiens. Les pouvoirs publics élaborent des cadres législatifs pour maîtriser les flux migratoires. Ces dispositifs n’arrivent pas à remplir les tâches qui leurs incombent et se réduisent à accompagner les déplacements humains. Dans la deuxième partie, nous nous sommes intéressés aux évolutions et aux modalités des arrivées des Tunisiens dans les Alpes-Maritimes. L’intérêt des Tunisiens pour ce département s’explique aussi bien par ses caractéristiques administratives et économiques que par le fonctionnement interne des réseaux et des filières migratoires. Dans la troisième partie, nous nous penchons sur la question de l’insertion urbaine, économique et sociale. Celle-ci correspond à la fois aux possibilités qu’offre le département en matière de logement et aux opportunités d’emploi que fournit la structure économique dans les Alpes-Maritimes. Appartenant à une structure sociale régie par des affinités familiales, claniques, locales et nationales, l’immigré tunisien arrive à solutionner les problèmes structurels de logement et à surmonter les difficultés conjoncturelles de l’emploi<br>Our research aims at investigating the following question: how Tunisian immigration to the Alpes-Maritimes department does mange to overcome the legal immigration restrictions set by Tunisian and French government to control the migration flow? ” To answer this question, we intend to explore the human, economic and social conditions in which the migration trajectories are embedded. Firstly, in order to refine our research question, we highlight the historical context of Tunisian immigration in France (1956-1984). During this period, Tunisian economy couldn’t offer job opportunities to fight against unemployment. At the same time, the rapid growth of French economy was very tempting for thousands of Tunisians. On both sides of the Mediterranean Sea, public authorities strive to build a legal framework that help controlling migration flow. Yet, these regulations weren’t effective and couldn’t master Tunisian immigration movement. Secondly, we pay attention to the evolution of strategies adopted by Tunisian to reach Alpes-Maritimes department. The interest of Tunisians in this region could be explained by the administrative and economic attractiveness of the department as well as the implementation of Tunisian social networks in this region. Finally, we will consider the question of urban, economic and social insertion. We focus on opportunities provided by the Alpes Maritimes department in terms of employment as well as housing. Similarly, we analyse how the membership of a clan, a social or a familial network could help Tunisian immigrants in facing different kind of difficulties

Overexpression of the transporter proteins P-glycoprotein (Pgp) and multidrug resistance-associated protein (MRP) confer resistance to the treatment these leukemias. OBJECTIVE: To analyze the expression of the Gpp and MRP1 in patients with AML by flow cytometry (FC) and to determine the correlation between expression and demographic and also clinical and laboratorial variables. METHODS: Bone marrow and peripheral blood samples from 346 patients with a diagnosis of AML were assessed for the expression of Pgp and MRP1 by FC. RESULTS: The expression of Pgp and MRP1 was found in 111 (32.1%) and 133 (38.4%) patients, respectively, with greater prevalence in older patients and lower in adolescents, observing also a high incidence in patients with refractory disease, recurrence and secondary in comparison with the cases of de novo AML. Regarding the laboratory findings, we observed a higher correlation statistically significant between the expression of Pgp and MRP1 in AML CD34+ and FAB AML M7, M5A and M2 and lower the M3 subtype, not observed statistically significant correlation between the phenotype MDR and other laboratory data such with hemoglobin, leukocyte count, platelet count, aberrant expression of lymphoid antigens (CD2, CD7 and CD19) and clinical signs related to the disease. CONCLUSIONS: The results showed that the detection of MDR phenotype by flow cytometry can be a molecular marker for prognosis independent patients diagnosed with AML.

