    Hippolytus’ songs show that, even when taking from Aeschylus or Sophocles, Euripides is always attempting innovative solutions. This play belongs to an initial stage of the Euripidean work, but it probably marks the starting point in the evolution of his poetry within the framework of the so-called “New music”

    openThe thesis describes the 1964 coup d’etat in Brazil analyzing its causes and consequences. It focuses than, on the role and the influence that the United States had in this event as well as on the strategies which they adopted to influence the course of events, particularly it focusses on the so-called “Operation Brother Sam”.The thesis describes the 1964 coup d’etat in Brazil analyzing its causes and consequences.

    The University of Padova has a long tradition of studies on ancient Greek tragedy. On September 13th, 2016, under the supervision of prof. Davide Susanetti, Mattia De Poli organised the seminar \u201cEuripide. Storie, testi, drammaturgia\u201d: a group of young scholars who spent at least a part of their education at this academic institution tried to face the challenge and offer new contributions on the Euripidean drama. This book collects almost all of them, with some additions, offering a range of perspectives: cultural, anthropological, philological, dramaturgical

    The gene mapping of Senegalese sole (S. senegalensis)

    The Senegalese sole (S. senegalensis) is a common flatfish, distributed over the eastern Atlantic coast from the Northern part of Senegal. Senegalese sole aquaculture has aroused great interest in the marine aquaculture in Spain and Portugal because of its relatively rapid growth rate, but it presents limits due to the poor reproduction of captive breeders in many facilities. In fact gonad development during sexual maturation results in major growth reduction, and increased susceptibility to diseases (Felip et al., 2006). Senegalese sole has 42 chromosomes and an XX/XY chromosome system for sex determination, while related species show the ZZ/ZW system. In S. senegalensis, these problems are aggravated because of the lack of knowledge concerning sex. This study fits into a detailed project of Senegalese sole knowledge, promoted by University of Cádiz, providing new information about the karyotype characterization, the chromosome structure of certain genes involved in sex determination and sexual differentiation processes, which may be relevant for improving the commercial production of this species. This piece of information not only helps to understand the development and evolutionary mechanism in vertebrates, but will also contribute to improving the production of target species for aquaculture. For this purpose, several bacterial artificial chromosome (BAC) clones that contain candidate genes involved in such processes (Vitellogenin, Otospiralin, R-spondin-1, Steroidogenic Factor1 and Tetkin-2) were analyzed and compared, where possible, with the same genes in other species. In this study it was possible to describe a part of those four genes, using 3’ RACE method. The BAC-FISH results showed the position of different genes in different chromosome, to improve the knowledge of Senegalese sole karyotype. In particular, the localization of steroidogenic factor 1 (SF1) in the chromosome 1 that is involved in the sex determination

    Influence of the Coulomb potential on above-threshold ionization: a quantum-orbit analysis beyond the strong-field approximation

    Get PDF
    We perform a detailed analysis of how the interplay between the residual binding potential and a strong laser field influences above-threshold ionization (ATI), employing a semi-analytical, Coulomb-corrected strong-field approximation (SFA) in which the Coulomb potential is incorporated in the electron propagation in the continuum. We find that the Coulomb interaction lifts the degeneracy of some SFA trajectories, and we identify a set of orbits which, for high enough photoelectron energies, may be associated with rescattering. Furthermore, by performing a direct comparison with the standard SFA, we show that several features in the ATI spectra can be traced back to the influence of the Coulomb potential on different electron trajectories. These features include a decrease in the contrast, a shift towards lower energies in the interference substructure, and an overall increase in the photoelectron yield. All features encountered exhibit a very good agreement with the \emph{ab initio} solution of the time-dependent Schr\"odinger equation.Comment: 12 pages, 10 figure
