Praxis solidaria: una propuesta conceptual a partir de la obra de Paulo Freire
Published 2023-07-01“…El presente trabajo tiene un doble propósito, a saber: a) realizar un análisis sobre las categorías de falsa generosidad y de solidaridad en la obra de Paulo Freire, para dar cuenta de la forma en que se revisten los elementos constitutivos de los procesos de formación para imprimirles una direccionalidad ético-política particular; y b) esbozar una propuesta sobre la noción de praxis solidaria, a partir de repensar el legado freireano, con el fin de situarla como una categoría que puede ser habitada de múltiples maneras, teniendo como base el ethos que se configura en cada experiencia político-pedagógica. …”

Schmidt modes carrying orbital angular momentum generated by cascaded systems pumped with Laguerre–Gaussian beams
Published 2025-01-01“…In this work, we present a theoretical approach to the generation of correlated Schmidt modes carrying OAM via parametric down-conversion (PDC) in cascaded nonlinear systems (nonlinear interferometers) pumped by Laguerre–Gaussian beams. We demonstrate how the number of generated modes and their population can be controlled by varying the pump parameters, the gain of the PDC process, and the distance between the crystals. …”

A Mathematical Model for the Flow of a Casson Fluid due to Metachronal Beating of Cilia in a Tube
Published 2015-01-01“…A mathematical model is developed to study the transport mechanism of a Casson fluid flow inspired by the metachronal coordination between the beating cilia in a cylindrical tube. A two-dimensional system of nonlinear equations governing the flow problem is formulated by using axisymmetric cylindrical coordinates and then simplified by employing the long wavelength and low Reynolds number assumptions. …”
