Density-functional theory of freezing of quantum liquids at zero temperature using exact liquid-state linear response
C. N. Likos,Saverio Moroni,Gaetano Senatore
Physics , 1996, DOI: 10.1103/PhysRevB.55.8867
Abstract: We apply density functional theory to study the freezing of superfluid {$^{4}\rm{He}$}, charged bosons and charged fermions at zero temperature. We employ accurate Quantum Monte Carlo data for the linear response function in the uniform phase of these systems, a quantity that has different behavior for large values of the wavevector than previously assumed. We find that, as a result of this {\it{exact}} behavior, different approximations in the density functional theory of freezing that involve linear response, all fail to correctly describe the crystallization in {\it{three dimensions}}, while yielding satisfactory predictions in {\it{two dimensions}}. This demonstrates the shortcomings of the currently popular density functional approximate theories to describe $3d$-freezing in the quantum regime. We also investigate the consequences of the exact asymptotic behavior of response functions on the form of effective interactions and polarization potentials in the electron gas, at small distances.
Magnetic Field Effect on the Pseudogap Temperature within Precursor Superconductivity
P. Pieri,G. C. Strinati,D. Moroni
Physics , 2002, DOI: 10.1103/PhysRevLett.89.127003
Abstract: We determine the magnetic field dependence of the pseudogap closing temperature T* within a precursor superconductivity scenario. Detailed calculations with an anisotropic attractive Hubbard model account for a recently determined experimental relation in BSCCO between the pseudogap closing field and the pseudogap temperature at zero field, as well as for the weak initial dependence of T* at low fields. Our results indicate that the available experimental data are fully compatible with a superconducting origin of the pseudogap in cuprate superconductors.

Abstract: The current Constitutional Law allows the Italian Regions to deliberate autonomously on health matters. Therefore, most of them, complying with the scientific evidences, the European Regulation n. 852/2004 and the National Law d.lgs 155/97, have abolished the sanitary certificate for the staff in food business and have introduced the professional training course in order to improve the food safety.

Abstract: In order to know the potential opportunities to bacteria’s contamination and survival in roast beef production process in a self service restaurant, were collected data, by direct observation of food handling practices and the environment hygiene. Furthermore a bacteriological survey on both raw and cooked roast beef, meat juice and kitchen environment was made. Finally, using an instant-read thermometer we investigated over the relationship between time, temperature and the number of bacteria in roast beef during the heat holding and the slicing process. Thus we demonstrated the importance of Good Manufacturing Practice (sanitation, maintenance of right temperatures, and exclusion of cross-contamination) during storage, handling and cooking. So to achieve a ready-to-eat roast beef safe for the consumers.
La incorporación de los territorios nacionales en el proceso de consolidación del estado argentino: El caso del territorio de la pampa central
Andes , 2005,
Abstract: in most of the manuscripts by the learned argentinean elite of the xixth century, the idea of civilization was identified as a manifestation of the national identity, an assumption that lead this elite to legitimate its own civilizing function and impulse a process of state consolidation. this process required the complete occupation of the territory dominated by the indigenous, which were considered -along with the caudillos- responsible for the failure of the national unification. the new territories were defined by the states power structures as virgin areas with infinite possibilities and economic advantages to be exploited. this political argument attracted national and foreign settlers that occupied these lands and began the productive organization of the future provinces. in this work i review the process of incorporation and subsequent organization of frontier lands after the conquista del desierto. particularly, i analyse the political and administrative structure of the territorio nacional de la pampa central, officially constituted in 1884 with the establishment of the first military authorities appointed to found and run new towns.
La incorporación de los territorios nacionales en el proceso de consolidación del estado argentino. El caso del territorio de la Pampa Central
Marisa Moroni
Andes , 2005,
Abstract: En la mayoría de los escritos de la élite letrada argentina del XIX, se identificó a la civilización como una manifestación de la identidad nacional, supuesto que las llevó a legitimar su función civilizadora y a impulsar el proceso de consolidación del Estado que requería la ocupación total del territorio, aún en manos de los indígenas a los que se responsabilizaba, junto con los caudillos, del fracaso de la unificación nacional. Desde las estructuras del poder estatal, se definió a los nuevos territorios como espacios vírgenes con infinitas posibilidades y ventajas económicas para explotar. Este argumento político atrajo pobladores -nacionales y extranjeros- que ocuparon y encaminaron la organización productiva de las futuras provincias. En este trabajo se realiza una aproximación al proceso de incorporación y posterior organización institucional de las tierras fronterizas incorporadas con la "Conquista al Desierto". En particular, se analiza la estructura político-administrativa del Territorio Nacional de la Pampa Central, constituido como tal en 1884, con el establecimiento de las primeras autoridades militares destinadas a fundar poblaciones y administrarlas políticamente.
Vincere e convincere. Processi e politica a Firenze dal 1922 al 1924
Sheyla Moroni
Annali di Storia di Firenze , 2013,
Abstract: I processi per reati politici (o ritenuti tali) svoltisi fra il 1922 e il 1924 rappresentano un prisma rivelatore delle reazioni dell’universo giudiziario al nascere del regime fascista. A maggior ragione, ciò succede a Firenze e provincia, dove i reati dei bienni rosso e nero sono commessi in un clima da temuta guerra civile. I processi, la loro copertura mediatica e i loro approdi giudiziari raccontano una provincia (e un paese) già consegnati, per stanchezza e disincanto, nelle mani dei fascisti all’indomani della marcia su Roma. Il nascente regime si mostra da subito all’altezza delle aspettative della maggioranza dell’opinione pubblica varando due amnistie che escludono dai loro benefici soltanto chi ha commesso e commette reati di opinione penalmente meno rilevanti ma politicamente molto più insidiosi.

