Dispersion relations applied to double-folding potentials from chiral effective field theory

2020

We present a determination of optical potentials using the double-folding method based on chiral effective field theory nucleon-nucleon interactions at next-to-next-to-leading order combined with dispersion relations to constrain the imaginary part. This approach is benchmarked on O16-O16 collisions, and extended to the C12-C12 and C12-O16 cases. Predictions derived from these potentials are compared to data for elastic scattering at energies up to 1000 MeV, as well as for fusion at low energy. Without adjusting parameters, excellent agreement with experiment is found. In addition, we study the sensitivity of the corresponding cross sections to the nucleon-nucleon interactions and nuclear d…

Probing chiral interactions up to next-to-next-to-next-to-leading order in medium-mass nuclei

2019

We study ground-state energies and charge radii of closed-shell medium-mass nuclei based on novel chiral nucleon-nucleon (NN) and three-nucleon (3N) interactions, with a focus on exploring the connections between finite nuclei and nuclear matter. To this end, we perform in-medium similarity renormalization group (IM-SRG) calculations based on chiral interactions at next-to-leading order (NLO), N$^2$LO, and N$^3$LO, where the 3N interactions at N$^2$LO and N$^3$LO are fit to the empirical saturation point of nuclear matter and to the triton binding energy. Our results for energies and radii at N$^2$LO and N$^3$LO overlap within uncertainties, and the cutoff variation of the interactions is w…

Ab initio limits of atomic nuclei

2019

We predict the limits of existence of atomic nuclei, the proton and neutron drip lines, from the light through medium-mass regions. Starting from a chiral two- and three-nucleon interaction with good saturation properties, we use the valence-space in-medium similarity renormalization group to calculate ground-state and separation energies from helium to iron, nearly 700 isotopes in total. We use the available experimental data to quantify the theoretical uncertainties for our ab initio calculations towards the drip lines. Where the drip lines are known experimentally, our predictions are consistent within the estimated uncertainty. For the neutron-rich sodium to chromium isotopes, we provid…

Gares exurbanisées et développement urbain : Le cas des gares TGV bourguignonnes

2009

Dès la mise en service de la ligne TGV Sud-Est, au début des années 80, la Bourgogne a bénéficié de la création de deux nouvelles gares TGV, aménagées en périphérie des pôles urbains du Creusot et de Mâcon. Malgré leurs fonctions réduites, ces nouvelles gares périurbaines ont suscité d’ambitieux projets d’aménagement. De nouvelles zones d’activités ont ainsi vu le jour à proximité de ces gares. Ces projets n’ont eu toutefois que des retombées limitées en matière d’implantation d’activités économiques. Since the opening of TGV south-east railway line at the beginning of the 80s Bourgogne has profited by construction of two new stations beyond the edge of Le Creusot and Mâcon. Despite their l…

La protratta inerzia nell'esigere il credito tra remissione tacita, Verwirkung e divieto di abuso del diritto.

2022

Il saggio muove da un recente sentenza della Corte di cassazione in tema di protratta inerzia nell'esercitare un diritto di credito non ancora prescritto. La Suprema corte ha ritenuto che tale inerzia protratta nel tempo, se suffragata da elementi circostanziali oggettivamente idonei a ingenerare nel debitore un affidamento nella remissione del diritto di credito da parte del creditore per facta concludentia, determina che la improvvisa richiesta di integrale pagamento costituisca abuso del diritto. Sul modello della Verwirkung, elaborata nell’esperienza tedesca, il diritto così esercitato deve ritenersi tacitamente rinunciato. Il saggio critica tanto la soluzione quanto l'impianto dogmatic…

Buona fede, ragionevolezza e «efficacia immediata» dei principi

2017

Il volume affronta il tema del ruolo assolto dalla buona fede in seno allʼinterpretazione del contratto, la questione, particolarmente controversa, delle caratteristiche e della funzione della ragionevolezza in materia contrattuale e, infine, il connesso e prevalente problema dellʼefficacia diretta dei principî, specie nellʼambito dei rapporti contrattuali. La prospettiva consente di allargare lo sguardo alla fisionomia attuale dellʼordinamento giuridico italiano, anche alla luce del processo di integrazione europea e dellʼinfluenza di ordinamenti internazionali. Sullo sfondo si stagliano le questioni del rapporto tra legislazione e giurisdizione, dellʼindividuazione delle fonti del diritto…

The state-of-the-art of collaborative technologies for initial vocational education : a systematic literature review

2018


 
 
 Future workplaces require collaboration skills in which members of different work communities use technologies to solve complex problems. Vocational education and training (VET) programs need to meet the challenge to prepare students to be part of a competent workforce. Particularly initial vocational education is under pressure to develop learners’ collaboration skills and abilities. To date, however, no attempt has been made to perform a comprehensive review of the use of computer-supported collaborative learning (CSCL) technologies across different vocational education settings to account for contextual factors of VET. In this systematic review, 26 published studies …

La posizione del terzo nel diritto delle obbligazioni. Uno studio evolutivo-comparato dal diritto romano ai più recenti strumenti di tutela, con part…

Lʼindividuazione di un filo conduttore che possa aiutare ad individuare lo sviluppo e i processi storici che hanno interessato la tutela e la protezione del terzo, a partire dal modo in cui il problema ha trovato configurazione in diritto romano, ammesso che si possa riconoscere che ne abbia escogitata una, sino allʼattuale profilarsi delle questioni teorico-dogmatiche sul punto, se da un lato appare senza dubbio come un problema stimolante e ricco di spunti, dallʼaltro si presta senza dubbio a concretizzare quei problemi e quei dubbi a cui si è appena fatto riferimento. Consapevoli di questo genere di dilemmi, nellʼaffrontare lʼargomento in oggetto si è quindi cercato di adottare un metodo…
