Engraçadinha : passagens e cortes / Nelson Rodrigues na televisão
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoAsfalto Selvagem I e II - Engraçadinha seus amores e seus pecados foi escrito por Nelson Rodrigues, originalmente, sob a forma de folhetim, diariamente publicado no jornal Ultima Hora (1959-60), e seguindo o caminho de seus folhetins anteriores recebeu uma impressão posterior (1961) em forma de livro, "transformando-se" em romance. Em 1995, novamente, Asfalto Selvagem... migra para outro veículo da indústria cultural indo parar num seriado de televisão. Este trabalho propõe retraçar as pontes entre o folhetim como forma de literatura industrializada e a televisão como veículo da indústria cultural e como bem simbólico (na cultura brasileira), a fim de localizar Asfalto Selvagem: Engraçadinha seus amores e seus pecados em sua passagem do jornal à televisão em alguns aspectos implicados nesse processo. Em primeiro lugar, na obra de Nelson Rodrigues, Engraçadinha destaca-se em sua travessia social de gêneros e como romance-folhetim. Em segundo lugar, há uma re-montagem histórica da teledramaturgia como pano de fundo propiciador de uma exposição do folhetim de Nelson Rodrigues. Em terceiro lugar, a passagem, propriamente dita, do folhetim à imagem, se por um lado reforça o caráter conservador da TV, por outro, atualiza a transgressividade erótica presente no texto rodrigueano, já como uma adaptação ao século XX do folhetim do século XIX
A polinização da pereira europeia (pyrus communis L. cv. Rocha) no sul do Brasil
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Programa de Pós-Graduação em Recursos Genéticos Vegetais, Florianópolis, 2014No Brasil, a produção de pera é insuficiente para atender a demanda interna, gerando uma crescente necessidade de importação de frutas que podem ser produzidas nas regiões mais frias. Por isso, a pera é a fruta fresca importada em maior quantidade pelo Brasil. Por ser alógama devido à incompatibilidade gametofítica, a maioria das cultivares europeias de pereiras não produzem frutos com sementes sem a presença de insetos polinizadores. Neste contexto, foram realizados ensaios buscando elucidar os aspectos da biologia reprodutiva da pereira portuguesa (Pyrus communis L. cv. Rocha) e suas cultivares polinizadoras, assim como avaliar a qualidade das colmeias destinadas à polinização. Os resultados mostraram que a fenologia das cvs. Rocha e suas polinizadoras diferiu entre elas e entre os anos, podendo afetar significativamente a polinização. A data aproximada da plena floração das cultivares estudadas foi similar em 2012 (? 17//09), porém, diferiu em 2013. Foi observado que a cv. Rocha polinizada com pólen de cultivares compatíveis apresentou elevada frutificação efetiva, chegando a atingir até 67,8% de frutificação efetiva sem a aplicação exógena de giberelina. Além disso, nestes frutos observou-se maior número de sementes (>5 sementes.fruto-1), o que acarretou frutos com melhores índices de qualidade comparativamente com outros tratamentos de polinização. A autopolinização promoveu a formação de frutos (10,9% de frutificação efetiva em 2012 e 1,66% em 2013), mas em quantidade e qualidade inferiores aos frutos oriundos de polinização cruzada. A partenocarpia natural foi observada na cv. Rocha, mas esta incapaz de sustentar produções comercialmente viáveis (4,16% de frutificação efetiva). A aplicação exógena de ácido giberélico mostrou ser uma opção para o aumento da frutificação efetiva através do estímulo da formação de frutos partenocárpicos, contudo foi observada uma variação na sua eficiência entre os anos (frutificação efetiva de 74,1% em 2012, reduzindo para 30,0% no ano seguinte) e a tendência da redução da qualidade dos frutos formados, os quais eram menores e mais alongados do que os frutos com sementes. A produção de néctar variou entre cultivares e entre os anos, mas sendo sempre considerados volumes pequenos (Abstract: In Brazil, the pear production is insufficient to supply the domestic demand, creating a growing market for imported fruits that can be produced in south Brazil. Due to this, Brazil's fresh pear imports grow every year. Since pears are alogamous due to gametophytic incompatibility, most European pear cultivars do not produce fruit with seeds without the presence of pollinating insects. In this context, experiments