Seasonal cardenolide production and Dop5βr gene expression in natural populations of Digitalis obscura
2004
Productivity variations and seasonal fluctuations of cardenolides have been studied in 10 natural populations of Digitalis obscura distributed in three bioclimatic belts. Main cardenolides in D. obscura plants are those of the series A and such predominance (ca. 80-85%) over the series B metabolites is independent of the population studied or the degree of maturity of the leaves. Primary glycosides represent ca. 50-60% of total cardenolides; this percentage did not vary among populations or with the leaf age but increased in summer and decreased in winter. A correlation analysis between plant biomass and cardenolide content showed a positive relationship of these parameters, which, accordin…

NUOVO RUOLO FORMATIVO DELLE RELIGIONI STORICHE NELLE SOCIETA' POSTSECOLARI
2011
Le religioni sembrano assumere, a livello mondiale nuove forme di protagonismo; diventano, fra l'altro, immense riserve di senso che consentono ai singoli e alle comunità percorsi di vita autentica. Possono, se vissute e intese in una prosptettiva educativa, diventare scuole storiche di apprendimento etico diffuso e costituire quella forma di sostegno prepolitico alla politica del quale le democrazie ha necessità. La condizione prima è un atteggiamento nuovo, critico e aperto - non fondamentalista - sia in chi si definisce "religiosamente stonato" sia in chi dice di vivere una vita di fede.
Knowledge engineering and semantic formalism of symbolic relations. From medieval network to web 3.0
2020
A search has always been at the center of human concerns, the one of conditions and means to represent, to control well, and to communicate effectively with his environment. While technological advances and electronic gadgets such as smartphones, the Web, and online social networks currently allow addressing this concern, it has not always been the case. Our works in this thesis treat medieval documents considered as a medium of communication and as a model of the social network in the Middle Ages. These documents are called medieval illuminations. They were luxurious paintings used in that time to represent the environment and ideal world for elites such as prince, duke, etc. Those paintin…
The Effects of Digitalisation on Accounting Service Companies
2019
Rapidly expanding digitalisation profoundly affects several jobs and businesses in the following years. Some of the jobs are expected to disappear altogether. The expanding digitalisation can be seen as an example of the diffusion of innovations. The world has witnessed similar developments since the early years of industrialisation. Some of the sectors that will face the most disruptive changes are accounting, bookkeeping, and auditing. As much as 94 to 98 per cent of these jobs are at risk. The purpose of this study was to find out how digitalisation, automation of routines, robotics, and artificial intelligence are expected to affect the business structure, organisations, tasks, and empl…
Primi reperti in Sicilia su diffusione e biologia di Leptoglossus occidentalis Heidemann (Hetroptera: Coreidae), cimice americana dei semi delle coni…
2009
In this paper the first data on the distribution and biology of L. occidentalis in Sicily are reported; this bug, belonging to the family Coreidae, originates from North America, where it is regarded as a serious pest of conifer seed orchards. The first Sicilian specimens of L. occidentalis were found in September 2002 near Gangi (PA), while the first collecting data published until now refer to November 2003 in Niscemi (CL). The coreid is distributed in all Sicily provinces (30 collecting sites), from the sea level to 1.430 m a.s.l. on the mountains; it was collected on cones and plants of Pinus halepensis Miller, P. laricio Poiret, P. pinea L., P. nigra J.F.Arnold and Pseudotsuga menziesi…

LA FOTOCATALISI ETEROGENEA UTILIZZATA COME METODO PER LE SINTESI ORGANICHE SELETTIVE IN CONDIZIONI SPERIMENTALI BLANDE
2014
Nel corso di questi tre anni di Dottorato di Ricerca in “Tecnologie per la Sostenibilità ed il Risanamento Ambientale”, XXIV ciclo, presso il laboratorio di ricerca di fotocatalisi eterogenea “Schiavello-Grillone”, sono stati sviluppati processi innovativi per la produzione selettiva di specie organiche ad alto valore aggiunto, seguendo i principi della Chimica Verde; in particolare sono state studiate reazioni di ossidazione parziale di composti aromatici. La metodologia prevalentemente utilizzata è stata la fotocatalisi eterogenea mediante l’utilizzo del biossido di Titanio policristallino (TiO2) come fotocatalizzatore, utilizzato sospeso in soluzione acquosa o immobilizzato su supporti r…
