Abstract
Research into fingermark enhancement techniques has traditionally used visual comparisons and qualitative methods to assess their effectiveness based on the quality of the developed fingermark. However, with increasing research into the optimisation of these techniques the need for a quantitative ev...

Abstract
Azo dye are recalcitrant pollutants. Two sulfonated azo dyes, Orange II and Amino black, are effectively decolorized by certain noncardioform strains of the genus Rodococcus. A mutant of one of these strains was isolated which had lost azo-dye decolorizing ability and the strain was used to clone DNA...
