The phrase "a rapid flash" is correct and usable in written English.
It can be used to describe a quick or sudden burst of light or an event that occurs very quickly.
Example: "As the storm approached, there was a rapid flash of lightning that illuminated the sky."
Alternatives: "a quick burst" or "a swift flash".
Solid green yields to a rapid flash: prepare.
The soldiers in "Stop-Loss" have made Iraq videos, too, which are like excruciating experimental films — a rapid flash of terror and "relaxed" moments that seem only slightly less frantic than battle.
In contrast, 5 b was found to be less stable, and new red bands appeared during chromatographic purification, even when a rapid flash procedure was applied.
Programs coded in Arduino© (Arduino SA) provide the ability to run: (1) A fixed light cycle, (2) A day/night cycle with light flux changing at manually set time increments (for example, 5% every 30 min to a maximum or minimum level) to simulate outdoor solar conditions and (3) a rapid flashing light cycle to simulate mixing of cells in photobioreactors (maximum cycle speed is 10 ms−10.
The age-related U.S. children's MRI data was collected at the MCBI on a Siemens Medical System 3T Trio with a 3D T1-weighted MPRAGE RF-spoiled rapid flash scan in the sagittal plane with the following parameters: TR = 2,250 msec, TE = 4.52 ms, flip angle = 9°, FoV = 256 mm × 256 mm, matrix size = 1 mm × 1 mm × 1 mm (the sagittal dimension of the T1W ranged from 160 to 212 slices).
The residue was purified by rapid flash column chromatography on a short column of silica gel to give the oxasiloles as colourless oils, which are sensitive to silica gel.
In worms, flies and fish wounding induces a rapid calcium flash through the epithelium [ 49,50,51 ], which, in flies at least, leads to Duox activation via a pair of calcium-sensing EF hands in an intracellular loop [ 49 ].
Prior to wounding, GCaMP3 fluorescence, and hence cytosolic calcium levels, did not alter in the epithelial cells; however, laser wounding resulted in a rapid calcium flash extending outward from the point of wounding as a wave to an average maximum distance of 39 ± 4.8 μm from the wound margin (SD, n = 6 movies) at a speed of 6.9 ± 2.5 μm/s (SD, n = 7 movies) across multiple cells.
We compare biochemical variations in the cerebellum of healthy untreated rats due to preparation by three different methods: (A) decapitation into liquid nitrogen (<0.5 min PMI), (B) brain dissection followed by rapid flash freezing (2 min PMI), or (C) tissue dissection and delayed flash freezing of brain tissue (30 min PMI).
It was previously reported that rapid "flash" heating (higher temperature and shorter time) using certain ILs to pretreat biomass is more efficient with regards to the carbohydrate yield and removal of lignin [ 25].
Brains from healthy rats were prepared by one of the following three methods that incorporate different postmortem intervals (PMI), as fully described in Methods: (A) decapitation into liquid nitrogen (<0.5 min PMI); (B) decapitation and removal of the brain followed by rapid flash freezing (2 min PMI); (C) decapitation as in (B) but followed by a delay of 30 min before flash freezing (30 min PMI).
