In studying environmental hazards, one needs to test mixtures of many chemicals, across ranges of doses, at different points in time, and at different ages, from conception to childhood to old age.
The ranges of dosing timings that induce the stable entrainment become narrower as day length increases.
Second, over wide ranges of doses there is weak evidence only of dose-responsiveness with these drugs.
The applied approaches used to study the dose response relationship differ between showing average effects for ranges of doses and establishing continuous dose response functions.
Hospital C also had the narrowest range of dose values for all CT regions (Figs. 1, 2, 3, 4 and 5).
Samples pre-irradiated in air and subsequently graft polymerised yielded higher values of crystallinity in the entire range of dose and concentration of inhibitor.
For the range of dose rates examined, no measurable dose rate effect on tensile properties was noted for any of the steels.
Data show the vaccine is safe in people, including in a West African population and in a range of dose levels, GSK said.
Although the best fit curves showed maximum efficiency as dose fraction ratio approached 50%, the effect was essentially flat within a wide range of dose fractions, from 10 20 to 80 90%.
