CN/CN isotope ratio and fractionation
We have detected circumstellar absorption lines of the CN and CN Violet and Red System in the spectrum of the post-AGB star HD 56126. From a synthetic spectrum analysis, we derive a Doppler broadening parameter of b = 0.51 ± 0.04 km s, CN/CN= 38±2, and a lower limit of 2000 on CN/CN and CN/CN. A simple chemical model has been computed of the circumstellar shell surrounding HD 56126 that takes i...

متن کاملAplysinopsins - Marine Indole Alkaloids: Chemistry, Bioactivity and Ecological Significance
Aplysinopsins are tryptophan-derived marine natural products isolated from numerous genera of sponges and scleractinian corals, as well as from one sea anemone and one nudibranch. Aplysinopsins are widely distributed in the Pacific, Indonesia, Caribbean, and Mediterranean regions. Up to date, around 30 analogues occurring in Nature have been reported. Natural aplysinopsins differ in the bromina...
متن کاملTesting the allometric scaling of alkaline phosphatase activity to surface /volume ratio in benthic marine macrophytes
Alkaline phosphatase activity (APA), tissue P, N and C were determined for 23 species of benthic marine macrophytes (22 macroalgae, 1 seagrass). In addition, estimates of the surface area /volume ratio (SA:V) of these species were derived from experimental work and from the literature. The tissue nutrient content (especially P) does not explain differences in APA among the species of marine mac...
