Sulla (s)fortuna critica di fra Innocenzo da Petralia Sottana e su un suo inedito Crocifisso
2021
Dopo una premessa sulla produzione scultore francescana in Italia, in particolare in Sicilia, si esamina la storiografia siciliana che, a partire dal XVII secolo, si è occupata della produzione dello scultore Innocenzo da Petralia Sottana (1602/03-1648 circa), frate laico dell’ordine dei Minori Riformati. L’artista, la cui figura è stata adombrata da quella del più noto frate Umile da Petralia Soprana, ha scolpito Crocifissi non solo in Sicilia, ma in altre regioni della penisola, dal Lazio all’Umbria alle Marche. Al nostro, su base documentaria, sono stati ricondotti due opere conservate a Malta. Frate Innocenzo, autore non solo di Crocifissi, ma anche di altri simulacri mariani e agiograf…
Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
The Role of Excited Oxygen Molecules in the Formation of the Secondary Ozone Layer at 87 to 97 km
2018
The secondary ozone layer is located at elevations of 87 to 97 km in the upper mesosphere – lower thermosphere. It overlaps with the ionospheric D-layer. Daytime intensive UV radiation is dissociating O2 molecules to O atoms and photoexcitating O2 molecules up to 11.07eV level. Ozone photolysis between the wavelengths of 118.7–121.6 nm produces three oxygen atoms from one ozone molecule. Collision reactions of O2(B3 Σu —) and O2(X3 Σg —, υ≥26) with O2(X3 Σg —, υ=0) produce additional oxygen atoms. The number of oxygen atoms is maintained at such a high level that a small but significant ozone concentration survives. UV radiation weakens radically during the night. The number of O atoms show…

Linee guida per la valutazione di aziende sequestrate e confiscate alla criminalità organizzata
2020
L'articolo presenta "Le Linee guida per la valutazione di aziende sequestrate e confiscate" alla criminalità organizzata, evidenziando alcuni criteri per guidare la scelta del metodo di valutazione appropriato e suggerendo l'inclusione di una prospettiva di stakeholder negli studi di valutazione aziendale. The article presents "The Guidelines for the business valuation of seized and confiscated firms” from the organized crime, by pointing out some criteria to guide the selection of the appropriate valuation method and suggesting the inclusion of a stakeholder perspective in the business valuation studies.
Linee guida per la valutazione di aziende sequestrate e confiscate
2020
Le linee guida mirano ad analizzare le specificità delle aziende sequestrate e confiscate ai fini del processo di stima del valore di tali delicate realtà aziendali, esaltando in particolare come l’applicazione del metodo valutativo costituisca solo una fase del più ampio processo di stima, che deve necessariamente considerare elementi qualitativi, ma anche quantitativi di difficile ponderazione.
Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application
2021
This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…
Stress sensitivity of stylolite morphology
2009
International audience; Stylolites are rough surfaces that form by localized stress-induced dissolution. Using a set of limestone rock samples collected at different depths from a vertical section in Cirque de Navacelles (France), we study the influence of the lithostatic stress on the stylolites morphology on the basis of a recent morphogenesis model. We measured the roughness of a series of bedding-parallel stylolites and show that their morphology exhibits a scaling invariance with two self-affine scaling regimes separated by a crossover-length (L) at the millimeter scale consistent with previous studies. The importance of the present contribution is to estimate the stylolite formation s…
¿Quién está buscando su mejor versión? Coaching y psicología deportiva en el proceso de terapeutización de (y desde) el golf
2020
This article asks about the expansion of psychological, therapeutic and self-enhancement ethos through the networks and devices that configures middle and upper-middle classes, and about the ways in which this process is singled out starting from the encounter between coaching and psychology paradigms with golf fans, in contemporary Argentina. The empirical materials that support the analysis have been ethnographically produced from the interaction with golf players and coaches.
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
