Determining exhaust fumes exposure in chainsaw operations
2016
Abstract The objective of this study was to investigate the inhalation exposure of forest operators to polycyclic aromatic hydrocarbons (PAHs) and BTEX (benzene, toluene, ethylbenzene and total xylenes) contained in the exhaust fumes released from chainsaws and to suggest possible countermeasures. The study was carried out in four silvicultural treatments (coppice clearcut, conifer thinning, conifer pruning, and sanitary cut), using three types of chainsaw fuel (normal two-stroke petrol mix and two alkylate fuels). Eighty personal air samples were collected; IOM samplers combined with Amberlite XAD-2 sorbent tubes were used for collecting PAHs and Radiello® samplers were used for BTEX. Resu…

Near-Infrared emission of O2 embedded in amorphous SiO2 nanoparticles
2011
We report an experimental study on the emission properties of O2 molecules loaded by a thermal diffusion process at 200 °C into high-purity silica nanoparticles with mean diameters of 7 and 40 nm. The embedded O2 features a singlet to triplet emission band peaked at 1272 nm in agreement with the band observed for bulk silica materials. The photoluminescence excitation spectra have been determined in the visible and in the infrared range and are characterized by narrow bands peaked at 691, 764,and 1069 nm, respectively. By comparison of the transition energies, the vibrational quanta have been determined for the ground and for both the excited states; the values found are lower than the corr…
Prediction of concrete materials compressive strength using surrogate models
2022
Using soft computing methods could be of great interest in predicting the compressive strength of Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC). Therefore, this study developed four soft computing techniques. The models are the Linear- relationship (LR), pure quadratic, M5P-tree (M5P), and artificial neural network (ANN). The models were trained and developed using 306 datasets comprising 11 input parameters, including the curing temperature (T), the water-to-cement ratio (w/c), silica fume (SF), cement content (C), fiber content (Fb), water (W), sand content (S), superplasticizer (SP), fiber aspect ratio (AR) and curing time (t). Experimental results were used and compared to t…

I supereroi tra sogno e realtà: fumetti, cinema e videogiochi nella realtà aumentata e virtuale
2017
Sembra ormai scontato affermare di essere immersi in un mondo in cui non si possa più fare a meno delle nuove tecnologie e la questione più interessante, infatti, non è analizzare il loro grado di permeazione nelle nostre vite ma, assodata la loro presenza inequivocabile, capire come siano usate rispetto al mondo che le ha precedute. In altre parole i media devono essere studiati in relazione all’ambiente in cui operano, prestando particolare attenzione al ruolo che ricoprono nel campo culturale. Anche i vecchi media, entrando in relazione con le nuove tecnologie, creano questo nuovo ambiente mediale e meritano particolare attenzione nell’analisi. Cinema, fumetto e videogioco non sono da me…
LA TRADUZIONE DEI FUMETTI: PILOTE IN iTALIA
2018
La rivista di fumetti italiana Pilot che ebbe breve vita nel corso degli anni Ottanta del secolo scorso è direttamente emanazione dell’omonino periodico francese Pilot che ha attraversato, influenzandola, trent’anni della fumettistica d’oltralpe. In questo articolo si prenderanno in considerazione le motivazioni e gli esiti delle trasposizione dei fumetti francesi contenuti in questa famosa rivista in italiano.
A Mesoporous 3D Hybrid Material with Dual Functionality for Hg2+Detection and Adsorption
2008
Dual-function hybrid material U1 was designed for simultaneous chromofluorogenic detection and removal of Hg(2+) in an aqueous environment. Mesoporous material UVM-7 (MCM41 type) with homogeneously distributed pores of about 2-3 nm in size, a large specific surface area exceeding 1000 m(2) g(-1), and nanoscale particles was used as an inorganic support. The mesoporous solid is decorated with thiol groups that were treated with squaraine dye III to give a 2,4-bis(4-dialkylaminophenyl)-3-hydroxy-4-alkylsulfanylcyclobut-2-enone (APC) derivative that is covalently anchored to the inorganic silica matrix. The solid was characterised by various techniques including X-ray diffraction, transmission…
Effect of some additives on the reactions in fly ASH-Ca(OH)2system
2004
Differential thermal analysis and thermogravimetry were used to evaluate the effect of some additives, such as CaSO4, CaCl2 and silica fume amorphous silica from ferrosilicon synthesis on the mechanism and kinetics of reactions occurring in fly ash-Ca(OH)2 system. The accelerating role of these additives was demonstrated from the data relating to Ca(OH)2 consumption in hydrated pastes, determined by TG measurements.
