Prior test experience produces changes of t-patterns spatial distribution in the elevated plus maze test
2014
Aim of present research was to investigate in male Wistar rats whether a prior elevated plus maze experience modifies the temporal structure of the behavioral response following a retest applied after 24h. Video files were coded by means of a software coder and event log files generated for each subject were analyzed by means of a specific software for temporal pattern analysis (Theme). Present research shows a clear reduction of the number of t-patterns from trial one to trial two. This reduction is provoked by the disappearance of t-patterns consisting of behavioral elements occurring in the unprotected zones of the maze. The results suggest that the previous experience in the maze causes…
Isolamento sismico di un serbatoio a Priolo Gargallo (SR)
2007
The paper relates the operations made for the seismic isolation of a tank located in Priolo Gargallo, in the Siracusa industrial area. The tank, built during the end of the seventies, is formed by a cylindrical steel shell, filled by a low temperature liquid, rested on a concrete slab, embedded on 139 columns, fitted together with the same number of foundation piles driven in the soil for about 12 meters. The friction pendulum bearing seismic devices have been adopted, installed in the superior part of the columns through the cut of a small section of the same. The intervention foresees the execution of a concrete slab at grade level, which has the functions to link all the pile heads, to f…
Temporal Patterns of Rodent Behavior in the Elevated Plus Maze Test
2012
The aim of the present study was to evaluate, by means of a temporal pattern analysis, rat’s behavior in the elevated plus maze test. A specific software called THEME has been used. On the basis of an ethogram encompassing 24 behavioral elements, results demonstrated that 14 components represented the 98% of the displayed activities. 145 different temporal patterns have been detected; length distribution of such patterns showed that three-, four-, and five-elements patterns were more represented than two-elements ones. Finally, a complex temporal pattern encompassing 8 behavioral elements has been discussed. Present article demonstrated the presence of complex temporal patterns characterizi…

The LOFT mission concept: a status update
2016
The Large Observatory For x-ray Timing (LOFT) is a mission concept which was proposed to ESA as M3 and M4 candidate in the framework of the Cosmic Vision 2015-2025 program. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument and the uniquely large field of view of its wide field monitor, LOFT will be able to study the behaviour of matter in extreme conditions such as the strong gravitational field in the innermost regions close to black holes and neutron stars and the supra-nuclear densities in the interiors of neutron stars. The science payload is based on a Large Area Detector (LAD, >8m2 effective area, 2-30 keV, 240 eV spectral resolut…
