Macedonio Fernandez: Vision Pura e istante eterno
2013
Il complesso percorso che conduce ad uno sguardo puro sui misteri del mondo si può realizzare, secondo Macedonio Fernández, attraverso uno sforzo dissociativo, mirato al raggiungimento di una percezione depurata dalle reminiscenze dell’appercezione. Questo tortuoso processo prende il nome di contemplación. Si tratta di un indagine critica sulla natura delle nostre percezioni, finalizzata alla confutazione delle nozioni dell’Io, della Materia, dello Spazio e del Tempo. Solamente dopo quest’analisi critica si potrà raggiungere lo ‘stato mistico’ che Macedonio definisce «ser el mundo sin sujeto ni objeto» o «la actitud de existir sin el yo». La Visión Pura alla quale Macedonio Fernández aspira…
Evidence of low land surface thermal infrared emissivity in the presence of dry vegetation
2007
International audience; Land surface emissivity in the thermal infrared usually increases when the vegetation amount increases, reaching values that are larger than 0.98. During an experiment in Morocco over dry barley crops, it was found that emissivity may be significantly lower than 0.98 at full cover and that in some situations, it might decrease with increasing amount of vegetation, which was unexpected. Older data acquired in Barrax, Spain, over senescent barley also exhibited emissivity values lower than 0.98. The decrease of emissivity was also observed by means of Simulations done with our land surface emissivity model developed earlier. The main reason for such behavior might be f…
Reviewing the identity of the Maltese Polypodium (Polypodiaceae) – new evidence from morphology and flow cytometry
2020
The first record of Polypodium from Gozo (Maltese Islands) was described as a new endemic taxon, Polypodium vulgare subsp. melitense, based on its unique set of morphological characters. It was treated as a novelty and designated as a subspecies of P. vulgare mainly due to the lack of paraphyses, the presence of 10–16 annular cells, and a mean spore length of 64 μm. The fern was reassessed by us employing a more rigid morphological analysis and the application of flow cytometry. The absence of paraphyses was confirmed, but the number of annular cells (5–11) and the spore length (70–79 μm) differed from the previous study. These and other morphological traits, the phenology (leaf-shedding in…
A new Aphid genus and species (Hemiptera: Aphididae: Macrosiphini) living on ferns in Costa Rica and Mexico
2013
AbstractAphid species colonising ferns belong to the subfamily Aphidinae (Hemiptera: Aphididae) and the majority of these to the tribe Macrosiphini. A new genus in this tribe and its type species: Gibbomyzus pteridophytorumnew genus, new species, are established. Apterous and alate viviparous females are described from specimens collected on Blechnum buchtienii Rosenstock (Blechnaceae) in Costa Rica and on Pteridium aquilinum (Linnaeus) Kuhn (Dennstaedtiaceae) and an unidentified fern in Mexico. The taxonomic validity of the two new taxa is discussed based on morphological and molecular data. Morphologically, the new genus is compared with genera with swollen siphunculi recorded in the New …
“Lugares que tienen una herida que sangra”: las geografías interiores de Fernando Valverde
2018
Fernando Valverde (Granada, 1980) reúne en 2016 su poesía completa hasta la fecha: Viento favorable (1997-2002), Razones para huir de una ciudad con frío (2004), Los ojos del pelícano (2010) y La insistencia del daño (2014). Analizamos aquí la constitución de una peculiar cartografía poética, que cumple un papel axial: conecta territorios y culturas bajo una misma matriz existencial, configurando una geografía interior basada en la apropiación subjetiva de ciudad y naturaleza. Esta conversión del ?lugar? en ?espacio practicado? (Michel De Certeau) se realiza aquí a través de dos dispositivos: el mapa y el viaje. Valverde pone en marcha su poesía con la metáfora del ?andar?: logra la apropia…

A contrastive Analysis of the first Canto of Dante’s Inferno: an Examination of the Translations of Seamus Heaney and Ciaran Carson
2008
The article offers a comparative analysis of two English translations of the first Canto of Dante's Inferno: both produced by Irish authors, the two greatly differ. Specific translation strategies are examined in relation to the authors' distinctive poetic styles.

Water erosion prediction by stochastic and empirical models in the Mediterranean: A case study in Northern Sicily (Italy)
2012
The present thesis aimed to explore the methodological advantages as well as limitations in applying different modelling approaches to predict water soil erosion in Mediterranean environments. The research was accomplished in the central northern part of Sicily (Italy), considering this region to be representative of Mediterranean environmental conditions. In this region soil degradation problems, due to water erosion are becoming more and more serious. Consequently, defining models being able to predict erosion susceptibility and to discriminate environmental factors causing erosion is important to protect soil resources. The prediction of the spatial distribution of soil erosion processes…
