A metafísica de Isaac Newton

The general objective of this dissertation is to analyze the metaphysical aspects of "rational mechanics" of Isaac Newton, clarifying, by scientific and philosophical discourse, their main elements, with emphasis to the presence of one entity infinitely rational behind all the phenomena of nature, and to the Newton's insight as certain empiricist which, however, accepts deductions metaphysics; a philosopher-scientist. The specific objectives are detailed below: a) brief presentation of the development of modern science, since the Pre-Socratics, seeking to understand the historical conjecture that enabled the rise of Newtonian mechanics; b) presentation of the elements of scientific methodology and philosophical, aimed at comprehension of certain "Newtonian methodology", understanding how this specific methodology able to present empirical aspects, mathematics, philosophic and religious in communion; c) to understand, from the Newtonian concepts, both concerning man's role in the world as the "notional notions" of mass, space, time and movement, necessary for analysis and understanding of certain metaphysical aspects in the Newtonian physics; d) to present the Newtonian concepts related to the ether, to understand why it necessarily assumes metaphysics characteristics and mediation between the bodies; e) to present and understand the factors that lead the empiricist Newton to assume the religion in his mechanics, as well as, the existence and functions of God in nature, to object to the higher content of his metaphysics; f) to highlight the metaphysical elements of his classical mechanics, that confirm the presence of concepts like God Creator and Preserver of the natural laws; g) at last, to analyze the importance of Newton to the modern metaphysics and the legacy to philosophy of science at sec. XVII to science contemporary

Rosa Luxemburg: marxismo e história

Ao interpretar o marxismo como unidade entre teoria e prática, Rosa Luxemburg lança os fundamentos da sua teoria da ação revolucionária, palavras com que poderíamos sintetizar o seu pensamento político, elaborado numa polêmica ininterrupta com o determinismo economicista da II Internacional.

Guimarães Rosa ou o narrador como performer

Este artigo busca explorar a condição do narrador performer no conto “Sarapalha”, de Guimarães Rosa. A partir da construção das personagens no universo da ficção, parte-se para articulação entre o campo da performance e da literatura, explorando os signos que desestabilizam as categorias de espaço, tempo e ação. A abordagem priva pela aproximação das categorias narrativas com as categorias performáticas do texto, apontando os índices simbólicos e as estratégias de construção e elaboração presentes no universo rosiano. Para tanto, privilegiou-se o cruzamento entre o narrar e o performatizar como ações da escritura, bem como os níveis de materialidade e fisicalidade contidos no conto

Vida e teatro em Guimarães Rosa: Grande sertão: veredas e pirlimpsiquice

Este artigo inicia-se com uma exposição sucinta da metáfora do teatro, tal como aparece em Platão. em seguida, após levantamento dos momentos capitais da literatura, investiga-se a metáfora em Guimarães Rosa, no Grande sertão: veredas e no conto Pirlimpsiquice. No Grande sertão, a atuação no palco é tomada como equivalente ao desempenho na vida. Teatro e vida são, portanto, domínios que se identificam. Para isto, concorrem a religião cristã e o pensamento de Plotino. em Pirlimpsiquice, o Autor investiga por menorizadamente os limites e aproximações entre teatro e vida, sendo que o grau mínimo da metáfora é conferido pelas práticas histórica e cultural. Por fim, retomando a polêmica de Hegel com o platonismo, conclui-se que a representação e a vida estão amalgamadas, numa constante dialetização entre história e cultura.

Estrutura e significado em Uma rosa para Emily, de William Faulkner

Trata-se de uma análise do consagrado conto Uma Rosa para Emily, de William Faulkner, voltada para alguns dos principais aspectos de sua estrutura. Após considerarmos o enredo, discutimos a construção das personagens, com destaque para a protagonista, fazendo um levantamento e comentários sobre possíveis fontes de inspiração, destacando, entre outras, aspectos da biografia da poeta Emily Dickinson, a ficção e a poesia de E. A. Poe, romances de Charles Dickens e Henry James, o conto de Sherwood Anderson e a poesia de William Blake, Emily Dickinson, Robert Browning e John Crowe Ransom, acrescentando paralelos com o conto Bartleby, o escrivão, de Herman Melville. Analisamos, então, o foco narrativo, os símbolos e o significado, ressaltando aqui o desenvolvimento temático da narrativa.

