Architectures for autism
2015
Le ricerche condotte sulle malattie degenerative della "terza età", hanno visto negli ultimi anni il gruppo di studio palermitano indagare e proporre soluzioni che vanno dalla stesura di linee guida per la progettazione di Residenze Sanitarie Assistenziali (RSA), alla progettazione esecutiva di architetture residenziali, al recupero e riuso di edilizia già esistente fino alla progettazione dello spazio domestico dedicato e protetto, che oltre a fornire risposte funzionali ne ha anche esaltato il design degli elementi di arredo. A questo ambito di ricerca da circa due anni si è affiancato un nuovo settore di indagine indirizzato sempre alle "minoranze sociali". Research conducted on degenera…
Characterization of automotive shredder residues before and five years after landfill disposal
2015
The paper illustrates the results of an extensive analytical characterization study of automotive shredder residues (ASR), also known as "fluff". The analyses concerned material fractions and their content, with special reference to heavy metals (e.g. Cd, Cr, Hg, Pb, Cu) and arsenic. Elution tests on the original materials were also conducted. Moreover, chemical concentrations of ASR samples after about five years' landfill residence was assessed, in order to verify possible changes resulting from both in-situ leaching and organic matter degradation phenomena. Results show that lead seems to be the most critical element in view of possible ASR acceptance in non-hazardous waste landfills bec…
The sanitation service of seagrasses – Dependencies and implications for the estimation of avoided costs
2022
Seagrasses are capable of sanitizing coastal seawaters polluted by fecal bacteria. In this work, the reduction of Enterococci concentration in the presence of a seagrasses’ assemblage (Pacific Ocean) was related to the decrease in the probability of gastroenteritis. A linear model fitted to data extracted from the literature showed a 20% reduction of this probability in the presence of these plants. Seagrass sanitation effect was estimated to allow avoiding ca. 24 million gastroenteritis cases/year, globally. Considering a global cost of gastroenteritis of ca. US$ 372 million/year, the global avoided cost, assuming that the sanitation service was always effective, was estimated to be ca. US…

Differential branching fractions and isospin asymmetries of B -> K ((*)) μ(+) μ(-) decays
2014
The isospin asymmetries of $B \to K\mu^+\mu^-$ and $B \to K^{*}\mu^+\mu^-$ decays and the partial branching fractions of the $B^0 \to K^0\mu^+\mu^-$, $B^+ \to K^+\mu^+\mu^-$ and $B^+ \to K^{*+}\mu^+\mu^-$ decays are measured as functions of the dimuon mass squared, $q^2$. The data used correspond to an integrated luminosity of 3$~$fb$^{-1}$ from proton-proton collisions collected with the LHCb detector at centre-of-mass energies of 7$\,$TeV and 8$\,$TeV in 2011 and 2012, respectively. The isospin asymmetries are both consistent with the Standard Model expectations. The three measured branching fractions, while individually consistent, all favour lower values than their respective Standard M…

Bacterial Community Structure of an IFAS-MBRs Wastewater Treatment Plant
2017
TIn this work, the bacterial community putatively involved in BNR events of a UCT-MBMBR pilot plant was elucidated by both culture-dependent and metagenomics DNA analyses. The presence of bacterial isolates belonging to Bacillus (in the anoxic compartment) and to Acinetobacter, Stenotrophomonas, Rhodococcus, Escherichia and Aeromonas (in the aerobic compartment) is in agreement with the nitrification/denitrification processes observed in the plant. Moreover, the study of bacterial community structure by NGS revealed a microbial diversity suggesting a biochemical complexity which can be further explored and exploited to improve UCT-MBMBR plant performance.
Trade me an axe? Interpretive challenges of the distribution and provenance of Neolithic basaltic bifacial tools in Israel
2016
The discovery of a Neolithic quarry and production site for basanite bifacial tools at Giv�at Kipod in Israel has provided new insights into these socially significant artefacts. Geochemical analysis of material from the quarry distinguishes it from other basaltic rock sources in Israel, allowing stone tools from a variety of sites and dated contexts to be assigned a provenance. Results suggest that Giv�at Kipod was an important production centre for over several millennia. It operated primarily on a local, regional level and independently of the parallel manufacture-and-distribution mechanisms of flint bifacials. While flint tools developed in response to the practical requirements of the …
Geochemical discrimination of basaltic sources as a tool for provenance analyses of bifacial tools in the southern Levant: first results from the Jez…
2013
Abstract The determination of groundstone tool sources bears the potential to examine aspects like raw material selection and preference, mobility, trade and exchange patterns, control over resources and long term use of raw material sources. The discovery of the Neolithic/Chalcolithic basanite bifacial quarry of Giv'at Kipod in the Jezreel Valley, Israel, provides the opportunity of raw material centred provenance studies of bifacials in the southern Levant. The basis for reliable provenance analyses is a clear geochemical characterization of the extraction site and its discrimination from other potential sources. To achieve this, the Miocene magmatic rocks of the Jezreel Valley were sampl…
Impiego di batteri lattici autoctoni per il miglioramento igienico-sanitario del Pecorino Siciliano DOP
2017
Il Pecorino Siciliano DOP è considerato il più antico formaggio prodotto in Sicilia e, probabilmente, d’Europa. Le citazioni storiche sulla sua antica origine risalgono al IX secolo a.C. in uno dei passi più famosi dell’odissea di Omero, quando Ulisse incontra Polifemo. In seguito, anche Aristotele e Plinio esaltano il gusto unico di questo formaggio. In particolare, proprio Plinio, nella sua opera “Naturalis Historia”, redige una carta dei formaggi nella quale vengono citati, tra i migliori pecorini,quelli provenienti da Agrigento. Fra le caratteristiche peculiari del Pecorino Siciliano DOP vanno annoverati il sapore leggermente piccante e l’incantevole profumo di pascolo. Il Pecorino Sici…
