Capitale territoriale e partenariato pubblico-privato: un'analisi dei fattori locali di successo
2013
Al centro di una possibile tassonomia del capitale territoriale si collocano le reti di cooperazione ed, in particolare, i servizi in partenariato pubblico-privato (PPP) che rappresentano beni e servizi ad un intermedio livello di materialità e rivalità. Questa categoria di beni consente di sfruttare le complementarietà tra pubblico e privato e, attraverso un complesso meccanismo di distribuzione del rischio e dei profitti tra i soggetti coinvolti, di accrescere l’efficienza complessiva dei progetti di investimento. Nel presente lavoro sono state analizzate le possibili determinanti territoriali degli esiti dei bandi di PPP promossi in Italia. Tali determinanti riguardano aspetti relativi a…
Expression and subcellular targeting of canine parvovirus capsid proteins in baculovirus-transduced NLFK cells
2004
AbstractA mammalian baculovirus delivery system was developed to study targeting in Norden Laboratories feline kidney (NLFK) cells of the capsid proteins of canine parvovirus (CPV), VP1 and VP2, or corresponding counterparts fused to EGFP. VP1 and VP2, when expressed alone, both had equal nuclear and cytoplasmic distribution. However, assembled form of VP2 had a predominantly cytoplasmic localization. When VP1 and VP2 were simultaneously present in cells, their nuclear localization increased. Thus, confocal immunofluorescence analysis of cells transduced with the different baculovirus constructs or combinations thereof in the absence or presence of infecting CPV revealed that the VP1 protei…
Nodular morphea keloidal type: A rare case with paradigmatic histopathology significantly accompanied by a flawless surgical scar
2020
Nodular morphea is a rare variant of localized scleroderma, clinically and histopathologically characterized by cutaneous nodules or plaques associated or superimposed to the flat lesions of classic morphea. Accordingly, the association of such outgrowths with systemic sclerosis is designated as nodular scleroderma. Sometimes these lesions appear as firm, erythematous and irregularly curvy plaques resembling keloids or hypertrophic scars, thus characterizing keloidal morphea or keloidal scleroderma. These mystifying features can make the diagnosis challenging, especially in the absence of a well‐documented medical history. Here we report a case of keloidal morphea with multiple histopatholo…
La valorizzazione del patrimonio immobiliare quale leva strategica dei programmi Smart City
2014
Il lavoro propone un modello d’analisi a supporto dei processi di gestione strategica del portafoglio immobiliare degli enti locali. Esso assume il vincolo della carenza di risorse finanziarie e inquadra queste scelte nell’ambito delle iniziative “Smart City”, che consentono di coniugare la valorizzazione di questi asset immobiliari con gli obiettivi di promozione dell’innovazione e della competitività del territorio. This paper provides a theoretical model aimed at supporting the decision-making process for public real estate portfolio management. In a context of enduring financial constraints, Local Governments could manage the aforementioned process under the framework of the “Smart City…
Understanding the mechanism of non-polar diels-alder reactions. A comparative elf analysis of concerted and stepwise diradical mechanisms
2010
The electron-reorganization along the concerted and stepwise pathways associated with the non-polar Diels-Alder reaction between cyclopentadiene (Cp, 1) and ethylene (2) has been studied using the topological analysis of the electron localization function (ELF) at the B3LYP/6-31G(d) level of theory. ELF results for the concerted mechanism stresses that the electron-reorganization demanded on the diene and ethylene reagents to reach two pseudo-diradical structures is responsible for the high activation energy. A comparative ELF analysis of some relevant points of the non-polar Diels-Alder reaction between Cp and styrene (10) suggests that these concerted mechanisms do not have a pericyclic e…
Azo-hydrazo conversion via [1,5]-hydrogen shifts. A combined experimental and theoretical study
2012
Abstract Azoalkenes 6e , 6g , 6h , and 8c underwent an easy azo-hydrazo conversion via a [1,5]-hydrogen shift yielding α,β-unsaturated hydrazones. The isomerization products were characterized through spectroscopic and spectrometric techniques. In order to understand the nature of the mechanism of these [1,5]-hydrogen shifts, the transition state structures of the reactions were theoretically studied at the B3LYP/6-31G(d,p) level. Substitution effects in the propenylazo system on the kinetic and thermodynamic parameters were analyzed. An electron localization function (ELF) analysis of the electronic structure of the transition state structure associated with the azo-hydrazo conversion of t…
La industria exógena en la periferia occidental del área metropolitana de Valencia (A.M.V.)
1991
En el tejido industrial de las comarcas occidentales del A. M. V., el Camp de Túria y la Hoya de Buñol-Chiva, hallamos una dualismo respecto al origen de los establecimientos industriales ubicados en ambas comarcas: la industria autóctona y la actividad fabril foránea. Tras analizar los factores que condicionan la localización de estas industrias exógenas definiremos qué rasgos las caracterizan así como el nivel de integración con respecto al espacio que las acoge. En la industria foránea hemos diferenciado aquellos establecimientos industriales que se han instalado tras un traslado de aquéllos otros de nueva creación producto de la iniciativa foránea
When are thin films of metals metallic? Part III
1996
Abstract A large amount of experimental information has indicated that very thin films of metallic elements can exhibit nonmetallic behavior, even on metal substrates. These films undergo a gradual nonmetal to metal transition with increasing film density or thickness. The nonmetallic behavior can be related to electron localization due to strong electron-electron correlation in low dimensional systems, as indicated by the strong enhancement of electron effective mass. The evolution in the electronic structure associated with the nonmetal to metal transition bears a striking resemblance to the behavior observed for free metal clusters. Part I [1], outlined the general concepts of a nonmetal…
Direct measurement of optical losses in plasmon-enhanced thin silicon films (Conference Presentation)
2018
Plasmon-enhanced absorption, often considered as a promising solution for efficient light trapping in thin film silicon solar cells, suffers from pronounced optical losses i.e. parasitic absorption, which do not contribute to the obtainable photocurrent. Direct measurements of such losses are therefore essential to optimize the design of plasmonic nanostructures and supporting layers. Importantly, contributions of useful and parasitic absorption cannot be measured separately with commonly used optical spectrophotometry. In this study we apply a novel strategy consisting in a combination of photocurrent and photothermal spectroscopic techniques to experimentally quantify the trade-off betwee…
Non-Markovian dynamics from band edge effects and static disorder
2017
It was recently shown [S. Lorenzo et al., Sci. Rep. 7, 42729 (2017)] that the presence of static disorder in a bosonic bath - whose normal modes thus become all Anderson-localised - leads to non-Markovianity in the emission of an atom weakly coupled to it (a process which in absence of disorder is fully Markovian). Here, we extend the above analysis beyond the weak-coupling regime for a finite-band bath so as to account for band edge effects. We study the interplay of these with static disorder in the emergence of non-Markovian behaviour in terms of a suitable non-Markovianity measure.
