Diritto privato. Casi e materiali
No full textSi tratta di una raccolta di sentenze recenti di varie tematiche sul diritto privato oggetto del corso di Istituzioni di diritto privato insegnato nella facoltà di Giurisprudenza per la laurea triennale in Scienze dei servizi giuridici, in cui gli studenti anelano ad imparare a trattare anche dei casi pratici.
Nel volume gli Autori con uno schema unitario, trattano il caso pratico dopo un’introduzione istituzionale sull’istituto di riferimento per il caso giurisprudenziale, in modo da conoscere, prima della lettura della sentenza le regole ed i principi fondamentali dell’argomento in questione, in successione il testo della sentenza con evidenziati i passaggi cruciali della pronuncia ed il commento rapido alla sentenza per comprenderne al meglio i principi e le conclusioni.
Esso si propone di essere un rapido ed utile strumento per le matricole per introdurle alla conoscenza, alla miglior comprensione di un testo giuridico, per insegnare loro come si affronta lo studio di una sentenza
Angular calibration in energy dispersive X-Ray diffraction by using genetic algorithms
No full textIn Energy Dispersive X-Ray diffraction measurements, the estimate of momentum transfer q, on which the diffracted intensity depends, should be as accurate as possible. Since q, in turn, depends on both the energy and the scattering angle, an error on the latter due to an incorrect positioning of the sample, to the asymmetric angular spread induced by the collimation slits or, in general, to any uncertainty on the geometric setup, results in an uncertainty on the q value. Here, a new self calibration method to correct such errors, based on a genetic algorithm is presented. It is robust, fast and completely automatic. Results obtained by carrying out Energy Dispersive X-Ray Diffraction measurements on reference samples are reported and discussed. They show how the application of such genetic algorithm may provide a fast esteem of the two parameters required when multiple angle pattern collection is performed, namely the effective starting angle and the angular step. In this way, reliable q-values of all the diffraction pattern features (Bragg peaks for crystalline, and diffused bumps for non-crystalline samples) are obtained
Selective energy dispersive diffraction peak fitting by using genetic algorithm RID F-3370-2011
No full textAccurate and precise estimates of X-Ray diffraction peak parameters is mandatory, when small dynamic changes of lattice parameters have to be quantitatively analyzed. To follow in real time such changes, a large set of patterns must be usually collected, so that the position of certain peaks of interest can be tracked. To calculate the positions, a fitting procedure of the peaks is required and several algorithms are reported in the literature for this purpose. However, these algorithms are mainly focused on the determination of parameters based on a model of the cell geometry. Here, we present a new algorithm allowing to carry out the fitting procedure on a portion only of the pattern, with neither tight constraints on the dataset, nor restrictive hypotheses on the sample structure. In our case, a coarse estimate of the detector resolution and of the positions of the peaks to fit are the only initial conditions required. This method can be regarded as a hybrid technique, as it makes use of a genetic algorithm approach, mixed with an intensive multiple random generation of the population, that makes it similar to a Monte Carlo technique. Moreover, adaptive genetic operators have been implemented in the data processing code. These properties result in a fast and efficient algorithm, a fundamental requirement when, as in the present case, the Energy Dispersive X-ray Diffraction method is applied to observe structural changes, which implies the acquisition of many patterns in a relatively short time. The result of this application is shown by some practical examples

Subsequently, he conducted peripatetic learning in Murid areas of northern Senegal. Later, he settled in the village of Sare Pathe-Bailo near the city of Kolda where he serves as Imam.Images taken of manuscript owner Imam Issa Diante and his community of Sare Pathe-Bailo, Kolda, Senegal, for the manuscript digitization work done in July 2018
La regulación de las nanotecnologías en Argentina
No full textEste trabajo se enmarca en una línea de los Estudios Sociales de la Ciencia y la Tecnología (ESCT) que estudia las relaciones entre derecho, democracia y nanotecnologías. Se analiza la experiencia de regulación de las nanotecnologías en Argentina en el período 2001-2017, a partir del rastreo y procesamiento de proyectos legislativos, iniciativas institucionales y discursos expertos comprometidos en la coproducción de un saber científico/jurídico “nano”. Se identificaron dos grandes etapas. En la primera etapa (2001-2006) se aborda el proceso que lleva a la creación por decreto de la Fundación Argentina de Nanotecnología (FAN) y se reseñan las críticas que recibió el modelo adoptado. En la segunda etapa (2007 en adelante), que inicia con la creación del Ministerio de Ciencia, Tecnología e Innovación Productiva (MINCyT), se estudia un modelo de gobierno “nano” que combina la institucionalidad experta y la estandarización normativa global. Se concluye que el carácter inestable y polisémico de los nano-objetos posiciona distintos tipos de conocimiento como mediadores de los formatos regulatorios e institucionales. En este sentido, el trabajo pretende contribuir: a) en general, a las discusiones actuales sobre los modos que tiene el derecho de estabilizar objetos controvertidos; b) en particular, a describir cómo los operadores legales visualizan a los nano-objetos en Argentina
