La formazione per il paesaggio tra percorsi di ricerca e applicazioni progettuali
2009
L’esperienza della Regione Siciliana nell’ambito della pianificazione paesistica si sta confrontando in questi anni con la dimensione della redazione dei piani di ambito. Il tema nodale del passaggio di scala tra la dimensione regionale, con riferimento alla legislazione di settore, e il progetto di paesaggio a livello locale, su unità territoriali connotate e configurate da caratteri individuali e riconoscibili, trova risposte nella pratica disciplinare con l’applicazione alle singole specificità dei luoghi. L’esperienza della redazione del piano d’ambito n. 5, “Area dei rilievi dei monti Sicani”, fornisce al livello di piano di dettaglio spunti di innovatività per verificare definizioni, …

La Casa del Popolo di Palermo: l'ennesimo caso di inerzia politica e amministrativa. Ipotesi di uso dei beni comuni per una buona discussione
2020
L’articolo tratta di un caso studio relativo allo sgombero della Casa del Popolo, avvenuto a Palermo nel settembre del 2019 ed all’avvio di una azione giudiziaria a carico di ventidue attivisti. Il processo non è ancora iniziato. Agli imputati, nel mese di novembre 2019, è stato notificato l’avviso di conclusione delle indagini, con il quale è stato contestato loro il reato di concorso in invasione di terreni ed edifici pubblici o destinati ad uso pubblico (artt. 110, 633 e 639 bis c.p.), senza alcuna distinzione tra i soggetti «occupanti» e soggetti che frequentavano il luogo solo per partecipare ad iniziative di carattere culturale. Attraverso un’analisi del caso e dei fatti che lo caratt…
Study of the response of phenol compounds exposed to gamma photons and neutrons for Electron Spin Resonance dosimetry

Humidity-enhanced sub-ppm sensitivity to ammonia of covalently functionalized single-wall carbon nanotube bundle layers
2017
International audience; A low-cost method for carbon nanotubes (CNTs) network production from solutions on flexible polyethylene naphthalate substrates has been adopted to prepare high quality and well characterized SWCNT bundle layers to be used as the active layer in chemiresistor gas sensors. Two types of SWCNTs have been tested: pristine SWCNTs, deposited from a surfactant solution, and covalently functionalized SWCNTs, deposited from a dimethyl-acetamide solution. The humidity effects on the sensitivity of the SWCNTs network to NH3 have been investigated. The results show that relative humidity favors the response to NH3, confirming recent theoretical predictions. The COOH-functionaliz…
Preliminary magnetic resonance relaxometric analysis of Fricke gel dosimeters produced with polyvinyl alcohol and glutaraldehyde
2017
This work describes the preliminary analysis of Fricke gels dosimeters characterized by a new formulation making use of a matrix of polyvinyl alcohol cross-linked by adding glutaraldehyde and analyzed by means of nuclear magnetic resonance relaxometry. In previous optical studies, these gels have shown promising dosimetric features in terms of photon sensitivity and low diffusion of ferric ions produced after irradiation. In this work, we used a portable nuclear magnetic resonance relaxometer to measure the relaxation times (which are important for dosimetric applications) of these gel materials. For this purpose, we performed a study for optimizing the acquisition parameters with a nuclear…
NUCLEAR MAGNETIC RESONANCE RELAXOMETRY AND IMAGING FOR DOSIMETRY WITH AGAROSE FRICKE GEL
2016
Introduction: Fricke Xylenol Gel (FXG) dosimetric system is based on the radiation induced oxidation of ferrous to ferric ions. In this kind of gels it can occur that ferrous and ferric ions diffuse in the gel matrix. To preserve the spatial distribution of the dose from diffusion, Fricke gels must be undergoing measurement within a few hours of their irradiation. Thus, the spatial integrity of the dose distribution in the Fricke gel is maintained. The oxidation of ferrous ions also causes a reduction of the longitudinal nuclear magnetic relaxation time which can be measured by means of nuclear magnetic resonance (NMR) instrumentation. In this work we performed NMR relaxometry and MR imagin…
Autism Spectrum Disorders: From Candidate Genes to Candidate Ontology Terms
2008
Genetic heterogeneity for a multifactorial disease such as autism would imply that any two patients are unlikely to share the same susceptibility loci. Since different susceptibility loci may affect the same function and since functions may be considered at different levels of analysis, the following question arises: at what phenotypic levels is convergence attained by different genes in autism ? This is an important question to answer in order to shed light on subcellular, cellular or multicellular structures and functions possibly involved in the pathogenesis of autism. Among the various attempts made to answer this question it is worth mentioning the use of the best available genetic inf…
Ground motion phenomena in Caltanissetta (Italy) investigated by InSAR and geological data integration
2008
Urban areas are frequently affected by ground instabilities of various origins. The location of urban zones affected by ground instability phenomena is crucially important for hazard mitigation policies. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has demonstrated its remarkable capability to detect and quantify ground and building motion in urban areas, especially since the development of Advanced Differential Interferometric SAR techniques (A-DInSAR). In fact, the high density of re.ectors like buildings and infrastructures in urban areas improves the quality of the InSAR signal, allowing sub-centimetric displacements to be reliably detected. The A-DInSAR techniques a…
