Gli argenti delle confraternite di Bisacquino
2011
Le confraternite di Bisacquino nel XVIII secolo dotarono le chiese o cappelle in cui aveva sede il loro sodalizio di pregevoli suppellettili ed arredi sacri in argento, eseguiti da abili artisti palermitani, di cui si propongono i più significativi esempi The confraternities of Bisacquino in the eighteenth century equipped the churches or chapels where their association was based with valuable silver furnishings and sacred ornaments, made by skilled artists from Palermo, of which the most significant examples are proposed here.
SPS-assisted preparation of the Magnéli phase WO2.90 for thermoelectric applications
2013
We describe the preparation and simultaneous consolidation of WO2.90 by spark plasma sintering (SPS). SPS allows for the direct manufacturing of large amounts of consolidated material. Synchrotron powder X-ray diffraction indicates that the material is single phase. Microstructure analysis indicates that the pellet is fully dense, allowing high-temperature thermoelectric properties to be reliably measured. The as-prepared samples of WO2.90 reach a ZT of 0.1 at 1100 K.
EPR RESPONSE OF PHENOLIC SOLID STATE PELLETS FOR DOSIMETRY OF RADIO- THERAPEUTIC PHOTON AND ELECTRON BEAMS

Characterization of phenolic solid state pellets for ESR dosimetry with radio-therapeutic photon and electron beams
2018
Introduction Among the various dosimetric techniques used for characterizing the radiation beams used in radiation therapy, the electron spin resonance (ESR) arouses increasing interest for applications in various therapy procedures. In this work we report the ESR investigation of particular phenol compound (IRGANOX 1076) exposed to clinical photon and electron beams (Gallo et al., 2017). Methods Phenol (IRGANOX 1076 - Sigma Aldrich) pellets were produced also with paraffin (10% by weight). Phenol pellets were exposed to clinical photon and electron beams at various energies produced by a linear accelerator (LINAC) Siemens Primus (Siemens Medical Systems, CA, USA) installed at the Radiother…
Behaviour of a speargun with a novel muzzle - Comportamento di un fucile subacqueo con testata innovativa
2013
The paper presents the results of a numerical and experimental investigation performed on a barrel of a speargun equipped with two kinds of muzzle. In particular, a standard muzzle for speargun (having an elastic propulsion) has been compared with an innovative one called ‘roller’. This new muzzle is equipped with two rollers and special bands. The rubber bands, fixed at the lower side of the barrel, run through the rollers and are engaged in suitable seats of the shaft. These bands are, therefore, longer than the traditional ones and, consequently, with equal force applied by the diver, the roller speargun has a longer range. Thanks to the particular geometry of the new muzzle, one of the …
A pilot-scale study of struvite precipitation in a stirred tank reactor: Conditions influencing the process
2008
Currently, the two most developed techniques for recovering phosphorus from wastewater consist of the formation of calcium phosphates and struvite (MgNH(4)PO(4).6H(2)O). In this work the influence of the operational conditions on the struvite precipitation process (pH in the reactor, hydraulic retention time, and magnesium:phosphorus, nitrogen:phosphorus, and calcium:magnesium molar ratios) have been studied. Twenty-three experiments with artificial wastewater were performed in a stirred reactor. In order to obtain the pH value maintenance during the crystallization process, a fuzzy logic control has been developed. High phosphorus removal efficiencies were reliably achieved precipitating t…
Chlorinated dioxins and dibenzothiophenes in fly ash samples from combustion of peat, wood chips, refuse derived fuels and liquid packaging boards
1995
Abstract Peat, wood chips, refuse derived fuel and liquid packaging board in different combinations were burned at a temperature of at least 850 °C. Fly ash samples from these combustions were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzothiophenes (PCDBTs) by high resolution GC/MS. The concentrations of tri- and tetrachlorodibenzothiophenes and tri-, tetra- and pentachlorodioxins were highest when mixtures of wood chips and refuse derived fuel (RDF) were burned. The fly ash from the combustion of pure peat pellets did not contain any polychlorinated dibenzothiophenes. When wood chips and RDF were burned the concentrations of chlorinated compounds in fly…
Le suppellettili liturgiche dell'Eparchia di Piana degli Albanesi
2007
Il saggio analizza le suppellettili liturgiche d'argento dell'Eparchia di Piana degli Albanesi esposte alla mostra "Tracce d'Oriente", per lo più realizzate da argentieri palermitani del XVIII e XIX secolo. Le opere della liturgia greco-albanese vengono messe a confronto con quelle utilizzate per le celebrazioni di rito latino. The essay analyzes the silver liturgical furnishings of the Eparchy of Piana degli Albanesi exhibited at the exhibition "Tracce d'Oriente", mostly made by silversmiths from Palermo in the 18th and 19th centuries. The works of the Greek-Albanian liturgy are compared with those used for the Latin rite celebrations.
Bioflocculation of Euglena gracilis via direct application of fungal filaments: a rapid harvesting method
2021
Funding Information: Special thanks to the US Agricultural Research Service for the provision of fungal strains. Thanks also to Dr Marilyn Wiebe (Technical Research Centre of Finland) for her expert advice on fungi and Johanna Oja for her technical help. This research was enabled by funding from The Land and Water Technology Foundation, The Finnish Cultural Foundation, and The Finnish Foundation for Technology Promotion. Publisher Copyright: © 2021, The Author(s). The high cost and environmental impact of traditional microalgal harvesting methods limit commercialization of microalgal biomass. Fungal bioflocculation of microalgae is a promising low-cost, eco-friendly method but the range of …
