A 20-minute oscillation of erythemal UV-B solar irradiance was observed before and after the time of the eclipse maximum under clear skies, indicating a possible 20-minute fluctuation in total ozone presumably caused by the eclipse induced gravity waves.
Although vertical acoustic resonance is the most plausible mechanism of the 4-minute oscillation observed after the earthquakes, there has been no direct evidence of acoustic resonance by atmospheric pressure observations.
The magnitude of the spikes immediately decreases, and after 15 minutes all oscillations are suppressed.
However the time scale of oscillation of intracellular calcium or calcium-dependent currents is in the order of seconds to minutes, whereas oscillations in osteoclast numbers occur with the periodicity in the order of days, suggesting that the association between the two phenomena is unlikely.
At 100% oscillatory strain, all apparent moduli are below 100 Pa by the end of 5 minutes of oscillation, illustrating rapid network disruption.
After this time the non-adherent cells were re-suspended by use of a mechanical plate shaker for 5 min at 150 oscillations per minute (IKA-Shuttler MTS4; NE Lab supplies, UK).
By measuring the same location on the retina every 15 minutes, sinusoidal intensity oscillations can be observed.
While stochasticity is minimal in these species, the stochastic model of NF-κBn has qualitatively different behaviour to the quasi-deterministic model from about 500 minutes onwards; whereas oscillations die out in the quasi-deterministic model, they apparently continue in the stochastic model.
The right ankle joint was manipulated in dorsi-flexion (30 to 45 degrees) at approximately 20 oscillations per minute for 2 minutes, followed by a 25-second pause for rest.
The solution was mixed with 200 mg of 0.5 mm beads (TOMY SEIKO, Tokyo, Japan), and the cells were mechanically disrupted 10 times using a BeadSmash 12 (Wakenyaku, Kyoto, Japan) at 4°C, 4,000 oscillations per minute for 1 min.
