Questo lavoro si propone di analizzare attraverso lo studio di tre dei più importanti canzonieri rinascimentali inglesi - "Astrophil and Stella" di Philip Sidney, i "Songs and Sonnets" di John Donne e i "Sonnets" di William Shakespeare - il concetto di eros maschile e quindi l’espressione del desiderio fisico nella sua manifestazione esplicita o implicita all’interno dei numerosi testi che compongono queste tre raccolte poetiche, mettendo in luce non solo la pluralità dei significati che esso assume nella cultura e nella mentalità inglese dell’epoca, ma cercando anche di esplicitare quelle considerazioni e/o valutazioni che emergono, con minore e maggiore rilevanza, dal confronto dei più disparati punti di vista, a vari livelli d’interpretazione testuale. Un’indagine alla scoperta della plurivocità e dei registri linguistici del codice d’amore: la seduzione verbale, l’esibizionismo maschile, le forme dell’osceno in contrapposizione al platonismo estetico della bellezza ideale e della "cuncupiscientia animae". Simmetria e senso dei ruoli intra-testuali: l’auto-rappresentazione del poeta, la costruzione della persona amata come oggetto ideale del desiderio fisico, e il voyeurismo del lettore. / The main purpose of this research is to analyze three of the major lyric collections of the English Renaissance – "Astrophil and Stella" of Philip Sidney, the "Songs and Sonnets" of John Donne and the "Sonnets" of William Shakespeare – focusing attention on the representation of male eros and the physical desire, as conceived and expressed (in all their explicit or implicit manifestations) in the poetical compositions of the three chansonnieres. In this sense we wish to throw a new light upon the variety of meanings which male eros and the physical desire assume in the English culture and in the mentality of that age, and to make also clear all those aspects and/or assessments which (with more or less relevance) come out at different levels of textual interpretations from the comparison of the most diverse points of view. The inquiry has been oriented to the discovery of the multi-voiced components and to the analysis of the several registers of the code of love: the study of verbal seduction, male exhibitionism, obscene language in contrast with the aesthetic Platonism concerning the idealized beauty and cuncupiscientia animae. Sense and symmetry of textual roles: the self-representation of the poet, the outline of the beloved figure, and the voyeurism of the reader.

“Irony, Finitude and The Good Life,” examines the notion that Socrates, as he is portrayed in the Platonic dialogues, ought to be viewed and interpreted as a teacher. If this assertion is correct, then it is both appropriate and useful to look to the dialogues for instruction on how to live a philosophical life. This thesis will argue that to look at Socrates as a teacher, a figure who imparts knowledge to those around him on how to live a philosophical life, misses the very conception of the good life that Plato sought to personify when he created the character of Socrates. The proceeding discussion draws upon the work of Alexander Nehamas and Drew Hyland, offering an alternate interpretation of the Symposium. This interpretation argues that viewing Socrates as a teacher falsely idealizes the philosophical life, in turn neglecting Plato’s greater legacy for his character—a legacy in which true virtue lies in exposing the creative possibility inherent in living a philosophical life and prompting one’s own expression of a life inspired by the legacy of Socrates.

The intent of this thesis is to catalogue and seek to understand why we desire what we desire and how this desire is transcribed onto the landscape. Applying this knowledge can be used to assist landscape architects through the design process by understanding the complex systems that interact to define I and We. Questions of concern to this thesis can be summarized as; • Is the theory that our desires affect the designs of landscape architects tenable? • Can this theory be implemented? • And, if so, to what degree?

By framing his deconstruction of Plato’s Phaedrus and Timaeus as a response to Platonism, Jacques Derrida overlooks the possibility of a Platonic philosophy beyond dogma and doctrine. This thesis argues that Derrida’s deconstructions target a particularly Platonist abstraction of the dialogues, and thus, his critique relies on the underlying assumption that Plato defends the metaphysics of presence. Derrida attempts to show how the thesis that Being is presence undermines itself in both dialogues through hints of différance like pharmakon and khôra. To answer the Derridean critique, I analyze the hermeneutics of Derrida’s deconstruction of Plato and identify what in the dialogues lies beyond the limits Derrida’s reading, for example Derrida’s notable exclusion of ἔρως.