were conducted to elucidate the aspects of the reproductive biology of the Portuguese pear (Pyrus communis L. cv. Rocha) and their pollinating cultivars, as well as the quality of the hives used for orchard pollination. The results show that the phenology of cvs. Rocha and their pollinators differs between them and years, which may significantly affect pollination. The approximate date of full bloom of the cultivars was similar in 2012 (~=17/09) while differ in 2013. We observed that cv. Rocha pollinated with pollen from compatible cultivars showed a high fruit set, reaching up to 67,8% of fruit set without exogenous gibberellin application. Moreover, in these fruits was observed a greater number of seeds (> 5 seeds.fruit-1), which resulted in higher quality fruits (scores compared with other pollination treatments). Self-pollination produced some fruits (10,9% of fruit set in 2012 and 1,66% in 2013), but in lower quantity and quality when compared with cross-pollination. Natural parthenocarpy was observed in cv. Rocha, but it was unable to sustain commercially viable yields (4,16% of fruit set). The exogenous gibberellic acid application was an option for increasing fruit set by stimulating the formation of parthenocarpic fruits, however we observed a variation of it's efficiency between years (fruit set of 74,1% in 2012, decreasing to 30,0% in 2013) and showed a trend of reduced quality of formed fruits, which were smaller and more elongated than the fruit with seeds produced by cross-pollination. Nectar production varied among cultivars and years, but always being considered small volumes (<3µL) and whith low sugar content (<20ºBrix), which resulted in low attractiveness of pollinators (<1 bee.tree-1.minute-1). In the surrounding area of the orchard we observed strong competition with Mimosa scabrella and Piptocarpha angustifolia wich bear more and richer nectar. We observed poor natural pollination due to the non-pollen deposition on the stigmas of 'Rocha' after a legitimate flower visit by Apis mellifera, possibly due to lack of pollinating plants and low density of quality beehives in the orchard. The hives used for pollination showed a variation in their population between years, wich can be observed in the significant reduction in the number of combs covered with larvae and honey reserves from 2012 to 2013, resulting in lower activity of foraging bees in the period of maximum flight activity (100,8 foraging bees entering in the hive.minute-1 in 2012 and 59,3 foraging bees entering in the hive.minute-1 in 2013). We also observed the presence of Varroa destructor (infestation of 1.89 and 1.45% in 2012 and 2013, respectively) and Nosema ceranae (712.000 spores.bee-1 in 2012)
Invenção em trânsito/transe: Glauber Rocha, Hélio Oiticica e Tropicália
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2013.Terra em Transe, Tropicália. É já conhecida a relação criadora, propulsora entre o filme e a canção. Em retrospectivas tropicalistas, é oficial esta associação: o longa-metragem de Glauber Rocha ? a música que desencadeou o tropicalismo ? a instalação de Hélio Oiticica - a montagem do texto de Oswald de Andrade, O Rei da Vela, pelo teatro Oficina. Pretendemos aqui, além desse reconhecimento, compreender de que forma a obra cinematográfica de Glauber Rocha e a cena, o momento, o comportamento tropicalista, em alguns de seus aspectos, abrem pontos de aproximação e distanciamento, (des)encontram-se. Propomos, para isso, algumas leituras que partem primeiramente da análise de Terra em Transe, filme de 1967; seu impacto, fissura aberta em contexto, cenário cultural/estético/político, e dentro do próprio cinema do diretor; sua relação com os desdobramentos do conceito Tropicália, de Hélio Oiticica, vinculados às ideias políticas em torno da construção/arquitetura de Brasília, que desembocam na letra da composição de Caetano Veloso. Em um segundo momento do trabalho, é a análise mais detida de Deus e o Diabo na Terra do Sol (longa-metragem de Glauber, de 1964) que abre uma série de diálogos - em transe pela terra - com os processos de criação-invenção de Hélio Oiticica: os Penetráveis (marcadamente os de sua Tropicália); os Bólides (a proposição de obra aberta no Contra-Bólide N°1 Devolver a terra à Terra, e o "momento ético" no Bólide B33 Caixa 18 Homenagem a Cara de Cavalo); o Parangolé. É este que, através da dança, leva/conduz ao corpo, como elemento de desestruturação da linguagem cinematográfica, da música popular brasileira, e dos parâmetros estabelecidos do que seja arte. Nesses exercícios de aproximação e distanciamento, muitas vezes, o que entendemos por "teoria" sobressai dos escritos, críticas, pensamentos dos próprios criadores, colocados em (des)espelhamento no processo de apagamento das fronteiras entre vivência do cotidiano/criação artística, vida/obra.<br