The experiment was conducted in the area of EscolaT?cnicaAgr?colaEstadualRei Alberto I, located in the Watershed Barrac?o dos Mendes, Municipality of NovaFriburgo, mountainous region on the state of Rio de Janeiro at an altitude of 1,065m. The experimental design was a randomized complete block design with four treatments: black oat, lupines albus, consortium and weeds, with four replications each, totaling 16 plots in the first stage of work, experiment 1. On the experiment 2, the plots were subdivided into two management systems, mechanical, where the plants were mowed and chemical, which occurred application of glyphosate herbicide, for the deposition of the straws on the ground. On the first part, productivity of green manure was evaluated, as well as the accumulation of nutrients and the epigaeous fauna associated to vegetation. The second part, after the management of the green manure, aimed the evaluation of mass loss of plant residues, epigaeous fauna and associated soil macrofauna. The main results showed that the lupine, single or consortium obtained satisfactory productivity, both in terms of biomass and the amount of accumulated nutrients, presenting potential for use in the mountainous region of Rio de Janeiro. The loss of mass of the residues was affected by the use of herbicide. The community of epigaeous fauna was not a good indicator because it didn?t suffer significant changes before or after the green manure management. The colembolas population was negatively afected by the herbicide. The soil macrofauna was more sensitive to the diferent forms of management, and the reduction of the density soil organisms could be observed up to 10 times when the plants were sprayed with herbicide. It was also noted the reduction on the macrofauna diversity. There was no difference in the chemical composition of the soil due to different covers and forms of management<br>Visando obter informa??es que ap?iem a proposi??o de manejos de gest?o da biodiversidade, que viabilizem sistemas de produ??o sustent?veis e garantam a qualidade dos recursos naturais, este estudo pretende colaborar com o aumento da produtividade agr?cola com base no uso da aduba??o verde, de forma sustent?vel. Nesse sentido, o presente trabalho teve como objetivo avaliar o comportamento dos adubos verdes de inverno tremo?o-branco, aveia-preta e do cons?rcio entre os dois, em ambiente de montanha, e a influ?ncia do herbicida na taxa de decomposi??o das palhadas dessas plantas e na diversidade e abund?ncia da fauna do solo. O experimento de campo foi conduzido na ?rea da Escola T?cnica Agr?cola Estadual Rei Alberto I, localizada na Microbacia do Barrac?o dos Mendes, Munic?pio de Nova Friburgo, Regi?o Serrana do Estado do Rio de Janeiro, a uma altitude de 1.065 m. O Delineamento experimental adotado foi o de blocos casualizados, com quatro tratamentos: aveia-preta, tremo?o-branco, cons?rcio e plantas espont?neas, com quatro repeti??es cada, totalizando 16 parcelas na primeira etapa do trabalho, etapa I. Na etapa II, as parcelas foram subdivididas em duas formas de manejo, mec?nico, onde as plantas foram ro?adas, e qu?mico, onde ocorreu aplica??o do herbicida glifosato, para a deposi??o das palhadas sobre o solo. Na etapa I, estudou-se a produtividade das plantas de cobertura, bem como o ac?mulo de nutrientes e a fauna ep?gea associada ?vegeta??o. Na segunda etapa, ap?s o manejo das plantas de cobertura, foi realizada a avalia??o da perda de massa dos res?duos vegetais, fauna ep?gea e macrofauna ed?fica associadas a esses res?duos. Como principais resultados, observou-se que o tremo?o, solteiro ou consorciado, obteve produtividade satisfat?ria, tanto em termos de fitomassa, quanto de quantidades de nutrientes acumulados, apresentando potencial para o uso na Regi?o Serrana do Rio de Janeiro. A perda de massa dos res?duos vegetais foi afetada com o uso de herbicida. A comunidade da fauna ep?gea n?o foi um bom indicador, pois n?o sofreu significativas modifica??es antes ou ap?s o manejo das plantas de cobertura. No entanto, as popula??es de col?mbolos foram afetadas negativamente pelo herbicida. J? a comunidade da macrofauna ed?fica se mostrou mais sens?vel ?s formas de manejo, sendo observada a redu??o da densidade dos organismos do solo ? metade e em at? 10 vezes, quando as plantas foram manejadas com herbicida. Observou-se tamb?m redu??o da diversidade da macrofauna. N?o houve diferen?a na composi??o qu?mica do solo em fun??o das diferentes coberturas e formas de manejo

