Evidence for shifts in the structure and abundance of the microbial community in a long-term PCB-contaminated soil under bioremediation.
2011
International audience; Although the impact of bioremediation of PCB-contaminated sites on the indigenous microbial community is a key question for soil restoration, it remains poorly understood. Therefore, a small-scale bioremediation assay made of (a) a biostimulation treatment with carvone, soya lecithin and xylose and (b) two bioaugmentation treatments, one with a TSZ7 mixed culture and another with a Rhodococcus sp. Z6 pure strain was set up. Changes in the structure of the global soil microbial community and in the abundances of different taxonomic phyla were monitored using ribosomal intergenic spacer analysis (RISA) and real-time PCR. After an 18-month treatment, the structure of th…
Blind deconvolution using TV regularization and Bregman iteration
2005
In this paper we formulate a new time dependent model for blind deconvolution based on a constrained variational model that uses the sum of the total variation norms of the signal and the kernel as a regularizing functional. We incorporate mass conservation and the nonnegativity of the kernel and the signal as additional constraints. We apply the idea of Bregman iterative regularization, first used for image restoration by Osher and colleagues [S.J. Osher, M. Burger, D. Goldfarb, J.J. Xu, and W. Yin, An iterated regularization method for total variation based on image restoration, UCLA CAM Report, 04-13, (2004)]. to recover finer scales. We also present an analytical study of the model disc…
Una pequeña lámina de plomo con inscripción ibérica de paleografía arcaica del Pico de los Ajos (Yátova, València)
2021
espanolEn este trabajo editamos una pequena lamina de plomo hallada en el Pico de los Ajos (Yatova) en la campana de 2018. La lamina aparecio plegada y contiene una inscripcion iberica de una sola linea en cada cara que muy probablemente configure un solo texto completo. Sus caracteristicas formales son poco comunes, siendo el paralelo mas cercano el de las laminas votivas de El Amarejo. La presencia del elemento kutuŕ, frecuente en las inscripciones votivas rupestres, tambien apuntaria a una interpretacion religiosa. Desde el punto de vista paleografico, cabe senalar que se trata de un texto explicitamente dual, ya que conviven en el las dos variantes de te y ŕ. A pesar de que el contexto …
Aspetti tecnologici per il riuso: contributi al dibattito
2016
Qui il taglio della trattazione sul riuso della Centrale Enel Tifeo è legato alle questioni tecnologiche sia pure in un’accezione ampia che declina sia le tecniche ambientali che le tecnologie connesse agli edifici e alle costruzioni. Una lettura disciplinare, certamente parziale e limitata, che non vuole mancare però di individuare fattori comuni e temi di dibattito di più ampio respiro. Si tenta questa analisi con una struttura di tre paragrafi, parzialmente correlati a scale di problemi: il contesto e il lotto, quale area di dominio; l’involucro, soprattutto considerato per l’edificio dei turbo-alternatori; l’ambiente indoor e gli spazi interni in edifici dalla spazialità estremamente pa…
REHABILITATION, ENHANCEMENT AND PROMOTION OF ART NOUVEAU BUILDINGS
2016
Since ancient times every era has produced a particular architectural heritage with different materials and with the use of different construction. This study aims to make a contribution in terms of knowledge and the architectural heritage of the 20th century, recovery, and in particular those representing the Sicilian architecture known as Liberty architecture. The study explores the relationship between architecture, materials, construction techniques and the building restoration and enhancement problems. The main purpose of this research is on the one hand the analysis and technological knowledge of the architectural heritage and the other to study the types of …
Camillo Boito e la sua precoce teorizzazione del restauro architettonico
2017
Camillo Boito è stato considerato, a partire dal primo Novecento, come «ispiratore della moderna teoria del restauro» o come «ideatore della concezione intermedia tra le posizioni di Viollet-le-Duc e Ruskin». Il contributo intende fornire nuovi elementi per inquadrare più nitidamente il reale apporto di Boito alla definizione del restauro come disciplina. From the beginning of the XX century, Camillo Boito was considered the "inspirer of the modern restoration theory" or the "creator of the intermediate position between the ones of Viollet-le-Duc and John Ruskin". This contribution aims to provide new elements to frame Boito's real contribution to the definition of restoration as a discipli…
Anamnesi di un’architettura del Novecento, manifestazioni patologiche e tecniche per il risanamento: il caso dello Stand Florio a Palermo
2010
Il poster mostra l'anamnesi di un architettura del XX secolo, ed evidenzia le manifestazioni patologiche e le tecniche per il suo restauro conservativo. The poster shows the case history of a twentieth century architecture, and underlines the pathological manifestations and techniques for its restoration.
Il tema delle absidi nelle Cattedrali normanne di Palermo e Cefalù tra storia, storiografia e restauri
2021
The essay illustrates the main characteristics of the Norman apses of the Cathedrals of Palermo and Cefalù, with specific reference to the themes of the cleristory (or internal gallery or ambulatory) and the relative connections at height . These areas, in Sicilian architecture in which Arab, Byzantine and Norman characters are hybridized in a splendid mix, have been the subject of a rich Sicilian historiographical production, which is accounted for. The interpretation of history and of the transformations that have affected complexes of such high value, experienced through documents and critical reasoning on the reliefs with the hypothesis of restitution, allows us to make a contribution t…
Condition and Role of the Norman Cathedrals in the Fourteenth Century: Maintenance, Restoration and Renovation
2022
After conquering Sicily between 1061 and 1091, the Normans built new cathedrals that modified not only religious life, but also architecture and urban layout. Dramatic events, like wars, earthquakes, and fires, clumsy restorations and culpable inaccuracy have profoundly altered the appearance of Norman cathedrals. The aim of this paper is to analyse the state of conservation of the Cathedrals of Palermo, Monreale, Messina and Agrigento in the fourteenth century, when Sicily was profoundly affected by the war between the Angevins and the Aragonese that lasted ninety years and impoverished the island. The analysis of four case studies from the past will allow us to outline new perspectives fo…
Piano col colore! Mezzo secolo di contraffazioni nei centri storici
2010
The transformation dynamics of the ancient towns are completely changing the urban landscape of the historical countries in Italy in the last fifty years. The most superficial part of material constitutes the image of the architectures and plays a meaningful role in the perception of the historical districts that still characterize the contemporary city, but the aptitude for destroying architectural finishes and deleting superficial patina involves therefore to alter the character of the old towns irreversibly. It had to be obvious it would have been essential to conserve the authentic materials and signs of time that denote the historical authenticity of monuments, but new surfaces of plas…
