A obra de Raymundo Faoro é examinada da perspectiva da sua atualidade e no confronto com os seus críticos. Diversamente de Sérgio Buarque de Holanda, o projeto de Faoro é "civilizador": recusa as soluções que implicam a retomada das origens e enfrenta a alternativa entre civilização e barbárie na busca do "Outro".

A questão ética é central nos escritos de Raymundo Faoro, argumenta a autora, para quem a obra de Faoro, desde o seu clássico Os Donos do Poder há 40 anos, exibe de ponta a ponta sua qualidade de educador político.

A autora aborda a Violência a partir de uma perspectiva ''personalista e fenomenológica'', para que não fique restrita ao seu sentido usual, de violação da integridade física. O artigo toma as filosofias de M. Buber e T. Adorno como plataforma da reflexão, ambas preocupadas em estabelecer uma ''fenomenologia dos sentidos'', e compara suas conseqüências éticas, mostrando como um compreensão ampliada da Violência emerge desse ponto de vista.

The Pantanal is a Quaternary sedimentary basin located at the left margin of the Upper Paraguay River, west-central Brazil. Basin infilling was mainly by siliciclastic sediments and the stratigraphic succession exhibits an overall finingupward pattern. The depositional system tract is composed by a large meandering fluvial plain and several marginal alluvial fans, being the Taquari megafan the most striking feature. The present landscape is a complex tropical wetland, with geomorphic features derived from the present conditions and other inherited from successive Pleistocene and Holocene climates. During the Pleistocene, the sedimentary environment was dominated by braided alluvial fans, the original geometry of which is preserved as relict forms, permitting remarkable patterns of distributary paleochannels to be easily recognized in satellite images. Eolian processes were active in some abandoned lobes, contemporaneously with sedimentation in active fan lobes. Closed ponds bordered by lunette sand dunes, originally salt pans produced by eolian deflation, are relict eolian landforms in the Pantanal landscape. Eolian processes were probably more effective at the glacial maximum. Landscape has been changing in the Pantanal area since the end of the Pleistocene in adaptation to a more humid and warmer environment prevailing during Holocene. Initiation of the modern wetland has occurred during the Pleistocene / Holocene transition, with the change to a more humid climate and the individualization of lacustrine systems. The modern Pantanal wetland is a vast expanse of poorly drained lowlands that experiences annual flooding from summer to fall months. Although climatic fluctuations have occurred during all the Holocene, the alluvial fans have remained active depositional systems and lobes were formed by progradation and abandonment. Abandoned lobes were subjected... (Complete abstract click electronic address below)

In this article it is examined the work Persepolis, animation movie which summarizes the four volumes of the homonymous work launched in the form of comics in France, between 2000 and 2003. Narrated by the author Marjane Satrapi, it portraits the 15 years following the events of 1979 in Iran, from her personal perspective. Belonging to a left-wing social group, westernized according to the Iranian standards, she saw its utopias die as the Islamic Revolution won. However, during an auto exile in Vienna in her teen ages, she realized that the vaunted western liberty also charged its price. Considering Persepolis narrative literally as a look into perspective, it is debated the political and social aspects of the relationship east / west in a particular relation with the work of Edward Said.

Os morcegos estão constantemente expostos a condições ambientais que podem alterar o seu padrão de atividade. No presente trabalho descrevemos a atividade horária de morcegos filostomídeos em três áreas florestais no sudeste do Brasil. Também testamos a influência da temperatura ambiente, luminosidade da lua e de diferentes áreas na atividade de Carollia perspicillata. Foram coletados 154 indivíduos pertencentes à família Phyllostomidae, sendo 37,7% deles representados por C. perspicillata (n = 60). Glossophaga soricina, Sturnira lilium e Desmodus rotundus apresentaram um padrão unimodal em sua atividade. Já Anoura caudifer, Chrotopterus auritus e Micronicterys microtis demonstraram uniformidade nas capturas ao longo da noite. C. persprcillata apresentou um padrão bimodal, com picos de atividade no início e final da noite, no entanto a espécie foi ativa durante todo o período. Houve diferença na atividade de C. perspicillata entre as áreas, sendo uniformemente distribuída nas áreas I e III, e unimodal na área II. A temperatura ambiente e a luminosidade do luar não foram fatores decisivos na regulação da atividade de C. perspicillata.

