Das estantes para a tela: práticas de leitores de livros impressos e digitais do curso de Comunicação Social da Universidade Federal do Rio Grande do Norte

La cultura del libro impreso impregna la vida cotidiana de los lectores durante más de cinco siglos, y de esto, hábitos y significados a cerca del libro como medio de comunicación tienen sus raíces en la comunidad lectora, en una especie de contrato de lectura (VERÓN, 2004). Por lo tanto, creemos que es posible conjeturar que la aparición del libro digital puede cambiar las viejas prácticas en relación con el libro impreso y por eso mismo deben ser investigadas con el fin de entender este tiempo de productos reconfigurados. Consciente de ello, el tema central de nuestra investigación se basa en la comprensión de cómo los lectores de libros digitales realizan sus prácticas. Nuestro objetivo general es investigar las prácticas socioculturales de los lectores de libros digitales, con el fin de mostrar las continuidades y discontinuidades en el uso del libro en su formato impreso y digital. Con este fin, se busca 1) proponer una caracterización de la cultura del libro impreso, que es el apoyo a una asignación posible de las marcas de una cultura del libro digital, y 2) explorar los lugares de producción y oferta de los libros digitales, especialmente en Brasil, fin de delimitar en su primera configuración. Apoyamos, como propuesta metodológica, la sistematización de dimensiones culturales del libro impreso llamadas: ritualidad, simbología, materialidad y forma, lo que ayudará el enfoque del empírico. Nuestra propuesta se basa, en varios puntos, en los investigadores de la historia del libro, insertada en el campo de la Historia Cultural (BURKE, 2008; CHARTIER, 1992, 1994, 2006; DARNTON, 1990, 2006, 2010). Adoptamos como técnica de investigación el análisis de voces, registradas a través de entrevistas en profundidad, de lectores de libros en formato digital. Antes de eso, creemos apropiado emprender un estudio exploratorio basado en la aplicación de un cuestionario online. Nuestra delimitación incluye lectores de libros digitales del curso de Comunicación Social de la Universidad Federal de Rio Grande do Norte. Entre las conclusiones de esta disertación, es posible señalar que el grupo de lectores investigados está sólidamente ligado a las experiencias con los libros impresos y esto afecta en gran medida las prácticas de los libros digitales

Estratégia de vida do peixe anual Hypsolebias antenori (Cyprinodontiformes: Rivulidae) do semiárido brasileiro

This work deals with the life strategy of an endangered annual fish, Hypsolebias antenori (Cyprinodontiformes: Rivulidae), of the Brazilian semiarid region. The eggs of these fish hatch at the onset of the rainy season, grows rapidly and they reproduce during the rainy season. When the water puddles dry out, the entire population dies. The resistant eggs which are buried in the bottom of the dried pools go through diapause stages, during which time the embryonic development becomes temporarily arrested. With the onset of the next rainy season, the eggs hatch and a new generation is formed. Specimens of H. antenori were captured during 2011 and 2013, in temporary water pools located in the hydrographic basin of river Jaguaribe in Ceará, Brazil. Sex ratio, the length-weight relationship, the growth type, first sexual maturity, anatomy and histology of the digestive tract, development of gonads, reproductive strategy, karyotypic pattern of the species, and the conservation status of H. antenori were investigated. The results of this study are presented in the form of eight articles. The first article is about the fish faunal composition of the hydrographic basins of Rio Grande do Norte, Brazil, wherein the record of H. antenori is included. The second article deals with the sex ratio, secondary sexual characteristics of males, the length-weight relationship and the type of growth. Males show a pattern of intense coloration with well developed fins. The sex ratio showed a significant predominance of females (1M:1.7 F). Males were larger in length and weight. The equation of weight and total length relationship was Wt=0.0271Lt3,8937, showing a positively allometric growth, indicating greater increase in weight than in length. The third article discusses the anatomy and histology of the digestive tract of H. antenori. It is considered as a generalist feeder with characteristics of omnivore, which utilizes different food sources. The fourth article discusses the stages and phases of gonad development and type of spawning of H. antenori. The fifth article is about the r reproductive strategy adopted by H. antenori which helps in successful reproduction over a short period of life. The sixth article deals karyotypic pattern of the species, constituting the first cytogenetic contribution to the genus. The seventh article discusses about the risk of extinction of this species which suffers a series of threats, such as, habitat loss through land use, deforestation, construction of reservoirs, pollution due to domestic and industrial sewage, besides pesticides and agrochemicals. Furthermore, decreasing rainfall and intensification of aridity due to global climate changes, interferes with the reproductive cycle. The eighth article deals with aggressive behavior adopted between males and among females during reproduction. All temporary water pools sampled during this study were in high degree of degradation, mainly due to human action. There is a great need for conservation measures to protect the populations of annual fish, including the creation of protected areas in the semiarid ephemeral aquatic environments of Brazil

O graben de Palestina: contribuição à estratigrafia e estrutura do estágio rifte na bacia do Araripe, nordeste do Brasil

