Another para-hydroxylated metabolite, 4-HO-BDE-42, appears to have been more potent than DE-71, but because of limited availability of this compound, the analysis was not carried out with a sufficient span of concentrations to allow an accurate estimate of the EC50.
The solutions span a range of concentration 0.03 wt.% < c < 0.6 wt.%, encompassing the dilute to semi-dilute regimes and providing a range of fluid viscosities and relaxation times such that we achieve a range of Weissenberg numbers (8.7 < Wi < 1562) and Reynolds numbers (0.07 < Re < 11.2), giving elasticity numbers between 31 < El < 295.
Digital culture was always supposed to fragment our attention spans, eroding our powers of concentration with addictive interruptions and bite-sized stimuli – and it often does.
In the framework of a comprehensive study of the ceramic feedstocks in molten conditions, the viscoelastic behavior of zirconia-filled polymers has been studied over a broad span of particle concentrations (from 0 to 42 vol% i.e., from 0 to 82 wt%).
The spanning of ambient concentrations external to the chamber during logging was performed to reduce the incidence of leaks between the chamber and the outside atmosphere and represents the best estimate of flux with the minimum leakage error [ 33].
If you're not sure what is age appropriate for your child, ask the entertainer for his or her thoughts; they will be able to tailor their activities to the age group, as well as taking into account the concentration spans of the relevant age group.
9. Is your attention span shorter and your power of concentration lessening?
The experimental program spans a concentration range of 5000 to 25 000 ppm for NaCl solution and of 5000 to 20 000 ppm for MgCl2 solution at pressures covering the range of 2 9 bars.
Twelve to 18 different concentrations of pure NCXCL-SAC fusion proteins, ranging from 10 pM to 20 μM, were applied spanning a range of concentrations ten times both above and below the expected KD value.
Twelve to 18 different concentrations of pure NCXCL-SAC fusion proteins, ranging from 10 pM to 2 μM, were applied spanning a range of concentrations ten times both above and below the expected KD value.
50 nmol/l concentrations were used in some calculations to span the range of concentrations reported in vivo.
