Une vigne gallo-romaine de plaine à Gevrey-Chambertin (Côte-d'Or), Ier-IIe s. ap. J.-C.. Implications pour le développement des terroirs viticoles de…
2011
Recent excavations at Au-dessus de Bergis in Gevrey-Chambertin (Côte-d’Or, Burgundy) brought to light numerous, rectangular aligned pits interpreted as an ancient vineyard dated from the end of the 1st/mid-2nd century to the 3rd century AD. The vineyard is largely extent in area and was bounded to the south by a hedge or fence. It was composed of parallel rows that may have been trained over and along high, inclined wooden frames. Vine stocks were renewed by layering, over several generations of plants, according to some agricultural wine-growing techniques recommended by Latin agronomists. This vineyard attests to the establishment of vineyards from the mid-1st century AD in places differe…

INCIDENZA SULL’ANALISI DI RISCHIO DELLE MODALITÁ DI MISURA DEI SOIL GAS: IL CASO DI UN S.I.N. SICILIANO
2020
Il monitoraggio delle matrici aeriformi sta assumendo importanza crescente nell’ambito dei procedimenti di bonifica di siti contaminati, con riferimento sia all’esecuzione delle analisi di rischio, sia alla conseguente progettazione degli interventi di risanamento. L’utilizzo di misure dirette di campo si rivela di notevole interesse per la verifica di quelle indirette, ottenute con gli algoritmi implementati nei modelli matematici utilizzati per l’analisi di rischio. Obiettivo del lavoro presentato nella nota è stato quello di valutare l’influenza di misure dirette di soil gas e di flussi emissivi sull’analisi di rischio sanitaria. Come caso studio, si è considerato un S.I.N. nel territori…
Saint-Dizier « la Tuilerie » (Haute-Marne) : trois sépultures d’élite du VIe siècle
2019
In 2002, excavations carried out by Marie-Cécile Truc (Inrap) at Saint-Dizier led to the discovery of four graves of exceptional wealth, containing a young woman, two men and a horse, dated to c. 525-550 AD. Dressed and adorned with numerous jewels, the young female was laid in a coffin upon which were placed vessels in glass, copper alloy goblet and ceramic. Each male had been buried in an excavated funerary chamber, built within an oak frame. They were laid in their coffins along with their personal clothing, including a ceremonial sword with two rings added to the pommel. The larger weapons (throwing axes, shields, lances and angons) as well as various utensils were placed either on the …
The linguistic construction of confirmation niches in online comment sequences
2018
This study starts from the consideration that new media are platforms where communication and language are re-negotiated to adapt new frames (e.g. new politeness, multimodal exchanges) and, in particular, that fora are participatory frameworks, that represent a mined engagement in writing practices (Stommel and Koole, 2010). Discussions are organised as multiparty conversations on several topics, written by participants (i.e website users accessing a parenting forum) at different levels of expertise about health issues (mostly earned through their experience of parenthood; Kata, 2010). the challenge in this paper is : 1) to study asynchronous forum as a talk-in -interaction venue, where seq…
The XENON1T Dark Matter Experiment
2017
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented. © 2017, The Author(s).
XENON1T Dark Matter Data Analysis: Signal Reconstruction, Calibration and Event Selection
2019
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric $\mathrm{ton}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In pa…
La sépulture à char de La Tène A ancienne des “Craises” à Molinons (Yonne)
2013
The study reports on a chariot tomb excavated in 1985 at Les Craises in Molinons (Yonne). Set in an adventitious position in the midst of a monument with three quadrangular enclosures, the grave was of an adult of undetermined sex. Despite later pillaging, the goods found in this aristocratic tomb permit a dating to the second quarter of the 5th century BC, and an unusual cultural attribution, on the frontier in the Parisian Basin between the Jura culture to the south and the Marne-Moselle culture to the north.
Hydrothermal methane fluxes from the soil at Lakki plain (Nisyros Island, Greece)
2013
Μετρήσεις φυσικής ροής μεθανίου και διοξειδίου του άνθρακα από το έδαφος πραγματοποιήθηκαν με τη μέθοδο συγκέντρωσης θαλάμου στην περιοχή Λακκί της Καλδέρας της Νισύρου, καλύπτοντας έκταση περίπου 0.06 km2 συμπεριλαμβάνοντας τις περιοχές Καμινάκια, Στέφανος και Αλέξανδρο όπου παρατηρείται έντονη ατμιδική δραστηριότητας. Οι τιμές ροής που μετρήθηκαν σε 77 σημεία κυμαίνονται από –3.4 μέχρι 1420 mg m-2 d-1 για το CH4 και από 0.1, μέχρι 383 g m-2 d-1 για το CO2. Στις τρεις ατμιδικές περιοχές παρουσιάζονται διαφορετικοί ρυθμοί διαφυγής μεθανίου, ιδίως στα Καμινάκια όπου προέκυψαν οι μεγαλύτερες τιμές ροής. Η εξερχόμενη ποσότητα μεθανίου εκτιμάται σε 0.01 t a-1 από μια έκταση περίπου 2500 m2 στον…
