Estrategias felinas: discurso poetico X midia na poesia brasileira contemporanea : Armando Freitas Filho e Sebastião Uchoa Leite
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoA presente dissertação analisa na produção textual de Armando Freitas Filho e Sebastião Uchoa Leite o conflito entre a mídia, como veiculadora de discursos homogeneizantes na sociedade, e o discurso poético como voz alternativa, marcada pela singularidade e pelo exercício crítico em relação às noções de sujeito, subjetividade, verdade, discurso. Para isso, foram estudadas principalmente obras escritas nos anos 1980
Savannychapis Freitas 2022, New genus
No full textSavannychapis Freitas New genus Type species: Gaesischia interrupta Urban 1989c [p. 90] Diagnosis: The genus Savannychapis is easily recognizable among the remaining Neotropical genera closely related to Gaesischia (Dasyhalonia Michener, LaBerge and Moure, Florilegus Robertson, Gaesochira Moure and Michener, Hamatothrix Urban, Micronychapis Moure and Michener, Pachysvastra Moure and Michener, Platysvastra Moure, Santiago Urban, and Svastrina Moure and Michener) by (i) the maxillary palpi with three palpomeres (Fig. 2-e); by the (ii) sixth sternum of males with a posterolateral carinae on each side of the median line, approaching, but neither attaining the apex of the sternum nor each other near the median line (Fig. 2-f); (iii) T6 without lateral parts elevated or forming tooths. Among Neotropical Eucerini, the only other genus with the combination of three or fewer palpomeres and carinae on S 6 in some of its species is Melissoptila Holmberg; however, the presence of elevations or tooths on the laterals parts of T6 is a diagnostic character for that genus together to the number of maxillary palpomeres, while Savannychapis lacks elevations on lateral parts of T6. Etymology: The name is a free combination of savanna in reference to the Cerrado (Brazilian savanna), where the type species seems to be endemic, plus the suffix - nychapis regarding its sister genus Micronychapis. Included species: Savannychapis interrupta (Urban 1989) comb. n. Distribution: This species seems to have a broad distribution in the domain of Cerrado (Brazilian savanna), with records in the Brazilian states of Bahia, Mato Grosso, and Minas Gerais.Published as part of Freitas, Felipe V., 2022, New genus and subgenus of South American long-horned bees (Apidae, Eucerini), pp. 595-600 in Zootaxa 5196 (4) on pages 596-597, DOI: 10.11646/zootaxa.5196.4.8, http://zenodo.org/record/723582
Gaesischia (Gaesischioides) Freitas 2022, New subgenus
No full textGaesischia (Gaesischioides) Freitas New subgenus Type species: Eucera hyptidis Ducke 1910 [p. 93] Diagnosis: Gaesischia (Gaesischioides) hyptidis has five segmented maxillary palpi as in Gaesischia s. str. and G. (Gaesischiana), different from G. (Gaesischiopsis), which have four segmented maxillary palpi; the pilosity is predominantly pale in both sexes, in the remaining subgenera it is variable. Males: clypeus yellow; labrum black, generally with a small yellow/whitish area on its disc (Fig. 1-f); the sixth metasomal sternum with subapical carinae running parallel to posterior margin, broadly interrupted by the median line, and with a tuft of hairs on the disc (Fig. 1-e), these characters, in combination with those shared by both sexes, form a unique combination among the subgenera of Gaesischia. Females: clypeus black with a yellow triangular area on its apex (Fig. 1-b), which differentiates it from the remaining species of Gaesischia with five maxillary palpomerers and a yellow apical band on the clypeus. Etymology: The subgenus name is a free combination of the generic name (Gaesischia) and the Latin suffix -oides, which means resemblance or likeliness. Included species: Gaesischia (Gaesischioides) hyptidis (Ducke 1910). Distribution: The species was described by Ducke (1910) and redescribed by Urban (1968) based on specimens from the state of Ceará, Brazil. There are also records from the states of Sergipe and Rio Grande do Norte, suggesting that this species is associated with the Caatinga in northeastern Brazil. Comments: Gaesischia hyptidis, as highlighted in previous treatments of Gaesischia taxonomy, is a distinct species (Moure & Michener 1955). It was firstly positioned in the subgenus G. (Agaesischia) together with G. patellicornis, but with a caveat that this was a tentative decision (Moure & Michener 1955). It was later transferred to Gaesischia s. str. (Laberge 1958; Urban 1968a) but still retained under G. (Agaesischia) in Moure’s Catalog for Neotropical bee species (Urban et al. 2012). According to the results of Freitas et al. (in prep.), it is recovered as the sister lineage of the clade containing Gaesischia s. str. + G. (Gaesischiopsis), or as sister to G. (Gaesischiopsis), highlighting its distinctiveness, as already noticed by Moure & Michener (1955), when speculating on the possible proximity of G. hyptidis and G. (Gaesischiopsis). The easiness of identifying both males and females of G. hyptidis using the two identification keys available in the comprehensive reviews of Gaesischia conducted by Urban (1968, 1989c) reinforces the distinctiveness of this species.Published as part of Freitas, Felipe V., 2022, New genus and subgenus of South American long-horned bees (Apidae, Eucerini), pp. 595-600 in Zootaxa 5196 (4) on page 596, DOI: 10.11646/zootaxa.5196.4.8, http://zenodo.org/record/723582
On The Behavior Of Clamped Plates Under Large Compression
No full textWe determine the asymptotic behavior of eigenvalues of clamped plates under large compression by relating this problem to eigenvalues of the Laplacian with Robin boundary conditions. Using the method of fundamental solutions, we then carry out a numerical study of the extremal domains for the first eigenvalue, from which we see that these depend on the value of the compression, and start developing a boundary structure as this parameter is increased. The corresponding number of nodal domains of the first eigenfunction of the extremal domain also increases with the compression.MAT
Sertania lambedor Freitas 2017, comb. nov., stat nov.
