La ceramica dal casale in località Céscole a Itri (LT): nuove fonti archeologiche per lo studio della società bassomedievale tra la contea di Fondi ed il porto di Gaeta
No full textL'area del golfo di Gaeta sino ad ora non è stata interessata da sistematiche ricerche di archeologia medievale. In particolare, ben poco si conosce della cultura materiale bassomedievale, soprattutto della ceramica di uso quotidiano. In questo contributo si vuole fornire una descrizione dei materiali rinvenuti all’interno e nell’area circostante il casale in località Céscole in Itri (Lazio, Italia), consistenti principalmente in anfore di varia dimensione di riutilizzo e in altre forme di ceramica acroma e dipinta. Nella prima parte sono raccolte informazioni sul contesto storico regionale del XIV secolo ed alcune brevi note sulla topografia dell’area del casale. La seconda parte fornisce uno studio dettagliato dei materiali condotto col fine di interpretare al meglio quelle che sembrerebbero essere attestazioni di particolare interesse per le produzioni tardo medievali dell’area costiera campano-laziale, nonché i primi di questo tipo documentati nell’area di Itri. Il casale con torre in località Céscole costituisce con i suoi materiali un nuovo contesto che, a seguito di ulteriori e più approfondite indagini, potrà in futuro fornire dati di natura archeologica utili alla ricostruzione del paesaggio rurale orbitante intorno al Castrum Ytri tra XIV e XV secolo.To date, the area of the gulf of Gaeta has never been involved in systematic Medieval Archaeology research. Very little is known, for instance, about the late Medieval material culture of this region, especially concerning pottery for everyday use. The aim of this paper is to provide a first description of the pottery found in and around the casale located at le Céscole in Itri (Lazio, Italy). This material consists mostly of amphorae and other painted wares. In the first part of the paper, we provide information about the regional historical context for the XIV century. The second part includes a detailed study of the pottery found in the casale and aims to give a first interpretation of it. The pottery could be an important attestation of the late Medieval production of the coast between Lazio and Campania and the first of this kind ever to be reported from Itri. The casale at le Céscole, together with its pottery, represents a new context from which, through further investigations, we can hope to extrapolate more archaeological data in the near future. These data will surely aid us in reconstructing the rural landscape orbiting around the Castrum Ytri between the XIV and the XV century
Topology and quantum states: The electron-monopole system
No full textThis paper starts by describing the dynamics of the electronmonopole system at both classical and quantum level by a suitable reduction procedure. This suggests, in order to realise the space of states for quantum systems which are classically described on topologically non-trivial configuration spaces, to consider Hilbert spaces of exterior differential forms. Among the advantages of this
formulation, we present—in the case of the group SU(2), how it is possible to obtain all unitary irreducible representations on such a Hilbert space, and how it is possible to write scalar Dirac-type operators, following an idea by K¨ahler

No full textThis thesis was designed and built to test a new system of hardware-software combined study for the control and management of geological risk arising from mud flow landslides and slopes slow movements.
The various issues that arise at present in the landslide management risk are related to poor knowledge of the territory from the geological, geomorphological and specially geodynamic point of view. In risk management modern technical software and hardware very often are neglected, probably because no direct knowledge, that would allow a more advanced risk management in real time.
The latest hardware and software generation can identify, if associated with the availability of appropriate and correct data, any type of risk triggering cause arising from natural or anthropogenic factors.
This thesis focuses on the resolution of the above mentioned issues and finding detailed use not only at the civil protection level but also in the freelance profession.
In this thesis has been tested, with positive results, the Open - Source (OS) software applied to geological, geomorphological and geodynamic data collected on field in two areas; Olvera in Spain (detection area) and Oliveto Lucano in Italy (test area). OS software are indeed available and freely accessible at no cost.
The development of the project was divided into three main phases coinciding with the duration of doctorate (three years). They are: Geological and geomorphological survey (1st phase), server management versus UMPC and Open Source software (2nd phase) and two and three dimensional simulations of mud flow landslides with verify on test area (3rd phase).
More specifically, in the first year, in addition to the bibliographic collection and the choice of detection area (Olvera, Cadiz, Andalucia, Spain) and the test area (Oliveto Lucano, Matera, Basilicata, Italy) was carried out an intensive geological and geomorphological survey with the collection of all available data through the use of an Ultra Mobile Personal Computer (UMPC) above all in the Olvera. During the field work were selected and tested some of the OS software for digitization and data acquisition. Meanwhile in the laboratory was achieved on the network server, the web site, the DBMS database and the GUI of the WebGIS.
In the second year were improved techniques for survey detection through the use of UMPC and its direct connection with the server via HSDPA (High Speed Downlink Packet Access). Have also completed the selection, installation and development of other OS software needed to complete the project for the DBMS and the WebGIS area. Most important was the realization, through GIS and graphics tools chosen, geological and geomorphological maps and especially the map of susceptibility. After the realization of map of susceptibility, was performed a new detection phase on the field for a map validation.
In the third year the software development for the monitoring of movements by comparison of automatic objects placement on the territory from orthophotos or aerial photos of different years was performed and also the simulated two-and three-dimensional mud flow phenomena and slopes slow movements. All the simulations and tests carried out on landslides in the Olvera was verified on field. Even the simulation of landslides in the area of Oliveto Lucano have been tested on field.
During the three years of the PhD were produced poster, pbstract and articles. Here are the headlines: A tiicks published:

No full textLakes, both natural and artificial (reservoirs) are vital and strategic resources for life on our planet. At the same time, they are also highly vulnerable to human activities, especially if they are not properly preserved and used in a sustainable manner. These natural resources and their ecosystems have defined borders, while at the same time also strongly influenced by where they are located. Although there is a geographic limit between a lake ecosystem and neighbouring ecosystems, lakes are heavily influenced by the substances entering them in their incoming waters. Moreover, lakes are very complex systems influenced by many different factors, major ones being the materials dissolved in their waters, the climate of the region, energy exchanges with the atmosphere, the soil and the variety of organisms inhabit them, all of which are influenced by, and also influence, the lake system itself. This complexity means that when a lake is studied on the basis of a single discipline, it can often lead to misleading conclusions, or even incorrect results
