It is assumed that a bond is created between cook and diner and that there is a discourse between them, being the food the mediator of several possible kinds of relations. Thus, emotional relations arising from these proceedings are investigated, inquiring the proposed notion: affective gastronomy. In order to work this object, experiments were performed and show that communication through gastronomy is able to affect relations. my as a non-verbal communication process and the relations established through cooking and eating togeA brief theoretical review on the peculiar relation established between human beings and food is carried out, as well as communication as an event and phenomenon that initially involves the body. The concept of ???affection??? as an important aspect of communication is investigated as proposed by Cyrulnik and Maffesoli. The notion of met??poro as defended by Ciro Marcondes is applied to bring all these aspects together. It is believed that gastronomic language is demonstrated by displays of affection. / Prop??e-se analisar a gastronomia como processo de comunica????o n??o-verbal e as rela????es que se estabelecem atrav??s da culin??ria e da comensalidade.

Several transgenic approaches have been developed to improve cotton???s resistance through the expression of different transgenes, including Cry toxins, hydrolytic proteinase inhibitors, toxic peptides, dsRNA, among others. However, transformation methods remain limited by cotton variety due to the difficulties imposed by tissue culture and the steps necessary in Agrobacterium-mediated transformation and/or particle bombardment. The pollen tube transformation technique involves the introduction of an exogenous DNA into the plant genome being independent of tissue culture. This method can be applied into different cotton cultivars and it has been used successfully in generation of Bt cotton. In Chapter 2, the pollen-tube pathway technique was used to transform a Brazilian cotton cultivar. The putative transgenic plants derived from boll seeds injected with a binary expression vector, harboring the cry1Ia12 gene were initially selected with kanamycin. Selected plants were characterized using PCR, Southern blot, Western blot and ELISA techniques to confirm the genetic transformation. Western blot and ELISA data showed variable protein expression among the transgenic plants varying from 1,?? ??g g-1 to ??,??6 ??g g-1. An insect bioassay using T1 plants revealed the entomotoxic effects of Cry1Ia12 on Spodoptera frugiperda, as evidenced by a decrease in the development of insects compared with untransformed controls. Entomotoxic effect with Anthonomus grandis was also demonstrated by a decrease in the number of emerging insect adults. In Chapter 3, the agrolistic transformation technique was used to transform the Coker 310 cultivar. The putative transgenic plants derived from transformed embryos with a vector harboring the cry8Ka5 and ??AI-C3 genes were selected in vitro, and acclimatized in a greenhouse. Acclimatized plants were characterized using PCR and ELISA techniques to confirm the genetic transformation. Collected seeds from positive plants were sown for T1 plants analysis, aiming the technique evaluation. It was observed the cry8Ka5 gene amplification, and the ELISA results showed variable protein expression between transgenic plants. It was possible to demonstrate with this work, the efficacy of GM cotton plants generation using alternative biotechnological approaches, efficiently applied to the lepidopterans and coleopterans control. / O algod??o ?? uma fonte de fibra natural de grande import??ncia econ??mica, sendo uma cultura altamente afetada por diferentes insetos-praga e pat??genos. Diversas estrat??gias de transgenia t??m sido desenvolvidas para melhorar a resist??ncia do algod??o, por meio da express??o de transgenes, incluindo toxinas Cry, inibidores de enzimas hidrol??ticas, pept??deos t??xicos, dsRNA, entre outros. No entanto, os m??todos de transforma????o ainda s??o limitados a algumas variedades de algod??o devido ??s dificuldades impostas pela cultura de tecidos e ??s etapas necess??rias de transforma????o, seja mediada por Agrobacterium e/ou bombardeamento de part??culas. A t??cnica de transforma????o via tubo pol??nico ?? uma t??cnica que envolve a introdu????o de DNA gen??mico ex??geno em plantas, sendo independente de cultura de tecidos. Este m??todo pode ser aplicado para diferentes cultivares de algod??o e tem sido utilizado com sucesso na gera????o de algod??o Bt. No Cap??tulo 2, a t??cnica de transforma????o via tubo pol??nico foi utilizada para transformar uma cultivar de algod??o brasileira. As potenciais plantas transg??nicas geradas, derivadas de sementes que tiveram o bot??o floral injetado com um vetor de express??o bin??rio, portador do gene cry1Ia12, foram inicialmente selecionadas com o antibi??tico canamicina. Plantas selecionadas foram caracterizadas por PCR, Southern blot, Western blot, e ensaio de ELISA, visando confirmar a transforma????o gen??tica. Os dados de Western blot e de ELISA mostraram uma express??o vari??vel da prote??na entre as plantas transg??nicas, com concentra????es variando de 1,?? ??g g-1 a ??,??6 ??g