Llanes Estrada, Felipe José ; Torres Rincón, Juan Miguel ; Cabrera Urban, Daniel | Academic Press Inc Elsevier Science | 2011-10We compute the charm drag and diffusion coefficients in a hot pion gas, such as is formed in a heavy ion collision after the system cools sufficiently to transit into the hadron phase. We fully exploit heavy quark effective theory (with both D a[...]texto impreso
Méndez González, Diego ; Gómez Calderón, Óscar ; Melle Hernández, Sonia ; González Izquierdo, Jesús ; Bañares Morcillo, Luis ; López Díaz, David ; Velazquez Salicio, M. Mercedes ; Lopez Cabarcos, Enrique ; Rubio Retama, Jorge ; Laurenti, Marco | Academic Press Inc Elsevier Science | 2020-04-20Upconversion nanoparticles (UCNP) are increasingly used due to their advantages over conventional fluorophores, and their use as resonance energy transfer (RET) donors has permitted their application as biosensors when they are combined with app[...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 2002-03-01The current-voltage curves for a cation-exchange membrane separating two equal methanol-water electrolyte solutions were determined under different experimental conditions. From these curves, the values of the limiting current density, I-L, were[...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 1998-09-15The curves (V, I) of different ion-exchange membranes have been determined under different experimental conditions. Taking into account the classical theory of concentration polarization, a method has been developed to adjust the (V, I) data, up[...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 2001-08-01The effect of an ac sinusoidal perturbation of known amplitude and frequency superimposed on the usual dc applied electric voltage difference on the electroosmotic flow through a typical cation-exchange membrane has been studied using different [...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 1997-11-01The water electroosmotic flux, J(v), through a cation exchange membrane has been measured as a function of the temperature, T, with various values of the electrolyte concentration and for different current densities. From these measurements the [...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos ; Mengual Cabezón, Juan Ignacio | Academic Press Inc Elsevier Science | 1994-12Electro-osmotic fluxes of water through two cation-exchange membranes have been measured under different experimental conditions. The influence of unstirred solution layers adjoining the membrane surfaces on the obtained values has been studied [...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 2000-10-15Electroosmosis experiments through a cation-exchange membrane have been performed using NaCl solutions in different experimental situations. The influence of an alternating (ac) sinusoidal perturbation, of known angular frequency and small ampli[...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 1999-04-01The electroosmotic flux through a cation-exchange membrane has been obtained in different situations. From these measurements, the apparent electroosmotic permeability, W, of a cation-exchange membrane has been determined as a function of the te[...]texto impreso
Barragán García, Vicenta María ; García Villaluenga, Juan Pedro ; Godino Gómez, María Paz ; Izquierdo Gil, María Amparo ; Ruiz Bauzá, Carlos ; Seoane Rodríguez, Benjamín | Academic Press Inc Elsevier Science | 2009-05-15Solvent uptake, hydraulic and electroosmotic permeabilities, true cation transport number, effective fixed charge concentration, and limiting current values have been determined in aqueous LiCl solutions for three commercial cation-exchange memb[...]texto impreso
Álvarez, Gabriel ; Martínez Alonso, Luis ; Medina Reus, Elena | Academic Press Inc Elsevier Science | 2015-10In this paper we apply results on the asymptotic zero distribution of the Laguerre polynomials to discuss generalizations of the standard large n limit in the non-hermitian Penner matrix model. In these generalizations g_(n)n ? t, but the produ[...]texto impreso
Azcoitia Elías, Iñigo ; Arévalo, María Ángeles ; Santos Galindo, María ; Acaz Fonseca, Estefanía ; García Segura, Luis Miguel | Academic Press Inc Elsevier Science | 2013-02Astrocytes and microglia respond to central nervous system (CNS) injury with changes in morphology, proliferation, migration and expression of inflammatory regulators. This phenomenon is known as reactive gliosis. Activation of astrocytes and mi[...]texto impreso
Branquinho, Amilcar ; Foulquié Moreno, Ana ; Mañas Baena, Manuel | Academic Press Inc Elsevier Science | 2021-02-15In this paper we use the Riemann-Hilbert problem, with jumps supported on appropriate curves in the complex plane, for matrix biorthogonal polynomials and apply it to find Sylvester systems of differential equations for the orthogonal polynomial[...]texto impreso
Finkel Morgenstern, Federico ; González López, Artemio | Academic Press Inc Elsevier Science | 2014-12The aim of this paper is studying from an alternative point of view the integrability of the spin chain with long-range elliptic interactions introduced by Inozemtsev. Our analysis relies on some well-established conjectures characterizing the c[...]texto impreso
Barragán García, Vicenta María ; Rueda Sánchez, Cristóbal ; Ruiz Bauzá, Carlos | Academic Press Inc Elsevier Science | 1995-06-15The ionic permeselectivity of a cellulose acetate membrane prepared in our laboratory has been studied from membrane potential and electroosmotic flux measurements. The obtained results show that, at low values of the external salt concentration[...]
