Fish models for ecotoxicology

1. Laboratory models Fish laboratory models covering different parts of the life cycle and different routes of exposure are continuously developed and modified in order to meet new challenges. The most important exposure routes are by injection, trough contaminated water or feed [1]. For laboratory studies zebrafish (Danio rerio), medaka (Oryzias latipes), fathead minnow (Pimephales promelas) a...

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

Comparing chemical fingerprints for ecotoxicology

We present a comparison between 14 chemical fingerprints using 1D/2D features and PMCSFG, a data mining method that induces features based on maximum common subgraphs. We provide an experimental evaluation and discuss the usefulness of the different methods on ecotoxicology data. The features generated by data mining yield a similar performance for predicting toxicity, while they are more inter...

AMEG: the new SETAC advisory group on aquatic macrophyte ecotoxicology

INTRODUCTION AND BACKGROUND Primary producers play critical structural and functional roles in aquatic ecosystems; therefore, it is imperative that the potential risks of toxicants to aquatic plants are adequately assessed in the risk assessment of chemicals. The standard required macrophyte test species is the floating (non-sediment-rooted) duckweed Lemna spp. This macrophyte species might not...
