O presente estudo refere-se a uma Dissertação de Mestrado em Educação Ambiental (EA) a qual teve como objetivo estabelecer um diálogo em torno do conceito de nature-za a partir da análise das formas desse discurso veiculadas nas histórias em quadrinhos (HQs) do personagem Chico Bento e suas relações com as concepções presentes no campo de saber da EA. Com a intenção de problematizar a forma como as HQs, através do discurso de natureza, vêm contribuindo para pensarmos sobre EA, selecionaram-se HQs do Chico Bento publicadas entre os anos de 2009 e 2013 e que fazem referência à natureza. Apoiado em autores como Michel Foucault, Isabel Carvalho, Leandro Belina-so Guimarães, Maria Lúcia Castagna Wortmann, Mônica Meyer, Keith Thomas, Ray-mond Williams, entre outros, a pesquisa analisou as enunciações de natureza que com-puseram o corpus de análise desta investigação. O caminho metodológico selecionado para operar com o material empírico trata especificamente de algumas ferramentas da Análise do Discurso, a partir de Michel Foucault. Na análise do material posto em sus-penso, a pesquisa apontou para dois enunciados potentes, os quais vêm auxiliando na constituição do discurso de natureza por meio das HQs: a natureza constituída nos des-locamentos operados pelas diferenças culturais entre as realidades rural e urbana e um ideal romântico de natureza produzido pela visibilidade e enunciabilidade das HQs do Chico Bento. Com isso, evidenciou-se que as HQs analisadas entram na ordem do dis-curso verdadeiro no campo da EA. Sendo assim, ressalta-se a importância de atentarmos para os gibis e suas histórias, como um artefato cultural potente que vem nos auxiliando a olhar para o dispositivo da EA. Tal dispositivo interpelando-nos a constituir modos de ser e de viver, diante de saberes e verdades produzidas na e pela cultura, pois, diante dos significados travados por meio da cultura, vamos engendrando nossos modos de vida, bem como estabelecendo relações com o mundo em que vivemos.

Diverses œuvres de poésie moderne et contemporaine mettent en scène le rapport à l’écriture d’un sujet lyrique. Une telle problématique trouve une incarnation particulièrement intéressante dans l’œuvre de Patrice Desbiens, notamment dans certains de ses textes des années 1990 et 2000, où elle apparaît avec plus d’acuité. Pourtant, sa pratique auto-réflexive a fait l’objet de très peu de recherches. Afin d’éclairer le rapport qu’entretient Patrice Desbiens avec l’écriture et avec la poésie, ce mémoire s’intéresse à deux de ses textes, soit La fissure de la fiction (1997) et Désâmé, (2005) en accordant davantage d’espace au premier, que je considère comme un texte-charnière dans la production poétique de Desbiens. Dans un premier temps, mon travail présente ainsi la précarité qui caractérise le protagoniste de La fissure de la fiction et, sous un autre angle, le sujet lyrique de Désâmé. Dans cette optique, la figure du poète est étudiée dans La fissure de la fiction à la lumière de la reprise ironique du mythe de la malédiction littéraire et du sens que la réactualisation de ce mythe confère au personnage dans ce récit poétique. Dans un second temps, ce mémoire s’attache à montrer que la cohérence et la vraisemblance des univers mis en scène dans La fissure de la fiction et Désâmé sont minées. C’est à l’aune de ces analyses que peut ensuite être envisagé le rôle d’une poésie qui, en dernière instance, comporte malgré tout un caractère consolateur, en dépit ou en raison de l’esthétique du grotesque, tantôt comique, tantôt tragique, dans laquelle elle s’inscrit et que nous tâcherons de mettre en lumière.

