Riflessioni per una definizione di “prodotto agricolo sostenibile”
2021
Il presente lavoro si propone di riflettere circa i limiti che l’assenza di un’adeguata definizione di “prodotto sostenibile” comporta, tentando una sua ricostruzione pure alla luce di una più ampia analisi del principio di sostenibilità e della sua evoluzione nel corso degli ultimi decenni. L’assenza di un quadro normativo chiaro genera, infatti, incertezze pure in sede di trasmissione al consumatore delle scelte di sostenibilità assunte dalle imprese in ambito agroalimentare, non permettendo a tali soggetti di definire consapevolmente la propria dieta. Il rischio di informazioni ingannevoli e la difficoltà nell’identificare quando i comportamenti assunti siano il risultato di una politica…
Application of time-dependent many-body perturbation theory to excitation spectra of selected finite model systems
2016
In this thesis, an approximate method introduced to solve time-dependent many-body problems known as time-dependent many-body perturbation theory is studied. Many-body perturbation theory for interacting electrons and phonons is reviewed. In particular, the electron propagator G and an unconventional two-component phonon propagator, which satisfy coupled integral Dyson equations, are introduced. In practice, the associated integral kernels known as the electron Σ and phonon self-energies need to be approximated. The conserving approximations known as the Hartree (-Fock) and the first and second Born approximations, which respect the continuity equation between the electron density and curren…
A Service Model for Green Open Access in Finland – Why, What and How?
2017
Presentation in the ILIDE 2017 conference in Jasná, Slovakia. Presentation focuses on describing the centralized service model of green open access and how the open access goals set by EU and the Finnish Open Science and Research Initiative can be reached.

The Roadmap to Finnish Open Science and Research
2015
Finland published its open science roadmap at the end of November 2014. This roadmap is based on the work of the Open Science and Research Initiative (ATT), a cross-administrative initiative established by the Ministry of Education and Culture. The goal of this initiative is to promote open science and availability of information. Exploration of recent developments of open access in the EU shows that Finland is not among the leading countries in the EU. This paper focuses on the practical action plan of this roadmap and describes how the weakest part of Finnish open science, green open access is to be lifted at international top level.
Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
Spunti critici sull’aggiornamento della normativa europea in tema di qualità dell’aria
2022
This paper aims at presenting an argument in favour of the need for a prompt update of the European legislation on air quality, by taking its cue from the current situation in Italy. The paper starts by providing a definition of outdoor air pollution and by referring to the most influential Italian scientific studies on the main health risks connected. The perspective then shifts to the analysis of the relevant legislation at both European and national level in an attempt to systematically recompose the complex framework of plans and regulations adopted for the containment and prevention of outdoor pollution. In this framework, the analysis of the three infringement procedures opened agains…
Modeling the probability distribution of peak discharge for infiltrating hillslopes
2017
Hillslope response plays a fundamental role in the prediction of peak discharge at the basin outlet. The peak discharge for the critical duration of rainfall and its probability distribution are needed for designing urban infrastructure facilities. This study derives the probability distribution, denoted as GABS model, by coupling three models: (1) the Green-Ampt model for computing infiltration, (2) the kinematic wave model for computing discharge hydrograph from the hillslope, and (3) the intensity-duration-frequency (IDF) model for computing design rainfall intensity. The Hortonian mechanism for runoff generation is employed for computing the surface runoff hydrograph. Since the antecede…
Runoff coefficients to predict peak discharge at hillslope scale: A small contribution to theoretical hydrology
2018
The science of hydrology holds a central role in the field of environmental Earth science, being intimately connected to meteorology, climatology, hydrogeology and ecology. In particular, the knowledge of hillslope hydrology is fundamental for understanding the flood phenomenon, for predicting the peak discharge and its probability distribution, which is necessary in many practical applications (design of hydraulic structures, urban, extra-urban planning, etc.). Using different approaches, there have been a multitude of studies on the hydrologic response at hillslope scale. One approach for deriving the hillslope response utilizes, in a distributed form, the differential equations of unstea…
