[1]King Saud University, Riyadh, Saudi Arabia
[2]Washington State University, Pullman, WA, USA
[3]Northwest A&F University, Yangling, Shaanxi, China

Non-uniform heating is one of the most important challenges during the development of radio frequency (RF) heat treatments for pest control. A computer simulation model using finite element–based COMSOL Multiphysics® software was developed to investigate the heating uniformity of raisins ... Mehr lesen

Full System Modeling and Validation of the Carbon Dioxide Removal Assembly

R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... Mehr lesen

Stochastic Diffusion of Calcium Ions Through a Nanopore in the Cell Membrane Created by Electroporation

O. Henao[1], V. Gómez[1], I. De La Pava[1], J. Sánchez [1]
[1]Grupo Fisiología Celular y Aplicada, Universidad Tecnológica de Pereira, Pereira, Risaralda, Colombia

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the ... Mehr lesen

Simulation of Normal and Cancerous T-cell Membrane Electroporation

O. Henao[1], V. Gómez[1], I. De la Pava[1], J. Sánchez[1]
[1]Grupo Fisiología Celular y Aplicada, Universidad Tecnológica de Pereira, Pereira, Risaralda, Colombia

Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field [1][2]. The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs ... Mehr lesen