g-1. Ensaios biol??gicos com o inseto alvo utilizando plantas T1 revelaram os efeitos entomot??xicos da toxina Cry1Ia12 em Spodoptera frugiperda, evidenciado por uma diminui????o no desenvolvimento de insetos, em compara????o com as plantas controle n??o transformadas. Foi observado um efeito entomot??xico em Anthonomus grandis, demonstrado pela diminui????o no n??mero de adultos emergentes. No Cap??tulo 3, a t??cnica de transforma????o via agrol??stica foi utilizada para transformar uma cultivar de algod??o Coker 310 visando avaliar essa t??cnica. As plantas potencialmente transg??nicas geradas, derivadas dos embri??es transformados com o vetor portando os genes cry8Ka5 e ??AI-C3 foram selecionados in vitro e, posteriormente, aclimatizados em casa de vegeta????o. Estas plantas foram caracterizadas por PCR e ELISA para confirmar a transforma????o gen??tica. Sementes das plantas positivas foram semeadas para an??lise das plantas T1. A amplifica????o do gene cry8Ka5 foi observada e os resultados de ELISA mostraram uma express??o vari??vel da prote??na entre as plantas transg??nicas. Os estudos aqui apresentados demonstraram a efici??ncia na gera????o de plantas de algod??o GM, utilizando abordagens biotecnol??gicas alternativas e eficientes para controle de lepid??pteros e cole??pteros.

Characterizing the regime of Capital as the inconsistency of the present world, the communist hypothesis defended by Badiou states that the failures experienced in the attempts to construct a new world, a project of emancipation, should serve to assess the reasons of this failure, and never lead to relinquishment of further attempts. In the face of the failure in the attempt of making real a true idea, trying again is a feature of Badiou?s thinking and action. This thesis also analyzes the evolution of Badiou?s political thought and the nature of this evolution, still in course. It is also demonstrated that Badiou was affected by political processes and events of the class struggle in his militant period of life, the changes in the=o9?ituation and the effects of these changes in his formulations: the changes in his communist project. At the same time, it is evidenced the continuity in his thought, pointing out the most detachable indications of Badiou's fidelity to the communist idea, as well as to Marxism as a fundamental reference of his thought, of his general coordinates of political thinking and action. The central thesis is his loyalty to this idea. The thesis concludes with a case study, using the philosophical categories of the transformation theory formulated by Alain Badiou. This case study is the evaluation of the characteristics and meaning of the popular and youthful uprising experienced by Brazil in June 2013, analyzing whether this social and political process was what Badiou defined as the "event" or whether it was a normal fact, one more modification, trying to visualize its possible features and the subjects involved in its effects. It is also shown that June 2013 represented and continues to represent a political process which produces truths and, in this sense, has a close relationship with philosophy. / O tema desta tese ? a reivindica??o de Alain Badiou da ideia comunista como princ?pio da pol?tica, sua identifica??o do comunismo como o nome moderno do conceito de justi?a em Plat?o. Caracterizando o regime do Capital como a inconsist?ncia do mundo atual, a hip?tese comunista defendida por Badiou afirma que os fracassos experimentados nas tentativas de constru??o de um novo mundo, de um projeto de emancipa??o, devem servir para que se fa?am balan?os das raz?es deste fracasso, mas jamais devem levar a abandonar o empenho em novas tentativas. Diante do fracasso da implementa??o de uma ideia verdadeira, tentar de novo ? uma marca do seu pensamento e a??o. Nesta tese analisa-se a evolu??o do seu pensamento pol?tico e a natureza desta evolu??o ainda em curso; ainda, v?-se como, ao longo de sua trajet?ria, Badiou foi afetado por processos pol?ticos e acontecimentos da luta de classes em seu per?odo de vida militante, as mudan?as no estado da situa??o e os efeitos destas mudan?as nas suas formula??es: as mudan?as no interior da continuidade de seu projeto comunista. Ao marcar o fio de continuidade em sua elabora??o, apontamos as indica??es mais destac?veis da fidelidade de Badiou ? ideia comunista, bem como ao marxismo enquanto refer?ncia fundamental de seu pensamento, de suas coordenadas gerais de localiza??o pol?tica. A tese central ? sua fidelidade a esta ideia. A tese ser? conclu?da com um estudo de caso, utilizando as categorias filos?ficas da teoria da transforma??o formulada por Alain Badiou. Trata-se da avalia??o das caracter?sticas e do significado do levante juvenil e popular vivido pelo Brasil em junho de 2013, analisando se este processo social e pol?tico constituiu-se no que Badiou definiu com o conceito de ?acontecimento? ou se foi um fato normal, uma modifica??o a mais, tratando de visualizar suas eventuais marcas e os sujeitos envolvidos em seus efeitos. Mostra-se, ainda, que junho de 2013 representou e continua representando um processo pol?tico produtor de verdades e que, neste sentido, tem uma rela??o estreita com a filosofia.

