Transport and Concentration of Charged Molecules in a Lipid Membrane

S. D. Evans[1], J. S. Roth[1], M. R. Cheetham[1]
[1]University of Leeds, Leeds, UK

Brownian ratchets and electric fields are used for the transport of membrane components. Transport is achieved through the combination of a pattern with free diffusion. We show a good agreement between simulation and experiment, therefore allowing for further optimisation of the ratchets ... En savoir plus

Calibration of a Bio-Kinetic Model to Simulate Microalgae Growth

A. Solimeno[1], J. Garcia[2]
[1]Department of Hydraulic, Maritime and Environmental Engineering, Universitat Politècnica de Catalunya, Barcelona, Spain
[2]Universitat Politecnica de Catalunya, Barcelona, Spain

The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes ... En savoir plus

Efficient, Selective Piezoeletric Wave Transduction Using Interdigitated Electrodes

H. T. D. Grigg[1], T. H. Hanley[1], B. J. Gallacher[1]
[1]Newcastle University, Newcastle, Tyne and Wear, UK

This work enunciates the principles of SAW design from a physical perspective, examining the standard engineering modelling assumptions in some detail. An integral form analytical expression based on 2D elastic isotropic theory is validated against a COMSOL Multiphysics® simulation, ... En savoir plus

Comparative Study on 3D Modeling of Breast Cancer Using NIR-FDOT

S. Peter[1]
[1]Christ University, Bengaluru, Karnataka, India

Fluorescence Diffuse Optical Tomography (FDOT) uses Near Infra-Red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such ... En savoir plus

3D-FEA of the Relationship between the Occiput and Sphenoid in the Osteopathic Paradigm

Y. Chiesa[1]
[1]Istituto Superiore di Osteopatia, Milan, Italy

The concept of cranial Primary Respiratory Mechanism (MRP) is used by osteopathic practitioners to explain the perceptual characteristics arising from the clinical palpation approach of the human skull. The theoretical apparatus and the same MRP existence is always element of ... En savoir plus

Modelling of the Oxygen Consumption of Cells in the Cell Culturing Platform

A. Niazi[1]
[1]School of Mechanical Engineering, University of Birmingham, Birmingham, United Kingdom

A device for monitoring the oxygen consumption of cells has been developed, which consists of two parts; a cell culturing platform (CCP) and an oxygen sensing chip. The CCP possesses inlet and outlet pipes to direct the fluid under the test to the cell culturing chamber through the inlet ... En savoir plus

Design of a Cylindrical Photobioreactor with Central Orifice for the Production of Microalgae

N. N. V. Ramirez[1], L. M. Raymundo[1], J. O. Trierweiler[1]
[1]Federal University of Rio Grande do Sul, Porto Alegre, RS, Brazil

It is desired to design a photobioreactor for the production of voluminous samples of microalgae for lipid quantification. The reactor should provide good growing conditions even with periodic withdrawal of samples. It also should be compact for better use of laboratory space. Therefore, ... En savoir plus

Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses

B. Liu[1]
[1]Department of Mathematics, Monmouth University, West Long Branch, NJ, USA

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the ... En savoir plus

Finite Element Modeling of Vasoreactivity Using COMSOL Multiphysics® Software

J. Parikh[1], A. Kapela[1], N. Tsoukias[1]
[1]Biomedical Engineering Department, Florida International University, Miami, FL, USA

Localized calcium events in the endothelial cells (EC) can modulate smooth muscle cell (SMC) calcium (Ca2+) and membrane potential dynamics through release of endothelium derived hyperpolarizing and relaxing factors. Ca2+ levels in the smooth muscle cell (SMC) determine its contractile ... En savoir plus

FEM Simulation of Magnetically Triggered Hydrogel Micro Particles as Advanced Drug Carriers

O. Yassine[1], M. Kavaldzhiev[1], J. Kosel[1], Q. Li[1], A. Alfadhel[1], A. Zaher[1]
[1]Electrical Engineering Division, CEMSE Group, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

Thermally responsive microgel Poly (N-isopropylacrylamide), particles are embedded with iron oxide nanobeads creating magneto-thermally responsive microparticles (MTMs). The magnetic losses in the nanobeads activate the PNIPAM by heating it up to its lower critical solution temperature ... En savoir plus
