Organ-on-a-chip microdevices combine microfluidics, MEMS, and biotechnology techniques to mimic the multicellular architectures, tissue-tissue interfaces, physicochemical microenvironments, and vascular perfusion of the body. Such devices are being developed to provide better levels of tissue and organ functionality compared with conventional cell culture systems, and have great potential to ...

Drop test simulation is one of the important tool used for the impact behaviour study of electronic components. It identifies the flaws in design. The reliability and performance of electronic consoles after the drop is a major concern. Devices are expected to continue functioning after suffering a drop. The model is allowed to fall freely due to gravity load application. Drop test standard ...

A CFD cardiac catheter model was developed to determine the potential for blood hemolysis during administration of local therapeutic hypothermia using a CoolGuide catheter. In vivo animal studies have shown that mild hypothermia may reduce reperfusion injury often associated with heart attack. The CoolGuide Catheter System (CCS) delivers rapid local cooling through a cardiac catheter, reducing ...

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an ...

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 ...

We are developing approximations of electrically anisotropic materials for use in novel imaging methods. Our modeling work in COMSOL comprises comparisons of anisotropic and layered models in terms of electrical conductivities measured using different strategies. We tested solution stability in one anisotropic case by varying mesh anisotropy. In our case, good approximations to the true ...

Organogenesis is a tightly regulated process that has been studied experimentally for decades. Computational models can help to integrate available knowledge and to better understand the underlying regulatory logic. We are currently studying mechanistic models for the development of limbs, lungs, kidneys, and bone. We have tested a number of alternative methods to solve our spatio-temporal ...

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 work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include electro-osmotic flow, species transport, and electrostatics.

A general description of effects of toxic compounds in mammalian cells is facing several problems. Firstly, most toxic compounds are hydrophobic and partition phenomena strongly influence their behaviour. Secondly, cells display considerable heterogeneity regarding the presence, activity and distribution of enzymes participating in the metabolism of foreign compounds i.e. bioactivation ...