Rosa Luxemburg: revolução e democracia

Y aurait-il un lien indissoluble entre révolution et terreur? de nos jours, une partie de ce qui a été autrefois la gauche y croit Contre l'idée de révolution, saisie corne la source du totalitarisme, on propose le renforcement de la démocratie. Cet article a l'intention de contribuer à ce débat en montrant l'alternative révolutionnaire et démocratique présentée par Rosa Luxemburg. Pour elle la démocratie n'est pas une valeur universelle abstraite mais justement le résultat d'un processus révolutionnaire où les masses prolétariennes, agissant dans la plus large liberté, lancent les fondements d'une nouvelle époque. Néanmoins la révolution allemande où Rosa Luxemburg et Karl Liebknecht ont eu un rôle de premier plan avorte et ils sont assassinés. Cette défaite trace, d'une certaine manière, le destin de l'Allemagne contemporaine.

Rosa Luxemburg: breve perfil de uma revolucionária

O presente texto, que serve de apresentação à série de cartas traduzidas pela A. e publicadas a seguir junto ao original alemão (Karl Kraus), esboça em rápidos traços a personalidade de Rosa Luxemburg, tendo como pano de fundo a cultura do seu tempo. Procura-se sugerir que se Rosa é uma personagem tão rica e interessante, isso deve-se ao amálgama, existente na sua formação, entre a Bildungsbürgertum e a atmosfera revolucionária proveniente da Rússia.

Effects of some mineral deficiencies on the development of the soybean plant, Glycine max (L.) Merril cv Santa Rosa

The present work studies Ca, B and Zn omission on the development of soybean plants (Glycine max (L.) Merrill cv Santa Rosa). The experiment was carried out as hydroponic culture, viith complete Hoagland & Arnon nutrient solution nr. 2 (C), lacking calcium (-Ca), lacking boron (-B) or lacking zinc (-Zn), a total of 4 treatments. Seven samplings were made to determine: total dry matter (g), root dry matter (g), stem dry matter (g) and leaf dry matter (g). Results showed that Ca and B omissions decreased dry weight. Lack of Zn did not affect dry weight.

Effect of type of cuttings and indolbutyric acid on the rooting of rose (Rosa sp. 'Red success') leafy cuttings during two seasons

The objectives of this study were to evaluate the effect of type of cuttings (apical, intermediate and basal) and different concentrations of IBA (indole-3-butyric acid) on rooting of Red success rose (Rosa sp.) leafy cuttings, during two season of cuttings collection (summer and winter). The investigation was carried out in the farm Irmaos Van Schaik in Holambra-SP, Brazil, from February to April and August to October/1993. The experimental design was a randomized block in a factorial arrangement. It consisted of 12 treatments (3 types of cuttings combined with IBA powder in 4 different concentrations - 0, 1000, 2000 and 4000 ppm) with 3 replicates during 2 seasons. The investigation permitted the following conclusions: the apical and intermediate cuttings showed better results in general when compared to the basal ones in both seasons; the average rooting at the transplanting time were 76%, 70% and 47% (summer) and 80%, 69% and 33% (winter) for apical, intermediate and basal cuttings, respectively; the utilization of IBA did not stimulate rooting. The average rooting for the control cuttings reached 85% (summer) and 78% (winter), regardless the type of cuttings.

