The Emergence of Chaos in Quantum Mechanics

2020

Nonlinearity in Quantum Mechanics may have extrinsic or intrinsic origins and is a liable route to a chaotic behaviour that can be of difficult observations. In this paper, we propose two forms of nonlinear Hamiltonian, which explicitly depend upon the phase of the wave function and produce chaotic behaviour. To speed up the slow manifestation of chaotic effects, a resonant laser field assisting the time evolution of the systems causes cumulative effects that might be revealed, at least in principle. The nonlinear Schr&ouml

Stochastic dynamics and mean field approach in a system of three interacting species

2008

The spatio-temporal dynamics of three interacting species, two preys and one predator, in the presence of two different kinds of noise sources is studied. To describe the spatial distributions of the species we use a model based on Lotka-Volterra equations. A correlated dichotomous noise acts on \beta, the interaction parameter between the two preys, and a multiplicative white noise affects directly the dynamics of each one of the three species. We study the time behaviour of the three species in single site for different values of the multiplicative noise intensity, finding noise-induced oscillations of the three species densities with an anticorrelated behaviour of the two preys. Afterwar…

Nanowire Ordered Arrays for Electrochemical Sensing of H2O2

2016

Today, electrochemical sensors are considered very interesting in comparison to conventional techniques because they are very adaptable, cheap, have very low limit of detection and low detection time. The most used electrochemical technique is the amperometry . In amperometric sensors, a fixed potential is applied to the electrochemical cell, and a corresponding current, due to a reduction or oxidation reaction, is then obtained. This current it can be correlated with the bulk concentration of the detecting species (the solute) such as H2O2. Hydrogen peroxide is an essential mediator in food, pharmaceutical, clinical, industrial, and environmental analyses therefore, it is of great importan…

Pd-NWs ordered arrays for electrochemical sensing of H2O2

2016

In this work, we present the performance of nanostructured array of Pd (Pd-NWs) for electrochemical sensors of hydrogen peroxide. Hydrogen peroxide is widely used in several fields, because to its oxidizing and reducing properties, like for treatment of waste water, paper and contaminated soils, as reagent in many chemical industries or like rocket propellant [1]. Furthermore, its presence or absence may be connected with many neurological deseases or/and with cancer [2].Today the most used methods for detection of that chemical are IR spectroscopy, spectrophotometry, fluorimetry, chemioluminescence and redox titration. However these methods are often uneconomical, have very high detection …

A MAS metamodel-driven approach to process fragments selection

2009

The construction of ad-hoc design processes is more and more required today. In this paper we present our approach for the construction of a new design process following the Situational Method Engineering paradigm. We mainly focus on the selection and assembly activities on the base of what we consider a key element in agent design processes: the MAS metamodel. The paper presents an algorithm establishing a priority order in the realization (instantiation) of MAS metamodel elements by the fragments that will compose the new process.

Il danno da perdita del rapporto parentale negli ordinamenti stranieri e la sua compatibilità con il principio dell'ordine pubblico: raffronti compar…

2021

The essay deals with the damage caused by loss of parental relationship and how it is regulated in various foreign legal systems. In particular, it will analyze the evolution of the Italian concept of the limit of “ordine pubblico”, as regulated by L. 218/1995, through a jurisprudence analysis and it will be highlighted that there is a hard core of this concept, which is linked to the protection of fundamental human rights, which cannot be affected by any foreign legal system. Finally, it will be seen how also the regulation of damages caused by the loss of parental relationship, being related to the protection of fundamental human rights, is intimately connected with the concept of “ordine…

Ordini di protezione contro gli abusi familiari, bilanciamento degli interessi e primato della Persona

2022

The substantive and procedural instrument of protection orders, consisting of articles 342-bis and ter of the Italian Civil Code as well as of article 736 of the Italian Code of Civil Procedure, not only constitutes a clear example of grafting the remedial perspective within family relationships, but it is also representative of the reorientation of family relationships in the sign of the primacy of the Person. This is the central thesis of the essay, that the Author argues by pointing out how the dynamics of the remedy in question, even in compliance with the principle of balancing the opposing interests, reveals an unconditional primacy of the individual dimension over any counterweights …

Istruttoria tecnico-scientifica nel giudizio a quo e giudizio di legittimità costituzionale: il caso dell’obbligo vaccinale nella decretazione d’urge…

2022

Muovendo dall’ordinanza n. 38 del 2022 del Consiglio di giustizia amministrativa per la Regione siciliana (CGARS), il contributo si sofferma a) sull’estensione per analogia degli obblighi vaccinali; b) su oscurità ed incoerenze della disciplina sugli obblighi vaccinali in tema di accesso alle strutture socio-sanitarie. Il contributo si incentra poi sull'istruttoria tecnico-scientifica e la motivazione sulla non manifesta infondatezza delle questioni di legittimità costituzionale aventi ad oggetto la disciplina sull'obbligo vaccinale e sugli aspetti problematici dell'ordinanza di rimessione del CGARS.
