Der volle Inhalt der QuelleKarol Szymanowski's music has fascinated me for a long time. The first time I encountered his name was in Artur Rubinstein's autobiography, which recounts how they first met and narrates many anecdotes about their friendship. At the time, I was living in Brazil, and was unable to find any recordings of his music. Nonetheless, Rubinstein's ardent praise of him (“a master!”, “a great Polish composer!”, “a powerful, original personality”) made me very curious, and I did not abandon my desire to keep looking for his music. Then, when I moved to Montreal in order to start my undergraduate degree at McGill University, I was finally able to find many recordings of his works at the school's library.[...]

Der volle Inhalt der QuelleThis paper seeks examine some of the aesthetic elements present in the creation of O Guesa, of maranhense poet Joaquim de Sousa Andrade, better known as Sousândrade. Looking up show that the form of his poetry not just in a romantic whim of subjectivity, lacking in aesthetic programme defined. From the freedom of forms conquered in romanticism, the poet demonstrates clarity in his poetic creation, using the \"reflection\", the \"imagination\" and the \"fragmentation\" to create a form of objetivation counterpart to the wild nature of the muísca legend of Guesa. Moreover, such a poetic establishes itself as a means of expression of their internal conflicts and their vision about the social conflicts of his time.
Roque, Joaquim Iarley Brito. „Continuidade e descontinuidade: a lÃgica do fragmento na filosofia de Walter Benjamin“. Universidade Federal do CearÃ, 2013. http://www.teses.ufc.br/tde_busca/arquivo.php?codArquivo=10048.
Der volle Inhalt der QuelleO presente trabalho se propÃe a apresentar o itinerÃrio filosÃfico seguido por Walter Benjamin (1892-1940) destacando o quanto sua âgnoseologiaâ pretende superar a lÃgica dedutiva e sistemÃtica das ciÃncias e alcanÃar a lÃgica fragmentÃria da realidade atual sem encobrir todos os elementos que a constituem. O pensador lanÃa na introduÃÃo crÃtica-epistemolÃgica de sua obra Origem do Drama Barroco AlemÃo e em sua Passagens conceitos como os de alegoria, monadologia, montagem, apresentaÃÃo, dentre outros, em uma perspectiva filosÃfica que de forma inovadora e original tenta ressaltar a necessidade de levantarmos questÃes referentes ao primado do fragmentÃrio sobre o sistemÃtico no Ãmbito dos mÃtodos e das teorias filosÃficas de nosso tempo. Ressaltando as particularidades de tal proposta epistemolÃgica, e como esta se aplica no todo de sua filosofia apresentaremos o quanto sua crÃtica se direciona para o positivismo, o historicismo, e principalmente Ãs concepÃÃes filosÃficas oriundas do idealismo absoluto. Contra tal perspectiva o pensador aplica a lÃgica do fragmento, da descontinuidade, na construÃÃo de suas Teses sobre o conceito de histÃria destacando o quanto à emergente a necessidade de se fundar uma filosofia contrÃria ao procedimento lÃgico-dedutivo e matemÃtico por estes se realizarem de forma resumida e didÃtica, deixando de lado o problema da expressÃo do singular. Por fim, o presente trabalho pretende demonstrar o quanto o mÃtodo filosÃfico de Benjamin se baseia em uma apresentaÃÃo contemplativa da verdade posta a partir de uma configuraÃÃo descontÃnua e intencional na qual os fenÃmenos sÃo salvos sem perderem sua particularidade.
This paper aims to present the philosophical itinerary followed by Walter Benjamin (1892-1940) highlighting how their "gnoseology" aims to overcome the systematic deductive logic and science and achieve fragmentary logic of current reality without cover all elements that form. The Thinker launches in the introduction-epistemological critique of his work Origin of German Baroque Drama and its Cheap concepts like allegory, monadology, assembly, presentation, among others, in a philosophical perspective that in an innovative and original attempts to highlight the need for we raise questions regarding the primacy of fragmentary on systematic within the methods and philosophical theories of our time. Emphasizing the particularities of such epistemological proposal, and how it applies in all of his philosophy present how his criticism is directed to the positivism, historicism, and especially the philosophical conceptions derived from the absolute idealism. Against such a perspective thinker applies the logic of the fragment, the discontinuity in the construction of his Theses on the Philosophy of History is emerging as highlighting the need to establish a philosophy contrary to procedure and logical-deductive mathematical for these are held in a summarized and didactic, leaving aside the problem of singular expression. Finally, the present work aims to demonstrate how the philosophical method Benjamin is based on a presentation called contemplative truth from a discontinuous and intentional setting in which phenomena are saved without losing their distinctiveness.

Der volle Inhalt der QuelleThis thesis presents a translation of Aristophanes fragments and three studies about them. The initial chapter, of a more general nature, deals with the sources where the fragments are to be found, the context in wich they were created and their transmission, mainly through scholiasts and lexicographers. The other two chapters focus on two specific comedies: Geritades (Geritads) and Banqueters (Daitals), and parallels are drawn with extant comedies. Geritades is the object of comparative analysis with Frogs, since both plays are concerned with literary criticism. As to Banqueters, the thesis looks into points of contact with Clouds: the contrast between the old education and the new education is a central theme in both comedies. The second part of the thesis consists of an academic translation of the five hundred eightynine fragments, from the Greek original into Portuguese. This corpus corresponds to the totality of the comedians fragments, with the exception of those fragments that are not attributed to any specific comedy, the so called incertae fabulae.
Henriques, Olga Kotchetkoff. „"Caracterização da vegetação natural em Ribeirão Preto, SP: bases para conservação"“. Universidade de São Paulo, 2003. http://www.teses.usp.br/teses/disponiveis/59/59139/tde-29042004-130918/.
Der volle Inhalt der QuelleIn a search to establish a solid base for conservation of forest fragments in Ribeirão Preto, SP, a diagnosis of the natural vegetation of the municipality was done. There are 102 forest remnants and in 99 of them an expeditious floristic survey was carried out. In this survey, 494 tree species were found belonging to 74 botanic families along with 31 exotic species. Based on the species composition of each fragment, a Detrended Correspondence Analysis (DCA) was conducted using the soil class where the fragment is found as categorical variable. This analysis indicates the existence of four vegetation groups: mesophytic forests, deciduous forests, swampy forests and cerrado, that occur respectively in purple latosol, lithosol, hydromorphic soil and dark red latossol or yellow red latossol. Each group presents its own floristic composition and typical vegetation physiognomy. The richness of species found in each fragment was from 13 to 134 species. There is a very large number of species that are very difficult to find - 275 species (52,38%) that occur in less than 5% of the fragments and 9 species (1,71%) occur in more than 50% of the remnants. There are species with rare occurrences in all fragments, but they tend to occur in larger number in the bigger ones. Each fragment presents a small percentage of the total of species, which indicates that to preserve the species diversity all the fragments are important. Generally, the initial secondary and animal dispersed species predominate in the fragments with the tendency to increase the proportion of the pioneer and wind dispersed species with the increase of the human disturbance. The majority of the fragments are small and isolated. The Principal Component Analysis (PCA) shows that the area and the core area, shape factor and fractal dimension, and the proximity index and similarity are, respectively, the main factors acting on the first three axes. The area and the core area showed significant and positively correlated with the species richness in the mesophytic and deciduous forests. The shape and the isolation did not show correlation with the species richness. Considering the biological factors (richness and proportion of species with rare occurrence) and spatial patterns (fragment area, core area proportion and similarity index), the conservation value (VC) was built, which allows us to set a hierarchy of the fragments according to their importance to conservation. The joint analysis of the result of this index and the fragments spatial distribution indicates that there are two situations that deserve attention: 1) many fragments with high conservation value are located in the urban expansion area and therefore exposed to a bigger human disturbance; 2) There is a concentration of large fragments, which are close to each other, that show a high VC in the southern region of the municipality, along the Onça creek, that includes mesophytic forests,swampy forests and cerrado. In both cases the creation of Environmental Protection Areas (APA) are suggested in order to enhance the conservation actions in these areas.

Der volle Inhalt der QuelleThis study describes and characterizes three of poetic genres which, according to tradition, had been practiced by Pindar: hyporchemata, parthenia and prosodia. The description was mainly carried out from the study of the testimonies of ancient authors, from the analysis of the remaining fragments of these genres and from the discussion of knowledge accumulated by modern criticism on the issue. We sought to define what each of these genres, its origin, its basic characteristics, differences and similarities with respect to the other melic genres, purpose, occasion for which were made, the situation in which they were executed and the main authors who practiced them. In addition, we performed a detailed comment of pindaric fragments classified in these genres, highlighting issues related to the poetic, historical, mythical, lexical, textual and metrics dimensions, seeking to interpret each fragment. Additionally, it was discussed the classification, by ancient sources and the modern editors, of these fragments in the genres studied. Finally, we performed a translation of these odes to the Portuguese.

