O sublime e o problema da modernidade em Pedro Kilkerry

Current paper discusses manifestations of the sublime in Pedro Kilkerry´s poetry as one of the distinguishing characteristics within the Parnassian orientations predominant in his cultural context. The particular way that Kilkerry employs the sublime´s expedients demonstrates the dialogue of his poetry with Romantic ideals, whose traits in his lyrical stance are directly linked to Symbolist influence, far from traditional Parnassian models. The sublime in Kilkerry develops through an elliptical and suggestive language that demonstrates the impossibility of the ideal being directly expressed and shows the affinity of his poetic work with the idealist crisis that marks post-Romantic poetry and provides the basis on which the poetics of Modernity is structured. The poetry of Pedro Kilkerry develops within a complex zone of convergence between the models provided by the Parnassian aesthetic, Romantic idealism with an atavic presence to Symbolism, and the search for new answers to old idealistic concerns. The meeting of these three conflictive currents, perceptible in the manifestations of the sublime in Pedro Kilkerry´s poetry, demonstrates his lyrical sensitivity to the trends of Modernity.

Diel Variation in Abundance and Size of the South American Red Shrimp Pleoticus Muelleri (Spence Bate, 1888) (Decapoda, Solenoceridae) in the Ubatuba Region, Southeastern Brazil

Diel variation in the abundance and size of Pleoticus muelleri in the Ubatuba region was investigated during 2000. During each season of the year, sampling was conducted during the day and at night at 8 depths, from 5 to 40 m. The estimated number of shrimp was 955 individuals, 272 collected during the day and 683 at night. There was a difference in the abundance of P. muelleri between day and night (χ², p=2.33E-40). The abundance during the day and at night differed by season with the exception of the spring (χ², p=0.06). The abundance during both periods also differed by depth, except at 15 and 30 m, where it was not significant (χ², p=0.84 and 0.06, respectively). The shrimp caught at night were generally smaller than those caught during the day (Kolmogorov-Smirnov, p<0.01). Pleoticus muelleri juveniles were found primarily at night. This tendency could have influenced the lower mean size for this period. The sediment type and the bottom temperature appear to influence the behavior of this species and consequently the catch rate during the periods analyzed.

Population ecology of the planktonic shrimp lucifer faxoni borradaile, 1915 (crustacea, sergestoidea, luciferidae) of the southeastern coast of brazil

Luciferid shrimps have short life spans and a rapid turnover of generations, engage in sequential spawning, and protect their eggs during incubation. This study investigates the ecology of Lucifer faxoni Borradaile, 1915 in the littoral zone, Ubatuba region, São Paulo. Sampling was conducted monthly from July 2005 to December 2006 using a Renfro net trawled over a distance of 50 m for a total sampling effort of 50 m² at each station. Nine stations were sampled, ranging from 1 to 15 m deep. Three stations each were grouped into zones 1, 2 and 3 (Z1, Z2 and Z3). Monthly values of salinity, temperature and rainfall were recorded at each station. The pre-buccal somite length (SL) of each specimen was measured. The results showed that in shallower zones (Z1 and Z2), 6306 individuals were captured, whereas in the deeper zone (Z3), 3808 specimens were captured, but no significant differences in SL was detected between the specimens from Z1 and Z2 and those from Z3 (ANOVA, p=0.25). The abundance of shrimps did not differ significantly between seasons (Tukey’s test, p=0.02) except in the spring. The sex ratio differed significantly over the seasons (χ², p<0.05). The results were closely associated with environmental factors with respect to the spatial and seasonal distribution of L. faxoni. Rainfall affected salinity directly, and contributed to the displacement of these shrimps to deeper areas.

Sucessão estratigráfica e tratos de sistemas do Membro Romualdo, porção leste da Bacia do Araripe, nordeste do Brasil

Located in northeastern Brazil, the evolution of Araripe Basin has been associated with the fragmentation of Gondwana and opening of the South Atlantic. The Santana Formation belongs to the post-rift sequence of the basin and is characterized by the presence of laminated limestones in the lower portion (Mb. Crato), evaporite (Ipubi) and siliciclastics (Mb. Romualdo). For better understanding of the Romualdo's stratigraphy, depositional environments and tract of systems, a stratigraphic analysis was made with representative columnar sections of the unit. Sedimentary facies have been described in detail, as well as paleocurrents measured at different stratigraphic levels. It was found that the contact of Mb. Romualdo with the carbonate-evaporite section (Mbs. Crato and Ipubi) is a unconformity, evidenced by residual lags and thin layers of conglomerates above the contact. Above the conglomeratic levels predominate fine sandstones / medium interlayered with calciferous green shales. The percentage of shales increases towards the top, featuring retrogradational stacking culminating in layers of coquinas, excellent stratigraphic mark in the basin. Thin layers of coquins of gastropods comprising equinoids, located on the shale section, present in three sections marine deposits are associated with surfaces ravine. The upper section is characterized by recurrent facies of green shales, sandstones intercalated with sandstones progressively become more frequent towards the top of the unit, featuring the regressive part of the cycle. The sandstones present cross-stratification, often with mud clasts and clay layers in the foresets, and beddings of flaser type and wavy in heterolitic facies, suggesting the action of tidal currents. Paleocurrents measured in the sandstones show gaps with opposite flow directions outlining bipolar standards, which reinforce the interpretation of shallow marine environment influenced by tides during the sedimentation...

