Sentences with phrase «slow decay rate»

In short, your calculation is based on the exchange rate, not the decay rate and the 14C spike is of no help in this case, because that shows a mixture of slow decay rate and fast exchange rate, where the fastest is dominant.

The water drawn from Shreveport gives a slower decay rate than does water from NYNY.

Low oxygen conditions slow decay rates, resulting in much of the carbon accumulating in the soil.

Not exact matches

(In L. humile, the pheromone concentrations do decay but at a very slow rate.)

cardiomyocytes exhibit decreased peak shortening and maximal velocity of shortening / relengthening, prolonged time - to - 90 % relengthening, reduced intracellular calcium release upon electrical stimulus associated with a slowed intracellular calcium decay rate, and significantly higher oxygen levelse, and significantly higher oxygen levels

You might notice that sugar dissolves in hot water faster, or putting food in the refrigerator will slow the rate of decay.

When the oceans begin to slow the rate of CO2 uptake at saturation point that will futher push atmospheric CO2 even higher, simultaneously the massive amounts of additional CO2 and methane and nitrous oxide etc released from the decay and oxidisation of oceanic living creatures who can not survive in a low ph environment will future ram the nail in the coffin.

I agree that the multimillennial «tail» of the CO2 decay trajectory is relatively unimportant in its own right, but it is not trivial, because it affects the overall rate of decay that includes processes that occur over many decades or a few centuries involving CO2 mixing into the deep ocean and carbonate buffering, and makes them slower than they would be otherwise.

The reasons are also based on the physics, which require that initial equilibration involves the rapidly equilibrating sinks in the ocean mixed layer and some terrestrial sources, while the overall decay rate that involves slower equilibration with larger sinks is much slower.

= decay rate, and the decay rate can only be slower in the presence of incoming CO2.

Thus the observed sink rate in 14C decay is far too short, the real sink rate of the decay of an extra amount of CO2 is much slower.

The other point is very slow partial radiative decay rates of CO2 molecules were determined by experiment.

While lots of carbon cycles in and out of the atmosphere from photosynthesis and decay (most of that 95 % figure), the planet has a (comparably) very slow rate of removing carbon from the atmosphere and oceans for geological timescales — only enough to roughly cancel out volcanoes and other proportionally very small «old carbon» sources.
