Ipotesi di ricostruzione virtuale della piazza maggiore a Noto Antica
2019
Today ancient Noto is a medieval archaeological site, yet to be discovered. After the 1693 earthquake, the ancient city of Noto, in the middle of the Baroque period, was rebuilt in another place and the ancient city was abandoned. The first excavation campaign in ancient Noto by Paolo Orsi dates back to the period between 1894 and 1896. In the following years there will be other excavation campaigns, in which other architectural and sculptural relics will be found. They are today part of the collection of the Civic Museum. The contribution focuses on the study of the piazza Maggiore (Main Square) site, the center of the ancient city and on the surrounding buildings. After analyzing the limi…
Frammenti urbani resilienti. Conservazione e valorizzazione del Teatro greco romano e dell'Odèon di Catania
2019
Il contributo ripercorre le fasi di ricerca finalizzate allo studio del Teatro greco romano e dell'Odèon di Catania, alla caratterizzazione della forme di degradazione delle testimonianze archeologiche ed alla definizione di un progetto di conservazione integrata da nuovi innesti architettonici e da un programma di rifunzionalizzazione dell'intero complesso. The contribution traces the research phases aimed at the study of the Greek-Roman Theater and the Odèon of Catania, at the characterization of the forms of degradation of the archaeological remains, and at the definition of a conservation project integrated by new architectures and by a re-functionalization program of the whole complex.
Modern Impressionist or Idyllic Genre Painter? Zorn’s European Fame from an Italian Perspective
2013
This article examines Zorn's international fame (France, Germany) and then focuses on the Swedish painter's controversial reception in Italian media (Vittorio Pica, Ardengo Soffici).
Fractional-order constitutive equations in mechanics and thermodynamics
2019
This chapter is devoted to the application of fractional calculus in mechanics of materials and thermodynamics. The use of fractional calculus in mechanics is related to the definition of fractional-order constitutive equations leading to the class of fractional hereditariness. In this regard, a brief description of the classical rheological models of material hereditariness and a comparison with the fractional elements are reported. It is shown that a rheological hierarchy corresponding to the fractional order stress-strain relation may be defined. Such a model provides a multi-scale mechanical picture of the power-law hereditariness and it leads toward an unique definition of material fre…
TAP off - tumors on
1997
Abstract The molecular characterization of T-cell-defined tumor-associated antigens has provided targets for cell-mediated immunotherapy for malignant diseases. The success of this strategy is negatively influenced by structural and functional abnormalities of major histocompatibility complex (MHC) class I molecules, which provide tumor cells with resistance to T-cell-mediated immune recognition. This article reviews the physiology of the MHC class I processing machinery and describes the deficiencies of this pathway in malignant cells.
The enemy in you: the interdependency of the localisation and antigenicity of proteins
2009
The subcellular localisation of protein components should be important for their antigenicity. This assumption is derived from the concept of MHC restriction, where CD4 and CD8 T lymphocytes can only interact with MHC II and MHC I surface receptors, respectively. If this mechanism applies, however, then intracellular components should have immunogenic effects mediated by MHC II and CD4 T lymphocytes as soon as they enter the extracellular space. Conversely, extracellular components should generate an immune response that is mediated by MHC I and CD8 lymphocytes when they breach the intracellular space and when they exceed a critical concentration. In this study, these hypotheses were invest…
Stimulation of human T cells by microbial 'superantigens'.
1991
The enterotoxins and the TSST of S. aureus, the erythrogenic toxins A and C of S. pyogenes and a still uncharacterized exoprotein of M. arthritidis belong to a family of exotoxins that have in common a potent mitogenic activity for T lymphocytes of several species. These proteins stimulate CD4+ and C8+ T cells, as well as a fraction of gamma delta TCR-bearing T cells by cross-linking variable parts of the T cell antigen receptor with MHC class II molecules on accessory or target cells. They are functionally bivalent molecules having distinct interaction sites for variable parts of the TCR and for nonpolymorphic parts of the MHC class II molecule. For alpha beta TCR-bearing T cells the V bet…
Un testigo del arte barroco "novator" valenciano de "La Vall de Gallinera": la iglesia parroquial de San Miguel de Benissivà
2002
El estudio nos presenta una muestra de recuperación de artesanías tradicionales en el medio rural como proyecto de enseñanza-aprendizaje de la Universitat de València y su Área de Conservació del Patrimoni Cultural, desde unos análisis histórico-material, histórico-artístico y técnico, en torno a la intervención llevada a cabo en la iglesia de San Miguel de Benissivà de Alicante. Buscando su valoración dentro del conjunto patrimonial al cual pertenece, se acomete una investigación sobre dicho templo y sus transformaciones, sus orígenes, evolución y creadores (entendidos dentro de la etapa artística valenciana de esplendor barroco y clasicismo matemático en la que se encuentran inmiscuidos),…
The stakeholder's perception of socio-economic impacts generated by COVID-19 pandemic within the Italian aquaculture systems.
2021
From the beginning of March 2020 and for the following two and half months, many European countries comprising Italy have been forced into an unprecedented lockdown, allowing only the opening of essential economic activities needed to address the problems created by the pandemic (e.g. sanitary, food provision). Like many sectors of the Italian economy, aquaculture has also slowed down due to the ongoing emergency and the consequent closure of business. In our study we provided a ‘snapshot’ of the socio-economic effects of the lockdown on the aquaculture sector in Italy, immediately following the adoption of the COVID-19 restrictions as they were perceived by the workers. Although it was sur…
Pietro Lojacono : restauri in Calabria e Sicilia
2022
The essay investigates the complex personality of the engineer Pietro Lojacono (Palermo 1900 - Rome 1972), who di- stinguished himself throughout his life in the field of conservation of the architectural and landscape heritage, not only in Italy, but also abroad and in particular on the island of Rhodes, in Greece . Lojacono was a man fully inserted into the cultural debate on the Restoration of monuments, able to testify to the principles acquired, but also to suggest new instances, such as maintaining authenticity, against the continuous replacement of degraded stones, up to the complete replacement of the material of the monuments. Among the many researches and restoration interventions…
