Small nuclear ribonucleoprotein particles (snRNPs) are essential supramolecular complexes involved in pre-mRNA splicing, the process of post-transcriptional RNA modifications. The particles undergo complex assembly steps inside the cell nucleus in a highly dynamic compartment called the Cajal body. We have previously shown that the free diffusion model does not fully describe the snRNP motion ...

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...

Photodynamic therapy(PDT) is a new cancer treatment modality using the photochemical reaction of a photosensitizing drug, light, and oxygen. The objective of this project is to determine the photochemical parameters necessary for singlet oxygen modeling during PDT using parameters obtained from a microscopic model. FEM calculation in COMSOL Multiphysics was used to determine the model ...

Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like electroactive polymers (EAPs) or metal oxides. This work investigates the stresses and heat flux of the electrode ...

This paper describes using thermal-structural interaction to model the shrinkage behavior in cement paste under drying. An inverse method of combining the finite element analysis and the least-squares method is implemented to fit experimentally determined shrinkage in order to obtain material properties from the complex geometry used in the tests. The finite element model is created using COMSOL ...

Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a defined number of holes on its top and bottom lines, maintaining semi-captive air between itself and the gun. The ...

Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating particle system including damping in order to damp out the time derivatives and attain a stationary solution ...

In COMSOL Multiphysics it is possible to implement and simulate several independent models in parallel. This can be meaningful when the different models are coupled to each other by some kind of interaction. If a part of the geometries is identical in all models, this part can be reduced in that it is implemented in only one of the geometries. In the other geometries only its solution towards its ...
