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

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 ... Read More

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

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 ... Read More

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

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, ... Read More

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

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 ... Read More

Finite Element Modeling of Vasoreactivity Using COMSOL Multiphysics® Software new

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 ... Read More

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

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 ... Read More

Modeling and Simulation of Drug Release through Polymer Matrices new

V. Runkana[1], A. Pareek[1], P. Arora[2]
[1]Tata Consultancy Services, Pune, Maharashtra, India
[2]Indian Institute of Technology Delhi, New Delhi, Delhi, India

Limited drug efficacy, undesirable temporal changes in drug concentration and patient non-compliance due to frequent dosing schedule have given impetus to design of controlled drug release systems [1]. Biodegradable polymers due to their favorable and tunable properties and ... Read More

Multiphysics Modeling of a Grain Storage Chamber new

P. Guha[1], P. Sharma[1], V. Malhotra[1], S. Mishra[1]
[1]CSIR - Central Scientific Instruments Organisation, Chandigarh, India

Proper storage of grains depends on minimizing attacks of insects, fungi, mites, etc. Development of such pests can be controlled by controlling the temperature of the storage chamber. Hence, before designing grain storage chambers, mathematical modeling and numerical simulations should ... Read More

Multiscale Electromagnetic Modeling of Contractions in the Pregnant Uterus new

V. Tidwell[1], P. LaRosa[2], M. Zhang[1], H. Eswaran[3], A. Nehorai[1]
[1]Department of Electrical & Systems Engineering, Washington University in St. Louis, St. Louis, MO, USA
[2]Monsanto Company, Technology Pipeline Solutions, St. Louis, MO, USA
[3]OB/GYN Department, University of Arkansas for Medical Sciences, Little Rock, AR, USA

Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, ... Read More

Magnetostatic-Magnon Sensors for Microwave Microscopy of Biological Structures new

E. Hollander[1], E. O. Kamenetskii[1], R. Shavit[1]
[1]Microwave Magnetic Laboratory, Department of Electrical and Computer Engineering, Ben Gurion University of the Negev, Beer Sheva, Israel

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is ... Read More
