    This thesis offers a new critical edition of Sophocles’ fragmentary Tyro, with introduction, testimonies, an Italian translation and a complete commentary. Indeed, still today there is no edition exclusively devoted to Sophocles’ Tyro, while the latest commented edition is that by A.C. Pearson (The Fragments of Sophocles), including all of Sophocles’ fragments, and dating back to 1917. A study on Sophocles’ Tyro cannot overlook the problems specifically related to the play, and the difficulties in editing a lost tragedy preserved by indirect fragments. According to the ancient scholia and the Byzantine grammarians and lexicographers, Sophocles wrote two plays with this name. Unfortunately, the only indirectly-preserved fragments (except for a doubtful papyrus) are slight and short, and some of them are uncertainly attributed; this picture does not allow a clear distinction between the two Tyro, that is whether they were originally conceived as different tragedies or the second was a revision of the first. The available material, considered together with the ambiguous mythological sources and the figurative and dramaturgical evidence, allows only a speculative and incomplete restoration of the plot(s). I tackle the mythological background, iconographic and dramaturgical testimonies, homonymous title, plot, characters and chronology – with a specific focus on the second Tyro – in the general introduction, where I also clarify my methodological approach. Afterwards, I consider and analyse separately the 19 surviving fragments of Sophocles’ Tyro included in my edition. The fragments’ text is based on the autopsy of all the manuscripts, which led me to reconsider some of the previous editors’ choices. Finally, the commentary investigates some textual, exegetical, lexical, stylistic, metrical-rhythmical and dramaturgical aspects, explaining the context of the transmission of the examined fragments, their possible interpretation and their hypothetical re-contextualization within the play

    Denote by "frF" the multivalued mapping defined as the boundary of F. In the paper, in the setting T topological space and X is a topological linear space, the author studies the connection existing between the lower [respectively, upper] semicontinuity of the multivalued mapping F, and the lower [respectively, upper] semicontinuity of "frF". This paper can be seen as an extension of a previous work by the author and F. Papalini

    Emerging Issues in Sales Management. New perspectives to research on sales studies

    No full text
    Sales have been the subject of academic studies since the second half of the twentieth century but they were still held to be non strategic and marginal, as reflected by the scarce amount of academic works published on the matter. This has marked a gap between scholars and operational practices. Only in the last decade, as new marketing researches and theoretical models were added, has academics’ interest towards sales management arisen. It is relevant to debate on what emerges from the work of some academics who underline the urgency to address more research from scholars on sales and, at the same time, to consider the growing needs of companies, so as to fill the gap between academic and corporate realities. In this book the author, with different approaches to theoretical analysis, intends to address and explore the many trends that emerge from the academic literature on sales management

    Analysis of the chaotic behavior of the lower hybrid wave propagation in magnetised plasma by Hamiltonian theory

    No full text
    licensee MDPI, Basel, Switzerland.The Hamiltonian character of the ray tracing equations describing the propagation of the Lower Hybrid Wave (LHW) in a magnetic confined plasma device (tokamak) is investigated in order to study the evolution of the parallel wave number along the propagation path. The chaotic diffusion of the “time-averaged” parallel wave number at higher values (with respect to that launched by the antenna at the plasma edge) has been evaluated, in order to find an explanation of the filling of the spectral gap (Fisch, 1987) by “Hamiltonian chaos” in the Lower Hybrid Current Drive (LHCD) experiments (Fisch, 1978). The present work shows that the increase of the parallel wave number n‖ due to toroidal effects, in the case of the typical plasma parameters of the Frascati Tokamak Upgrade (FTU) experiment, is insufficient to explain the filling of the spectral gap, and the consequent current drive and another mechanism must come into play to justify the wave absorption by Landau damping. Analytical calculations have been supplemented by a numerical algorithm based on the symplectic integration of the ray equations implemented in a ray tracing code, in order to preserve exactly the symplectic character of a Hamiltonian flow. © 2016 by the author

Conclusione.ABSTRACT: The role of the Cardinals in the Apostolic Constitution Pastor Bonus on the Roman CuriaThe Cardinals are the main collaborators of the Roman Pontiff in governing the universal Church. This collaboration takes place both at the collegiate level in consistories and individually within the Roman Curia. The Apostolic ConstitutionPastor Bonus promulgated in 1988 by St. John Paul II devotes ample space to the service offered by the Cardinals in the departments. The author of this article will attempt to analyze the tasks entrusted to the Cardinals in the various Dicasteri, in particular at Congregations and the Secretariat of State, and pointing out the differences with the previous discipline of Regimini Ecclesiae Universae. Special attention will be devoted to the activity of coordination curial left to the Meeting of Cardinals and finally the relationship and discipline posed by Pastor Bonus to the relationship between the Roman Curia and the Consistories

