Fluorescent Modifications of Transfer Ribonucleic Acids
… This compound has been characterized by ultraviolet, fluorescence, and nuclear magnetic resonance spectroscopy. We have shown that reaction of MMDA with E. coli tRNA('Phe) occurs and that, at least to some extent, products with fluorescent properties similar to those of (mu)-guanosine are …

The development and application of statistical sampling regime to map out hydrocarbons in sediments.
… to the samples included: laser granulometry; ultraviolet fluorescence; gas chromatography using mass-selective detection or flame ionisation detection; elemental analysis. The total PAH concentrations (2- to 6-ring parent and alkylated PAHs, including the 16 US EPA PAHs) in sediments were …

Photoionization and excitation of free variable size van der Waals clusters in the inner shell regime
… of a jet expansion. The emission of ultraviolet fluorescence radiation from variable size argon clusters is investigated with high spectral resolution in the Ar 2p-excitation regime. The fluorescence excitation spectra reveal strong fluorescence intensity in the Ar 2p-continuum, but …

Diagnostic techniques for detecting exposure and anemia in birds exposed to crude oil
… evaluation of and under the application of ultraviolet light to individual birds potentially exposed to oil. I found that there were many individual birds with modest oil exposure, demonstrating that more birds are exposed to oil than are accounted for by mortality estimates. Additionally, I …