Der volle Inhalt der QuelleOsteochondrosis is a major developmental orthopedic disease affecting horses and is usually defined as a failure in the endochondral ossification process. Unfortunately its mechanisms are not defined but it is believed to be a multifactorial etiology related to a genetic predisposition, nutritional imbalance or excess, endocrine factors and biomechanical forces acting on the joints. Osteochondritis dissecans, one of the presentations of osteochondrosis, occours when after stopping the process of ossification, there is a breakdown of the chondrocytes columns and necrosis of the basal layer, creating an area of weakness, where biomechanical forces when applied can result in the separation of cartilage or osteochondral fragments. Its incidence is related to foals with rapid growth, in predisposed joints as tarsocrural, metacarpal/ metatarsalphalangeal and femorotibiopatellar. Usually the lesion develops in the first year of life, but clinical signs may appear later or even go unnoticed. Within the clinical signs, joint effusion is the most common, which may come or not associated with lameness. The diagnosis is confirmed by radiographic examination including changes in prone locations to OCD formation, as intermediate ridge of the tibia, lateral ridge trochlear of the talus, dorsal proximal edge of the first phalanx, plantar medial edge of the first phalanx and the lateral trochlear ridge of the femur. Because these lesions may involve more than one limb, the contralateral joint should be radiographed or even four limbs in the metacarpal/ metatarsalphalangeal. Although there are various forms of treatment most authors recommend surgical excision arthroscopically as this has a higher success rate with best functional and cosmetic results. There are conflicting studies concerning prognosis and best time to refer the animal for surgery. To answer these questions and present the results obtained with surgical treatment in the medium and long term this work was done. In this study we analyzed 75 cases of horses suffering from OCD, with a total of 106 joints treated surgically, which where the treated took place over a minimum of 12 months and a maximum of five years. OCD affected mainly animals up to 4 years (65%) in the period prior to tame or time-taming (63%), and the majority had no clinical signs (36%) or had lameness associated with joint effusion (33%). Most lesions were located in the tarsocrural joint (57%), in the intermediate ridge of the tibia (71%). After surgery 72% of horses showed no clinical signs, and the improvement was more significant in animals 3 and 4 years (100%) and little improvement of lameness in the animals over six years (27%).

Der volle Inhalt der QuelleThis dissertation aims at portraying the poetry of Joaquim Sousândrade (1832-1902) as a creation in the field of literary practices in the 19th century Romantic aesthetic. His stylization processes and critical revision on models of literary tradition from the epic genre will be particularly studied. Along the work, the narrative poem The Guesa (1888) will be analyzed which is considered representative of a distinct perspective from Brazilian Romantic Nationalism referring to the poets work related to forms and poetic genres. It can observed a dissolution of the notion from the epic genre, as such the classification in poetic precepts previous to Romanticism, enabling the creation of an original work. The narration of The Guesa assimilates characteristics of the epic genre; however, it cannot be classified as such, as it features elements that are not provided in the perceptive of that genre. Importantly, The Guesa does not suggest an effort to rehabilitate the epic genre; but as it will be studied further the poet engenders a new formal organicity that assimilates the beauty of prescript poetic forms in old doctrines and articulates them with Romantic aesthetic procedures, especially those that need a start in the use of aesthetic categories that give meaning and sense to the Romantic terms genius, sublime, fragment, among others, at the time of Sousândrade. Such terms may favor artistic creation based on significant theoretical criteria, different from normative precepts of poetic arts that used to regulate imitation in works of the Ancients. It is important to emphasize that, in the work of Sousândrade, the use of those aesthetic categories during the conception of his work has an essential role, allowing the poet to make experiences with literary genres that make it distinct from the poetic creation of other Brazilian Romantic poets.

Der volle Inhalt der QuelleThis study deals with an attempt to look at the city, specifically São Paulo, and perceive color as a participant of the many elements that constitute and characterize it -- as the identity of a place and part of the memory of those who experience the city. This has been done in high-traffic areas of passersby, where the city is even more fragmented and receives the most experienced interference in their daily life, by proposing two ways to capture and record the color: by the route, recorded in a photo essay, and by the fragments, recorded in a pictorial way -- linking people\'s memory to the colors of the places. In both cases, it appears that color expressiveness always depends on its functions and context; it is a matter of relationship between colors.

To get to our objetives, we firt ran each of these programs on twelve intances. After this,we compared the outputs with the sequences from wich the fragments were originally obtained. In this comparison,we took into consideration three problems related to fragments assembly (sequencing errors, chimeric fragments and repeats regions). We conclude that no one of the packages we tested is more efficient than the others when considering all the problems cited above. If we consider a particular problem, the we observed different performances among the programs. Even more, we compare the packages with respect to theirs to CPU times.

Os Euglossini distribuem-se exclusivamente na região neotropical. Os machos são facilmente atraídos por terpenóides e hidrocarbonetos aromáticos sintéticos, análogos àqueles presentes nas fragrâncias florais. Essa técnica tem auxiliado no conhecimento da fauna de diferentes áreas biogeográficas, revelando novas espécies. Nos últimos anos, a preocupação crescente com a perda de biodiversidade em seu sentido mais amplo vem se manifestando entre os pesquisadores que estudam aspectos da biologia e ecologia de abelhas, em grande parte, pelo reconhecimento da forte dependência de espécies de plantas cultivadas e nativas em relação às abelhas para a polinização. A habilidade dos Euglossini de se dispersarem e encontrarem flores isoladas e iscas aromáticas distantes tem levado à sugestão de que as abelhas atraídas para as fragrâncias vem de uma vasta área que pode incluir diferentes habitats. Este trabalho teve por objetivos: (1) Conhecer a composição e a diversidade de espécies, a fenologia e o uso de habitats da comunidade de Euglossini de uma área composta por fragmentos de Mata Atlântica, de diferentes tamanhos, em Jacutinga, Sul de Minas Gerais. (2) Avaliar o padrão de deslocamento das diferentes espécies entre esses fragmentos. Abelhas Euglossini foram coletadas em quatro fragmentos de diferentes tamanhos e diferentes graus de degradação na Serra da Forquilha, município de Jacutinga, MG com auxilio de iscas aromáticas. As coletas foram realizadas mensalmente, no período de abril de 2007 a março de 2008. Para analisar a similaridade entre as estações, foi utilizado o Coeficiente de Correlação de Pearson e a Análise Multivariada Conglomerada. A diversidade de espécies foi avaliada por meio dos índices de Shannon – Winner e Índice de Simpson.. Foram coletados 1778 machos de Euglossini, pertencentes a quatro gêneros e dez espécies.

The orchid bees are distributed exclusively in the Neotropics. The males are easily attracted by terpenoids and aromatic hydrocarbons, synthetic analogs to those found in floral fragrances. This technique has helped in the knowledge of fauna from different biogeographic areas, revealing new species. In recent years, the growing concern over the loss of biodiversity in its broadest sense has manifested itself among researchers who study aspects of biology and ecology of bees in large part by the recognition of the strong dependence of species of cultivated and native plants in relation to bees for pollination. The ability of orchid bees to disperse and find isolated flowers and scented baits far has led to the suggestion that bees attracted to the fragrance comes in a vast area that may include different habitats. This study aimed to: (1) Know the composition and species diversity, phenology and habitat use of community Euglossini an area composed of Atlantic forest fragments of different sizes, Jacutinga, South of Minas Gerais. (2) To assess the pattern of displacement of various species between these fragments. Euglossini were collected in four fragments of different sizes and different degrees of degradation in Mountain Fork, City of Jacutinga, MG aromatic with the aid of bait. Samples were collected monthly between April 2007 and March 2008. To analyze the similarity between the stations, we used the correlation coefficient of Pearson and Multivariate Analysis Conglomerate. Species diversity was assessed by the Shannon - Winner and Simpson index. We collected 1778 male orchid bees, belonging to four genera and ten species. The most abundant species were Eulaema nigrita, Euglossa annectans, Eufriesea violacea and Euglossa truncata. Eucalyptol was more efficient scented bait attracting 49.6% of males of all ten species.

Der volle Inhalt der QuelleIn view of the haphazard development of the agriculture in the Corumbataí River Basin, this area presents high deforestation rate and forest fragmentation, which makes indispensable the development of conservation projects and handling of the forest fragments, at the level of the fragment itself as well as on the scale of the landscape in which it is inserted. The present work is part of a project of Recovery and Conservation of the Forest Cover of Corumbataí River Basin and has as its objective the determination of the patterns of space distribution of the forest fragments in this basin and its relationship to slope and nutritional limitation of the soils. A Geographical Information System was used to digitalize, manipulate and overlay the data. The use categories and occupation of the soil were obtained from LandSat TM-5 satellite image. The great majority of the forest fragments found in this basin presented area of less than 10 ha. The largest percentages of forest fragments cover were found in the areas of large slopes. The relationship between nutritional limitation of the soils, average size of the fragments and percent cover was not found to be well defined for this basin.

Bovine herpesvirus type 1 ( BHV - 1 ) is recognized as an important pathogen of economic losses in cattle , these animals causing diseases known as infectious bovine rhinotracheitis ( IBR ) , infectious pustular vulvovaginitis , infectious balanoposthitis and neurological disorders . For effective control of these diseases, the correct diagnosis is necessary, but none of the available tests enables a quick result made the field. Considering this, the aim of this study was to construct a combinatorial antibody library, for it to be used in the future development of new diagnostic approaches . Two breed White Leghorn chickens were immunized with 105.5 TCID50/ml of BoHV - 1, birds were necropsied , their spleens removed for total RNA extraction , cDNA synthesis , amplification of gene fragments encoding the light chain ( VL ) and heavy ( VH ) and production of scFv ( v) fragments. These fragments were cloned into vectors fagomidiais expressed as fusion proteins on filamentous phage and amplified by infection of E. coli. Selection of viral particles ( fused scFv) binding to the BHV -1 ( biopanning ) by six cycles were performed. The affinity of the scFv antibody library BHV -1 observed in ELISA shows that the produced fragments are reactive to HIV, the use of such antibodies in the development of new diagnostic platforms is possible . The sequencing results showed a reduction of variability in comparison to the dot blot previously performed, and a desirable feature of this process , however, it was possible to sequence the clones efficiently, it has been found , therefore, a need to further analyze the shape of results
O herpesvírus bovino tipo 1 (BoHV-1) é reconhecido como um importante patógeno de perdas econômicas em bovinos, causando nestes animais enfermidades conhecidas como Rinotraqueite Infecciosa Bovina (IBR), vulvovaginite pustular infecciosa, balanopostite infecciosa e desordens neurológicas. Para um efetivo controle destas enfermidades, o diagnóstico correto se faz necessário, porém nenhuma dos testes disponíveis possibilita um resultado rápido feito a campo. Considerando isto, o objetivo deste estudo foi construir uma biblioteca combinatorial de anticorpos, para que esta seja futuramente utilizada no desenvolvimento de novas abordagens diagnósticas. Duas galinhas da raça White Leghorn foram imunizadas com 105,5 DICC50/mL de BoHV-1, as aves foram necropsiadas, seus baços retirados para extração de RNA total, síntese de cDNA, amplificação dos fragmentos gênicos codificantes das cadeias leve (VL) e pesada (VH) e produção de fragmentos scF(v). Estes fragmentos foram clonados em vetores fagomidiais, expressos como proteínas de fusão em bacteriófagos filamentosos e amplificados pela infecção de bactérias E.coli. Foi realizada a seleção de partículas virais (scFv fusionados) ligantes ao BoHV-1 (biopanning) através de seis ciclos. A afinidade da biblioteca de anticorpos scFv ao BoHV-1 observada no teste de ELISA mostra que os fragmentos produzidos são reativos ao vírus, sendo possível a utilização destes anticorpos no desenvolvimento de novas plataformas de diagnóstico. Os resultados de sequenciamento mostraram uma diminuição da variabilidade em comparação ao dot blot realizado anteriormente, sendo uma característica desejável neste processo, porém não foi possível sequenciar os clones de modo eficiente, verificando-se, portanto, a necessidade de analisar de forma mais aprofundada os resultados obtidos .

