“Cent’anni di solitudine”? L’architettura dei Chiaromonte tra storiografia e nuove prospettive

2020

Il contributo prende le mosse da una ricognizione storiografica sugli studi dedicati all'architettura del Trecento in Sicilia, evidenziando miti, pregiudizi e assenze che hanno a lungo condizionato i giudizi critici su questa fase della storia della produzione architettonica nell'Isola. Intuizioni, limiti e fraintendimenti di tali letture pregresse sono rimessi in discussione da una riflessione sulle principali residenze dei Chiaromonte, individuando nuove prospettive di ricerca che ribaltino il paradigma dell'isolamento culturale, valutando le possibili relazioni mediterranee di una committenza ambiziosa e che attua anche attraverso l'architettura la propria politica di immagine.

Ritratti di architettura: rappresentazioni e rilievi di edifici del Trecento (XVIII-XIX secolo)

2020

Il contributo presenta alcune fonti iconografiche (un dipinto, incisioni e disegni) appartenenti alle collezioni della Galleria Regionale della Sicilia di Palazzo Abatellis, databili tra XVII e XIX secolo, che ritraggono architetture trecentesche siciliane. Frammento di un vasto patrimonio visuale, che spazia dalle vedute urbane e di paesaggio, al disegno di prospetti ed elementi architettonici, allo studio dei dettagli ornamentali, l'iconografia in esame rientra nel fenomeno delle “riscoperte” dell’architettura medievale siciliana, nel quale si inseriscono anche alcune delle più significative opere trecentesche, direttamente o indirettamente legate all’età dei Chiaromonte.

Experimental observations of upstream overdeepening

2005

The issue of morphodynamic influence in meandering streams is investigated through a series of laboratory experiments on curved and straight flumes. Both qualitative and quantitative observations confirm the suitability of the recent theoretical developments (Zolezzi & Seminara 2001) that indicate the occurrence of two distinct regimes of morphodynamic influence, depending on the value of the width ratio of the channel β. The threshold value βR separating the upstream from the downstream influence regimes coincides with the resonant value discovered by Blondeaux & Seminara (1985). Indeed it is observed that upstream influence may occur only in relatively wide channels, while narrower stream…

BedformMechanics of MaterialsMechanical EngineeringOverdeepeningThe issue of morphodynamic influence in meandering streams is investigated through a series of laboratory experiments on curved and straight flumes. Both qualitative and quantitative observations confirm the suitability of the recent theoretical developments (Zolezzi & Seminara 2001) that indicate the occurrence of two distinct regimes of morphodynamic influence depending on the value of the width ratio of the channel β. The threshold value βR separating the upstream from the downstream influence regimes coincides with the resonant value discovered by Blondeaux & Seminara (1985). Indeed it is observed that upstream influence may occur only in relatively wide channels while narrower streams are dominated by downstream influence. A series of experiments has been carried out in order to check the above theoretical predictions and show for the first time evidence of the occurrence of upstream overdeepening. Two different sets of experiments have been designed where a discontinuity in channel geometry was present such that the channel morphodynamics was influenced in the upstream direction under super-resonant conditions (β >βR) and in the downstream direction under sub-resonant conditions (β <βR). Experimental results give qualitative and quantitative support to the theoretical predictions and allow us to clarify the limits of the linear analysis.MechanicsLinear analysisCondensed Matter PhysicsWidth ratioGeology

