Dal quadro al modello virtuale: una ricostruzione tridimensionale interattiva dell'Albergheria di Palermo nel 1749

2011

This study suggests a virtual three-dimensional reconstruction of a large urban portion of Palermo Historical Centre modelled on an isometrical view of the 17th century entitled Descrizzione del distretto parrocchiale dell’Albergheria fatta l’anno 1749. It is a painting on canvas that has been kept inside the parish of S.Nicolò all’Albergheria, and which in latter days has been taken by the Museum of Palermo Diocese where it is presently exposed to the public. The work presents different levels of interest for the reading of urban ancient morphology which now has disappeared and for the right information of road textures, blocks and monuments represented there. The digital elaboration that …

Optimisation of chromatographic resolution using objective functions including both time and spectral information.

2014

The optimisation of the resolution in high-performance liquid chromatography is traditionally performed attending only to the time information. However, even in the optimal conditions, some peak pairs may remain unresolved. Such incomplete resolution can be still accomplished by deconvolution, which can be carried out with more guarantees of success by including spectral information. In this work, two-way chromatographic objective functions (COFs) that incorporate both time and spectral information were tested, based on the peak purity (analyte peak fraction free of overlapping) and the multivariate selectivity (figure of merit derived from the net analyte signal) concepts. These COFs are s…

No-core configuration-interaction model for the isospin- and angular-momentum-projected states

2016

[Background] Single-reference density functional theory is very successful in reproducing bulk nuclear properties like binding energies, radii, or quadrupole moments throughout the entire periodic table. Its extension to the multi-reference level allows for restoring symmetries and, in turn, for calculating transition rates. [Purpose] We propose a new no-core-configuration-interaction (NCCI) model treating properly isospin and rotational symmetries. The model is applicable to any nucleus irrespective of its mass and neutron- and proton-number parity. It properly includes polarization effects caused by an interplay between the long- and short-range forces acting in the atomic nucleus. [Metho…

Chemical constituents of the root wood of Erythrina sacleuxii and determination of the absolute configuration of suberectin

2020

Phytochemical investigation on the root wood of Erythrina sacleuxii (Leguminosae) led to the isolation of nine secondary metabolites (1-9). Compound 1 was isolated from the genus Erythrina for the first time. The pure compounds were identified on the basis of comprehensive spectroscopic and spectrometric analyses, while their absolute configurations were determined based on chiroptical measurements. Compounds 5 and 6 showed weak antifungal activity against Pyricularia oryzae with MIC values of 20 µg/mL.

An In Vitro Phantom Study on the Role of the Bird-Beak Configuration in Endograft Infolding in the Aortic Arch.

2015

Purpose: To assess endograft infolding for excessive bird-beak configurations in the aortic arch in relation to hemodynamic variables by quantifying device displacement and rotation of oversized stent-grafts deployed in a phantom model. Methods: A patient-specific, compliant, phantom pulsatile flow model was reconstructed from a patient who presented with collapse of a Gore TAG thoracic endoprosthesis. Device infolding was measured under different flow and pressure conditions for 3 protrusion extensions (13, 19, and 24 mm) of the bird-beak configuration resulting from 2 TAG endografts with oversizing of 11% and 45%, respectively. Results: The bird-beak configuration with the greatest protr…

Figures of equilibrium in close binary systems

1992

The equilibrium configurations of close binary systems are analyzed. The autogravitational, centrifugal and tidal potentials are expanded in Clairaut's coordinates. From the set of the total potential angular terms an integral equations system is derived. The reduction of them to ordinary differential equations and the determination of the boundary conditions allow a formulation of the problem in terms of a single variable.

Estela antropomorfa con inscripción ibérica del Mas de Barberán (Nogueruelas, Teruel)

1998

The subject of this paper is a little known Iberian gravestele from Nogueruelas (Teruel). The find-spot, the Mas de Barberán, is close to the boundary with Cortes de Arenoso (Castellón). The piece is one of a class of stele charactised by figurative decoration and an inscription. The discussion focusses on the anthropomorphic shape of the piece, its iconography —the disk-cuirass—, and the inscription.

Small anthropomorphic figurines in clay at Gipka neolithic settlements:

2005

Miniature Neolithic figurines in clay are a special topic of research. This especially concerns areas where their representation has so far been poor. While carrying out archaeological excavations in Northern Kurzeme, the north west coastal dune yone of Riga Bay, a ritual-like complex was recovered at Gipka A site belonging to the local Culture of Pit Ceramics. It consists of several large and smaller fireplaces and pits, with the finds of fragmentary clay figurines recovered under the palisade that surrounded the settlement. The head and body of the miniature anthropomorphic figurines in clay have original modelling. It is possible to single out two types of figurine: with rather broad che…

The production of terracotta figurines in the city of Augustodunum. Presentation of the latest research.

2018

National audience; Les opérations archéologiques menées depuis 2013 sur le secteur de la Genetoye ont permis de mettre au jour un mobilier de coroplastie important et de bonne qualité. Ces figurines ont constitué le point de départ de la réalisation d’un mémoire universitaire (ANDROUIN 2017) et d’une nouvelle approche de ces objets. Nous présenterons ici les derniers résultats concernant l’étude des productions des figurines en terre cuite gallo-romaines dans l’agglomération d’Augustodunum.