Der volle Inhalt der QuelleThis research studies the romance on the end of the twentieth century in Colombia between 1990 and 2005 in a panoramic orientation. The analysis is approached from the point of view of writing and is made through the analysis of some novels of the period from the concepts of world, author and fragment. This research, also, is focused on the novels Rosario Tijeras by Jorge Franco, Entre fantamas by Fernando Vallejo and Pavana del angel by Roberto Burgos Cantor. On this way, the study presents three chapters; the introduction presents the purpose of the research and its explanation. The first chapter works with the concept of worldliness in the romance Rosario Tijeras by Jorge Franco, in a direct dialogue with the novel Después de todo by Piedad Bonnett and El anarquista jubilado by Roberto Rubiano. The second chapter attempts to define the concept of author and how it is configured in Entre fantasmas by Fernando Vallejo, for that purpose, it is brought into dialogue with Memorias de un hidalgo disoluto by Héctor Abad Faciolince, Amirbar by Alvaro Mutis, Érase una vez el amor pero tuve que matarlo by Efraim Medina Reyes and Vida feliz de un joven llamado Esteban by Santiago Gamboa. The third chapter discusses how the fragment is presented in Pavana del ángel by Roberto Burgos Cantor, a novel that is part of the literary tradition of Colombia and in particular, the Colombian Caribbean. This novel is set in relation to the novel Opio en las nubes by Rafael Chaparro Madiedo and also relates to the romance Los cuadernos de N., by Nicolás Suescún. The conclusion tries to define the way this research was developed.

Introdução: O PSA ( antígeno prostático específico ) é a principal ferramenta no rastreamento do Câncer de Próstata. Estudos buscam melhoria no diagnóstico criando combinações do PSA com suas variáveis: PSAlivre/PSAtotal; Densidade do PSA; Velocidade do PSA; associação com a idade do paciente; etnia e hereditariedade para Câncer de Próstata. O diagnóstico do Câncer de Próstata é realizado através da análise do tecido prostático, obtido através da biópsia prostática, guiada por ultrassonografia, sendo considerado o procedimento padrão. O objetivo deste trabalho é avaliar a frequência de Câncer de Próstata em homens: submetidos 18 fragmentos de biópsia prostática e comparar com a positividade se analisados apenas os 12 fragmentos iniciais. Material e método: Entre maio de 2008 a outubro de 2013, foram analisados 216 prontuários de pacientes, submetidos à biópsia prostática com 18 fragmentos, que apresentavam PSAtotal ≥ 2,5ng/ml, PSAlivre/PSAtotal ≤ 19%, densidade PSA ≥ 0,15 ng/ml/cc, com toque retal normal, e ausência de nódulos prostáticos à ultrassonografia transretal. As biópsias prostáticas por agulha foram guiadas por Ultrassonografia transretal e distribuídas da seguinte maneira: 3 fragmentos base direita; 3 fragmentos base esquerda; 3 fragmentos 1/3 médio direito; 3 fragmentos 1/3 médio esquerdo; 3 fragmentos ápice direito e 3 fragmentos ápice esquerdo. Estes foram numerados de 1 a 18 e separados em 2 grupos: grupo 1 com os fragmentos 1 a 12, sendo 2 fragmentos de cada região prostática e o grupo 2 com os fragmentos 13 a 18, sendo 1 fragmento de cada região prostática, cada fragmento foi analisado separadamente. Foi realizada comparação da positividade entre os 18 fragmentos e apenas os 12 iniciais. Os pacientes com diagnóstico de câncer nos 12 fragmentos iniciais foram comparados com aqueles apenas na avaliação de todos os 18 fragmentos com relação aos valores do PSA e volume prostático. Resultados: Foram avaliados 216 homens com idade média de 64 +- 8,0 anos, com extremos de 34 a 90 anos. A incidência de pacientes com Câncer de Próstata em 12 fragmentos foi de 42/216 (19,44%) e em 18 fragmentos a incidência foi de 58/216 (26,85%); com aumento de 38% na capacidade de detecção, o que nos revela 7,45% a mais de tumores. Ao compararmos os pacientes que apresentaram positividade da biópsia já nos 12 primeiros fragmentos (42 pacientes), com aqueles com positividade apenas na avaliação de todos os 18 fragmentos (16 pacientes), verificamos que: os pacientes com positividade apenas com 18 fragmentos apresentaram maior valor de PSA e próstata maiores. O que leva a consideração que pacientes com próstata maiores e maiores valores de PSA se beneficiariam de um maior número de fragmentos. Conclusões: A análise de 18 fragmentos de biópsia de próstata em relação a 12 fragmentos, mostrou aumento de positividade na detecção de câncer de próstata e estes pacientes tiveram benefício com o aumento do número de fragmentos e apresentaram maior PSA e maior volume de próstata.
Introduction: PSA (Prostate-Specific Antigen) is the main tool for screening for prostate cancer, and studies now seek to improve the diagnosis by creating combinations of PSA with its variables, free/total PSA, PSA density, PSA velocity, and an association with the patient's age, ethnicity and heredity for prostate cancer.The diagnosis of prostate cancer is achieved by the analysis of prostatic tissue obtained by prostate biopsy guided by ultrasound, and it is considered the standard procedure. The objective of this study was to evaluate prostate cancer frequency in men undergoing prostate biopsy of 18 fragments and to compare that with positivity, when only the first 12 fragments were analyzed. Materials and methods: from May 2008 to October 2013, 216 medical records of patients undergoing prostate biopsy that had total PSA between 2.5 and 10 ng/ml, free/total PSA ≤ 19%, PSA density ≥ 0.15 ng/ml/cc3 with normal digital rectal exam and absence of prostate nodules of trans rectal ultrasonography were analyzed. The trans rectal ultrasound guided biopsies involving using needles were distributed as follows:3 right base fragments, 3 left base fragments, 3 1/3 right mid fragments, 3 1/3 left mid fragments, 3 right apex and 3 left apex fragments. These fragments were numbered from 1 to 18 and separated into 2 groups: Group 1 - 1 to 12, with two fragments of each prostatic region - and Group 2 - 13 to 18, with one fragment from each prostatic region (each fragment being analyzed separately).Positive comparison was made between the 18 fragments and only the first 12.Patients diagnosed with cancer in the first 12 fragments were compared with those for which all 18 fragments were analyzed regarding the values of PSA and prostate volume. Results: 216 men with mean age of 64 + - 8.0 years, with extremes 34-90 years were evaluated. The prevalence of patients with prostate cancer in 12 fragments was 42/216 (19.44%), and in 18 fragments it was 58/216 (26.85%); with an increase of 38% in the detection capacity, which shows 7.45% more tumors. When comparing the patients who had positive biopsy in the first 12 fragments (42 patients) with those with positivity only in the evaluation of all 18 fragments (16 patients), it was found that patients with positivity only in the 18 fragments showed higher PSA value and larger prostates. This leads to consider that patients with larger prostates and higher PSA values would benefit from a greater number of fragments. Conclusions: the analysis of 18 prostate biopsy samples compared to 12 fragments showed a positive increase in prostate cancer detection. Also, the patients who were benefited from the increase in the number of fragments had higher PSA and larger prostate volume.

Der volle Inhalt der QuelleFrom the disenchantment of the natural world in the sixteenth century, changes in the environment and society relationship occurred, allowing pollution and depredation of the environment for the accumulation of capital. And since then, the development model, widespread in rural areas, has been promoting environmental degradation and forest fragmentation. This, in turn, is directly related to the decision making of the residents of rural areas in their practice, which is subject to prevailing cultural system. The hypothesis tested was that the greater the ratio of residents of rural properties with the market and urban life, lower conservation of forest fragments and objectives of this study were to evaluate the relationship between practices of rural residents of the municipality of Jacarei and conservation of fragments. Also, to identify which practices would be consistent with the assumptions of sustainability in its various dimensions, in reality, so that this analysis could contribute as grants for proposals for public policies that focus. We conducted a case study of the rural area where Jacarei 6 were selected farms located in 10 major roads of the city, in a sample of 60 units. The choice of properties was random, semi-structured interviews and on-site observation of forest fragments and backyards being held. It was identified that there are practices that do not promote the conservation of forest fragments, especially those properties related to the market, and also those with monoculture leisure. It was also observed that there are different cultures and practices that promote the conservation of natural attributes and forest fragments, as polycultures and agroforestry systems beyond the family farm, that are inserted into an environmental sustainability perspective. It was possible to establish that the strategies to achieve it imply the expansion and enhancement of family agriculture and agroforestry therein. These strategies constitute the starting point for planning aimed at rural public policy is also necessary to consider the aspects that favor the other dimensions of sustainability, ecological beyond.

