Electrophoretic Focusing and Navigation for Intranasal Target Drug Delivery

X. Si[1]
[1]Calvin College, Grand Rapids, MI, USA

Direct nose-to-brain drug delivery circumvents the blood-brain-barrier and has multiple advantages over intravenous delivery. However, its application is limited by the extremely low delivery efficiency to the olfactory region. This study evaluated the feasibility of targeted drug ... En savoir plus

Simulating Experimental Conditions of the HIIPER Space Propulsion Device

A. Krishnamurthy[1], G. Chen[1], B. Ulmen[1], D. Ahern[1], G. Miley[1]
[1]University of Illinois at Urbana - Champaign, Urbana, IL, USA

The Helicon-Injected Inertial Plasma Electrostatic Rocket (HIIPER) is a two-stage electric propulsion system comprising of a helicon plasma source and an inertial electrostatic confinement (IEC) device for plasma production and acceleration, respectively. Several diagnostics such as a ... En savoir plus

Finite Element Analysis of Defibrillation Current Density in Pregnant Women

A. Jeremic[1], E. Khosrowshahli[1]
[1]McMaster University, Hamilton, ON, Canada

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a ... En savoir plus

Design Optimization of Printed Circuit Board Embedded Inductors through Genetic Algorithms with Verification by COMSOL Multiphysics®

[1]Technical University of Denmark, Lyngby, Denmark

This paper describes the implementation of a complete design tool for design, analysis, optimization and production of PCB embedded inductors. The paper shows how LiveLink™ for MATLAB® and COMSOL Multiphysics® make it possible to combine the scripting and calculation power of MATLAB ... En savoir plus

Finite Element Modeling of a Pulsed Eddy Current Probe for Steam Generator Tube Inspection

S. G. Mokros[1, 2], V. K. Babbar[1], T. W. Krause[1], J. Morelli[2]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada
[2]Department of Physics, Engineering Physics and Astronomy, Queen's University, Kingston, ON, Canada

Steam generator (SG) tubes in CANDU® nuclear reactors can lose efficiency in the presence of corrosion and its by-products. Condition monitoring of support structures could help direct maintenance activities and thereby increase SG tube lifetime. Pulsed eddy current (PEC) has been ... En savoir plus

Chemical Reaction Under Highly Precise Microwave Irradiation

S. Fujii[1], Y. Wada[2]
[1]Chiba University, Chiba, Japan
[2]Tokyo Institute of Technology, Tokyo, Japan

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... En savoir plus

Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... En savoir plus
