Fluorination of Cu(001) Surface by C60F48 Molecule Adsorption
2019
Copper surface functionalization by defluorination of C60F48 molecules with submonolayer and monolayer coverages on the Cu(001) crystal is studied by X-ray photoelectron spectroscopy. At room tempe...
Perception of non-processed semi-hard cheese aroma
2012
Perception of the aroma of food products depends on several factors, involving both the. chemical composition of food and human neurophysiology. The perception of food flavour,. including cheese often relies on the perception of several aroma compounds in mixture in. balanced proportions. The existence of perceptual interactions among aroma compounds in. mixtures and also the release of aroma compounds from the food product are the main factors. that influence the global perceived aroma of food. Hence, the objective of this PhD study was. to investigate the mixture of aroma compounds representing the aroma of semi-hard cheese by. taking into account perceptual interactions among odorants an…
Pleurotus ostreatus volatile aroma compounds identified from fruit-body and from mycelium grown in submerged and solid-state cultures
2003
Comparative analyses of volatile aroma compounds of the Pleurotus ostreatus JMO.95 fruit-body and its corresponding mycelium grown in liquid, on agar surface, or on solid support cultures have been carried out by dynamic headspace concentration using GC/MS and GC/sniffing. The aroma of the fruit-body was due essentially to the presence of octan-3-one and, in a lesser extent, to the presence of octan-3-ol. Other compounds, such as oct-l-en-3-ol, oct-l-en, 2-methylbutanol and a-pinene were also present in low concentrations. The comparison of the aromatic spectra of the fruit-body with the aromatic spectra of mycelia obtained under different culture conditions indicated that the main aromatic…

Características y visibilidad de las revistas españolas de ciencias de la salud en bases de datos
2015
Se describen las características de 207 revistas españolas de ciencias de la salud activas en 2014 y su visibilidad en seis bases de datos biomédicas y multidisciplinares. Scopus e Ibecs son las bases de datos que mayor número de revistas cubren, y Medline y WoS las que menos. La disciplina mejor representada es medicina, seguida de psicología, enfermería y farmacia. Se observa la práctica ausencia de revistas editadas exclusivamente en papel, la existencia de revistas publicadas en inglés, el aumento de versiones bilingües español-inglés y el acceso gratuito a los contenidos. El artículo incorpora el censo de revistas, que puede servir de referencia para los investigadores para selecciona…
LE CLAUSOLE GENERALI
2002
L'autore propone una ricostruzione del dibattito sulle clausole generali alla luce dei valori emergenti dal sistema giuridico ordinamentale. Vengono analizzate le singole clausole e le corrispondenti figure sintomatiche individuate dalla giurisprudenza, in una visione di insieme in grado di tracciare le linee di demarcazione ed i rapporti di connessione tra le stesse.
ROS/Gazebo Based Simulation of Co-operative UAVs
2019
UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…
Vivante, Cesare
2020
Una biografia, privata e intellettuale, di Cesare Vivante (1855-1944), maestro indiscusso della scienza italiana del diritto commerciale. Vivante impresse alla giuscommercialistica italiana un’identità culturale e metodologica che trascese le generazioni e le appartenenze, elevandosi ad elemento fondante di una tradizione nazionale di altissimo profilo. Fece del diritto una «scienza di osservazione», una scienza empirica, impregnata di venature positivistiche e sociologiche. Esercitò dall'inizio alla fine della sua lunga carriera una profonda critica, di orientamento democratico e sociale, al diritto privato italiano. A private and intellectual biography of Cesare Vivante (1855-1944), consi…
Look at them and they will notice you : Distractor-independent attentional capture by direct gaze in change blindness
2018
Humans have shown a detection advantage of direct vs. averted gaze stimuli in visual search tasks. However, instead of attentional capture by direct gaze, the detection advantage in visual search may depend on attention-grabbing potential of the distractor stimuli to which the target needs to be compared. We investigated attentional capture by direct gaze using the change blindness paradigm, in which successful detection does not require comparison between the target and the distractor items. Participants detected a masked gaze direction change in one of four simultaneously presented schematic faces. The distractor gaze directions were systematically varied across three experiments. Changes…
Expressive suppression and enhancement during music-elicited emotions in younger and older adults
2015
International audience; When presented with emotional visual scenes, older adults have been found to be equally capable to regulate emotion expression as younger adults, corroborating the view that emotion regulation skills are maintained or even improved in later adulthood. However, the possibility that gaze direction might help achieve an emotion control goal has not been taken into account, raising the question whether the effortful processing of expressive regulation is really spared from the general age-related decline. Since it does not allow perceptual attention to be redirected away from the emotional source, music provides a useful way to address this question. In the present study…