O debate teve in?cio em finais da d?cada de 1980, contudo, recentemente a desacelera??o da ind?stria ganhou for?a nas discuss?es do meio acad?mico. Entre as principais teses nesse debate est? a novo-desenvolvimentistas que acredita na desindustrializa??o precoce causada principalmente pela sobreaprecia??o cambial. Contudo, parte da heterodoxia acredita que a desacelera??o da ind?stria esteja mais relacionada com a taxa de investimento do que do c?mbio. N?o obstante, segundo a tese ortodoxa, a perda de competitividade devido ao custo elevado de produ??o pode ter causada a desindustrializa??o no Brasil. Por outro lado, parte da ortodoxia n?o acredita que o pa?s esteja se desindustrializando, mas est? ocorrendo uma converg?ncia da ind?stria brasileira ? m?dia mundial. Assim, na tentativa de lan?ar luz sobre esse debate, o presente estudo busca identificar as raz?es da desacelera??o da ind?stria brasileira, enfatizando aspectos pouco explorados na literatura, e tentar definir se o pa?s padece ou n?o de um processo de desindustrializa??o. Ao analisar diversos indicadores, sobretudo, em n?vel de quantum, encontramos fortes ind?cios de que a desacelera??o da ind?stria brasileira pode ser caracterizada como uma desindustrializa??o, por?m ainda insuficiente para qualificar como precoce, dada a perda de participa??o da produ??o f?sica na produ??o total e o aumento da participa??o dos bens prim?rios na pauta de exporta??o / This study aims to contribute with evidence to reinforce or not the thesis of a possible deindustrialization of the Brazilian economy, with emphasis on period after 1995. The debate began in the late 80s, however, recently the industry deceleration gained strength in discussions academic. Between the main theses in this debate is the new-development that believes in precocious deindustrialization caused primarily by overvaluation exchange rate. However, part of heterodoxy believes the industry downturn is more related to the rate of investment than the exchange rate. Nevertheless, according to the orthodox thesis the loss of competitiveness due to the high cost of production may have caused the de-industrialization in Brazil. On the other hand, part of Orthodoxy does not believe that the country is deindustrializing it, but is occurring convergence of Brazilian industry the world average. Thus, in an attempt to shed light on this debate, this study intends to identify the reasons for the deceleration of the Brazilian industry, emphasizing aspects underexplored in the literature and define whether or not the country suffers a process of deindustrialization. When analyzing various indicators, especially the quantum level we find strong indications that the deceleration of the Brazilian industry can be characterized as a deindustrialization, though still insufficient to qualify as precocious, given the loss of share in physical production in total output and the share of primary goods in the export basket

S?o apresentados conceitos e diferentes vis?es da Educa??o Social, da Pedagogia Social e do Educador que atua no Programa Educa??o para o Trabalho e em Programas e projetos socioeducacionais. Buscou-se aprofundar tais conceitos em autores como Luzuriaga (1960) e Silva (2009) que abordam diferentes momentos da Pedagogia Social. A pesquisa tem por objetivo identificar as contribui??es do Educador para a forma??o e transforma??o da vida de jovens que participam do Programa Educa??o para o Trabalho. A quest?o que norteia o presente estudo assim se configura: Pode a Educa??o Social, no caso do Programa Educa??o Para o Trabalho, configurar-se em ambiente complementar ao ensino escolar, contribuindo para o desenvolvimento pessoal e profissional de jovens com interesse pelo mercado de trabalho? A metodologia utilizada foi a da pesquisa qualitativa. Foram aplicados 136 question?rios e realizadas 17 entrevistas com alunos, educadores e coordenadores do programa, visando conhecer as percep??es dos entrevistados a respeito do Programa pesquisado e das formas diferenciadas de educar que valorizam as experi?ncias e realidades individuais dos alunos. Constatou-se que o Programa atinge seu objetivo de contribuir para o desenvolvimento de jovens, como evidenciado nas entrevistas realizadas. Observou-se que o Programa proporcionou mudan?as na vida dos jovens e nas fam?lias destes jovens. Percebeu-se que o apoio e est?mulo da fam?lia para que os jovens permanecessem no Programa, representou fator determinante para os resultados alcan?ados. Os educadores foram un?nimes em afirmar que nutrem grandes expectativas com rela??o ao futuro dos jovens e acreditam, que de alguma forma, podem contribuir para proporcionar mudan?as significativas nas vidas destes jovens, n?o s? no ambiente profissional, mas tamb?m no pessoal. Espera-se que a pesquisa possa oferecer subs?dios que permitam aos educadores oportunidades de reflex?o sobre suas pr?ticas e sobre poss?veis mudan?as que possam ocorrer na vida dos jovens em diferentes contextos sociais.

