Estudio descriptivo y experimental del bloqueo del nervio tibial. Eficacia anestésica de la técnica retromaleolar y supramaleolar.
2018
INTRODUCCIÓN De los cinco troncos nerviosos que inervan el pie, el nervio tibial es el que presenta mayor dificultad para su bloqueo anestésico. Esta dificultad intrínseca del bloqueo selectivo del nervio tibial, está íntimamente relacionada con la localización del tronco nervioso en un plano más profundo, asociada a las características morfológicas del pie. A estos dos factores se les debe sumar el hecho de que el nervio tibial se ramifica distalmente en el nervio calcáneo, el nervio plantar interno y el nervio plantar externo. El interés especial por alcanzar un bloqueo efectivo del nervio tibial se debe a que el territorio que inerva este nervio se ve comprometido tanto en el caso de cir…

(Ri)tradurre Keats: il prestito della lingua
2017
Ricognizione sui rapporti fra traduzione e canone attraverso la nuova traduzione di John Keats. Keats può dirsi propriamente romantico? Quale lingua per la nuova traduzione? Quali i principali problemi da affrontare? Con riferimento agli studi di Apel e Venuti, l'articolo riflette su questioni fondamentali della prassi traduttologica e della storiografia letteraria.
Toward Quaternary QCA : Novel Majority and XOR Fuzzy Gates
2022
As an emerging nanotechnology, quantum-dot cellular automata (QCA) has been considered an alternative to CMOS technology that suffers from problems such as leakage current. Moreover, QCA is suitable for multi-valued logic due to the simplicity of implementing fuzzy logic in a way much easier than CMOS technology. In this paper, a quaternary cell is proposed with two isolated layers because of requiring three particles to design this quaternary cell. Moreover, due to the instability of the basic gates, the three particles cannot be placed in one layer. The first layer of the proposed two-layer cell includes a ternary cell and the second one includes a binary cell. It is assumed that the over…

Preparazione e caratterizzazione di nanocompositi strutturali costituiti da poliammide e carbonio nanostrutturato
2014
L’obiettivo della presente tesi di dottorato è stato la preparazione e la caratterizzazione di nanocompositi a matrice polimerica contenenti forme allotropiche del carbonio nanostrutturato; tali materiali, grazie alle particolari caratteristiche meccaniche e di rinforzo, trovano applicazione nella fabbricazione di speciali dispositivi individuali come guanti, elmetti, corpetti, etc... Sono state preparate fibre di poliammide (PA) contenenti carbon black (CB), nanoplacchette di grafite (GNP) e nanotubi di carbonio (CNT); per questi ultimi sono stati valutati, inoltre, gli effetti delle loro dimensioni e della funzionalizzazione della loro superficie sulle proprietà di rinforzo dei nanocompos…
Risk narrations and perceptions in the COVID-19 time. A discourse analysis through the Italian press
2020
This paper explores how the risk related to the pandemic of COVID-19 was managed, narrated and perceived in Italy during the lockdown phase, from February until June 2020. To reach this aim, the study provides a discourse analysis of three main level: the official institutional discourses declaimed by the government and the health authority; the risk narration spread through the diaphragm of the Italian press, and specifically through two of the most-read newspapers in Italy (Repubblica and Corriere della Sera) and their related weeklies (Venerdì di Repubblica and Sette); finally, the diverse reactions and perceptions to the risk coming from the most affected and most vulnerable subjects, c…

La discussione ortografica tedesca a metà del Novecento: le Stuttgarter e Wiesbadener Empfehlungen.
2008
The twentieth century has been for the German orthography a period of several studies and discussions which gave scientific foundation to the 1996 spelling reform. There were plenty of public and private initiatives which, by involving an constantly increasing number of writers into the debates, tried to simplify the spelling to a more rational regulation. This essay focuses on the discussion in the late Fifties and especially on two reform projects: the Stuttgarter (1954) and the Wiesbadener Empfehlungen (1958). Despite their deeply different historical background from that of the recent successful reform, these projects are of fundamental interest for contemporary studies, since they give…
Hetero-difunctional dimers as building blocks for the synthesis of poly(amidoamine)s with hetero-difunctional chain terminals and their derivatives
2012
This article reports on a simple and straightforward preparation method of poly(amidoamine)s (PAAs) with hetero-difunctional chain ends as well as of several up to now hardly obtainable PAA derivatives of biotechnological interest, such as for instance PAAs of controlled molecular weight and narrow polydispersity mono-functionalized at one end with an acrylamide group, PAAs with star-like molecular architecture, graft-PAA-protein conjugates, “tadpole-like” PAA conjugates with hydrophobic moieties able to self assemble into nanoparticles in aqueous media. The key step was to design suitable building blocks consisting of hetero-difunctional dimers (HDDs). In particular, the HDDs considered we…