Paleocorrentes e paleogeografia do Grupo Aerado, cretáceo inferior da Bacia Sanfranciscana

The Areado Group of the Sanfranciscana Basin is a Lower Cretaceous continental sedimentary system that is correlated to the Brazilian Pre-Salt beds. The Aerado Group is composed of Abaeté, Quiricó and Três Barras formations. Paleocurrent data for the Areado Group were previously presented, although not systematically which prevented significative interpretations on the basin paleogeography. This work attempts to systematically evaluate paleocurrent data, aiming to recognize depositional environment and paleogeographic reconstruction, based on the sedimentary facies and paleocurrents measurements along vertical profiles. Fluvial paleocurrents of the Abaeté Formation indicate paleoflows towards NW whereas aeolian palecurrents of the Três Barras Formation show paleowinds towards SW. The depositional systems interpreted for the Areado Group were: braided river, alluvial fan, lacustrine, playa lake, fluvial-deltaic and aeolian. The combined analyses of facies and paleocurrents allowed a reliable paleogeographic reconstruction of the basin, with paleodip towards northwest, paleowinds towards south-southwest and source-area located at southeast. These results indicate that paleowinds were orthogonal to paleostream, but parallel to depositional strike of the basin. The interpreted depositional systems characterize a desert environment during the Abaeté sub-basin times. The association of dunes and wet interdunes followed by large scale dunes and dry interdunes suggests a decrease in humidity towards the top of the Três Barras Formation, with a dry aeolian system onlapping the basement. The observed decrease of humidity in Sanfranciscana Basin may reflect local or regional paleoclimatic changes during the opening of the South Atlantic, but this assumption is only tentative

Fishes of Paranagua Estuarine Complex, South West Atlantic

The objective of this work was to present an updated checklist of the currently known fishes in the Paranagua Estuarine Complex (PEC) and provides comments on conservation status for the treated species. We used a large dataset derived from a pool of studies which have been conducted within there along the last 30 years. Each study was based on monthly samplings and conducted in several estuarine habitat; thus, the pool covers practically all estuarine habitats and takes into account the seasonal cycle in the system. The PEC ichthyofauna represents a mixture between that fauna typical from the tropical Brazilian coast and that with affinities of temperate Argentinean and Uruguayan zones. The PEC harbors a rich fish fauna of 213 species, inserted in the families that are common along the Brazilian coast. Only a minor part (8%) of the PEC fish fauna was evaluated as regards the conservation status, mostly because of the lack of basic biological and ecological information for most species. Despite part of the among-estuaries differences are due to different and incomplete sampling efforts, the richness in the PEC is surprisingly higher than other systems in Brazil and around world, which emphasize the importance of the region for global biodiversity conservation.

Variação do espectro das ondas de Rossby na região da frente Brasil-Malvinas

A média global da variação na quantidade de calor armazenado nos oceanos observada recentemente é positiva (Cabanes et al., 2001; Cazenave & Nerem, 2004), porém, sua distribuição espacial não é homogênea (Polito & Sato, 2008). O calor armazenado está associado, via expansão térmica, à altura da coluna d'água. Portanto, variações espaciais na tendência do calor armazenado tem como consequência mudanças na inclinação da superfície que, por sua vez, implicam em variações nas correntes geostróficas e portanto na energia cinética associada a fenômenos de meso e larga escala. Polito & Sato (2008) observaram tendências predominantemente positivas na amplitude de ondas de Rossby e vórtices de mesoescala nos últimos 13 anos, sugerindo que estes eventos estão, em uma média global, ficando mais energéticos. Estas tendências variam regionalmente e a variabilidade espacial é mais pronunciada próximo da extensão para leste das correntes de contorno oeste (CCO), sugerindo um aumento do cisalhamento da velocidade geostrófica. O afastamento das CCO da costa provoca, na região de sua ocorrência, intensa atividade vortical e meandramento, constituindo, do ponto de vista da anomalia da altura da superfície do mar (AASM), as áreas mais energéticas do planeta. O exemplo no Atlântico Sul é a separação da Corrente do Brasil (CB) em sua região de encontro com a Corrente das Malvinas (CM). A CB flui quase-meridionalmente para sul até aproximadamente 36°S, iniciando seu afastamento da costa até 38°S devido ao encontro de suas águas quentes e salinas com as águas de origem subpolar da CM, conforme Garzoli & Garrafo (1989). Essa região recebe o nome de Confluência Brasil-Malvinas (CBM).

