Understanding the Mechanism of the Intramolecular Stetter Reaction. A DFT Study
2012
The mechanism of the N-heterocyclic carbene (NHC)-catalyzed intramolecular Stetter reaction of salicylaldehyde 1 to yield chromanone 3 has been theoretically studied at the B3LYP/6-31G** level. This NHC-catalyzed reaction takes place through six elementary steps, which involve: (i) formation of the Breslow intermediate IN2; (ii) an intramolecular Michael-Type addition in IN2 to form the new C-C s bond; and (iii) extrusion of the NHC catalyst from the Michael adduct to yield chromanone 3. Analysis of the relative free energies in toluene indicates that while formation of Breslow intermediate IN2 involves the rate-determining step of the catalytic process, the intramolecular Michael-type addi…
Michael Monroe – miesrepresentaation armahtaja
2013
Tutkimukseni käsittelee suomalaista taiteilijaa, artistia, elävää rock-legenda Michael Monroeta ja hänen visuaalisuuttaan uudenlaisena miesrepresentaationa. Michael Monroe on otollinen tutkimuskohde, sillä hänen ainutlaatuinen ja rohkea heteronormatiivisia rajoja rikkova tyylinsä on tuonut esille miehuuden feminiinisen puolen.

Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti
2021
In this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chroma…

Aristocracia alada, adalides del rey del Cielo. Ángeles militares en la pintura barroca americana
2016
El presente trabajo aborda el estudio de las imágenes de los ángeles militares en los virreinatos americanos y su interpretación a partir de la función cultural de las imágenes. Para ello se analizan las distintas tipologías visuales del arcángel san Miguel en el virreinato de Nueva España y su uso regiopolítico, la definición beligerante del resto de ángeles en la tradición teológica y la imagen de los conocidos como arcángeles arcabuceros. Identifica la tradición bélica del lenguaje posterior al concilio de Trento y, en el caso de los arcángeles arcabuceros, defiende su vinculación con la fiesta barroca. The present work focuses on the study of images of military angels in American Coloni…

I Vari componenti d'architettura (1766) di Michele Vella
2013
Michele Vella, sculptor and antiquarian of Agrigento, born in nearby Raffadali, is known through chronicles and accounts of foreign travelers who visited "the city of temples" duringin the last few decades of the eighteenth century. Prior to devote himself to the study of ancient Agrigento and to become a "guide" of famous visitors, such as Goethe, he began to develop a treatise on architecture dedicated in 1766 to the bishop Andrea Lucchesi Palli. The unfinished manuscript titled Vari Componimenti d'Architettura is now located at the Library Lucchesiana of Agrigento.
Law, Plans and Practical Rartionality
2012
There is, according to many contemporary jurisprudential theories, a tight relationship between law and practical rationality: the law gives us, or at least it purports to give us, reasons for action. In his book, Legality (2011), Scott J. Shapiro puts forward what at first glance appears to be a new view in this vein. Shapiro calls it the “Planning Theory” of law; it provides an account of what the law is in terms of a particular kind of reasons: plans (a notion moulded, in his work in the philosophy of action, by Michael E. Bratman). In this paper, I provide a reconstruction of the Planning Theory as a view of the relationships between law and practical rationality, and I point to some fu…
