Medico-legal considerations on "lotus Birth" in the Italian legislative framework
The term "Lotus Birth" identifies the practice of not cutting the umbilical cord and of leaving the placenta attached to the newborn after its expulsion until it detaches spontaneously, which generally occurs 3-10 days after birth. The first reported cases of Lotus Birth date back to 2004 in Australia. Supporters of such a procedure claim that the newborn is better perfused, endowed with a more robust immune system and "less stressed". However, it should be pointed out that histopathological study of the placenta is increasingly being requested in order to investigate problems of an infective nature or dysmaturity affecting the foetus, and situations of risk affecting the mother. Moreover, from the legal standpoint, there is no uniform position on the question of whether the placenta belongs to the mother or to the newborn. Lastly, a proper conservation of the embryonic adnexa is very difficult and includes problems of a hygiene/health, infectivological and medico-legal nature. The authors analyzed all these aspect in the Italian legislative framework, reaching the conclusion that Lotus Birth is inadvisable from both the scientific and logical/rational points of view
Exploring preferences for contractual terms in a scenario of ecological transition for the agri-food sector: a latent class approach
Governance mechanisms along the agri-food supply chains are increasingly important in a scenario of ecological transition. Under the conceptual and analytical lens of the Neo Institutional Economics, we explored farmers’ preferences towards a variety of clauses usually adopted in production contracts. To this purpose, a discrete choice experiment among 190 durum wheat producers in Italy was conducted. Results from a latent class model showed that that producers were mainly interested in fixed prices formula and to join shared rules of production but revealed little or no interest for compelling sustainable cultivation techniques and the provision of technical assistance. However, these preferences are heterogenous across farmers and vary depending on their level of education and previous use of contractual arrangements, with relevant implications for contract design and management

A 1/24 degree resolution Mediterranean analysis and forecast modeling system for the Copernicus Marine Environment Monitoring Service
The Mediterranean Forecasting System (MFS) is a numerical ocean prediction system that operationally
produces analyses, reanalyses and short-term forecasts of the main physical parameters for the entire
Mediterranean Sea and its Atlantic Ocean adjacent areas. This work is specifically focused on the
description and evaluation of the analysis and forecast modeling system that covers the analysis of the
current situation and produces daily updates of the following 10 days forecast. The system has been
recently upgraded in the framework of the Copernicus Marine Environment Monitoring Service
(CMEMS) by increasing the grid resolution from 1/16o to 1/24o in the horizontal and from 72 to 141
vertical levels, by increasing the number of fresh water river inputs and by updating the data assimilation
scheme. The model has a non-linear explicit free surface and it is forced by surface pressure, interactive
heat, momentum and water fluxes at the air-sea interface. In order to validate the modeling system and to
estimate the accuracy of the model products, a quality assessment is regularly performed including both
pre-operational qualification and near real time (NRT) validation procedures. Pre-operational
qualification activities focus on testing the improvements of the quality of the new system with respect
to the previous version and relies on past simulation and historical data, while NRT validation activities
aim at routinely and on-line providing the skill assessment of the model analysis and forecasts and relies
on the NRT available observations. The focus of this work is to present the new operational modeling
system and the skill assessment including comparison with independent (insitu coastal moorings) and
quasi-independent (insitu vertical profiles and satellite) datasets.PublishedBergen, Norway3SR. AMBIENTE - Servizi e ricerca per la Societ
A 1/24° resolution Mediterranean physical analysis and forecasting system for the Copernicus Marine Environment Monitoring Service
This study describes a new model implementation for the Mediterranean Sea that has
been achieved in the framework of the Copernicus Marine Environment Monitoring
Service (CMEMS). The numerical ocean prediction system, that operationally produces
analyses and forecasts of the main physical parameters for the entire Mediterranean
Sea and its Atlantic Ocean adjacent areas, has been upgraded by increasing the grid
resolution from 1/16o to 1/24o in the horizontal and from 72 to 141 unevenly spaced
vertical levels, by increasing the number of fresh water river inputs and by updating
the data assimilation scheme. The model has a non-linear explicit free surface and it
is forced by surface pressure, interactive heat, momentum and water fluxes at the airsea
interface. The focus of this work is to present the new modelling system which
will become operational in the near future and the validation assessment including
the comparison with an independent non assimilated dataset (coastal moorings) and
quasi-independent (in situ vertical profiles and satellite) datasets. The results show
that the higher resolution model is capable of representing most of the variability
of the general circulation in the Mediterranean Sea, however some improvements
need to be implemented in order to enhance the model ability in reproducing specific
hydrodynamic features particularly the Sea Level Anomaly.PublishedBergen, Norway3SR. AMBIENTE - Servizi e ricerca per la Societ
Mediterranean monitoring and forecasting operational system for Copernicus Marine Service
The MEDiterranean Monitoring and Forecasting Center (Med-MFC) is part of the Copernicus Marine Environment Monitoring Service (CMEMS, http://marine.copernicus.eu/), provided on an operational mode by Mercator Ocean in agreement with the European Commission.
Specifically, Med MFC system provides regular and systematic information about the physical state of the ocean and marine ecosystems for the Mediterranean Sea. The Med-MFC service started in May 2015 from the
pre-operational system developed during the MyOcean projects, consolidating the understanding of regional
Mediterranean Sea dynamics, from currents to biogeochemistry to waves, interfacing with local data collection
networks and guaranteeing an efficient link with other Centers in Copernicus network.
