Le site de Gaillardon à Ménétru-le-Vignoble (Jura) : un établissement de hauteur de l'Antiquité tardive et du haut Moyen Âge

L'étude de l'établissement de Gaillardon à Ménétru-le-Vignoble s'inscrit dans le cadre d'un programme de recherche pluridisciplinaire engagé sur les sites de hauteur de l'Antiquité tardive et du haut Moyen Âge dans le département du Jura. Créé ex nihilo vers le début du ve siècle, ce lieu semble avoir été occupé de manière permanente jusqu'au vie siècle. Les aménagements identifiés à l'intérieur de l'enceinte maçonnée, qui enserre une superficie de 1,5 ha, suggèrent une concentration d'activités artisanales diversifiées. Certaines catégories de mobilier reflètent un niveau de vie aisé d'une partie des occupants ainsi que la présence d'une garnison ou d'une milice armée. Cet établissement participe à un phénomène plus large d'émergence de nouvelles places fortifiées aux fonctions complexes, qui ne se réduisent pas à l'explication longtemps invoquée de refuge temporaire destiné à une population rurale

Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications.

BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity. In corneal refractive surgery, the detection of mild forms of ectasia pre-operatively is essential to avoid post-operative progressive ectasia, which also depends on the impact of the procedure on the cornea. METHOD: The advent of 3D tomography is proven as a significant advancement to further characterize corneal shape beyond front surface topography, which is still relevant. While screening tests for ectasia had been limited to corneal shape (geometry) assessment, clinical biomechanical assessment has been possible since the introduction of the Ocular Response Analyzer (Reichert Ophthalmic Instruments, Buffalo, USA) in 2005 and the Corvis ST (Oculus Optikgerate GmbH, Wetzlar, Germany) in 2010. Direct clinical biomechanical evaluation is recognized as paramount, especially in detection of mild ectatic cases and characterization of the susceptibility for ectasia progression for any cornea. CONCLUSIONS: The purpose of this review is to describe the current state of clinical evaluation of corneal biomechanics, focusing on the most recent advances of commercially available instruments and also on future developments, such as Brillouin microscopy.(undefined)info:eu-repo/semantics/publishedVersio

Les minéralisations Cu-(Ni-Bi-U-Au-Ag) d'Ifri (district du haut Seksaoua, Maroc) : apport de l'étude texturale au débat syngenèse versus épigenèse. <br /> The Cu---(Ni---Bi---U---Au---Ag) mineralization of Ifri (‘Haut Seksaoua' district, Morocco): contribution of a textural study to the discussion syngenetic versus epigenetic

The Cu ore of Ifri is a chalcopyrite stockwork hosted by Cambrian formations and was until now interpreted as a syngenetic massive sulphide deposit. Textural studies highlight two generations of pyrite early (Py I) and late (Py II) with respect to the regional deformation. The chalcopyrite stockwork overprinted Py II, outlining the epigenetic nature of the Cu mineralization. Regarding the origin of Cu-depositing fluids, the presence in the stockwork paragenesis of an U, W, Sn association and preliminary Pb/Pb dating of a brannerite belonging to this association suggest a contribution of the Tichka granite
