Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A computational model of a SWCNT device was developed using COMSOL Multiphysics to investigate the complete electrical ...

Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field . The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs into the cell in a cancer treatment known as electrochemotherapy . In some cases the direct experimental ...

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 be performed to predict the temperature distributions. Changes in storage temperature may occur due to several ...

Introduction: Singlet oxygen (¹O₂) has a critical role in the cell-killing mechanism of photodynamic therapy (PDT). Therefore, in this study, the distance-dependent reacted ¹O₂ is numerically calculated using finite-element method (FEM). Herein, we use a model [Ref. 1] that has been previously developed to incorporate the diffusion equation for the light transport in tissue and the macroscopic ...

In order to achieve an optimized design of the Multi-Lumen Thoracic Catheter (MLTC), fluid dynamics analyses were conducted utilizing COMSOL Multiphysics® software with LiveLink™ for Solidworks®. Lumen placement, diameters, and termination points were adjusted to ensure maximum drainage efficacy. It was determined through this study that even with the additional flow through the access lumen, ...

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices provide freedom from the social and practical difficulties of using conventional hearing aids. The paper presents ...

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By solving the model using COMSOL, it was possible to predict the concentration of bacteria at points within the ...

Singlet oxygen (1O2) is the major cytotoxic agent during photodynamic therapy (PDT). A previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic kinetic equations for the generation of the singlet oxygen, can be used to numerically calculate the distance-dependent reacted 1O2 using finite-element method (FEM). The formula of reacted ...

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 considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

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 intervention some PAD patients require follow up secondary treatment due to a continued decline in limb function, ...
