The Application of the Life-Cycle Assessment in the Building Sector: An Italian Case Study
2017
The building sector is one of the most relevant in terms of generation of wealth and occupation, but it is also responsible for significant consumption of natural resources and the generation of environmental impacts, mainly greenhouse gas emissions. In order to improve the eco profile of buildings during their life-cycle, the reduction of the use of resources and the minimization of environmental impacts have become, in the last years, some of the main objectives to achieve in the design of sustainable buildings. The application of the life-cycle thinking approach, looking at the whole life cycle of buildings, is of paramount importance for a real decarbonization and reduction of the envir…
STRATEGIE E CRITERI PROGETTUALI PER LA CONVERSIONE DI LINEE FERROVIARIE DISMESSE IN PERCORSI VERDI
2009
Il progressivo incremento della mobilità privata, verificatosi a partire dalla seconda metà del secolo scorso nei Paesi occidentali, e in particolare in Italia, ha determinato la chiusura al traffico di molte linee ferroviarie secondarie ormai scarsamente utilizzate e, dunque, poco remunerative per gli Enti proprietari e/o gestori. Il patrimonio viario dismesso trova oggi una possibile occasione di riqualificazione funzionale mediante la conversione delle linee ferrate in percorsi verdi (greenways) dedicati alla cosiddetta “mobilità dolce” di tipo ciclopedonale; ciò in ragione delle seguenti caratteristiche: i) separazione del sedime ferroviario dalla rete stradale ordinaria; ii) ridotto nu…
Many-body Green's function theory for electron-phonon interactions: ground state properties of the Holstein dimer
2015
We study ground-state properties of a two-site, two-electron Holstein model describing two molecules coupled indirectly via electron-phonon interaction by using both exact diagonalization and self-consistent diagrammatic many-body perturbation theory. The Hartree and self-consistent Born approximations used in the present work are studied at different levels of self-consistency. The governing equations are shown to exhibit multiple solutions when the electron-phonon interaction is sufficiently strong whereas at smaller interactions only a single solution is found. The additional solutions at larger electron-phonon couplings correspond to symmetry-broken states with inhomogeneous electron de…
Environmental mitigation hierarchy and biodiversity offsets revisited through habitat connectivity modelling.
2020
International audience; Biodiversity loss is accelerating because of unceasing human activity and land clearing for development projects (urbanisation, transport infrastructure, mining and quarrying …). Environmental policy-makers and managers in different countries worldwide have proposed the mitigation hierarchy to ensure the goal of “no net loss (NNL) of biodiversity” and have included this principle in environmental impact assessment processes. However, spatial configuration is hardly ever taken into account in the mitigation hierarchy even though it would greatly benefit from recent developments in habitat connectivity modelling incorporating landscape graphs. Meanwhile, national, Euro…

Coastal high-frequency radars in the Mediterranean - Part 2: Applications in support of science priorities and societal needs
2022
The Mediterranean Sea is a prominent climate-change hot spot, with many socioeconomically vital coastal areas being the most vulnerable targets for maritime safety, diverse met-ocean hazards and marine pollution. Providing an unprecedented spatial and temporal resolution at wide coastal areas, high-frequency radars (HFRs) have been steadily gaining recognition as an effective land-based remote sensing technology for continuous monitoring of the surface circulation, increasingly waves and occasionally winds. HFR measurements have boosted the thorough scientific knowledge of coastal processes, also fostering a broad range of applications, which has promoted their integration in coastal ocean …
Statistical upscaling of ecosystem CO2 fluxes across the terrestrial tundra and boreal domain: Regional patterns and uncertainties
2021
The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high, complicating efforts to quantify sink-source patterns across the entire region. Statistical models are increasingly used to predict (i.e., upscale) CO2 fluxes across large spatial domains, but the reliability of different modeling techniques, each with different specifications and assumptions, has not been assessed in detail. Here, we compile eddy covariance and chamber measurements of annual and growing season CO2 fluxes of gross primary productivity (GPP), ecosystem respiration (ER), and net ecosystem exchange (NEE) during 1990–2015 from 148 terrestrial high-latitude (i.e., tundra and boreal) sites to a…

Beyond Sentinel Lymph Node: Outcomes of Indocyanine Green-Guided Pelvic Lymphadenectomy in Endometrial and Cervical Cancer
2023
Background: The aim of our study was to compare the number of lymph nodes removed during indocyanine green (ICG)-guided laparoscopic/robotic pelvic lymphadenectomy with standard systematic lymphadenectomy in endometrial cancer (EC) and cervical cancer (CC). Methods: This is a multicenter retrospective comparative study (Clinical Trial ID: NCT04246580; updated on 31 January 2023). Women affected by EC and CC who underwent laparoscopic/robotic systematic pelvic lymphadenectomy, with (cases) or without (controls) the use of ICG tracer injection within the uterine cervix, were included in the study. Results: The two groups were homogeneous for age (p = 0.08), Body Mass Index, International Fede…
Ecological Functions in the City. Green Infraestructure In Vitoria-Gasteiz
2015
Negli anni recenti, la pianificazione ha cominciato a fare uso di una sorta di razionalità ecologica, nel disegnare le città, che ha portato all’introduzione di misure volte ad accogliere le funzioni naturali nell’ambiente urbano. Da questo punto di vista, Vitoria-Gasteiz nei Paesi Baschi (Spagna) spicca per aver cercato molto a lungo, nella sua storia, di instaurare una relazione equilibrata fra la città e il suo contesto ambientale. Il caso ha ottenuto notorietà internazionale nel 2012, quando la città è stata premiata come “European Green Capital”. Oltre a questa riconosciuta esperienza, a renderla unica è la sua posizione geografica nel Sud dell’Europa, lontano dagli esempi più noti dei…
