The traditional load identification method is not sufficiently accurate because of the high computational complexity and small load data of specific customer. A depth identification method for a power fingerprint based on the transferability of the V-I trajectory is proposed. First, the method...

In this work, magnetic S-doped Fe-Cu-La trimetallic oxides (S-FeCuLaO) was prepared and adopted as a adsorbent to remove Cr(VI) from aqueous solutions. The S-FeCuLaO material was characterized by SEM, XRD, FTIR, XPS and VSM, and batch adsorption experiments were employed to investigate to the...

On the basis of hollow polymer microspheres as cavity-containing microcontainers, the reactive oil phases, consisted of monomers, cross-linked monomers, fluorinated monomers and initiators, were absorbed into its cavity under the principle of like dissolves like, afterwards obtaining loaded...

This paper utilizes the city-level variation in housing prices in the U.S. to test whether the effect of sibship size on firstborns' educational attainment is different for homeowner and renter households during the housing bust from 2007--12. To solve the potential endogeneity problem, we use...

Constructed wetlands are extensively applied in waste water treatment and water ecosystem restoration. However, the accumulation and migration characteristics and potential ecology risks of heavy metals, particularly in a long-running large-scale constructed wetland for wastewater treatment, are...