A NiTi wire with 2.5 mm in diameter, received in the work hardened state, was submitted to annealing heat treatments at 450 ?C and 500 ?C in order to verify the calorimetric and microstructural changes. The microstructure in the work hardened condition and after the annealing heat treatments was analyzed, which showed a coarsening of the martensite plates for higher temperatures and longer heat treatment times. The determination of the transition temperatures (As, Af, Ms, Mf) and the change in the transformation temperatures between the as received worked hardened and annealed material, were determined. Microhardness measurements did not reveal any significant influence of the annealing or subzero heat treatments on the mechanical behavior of the alloy.

Foi utilizado o modelo de transforma??o da chuva em vaz?o, idealizado por RIGHETTO (2014), e, tamb?m, desenvolvido um modelo unidimensional que permite simular o processo de percola??o em condi??o de solo insaturado acoplado ao balan?o h?drico da LDI. Foi realizada a simula??o cont?nua ao longo de um per?odo de dezoito meses, com intervalos de tempo de um minuto. A BEM foi discretizada em quadras e trechos de rua e o perfil do solo em c?lulas verticais de 2 cm para um profundidade total de 30 m. Os hidrogramas gerados foram transformados em volumes afluentes ? lagoa. Na lagoa foi realizado o balan?o h?drico nesses intervalos de tempo, considerando-se a infiltra??o e percola??o de ?gua no perfil do solo. Como resultado, obteve-se a avalia??o da LDI no processo de armazenamento de ?gua, assim como a infiltra??o, redistribui??o de ?gua no solo e a recarga ao aqu?fero fre?tico, possibilitando simular a sequ?ncia temporal de distribui??o. Com as simula??es realizadas, verificou-se o desempenho da LDI na absor??o de cheias e sua contribui??o no processo de recarga local do aqu?fero (Aqu?fero Dunas / Barreiras). / A type of macro drainage solution widely used in urban areas with predomi-nance of closed catchments (basins without outlet) is the implementation of detention and infiltration reservoirs (DIR). This type of solution has the main function of storing surface runoff and to promote soil infiltration and, consequently, aquifer recharge. The practice is to avoid floods in the drainage basin low-lying areas. The catchment waterproofing reduces the distributed groundwater recharge in urban areas, as is the case of Natal city, RN. However, the advantage of DIR is to concentrate the runoff and to promote aquifer recharge to an amount that can surpass the distributed natu-ral recharge. In this paper, we proposed studying a small urban drainage catchment, named Experimental Mirassol Watershed (EMW) in Natal, RN, whose outlet is a DIR. The rainfall-runoff transformation processes, water accumulation in DIR and the pro-cess of infiltration and percolation in the soil profile until the free aquifer were mod-eled and, from rainfall event observations, water levels in DIR and free aquifer water level measurements, and also, parameter values determination, it is was enabled to calibrate and modeling these combined processes. The mathematical modeling was carried out from two numerical models. We used the rainfall-runoff model developed by RIGHETTO (2014), and besides, we developed a one-dimensional model to simu-late the soil infiltration, percolation, redistribution soil water and groundwater in a combined system to the reservoir water balance. Continuous simulation was run over a period of eighteen months in time intervals of one minute. The drainage basin was discretized in blocks units as well as street reaches and the soil profile in vertical cells of 2 cm deep to a total depth of 30 m. The generated hydrographs were transformed into inlet volumes to the DIR and then, it was carried out water balance in these time intervals, considering infiltration and percolation of water in the soil profile. As a re-sult, we get to evaluate the storage water process in DIR as well as the infiltration of water, redistribution into the soil and the groundwater aquifer recharge, in continuous temporal simulation. We found that the DIR has good performance to storage excess water drainage and to contribute to the local aquifer recharge process (Aquifer Dunas / Barreiras).