Once extracts from this plant are used for acceleration of scar s process, it is important to study their mutagenic and genotoxic potential. In previous works in our laboratory, it was observed mutagenicity caused by the decoction when in high concentrations. Among the chemical compounds of this plant that could be able to induce mutation, the flavonoids were the only group that was referred to have either an oxidant or antioxidant potential. The flavonoids were isolated, purified and quantified by adsorptive column chromatography under silica gel, bacterial and in vitro genotoxic tests were realized to determine if the flavonoids were the responsible agents for this mutagenicity found. The tests realized with plasmidial DNA were indicative that the flavonoids are probably genotoxic, due to the presence of correlation between increase of the flavonoid concentration and in plasmidial DNA double strand breakage visualized in agarose gel, as well as they were capable to generated abasic sites shown by the in vitro treatment with exonuclease III. The same tests with plasmidial DNA in the presence of copper [10 ?M] and of a Tris-HCl pH 7.5 [10 ?M] buffer were realized with the isolated flavonoids to determine if there would be or not participation of reactive oxygen species (ROS). The transformation of plasmidial DNA in different bacterial strains proficient and deficient in DNA repair enzymes in the presence or not of a Tris-HCl buffer, suggests that the enzymes that repair oxidative lesions are necessary to repair the lesions generated by the flavonoids and that ROS are generated and are necessary to promote the lesions. Bacterial tests with Escherichia coli strains of the CC collection (deficient or not for DNA repair enzymes), showed that the flavonoids are able to increase the frequency of mutations, mainly in strains mutated in repair enzymes (MutM, MutY-glicosylases and double mutant), suggesting that these agents are responsible for the enhancement in the mutation rate. In order to determine the mutation spectrum caused by the flavonoids of the Brazilian pepper tree stem bark, plasmidial DNA previously treated with the flavonoids were transformed in bacterial strains deficient and proficient in the DNA repair enzymes, followed by a blue-white selection with X-gal, DNA amplification by PCR and sequencing the positive mutant clones. Analysis of the mutants obtained from strains CC104, CC104mutM, CC104mutY, CC104mutMmutY, BW9101, BW9109 indicated a predominance of some mutations like G:C to C:G that can be correlated with the origin of 8-oxoG, due to oxidative lesions caused by the flavonoids. So it can concluded that the flavonoid isolated or in fractions enriched on them are genotoxic and mutagenic, and their mutations are predominantly oxidative, mediated by ROS, and the lesions are recognized by the BER system. In this way it is proposed that the flavonoids can act in two different ways to generate the DNA lesion: 1. in a Fenton-like reaction, when the flavonoid are in the presence of metal ions and that together with the water generate ROS that promotes the DNA lesions; 2. in another way the lesions can be generated by the formation of ROS due to the internal chemical structure of the flavonoid molecule due to the quantity and location of hydroxyl groups, and so producing the DNA lesions, those lesions can be directly (suggested by the in vitro experiments) or indirectly done (supported by the experiments using the CC bacterial strains) / O decocto feito de cascas da Aroeira (Schinus terebinthifolius, Raddi) ? usado na medicina popular como cicatrizante e anti-inflamat?rio, mas, apesar de seu efeito medicinal, tamb?m foi demonstrado um efeito mutag?nico. O objetivo deste trabalho foi determinar se os flavon?ides da aroeira s?o os respons?veis pela mutagenicidade bem como propor um mecanismo de a??o. Para tanto, diferentes fra??es enriquecidas em flavon?ides foram preparadas e os flavon?ides foram isolados, purificados e quantificados via cromatografia de adsor??o em gel de s?lica. Testes de genotoxicidade, in vitro e em sistemas bacterianos foram realizados a fim de determinar o mecanismo de a??o. Testes realizados com DNA plasmidial In vitro foram indicativos de que as fra??es enriquecidas de flavon?ides s?o capazes de gerar dupla quebra na fita do DNA, bem como s?o capazes de gerar s?tios ab?sicos, evidenciados na presen?a da exonuclease III. O mesmo teste com DNA plasmidial, mas na presen?a de cobre [10 ?M] e de tamp?o Tris-HCl pH 7.5 [10 ?M], foi realizado, para determinar se haveria ou n?o participa??o de esp?cies reativas de oxig?nio na indu??o de danos. A transforma??o