Dung application increases CH4 production potential and alters the composition and abundance of methanogen community in restored peatland soils from …
2018
Peatland restoration via rewetting aims to recover biological communities and biogeochemical processes typical to pristine peatlands. While rewetting promotes recovery of C accumulation favorable for climate mitigation, it also promotes methane (CH4) emissions. The potential for exceptionally high emissions after rewetting has been measured for Central European peatland sites previously grazed by cattle. We addressed the hypothesis that these exceptionally high CH4 emissions result from the previous land use. We analyzed the effects of cattle dung application to peat soils in a short- (2 weeks), a medium- (1 year) and a long-term (grazing) approach. We measured the CH4 production potentials…
Sinkholes risk analysis: case history of Marsala (Sicily, Italy)
2006
Given the increasing phenomenon of Sinkholes all over Italy, the Gruppo Nazionale per la Difesa dalle Catastrofi Idrogeologiche (G.N.D.C.I) and the Dipartimento della Protezione Civile (D.P.C.), during 2004, started a plan called Sinkholes dedicated to the phenomena in Italy. The plan provides the publication of the database realized by the D.P.C. by means of the census of beyond 1000 cases scattered across the nation. The city of Marsala is strongly characterized by the presence of a great number of Calcarenite cavities. The material object of extraction is the Calcarenite di Marsala of the Pleistocene, frequently used in the construction of buildings. The presence of the underground cavit…
Stato dell’arte degli interventi sul mezzo recettore e di propagazione per la mitigazione delle vibrazioni generate da sistemi di trasporto su ferro
2008
La generazione e la propagazione delle onde vibrazionali da una sorgente, ferroviaria o tranviaria, all’ambiente circostante è un problema complesso che risulta influenzato da vari fattori tra loro correlati: le caratteristiche e le condizioni della sovrastruttura, il peso, la velocità e le caratteristiche meccaniche del veicolo, le proprietà dinamiche e stratigrafiche del terreno, le caratteristiche dinamiche degli edifici recettori. Di tali aspetti occorre tenere conto ai fini della realizzazione di efficaci misure di mitigazione. Nella presente memoria vene riportato lo stato dell’arte relativo agli interventi sul mezzo di propagazione (suolo e sottosuolo) e sul mezzo recettore (opere di…
Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application
2021
This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…
Learning Automata-based Misinformation Mitigation via Hawkes Processes
2021
AbstractMitigating misinformation on social media is an unresolved challenge, particularly because of the complexity of information dissemination. To this end, Multivariate Hawkes Processes (MHP) have become a fundamental tool because they model social network dynamics, which facilitates execution and evaluation of mitigation policies. In this paper, we propose a novel light-weight intervention-based misinformation mitigation framework using decentralized Learning Automata (LA) to control the MHP. Each automaton is associated with a single user and learns to what degree that user should be involved in the mitigation strategy by interacting with a corresponding MHP, and performing a joint ra…

Forest bioenergy harvesting changes carbon balance and risks biodiversity in boreal forest landscapes
2020
Climate solutions relying on forest bioenergy may be in conflict with carbon sequestration and storage by forests as well as conservation of biodiversity. We quantified effects of forest-residue harvesting for bioenergy on both forest carbon balance and biodiversity in a boreal forest landscape. Through a modeling framework, we simulated forest development in four real watersheds with three scenarios: (i) with and (ii) without forest-residue harvesting and (iii) set aside to study the conservation potential of these landscapes in the future without management. We simulated changes in the forest carbon stocks and in the quality and quantity of deadwood resources for 100 years and combined t…

Data from: Optimizing management to enhance multifunctionality in a boreal forest landscape
2016
1. The boreal biome, representing approximately one third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for increased timber production with provisioning of other ecosystem services and biodiversity. However, there is still little knowledge about how forest management could help solve this challenge. Hence, studies that investigate how to manage forests to reduce trade-offs between ecosystem services and biodiversity are urgently needed to help forest owners and policy-makers take informed decisions. 2. We applied seven alternative forest management regimes using a forest growth simulator in a…
Resilience between mitigation and adaptation
2020
The relation between architecture and time is the subject of two papers. The first illustrates the variations this relationship can make on the notion of resilience, applying it to architectural design and current experimentations of Design for Disassembly. The second focuses on the important subject of population ageing and on the need to study and develop forward-looking forms of a sustainable elderly-friendly living environment in Bulgaria, suggesting potential directions for future development in the context of a resilient society. Finally, the book includes an essay dealing with the importance of new digital technologies in the transition towards a resilient and sustainable city: the d…
