A multi-scale approach to electrospray ion source modeling has been developed. The evolution of a single-emitter plume in pure ionic regime is simulated with combination electrohydrodynamic fluids and n-body particle modeling. Simulations are performed for the liquid, EMI-BF4, firing positive pure-ion mode. metastable nature clusters captured using an fragmentation model informed by molecular d...

materials used in the body, especially the materials used in various oral cavity regions should be stable and passive without any interactions with the body tissues or fluids. dental amalgam, c omposite resins and dental cements are the materials of choice with such properties. the first attempts to produce active materials, which could interact with the human body tissues and fluids were promp...

We present a technique for coupling simulated fluid phenomena that interact with real dynamic scenes captured as a binocular video sequence. We first process the binocular video sequence to obtain a complete 3D reconstruction of the scene, including velocity information. We use stereo for the visible parts of 3D geometry and surface completion to fill the missing regions. We then perform fluid ...

Two facts must be taken into consideration when quantifying fibronectin in biological samples: the sensitivity of the assay method and the appropriate handling of samples. A three-antibody, non-competitive ELISA was used in the present study. This procedure offers a simple, inexpensive and very sensitive technique for evaluating fibronectin: reproducible standard curves in the range 5-100 micro...

Equations of state should be tuned to reservoir conditions by PVT tests for phase behavior modeling. This tuning is achievable via an optimization method. In this work, simulated annealing algorithm is applied as a global optimization method to parameter optimization for PC-SAFT from the statistical associating fluid theory incorporating hard chain as reference fluid. The optimization parameter...

The formation of calcium phosphate phases is extremely important in a biomedical engineering context. These phosphates are used in many applications, such as grafts, drug-delivery processes and evaluation of the bioactivity of metallic surfaces. Considering this scenario, it is useful to evaluate the thermodynamic conditions for the precipitation of phosphates of biomedical interest, mainly hyd...

the use of flow cytometry in the clinical laboratory has grown substantially in the past decade. flow cytometric analysis provides a rapid qualitative and quantitative description of multiple characteristics of individual cells. for example, it is possible to detect the cell size and granularity, aspects of dna and rna content and the presence of cell surface and nuclear markers which are used ...

The application of microneedles (MNs) for minimally invasive biological fluid sampling is rapidly emerging, offering a user-friendly approach with decreased insertion pain and less harm to the tissues compared conventional needles. Here, finger-powered microneedle array (MNA) integrated microfluidic chip was conceptualized extract body samples. Actuated by finger pressure, device enables an eff...

There are many ferromagnetic particles dispersed in carrier oil in magnetorheological fluids. Assuming Newtonian motion, the forces between particles of different radius, including magnetic interaction, viscous force and contact interaction, are obtained, and the corresponding model for motion of particles is proposed. Under an external magnetic field, the microstructures in bidisperse magnetor...