The objective of this study was to generate pedotransfer functions (FPT) to assess the accuracy of previously published equations, applying them to predict soil bulk density (Bd) in organic soils from Brazil; to evaluate subsidence rate, and the variation of Bd and carbon of humic substances in Histosols over a period of one year; and to estimate stock and potential loss of carbon in Histosols from Rio de Janeiro State. For the first part of the study, there were used organic horizons, i.e., soil materials with total organic carbon (TOC) equal to or greater than 80 g kg-1 soil, totaling 280 horizons from different regions of Brazil. It was used the multiple linear regression technique and the equations were validated on independent data. There were tested 9 equations already published in the literature. The equations with better performance were the Hollis and FPT2, with R2 validation parameters of 0.48 and 0.49. When the clay fraction data is availlable, it is recommended to use the FPT1 equation; if there is no data on clay it is recommended the FPT2 and Hollis equations, which have only the TOC as a predictor variable. For the second part, a greenhouse experiment was carried out. For that, undisturbed samples were collected using PVC pipes, of two profiles of Organossolos Tiom?rficos, one in the neighborhood of Santa Cruz (SC Profile), city of Rio de Janeiro, and one in Mag? (Profile MG) municipality. There were evaluated 3 drainage levels, at 30, 60, and 100 cm deep, with 5 measuremts over time, being 0, 90, 180, 270, and 360 days (4 replicates). The MG profile presented the highest rates of subsidence, reaching 1.30 cm year-1 for the 100 cm drainage. Bd increased over time for both profiles, and the deeper drainage increased values in the SC profile. The deeper drainage favored the reduction of pH for both profiles. The TOC showed a decreasing trend over time. The values of carbon in the fulvic acid fraction (FAF), humic acid fraction (HAF), and humin fraction (HUM) showed no differences according to drainage levels. However, over time they showed high sensitivity to temperature changes, showing high levels of FAF and HAF at the end period and a consequent reduction in humin fraction. For the third and final section, there were used 43 soil profiles, where 18 of them did not have bulk density data, which were estimated by the FPTs. Comparisons between measured and estimated data groups was performed using the Wilcoxon test. The spatial distribution of the variables was performed using the IDW interpolation method. The average values of TOC was 228.0 g kg-1, Bd was 0.48 Mg m-3, the thickness of the profiles was 86 cm, the depth was 90 cm and the average stock TOC was 73.51 kg m-2. The spatialization showed qualitative differences for the variables in the different profile locations. The estimated TOC stock for the profiles form RJ State was 27,178,631.8 Mg. The estimated rates of loss were 10.87 kg m-2 for Histosols more recently drained and high TOC; of 7.16 kg m-2 for intermediate drained Histosols; and 1.46 kg m-2 for Histosols with longer time after drainage and low TOC. Soils with high TOC levels are more likely to have high losses TOC when disturbed.<br>Os Organossolos s?o uma importante fonte de estoque de carbono nos ambientes terrestres e possuem alta suscetibilidade ?s perdas de carbono quando perturbados. O objetivo do presente trabalho foi gerar equa??es, avaliar a acur?cia de equa??es j? publicadas, aplicando-as para a predi??o da densidade do solo (Ds) em solos org?nicos do Brasil; avaliar a taxa de subsid?ncia, a varia??o da Ds, e o carbono das subst?ncias h?micas em Organossolos ao longo do per?odo de um ano; e estimar o estoque e as potenciais perdas de carbono nos Organossolos do Estado do Rio de Janeiro. Para a primeira parte, trabalhou-se com horizontes org?nicos, i.e., materais de solo com teores de carbono org?nico total (COT) iguais ou maiores que 80 g kg-1 de solo, totalizando 280 horizontes em diferentes regi?es do Brasil. Foi empregada a t?cnica de regress?o linear m?ltipla e as equa??es foram validadas sobre dados independentes. Foram testadas 9 equa??es j? publicadas na literatura. As equa??es com melhor desempenho foram FPT2 e Hollis, com par?metros de valida??o R2 de 0,48 e 0,49. Em casos onde os teores de argila estejam quantificados, recomenda-se a equa??o FPT1, e na sua aus?ncia recomenda-se as equa??es FPT2 e Hollis, que possuem somente o COT como vari?vel preditora. Para a segunda parte, realizou-se um experimento em casa de vegeta??o. Foram coletadas amostras indeformadas em tubos de PVC, de dois perfis de Organossolo Tiom?rfico, sendo um no bairro Santa Cruz (Perfil SC), munic?pio de Rio de Janeiro, e outro no munic?pio de Mag? (Perfil MG). Foram avaliados 3 n?veis de drenagem, sendo de 30, 60, e 100 cm de profundidade, 5 avalia??es ao longo do tempo, sendo de 0, 90, 180, 270, e 360 dias (com 4 repeti??es). O perfil MG apresentou as maiores taxas de subsid?ncia, chegando a 1,30 cm ano-1 para a drenagem de 100 cm. A Ds aumentou ao longo do tempo para os dois perfis, e a drenagem mais profunda aumentou os valores no perfil SC. A drenagem mais profunda favoreceu a redu??o do pH para os dois perfis. Os teores de COT apresentaram tend?ncia de redu??o ao longo do tempo. Os valores de carbono da fra??o ?cido f?lvico (FAF), fra??o ?cido h?mico (FAH), e fra??o