Der volle Inhalt der QuelleThis thesis presents the translation of the remaining fragments of the epic poem Annals by Quintus Ennius (239ca. 169 BC). An introductory section discusses what is known about the poet, taking the ancient authors quotes that refer to him as a starting-point. In this initial section a study on the Annals is also included; it observes the poem according to the ancients point of view and to what it is today, in the fragmentary form in which it has come down to us, the philological work of critics from all over the world being its unifying element. The kernel of this text consists of the translation and commentary of the 420 fragments taken from the Italian edition of Valmaggi (1945). The comments are based primarily on the contributions of Skutsch (1985), Steuart (1876), Warmington (1988) and Vahlen (1967), and the contextualization given to each fragment, since such procedure aids and enables my search for the theme it is connected with and thus explains why each fragment was included in the book it is part of. I then analize the fragments one by one, mark its stylistic motivations and linguistic uses, and search for the meaning of each text-fragment, which is done through diverse resources, such as the help of different dictionaries, word comparison in distinct fragments either of the Annals or other Ennius works, and the study of a words usage in similar contexts found in other authors, and in different contexts of Ennius contemporary authors.

O presente estudo, de cunho qualitativo, tem como propósito compreender quais experiências tornaram determinados professores inesquecíveis para seus alunos. Justifica-se pelo entendimento de que educação e emoção, sendo indissociáveis, capacitam o professor para provocar os “atravessamentos”, segundo Larrossa (2002) aquilo que nos toca, que nos passa e que ao passar nos transforma, assim tornando-o inesquecível aos olhos de seus alunos. O estudo desenvolveu-se no município de Poços de Caldas, em Minas Gerais, tendo como participantes 63 alunos e 04 professores entre os indicados pelos alunos como inesquecíveis, abrangendo alunos que estudaram e professores que atuaram no período compreendido entre 1980 e 2010. Para alcançar o objetivo foram utilizadas como estratégias de pesquisa e instrumentos de coleta de dados: a pesquisa bibliográfica, questionários aplicados aos alunos e entrevistas semiestruturadas com os professores indicados. Com base na discussão a respeito da experiência (Larrosa Bondía, 2007), da memória (Benjamin, 1985), da emoção Vigotsky (1998), Wallon (2007) e demais autores referenciados, pode-se concluir que a emoção que permeia a relação entre alunos e professores, sendo provocada pelas experiências que vivenciam juntos, constitui sua memória e pode marcar sua subjetividade, transformando-os para sempre. E, ainda, que alguns professores se tornaram inesquecíveis para seus alunos - ao transformar suas vidas, ao marcá-las com algo significativo, muitas vezes absolutamente apartado dos conteúdos que ensinou, mas com muito valor para sua constituição como ser singular. As escolhas por esses professores basearam-se tanto em características pessoais quanto profissionais, mas, principalmente, na qualidade das experiências vivenciadas em conjunto e na emoção que fluiu da convivência com eles.
The purpose of this qualitative study is to understand which experiences have made certain teachers unforgettable for their students. It is justified by the understanding that education and emotion, being indissociable, enable the teacher to provoke the "crossings", according to Larrossa (2002) what touches us, that passes us and that when passing makes us, thus making it unforgettable to the eyes of his students. The study was developed in the municipality of Poços de Caldas, in Minas Gerais, with 63 students and 04 teachers among those indicated by the students as unforgettable, covering students who studied and teachers who worked during the period between 1980 and 2010. To achieve the objective was used as research strategies and data collection instruments: bibliographic research, questionnaires applied to students and semi-structured interviews with the indicated teachers. Based on the discussion about the experience (Larrosa Bondía, 2007), memory (Benjamin, 1985), the emotion Vygotsky (1998), Wallon (2007) and other authors referenced, it can be concluded that the emotion that permeates the relationship between students and teachers, being provoked by the experiences they experience together, constitutes their memory and can mark their subjectivity, transforming them forever. And yet, some teachers have become unforgettable to their students - by transforming their lives by marking them with something meaningful, often quite apart from the content they taught, but with great value to their constitution as a unique being. Choices for these teachers were based on both personal and professional characteristics, but mainly on the quality of the experiences lived together and the emotion that flowed from living with them.

Der volle Inhalt der QuelleThis dissertation proposes a reading of Lecciones para una liebre muerta (2005a) and El gran vidrio (2007) written by Mario Bellatin. These works were analyzed concerning the aesthetic reworking they put forward of two narrative features: the novel and the autobiography. In this sense, the theoretical notions of the French post-structuralism, developed by the so called philosophers of language (Barthes, Blanchot, Derrida e Foucault), such as the writing, the fragment, the genre appearing as a guidance for the artistic creation instead of a norm and the transgression were central to approach the new proposals embraced by the aforementioned works of Bellatin. Both the novel and the autobiography have had the purpose, historically, to trace life. The former by ambitioning a totalizing form that would recompose the meaning lost in the empirical existence, and the latter by aiming the understanding of the self. Therefore, it has been explored this place which the bellatinian world has granted to the living by working it within these genres. Our hypothesis is that by waging on the exacerbation of some formal features, such as: the self-figuration, the opening to other artistic languages, the narrative fragmented and the resumption of the work itself, the bellatinian literature uncover an unique universe that tensions the ideals of the literary modernity, without rupturing ultimately with them. Lecciones para una liebre muerta has enabled us to position a question about the existence of a new configuration of the novel inside the context of the contemporaneity or about the explicitation of its symbolic ineffectiveness on the present. On the other hand, El gran vidrio allowed us to enquire the discourse status of the self in a cultural scenery that has reconfigured the notion of the subject

Der volle Inhalt der QuelleThis dissertation aims at examining the unfinished traits in the poetry of Álvares de Azevedo, and approaching them using the theoretical fundaments of the genre fragment. The object of this study, O poema do frade, is a narrative composing which is constantly relegated to a secondary position in the poets critical fortune. This negative appreciation derives exactly from his digressive and irregular style, often seen as defective. O poema do frade is strongly characterized by the mediation of an ironic narrator, inclined to a rambling discourse, often nonlinear, and full of meta-poetic discussion. In the poem, the multiplicity of matters, apparently discontinuous, is unified in the thematization of a great aesthetic debate about the impossibility of an epic in the modernity. From this perspective, O poema do frade dialogues with the controversial project of composing an epic narrative in nineteenth-century Brazil, sponsored by the local imperial politics, and specially fed by the poets connected to the indianist movement. By questioning the epic feasibility in his time, Álvares de Azevedo performs a review of the neoclassical poetic tradition, as well as his own, applying the romantic principle of closing in the criticism and the poetry fields, or in other words, absorbing the critical reflection inside the work of art.

