The magnetic body forces that act on mono-dispersed magnetic nanoparticles (MNPs) tagged biomolecules in a microfluidic system can be efficiently used in various applications that involve separation and detection including DNA and protein analysis, bio-defense, drug delivery, and pharmaceutical development. In this work, we report an FEM model to demonstrate a novel method of tagging ...

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 ...

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. ...

Porous membranes with pore sizes in the micrometer scale are required in many micro systems dedicated to biological and chemical applications. If their thickness is in the same dimension like the pore diameter they are called microsieves. On the one hand, a thin membrane guarantees a small flow resistance but on the other hand the mechanical strength is reduced. We developed a process which ...

The aim of this Project is to obtain a temporary and spatial evolution model of the temperature into a meeting room with the aim to develop an efficient energy mechanism which can improve the air conditioner control system. The project has considered two extremes cases: on the one hand a typical summer day and on the other hand a winter day. From annual data of the Institute weather station a ...

Singlet oxygen (1O2) is the major cytotoxic agent in photodynamic therapy (PDT). The reaction between 1O2 and tumor cells defines the treatment efficacy. Based on 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, the distance-dependent reacted 1O2 is numerically ...

In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well-performed invisible cloak, based on an empirical revised version of the reduced cloak. The cloak is numerically ...

Determination of tissue optical properties distributions is very important for determining light fluence distribution during photodynamic therapy (PDT). In this study, an interstitial diffuse optical tomography (iDOT) system was used to characterize the spatial distribution of optical properties for a series of mathematical phantoms as well as verification measurements in a prostate phantom. ...

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have operation with gas pressure as low as possible (0.3 Pa). A multiphysics model of some major processes is here ...
