Investigation Of Bone Marrow Stem Cells In The Bone Marrow Niche In An In Vitro System

P. Lezuo, M. Stoddart, and M. Alini
AO Research Institute, Davos, Grison, Switzerland

We aim to develop an in vitro culture system to mimic the human bone marrow stem cell niche in an artificial perfusion bioreactor environment to culture human adult stem cells. State of the art human bone marrow stem cell research shows that even smallest changes in the physical, thermo dynamical or biochemical environment induce a differentiation of human bone marrow stem cells into other cell ...

Matching 4D Porous Media Fluid Flow GeoPET Data With COMSOL Multiphysics Simulation Results

J. Lippmann-Pipke, J. Kulenkampff, G. Marion, and M. Richter
Helmholtz-Zentrum Dresden
Rossendorf, Institut of Radiochemistry
Research Site Leipzig
Reactive Transport Division
Leipzig, Germany

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

COMSOL Multiphysics Modelling for Measurement Device of Electrical Resistivity in Laboratory Test Cell

C. Rémi, M. Bergeron, and S. Moreau
Antony, France

Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many physical parameters and no single relationship with volumetric water content was yet established for Municipal ...

Simulation of chaotic mixing dynamics in microdroplets

H. Zhou, L. Jiang, and S. Yao
The Hong Kong University of Science and Technology,
Hong Kong

Rapid mixing is of essential importance in many microfluidic applications such as chemical reactions, drug delivery, sequencing or synthesis of nucleic acids, protein crystallization, etc. However, it is difficult to mix fluids in microchannels since flows in these channels are generally laminar and molecular diffusion is usually insufficient to mix fluids. Using a combination of turns and ...

One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. In this work, we consider a simple model for air injection in light oil reservoir containing only one component in dry ...

Parametric Study of Electrolyte-Supported Planar Button Solid Oxide Fuel Cell

[1]Department of Mechanical, Materials and Aerospace Engineering, University of Central Florida, Orlando, FL, USA

Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical model of the SOFC and use of specifically designed software programs that allows the user to manipulate the ...

Numerical and Experimental Evaluation for Measurement of a Single Red Blood Cell Deformability Using a Microchannel and Electric Sensors

K. Tatsumi[1]
[1]Kyoto University, Kyoto City, Kyoto, Japan

An electric micro-resistance sensor that can continuously measure the deformability of a single red blood cell (RBC) in a microchannel and a numerical model that can simulate the resistance and capacitance of the cell membrane and cytoplasm are developed and improved. The resistance signal pattern between the electrodes is measured to evaluate the feasibility of the present sensor, using the ...

Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

C. Wang[1], Y. Song[1]
[1]Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL Multiphysics®, we applied the 1) Michaelis Menten equation; 2) Nernst potential equation; 3) Navier Strokes velocity, ...
