Three-dimensional geometrical models of the inguinal region. Towards a new stereology.
2003
In this work we studied the inguinal-abdominal region and the inguinal canal using three-dimensional geometrical models. We built the models through computer aided geometric modeling techniques on the basis of observations during real dissections, operations and diagnostic medical imaging. The obtained models show in a complete modular synthesis and with a schematic iconology the structural organization of the anatomical districts in a logic sequence of layers and topographic and spatial relationships among its components. The models represent an amazing support to anatomy and clinical anatomy for teaching and research purposes on organogenesis, surgery and diagnosis.

«Moderni e Antichi»: la vitalità e la persistenza della cultura umanistica nella tradizione occidentale
2022
Questa rassegna trae spunto dalla pubblicazione dei primi tre fascicoli della nuova serie della rivista «Moderni e Antichi. Quaderni del Centro di Studi sul Classicismo diretti da Roberto Cardini», pubblicati fra il 2019 e il 2021, a cura del Centro di Studi sul Classicismo di Prato, dalle Edizioni Polistampa di Firenze. This review is inspired by the publication of the first three issues of the new series of magazine «Moderni e Antichi. Papers of the Center for Studies on Classicism directed by Roberto Cardini», published between 2019 and 2021, edited by the Center for Studies on Classicism of Prato, by Edizioni Polistampa from Florence.
Los ritmos y la rima de la versificación goetheana en las versiones métricas del Fausto en español
2013
The few translators who have attempted a Spanish verse translation of Goethe’s Faust for the most part fail to do justice to the metrical diversity of Goethe’s play and therefore they either altogether give up the idea of rendering Goethe’s play in poetry, e.g. Pedro Gálvez in 1984, or they create a traditionalist Spanish Faust poem with excessive liberties regarding its content, like, in 1882, Teodoro Llorente. Others have tried to fit Goethe’s verse in the Procrustean bed of unrhymed endecasílabos, which has forced them to abridge the original text in numerous passages (Valverde 1963). Moreover, some authors, such as Valverde and Silvetti Paz (1970), translate some passages of Goethe’s ma…
Fractal geometry of higher derivative gravity
2019
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite operators. We use these results to deduce the fractal dimensions of such hypersurfaces embedded in a quantum spacetime at very small distances.

Il miglioramento energetico nel recupero degli edifici storici. Applicazione al patrimonio architettonico palermitano
L'architettura storica può assumere un ruolo rilevante nel raggiungimento degli obiettivi europei di efficienza energetica per il settore edile, obiettivi che, tuttavia, devono essere compatibili con la conservazione del patrimonio storico e del suo valore culturale. A tal fine è necessario far riferimento ai caratteri specifici dell'architettura storica e alla sua dimensione locale. La presente tesi, sulla base di tale assunto, esamina le prestazioni energetiche degli edifici storici e il loro potenziale miglioramento, concentrandosi sul patrimonio architettonico di Palermo, caso di studio significativo per l'area mediterranea. La ricerca, condotta con riferimento sia alla scala urbana sia…
Robust Ergonomic Virtual Design
2009
Since early development phases of a new industrial product, realistic simulations can be performed in virtual environment to study the human-machine interaction. In a virtual lab it is possible to make experiments to assess the ergonomics of the new product with manikins simulating the human body, and dealing with the problem of anthropometrical variation. Although such sophisticated tools are available, there is still need of a methodo-logical framework aimed at efficiently organizing the experiments in virtual lab. This paper provides an overview of the Robust Ergonomic Virtual Design (REVD), a methodology developed by the authors in the course of the last years. It allows obtaining produ…
Thermal degradation of long-chain polyunsatured fatty acids during deodorization of fish oil
2006
International audience; Long-chain polyunsaturated fatty acids (LC-PUFA) of the n-3 series, particularly eicosapentaenoic (EPA) and docosahexaenoic (DHA) acid, have specific activities especially in the functionality of the central nervous system. Due to the occurrence of numerous methylene-interrupted ethylenic double bonds, these fatty acids are very sensitive to air (oxygen) and temperature. Non-volatile degradation products, which include polymers, cyclic fatty acid monomers (CFAM) and geometrical isomers of EPA and DHA, were evaluated in fish oil samples obtained by deodorization under vacuum of semi-refined fish oil at 180, 220 and 250 °C. Polymers are the major degradation products g…
Independent Geometrical Control of Spin and Charge Resistances in Curved Spintronics
2019
Spintronic devices operating with pure spin currents represent a new paradigm in nanoelectronics, with higher energy efficiency and lower dissipation as compared to charge currents. This technology, however, will be viable only if the amount of spin current diffusing in a nanochannel can be tuned on demand while guaranteeing electrical compatibility with other device elements, to which it should be integrated in high-density three-dimensional architectures. Here, we address these two crucial milestones and demonstrate that pure spin currents can effectively propagate in metallic nanochannels with a three-dimensional curved geometry. Remarkably, the geometric design of the nanochannels can b…
