The goal of this study is to determine the efficacy plants in treatment municipal wastewater (MWW) utilizing aquatic plant common reed, also known as Phragmites australis. Two glass basins with dimensions (60 cm x 26 cm) and a height have been developed for purpose (30 cm). In investigation, two were employed: one served reference, while other was used conduct tests using synthetic actual city ...

Abstract The thermal shock of subsurface material with shear instability and severe plastic flow during scuffing was investigated. damage M50 steel tested using a high-speed rolling—sliding contact test rig, the transient temperature calculated Fourier transform method considering effects both frictional heat work. results show that rapid rise subsequent decrease in is generated layers. power i...

We report on a newly discovered bifurcation that occurs in dry grains flowing down a chute with a wavy bottom. We find that the bifurcation outwardly resembles the long-know fluid analog of inviscid channel flow over a wavy bottom reported in 1886 by Lord Kelvin, however in detail the two situations differ significantly. We compare three distinct states seen in the granular system: a ‘regular’ ...

An algorithm utilizing measured temporal tritium ( H) variation in selected Piedmont basins is 3 developed for the computation of subsurface residence times of shallow ground water comprising stream base flow. This algorithm accounts for the effects of radioactive decay, the mixing of shallow subsurface water with precipitation, and ground-water flux to streams (base flow). The input data requi...
