Observations of molecular hydrogen mixing ratio and stable isotopic composition at the Cabauw tall tower in the Netherlands
2016
AbstractMeasurements of the stable isotopic composition (δD(H2) or δD) of atmospheric molecular hydrogen (H2) are a useful addition to mixing ratio (χ(H2)) measurements for understanding the atmospheric H2 cycle. δD datasets published so far consist mostly of observations at background locations. We complement these with observations from the Cabauw tall tower at the CESAR site, situated in a densely populated region of the Netherlands. Our measurements show a large anthropogenic influence on the local H2 cycle, with frequently occurring pollution events that are characterized by χ(H2) values that reach up to ≈1 ppm and low δD values. An isotopic source signature analysis yields an apparent…
A K s -band-selected catalogue of objects in the ALHAMBRA survey
2016
The original ALHAMBRA catalogue contained over 400 000 galaxies selected using a synthetic F814W image, to the magnitude limit AB(F814W) ≈ 24.5. Given the photometric redshift depth of the ALHAMBRA multiband data (〈 z〉 = 0.86) and the approximately I-band selection, there is a noticeable bias against red objects at moderate redshift.We avoid this bias by creating a new catalogue selected in the Ks band. This newly obtained catalogue is certainly shallower in terms of apparent magnitude, but deeper in terms of redshift, with a significant population of red objects at z > 1. We select objects using the Ks band images, which reach an approximate AB magnitude limit Ks ≈ 22. We generate masks an…
NEW IMPORTANT STOP-OVER SITES FOR RUDDY SHELDUCK TADORNA FERRUGINEA PALLAS, 1764 (AVES, ANATIDAE) IN SICILY
2018
The Ruddy Shelduck Tadorna ferruginea PALLAS, 1764 is a species widely distributed in Southeast Europe and central Asia (MACKINNON et al., 2000). Records in N and W Europe (including Northern Italy) mainly involve escapes from captivity since this species of duck is commonly kept in wildfowl collection, private gardens and parks. Despite this, actually, in Sicily the Ruddy Shelduck is considered an irregular migratory and wintering species and the observations must be attributed to the presence of wild individuals (CORSO, 2005). From 2009 to 2017, 67 observations were collected and compared with those included in the available bibliography (CORSO, 2005). The species was observed in 7 differ…

The relationship between classroom quality and students' engagement in secondary school
2013
Student engagement has been identified as an influential mediator between classroom interactional quality and adolescent learning outcomes. This study examined the relationship between classroom quality and student behavioural engagement in secondary school classrooms. Three dimensions of classroom quality (emotional, organisational and instructional support) and the dimension of student engagement were observed in nine classrooms using the Classroom Assessment Scoring System. Self-ratings of behavioural engagement were provided by 181 Finnish secondary school students along with their teachers’ ratings of classroom-level student engagement. The results showed, first, that there was variati…
Leaf anatomy in Tamarix arborea var. arborea (Tamaricaceae)
2012
Previously unpublished data on the macro- and micro-morphological features of the leaf of Tamarix arborea var. arborea are provided. Clear differences in salt gland localization and type of venations were observed in the investigated species compared to other Tamarix species, thus emphasizing the taxonomic value of the leaf within this genus.
Analysis of the XMM-Newton observations of IC443
2017
We analyze for the first time the full set of archive XMM-Newton EPIC observations of the Galactic Supernova Remnant IC 443. We aim at identifying the contribution of the shocked ejecta and interstellar medium and at the describing the physical and chemical properties of the shocked plasma. We also aim at addressing the presence of overionized plasma and its physical origin. We trace the morphology of Si- and S-rich ejecta with unprecedented spatial resolution, by adopting a novel method to produce maps of equivalent width. We describe in detail the method adopted and the results obtained and present preliminary results of a spatially resolved spectral analysis performed on selected regions…

I tamburi a cornice in Sicilia
2015
Le prime attestazioni della presenza del tamburo a cornice in Sicilia risalgono al V secolo a.C. Lo strumento è poi documentato fino ai giorni nostri attraverso raffigu¬razioni, documenti d’archivio, resoconti di viaggiatori stranieri, testi di interesse folklorico e, piuttosto ampiamente, dalla ricerca etnomusicologica moderna, per mezzo di audio-registrazioni e videofilmati. Morfologia, tecniche esecutive, repertori, decorazioni, contesto d’uso dei tamburelli in Sicilia si inscrivono nel più ampio quadro dell’area italiana (centro-meridionale) e mediterranea, ma con alcune specificità, soprattutto nelle tecniche esecutive. Queste, sebbene affini a quelle impiegate in altre regioni italian…
