La chiesa di San Giovanni del Toro a Ravello
No full textLa storia millenaria di San Giovanni del Toro ripercorsa dalla fondazione agli ultimi restauri in un volume a più mani. Giuliana Capriolo analizza l’atto del 1018, con cui cittadini ravellesi stabilirono la nascita della chiesa, mentre Giuseppe Gargano illustra il contesto sociale, culturale ed economico della città nei secoli del basso medioevo. Antonio Milone approfondisce l’arte e l’architettura dell’edificio, dall’impianto originario a tre navate alla realizzazione del transetto cupolato e della cripta. Il riuso e la rilavorazione dei materiali antichi, l’esecuzione dell’arredo liturgico interno, con il pulpito e i resti dell’altare, l’ampliamento degli spazi per ospitare cappelle e monumenti funerari per le famiglie cittadine, che ne curarono la decorazione, sono alcuni dei temi affrontati, unitamente ai danni e alle modifiche all’architettura e all’arredo in età moderna, al depauperamento del patrimonio artistico e alle soluzioni adottate nei restauri degli ultimi decenni. Conclude il volume una riflessione di Enrico dal Covolo che confronta la figura dei due Giovanni: il Battista e l’Evangelista

La pro Milone dopo la pro Milone
No full textPer quanto destinata a soccombere sotto un plateale insuccesso, l’orazione pro Milone di Cicerone gode di una straordinaria fortuna nella tradizione seriore. Il contributo puntualizza le ragioni e le tappe di tale successo ‘a posteriori’, conferendo una particolare importanza all’opera di Quintiliano. Nella Institutio oratoria, infatti, si assiste ad una copiosa messe di citazioni del testo ciceroniano; esse, peraltro, appaiono tutte adoperate in contesti di particolare rilievo, ove il retore di età flavia si trovi a commentare la necessità di certi cambi di strategia argomentativa o, ancora, la proficuità di un uso multiplo della dottrina degli status, di cui Cicerone dà prova nella tractatio extra causam, che occupa i pp. 72-91 dell’orazione. La ricezione del testo viene poi seguita nelle opere di alcuni retori tardi, che pongono particolare attenzione ad aspetti di volta in volta differenti ma che costituiscono delle vere emergenze testuali, quali, tra tutti, il sapiente impiego ciceroniano della evidentia nella ricostruzione del momento dello scontro tra le due bande armate lungo la via Appia. A conferma poi della fortuna di lungo corso di cui godette l’orazione si cita il riuso che ne fece nel processo del cosiddetto massacro di Boston John Adams, giovane e brillante avvocato, futuro secondo presidente dei nuovi Stati Uniti d’America, ma, soprattutto, come si dimostra dalla lettura delle sue memorie, entusiasta lettore di Cicerone e della pro Milone in particolare
Assessment of the renewable energy production in a historical building for a touristic intended use: a technical-economic feasibility study
No full textThis column deals about a study based on technical and economical feasibility of a combination of technologies and systems for energy production concerning electric, heating and cooling to install on a building in the historic centre of a Sicilian city (Italy). After a functional review and an energetic evaluation, the building will have a hotel destination.
A first evaluation, made on a model set with the geometrical, thermo-physical and climatic data both of the building and the place, allowed to make a dynamic simulation to define the energetic monthly needs. The evaluation has been done considering different solutions and technologies.
With the collected data we supposed a first sizing of the HVAC systems used for the next
economical evaluation. We considered the expenses for realization and the energy saved using methods called “Actualized net value” and “Payback Time”. The final analysis shows benefits and disadvantages on each simulations with every kind of technologies used helping us to decide what to use
Solar cooling: study on the technical-economic feasibility of a plant in a hotel.
No full textSolar air conditioning allows more energy savings than air conventional
conditioning plants. Just like the thermal solar systems for heat production destined
to large consumers, solar air conditioning represents a technology that turns out to
be economically more favorable. Its employment for the summer air conditioning of
buildings represents today an ulterior and very interesting field of application. This
article shows the results of a study on the technical-economic feasibility of a solar
cooling plant realized in a hotel in South Italy. Just like the air conditioning load
produced by electric power, hot water produced by thermal solar plants has a
periodic character which, in both cases, is higher in the summer period. The
coincidence on a yearly base of these two factors makes solar cooling particularly
interesting both from the environmental and economic point of view, involving a
possible future and natural drop of the plant set-up costs. Greater accessibility to the
available technical opportunities and, above all, to the incentives for the necessary
investments could accelerate the development of this remarkably interesting
technology

Thirteen facts that you need to know on multiple populations in globular clusters
No full textI review the methods, mostly developed in the last decade, that are commonly used to identify and characterize multiple populations (MPs) in Globular Clusters (GCs) based on photometry. I summarize the results from the recent surveys of MPs with the Hubble Space Telescope (HST) and ground-based facilities and provide a list of the main properties of MPs as inferred from these studies
A Simulation of daylight levels for the determination of visual comfort in large spaces
No full textIn sizable environments, such as the collective areas
of a big university building, characterised by very
long corridors, large hallways and broad glazed
surfaces, the daytime illumination factor is often only
excellent near to the latter, due to their
predominantly horizontal, rather than vertical, nature.
His study, which has been carried out thanks to a
simulation software, shows the results of a
correlation between light contributions, come out
from the wide glass surface and those of a big
skylight which cross lenghtways the main part of the
building.
Such results have been compared with some
instrumental measurements considering the shifting
and getting from them important informations on
simulations reliability
A Simplified Approach for the Corrosion Fatigue Assessment of Steel Structures in Aggressive Environments
No full text: Fatigue performance is often a key aspect when dealing with existing steel structures such as steel bridges or offshore constructions. This issue proves to be more critical as these structures are usually located in aggressive environments and are thus exposed to progressive degradation. Indeed, disruptive phenomena such as corrosion can severely worsen the fatigue performance of the steel components. Currently, the normative standards do not provide a codified procedure for the fatigue checks of steel structures subjected to ongoing corrosion. Within this framework, in this paper a simplified approach for the life-cycle assessment of corroded steel structures is proposed. For this purpose, the concept of "critical corrosion degree" is introduced, allowing the expression of corrosion fatigue checks in a more direct "demand vs. capacity" form with respect to the currently available methods. A first validation of such methodology is reported for the corrosion fatigue tests drawn from the literature. The predicted levels of critical corrosion are in good agreement with the values of artificially induced corrosion (i.e., 4, 8, and 12% of mass loss, respectively), with a maximum relative error of ≈9.3% for the most corroded specimen. Finally, parametrical analyses are performed, highlighting the influence of the model parameters on the corrosion fatigue performance of the steel elements
