Motivi tragici nelle Imagines di Filostrato Maggiore (I 4; 18; 27; II 4; 10; 13; 23; 29; 30).

Grazie all'analisi del rapporto tra il testo delle descrizioni di Filostrato e quello di Seneca tragico, Ovidio e Stazio si ipotizza la presenza nelle Imagines di allusioni ad opere ellenistiche perdute (si fa riferimento a Callimaco e Nicandro) . Inoltre, sulla base di un parallelismo tra II 4 (Ippolito) e un verso delle Rane di Aristofane si rintraccia una citazione dell'Ippolito Velato euripideo. The analysis of the relationship between the Philostratean text and the one of Seneca (only Tragedies), Ovid and Statius confirmed the presence in Philostratus' Imagines of allusions to some Hellenistic lost works (we refer to Callimachus and Nicander) . In addition, thanks to a parallel between…

Seminal plasma biochemistry and spermatozoa characteristics of Atlantic cod (Gadus morhua L.) of wild and cultivated origin

2011

Abstract Our objectives were to compare spermatozoa activity, morphology, and seminal plasma (SP) biochemistry between wild and cultivated Atlantic cod ( Gadus morhua ). Swimming velocities of wild cod spermatozoa were significantly faster than those of cultivated males. Wild males had a significantly larger spermatozoa head area, perimeter, and length, while cultivated males had more circular heads. Total monounsaturated fatty acids and the ratio of n−3/n−6 were significantly higher in sperm from wild males, while total n−6 from cultivated males was significantly higher than the wild males. Significantly higher concentrations of the fatty acids C14:0, C16:1n−7, C18:4n−3, C20:1n−11, C20:1n−…

Development of Antioxidant Protein Extracts from Gilthead Sea Bream (Sparus aurata) Side Streams Assisted by Pressurized Liquid Extraction (PLE)

2021

The pressurized liquid extraction (PLE) technique was used, for the first time, to obtain protein extracts with antioxidant activity from side streams (muscle, heads, viscera, skin, and tailfins) of gilthead sea bream (Sparus aurata) in order to give added value to these underutilized matrices. Extraction conditions previously optimized for sea bass (Dicentrarchus labrax) side streams were applied. Protein recovery percentages were 22% (muscle), 33% (heads), 78% (viscera), 24% (skin), and 26% (tailfins), which represented an increase of 1.2–4.5-fold compared to control samples (extraction by stirring). The SDS-PAGE profiles revealed that PLE-assisted extraction influenced protein molecular …

Temporary organisations in the creation of dynamic capabilities: effects of temporariness on innovative capacity and strategic flexibility

2020

The dynamic capabilities (DCs) of an organisation refer to its ability to integrate and renew existing competences as circumstances may change. Although research has considered various aspects of D...

Determination of the Soret coefficient of magnetic particles in a ferrofluid from the steady and unsteady part of the separation curve

2004

Experiments on the particle separation in a vertical thermodiffusion column are used to investigate the separation (Soret effect) in ferrofluids. The use of a two-sectional column with internal walls of low thermal capacity allows analyzing the initial part of the unsteady separation curves as well as the steady state regime. The Soret coefficient calculated from the measurements of the separation dynamics agrees well with the one found from the steady separation limit reached in long-time experiments especially if the solutal buoyancy is low.

Experimental Investigation on Innovative Stress Sensors for Existing Masonry Structures Monitoring

2023

Historical masonry structures often suffer gradual deterioration that in many cases can compromise the safety levels and the operating conditions of the buildings. In this context, Structural Health Monitoring (SHM) is an effective tool for the prediction of the structural behaviour and the state of conservation of buildings. Although many monitoring systems have recently been proposed, there is a lack of practical application of low-cost systems. This paper presents an experimental study based on the use of two innovative stress sensors—capacitive stress sensor and ceramic stress sensor—for the monitoring of existing masonry elements. In order to reproduce the actual conditions of onsite m…

Ventilation-Perfusion Ratio in Perflubron During Partial Liquid Ventilation

2010

BACKGROUND: Functional magnetic resonance imaging (fMRI) of fluorine-19 allows for the mapping of oxygen partial pressure within perfluorocarbons in the alveolar space (Pao(2)). Theoretically, fMRI-detected Pao(2) can be combined with the Fick principle approach, i.e., a mass balance of oxygen uptake by ventilation and delivery by perfusion, to quantify the ventilation-perfusion ratio (Va/Q) of a lung region: The mixed venous blood and the inspiratory oxygen fraction, which are equal for all lung regions, are measured. In addition, the local expiratory oxygen fraction and the end capillary oxygen content, both of which may differ between the lung regions, are calculated using the fMRI-detec…

Effects of extra-fine inhaled beclomethasone/formoterol on both large and small airways in asthma

2010

Background: Airway inflammation in asthma involves both large and small airways, and the combination of inhaled corticosteroids (ICS) and long acting beta-2 agonists (LABA) is the mainstay of therapy. Available inhaled combinations differ in terms of drug delivery to the lung and the ability to reach small airways. Aim: To evaluate whether treatment with an extra-fine inhaled combination provides additional effects vs a nonextra-fine combination on airway function. Methods: After a 1- to 4-week run-in period, patients with asthma were randomized to a double blind, double dummy, 12-week treatment with either extra-fine beclomethasone/formoterol (BDP/F) 400/24 lg daily or fluticasone propiona…

La démocratie alimentaire comme enjeu de capacitation territoriale : Étude de cas dans le Tournugeois

2023

This article, through a case study from the Plateforme d'Observation des projets et stratégies urbaines (POPSU) program in Tournus, questions the notion of food democracy and its link with territorial capability. The observation and analysis of the dynamics of this participatory research allow us to enrich the concept of food democracy by crossing it with other theoretical perspectives (in particular the capability approach). They also highlight certain conditions for its effectiveness and raise the question of the relationship between food democracy and public policy. Finally, they invite researchers working on these issues to adopt an involved posture.

La formazione iniziale degli insegnanti attraverso la pratica del microteaching.

2014

Le metodologie che fanno uso della videoregistrazione sono sempre più utilizzate nella formazione professionale dei futuri insegnanti. La professionalità del docente richiede oltre alle conoscenze teoriche o disciplinari, la capacità di mobilitare i saperi per organizzare risposte efficaci a problemi complessi e rilevanti e la capacità di riflettere sul proprio agire. È necessario che durante il percorso universitario l’insegnante in formazione acquisisca specifiche competenze e capacità autoriflessive. Questo contributo descrive una metodologia per la creazione di esperienze formative centrate sull’utilizzo della videoregistrazione e per la raccolta di dati sull’effetto del video sull’appr…