La ricerca-azione in biblioteca: il metodo, le esperienze e un caso significativo Action Research in the Library: Method, Experiences, and a Significant Case
Ilaria Moroni
JLIS.it , 2011, DOI: 10.4403/jlis.it-4702
Abstract: This article aims to promoting action research in library contexts by illustrating the method and its applications in library, and by presenting a meaningful case. Action research, devised in 1950s, was spread in information sciences since 1990s, with results that have been interesting in promoting change of involved people and organizations. The method is based on engaging a group coordinated by a researcher. Problem analysis is functional to realizing improvement interventions, in a recursive process of reflection, action, evaluation, and result sharing. The action research case at the University Milano Bicocca Library is meaningful under various aspects: increase of motivation and awareness in the working group that was responsible of improving the perception of library services; complementary use of quantitative and qualitative research methods in order to analyze users' service utilization and satisfaction; realization of many interventions, coherent with research results, aimed to enhance service usage and perceived quality; self-reflection and reflection on the organizational context, benchmarking with other libraries and assessment of the realized activities in the perspective of continuing improvement; internal sharing and external diffusion of the project to the advantage of librarians, users, and researchers. L’articolo si propone di diffondere l’utilizzo della ricerca-azione nel contesto bibliotecario, illustrando il metodo e le sue applicazioni nelle biblioteche e presentando un caso significativo. La ricerca-azione, ideata negli anni Cinquanta, si è diffusa nell’ambito delle scienze dell’informazione a partire dagli anni Novanta con risultati interessanti per i cambiamenti promossi nelle persone e nelle organizzazioni coinvolte. Il metodo prevede il coinvolgimento di un gruppo di persone coordinate da un ricercatore e l’analisi del problema è funzionale alla realizzazione di interventi migliorativi, in un processo ricorsivo di riflessione, azione, valutazione e condivisione dei risultati. L’applicazione della ricerca-azione nella Biblioteca di Ateneo di Milano-Bicocca appare significativa per diversi aspetti: la crescita della motivazione e della consapevolezza del gruppo di lavoro che aveva il compito di migliorare la percezione dei servizi bibliotecari; l’utilizzo complementare di metodi quantitativi e qualitativi della ricerca per analizzare l’uso dei servizi e la soddisfazione degli utenti; la realizzazione di molti interventi coerenti con gli esiti delle indagini e mirati a incrementare l’uso dei servizi e la qualità percepita; il lav
Le potenzialità dell'Import UNIMARC nell'esperienza del Polo MIL
Chiara Moroni
Bollettino del CILEA , 2009, DOI: 10.1472/bc.v0i112.1438
Abstract: L’applicativo SBN Unix C/S dispone della funzionalità Import UNIMARC che permette di acquisire sulle basi dati di polo e biblio informazioni derivanti da un data base gestito senza colloquio con SBN. Nel corso del 2008 il CILEA ha maturato una notevole esperienza sull’uso di questa procedura, eseguendo una serie di importazioni per biblioteche afferenti al polo MIL. Le possibilità offerte dalla procedura e l’esito positivo dell’importazioni effettuate rendono l’Import UNIMARC un’attività utile sia per le Biblioteche già afferenti a SBN, che per quelle che desiderino aderirvi. The application SBN Unix C/S handles the feature Import UNIMARC, allowing to obtain information on the data of pole and library from a database, without conversation with SBN. In 2008, CILEA gained a remarkable expe-rience on the usage of this procedure, importing data for some libraries belonging to the MIL pole. The chances offered by the procedure and the successful imports render Import UNIMARC a useful activity both for libraries belonging to SBN and for libraries wanting to join it.