    Dissipation of terbuthylazine, metolachlor, and mesotrione in soils with contrasting texture

    This study evaluates the dissipation of terbuthylazine, metolachlor, and mesotrione at different depths in soils with contrasting texture. The field trial was conducted at the Padua University Experimental Farm, north-east Italy. The persistence of three herbicides was studied in three different soil textures (clay soil, sandy soil, and loamy soil) at two depths (0–5 and 5–15 cm). Soil organic carbon content was highest in the clay (1.10%) followed by loam (0.67%) and sandy soil (0.24%); the pH of soils was sub-alkaline. Terbuthylazine, metolachlor, and mesotrione were applied on maize as a formulated product (Lumax®) at a dose of 3.5 L ha−1. Their dissipation in the treated plots was followed for 2 months after application. The concentrations of herbicides were analyzed by liquid chromatography-mass spectrometry. The dissipation of terbuthylazine, metolachlor, and mesotrione could be described by a pseudo first-order kinetics. Terbuthylazine showed the highest DT50, followed by metolachlor and mesotrione. Considering the tested soil, the highest DT50 value was found in clay soil for terbuthylazine and metolachlor, whereas for mesotrione there was no difference among soils. Significant differences were found between the two soil depths for terbuthylazine and metolachlor, whereas none were found for mesotrione. These results suggest that soil texture and depth have a strong influence on the dissipation of terbuthylazine and metolachlor, whereas no influence was observed on mesotrione because of its chemical and physical properties

    Decyl glucoside surfactant Triton CG-110 does not significantly affect the environmental fate of glyphosate in the soil at environmentally relevant concentrations

    Glyphosate is the most common herbicide worldwide, and its impact on the environment has increasingly been scrutinized. Glyphosate-based formulations can contain co-formulants, among which are surfactants. This study aimed to investigate whether the presence of an alkyl polyglucoside-based surfactant, Triton CG-110, affects the adsorption, leaching, and mineralisation of glyphosate in the soil. The experiments were conducted in two soils with different textures (sandy and clay) and in washed sand. Glyphosate and surfactant mixtures were applied at realistic field rates. Because of ponding and scarce leaching from the field soil, the leaching experiments were conducted only with washed sand. The results indicate a reduction of glyphosate adsorption in washed sand (from Kf = 13.5 to 3.99 μg1−1/n (ml)1/n g−1) and in sandy soil (from Kf = 165 to 90.8 μg1−1/ n (ml)1/n g−1) when using a Triton CG-110 concentration of 0.5 %, which corresponds to that of a spraying solution applied in the field, whereas adsorption in clay soil was unaffected. Triton CG-110 did not significantly affect glyphosate leaching in washed sand or mineralisation in any of the tested soils. The results indicate that Triton CG-110 is unlikely to significantly affect the environmental fate of glyphosate in the soil at environmentally relevant concentrations

    The Mixed WKB-Full-Wave Approach and its Application to Lower Hybrid Wave Propagation and Absorption

    No full text
    The mixed WKB-full-wave approach for calculating the 2D mode structure in tokamak plasmas is further developed based on our previous work [A. Cardinali et al., Phys. Plasmas 10, 4199 (2003) and Z. X. Lu et al., Phys. Plasmas, 19, 042104 (2012)]. A new scheme for theoretical analysis and numerical implementation of the mixed WKB-full-wave approach is formulated, based on scale separation and asymptotic analysis, to investigate lower hybrid wave (LHW) propagation and absorption. As a novel method, its comparison with other approaches is discussed. Its application to LHW propagation in concentric circular tokamak plasmas using typical FTU discharge parameters, is also demonstrated.Physics, AppliedPhysics, Fluids & PlasmasEICPCI-S(ISTP)

    The mixed Wentzel-Kramers-Brillouin (WKB)-full-wave approach for the calculation of the 2D mode structure in tokamak plasmas is further developed based on our previous work [A. Cardinali and F. Zonca, Phys. Plasmas 10, 4199 (2003) and Z. X. Lu et al., Phys. Plasmas 19, 042104 (2012)]. A new scheme for theoretical analysis and numerical implementation of the mixed WKB-full-wave approach is formulated, based on scale separation and asymptotic analysis. Besides its capability to efficiently investigate the initial value problem for 2D mode structures and linear stability, in this work, the mixed WKB-full-wave approach is extended to the investigation of radio frequency wave propagation and absorption, e. g., lower hybrid waves. As a novel method, its comparison with other approaches, e.g., WKB and beam tracing methods, is discussed. Its application to lower hybrid wave propagation in concentric circular tokamak plasmas using typical FTU discharge parameters is also demonstrated. (C) 2013 American Institute of Physics.
