Desenvolvimento de um código computacional para simulação e análise de espectros atômicos

The aim of this work was the development a computer code for simulation and analysis of atomic spectra from databases constructed from the literature. There were created four routines that can be useful for spectroscopic studies in the atomic processes of laser isotope separation. In the first routine, Possible Transitions, the program checks the possible electron transitions from an energy level of the atom present in the database considering the selection rules for an electric dipole transition. The second routine, Locator Transitions, checks the possible electronic transitions within a user-specified spectral region. The routine Spectra Simulator creates simulated spectra using the graphical application gnuplot through lorentzian curve and finally, the routine Electronic Temperature determines the temperature of electronic excitation of the atom, thought the Boltzmann Plot Method. To test the reliability of the program there were obtained experimental emission spectra of a hollow cathode discharge of dysprosium and argon as a buffer gas. The hollow cathode discharge has been subjected to different values of operating currents and pressure of inert gas. The spectra obtained were treated with the assistance of program routines developed (Transition Locator and Spectra Simulator) and temperatures electronic excitation of the atoms of dysprosium in the different discharge conditions were calculated (routine Electronic Temperature). The results showed that the electronic excitation temperature of the neutral dysprosium atoms in the hollow cathode discharge increases with increasing current applied to the cathode and also by increasing the gas pressure buffer. The determination coefficients, R2, obtained by the Electronic Temperature routine using the linear adjust of the Boltzmann Plot Method were greater...

A Bienal do Vazio: análise comparativa das estratégias de tomada de posição dos jornais O Estado de S. Paulo e Jornal Semanal da 28ª Bienal de São Paulo

This paper proposes a comparative analysis of cultural critical, articles and reports related to the 28th International Biennial of Art of São Paulo published in the newspapers O Estado de S. Paulo and Jornal Semanal da 28ª Bienal de São Paulo, from October to December 2008. Specific aims of analysis are how an institution devoted, like Biennial, creates mechanisms to defend their choices and hegemonic position within the arts field and also to examine how this dedication can be demystified by critics from diffusion field not linked to the institution. For the study will be used the concepts of field, hierarchy of legitimacy and position of an agent developed by Pierre Bourdieu, as well as historical notions of Cultural Journalism and journalistic criticism

Globalização, estado-nação e organização da sociedade civil

The questions that guide this article deal with the nation-State configuration and civil society organization, as well as the contours of the relation between both in the globalization context. As a qualitative change of internationalization, globalization brings to the social sciences field the discussion about its social impacts and the problematization about extinction of State. Thus, the article is guided by the debate between determined authors that deal with the analysis about new strategies of the State action, in order to understand where national States go, seeking to adapt themselves to the new context of Capital globalization.

Organizações sindicais, Estado e sociedade civil no Brasil

During a long historical process of over a century, the trade union movement gathered a significant amount of achievements. The limits and the extent of these achievements cannot be dissociated form the complex relations between State and civil society in Brazil.

Análise dosimétrica de perfis de distribuições radiais de doses relativas de um aplicador de betaterapia de 90Sr+90Y utilizando o código MCNP-4C e filmes raiocrômicos

Although they are no longer manufactured, the applicators of 90Sr +90Y acquired in the decades of 1990 are still in use, by having half-life of 28.5 years. These applicators have calibration certificate given by their manufacturers, where few have been recalibrated. Thus it becomes necessary to accomplish thorough dosimetry of these applicators. This paper presents a dosimetric analysis distribution radial dose profiles for emitted by an 90Sr+90Y betatherapy applicator, using the MCNP-4C code to simulate the distribution radial dose profiles and radiochromium films to get them experimentally . The results with the simulated values were compared with the results of experimental measurements, where both curves show similar behavior, which may validate the use of MCNP-4C and radiochromium films for this type of dosimetry
