La gratuità del divino e la contingenza del mondo fra weak theology e teodicea
2016
As the relationship between God's gratuitousness and the contingecy of the world is concerned, Leibnizian modern theodicy and weak theology seem to radically contradict each other. Nevertheless, both perspectives are able to preserve the simultaneous presence of gratuity and unconditioned givenness of theophany together with the contingency of reality in its heteronomy from the rules of the creationist order, since it is also determined by fortuity. In this way both positions are much more closer than waht they might seem at a first sight.
A comparison of Microtops II and satellite ozone measurements in the period 2001-2011
2013
Daily average total ozone Microtops measurements obtained during several campaigns conducted from 2001 to 2011 at latitudes from 31 to 68N and in different seasons are compared with satellite observations. The Microtops ozone is derived using different wavelength combinations (Channel I, 305.5/312.5. nm; Channel II, 312.5/320. nm; and Channel III, 305.5/312.5/320. nm). Satellite data from TOMS, OMI, GOME, and GOME-2 are used in the comparison. The three Microtops channels show a high correlation with the satellite retrievals. Channel I shows the best results and produces a mean bias deviation (MBD) less than 2.14% with respect to TOMS, OMI and GOME. The MBD increases to 3% in the comparison…
Análisis criptopaleontológico del lapidario de Teofrasto (s. III a.C.)
2013
The work “Perì líthon” or Teofrasto’s “Treatise of stones” has been considered the oldest text still available about minerals and rocks, even though it has remained incomplete. In this paper, the study of its contents shows that eleven of the stones called by geographic or cryptic names are either fossils from plants or vertebrates or chemical fossils. Therefore, the “Perì líthon” should also be considered as the oldest known treatise about palaeontology, because in addition to the fossils mentioned, it refers specifically to the fossilisation process.La obra “Perì líthon” o “Tratado de Piedras” de Teofrasto, es considerado el texto más antiguo conservado sobre minerales y rocas, aunque hay…
Introducing Thermal Inertia for Monitoring Snowmelt Processes With Remote Sensing
2019
Thermal inertia has been successfully used in remote sensing applications that span from geology, geomorphology to hydrology. In this paper, we propose the use of thermal inertia for describing snow dynamics. Two different formulations of thermal inertia were tested using experimental and simulated data related to snowpack dynamics. Experimental data were acquired between 2012 and 2017 from an automatic weather station located in the western Italian Alps at 2,160 m. Simulations were obtained using the one‐dimensional multilayer Crocus model. Results provided evidences that snowmelt phases can be recognized, and average snowpack density can be estimated reasonably well from thermal inertia o…

Tomografia Sonica ed Ultrasonica per il supporto all’intervento di restauro della statua del togato di Petrara (I Sec. D.C.)
2008
Nel 2003, a Locri (RC), è stata ritrovata la statua-ritratto in marmo del c.d. “togato di Petrara” (I sec. d.C.), rappresentata in Fig. 1, come si presenta dopo il restauro. Si tratta, probabilmente di una statua onoraria di un magistrato del municipium locrese, alta circa m 2,16 ma spezzata in tre parti: piedi con basetta, testa e figura. Dal marzo al luglio 2008 sono state eseguite le operazioni di restauro del manufatto per ricomporre la statua e porla nuovamente in posizione eretta. Una notevole lesione, infatti, era visibile sul fianco sinistro e sul retro. La causa di tale lesione si individuava subito con la presenza di un grosso perno a sezione quadrata inserito già in antico per il…
La versione greca della cost. Imperatoriam e la sua attribuzione
2016
The Greek version of the const. Imperatoriam reproduces a discourse made by an antecessor of Justinian’s age in the introductory lesson of his course on Institutes. He translated the constitution with the addition of didactical explications and clarifying remarks. Some terminological peculiarities induce to deny that this antecessor was Theophilos. Rather, we are faced with a fragment of teaching’s activity on Institutes of a not-recognizable Justinianic antecessor.
The Best Hedging Strategy in the Presence of Transaction Costs
2009
Considerable theoretical work has been devoted to the problem of option pricing and hedging with transaction costs. A variety of methods have been suggested and are currently being used for dynamic hedging of options in the presence of transaction costs. However, very little was done on the subject of an empirical comparison of different methods for option hedging with transaction costs. In a few existing studies the different methods are compared by studying their empirical performances in hedging only a plain-vanilla short call option. The reader is tempted to assume that the ranking of the different methods for hedging any kind of option remains the same as that for a vanilla call. The …
Indagini geobotaniche sulla componente terofitica della flora sarda.
2005
L’abbondanza di terofite contribuisce largamente alla caratterizzazione paesaggistica e naturalistica della Sardegna. Inoltre, molte delle specie annuali che compongono la flora dell’isola possiedono un valore storico-culturale, poiché riflettono diversi tipi di utilizzo delle risorse territoriali da parte dell’uomo. Le attività agricolo-pastorali, lo sviluppo tecnologico e l’urbanizzazione hanno incrementato il numero e la frequenza delle specie terofitiche presenti sull’isola. Attualmente, esse rappresentano circa il 40 % della flora sarda (Camarda, 1984a; Bocchieri, 1995) e possiedono un ruolo ecologico di prim’ordine, sia nella produzione di biomassa, sia nella protezione del suolo dall…
Optimization of Low-Cost Monitoring Systems for On-Site Earthquake Early-Warning of Critical Infrastructures
2020
In the last years, monitoring systems based on low-cost and miniaturized sensors (MEMS) revealed as a very successful compromise between the availability of data and their quality. Also applications in the field of seismic and structural monitoring have been constantly increasing in term of number and variety of functions. Among these applications, the implementation of systems for earthquake early warning is a cutting-edge topic, mainly for its relevance for the society as millions of peoples in various regions of the world are exposed to high seismic hazard. This paper introduces the optimization of an already established seismic (and structural) monitoring system, that would make it suit…
