A numerical finite element model of one human brain is built in COMSOL in order to study a particular form of hydrocephalus, the so called Normal Pressure Hydrocephalus (NPH). The geometry of the ventricles and the skull is obtained by Magnetic Resonance Imaging (MRI) and imported in COMSOL Multiphysics. Form the mechanical point of view, the brain parenchyma is modeled as a porous medium fully ...

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, ...

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics-multiphase porous media model in COMSOL to determine the effect of combining different heating modes on heating ...

Testing and verification is very important to increase reliability of a system. In water analysis its purity is verified using different test methods. Biosensors are very useful to detect the microorganisms present in water. This paper presents a method to detect E.coli bacteria in water depending upon the capacitance modulation in the presence and absence of E.coli cell, which is simulated in ...

Giant vesicles (GVs) are artificial chemical systems largely used as cell models, since they are micrometer-sized closed compartments bounded by a semi-permeable membrane, which in turn is composed by self-assembling amphiphiles. By opportunely engineering the lipid membrane and by entrapping cascade-reaction enzymes inside GVs, it is possible to design micro-sized reactors where metabolic ...

During cryopreservation of human embryos, ice crystal formation in the embryos or in surrounding media may cause cryodamage to them and can be lethal. A strategy to avoid this is the vitrification procedure when the embryo and the surrounding medium undergo the transition to glassy state rather than a crystalline one during cooling. Similarly, recrystallization in the embryo or the medium must ...

Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always present the real picture due to non-uniformity of the stenosis thickness. The present work attempts to simulate the ...

Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological examination with MRI/CT scans which is costly and time consuming. Microwave Tomography (MWT) is proposed as a ...

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is driven by the motion of the arterial wall within a separate compartment outside the artery. A constant ...

Schistosoma mansoni parasites affect million people worldwide. The intensity of the infection can be evaluated by the number of eggs present in the stool of an infected individual. The application of the traditional methods has been regarded as impractical in developing areas and there is a continuous search for new techniques. In face of this scenario, a new method of diagnosis was explored in ...
