Through this comparison, it was found that the behavior was heterogeneous, as post-flight changes in concentrations were protein-dependent.
Changes in concentrations of cortisol in saliva were used to indicate serotonergic reactivity.
The axial dispersion model was applied for describing the dynamic changes in concentrations of compounds.
The changes in concentrations in reality may differ significantly from predicted ones.
Yang, X. et al. How sensitive is the recovery of stratospheric ozone to changes in concentrations of very short-lived bromocarbons?
The scientific debate about the cause of increased methane is important because it suggests that we do not yet have a good model for what determines changes in concentrations.
Changes in concentrations of metabolites or in enzymatic activity in tissues, blood, or excretory products are examined by numerous biochemical techniques.
We used 31P nuclear magnetic resonance spectroscopy to monitor noninvasively changes in concentrations of phosphocreatine [( PCr]), [Pi], [ATP], [PCr]/[PCr] + creatine ([Cr]), [Pi]/[PCr] + [Cr], and pH in the gastrocnemius muscle of subjects exercising to fatigue.
First, adequacy of the network structure is checked by global sensitivity analysis to changes in concentrations of molecular species, validating that the model can reproduce qualitative features of the system behavior derived from experiments or literature surveys.
However, the study showed changes in concentrations of nanoparticles and aggregates (operationally defined as the fraction passing a 0.2 µm filter).
It describes the volume and distribution of body water, and the water shifts and changes in concentrations of electrolytes that occur during strenuous exercise, whether brief or prolonged.
