Changes in fluorescence intensity of the pH indicator in the different pH buffered solutions were observed within few seconds indicating an easy accessibility of the embedded dye by protons through the pores of the silica shell.
When the attached bead was displaced, the force applied to the focal adhesions transiently rose, and then declined in less than a few seconds, indicating a tension decline in the stress fibers, probably due to a partial destruction of the linkage among the actin fibers within the stress fiber, which would decrease its elastic modulus.
Because of the fast cervicocranial circulation the timing of carotid MRA depends on a few seconds, as indicated by this study and by others [ 9, 10].
A clear blue solution results from formation of [Cu(NH3 4(H2O)2]2+ complex after shaking the beaker for a few seconds which indicates formation of copper(I) oxide [19].
Before each problem, a yellow circle or blue square would pop up on the screen for a few seconds to indicate whether a math task or word task was coming up next.
Approximately half of the men reported an increase or no change in erections, orgasms, and time to achieve orgasms from pre-VMMC, while one-third indicated fewer erections and orgasms and decreased time to achieve orgasms post-VMMC.
However, a few seconds later, his ECG indicated severe bradycardia (HR of <30 bpm) and gradually showed prolonged R-R intervals, immediately followed by asystole (Fig. 3).
The noise level of the two horizontal components is lower than that at high-noise land stations at periods between a few seconds and 30 s, indicating that teleseismic S waves in this period range are useful.
Some years are skipped over altogether, and others are indicated by a few seconds of actions: an unanswered phone call; a dive into a swimming pool.
The color of the solution turned to brown within a few seconds, and to gray within an hour, indicating formation of Al NCs.