The trees, hedgerows and woods are current configuration of the tree network in several ecological regions of the world. In Trás–os–Montes region, Northeast of Portugal, they are a traditional component of Terra fria landscape and they could be seen in several forms: scatter trees, fencerows, small woodlots, riparian buffer strips, among others. The extensive livestock systems in this region are based on a set of circuits across the landscape. In this practice, flocks interacts with these structures using them for different functions inducing an influence on the itineraries. Our purpose will be focused on the woody features of landscape regarding their configurations, abundance and spacial distribution; in order to examine how the grazing systems depends on the currency of these formations; particularly how species flocks behaviors are related on. Depending on spatial data, The investigation attain to compare the tree network within the agriculture matrix, to the grazed territory crossed by flocks. From the other side, the importance of spatial data on interpreting the issue by suggesting different parameter that may influence the circuits. The recognition of the pressure exerciced by the occurence of the woody structures on the grazed circuits is possible. We believe that the role of these woody structures features in supporting the tradicional silvopastoral systems has been sufficiently strong for change their distribution pattern.

La reciente aprobación de la ley Sinde en medio de un profundo y profuso debate público ha puesto de manifiesto que las ambiciones de las industrias de la cultura no están en sintonía con las de consumidores y ciudadanos. Se ha discutido la necesidad de reformular las leyes de propiedad intelectual, contraponiendo el derecho de los creadores a rentabilizar su trabajo con los derechos de los ciudadanos a la circulación de la cultura. Se hace necesario analizar los términos de este debate, además de los elementos ausentes en la discusión. La participación de los ciudadanos parece limitarse meramente a circular materiales culturales fuera de los cauces comerciales, pero no aparecen tematizadas las prácticas creativas, cada vez más comunes, que también infringen las leyes de propiedad intelectual. Los blogs mantenidos por fans sobre personajes de comic, las versiones dobladas de trailers de películas, el uso de samplers o mashups en la música popular, etc… Prácticas que implican la reelaboración creativa de textos preexistentes que cuestionan la centralidad del autor en su acepción clásica (la protegida por la legislación de derechos de autor). Proponemos contrastar los discursos en torno al derecho de los ciudadanos a la cultura que entienden este ejercicio como mero intercambio de archivos con las citadas prácticas intertextuales que suponen una forma de empoderamiento de las ciudadanos que discuten los límites de la creatividad y la originalidad. El análisis pretende dar algunas pistas para entender dos cuestiones: a) el alcance los derechos culturales de la ciudadanía democrática en la sociedad de la información y b) la necesidad de reelaborar las leyes de propiedad intelectual para dar cabida a las nuevas prácticas de la cultura digital.

Plague es un editor de archivos escritos en lenguajes de planificación como STRIPS y PDDL, que permite lanzar el algoritmo GrahPlan a partir de los archivos de dominio y problema editados y encontrar una solución al problema planteado. El objetivo del editor es eminentemente pedagógico: su uso es muy simple y viene con variados ejemplos de ambos lenguajes de planificación, de modo que el usuario pueda aprenderlos de forma paulatina. Además, la salida de la ejecución permite ir viendo paso a paso el desarrollo del algoritmo GraphPlan: los operadores que se van ejecutando, los no-ops que se han seguido, los mutex que se han aplicado en cada nivel y el tiempo empleado, además de la solución final al problema si se alcanza. El programa hace uso de dos utilidades que permiten compilar el código STRIPS o PDDL que son JavaGP y PDDL4J. Una vez ejecutado el problema de planificación, se obtiene la salida en pantalla y también se puede imprimir el problema completo incluida la solución. El objetivo ha sido crear un programa que permita al usuario editar rápidamente archivos STRIPS y PDDL, los pueda compilar velozmente y obtener el resultado en un solo sitio, con una salida mucho más clara, organizada y entendible y se evite el problema de tener que usar editores externos y una ventana de línea de comando para ejecutar GraphPlan. Plague is a text editor for files written in action languages, such as STRIPS and PDDL, which allows running the GraphPlan algorithm from the domain archives and edited problems, and finding a solution to the proposed problem. The goal of the editor is primarily for pedagogical purposes: it is simple to use and comes equipped with a variety of examples in both action languages, so that the user can gradually learn. In addition, as the editor runs it allows the user to observe the step by step development of the GraphPlan algorithm: the operators being executed, the no-ops that have been followed, the mutex applied at each level and the time spent, as well as the final answer to the problem, if reached. The program uses two utilities allowing the STRIPS or PDDL code to be compiled: JavaGP and PDDL4J. Once the planning problem has been executed, the result is shown on screen and the complete problem can also be printed, including the solution. The objective has been to create a program that allows the user to quickly edit STRIPS and PDDL archives, to compile them swiftly and obtain the solution in a single place, with a result that is clear, organised and understandable, thus avoiding the problem of having to use external editors and command prompts to execute GraphPlan.

