No full textIl saggio, a partire dal progetto di ristrutturazione e ampliamento delle cascine comunali di Casalgrasso (Cuneo, Bruna & Mellano architetti associati, 1998/2996), propone di recuperare la memoria del passato per conservare l'identità dell'architettura italiana, la cultura della città, ovvero la "quinta dimensione" dell'architettura
Control of bulk superconductivity by surface charge doping in a BCS superconductor
No full textWe investigate the effects of pure charge doping (obtained by using the so-called electric-double layer gating technique) in thin films of the metallic superconductor NbN. Despite the electrostatic screening due to the large intrinsic carrier density of this material, we observe measurable, ambipolar modulations of the superconducting critical temperature, whose amplitude depends on the gate voltage but also on the film thickness. The results unambiguously indicate that the superconducting properties of the whole film are affected by the charge induced in a much thinner surface layer (whose thickness is of the order of the screening length). The results can be interpreted in terms of proximity effect between the surface layer (hosting the induced charge) and the underlying part of the film. Very interestingly, the effective screening length lambda_eff turns out to depend on the induced charge density: it departs from the Thomas-Fermi value and increases - suggesting that there is an upper limit for the volume charge density - on increasing the gate voltage. At very high electric fields, lambda_eff eventually becomes much larger than that predicted by a standard screening theor

INTEGRATED AEROSPACE SYSTEMS DESIGN COURSE: AN EDUCATIONAL EXPERIENCE AT POLITECNICO DI TORINO
No full textInsight into particle production mechanisms via angular correlations of identified particles in pp collisions at sqrt(s)=7 TeV
No full textTwo-particle angular correlations were measured in pp collisions at root s = 7 TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon-baryon and anti-baryon-anti-baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This effect is interpreted in the context of baryon production mechanisms in the fragmentation process. It currently presents a challenge to Monte Carlo models and its origin remains an open question

Paesaggio e identità /Paisagem e identidade
No full textIl breve saggio ha per tema le trasformazioni del paesaggio e mette in luce l'importanza che in tal senso assumono le migrazioni internazionali, come quelle (analizzate nel volume che include questo capitolo) dovute alla migrazione italiana nel Sud del Brasile. Attraverso questi processi si compie una fase nuova nella territorializzazione di un'area: i nuovi venuti sono portatori di valori e competenze culturali che fanno parte del loro patrimonio culturale ed identitario e, facendo riferimento ad essi, contribuiscono a reinterpretare e a riplasmare il paesaggio, favorendo un fenomeno di ibridazione
Special Metrics and Group Actions in Geometry
No full textThis volume is a follow-up to the INdAM workshop "New perspectives in differen- tial geometry" that took place on 16-20 November 2015: https://newperspectivesindg.wordpress.com The editors are deeply grateful to the Istituto Nazionale di Alta Matematica "Francesco Severi" (INdAM) for generously sponsoring and hosting the event in Rome, and to the Institute's President, Giorgio Patrizio, for his steadfast support. We are indebted to Diego Conti and Caterina Stoppato for the invaluable hard work in organising the workshop, and to Graziano Gentili and Andrew Swann for playing a key role on the scientific committee. We would also like to thank wholeheartedly the conference speakers: Ilka Agricola, Adrián Andrada, Vestislav Apostolov, John Armstrong, Fiammetta Battaglia, Roger Bielawski, Fran Burstall, Vicente Cortés, Johann Davidov, Paul Gauduchon, Marisa Fernández, Nigel Hitchin, Claude LeBrun, Thomas Madsen, Stefano Marchiafava, Vicente Muñoz, Paolo Piccinni, Uwe Semmelmann and Luis Ugarte. On the occasion of the workshop we celebrated the 60th birthday of Simon Salamon, a worldwide leading scholar at the forefront of research in differential geometry whose extensive body of work centres around Riemannian and com- plex manifolds defined with reference to the action of a Lie group. The unique contributions appearing in this book focus on a variety of cutting-edge topics revolving around Salamon's interests: quaternionic and octonionic geometry, twistor spaces, almost-complex manifolds, harmonic maps, exceptional holonomy, Einstein metrics, spinors, homogeneous spaces and nilmanifolds, special geometries in dimensions 5, 6, 7 and 8, conformal geometry, moduli spaces, gauge theory, 4- manifolds, symplectic manifolds and integrable systems. Simon Salamon is Professor of Geometry at King's College, London, and previously worked at Politecnico di Torino, Imperial College and Oxford University. The workshop was widely attended by his colleagues, friends and former students from all over the world, and this volume represents both a fitting tribute to a trailblazing force in the field and a compelling testimony to the profound and longstanding impact that Salamon has on the mathematical community. Heartfelt thanks go to the authors who accepted the invitation to publish here: Fiammetta Battaglia, Giovanni Bazzoni, Indranil Biswas, Fran Burstall, Vicente Cortés, Andrew Dancer, Johann Davidov, Malte Dyckmanns, Marisa Fernández, Paul Gauduchon, Claude LeBrun, Andrea Loi, Jason Lotay, Thomas Madsen, Andrei Moroianu, Vicente Muñoz, Antonio Otal, Paolo Piccinni, Simon Salamon, Stefan Suhr, Andrew Swann, Aleksy Tralle, Luis Ugarte, Raquel Villacampa, Dan Zaffran and Fabio Zuddas. We strongly believe these papers will be extremely relevant to the advancement of academic research and are certain they will serve generations to come
