Effects of underground silo storage on long-term grain preservation: 10 years of experiment
No full textInternational audienceFindings of charred seeds in archaeological silos are quite common, raising the question of their origin: remnants of burnt-in-place stocks or waste discharged into the structure? The discovery of large silo areas in medieval Mediterranean France delivering archaeological seeds, has revived questions about silage practices, how these structures functioned and their role in past societies. In this sense, the SilArchaeoBio project is carrying out an archaeological and archaeobotanical experimental research, conducted in southern France. It relies on the creation ex nihilo of 2 new functional silos areas, used since 2015. This work aims to address various issues: management and evolution of plant stocks and of the structures through time and taphonomy of the filling. Regarding the archaeobotanical approach, the research consists of documenting several parameters: effect(s) of silo storage on the preservation/degradation of ensiled remains, role of crop processing on the quality of seed conservation, role and advantages of mixed storage, effect of humidity on the stock, chances of stock preservation when the silo is cleaned by fire, etc. The final results of the projects obtained on stored Triticum monococcum, Triticum aestivum and Hordeum vulgare grains are encouraging: they present modes of conversation not described in the ethnographic literature and make it possible to start rethink the way of interpreting the archaeological seeds encountered in archaeological silos
Integration of the evaporable spin-crossover complex [Fe(HB(1,2,4-triazol-1-yl) 3 ) 2 ] into organic field-effect transistors: towards multifunctional OFET devices
No full textInternational audienceIntegrating stimuli-responsive molecular switches into organic electronic devices opens interesting perspectives to achieve unprecedented functionalities. However, significant challenges arise in maintaining device functionalities and ensuring synergy with the molecular properties. Here, we described three different ways of incorporating thin films of the molecular spin crossover (SCO) complex [Fe(HB(1,2,4-triazol-1-yl)3)2] into an organic field-effect transistor (OFET) device. The fabrication of high-quality films was enabled by the use of vacuum thermal evaporation, which permitted the deposition of the SCO compound either on the surface of the organic semiconductor or at the semiconductor/dielectric interface. In device configurations where the SCO layer was not in contact with the conduction channel, changes in the drain-source current were observed near the spin crossover temperature, suggesting a potential synergistic effect. These results provide valuable guidance for the design and integration of bistable-material-based functional devices
Arterial and venous flow dynamics are modified by age in the non-human primate
No full textInternational audienceGrowing evidence suggests that vascular abnormalities contribute to neurodegenerative processes during ageing. With the anticipated rise in the elderly population, we aimed to characterise arterial and venous flow dynamics, which reflect cardio-cerebro-vascular conditions, using a preclinical model: the marmoset monkey. We employed MRI protocols to image brain and intracranial vessel anatomy. We adapted the phase-contrast MRI protocol to measure blood dynamics synchronised with the ECG signal in the carotid arteries, basilar trunk, superior sagittal, and straight sinuses. We imaged both young and old healthy marmosets. Our analysis revealed a similar chronological sequence of maximal blood flow values in the various arteries and sinuses for both young and old marmosets; however, the peaks occurred earlier in the cardiac cycle for the older group. Furthermore, we observed shorter arterio-venous delays in older marmosets, suggesting ageing-related cardiovascular and cerebrovascular changes. We analysed the temporal progression of arterial and venous blood volumes within the cranial system at the cardiac cycle scale, providing valuable insights into the constraints on the craniospinal system. An illustration of the relationships between input flow and output flow revealed a characteristic hysteresis effect, indicating an age-dependent behaviour of the venous system
Technologie des capteurs de gaz à semi-conducteurs
No full textGas microsensors are of great industrial interest due to their small size, low consumption, low cost and therefore deployable in a distributed network. Semiconductor gas sensors, although having limited performance compared to analyzers, are among the most commercialized sensors along with electrochemical and optical sensors.This article covers the operation of these sensors, the main materials used (metal oxides) with their detection mechanism as well as the design, manufacturing, characterization and calibration techniques. Current avenues of research around electronic noses and associated perspectives are also discussed.Les microcapteurs de gaz ont un très gros intérêt industriel de par leur faible encombrement, leur faible consommation, leur faible coût, ce qui permet de les déployer en réseau distribué. Les capteurs de gaz à oxydes métalliques semiconducteurs, bien qu’ayant des performances limitées par rapport à des analyseurs, font partie des capteurs les plus commercialisés avec les capteurs électrochimiques et optiques.Cet article couvre le fonctionnement de ces capteurs, les principaux matériaux utilisés avec leur mécanisme de détection, ainsi que les techniques de conception, de fabrication, de caractérisation et d'étalonnage. Sont également abordées les pistes de recherche actuelles autour des nez électroniques, ainsi que les perspectives associées