The Palestina Graben is one of the NE-trending asymmetric grabens of the Araripe Basin. This basin rests on the precambrian terrains of the Transversal Zone, Borborema Province, immediately to the south of the Patos Lineament. It is part of the Interior Basins province of Northeastern Brazil, being related to the fragmentation of the Gondwana supercontinent and the opening of the South Atlantic ocean. The Palestina Graben trends NE-SW and presents an asymmetric geometry, controled by the NW extensional eocretaceous strain. The graben borders display distinct geometries. The SE border is a flexural margin, characterized by the non conformity of the eopaleozoic Mauriti Formation (the oldest unit of the basin) overlying the crystalline basement, but also affected by normal faults with small displacements. On the opposite, the NW border is continuous and rectilinear, being marked by normal faults with major displacements, that control the general tilting of the layers to the NW. In this sense, the Mauriti Formation is overlain by the Brejo Santo, Missão Velha (which also occurs in the Brejo Santo-Mauriti horst, to the NW of the fault border) and Abaiara formations, the latter restricted to the graben. The interpretation of available gravity data and a seismic line indicates that the main fault has a variable dip slip component, defining two deeper portions within the graben, in which the sedimentary column can reach thicknesses of up to 2 km. Regarding to the stratigraphy of Araripe Basin in the study area, the sedimentary package includes three distinct tectonosequences. The Paleozoic Syneclisis Tectonosequence is composed by the Mauriti Formation, deposited by a braided fluvial system. The Jurassic Tectonosequence, whose tectonic setting is still debatable (initial stage of the Neocomian rift, or a pre-rift syneclisis ?), is represented by the Brejo Santo Formation, originated in a distal floodplain related to ephemeral drainages. The Rift Tectonosequence, of neocomian age, includes the Missão Velha Formation, whose lower section is related to a braided to meandering fluvial system, outlining the Rift Initiation Tectonic Systems Tract. The upper section of the Missão Velha Formation is separated from the latter by a major unconformity. This interval was originated by a braided fluvial system, overlain by the Abaiara Formation, a deltaic system fed by a meandering fluvial system. Both sections correspond to the Rift Climax Tectonic Systems Tract. In the area, NE-trending normal to oblique faults are associated with NW transfer faults, while ENE to E-W faults display dominant strike slip kinematics. Both NE and E-W fault sets exhibit clear heritage from the basement structures (in particular, shear zones), which must have been reactivated during the eocretaceous rifting. Faults with EW trends display a dominant sinistral shear sense, commonly found along reactivated segments of the Patos Lineament and satellyte structures. Usually subordinate, dextral directional movements, occur in faults striking NNW to NE. Within this framework bearing to the Palestina Graben, classical models with orthogonal extension or pull-apart style deserve some caution in their application. The Palestina Graben is not limited, in its extremeties, by E-W transcurrent zones (as it should be in the case of the pull-apart geometry), suggesting a model close to the classic style of orthogonal opening. At the same time, others, adjacent depocenters (like the Abaiara-Jenipapeiro semi-graben) display a transtensional style. The control by the basement structures explains such differences

A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais

The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed parallel to the coast, combined with coast engineering interventions. High energy hydrodynamic process are responsible for the morphological instability of the coast. The study was based on remote sensing data obtained between 1954 and 2007 which consist in orbital images from Landsat, CBERS and Ikonos satellites and aerial photos. With all data integrated on GIS environment it was possible to update thematic maps of geology, geomorphology, vegetation, soil and landuse and development of multitemporal maps pointing areas with erosion and depositions of sediments, defining the critical erosion process on this region. The bigger morphological changes are related to changes on wind patterns during the year, terrestrial and sea breezes during the day, with spits and barrier island migration, opening and closing of channels like the one parallel to the coast on the area of Serra and Macau oil fields. These factors combined with the significant reduction on sediment budgets due to the loss of natural spaces to sediment reworking contribute to the low resilience which tends to be growing on the area of Serra and Macau oil fields. In front of such scenery a detailed monitoring was done in order to find technological possibilities for coastal restoration. A pilot area was defined to start the project of mangrove restore together with beach nourishment in order to minimize the effect of the erosion caused by the channel parallel to the coast, contributing to stabilize the northeast channel as the main one. It s expected that such methodology will aid the coastal environments restoration and the balance between industrial activities and coastal erosion

Comportamento de oviposturas individuais, percentagem de eclosão e peso larval mínimo para pupação em populações de Chrysomya megacephala (F.)

Chrysomya megacephala (F.), a exemplo de muitas outras moscas-varejeiras, utiliza recursos discretos e efêmeros para alimentação e oviposição, tais como carcaças em decomposição. O contexto espacial em que ocorre competição por alimento em C. megacephala caracteriza-se por duas populações: indivíduos adultos dispersando-se e imaturos que são depositados nos substratos pelas fêmeas adultas. O objetivo do estudo foi investigar aspectos da bionomia associados com competição larval por alimento em populações experimentais de C. megacephala, incluindo comportamento de ovipostura e peso mínimo necessário para pupação. Os resultados indicaram que fêmeas depositam parte de seus ovos produzidos, contrastando com estudos anteriores que consideraram apenas ovipostura completa. A percentagem de eclosão de larvas foi alta (90 %) e o peso mínimo necessário para pupação situou-se entre 30 e 32 mg.
