the study was carried out to develop an efficient approach for prediction the genotoxicity of carbon nanotubes. the experimental data on the bacterial reverse mutation test (ta100) on multi-walled carbon nanotubes (mwcnts) was collected from the literature and examined as an endpoint. by means of the optimal descriptors calculated with the monte carlo method a mathematical model of the endpoint...

an experiment was conducted to study the effects of an emulsifier (glycerol polyethylene glycol ricinoleate: gpgr) and different sources of fat on the performance of khaki campbell ducks. ducks were assigned into five groups with three replicates (10 ducks/replicate) in each group. treatments were a control diet (c1: without added oil and emulsifier), control diet added with 2% soybean oil (c2)...
