one of its isotopes. Formally, it is the ratio of rate constants for the reactions involving the light (kL) and the heavy (kH) isotopically substituted...

of trace elements, including carbon, oxygen and strontium. Stable isotope analysis of human and faunal hydroxyapatite can be used to indicate whether...

stress analysis and stable isotope analysis, combined with other archaeological data, seem to support this supposition. Based on stable isotope levels...

When analyzing the isotopes of the Aconcagua mummy, scientists concentrated specifically on carbon, nitrogen and sulfur. The analysis shows that in the...
