No full textO autor analisou a microflora de três tanques situados no Cactário do Jardim Botânico, Rio de Janeiro, Guanabara. Tanque nº 1. Apresentou desenvolvimento muito intenso da microfibra nos mseses mais frios. As diatomáceas foram muito freqüentes. As espécies indicadoras de saprobidade foram as seguintes: Gomphonema gracile Ehr., pinnularia maior. (kutz) Cleve, Gomphonema parvulum (kutz) Grunow, Navicula mutica Kutz., Pinnularia borealis Ehr., Pinnularia microstauron (Ehr) Cleve, Pinnularia acrospheria Breb., Hantzschia amphioxys (Ehr) Grunow, Nitzschia palea Kutz., Eutonia pectinalis (Kutz) Rabenh. Tanque nº 2. As diatomáceas indicadoras de águas contaminadas, anotamos como segue: Eutonia pectinalis (Kutz) Rabenh., Gomphonema parvulum (kutz) Grunow, Hanstzschia amphioxys (Ehr) Grunow, Navicula mutica Kutz, Pinnularia borealis Ehr., Pinnularia maior (Kutz) Cleve, Pinnularia microstauron (Ehr) Cleve. Tanque nº 3. Foi bastante reduzida a freqüência da microflora. Comparando-o com os tanques nº 1 e 2, as diatomáceas e clorofícias observadas, mostraram-se diminuídas nos meses mais quentes. Encontramos as seguintes espécies oligosaprobias: Eunotia pectinalis (Kutz) Rabenh., Gomphonema gracile ehr., Gomphonema parvulum (Kutz) Grunow Hantzschia amphioxys (Ehr) Grunow, Pinnularia borealis Ehr., Pinnularia maior (Kutz) Cleve. Foram consideradas também as clorofíceas quanto ao regime de saprobidade do material estudado. Eutonia augusta f. crenulata Cleve-Euler e Eutonia veneris var. exsecta Clever-Euler encontradas em nossas amostras, são novas para o Brasil. Um total de 71 espécies foram determinadas de 21 coletas realizadas durante o período de 36 meses.The author analysed the microflorafrom three ponds situated in the Cactarium from the Botanical Garden of Rio de Janeiro, Guanabara. Pond nº 1 - This pond showed a very intensive development of the microflora in the coldermonths. The diatoms were very frequent. Those diatoms that indicate saprobic conditions were the following; Gomphonema gracile Ehr., Pinnularia maior (Kutz) Cleve, Gomphonema parvulum (Kutz) Grunow, Navicula mutica Kutz., Pinnularia borealis Ehr., Pinnularia microstauron, (Ehr) Cleve, Pinnularia acrospheria Breb., Hantzschia amphioxys (Ehr) Grunow, Nitzschia palea Kutz., Eunotia pectinalis (Kutz) Rabenh. Pond nº 2 - In this pond we found diatoms that indicate polluted waters as follows; Eunotia pectinalis (Kutz) Rabenh., Gomphonema parvulum (Kutz) Grunow, Hantzschia amphioxys (Ehr) Navicula mutica Kutz., Pinnularia borealis Ehr., Pinnularia maior (Kutz) Cleve, Pinnularia microstauron (Ehr) Cleve. Pond nº 3 - The frequence of the microflora was rather reduced. Comparing the pond nº 1 with the one nº 2, the diatoms and chlorophyceae decreased in the hotter months. The oligosaprobic species found were the fallowing: Eutonia pectinalis (Kutz) Rabenh., Gomphonema gracile Ehr., Gomphonema parvulum (Kutz) Grunow, Hantzschia amphoxys (Ehr) Grunow, Pinnularia borealis Ehr., Pinnularia maior (Kutz) Cleve. Considerations were also made to the chlorophyceae as to saprobic regimen of the material estudied. Reference is made in the text to ecological details and comments. Eunotia angusta f. crenulata Elever-Euler and Eunotia veneris var. exsecta Clever-euler, that we found in our samples are new to Brazil. A total of 71 species was determined from 21 samples collected during the period of 36 months
Cinema in the literature of Caio Fernando Abreu: cinematographic procedures in Morangos mofados
No full textEsse projeto se propõe a investigar e discutir quais procedimentos cinematográficos foram utilizados para compor a escrita da obra Morangos mofados, de Caio Fernando Abreu. De que forma a experiência do cinema impacta a poética do escritor cinéfilo? A partir da análise da presença de filmes e trilha sonora referenciados por Abreu em seus contos e correspondência, pretende-se entender a qual tradição narrativa, clássica ou contemporânea, ele se filia. Para tanto, a presente leitura convoca as seguinte obras sobre roteirização fílmica para compreender o modo de narrar do autor: A literatura através do cinema: realismo, magia e a arte da adaptação, de Robert Stam, e Culturas Narrativas Dominantes: O caso do Cinema, de João Maria Mendes. Como resultado, espera-se contribuir para os estudos comparados que se dedicam às relações entre literatura e cinemaThis project’s purpose is to investigate and discuss which cinematographic procedures were used to compose the writing of Morangos mofados (1982) by Caio Fernando Abreu. In which way the experience of cinema impacts the poetics of the cinephile writer? Through the analysis of presence of movies and soundtracks referenced by Abreu in his tales and mail, our intent is to understand to which narrative tradition, classic or contemporary, he affiliates himself. To that end, the present reading evokes the following pieces on screenwriting in order to comprehend the way of narrating celebrated by the author: Literature through Cinema: Realism, magic and the art of adaptation, by Robert Stam, and Dominant Narrative Cultures: the case of cinema, by Joao Maria Mendes. As a result, one hopes to contribute to the comparative studies that dedicate themselves to relationships between literature and cinemaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior – CAPE
