The geological map of Sardinia (Italy) at 1:250,000 scale
No full textOver the last 25 years the Italian national geological mapping program of the Italian Geological Survey (CARG Project, italian: Progetto Carta Geologica) at 1:50,000 scale has led to significant improvements in the geological knowledge for the Island of Sardinia (Italy). As a result, about one half of the island now is covered by new geological maps with 1:10,000–1:25,000 accuracy and geological maps at the 1:50,000 scale whose explanatory notes are available electronically. At the beginning of the CARG Project a geological map for Sardinia Island at 1:200,000 scale was published [Carmignani, L. (1996). Carta Geologica della Sardegna (1:200.000). Servizio Geologico Nazionale, Regione Autonoma della Sardegna], summarizing all the geological information available at that time, and a book with explanatory notes for the map was later published [Carmignani, L., Oggiano, G., Barca, S., Conti, P., Salvadori, I., Eltrudis, ... Pasci, S. (2001). Geologia della Sardegna: Note Illustrative della Carta Geologica della Sardegna in scala 1:200.000, Memorie Descrittive della Carta Geologica d'Italia (Vol. 60). Roma: Servizio Geologico d'Italia, 283 pp]. The enclosed Geological map of Sardinia at 1:250,000 scale incorporates all maps of the CARG Project, unpublished author studies and recently published maps and represents the most updated synthesis of an area characterised by a complex geological evolution that, with few exceptions, can be considered continuous during the last 540 Ma. The main events that influenced the geology of the island are the Variscan orogen that deeply involved the passive margin of North Gondwana and then the complex episodes that occurred in the present-day Mediterranean area after the accretion of Pangea up to the opening of the Tyrrhenian basin
Paralipomeni nella storia del teatro italiano del Settecento: la "querelle" sugli spettacoli nella Firenze dei Lorena e la "Polissena" di Giovanni Carmignani
No full textAttraverso lo studio di documenti manoscritti e a stampa di prima mano, il saggio ricostruisce la genesi, la storia e la fortuna della "Polissena. Tragedia" di Giovanni Carmignani (primo critico ufficiale dell'Alfieri), nel quadro delle polemiche illuministiche in materia di teatri e di spettacoli
An assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,
Scienza, cultura, società nel mondo del vino
No full textIl processo di fidelizzazione del vino italiano al territorio di origine è stato favorito dall’evoluzione normativa italiana e comunitaria a tutela ed a garanzia della qualità legata all’origine geografica.
Il vino, la vite e il territorio vitivinicolo diventano patrimonio culturale nazionale da tutelare e valorizzare negli aspetti di sostenibilità sociale, economica, produttiva ambientale e culturale ai sensi del codice dei beni culturali italiano; taluni paesaggi vitati vengono ricompresi nell’elenco dei siti dell’Unesco italiani in quanto paesaggio culturale.
Tuttavia la salvaguardia della tradizione, implicita nella tutela dei valori identitari elaborati dal territorio vitato, non può frenare l’evoluzione continua del rapporto tra scienza a cultura e società; tradizione e innovazione tecnologica sono sempre state in rapporto dinamico nel mondo del vino ed hanno consentito l’accoglimento di nuove tecniche e tecnologie anche nella produzione dei vini di qualità legati all’origine geografica, previa modifica del loro disciplinare.
La transizione ecologica, inclusiva e socialmente equa che l’Europa è pronta a realizzare nella riorganizzazione dei settori produttivi rende opportuno, anche a fini concorrenziali, che il territorio vitivinicolo ed il suo patrimonio immateriale possa usufruire di originali standard di elevata sostenibilità sociale, economica e ambientale da affiancare ai disciplinari delle produzioni DOP e IGP.The loyalty process of Italian wine to the territory of origin has been favored by the evolution of Italian and Community legislation to protect and guarantee the quality linked to the geographical origin.
The wine, the vine and the wine-growing area become national cultural heritage to be protected and enhanced in the aspects of social, economic, production, environmental and cultural sustainability in accordance with the Italian code of cultural heritage; the revival of vineyard landscapes are included in the list of Italian Unesco sites as a cultural landscape.
However, the safeguarding of tradition, implicit in the protection of the identifying values elaborated by the vineyard area, cannot stop the continuous evolution of the relationship between science, culture and society.
The ecological, inclusive and socially equitable transition that Europe is ready to carry out in the reorganization of the productive sectors makes it appropriate, also for competitive purposes, that the wine-growing area and its intangible heritage can take advantage of original standards of high social, economic and environmental to be placed side by side with the disciplinary of the PDO and PGI productions

Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity
Flame spread over acrylic cylinders in microgravity: effect of surface radiation on flame spread and extinction
No full textLuca Carmignani, San Diego State University & University of California San DiegoShun Sato, Toyohashi University of TechnologySubrata Bhattacharjee, San Diego State UniversityICES509: Fire Safety in Spacecraft and Enclosed HabitatsThe 48th International Conference on Environmental Systems was held in Albuquerque, New Mexico, USA on 08 July 2018 through 12 July 2018.During the 1990s several combustion experiments involving cellulose and PMMA as burning fuels were conducted on the Space Shuttle varying the oxygen concentration up to 50% in two pressure levels of 1 and 2 atm (Solid Surface Combustion Experiments, SSCE). These pioneering experiments were among the first attempts to explore flame spread in a quiescent microgravity environment. Although a number of papers have been published on the flame spread rate over thin and thick fuels, digitizing the videos, previously stored in VHS media, and application of recently developed image analysis tools have allowed us to re-analyze those videos for further understanding of these unique experimental results. Specifically, this work explores the effect of surface radiation on flame spread and extinction, starting from a qualitative analysis of the experiments. The comparison with samples from the more recent BASS (Burning And Suppression of Solid fuels) investigation suggest that radiative effects for flat and cylindrical fuels can be quite different, and are affected by the oxygen concentration. A non-dimensional surface radiation number is proposed that captures the geometric effect on radiation
