Radiofrequency (RF) technology offers unique advantages for noninvasive selective heating of relatively large volumes of tissue. In this work, we present a mathematical model for selective non-invasive, non-ablative RF heating of cutaneous and subcutaneous tissue (with detailed fiber ... Mehr lesen
• Bionanotechnology is a stream of modern science that deals with the study of biotechnology & nanotechnology applications. • Drug delivery applications as a key area of research attains more critical approaches where the role of nanoparticles are inevitable. • Biocompatible, non ... Mehr lesen
Articular cartilage is an avascular connective soft tissue in the diarthrodial joints and functions in a highly demanding mechanical environment. The degeneration or wear of the cartilage is a huge problem that effects millions of people every year. The long term objective of the ... Mehr lesen
The main reason for stent implantation is to provide mechanical support to the arterial wall. So it is important to consider the different mechanical properties of different stent materials while studying the stent implant’s efficacy. The present study gives a comparative overview of ... Mehr lesen
This work deals with the computer simulation of the blood flow, the arterial wall deformation and their 3D bidirectional interaction, including initial stresses and root displacements. The flow is laminar and steady with flexible walls modeled with a hyperelastic Demiray material model. ... Mehr lesen
Pranay Goel received his B. Tech. in Engineering Physics from IIT Bombay, and MS and PhD in Physics from the University of Pittsburgh in 2003. He went on to two postodoctoral positions, the first at the Mathematical Biosciences Institute, The Ohio State University, and another at the ... Mehr lesen
The aim of this study is to use tracking of flow artifacts in Magnetic Resonance Imaging of fluids to validate CFD. Phase Contrast MRI will also be used for comparison. The correlation between flow of the fluid and movement of the artifacts is investigated using an aorta flow phantom, ... Mehr lesen
For the development of bioreactor systems, it is reasonable to develop working simulations, to avoid a lot \"trial-and-error\" experiments. Our research goal is the creation of functioning bone grafts for transplantation. Therefore stem cells get homogenously seeded into porous ceramic ... Mehr lesen
In this paper we introduce a elastic and hyperelastic model to describe the pressure dependent material stress in joint cartilage. We used the pressure dependent E-modulus E = f(s) to calculate the material stress. E = f(s) is a degree 4 polynomial . The indentor was pressed 0.4 mm into ... Mehr lesen
In this paper we introduce a elastic and hyperelastic model to describe the biomechanics of joint cartilage. As biomechanical property we calculated the pressure dependent E-modulus E = f(s) to describe the dependence of the biomechanical properties on pressure. The calculation based on ... Mehr lesen
