[1]Cornell University, Ithaca, NY, USA

The objective of this study was to develop an easy to use interface in Excel® that connects to not only the solvers in COMSOL Multiphysics®, but also existing databases of food properties, foodborne pathogenic microorganisms kinetics, and chemical kinetics, creating a comprehensive ... Saiba Mais

Computational Modeling of the Electrohydrodynamics Influencing Trace Mercury Adsorption within Electric Utility Electrostatic Precipitators

H. Clack[1]
[1]University of Michigan, Ann Arbor, MI, USA

Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... Saiba Mais

[3] Department of Anesthesiology, New York Methodist Hospital, Brooklyn, NY, USA

Introduction: While general anesthetics control pain via consciousness regulation, local anesthetics (LAs) act by decreasing sensation in the area of administration by blocking nerve transmission to pain centers. Perioperative intra-articular administration of LAs is a commonly employed ... Saiba Mais

A Model to Simulate Laser Ablation in Tumor Using Dynamic Photothermal Coupling Interaction Model

Zhifang Li [1], Xiyang Zhang [1],
[1] College of Photonic and Electronic Engineering, Fujian Normal University, Fuzhou, China

Laser immunotherapy (LIT) was developed to treat late-stage, metastatic cancers through local laser irradiation and immunological stimulation. In ILIT, the photothermal effect induces immune responses by destroying and interrupting tumor cells through temperature elevation in target ... Saiba Mais

Evaluation of the Induced Excitation of the Peripheral Vestibular System Using Micro Scale Inductors

S. Mukesh [1], P. Bhatti [1],
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

According to the National Health and Nutrition Examination Survey data, 35 % of US adults aged 40 years and older have evidence of balance dysfunction based on the modified Romberg test. In this vestibular dysfunction, patients are not able to see stabilized images on their retina during ... Saiba Mais

Simulation of Deformed Solid Particles in Constrained Microfluidic Channel

M. Cartas-Ayala[1], R. Karnik[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Characterization of particles has numerous applications in science and diagnostics. Recently, particle passage through constrained microchannels has been proposed to characterize particles based on their passage velocity. Nevertheless, there is no clear understanding of how the physics ... Saiba Mais

Downscale Finite Element Modeling of Aortic Valve Leaflets for In-Situ Estimation of Cell Level Mechanics
