Building in Post-war Environments
No full textModern wars generate devastating effects on the environment by using chemical, biological, radioactive weapons. Toxic effects persist for long time on war fields. Negative environmental impacts such as desertification, migrant masses, depletion of natural resources (food, water, wood, etc.), and induced biodiversity produce, in turn, conflicts.
This paper aims at i) identifying the consequences of conflicts and wars on the built environment with special reference to the industrial and residential buildings in urban areas; ii) determining the environmental impact of the procurement and use of natural resources and materials for the reconstruction of human settlements; iii) describing the results of this contribution according to their practical use. The research starts with a critical analysis of international examples related to modern wars. Contemporary situations of environmental degradation also related to major natural disasters that have altered the context in which they happened have been then analysed. Moreover, results of some significant interventions of environmental clean-up and building reconstruction have been examined, together with guidelines of the international humanitarian organizations on aspects of health and quality of life in areas with depleted environment. Results of these studies permit to suggest a post war methodology for the revitalization of the territory with restocking and monitored rebuilding, coordinated with contextual recovery of ecosystems. Construction techniques, with characteristics of resilience, habitability and sustainability are finally proposed. These solutions must also strive for reintegration of personal property and for the definitive localization of residents respecting their traditions and culture.
Overall, this paper gives an operative contribution to one of the most important problems of humanity, which can be useful to future researches on territories marked by the environmental degradation caused by wars. Recovered environments, made sustainable, may help to understand that the real solution is avoiding wars and their deleterious effects
Multifunctional bioinspired sol-gel coatings for architectural glasses
No full textAlthough several multinational companies have recently released products incorporating bioinspired functional coatings, their practical integration in building envelopes is still an open issue. High production costs associated to the existing vacuum deposition technologies, as well as the difficulties in extending the number of functions achievable by a single coating, represent to date the main limitations to their diffusion on a large scale. This review summarizes the key topics in the field of functional coatings for architectural glasses, focusing in particular on the potential applications of sol-gel based antireflective and self-cleaning coatings, that have received a tremendous attention in the last years. It provides an overview of the recent research efforts aimed to improve their properties and to extend their range of applicability. The bioinspired principles, upon which such coatings are based, are also described and are related to the chemical and morphological properties of such surfaces. (C) 2009 Elsevier Ltd.

Le «buone letture». 2. Giovanni Casati
No full textIl saggio è costituito da due parti, la prima delle quali, dedicata alla fondazione della Federazione italiana delle biblioteche circolanti cattoliche, è stata pubblicata nel precedente numero dei «Nuovi Annali», XXVII (2013), pp. 137-163. In questa seconda parte viene delineata la figura intellettuale di Giovanni Casati, che diresse la «Rivista di letture» dal 1912 al 1944, trasformando il periodico della Federazione in una rivista impegnata nella divulgazione della cultura cattolica. A questo impegno militante Casati fece corrispondere un intenso programma editoriale, che trovò espressione nella pubblicazione di saggi letterari, di manuali e opere repertoriali.The study consists of two parts; the first is dedicated to the history of the Federazione italiana delle biblioteche circolanti cattoliche since its foundation (1904) up to 1912 and was published in the previous volume of the «Nuovi Annali », XXVII (2013), pp. 137-163. In this second part, the author outlines the intellectual figure of Giovanni Casati, who directed the «Rivista di letture» from 1912 to 1944, transforming the magazine of the Federation in a journal engaged in the spreading of Catholic culture. To this militant engagement Casati matched an intense publishing program, which found its expression in the publication of literary essays, manuals and reference works
Comico e tragico del diritto nella novellistica italiana: il novelliere di Giovanni Sercambi
No full textNelle novelle di età tardomedievale ed umanistica, a causa del loro carattere fortemente realistico, il diritto ha un posto importante, poiché rappresenta un elemento centrale e ineliminabile della vita della comunità. Il novelliere di Giovanni Sercambi da Lucca non fa eccezione, anche se l’autore non ha una cultura giuridica né s’interessa in modo specifico al diritto. Il presente saggio vuole analizzare sotto tale profilo queste novelle per verificare quale concezione del diritto emerge da esse e come la narrazione ne risulti arricchita.In the late medieval and humanistic novellas, owing to their very realistic character, the right is an important central and inevitable element in community life. Giovanni Sercambi’s novelliere is no exception even if the author lacks a legal culture, nor is specifically interested in right. This essay intends to analyze these novellas under this profile to verify what kind of right they consider and how the stories are enriched

