Circular economy and agritourism: a sustainable behavioral model for tourists and farmers in the post-COVID era.
2023
Introduction: In recent years, issues related to environmental and ecosystem protection have been given greater consideration than in the past. The goal of adopting sustainable development models is vigorously pursued in the European Union and is reflected concretely in the new Common Agricultural Policy 20232027. The circular economy can certainly be an emerging economic response that can eectively replace growth models centered on a linear view. Agriculture and tourism are two crucial sectors where the “green transition” should be encouraged to help achieve sustainability goals through economic circularity. Agritourism’s activity may be relevant in contributing to a behavioral change based…
Economical evaluation of ecological benefits of the demand side management
2014
Environmental pollution and over-exploitation of non-renewable sources to find energy are current topics for the modern world that is now at having to deal with several issues such as the greenhouse effect, acid rain and climate change. In this study, the economical estimate of the savings in carbon dioxide obtained with a careful management of electrical loads is presented. Four particular scenarios are designed as case studies: Italy, France, United Kingdom and Germany. A comparison is presented with a similar study, made in 2007, when green energies were not yet very developed.
Crescere/Svilupparsi. Teorie e rappresentazioni fra mondo antico e scienze della vita contemporanee

Il SicaniLab: Laboratorio di Sviluppo Locale
2017
Il SicaniLab, Laboratorio di Sviluppo Locale dei Sicani e della Valle del Platani, è uno dei due laboratori del “Polo Universitario di Ricerca di Bivona e Santo Stefano Quisquina per l’energia, l’ambiente e le risorse del territorio”, la cui responsabilità scientifica affidata al prof. Maurizio Carta, ed è composto da un gruppo multidisciplinare che opera nel campo dell’urbanistica, dell’economia, della storia dell’arte e del turismo in forma coordinata e integrata.
Il territorio dei Monti Sicani. Il sistema delle risorse territoriali per l’attivazione di politiche di sviluppo locale
2015
Il contributo presenta i primi risultati della ricerca – condotta nell’ambito del Laboratorio di Sviluppo Locale del Polo Universitario di Ricerca di Bivona e Santo Stefano Quisquina per l’energia, l’ambiente e le risorse del territorio1, ed affidata alla responsabilità scientifica del prof. Maurizio Carta – relativa all’interpretazione delle identità del territorio Sicano e alle opportunità di sviluppo da attivare attraverso la definizione di strategie fondate sulla dimensione rurale e culturale e indirizzate alla sperimentazione del modello smart land. La ricerca, che si inserisce nell’ambito dell’interesse ministeriale sulle Aree Interne, è finalizzata alla individuazione di sistemi rura…
[Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.]
2014
The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching.A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion.In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the…
Hysteretic Systems Subjected to Delta Correlated Input
1994
The paper deals with the evaluation of the probabilistic response of a single degree of freedom elastic-perfectly plastic system subjected to a delta correlated input process. The probabilistic characterisation of the response is here obtained by considering the accumulated plastic deformations as a compound homogeneous Poisson process independent of the external input. In this case the former can be considered as an external noise acting on the linear system. A closed form solution is also obtained and the analytic expression is compared with the customary Monte-Carlo method.
VAPOR-LIQUID EQUILIBRIUM CALCULATIONS USING THE TOPOLOGICAL TREATMENT OF MIXTURES.
1983
The Topological Treatment of mixtures is applied to several kinds of binary mixtures to obtain VLE diagrams. The excess Gibbs free energy, gE, is calculated as the product of a topological vector and an information vector. The pure compound topological description were obtained following the DARC system rules. A weighting function was introduced to obtain the topological description of a mixture. The information vector is calculated from experimental data. It is shown that for binary mixtures alcohol-alkane, the components of this vector varies linearly with the average number of carbon atoms of chemical compounds. This relationship allows prediction of the VLE diagram for any other system …
On the spectrum of semi-classical Witten-Laplacians and Schrödinger operators in large dimension
2005
We investigate the low-lying spectrum of Witten–Laplacians on forms of arbitrary degree in the semi-classical limit and uniformly in the space dimension. We show that under suitable assumptions implying that the phase function has a unique local minimum one obtains a number of clusters of discrete eigenvalues at the bottom of the spectrum. Moreover, we are able to count the number of eigenvalues in each cluster. We apply our results to certain sequences of Schrodinger operators having strictly convex potentials and show that some well-known results of semi-classical analysis hold also uniformly in the dimension.
