Der Spur auf der Spur. Sur les traces de la trace
2016
Hinter dem scheinbar einfachen lexikalischen Gewand der »Spur« verbirgt sich eine überraschende Komplexität: Was ist eigentlich eine Spur? Was sind ihre typischen Merkmale? Wodurch unterscheidet sie sich von Abdruck, Zeichen und Indiz? Die Beiträge des vorliegenden Bandes reflektieren den Spurbegriff aus deutsch-französischer sowie aus interdisziplinärer Perspektive. Zu Wort kommen Philosophie, Literatur, Geschichte, Archäologie, Kunstgeschichte, Urbanistik, Kulturwissenschaft und Psychoanalyse.
Sources optiques infrarouges impulsionnelles ultra-courtes et spectralement ultra-larges générées par effet Raman dans les fibres creuses
2019
Gas-filled Hollow-Core Photonic Crystal Fibers (HC-PCF) are efficient tools regarding ultra-wide and coherent optical frequency combs by Stimulated Raman Scattering (SRS). Coherence is reached thanks to highly transient regime as it allows amplification, from quantum to macroscopic level, of a unique spatial and temporal mode (TSM). This results in the generation of Stokes waves with a well-determined phase. The present work details on which time scale coherence can subsist, between two consecutive pulses. The possibility of making a new kind of mode-lock is studied. Then the extreme versatility of gas-filled HC-PCF is illustrated by presenting different kind of new laser sources, exploitin…
The phenolic compounds of olive oil: structure, biological activity and beneficial effects on human health
2005
AbstractThe Mediterranean diet is rich in vegetables, cereals, fruit, fish, milk, wine and olive oil and has salutary biological functions. Epidemiological studies have shown a lower incidence of atherosclerosis, cardiovascular diseases and certain kinds of cancer in the Mediterranean area. Olive oil is the main source of fat, and the Mediterranean diet's healthy effects can in particular be attributed not only to the high relationship between unsaturated and saturated fatty acids in olive oil but also to the antioxidant property of its phenolic compounds. The main phenolic compounds, hydroxytyrosol and oleuropein, which give extra-virgin olive oil its bitter, pungent taste, have powerful a…
Oleuropein multicompartment nanovesicles enriched with collagen as a natural strategy for the treatment of skin wounds connected with oxidative stres…
2021
Aim: Collagen-enriched transfersomes, glycerosomes and glytransfersomes were specifically tailored for skin delivery of oleuropein. Methods: Vesicles were prepared by direct sonication and their main physicochemical and technological properties were measured. Biocompatibility, protective effect and promotion of the healing of a wounded cell monolayer were tested in vitro using fibroblasts. Results: Vesicles were mainly multicompartment, small (∼108 nm), slightly polydispersed (approximately 0.27) and negatively charged (~-49 mV). Oleuropein was incorporated in high amounts (approximately 87%) and vesicles were stable during four months of storage. In vitro studies confirmed the low toxicit…

Penser la peine à l'âge des Lumières
2012
L'image du mouvement intellectuel des Lumières qui remettrait en cause le droit de punir des siècles précédents, doit être nuancée. Philosophie et histoire sont convoquées pour savoir comment on pense la peine au XVIIIe siècle. L'histoire de la justice permet de se pencher sur la diversité des systèmes judiciaires européens et d'observer l'évolution de leur "rigueur" dans les discours normatifs et les pratiques pénales. Quant à l'histoire de la philosophie, revenant notamment sur Foucault, elle renoncera à présenter la pensée pénale des Lumières comme indistinctement humaniste, et ses adversaires comme unanimement hostiles à des vues utilitaristes. Les questions qui persistent dans la réfle…
