A ironia na peça O rei da velha, de Oswald de Andrade

Este trabalho tem como objetivo traçar um panorama artístico literário presente na produção do escritor modernista Oswald de Andrade, identificando a evolução estética ideológica do autor por meio do manifesto Pau-Brasil (1925) e o Antropófago (1928); de teses e artigos como “Meu Testamento” (1944) e “A crise da filosofia Messiânica” (1945); de entrevistas presentes no livro Telefonema, parte integrante da coleção: Obras Completas de Oswald de Andrade (Rio de janeiro, 1974); e de sua produção teatral. Toma como ponto de partida a antropofagia como um operador cultural, de modo que a característica mais marcante do escritor, a irreverência, é fomentada e trabalhada por meio da ironia, ferramenta de discurso que Oswald de Andrade utiliza com uma função social, uma arma revolucionária e política. Para tal, traçou-se uma linha entre a produção modernista e a produção teatral de Oswald e desse levantamento bibliográfico, a peça que mais chamou a atenção foi O rei da vela, primeira peça escrita na fase adulta, em 1933, e publicada em 1937 e que somente teve sua primeira encenação 30 anos depois, em 1967, pelo grupo de Teatro Oficina com a direção de José Celso Martinez Corrêa. O grupo realizou um levantamento literário e documental sobre o Oswald de Andrade, através de depoimentos dos atores que receberam a proposta de encenação (em 1934), aos Manifestos, até encontrar a Antropofagia oswaldiana, e dela se utilizarem para concretizar O rei da vela, retomando e usando a antropofagia, essencialmente, como um operador cultural

Oswald de Andrade e Tarsila do Amaral: poesia e pintura modernistas

The objective of the present text is to establish connections between literature and painting through the comparison between Oswald de Andrade’s poem “Longo da Linha” and Tarsila do Amaral’s painting “Palmeiras”, both belonging to the Brazilian Modernist movement Pau-Brasil. To emphasize also the step taken by the two artists, in Modernism, against the previous academicism, C. S. Peirce’s semiotics theory will be used as analytic basis to demonstrate, in Tarsila’s painting, a path towards planarity and stylization to produce quality effects, closer to the shape and the adventure of senses than to symbolization, whilst for Oswald, this same path leads to the presence of visualization as composition factor.

Antropofagia, dessacralização e devoração em Rilke Shake, de Angélica Freitas

This article investigates the presence of anthropophagy on Rilke shake, analyzing the opening poem “perfect teeth, listen to me,” by the concept of devouring. It discusses how the “Poesia Pau-Brasil” by Oswald de Andrade would be the milestone of a conception of poetry desacralized in Brazil in the twentieth century, retaken by marginal generation and kept alive by Angélica Freitas, with a increasingly accelerated consumption into society as a background.

Subdoses de glyphosate no desenvolvimento de espécies arbóreas nativas

Recovery of degraded areas aims to provide the degraded environment favorable conditions for restructuring in an environment that is unable to regenerate itself and planting of tree seedlings is one of the effective ways to extend this process. However, native tree species have slow growth rate which increases the seedlings production time as well as decreases their competitiveness with weeds in areas of forests deployment. The aim of this study was to evaluate the effects of glyphosate reduced rates application on Psidium cattleyanum (yellow guava), Citharexylum myrianthum (pau-viola) and Cedrela odorata (cedro) seedlings development by analyzing its morphophysiological parameters. The experiment was carried out in greenhouse conditions and the experimental units consisted of one plant were conducted in 2.5L plastic pots and arranged in a completely randomized design with six replications. Treatments consisted of glyphosate application at 0, 7.5, 15, 30 and 60 g ha(-1) using Scout (R) commercial formulation. Treatments application on these species seedlings was realized 120 days after seeds germination. Visual evaluations of plants phytotoxicity were realized at 7, 14 and 21 days after treatments application and plants survival, stomatal conductance, height, stem diameter and dry mass of shoots were evaluated 90 days after treatments application. Different doses of glyphosate did not cause plants phytotoxicity. Already, 30 and 60 g ha(-1) of glyphosate provided greater increases in height, stem diameter and dry mass of shoots for Citharexylum myrianthum and Psidium cattleyanum, respectively.

Índice de importância de diferentes espécies de plantas na atração de aves para uma área reflorestada em Piracicaba

A restauração de áreas degradadas pode beneficiar espécies típicas do ambiente original, com a expansão e criação de habitats, tornando-se uma ferramenta de extrema importância para a conservação. Frugívoros atraídos por plantas zoocóricas utilizadas em plantios não apenas podem dispersar sementes dessas plantas como também trazer sementes alóctones, promovendo a diversidade genética local. Assim, é fundamental entender as condições em que o processo de dispersão de sementes opera, a fim de subsidiar programas de recuperação ambiental. Este trabalho avaliou a importância das espécies: embaúba (Cecropia pachystachya), pitanga (Eugenia uniflora), figueira-do-brejo (Ficus insipida), aroeira-pimenteira (Schinus terebinthifolius), pau-pólvora (Trema micranta), fumo-bravo (Solanum mauritianum) na atração de aves frugívoras em uma Área de Preservação Permanente de 6,2 ha replantada em 2006 no município de Piracicaba, São Paulo. Apenas C. pachystachya, E. uniflora e F. insipida foram utilizadas no plantio, o que indica que as outras espécies foram introduzidas pela fauna. Observações focais foram realizadas em pelo menos dois indivíduos de cada espécie, totalizando dez horas de observação por espécie. Foram registradas 29 espécies de aves alimentandose dos frutos. Utilizando-se de uma adaptação da fórmula de Murray (2000) para o índice de importância na atração da avifauna, foram encontrados os valores de 0,086 para C. pachystachya, 0,031 para E. uniflora, 0,020 para F. insipida, 0,123 para S. terebinthifolius, 0,083 para S. mauritianum e 0,623 para T. micrantha. O grande valor observado para essa última em relação às outras pode ser justificado pelo grande número de espécies visitantes e de relações exclusivas, especialmente com aves que são predominantemente insetívoras ou granívoras. A importância de T. micrantha provavelmente se deve à alta concentração de lipídios em seu fruto. Os...

