L'arte grafica nel diciottesimo secolo

Nuova galassia tipografico-digitale
2007
Nell’era digitale nella quale viviamo, che la grafica sia “fuori delle regole” è una constatazione ormai pacifica e condivisa. Con l’avvento del (personal) computer, negli anni ottanta, si determina infatti un momento cruciale nella storia della comunicazione visiva (il Mac è del 1984). Il computer imprime un drastico rinnovamento delle tecniche operative, accelerando il processo (già in corso) da un metodo di progetto essenzialmente razionale a modalità di comunicazione sempre più impattanti, e sempre meno ancorate alle regole.
Le architetture non realizzate di Guarino Guarini: la Chiesa di S. Filippo Neri a Casale
2007
Il trattato Architettura Civile di Guarino Guarini riporta alcuni progetti di edifici religiosi non realizzati. Tra questi, la chiesa di San Filippo Neri a Casale Monferrato. La ricostruzione del modello digitale consenti di esaminare la geometria dell'impianto e la complessità delle superfici voltate.
Formation of secondary carbonates and native sulphur in sulphate-rich Messinian strata, Sicily
2010
Abstract Microbially formed authigenic carbonates accompanied by native sulphur are present in the ‘Calcare Solfifero’ below a thick succession of gypsum deposited during the Messinian salinity crisis in Sicily. We sampled these carbonates and associated sulphur in five former sulphur mines to subject them to a detailed petrographic and geochemical study in order to explore their different modes of formation. Native sulphur formed in conjunction with microbial sulphate reduction, which is reflected in its depletion in 34S (δ34S values as low as − 2‰ vs. V-CDT) and an enrichment of 34S in the residual sulphate (δ34S values as high as + 61‰). The oxidation of organic matter by sulphate reduct…
Near surface seismostratigraphic modelling of the Bandita plain in Palermo town (Italy) from integra-ted analysis of HVSR and stratigraphic data
2016
The Horizontal to Vertical Spectral Ratio (HVSR) noise method (Nakamura, 1989) is nowadays widely used to estimate the resonance frequencies of geological structures (Bonnefoy-Claudet, 2006). However, often HVSR is also used to obtain information on the depth of the seismic bedrock and on thickness and seismic velocity of the process overburden deposits, using inversion techniques of the H/V curve (Fäh et al., 2003). This nevertheless produce results with large uncertainty intervals of parameters, and then must be necessarily constrained by detailed stratigraphic information. An application of HVSR inversion is presented in order to verify the effectiveness of this technique for purposes of…

Detection of Invisible Damages in ‘Rojo Brillante’ Persimmon Fruit at Different Stages Using Hyperspectral Imaging and Chemometrics
2021
[EN] The main cause of flesh browning in 'Rojo Brillante' persimmon fruit is mechanical damage caused during harvesting and packing. Innovation and research on nondestructive techniques to detect this phenomenon in the packing lines are necessary because this type of alteration is often only seen when the final consumer peels the fruit. In this work, we have studied the application of hyperspectral imaging in the range of 450-1040 nm to detect mechanical damage without any external symptoms. The fruit was damaged in a controlled manner. Later, images were acquired before and at 0, 1, 2 and 3 days after damage induction. First, the spectral data captured from the images were analysed through…

Geophysical contribution to the reconstruction of the hydrological model of "Barcellona-Milazzo plain" groundwater body, northen Sicily
2019
The “Barcellona-Milazzo plain” groundwater body in the northen Sicily, was analysed in detail, through numerous geophysical measurements that were integrated with stratigraphic data in order to reconstruct the hydrological model. The “Barcellona-Milazzo plain” (BMP) groundwater body has been identified within the coastal sector between the village of Oliveri, to the west, and Capo Rasocolmo, to the east. It also includes several rivers that rise further south in correspondence with the Peloritani ridge and flow into the wide Barcellona-Milazzo alluvial plain. On the basis of several geophysical and geological data analysis and interpretation have been used to reconstruct the composition and…
