A comparative study on the compatibility of liquid lead–gold eutectic and liquid lead–bismuth eutectic with T91 and SS 316LN steels

2012

Abstract Liquid lead–gold eutectic (LGE) is considered as a potential target material for high power spallation sources. In the present work, the corrosion effects of LGE on T91 and SS 316LN steels have been investigated in comparison with that of liquid lead–bismuth eutectic (LBE) under the same testing conditions. Two tests were conducted at 400 °C for 1800 h and at 450 °C for 1300 h, in which specimens of the two steels were exposed to 1 m/s flowing LGE and LBE. Surface inspections showed that the specimens underwent a mixed corrosion mode of dissolution and oxidation. The results obtained from the SS 316LN specimens are very interesting. Firstly, EDX (electron energy dispersion X-ray sp…

Evaluation and comparison of trace metal accumulation in different tissues of potential bioindicator organisms: Macrobenthic filter feedersStyela pli…

2016

Trace metal concentrations were measured in different tissues of Sabella spallanzanii, Styela plicata, and Mytilus galloprovincialis collected in the Termini Imerese Harbor (Sicily, Italy) to evaluate the potential use of these species as bioindicators. Higher bioaccumulation factors (BAFs) were calculated in the tube of S. spallanzanii, except for As, which had a higher BAF in the branchial crown of the same species. Regarding the other species analyzed, higher BAFs were found in the digestive gland of M. galloprovincialis. An exception was Pb, which was significantly more concentrated in the branchial basket and tunic of S. plicata. The BAFs calculated in the present study show that all t…

The n_TOF facility: Neutron beams for challenging future measurements at CERN

2016

The CERN n TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron energies, from thermal to a few GeV. These characteristics provide a unique possibility to perform high-accuracy measurements of neutron-induced reaction cross-sections and angular distributions of interest for fundamental and applied Nuclear Physics. Since 2001, the n TOF Collaboration has collected a wealth of high quality nuclear data relevant for nuclear astrophysics, nuclear reactor technology, nuclear medicine, etc. The overall efficiency of the experimental prog…

Moment-Axial Domain of Corroded R.C. Columns

2018

In the present paper, a simplified model to determine the moment-axial force domain of the cross-section of reinforced concrete columns subjected to corrosion process is presented. The model considers members with square and rectangular cross-sections and it accounts for cover spalling, buckling of longitudinal reinforcing bars, loss of bond of bar in tension, reduction of confinement pressures (due to the reduction of the area of stirrups and cracking of concrete induced by rust formation). The analytical expressions for prediction of the area reduction of steel, bond strength and critical load of longitudinal bars utilized were verified against experimental data available literature.

Valutazione delle lesioni del tendine del sovraspinato con elastosonografia: confronto con ecografia B-mode e risonanza magnetica. Nostra esperienza.

2010

SCOPO: Valutare l'elasticità del tendine del sovraspinato in pazienti con sospetto clinico di lesione della cuffia dei rotatori, e comparare i reperti dell'elastosonografia con quelli dell'ecografia B-mode (US) e della risonanza magnetica (RM). DISEGNO DELLO STUDIO: Prospettico. MATERIALI E METODI: Nel periodo compreso tra agosto 2008 e settembre 2009, abbiamo valutato la spalla sintomatica di 20 pazienti con elastosonografia usando una sonda lineare da 13 MHz (EUB - Hitachi 7500, Giappone). E' stato usato uno score semiquantitativo di colori differenti rappresentanti tessuto più rigido (blu) e tessuto via via meno rigido (verde, giallo, rosso). I reperti sono stati comparati con quelli del…

Ettore Spalletti. Lo "spazio per creare" come "spazio della memoria"

2019

Una riflessione sul ruolo della memoria e dei luoghi nell'arte di Ettore Spalletti. Tra gli artisti italiani contemporanei, Ettore Spalletti è senza dubbio uno dei più conosciuti e celebrati al mondo. Nato a Cappelle sul Tavo, nell’entroterra pescarese, sin dagli inizi degli anni sessanta Spalletti sperimenta con intensità un’appassionante ricerca sulla pittura tonale e sulla forma scultorea essenziale. Un’indagine che affonda le proprie radici nella tradizione pittorica italiana – con particolare riferimento a quella appenninica e rinascimentale – e che risale il tempo della storia dell’arte passando per il Minimalismo artistico contemporaneo e l’arte Concettuale.

L'idrochinesiterapia nel recupero dell'arto superiore dopo allungamento dei flessori del gomito e asportazione di paraosteoartropatia di spalla in so…

2007

La spasticità, oltre a determinare alterazioni dei fisiologici schemi di movimento, siaccompagna a complicanze musoclo- scheletriche per le quali spesso si ricorre all'intervento chirurgico. La riabilitazione, partendo da un'accurata valutazione pre e postoperatoria del malato, da un lato mira al recupero e al mantenimento dell'articolarità, dall'altro al ripristino della motilità volontaria e della destrezza dei movimenti. L'idrochinesiterapia offre evidenti vantaggi nel trattamento di questi soggetti. In questo lavoro si espone la nostra esperienza su un paziente di 38 anni con esiti di trauma cranio-encefalico sottoposto dapprima ad intervento chirurgico sull'arto superiore ed in seguito…
