Responses of Rhynchophorus ferrugineus adults to selected synthetic palm esters: electroantennographic studies and trap catches in an urban environme…
2011
The Red Palm Weevil (RPW), Rhynchophorus ferrugineus Olivier, accidentally introduced in the European countries facing the Mediterranean basin, is becoming the most serious pest for ornamental palms in the urban environment. In our work we tested electroantennogram (EAG) and behavioural responses of RPW adults to five selected synthetic palm esters: ethyl propionate, ethyl butyrate, ethyl isobutyrate, ethyl lactate and ethyl acetate. EAG bioassays showed higher sensitivity of female antennae compared to male antennae for test compounds. Differences were also recorded in the EAG responses using different esters and doses. Ethyl propionate was the synthetic ester that elicited the strongest r…
Transverse momentum distributions for exclusive $\varrho^{0}$ muoproduction
1992
We have studied transverse momentum distributions for exclusive rho(0) muoproduction on protons and heavier nuclei at 2 < Q2 < 25 GeV2. The Q2 dependence of the slopes of the p(t)2 and t' distributions is discussed. The influence of the non-exclusive background is investigated. The p(t)2-slope for exclusive events is 4.3 +/- 0.6 +/- 0.7 GeV-2 at large Q2. The p(t)2 spectra are much softer than inclusive p(t)2 spectra of leading hadrons produced in deep inelastic scattering.
Pioneers as Peers : How Entrepreneurial Journalists Imagine the Futures of Journalism
2021
The article investigates the futures of journalism that pioneering entrepreneurial journalists anticipate. This comprises the different imaginaries that journalists employ to make sense of journalism’s present potentials, anticipate its possible futures, and inform their decision-making. By analysing semi-structured interviews with Finnish entrepreneurial journalists, the article identifies a peer-to-peer imaginary on which the interviewees draw and construct to anticipate the potential futures of journalism. In this peer-to-peer imaginary, journalism is produced in journalists’ and audiences’ peer networks of affinity and shared interests. The imaginary promises elevated audience engagemen…
Tree age‐dependent changes among epiphytic bryophyte communities in Mediterranean environments. A case study from Sicily (Italy)
2010
Abstract The epiphytic bryophytes inhabiting trees of different size/age in a Quercus ilex wood from Madonie Mountains (northern Sicily, Italy) were studied with the purpose of describing the changes that take place in the bryophyte stratum during the tree lifespan. Results indicate an increase of bryophyte cover combined with a progressive decrease of epiphytic lichens and the existence of an active process of species and community substitution. The way these processes take place corresponds to a succession sequence, which is characterised by a high number of pioneer species on the youngest trees and a sharp decline of species number on middle‐aged and old trees due to the great spread of …
Chemical composition of the essential oil from Pulicaria vulgaris var. graeca (Sch.-Bip.) Fiori (Asteraceae) growing wild in Sicily and its antimicro…
2015
In this study the chemical composition of the essential oil from aerial parts of Pulicaria vulgaris var. graeca (Sch.-Bip.) Fiori collected in Sicily was evaluated by GC and GCâMS. The main components of P. vulgaris var. graeca oil were hexadecanoic acid (21.7%), β-caryophyllene (14.3%) and geranyl propionate (8.2%). The comparison with other studied oils of genus Pulicaria is discussed. Antibacterial activity against several bacteria, including some ones infesting historical art craft, was also determined.

SEU characterization of commercial and custom-designed SRAMs based on 90 nm technology and below
2020
International audience; The R2E project at CERN has tested a few commercial SRAMs and a custom-designed SRAM, whose data are complementary to various scientific publications. The experimental data include low- and high-energy protons, heavy ions, thermal, intermediate- and high-energy neutrons, high-energy electrons and high-energy pions.

Giuseppa Balsamo(*)- Giuseppe Ingrassia(**) ANALISI DI TALUNI ASPETTI DELL’ OFFERTA TURISTICA DELLA VILLA ROMANA DEL CASALE E DEL TERRITORIO CIRCOSTANTE ALLA LUCE DI UNA INDAGINE CAMPIONARIA Riassunto Questa ricerca ha lo scopo di far conoscere le opinioni dei visitatori/turisti dopo la visita dell’importante Sito archeologico siciliano denominato Villa Romana del Casale (nel prosieguo“Villa”) di Piazza Armerina (EN). L’obiettivo principale della ricerca è quello di migliorare l’offerta turistica e di incentivare le visite sia alla Villa che in tutta l’Area circostante, costituita anche dal Museo regionale di Aidone, dall’Area archeologica di Morgantina e dal Museo di Enna, al fine di dare …