Remarks on the morphology and distribution of some rare centric diatoms in southern Brazilian continental shelf and slope waters

This paper provides information on the morphology and occurrence of extant diatoms of the family Asterolampraceae and Azpeitia species of the southernmost Brazilian continental shelf and slope waters in the Southwestern Atlantic Ocean (28 - 34°S), under the influence of Tropical, Subtropical, Subantarctic Waters, terrestrial discharges from La Plata River and Lagoa dos Patos lagoon. Plankton was sampled (20 µm net; vertical hauls) at the same 27 stations in winter 2005 and summer 2007. Among Asterolampraceae, Asteromphalus flabellatus was the most frequent species (57% of samples) observed mainly in winter samples (92%) in Subtropical Shelf Water but also under the influence of La Plata River plume (salinity <35). Lower frequencies were observed for Asterolampra marylandica, Asteromphalus elegans, Asteromphalus heptactis and Spatangidium arachne. Four species of Azpeitia were observed: A. barronii and A. neocrenulata for the first time in the South Atlantic Ocean while A. africana and A. nodulifer had already been registered in equatorial and southern areas of Brazil. All Azpeitia species were rare (19%) in offshore samples (100-200 m depth. Remarks on the morphology based on light and scanning electron microcopy observations are provided along with their distribution in the study area.

Utilização de pescado na elaboração de produto destinado à merenda escolar

O pescado é considerado um alimento de grande valor nutricional presente na dieta, devido a sua elevada qualidade proteica. O consumo desta importante fonte proteica ainda não faz parte da rotina da população brasileira. Para tanto, o governo busca alternativas para mudança desta realidade. O desenvolvimento e introdução de produtos a base de pescado na merenda escolar vem sendo indicados como uma solução estratégica para inserir este alimento na dieta da população. Nesse sentido, este trabalho teve por objetivo elaborar produto a base de anchoita (Engraulis anchoita) e verificar sua aceitação junto à rede pública de ensino, visando um futuro aumento do consumo de pescado. A matériaprima utilizada foi à espécie anchoita (Engraulis anchoita), capturada através de cruzeiros realizados pelo navio oceanográfico Atlântico Sul, da Universidade Federal do Rio Grande (FURG). O desenvolvimento do trabalho gerou três artigos. O primeiro artigo intitulou-se “Elaboração de almôndegas utilizando como matéria-prima anchoita (Engraulis anchoita)”. O objetivo do trabalho foi formular almôndegas à base de carne de pescado (Engraulis anchoita) e caracteriza-las quanto à composição proximal e aminoacídica. Foi verificado que em torno de 160 gramas do produto elaborado atende às necessidades aminoacídicas estipuladas pela FAO, para um adulto. Os resultados indicaram que o produto elaborado está de acordo com padrão de identidade estabelecido pela legislação brasileira. No segundo artigo “Capacitação de merendeiras na elaboração de produtos de pescado” o objetivo foi promover a capacitação de merendeiras na elaboração de produtos de pescado. Uma análise sobre comportamento, intenção do comportamento e atitude frente ao consumo de pescado, foi realizada. Além disso, também foi realizada uma avaliação sobre a percepção cognitiva das merendeiras em relação a segurança alimentar, antes e após o treinamento. Com relação ao comportamento, os resultados demonstraram que a população estudada apresentou a intenção de comer pescado, no entanto, não apresentou o comportamento de consumo. Os resultados de avaliação cognitiva e segurança alimentar demonstraram que o desenvolvimento do curso foi satisfatório, uma vez que novas percepções e conhecimentos sobre segurança alimentar foram adquiridos pelas merendeiras. O terceiro artigo “Respostas hedônicas e associação de palavras para melhor compreensão da aceitação de produtos de pescado na merenda escolar” teve como objetivo avaliar a aceitação de almôndega de pescado (Engraulis anchoita) junto à merenda escolar de uma escola da rede pública de ensino. Os resultados demonstraram que a idade e aceitação obedecem a uma relação inversa na aceitação de produtos de pescado. A avaliação cognitiva possibilitou identificar que as percepções que melhor explicam a aceitação das almôndegas de pescado pelos escolares estão relacionadas com os atributos hedônicos e sensoriais do produto. Em suma, o desenvolvimento dessa dissertação demonstrou que a elaboração de almôndegas de pescado (Engraulis anchoita) destinadas à merenda escolar surge como uma importante ferramenta para impulsionar a inserção do pescado na merenda escolar e contribuir para uma educação alimentar quanto ao consumo de pescado.
