Restauration et étude comparative de deux dioramas du Suriname (musée des Beaux-Arts de Dunkerque et musée des Cultures guyanaises)
Deux dioramas provenant lâun du musĂ©e des Cultures guyanaises et lâautre du musĂ©e des Beaux-Arts de Dunkerque ont Ă©tĂ© confiĂ©s au C2RMF pour Ă©tude et restauration. Une Ă©tude comparative a permis de mieux apprĂ©hender leur mise en Ćuvre et de disposer de donnĂ©es techniques de fabrication utiles Ă la restauration du diorama du musĂ©e des Beaux-Arts de Dunkerque. La future restauration dâun diorama du musĂ©e des Cultures guyanaises Ă Cayenne permettra de complĂ©ter la collecte des donnĂ©es et, Ă travers leur confrontation avec les problĂ©matiques posĂ©es par la restauration du diorama de Dunkerque, de mieux comprendre leurs diffĂ©rences notables dâaltĂ©ration en particulier au niveau des visages. Ces dissemblances sont dâautant plus troublantes que ces illustrations de la vie quotidienne au Suriname se caractĂ©risent plus par leurs similitudes stylistiques, techniques et iconographiques que par leurs diffĂ©rences.Two dioramas, one from the MusĂ©e des Cultures Guyanaises, Cayenne, and the other from the MusĂ©e des Beaux-Arts, Dunkirk, were entrusted to the C2RMF for analysis and restoration. A comparative study provided greater insight into how they were made and technical data about their manufacture that was useful for restoring the diorama in the MusĂ©e des Beaux-Arts, Dunkirk. The future restoration of the diorama from the MusĂ©e des Cultures Guyanaises will complement the data already collected and, through comparison with the difficulties involved in the restoration of Dunkirkâs diorama, will help us to better understand the notable differences in alteration, particularly, in the faces. These dissimilarities are all the more disconcerting since these illustrations of everyday life in Suriname are characterised more by stylistic, technical and iconographic similarities than by their differences
Chapitre 3.2. Pierre Mauroy, entrepreneur politique de modernité urbaine, le regard des grands témoins
La prise de conscience des enjeux de la modernitĂ© urbaine : vers une vision territoriale Ă©largie JĂ©rĂŽme Dupuis, rappelant que câest Ă Maryvonne PrĂ©vot que le colloque doit son titre de Passeur dâavenirs, ouvre le dĂ©bat sur la question de la « bifurcation mĂ©tropolitaine de Lille ». Il convient en effet de sâinterroger sur le cheminement intellectuel, politique, les rĂ©seaux de Mauroy qui lui permettent la prise de conscience des enjeux de la modernitĂ© urbaine. Par quelles logiques dâinfusion, ..

Restauration et étude comparative de deux dioramas du Suriname (musée des Beaux-Arts de Dunkerque et musée des Cultures guyanaises)

The Ground State of Epitaxial Germanene on Ag(111)
International audienceTwo-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, appear very promising due to their outstanding electronic properties, such as the quantum spin Hall effects. While there have been many claims of germanene monolayers up to now, no experimental evidence of a honeycomb structure has been provided up to now for these grown monolayers. Using scanning tunneling microscopy (STM), surface X-ray diffraction (SXRD), and density functional theory, we have elucidated the Ge-induced(109ââââĂ109ââââ)R±24.5âreconstruction on Ag(111). We demonstrate that a powerful algorithm combining SXRD with STM allows us to solve a giant surface reconstruction with more than a hundred atoms per unit cell. Its extensive unit cell indeed consists of 98 2-fold or 3-fold coordinated Ge atoms, forming a periodic arrangement of pentagons, hexagons, and heptagons, with the inclusion of six dispersed Ag atoms. By analogy, we show that the(77ââĂ77ââ)R±19.1âreconstruction obtained by segregation of Ge through an epitaxial Ag/Ge(111) film possesses a similar structure, i.e., Ge pentagons/hexagons/heptagons with a few Ag atoms. Such an organization is more stable than that of pure Ge monolayers and can be assigned to the ground state of epitaxial germanene
Pierre Mauroy, passeur dâavenirs ?
Plus que jamais dâactualitĂ©, en ces temps de tensions parfois entre les Ă©lus locaux et lâexĂ©cutif national dâun cĂŽtĂ©, et dâĂ©lections municipales de lâautre, cet ouvrage sur Pierre Mauroy se situe rĂ©solument dans ce que Michael Keatin appellait le « retour du territoire ». Quelle part peut-on attribuer Ă ce grand Ă©lu socialiste dans le changement de statut du local, dĂ©sormais Ă©rigĂ© en vecteur dâinnovation, dâimpulsion, dâexpĂ©rimentation et dâefficacitĂ© ? La singularitĂ© de cet ouvrage hybride tient dans le choix assumĂ© de restituer des contributions de nature variĂ©e, individuelles ou collectives, Ă©crites et orales pour prendre ainsi la mesure des diffĂ©rentes facettes du personnage et mieux comprendre ses principes dâaction et ses rĂ©alisations. Par les apports quâil contient, cet ouvrage permet dâanalyser lâĂ©lu Mauroy, aux multiples mandats cumulĂ©s, Ă la fois comme un entrepreneur de temps, de territoire(s) (la rĂ©gion, la mĂ©tropole transfrontaliĂšre) et de politiques publiques, dont il cherche Ă sâimputer les rĂ©sultats mais aussi leur mise en rĂ©cit.Faced with tensions between the State and the local government representatives on the one hand, and in the light of the forcoming municipal elections on the other, this book about the former Lille Mayor and Prime Minister Pierre Maury is more than ever in the news
