Experimental observations of upstream overdeepening

2005

The issue of morphodynamic influence in meandering streams is investigated through a series of laboratory experiments on curved and straight flumes. Both qualitative and quantitative observations confirm the suitability of the recent theoretical developments (Zolezzi & Seminara 2001) that indicate the occurrence of two distinct regimes of morphodynamic influence, depending on the value of the width ratio of the channel β. The threshold value βR separating the upstream from the downstream influence regimes coincides with the resonant value discovered by Blondeaux & Seminara (1985). Indeed it is observed that upstream influence may occur only in relatively wide channels, while narrower stream…

BedformMechanics of MaterialsMechanical EngineeringOverdeepeningThe issue of morphodynamic influence in meandering streams is investigated through a series of laboratory experiments on curved and straight flumes. Both qualitative and quantitative observations confirm the suitability of the recent theoretical developments (Zolezzi & Seminara 2001) that indicate the occurrence of two distinct regimes of morphodynamic influence depending on the value of the width ratio of the channel β. The threshold value βR separating the upstream from the downstream influence regimes coincides with the resonant value discovered by Blondeaux & Seminara (1985). Indeed it is observed that upstream influence may occur only in relatively wide channels while narrower streams are dominated by downstream influence. A series of experiments has been carried out in order to check the above theoretical predictions and show for the first time evidence of the occurrence of upstream overdeepening. Two different sets of experiments have been designed where a discontinuity in channel geometry was present such that the channel morphodynamics was influenced in the upstream direction under super-resonant conditions (β >βR) and in the downstream direction under sub-resonant conditions (β <βR). Experimental results give qualitative and quantitative support to the theoretical predictions and allow us to clarify the limits of the linear analysis.MechanicsLinear analysisCondensed Matter PhysicsWidth ratioGeology

Addressing Student Motivation, Self-regulation, and Engagement in Flipped Classroom to Decrease Boredom

2016

The interplay teacher regulation and student self- regulation of learning is an important topic in contemporary theories of teaching and learning. The pervasiveness of the boredom experienced by many students, along with its deleterious effects, clearly implies that educators, and teachers responsible for the design of academic settings should pay more attention to this emotion. With regard to the prevention or reduction of boredom, the present findings suggest that specific measures could focus on increasing the perceived values of activities in achievement settings. This study used mixed methodologies, including a student perception inventory and observations, to investigate whether teach…

The Flipped Classroom: a Way to Decrease Boredom and Encourage Student Motivation. La classe capovolta: un modo per diminuire la noia ed incoraggiare…

2016

Recenti studi hanno mostrato l'effetto della noia sul successo. L'esperienza della noia vissuta da molti studenti, insieme con i suoi effetti deleteri, implica chiaramente che educatori ed insegnanti, in quanto responsabili della progettazione di ambienti di apprendimento, prestino maggiore attenzione a questa emozione. Questo contributo intende esaminare l'impatto del modello di insegnamento capovolto sul processo di apprendimento dello studente. Nella ricerca sono state utilizzate differenti metodologie, tra cui un inventario sulla percezione degli studenti e l'osservazione delle pratiche di insegnamento, per indagare se ed in che modo gli insegnanti riescono a gestire la noia in modo div…

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…

Settore L-ART/08 - EtnomusicologiaFirst evidences of frame drums in Sicily trace back to the V century b.C. Tambourines have been recorded until today by paintings archive documentation observations provided by foreign travellers folkloric literature and quite widely by modern ethnomusicology through audio and video recordings collected on the field. Morphology performance techniques repertoires decorations and social use of tambourines in Sicily refer to the wider context of Italian (central-southern part) and Mediteranean area but with some peculiarities chiefly referring to performance skills. Though similar to the techniques practised in other Italian regions in Sicily we can observe a typical style that can be connected with a common historical background with the Arabic-Islamic world.

Charles Darwin and the Origin of Life

2009

When Charles Darwin published The Origin of Species 150 years ago he consciously avoided discussing the origin of life. However, analysis of some other texts written by Darwin, and of the correspondence he exchanged with friends and colleagues demonstrates that he took for granted the possibility of a natural emergence of the first life forms. As shown by notes from the pages he excised from his private notebooks, as early as 1837 Darwin was convinced that “the intimate relation of Life with laws of chemical combination, & the universality of latter render spontaneous generation not improbable”. Like many of his contemporaries, Darwin rejected the idea that putrefaction of preexisting organ…

A Use Case of Data Integration in Food Production

2018

International audience; This paper presents a use case about knowledge representation and integration of data from different domains in food science. An ontology named PO 2 DG, the Process and Observation Ontology for the production of Dairy Gels, has been designed in order to provide a shared vocabulary for domain experts. The available data have been semantically structured using PO 2 DG and are stored in an RDF repository named PO 2 DG dataset. This use case identifies some of the challenges when dealing with a multi domain representation problem, gives some hints about possible solutions and suggests some further work.
