Sea-Level Change along the Emilia-Romagna Coast from Tide Gauge and Satellite Altimetry
Coastal flooding and retreat are markedly enhanced by sea-level rise. Thus, it is crucial to determine the sea-level variation at the local scale in order to support coastal hazard assessment and related management policies. In this work we focus on sea-level change along the Emilia-Romagna coast, a highly urbanized, 130 km-long belt facing the Northern Adriatic Sea, by analysing data from three tide gauges (with data records in the last 25-10 years) and related closest grid points from ESA_CCI monthly gridded satellite altimetry. The results reveal that the rate of sea-level rise observed by altimetry is coherent along the coast (2.8 \ub1 0.5 mm/yr) for the period 1993-2019 and that a negative acceleration of -0.3 \ub1 0.1 mm/yr is present, in contrast with the global scale. Rates resulting from tide gauge time series analysis diverge from these values mainly in consequence of a large and heterogeneous rate of subsidence in the region. Over the common time span, altimetry and tide gauge data show very high correlation, although their comparison suffers from the short overlapping period between the two data sets. Nevertheless, their combined use allows to assess the recent (last 25 years) sea-level change along the Emilia-Romagna coast and to discuss the role of different interacting processes in the determination of the local sea level
Chapter Italiani brava gente? Sui rapporti cinematografici fra Italia e URSS
Numerous and rich materials in yet unpublished archives provide information on the coproduction of several Italian and Soviet films, the first of which is Giuseppe De Santis’s Attack and Retreat (1961-1964), representing almost four years’ of work. This article examines radically different versions of the script, the minutes of meetings in which these scripts were reviewed by both parties, and other documents relating to process of joint production to reveal a number of curious details. We also demonstrate that this was a far from peaceful process and that the tortuous progress made by the partners was symptomatic of political and cultural issues in their countries of origin
Medici, “Marleen” e militari. O della “Brava gente” al cinema
The subject of the article is the film Attack and Retreat, the first Italian-Soviet
film in co-production, signed by the director Giuseppe De Santis. In particular, I would like to point out the differences between the film and the original
script and the numerous scripts by Sergei Smirnov and De Santis himself, preserved both in Moscow and Rome. Corrections, cuts and compromises show
that writing a text that would bring Russians and Italians in agreement was
not easy; the diversity of views reflected the delicate economic, political and
cultural balances between the two countries at the time. The analisis of the
various scrips allows us to recognize their literary value and understand the
mechanisms with which ideology becomes literatur
Towards transnational interoperable PPDR communications: the European ISI cloud network
The European Council has been stressing the need for interoperability among technologies used for Public Protection and Disaster Relief (PPDR) communications across Europe for a long time. Nevertheless, while the introduction of TETRA and TETRAPOL technologies in the last two decades has increased the possibility to talk cross agency internally in a country, cross border communication for the public safety forces is not well solved as of today. This paper describes the communications interoperability solution that is being developed in the framework of the ISITEP project. This solution, referred to as the European Inter-System Interface (ISI) Cloud Network, aims to integrate the PPDR national/regional infrastructures to allow migration (i.e., roaming) and communication services between networks within a secure framework. The ISI Cloud Network involves, among other components, the specification of a new ISI interface to be deployed over IP transport networks and the development of a number of different gateways to cover the use of TETRA and TETRAPOL technologies as well as the use of legacy TETRA ISI by some networks.Peer ReviewedPostprint (author's final draft
Indole-3-acetic acid attenuates the fungal lesions in infected potato tubers
In this report, we demonstrated that potato tubers pre-treated with 100 ÎĽM of indole-3-acetic acid (IAA) and then inoculated with Fusarium solani f. sp. eumartii (F. eumartii) showed a decrease in the fungal lesion compared with non-IAA pre-treated and inoculated tubers. Consequently, we tested the addition of different concentrations of IAA on the fungal growth and on the proteolytic activity when the fungus was grown in liquid culture medium. Fungal growth did not change under different phytohormone concentrations, but the activity of Fusarium extracellular serine protease (FESP) clearly decreased. The inhibition of FESP activity by IAA was dose dependent. Moreover, FESP as well as others extracellular pectinolytic activities detected in IAA pre-treated and inoculated tubers decreased compared with controls. In addition, the ability of IAA production by F. eumartii was tested, and the role of IAA on potato-F. eumartii interaction is discussed.Fil: Terrile, Maria Cecilia.

Security in transnational interoperable PPDR communications: threats and requirements
The relevance of cross border security operations
has been identified as a priority at European level for a long time.
