La Ligue du Nord : le retour ambigu de l’identité territoriale sur la scène politique italienne

open access: yesL'Espace Politique, 2011
The North League (Lega Nord) is now and for the third time in its short history part of a coalition government led by Silvio Berlusconi. Its political program advocates the transformation of Italy into a federal state with fiscal federalism for more ...

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

A Defence of Separatism

open access: yes, 2011
Philosophers commonly distinguish between an experience’s intentional content—what the experience represents—and its phenomenal character—what the experience is like for the subject.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Catalan Nationalism and Challenges to the Territorial Integrity of Spain

open access: yesСравнительная политика, 2016
At the beginning of the 21st century Spain faced a number of challenges, primarily the growth of separatist sentiments in the regions fraught with the danger of its fragmentation on ethno-national basis.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Separatism — the Main Threat for Internal Security

open access: yes, 2019
This article is devoted to separatism as a global phenomenon of modern times. Separatism is considered a large-scale phenomenon of the present, which can cause irreparable consequences for state independence.
