Not exact matches

You do not know how or when the carbon molecule was created, nor do you know whether the rate of decay was constant (you assume it instead) because you can not measure the conditions in the past.

«The radionuclide ratios we measured in the sediments and the rates of decay and growth of radioactive elements in the impacted sediments allowed us to essentially age - date the contamination to after 2011,» she explained.

This is a routine bookkeeping style of research: According to known physics, this type of radioactive decay is a fundamental process that unfolds at an unchanging rate, and all the researchers were aiming to do was to measure that rate and record it for reference.

Specifically, NA62 will measure the rate at which the charged kaon decays into a charged pion and a neutrino - antineutrino pair.

Krypton dating is much like the more - heralded carbon - 14 dating technique that measures the decay of a radioactive isotope — which has constant and well - known decay rates — and compares it to a stable isotope.

According to Strassler, the Higgs mass problem could be a sign that we should not trust the unusually high rate of photon decays measured.

Since the rate of these decays depends on how massive neutrinos are, this would be a roundabout way of measuring neutrino masses, which has never been done.

Experiments that measure the rate of antineutrino production from the decay of uranium and plutonium isotopes have so far produced results roughly consistent with this theory.

As well as the masses of these particles, the research team studied their relative production rates, their widths - a measure of how unstable they are - and other details of their decays.

Options are wasting assets, and theta measures the rate of decay.

It is easy to calculate the time constant of the decay rate of the extra volume, because that is in linear ratio with the increase in height of water in the tank, and we know the extra outflow at the measured increase.

The decay rate can be derived from the measured increase in volume and calculated outflow (s), which is a highly linear system, independent from the exchange rates or reservoir sizes.

All original human CO2 is gone in about 60 years, while still about 10 % of the original peak in CO2 (100 % caused by humans) is measurable after 160 years... The measured response of the ocean - atmosphere carbon cycle in 1988 at 350 ppmv (60 ppmv above steady state) gives an e-fold decay rate of ~ 55 years: http://www.john-daly.com/carbon.htm» ANSWER: What is to be considered is the simple problem (the equation at the top of this reply) constrained by the four monthly time series (CO2)(t) and its delta13C (t), f anthropic (t) and its delta13C (t).
