Umberto Baldini, Ornella Casazza and Alessandro Conti: The Artwork and its Existence Through Time
No full textO presente artigo pretende apresentar a teoria de conservação-restauração de Umberto Baldini e Ornella Casazza através de seus questionamentos no que tange à existência das obras de arte no tempo, sua realidade secular-histórica e como não as suprimir no processo de restauração, mantendo visível ao público o seu aspecto arqueológico. Ao mesmo tempo, o artigo visa introduzir o trabalho intelectual do historiador de arte Alessandro Conti, cuja contribuição é a proposição de uma nova História da arte, baseada na sobrevida das obras de arte (sua conservação, destruição ou alterações físicas), doravante propondo um diálogo interdisciplinar entre as áreas para melhor compreender as potencialidades do reconhecimento da esfera arqueológica, contextualizando a discussão também no cenário nacional.Este artículo intenta presentar la teoría de conservación-restauración de Umberto Baldini y Ornella Casazza por medio de sus cuestiones acerca de la existencias de las obras de arte en el tiempo, su realidad secular-histórica y cómo no las suprimir en el proceso de restauración, manteniendo su rasgo arqueológico visible a lo público. El artículo también pretende introducir el trabajo intelectual de lo historiador del arte Alessandro Conti en su contribución hasta una nueva Historia del arte, basada en la supervivencia de las obras de arte (su conservación, destrucción o alteraciones físicas), y propone un diálogo interdisciplinario entre las áreas para mejor comprender el potencial que hay en reconocer el ámbito arqueológico, trayendo la discussion también hasta el escenario brasileño.The present article intends to introduce Umberto Baldini’s and Ornella Casazza’s theory of conservation-restoration through their questions regarding the existence of the work of art through time, their secular-historical reality, and how to not suppress them in the restoration process, maintaining its archaeological aspects visible to the public. At the same time, the article intends to introduce the intellectual work of the art historian Alessandro Conti and his contribution to a new History of Art, based on the survival of the works of art (their conservation, destruction or physical changes), henceforth proposing an interdisciplinary dialogue between the areas to better understand the potential of recognizing the archeological dimension of the objects, also contextualizing the discussion on the Brazilian scenario
The radical right in Europe, between slogans and voting behavior. IHS Political Science Series No. 123, July 2011
No full textThe paper analyzes the radical right‘s attitudes toward the EU focusing in particular on the level of congruence between the programmatic statements of the central office and the voting behavior of their MEPs. It shows that although radical right parties represent a source of opposition to the EU, within the EP they express their dissent making use of the rules of the game, voting with the opposition more than the other forces do, but voting almost as much with the majority. The party public office in the EP is inserted in the legislative process and even more collusive with the other parties of both sides of the political spectrum than the Eurosceptical rhetoric and statements of central office makes the public believe
Interfacial dynamics in rapid solidification processes
No full textThe broad interest in rapid solidification processes originates from the variety of non-equilibrium microstructures found in the solidified materials; most familiar examples are dendrites, lamellar eutectics, cellular and banded structures. In spite of the deep efforts devoted to this subject by the scientific community, the interfacial dynamics is far from being well understood. The aim of this article is to review some recent theoretical developments, which give a diffuse picture of the interfacial region. A new microscopic approach, based on the stochastic dynamics of a lattice of Potts spins, is also discussed
A re-evaluation of pachypes, a pareiasaurian track from the late permian
No full textThe ichnotaxon Pachypes dolomiticus LEONARDI et al., 1975 from the Upper Permian Arenaria di Val Gardena (Northern Italy) was erected on the basis of an isolated pes and assigned to pareiasaurs. Over the last three decades several other footprints have been found, including partial trackways, allowing here to refine the P. dolomiticus features and variability and to confirm the biotaxon correlation with pareiasaurs. Recently, two large reptilian ichnotaxa have been uncovered from the Upper Tatarian of Russia. These have been ascribed respectively to Brontopus giganteus HEYLER & LESSERTISSEUR, 1963 (SUKROV et al. 2007), previously found only in the French Salagou Formation (Lodève Basin), and to Sukhonopus primus GUBIN & BOULANOV in GUBIN et al., 2003. Formal revision of Pachypes make possible to include the aforementioned Russian tracks in it. Additionally, the ichnological data support a Late Permian distribution of Pachypes. Furthermore, footprints from the South African Tapinocephalus Assemblage Zone (Beaufort Group, Karoo Basin), support a correlation of this interval with that of the French ichnofaunas from the Salagou Formation and Les Pradineaux Formation and thus support a Middle Permian distribution of Brontopus. © 2009 E.

Fingering in slow combustion
No full textWe report numerical simulations of the structure of advancing burning fronts under conditions where the dominating transport mechanisms is the diffusion of oxygen and heat. The model we study describes the interplay between two diffusive fields: one which accounts for the destabilizing mechanism leading to the production of a large surface area and the other for a stabilizing mechanism. The typical length scale associated with the observed fingering instability turns out to be a combination of the diffusion lengths associated with the two competing processes

No full textDynamics of vibrofluidized granular gases in periodic structures
No full textThe behavior of a driven granular gas in a container consisting of M connected compartments is studied employing a microscopic kinetic model. After obtaining the governing equations for the occupation numbers and the granular temperatures of each compartment we consider the various dynamical regimes. The system displays interesting analogies with the ordering processes of phase separating mixtures quenched below their critical point. In particular, we show that below a certain value of the driving intensity the populations of the various compartments become unequal and the system forms clusters. Such a phenomenon is not instantaneous, but is characterized by a time scale tau which follows a Vogel-Vulcher exponential behavior. On the other hand, the reverse phenomenon which involves the "evaporation" of a cluster due to the driving force is also characterized by a second time scale which diverges at the limit of stability of the cluster
