Base-Controlled Regiospecific Mono-Benzylation/Allylation and Diallylation of 4-Aryl-5-indolyl-1,2,4-triazole-3-thione : Thio-Aza Allyl Rearrangement
2023
The regiospecific S-benzylation/allylation of two 4-aryl-5-indolyl-1,2,4-triazole-3-thione precursors was carried out using Et3N as a base. Allyl group migration from exocyclic sulfur to the triazole nitrogen (N3) was successfully achieved in a short time via thermal fusion without the need for any catalyst. The allylation of indole nitrogen, along with exocyclic sulfur or triazole nitrogen (N3), was carried out using K2CO3 as stronger base. S,N-Diallylated products were converted to N,N-diallylated analogues using a simple fusion approach. Structural analyses of the two newly synthesized hybrids 2b and 5b investigated via the X-ray diffraction of a single crystal combined with Hirshfeld ca…

Sedimentary environment, lithostratigraphy and dating of sediment sequences from Arctic lakes Revvatnet and Svartvatnet in Hornsund, Svalbard
2016
Abstract The sedimentary environment, sediment characteristics and age-depth models of sediment sequences from Arctic lakes Revvatnet and Svartvatnet, located near the Polish Polar Station in Hornsund, southern Svalbard (77°N), were studied with a view to establishing a basis for paleolimnological climate and environmental reconstructions. The results indicate that catchment-to-lake hydroclimatic processes probably affect the transportation, distribution and accumulation of sediments in different parts of lakes Revvatnet and Svartvatnet. Locations with continuous and essentially stable sedimentary environments were found in both lakes between water depths of 9 and 26 m. We used several diff…
Le Dictionnaire de l’Académie française source des dictionnaires bilingues franco-italiens de 1871 à nos jours
2017
L'articolo si propone di sondare l'influenza del Dictionnaire de l'Académie française sulla lessicografia bilingue franco-italiana in un arco cronologico compreso tra il 1871 e il 2000. In particolare, si passano in rassegna le prefazioni dei principali dizionari bilingui pubblicati nel periodo considerato, al fine di valutare se il Dictionnaire de l'Académie venga citato tra le fonti e qual uso il lessicografo intenda farne. The article aims to explore the influence of the Dictionnaire de l'Académie française on French-Italian bilingual lexicography in a chronological arc between 1871 and 2000. In particular, the prefaces of the main bilingual dictionaries published in the period considere…
Josep Melcior Gomis 1791-1836. Possibilitats de resistència i transgressió individual a la biografia d'un compositor valencià. Estudi i anàlisi de la…
2015
Tesi doctoral basada en un projecte interdisciplinari d'investigació on el propòsit de la tesi doctoral és l'estudi biogràfic plural inserit en les noves perspectives historiogràfiques del compositor valencià Josep Melcior Gomis (1791-1836) inserint-lo en el context modernitzador del nou Estat-Liberal però estudiant les capacitats de transgressió i radicalitat que el subjecte i el seu anhel biogràfic té davant del context i la societat. A més, es treballa l'anàlisi de la seva obra creativa, la transcripció de les seves partitures més dels diferents discursos de la música com a element col·lectiu identitari i els seus problemes historiogràfics. A més, la tesi doctoral estudia la identitat na…
The Fight for the Self-Representation. Ainu Imaginary, Ethnicity and Assimilation
2017
Film representation of the Ainu people is as long as cinema but it has not remained stable over time. From the origins of cinema, Ainu people were an object of interest for Japanese and foreign explorers who portrayed them as an “other” savage and isolated from the modern world. The notion of “otherness” was slightly modified during wartime, as the Ainu were represented as other Japanese subjects within the “imperial family” and at the end of the fifties, during which entertainment cinema presented the Ainu according to the western Hollywood code on the one hand; and Mikio Naruse proposed a new portrayal Ainu focusing on the Ainu as a long discriminated social collective rather than as an e…
Mujeres para el cambio : la lucha contra la pobreza en El Salvador y los impactos de la experiencia migratoria en las biografias de las mujeres salva…
2010
El presente estudio realiza un análisis de la pobreza en El Salvador con un enfoque de género y ha sido el resultado de dos fases de investigación, en las cuales se han hecho un análisis de la mujer salvadoreña que vive en el país y de las mujeres que han migrado hacia Italia. En la primera fase de investigación (Mayo 2006- Septiembre 2007) se ha realizado un análisis de la mujer salvadoreña que en el país vive en condición de pobreza, con el objetivo de valorar la importancia de la formación de capital humano femenino y el rol de la cooperación al desarrollo en la cuestión de género. El objetivo general ha sido lo de valorar desde adentro la eficacia o menos de un proyecto de desarrollo lo…
Migración residencial y urbanismo expansivo en el mediterráneo español
2015
Este artículo investiga la migración internacional de jubilados noreuropeos hacia España y su influencia en el desarrollo del urbanismo expansivo en nuestro país. Los temas clave que en este artículo se analizan son la expansión del urbanismo expansivo durante la burbuja inmobiliaria española, la cantidad y distribución de los jubilados noreuropeos residentes en España, y la relación entre la llegada de dichos migrantes residenciales y la difusión del urbanismo expansivo. Este artículo explica los motivos de esta migración residencial, que están principalmente relacionados con el clima y el estilo de vida mediterráneos. También describe los beneficios y los inconvenientes de dicha migración…
Elusive active faults in a low strain rate region (Sicily, Italy): Hints from a multidisciplinary land-to-sea approach
2022
Low Strain Rate regions (LSRrs), i.e., areas undergoing tectonic deformation at rates of 1 mm/yr or less, often host important cities and highly vulnerable anthropogenic assets, and due to their subdued topography and relatively infrequent seismicity, are often considered low seismic hazard areas. Despite this, infrequent but high-magnitude earthquakes in such regions suggest that identifying active structures in the LSRr is one of the primary challenges for both the scientific community and modern societies. In such regions, one of the main issues in identifying active faults is the lack of valuable outcrop data due to erosional/sedimentation rates overwhelming the fault deformation, causi…
PERFORMANCE EVALUATIONS OF 3D WEB-SERVICES AND OPEN-SOURCE SOFTWARE FOR DIGITAL MODELING OF ARCHAEOLOGICAL FINDS
2016
The Structure From Motion (SFM) algorithms derived from Computer Vision community make image-based techniques a competitive and user friendly approach to obtain 3D information of real objects. These algorithms have been implemented in many 3D web-services and open-source software to develop free instruments for the reconstruction of very detailed 3D digital models. Their use is becoming very common above all in archaeological studies but their potentiality for metric application has not been tested at all. The aim of the work is to investigate the quality and the accuracy of 3D models obtained through 3D web-services and SFM open-source software. Different tests have been performed using so…
