Constructing social Europe through European cultural heritage
2021
The political and economic crises of the recent decades as well as the new changes brought on by globalization and digitalization have contributed to exacerbate social inequalities and injustice and revealed different social realities in Europe. The EU increasingly deals with social issues in its cultural and heritage policy. In this article, we explore the construction of this social dimension and advance the concept of 'social Europe' by exploring its cultural aspect based on our analysis of a recent EU heritage action, the European Heritage Label. In this action, the narrations of the European past and the attempts to foster common cultural heritage in Europe function as building blocks …
Governance della crisi e importanza del territorio per lo sviluppo regionale
2012
The aim of this paper is a reflection on the role of space in the processes of economic change. Starting in the United States the financial and economic crisis infected Europe after 2007. A wider debate on the current differential role of governments in the U.S. and Europe in addressing the crisis has emerged. The bailout programs in the U.S. have made reference to a unitary and homogeneous reference frame in the presence of a central bank whose broad mandate includes development goals. Europe, instead, has shown a different scenario and the same financial integration project depends on the complex relationship between individuals and the community, national sovereignty and increasingly bin…

A Theoretical and Experimental Investigation of the Spectroscopic Properties of a DNA-Intercalator Salphen-Type ZnIIComplex
2014
The photophysical and DNA-binding properties of the cationic zinc(II) complex of 5-triethylammonium methyl salicylidene ortho-phenylenediiminato (ZnL 2 + ) were investi- gated by a combination of experimental and theoretical methods. DFT calculations were performed on both the ground and the first excited states of ZnL 2 + and on its possi- ble mono- and dioxidation products, both in vacuo and in selected solvents mimicked by the polarizable continuum model. Comparison of the calculated absorption and fluores- cence transitions with the corresponding experimental data led to the conclusion that visible light induces a two-elec- tron photooxidation process located on the phenylenediimi- nato…
BODIPY atropisomer interconversion, face discrimination, and superstructure appending
2016
International audience; A strategy was developed to append sterically hindered apical pickets on both faces of the BODIPY platform to prevent stacking and aggregation. Ortho-substitution of both the meso-phenyl ring and the boron-bound catechol affords the right directionality to append pickets, achieve face discrimination, featuring two inter-convertible atropisomers, and is reminiscent of the picket-fence strategy in porphyrins.
Towards controlling PCDD/F production in a multi-fuel fired BFB boiler using two sulfur addition strategies
2014
Abstract PCDD/F abatement strategies – sulfur pellet addition and peat co-combustion – were tested for a BFB boiler facility utilizing SRF-bark-sludge as fuel. In this paper chemical and physical analyses of electrostatic precipitator (ESP) fly ashes were used to explain the differences in the performance of these strategies. These analyses revealed a difference between the coarse and fine fly ashes collected in the ESP. Chemical analysis of the fine fly ashes revealed high concentration of easily volatilized elements while the SEM micrographs showed that fine ash are composed of clusters of spherical particles, thereby leading to a conclusion that fine ashes were originally in a gas phase …
A Long Journey into the Investigation of the Structure–Dynamics–Function Paradigm in Proteins through the Activities of the Palermo Biophysics Group
2022
An overview of the biophysics activity at the Department of Physics and Chemistry Emilio Segrè of the University of Palermo is given. For forty years, the focus of the research has been on the protein structure–dynamics–function paradigm, with the aim of understanding the molecular basis of the relevant mechanisms and the key role of solvent. At least three research lines are identified; the main results obtained in collaboration with other groups in Italy and abroad are presented. This review is dedicated to the memory of Professors Massimo Ugo Palma, Maria Beatrice Palma Vittorelli, and Lorenzo Cordone, which were the founders of the Palermo School of Biophysics. We all have been, directl…

un antico sistema di drenaggio sotterraneo. i "cunicoli borbonici di Petralia Sottana (Sicilia)
2017
Lo studio riguarda un intervento geotecnico in sotterraneo realizzato diversi secoli fa la cui esecuzione ha influenzato positivamente le condizioni di stabilità dei versanti contigui a una linea di impluvio che, attraversando il centro storico del comune di Petralia Sottana, ne minacciava la sicurezza.
