The raw ham’s ripening process contributes to the development of numerous biochemical reactions, mainly affecting proteins and lipids and allowing to obtain an adequate texture and a characteristic flavor. This article reports the results of histologic investigations carried out on 5 different anatomic regions from raw hams manufactured in the Fermo Province, Marche Region, Central Italy. Raw ham specimens were collected at the 10 following time intervals throughout the ripening process: 1) “Time 0”, when ripening was started, 2) one month, 3) three months, 4) four months, 5) eight months, 6) nine months, 7) twelve months, 8) eighteen months, 9) twentythree months and 10) twenty-eight months after the ripening process began, respectively. Different microscopic findings of variable extension and degree were observed, with the vast majority of them being interpreted as dehydration- and proteolysisrelated modifications. In conclusion, morpho- histological investigations may represent a valuable aid in raw ham’s ripening analysis.

The presence of the Eurasian beaver Castor fiber L. has been recently confirmed with two separated populations in Tuscany (Central Italy) and probably represents the result of an unofficial release. In late spring and summer 2021, seven reliable records of Eurasian beaver have been collected in Umbria and other neighbouring regions, implying that the distribution of this large rodent is even wider than previously reported. In this short work, we updated the distribution of this protected species in Central Italy, by collecting and mapping all the confirmed occurrences. Beavers were proved to be present throughout the Tiber (Tevere) river basin in both provinces of Umbria, and another individual has been road-killed in the Marche region, near the border with Tuscany. Other single signs of presence occurred in Emilia Romagna and Latium. The only hair sample we were able to collect confirmed it as the Eurasian beaver species. No reliable evidence is available on the number of free-ranging beavers in Central Italy, and systematic monitoring is needed. Before any management and conservation action, further data are required concerning distribution range, potential origin, social perception, and the effects on the ecosystems.

In the Marche Region (Central Italy), the residual municipal waste (RMW) is commonly processed in mechanical biological treatment (MBT) systems. In these systems, following a first mechanical selection, the undersize organic fraction from RMW (us-OFRMW) undergoes a partial aerobic biological treatment before being landfilled as a biostabilised fraction (bios-OFRMW) without dedicated energy or material recovery. Alternative us-OFRMW management scenarios have been elaborated for this region, at both present (reference year 2019) and future (reference year 2035) time bases. In the first scenario, the potential bioenergy recovery through anaerobic digestion (AD) from the us-OFRMW was evaluated. The second scenario aimed at evaluating the residual methane generation expected from the bios-OFRMW once landfilled, thus contributing also to the potential environmental impact connected with landfill gas (LFG) diffuse emissions from the regional landfills. The diversion to AD, at the present time, would allow a potential bioenergy recovery from the us-OFRMW equal to 4.35 MWel, while the alternative scenario involves greenhouse gas (GHG) emissions equal to 195 kg CO2 eq. per ton of deposited bios-OFRMW. In the future, the decreased amount of the us-OFRMW addressed to AD would still contribute with a potential bioenergy recovery of 3.47 MWel.

Abstract. We present a method to educate the public about landscapes that uses artistic works to broaden the audience, entice people to learn about landscapes in a personal and human context, and thus encourage them to preserve the natural heritage. To this end, we use narratives about a place, in plain language, accompanied by visual presentations, original poetry, and ancient music. Several studies encourage the use of art since it can help to synthesize and convey complex scientific information and create a celebratory and positive atmosphere. Evidence suggests that the arts can deeply engage people by focusing on emotions rather than relying only on comprehension, which is often emphasized in science communication. The multidisciplinary approach arouses an emotional and intellectual experience that enables a personal connection to the place. The work is part of a larger multidisciplinary project covering 20 sites in the Marche region (central Italy), which includes scientific information on geological–geomorphological genesis, trekking itineraries, poetry, ancient music, video, and cultural offerings. The project resulted in live multidisciplinary performances, a book, a DVD, and a website. To give a taste of how we work among the many amazing landscapes of the Marche region, we focus here on three sites from the north, the centre, and the south of the region, namely the sea cliff of San Bartolo, the flatiron of Mount Petrano, and the fault of Mount Vettore, chosen as examples for their different processes of genesis and evolution. In the long run, our goal is to promote a deeper understanding of landscapes by integrating their origin and physical aesthetic with their cultural and artistic heritage. In doing so, we intend to inspire people to have a new perception of geosites, starting from their physical beauty, building on scientific study and cultural history, and arriving at the knowledge of their social importance. So far, our direct experience with the public has been highly encouraging. The participation at our live shows demonstrated a great interest in geological history, a result that is relevant for the development of geotourism. The method demonstrates the potential to develop a strong personal involvement of visitors with the places, stimulating their curiosity to know how and why that place was formed, and, finally, the desire to visit and protect it.

Italy is a high seismic risk country since 1900 more than 30 earthquakes with magnitude greater than Mw=5.8 have occurred, and the last one is the Central Italy seismic sequence. The first shock occurred in the 24 August (Mw=6.2) followed by another stronger quake in the 30th October (Mw=6.5). It hit the regions of Marche, Umbria, and Abruzzo heavily causing many deaths, injuries and extensive damages on the cultural heritage. This paper analyses the church of San Francesco in Amadola, located in the Marche region that has been considered condemned for the severe damages reported after these earthquakes. The church is globally analyzed by the application of nonlinear static analysis on a Finite Element Model where the nonlinearity of masonry is taking into account with a proper constitutive law. The study wants to prove how global analysis combined by the local analysis can reproduce the behavior of this structure during a quake, showing that it can repeat the real damages produced by earthquakes.

Abstract. We investigated by means of nonlinear tools the temporal distribution of 1983-2003 seismicity of the Umbria-Marche region, Central Italy, that was struck by a strong event (M=5.8) on 26 September 1997. Information entropy analysis has been performed over the full and the aftershock-depleted catalogue. We analysed the series of the interevent times between successive earthquakes and the series of their magnitudes. The time evolution of this measure shows a clear anomalous behaviour in correspondence with the stronger event, more evident in the full catalogue than in the aftershock-depleted one.

Purpose The considerable volume of rubble generated by the 2016–2017 earthquakes in central Italy reveals a significant issue in the post-disaster reconstruction phase. Drawing from the experience of Macerata province and the city of Camerino, the purpose of this paper is to explore a possible change of attitude in the reuse of heritage waste materials in the reconstruction process of damaged historical villages and towns in Italy. Design/methodology/approach This research outlines a comparison between national and regional directives on the rubble management on the one hand, and the praxis on the other, carrying out semi-structured interviews with experts who have been involved in the reconstruction process of Macerata province and Camerino, in Marche region. Findings The research reveals that the current vision in Italy for the management of disaster waste is still very close to the traditional paradigm that gives heritage waste an intrinsic value, worthy of great efforts for its collection, catalogue and preservation in view of the likely philological restoration of the damaged heritage. The most recent experiences in Camerino show that institutions responsible for the conservation of cultural heritage may accept a possible paradigm shift towards a more innovative and less expert-driven approach to heritage waste materials and their possible upcycling. Originality/value Within a critique of the traditional restoration paradigm, this article links disaster waste management to the Sendai Framework for Disaster Risk Reduction, to enhance the long-term sustainability of historical villages and towns in Italy.