Nelson Rodrigues e sua cena: teatro da dupla tensão, cinema da síntese
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação em LiteraturaEsta tese busca uma leitura possível das razões do fracasso de grande parte das adaptações da dramaturgia de Nelson Rodrigues para o cinema. Sua primeira investida percorre o teatro rodrigueano, elaborando o conceito de dupla tensão como marca do autor. A primeira tensão, articulada ainda nos domínios temáticos, responderia pelo embate firmado entre o Brasil anterior à gripe-espanhola e os "novos tempos", dominados por uma modernidade produtora de tripla decadência, como pensa Eric Hobsbawm. A segunda tensão, insinuada nos domínios estéticos, promoveria certo afastamento do conceito de drama puro, segundo teoria de Peter Szondi, ao se deixar contaminar por gêneros diversos, posicionando-se entre o melodramático e o trágico. Neste contexto, Toda nudez será castigada, peça de 1965, seria o ponto mais alto desta trajetória. Tal conformação, perseguida em todo o teatro do autor, não parece ter encontrado eco nas releituras do cinema, quase todas reducionistas do universo tensional. A única experiência de exceção parece acontecer na versão de Arnaldo Jabor justamente para Toda nudez será castigada, filme de 1973 que transforma em ritmo próprio as tensões típicas da dramaturgia rodrigueana, movimento contrário às outras versões, que tentaram corrigi-las com sínteses nas mais variadas proposições
The Effective Lorentzian And Teleparallel Spacetimes Generated By A Free Electromagnetic Field
No full textIn this paper we show that a free electromagnetic field living in Minkowski spacetime generates an effective Weitzenböck or an effective Lorentzian spacetime whose properties are determined in details. These results are possible because using the Clifford bundle formalism we found a noticeable result that the energy-momentum densities of a free electromagnetic field are sources of the Hodge duals of exact 2-form fields which satisfy Maxwell like equations. © 2008 Polish Scientific Publishers PWN, Warszawa.6216989Hestenes, D., (1966) Space Time Algebra, , Gordon and Breach, New YorkFernández, V.V., Moya, A.M., Rodrigues Jr., W.A., Extensors (2001) Adv.

The Maxwell And Navier-stokes Equations That Follow From Einstein Equation In A Spacetime Containing A Killing Vector Field
No full textConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)In this paper we are concerned to reveal that any spacetime structure 〈M, g, D, τg, ↑〉, which is a model of a gravitational field in General Relativity generated by an energy-momentum tensor T - and which contains at least one nontrivial Killing vector field A - is such that the 2-form field F = dA (where A = g(A,)) satisfies a Maxwell like equation - with a well determined current that contains a term of the superconducting type- which follows directly from Einstein equation. Moreover, we show that the resulting Maxwell like equations, under an additional condition imposed to the Killing vector field, may be written as a Navier-Stokes like equation as well. As a result, we have a set consisting of Einstein, Maxwell and Navier-Stokes equations, that follows sequentially from the first one under precise mathematical conditions and once some identifications about field variables are evinced, as explained in details throughout the text. We compare and emulate our results with others on the same subject appearing in the literature. In Appendix A we fix our notation and recall some necessary material concerning the theory of differential forms, Lie derivatives and the Clifford bundle formalism used in this paper. Moreover, we comment in Appendix B on some analogies (and main differences) between our results to the ones obtained long ago by Bergmann and Kommar which are reviewed and briefly criticized. © 2012 American Institute of Physics.1483277295Cons.