Plants may present a broad variation in phenological features, as a consequence of the interaction between biotic and abiotic factors that influence reproductive success. Thus, areas that are subjected to different degrees of anthropogenic pressure offer distinct conditions to the establishment and development of plant populations, including the occurrence and the intensity of phenological events. One of the most important factors that influence plant development in dry forests is the precipitation, mainly for annual herbaceous species, which generally grow and reproduce in the rainy season. The phenology of these plants is poorly documented, mainly in the caatinga, a dry forest vegetation that grows in NE Brazil. For this reason, this study aims to learn more about the phenology of caatinga grass, with the following hypotheses: 1. The period of manifestation of phenophases may differ between a disturbed and a preserved area in a region of caatinga. 2. The level of synchrony of the populations of phenophases occur simultaneously in both areas tend to be different. 3. The amount of flowers and fruits of herbaceous populations studied may be different among sites (preserved and anthropic). 4. The manifestation of phenophases of herbaceous annual can have a correlation with local rainfall during its life cycle. The study was conducted in two areas of caatinga vegetation. One of them is a remnant of caatinga forest, hereafter called preserved one, and the other is an area that is regenerating, when occurred the abandone of agricultural practices. Bothe areas are located in the Instituto Agronômico de Pernambuco, Caruaru municipality, NE Brazil. In each area the vegetative and reproductive phenophases of 30 individuals of five annual, herbaceous species: Bidens bipinnata L., Commelina obliqua Vahl, Delilia biflora (L.) Kuntze, Desmodium glabrum (Mill.) DC. and Pseudabutilon spicatum (Kunth) R.E. Fr., were accompanied weekly during all their life cycle, understood from January to October 2011. The period, synchrony, number of reproductive structures and levels of correlation between precipitation and phenophases were compared between the two areas. It was observed a high synchrony in the phenological events between the two areas. It was found that the populations did not show strong variations in time and timing of their phenophases between the two environments. However, only one species did not show a high synchronization in flowering, fruiting and leaf drop for both areas. It was also noted that four species showed significant differences in number of reproductive structures produced by each population, demonstrating the interference of phenological areas in this regard. On the other hand, while it is true that many plants of the caatinga have a dependence on rainfall for its development was not seen any significant correlation between this factor and reproductive phenophases of herbs in two areas during their life cycle. For vegetative phenophases were observed a significant correlation with the local precipitation. Finally, the results of this study indicate that there is not a noticeable difference in the manifestation of phenophases in populations of the savanna grasses therophytes present in the immediate environment, but subject to different conditions as to shift the time of the phenophase, or in sync. However, the productivity, abandoned cultivation area had a greater production of reproductive structures of populations of Bidens bipinnata and Commelina obliqua, while the preserved area was more favorable for a higher production of reproductive structures of populations and Pseudabutilon spicatum and Desmodium glabrum. Thus, some herbaceous species have a more positive relationship with regenerating areas, favoring their phenological responses, while others do not have this type of relationship with these areas.
Sabe-se que as plantas podem apresentar uma variação em suas características fenológicas, resultantes de uma interação com diversos fatores entre áreas diferentes, e que essas variações podem ser fundamentais para seu sucesso reprodutivo. Nesta perspectiva, áreas que são modificadas por ações humanas oferecem condições diferentes das áreas preservadas, e isto pode afetar a intensidade e o ritmo de cada fenofase vegetal. Sabe-se também que em ambientes de florestas secas, um dos principais fatores que influencia o desenvolvimento das plantas é a precipitação, principalmente das espécies herbáceas anuais, que geralmente crescem e reproduzem-se no período chuvoso. No entanto, a fenologia de espécies herbáceas em florestas secas perturbadas ainda é pouco conhecida, principalmente na caatinga, Nordeste do Brasil. Por este motivo, este estudo tem como objetivo conhecer um pouco mais sobre a fenologia do componente herbáceo da caatinga, apresentando as seguintes hipóteses: 1. A época de manifestação das fenofases pode diferir entre uma área preservada e uma antropizada em uma região de caatinga. 2. O nível de sincronia das fenofases das populações de ocorrência simultânea nas duas áreas tende a ser diferente. 3. A quantidade de flores e frutos das populações herbáceas analisadas pode ser diferente entre os locais (preservado e antropizado). 4. A manifestação das fenofases de herbáceas anuais pode apresentar uma correlação com a precipitação local durante seu ciclo de vida. O estudo foi desenvolvido em duas áreas de caatinga, sendo uma remanescente desse ecossistema, chamada de preservada, e outra de cultivo abandonado e em regeneração natural, denominada de antropizada, ambas pertencentes ao Instituto Agronômico de Pernambuco, Caruaru-PE, Brasil. Nas duas áreas foram selecionados 30 indivíduos de cinco espécies herbáceas anuais: Bidens bipinnata L., Commelina obliqua Vahl, Delilia biflora (L.) Kuntze, Desmodium glabrum (Mill.) DC. e Pseudabutilon spicatum (Kunth) R.E. Fr., que tiveram suas fenofases vegetativas e reprodutivas acompanhadas semanalmente durante todo o seu ciclo de vida, compreendido de janeiro até outubro de 2011. Realizou-se uma comparação da época, sincronismo, número de estruturas reprodutivas e níveis de correlação entre a precipitação e as fenofases das populações dos dois trechos, esperando-se encontrar diferenças quanto a essas variáveis. Foi visto que as populações não apresentaram fortes variações na época e no sincronismo de suas fenofases, entre os dois ambientes. Entretanto, apenas uma espécie não apresentou um alto sincronismo na floração, frutificação e queda foliar para as duas áreas. Observou-se também que quatro espécies apresentaram diferença significativa no número de estruturas reprodutivas produzidas por cada população, demonstrando a interferência das áreas neste aspecto fenológico. Por outro lado, embora seja certo que muitas plantas da caatinga apresentem uma dependência da precipitação para o seu desenvolvimento, não foi visto nenhuma correlação significativa entre este fator e as fenofases reprodutivas das ervas nas duas áreas durante o seu ciclo de vida. Para as fenofases vegetativas foi observada uma correlação significativa com a precipitação local. Por fim, os resultados deste estudo indicam que não há uma diferença perceptível na manifestação das fenofases em populações de ervas terófitas da caatinga presentes em ambientes próximos, mas sujeitos a diferentes condições quanto ao deslocamento da época da fenofase, ou na sincronia. Contudo, quanto à produtividade, a área de cultivo abandonado apresentou uma maior produção de estruturas reprodutivas das populações de Bidens bipinnata e Commelina obliqua, enquanto que a área preservada foi mais favorável para uma maior produção de estruturas reprodutivas das populações de Desmodium glabrum e Pseudabutilon spicatum. Dessa forma, algumas espécies herbáceas apresentam uma relação mais positiva com áreas em regeneração, favorecendo suas respostas fenológicas, enquanto outras não apresentam este tipo de relação com essas áreas.

Der volle Inhalt der QuelleThis work is dedicated to the study of heavy nuclei fission induced by intermediate- and high-energy photons and protons, by using to this end the Monte Carlo code CRISP, therefore being an entirely computacional work. A new set of parameters for the 2001 semi-empirical mass formula proposed by Pearson is studied. Then we simulate fission reactions induced by photons and protons on 208Pb, 232Th, 237Np and 238U, and fission induced by protons on 197Au, 208Pb, 237Np e 241Am. The Bohr-Wheeler model for describing the fission process and the Weisskopf model for the emission probability of particles were used to perform the calculation. Regarding the level density parameters, a set of parameters is presented for the empirical formulas of Dostrovsky and for the fission ratio. This work also presents calculated fotofission cross section for induced reactions on 208Pb, 232Th, 237Np and 238U nuclei, spallation products of proton induced reactions on 208Pb and 197Au, and fragment mass distributions of Bremsstrahlung reactions with 238U and of proton induced reactions on 197Au, 208Pb, 237Np and 241Am. Comparisons to experimental data are shown for all calculations. A model to aproximate the fission barrier values obtaind by the ETFSI - Extended Thomas-Fermi plus Strutinsky Integral method is also presented.

Resumo: As lesões liquenóides orais (LLO), como líquen plano oral (LPO) e reação liquenóide oral por amálgama dental (RLO-AD), são doenças imunologicamente mediadas (DIM) com características histopatológicas semelhantes, porém com prognósticos distintos. As suas etiopatogenias têm sido relacionadas a polimorfismos gênicos e secreção citocinas de inflamatórias (CI), as quais são responsáveis pelas respostas imunológicas inadequadas, que causam danos estruturais à mucosa oral (MO) e estimulam o recrutamento de células inflamatórias. Assim, foi realizado um estudo em voluntários portadores de LLO (grupo-1, n=39), em voluntários saudáveis (grupo-2, n=39), e em cem amostras de DNA provenientes de voluntários saudáveis (grupo-3, n=100). A pesquisa teve como objetivos selecionar e diferenciar casos de LLO clássicas (LLO-c) por meio dos critérios de diagnósticos de LLO da Organização Mundial de Saúde (Cdx-LLO-OMS); determinar a hipossalivação nesses pacientes; analisar outros achados histopatológicos presentes nas LLO; quantificar linfócitos T (LT-CD3, LT-CD8), linfócitos B (LB), plasmócitos, mastócitos, imunomarcados contidos no infiltrado inflamatório subepitelial (IISE) nos casos de LLO a fim de avaliar as respostas Th1/2; e estimar a frequência dos polimorfismos dos genes Th1/2 envolvidos na síntese de CI através da reação em cadeia da polimerase (PCR) e polimorfismo no comprimento do fragmento de restrição (RFLP). De forma geral, pacientes do gênero feminino com idade média de 53,13 anos apresentaram maior frequência de LLO (p=0,06; OR:2,57). O infiltrado inflamatório perivascular profundo e a presença de folículos linfóides foram frequentes nas RLO-AD (p<0,001). A contagem de LB foi maior nas RLO-AD (p<0,05). A hipossalivação foi frequente em portadores de LLO (p<0,001;OR:19,72). Os alelos mutados IL4-590T,TNF-?-308A, e IL10592C foram freqüentes nos portadores de LLO (p<0,0001). Portadores de LPO apresentaram mais alelos mutados IL4-590T e IL10-592C (p<0,05). Concluiu-se, portanto que pacientes do gênero feminino com média de idade de 53 anos apresentam mais LLO. A hipossalivação foi associada à presença da lesão oral em portadores de LLO. As LLO estão associadas aos altos índices de células de reação inflamatória crônica e à expressão gênica das citocinas relacionadas às respostas Th1/2
Abstract: Oral lichenoid lesions (OLL), such as oral lichen planus (OLP) and amalgam-associate oral lichenoid reaction (AAOLR) are immunologically mediated diseases (IMD) with similar histopathologic features but distinct prognoses. Their etiopathogenesis have been related to gene polymorphisms and inflammatory cytokine (IC) secretion, which are responsible for the inappropriate immune responses that cause structural damage to the oral mucosa (OM) and stimulate the recruitment of inflammatory cells. Therefore, this study was conducted in a group of volunteers with OLL (group-1, n=39), another group comprised of healthy volunteers (group-2, n=39), and a third group comprised of hundred DNA samples obtained from healthy volunteers (group-3, n = 100). The research aimed to select and differentiate classic cases of OLL by means of diagnostic criteria for OLL of the World Health Organization (WHO-OLL-CDx), to determine the hyposalivation in these patients, to analyze other histological findings features present in OLL; to evaluate the Th1/2 by means of quantification of inflammatory cells, T-lymphocytes (CD3-TL, CD8-TL), B lymphocytes (BL), plasma cells and mast cells immunostained contained in the subepithelial inflammatory infiltrate (SEII) on the slides of OLL, and estimate the frequency of polymorphisms of genes Th1/2 involved in the synthesis of IC by means of polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Overall, female patients with mean age of 53.13 years had a higher frequency of OLL (p = 0.06, OR: 2.57). The deep perivascular inflammatory infiltrate and lymphoid follicles were common in the AAOLR (p <0.001). The LB count was higher in AAOLR (p <0.05). The hyposalivation was common in patients with OLL (p <0.001, OR: 19.72). Mutated alleles of IL4-590T, TNF-?-308A and IL10-592C were frequent in patients with OLL (p <0.0001). Patients with OLP had more mutated alleles IL4 and IL10-590T-592C, when compared to AAOLR (p <0.05). Therefore it was concluded that female patients with a mean age of 53 have more OLL. Hyposalivation was associated with the presence of oral lesions in patients with OLL. The oral lichenoid lesions are associated with high rates of chronic inflammatory cell reaction and gene expression of cytokines related to Th1/2 response

