Contribution of the radical-complex mechanism to the rate of the reaction CH3 + O-2 (+ M) -> CH3O2 (+ M) at high pressures.
No full textEarlier experimental studies of the falloff curves of the reaction CH3 + O-2 M) -> CH3O2 ( M) in the bath gases M = Ar and N-2 (Fernandes et al., J. Phys. Chem. A 2006, 110, 4442), in addition to the usual behavior of the energy-transfer (ET) mechanism, showed first evidence for a participation of the radicalcomplex (RC) mechanism in the reaction at pressures above about 300 bar and at temperatures below 400 K. By extending these measurements to the bath gas M = CO2, more pronounced deviations from the ET mechanism were now observed. This unambiguously confirms the presence of the RC mechanism at high pressures in a medium-sized molecular system, analogous to earlier observations for larger systems such as the dimerization of benzyl radicals (Luther et al., Phys. Chem. Chem. Phys. 2004, 6, 4133)
SPM in situ data at Patos Lagoon estuary in 4 stations: Feitoria, Marambaia, Praticagem, and Porto Rei - Fernandes (1998)
No full textFernandes (Fernandes, E. H.: Modelling the Hydrodynamics of the Patos Lagoon, Brazil, Ph.D. thesis, University of Plymouth, 2001) aimed to calibrate the hydrodynamic model TELEMAC for the Patos Lagoon for the first time. The author executed SPM field measurements at 4 stations: Feitoria, Marambaia, and Praticagem (between 27-29 October, 1998), and at Porto Rei (between 05-06 November, 1998) and measurements were carried out at the surface, middle depth and bottom using horizontal bottle samplers. These consist of a simple PVC pipe closed at the ends by rubber stoppers and released by a messenger sent from the surface. Sub-samples were stored in plastic bottles for further filtration and determination of SPM content. Samples were filtered through CA filters of 45 μm pore size as in Baumgarten et al. (Baumgarten, M., Rocha, J., and Niencheski, L.: Manual de Análises em Oceanografia Química, FURG, Rio Grande, Brazil, 1996)
Falloff curves for the reaction CH3 + O2 (+M) -> CH3O2 (+M) in the pressure range 2-1000 bar and the temperature range 300-700 K.
No full textThe reaction CH3 + O-2 (+M) -> CH3O2 (+M) was Studied in the bath gases Ar and N-2 in a high-temperature/high-pressure flow cell at pressures ranging from 2 to 1000 bar and at temperatures between 300 and 700 K. Methyl radicals were generated by laser flash photolysis of azomethane or acetone. Methylperoxy radicals were monitored by UV absorption at 240 nm. The falloff curves of the rate constants are represented by the simplified expression k/k(infinity) approximate to [x/(1 + x)]F-cent(1/{1+[(logx)/N]2}) with x = k(0)/k(infinity) F-cent approximate to 0.33, and N approximate to 1.47, where k(0) and k(infinity) denote the limiting low and high-pressure rate constants, respectively. At low temperatures, 300400 K, and pressures > 300 bar, a fairly abrupt increase of the rate constants beyond the values given by the falloff expressions was observed. This effect is attributed to a contribution from the radical complex mechanism as was also observed in other recombination reactions of larger radicals. Equal limiting low-pressure rate constants k(0) = [M]7 x 10(-31)(T/300 K)(-3.0) cm(6) molecule(-2) s(-1) were fitted for M = Ar and N-2 whereas limiting high-pressure rate constants k(infinity) = 2.2 x 10(-12)(T/300 K)(0.9) cm(3) molecule(-1) s(-1) were approached. These values are discussed in terms of unimolecular rate theory. It is concluded that a theoretical interpretation of the derived rate constants has to be postponed until better information of the potential energy surface is available. Preliminary theoretical evaluation suggests that there is an "anisotropy bottleneck" in the otherwise barrierless interaction potential between CH3 and O-2
Experimental and modeling study of the temperature and pressure dependence of the reaction C2H5 + O2 (+ M) → C2H5O2 (+ M).
