What is (not) the point of just transition in food systems?
2022
Food systems are confronted with a low-carbon transition challenge. The need for significant emission reductions in industrial food systems implies significant systemic transformations in food production, processing, and consumption. The wide-reaching impacts of such transformations have evoked public discussion and academic research on just transition in food systems. The undisputable legitimacy of the idea of just transition makes it an attractive concept for all food system actors who might be affected by low-carbon transition policies in direct and indirect ways. Some of the claims that are being made are warranted claims for justice, some merely defend the achieved privileges and benef…
(2010). Microstructure and magnetic properties of colloidal cobalt nano-clusters.
2010
The magnetic response of nanometer sized Co nanoparticles (NP) prepared using reverse micelle solutions are presented. The use of complementary structural and morphological probes (like transmission electron microscopy, high resolution electron microscopy, X-ray absorption spectroscopy) allowed to relate the magnetic properties to the size, morphology, composition and atomic structure of the nanoparticles. All data agree on the presence of a core–shell structure of NPs made of a metallic Co core surrounded by a thin Co-oxide layer. The core–shell microstructure of NPs affects its magnetic response mainly raising the anisotropy constant.
Crossing the boundary between fcc and hcp: the structure of nanosized cobalt is unraveled by a model of size distribution, shape and stacking faults …

The properties of nanostructured cobalt in the fields of magnetic, catalytic and biomaterials depend critically on Co close-packing. In this paper we report a structural analysis of nanosized cobalt based on the whole XRD pattern simulation allowed by the Debye equation. The underlying structural model involves statistical sequences of cobalt layers and produces simulated XRD powder patterns bearing the concurrent signatures of hexagonal and cubic close packing. Size distribution, shape and distance distribution between pairs of atoms are also modelled. The simulation algorithm allows straightforward fitting to experimental data and hence the assessment of the model parameters. Analysis of …
Comparación de los resultados radiológicos, clínicos y analíticos de un vástago con cuello modular y su homólogo monobloque en la artroplastia total …
2022
Introducción: La artroplastia total de cadera es uno de los grandes hitos de la ortopedia moderna. Los vástagos con cuellos modulares fueron introducidos con la ventaja teórica de permitir un ajuste más exacto de la anatomía. La hipótesis de nuestro trabajo es que el vástago modular H-MAX M con cuellos intercambiables permite restaurar el offset femoral y la longitud de miembros, de forma más ajustada que con el vástago monobloque homólogo H-MAX S, obteniendo con ello mejores resultados clínico-funcionales sin añadir los riesgos de una elevación sérica de cromo ni cobalto. El objetivo de nuestro trabajo es comparar los resultados radiológicos, clínicos y analíticos de un vástago con cuell…
Dynamics of brain activity underlying working memory for music in a naturalistic condition
2012
Working memory (WM) is at the core of any cognitive function as it is necessary for the integration of information over time. Despite WM’s critical role in high-level cognitive functions, its implementation in the neural tissue is poorly understood. Preliminary studies on auditory WM show differences between linguistic and musical memory, leading to the speculation of specific neural networks encoding memory for music. Moreover, in neuroscience WM has not been studied in naturalistic listening conditions but rather in artificial settings (e.g., n-back and Sternberg tasks). Western tonal music provides naturally occurring motivic repetition and variation, recognizable units serving as WM tri…
Emotions, stratégies politiques et engagement citoyen
2022
Longtemps décriées pour leur manque de rationalité, les émotions sont pourtant omniprésentes dans les débats politiques et sociétaux actuels. Alors que la sphère publique contemporaine est traversée par des clivages profonds, comment rendre compte des articulations entre émotions collectives, mobilisations politiques et participation citoyenne ? Quels sont les contextes politiques et culturels qui favorisent l'expression des émotions ? Quelle est l'influence des outils numériques dans la formation de communautés émotionnelles et dans l'émergence de nouvelles formes de contestation ? De quelle façon les stratégies d'action des collectifs citoyens intègrent-elles les émotions pour convaincre …
Postbuckling analysis of cracked stiffned plates by pb–2 Rayleigh-Ritz method
2015
A Rayleigh-Ritz approach for the analysis of buckling and post-buckling behavior of cracked composite stiffened plates is presented. The structure is thought as the assembly of plate elements modeled by the first order shear deformation theory. Continuity along the edges common to contiguous elements are enforced by using penalty techniques, which also allow to straightforwardly implement efficient crack modeling strategies. General symmetric and unsymmetric stacking sequences are considered and numerical procedures have been developed and used to validate the present solution by comparison with FEA results. Original results are also presented for post-buckling solution of multilayered stif…

The world of public research seems at first sight to be very little concerned by themanagement issues of the business world in which the right decisions must be taken and forwhich there is an obligation to perform. The very idea of coaching researchers seemsincongruous. The purpose of this study is to challenge this idea, by describing precisely whatthe profession of researcher is in the world of public research - their belonging to very complexstructures and the demanding challenges they have to face - then by studying thecontributions of cognitive-behavioural coaching methodologies. The analysis of the practiceshows that coaching based on constructivist psychology can lead to a better pra…