Con el fin de aminorar retrasos por descementación de cualquier accesorio durante el tratamiento de Ortodoncia Lingual, se ha considerado que la fuerza de adhesión es muy importante, especialmente cuando está ubicada en las diferentes interfaces presentes entre el bracket y la resina del PAD; entre la resina del PAD y el cemento resinoso fotopolimerizable y entre este cemento y el esmalte dental. Por lo que este estudio se ha enfocado en determinar la resistencia adhesiva en la interfaz localizada entre la resina de la base del PAD y el cemento resinoso fotopolimerizable utilizando ácido fluorhídrico y óxido de aluminio como tratamiento de superficie previo a la cementación indirecta de la técnica lingual. MATERIALES Y METODOS: El tipo de estudio fue experimental "in vitro", con una muestra de 30 cuerpos de prueba hechos con resina Transbond XT, utilizando para su confección un blíster de brackets, se siguieron tres protocolos diferentes; G1 o grupo control sin ninguna preparación, G2 con aplicación de óxido de aluminio, 50 micrones durante 10 segundos en la superficie del cuerpo de prueba, G3 con aplicación de ácido fluorhídrico al 9% en la superficie del cuerpo de prueba durante 10 minutos. Previo al test de resistencia adhesiva, se realizó los cortes de precisión en cada cuerpo de prueba, obteniendo así 45 tiras de prueba, cada una de las muestras fue adherida a un porta muestra para la prueba de micro tracción, la misma que fue realizada con la máquina universal Mini-Instron modelo 5942, a una velocidad de deformación constante de 0.5 mm/min. Los datos fueron sometidos al test de Normalidad de residuos de Shapiro Wilk (p>0,05) y de LEVENE para el análisis de homogeneidad de las varianzas. La resistencia adhesiva fue comparada entre los grupos por medio del Análisis de Varianza (ANOVA) como factor único para el procesamiento de los datos. Para todos los análisis el nivel de significancia fue del 5% (p< 0,05) con un nivel de confianza del 95% (IC95%). Se consideró estadísticamente significativo valores por debajo de 0,05. RESULTADOS Y CONCLUSIONES: El resultado del test de ANOVA, reveló que el factor de tratamiento de superficie F(2,12)=2,52;p=0,12 no es significante, por lo tanto los diferentes tratamientos de superficie (óxido de aluminio y ácido fluorhídrico) utilizados son equivalentes al grupo control, indicando que no ejercen influencia de manera significativa en los valores de Resistencia Adhesiva (RA) en la preparación de la interfaz localizada entre la resina de la base del PAD y el cemento resinoso fotopolimerizable; concluyendo que se puede utilizar cualquier protocolo de tratamiento de superficie indicado en la presente investigación.