A European network where Public Protection and Disaster Relief
(PPDR) forces share communications processes and a legal
framework would greatly enforce response to disaster recovery
and security against crime. Nevertheless, uncertainty on costs,
timescale and functionalities have slowed down the
interconnection of PPDR networks across countries and limited
the transnational cooperation of their PPDR forces so far. In this
context, the European research project ISITEP is aimed at
developing the legal, operational and technical framework to
achieve a cost effective solution for PPDR interoperability across
European countries. Inter alia, ISITEP project is specifying a
new Inter-System-Interface (ISI) interface for the
interconnection of current TETRA and TETRAPOL networks
that can be deployed over Internet Protocol (IP) connectivity.
This approach turns communications security as a central aspect
to consider when deploying the new IP ISI protocol between
PPDR national networks. Ensuring that threats to the
interconnected communications systems and terminals are
sufficiently and appropriately reduced by technical, procedural
and environmental countermeasures is vital to realise the trusted
and secure communication system needed for the pursued PPDR
transnational cooperation activities. In this context, this paper
describes the framework and methodology defined to carry out
the development of the security requirements and provides a
discussion on the undertaken security risk and vulnerability
analysis.Peer ReviewedPostprint (author's final draft
In vivo confocal microscopy study of corneal nerve alterations in children and youths with Type 1 Diabetes
Objective: To determine whether children and youths with type 1 diabetes (T1D) have early alterations of the corneal subbasal nerve plexus detectable with In vivo confocal microscopy (IVCM) and to investigate the role of longitudinally measured major risk factors for diabetes complications associated with these alterations. Methods: One hundred and fifty children and youths with T1D and 51 age-matched controls were enrolled and underwent IVCM. Corneal nerve fiber length (CNFL), corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), corneal fiber total branch density (CTBD), and corneal fiber fractal dimension (CNFrD) were measured. Risk factors for diabetes complications (blood pressure, BMI, HbA1c, lipoproteins, urinary albumin-creatinine ratio) were recorded at IVCM and longitudinally since T1D onset. Unpaired t-test was used to compare variables between the groups. Multiple regression models were calculated using IVCM parameters as dependent variables and risk factors as independent variables. Results: All IVCM parameters, except CTBD, were significantly lower in the T1D patients. Glycometabolic control (HbA1c, visit-to-visit HbA1c variability, and mean HbA1c), and blood pressure were inversely correlated with IVCM parameters. Multiple regression showed that part of the variability in CNFL, CNFD, CTBD, and CNFraD was explained by HbA1c, blood pressure percentiles, and age at IVCM examination, independent of diabetes duration, BMI percentile, and LDL cholesterol. Comparable results were obtained using the mean value of risk factors measured longitudinally since T1D onset. Conclusions: Early signs of corneal nerve degeneration were found in children and youths with T1D. Glycometabolic control and blood pressure were the major risk factors for these alterations.

Detection of Testudinid alphaherpesvirus, Chlamydia spp., Mycoplasma spp., and Salmonella spp. in free‑ranging and rescued Italian Testudo hermanni hermanni.
Testudo hermanni is included as near‑threatened in the Red List of the International Union for Conservation of Nature, while T. hermanni hermanni is considered endangered in the Italian Red List. Appropriate management of smuggled or seized wild individuals is recommended before their reintroduction into the wild. Accordingly, a health monitoring study was carried out. During 2014‑2016, 133 oral swabs and 121 cloacal swabs were collected from a total of approximately 180 free‑ranging and rescued T. hermanni hermanni from eight different Italian regions to investigate the presence of DNA of Testudinid alphaherpesvirus (TeAHV), Chlamydia spp. and Mycoplasma spp. in the oral cavity, and Salmonella spp. isolates in the cloaca. Mycoplasma spp. was detected in 52 out of 87 (59.77%) of rescued and in 1 out of 46 free‑ranging (2.17%) individuals; 33 out of 53 (62.26%) Mycoplasma spp. positive samples were typed as M. agassizii by PCR. Salmonella spp. was isolated from 45 out of 121 (37.19%) cloacal swabs, typed into 14 serovars, and characterized for complete antimicrobial susceptibility. A significantly different distribution of Salmonella spp. isolates was found in 2016 in comparison with 2014 and 2015, without any difference between free‑ranging and rescued tortoises. All the tested tortoises were negative for TeAHV and Chlamydia spp. These results are considered a baseline information critical to monitor the dynamics of these microorganisms in free‑ranging and rescued populations of T. h. hermanni, and to correctly approach the management of rescued animals and possible relocation programs