Scelionidae (Hymenoptera: Platygastroidea) recorded in Italy and their known hosts.
No full textScelionidi (Hymenoptera: Platygastroidea) segnalati per l’Italia e loro ospiti noti.
Il seguente lavoro propone una revisione della checklist italiana della famiglia Scelionidae dopo quella proposta da Bin et al. (1995). Viene inoltre fornito l’elenco delle specie di ospiti di Insecta e Arachnida individuate nel lavoro di raccolta bibliografica. In totale sono riportati 38 generi di scelionidi per l’Italia con 181 specie di cui 58 riportano anche gli ospiti appartenenti
agli ordini: Insecta: Mantodea, Orthoptera, Embioptera, Hemiptera, Coleoptera, Neuroptera, Diptera, Lepidoptera; Arachnida: Araneae Dysderiidae, Lycosidae. Grazie all'intenso lavoro di ricerca del professor Giovanni Mineo, recentemente scomparso, le specie registrate per la Sicilia sono aumentate da 56 a 99. La revisione e l’aggiornamento della checklist nasce dalla recente importanza assunta degli scelionidi nello studio di una possibile loro applicazione
nei programmi di controllo biologico contro eterotteri pentatomidi alloctoni e dall’arrivo in Europa di scelionidi alloctoni come Trissolcus japonicus e T. mitsukurii, candidati per il controllo biologico di Halyomorpha halys.A revised checklist of the Italian Scelionidae is provided. Data regarding host association of recorded species of this family of egg parasitoids of insects and spiders are provided. A total of 181 species in 38 genera have been recorded in Italy. The parasitized hosts are recorded for 58 of recorded species. These species parasitise eggs of different insect orders (Mantodea, Orthoptera, Embioptera, Hemiptera, Coleoptera, Neuroptera, Diptera, Lepidoptera) and spiders (Araneae Dysderiidae, Lycosidae). Scelionidae are considered as effective biological control agents of insect pests, and many times were used in biological control programs. Very recently, two allochthonous scelionids Trissolcus japonicus and T. mitsukurii, candidates of introduction for biological control purposes, accidentally arrived into Europe and Italy and became established, thanks to the presence of their preferred allochthnous host Halyomorpha halys
Chapter Atto biografo di Giovanni Gualberto
No full textThe paper examines the Vita s. Iohannis Gualberti by Atto, reconstructing its genesis and fortune. Probably the author wrote this hagiography when he was abbot and before becoming bishop of Pistoia. He re-elaborated the Life of the saint by Andrea of Strumi, adapting it to a changed historical and ecclesiastical context. The text was successful among the Vallombrosan Order and it was used by later hagiographers to create epitomes and rewritings of the Life of Giovanni Gualberto

IL GRANULOMA CENTRALE A CELLULE GIGANTI DEI MASCELLARI
No full textCentral giant cell granuloma ( CGCG ), is a fibro-osseous lesion. The majority of lesions are observed in the mandible and mainly in children and young adults, more often in females than in males. This lesion, which the pathogenesis still remains obscure, appears as radiolucency, well or ill-defined, uni or multilocular with trabeculations coursing through the lesion. Histologic study shows giant cells, fibroblastic cells, and foci of hemorrhage and osteoid tissue. On the basis of clinical, radiological and histologic features, central giant cell granulomas can be classified as "non-aggressive" or "aggressive"; the histomorphometric analysis prove a significant increase in large giant cells, fractional surface area, and mitotic activity in aggressive CGCG lesions. Immunohistologic investigation (Ki-67 and p53 stain) reveal no significant differences. The patients with aggressive lesions show aggressive growth, pain, massive swelling, root resorption, cortical perforation, and/or recurrence. Clinical and histomorphometric features may be reliable indicators for the differentiation between aggressive and nonaggressive CGCG. This should be accounted for to improve the individual planning of the treatment and follow-up. Alternative treatments are worthy of consideration, although surgical excision remains the treatment of choice
