The role of literal meaning during the construction of meaning that goes beyond pure literal composition was investigated by combining cross-modal masked priming and ERPs. This experimental design was chosen to compare two conflicting theoretical positions on this topic. The indirect access account claims that literal aspects are processed first, and additional meaning components are computed only if no satisfactory interpretation is reached. In contrast, the direct access approach argues that figurative aspects can be accessed immediately. We presented metaphors (These lawyers are hyenas, Experiment 1a & 1b) and producer-for-product metonymies (The boy read Boll, Experiment 2a & 2b) with a…

Theoretical Study of the Catalytic Mechanism of DNA-(N4-Cytosine)-Methyltransferase from the Bacterium Proteus vulgaris

2010

In this paper the reaction mechanism for methylation of cytosine at the exocyclic N4 position catalyzed by M.PvuII has been explored by means of hybrid quantum mechanics/molecular mechanics (QM/MM) methods. A reaction model was prepared by placing a single cytosine base in the active site of the enzyme. In this model the exocyclic amino group of the base establishes hydrogen bond interactions with the hydroxyl oxygen atom of Ser53 and the carbonyl oxygen atom of Pro54. The reaction mechanism involves a direct methyl transfer from AdoMet to the N4 atom and a proton transfer from this atom to Ser53, which in turn transfers a proton to Asp96. Different timings for the proton transfers and meth…

Desigualdad social y toma de decisiones en los comunales: El gobierno del mayor canal de riego de España (la Acequia Real del Júcar, Valencia) en el …

2021

espanolHacia 1850 la Acequia Real del Jucar era el mayor sistema comunitario de riego de Espana y se caracterizaba por la fuerte desigualdad social entre los regantes. El articulo analiza los cambios que experimentaron las instituciones para su gobierno en una etapa de profundas transformaciones sociales y politicas en la sociedad espanola, la segunda mitad del siglo XIX. Los organos de gobierno del canal estaban sujetos a una organizacion de tipo jerarquico que comprendia dos grandes niveles: por una parte, estaba la direccion del conjunto del sistema, en la que solo una reducida elite de terratenientes podia intervenir; por otra, habia organos de gestion local que administraban las sucesi…

Nanosponge-C3N4 composites with improved photocatalytic activity for selective partial alcohol oxidation in aqueous suspension

2022

Composites of C3N4 with nanosponges based on β-cyclodextrins containing a 5% w/w of C3N4 were synthesised, physicochemicaly characterised and tested as heterogeneous photocatalysts for the degradation of 4-nitrophenol and for the partial oxidation of 5-hydroxymethyl-2-furfural and veratryl alcohol. The results outline a synergistic effect in terms of conversion and selectivity. The association of the nanosponges with the C3N4 enhances the photocatalytic activity of the semiconductor, possibly due to the local concentration effect occurring on the photocatalyst surface that would involve a concentration into the nanosponge matrix ca. 500 times larger than in the solution bulk. Composites of …

Neuroendocrine neoplasms in the context of inherited tumor syndromes: a reappraisal focused on targeted therapies

2022

Purpose Neuroendocrine neoplasms can occur as part of inherited disorders, usually in the form of well-differentiated, slow-growing tumors (NET). The main predisposing syndromes include: multiple endocrine neoplasias type 1 (MEN1), associated with a large spectrum of gastroenteropancreatic and thoracic NETs, and type 4 (MEN4), associated with a wide tumour spectrum similar to that of MEN1; von Hippel-Lindau syndrome (VHL), tuberous sclerosis (TSC), and neurofibromatosis 1 (NF-1), associated with pancreatic NETs. In the present review, we propose a reappraisal of the genetic basis and clinical features of gastroenteropancreatic and thoracic NETs in the setting of inherited syndromes with a s…

Photoelectrochemical and EPR features of polymeric C 3 N 4 and O-modified C 3 N 4 employed for selective photocatalytic oxidation of alcohols to alde…

2019

Four different C 3 N 4 specimens have been prepared, a bulk one (MCN), a thermally etched (MCN-TE), a solid prepared by hydrothermally treating MCN with H 2 O 2 (MCN-H 2 O 2 ) and a polymeric carbon nitride-hydrogen peroxide adduct (MCN-TE-H 2 O 2 ). The principal aim of this work was to correlate the capability of the prepared material to generate reactive oxygen species (ROS), under irradiation, with their photocatalytic activities in terms of conversion and selectivity for partial oxidation reactions. Photoelectrochemical studies revealed that MCN-TE represented the best material in terms of photoconductivity, whereas MCN-H 2 O 2 was defective and evidenced a poor mobility of carriers. E…

The current study used event-related brain potentials (ERPs) and behavioral measures to examine effects of genre awareness on sentence processing and evaluation. We hypothesized that genre awareness modulates effects of genre-typical manipulations. We manipulated instructions between participants, either specifying a genre (poetry) or not (neutral). Sentences contained genre-typical variations of semantic congruency (congruent/incongruent) and morpho-phonological features (archaic/contemporary inflections). Offline ratings of meaningfulness (n=64/group) showed higher average ratings for semantically incongruent sentences in the poetry vs. neutral condition. ERPs during sentence reading (n=2…

Análisis de las estrategias de encuadre discursivo en la cobertura electoral sobre Vox en los titulares de la prensa española

2020

La presente investigación se basa en el análisis de un corpus de 413 titulares que encabezaron los textos informativos de ocho diarios españoles, durante la cobertura electoral sobre Vox, en el trans curso de los comicios generales celebrados en España en abril de 2019. Siguiendo el modelo desarrollado por Gallardo Paúls (2014; 2021 en prensa), que estudia las categorías pragmáticas de acuer do con el nivel textual, el interactivo y el enunciativo, hemos po dido identificar determinadas estrategias de encuadre discursivo que contribuyen a orientar cognitivamente los titulares de todos los periódicos que conforman nuestro corpus. Si bien la ilocutivi dad representativa fue la mayoritaria en …
