Variation in mortality among populations is higher for pymetrozine than for imidacloprid and spiromesifen in Trialeurodes vaporariorum in greenhouses…
2014
Abstract. BACKGROUND: Insecticide resistance in Trialeurodes vaporariorum W. is unknown in the species’ northern distribution range where it inhabits mainly commercial greenhouses. Resistance development in whiteflies feeding on year-round crops in greenhouses is possible due to use of chemical treatments to back up biocontrol. We tested the response levels to spiromesifen, pymetrozine and imidacloprid in whiteflies collected from seven greenhouses within a 35 km radius in Western Finland. RESULTS: All except one (PR) population had LC50 values below the recommended concentrations for the tested compounds. However, some populations showed reduced susceptibility to pymetrozine in comparison …
Restoration of a XVII Century’s predella reliquary: From Physico-Chemical Characterization to the Conservation Process
2021
We report on the restoration of a XVII century’s predella reliquary, which is a part of a larger setup that includes a wall reliquary and a wooden crucified Christ, both belonging to the church of “Madre Maria SS. Assunta”, in Polizzi Generosa, Sicily, Italy. The historical/artistic and paleographic research was flanked successfully by the scientific objective characterization of the materials. The scientific approach was relevant in the definition of the steps for the restoration of the artefact. The optical microscopy was used for the identification of the wood species. Electron microscopy and elemental mapping by energy-dispersive X-ray (EDX) was successful in the identification of the l…
« Recyclages audiovisuels dans le documentaire de création contemporain »
2022
La numérisation à grande échelle et la mise en ligne des fonds d’archives filmiques, la prolifération d’images sur internet, notamment depuis l’apparition de YouTube en 2005, ou encore les techniques numériques de traitement des images ont favorisé l’essor des films de found footage –littéralement enregistrements ou images trouvés–, une modalité qui est devenue une tendance marquante du documentaire contemporain. Certaines de ces œuvres, parfois constituées intégralement d’images de « seconde main » (Blümlinger, 2013), au-delà de la reconnaissance critique et de l’intérêt des chercheurs, ont connu le succès en salles ou sur les plateformes et ont été projetées et récompensées dans les festi…
Nascita e sviluppo della ricerca empirica in campo didattico in Italia
2015
Si ritiene che la ricerca didattica in Italia si sia riavviata intorno al 1950 per il contatto con le scuole statunitensi, per la diffusione delle opere di Dewey e per la nascita dell’Istituto Superiore di Pedagogia della congregazione salesiana. Si ricostruisce il periodo pioneristico della ricerca empirica in campo didattico con il contributo di Calonghi e Visalberghi. Si segnalano alcuni eventi significativi che, intorno alla metà degli anni Settanta, contribuirono all’affermazione della Didattica come scienza dell’insegnamento-apprendimento. Si indicano le principali linee di ricerca empirica in Didattica presenti nell’attuale panorama scientifico italiano.
Défis à relever pour la politique budgétaire en Amérique latine en matière de stabilisation et de redistribution
2016
Cet article se propose d'étudier les réponses offertes par la politique fiscale en Amérique latine dans la situation actuelle " d'atterrissage en douceur ". En fait, il apparaît que la région est exposée à un risque de choc externe de pays développés et la Chine à un risque politique. Dans ces conditions, la politique fiscale a un rôle important à jouer pour gérer ces risques en se centrant sur ses fonctions de stabilisation et de distribution. En outre, nous proposons un système de plusieurs mesures pour chaque fonction. Enfin, nous démontrons que les pays latino-américains ne souffrent pas de contrainte du financement pour appliquer nos recommandations.

L’amicizia politica nell’Ottocento: Giuseppe Mazzini e Francesco Crispi
2014
Giuseppe Mazzini and Francesco Crispi were very close friends. Their relationship is a typical case of political friendship in the nineteenth century. The first one was the political teacher and the living icon of Italian republicans. After the Unity, Crispi decided to leave republican side and to support constitutional parliament, even if under monarchy, unlike Mazzini, who wished conspire against the reign. This astonishing choice divided him from his old teacher Mazzini, and this loud breach between two great friends and democrat leaders broke the Left too.
La buona morte di Filippo iv e la proclamazione del suo successore. Un modello di comunicazione in età barocca
2021
Nella prima età moderna, l’importanza attribuita dalla società del tempo al rituale funebre ha portato l’attenzione degli studiosi sulle pratiche funerarie e sugli apparati effimeri commissionati agli artisti di corte, con il susseguirsi di numerosi studi che hanno analizzato il fenomeno sotto vari punti di vista, trovando spesso una contestualizzazione territoriale della produzione effimera, esaminando scrupolosamente le cerimonie funebri della monarchia spagnola: Il trattamento dei corpi, imbalsamazione, l’abito dei monarchi, il tipo di sepoltura, il corteo funebre, le cappelle ardenti o i modi di mostrare il dolore. Un impegno comune inizia ad apparire dalla serie di belle morti, che acc…
The most important Roman cities in Valencian Land until the 3rd century
2011
The region of Valencia is the geographic link between southern and northern Mediterranean Iberia, between the Betis Valley and the islands of Ibiza and Formentera. Its strategic location is the reason behind the early Romanisation of Saguntum, Valentia and Ilici. They were neither large cities nor had costly monuments compared to Hispania as a whole; however, their interest lies in the fact that they display a model of integration into Roman lifestyles that preserves some traits from the local past, as can be gleaned from their reputation (see Sagunt) or their epithets (Valentia Edetanorum).
Bartomeu de Tresbens, physician and astrologer in the service of king Peter the Ceremonious and the infant John: between the service to the Crown and…
2018
Bartomeu de Tresbens was a physician, astrologer and philosopher at the service of two kings of the Crown of Aragon, Peter IV the Ceremonious and his son, Duke John, the future John I the Hunter, between 1360 and 1375, approximately. His major work of astrological content has hardly been studied, except for the Llibre de les nativitats (Book of Nativities). Similarly, most of his biography is not known. The documents, which are mainly the correspondence of its relationship with the monarchy, are preserved, but also other records that connect him to the municipalities of Barcelona and Cervera. Particularly in the latter case, Tresbens was tempted by the municipal authorities for being the ph…
