Quantitative variations in ovarian follicles of female Sprague Dawley rats after exposure to low dose gamma radiation [PDF]

, 2014
In the present experiment, an attempt was made to assess the genetic risk of low dose radiations in mammals. For this purpose female Sprague Dawley rats, 11-12 weeks old, were irradiated with whole body Co 60 gamma rays in three fractionated doses of 0 ...

Radiocarbon dating of deep-sea corals [PDF]

, 2002
Deep-sea corals are a promising new archive of paleoclimate. Coupled radiocarbon and U-series dates allow ^(14)C to be used as a tracer of ocean circulation rate in the same manner as it is used in the modern ocean.

Tritium Behavior from Vine to Wine

Applied Sciences
The hydrogen radioactive isotope, tritium, not only reflects seasonal variation in precipitation but also variations on a local level. To use this radioisotope in authentication and geographical indication procedures, the tritium levels in vines, grapes,

Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary [PDF]

, 2014
The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. Although equatorward migration of the

Comparison of DeePMD, MTP, GAP, ACE and MACE Machine‐Learned Potentials for Radiation‐Damage Simulations: A User Perspective

Advanced Intelligent Discovery, EarlyView.
The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Migration of tritium in the components of the natural environment

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Formulation of the problem. Tritium formed as a result of natural or man-made processes is included in migration flows depending on the forms of its presence – gaseous (NT), aqueous (NTO) and organically bound (OZT).
