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 ... 詳細を見る

Multiscale Electromagnetic Modeling of Contractions in the Pregnant Uterus new

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, ... 詳細を見る

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 ... 詳細を見る

Microvascular Dysfunction in PAD Patients new

K. Cluff[1], H. Mehraein[1], B. Jayakumar[2]
[1]Department of Bioengineering, Wichita State University, Wichita, KS, USA
[2]Department of Industrial & Manufacturing Engineering, Wichita State University, Wichita, KS, USA

Background: Peripheral arterial disease (PAD) is characterized by atherosclerotic blockages of the arteries supplying the lower extremities, which cause a progressive accumulation of ischemic injury to the skeletal muscles of the lower limbs. Despite revascularization treatment ... 詳細を見る

Design of Multiple Ground System for Maternal Defibrillation new

A. Jeremic[1], E. Khoshrowshahli[2]
[1]Electrical & Computer Engineering, McMaster University, Hamilton, ON, Canada
[2]Biomedical Engineering, McMaster University, Hamilton, ON, Canada

Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal ... 詳細を見る

Conductivity Estimation of Breast Cancer Using COMSOL® Modeling of Microwave Scattering and Frechet Mean Estimate of Covariance new

A. Jeremic[1], E. Khoshrowshahli[2]
[1]Electrical & Computer Engineering, McMaster University, Hamilton, ON, Canada
[2]Biomedical Engineering, McMaster University, Hamilton, ON, Canada

Breast cancer detection is one of the most important problems in health care and it is second most frequent cancer according to WHO. It is recommended that women over fifty or even younger in some cases do a screening test every two years. Besides clinical breast examination, there are ... 詳細を見る

Modeling of Hydrogel-Based Controlled Drug Delivery System for Breast Cancer Treatment new

K. Cluff[1], L. Saeednia[2], H. Mehraein [1], R. Asmatulu[2]
[1]Department of Bioengineering, Wichita State University, Wichita, KS, USA
[2]Department of Mechanical Engineering, Wichita State University, Wichita, KS, USA

Polymeric hydrogel is a promising class of drug delivery systems with the controlled release behavior in the body. In-situ forming hydrogels can be injected into the body as a fluid which forms a gel within the body tissue and improve the efficacy of the drugs. Various polymers have been ... 詳細を見る

Simulation and Experimental Analysis of Drug Release Rates from Magnetic Nanocomposite Spheres new