do DNA plasmidial em diferentes cepas bacterianas, proficientes e deficientes em diferentes vias de reparo de DNA, na aus?ncia e presen?a de tamp?o Tris-HCl pH 7.5 [10 ?M], sugerem que enzimas de reparo de les?es oxidativas s?o necess?rias para reparar as les?es geradas pelos flavon?ides e que esp?cies reativas de oxig?nio s?o geradas e necess?rias para promover as les?es. Teste de mutagenicidade direta com diferentes cepas de Escherichia coli derivadas da linhagem CC104 sugeriram que os flavon?ides aumentam a freq??ncia de muta??o em cepas deficientes nas enzimas MutM e MutY glicosilases, principalmente na duplo mutante, sugerindo que as les?es predominantemente oxidativas, s?o substratos destas enzimas no DNA. A fim de determinar o espectro de muta??o causado pelos flavon?ides da aroeira, DNA plasmidial foi transformado previamente tratado com as fra??es enriquecidas em flavon?ides em cepas deficientes em enzimas de reparo de DNA, seguido de sele??o por colora??o com x-gal (sele??o azul-branco), amplifica??o de DNA por PCR e sequenciamento dos clones mutantes. An?lise dos mutantes obtidos nas cepas CC104, CC104mutM, CC104mutY e CC104mutMmutY indicaram a predomin?ncia de muta??es do tipo G:C para C:G, que pode estar correlacionada a origem de 8-oxoG, devido a les?es oxidativas causadas pelos flavon?ides. Assim, pode-se concluir que os flavon?ides isolados ou em fra??es enriquecidas nos mesmos s?o respons?veis pelo potencial mutag?nico dos extratos da aroeira, que as les?es geradas s?o oxidativas, predominando a forma??o de 8-oxoG, devido ? forma??o de EROs, e que s?o reconhecidas por enzimas do sistema de reparo por excis?o de base. Desta forma, prop?e-se que os flavon?ides possam gerar esp?cies reativas de oxig?nio de duas maneiras diferentes: i) em uma rea??o Fenton-like, quando os flavon?ides est?o na presen?a de metais e ?gua ou ii) devido ? estrutura interna da mol?cula de flavon?ide pela disposi??o e quantidade de grupamento hidroxilas na pr?pria mol?cula. As les?es podem ser geradas diretamente (sugerido pelos experimentos de tratamento in vitro) ou indiretamente (pelos experimentos obtidos com as linhagens CC)

In this region are installed the main socio-economic activities of the State, highlighting the oil industry, which exerts much of its activities in the coastal area studied. Erosion is a constant problem in this region because it affects the entire local populace to the destruction of houses and trade, rendering tourism, affecting the livelihood activities and industrial activities. The greatest risk is related to environmental damage that can be caused by the oil spill in this region. To understand what determines the changes in coastal morphology this Doctoral Thesis is proposed to identify the factors at local, regional and even global corroborate coastal dynamics to this coast in question. For this study, used several different products and tools for interpreting the conditions of the erosive effect that dominates the whole northern coast of the State, in an attempt to quantify and describe the causes and effects that affect the entire coastal zone monitored. The development of activities is built into the projects Rede 05 PETROMAR (CTPETRO-FINEP/PETROBRAS/CNPq), PETRORISCO, HIDROSEMA, PETROMAR e Rede 05/04 POTMAR (FNDCT/CTPETROFINEP/ CNPq), in the activities of multidisciplinary and inter-features in issues involving environmental monitoring and oil activity / O litoral setentrional do Estado do Rio Grande do Norte ? caracterizado por fortes mudan?as na sua morfologia costeira, ocasionadas por diversos fatores geol?gicos e clim?ticos. Nesta regi?o est?o instaladas as principais atividades socioecon?micas do Estado, destacando a Ind?stria Petrol?fera, que exerce boa parte de suas atividades na zona costeira estudada. A eros?o ? o constante problema nesta regi?o, pois afeta toda popula??o local com a destrui??o de moradias e com?rcio, inviabilizando o turismo, comprometendo as atividades de subsist?ncia e as atividades industriais. O risco maior est? relacionado ao dano ambiental que pode ser causado pelo derramamento de ?leo nesta regi?o. Para entender o que condiciona estas modifica??es na morfologia costeira esta Tese de Doutorado se prop?s em identificar os fatores de escala local, regional e at? global que corroboram com a din?mica costeira para este litoral em quest?o. Para tal estudo foram utilizados diversos produtos e diversas ferramentas para interpreta??o das condicionantes do efeito erosivo que predomina como um todo o litoral setentrional do Estado, na tentativa de quantificar e qualificar as causas e efeitos que afetam toda zona costeira monitorada.