Consumo digitale di film oltre i quadri legali: una nuova forma di cinefilia? Indagine empirica sull’accesso non autorizzato ai film (2001‑2012)
No full textInternational audienceDieser Beitrag untersucht die Cinephilie von Filmdownloadern zwischen dem Ende der Napster‑Ära – dem ersten von US‑Behörden 2001 geschlossenen Peer‑to‑Peer‑Netzwerk – und der Schließung von MegaUpload durch neuseeländische Behörden im Jahr 2012. In diesem Jahrzehnt verschwinden die technischen Hürden, die den Transfer großer Dateien lange behinderten, schrittweise, parallel zur Verbreitung von ADSL und dem Aufstieg des Streamings. Studien, die Download und Streaming aus konsumsoziologischer Perspektive betrachten, sind rar, obwohl diese Aneignungspraktiken Aufschluss über die Entwicklung cinephiler Geschmackspräferenzen geben. Auf Grundlage einer qualitativen Untersuchung analysieren wir die zugrunde liegenden Motivationen und verknüpfen sie mit dem Aufkommen neuer cinephiler Haltungen – jener der „Nische“ und der „Rarität“. Heute lassen alle Indikatoren darauf schließen, dass das Herunterladen von Filmen als verbreitetes Bildaneignungsverfahren etabliert ist und sich kaum von anderen im Kinosaal gelebten Formen der Cinephilie unterscheidet.This article examines the cinephilia of film downloaders between the end of the Napster era (the first P2P network shut down by US authorities in 2001) and that of MegaUpload, shut down in 2012 by New Zealand authorities. This decade has been characterized by the gradual disappearance of the technological barriers that have long hampered the downloading of large files, in tandem with the spread of ADSL and the rise of streaming . Few studies, however, have looked at downloading and streaming from the perspective of the sociology of consumption, considering these content appropriation practices as a means of determining a trend in cinephiles' taste for the cinema object. On the basis of a qualitative survey, we look at the motivations behind downloading and streaming, relating them to the emergence of new cinephilic behaviours ("niche" and "rarity" cinephilias). Today, these indicators converge to suggest that downloading or streaming films is a way of appropriating images that has become commonplace, with few differences from other uses of cinephilia consumed on the big screen.Este artículo analiza la cinefilia de quienes descargan películas entre el final de la era Napster —primera red P2P clausurada por las autoridades estadounidenses en 2001— y la cierre de MegaUpload por parte de las autoridades neozelandesas en 2012. Durante esa década, las barreras técnicas que obstaculizaban el traslado de archivos voluminosos se desvanecen gradualmente, de la mano de la generalización del ADSL y el auge del streaming. Son escasos los estudios que abordan descarga y streaming desde la sociología del consumo, aunque estas prácticas de apropiación permiten rastrear la evolución del gusto cinéfilo. A partir de una investigación cualitativa examinamos las motivaciones que las sustentan y las relacionamos con la aparición de nuevas posturas cinéfilas —las de la «nicho» y la «rareza». Hoy, todos los indicios convergen: descargar películas se ha convertido en un modo ya normalizado de apropiación de imágenes, con escasas diferencias respecto de otras formas de cinefilia cultivadas en la gran pantalla.Cet article explore la cinéphilie des téléchargeurs de films entre la fin de l’ère Napster — premier réseau pair‑à‑pair démantelé par les autorités américaines en 2001 — et celle de MegaUpload, fermé en 2012 par les autorités néo‑zélandaises. Durant cette décennie, les obstacles techniques qui freinaient le transfert de fichiers volumineux s’effacent progressivement, au rythme de la généralisation de l’ADSL et de l’essor du streaming. Les recherches abordant téléchargement et streaming sous l’angle de la sociologie de la consommation restent rares ; or ces pratiques d’appropriation permettent de saisir l’évolution du goût cinéphile. À partir d’une enquête qualitative, nous analysons les motivations qui structurent ces usages et les relions à l’émergence de nouvelles postures cinéphiles — celles de la « niche » et de la « rareté ». Aujourd’hui, l’ensemble des indices converge : le téléchargement et le streaming se sont banalisés comme mode d’appropriation des images, sans réel écart avec les autres formes de cinéphilie pratiquées en salle.Il presente articolo esamina la cinefilia dei downloader di film tra la fine dell’era Napster – prima rete peer‑to‑peer chiusa dalle autorità statunitensi nel 2001 – e la chiusura di MegaUpload da parte delle autorità neozelandesi nel 2012. In tale decennio i vincoli tecnici che ostacolavano il trasferimento di file di grandi dimensioni vengono progressivamente meno, parallelamente alla diffusione dell’ADSL e all’ascesa dello streaming. Poche ricerche hanno affrontato download e streaming dal versante della sociologia dei consumi, nonostante tali pratiche di appropriazione permettano di cogliere l’evoluzione del gusto cinefilo. Basandoci su un’indagine qualitativa analizziamo le motivazioni che strutturano questi usi e le colleghiamo all’emergere di nuove posture cinefile – quelle della “nicchia” e della “rarità”. Oggi gli indizi convergono: il download di film si è normalizzato come modalità di appropriazione delle immagini, senza sensibili differenze rispetto alle altre forme di cinefilia praticate in sala
