ALLOGENEIC BONE GRAFTING MATERIALS – UPDATE OF THE CURRENT SCIENTIFIC STATUS
2017
Worldwide population aging and associated with it epidemics of osteoporosis, widespread of bone and joint reconstructive surgery and first of all joint replacement lead to explosive growth of interest in bone grafting.Although autografts are still the golden standard in bone regeneration, allogeneic bone substitutes have reached a state that allows for their application with satisfying clinical results. However, it has repeatedly been supposed that the different allogeneic materials underwent different purification processes, which modifies bone regeneration properties of these materials and also for different safety conditions. In the present publication, the treatment of the precursor tis…
Les membranes en chirurgie pré-implantaire
2012
The use of membranes in pre-implantation surgery is part of the guided bone regeneration (GBR) concept, one of the usual bone augmentation techniques. Membranes for GBR procedures have two main uses: a mechanical function to maintain bone regeneration space and a physical function as cellular barrier. The goal is to promote colonization of the regeneration space located under the membrane, by osteogenic cells from the residual bone walls. GBR was the subject of numerous publications and protocols since its first use in the 1980s. These protocols are mainly supported by team experience and the level of evidence is poor. Few indications are truly validated. The goal of our study was to review…
Privacy-Preserving Overgrid: Secure Data Collection for the Smart Grid
2020
In this paper, we present a privacy-preserving scheme for Overgrid, a fully distributed peer-to-peer (P2P) architecture designed to automatically control and implement distributed Demand Response (DR) schemes in a community of smart buildings with energy generation and storage capabilities. To monitor the power consumption of the buildings, while respecting the privacy of the users, we extend our previous Overgrid algorithms to provide privacy preserving data aggregation (PP-Overgrid). This new technique combines a distributed data aggregation scheme with the Secure Multi-Party Computation paradigm. First, we use the energy profiles of hundreds of buildings, classifying the amount of &ldquo
Sulle tracce di Ovidio epico? Contese tra padri e figli in Ps. Quint. decl. 258
2018
In the Minor Declamation 258 it is possible to notice some echoes of the Armorum iudicium of Ov. met. xiii 1-383, an episode whose success in Greece and Rome dates back to the Cyclic poems. Porcius Latro, the famous rhetorician and teacher of Ovid, chose this subject for one of his declamations and provided his pupil with a model: in fact, as showed by Sen. contr. ii 2, 8, the poet borrowed from the rhetor some literal expressions. We can also remember Sen. contr. x and Calp. decl. 21, two of the most important texts where the motifs of family disputes and reward for viri fortes are re-elaborated, in different ages. Therefore, the Minor declamation 258 is one of these interesting adaptation…
Polipheries: Heterotopic Cities and Plural Communities of a Different Present in Southern Europe
2018
In Europe, cities have always been theatres that put utopian thinking on the stage. The European city is a “mediation between mediations”, to quote Henri Lefebvre, one of the most lucid philosophers of the city, since the city is a permanent interface for several types of relationships: relationships between individuals, structured and unstructured relationships, and relationships with and between social, institutional, and normative organisations. And in an increasingly urban world where most of the world’s population lives in cities, with levels close to 80% in Europe, cities are the living organisms that breath the breath of change, especially the change in the relationships, visions, an…

La tutela e la gestione delle risorse idriche nella prospettiva del PNRR
2022
The right to accessing clean and drinkable running water for all is formally ensured in Italy, but it is undeniable that there are substantial distribution and pollution problems that hinder its fulfilment. That is especially true for southern and insular areas where the living conditions for large parts of the population remain problematic. The European Court of Justice has condemned Italy twice already for these deficiencies, which are now aggravated as a result of the health and economic crisis linked to Covid-19 pandemic. Accordingly, there is a pressing need for a serious and systematic intervention of the legislator, leading to the renewal of legislation on national and regional level…

Modulation of surface plasmon coupling-in by one-dimensional surface corrugation
2008
Surface plasmon-polaritons have recently attracted renewed interest in the scientific community for their potential in sub-wavelength optics, light generation and non-destructive sensing. Given that they cannot be directly excited by freely propagating light due to their intrinsical binding to the metal surface, the light-plasmon coupling efficiency becomes of crucial importance for the success of any plasmonic device. Here we present a comprehensive study on the modulation (enhancement or suppression) of such coupling efficiency by means of one-dimensional surface corrugation. Our approach is based on simple wave interference and enables us to make quantitative predictions which have been …
