Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
Trapped? Exploring the lives of young women in France and England who are labelled NEET and economically inactive
2021
International audience; Through a comparison of France and the UK, this paper analyses the position of young women who are defined as not in education, employment or training (NEET) and economically inactive (EI). Little is known about the NEET EI group and how this status shapes young people’s lives during school-to-work transition. Consequently, the NEET EI group remains a ‘hidden’ problem in many countries and impacts to a much greater extent on young women, due to their propensity to assume caring responsibilities. Despite France and the UK having very different types of policy intervention and welfare support, there are similarities between them in terms of NEET EI populations and the …
Experimental investigation on the efficiency of zinc(II) recovery from waste streams by TBP liquid-liquid extraction
2016
In many industrial processes the presence of zinc in the wastewater may represent an obstacle to its high efficient regeneration. This is the case of the treatment of spent pickling solutions aiming the recovery of hydrochloric acid via pyrohydrolysis techniques. Hydrochloric spent pickling solutions from steel processing contain relevant amount of metals such as iron (Fe) and zinc (Zn) that may significantly affect recovery of hydrochloric acid (HCl) through pyrohydrolysis. In fact, although Fe may be recovered as ferric oxide (Fe2O3) and does not have a substantial effect on pyrohydrolysis process, zinc chloride (ZnCl2) evaporating can occlude nozzles and stick to the pyrohydrolysis react…
Recovering of zinc(II) from spent pickling solutions by liquid-liquid extraction
2015
Hydrochloric acid can be successfully recovered from spent pickling liquors with high efficiencies via pyrohydrolysis techniques. In the pickling solution feed, other metallic ions are typically present besides iron (mainly Fe2+) such as zinc(II). In order to avoid undesirable effects, zinc(II) has to be removed, because zinc chloride evaporates and sticks to the reactor walls, as well as it contaminates iron oxides product1. Moreover, zinc recovery is economically affordable because it allows the marketing of some products such as ZnCl2 and ZnSO4. In the present work, liquid-liquid extraction process has been selected to recover zinc(II) from pickling liquors, using suitable extractant age…
La posizione del terzo nel diritto delle obbligazioni. Uno studio evolutivo-comparato dal diritto romano ai più recenti strumenti di tutela, con part…
Lʼindividuazione di un filo conduttore che possa aiutare ad individuare lo sviluppo e i processi storici che hanno interessato la tutela e la protezione del terzo, a partire dal modo in cui il problema ha trovato configurazione in diritto romano, ammesso che si possa riconoscere che ne abbia escogitata una, sino allʼattuale profilarsi delle questioni teorico-dogmatiche sul punto, se da un lato appare senza dubbio come un problema stimolante e ricco di spunti, dallʼaltro si presta senza dubbio a concretizzare quei problemi e quei dubbi a cui si è appena fatto riferimento. Consapevoli di questo genere di dilemmi, nellʼaffrontare lʼargomento in oggetto si è quindi cercato di adottare un metodo…

Adaptation of French society to aging : aging today in an Age-Friendly City : integration, discrimination and roles of public policy
2019
This PhD work aims to analyse the way French cities seize and implement the Agefriendly Cities approach on their territories. Thanks to seventy semi-guided interviews, a second data analysis and active observation, we studied how thirteen French cities decided to implement the Age-friendly Cities approach.This work of research revolves around ideas about how to combat ageism, about the importance of consulting the inhabitants and of using a cross-disciplinary way of work. Like that, it aims to analyse how French cities adapted their local public policies in coherence with the frame given by the Age-friendly Cities approach, the national policies and the recommendations of the international …
Évaluation d'un Programme de Réussite Éducative
2010
Rapport, commandité par le Grand Dijon; Ce rapport rend compte de l'évaluation des projets de réussite éducative de l'agglomération dijonnaise. La première partie vise à cerner les enjeux de la réussite éducative et présente les grandes lignes de la démarche d'évaluation. La seconde partie s'attache à décrire le contexte d'intervention du projet sur les territoires en termes de public et d'actions. La troisième partie traite de l'efficacité du projet dans ses différentes dimensions. En conclusion, les pistes de réflexion les plus pertinentes sont dégagées sur la base de l'ensemble des analyses produites lors de cette évaluation.
