This paper aims at testing the mechanical relevance of the petrological model of anorthosite massif diapiric emplacement. The Egersund-Ogna massif (S. Norway) is of particular interest because recent petrological and geochronological data constrain the initial geometry, emplacement conditions and timing (about 2 m.y.). The formation of this anorthosite massif is in agreement with the classical petrological model, in which accumulation of plagioclase takes place in a deep-seated magma chamber at the crust-mantle limit, from which masses of plagioclase separate and rise through the lower crust up to the final level of emplacement at mid-crustal depths. The Egersund-Ogna massif also displays a foliated inner margin, in which strain ellipsoids have been reconstructed by investigating at 51 sites the deformation of megacrysts of high-alumina orthopyroxene. Based on these petrological data, a model made up of one rigid layer (upper granitic crust) and three viscous layers (lower part of the granitic crust, noritic lower crust and anorthosite) has been built up. The upper crust behaviour is represented by an elastoplastic law and the viscous layers obey elastic-viscoplastic laws with Newtonian viscosity. An inverse density gradient is considered between the lower crust (d = 3.00) and the anorthosite (d = 2.75), the loading consisting only in gravity. The modelling is carried out under axisymmetrical conditions, using the LAGAMINE finite-element code coupled with an automatic re-meshing algorithm designed to deal with large strains in complex structures. The results show that, from a mechanical point of view, the diapirism model is a robust and consistent assumption for the emplacement of anorthosites, because realistic diapir and rim-syncline shapes are obtained. Moreover, the numerically obtained emplacement time (about 2.5 m.y.) is in agreement with the available geochronological data, and the computed strain field is coherent with field measurements, especially regarding the circumferential extension, which becomes the largest extension strain component in the expansion phase.

The Gulf of Corinth in Greece is an active continental rift propagating westward toward the Aegean subduction zone. GPS data shows that deformation rate reaches a maximum of 15 mm/yr at its western tip. The style of extension and strain distribution is well documented offshore in the eastern and central parts of the rift (Bell, 2009). At its most active western extremity, published offshore data is not sufficient to characterize the deformation pattern. High resolution seismic profiles were thus acquired in that region within the framework of the SISCOR project to improve our understanding of fault evolution, seismicity and to be able to construct mechanical models of deformation. Here we investigate the spatio-temporal pattern of the basin subsidence and deposition with sparker data acquired in November 2011. Active faults and correlative time horizons were first mapped. The stratigraphy was then correlated with the eustatic sea-level curve. This sequence stratigraphic interpretation is possible because there are strong glacial-interglacial variations in the depositional environment. In fact lacustrine conditions prevail within the gulf during glacio-eustatic lowstands and are characterized by low amplitudes seismic facies. So synrift sediment isopachs over the last 12 000 and 130 000 yrs could be produced. The interpreted data allow us to: (1) compare deformation pattern at the western tip of the Gulf with the more mature central and eastern part of the Rift; (2) constrain the pattern and the timing of deformation as well as rates of faulting.

This paper presents a three-parameter kinematic model for the deformation patterns of deep continuous transfer girders. The three degrees of freedom of the model are the average strains along the top and bottom longitudinal reinforcements within each shear span, as well as the transverse displacement in the critical loading zone. The model is validated with the help of a large test of a two-span continuous beam performed at the University of Toronto. It is shown that the apparently complex deformation patterns of the specimen are captured well by the kinematic model. [less ▲]

This article describes the deformation of an elastic pipe submitted to gravity and to an internal fluid flow. The pipe is clamped horizontally at one end and free at the other end. As the fluid velocity increases, the shape changes from an elastic beam deflected by its own weight towards an horizontal posi- tion. The shape of the pipe is characterized experimentally and is compared with a theoretical model based on the Euler-Bernoulli approximation and the conservation of the fluid momentum. We study how the determination of the pipe deformation provides an estimation of the conveyed fluid flow. Finally, the vertical force produced by the conveyed fluid to lift off a mass is deduced.

This work presents some important features of the normal articular structures and a definition of the degenerative osteo-arthropathy that points the involvement of all the joint structures. The pathogeny of the pathology is tackled by the potential risk factors and by the cartilage-cartilage, synovium-cartilage and bone-cartilage cycles that lay particular emphasis on the interaction between the different joint structures. The diagnostic tools of the degenerative osteo-arthropathy like the conventional or recent imaging techniques (magnetic resonance imaging, scintigraphy and tomography) and the biomarkers of the cartilage and bone metabolisms are listed. The pathogeny of the degenerative osteo-arthropathy is complex and involves different factors. This disease is characterised by an imbalance between the anabolic and catabolic processes of the cartilage metabolism. Inflammation is also present and lead to the clinical signs. The synovitis, the liberation of degradation mediators, the mechanical stresses and/or the subchondral bone are part of the pathogeny at different degrees. The development of recent imaging techniques and the biomarkers of the cartilage and bone metabolisms allow the precise description of the lesions and give some additional information on the pathogeny of the osteo-arthropathy. These recent techniques raise new questions and allow the in-depth analysis of the study of the osteo-arthropathy. [less ▲]

Pourritures, cadavres, corruptions, insectes et vermines, puanteurs, horreurs visuelles, matières et saveurs repoussantes, ordures, secrétions et déchets corporels… Nombreux sont les objets qui, du plus lointain de nos histoires et de nos cultures, suscitent le dégoût et agressent notre système perceptif ; les sens sont touchés avec une immédiateté qui les entraîne irrésistiblement à l’écart de cet objet qui nous fait détourner le regard, nous boucher les narines, nous éloigner physiquement afin d’éviter contact et proximité avec ce qui répugne. Pourtant, le dégoût fascine. Les artistes s’en emparent qui, dans la littérature, la peinture, l’art performatif ou le cinéma, prennent pied et appui sur le dégoût, exaltant les motifs et la monstration de ce qui au départ révulse. <br /> <br />Comment définir le dégoût, malgré la multiplicité de ses objets ? Qu’en est-il de son histoire, tant du mot « dégoût » que du sentiment lui-même ? Quelles sont les relations qui unissent goût et dégoût ? Qu’en est-il du dégoût de soi ? Que dire, enfin, de la dimension éthique, politique et sociale d’une émotion qui pèse inévitablement dans les interactions humaines ? <br /> <br />L’étude du dégoût est difficile. En effet, cette « émotion plurielle » est dotée d’une connotation très négative et a souvent été laissée aux marges du savoir. Depuis quelques décennies, cependant, les disgust studies se multiplient. Douze chercheurs en sciences humaines, provenant des disciplines les plus variées, proposent ici une réflexion théorique commune, explorant l’histoire, le langage, la philosophie, la psychologie, l’éthique et l’esthétique du dégoût, convaincus que les réflexions les plus riches sur le sensible, les émotions, les affects ou les sentiments se fondent sur le dialogue entre disciplines, en confrontant les méthodes, les approches et les objets. Les figures multiples du dégoût explorées dans cet ouvrage révèlent une émotion-limite, qui échappe aux partages clairement institués, tant elle se caractérise par la profusion et l’indétermination, expliquant le trouble, l’ambivalence, et la fascination du dégoûtant.
