Patterning of Suitable Structures for the Investigation of the Josephson Effect in YBa2Cu3O7/PrBa2Cu3O7 Superlattices
1996
The aim of our work is to investigate the Josephson effect in YBa 2 Cu 3 O 7-δ /PrBa 2 Cu 3 O 7-δ superlattices. In the case of current flow along c axis direction the superlattice forms an array of artificial Josephson junctions where the YBa 2 Cu 3 O 7-δ layers are the superconducting electrodes which are separated but Josephson coupled by the PrBa 2 Cu 3 O 7-δ sheets. In this paper we report on the preparation, characterisation and patterning of the superlattices into suitable structures via standard photolithograpy and lift-off technique.
BEFORE THE EARTHQUAKE: RECONSTRUCTION AND PRESENTATION OF LOST SITES AND BUILDINGS
2021
Abstract. The paper presents the results of a research aiming at proving the efficacy of perspective restitution from photos for the reconstruction of buildings and sites that disappeared in the past century. The case study is the town of Messina, sited at the north-eastern corner of Sicily (Italy), facing the homonymous strait that divides Sicily from the Italian peninsula; in 1908 Messina and Reggio Calabria, at the opposite side of the strait, were levelled to the ground by a powerful earthquake, followed by a tsunami.No building or monument survived the destruction: a new town with the same name took the site of Messina. Except for few strongly reshaped buildings, the memory of the stre…
Una storia italiana: Giorgio e Isabella
2018
Si tratta, qui, della storia di due italiani dalla “pelle scura” raccontata, per Giorgio Marincola, da Carlo Costa e Lorenzo Teodonio in Razza partigiana e, per la sorella Isabella, da Wu Ming 2 e Antar Mohamed in Timira. Romanzo meticcio. Le loro vicende, così come molti altri aspetti della nostra storia coloniale, neocoloniale e postcoloniale, sono riemerse dal buio nel quale erano state occultate solo nell’ultimo quindicennio, grazie alla riapertura degli archivi che ha permesso di ridiscutere molti degli aspetti che nelle pagine di Storia, così come in quelle letterarie, erano stati raccontati in altro modo. I due testi, che hanno inevitabilmente finito per incontrarsi e che potremmo in…
Aportaciones documentales sobre cruces de orfebrería valencianas. Siglos XIV y XV
2020
The article intends to make a contribution of new documentary references, from the notarial funds of the Valencian archives, in which news about parish crosses and Lignum Crucis from the silversmith center of Valencia during the fourteenth and fifteenth centuries are collected. The importance of these typologies lies in being the main elements of Christian worship, so it was an essential piece in each parish that allowed the provision in them of models of varied typology and functionality; for that reason they are conserved from altar crosses, cross-shaped reliquaries ?known as Lignum Crucis or Veracruz ?to processional crosses, larger and representative of the parish community to which it …

Architetture nel cassetto
2017
Lo studio riguarda la lettura di due progetti mai realizzati di Gae Aulenti, del 1963 e del 1972, la Casa nel bosco e la Villa a Capalbio. Si vuole dimostrare che la ricostruzione congetturale attraverso i modelli digitali è un atto chiarificatore di alcuni aspetti dell’architettura demandati, spesso, soltanto alla parola scritta; attraverso la costruzione di inedite rappresentazioni le parole prendono forma attraverso un nuovo corpus figurativo; il modello digitale non è soltanto l’immagine virtuale dell’edificio ma esso assurge a immagine possibile diventandone la sua sola realtà esistenziale. The study concerns the reading of two unbuilt projects by Gae Aulenti, of 1963 and 1972, the Hou…
Caractérisation des tôles Fer-Silicium en régime dynamique pulsant
1992
Using a characterization method based on the Epstein's frame principle, we study the evolution of the magnetic and losses characteristics of NO Fe-Si sheets with respect to the fundamental frequency, the temperature and the wave front under time-variable sinusoidal or constant wave front trapezoidal magnetic flux density. At last, we modelise the evolution of the iron losses with respect to these parameters, except the temperature

French Higher Education Institutions (HEIs) are, for 89% of the respondents to the survey, now having their own open repository, or declaring to be in the implementation phase (compared to 82% in 2017 and only 62% in 2014). It can therefore be considered that almost all HEIs now offer a green open access repository or signalling solution to their researchers. The « still in progress » or suspended projects are rather related to the current recomposition of the Higher Education landscape. The most obvious obstacles to the latest implementations remain both the low involvement of researchers in the project and the human resources allocated. There is a slight but real increase in the rate of i…

The importance of dead seagrass (Posidonia oceanica)matte as a biogeochemical sink
2022
We assessed the potential of dead seagrass Posidonia oceanica matte to act as a biogeochemical sink and provide a coherent archive of environmental change in a degraded area of the Mediterranean Sea (Augusta Bay, Italy). Change in sediment properties (dry bulk density, grain size), concentration of elements (Corg, Cinorg, N, Hg) and stable isotope ratios (δ13C, δ 15N) with sediment depth were measured in dead P. oceanica matte and unvegetated (bare) sediments in the polluted area, and an adjacent P. oceanica meadow. Principal Component Analysis (PCA) revealed a clear clustering by habitat, which explained 72% of variability in our samples and was driven mainly by the accumulation of N and H…
