A sinfonia do sagrado em Castro Alves: (Deus, Eros e mãe em Os escravos)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.No presente trabalho realiza-se uma leitura intertextual entre a Bíblia e Os escravos, coletânea de poemas de teor abolicionista do poeta romântico Antônio Frederico de Castro Alves (1847-1871), objetivando demonstrar que os textos poéticos arquitetam-se na desconstrução e reconstrução dos textos bíblicos. A leitura dos poemas centra-se nos personagens: Deus, Eros e Mãe, os quais conformam uma trindade poética/sagrada. A pesquisa divide-se em três movimentos: Prelúdios do sagrado no Romantismo, Tríade melódica e À guisa de coda: trindade poética. No primeiro efetuam-se algumas aproximações ao conceito do sagrado e aos Romantismos francês e brasileiro. O seguinte corresponde à leitura das composições, através das linhas melódicas: A dualidade de Deus, A ambivalência de Eros e O duplo calvário da Mãe escrava. E no último movimento amalgamam-se as inter-relações entre a trindade cristã e poética e os dramas bíblico e poético

Large-eddy simulation of dispersion from surface sources in arrays of obstacles
No full textTowards meeting the objective of simulating heat transfer processes in urban areas, the study of dispersion from a scalar (ground) surface area source has been addressed as a first step, as dispersion from such a source is in some ways analogous to heat transfer from the surface. Two different urban-like geometries are considered in this study: an array with uniform height cubes and an array with random height cuboids. Some point measurement dispersion experiments in a wind tunnel have previously been carried out in identical arrays using a naphthalene sublimation technique. Large-eddy simulations (LES) of these experiments have been performed as a validation study and the details, presented here, demonstrate the influence of the roughness morphology on the dispersion processes and the power of LES for obtaining physically important scalar turbulent flux information

Channel flow over large cube roughness: a direct numerical simulation study
No full textComputations of channel flow with rough walls comprising staggered arrays of cubes having various plan area densities are presented and discussed. The cube height h is12.5% of the channel half-depth and Reynolds numbers (u? h/?) are typically around 700 – well into the fully rough regime. A direct numerical simulation technique, usingan immersed boundary method for the obstacles, was employed with typically 35 million cells. It is shown that the surface drag is predominantly form drag, which is greatest at an area coverage around 15%. The height variation of the axial pressure force across the obstacles weakens significantly as the area coverage decreases, but is always largest near the top of the obstacles. Mean flow velocity and pressure data allow precise determination of the zero-plane displacement (defined as the height at which the axial surface drag force acts) and this leads to noticeably better fits to the log-law region than can be obtained by using the zero-plane displacementmerely as a fitting parameter. There are consequent implications for the value ofvon K´arm´ an’s constant. As the effective roughness of the surface increases, it is also shown that there are significant changes to the structure of the turbulencefield around the bottom boundary of the inertial sublayer. In distinct contrast to twodimensional roughness (longitudinal or transverse bars), increasing the area density of this three-dimensional roughness leads to a monotonic decrease in normalized vertical stress around the top of the roughness elements. Normalized turbulence stresses in the outer part of the flows are nonetheless very similar to those in smooth-wallflows

Diagnosis. Carapace (Fig. 16 E, F) subtrapezoidal, convex dorsally, 1.2–1.3 wider than long; front bilobed, with shallow median cleft; anterolateral margins arcuate, minutely granular with granules higher along lateral margins, without distinct lobes or teeth. Eye peduncle (Fig. 26 C) filling orbit, short, immobile; cornea reduced, with reduced pigmentation. Posterior margin of epistome (Fig. 26 C) with semicircular median lobe with deep median fissure, semicircular lateral margins. Third maxilliped (Fig. 33 E) merus subquadrate, ischium subrectangular, slightly longer than merus. Proportionally short ambulatory legs (Fig. 16 E, F); P5 merus 0.7 cl. Chelipeds (Figs. 16 E, F; 45G, H) subequal in length, slightly dissimilar in females, heteromorphic in males; fingers of minor chela (Fig. 45 H) subcircular in cross-section, scissor-like, cutting margins with small teeth; dactylus of major chela of males (Fig. 45 G) curved, forming wide, round gap when closed, reduced teeth. Ventral surface of cheliped merus with row of 5, 6 large pointed tubercles along outer margin (Fig. 42 N). Inner margin of cheliped carpus with short distal tooth (Fig. 16 E, F). Fused thoracic sternites 1, 2 (Fig. 54 C) semicircular, broad, long. Male pleon (Figs. 54 C; 61C) with proportionally short telson. G1 (Fig. 77 I‒K) slender, slightly curved, with short spinules.

Sterno-pleonal cavity of female (Fig. 91 F) deep, vulvae relatively close together, located on outer margins of cavity close to suture 5/6. Remarks. Statommatia malagasy n. sp. is externally similar to S. apta, notably in the form of the carapace and chelipeds. It can be distinguished from S. apta, however, by its proportionally shorter and stouter ambulatory legs, especially the merus (Fig. 16 E, F) (relatively more slender and longer in S. apta, Fig. 16 A‒C), somite 6 of the male pleon is more quadrate, being not much wider than long (Fig. 54 C) (rectangular, being distinctly wider than long in S. apta; Fig. 54 A, B), presence of sharp teeth on the ventral surface of the cheliped meri (low granules in S. apta), and the G1 is more slender and longer (Fig. 77 I‒K) (relatively stouter and shorter in S. apta, Fig. 77 A‒C). Their known ranges are widely separated, with S. malagasy n. sp. in Madagascar and S. apta in Philippines. Distribution. Known only from Madagascar.

It is clear now that what Zarenkov (1972: 238, fig. 3) calls “ <i>Hephthopelta cavimanus</i> ” is actually <i>Chasmocarcinops gelasimoides</i> Alcock, 1900. His figures of a granular carapace with a conspicuously short front and composed of two convex lobes with a deep median cleft (Zarenkov, 1972: fig. 3Cp; cf. Ng & Castro, 2016: fig. 9A, C, E–H); the largest male chela possessing strongly curved fingers with a large gape (Zarenkov, 1972: fig. 3ch; cf. Ng & Castro, 2016: figs. 9B, 40A, C); a distinctive, slender, and elongated third maxilliped with the merus much smaller than the ischium (Zarenkov, 1972: fig. 3IIImxp; cf. Ng & Castro, 2 016: fig. 30E, F); and male pleon (Zarenkov, 1972: fig. 3Abd; cf. Ng & Castro, 2016: fig. 51F) agree very well with what has been described and figured for <i>Chasmocarcinops gelasimoides</i> by Ng & Castro (2016). Zarenkov’s (1972: fig. Ipl) figure of a G1 is almost certainly for this species as well, the number “3” probably accidentally left out; it was positioned just under his figure 3Cp. This G1 looks exactly like that figured for <i>Chasmocarcinops gelasimoides</i> by Ng & Castro (2016: fig. 70A–D). Zarenkov’s (1972: 238) specimens of “ <i>Hephthopelta cavimanus</i> ” were collected from waters 7–42 m, a typical depth range for <i>Chasmocarcinops gelasimoides</i> but shallower than what has been reported for adult <i>Chinommatia cavimanus</i> s. str. (123–549 m) (Ng & Castro, 2016: 65).</p>Published as part of <i>Ng, Peter K.
