Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia

2018

The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…

tale percentuale se considerata per i comuni costieri supera il 75% del territorio urbanizzato. Nel caso dei sistemi naturali i fenomeni di pressione umana pesano su una situazione già critica data da una distribuzione puntuale delle aree protette. Il livello di frammentazione e isolamento di queste aree rischia di peggiorare. In Sicilia l'assenza di strumenti di valutazione ambientale e lo scollamento tra pianificazione urbana e regionale e pianificazione settoriale hanno determinato un inadeguato livello di controllo della pressione umana sui sistemi ambientali. Riguardo a questo quadro generale il presente documento presenta un chiarimento e una riformulazione del rapporto di reciprocità tra ambiente edificato e territorio aperto con l'obiettivo di individuare possibili strategie per gestire i fenomeni di dispersione urbana nel contesto metropolitano obiettivo principale delle politiche territoriali europee e di molte politiche nazionali degli Stati membri.Settore ICAR/20 - Tecnica E Pianificazione UrbanisticaIl consumo del suolo a causa dell'urbanizzazione è un fenomeno già da molti anni sotto osservazione ma di cui solo l'ambiente scientifico ha notato l'elevato impatto ambientale. Da un punto di vista disciplinare è possibile individuare una linea di ricerca incentrata sull'analisi e l'identificazione di nuove morfologie dell'urbanizzazione e sull'interazione tra i diversi modelli insediativi che coesistono in un contesto specifico. Questa lettura si integra con la produzione scientifica sulle forme di pressione insediativa sui sistemi ambientali producendo cambiamento e deterioramento degli ecosistemi naturali e perdita di biodiversità. Un riferimento necessario per questa linea sono gli studi sui processi di frammentazione (lineare concentrato misto) e quelli sulla segregazione degli habitat naturali e seminaturali (protetti o non protetti). Tali riferimenti si combinano con le analisi condotte sul processo di sostituzione dei sistemi naturali con l'ecomosaico artificiale. Lo stato dell'urbanizzazione in Sicilia è interessato dal fenomeno della dispersione urbana che a partire dagli anni Settanta ha contribuito fortemente a plasmare il territorio regionale sia dal punto di vista fisico che funzionale. Tale fenomeno ha interessato principalmente le aree marginali intorno alle aree metropolitane dove i terreni consumati dagli insediamenti a bassa densità abitativa rappresentano il 42% dell'intero territorio urbanizzatoSettore ICAR/21 - Urbanistica

Gill area explains deviations from body size–metabolic rate relationship in teleost fishes

2022

Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted from FishBase. They explore whether species deviations from metabolic rates predicted by body mass can be explained by species gill area. They show that the gill area explains c. 26%–28% of species-level deviations from mass-specific metabolic rates. Their findings suggest that gill area might indeed be one of the factors limiting metabolic rate in fishes.

E-Sports y brecha de género: la percepción de las profesionales españolas

2019

The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…

Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile

2019

1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2.

Objectives pursued and achieved Conjectural reconstruction achieved the following results: • formulation of analytical documents which show how the planimetric and altimetric articulation are perfectly consistent with the functional program• definition of the level of uncertainty1. Brief description of the object of study The competition of the Palace of Justice in Rome takes place in four phases between 1884 and 1887. The project for the first competition in 1884 drawn up by the then very young Ernesto Basile (Palermo 1857-1932) reveals a great deal of design expertise that transforms the complex functional program into an austere building in neo-florentine style. The original drawings of the building not realized kept in the Basile Endowment of the Department of Architecture of the University of Palermo have been the subject of preliminary study to the phases of analysis interpretation and conceptual reconstruction of the digital model. 2. State of the art and main bibliographical references The conjectural reconstruction on the basis of drawings and archival documents is a well-established and codified practice thanks to various disciplinary contributions at national and international level.

Laser fluence, repetition rate and pulse duration effects on paint ablation

2006

Abstract The efficiency (mm3/(J pulse)) of laser ablation of paint was investigated with nanosecond pulsed Nd:YAG lasers (λ = 532 nm) as a function of the following laser beam parameters: pulse repetition rate (1–10,000 Hz), laser fluence (0.1–5 J/cm2) and pulse duration (5 ns and 100 ns). In our study, the best ablation efficiency (η ≅ 0.3 mm3/J) was obtained with the highest repetition rate (10 kHz) at the fluence F = 1.5 J/cm2. This ablation efficiency can be associated with heat accumulation at high repetition rate, which leads to the ablation threshold decrease. Despite the low thermal diffusivity and the low optical absorption of the paint (thermal confinement regime), the ablation th…

The (im)possible success of disadvantaged students. Reflections on education, migration and social change

2019

The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…

Cuerpos de energía: Formas alternativas de ser-en-el-mundo

2020

Based on an ethnographic approach, this paper explores how members of a new age spiritual movement known as ?Llave Mariana? (LLM) build and experience their bodies. At the same time, it develops a thick description of their ritual practices and later it analyzes, delving fundamentally into the phenomenological perspective, how these members shape and transform their forms of self-perception, experience, and representation of others and the environment. Finally, it considers the implications these spiritual practices have in the search and consolidation of alternative ways of being-in-the-world