Distribuição geográfica da fauna e flora da Baía de Guanabara Geographic distribution of the flora and the fauna of the Guanabara Bay
No full textThe author studied, the horizontal and vertical distribution of most common part of the flora and fauna of the bay of Guanabara at Rio de Janeiro. In this paper the eulittoral, poly, meso and oligohaline regions were localised and studied; and the first chart of its distribution was presented (fig. 2). The salinity of superficial waters was established through determinations based on 30 trips inside the buy for collecting biological materials. Some often 409 determinations which were previous reported together with the present ones served for the eleboration of a salinity map of the bay of Guanabara (fig. 1). This map of fig. 2 shows the geographic locations of the water regions. EULITTORAL WATER REGIME — Fig. 3 shows the diagram scheme of fauna and flora of this regime. Sea water salinity 34/1.000, density mean 1.027, transparent greenish waters, sea coast with moderate bursting waves. Limpid sea shore with white sand, gneiss with the big barnacle Tetraclita squamosa var. stalactifera (Lam. Pilsbry. Vertical distributions: barna¬cles layers with a green region in which are present the oyster Ostrea pa-rasitica L., the barnacles Tetraclita, Chthamalus, Balanus tintinnabulum var. tintinnabulum (L.) e var. antillensis Pilsbry in connection with several mollusca and the sea beatle Isopoda Lygia sp. Covered by water and exposed to air by the tidal ritms, there is a stratum of brown animals that is the layer of mussels Mytilus perna L., with others brown and chestnut animals : the Crustacea Pachygrapsus, the little crab Porcellana sp., the stone crab Me-nippe nodifrons Stimpson, the sea stars Echinaster brasiliensis (Mull. & Tr.), Astropecten sp. and the sea anemones Actinia sp. Underneath and never visible there is a subtidal region with green tubular algae of genus Codium and amidst its bunches the sea urchin Lycthchinus variegatus (Agass.) walks and more deeply there are numerous sand-dollars Encope emarginata (Leske). The microplancton of this regime is Ceratiumplancton. POLYHALINE WATER REGIMB — Water almost sea water, but directly influenced by continental lands, with rock salts dissolved and in suspension. Salinity: 33 to 32/1.000. This waters endure the actions of the popular nicknamed «water of the hill» (as the waters of mesohaline and oligohaline regimes), becoming suddenly reddish during several hours. That pheno¬menon returns several times in the year and come with great mortality of fishes. In these waters, according to Dr. J. G. FARIA there are species of Protozoa : Peridinea, the Glenoidinium trochoideum St., followed by its satellites which he thinks that they are able to secret toxical substances which can slaughter some species of fishes. In these «waters of the hill» was found a species of Copepoda the Charlesia darwini. In August 1946 the west shore of the Guanabara was plenty of killed fishes occupying a area of 8 feet large by 3 nautical miles of lenght. The enclosure for catching fishes in the rivers mouthes presents in these periods mass dead fishes. The phenomenon of «waters of the hill» appears with the first rains after a period of long dryness. MESOHALINE WATER REGIME — Fig. 4 shows the the diagramm scheme. Salt or brackish water from 30 to 17/1.000 salinity, sometimes until 10/1.000. Turbid waters with mud in suspension, chestnut, claveyous waters; shore dirty black mud without waving bursting; the waters are warmer and shorner than those of the polihaline regime. Mangrove shore with the mangrove trees : Rhizophora mangle L., Avicennia sp., Laguncularia sp., and the »cotton tree of sea» Hibiscus sp. Fauna: the great land crab «guaimú» Cardisoma guanhumi Latr., ashore in dry firm land. There is the real land crab Ucides cordatus (L.) in wetting mud and in neigh¬ bourhood of the burrows of the fiddler-crabs of genus Uca. On stones and in the roots of the Rhizophora inhabits the brightly colored mangrove-tree-crab («aratu» Portuguese nickname) Goniopsis cruentata (Latreille) and the sparingly the big oyster Ostrea rhizophorae Guild. Lower is the region of barnacles Balanus amphitrite var. communis Darwin and var. niveus Darwin; Balanus tintinnabulum var. tintinnabulum (L.) doesn't grow in this brackish water; lower is the