No full textThe reaction C2H5 + O2 (+ M) → C2H5O2 (+ M) was studied at 298 K at pressures of the bath gas M = Ar between 100 and 1000 bar. The transition from the falloff curve of an energy transfer mechanism to a high pressure range with contributions from the radical complex mechanism was observed. Further experiments were done between 188 and 298 K in the bath gas M = He at pressures in the range 0.7-2.0 Torr. The available data are analyzed in terms of unimolecular rate theory. An improved analytical representation of the temperature and pressure dependence of the rate constant is given for conditions where the chemical activation process C2H5 + O2 (+ M) → C2H4 + HO2 (+ M) is only of minor importance
Experimental and modelling study of the recombination reaction H+O(2)(+ M) -> HO(2)(+ M) between 300 and 900 K, 1.5 and 950 bar, and in the bath gases M = He, Ar, and N(2)
No full textThe recombination reaction H + O(2) (+ M)-HO(2) (+ M) was studied by laser. ash photolysis in a high pressure flow cell, over the temperature range 300-900 K, the pressure range 1.5-950 bar and in the bath gases M = He and N(2). Earlier experiments by Hahn et al. ( Phys. Chem. Chem. Phys. 2004, 6, 1997) in the bath gas M = Ar were also extended. The data were analyzed in terms of unimolecular rate theory employing new calculations of relevant molecular parameters. Improved energy transfer parameters for the bath gases M = He, Ar, N(2), and H(2)O could thus be obtained and complete fallo. curves were constructed. In the case of water, the high pressure rates well connect with pulse radiolysis results obtained in supercritical water by Janik et al

It grows in forest formations of Amazonian forest, Atlantic rain forest, and Cerrado domains, where it can grow in shaded and sunny areas at 1– 720 m. Notes:— The most notable character of M. maxonianum is the dense cover of sessile to stalked glands on the abaxial surface of the laminae, and having the sporangial stalks glabrous or with inconspicuous filamentous, septate structures. In these characters it differs from the similar M. longifolium, which shares the same shape of lamina and pinnae, but is characterized by having glands and trichomes (sometimes only trichomes) on the abaxial surface of the lamina and sporangial stalks with long, acicular trichomes. Another species that also has glandular trichomes on the abaxial surface of the lamina is M. falcatum Liebmann (1849: 183). However, it differs from M. maxonianum by having longer pinna stalks and acicular and erect trichomes on the costae.Published as part of Fernandes, Rozijane Santos, Yesilyurt, Jovita Cislinski & Salino, Alexandre, 2014, New species and combinations in Meniscium (Thelypteridaceae), pp. 1-11 in Phytotaxa 184 (1) on page 9, DOI: 10.11646/phytotaxa.184.1.1, http://zenodo.org/record/515317
Garn! I'm a good girl, I am: um estudo descritivo de duas traduções do cockney em Pygmalion de Bernard Shaw para o português brasileiro
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Esta pesquisa está inserida nos Estudos Descritivos de Tradução e tem como objetivo analisar duas traduções para o português brasileiro da peça Pygmalion de Bernard Shaw. Mais especificamente, analisar como os dois tradutores brasileiros Miroel Silveira (1964) e Millôr Fernandes (2005) traduziram o dialeto cockney da personagem Eliza Doolittle. Esta variação linguística específica tem associações geográficas e culturais. O cockney é a forma de inglês falado na área de East End de Londres pela chamada classe trabalhadora e tem um papel central na narrativa de Pygmalion. O modelo teórico metodológico proposto por Lambert e Van Gorp (1985) foi utilizado para a análise das traduções. A hipótese inicial levantada por este estudo foi a de que os tradutores, apesar de utilizarem abordagens diferentes, não apagariam os traços dialetais, pela importância desse elemento no desenvolvimento da peça, o que vai de encontro às observações de Milton (2002) no que se refere à prática comum de apagamento de dialetos na tradução literária no Brasil. O que se verificou pela análise é que Miroel Silveira ambientou a peça no Rio de Janeiro e traduziu o cockney de Eliza funcionalmente para um pseudodialeto suburbano com marcação da oralidade principalmente pelo uso de gírias, deixando bem marcado, dessa forma, seu background social, enquanto Millôr Fernandes optou por traduzir funcionalmente o cockney a um pseudodialeto caipira, porém mantendo a peça em Londres. Abstract : This research is embedded within the Descriptive Translation Studies and aims at analyzing two translations into Brazilian Portuguese of the play Pygmalion by Bernard Shaw. Specific attention is given to how the two Brazilian translators Miroel Silveira (1964) and Millôr Fernandes (2005) translated the cockney accent of the character Eliza Doolittle. This linguistic variation has specific geographical and cultural association. Cockney is the form of English spoken in London's East End area by the so-called working class and has a central role in the narrative. The methodological model proposed by Lambert and Van Gorp (1985) was used for the analysis of the translations. The initial hypothesis formulated that the two translations, despite the different approaches, would not erase the dialect due to its importance to the development of the play, going against observations made by Milton (2002) to what refers to the common practice of erasing dialects in literary translations in Brazil. The analysis verified that Miroel Silveira changed the setting of the play to Rio de Janeiro and translated Eliza?s cockney accent functionally to a suburban pseudo dialect with orality marks mainly by slang usage, marking the social background. On the other hand, Millôr Fernandes chose to translate cockney functionally into a pseudo ?caipira? dialect, however, keeping the setting of the play in London

It usually grows inside or along the edges of tropical evergreen forest formations, on hillsides, often along trails, at 350–1050 m. Notes:— Meniscium cocleanum was, until this study, the only species of the genus known to have buds in the distal pinnae. Smith & Lellinger (1985) stated that the affinities of this species are uncertain. The new species described in this paper (Meniscium triangularis) also has distal proliferous buds, however, M. cocleanum has completely glabrous laminae whereas M. triangularis has a dense indument of scales and trichomes abaxially. Other differences have been previously discussed above.Published as part of Fernandes, Rozijane Santos, Yesilyurt, Jovita Cislinski & Salino, Alexandre, 2014, New species and combinations in Meniscium (Thelypteridaceae), pp. 1-11 in Phytotaxa 184 (1) on pages 7-8, DOI: 10.11646/phytotaxa.184.1.1, http://zenodo.org/record/515317
