Abstract: The paper examine the meaning and relevance of Hannah Arendt's distinction between world and life, demonstrating how these fundamental dimensions of the human condition throughout modernity reached a dangerous zone of irreducible indistinction that has diluted the demarcation between the worldly context of human existence and the space of biological life. It is intended, therefore, consider the biopolitical implications of this lack of distinction between the world and life, in order to develop a critical examination of the limits and impossibilities of politics in the contemporary scene.

Abstract: The objective of this article is to analyze the ontological-existential meaning of science in Heidegger’s works. It makes an investigation in the complex relation between philosophy and science through the topic of the limits of science in Heidegger’s concept of transcendence.
La acción política como base fenoménica de la libertad en Hannah Arendt
Rodrigo Ribeiro Alves Neto
Revista Observaciones Filosóficas , 2011,
Abstract: This article presents the fundamental elements of Hannah Arendt's reflection on the political action as a base the original phenomenal freedom, seeking to show how the relevance of this politicization of freedom or this coincidence between freedom and action resides in task of recovering its public meaning, as opposed to the conceptions that promoted a divorce between freedom and politics.

Abstract: thymidine analogs have been labeled with different radioisotopes due to their potential in monitoring the uncontrollable cell proliferation. considering that the radioisotope technetium-99m still keeps a privileged position as a marker due to its chemical and nuclear properties, this work was designed to develop a new technique of labeling of thymidine analog with 99mtc, by means of the organometallic compounds. the aims of this research were: synthesis of the organometallic precursor technetium-99m-carbonyl, thymidine labeling with this precursor, study of stability, and radiochemical e biological evaluation with healthy and tumor-bearing animals. the organometallic precursor and the labeling of thymidine with this precursor were resulted with a radiochemical pureness of > 97% and > 94%, respectively, with good radiochemical stability up to 6 h in room temperature. the cysteine and histidine challenge indicated losses between 8 and 11% for concentrations until 300 mm. the biodistribution assay in healthy mice revealed rapid blood clearance and low uptake by general organs with renal and hepatobiliary excretion. the tumor concentration was of 0.28 and 0.18 %id/g for lung and breast cancer, respectively. the results imply more studies in other thymidine analogs.

Abstract: Introdu o: Altera o a nível corporal do indivíduo como a obesidade, se n o ocorrer fen menos adaptativos eficientes, gerados pelo próprio organismo, pode ter graves consequências de distúrbios posturais. Objetivo: Analisar o padr o postural de adolescentes obesos através da biofotogrametria em escola pública de Teresina-PI. Metodologia: A amostra foi composta de 88 adolescentes (10-14anos) categorizados em grupo controle GC (n=33), grupo sobrepeso-GS (n=24) e grupo Obeso-GO (n=31). Os escolares foram posicionados e fotografados em posi o ortostática frontal anterior, sagital direita e posterior. As press es plantares foram registradas em um podoscópio. Realizou-se avalia o postural utilizando programa Corew Draw 12 baseado no princípio da fotogrametria. Resultados: A incidência de sobrepeso e obesidade foi de 41, 67 e 67,74% no sexo masculino e 58,33% e 32,26% no sexo feminino. A maior incidência de altera es posturais entre adolescentes GO e GS com p<0,001 foi em angulo cervical D e p<0,01 em angulo cervical E. Foi verificado maior apoio da regi o central do pé D e na regi o do calcanhar E com p<0,01 em rela o ao grupo de eutróficos. Na curvatura lombar houve resultado significante com p<0,001. Conclus o: A obesidade em adolescentes pode levar a altera es posturais. Palavras-chave: Obesidade. Impress es Plantares. Postura.
Unconstrained Finite Element for Geometrical Nonlinear Dynamics of Shells
Humberto Breves Coda,Rodrigo Ribeiro Paccola
Mathematical Problems in Engineering , 2009, DOI: 10.1155/2009/575131
Abstract: This paper presents a positional FEM formulation to deal with geometrical nonlinear dynamics of shells. The main objective is to develop a new FEM methodology based on the minimum potential energy theorem written regarding nodal positions and generalized unconstrained vectors not displacements and rotations. These characteristics are the novelty of the present work and avoid the use of large rotation approximations. A nondimensional auxiliary coordinate system is created, and the change of configuration function is written following two independent mappings from which the strain energy function is derived. This methodology is called positional and, as far as the authors' knowledge goes, is a new procedure to approximated geometrical nonlinear structures. In this paper a proof for the linear and angular momentum conservation property of the Newmark algorithm is provided for total Lagrangian description. The proposed shell element is locking free for elastic stress-strain relations due to the presence of linear strain variation along the shell thickness. The curved, high-order element together with an implicit procedure to solve nonlinear equations guarantees precision in calculations. The momentum conserving, the locking free behavior, and the frame invariance of the adopted mapping are numerically confirmed by examples.
Análise epidemiológica de les?es no futebol de sal?o durante o XV Campeonato Brasileiro de Sele??es Sub 20
Ribeiro, Rodrigo Nogueira;Costa, Leonardo Oliveira Pena;
Revista Brasileira de Medicina do Esporte , 2006, DOI: 10.1590/S1517-86922006000100001
Abstract: introduction: several authors have investigated the incidence of injuries occurred in the outdoor soccer game. however, there are only few works analyzing injuries occurred in the indoor soccer game (futsal). the purpose of this study was to analyze the incidence, circumstances, and characteristics of injuries recorded in the indoor soccer during the 15th brazilian sub20 futsal championship. methods: physiotherapists and doctors of every team selection participating in the 15th brazilian sub20 futsal championship answered a questionnaire with the purpose to investigate the occurrence of injuries during the games. the answering rate was 100%. results: 32 total injuries were recorded along 23 games, with a 1.39 injury incidence per game, or 208.6 injuries per 1,000/game. approximately 1 to 3 injuries per game resulted in removal of players from gaming or training. contact injuries were predominant in 65.62% (21 out of 32 injuries), and most of these injuries did not result in removal of the players. conclusions: the present study observed that the injury incidence during the 15th brazilian sub20 futsal championship was similar to the incidence during the indoor soccer tournaments, but higher than those found in the outdoor soccer tournaments, characterizing the specificity of the sports. nevertheless, circumstances and characteristics are similar among them, mainly due to the similar demand of the sports.
