Distillation and stripping pilot plants for the JUNO neutrino detector: Design, operations and reliability
2019
Abstract This paper describes the design, construction principles and operations of the distillation and stripping pilot plants tested at the Daya Bay Neutrino Laboratory, with the perspective to adapt these processes, system cleanliness and leak-tightness standards to the final full scale plants to be used for the purification of the liquid scintillator of the JUNO neutrino detector. The main goal of these plants is to remove radio impurities from the liquid scintillator while increasing its optical attenuation length. Purification of liquid scintillator will be performed with a system combining alumina oxide, distillation, water extraction and steam (or N 2 gas) stripping. Such a combined…
Investigation of applicability of alanine pellets and films for dosimetry of proton clinical beams
2015
Laser-driven proton has recently gained a great interest as an alternative to conventional and more expensive acceleration techniques. These ion beams have desirable qualities such as small source size, high luminosity and small emittance to be used in different physics fields. This is very promising specially for the future perspective of a new concept of hadrontherapy based on laser-based devices could be developed, replacing traditional accelerating machines. ELIMED (Medical Applications at Extreme Light Infrastructure) is a task-force originally born by an idea of ELI-Beams (Prague) and INFN-LNS (Italian Institute for Nuclear Physics of Catania) researchers. ELIMED main goal is to perfo…

LE MISURE E LE AZIONI PER IL LAVORO IN SICILIA
2019
Di mestiere faccio lo statistico e so che la matematica non è neutra e che i numeri raccontano storie che si trasformano in responsabilità. Una di queste è di scoprire il velo che copre ogni dato, capire cioè cosa nasconde e rivelarlo. Il numero crescente di turisti in Sicilia, ad esempio, di per sé potrebbe indurre a ben sperare sulla crescita del settore turistico nella regione. Ma la responsabilità su questa storia evidenziata da questo dato ci impone di capire se e quanti sono realmente soddisfatti, se e quanti oltre al clima, al cibo e alle bellezze naturali, hanno apprezzato infrastrutture, trasporti, strutture ricettive, professionalità degli operatori, a tal punto da indurre a ritor…

Metabolic adaptations in neonatal mother-deprived rabbits
2010
[EN] In order to study the metabolic adaptation in response to 48 h transient doe-litter separation (DLS) in young rabbits (5 rabbits/d group) between postnatal 9 and 11 d, plasma concentrations of thyroid hormones T3 and T4, insulin, leptin, glucose, triglycerides (TG), and free fatty acids (FFA) were examined before (6-8 d), during (9-11 d), and after separation (12-16 d). T3 concentrations in newborn control rabbits gradually increased from 0.6 ng/mL at postnatal 6 d to 1.0 ng/mL at postnatal 16 d, whereas those of T4 remained fairly constant (25 ng/mL) up to postnatal 14 d, when T4 gradually declined to 8 ng/mL. T3 values of DLS newborn rabbits did not differ from those of controls at p…
L’isola delle città felici : riflessi d’Europa nella letteratura politica siciliana (secoli XVII-XIX)
2012
Il saggio ricostruisce il tema della felicità pubblica nella letteratura politica siciliana, mettendo in risalto l'originalità con cui soprattutto nelle opere poco note o cadute in oblio è trattato e proposto rispetto alle principali concezioni europee che si diffondono e circolano tra i secoli XVII-XIX.
Environmental noise and nonlinear relaxation in biological systems
2009
We investigate the role of the environmental noise in three biological systems: (i) an ecosystem described by a Verhulst model with a multiplicative Lévy noise; (ii) polymer translocation, and (ii) individuals of Nezara viridula. Specifically the transient dynamics of the Verhulst model perturbed by arbitrary non-Gaussian white noise is investigated as a first biological system. For Cauchy stable noise, exact results for the probability distribution of the population density and nonlinear relaxation are derived. We find a transition induced by the multiplicative Lévy noise, from a trimodal probability distribution to a bimodal probability distribution in asymptotics, and a nonmonotonic beha…