Purpose.: To analyze the levels of diadenosine tetraphosphate (Ap4A) and diadenosine pentaphosphate (Ap5A) in tears of subjects with Sjögren syndrome and to compare them with those in a control group. Methods.: Twelve subjects with a diagnosis of Sjögren syndrome and 20 healthy control subjects were invited to participate in the present study. Schirmer strips were used to measure tear secretion (Schirmer I test) and to collect tears. Ap4A and Ap5A were measured by high-pressure liquid chromatography (HPLC), and a dry eye questionnaire (DEQ) was used to evaluate dry eye symptomatology. Results.: The mean concentrations of Ap4A and Ap5A in the Sjögren syndrome group were 2.54 ± 1.02 and 26.13 ± 6.95 μM, respectively. This group of patients was divided in two subgroups: four patients with normal tear production and eight patients with low tear production. Concentrations of Ap4A, and Ap5A in patients with normal tear production (Schirmer test result, 12.3 ± 1.2 mm) were 0.47 ± 0.20 and 8.03 ± 3.27 μM, respectively. In the patients with low tear production (Schirmer test result, 1.0 ± 0.3 mm), the concentrations were 4.09 ± 1.36 and 39.51 ± 8.46 μM, respectively and in the control group, 0.13 ± 0.03 and 0.04 ± 0.02 μM, respectively. Conclusions.: Patients with Sjögren syndrome have abnormally elevated concentrations of diadenosine polyphosphates, indicating that these compounds could be used in the diagnosis of this disease.

Purpose To evaluate the possible use of soft contact lenses (CL) to improve the secretagogue role of diadenosine tetraphosphate (Ap4A) promoting tear secretion. Methods Two conventional hydrogel CL (Omafilcon A and Ocufilcon D) and two silicone hydrogel (SiH) CL (Comfilcon A and Balafilcon A) were used. Ap4A was loaded into the lenses by soaking in a 1 mM Ap4A solution during 12 h. In vitro experiments were performed by placing the lenses in multi-wells during 2 h containing 1 ml of ultrapure water. 100 μl aliquots were taken at time zero and every minute for the first 10 min, and then every 15 min. In vivo experiments were performed in New Zealand rabbits and both the dinucleotide release from SiH and tear secretion were measured by means of Schirmer strips and high-pressure liquid chromatography (HPLC) analysis. Results Ap4A in vitro release experiments in hydrogel CL presented a release time 50 (RT50) of 3.9 ± 0.2 min and 3.1 ± 0.1 min for the non-ionic and the ionic CL, respectively. SiH CL released also Ap4A with RT50 values of 5.1 ± 0.1 min for the non-ionic and 2.7 ± 0.1 min for the ionic CL. In vivo experiments with SiH CL showed RT50 values of 9.3 ± 0.2 min and 8.5 ± 0.2 min for the non-ionic and the ionic respectively. The non-ionic lens Ap4A release was able to induce tear secretion above baseline tear levels for almost 360 min. Conclusion The delivery of Ap4A is slower and the effect lasts longer with non-ionic lenses than ionic lenses.

Rhizobium freirei PRF 81 is employed in common bean commercial inoculants in Brazil, due to its outstanding efficiency in fixing nitrogen, competitiveness and tolerance to abiotic stresses. Among the environmental conditions faced by rhizobia in soils, acidity is perhaps the encountered most, especially in Brazil. So, we used proteomics based approaches to study the responses of PRF 81 to a low pH condition. R. freirei PRF 81 was grown in TY medium until exponential phase in two treatments: pH 6,8 and pH 4,8. Whole-cell proteins were extracted and separated by two-dimensional gel electrophoresis, using IPG-strips with pH range 4-7 and 12% polyacrilamide gels. The experiment was performed in triplicate. Protein spots were detected in the high-resolution digitized gel images and analyzed by Image Master 2D Platinum v 5.0 software. Relative volumes (%vol) of compared between the two conditions tested and were statistically evaluated (p ≤ 0.05). Even knowing that R. freirei PRF 81 can still grow in more acid conditions, pH 4.8 was chosen because didn´t affect significantly the bacterial growth kinetics, a factor that could compromise the analysis. Using a narrow pH range, the gel profiles displayed a better resolution and reprodutibility than using broader pH range. Spots were mostly concentrated between pH 5-7 and molecular masses between 17-95 kDa. From the six hundred well-defined spots analyzed, one hundred and sixty-three spots presented a significant change in % vol, indicating that the pH led to expressive changes in the proteome of R. freirei PRF 81. Of these, sixty-one were up-regulated and one hundred two was downregulated in pH 4.8 condition. Also, fourteen spots were only identified in the acid condition, while seven spots was exclusively detected in pH 6.8. Ninety-five differentially expressed spots and two exclusively detected in pH 4,8 were selected for Maldi-Tof identification. Together with the genome sequencing and the proteome analysis of heat stress, we will search for molecular determinants of PRF 81 related to capacity to adapt to stressful tropical conditions.

