Rogliano – La Coscia
No full textLa campagne de fouilles à la grotte de la Coscia a connu des conditions météorologiques relativement favorables qui ont permis de poursuivre en parallèle la fouille à l’extérieur et dans la grotte. Les principaux résultats obtenus sont actuellement les suivants : À l’intérieur de la grotte : la fouille a été poursuivie dans les couches 5, 6 et 7 (stratigraphie 1994). De nouvelles traces de feu, très lessivées, ont été trouvées au sommet de la couche 7. À proximité d’un foyer lessivé ont été d..
On the Asymptotic Behavior of D-Solutions to the Displacement Problem of Linear Elastostatics in Exterior Domains
No full textWe study the asymptotic behavior of solutions with finite energy to the displacement problem of linear elastostatics in a three-dimensional exterior Lipschitz domain
Alpine Complex Landscape Environment
No full textNell'ambito del programma triennale Torino e le Alpi (2014/2016), la Compagnia di San Paolo ha promosso un Bando di ricerca applicata per lo sviluppo economico e sociale dei territori alpini di Piemonte, Liguria e Valle d'Aosta.Il bando ha inteso sostenere ricerche su politiche, modelli, progetti in Italia e all'estero e studiarne le condizioni per la trasferibilità/fattibilità in territorio montano, con soluzioni sperimentali, attraverso la selezione di buone pratiche, modelli operativi e idee originali, con forte carattere innovativo. Dei 153 progetti presentati 20 sono stati vincitori e finanziati tra cui La ricerca Alpine Landscape Environment (referente e coordinatore scientifico Daniele Regis) . La pubblicazione contiene l'abstract dei progetti presentati con link del report completo. La ricerca Alpine Cle ha inteso costituire un sistema transdisciplinare come modello per un'applicazione puntuale degli indirizzi del piano paesistico regionale Le discipline della Progettazione del paesaggio e architettonica (D. Regis) della cartografia e GIS (N. Spano) della valutazione economica dei progetti (C. Coscia) sono state interpellate attraverso processi congiunti di analisi per costruire scenari disviluppo sostenibile in particolare per la mobilità e infrastrutture per lo sviluppo con innovativi metodi di ricerca scientifica e modelli ad alta trasferibilità

No full textModelli matematici del traffico veicolare - Istituto Nazionale di Alta Matematica
No full textIl progetto è stato finanziato a seguito ad un bando competitivo dell'Istituto Nazionale di Alta Matematica. Scopo del progetto è stata l'identificazione e l'analisi di modelli matematici del traffico veicolare a diverse scale di osservazione e in diversi frameworks analitici e computazionali. Esso ha visto il coinvolgimento di diverse sedi universitarie (Ferrara, Torino-Politecnico, Bologna, Perugia, Roma-La Sapienza, Palermo) e circa una ventina di ricercatori. Nell'ambito del progetto è stato organizzato a Ferrara, nei giorni 8-9 Maggio 2003, un workshop internazionale su “Mathematical Models and Methods in the Study of Traffic Flow”. Il workshop, che ha ospitato due keynote lectures da parte di D. Helbing, ora al Politecnico di Zurigo, e di M. Rascle dell'Università di Nizza, ha visto la partecipazione di numerosi studiosi, provenienti sia dall'ambito matematico che ingegneristico. Nell'ambito del progetto sono stati prodotti diversi lavori usciti a stampa
Étude préliminaire des restes de cervidés de la grotte de la Coscia (Rogliano, Haute-Corse)/A Preliminary study of cervid remains from the grotte de la Coscia (Rogliano, Haute-Corse)
No full textA Preliminary study of cervid remains from the grotte de la Coscia (Rogliano, Haute-Corse). Excavations conducted since 1994 in the Cosicia cave have yielded abundant Upper Pleistocene endemic deer remains that are attributed to Megaceros (Nesoleipoceros) cazioti. These deer remains are mainly concentrated in level D where they represent the majority of the fauna recovered. Anatomic and biometric comparisons with Sardinian deer populations permit us to imagine a complex evolutionary history which likely occurred in different ways in Corsica and Sardinia.Les fouilles conduites depuis 1994 dans la grotte de la Coscia (Rogliano/Haute-Corse) ont livré de très nombreux restes de Cervidés datés du Pléistocène supérieur et rapportés à l'espèce insulaire Megaceros (Nesoleipoceros) cazioti. Ces ossements sont relativement abondants dans la structure D où ils représentent la majorité de la faune exhumée. Les comparaisons anatomiques et biométriques avec les populations sardes permettent d'imaginer une histoire évolutive complexe qui s'est probablement déroulée de façon différente en Corse et en Sardaigne.Pereira Elisabeth, Bonifay Marie-Françoise.

Room temperature visibile photoluminescence of silicon nanocrystallites embedded in amorphous silicon carbide matrix
No full textThe nanocrystalline silicon embedded in amorphous silicon carbide matrix was prepared by varying rf power in high vacuum plasma enhanced chemical vapor deposition system using silane methane gas mixture highly diluted in hydrogen. In this paper, we have studied the evolution of the structural, optical, and electrical properties of this material as a function of rf power. We have observed visible photoluminescence at room temperature and also have discussed the role played by the Si nanocrystallites and the amorphous silicon carbide matrix. The decrease of the nanocrystalline size, responsible for quantum confinement effect, facilitated by the amorphous silicon carbide matrix, is shown to be the primary cause for the increase in the PL intensity, blueshift of the PL peak position, decrease of the PL width (full width at half maximum) as well as the increase of the optical band gap and the decrease of the dark conductivity
Enthesitis of the direct tendon of the rectus femoris muscle in a professional volleyball player: A case report
No full textEnthesitis of the direct tendon of the rectus femoris muscle is a rare pathology which mainly affects professional athletes, and it is caused by overuse and repetitive microtrauma. Athletic jumping and kicking exert a great stress on the direct tendon of the rectus femoris muscle, and volleyball and football players are therefore most frequently affected. Enthesitis may occur suddenly causing pain and functional impairment possibly associated with partial or complete tendon injuries, or it may be a chronic condition causing non-specific clinical symptoms.We present the case of a professional volleyball player who felt a sudden pain in the left side of the groin area during a training session although she had suffered no accidental injury. The pain was associated with impaired ipsilateral limb function. Tendon rupture was suspected, and magnetic resonance imaging (MRI) was performed. MRI showed a lesion at the myotendinous junction associated with marked inhomogeneity of the direct tendon. Ultrasound (US) examination confirmed the presence of both lesions and allowed a more detailed study of the pathology. This is a typical case of enthesitis which confirms that MRI should be considered the examination of choice in hip pain, particularly when the patient is a professional athlete, thanks to its panoramic visualization. However, also US is an ideal imaging technique for evaluating tendon injuries thanks to its high spatial resolution, and it can therefore be used effectively as a second line of investigation. © 2011 Elsevier Srl
