    The purpose of this work is to propose a working suggestion for all professional, that, within the school, meet people with sensory and intellectual disabilities on a daily basis. First, the characteristics of the different disabilities are illustrated, then the adapted activities are described. Activities adapted are, by definition inclusive, promote optimal living conditions and a good system of relationships. Through sport, in fact, people with disabilities could feel part of the community and its network of relationships. Nowadays everyone can practice sports, having the opportunity to try their hand in various disciplines. Sport is an important educational tool that, through targeted actions, becomes fundamental for emancipation and growth. This work was born out of the need to help children with intellectual and sensory disabilities in everyday life, through motor activity, setting as objectives the improvement of motor skills, attention, concentration, and of the basic motor schemes, the psychic, intellectual and sensory conditions, the strengthening of relationships with others, in particular with peers, the development of self-discovery and confidence in one’s own abilities and autonomy in daily activities.Lo scopo di questo lavoro è di proporre un suggerimento di lavoro per tutte le figure professionali, che all’interno della scuola, incontrano ogni giorno persone con disabilità, sia di tipo sensoriale che di tipo intellettivo. Innanzitutto vengono illustrate le caratteristiche delle diverse disabilità, successivamente si descriveranno le attività adattate. Le attività adattate per definizione sono inclusive, promuovono condizioni di vita ottimali e un buon sistema di relazioni. Attraverso l'inclusione dello sport, infatti, le persone con disabilità possono sentirsi parte della comunità e della sua rete di relazioni. Oggi tutti possono praticare sport, avendo la possibilità di cimentarsi in varie discipline. Lo sport come importante strumento educativo che, attraverso azioni mirate, diventa uno strumento fondamentale di emancipazione e crescita. Il lavoro è nato dalla necessità di aiutare i ragazzi con disabilità intellettiva e sensoriale nella vita di tutti i giorni, attraverso l’attività motoria, ponendosi come obiettivi il miglioramento delle capacità motorie, dell’attenzione, della concentrazione, e degli schemi motori di base, delle condizioni psichiche, intellettive e sensoriali, il rafforzamento delle relazioni con gli altri, in particolare con i coetanei, lo sviluppo della scoperta di se stessi e della fiducia nelle proprie possibilità e dell’autonomia nelle attività quotidiane

    Direct transition from quantum escape to phase diffusion regime in YBaCuO biepitaxial Josephson Junctions

    Full text link
    Dissipation encodes interaction of a quantum system with the environment and regulates the activation regimes of a Brownian particle. We have engineered grain boundary biepitaxial YBaCuO junctions to drive a direct transition from quantum activated running state to phase diffusion regime. The cross-over to the quantum regime is tuned by the magnetic field and dissipation is encoded in a fully consistent set of junction parameters. To unravel phase dynamics in moderately damped systems is of general interest for advances in the comprehension of retrapping phenomena and in view of quantum hybrid technology

    Coherent transport in extremely underdoped Nd1.2Ba1.8Cu3Oz nanostructures

    Full text link
    Proximity-effect and resistance magneto-fluctuations measurements in submicron Nd1.2Ba1.8Cu3Oz (NBCO) nano-loops are reported to investigate coherent charge transport in the non-superconducting state. We find an unexpected inhibition of cooper pair transport, and a destruction of the induced superconductivity, by lowering the temperature from 6K to 250mK. This effect is accompanied by a significant change in the conductance-voltage characteristics and in the zero bias conductance response to the magnetic field pointing to the activation of a strong pair breaking mechanism at lower temperature. The data are discussed in the framework of mesoscopic effects specific to superconducting nanostructures, proximity effect and high temperature superconductivity.Comment: to appear on new journal of Physic

    Approccio didattico nei disturbi del movimento

    In recent years, scientific research has placed a great deal of attention on the observation of children with developmental coordination disorder (DCD). The severe difficulty in motor coordination that such children exhibit also particularly interferes with school performance and activities of daily living. In fact, symptoms of DCD occur already in the initial phase of development, but it is often not identified until school age, leaving out good opportunities for early intervention. These children have previously been described with a variety of terms such as developmental dyspraxia, minimal brain dysfunction,perceptual-motor dysfunction, physical embarrassment, or, more commonly, clumsy baby syndrome. The purpose of this work, in the light of the scientific framework illustrated, is to educate children with this syndrome to a motor creed that is able to improve their movement and consequently their ability to manage the body.Negli ultimi anni le ricerche scientifiche hanno posto una grande attenzione sull’osservazione dei bambini con disturbo dello sviluppo della coordinazione (DCD). La grave difficoltĂ  nella coordinazione motoria che tali bambini mostrano interferisce particolarmente anche con il rendimento scolastico e le attivitĂ  della vita quotidiana. Infatti si verificano sintomi di DCD giĂ  nella fase iniziale dello sviluppo, ma spesso non viene identificato fino all’etĂ  scolare, lasciando perdere buone opportunitĂ   d’intervento precoce. Questi bambini sono stati precedentemente descritti con una varietĂ  di termini come disprassia evolutiva, disfunzione cerebrale minima, disfunzione percettivo-motorio, imbarazzo fisico o, piĂą comunemente, la sindrome del bambino goffo. Lo scopo di questo lavoro, alla luce del quadro scientifico illustrato, è quello di istruire i bambini che presentano tale sindrome ad un credo motorio che sia in grado di migliorare il loro movimento e di conseguenza la loro capacitĂ  di gestire il corpo.&nbsp

    Quantum crossover in moderately damped epitaxial NbN/MgO/NbN junctions with low critical current density

    Full text link
    High quality epitaxial NbN/MgO/NbN Josephson junctions have been realized with MgO barriers up to a thickness of d=1 nm. The junction properties coherently scale with the size of barrier, and low critical current densities down to 3 A/cm2^2 have been achieved for larger barriers. In this limit, junctions exhibit macroscopic quantum phenomena for temperatures lower than 90 mK. Measurements and junction parameters support the notion of a possible use of these devices for multiphoton quantum experiments, taking advantage of the fast non equilibrium electron-phonon relaxation times of NbN
