Radiation damage in the target area shielding of a facility for Selective Production of Exotic Species ( SPES Project )
The advancement of radioactive ion beam (RIB) science since its advent in the last few decades calls for the development of so-called next generation facilities, able to provide beam intensities several orders of magnitude higher than presently available. Two of them are planned by the European roadmap and are representative of the two main methods by means of which RIBs are produced nowadays: projectile fragmentation and isotope separation on-line (ISOL); the latter, based on the ISOL technique, is the EURISOL project: the plan encompasses the construction of three intermediate facilities, one of which is expected to be built at Legnaro (Padua) INFN Laboratories: the SPES Project (Selective Production of Exotic Species).
Gamma radiation damage of structural concrete immersed in water.
AbstractConcern for the integrity of the Materials Testing Reactor canal walls prompted the testing of structural concrete samples for damage due to intense and prolonged gamma radiation exposures. Testing of the samples by breaking them under compression following gamma exposures up to 2 × 1011 R i
Fortune and Responsibility in Calderón's La gran Cenobia
La gran Cenobia deals with the war between Queen Zenobia of Palmyra and the Emperor Aurelian. Calderón de la Barca draws most of his information from historical sources; the dramatist, however, changes history and adapts it to his own dramatic purpose. The theme of Fortune gives unity to the play. Aureliano is portrayed as a tyrant who, to prove his independence from Fortune, behaves tyrannically, causing his eventual downfall. Cenobia believes that Fortune controls her life, but does not acknowledge that her own actions contribute to her misfortune. The analysis concludes that Fortune, as depicted in this play, is not an omnipotent and blind force, but what one has forged with his or her own actions coupled with the actions of others and circumstance.
