Isotopic shifts

The W isotopic compositions have been investigated within the classical approach to the sprocess nucleosynthesis. The Maxwellian averaged neutron capture cross-sections (MACS) adopted in the calculation are obtained from the TALYS-1.9 code with four nuclear level density models: the constant temperature plus Fermi gas, the back-shifted Fermi gas, the generalised superfluid, and the microscopic method of Goriely.

The SIAR model, on the other hand, identified fishes, fish eggs, and invertebrates with mean contributions of 35%, 30%, and 16%, respectively. Invertebrates were also an important food source for S. lucioperca during this season according to Bugalho et al. (2008). In conclusion, this study showed that S. lucioperca shifted its diet from invertebrates, including crayfish, during spring, to fishes during autumn, a result also supported by the increase in the trophic position of S. lucioperca from spring to the autumn. This study is the first to report results on the food content of S.

15N labeled soluble metallo- and metal-free phthalocyanines are described for the first time. The complexes were synthesized starting from phthalic anhydride derivatives using 98% 15N enriched urea. The effects of the substitution pattern, aggregation, and coordinated metal on 15 N chemical shifts in liquid state NMR were studied.

The distribution of selected shallow-benthic biota at circum-Tethyan carbonate platforms demonstrates an excellent proxy for the impact of latitudinally controlled cooling and variations in the trophic resources during the Palaeogene. In this study, we link and compare the spatial distribution and abundance of larger benthic foraminifera and hermatypic corals of Tethyan carbonate successions with new records from the Prebetic platform in SE Spain.