The Med-MFC products include analyses, 10 days forecasts and reanalysis, describing currents, temperature,
salinity, sea level and pelagic biogeochemistry. Waves products will be available in MED-MFC version in
2017. The consortium, composed of INGV (Italy), HCMR (Greece) and OGS (Italy) and coordinated by the
Euro-Mediterranean Centre on Climate Change (CMCC, Italy), performs advanced R&D activities and manages
the service delivery.
The Med-MFC infrastructure consists of 3 Production Units (PU), for Physics, Biogechemistry and Waves, a
unique Dissemination Unit (DU) and Archiving Unit (AU) and Backup Units (BU) for all principal components,
guaranteeing a resilient configuration of the service and providing and efficient and robust solution for the maintenance of the service and delivery. The Med-MFC includes also an evolution plan, both in terms of research and operational activities, oriented to increase the spatial resolution of products, to start wave products dissemination, to increase temporal extent of the reanalysis products and improving ocean physical modeling for delivering new products.
The scientific activities carried out in 2015 concerned some improvements in the physical, biogeochemical
and wave components of the system. Regarding the currents, new grid-point EOFs have been implemented in
the Med-MFC assimilation system; the climatological CMAP precipitation was replaced by the ECMWF daily
precipitation; reanalysis time-series have been increased by one year.
Regarding the biogeochemistry, the main scientific achievement is related to the implementation of the carbon
system in the Med-MFC biogeochemistry model system already available. The new model is able to reproduce the principal spatial patterns of the carbonate system variables in the Mediterranean Sea. Further, a key result consists of the calibration of the new variables (DIC and alkalinity), which serves to the estimation of the accuracy of the new products to be released in the next version of the system (i.e. pH and pCO2 at surface).
Regarding the waves, the system has been validated against in-situ and satellite observations. For example, a very good agreement between model output and in-situ observations has been obtained at offshore and/or well-exposed wave buoys in the Mediterranean Sea.PublishedVienna3SR.

SeaConditions: a web and mobile service for safer professional and recreational activities in the Mediterranean Sea
Abstract. Reliable and timely information on the environmental conditions at sea is key to the safety of professional and recreational users as well as to the optimal execution of their activities. The possibility of users obtaining environmental information in due time and with adequate accuracy in the marine and coastal environment is defined as sea situational awareness (SSA). Without adequate information on the environmental meteorological and oceanographic conditions, users have a limited capacity to respond, which has led to loss of lives and to large environmental disasters with enormous consequent damage to the economy, society and ecosystems. Within the framework of the TESSA project, new SSA services for the Mediterranean Sea have been developed. In this paper we present SeaConditions, which is a web and mobile application for the provision of meteorological and oceanographic observation and forecasting products. Model forecasts and satellite products from operational services, such as ECMWF and CMEMS, can be visualized in SeaConditions. In addition, layers of information related to bathymetry, sea level and ocean-colour data (chl a and water transparency) are displayed. Ocean forecasts at high spatial resolutions are included in the version of SeaConditions presented here. SeaConditions provides a user-friendly experience with a fluid zoom capability, facilitating the appropriate display of data with different levels of detail. SeaConditions is a single point of access to interactive maps from different geophysical fields, providing high-quality information based on advanced oceanographic models. The SeaConditions services are available through both web and mobile applications. The web application is available at www.sea-conditions.com and is accessible and compatible with present-day browsers. Interoperability with GIS software is implemented. User feedback has been collected and taken into account in order to improve the service. The SeaConditions iOS and Android apps have been downloaded by more than 105 000 users to date (May 2016), and more than 100 000 users have visited the web version
A single saddle model for the beta-relaxation in supercooled liquids
We study the Langevin equation for a single harmonic saddle as an elementary
model for the beta-relaxation in supercooled liquids close to Tc. The input of
the theory is the spectrum of the eigenvalues of the dominant stationary points
at a given temperature. We prove in general the existence of a time-scale
t_eps, which is uniquely determined by the spectrum, but is not simply related
to the fraction of negative eigenvalues. The mean square displacement develops
a plateau of length t_eps, such that a two-step relaxation is obtained if t_eps
diverges at Tc. We analyze the specific case of a spectrum with bounded left
tail, and show that in this case the mean square displacement has a scaling
dependence on time identical to the beta-relaxation regime of Mode Coupling
Theory, with power law approach to the plateau and power law divergence of
t_eps at Tc.Comment: Revised versio
Hybrid MPGD-based detectors of single photons for the upgrade of COMPASS RICH-1
A seven year-long R&D programme has been performed and the resulting detector architecture is a hybrid MPGD including two THick GEM (THGEM) multiplication stages followed a MICROMEGAS. The first THGEM board forms the photocathode support: its upper face is CsI coated. The properties of THGEM-based photocathodes have been studied in details. The two THGEM layers act as pre-amplification stages and, thanks to a staggered configuration, namely by the misalignment of the holes of the two THGEMs, the electron shower produced in the pre-amplification phase is distributed onto a larger surface portion of the following MICROMEGAS unit, where the final multiplication takes place: it is so possible to operate at gains as high as 105 and more even in radioactive environments. COMPASS RICH-1 is a large-size Cherenkov imaging counter with gaseous radiator for hadron identification up to 50 GeV/c. The construction of a set of large-size (unit size: 60
760 cm2) gaseous photon detectors based on the hybrid MPGD architecture for the upgrade of COMPASS RICH-1 is ongoing and the upgraded detector will be in operation in 2016. The R&D studies, the engineering aspects and the construction challenges are presented
