    L'urgenza di dire "altro" e una "lunga fedeltĂ ": appunti per una storia della poesia sannazariana

    Get PDF
    The essay is an attempt to organize in a system some meta-poetic passages of Sannazaro's poetry (author's declarations) and to lead the utterances back to a unique thought and to an equally unique and exclusive basic choice. In these pages, a selected (and therefore reduced) number of lines from Arcadia, from Sonetti et Canzoni, from Elegie, from Piscatorie and from De partu Virginis are read and interpreted in the light of what we can consider, on the part of Iacopo Sannazaro, a "long fidelity": fidelity to the universe of bucolic poetry, acted out over almost half a century through the practice of different genres, from bucolic to lyric, from elegiac poetry to sacred epic.   Il saggio Ăš un tentativo di organizzare in sistema alcuni passaggi meta-poetici della poesia sannazariana (dichiarazioni d’autore) e di ricondurne gli enunciati a un pensiero unico e a un’altrettanto unica ed esclusiva scelta di fondo. In queste pagine un numero selezionato (quindi ridotto) di versi dell’Arcadia, di versi di Sonetti et Canzoni, di versi delle Elegie, di versi delle Piscatorie e di versi del De partu Virginis viene letto e interpretato alla luce di quella che possiamo considerare, da parte di Iacopo Sannazaro una “lunga fedeltà”: fedeltĂ  all’universo della poesia bucolica, agita nell’arco di quasi mezzo secolo attraverso la pratica di generi diversi, dall’egloghistica alla lirica, dalla poesia elegiaca all’epica sacra

    Change and continuity at PPA

    This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.In June 2017, Public Policy and Administration (PPA) received its first Impact Factor of 1.529 in 2016 Journal Citation Reports¼. It is a fantastic score, even more so considering this has been the very first year the journal was included in the index. As a result, PPA is now ranked 19/47 in the field ‘Public Administration’! This is major change for PPA, which this year celebrates its 30th year, and bodes very well for its future. And so, we want to take this opportunity to send a strong message of continuity to our readership and all the prospective contributors. [...

    Application of an integrated geotechnical and topographic monitoring system in the Lorano marble quarry (Apuan Alps, Italy)

    PublishedThis is the author accepted manuscript. The final version is available from Elsevier via http://dx.doi.org/10.1016/j.geomorph.2015.04.009Accurate slope stability analysis is essential for human activity in high-risk geological contexts. This may, however, not be enough in the case of quarrying where the dynamic and evolving environment also requires effective monitoring. A well-designed monitoring system requires the acquisition of a huge dataset over time, improving knowledge of the study area and helping to refine prediction from stability analysis.This paper reports the implementation of an integrated monitoring system in a marble quarry in the Apuan Alps (Italy) and some of the results obtained. The equipment consists of a traditional geotechnical monitoring system (extensometers, crackmeters and clinometers) and two modern topographic monitoring systems (a terrestrial interferometer and a robotic total station). This work aims to provide in-depth knowledge of the large scale rock mass behaviour as a result of marble exploitation, thereby allowing continuous excavation. The results highlight the importance of integrating different monitoring systems.The present study was undertaken within the framework of the Italian National Research Project PRIN2009, funded by the Ministry of Education, Universities and Research, which involves the collaboration between the University of Siena, “La Sapienza” University of Rome, and USL1 of Massa and Carrara (Mining Engineering Operative Unit - Department of Prevention)

    JERRY: An Interactive Planning Tool for Space Robotics

    Get PDF
    JERRY is a modular system for the interactive design, planning, control and supervision of the operation of autonomous robot systems in space. In such a highly critical environment, JERRY can effectively support the robot operators in both ordinary and emergency situations and make their work easier, safer and faster. JERRY can also provide scientists with no specific competence in robotics with a higher-level support for the automated execution of complex robot activities, with limited contributions from specialized operators

    Geological 3D modeling for excavation activity in an underground marble quarry in the Apuan Alps (Italy)

    Get PDF
    The three-dimensional laser scanning technique has recently become common in diverse working environments. Even in geology, where further development is needed, this technique is increasingly useful in tackling various problems such as stability investigations or geological and geotechnical monitoring. Three-dimensional laser scanning supplies detailed and complete geometrical information in short working times, as a result of the acquisition of a large number of data-points that accurately model the detected surfaces. Moreover, it is possible to combine these data with high quality photographic images so as to provide important information for geological applications, as follows. A working approach, that combines terrestrial laser scanning and traditional geological surveys, is presented. A three-dimensional model, that includes information about the geological structure in an underground quarry in the Apuan Alps, is realized. This procedure is adaptable to other geological contexts, and because of its operating speed and accuracy it is invaluable for optimal excavation, in which a proper planning of quarrying activity is vital for safety and commercial reasons. © 2014 Elsevier Ltd.The authors gratefully acknowledge the assistance of the personnel of the Romana Quarry and particularly Geol. Massimo Corniani. This paper was possible because of support from the Tuscany Region Research Project known as “Health and safety in the quarries of ornamental stones – SECURCAVE”

    3D Printing of PDMS-Like Polymer Nanocomposites with Enhanced Thermal Conductivity: Boron Nitride Based Photocuring System

    Get PDF
    This study demonstrates the possibility of forming 3D structures with enhanced thermal conductivity (k) by vat printing a silicone–acrylate based nanocomposite. Polydimethylsiloxane (PDSM) represent a common silicone-based polymer used in several applications from electronics to microfluidics. Unfortunately, the k value of the polymer is low, so a composite is required to be formed in order to increase its thermal conductivity. Several types of fillers are available to reach this result. In this study, boron nitride (BN) nanoparticles were used to increase the thermal conductivity of a PDMS-like photocurable matrix. A digital light processing (DLP) system was employed to form complex structures. The viscosity of the formulation was firstly investigated; photorheology and attenuate total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) analyses were done to check the reactivity of the system that resulted as suitable for DLP printing. Mechanical and thermal analyses were performed on printed samples through dynamic mechanical thermal analysis (DMTA) and tensile tests, revealing a positive effect of the BN nanoparticles. Morphological characterization was performed by scanning electron microscopy (SEM). Finally, thermal analysis demonstrated that the thermal conductivity of the material was improved, maintaining the possibility of producing 3D printable formulations

    Magnetic-Oriented Nickel Particles and Nickel-Coated Carbon Nanotubes: An Efficient Tool for Enhancing Thermal Conductivity of PDMS Composites

    Get PDF
    In this study, PDMS composites are thermally cured with nickel particles and nickel-coated carbon nanotubes as fillers. Both fillers are oriented with the aim to increase the thermal conductivity of the silicone polymer network, due to the formation of a continuous thermal path. Scanning electron microscopy (SEM) gives a picture of the polymer network's morphology, proving the effective alignment of the nickel particles. Rheology and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) studies confirm the full curing of the silicon network and no influence in the curing kinetics of the type and content of fillers and their orientation. Dynamic mechanical thermal analysis (DMTA) and tensile analysis show instead different thermo-mechanical behavior of the polymer network due to the presence of different fillers, different fillers percentage, and orientation. Finally, the thermal transmittance coefficient (k) is studied by means of hot disk analysis, revealing the increment of almost 200% due to magnetic filler orientation