Der volle Inhalt der QuelleBased on the reading of Mínimos, múltiplos e comuns, by João Gilberto Noll, this work seeks to undertake a study on the relationship between the artist writing and the time in the figure of "fictional instants, noting the issue of the micro-relate and the fragmentary requirement (cf.P. Lacoue-Labarthe and Jean-Luc Nancy), in the view of the unfinished / unit, which casts a whole constellate hypothesis on the writing of João Gilberto Noll. Initially, a reflection on some important topics that are recurrent in the critical fortune of the writer is carried out with the intention of finding out how they reverberate in his writings; then, the fragment and its aesthetics perspectives of incompleteness and wholeness are treated with respect to time; finally, it is observed how, from these issues, the critical metaphor of the fictional instant takes place. The critical readings used as operators have been guided by the notions of the fragment (romantic), and Event which is related to the conceptual pair Cronos / Aeon Deleuzian

Der volle Inhalt der QuelleA pesquisa intitulada Aproximação de fragmentos capturados: uma poética em desenho e colagem centra-se em uma investigação poética fundada no desenho e que se inicia pela captura de elementos que são colecionados para posteriormente serem colocados em relação. O desenho é visto como uma linguagem propícia a contaminações, pela sua história, seus materiais e pelas qualidades de registro, intimidade e inacabado que se ligam a ele. Desenhar é uma maneira de conhecer e entender visualmente o mundo, mas também de guardar essas percepções – possibilidade que é aqui reforçada pelo uso da colagem. O encontro que acontece entre os fragmentos que constituem o trabalho é visto como um potencial de construção poética das imagens e a tese desenvolve-se em torno da hipótese de que o sentido é construído mais nas relações estabelecidas entre os componentes de um trabalho ou série, do que nas suas unidades. Isso implica que os esforços de aproximação empreendidos pela colagem preservam algo de fragmentado. Por meio da prática artística, da observação e análise reflexiva do próprio processo de trabalho e suas relações com o campo da arte, a pesquisa desencadeou reflexões acerca dos fundamentos do desenho e da colagem; dos documentos de trabalho, a coleção e a bricolagem; das estratégias de apropriação e operações de transportes de imagens. Por fim, considerando que o encontro também implica em uma distância, no contexto desta pesquisa reforça-se a busca pela não dissimulação das emendas, pela evidência do corte e da sua cicatriz. Tem-se a borda como metáfora da descontinuidade e da fragmentação características de trabalhos elaborados por meio da montagem.
The research named Aproximação de fragmentos capturados: uma poética em desenho e colagem (Approximation of captured fragments: a poetic in drawing and collage) is a poetic study based in drawing, which begins by collecting captured elements in order to later correlate them. Drawing is seen as a language vulnerable to contamination, which can be due to its history, its materials and the quality of its records, the intimacy and the unfinished that connect to it. To draw is a way to visually recognize and understand the world, but also to keep these perceptions – a possibility that is reinforced in this study using collage. The encounter of the fragments in this study is seen as a potential image poetic construction, in which this thesis is developed around the hypothesis that meaning is built in established relationship among the components of a work or series rather than in its units. This implies that the approximation efforts of the collage preserve a fragment trace. Through the practice of art, the observation and the reflexive analysis of the work process and its relationship to the art field, this research initiated reflections on the drawing and collage fundamentals; work documents; the collection and bricolage; appropriation strategies and operations of image transportation. Finally, considering that the encounter also implies distance, this research reinforces the search for a non-dissimulation of the seam, evidencing the cut and its scar. The border is a metaphor of discontinuity and fragmentation, which are characteristics of works elaborated through montage.

This research aimed to identify the procedures required for nature trails in forested areas´ deployment and management, considering benefits and problems of its use in small farms. Through literature review and empirical studies, it was possible to survey the methods and techniques of deployment, use and management of trails in forested areas, and to evaluate physical and environmental conditions, the user profile and interpretative activities in two ecological trails located in a small farm open to visitors, called Recanto Renascer, located in the municipality of Francisco Beltrão, state of Parana, Brazil. To assess the impact on the trails, the methodology Monitoring the Impact of the Visitation (IVM) was used. For the analysis of the attractiveness of each track, we used the methodology of Interpretative Attractiveness Index Points (IAPI). Soil analysis for verification of soil compaction on the trails were also done. The results obtained from the research used to develop proposals for physical- environmental and interpretive adequacy of the two tracks of Recanto Renascer, beyond the preparation of a material with technical information to owners of farms interested in establishing nature trails or in adapting existing trails.
Esta pesquisa teve como objetivo principal conhecer os procedimentos necessários para a implantação e manejo de trilhas ecológicas em áreas florestais, considerando benefícios e problemáticas de seu uso em pequenos estabelecimentos rurais. Através da revisão bibliográfica e dos estudos empíricos realizados, foi possível fazer um levantamento dos métodos e técnicas de implantação, uso e manejo das trilhas em áreas florestais, além de avaliar as condições físico-ambientais, o perfil dos usuários e as atividades interpretativas desenvolvidas em duas trilhas ecológicas localizadas em um pequeno estabelecimento rural aberto à visitação, denominado Recanto Renascer, no município de Francisco Beltrão-PR. Para o levantamento dos impactos nas trilhas, foi utilizada a metodologia Monitoramento do Impacto da Visitação (MIV). Para a análise dos atrativos de cada trilha, utilizou-se a metodologia Índice de Atratividade de pontos Interpretativos (IAPI). Também foram realizadas análises de solo, para verificação da compactação dos solos nas trilhas. Os resultados obtidos com a pesquisa permitiram desenvolver propostas de adequação físico-ambiental e interpretativa das duas trilhas do Recanto Renascer, além da elaboração de um material técnico-informativo destinado a proprietários de estabelecimentos rurais interessados em implantar trilhas ecológicas ou adequar as já existentes.

Der volle Inhalt der QuelleA Floresta Atlântica do Nordeste do Brasil contém milhares de fragmentos de florestas em diferentes estágios de regeneração, alguns se recuperando de campos agrícolas abandonados, enquanto outros se recuperam de distúrbios crônicos como incêndio, extração de madeira e caça furtiva. Alguns desses fragmentos ficaram protegidos por várias razões: responsabilidade corporativa, cumprimento do código florestal, preservação da biodiversidade, entre outros. Embora estes fragmentos estejam longe de ter a mesma riqueza de espécies vegetais e animais, podem desempenhar importantes serviços ecossistêmicos, como proteção de corpos d\'água, reservatório de importantes nutrientes e carbono. Isso é especialmente importante se considerarmos que há iniciativas globais como o REDD+ que visam avaliar florestas secundárias e de recuperação como importantes reservatórios de carbono (C). Por outro lado, a gestão e preservação destes fragmentos dependem de um conhecimento sólido sobre a sua estrutura e ciclo de nutrientes. Há uma literatura relativamente rica sobre a perda de biodiversidade nestes fragmentos florestais do Nordeste. No entanto, muito menos está disponível sobre a estrutura e o funcionamento destes fragmentos. Este trabalho pretende contribuir para o preenchimento desta lacuna, fornecendo informações científicas sólidas sobre quatro áreas florestais e uma floresta secundária, onde foi implantado um programa de restauração no Estado de Alagoas, Nordeste do Brasil. Após uma breve introdução, o capítulo um discute a estrutura desses fragmentos através de um inventário florestal completo, onde a densidade indivíduos, sua altura e diâmetro à altura do peito (DAP) foram medidos para cada árvore com DAP >= 10 cm. Com esses dados alométricos, estimamos a área basal e a biomassa viva acima do solo (AGLB), comparando esses atributos com outras estimativas disponíveis na literatura. No capítulo dois, investigamos a distribuição de nutrientes nos fragmentos florestais, onde medimos a concentração foliar de C, nitrogênio (N) e fósforo (P). Ao mesmo tempo, medimos durante um ano a massa da serapilheira em cada fragmento e seu teor de nutrientes. Com essas informações pudemos estabelecer como essas áreas ciclam seus principais nutrientes limitantes e C. Finalmente, no último capítulo abordamos a partição dos estoques de C e nutrientes, acima e abaixo do solo, com o objetivo de avaliar a importância dos pools de C e nutrientes nos fragmentos de floresta e entender qual o papel desses fragmentos em um mundo que necessita urgentemente estocar C em um reservatório sustentável.

Der volle Inhalt der QuelleConcentrated on seventeen fragments of the archaic Greek melic poetry (end of 7th to the middle of 6th centuries B.C.), this work consists in the study of Aphrodites representation in the songs of Alcman, Alcaeus, Stesichorus, Ibycus and Anacreon. Thus, the present graduation thesis gives sequence to the Masters dissertation that has already been published as a book, and in which fourteen melic fragments of Sappho (c. 630 - 580 B.C.) are studied according to the same approach. Now, in this work, the goddesss portrait is even more enhanced in its multiple aspects, despite being fragmented, and inserted in one of the most important genres of ancient Greek literature set within a specific historic period. In the effort to apprehend the movements executed in the drawings of Aphrodite by the five poets in the corpus of this thesis, I have favored the interpretative analysis of the fragments without overlooking the elements originated from other poetic genres, iconographic tradition and extra-literary records. By doing so, I have attempted to overcome, as much as possible, the precariousness of the material, somewhat more or less evident in the fragmented songs, and to understand in-depth a divine character that is not confined to poetry, but pertains to other artistic genres, as well as to Greek history and religion.

