The monitoring of the effects of geohazards on pipelines can be addressed by optical fiber Bragg gratings (FBGs). They are sensitive to strain and bending, and are installed on the external surface ...of pipelines at discrete locations. A joint approach of theoretical analysis and laboratory experiments is useful to check the reliability of the performance of this technology. We focus on the theoretical analysis of pipeline buckling and investigate the reliability of FBG monitoring both by examining the analytical model available and by performing a laboratory-scale experiment. The novelty lies in the analysis of models and methods originally developed for the detection of pipeline upheaval buckling caused by externally imposed forces in the context of service loads (temperature). Although thermal strain is very relevant in view of its potentially disruptive effects on both pipelines and the FBG response, it has not been yet fully investigated. We point out the merits of the approach, such as the functionality and simplicity of design, the accessibility and inexpensiveness of materials, the controllability and repeatability of processes, the drawbacks are also described, such as temperature effects, the problem of slipping of gages and the challenge of performing quasi-distributed strain measurements.
La statue de Giordano Bruno dressée sur le Campo de Fiori, le procès de Galilée dont la mémoire est toujours présente à travers le théâtre ou les débats de l’Académie pontificale des sciences disent ...assez combien le destin de la Rome des XVIIe et XVIIIe siècles a été négativement associé à celui de la science moderne et de son avènement conflictuel. Les études réunies dans ce volume, résultat d’un programme collectif de recherche sur la genèse de la culture scientifique européenne, entendent apporter une nouvelle contribution non seulement au dossier de la révolution scientifique en milieu catholique, mais plus largement à celui des relations que chaque société entretient avec les acteurs et la production du savoir et de la science. La focale mise sur Rome, comme milieu social spécifique, comme capitale de la catholicité et comme centre d’une monarchie pontificale en profond renouvellement entre XVIe et XVIIIe siècle, permet de discuter les paradigmes classiques d’une historiographie qui a trop hâtivement relégué le milieu romain à la marge de toute forme d’innovation savante. Il s’agit aussi d’ouvrir de nouvelles pistes de réflexions et de nouveaux chantiers sur les diverses configurations socio-intellectuelles au sein desquelles le travail savant a continué à faire de Rome un centre actif de travail et de production de savoirs.
Carlino examines the intertextual relationship between Petrarch's Invective contra medicum and some foundational texts of the skeptical tradition in medicine, such as Agrippa's De incertitudine et ...vanitate scientiarium and Montaigne's De la resemblance des enfans aux peres.
The essay II, 37 De la ressemblance des enfants aux pères, written by Montaigne between 1579 and the first months of 1580, is a merciless critique of doctors, doctoring and medicine in general. This ...Essay, as much as a large number of other texts, of archival records, of iconographic materials produced during the Early Modern period, testifies a wide spread skeptical attitude toward medicine across Europe. This is an important aspect of Early Modern culture. Despite its relevance it has been often neglected by medical historians. This paper aims to show how a literary text can contribute to the understanding of the rise of some aspects of these critical attitudes towards medicine and medics. In Montaigne's text, these attitudes appear to be generated by his personal experiences of suffering and disillusion deeply entangled with a long tradition of philosophical skepticism to which some of his favorite readings belong. Both these elements seem to have also contributed to bring Montaigne in 1580 to the definition of the poetic project of the Essays as a self-portrait: a project in which the bodily presence of the author, with his humors, passions and sufferings, is self-consciously part of the writing process and of the intellectual enterprise.
«Libri » e «persone » costituiscono due degli assi tematici che hanno guidato la riflessione del gruppo di studio sulla scienza a Roma in età moderna. Questo saggio scaturisce da questa riflessione ...collettiva e si propone, attraverso l’analisi della vicenda editoriale di un solo libro cinquecentesco, l’Anatomia di Juan de Valverde, tre obiettivi. Il primo è quello di comprendere il ruolo giocato da diversi tipi di relazioni personali (solidarietà nazionali, affinità intellettuali, interessi commerciali, rapporti terapeutici) nella realizzazione di un libro, nel caso specifico, scientifico. Il secondo obiettivo – conseguenza del precedente – è di proporre l’assunto che la realizzazione di un libro in questo periodo è il frutto delle molteplici attività di un collettivo autoriale
(in contrapposizione all’identificazione di un testo con un singolo autore) che comprende oltre allo scrittore, il tipografo, il committente, il disegnatore, l’incisore, etc. Il terzo obiettivo è quello di fornire ulteriori spunti per una concezione integrata della «materia scientifica » e della «materia umanistica » nel Cinquecento, mettendo in rilievo, ad esempio, i rapporti tra anatomia e antiquaria nel libro di Valverde.
