La poesia en la prosa de Joan Roís de Corella : delimitació i transmissió del corpus
2019
Resum: L’obra en prosa de Joan Roís de Corella es caracteritza per incorporar-hi poesies. En aquest sentit, aquest treball té un doble objectiu, que es marca des del seu títol: d’una banda, delimita el corpus, que arriba a catalogar vint-i-un poemes, d’una extensió molt diversa, des d’un sol vers fins a vint-i-vuit; d’una altra banda, estudia la transmissió textual d’aquests poemes, amb especial atenció als trets que caracteritzen els diferents testimonis i a les particularitats de transmissió dels poemes.Paraules clau: Joan Roís de Corella, poesia, transmissió textual, corpus, codicologia.Abstract: The work in prose by Joan Roís de Corella is characterized by the incorporation of poetry.

Amores humanos, amores divinos. La Vita Christi de sor Isabel de Villena
2014
La Vita Christi de Sor Isabel de Villena es un texto de enorme relevancia escrito en la Edad Media. Basado en la Vita Christi de Ludolfo de Sajonia, el Cartujano, puede en realidad interpretarse como una Vita Mariae, pues en él se presta atención particular al papel de la Virgen en la vida de Cristo. Este artículo analiza los paralelos entre esta obra y las prosas mitológicas de Joan Roís de Corella. En los dos puede verse un interés en temas amorosos y en la descripción de los afectos y el mundo interior emocional de los personajes. The Vita Christi by Sor Isabel de Villena is a paramount text written in medieval Iberia. Based on the Vita Christi by Ludolf of Saxony (the Carthusian), the w…
Lamentos al son del arpa. La imagen del rey David penitente en la pintura valenciana del Barroco
2015
Este artículo parte de dos lienzos de Pablo Pontons y Vicente Guilló para el estudio de la imagen del rey David, especialmente en su tipo iconográfico de David penitente. Formulado originalmente en las miniaturas medievales que se apoyaban en su papel de salmista y fundador de la música sacra, esta tipología tomó episodios de su vida que se convirtieron en modelos de penitencia. El trabajo estudia la tradición cultural convencionalizada de la gura de David, su patronazgo musical y la continuidad del tipo del rey penitente en el Barroco, tanto en grabados como en programas visuales como los de Pontons y Guilló para Morella y Alcalà de Xivert, respectivamente. Este uso didáctico per…
Short and long-term experiments on the effect of sulphide on microalgae cultivation in tertiary sewage treatment.
2017
[EN] Microalgae cultivation appears to be a promising technology for treating nutrient-rich effluents from anaerobic membrane bioreactors, as microalgae are able to consume nutrients from sewage without an organic carbon source, although the sulphide formed during the anaerobic treatment does have negative effects on microalgae growth. Short and long-term experiments were carried out on the effects of sulphide on a mixed microalgae culture. The short-term experiments showed that the oxygen production rate (OPR) dropped as sulphide concentration increased: a concentration of 5 mg S L¿1 reduced OPR by 43%, while a concentration of 50 mg S L¿1 came close to completely inhibiting microalgae gro…
Production of microalgal external organic matter in a Chlorella-dominated culture: influence of temperature and stress factors
2020
[EN] Although microalgae are recognised to release external organic matter (EOM), little is known about this phenomenon in microalgae cultivation systems, especially on a large scale. A study on the effect of microalgae-stressing factors such as temperature, nutrient limitation and ammonium oxidising bacteria (AOB) competition in EOM production by microalgae was carried out. The results showed non-statistically significant differences in EOM production at constant temperatures of 25, 30 and 35 degrees C. However, when the temperature was raised from 25 to 35 degrees C for 4 h a day, polysaccharide production increased significantly, indicating microalgae stress. Nutrient limitation also see…
Wastewater nutrient removal in a mixed microalgae-bacteria culture: effect of light and temperature on the microalgae-bacteria competition.
2018
[EN] The aim of this study was to evaluate the effect of light intensity and temperature on nutrient removal and biomass productivity in a microalgae¿bacteria culture and their effects on the microalgae¿bacteria competition. Three experiments were carried out at constant temperature and various light intensities: 40, 85 and 125¿µE¿m¿2¿s¿1. Other two experiments were carried out at variable temperatures: 23¿±¿2°C and 28¿±¿2°C at light intensity of 85 and 125¿µE¿m¿2¿s¿1, respectively. The photobioreactor was fed by the effluent from an anaerobic membrane bioreactor. High nitrogen and phosphorus removal efficiencies (about 99%) were achieved under the following operating conditions: 85¿125¿µE¿…
Selecting the most suitable microalgae species to treat the effluent from an anaerobic membrane bioreactor.
2018
[EN] Conventional treatments for nutrient removal in wastewater are shifting to Anaerobic Membrane Bioreactors, which produce a high-quality effluent with minimum sludge production. The effluent resulting contains high nitrogen and phosphorus load that can be eliminated by microalgae culture. The aim of this study is to evaluate the ammonium and phosphorus removal rate of different microalgae species in the effluent of an anaerobic treatment. For that, 4 different microalgae species have been tested (Chlamydomonas reinhardtii, Scenedesmus obliquus, Chlorella vulgaris and Monoraphidium braunii) in batch monoculture and mixed conditions. Results indicate that all species are able to eliminate…
Suspension feeding of anuran larvae at low concentrations of Chlorella algae (Amphibia, Anura).
1990
Ingestion and filtering rates in larval Xenopus laevis, Bufo calamita, Rana temporia and Bufo bufo fed suspensions of Chlorella fusca were investigated. Concentrations were measured with a Coulter Counter. (1) For all species, filtration occurred at concentrations far below those reported by other authors for Rana sylvatica feeding on Chlorella pyrenoidosa. For Bufo bufo, only larvae near metamorphosis showed ingestion at low particle concentrations. Since buccopharyngeal ventilation continues even in the absence of food particles, this threshold feeding behaviour in the younger larvae must be due to different mechanisms to those found in Daphnia and Calanus studied by other authors: probab…
First Nearctic Record of Hydrellia albilabris (Meigen) (Diptera: Ephydridae), a Leafminer of Duckweed (Araceae: Lemnoideae), with Comments on Related…
2019
Hydrellia albilabris (Meigen) (Diptera: Ephydridae) is recorded in the Nearctic Region for the first time. Its biology and immature stages are documented, and other miners in duckweeds (Araceae: Lemnoideae) are discussed. One new combination is proposed: Hydrellia jinpingensis (Zhang, Yang, and Hayashi) is transferred from Cavatorella.
Plausibilitat d?un ancestre comú entre les obres mitològiques de Joan Roís de Corella i les Transformacions de Francesc Alegre
2020
Between the Transformacions of Francesc Alegre (c.1452 - c.1508) and the mythological proses of Joan Roís de Corella some textual coincidences have been detected. Not without reservations, these coincidences have been explained as Corellas influence on Alegre. This is the most satisfactory explanation, given Alegre’s admiration and imitation of Corella’s prose, and Corella’s huge fame in the second half of the fifteenth century. However, Alegre knew earlier versions of Ovid’s Metamorphoses, such as that by Francesc de Pinós (1416-1475), or the anonymous Castilian version, both nowadays lost. And perhaps these versions were known by Corella too. The textual coincidences of these two authors …
