Discriminating among individuals and rejecting non-group members is essential for the evolution and stability of animal societies. Ants are good models for studying recognition mechanisms, because they are typically very efficient in discriminating 'friends' (nest-mates) from 'foes' (non-nest-mates). Recognition in
Comparison of n-eicosane and phenanthrene removal by pure and mixed cultures of two marine bacteria.

The biotransformation activities of two hydrocarbonoclastic marine bacteria, Corynebacterium sp. and Sphingomonas sp. 2MPII, on n-eicosane and phenanthrene were investigated. During a 56-day experiment, in pure and mixed cultures, Corynebacterium sp. and Sphingomonas sp. 2MPII removed about 70% of the

All six insecticide active ingredients in pyrethrum extract were quantified by supercritical fluid chromatography and carbon calibration. Allethrin is a suitable reference compound for carbon calibration and pyrethrins calibrations. Carbon quantification in SFC is also applied to pyrethroids (phenothrin, permethrin

Recently, it has been reported that n-alkanes are principal components of diesel exhaust nanoparticles. We investigated the effects of n-alkanes on the surface activity of a pulmonary surfactant monolayer using both fresh surfactant isolated from mouse lungs, and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)
