Taxonomic and non-taxonomic responses of benthic macroinvertebrates to metal toxicity in tropical reservoirs. The case of Cantareira Complex, São Paulo, Brazil [PDF]
Anais da Academia Brasileira de Ciências, 2020 Benthic macroinvertebrates are organisms that are recognized as water quality bio-indicators. A wide variety of indices and metrics have been shown to respond to a variety of anthropogenic impacts, usually under a general condition of environmental ...

Time-reversal symmetric topological metal [PDF]
Phys. Rev. B 104, 165422 (2021), 2021 Topological metals possess gapless band structures accompanied with nontrivial edge states. Topological metals are created from the topological insulators by adjusting the magnetic flux. Here we propose the time-reversal symmetry protected topological metal without employing the magnetic flux.

Spatial metallicity variations of mono-temperature stellar populations revealed by early-type stars in LAMOST [PDF]
A&A 674, A129 (2023), 2023 We investigate the radial metallicity gradients and azimuthal metallicity distributions on the Galactocentric $X$--$Y$ plane using mono-temperature stellar populations selected from LAMOST MRS young stellar sample. The estimated radial metallicity gradient ranges from $-$0.015\,dex/kpc to $-$0.07\,dex/kpc, which decreases as effective temperature ...

Is the atomic metal vapor a dielectric state? [PDF]
Physica Scripta, 2021, 2020 We propose a simple method for calculating the metal vapor conductivity at the critical point and near-critical isotherms. This method's base is the hypothesis of an electron jellium's existence as an origin of the conduction band in metal vapor's gaseous phase. Satisfactory agreement with the experimental data for alkali metals (Cs, Rb) concludes that

Reproduction Sensitivity of Five Daphnia Species to Nickel
Journal of Water and Environment Technology, 2020 In Japan, data on the reproduction sensitivity of Daphnia magna, which is a widely used organism in laboratory toxicity tests, to nickel are key to determination of water quality target values for nickel, which are used to set values for the ...
