Changes in the plasma cortisol concentration with time under the four experimental conditions.
Changes in the plasma ACTH concentration with time under the four experimental conditions.
In that case, however, it is necessary to monitor changes in the concentration with time.
The aging under air and evolution of reactive amine surface concentration with time under air are also presented.
The theoretical model proposed is able to reasonably predict the evolution of dissolved oxygen concentration with time of cultivation.
However, since stress should have also increased the plasma ACTH levels, the decrease in plasma cortisol concentration with time is most likely due to the normal circadian pattern of the hormone.
The absence of changes in ACTH concentration with time may indicate that the circadian ACTH peak ends earlier than the circadian cortisol peak for both LR and HR subjects.
For transport experiments, however, where the changes in the local macromolecule concentration with time are measured, a reference buffer intensity is not necessarily required.
By analogy, the evolution of the oxygen concentration with time was demonstrated to be characterized by the law of inverse gamma.
Kinetic analysis of the change of herbicide concentration with time during electrolysis, determined by high-performance liquid chromatography, revealed that all compounds follow a pseudo first-order reaction.
A zero-order degradation rate of naphthalene of 5 μg/L-day was estimated based on the decrease in 14C-naphthalene concentration with time.