Increasing plant diversity in conventionally monoculture agrosystems has been promoted as a method to enhance beneficial arthropod density and efficacy, suppress herbivory and provide a range of ecosystem services. I investigated the pest suppressive potential and economic impact of plant diversification in organic field corn. The experiment consisted of two treatments, corn grown in monoculture (C) and bordered by strips of partridge pea (PP). Pest and natural enemy populations, corn damage, yield, and profits were compared among treatments. Natural enemy and herbivore arthropod populations were affected by treatment and distance from plot border. Corn damage due to pests was also affected by treatment and location, but did not significantly affect yield. Yield in monoculture plots was generally greater than in PP but did not result in greater profit. Pest and natural enemy arthropod abundances were elevated in partridge pea treatment borders, but these populations did not consistently diffuse into plot interiors. The potential causes and implications of findings are discussed.

This dissertation examines the fictional character Kitty Pryde from the X-Men comic book series during the tenure of writer Chris Claremont. Claremont's work on the character primarily involves the years 1980-1990, though a return to writing the character in the 2000s is also discussed when relevant. The thesis question revolves around the definition of the bildungsroman genre and whether Claremont's narrative arc for Kitty Pryde's character fulfills that definition. Jerome Hamilton Buckley's 1974 book Season of Youth: The Bildungsroman from Dickens to Golding is used as the primary authority for the bildungsroman genre, and more specifically a list of nine criteria that Buckley deems particularly key to the definition of the genre. Each of the nine criteria is looked at in depth, demonstrating where and how they can be found in the narrative, if at all. However, because Buckley's perspective and criteria come from a time of less diversity, examination from a feminist and minority perspective is also added with ideas from Rita Felski and Stella Bolaki. Combining Buckley's initial list of nine criteria with more modern criticism, these ideas are then used to analyze Kitty Pryde's narrative arc and to determine whether it can be seen as a bildungsroman. The findings support reading Claremont's narrative arc of the Kitty Pryde character as a bildungsroman. Three of Buckley's nine key themes are identified as particularly prevalent in the narrative: the search for a vocation, ordeal by love, and the conflict of generations. Three more key themes are found to be less prevalent but still clearly present: the search for a working philosophy, the larger society, and alienation. Because Buckley's definition for the bildungsroman genre requires the presence of six of his nine key themes, the presence of the aforementioned six thus validate the reading of the narrative as a bildungsroman. The text also provides some suggestions for finding the three least applicable key themes within the narrative, but because their presence is not necessary to fulfill the definition of the bildungsroman, they are not rigorously examined. In addition to fulfilling Buckley's key themes, the paper also discusses the more modern minority-oriented views. It is shown how the narrative can be read in terms of a journey to diverge from norms, as per Felski's ideas of the unique qualities of the specifically female bildungsroman. As Kitty Pryde's narrative can be shown to conform to the bildungsroman ideas of both Buckley and Felski, the thesis question is thus answered positively: Chris Claremont's X-Men can indeed be read as Kitty Pryde's bildungsroman.

