Photic zone euxinia during the Permian-triassic superanoxic event.
Carbon and sulfur isotopic data, together with biomarker and iron speciation analyses of the Hovea-3 core that was drilled in the Perth Basin, Western Australia, indicate that euxinic conditions prevailed in the paleowater column during the Permian-Triassic superanoxic event. Biomarkers diagnostic for anoxygenic photosynthesis by Chlorobiaceae are particularly abundant at the boundary and into ...

Synthesis and New Synthetic Utility of some (Hetero)aryl Azido Compounds under Thermal and Ultrasonic Irradiation
Some aryl and heteroaryl azido compounds were synthesized from the reaction of corresponding fluoro and chloro compounds with sodium azide in DMF as solvent and under various reaction conditions especially ultrasonic irradiation. Reaction of aromatic and heteroaromatic azido compound with thioacetic acid in the presence of sodium hydrogen carbonate and in methanol as solvent led to the differen...

15 صفحه اولRemote Sensing of Slicks as Indicators for Marine Processes in the Coastal Zone
Monomolecular surface films (“sea slicks”) are well known to dampen small-scale waves at the water surface, and thereby to influence transport processes at the air-sea interface. Because of their strong wave-damping capabilities they can often be delineated on synthetic aperture radar (SAR) imagery, but also on satellite imagery acquired in the visible and infrared spectral ranges. Since sea sl...
