BACKGROUND AND AIMS Nuclear DNA content (C-value) varies approximately 1000-fold across the angiosperms, and this variation has been reported to have an effect on the quality of AFLP fingerprints. Various methods have been proposed for circumventing the problems associated with small and large genomes. Here we investigate the range of nuclear DNA contents across which the standard AFLP protocol...

Naphthenic acids and TAN are one of the ever-increasing crucial problems in oil, shale oil and sand oil industry and also environment protection. Furtherer, they increases the corrosion of some parts of a refinery and transport pipelines and also can create nanoemulsions and make complicated the refining process especially in desalters. To prevent these problems it is important to first obtain ...