humina (HUM), n?o mostraram diferen?as de acordo com os n?veis de drenagem. No entanto, ao longo do tempo, apresentaram alta sensibilidade ?s varia??es de temperatura, mostrando elevados teores de FAF e FAH no per?odo final, e a consequente redu??o dos teores de HUM. Para a terceira e ?ltima parte do estudo, foram usados 43 perfis de Organossolos, sendo que 18 deles n?o apresentavam os dados de densidade do solo (Ds), os quais foram estimados por meio de FPTs. As compara??es entre os grupos de dados medidos e estimados foi feita pelo teste de Wilcoxon. A espacializa??o das vari?veis foi realizado atrav?s do m?todo de interpola??o IDW. Os valores m?dios de COT foi de 228,0 g kg-1, a Ds foi de 0,48 Mg m-3, a espessura dos perfis foi de 86 cm, a profundidade foi de 90 cm, e o estoque m?dio de COT foi de 73,51 kg m-2. A espacializa??o mostrou diferen?as qualitativas para as vari?veis nos diferentes locais. Foi estimado um estoque de COT de 27.178.631,8 Mg para os Organossolos do Estado do RJ. As taxas estimadas de perdas foram de 10,87 kg m-2 para Organossolos com drenagem mais recente e altos teores de COT; de 7,16 kg m-2 para Organossolos intermedi?rios; e 1,46 kg m-2 para Organossolos com menores teores de COT e longo tempo de drenagem. Solos com altos teores de COT est?o mais propensos a terem altas perdas de COT quando perturbados.

The embryonated eggs are released with the waste products of the definitive host and the infection settles in the snail by ingestion of these. After hatching, the miracidium, develop inside the snail two sporocysts generations, cercariae and metacercariae. The definitive host acquires infection by ingestion of parasitized snail. The present study was aimed to identify the action of the parasite on the kidney of pigeons, Columba livia, through histology, and the morphometry, morphology and ultrastructure using light microscopy, scanning electron and transmission of the egg, larval stages (miracidium , cercariae and metacercariae) and adult helminth P. bragai. The adults pigeons were obtained near the Central de Abastecimento do Estado do Rio de Janeiro S.A, Iraj?, Munic?pio do Rio de Janeiro. After parasitological examination in the laboratory, to check infection, the pigeons infected were necropsied to collect helminth and infected kidney. The pigeons were used as uninfected controls. The experimental protocols were approved by the ethics committee on research UFRRJ. Histopathology showed dilatation of the renal tubules, with mononuclear inflammatory cells, formation of papilliform structure projecting into the tubular lumen and metaplasia of the epithelium of the collecting tubule walls, from simple cubic in the tubules uninfected to pseudostratified in infected kidney with P. bragai. The eggs are elliptical, with operculum at the anterior end and a knot at the posterior end, abopercular region. The eggshell is rough and composed of three layers: inner, middle and outer with thicknesses and different electrondense. The miracidium is elongated, with terebratorium the anterior end and body covered with cilia. The cercariae have cylindrical body that tapers slightly in the posterior region. The tegument is rough, the oral sucker is subterminal, the acetabulum stands in the middle third of the body. Papillae were observed around the oral sucker. A similar rudimentary tail structure was observed in some cercariae. The metacercariae observed through histological sections visualized the oral sucker, acetabulum, scales and cyst that consist of three layers, inner, middle and outer, of different thicknesses. The presence of the layers was confirmed by visualization of histological sections of metacercariae in scanning electron microscopy. The adult parasite is elongated and flattened body with oral sucker, pharynx, vitelline glands extending to the region of cecal bifurcation and then the median region of the body. The genital pore visualized a structure that is everted the cirrus in rosette form. In the adult stage the tegument is covered with scales of various types; simple scales, with two, three, four, five and seven divisions, a characteristic that may contribute to ratify the taxonomic classification of the parasite.