The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes mainly based on River Water Quality Model 1 (RWQM1) (Reichert et al., 2011). The main innovation of the model is ...

Understanding the stress-strain behavior of human foot tissues and pressure map distributions at the plantar interface is of interest into biomechanical investigations. In particular, monitoring plantar pressure maps is crucial to establishing the perceived human comfort of shoe insoles. A 3D anatomical detailed FE human foot model was created, starting from CT (Computer Tomography) scans of a ...

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal neurons and retinal ganglion cells (RGC) in order to restore vision. In this paper, the electrode-tissue ...

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be clarified. Acoustic environmental stimuli at different intensities are continuously interacting with our bodies, ...

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the process of ionic diffusion in a 2D nanopore model using the AC/DC Module and the Transport of Diluted Species ...

Acute respiratory distress syndrome (ARDS) is a severe lung disease caused by a variety of direct and indirect insults. The main treatment for ARDS is mechanical ventilation. The ventilation of fluid filled lungs involves the propagation of microbubbles over a layer of epithelial cells. We utilized COMSOL® with MATLAB® to develop a time dependent computational model of semi-infinite air ...

This paper proposes a novel data-mining framework to simulate the spread of epidemic diseases using persistent surveillance data. The framework is formulated by merging the persistent surveillance data about epidemics, geographic information and the dynamics of disease into a heat transfer model according to the theory of statistical mechanics . In the implementation of this framework, geographic ...

Cardiovascular disease has become a major healthcare problem. To tackle this along with bypass surgery, the use of the cardiovascular stent is considered promising and effective. In this study, we aim to find the effectiveness of stent deployments and their influence on haemodynamics post their deployment in human arteries. For the study we have reconstructed single units of two commercially ...

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 used as in-situ hydrogel formulations. These polymeric formulations can form gels at body temperature while ...
