Ultrasonic detection is an effective method to quantify bubbles in opaque liquid, and acoustic scattering model the key ultrasonic inversion technique. Classical models are usually based on spherical assumption, <i>ka</i> much less than 1. However, these conditions not always satisfied practical applications. In this study, a quantitative strategy of proposed for non-spherical devia...

We have investigated two aspects of membrane traffic at early stages of endocytosis: membrane fusion and microtubule-dependent transport. As a marker, we have used the trans-membrane glycoprotein G of vesicular stomatitis virus implanted into the plasma membrane and then internalized for different times at 37 degrees C. The corresponding endosomal fractions were immunoisolated using the cytopla...

Abstract Many issues related to mass and heat transfer through beds of granular materials are still not fully understood. In this work, non-isothermal turbulent flow is analysed within layers spherical non-spherical elements. We apply a volume penalization (VP) approach formulated in the framework an immersed boundary technique (IB) on Cartesian computational meshes. It allows modelling flows a...

Several diffuse interstellar bands (DIBs) have profiles with resolved sub-peaks that resemble rotational of large molecules. Analysis these can constrain the sizes and geometries DIB carriers, especially if exhibit clear variations along lines sight probing different physical conditions. Using extensive data set from EDIBLES survey we searched for systematic in peak-to-peak separation $\lambda\...

The theory of dynamical systems and their widespread applications involve, for example, the Lane–Emden-type equations which are known to arise in initial- boundary-value problems with singularity at time t=0. main objective this paper is make use some mathematical analytic tools techniques order numerically solve reaction–diffusion equations, spherical catalysts biocatalysts, by applying Chebys...

The polarization dependence of hyper-Rayleigh scattering has been calculated for spherical domains of orientation correlated molecules. Distributions with radial or azimuthal mean polar orientation of the molecules are found that give results consistent with experimental observations, and expressions for the polarization ratios in terms of the product of correlation strength and correlated doma...