region of Pelecipoda with prepollency of Venus and Cytherea shell-fishes and the Panopeus mud crab; there are the sea lettuce Ulva and the Gastreropod Cerithium. The Paguridae Clibanarius which lives in the empty shells of Gasteropod molluscs, and the sessile ascidians Tethium plicatum (Lesuer) appears in some seasons. In the bottom there is a black argillous mud where the «one landed shrimps» Alpheus sp. is hidden. OLIGOHALINE WATER REGIME — The salinity is lower than 10/1.000. average 8/1.000. There are no barnacles and no sea-beetles Isopods of genus Lygia; on the hay of the shore there are several graminea. This brackish water pervades by mouthes of rivers and penetrates until about 3 kilometers river above. While there is some salt dissolved in water, there are some mud crabs of the genus Uca, Sesarma, Metasesarma and Chasmagnatus. The presence of floating green plants coming from the rivers in the waters of a region indicated the oligohaline waters, with low salt content because when the average of NaCl increases above 8/1.000 these plants die and become rusty colored

A Meditação de Gonçalves Dias. A natureza dos males brasileiros
No full textThis article makes a critical reading of Meditação, the work in poetic prose by Maranhão-born poet Gonçalves Dias, published piecemeal in the magazine O Guanabara in the early 1850s. Meditação was relegated by the critics, who concentrated on Gonçalves Dias\u27 poetic production and, to a lesser extent, on his ethnographic production. It is a text in which the author is eloquently critical, in a counter-ideological movement remarkable at the time.Este artigo tem o intuito de realizar uma leitura crítica da obra em prosa poética Meditação, do poeta maranhense Gonçalves Dias. Dita obra, publicada fragmentariamente na revista O Guanabara no começo da década de 1850, foi relegada pela crítica especializada, concentrada, geralmente, na produção poética de Gonçalves Dias e, em menor medida, na produção etnográfica. Trata-se de um texto no qual o autor exerce a crítica de forma eloquente, num movimento contraideológico notável para a época
Aço ABNT 1045 esferoidizado: estudo da cinética de coalescimento e correlações entre microestruturas e propriedades mecânicas
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Ciência e Engenharia de MateriaisEste trabalho teve por objetivo estudar o processo de recozimento de esferoidização de um aço SAE 1045 e correlacionar as suas propriedades mecânicas com as respectivas microestruturas apresentadas. As amostras foram laminadas à frio (com 21% de deformação) e também temperadas (austenitizadas em 850ºC, 1000ºC e 1100ºC por 30 minutos e resfriadas em água), de modo a obter diferentes microestruturas, prévias ao recozimento de esferoidização. Para o estudo do efeito das variações dos tratamentos térmicos na esferoidização foram utilizados dois ciclos térmicos: um subcrítico, logo abaixo de Ac1 (710ºC por 18 e 22 horas) e outro pendular, em torno de Ac1 (entre 740ºC e 680ºC) por 22 horas. Estas variações no processo de preparação das amostras, objetivaram ampliar as diferenças entre os parâmetros a serem avaliados, de modo a melhor correlacioná-los com as propriedades mecânicas obtidas. Análises qualitativas e quantitativas foram realizadas via microscopia ótica e eletrônica de varredura. O comportamento mecânico foi avaliado a partir de ensaios de tração e de dureza das amostras esferoidizadas. Variações na distribuição e forma dos carbonetos, bem como, do tamanho de grão ferrítico, influenciaram de forma direta as propriedades do aço esferoidizado, indicando uma maior dependência das propriedades mecânicas sobre os carbonetos, que do tamanho de grão ferrítico. A cinética de esferoidização também foi estudada, visando fornecer informações referente ao comportamento do aço SAE 1045 frente a duas microestruturas prévias, uma deformada e outra temperada. Boas correlações foram obtidas após a análise dos resultados apresentados

Primeira contribuição ao conhecimento da tribu Cuphoceratini: (Diptera, Tachinidae)
No full textThe author studies 10 species of the Tribu Cuphoceratini, belonging to the genera Ccrpecrypta Townsend, 1908, Cyanopsis Townsend, 1917, Spanipalpus Townsend, 1931, Neocuphocera Townsend, 1927, Beskiocephala Townsend, 1916 and Deopalpus Townsend, 1908. Eight species are identified with previously described species and two species are considered new to science: Neocuphocera aurifacies sp. n. and Deopalpus reinhardi sp. n. The characteristics of the new species are chiefly founded in the male genitalia. Generic definitions are based on the following characters: presence or absence of ocellar bristles, shape and relative length of antennal articles and arrangement of the head bristles in both sexes. The material is located in the Institute Oswaldo Cruz collections, Guanabara, Brazil
