The version of Fig. 4 that was inadvertently included in the original publication did not show the results of Monte Carlo modeling referred to in the caption and the text. The correct figure and its caption are shown below. This does not affect the conclusions of the article. FIG. 4. Integrated K ␣ fluorescence energy versus mass fraction of Cu fluor in Al/ Cu/ Al targets. The front Al layer varied from zero to 500 m, the Cu layer was 20-25 m. The back Al layer was 100 m for the four ϫ points, and 40 m for the ϩ, 10-20 m otherwise. The open symbols show the predictions from Monte Carlo modeling with an arbitrary relative normalization. The back Al layer in the model is either 16 m ͑square͒ or 100 m ͑triangle͒.
A emergência do "moderno" conceito de revolução The emergency of the "modern" concept of revolution O texto busca refletir sobre a emergência daquele que é considerado o sentido moderno do conceito de Revolução, tendo como objetivo a discussão da trajetória que passa do significado tradicional e circular às circunstâncias que possibilitaram a análise da Revolução como uma nova Era, distinta das experiências do passado. Nesse sentido, acredita-se que a Revolução Inglesa de 1688 foi fundamental nesse processo, no fornecimento do vocabulário e na experiência temporal. A forma com que os britânicos do século XVIII refletiram sobre os eventos revolucionários do seiscentos formaram o conceito moderno, antes mesmo que os acontecimentos americanos e franceses viessem à tona. No entanto, se foi uma inspiração para as revoluções modernas, os ingleses setecentistas defenderam sua estrutura política e social, exaltando o caráter conservador de 1688, procurando se diferenciar dos eventos na França, que pareciam desintegrar toda ordem conhecida. Revolução; Modernidade; História dos Conceitos. The text seeks to reflect on the emergence of what is considered the modern sense of the concept of Revolution, aiming to discuss the trajectory that passes beyond the traditional and circular meaning to the circumstances that made possible an analysis of the Revolution as a new era, distinct from the experiences of the Past In this sense, it is believed that the English Revolution of 1688 was central to this process. The way the eighteenth-century British reflected on the revolutionary events of the sixteenth century formed the concept, even before American and French events came to light. However, if it was an inspiration for modern revolutions, the seventeenth-century English sought to defend its political and social structure by extolling the conservative character of 1688, trying to differentiate itself from events in France that seemed to disintegrate every known order.
