A radioactive isotope undergoing natural decay. Many others. In all these cases, the rate of change in a measured quantity (temperature, gas pressure, water height, voltage, decay rate) is proportional to the remaining distance. Before I show examples of these functions, I would like to digre...
Radiocarbon dating relies on the radioactive decay of carbon-14 (14C), a naturally occurring isotope of carbon. Carbon-14 undergoes radioactive decay by emitting a beta particle, transforming into nitrogen-14 (14N). The decay process follows exponential decay kinetics, where the rate of decay...

To avoid the above disadvantages, in this paper we propose to use the isotope parameter δ18O, which has unique conservative properties. It does not depend on chemical–biological processes and is an ideal tracer for balance estimates. The use of this parameter makes it possible to solve one ...
Campaign for water sampling was undertaken through the area for hydrochemical and isotope analysis. The selection of the sampling locations was planned to take into consideration the representative area of the basin and the presence of complex system where cold water and thermal springs are found ...
The spectra were calibrated using the 520.6 cm−1 line of a silicon wafer. The wavenumbers were accurate to ±1 cm−1. The carbon-isotopic ratios were measured using a Flash EA 1112 (Thermo Fisher Scientific, Waltham, MA, USA) coupled to a Finnigan Delta Plus XP isotope-ratio mass ...
