The transport and deposition of fine particulate organic matter (FPOM) is an important flux linking upstream and downstream reaches of stream ecosystems. However, few studies have attempted to identify physical controls on particle transport. One reason has been the lack of relatively simple, inexpensive methods. We describe a new technique for measuring fine particle transport in streams using...

The mechanism of conversion from the kinetic energy of electron beams to electromagnetic wave energy is investigated in the two-stream amplifier. It is shown that the optimal efficiency of the amplifier scales according to AV/V for relativistic electron beams and (AV/V) 2 for nonrelativistic electron beams, where AV is the axial velocity difference in the two beams and V is the mean axial beam ...

narration is a cognitive tool to understand the experience flow and the theses of analysis of stream of consciousness is considered as one of the most recent and popular methods of analyses of literary works. in the stream of consciousness method, for a detailed and momentum description, the content of thought has a central function and appears in the form of narrative tips and techniques like ...

Stellar streams produced from dwarf galaxies provide direct evidence of the hierarchical formation Milky Way. Here, we present first comprehensive study LMS-1 stellar stream, that detect by searching for wide in Gaia EDR3 data set using STREAMFINDER algorithm. This stream was recently discovered Yuan et al. We as a 60° long to north galactic bulge, at distance ∼20 kpc Sun, together with additio...

This study attempts to analyze the effect of diverse parameters peristaltic flow second grade dusty fluid through a curved configuration. Stream function conversions are used model separate system equations for dust particles and fluid. The Perturbation technique is get analytical solutions results verified graphs. It noticeable that trapped bolus, compresses both with an increase in `the param...

A systematic way to derive the conserved quantities for the axisymmetric liquid jet, free jet and wall jet using conservation laws is presented. The flow in axisymmetric jets is governed by Prandtl’s momentum boundary layer equation and the continuity equation. The multiplier approach is used to construct a basis of conserved vectors for the system of two partial differential equations for the ...

To investigate the translation of a compound particle in a highly viscous, incompressible fluid, we carry out an analytic study on flow past a fixed spherical compound particle. The spherical object is considered to have a rigid kernel covered with a fluid coating. The fluid within the coating has a different viscosity from that of the surrounding fluid and is immiscible with the surrounding fl...
