The Potential of Isotopic Tracers for Precise and Environmentally Clean Stream Discharge Measurements

Hydrology, 2023
Accurate discharge measurement is mandatory for any hydrological study. While the “velocity” measurement method is adapted to laminar flows, the “dilution” method is more appropriate for turbulent streams.

Short-lived Nuclei in the Early Solar System: Possible AGB Sources [PDF]

, 2005
(Abridged) We review abundances of short-lived nuclides in the early solar system (ESS) and the methods used to determine them. We compare them to the inventory for a uniform galactic production model.

The temperature and chronology of heavy-element synthesis in low-mass stars [PDF]

, 2015
Roughly half of the heavy elements (atomic mass greater than that of iron) are believed to be synthesized in the late evolutionary stages of stars with masses between 0.8 and 8 solar masses. Deep inside the star, nuclei (mainly iron) capture neutrons and

Antagonistic Interaction of Selenium and Cadmium in Human Hepatic Cells Through Selenoproteins

Frontiers in Chemistry, 2022
Cadmium (Cd) is a highly toxic heavy metal for humans and animals, which is associated with acute hepatotoxicity. Selenium (Se) confers protection against Cd-induced toxicity in cells, diminishing the levels of ROS and increasing the activity of ...
