Le sanctuaire laténien de Semoine, « Voie Palon » (Aube)
2012
A rescue excavation in 2003 resulted in the discovery of a building on piles, constructed between two sections of ditch, of which the one on the north side has an entrance. The chronological data of the building and two ditches match and demonstrate the existence of cults during La Tène C2. Evidence of the cults is given by a small quantity of deliberately mutilated weapons, as has been found in other La Tène sanctuaries. Dating the creation of the enclosure is problematicaln but it probably derives from La Tène C1. Although sections of the site remained unexcavated, the stratigraphy of the ditches reveals the brevity and limited and unusual nature of the practices. This study links them to…
Le cimetière du second Âge du fer de la Tournière à Lailly (Yonne) : nouvelle analyse des fouilles anciennes
2021
International audience; Cette étude présente de manière critique les découvertes qui ont été faites à la fin du xix e siècle et au début du xx e siècle à Lailly La Tournerie (Yonne). Elle propose un classement typologique et chronologique de tous les objets mis au jour par catégorie fonctionnelle, ainsi que la reconstitution, pour la première fois, de plusieurs ensembles clos. Elle a ainsi permis de proposer une évolution de ce cimetière entre le second quart du v e siècle (La Tène A ancienne) et la première décennie du ii e siècle avant J.-C. (La Tène C1). L'analyse des pratiques funéraires a également été abordée à l'aide d'un dépouillement systématique des rares données existantes. Leur …
“Linearity, an English Trait?”
2009
This article looks at how the « English line” became one of the defining features of Englishness from the 1920s to the 1950s. It is based on texts by Michael Ayrton, Robin Ironside, John Piper and Nikolaus Pevsner that were published during or just after the Second World War, and that contributed to a contemporary critical reassessment of English art.
Haematological deficiencies in patients with recurrent aphthosis
2010
Background Recurrent aphthosis is a common oral ulcerative condition consisting also of a subset of similar ulcers, properly named 'aphthous-like' ulcers (ALU), linked to systemic diseases and among these, to iron, folic acid and vitamin B(12) deficiencies. Objectives The main objectives of this study were: (i) to evaluate the association between recurrent aphthosis and the most common predisposing factors; (ii) to assess the frequency of ALU in recurrent aphthosis; (iii) to verify the efficacy of a replacement therapy in all ALU patients. Methods Thirty-two adults with recurrent aphthosis and 29 otherwise healthy controls were consecutively recruited, interviewed and subjected to haematolo…
An SVM Ensamble Approach to Detect Irony and Stereotype Spreaders on Twitter
2022
The problem we address in this work is classifying whether a Twitter user has spread Irony and Stereotype or not. We used a text vectorization layer to generate Bag-Of-Words sequences. Then such sequences are passed to three different text classifiers (Decision Tree, Convolutional Neural Network, Naive Bayes). Our final classifier is an SVM. To test and validate our approach we used the dataset provided for the author profiling task organized by PAN@CLEF 2022. Our team (missino) submitted the predictions on the provided test set to participate at the shared task. Over several cross fold validation our approach was able to reach a maximum binary accuracy on the best validation split equal to…
«INTELLIGENTE, IRONICA». OLTRE IL MATRIARCATO, LA DONNA IN ALCUNE OPERE DI LEONARDO SCIASCIA
2021
Intelligente e ironica. Così appare al pittore protagonista del romanzo Todo modo la donna che lascia il marito nello spiazzale antistante L’Eremo di Zafer. Il tempo di uno sguardo, di una breve sequenza. Tuttavia il suo rilievo espressivo travalica la pagina per andare, insieme a tanti piccoli tasselli narrativi di altri racconti, a comporre un’inedita rappresentazione del personaggio femminile. E ciò assume un significato particolare se facciamo attenzione per un momento alle date, se consideriamo per esempio che l’anno di pubblicazione di Todo modo è lo stesso 1974 in cui lo scrittore rilascia la famosa intervista a Franca Leosini che tanto scandalo ha suscitato soprattutto fra le fem…
Use of Super Paramagnetic Iron Oxide Nanoparticles as Drug Carriers in Brain and Ear: State of the Art and Challenges
2021
International audience; Drug delivery and distribution in the central nervous system (CNS) and the inner ear represent a challenge for the medical and scientific world, especially because of the blood–brain and the blood–perilymph barriers. Solutions are being studied to circumvent or to facilitate drug diffusion across these structures. Using superparamagnetic iron oxide nanoparticles (SPIONs), which can be coated to change their properties and ensure biocompatibility, represents a promising tool as a drug carrier. They can act as nanocarriers and can be driven with precision by magnetic forces. The aim of this study was to systematically review the use of SPIONs in the CNS and the inner e…
Fast and continuous synthesis of nanostructured iron spinel in supercritical water: influence of cations and citrates
2014
International audience; Spinel iron oxide nanoparticles were obtained under supercritical water conditions in a continuous and fast (less than 10s) way by modifying the initial stoichiometric Fe II /Fe III molar ratio from (1/2) to (3/0), without base solution, and using citrates directly with iron precursors. This result opens the way of an economical and environmentally benign approach to synthesize superparamagnetic iron oxide nanoparticles (SPIONs) in important yields.
Cementing agents involved in the macro- and microaggregation of a Mediterranean shrubland soil under laboratory heating
2014
The heating effect on aggregation and cementing agents of a Mediterranean soil was studied in two fractions (macro- and microaggregates) in different environments: under Quercus coccifera soil (UQ), under Rosmarinus officinalis soil (UR) and between plants or bare soil (BS). Samples were heated under laboratory conditions at different temperatures (220, 380, 500, 750 and 1000. °C) to establish their effects on the studied soil properties by comparison with unheated control samples (25. °C). Increasing temperature treatments caused significant changes in most soil variables. In both soil fractions, the presence of vegetation contributed to increase of the soil organic matter (SOM) content, w…