Der volle Inhalt der QuelleEcossistemas florestais dispersos em matrizes de savana da Amazônia vêm sofrendo vários tipos de impactos antropogênicos, em especial fogo recorrente e extração seletiva. O estoque de carbono na biomassa destes sistemas e a sua contribuição como mitigador dos impactos gerados pelo aquecimento global são pobremente conhecidos. O objetivo deste estudo foi estimar a biomassa arbórea viva acima do solo em ilhas de mata (fragmentos florestais) antropizadas da savana de Roraima, norte da Amazônia Brasileira. Foram avaliados os seguintes fatores: dimensão do fragmento, estrutura florestal (tomando como base a posição no gradiente: borda e interior) e as características físicas e químicas do solo. Foi realizado um inventário florestal em 12 ilhas de mata escolhidas aletoriamente, levando em consideração três categorias dimensionais (k = 3): ilhas grandes (20-60 ha), médias (10-20 ha) e pequenas (< 10 ha). Em cada categoria foram estudadas quatro ilhas (n = 4) e, em cada ilha foram estabelecidas subparcelas (76 no total). Todos os indivíduos arbóreos com diâmetro à altura do peito (DAP) ≥ 10 cm foram inventariados. A altura total de cada indivíduo foi estimada visualmente. O cálculo da biomassa arbórea viva acima do solo (AGB) para todos os indivíduos inventariados foi realizado pelo método indireto a partir de uma equação alométrica. Foram observados 1087 indivíduos de 112 espécies arbóreas (incluindo morfoespécies) pertencentes a 29 famílias botânicas. Pouteria surumuensis Baehni (Sapotaceae) foi a espécie mais abundante em todas as categorias dimensionais. Ilhas de maior dimensão possuem maior abundância de espécies de crescimento tardio e clímax, enquanto espécies pioneiras predominam em ilhas de menor dimensão. A biomassa arbórea não diferiu entre a borda e o interior dos fragmentos, independente da dimensão. Contudo, a biomassa arbórea para fragmentos grandes (469,9 Mg ha-1), médios (357,1 Mg ha-1) e pequenos (206,4 Mg ha-1) diferiu significativamente (ANOVA; Tukey0,05), indicando que fragmentos maiores possuem maior AGB. A biomassa arbórea viva não apresentou relação com as características físicas e químicas do solo. A conclusão deste estudo é que biomassa arbórea viva acima do solo das ilhas de mata da savana de Roraima varia em função da dimensão do fragmento, mas independe da posição no gradiente (borda interior), não indicando relação significativa com estrutura física ou fertilidade do solo.
Forest ecosystems dispersed in matrices of Amazonian savannas have been suffering many types of anthropogenic impacts, in particular recurrent fire and selective logging. The carbon stock in the biomass of these systems and its contribution to mitigation of impacts generated by global warming are poorly known. The aim of this study was to estimate the living above ground biomass in anthropized forest islands (forest fragments) in the Savanna of Roraima, Northern Brazilian Amazon. Environmental factors were evaluated: the fragment dimension, forest structure (based on the position in the gradient: edge and interior) and the physical and chemical soil characteristics. A forest inventory was carried out in 12 forest fragments randomly chosen, taking into account three-dimensional categories (k = 3): large islands (20-60 ha), medium (10-20 ha) and small (< 10 ha). In each category were studied four fragments (n = 4) and in each fragment subplots were established (76 in total). All individuals with tree diameter at breast height (DBH) ≥ 10 cm were inventoried. The total height of each individual was estimated visually. Living above ground biomass was calculated for all individuals inventoried using indirect method (allometric equation). One thousand and eight seven (1087) individuals were observed of 112 tree species (including morphospecies) belonging to 29 botanical families. Pouteria surumuensis Baehni (Sapotaceae) was the most abundant species in all dimensional categories. Forest islands with larger dimensions have higher abundance for both late-growing and climax species, while smaller islands were dominated by pioneer species. The living above ground biomass did not differ between the edge and the interior of fragments regardless of dimension. However, the forest biomass of large (469.9 Mg ha-1), medium (357.1 Mg ha-1) and small (206.4 Mg ha-1) fragments differed significantly (ANOVA; Tukey0.05), indicating that larger fragments have higher living above ground biomass. The living above ground biomass did not present any relationship with the physical and chemical soil characteristics. The conclusion of this study is that living above ground biomass of forest islands in the Savanna of Roraima varies depending on the fragment size, but is independent of the position in the gradient (edge-interior), indicating no significant relationship with the structure or soil fertility.

Resumo: Os Euglossini distribuem-se exclusivamente na região neotropical. Os machos são facilmente atraídos por terpenóides e hidrocarbonetos aromáticos sintéticos, análogos àqueles presentes nas fragrâncias florais. Essa técnica tem auxiliado no conhecimento da fauna de diferentes áreas biogeográficas, revelando novas espécies. Nos últimos anos, a preocupação crescente com a perda de biodiversidade em seu sentido mais amplo vem se manifestando entre os pesquisadores que estudam aspectos da biologia e ecologia de abelhas, em grande parte, pelo reconhecimento da forte dependência de espécies de plantas cultivadas e nativas em relação às abelhas para a polinização. A habilidade dos Euglossini de se dispersarem e encontrarem flores isoladas e iscas aromáticas distantes tem levado à sugestão de que as abelhas atraídas para as fragrâncias vem de uma vasta área que pode incluir diferentes habitats. Este trabalho teve por objetivos: (1) Conhecer a composição e a diversidade de espécies, a fenologia e o uso de habitats da comunidade de Euglossini de uma área composta por fragmentos de Mata Atlântica, de diferentes tamanhos, em Jacutinga, Sul de Minas Gerais. (2) Avaliar o padrão de deslocamento das diferentes espécies entre esses fragmentos. Abelhas Euglossini foram coletadas em quatro fragmentos de diferentes tamanhos e diferentes graus de degradação na Serra da Forquilha, município de Jacutinga, MG com auxilio de iscas aromáticas. As coletas foram realizadas mensalmente, no período de abril de 2007 a março de 2008. Para analisar a similaridade entre as estações, foi utilizado o Coeficiente de Correlação de Pearson e a Análise Multivariada Conglomerada. A diversidade de espécies foi avaliada por meio dos índices de Shannon - Winner e Índice de Simpson.. Foram coletados 1778 machos de Euglossini, pertencentes a quatro gêneros e dez espécies.

Abstract: The orchid bees are distributed exclusively in the Neotropics. The males are easily attracted by terpenoids and aromatic hydrocarbons, synthetic analogs to those found in floral fragrances. This technique has helped in the knowledge of fauna from different biogeographic areas, revealing new species. In recent years, the growing concern over the loss of biodiversity in its broadest sense has manifested itself among researchers who study aspects of biology and ecology of bees in large part by the recognition of the strong dependence of species of cultivated and native plants in relation to bees for pollination. The ability of orchid bees to disperse and find isolated flowers and scented baits far has led to the suggestion that bees attracted to the fragrance comes in a vast area that may include different habitats. This study aimed to: (1) Know the composition and species diversity, phenology and habitat use of community Euglossini an area composed of Atlantic forest fragments of different sizes, Jacutinga, South of Minas Gerais. (2) To assess the pattern of displacement of various species between these fragments. Euglossini were collected in four fragments of different sizes and different degrees of degradation in Mountain Fork, City of Jacutinga, MG aromatic with the aid of bait. Samples were collected monthly between April 2007 and March 2008. To analyze the similarity between the stations, we used the correlation coefficient of Pearson and Multivariate Analysis Conglomerate. Species diversity was assessed by the Shannon - Winner and Simpson index. We collected 1778 male orchid bees, belonging to four genera and ten species. The most abundant species were Eulaema nigrita, Euglossa annectans, Eufriesea violacea and Euglossa truncata. Eucalyptol was more efficient scented bait attracting 49.6% of males of all ten species. The largest number of males was collected in hot and humid season... (Complete abstract click electronic access below)

O presente trabalho analisa de que maneira as reflexões teórica sobre a criação poética de Novalis, que se materializam nos fragmentos de Pólen, relacionam-se com os poemas que compõem os Hinos à Noite. Procuramos analisar a relação dialética que as duas obras estabelecem que consiste no fato dos fragmentos possuírem características da poesia e de suas ideias estarem presente nos poemas. Analisamos os fragmentos que refletem sobre as teorias românticas acerca da poesia e do poético, compreendendo como se constitui nessa obra o pensamento crítico de Novalis sobre poesia e linguagem, estabelecendo, depois, ligações com os poemas, associando a reflexão crítica presente em Pólen com alguns elementos poéticos marcantes nos Hinos como o misticismo, a ideia de conhecimento, o símbolo, a valorização da Noite, da Morte e do Amor. Compreendemos que as duas obras estabelecem uma conexão de ideias, pois, entendemos os Hinos como uma poesia transcendental, sobre a qual Novalis teorizou em seus fragmentos, além disso, analisamos que os símbolos do Amor e da Morte estão presentes em ambas as obras e são construídos a partir de características em comum. Refletimos ainda que as duas obras se aproximam também no aspecto formal, uma vez que em ambas Novalis faz experimentações formais: em Pólen temos o desenvolvimento do fragmento como gênero, enquanto nos Hinos temos o poema em prosa e em verso. Verificamos, então, que Novalis dissolve as fronteiras entre poesia, teoria e crítica, tanto em relação as reflexões propostas e a linguagem utilizada quanto a composição formal, criando, com isso, uma maneira original de se pensar e se produzir as obras literárias, suas teorias e suas críticas.
The present work studies the way the theoretical reflection about the poetic creation of Novalis, that are present in the fragments of Pollen, have a relation with the poems of the Hymns to the Night. We analyze the dialectics relation that the two works have, which is the fragment having characteristics of poetry and the ideas of the fragments being present in the poems. We analyze the fragments that reflect the romantic theories about poetry and poetic, understanding how the critical thoughts by Novalis about poetry and language are made, establishing, after that, connections with the poems, and linking the critical reflection that’s in Pollen with some important poetic elements of the Hymns, as the mysticism, the idea of knowledge, the symbol, the valorization of Night, Death and Love. We recognize that the two works have a connection of ideas, because we understand the Hymns as the transcendental poetry, that Novalis theorized in his fragments. Furthermore, we analyze that the symbols of Love and Death are in both works and made with sharing characteristics. We also reflect that both works have similarities in the formal aspect, once that in both Novalis make formal experimentations: in Pollen we have the development of the fragment as a genre, and in the Hymns the poem in prose and verse. We also verified that Novalis dissolves the frontiers among poetry, theory and criticism, in relation to the proposed reflections and the language used as well as the formal composition, creating, with this, a new way of thinking and producing the literary compositions, their theory and their criticism.

