No full textIn Italy there are over 7,000 km of abandoned railways, which constitute a privileged infrastructure for the development of greenways. About 800 km have already been reused, but often the projects have been limited only to the creation of cycle paths of local interest, due to the lack of an overview.
In order to enhance the uniqueness of these routes and promote their attractiveness, the Italian Greenways Association and the Italian Touring Club have created a specific brand called "Binari Verdi", to identify the greenways built along disused rail-ways that have excellent technical and environmental characteristics, thus promoting a new tourism product able to bring im-portant benefits to the territories crossed
Grid based rainfall-runoff GIS modelling to study the anthropogenic effect on the hydrology of a small watershed
No full textIn the Po basin urban development, land use change and variations in rain intensity have influenced watershed runoff and increased floods. In order to better study the anthropogenic effect on the basin hydrology the Olona river watershed proved to be
an interesting small catchment to test. It went through a rapid change from agricultural land to urbanized and partly forest areas over the period 1954 – 1994. The Olona River is known for frequent flooding along its course and in some districts of Milan city. Using SCS-CN methodology, a rainflow-runoff model was calibrated with the observed outflow data in the Ponte Gurone station in the upper Olona basin (≈110 km2 ). The extreme rainfall data series of three meteorological stations near and inside the watershed are statistically elaborated to obtain the depth duration frequency curves, used as the model input data. Basin concentration time and SCS parameter Ia (Initial abstraction) values are chosen to fit the model results and the observed discharges in the two rainfall intensity classes tested. Within the upper Olona basin, waterproof surfaces increase, leading to less infiltration and a quicker runoff, and produce higher outflow peaks. Model results give an estimate of land use change effect on the basin rainfall-runoff process change

Greenways: un modo per valorizzare il patrimonio ferroviario dismesso : una panoramica internazionale

No full textIl tema legato alle Green Infrastructures intese come sistemi verdi efficaci nell’intercettare, accumulare e/o rilasciare gradualmente l’acqua piovana in ambito urbano, andando così a diminuire la portata in ingresso ai sistemi di raccolta e deflusso delle acque meteoriche, è un argomento di grande e crescente interesse a livello internazionale, come dimostrato da numerosi studi scientifici e dalle esperienze dirette sul campo e applicazioni a casi studio, nonché dalla normativa nazionale e locale (tali considerazioni sono state ampiamente approfondite in Appendice 3).
Le infrastrutture verdi sono uno “strumento di comprovata efficacia [...] che ricorre a soluzioni basate sulla natura (Nature Based Solutions - NBS)” (Commissione Europea, 2013), che variano alle diverse scale territoriali: dai singoli alberi lungo le strade, ai tetti verdi e ai giardini privati, fino ai parchi, ai corridoi fluviali e ai boschi.
In tale quadro, il presente documento mira a individuare e descrivere le diverse tipologie di “soluzioni a verde” possibili in ambito urbano, approfondendone i diversi aspetti peculiari. A tale scopo sono state analizzate una vastissima serie di documenti e linee-guida pubblicate da diversi enti (internazionali, nazionali, regionali e locali) in diverse aree del mondo.
L’analisi effettuata ha innanzitutto portato alla selezione dei documenti più completi, aggiornati e rigorosi e, poi, alla verifica della congruità e corrispondenza delle indicazioni ivi riportate, al fine di giungere ad una sintesi verificata.
Il prodotto finale è un documento riportante una serie di “schede” con abaco delle seguenti soluzioni progettuali tipo delle opere a verde: 1. rain gardens, 2. aiuole di bioritenzione, 3. aiuole alberate, 4. laghetti, 5. aree umide, 6. bacini di infiltrazione, 7. canali vegetati, 8. fasce filtro vegetate, 9. trincee filtranti, 10. prati armati, 11. tetti verdi
Albinism and Blood Cell Profile: The Peculiar Case of Asinara Donkeys
No full textThe complete blood cell count (CBC) was screened in a group of 15 donkeys, of which 8 were of Asinara breed (oculocutaneous albinism type 1, OCA1) and 7 of Sardo breed (gray coat). All donkeys were kept under same management and dietary conditions and underwent periodic health monitoring in the month of June 2024, at the peak of the positive photoperiod, at Mediterranean latitudes. One aliquot of whole blood, drawn from each individual into K2-EDTA containing tubes, was analyzed for the complete blood cell count through an automatic analyzer, within two hours of sampling. Data were analyzed and compared by one-way ANOVA, where the breed was an independent variable. All animals appeared clinically healthy, though mild eosinophilia was observed in Sardo donkeys. The red blood cell line showed peculiar traits for Asinara donkeys, which displayed significantly higher circulating red blood cell numbers than gray coat Sardo donkeys (RBC, 5.19 vs. 3.80 1012/mL ± 0.98 pooled-St. Dev, respectively; p = 0.017). RBCs also exhibited a smaller diameter and higher degree of anisocytosis in Asinara donkeys, along with lower hematocrit value, albeit within physiological ranges. Taken all together, such hematological profile depicts a peculiar trait of the red blood cell line in albino donkeys during the positive photoperiod