Verso una dimensione narrativa delle mappe

2021

Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…

Between the idea and the construction of the architecture the drawing plays a central role to connect the different protagonists of a project. It involves the community by envisaging unprecedented perspectives. Writing is useful to explicit the graphics and establish a new order in the design reasoning. The relationships between signs and meanings multiply in recent information systems in which it seems possible to conclude a lot (thanks to numerical and spatial data) but sometimes a synthesis is missing though that synthesis is fundamental to create new physical experiences. For the exploration of the use of different architectural languages and for the push towards the project rather than a sterile cataloging the case of the Piano Programma for the historic center of Palermo (Giuseppe Samonà Giancarlo De Carlo Umberto Di Cristina Anna Maria Sciarra Borzí 1979-82) reveals to be ambitious. Giuseppe Samonà integrates the classical representation based on Monge's projections with photographs and iconic drawings associating signs with a linguistic-structural communication capable of expressing the relationships between the parts at the basis of a morphological approach to the plan. The graphic story ("second language") of the urban fabric has creative implications expressed by images and annotations ("first language") useful for decoding them. Since the plan focuses on the potential of a storytelling that orients the imagination of its readers (designers citizens politicians) it can contribute to the study titled "B4R– BRANDING 4 RESILIENCE - Tourist infrastructure as a tool to enhance small villages by drawing resilient communities and new open habitats” as a starting point for the mapping in which GIS analysis and multidisciplinary data (geometric topological and quantitative) relating to some villages of the internal Sicily shall translate into a new architectural urban and landscape quality.Settore ICAR/14 - Composizione Architettonica E Urbana

Cappelle di palazzo nella Sicilia del Trecento

2018

Nei palazzi e nei castelli dell’aristocrazia siciliana, realizzati ex-novo o rinnovati nel corso del XIV secolo, la presenza di cappelle palatine appare una costante. Inserite tra gli ambienti della stessa residenza o costruite in volumi autonomi ma adiacenti alla prima, esse contribuiscono a definirne il rango, in un ambiguo equilibrio tra sfera pubblica e privata. Infatti, sebbene destinate essenzialmente a una fruizione privata - della quale tuttavia non si conoscono con precisione modalità e frequenza - si tratta al contempo degli ambienti definiti con maggiore cura e con scelte formali che appaiono mirate a perseguire precise strategie di autorappresentazione, che oscillano tra modelli…

Algunos aspectos de la variabilidad de los oogonios en poblaciones actuales del género &lt;i&gt;Chara&lt;/i&gt; (Charophyceae). Aplicación paleontoló…

1986

A critical revision of some useful taxonomic criteria in paleontology of Charophytes is carried Out. The results are based in four modern populations ((&lt;i&gt;Chara aculeolata, Chara&lt;/i&gt; aff.&lt;i&gt;baltica, Chara delicatula&lt;/i&gt; and &lt;i&gt;Chara globularis&lt;/i&gt;) and they permit to make some serious objections to these critera. The results are related with three principal aspects: the meaning of the absolute magnitudes of me girogonite, the behaviour of his joint variation and the morphological variability during the calcification process. In general, and for each one of the four populations, an absence of influence of the position of the girogonite over their measureme…

Tuning the Magnetic Properties of Carbon by Nitrogen Doping of Its Graphene Domains

2015

Here we present the formation of predominantly sp-coordinate carbon with magnetic- and heteroatom-induced structural defects in a graphene lattice by a stoichiometric dehalogenation of perchlorinated (hetero)aromatic precursors [hexachlorobenzene, CCl (HCB), and pentachloropyridine, NCCl (PCP)] with transition metals such as copper in a combustion synthesis. This route allows the build-up of a carbon lattice by a chemistry free of hydrogen and oxygen compared to other pyrolytic approaches and yields either nitrogen-doped or -undoped graphene domains depending on the precursor. The resulting carbon was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM…

Mens sana in corpore exhausto. Emociones y gestión de sí en escuelas secundarias del sur global

2020

In recent years, emotional education has become a central element in a series of guidelines on a global scale that have been translated into various state initiatives aimed at education. Thus, Mens sana in corpore exhausto proposes to demonstrate the tension that is expressed between the growing series of discourses on emotional education and the school climate and the exhaustive bodies of teachers and directors of public secondary schools in the Metropolitan Region of Buenos Aires (RMBA). By way of hypothesis, these policies are considered to work on the bodies of teachers and directors, encouraging them to continue and not stop under the logic of management and self-management that throw …
