Aplicaciones de campos eléctricos moderados para mejorar los fenómenos de transporte de calor en el procesado de alimentos

Colomer Pérez, Borja Amadeo (Universitat Politècnica de València, 2021-01-04)

[ES] Al aplicar una corriente eléctrica a través de un alimento, se genera calor en el interior, lo que provoca un calentamiento uniforme, un daño estructural mínimo y, por lo tanto, una mejor conservación de sus nutrientes. ...
Application of electric fields to clean ultrafiltration membranes fouled with whey model solutions

Corbatón Báguena, María José; Alvarez Blanco, Silvia; Vincent Vela, Maria Cinta; Ortega Navarro, Emma María; Pérez-Herranz, Valentín (Elsevier, 2016)

In this work, the effectiveness of electric fields to clean two ZrO2 TiO2 ultrafiltration (UF) membranes fouled with three types of whey model solutions was investigated. Membranes tested had different molecular weight ...
Capacitively Coupled Electrical Stimulation of Rat Chondroepiphysis Explants: A Histomorphometric Analysis

Vaca-González, J. J.; Escobar, J.F.; Guevara, J.M.; Hata, Y. A.; Gallego-Ferrer, Gloria; Garzón-Alvarado, D. A. (Elsevier, 2019-04)

[EN] The growth plate is a cartilaginous layer present from the gestation period until the end of puberty where it ossifies joining diaphysis and epiphysis. During this period several endocrine, autocrine, and paracrine ...
Design and implementation of a low cost isotropic electric field sensor for SAR measurements

Quispe, Marco; Samaniego, Javier; Olivares, Jorge; Adriano, Rolando; Pérez, B.; Inca, Saúl (Institute of Electrical and Electronics Engineers, 2024-11)

[EN] Specific Absorption Rate (SAR) measurement systems are used to evaluate exposure to fields radiated by wireless devices placed close to people's bodies. One of the fundamental elements of these systems is an isotropic ...
Effect of electrical stimulation on chondrogenic differentiation of mesenchymal stem cells cultured in hyaluronic acid - Gelatin injectable hydrogels

Vaca-González, Juan Jairo; Clara-Trujillo, Sandra; Guillot-Ferriols, María Teresa; Ródenas Rochina, Joaquín; Sanchis Sánchez, María Jesús; Gómez Ribelles, José Luís; Garzón-Alvarado, Diego Alexander; Gallego-Ferrer, Gloria (Elsevier, 2020-08)

[EN] Electrical stimulation (ES) has provided enhanced chondrogenesis of mesenchymal stem cells (MSCs) cultured in micro-mass without the addition of exogenous growth factors. In this study, we demonstrate for the first ...
Explicit finite-difference time-domain scheme for the simulation of 1-3 piezoelectric effect in axisymmetrical configurations

Ferri García, Marcelino; Camarena Femenia, Francisco; Redondo, Javier; Picó Vila, Rubén; Avis, Mark R. (Elsevier, 2012-09)

[EN] Numerical simulations are useful in the processes of design, development and optimization of transducers for non-destructive testing. In this work, a three-dimensional velocity-stress finite-difference model is presented ...
Low order modes in microcavities based on silicon colloids

Xifre Perez, Elisabet; Fenollosa Esteve, Roberto; Meseguer Rico, Francisco Javier (Optical Society of America, 2011-02-14)

[EN] Silicon colloids based microcavities, with sphere size between 1 and 3 micrometers, have been synthesized and optically characterized. Due to both the small cavity volume and the high refractive index of silicon we ...
Multipactor theory for multicarrier signals

Anza Hormigo, Sergio; Mattes, Michael; Vicente Quiles, Carlos Pascual; Gil Raga, Jordi; Raboso García-Baquero, David; Boria Esbert, Vicente Enrique; Gimeno Martinez, Benito (American Institute of Physics (AIP), 2011-03)

This work presents a new theory of multipactor under multicarrier signals for parallel-plate geometries, assuming a homogeneous electric field and one-dimensional electron motion. It is the generalization of the nonstationary ...
Sector Unit-Cell Methodology for the Design of Sub-6 GHz 5G MIMO Antennas

Molins-Benlliure, Jaime; Cabedo Fabres, Marta; Antonino Daviu, Eva; Ferrando Bataller, Miguel (Institute of Electrical and Electronics Engineers, 2022)

[EN] A novel methodology based on the sectorization of multiple-port cavities with azimuthal symmetry into sector unit cells is presented to design 5G multiple-input multiple-output (MIMO) sub-6 GHz antennas. The methodology ...
