La portada de la iglesia de las Escuelas Pías de Gandía. Su proceso constructivo y modulación arquitectónico-musical
2020
The facade of the church of the Pious Schools of Gandia has not attracted the attention of researchers. However, its conception has a great architectural culture and constitutes an essential work to understand its context, fundamentally, that of the theoretical treatises of the Renaissance. From this study it is wanted to value its architecture and that it is considered as an outstanding ingredient to know its period of construction in general and jesuit architecture in particular. For its understanding, its interpretation in the culture of contemporary architecture treaties and, especially, in the architectural-musical theory of Leon Battista Alberti will be necessary..

Lower semicontinuity of weak supersolutions to the porous medium equation
2013
Weak supersolutions to the porous medium equation are defined by means of smooth test functions under an integral sign. We show that nonnegative weak supersolutions become lower semicontinuous after redefinition on a set of measure zero. This shows that weak supersolutions belong to a class of supersolutions defined by a comparison principle.
Deoxysarpagine Hydroxylase — A Novel Enzyme Closing a Short Side Pathway of Alkaloid Biosynthesis in Rauvolfia
2002
Microsomal preparations from cell suspension cultures of the Indian plant Rauvolfia serpentina catalyze the hydroxylation of deoxysarpagine under formation of sarpagine. The newly discovered enzyme is dependent on NADPH and oxygen. It can be inhibited by typical cytochrome P450 inhibitors such as cytochrome c, ketoconazole, metyrapone, tetcyclacis and carbon monoxide. The CO-effect is reversible with light (450 nm). The data indicate that deoxysarpagine hydroxylase is a novel cytochrome P450-dependent monooxygenase. A pH optimum of 8.0 and a temperature optimum of 35 degrees C were determined. K(m) values were 25 microM for NADPH and 7.4 microM for deoxysarpagine. Deoxysarpagine hydroxylase…
Gestación por sustitución: Desafíos jurídicos y éticos
2018
El desarrollo de las FIV, y en especial de la gestación por sustitución, los intereses y dignidad del menor y de la madre gestante se ven gravemente afectados y ponen de relieve las dificultades y desafíos a los que se enfrenta hoy el Derecho
El campo en la ciudad : representaciones y experiencias de los "fematers" en sus recorridos por Valencia (1878-1960)
2021
Este artículo analiza, por un lado, cómo eran percibidas las relaciones entre l'Horta y la ciudad de Valencia por las autoridades municipales y la prensa a través de sus representaciones de los fematers (agricultores encargados de la recogida de desperdicios urbanos); y por otro, cómo la última generación de este oficio ha dado sentido a sus recorridos pasados entre el campo y la ciudad. De acuerdo a las fuentes interpretadas (documentación interna consistorial, literatura, prensa y entrevistas orales) son contrastados tres contextos distintos. En primer lugar, el de sus conflictos sociales con el incipiente gobierno blasquista a principios del siglo XX; en segundo lugar, una etapa de males…
A single-point strategy based on IEEE 1459-2000 for the Detection of Dominant Harmonic Sources in Power Systems
2008
This paper deals with a novel single-point strategy for the detection of harmonic sources in power systems. It is an enhancement of a previous strategy, developed by authors, which is based on the IEEE Std. 1459-2000 approach. In the paper, the effectiveness of the strategy is investigated, by means of simulation tests, which were carried out on a IEEE standard three-phase test power system. The analysis is carried out by considering also the presence of the measurement transducers.

Hepatic metabolism of diclofenac: role of human CYP in the minor oxidative pathways.
1999
The aim of this study was to re-examine the human hepatic metabolism of diclofenac, with special focus on the generation of minor hydroxylated metabolites implicated in the idiosyncratic hepatotoxicity of the drug. Different experimental approaches were used: human hepatocytes, human microsomes, and engineered cells expressing single human CYP (cytochromes P450). Human hepatocytes formed 3'-hydroxy-, 4'-hydroxy-, 5-hydroxy- 4',5-dihydroxy-, and N,5-dihydroxydiclofenac, as well as several lactams. Formation of 4'- and 5-hydroxydiclofenac by human liver microsomes followed a Michaelis-Menten kinetics (Km 9 +/- 1 microM; Vmax 432 +/- 15 pmol/min/mg and Km 43 +/- 5 microM; and Vmax 15.4 +/- 0.6…
The relationship between out-of-school sport participation and positive youth development
2012
Carreres-Ponsoda F, Escarti A, Cortell-Tormo JM, Fuster-Lloret V, Andreu-Cabrera E. The relationship between out-of-school sport participation and positive youth development. J. Hum. Sport Exerc. Vol. 7, No. 3, pp. 671-683, 2012. Despite growing evidence that participation in out-of-school activities and especially physical activity and sport programs facilitates positive development, little developmental research has been conducted on out-of-school sports programs compared with no participation in these activities or participation in other activities. Our study examined the participation of youth in out of school sport activities compared with participation in other out-of-school activitie…
Extension of the Applicability of Jäntti's Method to the Fast Calculation of Desorption Data
2000
The time for sorption measurements may be reduced substantially by measuring several values at short time intervals at the beginning of a kinetic curve and extrapolating them to the equilibrium value. The method used by Jäntti for simple adsorption processes has been extended to complicated processes described by a second-order differential equation. A simulated example is provided.