<br>Paratanaisia bragai ? um digen?tico que atinge a maturidade sexual nos ductos coletores de aves dom?sticas e silvestres, e para o desenvolvimento larval utiliza o molusco Subulina octona ou Leptinaria unilamellata. Os ovos embrionados s?o liberados com os produtos de excre??o do hospedeiro definitivo e a infec??o no molusco se estabelece pela ingest?o destes. Ap?s a eclos?o do mirac?dio, desenvolvem-se no interior do molusco duas gera??es de esporocistos, cerc?rias e metacerc?rias. O hospedeiro definitivo adquire a infec??o por ingest?o do molusco parasitado. O presente estudo teve como objetivos: verificar a a??o do parasito sobre o rim de pombos, Columba livia, atrav?s da an?lise histopatol?gica bem como analisar a morfometria, morfologia e ultraestrutura utilizando a microscopia de luz, eletr?nica de varredura e transmiss?o do ovo, est?gios larvais (mirac?dio, cerc?ria e metacerc?ria) e helminto adulto de P. bragai. Pombos adultos foram obtidos pr?ximos a Central de Abastecimento do Estado do Rio de Janeiro S.A, Iraj?, Munic?pio Rio de Janeiro. Ap?s exame coproparasitol?gico, no laborat?rio, para verifica??o da infec??o, os pombos infectados foram necropsiados para a coleta dos helmintos e do rim infectado. Os pombos n?o infectados foram utilizados como grupo controle. Os protocolos experimentais foram aprovados pela comiss?o de ?tica na pesquisa da UFRRJ. A an?lise histopatol?gica revelou dilata??o dos t?bulos renais, processo inflamat?rio com c?lulas mononucleadas, forma??o de estrutura papiliforme projetando-se para a luz tubular e metaplasia do epit?lio da parede do t?bulo coletor, de epit?lio c?bico simples nos t?bulos n?o infectados a pseudroestratificado nos rins infectados com P. bragai. Os ovos s?o el?pticos, com op?rculo na extremidade anterior e n? na extremidade posterior, regi?o abopercular. A casca apresenta-se ?spera e composta por tr?s camadas: interna, m?dia e externa de espessuras e eletrondensidades diferentes. O mirac?dio ? alongado, com terebratorium na extremidade anterior e corpo coberto por c?lios. As cerc?rias apresentam corpo cil?ndrico que se afunila ligeiramente na regi?o posterior. O tegumento ? rugoso, a ventosa oral ? subterminal, o acet?bulo destaca-se no ter?o m?dio do corpo. Papilas foram verificadas ao redor da ventosa oral. Uma estrutura semelhante ? cauda rudimentar foi observada em algumas cerc?rias. Nas metacerc?rias observadas atrav?s de cortes histol?gicos visualizou-se a ventosa oral, o acet?bulo, as escamas e cisto composto por tr?s camadas, interna, m?dia e externa, de espessuras diferentes. A presen?a das camadas foi confirmada na visualiza??o dos cortes histol?gicos das metacerc?rias na microscopia eletr?nica de varredura. O parasito adulto tem corpo alongado e achatado com ventosa oral, faringe, gl?ndulas vitelog?nicas extracecais que se prolongam anteriormente at? a regi?o de bifurca??o cecal e posteriormente a regi?o mediana do corpo. No poro genital visualiza-se uma estrutura evertida que ? o cirro em formato de roseta. No est?gio adulto o tegumento ? coberto por escamas de v?rios tipos; escamas simples, b?fidas, tr?fidas, com quatro, cinco e sete divis?es, caracter?stica que pode contribuir para ratificar a classifica??o taxon?mica do parasito.

Metteur en scène contemporain dont l’itinéraire personnel est une conséquence de la décentralisation théâtrale, Daniel Benoin tire sa force de création du passage de l’image mentale à sa concrétisation dans le spectacle vivant par l’hybridation de savoirs multiples et de techniques artistiques. Cette étude d’un destin particulier dans un rapport holiste avec l’art dramatique permet une théorisation du processus de création dans lequel un regard croisé entre phénoménologie et pragmatique confirme l’hypothèse d’une empreinte matérielle et stylistique. L’approche comparative d’un grand nombre de représentations et de l’ensemble des répétitions préalables à cinq spectacles (Wozzeck, La Cantatrice chauve, Faces, la reprise de La Cantatrice chauve, Le roman d’un trader) définira cette empreinte comme idiosyncrasique, formelle et originale, le tout commun à l’ensemble de l’œuvre observée. Ainsi, grâce aux concours de pré-images modulables et fécondes, les images mentales primordiales s’installent au cœur de la création et la vision onirique se révèle être l’essence même de la particularité artistique de ce metteur en scène. La recherche entreprise ouvre alors des perspectives renouvelées quant à l’esthétique et à la présence/absence de l’artiste dans des domaines élargis (cinéma, danse, peinture, photographie, musique, écriture)<br>Daniel Benoin, a contemporary stage director whose personal career was a consequence of theatrical decentralization, draws his creative strength from his ability to make mental images become concrete in live shows by using numerous knowledge and artistic techniques in a hybrid way. This project on a distinctive destiny in a holist connexion with Drama enables to theorize about the creation process in which a crossed look at phenomenology and pragmatism confirms the hypothesis of a material and stylistic imprint. The comparative approach of many performances and of all the preliminary rehearsals to five theatrical shows (Wozzeck, La Cantatrice chauve, Faces, the remake of La Cantatrice chauve, Le roman d'un trader) will eventually define this mark as an idiosyncratic, formal and original one, to be found in the whole work which was studied. Thus, thanks to the help of fertile and adjustable pre-images, essential mental images settle in the heart of creation and the oneiric vision turns out to be the very essence of the artistic particularity of this stage director. Therefore the research opens up renewed angles about the aesthetics and the presence/absence of the artist in enlarged fields (such as cinema, dancing, painting, photography, music, writing)

