A new political elite in France : the end of professionalization ?
2020
Actes du projet Parcit (Participation et citoyenneté), financé par les MSH Dijon et Besançon, co-dirigé par A. Alexandre-Collier, D. Andolfatto et A. Goujon, 2017-2019; International audience; Who governs? It is this classic question in political science (Dahl, 1961) that this chapter seeks to answer. It is based on a tradition of studying parliamentary elites (Best & Cotta, 2000 & 2007 ; Norris, 1997). It proposes to analyze the sociological make up of the French National Assembly elected in June 2017. Of course, this is not the sociology of government in the strict sense of the executive power but that of the parliamentary Assembly elected by direct universal suffrage and supposed to adop…
Scientific and technological approaches for sintering and joining of metallic materials by SPS
2013
The flash sintering technique (commonly known as spark plasma sintering, SPS) generates a craze worldwide. This process allows a powder densification from speeds generally 10 to 100 times higher than those of the traditional sintering techniques. In addition, this allows the synthesis of innovative and original dense materials, with a controlled microstructure, complex shapes and, sometimes large sizes. However, the control of scaling and microstructure homogeneity of parts obtained by such a process requires a perfect knowledge of technical equipment including flash sintering to reduce thermal gradients. Modeling is a valuable aid to achieve the improvement of its control. Another potentia…
Malum arbor. El código semiológico de la manzana
1991
A TRAVES DEL ESTUDIO SIMBOLICO DEL MANZANO SE ABORDA LA MAS IMPORTANTE CARACTERISTICA DEL CODIGO SEMIOLOGICO DE ESTA FRUTA Y DEL ARBOL QUE LO OFRECE. MEDIANTE LA ASOCIACION DE LA MANZANA CON EL PECADO ORIGINAL, EL MANZANO HA SIDO IDENTIFICADO COMO UN ARBOL DE SALVACION Y LA MANZANA COMO FRUTO DEL AMOR. IDEAS CODIFICADAS COMO RESULTADO DE LA CULTURA OCCIDENTAL. EL PRESENTE ESTUDIO PLANTEA LAS CUESTIONES DEL CODIGO EN UN SENTIDO DIACRONICO, TENIENDO EN CUENTA LAS TRADICIONES LITERARIAS Y GRFICAS, Y CULMINANDO CON EJEMPLOS QUE TRASMITE LA EMBLEMATICA DE LOS SIGLOS XVI Y XVII. (A.B.C./ L.A.G.)
Topological effects of a rigid chiral spacer on the electronic interactions in donor-acceptor ensembles
2005
Two triads (donor-spacer-acceptor), etTTF-BN-C 6 0 (6) and ZnP-BN-C 6 0 (7), in which electron donors (i.e., exTTF or ZnP) are covalently linked to C 6 0 through a chiral binaphthyl bridge (BN), have been prepared in a multistep synthetic procedure starting from a highly soluble enantiomerically pure binaphthyl building block (1). Unlike other oligomeric bridges, with hinaphthyl bridges, the conjugation between the donor and the acceptor units is broken and geometric conformational changes are facilitated. Consequently, distances and electronic interactions between the donor and C 6 0 are drastically changed. Both donor-spacer-acceptor (D-s-A) systems (i.e., 6 and 7) exhibit redox processes…
Self-Assembly-Directed Organization of a Fullerene–Bisporphyrin into Supramolecular Giant Donut Structures for Excited-State Charge Stabilization
2021
Functional materials composed of spontaneously self-assembled electron donor and acceptor entities capable of generating long-lived charge-separated states upon photoillumination are in great demand as they are key in building the next generation of light energy harvesting devices. However, creating such well-defined architectures is challenging due to the intricate molecular design, multistep synthesis, and issues associated in demonstrating long-lived electron transfer. In this study, we have accomplished these tasks and report the synthesis of a new fullerene–bis-Zn-porphyrin e-bisadduct by tether-directed functionalization of C60 via a multistep synthetic protocol. Supramolecular oligom…
Substrate templating guides the photoinduced reaction of C60on calcite
2014
cited By 7; International audience; A substrate-guided photochemical reaction of C60 fullerenes on calcite, a bulk insulator, investigated by non-contact atomic force microscopy is presented. The success of the covalent linkage is evident from a shortening of the intermolecular distances, which is clearly expressed by the disappearance of the moiré pattern. Furthermore, UV/Vis spectroscopy and mass spectrometry measurements carried out on thick films demonstrate the ability of our setup for initiating the photoinduced reaction. The irradiation of C60 results in well-oriented covalently linked domains. The orientation of these domains is dictated by the lattice dimensions of the underlying c…
The efficacy of a functional therapy program for gambling disorder: A Pilot study
2018
Background: Despite the great progress achieved by treatment approaches for Gambling Disorder (GD) the relevance of studying efficacious therapies still remains high. This pilot study aims at the evaluation of the efficacy of a standardized protocol based on Functional theory for GD. Functional Therapy (FT) is an integrated body-mind therapy.Methods: Twenty-eight pathological gamblers completed the FT protocol consisted in 16 sessions, two times a week for a total duration of two months, in an individual setting. No one of the patients was taking any psychopharmacological therapy. Psychological assessment both at baseline (T0) and at the end of the treament (T1) includes the South Oaks Gamb…
Fonctionnalisation et métallisation des diamantoïdes
2015
The thesis deals with development of synthetic methods for preparation of novel carbon-metal organohybrid based on diamondoid and palladium. The vapor pressure of various diamondoids was measured from a new measurement protocol at solid-vapor thermodynamic equilibrium state. Their volatile tendency opened a possibility to do deposition from gas phase and at various pressure (ambient, primary vacuum, and high vacuum) of diamondoids on silicon or mica substrates. SEM observations have shown that depending on the type of functional groups on the diamondoid, different crystal shapes can be produced (rods, needles, triangles, truncated octahedral form).OMCVD of palladium on functionalized diaman…
Thermo-mechanical analysis of irradiation swelling and design optimization of the IFMIF target assembly with bayonet backplate
2017
Abstract The availability of a high flux neutron source for testing candidate materials under irradiation conditions, which will be typically encountered in future fusion power reactors (ITER, DEMO, FPR), is a fundamental step towards the development of fusion energy. To this purpose, the International Fusion Materials Irradiation Facility (IFMIF) represents the reference option to provide the fusion community with a DEMO-relevant neutron source capable of irradiating samples at a damage rate of up to 20 dpa/fpy (in steel) in a volume of 0.5 l. In the framework of the engineering design activities of IFMIF, ENEA is committed in the design of the lithium target assembly (TA) with removable (…
A genetic integrated fuzzy classifier
2005
This paper introduces a new classifier, that is based on fuzzy-integration schemes controlled by a genetic optimisation procedure. Two different types of integration are proposed here, and are validated by experiments on real data sets of biological cells. The performance of our classifier is tested against a feed-forward neural network and a Support Vector Machine. Results show the good performance and robustness of the integrated classifier strategies.
