Llengua i espiritualitat en la Vita Christi d’Isabel de Villena
2015
Resum:La Vita Christi de sor Isabel de Villena es gestà en la dècada dels 60 del segle XV a partir dels tractats que l’abadessa del monestir de la Trinitat de València usava per a formar les seues monges i per a suscitar en elles la contemplació de Jesús a través dels ulls de Maria i de les dones que l’envoltaren. La comparació de la llengua i de l’estil del Tractat de la Passió i els de les edicions de 1497 i 1513 ha permès comprovar que aquells s’adaptaren a la sensibilitat religiosa i lingüística de cada moment. El llenguatge de l’abadessa, culte i popular alhora, no es deixà influir pel de Corella. Tanmateix, sor Aldonça de Montsoriu, l’editora de l’incunable, intentà 'vendre' l’«elegan…
Antioxidant Potential of Extracts Obtained from Macro- (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata) and Micro-Algae (Chlorella v…
2018
Background: Natural antioxidants, which can replace synthetic ones due to their potential implications for health problems in children, have gained significant popularity. Therefore, the antioxidant potential of extracts obtained from three brown macroalgae (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata) and two microalgae (Chlorella vulgaris and Spirulina platensis) using ultrasound-extraction as an innovative and green approach was evaluated. Methods: Algal extracts were obtained by ultrasound-assisted extraction using water/ethanol (50:50, v:v) as the extraction solvent. The different extracts were compared based on their antioxidant potential, measuring the extraction …
Catalytic Conversion of Glucose and Chlorella sp. into Furans in the Presence of Niobium Oxide
2023
A series of Nb2O5 solid catalysts have been prepared to be used for the catalytic dehydration of glucose and sugars from algae Chlorella sp. into added value furans. The glucose transformation gave rise to 5-hydroxymethylfurfural (5-HMF). Chlorella sp. was used in the same catalytic conditions to be valorised to furans. By preliminary studies we concluded that the algae aqueous suspension needed a previous treatment in the presence of SiO2 pellets to liberate the carbohydrates that in the catalytic reaction in the presence of Nb2O5 materials gave rise 5-HMF and furfural. The best operative conditions and Nb2O5 catalysts were individuated. The most performant Nb2O5 catalyst also showed an ex…
Prejudicis i censures en la filologia catalana medieval
2014
A la vista de diverses publicacions recents, en les quals se citen treballs meus de forma incompleta i tergiversada, em veig en l’obligació d’esmenar les errades i de donar nous arguments a favor de la meua hipòtesi sobre la producció literària de Joan Roís de Corella. Aquest article, així com d’altres anteriors, s’inscriu en l’àmbit acadèmic de la recerca, en el qual sempre he estat un investigador curós i independent, sense negligir els aspectes que puguen considerar-se polèmics. In view of several recent publications, in which there are mentioned my works in a incomplete and distorted way, I feel obliged to correct the mistakes and also provide new arguments in favor of my hypothesis on …
Kinetic of the Sewage Treatment: The Consumption of Organic Carbon of The Microalga Chlorella sp
2023
As well known, microalgae are eukaryotic or procaryotic microorganisms able to photosynthesize, namely transforming inorganic substrates and sun light into organic compounds and chemical energy. They result very promising in treating civil wastewaters thanks to their ability to employ nitrates and phosphates as nutrients (Lima et al., 2019). Autotrophic microalgae are, anyway, not useful in decreasing the organic carbon content of wastewaters, and for this reason, they cooperate with heterotrophic bacteria. The usefulness of microalgaebacteria consortia in treating wastewaters and the ratio of their inoculum was investigated in a previous work (Lima, 2022a). Contrarily to autotrophic microa…
