Numerical Simulation of Magnetic Drug Targeting with Flow – Structural Interaction in an Arterial Branching Region of Interest
We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image ... En savoir plus
Cavity Sprayer Flow Optimization for Medical Devices Industry
Globally in Otolaryngology industry, Sinusitis is one of the most common diseases related to the nose. Sinusitis is caused when the cilia fail to move the mucus. As a result sinus tissue gets infected that leads to blockage of the sinuses. All the sinusitis can not be cured through drugs ... En savoir plus
Influence of pH and Carbonate Buffering on the Performance of a Lactate Microbial Fuel Cell
Microbia Fuel Cells (MFC’s) are complex environments where electrochemical, physical and biological aspects must be considered together. In this work we present a 1D model partially describing a Shewanella oneidensis MFC that degrade sodium lactate [lactate -> Acetate + CO2 + 2H+ + 2e-]. ... En savoir plus
Search for a Suitable Numerical Model for Electrical Stimulation: from the Electric Double Layer to Electrokinetics, Confrontation with Impedance Measurements
Electrical Stimulation is widely used today for Deep Brain Stimulation treatments and retinal prostheses. The Electrical Double Layer formed at the interface between the electrode surface and the extracellular medium is considered thru the linear Helmholtz model and the nonlinear more ... En savoir plus
From CT Scan to Plantar Pressure Map Distribution of a 3D Anatomic Human Foot
Understanding the stress-strain behavior of human foot tissues and pressure map distributions at the plantar interface is of interest into biomechanical investigations. In particular, monitoring plantar pressure maps is crucial to establishing the perceived human comfort of shoe insoles. ... En savoir plus
Modeling of Retinal Electrical Stimulation Using a Micro Electrode Array Coupled with the Gouy-Chapman Electrical Double Layer Model to Investigate Stimulation Efficiency
The electrical stimulation for retinal implant has known significant improvements in the last decades with many implantations and experimentations. The ability to create better controlled and adapted signals to increase the efficiency in stimulation is a major objective. The aim of this ... En savoir plus
Some Clinical and Computational Studies On Haemodynamics In Stenosed Artery
Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always ... En savoir plus
Detection of E.coli Cell using Capacitance Modulation
Testing and verification is very important to increase reliability of a system. In water analysis its purity is verified using different test methods. Biosensors are very useful to detect the microorganisms present in water. This paper presents a method to detect E.coli bacteria in water ... En savoir plus
The Effect of Cartilaginous Rings on Deposition by Convection, Brownian Diffusion and Electrostatics
This paper presents a numerical study of the deposition of spherical charged nanoparticles caused by convection and Brownian diffusion in a pipe with a cartilaginous ring structure. The model is supposed to describe deposition of charged particles in the upper generations of the ... En savoir plus
Modeling Heat and Mass Transfer in Bread During Baking
In this paper, we present a first model carried out with COMSOL Multiphysics to model bread baking, considering heat and mass transfer coupled with the phenomenon of swelling. This model predicts the pressures, temperatures and water contents evolutions in the dough for different energy ... En savoir plus
