Composition of the essential oil of allium neapolitanum cirillo growing wild in sicily and its activity on microorganisms affecting historical art cr…
2015
Essential oil of the aerial parts of Allium neapolitanum Cirillo collected in Sicily were analyzed by gas-chromatography-flame-ionization detection and gas-chromatography-mass spectrometry. Nineteen compounds were identified in the oil and the main components were found to be (E)-chrysanthenyl acetate (28.1%), (Z)-chrysanthenyl acetate (23.8%), (E)-β-farnesene (9.6%), dimethyl trisulfide (9.6%), camphor (7.4%), methyl allyl disulfide (6.8%) and 1-methyl-3-allyl trisulfide (5.8%). The essential oil showed good antimicrobial activity against 11 strains of test microorganisms, including several species infesting historical material.
Regional passenger transport. A comparison analysis between helicopter and seaplane
2014
Heliports and seaplane bases are relatively small infrastructures able to serve medium or low volumes of regional traffic in poor accessible areas or in zones just located to the next proximity of the urban areas. The spatial extension of the airside is directly connected with the costs of the infrastructure and it is primarily determinate by the type of aircraft that uses the infrastructure and secondarily by the design expected traffic. The helicopter infrastructure is far smaller than that required for airplanes and seaplanes, since the first doesn’t suffers the lateral wind on the approach and landing direction. On the other hand, the rotorcraft suffers operative costs largely high than…
Implementing the sustainable energy (and climate) action plans: quasi-steady state or dynamic building modeling approach?
2020
Actions contemplated in Sustainable Energy (and Climate) Action Plans (SEAPs), which municipalities adhering to the EU initiative called “The Covenant of Mayors” are required to prepare, regard many sectors, among which are buildings. To implement such plans, it is necessary to make use of methods for predicting energy use in buildings. Technicians involved in this tend to adopt easy-touse simulation models because of the common mid-level expertise of the offices involved. However, such simplified methods could result in a less accurate evaluation of the energy demand of buildings. In this paper the suitability of the quasi-steady state and the dynamic approach, in the frame of these new ur…
Performance of the first reverse electrodialysis pilot plant for power production from saline waters and concentrated brines
2016
Abstract This work reports experimental data collected for the first time on a full-scale RED pilot plant operated with natural streams in a real environment. The plant – located in the South of Italy – represents the final accomplishment of the REAPower project ( www.reapower.eu ). A RED unit equipped with almost 50 m2 of IEMs (125 cell pairs, 44x44 cm2) was tested, using both artificial and natural feed solutions, these latter corresponding to brackish water (≈0.03 M NaClequivalent) and saturated brine (4–5 M NaClequivalent). A power output up to around 40 W (i.e. 1.6 W/m2 of cell pair) was reached using natural solutions, while an increase of 60% was observed when testing the system with…
Towards 1 kW power production in a reverse electrodialysis pilot plant with saline waters and concentrated brines
2017
Abstract Reverse electrodialysis (RED) is a promising technology to extract energy from salinity gradients, especially in the areas where concentrated brine and saline waters are available as feed streams. A first pilot-scale plant was recently built in Trapani (Italy), and tested with real brackish water and brine from saltworks. The present work focuses on the scale-up of the pilot plant, reaching more than 400 m 2 of total membrane area installed and representing the largest operating RED plant so far reported in the literature. With a nominal power capacity of 1 kW, the pilot plant reached almost 700 W of power capacity using artificial brine and brackish water, while a 50% decrease in …
CFD analysis of concentration polarization phenomena in spacer-filled channels for Reverse Electro-Dialysis
2012
In this work, carried out within the EU-FP7 funded REAPower project, CFD simulations were carried out in order to study the fluid flow behaviour and mass transport phenomena within spacer-filled channels.

Le armi dal santuario di contrada Mango a Segesta
2022
The research focuses on weapons coming from the extra-urban sanctuary of contrada Mango in Segesta, investigated between the fifties and sixties of the 20th century. The study illustrates the types and chronology of the »indigenous« and Greek weapons (mainly defensive) attested in the sanctuary, and clarifies and discusses the location of the finds (along the south, north and east peribolos walls). Finally, the research tries to understand the function and role of the weapons in the sacred area. This category of votives is also interpreted in the light of other findings from the sanctuary that refer to war, mainly some fragments of a Parian marble statue of Nike of the middle of the 5th cen…
Giuseppe Sigismondo, Apoteosi della musica del Regno di Napoli, a cura di C. Bacciagaluppi, G. Giovani e R. Mellace, con un saggio introduttivo di R.…
2018
Review of the first edition of Sigismondo's "Apoteosi", a detailed and very interesting history of the music in Naples from the Sixteenth to the early Nineteenth Century. The work is a mailstone in the process of construction and diffusion of the myth of the "Neapolitan School" in composition.
