Reduction of oxygen to H2O2 at carbon felt cathode in undivided cells. Effect of the ratio between the anode and the cathode surfaces and of other op…

2019

Abstract In the last years, the electrochemical conversion of oxygen to hydrogen peroxide at carbon felt has been largely studied in order to define a new route for the production of H2O2 and to optimize the electro-Fenton process, which is based on the cathodic generation of H2O2. In particular, many studies regarding electro-Fenton process were carried out in undivided cells in order to avoid the costs of the separator and to reduce the cell potentials. Hence, in order to optimize the cathodic conversion of oxygen to H2O2 in undivided cells, the effect of many parameters linked to the anodic process were here evaluated. In particular, it was demonstrated that the performances of the proce…

Optimal Local Routing Strategies for Community Structured Time Varying Communication Networks

2017

International audience; In time varying data communication networks (TVCN), traffic congestion, system utility maximization and network performance enhancement are the prominent issues. All these issues can be resolved either by optimizing the network structure or by selecting efficient routing approaches. In this paper, we focus on the design of a time varying network model and propose an algorithm to find efficient user route in this network. Centrality plays a very important role in finding congestion free routes. Indeed, the more a node is central, the more it can be congested by the flow coming from or going to its neighborhood. For that reason, classically, routes are chosen such that…

Decision making in multiobjective optimization problems under uncertainty: balancing between robustness and quality

2018

As an emerging research field, multiobjective robust optimization employs minmax robustness as the most commonly used concept. Light robustness is a concept in which a parameter, tolerable degradations, can be used to control the loss in the objective function values in the most typical scenario for gaining in robustness. In this paper, we develop a lightly robust interactive multiobjective optimization method, LiRoMo, to support a decision maker to find a most preferred lightly robust efficient solution with a good balance between robustness and the objective function values in the most typical scenario. In LiRoMo, we formulate a lightly robust subproblem utilizing an achievement scalarizi…

Gli aspetti fiscali delle attività di rigenerazione e riuso di beni a fini di interesse generale.

2017

E’ possibile attribuire un riconoscimento, una legittimazione ed una regolamentazione giuridica all'opera prestata dai privati nell'attività di rigenerazione e riuso di beni di interesse comune? La leva fiscale può essere considerata come strumento per favorire lo sviluppo di queste attività? Alla prima domanda possiamo rispondere che il concetto, oggi in evoluzione, di sussidiarietà orizzontale, sembra essere lo strumento più idoneo per inquadrare giuridicamente le azioni di privati cittadini che volontariamente decidono di prendersi cura di beni comuni ai più diversi livelli (beni immobili o mobili concernenti il patrimonio artistico/culturale o, più in generale, fruibili da una collettiv…

May we give legitimacy and a legal shape to citizens' activities directed to regeneration and re-use of goods of common interest? Taxation (i.e. tax expenses) can encourage these activities? We may answer the first question that the evolving concept of the so said “sussidiarietà orizzontale” seems to be the most appropriate tool to give the actions of private citizens directed to take care of common goods (i.e. cultural heritage or goods that can be used by a given community) a legal framework. To answer the second question we have to face the issue concerning the relationship between taxation and “sussidiarietà orizzontale” notably if tax expenses can be considered in any way a developing tool for the latter. This paper aim to face these issues.Settore IUS/12 - Diritto Tributario

The effect of meal size on the rate of gastric evacuation of burbot, Lota lota (L.)

1999

– The effect of meal size on the gastric evacuation rate of burbot Lota lota (L.), was determined at a constant temperature of 1.5°C. Burbot were fed vendace Coregonus albula (L.), in varying amounts from 1.0% to 12.6% of burbot weight. Although gastric evacuation rate decreased exponentially with increasing meal size, the absolute amount of food evacuated per day (g. day−1 increased when meal size increased. The estimated maximum daily gastric evacuation rates were 0.8, 1.3 and 1.6 g/day with meal sizes 1%, 5% and 10% of burbot weight (200 g). No difference in gastric evacuation rate was observed between meals of the same size (8 g) but which consisted of either one or three vendace.

Accelerating Application Migration in HPC

2016

It is predicted that the number of cores per node will rapidly increase with the upcoming era of exascale supercomputers. As a result, multiple applications will have to share one node and compete for the (often scarce) resources available on this node. Furthermore, the growing number of hardware components causes a decrease in the mean time between failures. Application migration between nodes has been proposed as a tool to mitigate these two problems: Bottlenecks due to resource sharing can be addressed by load balancing schemes which migrate applications; and hardware errors can often be tolerated by the system if faulty nodes are detected and processes are migrated ahead of time.

Shining castles and humans of metal/floral appearance ? metaphorical language in the Palaiologan romances Kallimachos and Velthandros

2019

About eight centuries after Heliodorus, the Greek novel resurfaced in the twelfth century, in Komnenian Byzantium, and again two centuries later under the Palaiologan dynasty. This latter literary revival was due to the political stability of the imperial Byzantine government, which promoted cultural production, rhetorical education, and patronage networks. Kallimachos and Velthandros, two Palaiologan romances presented as court literature, combine ancient and medieval tropes with rhetorical artistry to blur the boundaries between the artificial and the natural. Castles and objects made of precious metals thus resemble living, natural spaces, and human characters are portrayed in metallurgi…

ESPERIRE MIMETICO E RAZIONALITÀ NEL MODELLO ADORNIANO DI RAPPORTO MENTE-MONDO.

2014

Il saggio ricostruisce il ruolo cognitivo e razionale della mimesi nel modello adorniano di conoscenza come “differenziazione”. Vi è proposta un’interpretazione della capacità del “pensare per costellazioni” e del linguaggio di “cogliere la cosa”, che ne evidenzia la lontananza dal “vecchio realismo della rappresentazione oggettiva (der alte Abbildrealismus)”. Esso mira anche a rendere esplicito come il modello adorniano di conoscenza sia in grado di dar conto di alcune recenti acquisizioni neurofisiologiche su un livello mimetico di rapporto mente-mondo, e come esso contribuisca ad una convincente interpretazione, razionalista ed antiintellettualista ad un tempo, di alcune loro implicazion…
