Fonction et usage de la lettre de rémission chez les ducs de Bourgogne à la fin du Moyen Âge

2015

The letter of remission is a codified document given by the prince, stopping any procedure against people. It forgives the criminal and brings him back his good fama. It allows the historian to wonder about the forgiveness procedure that was established first by the monarchy, then by several territorial princes notably the dukes of Burgundy. The conditions in which these documents were produced at the end of the Middle Ages, their multiple copies and the copies that were made several decades after the initial pardon and that are conserved in the chartrier of the dukes of Burgundy in the Archives Départementales de Côte d’Or invites us to analyze the different practices through time, first b…

The climate change effect on the african monsoon region : evolution of the precipitation and atmospheric fields in the CMIP3 and CMIP5 simulations un…

2013

The fourth IPCC report in 2007 established the synthesis of previously published work onthe effects of climate change on global and regional scales. It shows in particular that no consensuscan be found with regard to the future of rainfall — and atmospheric dynamics- associatedwith region — African monsoon. This dissertation revisits this issue in the light of new dataand using an approach avoiding over-representation of the number of simulations available forone type of model and taking into account the diversity of models and their evolution in time :twenty general circulation models (GCMs) participating in the exercises CMIP3 (twelve GCMs)and CMIP5 (eight GCMs) under the A1B emissions sc…

Quand les enseignants claquent la porte

International audience; Les démissions de professeurs des écoles, bien que statistiquement limitées, sont un révélateur de la dégradation des conditions de travail des enseignants dans un contexte d’austérité budgétaire, sans que cette question se limite au thème de la revalorisation des salaires.

Contributions to the physical and experimental validation of a simultaneous PET/MRI system dedicated to small animal imaging

2020

Simultaneous PET/MRI is a dynamic research field of both medical and preclinical domains. The ability of integrated systems to acquire the highly complementarity MR morphological and PET functional data in a single examination paves the way to innovative applications. The hereby document presents a series of experimentations dealing with the performance evaluation and the experimental in vivo capacities of such a device. Physical measurements were implemented based on international standards or inspired by articles of reference. The evaluated system consists of a compact SiPM-based PET subsystem fully integrated in a 7 T preclinical MRI based on the dry magnet technology. Experimentations s…

Cavités plasmoniques et nanosources optiques

2013

Optical microcavities exhibit high resonance quality, so that, they are of key interest for the design of low-threshold lasers or for achieving strong coupling regime. But, such systems support modes whose the volume remain diffraction limited.In this manuscript, we are interested in their plasmonic counterparts because they support confined modes at the sub-wavelength scale. First, we study an in-plane plasmonic cavity which is the transposition of 1D optical cavity to surface wave. We characterize the cavity by measuring the fluorescence lifetime of dye molecules deposited inside.Then, we are interested in 3-dimension mode confinement achieved by spherical metal nanoparticles. We discuss …