The common vampire bat Desmodus rotundus has as main food source blood of medium and large sizes mammals, but sporadically is observed feeding on birds, causing occasionally excessive bleeding and economic losses. Due to this D. rotundus is one of the most studied species of bats in the Americas. Once known that the lunar clarity might influence the nocturnal activities of the common vampire bats, the present study was carried out to know the behavior and schedules of emergencies and returns of bats to the shelter, its social behavior at the shelter´s entrance, especially of the dominant male, and the size and composition of the colony in different moon phases. The colony was composed by 105 individuals (65 females and 40 males) harboring in a hollow-tree of Farm Edgardia in Botucatu Municipality, State of São Paulo. Through the eight filming sessions, two for each moon phase, it was possible to observe that the distribution of emergences and returns to the shelter thought the night followed a specific pattern for each moon phase. The greatest number of emerging bats occurred in periods in which the moon was not born yet and the largest number of returns just before moon has been reached its maximum level in the sky. Therefore, the time period that bats are staying outside the shelter seems to be directly influenced by lunar light. This factor can influence the social activity of the colony and, in particular, the dominant male, who remains still on tree’s trunk, near the entrance of the shelter with greater frequency during periods of low moon light

O presente trabalho propõe discutir as produções literárias contemporâneas sobre a temática do vampirismo. Este estudo se fundamenta em análises de textos por meio da observação das práticas discursivas que os constituem. Tomando como corpus os romances Crepúsculo e Lua Nova de Stephenie Meyer, as observações partem dos pressupostos teóricos da Semiótica Discursiva e da Análise do Discurso, aos quais são incorporados estudos sobre cultura, sociologia e identidade. Parte-se do princípio de que o discurso é produto da cultura e, desse modo, incorporam-se a ele fatores históricos e sociais. Por essa razão, torna-se importante examinar os elementos dialógicos e intertextuais dos textos anteriormente apontados em relação às outras produções que tratam do mesmo tema e de outros possíveis, encontrados no corpus. Assim, busca-se compreender primordialmente os mecanismos fundamentais que tornam o texto um objeto de comunicação e de significação

O DNA existe por um único motivo – criar mais DNA. Em cada célula do nosso organismo, o filamento estendido de DNA chega a ter cerca de 2 metros. Se você imaginar que em nosso corpo há perto de 10 trilhões de células, você terá uma ideia da enormidade de DNA que nós possuímos. Assim, se todo o seu DNA fosse emendado em um único filamento, seria tão comprido que se estenderia da Terra à Lua, ida e volta, várias vezes. Pudera, você é proprietário de 20 milhões de quilômetros de DNA. Seu corpo, em suma, é uma máquina de produzir DNA e sem ele você não conseguiria viver. Mas o próprio DNA, apesar de ser considerado “a base da vida”, não está vivo. Ao contrário de qualquer outra molécula, ele é, por assim dizer, “inanimado”. Não é reativo e quimicamente inerte. Por essas razões, pode ser recuperado de restos de sangue, de sêmen, ou de pele secos há muito tempo – milhares de anos, até.

On November 26 th, 2005, Rhea, one of Saturn's moons, is found by Cassini spacecraft approximately at 5.105 km from Saturn. Observations in situ reveal that electrons are depleted in the moon's vicinity. However, Rhea is considered massive enough to retain a thin atmosphere. Assumption was that the atmosphere of Rhea was not composed exclusively of gas, its likely contains solid material that can absorb magnetospheric particles. According to Jones et al. (2008), these particles were in a speci c position so that at the moment of observation the electrons could not be detected. In opposition to this idea there is a group, Tiscareno et al. 2010, Cornell University Library, that underwent intensive search for any material that might be orbiting Rhea using Cassini images, however the could not identify any. Second recommendation made by American researchers and other countries, and accepted by the National Board of Research the Cassini Equinox Mission will continue in orbit around Saturn until 2016.The probe will perform several maneuvers with high inclination to delve into the main ring system, and then enter in Saturn's atmosphere and collide with planet. This research is of great importance because until today no rings were found orbiting satellites. The goal of this work is to analyze the orbital evolution of a set of particles around Rhea disturbance of Saturn, J2 e J4 and check results by the numerical simulations and the possibility of a stable ring orbiting Rhea.

In this paper we analyze how the symbols of land and woman are articulated in the lyric from Ana Paula Tavares. Such motifs, applicants at O lago da lua (1999), will take on a structuring in the poetic universe from this Angolan writer, because architect his being in the world at an existential level and political. Paula Tavares gives her voice to express, with defiance and tenderness, the bitter cry of women prisoners in their own silence. The symbiosis between land and woman works as formative and empowering element of identity

This article suggests the need for change in focus of studies on new instances of participation in public policy management, which emerged in the Brazilian re-democratization. Moving away from the literature that addresses the role of civil society in these instances, the author reviews studies on Participatory Budgeting (PB) indicating how such experiences are marked by the dynamics of political society. The argument is reinforced by the presentation of a survey of PB counselors in Osasco-SP, by which we perceive, in general, a role filled by political processes of representative democracy. Most councilors compose the fringes of the political society, lie on the rise in, seeking better position in the local political field, internal disputes within the parties and the municipal government. This points the limits of the democratizing potential of the PB, since the expansion of participation in budget decisions would be just within the political society.
