Guillem Godi, "Si·l gen cors d’estieu es remas" (BdT 219.1)
2018
This article offers a new edition, based on Occitan Chansonnier R, of the canso-sirventes Si·l gen cors d’estieu es remas by the troubadour Guillem Godi. Moving from a textual and documentary analysis, as well as a material-philological perspective, the lectura proposes a later date for the composition (late 13th - early 14th century); moreover, a possible identification of the author with the cardinal Guillem de Peire Godin (1260-1336) is cautiously suggested.

Studies on DNA interaction of organotin(IV) complexes of meso-tetra(4-sulfonatophenyl)porphine that show cellular activity.
2016
PubMedID: 27393277 The interaction of the diorgano- and triorganotin(IV) derivatives of meso-tetra-(4-sulfonatophenyl)porphine (Me2Sn)2TPPS, (Bu2Sn)2TPPS, (Me3Sn)4TPPS and (Bu3Sn)4TPPS to natural DNA was analysed (together with free meso-tetra-(4-sulfonatophenyl)porphine (TPPS4 -) for comparison purposes). Particular attention was paid to (Bu3Sn)4TPPS, a species that shows significant cellular action. Preliminary tests were done on the solution properties of the organotin(IV) compounds (pKA and possible self-aggregation). Spectrophotometric and spectrofluorometric experiments showed that all the investigated organotin(IV) derivatives strongly interact with DNA, the binding energy depending …
El componente pragmático en los diccionarios: Implicaciones para la Lexicografía
2015
Dictionaries are a list of words, simple or complex, that are treated as entries (lexical items). It is usual to assert several components: the lemma or headword, named after its most neutral form, followed by an indication of the main inflections of its category: genre and number if they are names, syntactic class if they are verbs. Sometimes, indications of it are made in other aspects: etymology, pronunciation, marks of placement, area of use, register, frequency of use, etc.Among all the group, it is pointed out an area that grows daily, painstakingly, in lexicographic works: the pragmatic component. Most of the words are referential (names, verbs, adverbs), but others correspond to lan…
ICT and tourism impacts in islands
2018
New technologies can represent, for some aspects, both a problem and a precious resource. As we concerns, in tourism sector, ICT can help in managing and promoting destinations in a better way than in the past, especially in those cases where problems linked with the management of tourist flows and the need to manage a sustainable development exists. Monitoring tourism impact at the destination is a fundamental issue in order to respect the right pressure and to avoid negative effects in the destination and with the residents. There are several devices available and useful for different needs, therefore almost each kind of monitoring and analysis can be supported by the right tools. This kn…
Nickel induces intracellular calcium mobilization and pathophysiological responses in human cultured airway epithelial cells.
2009
Abstract Environmental exposure to nickel is associated to respiratory disorders and potential toxicity in the lung but molecular mechanisms remain incompletely explored. The extracellular Ca 2+ -sensing receptor (CaSR) is widely distributed and may be activated by divalent cations. In this study, we investigated the presence of CaSR in human cultured airway epithelial cells and its activation by nickel. Nickel transiently increased intracellular calcium (−log EC 50 = 4.67 ± 0.06) in A549 and human bronchial epithelial cells as measured by epifluorescence microscopy. Nickel (20 μM)-induced calcium responses were reduced after thapsigargin or ryanodine exposure but not by Ca 2+ -free medium…
Impacts of oak deforestation and rainfed cultivation on soil redistribution processes across hillslopes using 137Cs techniques
2021
Abstract Background As one of the main components of land-use change, deforestation is considered the greatest threat to global environmental diversity with possible irreversible environmental consequences. Specifically, one example could be the impacts of land-use changes from oak forests into agricultural ecosystems, which may have detrimental impacts on soil mobilization across hillslopes. However, to date, scarce studies are assessing these impacts at different slope positions and soil depths, shedding light on key geomorphological processes. Methods In this research, the Caesium-137 (137Cs) technique was applied to evaluate soil redistribution and soil erosion rates due to the effects …
What is a tree in the Mediterranean Basin hotspot? A critical analysis
2019
Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…
Guillem Peire de Cazals. D’una leu chanso ai cor que m’entremeta (BdT 227.8)
2016
L’articolo propone una nuova edizione critica di D’una leu chanso ai cor que m’entremeta di Guillem Peire de Cazals, accompagnata da un commento volto a contestualizzare la canzone entro la modalità poetica della mala canso. Il testo, una vera e propria ‘canzone di disamore’, è databile agli anni 1229-1230 e costituisce un cambiamento di rotta da parte del trovatore caorsino, sia sul piano tematico che sul piano stilistico. Il riflesso di tale cambiamento è ravvisabile fin dal binomio incipitale, leu chanso – che si carica di un particolare sovrasenso retorico –, e prosegue nel corso del récit, dove si rintraccia l’uso di un vocabolario e di temi tipici della ‘modalità’ del disamore. This a…
Fenología de los bracónidos (hymenoptera, ichneumonoidea, braconidae) del pirineo andorrano
2006
Phenology of the Braconidae (Hymenoptera, Ichneumonoidea) at Andorra has been conducted/studied using a Malaise trap after a one-year cycle during 1993. A total of 1.892 specimens, representing 23 subfamilies and 79 genera were sampled. About 93.7% of the captures were koinobiont braconids, whereas 6.3% belonged to idiobiont braconids. The annual phenology has been characterized through the correlation between the evolution of the collected braconids and the weather (meteorological conditions). The maximum of the populations were registered between the two rain periods. In fact, the family Braconidae shows an abundance peak from middle of May to end of August, due to the xerothermic conditi…
