Multiscale Model of Human Pathogen Growth on Fresh Produce

A. Warning[1], A. K. Datta[1]
[1]Department of Biological & Environmental Engineering, Cornell University, Ithaca, NY, USA

Predictive food microbiology currently first requires experimental data for growth on fresh produce and then fitting an empirical or semi-empirical model to the data, making extrapolation to other conditions (temperature, type of produce) difficult. Herein, we develop a mechanistic ... En savoir plus

Thermal Modeling in a Historical Building - Improving Thermal Comfort Through the Siting of a Passive Mass of Phase Change Material

D. Groulx[1], F. Herbinger[1], L. Desgrosseilliers[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

A model of an office room was created in the COMSOL Multiphysics® software to simulate heat transfer and study the impact of siting a mass of phase change material (PCM) in a room to increase thermal comfort. This study determined that incorporating the selected PCM, butyl stearate, in ... En savoir plus

Estimation of Hydraulic Conductivity for a Heterogeneous Unsaturated Soil Using Electrical Resistivity and Level-Set Methods

T. K. Chou[1], M. Chouteau[1], J. S. Dubé[2]
[1]École Polytechnique de Montréal, Montréal, QC, Canada
[2]École de Technologie Supérieure, Montréal, QC, Canada

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... En savoir plus

Design and Simulation of High-Throughput Microfluidic Droplet Dispenser for Lab-on-a-Chip Applications

[1]Department of Biomedical Engineering, University of Bridgeport, Bridgeport, CT, USA
[2]Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[3]Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

Digital Microfluidic Biochip (DMFB) has been widely used in Lab-on-a-Chip (LoC) for disease diagnosis and treatment applications. To quickly convert traditional analog fluidic sample into digital droplets for DMFB processing, a high-throughput microfluidic droplet dispenser device is ... En savoir plus

Improving Heating Uniformity of Dried Fruit in RF Treatments for Pest Control: Model Development and Validation

B. Alfaifi[1], J. Tang[2], Y. Jiao[2], S. Wang[3], B. Rasco[2], S. Jiao[2], S. Sablani[2]
[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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus
