One Percent Determination of the Primordial Deuterium Abundance [PDF]
, 2017 We report a reanalysis of a near-pristine absorption system, located at a redshift toward the quasar Q1243+307, based on the combination of archival and new data obtained with the HIRES echelle spectrograph on the Keck telescope.

Revista Facultad de Ingeniería, 2018 Identifying the hydraulic connection between the area of recharge and the area of discharge in aquifers is only possible by using tracers; the 18O and 2H isotopes have proven to be good tracers to determine such hydraulic connection.

Preparation of intravenous cholesterol tracer using current good manufacturing practices1
Journal of Lipid Research, 2015 Studies of human reverse cholesterol transport require intravenous infusion of cholesterol tracers. Because insoluble lipids may pose risk and because it is desirable to have consistent doses of defined composition available over many months, we ...

Measuring the Primordial Deuterium Abundance During the Cosmic Dark Ages [PDF]
, 2005 We discuss how measurements of fluctuations in the absorption of cosmic microwave background (CMB) photons by neutral gas during the cosmic dark ages, at redshifts z ~ 7--200, could reveal the primordial deuterium abundance of the Universe.

Deuterium-burning in substellar objects [PDF]
, 2000 We consider the depletion of primordial deuterium in the interior of substellar objects as a function of mass, age and absolute magnitude in several photometric passbands.
