Scour on Alluvial Bed Downstream of Grade-Control Structures
2004
This paper describes an approach for predicting local scour downstream of grade control structures. The developed analysis applies the incomplete self-similarity (ISS) theory for deducing some physically based dimensionless groups controlling the geometrical pattern of the scour profile. The scour measurements available in the literature in conjunction with numerous unpublished data allow a multiregressive calibration of the ISS relationships. The experimental sample includes different bed grain-size distributions and scales of the erosive phenomenon. The results prove that the ratio between the upstream water head and the weir height is able to explain the measurements of scour depth carri…
Thermodynamics of a Phase-Driven Proximity Josephson Junction
2019
We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction {in the short limit}. Owing to the proximity effect, such a junction constitutes a thermodynamic system where {phase difference}, supercurrent, temperature and entropy are thermodynamical variables connected by equations of state. These allow conceiving quasi-static processes that we characterize in terms of heat and work exchanged. Finally, we combine such processes to construct a Josephson-based Otto and Stirling cycles. We study the related performance in both engine and refrigerator operating mode.
Seasonal changes in glacial polynya activity inferred from Weddell Sea varves
2013
Abstract. The Weddell Sea and the associated Filchner–Rønne Ice Shelf constitute key regions for global bottom-water production today. However, little is known about bottom-water production under different climate and ice-sheet conditions. Therefore, we studied core PS1795, which consists primarily of fine-grained siliciclastic varves that were deposited on contourite ridges in the southeastern Weddell Sea during the Last Glacial Maximum (LGM). We conducted high-resolution X-ray fluorescence (XRF) analysis and grain-size measurements with the RADIUS tool (Seelos and Sirocko, 2005) using thin sections to characterize the two seasonal components of the varves at sub-mm resolution to distingui…
Immunomorphological differential diagnosis of maxillary cystic lesions with keratinization
2011
Objetivos: Los quistes maxilares con queratinización son formas lesionales de carácter controvertido y de relevancia clínica, dada la implicación clínico-evolutiva del llamado tumor odontogénico queratoquístico (TOQ). En el presente estudio nos planteamos valorar la utilidad de las técnicas inmunohistoquímicas en la identificación de estas lesiones. Material y métodos: Se analizan de forma retrospectiva las lesiones quísticas maxilares dotadas de fenómenos de queratinización interna, diagnosticadas en un mismo centro hospitalario, a lo largo de un periodo de 4 años, realizando un estudio inmunohistoquímico mediante la aplicación de un panel de cinco anticuerpos (Ki67, Bcl-2, p53, CK19, D2-4…
'A Net of Words: Old English net and max'
2008
Il saggio prende in esame tutte le occorrenze di due parole dell’antico inglese, col significato di ‘rete’, net e max. Numerose sono le occorrenze di net e dei suoi composti; la voce, di origine ie, ricorre in tutte le lingue germaniche antiche. La voce max ha invece un numero limitato di occorrenze ed è priva di confronti diretti in ambito germanico. Ricorre tre volte in antico inglese, tutte nel Colloquio di Ælfric. Si studiano anche gli altri termini per ‘rete’ in antico inglese, le loro accezioni e le loro continuazioni in medio inglese. Il saggio è compreso un volume in onore di Tette Hofstra, già professore ordinario di germanistica, ora emerito, presso l’Università di Groningen, al q…
OPTIMIZING STOCHASTIC SUSCEPTIBILITY MODELLING FOR DEBRIS FLOW LANDSLIDES: MODEL EXPORTATION, STATISTICAL TECHNIQUES COMPARISON AND USE OF REMOTE SEN…
Il presente lavoro di ricerca è stato sviluppato al fine di approfondire approcci metodologici nell'ambito della sucscettibilità da frana. In particolare, il tema centrale della ricerca è rappresentato dal tema specifico dell'esportazione spaziale di modelli di suscettibilità nell'area mediterranea. All'interno del topic specifico dell'esportazione di modelli predittivi spaziali sono state approfondite tematiche relative all'utilizzo di differenti algoritmi o di differenti sorgenti, derivate da DEM o da coperture satellitari. The present work has been developed in order to enhance current methodological approaches within the big picture of the landslide susceptibility. In particular, the ce…
Large-sized pleomorphic adenoma of the cheek treated with Nd:Yag laser: Report of a case and review of the literature
2020
Pleomorphic adenoma (PA) mostly involves parotid glands, while extra-parotid localizations are relatively uncommon. Particularly, PAs of the cheek minor salivary glands with a size larger than 4 cm are exceedingly rare, with only few cases reported. Surgical treatment of PA usually consists in radical excision. However, despite a presumptive radicality, recurrences, sometimes followed by malignant transformation, may occur. Here we report a case of a large-sized (6 cm) PA of the cheek minor salivary glands in a 70 year-old female patient, successfully treated through a conservative approach, based on the use of Nd:YAG Laser (λ=1064 nm). No recurrences were observed after a 2-year follow-up.…
Pattern and rate of post-20 ka verticaltectonic motion around Capo Vaticanopromontory (W Calabria, Italy) based onoffshore geomorphological indicators
2013
The magnitude and rate of Late Pleistocene – Holocene vertical tectonic movements offshore Capo Vaticano (western Calabria) have been quantified on the basis of the depths of infralittoral prograding wedges (IPWs) and associated abrasion platforms formed during the stillstand of the Last Glacial Maximum (LGM). These features were identified on high-resolution reflection seismic profiles acquired along the continental shelf and upper slope around the promontory. The pattern of vertical movements of the Capo Vaticano promontory is characterized by a marked asymmetry associated with a NE-directed tilt. Removal of the non tectonic component of vertical changes using an ice-volume equivalent eus…
Measuring magnitude and rate of vertical movements in the offshore Capo Vaticano (W Calabria) using lowstand coastal prisms and wave-built terraces
2012
The magnitude and rate of vertical movements have been measured in the offshore Capo Vaticano (western Calabria) for the Late Pleistocene - Holocene on the basis of the depth of submerged coastal prism and associated wave-built terrace formed during the sea-level lowstand of the Last Glacial Maximum (LGM). Uplifted and submerged terraces have proved to be valuable recorders of vertical motion in many locations around the world (e.g. DICKINSON, 2001; WEBSTER et alii, 2004) as the depth of their tops appear to be controlled by the sea-level. In the eastern Tyrrhenian margins, depending on the hydraulic energy conditions (i.e. waves and wind-induced currents), the average water depth of terrac…
The Association between Cardiorespiratory Fitness and Gut Microbiota Composition in Premenopausal Women
2017
Abstract The aim of this study was to investigate the association between cardiorespiratory fitness and gut microbiota composition in premenopausal women. The participants consisted of 71 premenopausal Finnish women (aged 19–49 years). Gut microbiota were analyzed using flow cytometry, 16S rRNA gene hybridization and DNA-staining. Maximum oxygen uptake (VO₂ₘₐₓ) was assessed by respiratory gas analyzer and body composition by Bioimpdance. We found that participants with low VO₂ₘₐₓ had lower Bacteroides, but higher Eubacterium rectale-Clostridium coccoides than the high VO₂ₘₐₓ group (p < 0.05 for all). VO₂ₘₐₓ was inversely associated with EreC (r = −0.309, p = 0.01) but not with other bact…
