Valutazione di efficienze fotoelettriche per uno scintillatore LaBr3(Ce) tramite un approccio Virtual Point Detector
2019
L’impiego di uno scintillatore a Bromuro di Lantanio, LaBr3(Ce), come strumento di misura della attività (o concentrazione) in un dato campione, richiede la valutazione delle efficienze fotoelettriche o la conoscenza di una corrispondente curva di calibrazione. Oltre ai consueti metodi basati sull’impiego di sorgenti calibrate aventi la stessa forma e composizione del campione in esame, o metodi Monte Carlo, uno strumento rapido di valutazione delle efficienze può essere rappresentato dall'applicazione della semplificazione “Virtual Point Detector” (VPD), ovvero con il rilevatore assunto equivalente a un punto virtuale all’interno del cristallo dove si può considerare avvengano tutte le int…
A case study of a British ERASMUS student in Italy
2013
This article focuses on the shaping of social identities and emotions of one British young woman who spent a Year Abroad (YA) in Italy as an ERASMUS student. I have examined her negotiation and (re)construction of social identities during her experience abroad from a poststructuralist perspective, which sees individuals’ identities as dynamic and changeable sites of struggles (Norton Pierce, 1995 and 2000). In order to analyse the participant's accounts of her language learning and emotional experiences during her YA I have used the notion of emotional investment developed by Pavlenko (2012). This notion has helped me to understand how, why and to what extent the participant in the study ga…
Segregation in Drying Binary Colloidal Droplets
2019
When a colloidal suspension droplet evaporates from a solid surface, it leaves a characteristic deposit in the contact region. These deposits are common and important for many applications in printing, coating, or washing. By the use of superamphiphobic surfaces as a substrate, the contact area can be reduced so that evaporation is almost radially symmetric. While drying, the droplets maintain a nearly perfect spherical shape. Here, we exploit this phenomenon to fabricate supraparticles from bidisperse colloidal aqueous suspensions. The supraparticles have a core-shell morphology. The outer region is predominantly occupied by small colloids, forming a close-packed crystalline structure. Tow…
Trade-off Performance of Optical Nanoantennas for Solar Energy Harvesting Applications
2019
In this paper, the optimum behaviour of optical nanoantennas, in terms of impedance, directivity, available power, and field enhancement, at a resonance frequency of about 350 THz, will be shown. Optimum configurations are obtained by varying nanoantennas geometry in order to maximize the available power, enhancing the electric field in gap proximity and so the absorptivity. Moreover, the simulation results for aluminum nanoantennas on a three-layers substrate, will be reported, and a trade-off performance comparison among different antennas will be discussed. This study can guide both the engineering and the fabrication of plasmonic nanoantennas.
Aproximación al higienismo en la arquitectura de Rafael Guastavino
2021
La obra de Rafael Guastavino Moreno (1842-1908) está vinculada habitualmente a la construcción con bóveda tabicada, un sistema constructivo tradicional originario del Levante peninsular que este arquitecto combinó con el mortero de cemento para erigir un gran número de edificios de muy diverso tipo tanto en Barcelona como posteriormente en Estados Unidos. Sin embargo, estos autores han defendido en otras ocasiones la versatilidad de Guastavino como arquitecto y hasta qué punto la bóveda tabicada no supuso en un principio el cuaderno de bitácora único ni principal para su trayectoria profesional. La bóveda tabicada representó una herramienta más en la panoplia de sus habilidades, entre las c…

The effects of short-term sojourn experiences on adolescents : five narratives of adolescent Finnish students in a comenius project: EU & I
2012
Tutkimuksessani tarkastelen lyhytaikaisen ulkomailla oleskelun vaikutuksia viiteen suomalaiseen alakouluikäiseen oppilaaseen. Oppilaiden kokemukset karttuivat Comenius projektissa EU ja minä. Kaikki viisi haastateltua lasta olivat oppilaina samassa Pohjois-Pohjanmaalla sijaitsevassa koulussa, ja osallistuivat samoille kolmeen eri EU-maahan suuntautuneille opintomatkoille. Kaikki oppilaat matkustivat oppilasparin kanssa, ja kokivat samantyyppisiä tapahtumia. Neljä viidestä tutkimukseen osallistuneesta oppilaasta isännöi perheessään ulkomaalaista oppilasta, ja tutkin myös heidän mahdollisia positiivisia kokemuksiaan isännöinnistä. Tutkimukseni lähdekirjallisuutena ja vertailuaineistona käytän…
Di seta et oro. Antichi tessuti nelle chiese di Acireale
2021
This book dedicated to the ancient silk and gold fabrics of the church of Acireale in Sicily, is a text prepared by Fabio Francesco Grippaldi and Maurizio Vitella within the European project H2020 Silknow: Weaving our past into the future (European Union's Horizon 2020 research and innovation program under grant agreement No 769504). It presents a large collection of textile artefacts, largely unpublished, in use in the basilicas of Acireale. The sacred vestments analyzed both in the introductory essays and in the analytical sheets are contextualized in the broad panorama of reference, both national and European, and cover a chronological span that extends from the sixteenth to the twentiet…

Iniziative per la diffusione della lingua e della cultura italiana nella Cina pre-1949
2020
Until recently scholars who have examined the diffusion of the Italian language in China have focussed on the People’s Republic of China. However, we have proof of early teaching and cultural activities by Italian schools in China since the late 19th century. Most of them though were run by Catholic missions receiving financial support from the Italian government and initially they did not include language teaching, due to the locals’ lack of interest. The reason for this was to be found in the weak diplomatic, political and economic role played – particularly when compared with other foreign powers. This was clear to Italian diplomats – yet a real breakthrough for the popularization of Ita…