Der volle Inhalt der QuelleAtualmente, a cidade de Lisboa encontra-se sujeita a um forte desenvolvimento. Este, por sua vez, demonstra cada vez mais a sua saturação, pelo que é eminente a expansão deste desenvolvimento para a periferia, na procura de novas centralidades. Muito devido à sua relação com o rio, a frente ribeirinha oriental de Lisboa vai decerto ser engolida por esta expansão. O recente passado industrial vivido nesta área esquecida da capital deixou para trás inúmeros espaços expectantes, dos quais a cidade procura agora apropriar-se. O Vale de Chelas / Xabregas, apontado como novo corredor verde oriental confronta-se com esta responsabilidade, devido à sua proximidade com o centro e a sua história. Surge a oportunidade de intervenção, uma proposta urbana de carácter regenerativo que ao mesmo tempo provoca ligações com o resto da cidade. Para garantir esta nova vida do vale é importante intervir sobre elementos, agora obsoletos, fulcrais à regeneração urbana. É perpetuada a memória destes fragmentos, cidade e património.
ABSTRACT: , more and more its saturation, it is eminent its expansion to the periphery in the search for new centralities. Much owing to its relationship with the river, the eastern riverfront of Lisbon is bound to be swallowed up by this expansion. The recent industrial past lived in this forgotten area of the capital left behind numerous expectant spaces, which the city now seeks to take ownership. The valley of Chelas / Xabregas, designated as the new eastern green corridor, is confronted with this responsibility, due to its proximity to the center and its history. The opportunity for intervention emerges, an urban proposal of a regenerative nature that at the same time causes links with the rest of the city. To guarantee this new valley life, it is important to intervene on now obsolete elements that are crucial to the urban regeneration. It is perpetuated the memory of these fragments, city and heritage.

Therefore, this work assessed if the management of superabundant heliophytic climbers could favor the growth and density of natural regeneration in degraded forest fragments, justifying climber management as strategy of ecological restoration. The research was conducted in a 14 ha Seasonal Semideciduous Forest fragment in Piracicaba-SP. We allocated in these fragment 25 permanent plots and, for part of these plots, we managed superabundant climbers at the canopy and, in a smaller proportion, in the understory. We used these plots to understand the management effects in different regeneration phases: seed bank, seedling establishment, growth and survival of saplings. For data analysis, in each plot we evaluated in the beginning of the experiment and one year after management interventions, when we evaluated the composition, density and height of shrub and tree species individuals for two size classes (dbh> 1,58 cm; height >= 10 cm and dbh <= 1,58 cm), and density, height and basal area of regenerating climbers. Then we evaluated the proportion of climbers, shrubs and trees in the seed bank, for seedlings established 1 year after management interventions and, lastly, the effect of climber management in the community composition, density, height and basal area. A higher density of tree and shrub species were only found in seed bank, while climbers were more abundant in the following regeneration stages. The management of climbers in the canopy increased the growth of tree and shrubs saplings and climber mortality, but climber recruitments increased. Overall, climber management increased climber mortality and favored tree and shrub saplings growth, highlighting the importance of managing climbers in degraded fragments. However, the high regeneration capacity of climbers after management reinforce the need of permanent management. Thus, our results support the management of climbers, which is needed until the canopy is close enough to reduce the recolonization of climbers.

Der volle Inhalt der QuelleTuberculosis (TB) is an important infectious disease and presents critical factors such as the relationship with HIV / AIDS, long treatment and resistance to multiple drugs. The enzyme dihydrofolate reductase from mycobacteria (mtDHFR) is a poorly explored and presents great potential to be a target for new drugs against TB. Preliminary studies have obtained fragments with low affinity to mtDHFR, but with potential to become lead compounds. Therefore, the fragment was used as a prototype for 22 analogues proposed in this work. The compounds were designed using bioisosterism, information about ligands and the three-dimensional structure of mtDHFR. Molecular docking assays with mtDHFR revealed satisfactory scores for anlogues. Furthermore, the insertion of substituents seemed to increase the affinity with the enzyme. Thereby, twenty two analogues and prototype were synthesized using alkylation, hydrolysiss and 1,3-dipolar cycloaddition methods. The compounds were obtained in good yields (60 ~ 90%) and their structures were elucidated with 1H and 13C NMR spectroscopy. The enzymatic affinity assay corroborates docking results, because the presence of carboxyl group showed to be important for the activity. Furthermore, some of the compounds revealead interesting activities, ranging 8 to 40 µM. The most active showed IC50 of 7 µM and enzyme kinetics assays indicated noncompetitive inhibition with natural enzyme substrate. The synthesized analogs were sent for in vitro assay to assess mycobacteria activity.

Der volle Inhalt der QuelleChagas disease is a parasitic illness endemic in Latin America caused by the trypanosomatid parasite Trypanosoma cruzi that spreads around the world due to people migration. Nowadays, Benznidazole and Nifurtimox (banned in Brazil), are used for the treatment of this disease but causes severe side effects to patients. Recently, three new molecules have reached clínical trials phase in the development of drugs against Chagas disease but it is still necessary to develop new drugs. In this studies, the enzyme Glyceraldehyde-3-phosphate Dehydrogenase (GAPDH) was used as a target for the search of new antitrypanosomatid molecules. It belongs to the glycolytic pathway, the major one for parasite\'s energy generation. With the aim searching a new molecule that inhibits this enzyme, the fragment-based approach guided the search of molecules with high ligand efficiency. A focused compound library was assembled from a database of 500,000 molecules using molecular and solubility filters and the Rule of Three. The integrated use of ligand (chemical and electrostatic similarity) and target (molecular docking) based drug design was carried out to rank the molecular fragments by a consensual score. Through visual inspection of the top 500 molecules five diverse fragments were selected for the in vitro enzymatic assays using fluorescence spectroscopy. One of these molecules shows a Ki equals to (425 ± 53) μM and ligand efficiency equals to 0,33, a promising value for the fragment-based approach. Additionally, Molecular Dynamics simulations (MD) were carried out with these fragments and the predicted energy of interaction for fragment-enzyme complex was able to rank the molecules as using the experimental results. Furthermore, the MD was useful to predict the mode of interaction of the fragments in the active site of enzyme and to reveal a new cavity close to the substrate binding site. A second generation of compounds was selected based on the structure of the active fragment to construct theoretical structure-activity relationship (SAR) using MD. SAR indicates that the presence of a nitrogen with hydrogen-bond donor property is important to the interaction, making hydrogen-bonding with the amino acid residue Asp210. In addition, MD shows the influence of different substituent posítion in the central ring in the energy of the interaction, with a 2,3 substitution at five-atom ring the most favorable. This study identifies the first molecular fragment with high ligand efficiency for the enzyme TcGAPDH, with the combined use of ligand and target-based tools and fluorescence spectroscopy, for selection and identification of active compounds against the enzyme. MD was able to reproduce experimental results and generate theoretical information of SAR to the active molecular fragment.

Der volle Inhalt der QuelleSOFIA (Studies On FIssion with Aladin) is an innovative experimental program which aims to measure several fission observables — the isotopic fission yields, the total kinetic energy of the fragments and the prompt neutron multiplicity, for a wide range of actinides and pre-actinides. The use of inverse kinematics (the fissioning system is the beam instead of the target) is the only way to fully identify fragments in charge and mass. The PhD work presented in this thesis concerns the experiment conducted in October 2014, and is focused on the Coulomb-induced fission of ² ³ ⁶ U, which can be regarded as the analog of the neutron-induced fission of ² ³⁵U.The SOFIA experiments take place in GSI (Darmstadt, Germany) because it is the sole facility in the world which delivers a beam of ² ³⁸U at 1 AGeV. This beam is fragmented and the products are selected by the FRS (FRagment separator) in order to deliver a secondary beam of nuclei of interest - ² ³ ⁶ U in our case, which is then guided to the SOFIA setup where its fission is triggered.Since some nuclides with close atomic and mass numbers to ² ³ ⁶ U are also transmitted by the FRS, it is necessary to identify the fissioning system from the secondary beam first, and then identify both the associated fission fragments. All identifications are performed event by event on the basis of measurements of the energy loss, the magnetic rigidity and the time of flight. Since we are only interested in the Coulomb-induced fission of ² ³ ⁶ U, the contribution of fragmentation fissions on the nuclear charge distribution of fission fragments has to be suppressed.The analysis in this paper involves the isotopic identification of the fissioning system, the nuclear charge identification of the fission fragments, the estimation of the nuclear contribution, and the extraction of the elemental fission yield. The results are then compared to other measurements performed with the SOFIA setup, as well as previous results obtained by other techniques

Der volle Inhalt der QuelleThis writing goes through the ink of painting through its own. It has this body to share, both fraternal and irreconcilable. Here the ink of writing sought to pave a liquid way in painting, giving to its movement the trembling of color, which is a gesture of matter itself. As for my gesture, drunk by the paper and withdrawn in folds of waves, operates a drift to the white of a page on the table, that unfolds to this singular object that is the thesis in fine arts. In fact, as painting accompanies in its shadowy wake the questioning of a gaze, its course without outline, writing from painting, turns on its own object - from one ink to another. The construction of a discourse in touch with the wandering of the studio is delicate. It merges its body resonant with images with that of words from poets, working an unknown language in the very core of the impasse that constitutes words, access to speech. The painter's voice is the only one I know. It is the result of the abandonment and divestment at work. It engages thought in making, in the midst of a deposition which is, multiple, that of a body of ink, of a radiant painting, of a gesture and its removal, of a voice and its fragments. Deposition calls for the ground. It is that very ground that is being discussed throughout this writing. A grounding, as foundation but also as what melts under the steps. Liquid, fluid, moving. A release that is also an anchor, a tie that is also an overflow