In this case, it is necessary to use biotechnology and its tools applied to non-conventional genetic improvement to develop new varieties that have resistance to their different types of pathogens.This work was carried out with the objective of adapting the technique of obtaining embryogeniccallus of banana by means of the Scalp method in cultivars Brazilian Ma?? and Pacovan, adjusting the processes of induction of meristematic structures and multiplication of shoots and induce increased genetic variability by in vitro mutagenesis using the chemical agent ethylmethanesulfonate and, of the genetic transformation by the bombardment of microparticles. Was evaluated the callus formation, the effect of mutagenic in the in vitro cultivation of shoots and the effects of genetic transformation on shoot resistance in selection medium containing the herbicide Imazapyr. The results showed that the merystematic structures obtained have the capacity to origin callus with only one month of cultivation, and both cultivars developed friable callus with average values above 90%.The efficiency of this method was evidenced by the high capacity of induction of friable callus in the two evaluated cultivars but also by the rapidity in the process of obtaining calluses, being the first study of adaptation of the methodology for Brazilian banana cultivars.On the other hand, the evaluation of the mutation induction allowed to conclude that the survival and the capacity of bud formation decreased as a function of the increase of the concentration and the immersion time in the ethylmethanesulfonate.The surviving plants underwent a sorting with the fusaric acid selective agent in which it was possible to regenerate in vitro plants of the cultivars submitted to treatment with the mutagen and to select possible mutants with fusaric acid resistance for cultivarsMa?? and Pacovan.And the genetic transformation method proved efficient in the regeneration of shoots resulting in high values of survival and multiplication, where possible transgenic plants of banana cv. Ma?? were obtained after selection of resistance to the herbicide.Therefore, it is concluded that all the material produced, both in the mutagenic phase and in the genetic transformation, presents a greater genetic variability potentially applicable to the banana improvement. / A banana (Musa spp.) ? considerada um dos mais importantes frutos no com?rcio mundial em virtude seu potencial nutritivo e econ?mico. Mas, apesar de existir um grande n?mero de variedades no mercado, a bananeira ainda ? acometida por muitas doen?as. A aplica??o do m?todo de cruzamentos nesta esp?cie ? muito dif?cil, pois a maioria das variedades cultivadas ? triploide apresentando baixa fertilidade. Nesse caso, faz-se necess?rio o uso da biotecnologia e de suas ferramentas aplicadas ao melhoramento gen?tico n?o convencional para desenvolver novas variedades que tenham resist?ncia aos seus diferentes tipos de pat?genos. Este trabalho foi realizado com os objetivos de adaptar a t?cnica de obten??o de calos embriog?nicos de bananeira por meio do m?todo Scalp nas cvs. Ma?? e Pacovan, ajustando os processos de indu??o de estruturas polimeristem?ticas ede multiplica??o de brotos e induzir o aumento da variabilidade gen?tica por meio da mutag?nese in vitro com o uso do agente qu?mico etilmetanosulfonato e, da transforma??o gen?tica pelo bombardeamento de micropart?culas.Foram avaliados os calos formados, o efeito do mutag?nico no cultivo in vitro de brotos e, os efeitos da transforma??o gen?tica quanto ? resist?ncia dos brotos em meio de sele??o contendo o herbicida Imazapyr. Os resultados mostraram que as estruturas polimeristem?ticas obtidas t?m capacidade de originar calos com apenas um m?s de cultivo e, ambas as cultivares desenvolveram calos fri?veis com rendimentos m?dios acima de 90%. A efici?ncia desse m?todo foi comprovada pela alta capacidade de indu??o de calos fri?veis nas duas cultivares avaliadas, como tamb?m pela rapidez no processo de obten??o de calos, sendo este o primeiro estudo de adapta??o da metodologia para as cultivares Ma?? e Pacovan. Por outro lado, a avalia??o da indu??o de muta??o permitiu concluir que a sobreviv?ncia e a capacidade de forma??o de brotos diminu?ram em fun??o do aumento da concentra??o e do tempo de imers?o no etilmetanosulfonato. As plantas sobreviventes passaram por uma triagem com o agente seletivo ?cido fus?rico na qual, foi poss?vel regenerar plantas in vitro das cultivares submetidas ao tratamento com o mutag?nico e selecionar poss?veis mutantes com resist?ncia ao ?cido fus?rico para as cvs. Ma?? e Pacovan. O m?todo da transforma??o gen?tica mostrou-se eficiente na regenera??o dos brotos resultando em altos valores de sobreviv?ncia e multiplica??o, onde poss?veis plantas transg?nicas de bananeira cv. Ma?? foram obtidas, ap?s a sele??o de resist?ncia ao herbicida. Portanto, conclui-se que todo material produzido, tanto na fase mutag?nica quanto na transforma??o gen?tica, apresenta uma maior variabilidade gen?tica potencialmente aplic?vel ao melhoramento da bananeira.
