Food partitioning between Serranus scriba and Scorpaena porcus (Perciformes) on the infralittoral ground of the South Tyrrhenian Sea.

1993

Food preferences of Scorpaena porcus and Serranus scriba were investigated from the stomach contents of fish caught with trammel nets in the Gulf of Palermo (Tyrrhenian Sea). Decapoda Natantia and Decapoda Brachyura were the main preferred prey in the diet of S. porcus whereas Decapoda Natantia, Decapoda Galatheidae and Pisces were the preferred prey for S. scriba. These results and the values of the index of overlapping alimentary requirements suggested competition for food resources between the two species. A more precise investigation, at species level, of the food remains of the most abundant taxon (Crustacea Decapoda) made it possible to demonstrate that the trophic niche overlap betwe…

STUDIO DI UN AMMORTIZZATORE ELETTROMAGNETICO A RECUPERO DI ENERGIA

2013

Questo lavoro ha come obiettivo principale lo studio teorico e con supporto di software F.E.M. di un dispositivo che consenta recupero energetico da una sospensione automobilistica. In sostituzione allo smorzatore viscoso, che dissipa l’energia cinetica del veicolo a seguito dell’attraversamento di strade sconnesse o ostacoli più marcati, si è usato uno smorzatore elettromagnetico che svolga le funzioni dello smorzatore viscoso consentendo un recupero di energia elettrica. Lo smorzatore elettromagnetico è di tipo a magneti permanenti e il suo funzionamento si basa sul fenomeno dell’induzione elettromagnetica. Il modello matematico descrive il funzionamento dello smorzatore, restituendo i va…

Settore ING-IND/14 - Progettazione Meccanica E Costruzione Di MacchineMain objective of this work is the theoretical study and support of FEM software of a device that allows for energy recovery from an automotive suspension. In replacing the viscous damper which dissipates the kinetic energy of the vehicle due to rough roads or obstacles more marked an electromagnetic damper is used that performs the functions of the viscous damper allowing a recovery of electricity. The damper is of the electromagnetic type with permanent magnets and its operation is based on the phenomenon of electromagnetic induction. The mathematical model describes the operation of the damper restoring the values of the electrical and mechanical magnitudes as a function of the relative speed between the rod and the stator. Energy recovery has been estimated considering an electric minicar that transits on a bumpy road. The recovered power has a total value of about 250W.

Phosphate ions detection by using an electrochemical sensor based on laser-scribed graphene oxide on paper

2023

In this work, electrodes based on laser-scribed reduced graphene oxide were fabricated using filter paper as the substrate. To fabricate the electrodes, a water suspension of graphene oxide was filtered to produce a continuous and uniform film of graphene oxide on the filter paper surface. Subsequently, a CO2 laser was used to "write" the working, counter and reference eelctroes by reducing graphene oxide in specific areas to define complete sensors. Referecnce electrodes were then coated with a commercial Ag/AgCl conductive paste to produce a quasi Ag/AgCl reference. As fabricated devices were employed as electrochemical sensors for detection of phosphate ions in water by employing the mol…

Rateless Codes Performance Analysis in Correlated Channel Model for GEO Free Space Optics Downlinks

2012

Settore ING-INF/03 - TelecomunicazioniFree Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth high rate capability immunity to electromagnetic interference and small equipment size. Thus they are suitable for inter-satellite links deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 106 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets.Settore ING-INF/01 - Elettronica

Prospettive di riforma della tutela penale dell'ambiente nel diritto europeo e sovranazionale

2021

Il saggio descrive le prospettive di riforma della normativa penale ambientale, di recente delineatesi tanto a livello internazionale, quanto in ambito europeo. Pur non spingendosi sino a prevedere i possibili esiti delle dinamiche in corso, il contributo non rinuncia ad analizzarne luci ed ombre, anche alla luce delle difficoltà di tipizzazione delle fattispecie incriminatrici determinata dalla particolare complessità della materia ambientale.

Settore IUS/17 - Diritto PenaleThe essay describes the prospects of reform of environmental criminal law recently outlined both at international and European level. Although the contribution does not go so far as to predict the possible outcomes of the dynamics in progress it does not shy away from analysing the lights and shadows also in the light of the difficulties of typifying criminal offences determined by the particular complexity of environmental matters.

Fautes musicales et fautes textuelles dans les lais lyriques transmis par les chansonniers du Roi (M) et de Noailles (T)

2020

In this contribution we shall present some anomalies in the musical notation of the anonymous lyric lais transmitted by French chansonniers M and T (i.e. Kievrefoil, Markiol and Nompar), which share the same source, and to which a recently discovered chansonnier fragment (Bo) can be added. The plural attestation of these heterostrophic texts allows to nuance the strict notion of musical error, advocated by John H. Marshall for this very corpus. Finally, we discuss an interesting case (Nompar, str. X) where musical notation can effectively help the reconstruction of a text corrupted in both witnesses.

Use of ICS in COPD: From Blockbuster Medicine to Precision Medicine

2017

Chronic obstructive pulmonary disease (COPD) is a major cause of mortality worldwide, whose burden is expected to increase in the next decades, because of numerous risk factors, including the aging of the population. COPD is both preventable and treatable by an effective management including risk factor reduction, prevention, assessment, and treatment of acute exacerbations and co-morbidities. The available agents approved for COPD treatment are long-acting or ultra-long-acting β2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) bronchodilators, as well as inhaled corticosteroids (ICS) in combination with LABAs. ICS use has been restricted only to selected COPD patients by th…

Resilience and Parental Burnout Among Finnish Parents During the COVID-19 Pandemic: Variable and Person-Oriented Approaches.

2021

During the coronavirus disease 2019 (COVID-19) crisis, different personality characteristics may have influenced parental well-being in different ways. In the present study, we combined variable and person-oriented approaches and examined relationships between resilience, parental burnout, and perfectionism during the lockdown. We first used structural equation modeling to assess the paths between variables. We then used latent profile analysis to examine different profiles of parents based on resilience, perfectionism, and symptoms of parental burnout. Finally, we examined how these profiles differ in terms of relevant background variables. The results showed that resilience predicted par…
