For induction of the Ah promoter, mice received interperitoneal injections of 80 mg/kg β-napthoflavone (βNF; Sigma) dissolved in corn oil (8 mg/mL) at the frequencies stated and controls received either no treatment or corn oil only.
With greater frequency, state and industry officials are being made aware of citizen concerns through environmental organizations, like the Powder River Basin Resource Council, which are beginning to organize protests.
Two periodic states of an elastic flag are firstly identified with different dimensionless bending stiffness: a lower frequency state and a higher frequency state.
The fractional Kelvin Voigt type viscoelasticity produces complex effects on the lower frequency state.
When the fractional Kelvin Voigt model is used, the increasing α also causes the transition from the higher frequency state to the lower frequency state, and quasi-periodic states are observed during the transition.
When the Scott Blair model is used, with the increase of the fractional derivative order α, the flag flapping frequency of the higher frequency state decreases abruptly, and that of the lower frequency state also shows a downward trend.
At the global scale, "[a]ttacks on universities and colleges are occurring with alarming frequency," Quinn stated in the release announcement.
Answers were accepted if they were "none" or at least of a lower frequency than stated in the package leaflet.
If you are asked to switch to a different, radio frequency, clearly state the new frequency you are switching to and state, "If no contact in xx seconds (usually 30 seconds), return to this frequency".
Furthermore, the passenger demand of metro systems increases with the increasing of train frequencies as stated in [16, 17, 18].