No full textSertania lambedor (P. Jauffret, J. Jauffret & Pessôa, 2008), comb. nov., stat nov. (Figs 9–12, 25–26, 31–32, 42–44) “ Emesis ” jaibensis lambedor P. Jauffret, J. Jauffret & Pessôa, 2008. Lambillionea CVII(4):506–508. Figs. 13–16. Type locality: Fazenda Lambedor, Santa Quitéria, Ceará, Brazil. Holotype male, Allotype female: MPEG. Diagnosis. Forewing length: males 10–13 mm (n = 3), females 13–14 mm (n = 2). Sertania lambedor comb. nov., stat nov. is more similar and closely related to S. jaibensis, however, differences in the DNA barcode are appreciable (2.67%, Table 2) and adults can be easily distinguished from the latter by the bright yellow coloration in males and females (Figs. 9–12). Furthermore, S. jaibensis presents an infusion of red-orange scaling on the male dorsal surface and light yellow scaling on the female. The ventral FW discal area of the male is brick red and the HW discal area lighter white with reddish scaling, and the post-medial area darker with black scaling. The submarginal row of brown spots is more apparent. The female ventral surface has light orange ground color on the FW and darker orange infused with white scaling on HW. Margin of uncus straight in S. lambedor (Fig. 25), in S. guttata and S. jaibensis the margin of uncus present a dorsal projection (Figs 21, 23). Female genitalia of S. jaibensis present ostium bursae with oval opening and pointed signa (Figs 29–30), while S. lambedor has the ostium bursae with circular opening and less pointed signa (Figs 31–32). Biology and distribution. Sertania lambedor was observed flying rapidly about a meter above the ground along a dry stream bed in the caatinga. Adults landed on small flowers for short periods of time, being difficult to approach, thus making capture difficult (Jauffret et al. 2008). This species was recorded in six localities of caatinga (Fig. 37) in northeast Brazil, including the Parque Nacional do Catimbau, Pernambuco, and Parque Nacional da Serra das Confusões, Piaui (Kerpel et al. 2014, Nobre & Schlindwein 2016).

