Tra autorappresentazione, cronaca e negozio spirituale. Il trattato del mercedario Ignazio Vidondo e la redenzione di Algeri del 1654
No full text"Il saggio, composto da Sara Cabibbo (pp. 65-71; 84-94) e da Maria Lupi (pp. 72-84; 94-100) si propone di enucleare e presentare i temi più significativi del trattato Espejo católico del mercedario navarrino Ignacio Vidondo, pubblicata a Pamplona nel 1658. Si tratta di un’opera finalizzata a difendere ed esaltare l’attività di riscatto in favore dei "captivi" cristiani in terra musulmana, che rappresentava lo scopo principale dell’ordine della Mercede. Nel volume l’autore porta la sua diretta testimonianza di redentore, narrando la spedizione da lui guidata ad Algeri nel 1654 e analizzando i problemi pratici che comportava il contatto con una società così diversa da quella europea.. ""This essay of Sara Cabibbo (pp. 65-71; 84-94) and Maria Lupi (pp. 72-84; 94-100) introduces and explains the most significant themes of the treatise Espejo católico, published in Pamplona in 1658 and written by Ignacio Vidondo, a Mercedarian born in Navarre. This volume is directed to defend and exalt the ransoming activity of Christian "captivi" in Muslim land, which was the main aim of the Order of Mercy. In his work, the author gives his own account of his activity as redeemer of slaves, describing the expedition he leaded up to Algeri in 1654 and analyzing practical difficulties coming from the contact with a society so different from the european one. .

Ottimizzazione del processo e valutazione dell'adesione di rivestimenti in PCL su lega di magnesio per applicazioni biomediche
No full textLAUREA MAGISTRALEIl rivestimento polimerico di stent biodegradabili in lega di magnesio risulta essere una promettente soluzione per rallentare la velocità di degradazione del metallo e, quindi, garantire il sostegno meccanico alla parete del vaso nei primi mesi dall’impianto. Quantificare l’adesione tra polimero e substrato metallico, inoltre, è essenziale per garantire la sicurezza e l’efficacia del dispositivo a lungo temine. La prima parte del seguente lavoro di tesi è basata sull’ottimizzazione della procedura di dip coating, che ha permesso di realizzare rivestimenti in PCL omogenei e di spessore controllato (5-10 μm) su lastrine in lega di magnesio AZ31 (3% alluminio, 1% zinco e 0,2% manganese), con diversa morfologia superficiale. Per misurare la forza di adesione tra coating e substrato, sono state eseguite prove di peeling a 90°, le quali hanno mostrato come le proprietà del substrato, quali la rugosità e la bagnabilità, influenzino l’adesione del film polimerico.
In seguito, la tecnica del dip coating è stata adattata a campioni aventi la geometria dello stent. Includendo la rotazione del campione durante la fase di ritiro dalla soluzione, è stato possibile realizzare rivestimenti omogenei e aderenti alla maglia. Una volta rivestite di PCL, le maglie metalliche sono state sottoposte a prove di trazione per verificare l’insorgenza di fenomeni di delaminazione del rivestimento. I risultati hanno mostrato un rivestimento continuo ed adeso al substrato, sia nella parte piana, sia nelle zone di curvatura. Leggere zone di distacco del rivestimento si sono riscontrate nelle zone di curvatura più esterne, caratterizzate da un maggior accumulo di materiale polimerico, dovuto all’azione della forza centrifuga durante la fase di rotazione e da una maggiore concentrazione di sforzi.The polymeric coating on biodegradable magnesium alloy stent seems to be a promising solution to reduce the rate of degradation and, thus, to ensure the mechanical support to the wall vessel first months after implantation. To quantify the adhesion between polymer and metal substrate, is essential to ensure the device safety and effectiveness in the long term. The first part of the work was based on the optimization of the dip coating process, which made possible to achieve PCL homogeneous coatings with controlled thickness (5-10 μm) on magnesium alloy AZ31 (3% aluminum, 1% zinc and 0.2% manganese) plates, with different surface morphology. To measure the adhesion strength between coating and substrate, peeling tests at 90° were carried out. Such tests showed that the adhesion of the polymeric film is influenced by roughness and wettability of the substrate.
Subsequently, the dip coating technique was adapted to coat samples characterized by the geometry of the stent. By including the rotation of the sample during the withdrawal phase from the solution, it was possible to achieve coatings uniform and adherent to the mesh. Once coated, the meshes were subjected to tensile tests to verify the occurrence of coating delamination. Results showed a coating continuous and adherent to the substrate, both in the flat part and in the areas of curvature. Weak zones of coating detachment were found in the outer areas of curvature, characterized by an accumulation of polymeric material, caused by the action of the centrifugal force during the rotation and a higher stress concentration
Il conflitto di genere e lo scambio di figura
No full textIn her essay, the author argues that gender conflict cannot be eliminated by eliminating the question of identity, as the American philosopher J. Butler seems to do, but through a strengthening of the idea of relationship. To this end, the author proposes the "exchange" of figures in Plato's Alcibiades I as a strong model of relationship

Nichilismo e amore in attesa del Regno

Roscoe Pound e la concezione teleologica del diritto: tra giuridicità e metagiuridicità
No full textThis paper intends to delve into Roscoe Pound’s thought, enhancing his teleological conception of law as a key to understanding Pound’s historicism, pragmatism and functionalism. The Author will also deal with the Poundian contribution within a ‘situated’ perspective aimed at stressing some ‘genetic’ traits of American legal realism in relation to the specific history of the evolution of the common law in the US context. The text has the objective to discuss the theoretical-legal matrix of Pound’s theoretical reflection and its afference to legal science, highlighting his attitude to address the macro-theme of the constitutive principles of the law itself
