Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]
, 2008 Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

Cholesterol absorption efficiency declines at moderate dietary doses in normal human subjects
Journal of Lipid Research, 1999 While unphysiologically large cholesterol doses are known to reduce percent cholesterol absorption, smaller amounts are reported to have no effect in human subjects.

Frontiers in Cellular Neuroscience, 2023 IntroductionThere is a lack of robust metabolic imaging techniques that can be routinely applied to characterize lesions in patients with brain tumors. Here we explore in an animal model of glioblastoma the feasibility to detect uptake and metabolism of ...

Cosmological Deuterium Production in Non-Standard Scenarios [PDF]
, 2002 It is widely believed that the cosmic baryon density may be obtained by inferring deuterium abundances in low-metallicity quasar absorption line systems. The implicit assumptions which enter this argument are critically assessed.

Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?
, 2012 Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.

Evolution of dispersion in the cosmic deuterium abundance
, 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.

Stable Isotopic Evidence of Paleorecharge in the Northern Gulf Coastal Plain (USA)
HydrologyStable isotope abundances (δ18O and δ2H) in regional aquifers can provide important paleoclimate information. However, identifying paleoclimate signals can be complicated by cross-formational mixing and, potentially, by isotopic diffusion between ...