Arte pública e paisagem urbana de Florianópolis, SC, Brasil
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Urbanismo, História e Arquitetura da CidadeEste volume de escritos faz parte de um processo de pesquisa que começou a tomar forma em fins de 2005 e que, dentre conexões possíveis, escolheu por percorrer algumas, referentes ao campo da Arte Pública, intensificando-se em seu recorte na cidade de Florianópolis, SC. A Arte Pública é aqui considerada não como um tipo - mas como um campo expandido das artes, configurando níveis de atuação. Permeando os espaços estriados e lisos da cidade, a Arte Pública apresenta a possibilidade de trabalhar no espaço do entre, atuando na paisagem cultural - do habitus e do caráter - da cidade. E, se uma obra de Arte Pública em si não consegue criar um lugar, ao menos pode oferecer a possibilidade de dotá-lo de caráter e significado, podendo ser trabalhada em diferentes níveis de atuação. Um destes níveis é sua gestão, por parte do poder público. No sentido do escrito acima, a escolha da cidade de Florianópolis torna-se justificada para um olhar mais atento às suas peculiaridades. Cidade de vistas panorâmicas espetaculares, apresenta uma rápida descaracterização de referenciais paisagísticos, que a está esvaziando de significados. Sua apropriação, de maneira devastadora, pelo forte mercado imobiliário, está ajudando a destruir sua geografia e paisagem natural. A gestão municipal de obras de arte em Florianópolis, capitaneada pela recente Comissão Municipal de Arte Pública, ainda se resume a uma única lei, que trata da inserção de obras de arte em edificações. Porém, um embrião de gestão e política urbana pode ser evidenciado. Esta dissertação discorre sobre a multiplicidade de ações concernentes ao campo da Arte Pública na cidade de Florianópolis, SC, com ênfase na questão da gestão municipal
Moneuptychia vitellina Freitas & Barbosa, new species
No full textMoneuptychia vitellina Freitas & Barbosa, new species (Figs. 2 E, 6, 7) Adult: Diagnosis. Moneuptychia vitellina n. sp. is similar to some species in the Euptychoides castrensis species complex. However, they are easily distinguished from the above species, and from all other known species of Moneuptychia, by the broad yellow outlining the ocelli on the ventral hind wing. Descriptions of adults: Male (Figs. 2 E, 6). Forewing length 17–19 mm (n = 7); hind wing length 13–14 mm (n = 7). Eyes naked, entirely brown. Palpus length 2.0 times head height, beige, with long dark brown and white hairs. Antenna of males 8 mm in length, with 35 antennomeres extending to mid-costa; shaft rust brown, dorsally covered by dark brown scales, club with 12 antennomeres, not conspicuously developed. Male foreleg covered by long beige hairs. Wings with dorsal ground color brown with few markings, restricted to marginal and submarginal lines in both wings; forewing with no additional markings; hind wing with two large black ocelli outlined by an orange ring in CuA 1 -CuA 2 and CuA 2 - 2 A. Forewing of males presenting a conspicuous callus on SC vein, close to distal end of swollen portion of vein. Ventral wings mostly brown; forewing crossed by two dark brown lines, first indistinct, extending from discal cell to 2 A one third from base; second extending from costa to 2 A at two thirds from wing base; a dark brown irregular submarginal line and a brown regular marginal line extending from costa to 2 A; ocelli absent. Hind wing crossed by two dark brown nearly straight lines from costa to anal margin, first onethird from wing base, second two-thirds from it; second crossing line delimiting a lighter marginal area; a brown irregular submarginal line and a brown regular marginal line extending from costa to 2 A; a series of five black ocelli outlined by a broad yellow ring can be found in M 1 –M 2 (ocellus 1), M 2 –M 3 (2), M 3 –CuA 1 (3), CuA 1 –CuA 2 (4) and CuA 2 – 2 A (5); ocelli 2 and 3 small; in some individuals ocellus 2 can be nearly absent, reduced to few yellow scales with one white scale in center; ocellus 2 usually double (when visible); ocelli 1, 4 and 5 larger than other; ocelli 1 and 4 with double white pupil. Hind wing outer margin slightly wavy. No conspicuous androconial scales or patches observed. Male genitalia (Fig. 7). Saccus short and slender in ventral view; tegumen rounded; gnathos absent; appendix angularis extremely conspicuous projecting posteriorly as a long process; uncus elongated; valvae elongated, narrowing towards end, and with a single pointed process projecting internally (Figs. 7 B–C); aedeagus slightly curved upwards, with a conspicuous triangular projection in left near tip (Fig. 7 E); cornuti absent; juxta membranous. Female (Fig. 6). Forewing length 19–20 mm (n = 5); hind wing length 15–18 mm (n = 5). Body entirely dark brown. General color and pattern very similar to that of males, with wings more rounded. Remarks on color variation. Variation on the dorsal wing surfaces is virtually absent. The ventral surface of both wings shows some variation in intensity of the yellow rings outlining the ocelli, and size of the small ocelli (as described above in both sexes). Habitat, behavior and natural history. Moneuptychia vitellina n. sp. was observed in partially shaded areas, with open understory covered by grass (Fig. 2 C). Adults of both sexes were observed flying near the edges of the shaded areas, where males perched and chased other males, but usually avoiding open areas with direct sunlight. Adults were observed perching on leaves from 10 to 50 cm above ground (Fig. 2 E). Males are apparently territorial, and were observed interacting with other males, when it was possible to hear a clicking noise when two or more males flew together. No courtship behavior was observed. Distribution. The species is known from the Serra da Mantiqueira, in a narrow region extending from Campos do Jordão (São Paulo) to Itatiaia (Minas Gerais and Rio de Janeiro), and also from the Serra da Bocaina, in altitudes from 1550 to 1850 m. Etymology. The specific epithet is an adjective derived from the Latin (vitellus = egg yolk), and refers to the large amount of yellow outlining the ocelli on the ventral hind wing of both sexes.