Background: It is important that the residual bowel adapts after massive resection. The necessary intestinal adaptation is a progressive recovery from intestinal failure through increase in absorptive surface area and functional capacity and includes both morphological and functional adaptations. Objectives: The aim of this study was to investigate intestinal morphological and functional adaptations of small bowel syndrome (SBS) model rats (SBS1W) 7 days after bowel resection. Materials and Methods: Male sprague–dawley rats (n = 20/group) underwent either a 75% proximal small bowel resection (SBS1W group) or a control operation (control group). Markers of morphological adaptation were revealed by TEM analysis of H&E-stained tissue samples. The intestinal barrier condition was assessed by BT, and sIgA concentration in intestinal mucus was measured by ELISA. Contractility and the slow wave rhythm of the entire intestinal remnant were measured and recorded. Results: The SBS1W group experienced more weight loss than control group and had a clearly different intestinal morphology as revealed in TEM images. Compared with control rats, the SBS1W group had a lower sIgA concentration in intestinal mucus and higher BT to lymph nodes (70% vs 40%; level I), portal blood (40% vs 10%; level II), and peripheral blood (60% vs 30%; level III). Disorder of spontaneous rhythmic contraction, irregular amplitude, and slow frequency were detected in the SBS1W group by a muscle strips test. Similarly, the slow wave of the entire intestinal remnant in the SBS1W group was irregular and uncoordinated. Conclusions: The finding of intestinal adaptation following massive SBR in SBS1W rats provides more understanding of the mechanisms of progressive recovery from the intestinal failure that underlies SBS. The mechanical, chemical, immunological, and biological barriers were all impaired at 7 days following bowel resection, indicating that the SBS model rats were still in the intestinal adaptation phase.

Avaliámos a importância das bermas das estradas como áreas de refúgio para pequenos mamíferos, em paisagens Mediterrânicas intensivamente pastoreadas, e comparámos esta possível função das estradas como refúgio com o papel fundamental das galerias ripícolas como reservatórios de diversidade biológica. Para esse efeito, foram realizadas capturas de micromamíferos em dois segmentos de estrada e em duas ribeiras da região de Évora. Foram capturados 457 indivíduos de cinco espécies diferentes. Mus spretus foi a espécie mais capturada, seguida de Crocidura russula e Apodemus sylvaticus. M. spretus apresentou uma maior abundância nas bermas de estrada do que na vegetação ripicola, enquanto que a abundância de C. russula e A. sylvaticus era semelhante para ambos os habitats. O número de capturas das três espécies foi bastante superior dentro dos habitats lineares do que na matriz circundante. Os indivíduos de M. spretus eram maiores nas ribeiras, mas significativamente menores fora dos habitats lineares, e os indivíduos de C. russula apresentavam uma melhor condição corporal nas bermas das estradas. Tanto as estradas como as ribeiras exerceram um forte efeito de barreira aos movimentos dos micromamíferos. Concluímos então que as bermas das estradas actuam como habitat de refúgio em áreas sub-óptimas das paisagens Mediterrânicas. ABSTRACT: We assessed the importance of road verges as refuge areas for small mammals, in highly intensified grazed pastures on a Mediterranean landscape, and compared road function as refuge with the fundamental role of riparian galleries as reservoirs of biological diversity. For this purpose, a small mammal trapping study was undertaken on road verges and on small stream sides. We sampled two road segments and two streams in the vicinity of Évora, Portugal. We captured a total of 457 individuals of five different species. Mus spretus was the most common species captured, followed by Crocidura russula and Apodemus sylvaticus. M. spretus was more abundant on road verges than on riparian strips, whilst the abundance of C. russula and A. sylvaticus were similar in the two habitats. Captures of the three species were much higher inside both linear habitats than on the surrounding matrix. M. spretus were bigger on stream sites but significantly smaller outside the linear habitats and C. russula had better body conditions on roads. 8oth roads and streams exerted a strong barrier effect to small mammals' movements. We conclude that roadside verges act as refuge habitat in sub-optimal Mediterranean landscapes.