Effects of rooting media, indolbutyric acid and fertilization on the rooting of rose (Rosa sp. 'Dalas') leafy cuttings

The objectives of this study were to evaluate the effects of rooting media (vermiculite, carbonized rice bark, fenolic spume and sand), presence of IBA (indole-3-butyric acid) and presence of fertilization during the rooting of rose (Rosa sp.) leafy cuttings, Dalas cultivar. This investigation was carried out in Jaboticabal (Sao Paulo State - Brazil) during the period of March to April 1997. The experimental design was a randomized block in a factorial arrangement. It consisted of 16 treatments (the 4 rooting media combined with IBA concentrated solutions - 0 and 1.000 ppm and fertilizer - 0 and commercial product with macro and micronutrients, applied weekly) with 3 replicates. The evaluations were 30 days after cuttings showed that the best rooting percentage occurs in sand (98%), followed by vermiculite (90%) and fenolic spume (87%) and cuttings treated with IBA (95%), while the fertilization showed no promoting effects. The number of cuttings roots wasn't affected with rooting media or DBA treatment, while the fertilization showed effective.

Morphologic characterization and evaluation of the productivity of nine rootstocks of rose bush (rosa spp.)

In Brazil, garden and cut rose bushes are propagated through cuttings or grafting. The rootstocks used in most of the traditional areas of cultivation are not identified, being known just by the vulgar name. There is not any information in the literature on the morphologic characteristics, nor about the productivity of different cultivars on the rootstocks available in Brazil. The objective of this work was to characterize and determine productivity of nine rootstocks (Rosa multiflora 'Paulista'; R. multiflora 'Japones'; R. multiflora 'Iowa'; R. multiflora 'Kopmans'; R. indica 'Mayor'; R. indica x multiflora; R. sp. 'Natual Brier'; R. manetti and R. canina 'Inermis') grafted with 'Versilia' and 'Tineke' scions. Morphologic studies were undertaken to characterize branches of adult plants to determine shape and dimensions of the leaf; number of prickles/15 cm of stem; vigor of the stems; incidence of Diplocarpon rosae (blackspot) and coloration of the leaf. The productivity (number of commercial flowers/plant/month) was evaluated for 6 months (October, 2000 to March, 2001), in the city of Andradas, Minas Gerais State, located at 1251 meters above sea level. Since there was significant difference in just two months for both rootstocks, 'Tineke' and 'Versilia', no rootstocks could be considered inadequate. Nonetheless, in general, the rootstocks that showed a better performance with 'Tineke' were, R. multiflora 'Kopmans' and R. manetti and with 'Versilia', R. multiflora 'Kopmans' and Rosa sp. 'Natual Brier'.

O impacto da pesca do camarão-rosa Farfantepenaeus paulensis (Perez-Farfante) (Decapoda, Penaeidae) nas assembléias de peixes e siris do Parque Nacional da Lagoa do Peixe, Rio Grande do Sul, Brasil

This work evaluates the impact of the pink shrimp Farfantepenaeus paulensis (Perez-Farfante, 1967) fishery on fish and crab assemblages of Lagoa do Peixe National Park, Brazil. We observed that composition of catches is similar to shrimp fisheries using fyke-net at others estuaries of Rio Grande do Sul State: pink shrimp (53%), accessory catches (24%) and bycatch (23%). However, fishery composition showed distinct differences along the saline gradient of the main park's lagoon. Regarding only fish species, the most impacted species in this fishery were Brevoortia pectinata (Jenyns, 1842), Micropogonias furnieri (Desmarest, 1823), and Jenynsia multidentata (Jenyns, 1842). In others estuaries from Rio Grande do Sul, in contrast, the most impacted species were M. furnieri, Genidens barbus (Lacepède, 1803) and Genidens genidens (Cuvier, 1829). The potential impact of the pink shrimp fishery at Lagoa do Peixe National Park seemed to be weaker when compared to shrimp fisheries elsewhere. We believe that the decision to prohibit this fishery at the Lagoa do Peixe National Park should not be based on its potential damage to the fish and crab assemblages but based on the simple fact that Brazilian laws do not allow fisheries inside National Parks.
