Solar neutrino physics with Borexino
2018
We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the {\it pp} fusion chain have been made. It is the first time that the same detector measures the entire range of solar neutrinos at once. These new data weakly favor a high-metallicity Sun. Prospects for measuring CNO solar neutrinos are also discussed.
Wind gustiness and sulphur dioxide concentration in the urban area of Barcelona, Spain
1991
Abstract Data on aerosols and wind parameters recorded at the Barcelona Meteorological Observatory were analysed to determine their relation to wind gustiness, defined according to the criteria used at Brookhaven National Laboratory. The relation between wind gustiness and wind speed and direction was analysed, together with the annual and monthly variation. The relation between the concentration of sulphur dioxide and wind gustiness was also investigated, and proved to be a very useful indicator in this kind of analysis, especially in local studies.
Distribution and projections of nitric oxide synthase neurons in the rodent superior olivary complex.
2000
The superior olivary complex (SOC), a group of interrelated brainstem nuclei, sends efferents to a variety of neuronal structures including the cochlea and the inferior colliculus. The present review describes data obtained from rodents providing evidence that the gaseous, short-living neuroactive substance nitric oxide (NO) is produced in the SOC. The NO-synthesizing enzyme neuronal NO-synthase (nNOS) has been localized by means of several methods including histochemistry and immunohistochemistry. Perikarya containing nNOS were found in several nuclei of the SOC. Their largest numbers and percentages of total cells were observed in the medial nucleus of the trapezoid body. Stained terminal…
Laboratory measurements and astronomical search for the HSO radical
2016
[Context] Despite the fact that many sulfur-bearing molecules, ranging from simple diatomic species up to astronomical complex molecules, have been detected in the interstellar medium, the sulfur chemistry in space is largely unknown and a depletion in the abundance of S-containing species has been observed in the cold, dense interstellar medium. The chemical form of the missing sulfur has yet to be identified.
Intercultural education in italy. Cultural identity, educational emergency and teaching strategies: a mathematics laboratory
2014
The research about the intercultural phenomenon in Italy increased with the growing phenomenon of migration, highlighting the problem of cultural diversity and social policies. "The encounter with the diversity should not be suffered, either tolerated, or rejected it should be accepted as survival strategy" (Callari Galli, 2000). This should go beyond the logic of the social emergency and the perception that people have of the problem. The school has, in this process, a key role. The goal of a good educa-tional project is to understand that the intercultural requires continual reference to the concrete experi-ences of the people Theoretical assumptions of the project are the concepts of “in…
Verifica dell'efficacia didattica di un percorso laboratoriale per l'insegnamento dell'italiano nelle scuole dell'infanzia e primaria
2010
Le attività formative del laboratorio di Didattica della lingua italiana, rivolto a futuri maestri, hanno inteso promuovere buone pratiche di insegnamento linguistico, stimolando la trasformazione delle conoscenze in abilità professionali. Il laboratorio ha inteso offrire agli studenti la possibilità di riflettere e rielaborare, di osservare e sperimentare tecniche operative, di mobilitare risorse per l’analisi, la progettazione e la simulazione di situazioni didattiche e di interventi educativi. La verifica dei risultati, eseguita con strumenti di rilevazione ed autovalutazione delle competenze, e l’esame delle risposte degli studenti sull’efficacia e il gradimento dell’esperienza sottolin…
Inappropriateness in laboratory medicine: an elephant in the room?
2017
Appropriateness of diagnostic testing can be conventionally described as prescription of the right test, using the right method, at the right time, to the right patient, with the right costs and for producing the right outcome. There is ongoing debate about the real burden of inappropriateness in laboratory diagnostics. The media coverage of this issue has also recently led to either over- or under-emphasizing the clinical, organizational and economic consequences. This is quite problematic, inasmuch as some reliable data are available in the current scientific literature, showing that inappropriateness of laboratory testing can be as high as 70%. This is especially evident for, though not …
Co-costruzione dell'apprendimento: dalla pratica riflessiva all'azione. Inquiry-Based Laboratory e action learning nella formazione dei futuri docent…
2022
Il presente lavoro espone gli esiti di una ricerca sperimentale a gruppo unico, condotta con 1350 corsisti e 120 docenti di laboratorio frequentanti il V ciclo del corso di specializzazione per le attività di sostegno didattico per le scuole dell’infanzia, primaria, secondaria di primo e secondo grado dell’Ateneo di Palermo svoltosi nell’A.A. 2020/2021. La cornice teorica all’interno della quale si delinea la ricerca è quella dell’approccio Inquiry-Based Laboratory (IBL), del Reflective Learning e dell’Action Learning, fondamentale per la costruzione di una professionalità docente competente, consapevole e responsabile. Il percorso di ricerca ha applicato il modello dell’IBL alle attività l…
EFFECTIVENESS OF BASALT FIBRE-REINFORCED CEMENTITIOUS SYSTEMS IN CONFINING MASONRY MEMBERS: AN EXPERIMENTAL INVESTIGATION
2020
The use of composites based on fibre-reinforced polymers (FRPs) to strengthen masonry columns has become a common practice in the last decades. FRPs, however, exhibit some shortcomings when applied to masonry substrates, due to the organic nature of their matrix. For this reason, increasing attention is paid today to composites based on fibre-reinforced cementitious matrices (FRCMs), in which the polymeric matrix is replaced with an inorganic matrix (such as cementitious mortars). Cementitious matrices guarantee higher breathability and compatibility with the substrate, less sensitivity to debonding at the interfaces, and higher resistance to fire and high temperatures. Moreover, due to the…
From Solid Spaces To Liquid Spaces: New Ecologies of Musical Practices.
2019
Purpose: In recent years, the interest in creating new educational spaces has increased substantially, aiming to influence the methods of learning of our students and to adopt new educational strategies. This article highlights the importance of the atmosphere when remodeling musical practices. Methodologically, when transforming a space, we do not only have to improve the physical architectures but also the pedagogical ones, as well as keeping the practices consistent with these changes. The MUSICLAB CR-209 'Sound laboratory' have been built in Valencia (Spain). This is a hybrid space designed especially for collaborative projects -teachers, artists, students and researchers- in which soun…