Essa import?ncia se torna mais evidente devido ? elevada densidade das cidades litor?neas, ? crescente especula??o tur?stico-imobili?ria dessas ?reas e ?s altera??es clim?ticas que tendem a desencadear e acelerar esses processos. Nesse contexto, percebe-se cada vez mais um aumento significativo dos problemas relacionados ? eros?o costeira e recuo de fal?sias no estado do Rio Grande do Norte. A ?rea de estudo desta pesquisa localiza-se na zona costeira do munic?pio de Ba?a Formosa/RN, no litoral oriental-sul do Rio Grande do Norte, e possui uma extens?o de cerca de 1200 m ao longo da praia do Porto. O objetivo principal deste trabalho ? analisar a estabilidade dessas fal?sias, atrav?s de investiga??es de campo, ensaios e an?lises computacionais utilizando o M?todo dos Elementos Finitos e o M?todo de Bishop. Para atender aos objetivos deste trabalho, a ?rea foi subdividida em quatro trechos, e foram aplicados checklists e tamb?m realizados ensaios de caracteriza??o e de cisalhamento direto com materiais obtidos ao longo desses trechos. Os segmentos de fal?sia nessa zona costeira possuem alturas variando em torno de 4 m e 14 m e inclina??es de aproximadamente 40? a 90?. Os solos constituintes das fal?sias foram classificados, em termos gerais, como areias argilosas ou siltosas e argilas arenosas, sendo os solos mais argilosos e variegados pertencentes ? base da fal?sia. As an?lises de estabilidade mostraram que os fatores de seguran?a variaram, no trecho 01, de 2,38 a 6,06, no trecho 02, de 1,01 a 1,62, no trecho 03, de 1,29 a 1,78, e no trecho 04, de 0,83 a 2,48. Assim, os trechos 02 e 03, foram considerados como mais inst?veis. Entretanto, pode-se considerar o trecho 03 como o mais cr?tico devido ? aus?ncia de estruturas de prote??o costeira e ? estreita faixa de praia. Fato que n?o ocorre no trecho 02, o qual possui uma extensa faixa de praia e ? protegido por um muro de arrimo que restringe o acesso dos banhistas ?s ?reas adjacentes do p? da fal?sia. / The natural and anthropogenic changes that are occurring at the coastal zone around the world represent the greatest problem to society in this century. This problem becomes more evident due to high density of coastal cities, to growing tourist-estate speculation of those areas and to climate change that tend to trigger and accelerate the erosive processes that operating in the littoral. In this context, it?s possible perceive ever more a significant increase of problems associated to the coastal erosion and retreat of cliffs in the state of Rio Grande do Norte, where this study area of this search is located. The area is located in the coastal zone of the city of Ba?a Formosa/RN, in south-eastern coast of Rio Grande do Norte, and has a extension of about 1200 meters along the Porto beach. The main objective of this study is to analyze the stability of these cliffs in this region. Through field investigations, testings and computational analysis using the Finite Element Method and Equilibrium Limit Methods. The area was divided into four sections, and were applied checklists, and also realized characterization tests and direct shear tests with materials obtained along these sections. In this manner, it was found that the segments of cliff in this coastal zone have heights around 4 meters to 14 meters and inclinations of approximately 40? to 90?.However the constituents soils of the cliffs were classified, in general terms in accordance to Unified Soil Classification System (USCS), as clayey sands or silty sands, clays of low plasticity, clayey gravels and poorly graduaded sands. The most variegated and clayey soils belong to base of the cliff. The stability analysis showed that the safety factors ranged in section 01, from 1.92 to 4.93, in the section 02, from 1.00 to 1.43, in the section 03, from 1.36 to 1.75 , and section 04, from 1.00 to 3.64. Thus, the sections 02 and 03 were considered more unstable. However, the section 03 can be considered as the most critical section due to the absence of coastal protection structures and the narrow strip of beach.
