The aim of this paper is to discuss the presence of epic and ancient romance as construction’s mechanism of the poem Galáxias by Haroldo de Campos, whose work was, all of the time, dedicated to both: innovation in poetry forms and rescue of tradition. It is quite important to investigate how epic and ancient narrative elements contribute to the meaning construction of poem Galaxias, written by Campos during thirteen years. This investigation appears to be very challenging because seems to be an opportunity to think about post-modern and post-antique, at the same time, making both instances dialogue. Galáxias seems to be exemplary to show this dialogue between present and past: it is a sea voyage book and a book as sea voyage, not only because the epic and ancient narrative have strong presence in the poem, but also because the poem central theme is the sea voyages – and the book.

O pescado e seus derivados têm uma grande importância na dieta, em todo o mundo. Sabe-se que peixes e frutos do mar fortalecem o sistema imunológico, contribuem para a redução dos níveis de colesterol, diminuem as chances de depressão, ajudam na formação dos músculos e protegem contra doenças cardiovasculares. Também, são ricos em vitaminas lipossolúveis A, D e E, além do ômega 3. Muitas vezes, esses produtos são consumidos crus ou com pouco preparo e com isso faz-se necessário medidas higiênico- sanitárias, pois podem ser contaminados com micro-organismos causadores de doenças. A análise microbiológica dos alimentos para se verificar a presença de micro-organismos prejudiciais é fundamental para se conhecer as condições de higiene nas quais estes alimentos foram preparados. Assim, 80 amostras de peixes e frutos do mar de peixarias e supermercados de Botucatu, SP, foram analisadas com o objetivo de verificar se esses alimentos estão dentro dos padrões estabelecidos pela legislação brasileira, através da RDC nº12, através da detecção da presença de Salmonella sp., Staphylococcus aureus e determinação do número mais provável de coliformes termotolerantes (CT), mesmo que este último não faça parte dos parâmetros para esse alimento, mas foi pesquisado para avaliação de suas condições higiênicas. Cada amostra (25 gramas) foi homogeneizada em 225ml de água peptonada e para a detecção de S. aureus, utilizou-se método spread Baird Parker, seguida de catalase, coagulase e kit Dry Spot. Para a detecção de Salmonella, utilizou-se caldo tetrationato (35ºC/24h) e Rapapport (42ºC/24h), semeados em ágar SS e XLD. As colônias foram testadas em TSI, ágar fenilalanina e testadas em poli soros somático e flagelar. Quanto aos CT, empregou-se a técnica de tubos múltiplos, inoculando diluições da amostra em caldo Lauril sulfato, na fase presuntiva e depois em caldo EC (45ºC) na fase confirmatória. De ...

Nutrient distributions observed at some depths along the continental shelf from 27 degrees 05`S (Brazil) to 39 degrees 31`S (Argentina) in winter, 2003 and summer, 2004 related to salinity and dissolved oxygen (mL L-1) and saturation (%) data showed remarkable influences of fresh water discharge over the coastal region and in front of the La Plata estuary. In the southern portion of the study area different processes were verified. Upwelling processes caused by ocean dynamics typical of shelf break areas, eddies related to surface dynamics and regeneration processes confirmed by the increase of nutrients and the decrease of dissolved and saturation oxygen data were verified. High silicate concentrations in the surface waters were identified related to low salinities (minimum of 21.22 in winter and 21.96 in summer), confirming the importance of freshwater inputs in this region, especially in winter. Silicate concentration range showed values between 0.00 and 83.52 mu M during winter and from 0.00 to 41.16 mu M during summer. Phosphate concentrations worked as a secondary trace of terrestrial input and their values varied from 0.00 to 3.30 mu M in winter and from 0.03 to 2.26 mu M in summer; however, in shallow waters, phosphate indicated more clearly the fresh water influence. The most important information given by nitrate concentrations was the presence of water from SACW upwelling that represents a new source of nutrients for marine primary production. Nitrate maximum values reached 41.96 M in winter and 33.10 mu M in summer. At a depth similar to 800m, high nitrate, phosphate and silicate concentrations were related to Malvinas Current Waters, Subantarctic Shallow Waters and Antarctic Atlantic Intermediate Waters (AAIW). Dissolved oxygen varied from 3.41 to 7.06 mL L-1 in winter and from 2.65 to 6.85 mL L-1 in summer. The percentage of dissolved oxygen saturation in the waters showed values between 48% and 113% in winter and from 46% to 135% in summer. The most important primary production was verified in the summer, and situations of undersaturation were mainly observed below 50 m depth and at some points near the coast. The anti-correlation between nutrients and dissolved oxygen which showed evident undersaturation also revealed important potential sites of remineralization processes. The nutrient behaviours showed some aspects of the processes that occur over the Southwestern South Atlantic continental shelf and in their land-sea interfaces between Mar del Plata and Itajai.

Two new records of Anopheles homunculus in the eastern part of the Atlantic Forest are reported. This species was found for the first time in Barra do Ouro district, Maquine municipality, Rio Grande do Sul state, located in the southern limit of the Atlantic Forest. The 2nd new record was in the Serra Bonita Reserve, Camacan municipality, southeast Bahia state. These records extend the geographical distribution of An. homunculus, suggesting that the species may be widely distributed in coastal areas of the Atlantic Forest. It is hypothesized that the disjunct distribution of the species may be caused by inadequate sampling, and also difficulties in species identification based only on female external characteristics. Species identification was based on morphological characters of the male, larva, and pupa, and corroborated by DNA sequence analyses, employing data from both 2nd internal transcribed spacer of nuclear ribosomal DNA and of mitochondrial cytochrome c oxidase subunit I.
