Un approccio GIS per la valutazione dell’equità di accesso alle cure per infarto acuto del miocardio in Sicilia
2012
Una delle principali cause di morte per Infarto Acuto del Miocardio (IMA) è ancora dovuta al tempo intercorso tra l’esordio ed il trattamento. Tale ritardo è attribuibile sia alla mancanza di consapevolezza sui sintomi di infarto che al tempo necessario per raggiungere la struttura ospedaliera. Ciò può comportare un diseguale accesso ai trattamenti ospedalieri in termini di tempestività delle cure e di conseguenza esiti differenti in funzione della distanza delle strutture ospedaliere dalla residenza dei singoli utenti. Obiettivo del presente lavoro è quello di analizzare la distribuzione territoriale delle strutture ospedaliere in Sicilia al fine di individuare le aree comunali più distant…
A View from the Garden: Contemplative Isolation and Constructive Sociability in Lucretius and in the Epicurean Tradition
2021
It is often assumed that Epicurean philosophy and its foremost Roman prophet, T. Lucretius Carus, adopted a deeply hostile attitude towards both politics and religion. Individualistic (or even solipsistic) interpretations of Epicureanism – as well as of the Epicurean catechism of De Rerum Natura – have long co-existed with, and provided support to, the claim that the Epicureans attached little value to religious experiences. In the present paper, I shall argue that, in this and many other respects, the modern reception of Epicureanism – with its brave aspirations after the liberation of science from social and religious restraints – has had undue influence on our understanding of De Rerum N…
Lucrezio e la biologia di Aristotele. Riflessioni sulla presenza dell'opera aristotelica nel 'De rerum natura' e nella cultura greco-latina del I sec…
2006
Dopo avere preliminarmente constatato l'importanza che il sapere biologico, e in particolare la biologia di tradizione aristotelico-peripatetica, rivestono nel pensiero scientifico lucreziano, si intraprende una ricerca specifica sulle forme e le modalità di contatto ipotizzabili fra l'autore del 'De rerum natura' e il 'corpus' filosofico del Peripato. Alla luce della bibliografia degll'ultimo secolo, spesso discordante, si cerca di ricostruire in una visione più ampia la funzione svolta da Aristotele e dalla riflessione naturalistica della sua scuola nel dibattito etico-culturale greco-latino del I secolo a. C. Particolare attenzione viene prestata al tessuto speculativo e letterario dell'…
Chaos Synchronization Based on Unknown Input Proportional Multiple-Integral Fuzzy Observer
2013
Published version of an article in the journal: Abstract and Applied Analysis. Also available from the publisher at: http://dx.doi.org/10.1155/2013/670878 Open Access This paper presents an unknown input Proportional Multiple-Integral Observer (PIO) for synchronization of chaotic systems based on Takagi-Sugeno (TS) fuzzy chaotic models subject to unmeasurable decision variables and unknown input. In a secure communication configuration, this unknown input is regarded as a message encoded in the chaotic system and recovered by the proposed PIO. Both states and outputs of the fuzzy chaotic models are subject to polynomial unknown input with kth derivative zero. Using Lyapunov stability theory…
Assessment of a possible genotoxic environmental risk in sheep bred on grounds with strongly elevated contents of mercury, arsenic and antimony.
1996
A part of Northern Palatinate country (Germany) was formerly influenced by mercury mining. Today, in many cases agricultural and housing areas are placed onto or near to former dump grounds of rubble. In the soil of these areas the concentration of mercury, arsenic and antimony was found ranging from basic natural contents up to strongly elevated levels. In a biomonitoring project, sheep bred on grounds contaminated with mercury (range 1-435 mg Hg/kg dry matter), arsenic (range 17-147 mg As/kg dry matter) and antimony (range 2-15 mg Sb/kg dry matter) were taken as example on the uptake of these elements from the environment and for possible effects of this exposure. Significantly elevated m…
Degassing of gaseous (elemental and reactive) and particulate mercury from Mount Etna volcano (Southern Italy)
2007
Abstract There is an urgent need to better constrain the global rates of mercury degassing from natural sources, including active volcanoes. Hitherto, estimates of volcanic fluxes have been limited by the poorly determined speciation of Hg in volcanic emissions. Here, we present a systematic characterisation of mercury partitioning between gaseous (Hg(g)) and particulate (Hg(p)) forms in the volcanic plume of Mount Etna, the largest open-vent passively degassing volcano on Earth. We demonstrate that mercury transport is predominantly in the gas phase, with a mean Hg(p)/Hg(g) ratio of ∼0.01 by mass. We also present the first simultaneous measurement of divalent gaseous mercury ( Hg ( g ) II …
Mercury and halogen emissions from Masaya and Telica volcanoes, Nicaragua
2008
We report measurements of Hg, SO2, and halogens (HCl, HBr, HI) in volcanic gases from Masaya volcano, Nicaragua, and gaseous SO2 and halogens from Telica volcano, Nicaragua. Mercury measurements were made with a Lumex 915+ portable mercury vapor analyzer and gold traps, while halogens, CO2 and S species were monitored with a portable multi gas sensor and filter packs. Lumex Hg concentrations in the plume were consistently above background and ranged up to 350 ng m-3. Hg/SO2 mass ratios measured with the real-time instruments ranged from 1.1 × 10-7 to 3.5 × 10-5 (mean 2 × 10-5). Total gaseous mercury (TGM) concentrations measured by gold trap ranged from 100 to 225 ng m-3. Reactive gaseous m…

Multicommutation cold vapour atomic fluorescence determination of Hg in water.
2002
Abstract A multicommutation-based method has been developed for the on-line direct atomic fluorescence spectrometric (AFS) determination of Hg in waters without any previous sample treatment. The performance of the proposed procedure has been compared with that of a conventional AFS system based on continuous mode measurements. In short, the use of multicommutation, together with a reduction of the size of the liquid–gas phase separator, provides an increase of the laboratory productivity by improving the sample throughput by a factor of 3.6 and strongly reduces the sample consumed by a factor of 6 and reagent consumed by a factor of 8.4. The waste generation is reduced by a factor of 2.4 a…
