The peak of journal articles occurred in 2005, with an increasing ratio over time of technical recommendations to research work.
The change in the titrant to dispersant concentration ratio over time thus provides an indirect measure of ambient OH.
M118 a novel, rationally engineered heparin provides consistent anti-Xa and anti-IIa activity with a constant anti-Xa:anti-IIa ratio over time.
Bulk degradation of acellular hydrogels was confirmed by a decrease in compressive modulus and an increase in mass swelling ratio over time.
Here, an essentially rubidium-free, strontium-rich phase like apatite retains its initial 87Sr/86Sr ratio over time, whereas the value in such rubidium-rich, strontium-poor minerals as biotite increases rapidly with time.
Increases and decreases in the value of the underlying stocks and bonds will move the stock-to-bond ratio over time, and you may need to adjust your holdings accordingly, but that is the only additional work you need to do.
As a result, two parameters that represent a change in electrical resistivity are identified: the rising time, which indicates the onset of an increase in electrical resistivity, and the increasing ratio over time.
As expected, H2O2 (0.2 mM) exposure disrupted cellular glutathione homeostasis in both HepG2 cells (a human hepatoma cell line) and NCTC1469 cells (a non-transformed mouse hepatocyte cell line), as demonstrated by an increase in the GSSG/GSH ratio over time (Fig. 2a, b), which was comparable to that observed in the livers of HFD-fed mice (Fig. 1f).
But if that was the only factor, you'd expect to see the same ratio over time.
But what is equally surprising is the consistency of that ratio over time.
