Development of an open source Debris Flow Simulator for “Sabo” (DFSS) [PDF]

E3S Web of Conferences, 2023
We report the development of an open source “Debris Flow Simulator for Sabo” (DFSS). DFSS consists of three models corresponding to three geomorphological regions (mountain hillside slopes, mountain-to-plain river channels, and lower plains).

Lethal, behavioral, growth and developmental toxicities of alkyl-PAHs and non-alkyl PAHs to early-life stage of brine shrimp, Artemia parthenogenetica

Ecotoxicology and Environmental Safety, 2021
Alkyl-PAHs are the predominant form of PAHs in crude oils which are supposed to demonstrate different toxicities compared to non-alkyl PAHs. Little information is available about the toxicity of alkyl-PAHs on marine Artemia.
