The new method proposed in this work not only measures the particle size distribution and the average molar mass accurately using the static light scattering (SLS) technique when the Rayleigh-Gans-Debye approximation is valid for dilute poly-disperse homogenous spherical particles in dispersion, but also enables us to have insight into the theoretical analysis of the dimensionless shape paramet...

This paper presents the application of the method of generalized differential quadrature (GDQ) for the analysis of hydrodynamic thrust bearings. GDQ is a simple, efficient, high-order numerical technique and it uses the information on all grid points to approach the derivatives of the unknown function. The effectiveness of the solution technique is verified by comparing the GDQ computed results...

background and aims: adenovector gene transfer induces inflammatory response that finally leads to vector removal from delivered site. the effect of hydrodynamic pre-injection on adenovector mediated liver inflammation remained elusive. materials and methods: different mice groups were pre-treated by hydrodynamic saline, dexamethasone or nothing prior to adeno-luciferase administration. their s...

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

We present some results on the mathematical analysis of kinetic equations for modelling transport processes in semiconductors. We focus our attention on the connection between the kinetic models and the fluids ones based on driftdiffusion or hydrodynamic equations. Asymptotic analysis gives hydrodynamic coefficients in, terms of microscopic quantities and allows to derive accurate boundary cond...