The species name is derived from the coloration of the tunic in resemblance to that of the common beet, Beta vulgaris. Description. Living specimens present dark red or wine coloration often resembling the coloration of a beet (Fig. 1A, B, C), sometimes with a tinge of yellow towards the base of the animal. It loses some coloration after a long fixation. The tunic is hard, 2–3 mm thick, with divisions forming small patches on the surface (Fig. 1D), and frequently, but not always, masked by epibionts and debris. The animal is elongated and attaches along the ventral margin to mangrove prop roots, to exposed coral skeleton or rocky walls in shallow waters (less than 5 m in Panama but to 15 m in Brazil), in a vertical position, with the oral siphon apical and the atrial siphon short and posterior. The siphons are surrounded by tubercles (Fig. 1C). The holotype is 11 cm in total length, but individuals from 7 to 8 cm long are more common and this was the maximum size found in Brazil. The color of the inner tunic lining depends on the duration of fixation. Freshly fixed specimens present red or wine coloration; however, over the course of time, the tunic shows a gradient from red to white. With the tunic removed, the holotype is 8.5 cm at the longest length; the oral siphon is 2 cm long and the atrial siphon is 1.5 cm long. Body wall musculature is robust. Thick longitudinal bands composed of many muscle fibers radiate from the siphons and terminate at the level of the gonadal and intestinal region, where those bands divide into numerous thinner fibers leaving this area more transparent (Fig. 2A, B, D). The number of muscle bands varies; the right side of the body often has 21–24 bands, and the left side 23–25. Circular musculature around the siphons is also very strong and forms wide bands at the base of both siphons covering the longitudinal bands. The siphons present a variation of red and yellow in recently preserved animals. Internally, the siphons have a velum, but spinules are absent. Oral tentacles are uncolored, laterally flattened, and triangular with a very wide base. First order ramifications are arranged in a line along the posterior margin, and second order ramifications are minute (Fig. 3A). Tentacles are in three different sizes, the largest circa 7 mm long, and the smallest usually attached along a line at a more posterior level. The number of tentacles ranges from 26 to 50 in the species; 18 large and medium tentacles and 30 smaller and displaced posteriorly in the holotype. A small distance separates the tentacles and the prepharyngeal groove, and this narrow region is smooth. The prepharyngeal groove is formed by two equal size lamellae that establish a very deep V where the dorsal tubercle is situated. The dorsal tubercle aperture is U or V-shaped, very narrow, lying deep in the V (Fig. 3B). The dorsal lamina starts after the insertion of the first right dorsal branchial fold and extends to the esophageal opening with 60–125 long languets, ~ 125 in the holotype. The length of the languets increases posteriorly (Fig. 3F). The pharynx is uncolored and transparent with six high folds per side (Figs. 2C, 3D). Fold overlap occurs on both sides, however, the folds on the right side of the holotype show more overlap than the left side. The holotype (11 cm) has 440 total longitudinal vessels and the longitudinal vessel formula is (from right to left): E 10 (17) 11 (30) 4 (32) 4 (36) 6 (33) 5 (25) 4 DL 3 (35) 10 (30) 7 (33) 8 (32) 9 (35) 10 (16) 5 E Other samples: Panama: E 5 (19) 4 (24) 7 (26) 5 (27) 4 (24) 5 (24) 4 DL 2 (21) 4 (22) 7 (26) 6 (24) 6 (23) 6 (24) 5 E MZUSP 557 (4 cm): E 6 (12) 2 (15) 4 (15) 4 (15) 4 (14) 2 (12) 2 DL 2 (12) 2 (16) 2 (16) 5 (14) 4 (12) 3 (11) 3 E DZUP PYU54 (4.5 cm): E 7 (17) 3 (22) 2 (21) 2 (22) 6 (14) 5 (14) 3 DL 2 (22) 3 (19) 2 (25) 1 (24) 2 (19) 1 (17) 8 E DZUP PYU75 (3.48 cm): E 6 (15) 3(17) 3 (20) 3 (19) 3 (13) 3 (17) 2 DL 2 (16) 1 (15) 2 (19) 2 (18) 3 (17) 2 (12) 4 E MZUSP 0 0 0 41 (3.5 cm): E 8 (10) 4 (16) 4 (16) 3 (16) 3 (16) 3 (15) DL 2 (17) 3 (12) 4 (16) 4 (19) 4 (13) 3 (10) E There are frequently five or six stigmata per mesh, both between and on folds, but some samples from Brazil had four. Parastigmatic vessels are present; however, not in every mesh and can be incomplete (Fig. 3E). Posteriorly languets extend around the right side of the esophageal opening; there are 45 of those languets in the holotype. The pharynx is attached to the body wall by numerous thick vessels. Significantly smaller ones attach the pharynx to the gonadal and intestinal regions. The intestine is isodiametric, and the primary intestinal loop extends anteriorly, sometimes two thirds to half of the distance to the peripharyngeal groove. The loop is narrow with parallel ascending and descending portions along the ventral margin (Fig. 2D). The secondary loop is very small and ends in a smooth anus (Fig. 3G). Sometimes, a slight constriction at the pre-anal region could be noted. Endocarps line the ascending and descending intestine, both inside and outside the loop. The ones ventral to the ascending intestine are laminar, very thin and circular, while those lining the descending intestine are fleshy, irregular and more numerous (Fig. 2D). Endocarps are also present attached to the body wall. A large digestive gland, 2 cm long in the holotype, shows two connections with the