Ivy and Bones: ruins and reversibility during the Blitz
2012
"Ivy and bones: ruins and reversibility during the Blitz" examines how the representation of the ruins of the Blitz is informed by the aesthetic and semiotic tension between abstraction, modernist purity and picturesque accretion. Subsequently building on the notion of reversibility, it explores the way wartime destruction and/or cultural decline is recorded as well as counteracted and compensated for in works by Elizabeth Bowen, Herbert Furst, Claire Leighton, Rose Macaulay, John Piper, and Virginia Woolf. The trope of reversibility provides a template to consider some of the sites where aesthetic conflicts are re-enacted, from blitzed spaces to the printed page as threatened modernist art…
La rencontre entre Thérèse d'Avila et Francisco de Osuna autour du Recueillement: des "Abécédaires spirituels" au "Livre des Demeures"
2015
International audience; A l’occasion de cette communication, je me propose d’aborder le thème de la rencontre entre Thérèse d’Avila et un de ses maîtres spirituels indirects, le Franciscain andalou Francisco de Osuna. C’est à travers la lecture du Troisième Abécédaire spirituel (1527) ―ouvrage rédigé dans un contexte polémique marqué par la récente condamnation de l’illuminisme par l’Inquisition de Tolède (1525)― que la jeune Thérèse s’est initiée en 1538 à l’oraison de Recueillement. Après une présentation rapide de la vie et de l’œuvre prolifique ―Abécédaires castillans et sermonnaires latins― de ce maître spirituel et prédicateur très apprécié au XVIème siècle, je tâcherai de donner une …
Consolidation and densification mechanisms of copper powder during Spark plasma sintering (SPS)
2015
Spark plasma sintering is a manufacturing process that leads to dense materials with fine microstructures. SPS combines heating and uniaxial load as well as the Hot Pressing (HP) process but the material is heated using a pulsed current. The phenomena occurring during SPS are not fully understood and are still an open point: -Which densification and consolidation mechanisms are involved during SPS? -Why is sintering by SPS more efficient than sintering by traditional ways such as HP? –Does electrical current modify the sintering mechanisms? The aim of this work is to answer these questions in the case of spherical copper powder (from 10 to 50 µm). Comparisons between SPS and HP were perform…
Migmatites in the Ivrea Zone (NW Italy): Constraints on partial melting and melt loss in metasedimentary rocks from Val Strona di Omegna
2013
Abstract The mid to lower crustal metamorphic field gradient through amphibolite and granulite facies rocks in the Ivrea Zone offers the potential to study partial melting and melt loss in the crust. Metapelitic rocks in Val Strona di Omegna show a progressive evolution in migmatite structures from metatexites with rare isolated leucosome veins in the amphibolite facies rocks to stromatic migmatites and diatexites in granulite facies rocks. Little field or petrographic evidence for melting can be seen on crossing the position of the modelled wet solidus, consistent with the small amounts of melt predicted to occur by H2O-saturated melting. The first field evidence for partial melting, in th…
Long-term deformation and fluid-enhanced mass transport in a Variscan peridotite shear zone in the Ivrea Zone, northern Italy: a microtextural, petro…
1995
The microtextural, petrological and geochemical study of a ductile shear zone in the phlogopite peridotite of Finero/Ivrea Zone (northern Italy) reveals the long-term deformation of this zone. The zone is divided into a protomylonitic and an ultramylonitic part. Both parts reflect different periods of deformation, although the orientation of the mineral lineations does not change. In the coarse-grained part (period 1) the deformation started under granulite facies conditions (about 775°C). Olivine, ortho- and clinopyroxene and phlogopite recrystallized dynamically. In the ultramylonitic part relics of the granulite facies event and evidence for a continuous or two-stage deformation history …
Chimie de coordination du phosphore aux métaux du groupe 11 : progrès en catalyse de couplage C-N au Cu(I) et nouveaux complexes polyphosphines de l'…
2014
Nowadays, sustainable development encourages chemists to develop new economic and ecologic synthesis, because natural ressources are reducing. Most exploited ressources are gas and petroleum, but precious metals are also essential. This thesis is focusing on the enhancement of gold and copper complexes, obtained in our laboratory from phosphorous-based ligands. In the first part, we will develop a new system for the N-arylation of pyrazoles from a copper complexe coordinated by a new hybrid phosphinoalkene ligand. In the second part, coordination properties of gold to different ferrocenic polyphosphine will be studied. Several new innovative complexes will be isolated, and could be used in …
Vers des systèmes viticoles économes en pesticides
2022
L’utilisation de produits phytosanitaires (cuivre, soufre et produits de synthèses) est à ce jour le moyen de lutte le plus efficace pour garantir une vendange qualitative et quantitative (Pujol, 2017). Face aux préoccupations sociétales croissantes concernant l’impact des pesticides sur l’environnement et la santé, la viticulture se doit pourtant de réduire sa dépendance aux produits phytosanitaires. Une transition agroécologique est ainsi nécessaire et implique de changer les pratiques afin de parvenir à diminuer l’utilisation des produits phytosanitaires. Le réseau DEPHY-Ferme a été créé en 2010 afin d’initier et stimuler cette transition agroécologique et répondre aux enjeux ambitieux i…
Drunkenness in Early Modern France (XVI - XVIIIth century)
2010
From the 16th to the 18th century, a deeply rooted tradition of open and celebrative inebriation existed in the kingdom of France. Society permitted collective, festive and social drinking. But many opposed drunkenness. In France at that time, absolute monarchy from divine right was developing, and the fundamental opposition came from religious and civic powers. Drunkenness was seen either as a sin or as a vice of variable severity that drove others to commit it as well. From 1536, a connection was made between sin and crime: inebriation became an auxiliary crime. However, in face of the culture of inebriation, religious and political authorities acted pragmatically and did not really attem…
Local disequilibrium of plagioclase in high-temperature shear zones of the Ivrea Zone, Italy
1995
Microstructural and chemical analysis of plagioclase in 20 superficially similar amphibolite facies ductile shear zones in metagabbors and amphibolites of the Ivrea Zone in Italy reveals significant differences in An and Ba contents. Plagioclase, which was deformed at P-T conditions lower than those of the wall rocks, occurs in the following four different microstructural situations with different chemical compositions: (i) relatively undeformed porphyroclasts, (ii) dynamically recrystallized grains and subgrains rimming the porphyroclasts, (iii) infill of microcracks cross-cutting the porphyroclasts and (iv) fine-grained recrystallized grains in the matrix of the shear zones. The differenc…
