Solute transport through homogeneous media has long been assumed to be scale-independent and can be quantified by the second-order advection-dispersion equation (ADE). This study, however, observed the opposite in the laboratory, where transport of CuSO4 through relatively homogeneous silica-sand columns exhibits sub-diffusion growing with the spatial scale. Only at a very small travel distance...

‎let $g$ be a group with identity $e.$ let $r$ be a $g$-graded‎ ‎commutative ring and $m$ a graded $r$-module‎. ‎in this paper‎, ‎we‎ ‎introduce several results concerning graded classical prime‎ ‎submodules‎. ‎for example‎, ‎we give a characterization of graded‎ ‎classical prime submodules‎. ‎also‎, ‎the relations between graded‎ ‎classical prime and graded prime submodules of $m$ are studied‎.‎

let  be a graded ring and  be a graded -module. we define a topology on graded prime spectrum  of the graded -module  which is analogous to that for , and investigate several properties of the topology.

A special study on the interaction mechanism between flow and soil is of great significance for revealing macro breaching barrier dams. To scouring characteristics wide-graded sediment under different conditions, flume scour tests were conducted regarding grading curve dam material discharge process Tangjiashan dam. The results show that: (1) narrow-graded or uniform sediments formation movemen...

Almost transitive superreflexive Banach spaces have been considered in [7] (see also [4] and [6]), where it is shown that such spaces are uniformly convex and uniformly smooth. We prove that convex transitive Banach spaces are either almost transitive and superreflexive (hence uniformly smooth) or extremely rough. The extreme roughness of a Banach space X means that, for every element u in the ...

The purpose of this paper is to consider an iterative method for an equilibrium problem and a family relatively nonexpansive mappings. Weak convergence theorems are established in uniformly smooth and uniformly convex Banach spaces.

Inhomogeneous materials, variable foundations, non-uniform cross-sections, and non-uniformly distributed loads are common in engineering structures typically complicate their mechanical analysis considerably. This paper presents an accurate efficient numerical method for the dynamic of functionally graded beams resting on inhomogeneous viscoelastic foundations subjected to moving load investiga...

The mechanical properties of pavement materials are crucial to the design and performance flexible pavements. One most commonly used measures these is resilient modulus (Er). Many different models were developed predict coarse soils, which based on states stresses physical soil. unconsolidated unsaturated drained cyclic triaxial tests performed for three variously graded well-graded sand specim...
