[1] Instituto Latino Americano de Pesquisa e Ensino Odontológico - ILAPEO, Curitiba, PR, Brasil
[2] Universidade Tecnológica Federal do Paraná – UTFPR, Curitiba, PR, Brasil

O presente estudo visou a avaliação, por meio do método dos elementos finitos, das tensões geradas em um arco ortodôntico chamado de Arco de Retração Dupla Chave, também conhecido como DKL. Para isso foram modeladas as geometrias do arco DKL, dos bráquets e das coroas dentais, no ... Read More

Large Scale Invasion Of New Species And Of Genetic Information

O. Richter, F. Suhling, and S. Moenickes
Technische Universität Braunschweig, Germany

The spatial dynamics of the invasion of new species and genetic dispersal is studied under the presumption of rising temperature by using a coherent approach of coupled partial differential equations of the reaction diffusion type. The nonlinear reaction terms model the population ... Read More

Bayesian Estimation of Tumors in Breasts Using Microwave Imaging

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

Although mammography is extremely important diagnostic technique, it suffers from some limitations such as false negative and positive results, using ionizing radiation and patient’s discomfort. Microwave imaging has been recently proposed as an additional medical imaging technique ... Read More

Two Dimensional Blood Shear Modeling in a Blood Cooling Catheter

R. Sikorski[1], B. Chapman[1], T. Merrill[1]
[1]Rowan University, Glassboro, NJ, USA

A CFD cardiac catheter model was developed to determine the potential for blood hemolysis during administration of local therapeutic hypothermia using a CoolGuide catheter. In vivo animal studies have shown that mild hypothermia may reduce reperfusion injury often associated with heart ... Read More

Photon Migration Through Multiple Layers of Biological Tissue

M.S. Yeoman[1], E. Sultan[2]
[1]Continuum Blue, Tredomen, Ystrad Mynach, United Kingdom
[2]College of Technological Studies, PAAET, Adailiyah, Kuwait

The modeling of light propagation through multiple layers of biological tissue are assessed & compared to the theoretical predictions by Perelman at al. [94 & 95] of the most-favorable-path (MFP). The MFP on which photons will be found can be obtained from the path of the net flux ... Read More

Modelling the Response of Microdialysis Probes in Glucose Concentration Measurement

J.M. Gozálvez-Zafrilla[1], A. Santafé-Moros[1], J.L. Díez-Ruano[2], J. Bondia[2]
[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain
[2]Instituto Universitario de Automática e Informática Industrial (AI2) - Universitat Politècnica de Valencia, Valencia, Spain

Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured ... Read More

Flow-induced Vibrations of the Uvula and its Implication on Snoring

J. Xi[1], Q. M. Mohamad[1], Y. E. Yuan[1], J. Rohlinger[1]
[1]Mechanical and Biomedical Engineering, Central Michigan University, Mount Pleasant, MI, USA

1. Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. 2. For a weak soft palate, complete flow occlusion can occur (sleep apnea). 3. Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing ... Read More

Modeling of an Oxygenation-Aided 3D Culture for Functional Beta-Cell Expansion

S. Jin[1], J. McReynolds[1], X. Li[2], J. Guan[2]
[1]Department of Biomedical Engineering, College of Engineering, University of Arkansas, Fayetteville, AR, USA
[2]Department of Materials Science and Engineering, The Ohio State University, Columbus, OH, USA

Currently, researchers are looking for ways to mass-produce biologically functional pancreatic beta cells in vitro because of the shortage of donor tissue needed for diabetes cell therapy. The beta cells will become hypoxic if their high oxygen demands are not met. We hypothesized that ... Read More

Simulating Thermotherapeutic Response Induced by Thermal Padding for Treating Acute Injuries

J. Kantor[1], Y. Feng[1], C. Acosta[1], E. Massingill[1]
[1]University of Texas at San Antonio, San Antonio, TX, USA

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of ... Read More

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 ... Read More
