Analysis of precipitation and recharge of aquifers in Tota and Ibagué (Colombia) from stable isotopes (18O and 2H)

open access: yesRevista 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.

Tracking The Post-BBN Evolution Of Deuterium [PDF]

open access: yes, 2009
The primordial abundance of deuterium produced during Big Bang Nucleosynthesis (BBN) depends sensitively on the universal ratio of baryons to photons, an important cosmological parameter probed independently by the Cosmic Microwave Background (CMB ...

The Deuterium-Burning Mass Limit for Brown Dwarfs and Giant Planets

open access: yes, 2010
There is no universally acknowledged criterion to distinguish brown dwarfs from planets. Numerous studies have used or suggested a definition based on an object's mass, taking the ~13-Jupiter mass (M_J) limit for the ignition of deuterium.

Muon capture in deuterium [PDF]

open access: yesNuclear Physics A, 2010
Model dependence of the capture rates of the negative muon capture in deuterium is studied starting from potential models and the weak two-body meson exchange currents constructed in the tree approximation and also from an effective field theory.

Coincidence charged-current neutrino-induced deuteron disintegration for $^2\mathrm{H}_2{^{16}}\mathrm{O}$ [PDF]

open access: yes, 2017
Semi-inclusive charge-changing neutrino reactions on targets of heavy water are investigated with the goal of determining the relative contributions to the total cross section of deuterium and oxygen in kinematics chosen to emphasize the former.

Polarized light ions and spectator nucleon tagging at EIC [PDF]

open access: yes, 2014
An Electron-Ion Collider (EIC) with suitable forward detection capabilities would enable a unique experimental program of deep-inelastic scattering (DIS) from polarized light nuclei (deuterium 2H, helium 3He) with spectator nucleon tagging.

Molecular recognition in olfaction

open access: yesAdvances in Physics: X, 2017
The mechanism by which the chemical identity of odourants is established by olfactory receptors is a matter of intense debate. Here we present an overview of recent ideas and data with a view to summarising what is known, and what has yet to be ...

Effects of deuterium oxide on cell growth and vesicle speed in RBL-2H3 cells [PDF]

open access: yesPeerJ, 2014
For the first time we show the effects of deuterium oxide on cell growth and vesicle transport in rat basophilic leukemia (RBL-2H3) cells. RBL-2H3 cells cultured with 15 moles/L deuterium showed decreased cell growth which was attributed to cells not ...

Evolution of dispersion in the cosmic deuterium abundance

open access: yes, 2016
Deuterium is created during Big Bang Nucleosynthesis, and, in contrast to the other light stable nuclei, can only be destroyed thereafter by fusion in stellar interiors.
