Leon Battista Alberti e il "doctus artifex"
2011
Attraverso l’esame della nozione di “artista dotto” - tracciata dallo stesso Alberti nel De pictura – si avvia un’indagine sui destinatari dei trattati albertiani relativi alle arti figurative. Infatti il lettore di Alberti non è più l’artigiano che nel manuale cerca regole operative, ma è un personaggio più colto che deve avere competenze in ambiti differenti (dal latino alla musica, dalla matematica alla retorica). Probabilmente i veri destinatari si potrebbero individuare tra i dotti uditori delle corti signorili, a cui l’umanista aveva già rivolto altre opere (il Philodoxeos, il De equo animante, il Teogenio, i Ludi Matematici). Pertanto un nuovo tipo di lettore si affaccia nel panorama…
Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation
2019
In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…
Ohjaajien toiminta elintapamuutosten tukemisessa tyypin 2 diabeteksen ehkäisyn ryhmäohjauksessa
2016
The purpose of the study was to describe the supervisors’ action in the support of changing one’s living habits in two weight management groups in the type 2 diabetes prevention program. The data consists of 17 video-recorded 90-minute “Small decision a day” weight management group counselling sessions of two groups with 10 and 20 participants in the years 2004-2005. The supervisors’ talk was analyzed with the deductive analysis from five teaching perspectives including theirs beliefs, intentions and actions. The transtheoretical change model and the participants’ talk were analyzed with the inductive analysis. Quantitative methods were used to give more information about the counselling se…
Spin Crossover in Fe(II)–M(II) Cyanoheterobimetallic Frameworks (M = Ni, Pd, Pt) with 2-Substituted Pyrazines
2016
Discovery of spin-crossover (SCO) behavior in the family of Fe(II)-based Hofmann clathrates has led to a "new rush" in the field of bistable molecular materials. To date this class of SCO complexes is represented by several dozens of individual compounds, and areas of their potential application steadily increase. Starting from Fe(2+), square planar tetracyanometalates M(II)(CN)4(2-) (M(II) = Ni, Pd, Pt) and 2-substituted pyrazines Xpz (X = Cl, Me, I) as coligands we obtained a series of nine new Hofmann clathrate-like coordination frameworks. X-ray diffraction reveals that in these complexes Fe(II) ion has a pseudo-octahedral coordination environment supported by four μ4-tetracyanometallat…
A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era
2023
Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…

Text Linguistics and Classical Studies: Dressler and de Beaugrande’s Procedural Approach
2017
The work represents a significant scientific advancement on text linguistics from three different viewpoints. The first chapter provides an overview of the history of text linguistics from a broader perspective than usual, offering a complete reference framework. The second chapter presents the procedural approach to the study of text linguistics in a concise way, including a critical comparison with other perspectives. The third chapter constructs a very unusual bridge between theoretical linguistics and classical studies in that it takes a literary text in Latin from the early imperial period as its case study. This combination is rare, as theoretical linguists are usually oriented to mod…
Natural occupation numbers: When do they vanish?
2013
The non-vanishing of the natural orbital (NO) occupation numbers of the one-particle density matrix of many-body systems has important consequences for the existence of a density matrix-potential mapping for nonlocal potentials in reduced density matrix functional theory and for the validity of the extended Koopmans’ theorem. On the basis of Weyl’s theorem we give a connection between the differentiability properties of the ground state wavefunction and the rate at which the natural occupations approach zero when ordered as a descending series. We show, in particular, that the presence of a Coulomb cusp in the wavefunction leads, in general, to a power law decay of the natural occupations, …
Analytic density-functionals with initial-state dependence and memory
2013
We analytically construct the wave function that, for a given initial state, produces a prescribed density for a quantum ring with two noninteracting particles in a singlet state. In this case the initial state is completely determined by the initial density, the initial time derivative of the density and a single integer that characterizes the (angular) momentum of the system. We then give an exact analytic expression for the exchange-correlation potential that relates two noninteracting systems with different initial states. This is used to demonstrate how the Kohn-Sham procedure predicts the density of a reference system without the need of solving the reference system’s Schrodinger equa…
