We compare classes of finite relational structures via monadic second-order transductions. More precisely, we study the preorder C ⊑ K : iff C ⊆ τ(K) for some transduction τ. If we only consider classes of incidence structures we can completely describe the resulting hierarchy. It is linear of order type ω + . Each level can be characterised in terms of a suitable variant of tree-width. Canoni...

Bioassay of 5-nitro-o-anisidine for possible carcinogenicity.

A bioassay of 5-nitro-o-anisidine for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 5-Nitro-o-anisidine was administered in the feed at either of two concentrations, to groups of 50 male and 50 female animals of each species. The dietary concentrations used in the chronic bioassay for low and high dose rats were 0.4 and 0.8 percent, respectively. Dose A and B mi...
