Ecotoxicity of nanomaterials to fish: challenges for ecotoxicity testing.

Le ar n ed D is co u rs es Intent. The intent of Learned Discourses is to provide a forum for open discussion. These articles refl ect the professional opinions of the authors regarding scientifi c issues. They do not represent SETAC positions or policies. And, although they are subject to editorial review for clarity, consistency, and brevity, these articles are not peer reviewed. The Learned ...

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

A Method to Predict and Understand Fish Survival under Dynamic Chemical Stress Using Standard Ecotoxicity Data

The authors present a method to predict fish survival under exposure to fluctuating concentrations and repeated pulses of a chemical stressor. The method is based on toxicokinetic-toxicodynamic modeling using the general unified threshold model of survival (GUTS) and calibrated using raw data from standard fish acute toxicity tests. The model was validated by predicting fry survival in a fish e...
