Photosynthesis in Lichen: Light Reactions and Protective Mechanisms
2012
Lichens are symbiotic associations (holobionts) established between fungi (mycobionts) and certain groups of cyanobacteria or unicellular green algae (photobionts). This symbiotic association has been essential in establishing the colonization of terrestrial and consequently dry habitats. About 44 genera of algae and cyanobacteria have been reported as lichen photobionts. Due to the uncertain taxonomy of many of these photobionts, these numbers were considered as approximations only. Ahmadjian (1993) estimates that only 25 genera were typical lichen photobionts. The most common cyanobionts are Nostoc, Scytonema, Stigonema, Gloeocapsa, and Calothrix, in order of frequency (Budel, 1992). Gree…
Stable Green Electroluminescence from an Iridium Tris-Heteroleptic Ionic Complex
2012
An ionic tris-heteroleptic iridium complex gives green light-emitting electrochemical cells (LECs) with unprecedented performances for this part of the visible spectrum. The devices are very bright (>1000 cd m–2), efficient (∼3%), and stable (>55 h). The novel complex is prepared using a new and efficient synthetic procedure. We show that there is a mixed orbital formation originating from the two different orthometalating ligands resulting in photophysical properties that lie between those of its two bis-heteroleptic analogs. Therefore, tris-heteroleptic complexes provide new avenues for fine-tunning the emission properties and to bridge gaps between a series of bis-heteroleptic complexes.

Protocolo técnico para la fotografía de fuentes filológicas primarias
2014
con fines documentales, proyectado para garantizar la máxima fidelidad posible al motivo original representado. Tras una descripción detallada del material necesario, seleccionado específicamente en función de las necesidades particulares de la fotografía de textos manuscritos o impresos, se desarrolla un procedimiento adaptado a las nuevas circunstancias de la fotografía digital, concebido en dos fases: la captación de la imagen en formato RAW, y su posterior edición. En este estudio se trata la primera parte, describiendo sistemáticamente, paso a paso, las decisiones técnicas relativas a los ajustes fotográficos de la toma en diferentes situaciones lumínicas, encaminadas a maximizar la ca…
Translation and terminology. Apropos of two Spanish versions of Dumarsais’ Logique (Madrid, 1800)
2013
Framed in the field of philosophical translation (lato sensu), this article deals with two different versions of Dumarsais’ Logique ([1769] 1797, Paris), both published in Madrid in 1800. We argue that these two Lógicas, which were translated by two different persons, had distinct purposes. This is evidenced by their respective bibliographical contexts and metatexts and by their translators’ use of different sets of Spanish terminological equivalents for the concepts that, as set out in the first few pages of his Logique, are key in Dumarsais’ theory of knowledge. In the first of these translations, which envisions logic as having an introductory role in the acquisition of scientific knowle…
Traduction et terminologie. A propos de deux versions espagnoles (Madrid, 1800) de la Logique de Dumarsais
2013
Cette étude qui relève du domaine de la traduction philosophique (lato sensu) a pour objet deux versions de la Logique de Dumarsais ([1769]1797) éditées en Espagne (1800). Nous montrons que ces deux Lógicas, oeuvres de deux traducteurs différents, qui eurent chacun des fins également différentes, comme le prouvent le contexte bibliographique et les métatextes respectifs, manifestent la présence d’une terminologie espagnole divergente pour les termes clé de la théorie de la connaissance que l’auteur français exposa dans les pages initiales de sa Logique. La première de ces traductions, qui attribue à la logique un rôle d’introduction aux sciences, choisit des termes systématiquement calqués …
OVERTURE Love Love is a Pink Cake or Queering Chopin in Times of Homophobia
2021
An introduction to the three essays included in this section. The article highlights the right to know whether Chopin was gay and contextualizes this inquiry in a very long and pervasive historiographical tradition, essentially twohundred years long, dedicated to examine Chopin sexual orientation, on the one hand, and on the other the more recent tradition of queering western classical music composers. The main point is not to demonstrate categorically that Chopin was ?gay? (a relative, modern identity marker in any case) but rather to highlight the discourses that have presented him as unequivocally heterosexual.
The Effect of Music on Movement Perception: Synchresis in Hits for HIIT
2021
Hits for HIIT consists in a research-creation project aiming to produce both musical pieces and training exercises for, on the one hand, optimizing HIIT practice and, on the other, enriching scholarly research on the relations between music and sports. These questions and their related studies have highlighted music/movement relations and the way they are perceived. In this paper we would like to outline how we attempt to build a two-way dialogue between the production of music adapted to HIIT and the design of workouts based on the music.

Women in Patriotic Societies: A Spanish Debate in a European Context
2022
This chapter examines in its European context the discussions maintained from 1776 to 1787 over the admission of women to the Economic Society of Madrid, one of the patriotic societies founded in the eighteenth century and representative of Enlightened reforming ideals and models of sociability. The debate assumed a wide resonance and was seen by contemporaries as a turning point, opening up no less than a “political revolution. It was connected, to a larger extent than has been acknowledged up to now, to European discussions about the nature of gender difference, women’s education and their access to public spaces (academies, literary, scientific and reforming societies. Taking place in a …
