"Et occidetur virtute Domini Antichristus a Mikaele arcangelo". Paisaje y escatología en Sant Miquel de Llíria (s. XIV d. C.)
2015
El presente articulo intenta determinar las razones por las que el santuario de Sant Miquel de Llíria, uno de los más importantes de la actual provincia de Valencia, se consagró al arcàngel guerrero. Se estudia para ello la historia de su culto en Occidente, haciendo hincapié en aspectos como su relación con los lugares elevados y la frecuente proximidad de sus santuarios con aquellos dedicados a la Virgen. Atenderemos también a aspectos fundamentales del contexto histórico, como los movimientos de renovación espiritual medievales, la influencia del médico y teólogo Arnau de Vilanova en la Valencia de principios del siglo XIV y las profecías escatológicas vinculadas a la llegada del Anticri…
Lecciones de psicología: notas sobre la lectura nietzscheana de 'Humillados y ofendidos' de Dostoievski
2012
espanolE: Este texto, primera parte de un extenso estudio sobre la lectura nietzscheana de Humillados y ofendidos de F. Dostoievski, arranca con una reflexion sobre la actualidad del analisis de las relaciones entre ambos escritores como un reto que sigue abierto en la Nietzsche-Forschung. Desde los documentos que testimonian dicha lectura y sus efectos («mit dem grossten Respekt vor dem Kunstler Dostoiewsky»), se evidencia que hay que clarificar la concepcion del artista que aqui se manifiesta. las cartas de Nietzsche demuestran por otra parte que el filosofo valoro al escritor ruso sobre todo en cuanto psicologo, segundo tema a explicitar. los textos de E. M. de la Vogue sobre Dostoievski…
Phoenician maritime pioneering and Punic expansion: reconstructing trade and dietary patterns
2015
Perhaps the most significant legacy attributed to the Phoenicians was their mastery of the seas, which led them to establish the first grand commercial Mediterranean network, expanding from Lebanon to beyond the Pillars of Hercules between the 8th and 6th centuries BC. The Punic culture, which flourished in the central and western Mediterranean from Phoenician colonies, maintained the exceptional navigation skills of the Phoenicians, but developed into more settled and structured territories that allowed the communities to intensify their exploitation of Mediterranean resources. Their rise to prominence can be measured by the threat they posed to the Roman Republic, while the salvage of the…
Un’esperienza di rilevamento architettonico con tecniche integrate
2004
Lo studio esposto riguarda la sperimentazione sulle tecniche per il rilevamento e la rappresentazione di manufatti architettonici caratterizzati dalla presenza di una ricca decorazione scultorea. In particolare, è stata condotta una applicazione sulla parete di ingresso dell’Oratorio del SS. Rosario presso la chiesa di Santa Cita, nel centro storico di Palermo. Nel corso dello studio sono stati messi a confronto ed integrati i dati provenienti dal rilevamento diretto, topografico, fotogrammetrico, e da acquisizioni eseguite con laser a scansione. This paper is addressed to test suitable techniques for surveying and restitution of architectural surfaces decorated with free-form masses (i.e. …
3D mosaics survey: analysis of photogrammetric/computer vision approach in a metrological context
2016
The goal of the paper is evaluate photogrammetric/computer vision approach in a metrological context for 3D mosaics survey. The aim of the mosaics survey is the production of a full-scale representation (scale 1:1) useful for the documentation and for the restoration processes. In order to evaluate the optimal photogrammetric/computer vision workflow in this work three different surveys have been done for three mosaics with different size and location. Two of these are stored at Regional Archaeological Museum “Antonino Salinas” in Palermo (Italy) and the other one is stored at Regional Archaeological Museum “Baglio Anselmi” in Marsala (Italy). The research has allowed to show the potentiali…
Comparison of cartesian and lobe function Gaussian basis sets
1970
The lobe function and cartesian (spherical harmonic) gaussian are compared with reference to calculations for second-row atoms. Single and grouped gaussian basis sets which have been reported for cartesian functions are taken over directly to construct corresponding lobe function bases with identical sets of exponents and with lobe separations chosen by a scaling procedure. Total and orbital energies and SCF coefficients resulting from calculations on the second-row atoms using the two types of functions for both primitive and grouped gaussian basis sets are seen to be in excellent agreement, thereby emphasizing the essential equivalence of lobe functions and cartesian gaussians, at the ver…
Flux expressions and NEMD perturbations for models of semi-flexible molecules
2001
We derive energy and momentum flux expressions, for systems composed of a general class of semi-flexible molecules, in the Ciccotti-Ferrario-Ryckaert linear constraint formalism. According to this formalism, the whole set of Cartesian coordinates is divided into basic (independent) and secondary (dependent) subsets. It is found that energy and momentum flux vectors have a simple and general expression using both basic and secondary coordinates. In the case of non-equilibrium molecular dynamics, we give general and simple heat and shear flow algorithms, deriving the dissipative fluxes in the space of all Cartesian coordinates. In comparison with previous derivations for some models of flexib…
Nonlocal energy density functionals for low-energy nuclear structure
2014
We introduce a finite-range pseudopotential built as an expansion in derivatives up to next-to-next-to-next-to-leading order (N$^3$LO) and we calculate the corresponding nonlocal energy density functional (EDF). The coupling constants of the nonlocal EDF, for both finite nuclei and infinite nuclear matter, are expressed through the parameters of the pseudopotential. All central, spin-orbit, and tensor terms of the pseudopotential are derived both in the spherical-tensor and Cartesian representation. At next-to-leading order (NLO), we also derive relations between the nonlocal EDF expressed in the spherical-tensor and Cartesian formalism. Finally, a simplified version of the finite-range pse…
Fully Covariant and Conformal Formulation of the Z4 System Compared to the BSSN Formulation in Spherical Symmetry
2014
We have generalized a covariant and conformal version of the Z4 system of the Einstein equations by adopting a reference metric approach, that we denote as fCCZ4, well suited for curvilinear as well as Cartesian coordinates. We implement this formalism in spherical polar coordinates under the assumption of spherical symmetry using a partially-implicit Runge-Kutta (PIRK) method, without using any regularization scheme, and show that our code can evolve both vacuum and non-vacuum spacetimes without encountering instabilities. We have performed several tests and compared the Hamiltonian constraint violations of the fCCZ4 system, for different choices of certain free parameters, with these of B…
Partial wave decomposition of finite-range effective tensor interaction
2016
We perform a detailed analysis of the properties of the finite-range tensor term associated with the Gogny and M3Y effective interactions. In particular, by using a partial-wave decomposition of the equation of state of symmetric nuclear matter, we show how we can extract their tensor parameters directly from microscopic results based on bare nucleon-nucleon interactions. Furthermore, we show that the zero-range limit of both finite-range interactions has the form of the next-to-next-to-next-leading-order (N3LO) Skyrme pseudopotential, which thus constitutes a reliable approximation in the density range relevant for finite nuclei. Finally, we use Brueckner-Hartree-Fock results to fix the te…
