Coupling CFD with a one-dimensional model to predict the performance of reverse electrodialysis stacks
2017
Abstract Different computer-based simulation models, able to predict the performance of Reverse ElectroDialysis (RED) systems, are currently used to investigate the potentials of alternative designs, to orient experimental activities and to design/optimize prototypes. The simulation approach described here combines a one-dimensional modelling of a RED stack with a fully three-dimensional finite volume modelling of the electrolyte channels, either planar or equipped with different spacers or profiled membranes. An advanced three-dimensional code was used to provide correlations for the friction coefficient (based on 3-D solutions of the continuity and Navier-Stokes equations) and the Sherwoo…
Infondate le questioni di legittimità del nuovo comma 1 bis dell’art. 438 c.p.p.: la Corte sigla la conformità costituzionale della preclusione del r…
2021
La Corte costituzionale affronta il delicato tema dei rapporti tra giudizio abbreviato ed ergastolo, di recente riformato dalla legge n. 33 del 2019. Assecondando le istanze securitarie provenienti dalla collettività, il legislatore del 2019, con il nuovo comma 1 bis dell'art. 438 c.p.p., ha stabilito che è inibita la possibilità di accedere al rito premiale per gli imputati di reati puniti con la pena perpetua. Sollevate diverse questioni di legittimità costituzionale, la Corte le ha respinte, siglando la conformità a Costituzione della nuova disciplina. L'Autrice ripercorre il ragionamento dei giudici costituzionali, rilevando come, sulle questioni attinenti al merito della novum legislat…
Photochemical and photocatalytic isomerization of trans -caffeic acid and cyclization of cis -caffeic acid to esculetin
2016
Abstract The photoisomerization of trans-caffeic acid to cis-caffeic acid has been studied in the presence of N2 in homogeneous aqueous solutions and in suspensions of various TiO2 catalysts. The results supported the hypothesis of an energy transfer process from TiO2 to the substrate due to the recombination of the photogenerated electron–hole pairs. The differences among the measured photostationary [cis]/[trans] ratios have been attributed to the different physico-chemical properties of the catalysts. In particular, the lowest ratio measured in the presence of Merck TiO2 was ascribed to the very low adsorption of trans-caffeic acid onto the surface of this sample. In the presence of O2 a…
Il matrimonio, fondamento della famiglia. Nuove relazioni di coppia, nuove forme familiari
2016
L'articolo tesse un elogio dell’amore dell’uomo e della donna e della vita di famiglia. S’alimenta dell’intuizione che quest’amore possa diventare generativo in modo eminente: fa amare d’essere, può rivelare che essere è per amare, tal che se ne possa dire come di un trascendentale. Un assunto entusiastico, cui l’autore perviene scegliendo il linguaggio asciutto di un’analisi fenomenologica delle intenzionalità che li costituiscono, ai loro diversi livelli di realtà e di senso. In avvio si prende atto che nelle società della tarda-modernità esistono forme differenziate di coppia, ognuna sembra dar luogo ad una coppia mista; che non c’è la famiglia, ma una vera e propria polinesia di famigli…

Orientation and Crystallinity Measurements in Film Casting Products
2003
Film casting experiments were carried out with iPP under processing conditions causing the crystallization process to occur under orienting flow. Draw ratio and cooling rates were changed by varying mass flow rates and die thickness. The effect of processing conditions on film crystallinity was investigated by combining WAXS and FT-IR transmission methods, while orientation of both phases was measured by IR dichroism (according to Fraser's method) and successfully compared to birefringence measurements on final films. Crystallinity appears to be almost insensitive to draw ratio and cooling rate. Moreover the crystallinity profile turned out to be also constant along the transverse film dire…
Improvement of membrane performances to enhance the yield of vanillin in a pervaporation reactor.
2014
In membrane reactors, the interaction of reaction and membrane separation can be exploited to achieve a “process intensification”, a key objective of sustainable development. In the present work, the properties that the membrane must have to obtain this result in a pervaporation reactor are analyzed and discussed. Then, the methods to enhance these properties are investigated for the photocatalytic synthesis of vanillin, which represents a case where the recovery from the reactor of vanillin by means of pervaporation while it is produced allows a substantial improvement of the yield, since its further oxidation is thus prevented. To this end, the phenomena that control the permeation of bot…

Investigation of the Cooling of Hot Walls by Liquid Water Sprays
1999
An experimental study was conducted for the heat transfer from hot walls to liquid water sprays. Four full cone, swirl spray nozzles were used at different upstream pressures, giving mass fluxes impinging on the wall, G, from 8 to 80 kg m(-2) s(-1), mean droplet velocities, U, from 13 to 28 m s(-1) and mean droplet diameters, D, from 0.4 to 2.2 mm. A target consisting of two slabs of beryllium-copper alloy, each 4 x 5 cm in size and 1.1 mm thick, was electrically heated to about 300 degrees C and then rapidly and symmetrically cooled by water sprays issuing from two identical nozzles. The midplane temperature was measured by a fast response, thin-foil thermocouple and the experimental data …
