The variety of methodologies used for sample preparation, analytical techniques, duration of exposure and post-exposure monitoring may account for these discrepancies.
To reduce pre-design stages duration, analytical models are often preferred.
Analytical expressions for the duration of the ATP cycle, for the Gibbs free energy and for the net displacement of the myosin head are obtained.
In addition to analytical limitations discussed, the duration of placebo control in trials contributing data to these analyses was relatively short.
In a query test analytical queries were executed for duration of 20 min.
The lowest two test concentrations were not within the measurable range of the photometric analytical method for the entire duration of the study and were not included in estimating EC50 values.
After including the duration in the analytical models, no independent effect was observed for age at first use, or for time since the first or last use.
The following clinical and analytical measurements were collected: DM2 duration, arterial pressure (average of the last three determinations), drugs taken by the patient at the time the data were collected (antidiabetic, antihypertensives, hypolipemiant, antiplatelet, and anticoagulants).
In particular, reproducibility of performances, repeatability of analytical signals, lifetime, temperature limit and duration of the measurement cycle were examined, and elements available for determination justified.
An analytical model for link and path duration in mobile ad-hoc networks has been proposed in [27].
