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

Considerations for the Analysis of Small Extracellular Vesicles in Physical Exercise

2020

Physical exercise induces acute physiological changes leading to enhanced tissue cross-talk and a liberation of extracellular vesicles (EVs) into the circulation. EVs are cell-derived membranous entities which carry bioactive material, such as proteins and RNA species, and are important mediators of cell-cell-communication. Different types of physical exercise interventions trigger the release of diverse EV subpopulations, which are hypothesized to be involved in physiological adaptation processes leading to health benefits and longevity. Large EVs (“microvesicles” and “microparticles”) are studied frequently in the context of physical exercise using straight forward flow cytometry approach…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy

2015

ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.

Three Phages from a Boreal Lake during Ice Cover Infecting Xylophilus, Caulobacter, and Polaromonas Species

2023

Although the important role of microbes in freshwater is well understood, studies on phage–host systems in such environments during ice cover are completely lacking. Here, we describe the isolation and characterization of three new bacteriophages infecting Xylophilus sp., Caudobacter sp., and Polaromonas sp. from freshwater samples taken under the ice cover of Lake Konnevesi, Finland. Lumi, Kuura, and Tiera bacteriophages have tailed icosahedral virions and double-stranded DNA. Lumi is a siphophage with a genome of 80,496 bp, and Kuura and Tiera are podophages, and their genomes are 43,205 and 45,327 bp in length, resembling viruses in the class Caudoviricetes. Their host ranges were very l…

On the Dynamics of Fractional Visco-Elastic Beams

2012

With increasing advanced manufacturing process, visco-elastic materials are very attractive for mitigation of vibrations, provided that you may have advanced studies for capturing the realistic behavior of such materials. Experimental verification of the visco-elastic behavior is limited to some well-known low order models as the Maxwell or Kelvin models. However, both models are not sufficient to model the visco-elastic behavior of real materials, since only the Maxwell type can capture the relaxation tests and the Kelvin the creep tests, respectively. Very recently, it has been stressed that the most suitable model for capturing the visco-elastic behavior is the spring-pot, characterized …

Singing is what we do (together) - redefining "together" : A comparative study

2021

This article discusses the impact that the Covid-19 pandemic has had on singing with children in schools by providing a descriptive analysis of a comparative look at children's experiences of their singing habits and emotional well-being during the first Covid-19 lockdown. Covid-19 has established itself as (for now) an ever-present variable in our daily lives. This paper offers a descriptive analysis of a comparative study of the Covid-19 lockdown(s) influence on children's singing habits and emotional well-being in Italy, Austria, and Finland. A survey was carried out on children and young people aged 10-20 from Austria, Finland, and Italy on how the Coronavirus lockdown has impacted thei…