stomach; there are additional small portions on the esophagus (Fig. 3H). The atrial velum is red in freshly preserved animals, wide and waving, and without thread-like projections (Fig. 2D). The left gonad occupies the entire space of the first gut loop and contains 34 irregularly shaped lobes in the holotype, but the number of gonad lobes ranges from 34 to 62. They intermittently present fleshy endocarps on the top of the lobes. The right gonad is ventral and takes the form of a backward J. The right gonad extends up to the same position that the intestinal loop does on the left side (Fig. 2D), with 62 irregular shaped gonad lobes placed tightly together in the holotype, ranging from 38 to 82 lobes in other samples. The right gonad also has small endocarps on the tops of some lobes. Large and complex fleshy endocarps attached to the body wall line the anterior and dorsal sides of the right gonad. Gonoducts are short on both sides and the oviduct is lobed (Fig. 3G). Remarks. This species can be confused with Pyura vannamei because of the similar color of living animals and the elongated body with a posterior atrial siphon. The distribution of P. vannamei is restricted to the Caribbean region and in the field, it has never been found on mangrove roots. It generally lies horizontally on the ventral side with both siphons up while P. beta generally lies vertically on coral heads or mangrove roots, with the oral siphon up and the atrial siphon posterior and lateral. Pyura beta living color is usually redder and P. vannamei is usually more purple, but both tend to red after preservation in formalin. The two species also differ in that P. beta has colored muscles when fresh and an isodiametric intestine with small secondary loop and smooth anus, whereas P. vannamei has white muscles in fresh samples and an enlarged hind pouch in the second loop, and lobed anus (Monniot 1994). Pyura beta was first collected from the Brazilian coast in 1961 during an R.V. Calypso expedition and deposited on MZUSP as P. vittata by Sérgio A. Rodrigues (Rodrigues 1966). In 1997 one of us (R.M. Rocha) collected two individuals at Cabras Island, São Sebastião, SP, but also identified them as P. vittata (DZUP PYU- 22). Since then, many other individuals from the southwestern Atlantic have been collected, mainly from some coastal islands. Brazilian specimens are light reddish to yellow, but all other features are similar with Caribbean ones (Fig. 4). They have been identified as P. vittata but both species are different in many aspects: P. vittata is more or less globular in shape, the tunic is thin and white internally, the siphons are closer when compared to P. beta with long (up to 0.32 mm) and iridescent s pinules noticeable even on the outside of the siphons (Monniot 2018), and the body musculature is less developed. Also, in P. vittata, the right gonad is in a more median portion of the body and it is more dorsally curved (Monniot 1983). In a short visit to the Smithsonian Collection in Washington, DC we had the opportunity to see some samples and it is possible that the specimens USNM 21805 and USNM 1090900 collected in Pelican Bay, Belize and identified by I. Goodbody as Pyura lignosa may be P. beta. External appearance looks exactly the same but there was not enough time for a complete dissection. Goodbody (2000) mentions animals exceeding 15 cm in length. If this identification is confirmed the geographical distribution of the species is enlarged. Monniot (2016) recently reported P. vittata from French Guiana but the description given resembles P. beta, except for the smaller size and color of preserved animals. The animals do not have the enlarged posterior intestinal region and the author does not mention the presence of siphonal spines, both characteristics typical of P. vittata (see Monniot 1983).Published as part of Skinner, Luís Felipe, Rocha, Rosana M. & Counts, Bailey K., 2019, Pyura gangelion and Pyura beta sp. nov.

Glauber Rocha: de Xenofonte a Euclides da Cunha, de Euclides da Cunha a Xenofonte
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2012Esta tese sobre a produção cinematográfica de Glauber Rocha visa mostrar como o sertão euclidiano, reconhecido no trabalho do cineasta durante a década de 1960, retorna durante a década de 1970 por intermédio do historiador grego Xenofonte a partir do roteiro La nascita degli dei, escrito na Itália, durante o período de exílio, e publicado no mesmo ano de sua morte. O sertão como fio condutor, ao ser lido também na década de setenta, distanciado de seu poder de representação, permite, com Badiou e Deleuze, outra possibilidade de leitura, anabática e palimpséstica, que se estende pelo corpo da obra de Glauber.Abstract : This thesis on Glauber Rocha's cinematographic production has the objective to show in which ways the wilderness (sertão) in Euclides da Cunha's works acknowledged into the film-maker work during the 60's decade, returns in the 70's by the Greek historian Xenofonte with the script La nascita degli dei written in Italy during his exile, and published in the same year of his death. The wilderness (sertão) consider as a conductor image to the script, when read also in the 70's away from its representation power, allows other reading possibilities anabatic and palimsestic, for instance, via Badiu and Deleuze, which spreads itself throughout Glauber's work
