Navigating through archives, libraries and museums: Topic Maps as a harmonizing instrument

The paper deals with the possibility of creating a topic map based system where different sectors of cultural heritage would interact with users, by monitoring the navigation histories of users and the statistics on the searches, in order to authorize variant form of names. The problem of managing different sectors and harmonizing them both from a structural and a semantic view point, by using Topic Maps, is also discussed. With regards to this, we are introducing two projects, which are largely based on the above mention use of Topic Maps.

From typewriter to bit: how finding aids evolve

If the only tool you have is a hammer, you tend to treat everything as if it were a nail. But is it really so? Some thoughts on what determined the evolution of the finding aids, of the publication of archival databases on the web and of archival information systems. In this article we will analyze several of the solutions adopted during the time, trying to understand if these actually respond to the needs of the users of the archives

Descrizioni archivistiche e web semantico: un connubio possibile?

The article presents a reflection on the possibility to insert and manage archival description within the semantic web. The chosen language for this attempt is the one of Topic Maps, standard ISO 13250, a web semantic technology collateral to RDF. Through using TMCL (Topic Maps Constraint Language), the main construction will be presented, highlighting the scalability and flexibility options offered. The data model of Topic Maps defines some elements (constructions in the vocabulary) that, if combined, allow to express and codify a illimited range of descriptions and relations; moreover, they allows to manage multiple indexes disambiguating different terms. This contributions examines carefully agreements and possibilities of a mapping between topic maps and the main archival descriptive standards, presenting and example using ISAAR(CPF). The data in a description like this should integrate with the choosen language, showing practical advantages in extra supply tools, in exchanging data with other archivistic informative systems, and in in building flexible interface

Ideological polarization, policy continuity: back to the majoritarian principle?

This introduction to the Italian Politics 2023 special issue gives an overview of the main events characterizing Italian politics during a year of large-scale policy reforms, presidential and parliamentary elections, and the unexpected Russian invasion of Ukraine. The authors pose three questions concerning Italian politics during the year gone by. First, from an institutional viewpoint, they ask whether the revival of majoritarianism as a principle of government formation represents the prelude to a return to enduring party-system bipolarity. Second, from an electoral and public policy perspective, they ask whether the formation of a government led by what many perceive as a radical right party betokens the start of a correspondingly radical shift in Italian public policy. Third, from an international relations perspective, they ask about the extent to which the Meloni government’s attitude to the Russian invasion of Ukraine, and more generally to Italy’s position on the world stage and in international affairs, is likely to differ from that adopted by Draghi. The chapter elaborates on the three questions by tracing how the events of 2022 generated much more continuity than expected

Sleep and Chronobiology as a Key to Understand Cluster Headache

: The cluster headache is a primary headache characterized by attacks of unilateral pain associated with ipsilateral cranial autonomic features. These attacks recur in clusters during the years alternating with periods of complete remission, and their onset is often during the night. This annual and nocturnal periodicity hides a strong and mysterious link among CH, sleep, chronobiology and circadian rhythm. Behind this relationship, there may be the influence of genetic components or of anatomical structures such as the hypothalamus, which are both involved in regulating the biological clock and contributing even to the periodicity of cluster headaches. The bidirectional relationship manifests itself also with the presence of sleep disturbances in patients affected by cluster headaches. What if the key to studying the physiopathology of such disease could rely on the mechanisms of chronobiology? The purpose of this review is to analyze this link in order to interpret the pathophysiology of cluster headaches and the possible therapeutic implications

Erenumab and Possible CGRP Effect on Chronotype in Chronic Migraine: A Real-Life Study of 12 Months Treatment

: The introduction of monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP), or its receptor (CGRPr), revolutionized migraine management due to their high efficacy and few side effects. Data suggest that the CGRP may even be implicated in circadian rhythm, but studies about the effect of anti-CGRP treatments on sleep are still lacking. The aim of the present study was to assess the effect of erenumab (70 and 140 mg per month), a human mAb directed against CGRPr, on chronotype in chronic migraineurs; secondly, we assessed its efficacy, safety, and the effects on anxiety and depression. Sleep was evaluated using self-administrable questionnaires investigating chronotype, sleep quality, and daytime sleepiness. Migraine diaries and several self-administrable questionnaires regarding headache impact and psychological correlates were evaluated every 3 months during 12 months of treatment. Eighty-eight patients were included; most of them showed a significant reduction in headache frequency and an improvement in psychological symptoms. Moreover, an initial change in chronotype was observed at the three-month assessment from a morning chronotype to an intermediate one; a similar trend remained in the other evaluations, even if it did not reach a statistical significance. Lastly, patients who responded to the treatment showed a progressive sleep efficiency reduction. The present real-life study hypothesized the influence of erenumab on chronotype, representing a link between circadian rhythm, CGRP, and migraine

Synergetic Application of Zero-, One-, and Three-Dimensional Computational Fluid Dynamics Approaches for Hydrogen-Fuelled Spark Ignition Engine Simulation

Nowadays hydrogen, especially if derived from biomass or produced by renewable power, is rising as a key energy solution to shift the mobility of the future toward a low-emission scenario. It is well known that hydrogen can be used with both internal combustion engines (ICEs) and fuel cells (FCs); however, hydrogen-fuelled ICE represents a robust and cost-efficient option to be quickly implemented under the current production infrastructure. In this framework, this article focuses on the conversion of a state-of-the-art 3.0L diesel engine in a hydrogen-fuelled Spark Ignition (SI) one. To preliminarily evaluate the potential of the converted ICE, a proper simulation methodology was defined combining zero-, one-, and three-dimensional (0D/1D/3D) Computational Fluid Dynamics (CFD) approaches. First of all, a detailed kinetic scheme was selected for both hydrogen combustion and Nitrogen Oxides (NOx) emission predictions in a 3D-CFD environment. Afterward, to bring the analysis to a system-level approach, a 1D-CFD predictive combustion model was firstly optimized by implementing a specific laminar flame speed correlation and, secondly, calibrated against the 3D-CFD combustion results. The combustion model was then integrated into a complete engine model to assess the potential benefit derived from the wide range of flammability and the high flame speed of hydrogen on a complete engine map, considering NOx formation and knock avoidance as priority parameters to control. Without a specific modification of turbocharger and combustion systems, a power density of 34 kW/L and a maximum brake thermal efficiency (BTE) of about 42% were achieved, thus paving the way for further hardware optimization (e.g., compression ratio reduction, turbocharger optimization, direct injection [DI]) to fully exploit the advantages enabled by hydrogen combustion
