Isotactic polypropylene solidification under pressure and high cooling rates. A master curve approach
2000
Solidification in industrial processes very often involves flow fields, high thermal gradients and high pressures: the development of a model able to describe the polymer behavior becomes complex. Recently a new equipment has been developed and improved to study the crystallization of polymers when quenched under pressure. An experimental apparatus based on a modified, special injection moulding machine has been employed. Polymer samples can be cooled at a known cooling rate up to 100 °C/s and under a constant pressure up to 40 MPa. Density, Micro Hardness (MH), Wide angle X-ray diffraction (WAXD), and annealing measurements were then used to characterize the obtained sample morphology. Res…

La trasfigurazione del principio di legalità penale statale nel prisma del diritto europeo
2012
Il contributo esamina l’ormai risalente questione del possibile contrasto del diritto penale di fonte europea con il principio di legalità penale statale, alla luce delle novità introdotte dal Trattato di Lisbona. In particolare, esso evidenzia come la definitiva attribuzione di una competenza penale (pur sempre indiretta) all’Unione da parte del nuovo assetto istituzionale introdotto a Lisbona non abbia irreparabilmente compromesso l’esito del suddetto contrasto, nei termini negativi o di un’inevitabile capitolazione delle garanzie della legalità penale, o viceversa, del necessario innalzamento della barriera dei controlimiti contro il rischio di tale capitolazione. In proposito, lo scritt…

Eiropas Savienības dalībvalsts Konstitucionālās tiesas tiesības atzīt Eiropas Savienības tiesas spriedumu par spēkā neesošu savā teritorijā
2021
Eiropas Savienības tiesisko stabilitāti 2020.gadā satricināja nebijis precedents –Apvienotās Karalistes izstāšanās no Savienības. Savienības turpmākās pastāvēšanas jautājumi kļuva arvien aktuālāki, spilgtāk iezīmējot jau esošās domstarpības starp dalībvalstu un Savienības interesēm. Fundaments, kas satur Savienību kopā, pamatā atspoguļojas Savienības tiesībās un to piemērošanā. Tomēr, pamanāma ir kļuvusi arī šī fundamenta šķelšana, dalībvalstīm pakāpeniski ievirzot tendenci Eiropas Savienības Tiesas kompetences apšaubīšanā. 2020.gada, vienu no spilgtākajiem tiesu precedentiem, raksturo Vācijas Konstitucionālās tiesas spriedums, ar kuru Eiropas Savienības Tiesas nolēmums atzīts par spēkā nee…

El poder financiero de los municipios y su marco constitucional
2017
La Constitución establece un marco para el ejercicio del poder financiero por parte de los distintos entes territoriales. Los Municipios, en aplicación de preceptos de la Carta Manga, dispondrán de autonomía y suficiencia financiera (art. 140 y 152 CE). Asimismo, y en aplicación del principio de competencia, los Entes Locales podrán desarrollar su potestad reglamentaria en las materias que le sean propias. Por todo ello, el presente trabajo tiene por objeto el análisis y valoración de la aplicación y eficacia que despliegan estos principios constitucionales en el ejercicio del poder financiero municipal y sus límites cuando confluyan con otras Administraciones The Constitution establishes a…
REWAQUA: an advanced technology for water purification in sustainable aquaculture based on photocatalytic ozonation
2017
The present study has been undertaken in order to test the real potential of photocatalytic ozonation in a bench-scale recirculating aquaculture system working on a 180 L reef coral aquarium. Notably, this choice may be considered representative. In fact, (i) the system is virtually closed so that fresh water turnover is practically negligible, (ii) the presence of living organisms is highly diversified (corals, fishes, molluscs, echinoderms and crustaceans) and some of them are particularly sensitive to water quality, (iii) high salinity strongly puts a strain on the purification system. The hereby presented purification method has been named REWAQUA, which stands for REcycling Water for A…
Prediction of flow fields in a dual-impeller stirred vessel
1999
Numerical simulations were connected for the flow field in a baffled tank stirred by a dual Rushton impeller. For this geometry, LDV measurements show a characteristic dependence of the flow patterns upon the position of the impellers. Two advanced modeling approaches were tested. In the first, the vessel was divided info two concentric blocks, coupled by, a sliding grin technique, and simulations were conducted in time-dependent mode. In the second approach, the vessel was modeled as two partially over-lapping I regions, the inner one rotating with the impeller and rite outer one stationary simulations were run in steady-state mode for each of the two regions, while information was iterati…
