Box Models of Volatile Cycles over the Entire Phanerozoic [PDF]
, 2006 Three stand-alone geochemical box models have been developed to simulate globally coupled biogeochemical cycles. These models reflect the evolution of the participating biotic and abiotic constituents in marine and terrestrial environments, including the

Spectroscopy of $^{87}\text{Sr}$ triplet Rydberg states
, 2018 A combined experimental and theoretical spectroscopic study of high-$n$, ${30 \lesssim n \lesssim 100}$, triplet $\text{S}$ and $\text{D}$ Rydberg states in $^{87}\text{Sr}$ is presented. $^{87}\text{Sr}$ has a large nuclear spin, ${I=9/2}$, and at high-$

Gristhorpe Man: an Early Bronze Age log-coffin burial scientifically defined [PDF]
, 2010 A log-coffin excavated in the early nineteenth century proved to be well enough preserved in the early twenty-first century for the full armoury of modern scientific investigation to give its occupants and contents new identity, new origins and a new ...

Strontium Isotope Effects in Ligand Exchange Reaction [PDF]
Journal of Nuclear Science and Technology, 2002 Strontium isotope effects in ligand exchange reaction were investigated. Strontium chloride was extracted into dicyclohexano-18-crown-6/chloroform from the aqueous phase of 4–9MHCl/H2O. The distribution ratios of strontium increased with HCl concentrations.

Lead (Pb) Isotope Baselines for Studies of Ancient Human Migration and Trade in the Maya Region. [PDF]
PLoS ONE, 2016 We examined the potential use of lead (Pb) isotopes to source archaeological materials from the Maya region of Mesoamerica. The main objectives were to determine if: 1) geologic terrains throughout the Maya area exhibit distinct lead isotope ratios ...
