Modeling the hydrological and mechanical effect of roots in shallow landslide analysis
2015
The additional cohesion exercised by vegetation roots (cr) provides an important contribution to the slope stability. This study proposes a methodology for estimating the cr term in a hillslope landslide analysis within a coupled ecohydrological-stability model. The coupled model simulates the spatial distribution and temporal dynamics of the Factor of Safety (FS) as a function of soil moisture dynamics, by taking into account the hydrological effects of vegetation through the root water uptaking. The additional mechanical root cohesion is estimated in a Fiber Bundle Model framework that allows for the evaluation of the root strength as a function of stress-strain relationships of populatio…
Hydrological and mechanical effects of roots in shallow landslide analysis: A physically-based approach
2015
This study provides the first insights of a methodology for estimating the additional cohesion exercised by vegetation roots in a hillslope landslide analysis within a coupled ecohydrological-stability model. The existing coupled system is able to simulate the spatial distribution and temporal dynamics of Factor of Safety (FS) as a function of soil moisture dynamics. The model takes into account the hydrological effects of vegetation which, through the root water uptaking, contributes in reducing the soil water content and, thus, in increasing the slope stability. The additional mechanical root cohesion is estimated in a Fiber Bundle Model (FBM) framework that allows for the evaluation of t…

European cohesion principle and the institutional and economic development of an insular region: the case of Sicily1
2018
This paper is a tribute dedicated to the memory of Alessandro Argiroffi, professor of philosophy of law and human rights, colleague of the University of Palermo. It was presented at the Local Economic Development Program at the London School of Economics and Political Science - New Academic Building - London March 7, 2015 for the first time, and than in Bilbao, at the Conference “Significado y funcíon de las regiones con autogobierno y parlamentos legislativos en la construccion de la Europa política” organized by Universidad del País Vasco/Euskal Herriko Unibertsitatea, October 10‐11, 2017
The effect of Ag, Pb and Bi impurities on grain boundary sliding and intergranular decohesion in Copper
2016
We investigate the changes in grain boundary sliding (GBS) and intergranular decohesion in copper (Cu), due to the inclusion of bismuth (Bi), lead (Pb) and silver (Ag) substitutional impurity atoms at a $\Sigma$5 (0 1 2) symmetric tilt grain boundary (GB), using a first-principles concurrent multiscale approach. We first study the segregation behavior of the impurities by determining the impurity segregation energy in the vicinity of the GB. We find that the energetically preferred sites are on the GB plane. We investigate the intergranular decohesion of Cu by Bi and Pb impurities and compare this to the effect of Ag impurities by considering the work of separation, $W_s$ and the tensile st…
EU cohesion aid to Spain: a data set. Part I: 2000-06 planning period
2010
In this paper we construct a data set on EU cohesion aid to Spain during the planning period 2000-06. The data are disaggregated by region, year and function and attempt to approximate the timing of actual executed expenditure on assisted projects.

Wsparcie rozwoju klastrów w Polsce w perspektywie finansowej 2014-2020
2017
Klastry stanowią istotny element każdej gospodarki. Obecność struktur klastrowych w gospodarce świadczy bowiem o poziomie jej rozwoju, a także wskazuje na jej potencjał oraz dalsze perspektywy rozwojowe. Ze względu na różnorodność struktur klastrowych nie ma dla wszystkich jednolitego zestawu instrumentów wspierających ich rozwój. Konieczne jest stosowanie różnych, odpowiednio dostosowanych do danego typu klastra instrumentów. Celem opracowania jest przedstawienie możliwości uzyskania przez klastry dofinansowania w ramach budżetu na lata 2014-2020.
