Arquivo X e a proje o utópica da realidade: o pensamento tecnológico e as novas utopias
Pedro Henrique Reis
Galáxia , 2011,
Abstract: Uma análise crítica de um episódio da série de televis o Arquivo X, do ano de 1998, com o objetivo de revelar as características e nuances, dentro de um objeto da Cultura da Mídia, do pensamento tecnológico e da proje o utópica da realidade através das representa es de tecnologias de sublima o do espa o e do tempo e da fantasia de supera o das condi es humanas. A série, que se baseia em encontros e mistérios envolvendo tecnologia e o sobrenatural, mostra investigadores que confrontam suas presun es sobre a realidade e se equilibra sobre duas premissas: a da superioridade do herói humano e da inventividade e poder que o desconhecido tem em assombrar a própria existência humana com fantasmagorias oriundas de mais de quatro séculos de fantasias e pesadelos tecnológicos.

Granular segregation as a critical phenomenon
Pedro M. Reis,Tom Mullin
Physics , 2002, DOI: 10.1103/PhysRevLett.89.244301
Abstract: We present the results of an experimental study of patterned segregation in a horizontally shaken shallow layer of a binary mixture of dry particles. An order parameter for the segregated structures is defined and the effect of the variation of the combined filling fraction, $C$, of the mixture on the observed pattern formation is systematically studied. The surprising result is that there is a critical event associated with the onset of the pattern, at $C=0.647\pm0.049$, which has the characteristics of a second order phase transition, including critical slowing down.

Ana Messias, Jo?o Paulo Tondela, Salom?o Rocha, Rita Reis, Pedro Nicolau, Fernando Guerra
Open Journal of Radiology (OJRad) , 2013, DOI: 10.4236/ojrad.2013.33023
Abstract:

Objectives: This paper describes a technique to produce individualized X-ray positioning devices for intraoral digital imaging of dental implants with long-term stability. Materials and Methods: An X-ray positioning device was built for Gendex? Visualix? eHD sensor, using the Dentsply rinn XCP-DS? system individualized by the incorporation of the bite piece within an acrylic stent to perform successive standardized radiographs to 16 patients. X-ray tube stabilization was achieved with polivinylsiloxane. Series of 3 radiographs were taken to each patient in different moments. Specific linear measurements as the implant diameter (mesio-distal width) and the height between consecutive threads (thread pitch) were made to all radiographs to determine the reproducibility and accuracy of the procedure. Results: The intraclass correlation coefficient for the mesio-distal width was 0.964 [(0.920 - 0.986) 95% CI] (p < 0.01) and 0.990 [(0.976 - 0.996) 95% CI] (p < 0.01) for the thread pitch. Bland-Altman plots comparing implant diameter showed mean bias of 0.01 ± 0.01975, 0.01 ± 0.02243 and 0.0006 ± 0.025 for groups 1 - 2, 1 - 3 and 2 - 3 respectively. Mean bias of 0.0024 ± 0.00552, 0.0027 ± 0.00552 and 0.0003 ± 0.0012 was found for the thread pitch analysis of groups 1 - 2, 1 - 3 and 2 - 3. One sample t-test for trueness of mesio-distal width, thread pitch and ratio showed mean difference of 0.00156 mm for the test value of 3.3 (p = 0.9), -0.00026 mm for 0.8 (p = 0.96) and 0.0124 for 4.125 (p = 0.72), respectively, after the application of a magnification correction factor. Conclusion: The device produced reproducible images in different moments and was suitable for comparative clinical examinations of marginal

Brancante, Pedro Henrique;Reis, Rossana Rocha;
Lua Nova: Revista de Cultura e Política , 2009, DOI: 10.1590/S0102-64452009000200003
Abstract: based on two central questions - "is there a process of securitization of migration taking place?" and "is the concept of societal security useful for understanding some of the dilemmas faced by modern society?" - this article proposes a map of the recent academic debate, focusing on the european case. after analyzing the ideas of several and well-known authors, the article develops three critical arguments to the concept of "societal security", advanced mainly by the members of the copenhagen school, which stimulates the dangerous process of securitization of migration.
