L’ampio potere di regolazione dell’Autorità indipendente dei trasporti nel settore ferroviario
2018
The wide regulatory power of the Independent Transport Authority on the railway sector The National Independent Authority for Transport, imposed by European Law and established in Italy in 2013, is characterized by using wide powers of control, regulation and sanction, which cover all transport sectors. Regulatory competences seem in particular to interfere, in some areas, with the functions, also of political direction, of the State, Regional and Local Government, as well as the competences of the other administrative independent bodies such as the National Antitrust Authority or National Anti-Corruption Authority. This requires the provision of forms of coordination and cooperation beetwe…
Brevi note sulla qualificazione giuridica dei beni costituenti la rete ferroviaria
2018
The paper synthetically describes how Italian courts and scholars interpreted the legal transformations occurred to the railway market, and notably to the rail-network infrastructure components property regulation, since the end of the twentieth century. The authors contest the (prevailing) opinion assuming a substantial continuity between the current stage of regulation and the regime of public property provided by 1942 civil code; they show the reasons why, on the contrary, the rail-network components have to be considered as goods subject to private property law both on the formal and the substantial floor. For this purpose, the paper emphasize how the public interests aimed by the previ…
Il quadro degli interventi avviati e programmati in sicilia a favore della sicurezza stradale
2014
Il volume intende illustrare il tema della sicurezza stradale nelle sue molteplici dimensioni e in maniera trasversale, con uno specifico approfondimento per la Sicilia, mettendo a disposizione un'ampia selezione di informazioni qualitative e quantitative per specifiche analisi sulla sicurezza stradale, utili ai policy maker per intraprendere azioni di programmazione a livello locale. L'Italia registra un elevato tasso di mortalità rispetto alla media europea, una lenta riduzione del numero di vittime per incidente stradale e marcati divari territoriali. Nel contesto nazionale questo studio descrive poi l'evoluzione del fenomeno dell'incidentalità in Sicilia nell'ultimo decennio, individuan…

Tuning size and thermal hysteresis in bistable spin crossover nanoparticles.
2010
Nanoparticles of iron(II) triazole salts have been prepared from water-organic microemulsions. The mean size of the nanoparticles can be tuned down to 6 nm in diameter, with a narrow size distribution. A sharp spin transition from the low spin (LS) to the high spin (HS) state is observed above room temperature, with a 30-40-K-wide thermal hysteresis. The same preparation can yield second generation nanoparticles containing molecular alloys by mixing triazole with triazole derivatives, or from metallic mixtures of iron(II) and zinc(II). In these nanoparticles of 10-15 nm, the spin transition "moves" towards lower temperatures, reaching a 316 K limit for the cooling down transition and mainta…
Annotazioni sull’elenco dei giogali d’argento del cavaliere trapanese Fra’ Alessio di Ferro
2019
The article deals with the inventory of 1763 of the giogali owned by the knight of Saint John Fra' Alessio di Ferro, which is located in the State Archives in Trapani. In particular, these are some notes relating to the silver items in his possession. Alessio di Ferro was an illustrious exponent of one of the most prominent families in the centuries of the city of Trapani linked to the island of Malta.
Reinvestigation of the Pd-catalysed bis(silylation) of alkynes with 1,1,2,2-tetramethyl-1,2-bis(phenylthiomethyl)disilane: Unexpected formation of th…
2013
International audience; The bis(silylated) alkenes Z-(PhSCH2)Me2SiC(H)=C(Fc)SiMe2(CH2SPh) (2) and Z-(PhSCH2)Me2SiC(H)=C(bipheny)SiMe2(CH2SPh) (3) have been prepared by Pd-catalysed double silylation of ethynylferrocene and 4-ethynyl-1,1'-biphenyl in the presence of 1,1,2,2-tetramethyl-1,2-bis(phenylthiomethyl)disilane (1). A reinvestigation on the interaction of 1 with [PdCl2(PhCN)2] in technical-grade CH2Cl2 as solvent revealed competition between reduction to elemental palladium (due to oxidative addition of the Si-Si bond across Pd(II) and subsequent reductive elimination) and formation of an unusual eight-membered chelate complex cis-[PdCl2{(PhSCH2SiMe2)2O}] (4), which is fluxional in s…

Environmental analysis of different construction techniques and maintenance activities for a typical local road
2017
Abstract In this paper, considering the sever impact of road infrastructures on both the surrounding environment as well as on the consumption of locally available natural resources, different road construction techniques have been studied and compared, in order to be able to rank the best solution in terms of environmental sustainability. For the aims of this study, a Life Cycle Analysis has been carried out on a road infrastructure with the most representative geometrical characteristics among those widely used in Italy, in suburban areas, with the help of an appropriate software, the PaLATE. The environmental effects due to both the use of recycled materials, such as the Reclaimed Asphal…