Participative site-specific agriculture analysis for smallholders

Site-specific agriculture has been adopted in a high-tech context using, for instance, in situ sensors, satellite images for remote sensing analysis, and some other technological devices. However, farmers and smallholders without the economic resources and required knowledge to use and to access the latest technology seem to find an impediment to precision agricultural practices. This article discusses the possibility of adopting precision agriculture (PA) principles for site-specific management but in a low technology context for such farmers. The proposed methodology to support PA combines low technology dependency and a participatory approach by involving smallholders, farmers and experts. The case studies demonstrate how the interplay of low technology and a participative approach may be suitable for smallholders for site-specific agriculture analysis.

MAPPING, ORGANIC MATTER MASS AND WATER VOLUME OF A PEATLAND IN SERRA DO ESPINHACO MERIDIONAL

Peatlands form in areas where net primary of organic matter production exceeds losses due to the decomposition, leaching or disturbance. Due to their chemical and physical characteristics, bogs can influence water dynamics because they can store large volumes of water in the rainy season and gradually release this water during the other months of the year. In Diamantina, Minas Gerais, Brazil, a peatland in the environmental protection area of Pau-de-Fruta ensures the water supply of 40,000 inhabitants. The hypothesis of this study is that the peat bogs in Pau-de-Fruta act as an environment for carbon storage and a regulator of water flow in the Corrego das Pedras basin. The objective of this study was to estimate the water volume and organic matter mass in this peatland and to study the influence of this environment on the water flow in the Corrego das Pedras basin. The peatland was mapped using 57 transects, at intervals of 100 m. Along all transects, the depth of the peat bog, the Universal Transverse Mercator (UTM) coordinates and altitude were recorded every 20 m and used to calculate the area and volume of the peatland. The water volume was estimated, using a method developed in this study, and the mass of organic matter based on samples from 106 profiles. The peatland covered 81.7 hectares (ha), and stored 497,767 m(3) of water, representing 83.7 % of the total volume of the peat bog. The total amount of organic matter (OM) was 45,148 t, corresponding to 552 t ha(-1) of OM. The peat bog occupies 11.9 % of the area covered by the Corrego das Pedras basin and stores 77.6 % of the annual water surplus, thus controlling the water flow in the basin and consequently regulating the water course.

Chemopreventive effect of Copaifera langsdorffii leaves hydroalcoholic extract on 1,2-dimethylhydrazine-induced DNA damage and preneoplastic lesions in rat colon

Background Natural antioxidants present in common foods and beverages have drawn great attention to cancer prevention due to its health benefits, remarkable lack of toxicity and side effects. Copaifera langsdorffii, known as “copaiba”, “capaiva”, or “pau-de-óleo“, belongs to the Leguminosae family and occurs in fields and grasslands in the northern and northeastern parts of Brazil. Biological studies of Copaifera corroborate its widespread use by the population. This paper describes the effects of C. langsdorffii leaves hydroalcoholic extract on the 1,2-dimethylhydrazine (DMH)-induced DNA damage and aberrant crypt foci (ACF) in the colon of male Wistar rats. Methods The hydroalcoholic extract of C. langsdorffii was administered to rats by gavage at daily doses of 20, 40 and 80 mg/kg body weight. To evaluate DNA damage by the comet assay, animals received the C. langsdorffii extract for seven days and a single subcutaneous injection (sc) of 1,2-dimethylhydrazine (DMH) at a dose of 40 mg/kg on day 7. Animals were sacrificed 4 h after injection of DMH, to assess DNA damage. For the ACF assay, animals were acclimatized for one week (week 1) and then treated with the C. langsdorffii extract five times a week for four weeks (weeks 2 to 5). The rats received sc injections of DMH (40 mg/kg) on days 2 and 5 of weeks 2 and 3, to induce ACF. Animals were euthanized at week 5; i.e., four weeks after the first DMH treatment. Results Animals treated with different doses of the C. langsdorffii extract combined with DMH had significantly lower frequency of DNA damage as compared with the positive control (animals treated with DMH only). The percentage of reduction in the frequency of DNA damage ranged from 14.30% to 38.8%. The groups treated with 40 and 80 mg/kg C. langsdorffii extract during and after DMH treatment presented significantly lower numbers of ACF and aberrant crypts compared with the control. Conclusion The C. langsdorffii extract significantly reduced the extent of DNA damage and ACF induced by DMH, suggesting that the extract has a protective effect against colon carcinogenesis.
