"Un personaggio di fiaba generoso e gentile". O'Tama Kiyohara e l'amicizia con Mario ed Elisa Oliveri

2017

Il testo ricostruisce - anche attraverso alcuni documenti inediti - il quadro dei rapporti fra il poeta ed editore Mario Oliveri (1900-1963), lo scultore Vincenzo Ragusa e sua moglie, la pittrice O'Tama Kiyohara, dal 1925 sino al ritorno di O'Tama in Giappone, nel settembre 1932.

Enseñanza de las ciencias : revista de investigación y experiencias didácticas

2003

Se discuten algunas de las conclusiones de varios trabajos históricos recientes sobre Amedeo Avogadro y la teoría atómica del siglo XIX. A través de pequeños extractos de publicaciones famosas de Avogadro, se analizan las características principales de sus aportaciones a la teoría atómica del siglo XIX. También se analizan los principales métodos de cálculo de pesos atómicos de esos años y se discute el papel de las ideas de Avogadro en este tema. Estas conclusiones se contrastan con la imagen que actualmente los libros de texto dan acerca de este autor. Finalmente, esta última comparación conduce a una discusión sobre el papel de la historia de la ciencia en los libros de texto. This paper…

A Realistic Proposal for the Observation of Zeno Phenomena in the Dynamics of Trapped Ions

2001

A realistic experimental scheme for the observation of a continuous measurement Quantum Zeno Effect in the contest of single trapped ions is proposed. Our method relies on the nonlinearities characterizing the ionic Rabi frequency far from the Lamb-Dicke regime.

A fractional order theory of poroelasticity

2019

Abstract We introduce a time memory formalism in the flux-pressure constitutive relation, ruling the fluid diffusion phenomenon occurring in several classes of porous media. The resulting flux-pressure law is adopted into the Biot’s formulation of the poroelasticity problem. The time memory formalism, useful to capture non-Darcy behavior, is modeled by the Caputo’s fractional derivative. We show that the time-evolution of both the degree of settlement and the pressure field is strongly influenced by the order of Caputo’s fractional derivative. Also a numerical experiment aiming at simulating the confined compression test poroelasticity problem of a sand sample is performed. In such a case, …

La memoria de los verdugos de 1936 y la cultura de la impuni(bili)dad en la democracia posfranquista

2020

UIDB/04666/2020 UIDP/04666/2020 Este texto se interesa por los efectos de la producción académica sobre la construcción social del victimario, y se centra en el caso de los victimarios de la guerra española de 1936 y su estatus en la cultura de la democracia posfranquista. Escoge dos obras de especialistas dirigidas al público amplio y rastrea a partir de ellas cómo el tratamiento de los victimarios se encuentra predefinido por un marco que exonera de partida a determinados posibles perpetradores al figurar en la nómina de intelectuales y artistas que conforman el canon cultural del siglo XX. El enfoque alternativo que propone consiste en combinar una hermenéutica de los testimonios de posi…

Recuperación y reintroducción de Marsilea quadrifolia en los arrozales del delta del Ebro (Tarragona, España).

2001

ESTRELLES, E., IBARS, A. M., IRANZO, J. & MORALES, F. 2001. Recuperation and reintroduction of Marsilea quadrifolia in the rice fields of the Ebro's Delta (Tarragona, Spain). Bot. Complutensis 25: 251-259. Marsilea quadrifolia has got to be a extincted species in the Ebro's Delta. In this work the process of recovery of the species is described by sporocarps localization in the soil, germination of the same ones in the laboratory and cultivation in pots of the obtained sporelings, from which we proceeded to the reintroduction of Marsilea quadrifolia in old rice fields inside the land of the Natural Park, as well as the conservation measures ex situ applied on this species that tradition…

Finite element method on fractional visco-elastic frames

2016

Viscoelastic behavior is defined by fractional operators.Quasi static FEM analysis of frames with fractional constitutive law is performed.FEM solution is decoupled into a set of fractional Kelvin Voigt elements.Proposed approach could be easily integrated in existing FEM codes. In this study the Finite Element Method (FEM) on viscoelastic frames is presented. It is assumed that the Creep function of the constituent material is of power law type, as a consequence the local constitutive law is ruled by fractional operators. The Euler Bernoulli beam and the FEM for the frames are introduced. It is shown that the whole system is ruled by a set of coupled fractional differential equations. In q…
