Sui Racconti italiani scelti e introdotti da Jhumpa Lahiri

The aim of this paper is to discuss a recent collection of Italian short stories: Racconti italiani scelti e introdotti da Jhumpa Lahiri.Che cosa significa l’ordine alfabetico inverso con cui, per cognome degli autori, sono disposti i Racconti italiani, l’antologia che Jhumpa Lahiri ha recentemente curato per Knopf negli Stati Uniti, Penguin in Inghilterra e Guanda in Italia? Oltre a essere un omaggio all’Elio Vittorini di Americana, la prima grande raccolta della prosa statunitense approntata nel nostro paese (il volume si apre infatti con lui), questa scelta dice sicuramente qualcosa del carattere della antologista e della sua tendenza a rimescolare le carte con metodo, per così dire sposando entusiasmo e disciplina

Cyclic fatigue resistance, torsional resistance, and metallurgical characteristics of M3 Rotary and M3 Pro Gold NiTi files

Objectives: To evaluate the mechanical properties and metallurgical characteristics of the M3 Rotary and M3 Pro Gold files (United Dental). Materials and Methods: One hundred and sixty new M3 Rotary and M3 Pro Gold files (sizes 20/0.04 and 25/0.04) were used. Torque and angle of rotation at failure (n = 20) were measured according to ISO 3630-1. Cyclic fatigue resistance was tested by measuring the number of cycles to failure in an artificial stainless steel canal (60° angle of curvature and a 5-mm radius). The metallurgical characteristics were investigated by differential scanning calorimetry. Data were analyzed using analysis of variance and the Student-Newman-Keuls test. Results: Comparing the same size of the 2 different instruments, cyclic fatigue resistance was significantly higher in the M3 Pro Gold files than in the M3 Rotary files (p < 0.001). No significant difference was observed between the files in the maximum torque load, while a significantly higher angular rotation to fracture was observed for M3 Pro Gold (p < 0.05). In the DSC analysis, the M3 Pro Gold files showed one prominent peak on the heating curve and 2 prominent peaks on the cooling curve. In contrast, the M3 Rotary files showed 1 small peak on the heating curve and 1 small peak on the cooling curve. Conclusions: The M3 Pro Gold files showed greater flexibility and angular rotation than the M3 Rotary files, without decrement of their torque resistance. The superior flexibility of M3 Pro Gold files can be attributed to their martensite phase

HUMANIST REPUBLICANISM: TOWARDS A NEW PARADIGM

Current representations of fifteenth-century political thought are still fundamentally based on Quentin Skinner's neo-republican paradigm. In recent years, however, historians have increasingly complained that the Cambridge School forced Medieval and Renaissance texts into an overmodernizing conceptual framework. This article aims to offer an alternative interpretation by reclaiming the specificity of 'weak' humanist republicanism (compared to the 'strong' republican theory that would rise only later, with the Enlightenment) and by describing it through eight adjectives - fluid, minoritari an. not anti-monarchical, anti-tyrannical, subsidiary, inegalitarian, pedagogical, ideologically defensive. In this picture, Machiavelli comes to represent a first (although partial) moment of discontinuity

Carlo Ginzburg, Il filo e le tracce. Vero, falso, finto

Comme l’indique son sous-titre (Vrai, faux, mensonger : encore un tribraque, après Mythes, emblèmes et traces [Flammarion, 1989] et Histoire, rhétorique, preuve, qui glosait Rapports de force [Seuil, 2003]), dans Il filo e le tracce Carlo Ginzburg est de nouveau aux prises avec la grande question qui l’a occupé dans ses trois précédents recueils d’essais : la tentative de réfuter les convictions sceptiques et néo-pyrrhoniennes des théoriciens postmodernes qui, avec Roland Barthes et Hayden Wh..
