Études géoarchéologiques et archéobotaniques du comblement de la canalisation du site de la Rue du Ruisseau à Grand (Vosges, Lorraine, France)
2017
International audience; The ancient urban area of Grand (Vosges, Lorraine, France) is characterised by numerous hydraulic infrastructures including a canalisation, crossing the ‘Rue du Ruisseau’ site, which has been in the focus of multidisciplinary investigations. Stratigraphic study and characterisation (sedimentology and micromorphology) of sediments filling of this canalisation and of associated carbonated crusts show a succession of accumulation and erosive phases, driven by variations of the water level. Sequential stratigraphy allows the identification of gaps in the sedimentary sequence corresponding to cleanings and backfills of some sections of the canalisation. Combustion waste a…

The production of terracotta figurines in the city of Augustodunum. Presentation of the latest research.
2018
National audience; Les opérations archéologiques menées depuis 2013 sur le secteur de la Genetoye ont permis de mettre au jour un mobilier de coroplastie important et de bonne qualité. Ces figurines ont constitué le point de départ de la réalisation d’un mémoire universitaire (ANDROUIN 2017) et d’une nouvelle approche de ces objets. Nous présenterons ici les derniers résultats concernant l’étude des productions des figurines en terre cuite gallo-romaines dans l’agglomération d’Augustodunum.

Arte contemporanea e sistema dell’arte. Una breve ricognizione
2018
Il contributo prende in esame i principali soggetti del sistema dell’arte, come artisti, curatori, critici, collezionisti, gallerie, musei e fiere, analizzando la nascita del fenomeno in riferimento a protagonisti e movimenti di epoca contemporanea e offrendo spunti di riflessione sulle dinamiche che regolano tale network complesso e affascinate. The contribution explores the main players of the art system (artists, curators, critics, collectors, galleries, museums and art fairs) examining this phenomenon in reference to contemporary artists and movements and offering a reflection on the dynamics which regulate this complex and fascinating network.
Optimal Guard Placement Problem Under L-Visibility
2006
Two points a and b in the presence of polygonal obstacles are L-visible if the length of the shortest path avoiding obstacles is no more than L. For a given convex polygon Q, Gewali et al [4]. addressed the guard placement problem on the exterior boundary that will cover the maximum area exterior to the polygon under L-visibility. They proposed a linear time algorithm for some given value of L. When the length L is greater than half of the perimeter, they declared that problem as open. Here we address that open problem and present an algorithm whose time complexity is linear in number of vertices of the polygon.
A theoretical investigation on the Cd doping of Cu-depleted CuInSe<inf>2</inf> materials
2011
Because of their outstanding characteristics and affordable price, polycrystalline thin film solar cells based on CuIn 1−x Ga x Se 2 (CIGS) absorber layer have emerged to be one of the most promising materials for photovoltaic applications [1–2]. To further enhance the efficiency of these solar cells much effort is spent on the in-depth investigation of the production methods. However, the effect of structural defects and dopants upon the macroscopic properties and morphology of epitaxially grown CIGS films is not yet fully understood [3]. More importantly, it is well established that the best cells can be prepared by growing the CIGS absorber layer under Cu-poor conditions [4]. Thus, it is…
Muscarine receptor types mediating autoinhibition of acetylcholine release and sphincter contraction in the guinea-pig iris.
1990
The potencies of several muscarine receptor antagonists in blocking either the autoinhibition of acetylcholine release or the muscarinic contraction of the sphincter muscle upon acetylcholine release were investigated in the guinea-pig iris. The agonist at pre- or postjunctional muscarine receptors was acetylcholine released upon field stimulation (5.5 Hz, 2 min) of the irides preloaded with 14C-choline. The stimulation-evoked 14C-overflow was doubled in the presence of atropine 0.1 mumol/l but unaffected by the agonist (+/-)-methacholine (50 mumol/l). Thus, under the present stimulation conditions, the autoinhibition of acetylcholine release on the guinea-pig iris cholinergic nerves was ne…
Enterococcal meningitis caused by Enterococcus casseliflavus. First case report
2005
Abstract Background Enterococcal meningitis is an uncommon disease usually caused by Enterococcus faecalis and Enterococcus faecium and is associated with a high mortality rate. Enterococcus casseliflavus has been implicated in a wide variety of infections in humans, but never in meningitis. Case presentation A 77-year-old Italian female presented for evaluation of fever, stupor, diarrhea and vomiting of 3 days duration. There was no history of head injury nor of previous surgical procedures. She had been suffering from rheumatoid arthritis for 30 years, for which she was being treated with steroids and methotrexate. On admission, she was febrile, alert but not oriented to time and place. H…
