L’autocontrollo della soggettività nella ricerca empirica
2019
Per promuovere un atteggiamento scientifico negli insegnanti, i ricercatori che usano un metodo empirico in campo educativo, devono autocontrollarsi affinché, consapevolmente o no, alcuni atteggiamenti personali non inficino la validità dei risultati ottenuti. To promote a scientific attitude in teachers, researchers who use an empirical method in the educational field, they have to self-control so that, knowingly or not, some personal attitudes do not affect validity of the results achieved.
UN NUOVO MODELLO PER LA STIMA DELL’ERODIBILITÀ RILL
2015
Molti modelli process-oriented per la previsione dell’erosione rill utilizzano parametri, come l’erodibilità rill, che sono specifici del sito di interesse e pertanto l’applicazione dei suddetti modelli necessita la misura di questi parametri o una loro stima indiretta. L’obiettivo del presente lavoro è quello di proporre un metodo per la misura indiretta dell’erodibilità rill del suolo dell’area sperimentale di Sparacia, in Sicilia. Sono state utilizzate le misure condotte sui rill rilevati nelle parcelle di Sparacia in occasione di sette eventi di pioggia naturale e un semplice approccio matematico basato sull’equazione che simula il distacco dei sedimenti tenendo conto della variabilità …
Comparación del Vitalograph COPD-6® y del Air Smart Spirometer® con la espirometría estándar en el despistaje y el diagnóstico de los pacientes con E…
2020
La enfermedad pulmonar obstructiva crónica (EPOC) está infradiagnosticada aunque mejora su evo- lución y pronóstico si se trata precozmente y su principal tratamiento es la abstinencia tabáquica. El objetivo principal de este estudio es comparar los espirómetros de campo COPD-6 ® (Vitalograph) y Air Smart Spirometer® con la espirometría estándar en el diagnóstico de la obstrucción bronquial. Los objetivos secundarios son: determinar cuál de los dos espirómetros estudiados es más eficaz y/o eficiente; detectar los falsos positivos que generan y valorar su aportación a la deshabituación tabá- quica. Participaron 185 pacientes del Centro de Salud Fuensanta con o sin síntomas o signos sugestivo…
Escalating CO2 degassing at the Pisciarelli fumarolic system, and implications for the ongoing Campi Flegrei unrest
2019
Abstract This short communication aims at providing an updated report on degassing activity and ground deformation variations observed during the ongoing (2012–2019) Campi Flegrei caldera unrest, with a particular focus on Pisciarelli, currently its most active fumarolic field. We show that the CO2 flux from the main Pisciarelli fumarolic vent (referred as “Soffione”) has increased by a factor > 3 since 2012, reaching in 2018–2019 levels (>600 tons/day) that are comparable to those typical of a medium-sized erupting arc volcano. A substantial widening of the degassing vents and bubbling pools, and a further increase in CO2 concentrations in ambient air (up to 6000 ppm), have also been detec…
Experimental Analysis of the Thermal Performance of Wood Fiber Insulating Panels
2023
During the last decades, attention to energy and environmental problems has significantly grown, along with the development of international and national policies addressing sustainability issues. In the construction sector, one of the most widespread energy efficiency strategies consists of thermal insulation of buildings thanks to external insulating panels. Among these, wood fiber is an insulating material characterized by a natural, eco-sustainable and biodegradable structure, coming from the recycling of waste wood from sawmills. The present study aimed to characterize small test building insulated with wood fiber panels from the thermal point of view, comparing the results with those …
Antimicrobial and Antioxidant Activities of Coumarins from the Roots of Ferulago campestris (Apiaceae)
2009
We report the isolation of several coumarins and the stereochemical assessment of some pyranocoumarins, as well as the antibacterial and antioxidant activities of the three most abundant ones (grandivittin, agasyllin and aegelinol benzoate) isolated from the roots of Ferulago campestris collected in Sicily and of the hydrolysis product (aegelinol). Aegelinol and agasyllin showed antibacterial activity against nine ATCC and the same clinically isolated Gram-positive and Gram-negative bacterial strains. At a concentration between 16 and 125 μg/mL both coumarins showed a significant antibacterial effect against both Gram-negative and Gram-positive bacteria. In particular the ATCC strains Staph…
Internet e campagne elettorali: la prospettiva dell'ordinamento italiano
2021
This paper intends to discuss the issue of regulation of social networks as a media space employed by political actors (individuals or organizations) for the formation of public opinion and the construction of consensus in the context of the electoral campaigns: in more synthetic terms, social networks as an instrument of electoral propaganda. The main subject of my essay will concern, therefore, the problems de iure condito and de iure condendo about the subjection of communication on social media to rules aimed at ensuring a fair comparison between parties, lists, candidates in the electoral competition and, with it, the value of freedom and authenticity of the vote that emanates from art…

Aplicacions de mètodes no pertorbatius a la dinàmica del sabor
2008
RESUMEN A día de hoy, el Modelo Estándar de las interacciones electrodébiles describe correctamente todos los fenómenos observados en la naturaleza. Sin embargo no proporciona ninguna explicación al hecho de que existan tres familias fermiónicas, incluyendo cada una quarks y leptones. Estas familias se distinguen por el grado de libertad sabor. Debido a la ruptura espontánea de la simetría local gauge, existe un patrón de sabor muy rico. En particular, las partículas tienen masas diferentes, y las diversas familias se mezclan (en el caso de los quarks) cuando interaccionan con los bosones mediadores. El conocimiento preciso de las masas y ángulos de mezcla de los quarks es fundamental para …