Thesis (MPhil (Journalism))--University of Stellenbosch, 2009.<br>There are certain images of war that are horrific, frightening and at the same time, due to an outstanding compositional structure, they are fascinating and do not allow its observers to keep their distance. This thesis examines three images of war that have often been described as icons of war photography. The images “children fleeing a napalm strike” by Nick Ut, “the falling soldier” by Robert Capa and Sam Nzima’s photograph of Hector Pieterson are historical reference images that came to represent the wars and conflicts in which they were taken. It has been examined that a number of different factors have an impact on a war photograph’s awareness level and its potential to commit itself to what is referred to as collective consciousness. Such factors are the aesthetical composition and outstanding formal elements in connection with the exact moment the photograph was taken, ethical implications or the forcefulness of the event itself. As it has been examined in this thesis, the three photographs have achieved iconic status due to different circumstances and criteria and they can be described as historical reference images representing the specific wars or conflicts. In this thesis an empirical study was conducted, questioning 660 students from Spain, South Africa and Vietnam about their awareness level regarding the three selected photographs. While the awareness level of the Spanish and the South African image was rather high in the countries of origin, they did not achieve such a high international awareness level as the Vietnamese photograph by Nick Ut, which turned out to be exceptionally well-known by all students questioned. Overall, findings suggest that the three selected icons of war photography have been anchored in collective memory.

This thesis is divided into two main parts. The first, comprising the three initial chapters, looks, in chapter one, at the specifically German origins of the Bildungsroman, its distinctive features, and the difficulties surrounding its transplantation into the literary contexts of other countries. Particular attention is paid to the ethical dimension of the genre, i.e. to the relation between the individual self and the exterior world, and how it affects individual formation. The focus then shifts to American literature, and the term 'narrative of initiation' is recommended as a credible alternative to 'Bildungsroman'. Allowing for similarities between them, it is none the less strongly suggested that the Bildungsroman of German origin and the American narrative of initiation should be seen as being intrinsically different, principally because of the different cultural backgrounds that shaped them. Several features of the theme of initiation are postulated as decisive factors in the discrepancies between the initiatory narrative and the Bildungsroman. Analysis of six texts - three of each literary tradition - follows, to provide support for the theoretical discussion of the terms introduced in chapter one. Three Bildungsromane are considered in the second chapter, namely Goethe's Wilhelm Meisters Lehrjahre, Stifter's Der Nachsommer and Keller's Der grune Heinrich, and three narratives of initiation in chapter three: Twain's The Adventures of Huckleberry Finn, Crane's The Red Badge of Courage and Anderson's Winesburg, Ohio. Their relevance to the tradition of German and American fiction as a whole and as precursors of Mann's Der Zauberberg and Hemingway's The Nick Adams Stories is considered. A direct comparison between Mann's and Hemingway's texts constitutes the second part of this thesis, wholly contained in chapter four. In addition to a comprehensive critical reading of both narratives, the contemporaneity of Der Zauberberg and The Nick Adams Stories is taken into account, and consequently special consideration is given to the texts' close relation with the cultural and historical realities of the early twentieth century, particularly the impact of the First World War. With the assistance of Jung's theories, an increased awareness of death and of the dark side of the psyche - though dealt with differently in both texts - is put forward as a significant factor in the deviation of Der Zauberberg and The Nick Adams Stories from the traditions of the Bildungsroman and of the narrative of initiation. This departure leads to a re-appraisal of the relation between the protagonists and their society, and to a new ethical attitude that presupposes different, more modem conceptions of what Bildung and initiation represent in the context of the early twentieth century. How and why they changed and if they survived as literary notions are questions this thesis attempts to answer.
