Elaborazione e validazione di modelli dell’impatto antropico e dei cambiamenti climatici sulle qualità dei suoli in Sicilia, con particolare attenzio…

Il declino della sostanza organica e l’erosione idrica sono due fattori di rischio di degrado del suolo fra i più diffusi in Sicilia. In che misura è possibile contrastarli modificando le attività antropiche ed in particolare quelle in ambito agricolo? Lo scopo della presente ricerca di dottorato è stato quello di mettere a punto dei modelli che permettessero di spiegare le relazioni esistenti fra le azioni dell’uomo in ambito agricolo con la sostanza organica e con l’erosione idrica nei suoli siciliani, tenendo conto anche del clima. Le due indagini sono state svolte separatamente, in parallelo, in aree agricole della Sicilia occidentale per la sostanza organica, sull’intero territorio sic…

An explicit unconditionally stable numerical solution of the advection problem in irrotational flow fields

2004

[1] A new methodology for the Eulerian numerical solution of the advection problem is proposed. The methodology is based on the conservation of both the zero- and the first-order spatial moments inside each element of the computational domain and leads to the solution of several small systems of ordinary differential equations. Since the systems are solved sequentially (one element after the other), the method can be classified as explicit. The proposed methodology has the following properties: (1) it guarantees local and global mass conservation, (2) it is unconditionally stable, and (3) it applies second-order approximation of the concentration and its fluxes inside each element. Limitati…

Sveriges irredenta : försvenskningen av de finskspråkiga i Norrbotten 1888-1921 ur identitetsbyggandets synvinkel

2009

In this study the task is to point out the key features in the making of a Swedish nation from the perspective of a minority language, i.e. the Finnish speaking minority in the region of Norrbotten, Sweden. Swedish historians usually list the fear of Russia (Russia, the arch-enemy -topos) and the Laestadian movement as main reasons for the policy of cultural assimilation of the Finnish-speaking minority. In this study the main task is to use the post modern discourse analysis (especially Michael Shapiro) in reading texts between the years 1888 and 1921. For this purpose I have gone through material of the period, i.e. debates in the Swedish Parliament, the newspaper Haparandabladet, pamflet…

Scientific restoration and historical-artistic research of the Saint Giovanni Battista wooden polychrome gilded high-relief from Saint Barbara church…

2022

Lo scopo della presente ricerca è quello di descrivere i risultati del restauro scientifico supportato dalla ricerca archivistica e dall'analisi storico-artistica, dell'altorilievo ligneo policromo raffigurante San Giovanni Battista della chiesa di Santa Barbara a Naro, Agrigento, Italia, parte di un alterpiece di fine XV - inizi XVI secolo The purpose of the present research is to describe the results of the scientific restoration, supported by archival research and art-historical analysis, of the polychrome wooden high-relief representing St. John the Baptist from the church of Santa Barbara in Naro, Agrigento, Italy, part of a late 15th- to early 16th-century alterpiece
