The phrase "a rapid light" is correct and usable in written English.
It can be used to describe a light source that emits brightness quickly or with intensity, often in a poetic or descriptive context.
Example: "The fireflies danced around us, their bodies emitting a rapid light that flickered in the warm summer night."
Alternatives: "a swift glow" or "a quick beam".
To record rapid light curves a surface holder "DIVING-SH" was fixed on the sponge.
While the government has ambitious plans to build new roads and bypasses for the city, and even establish a mass rapid transit system and rapid light rail by 2030, progress, like the traffic itself, seems painfully slow.
Light utilisation inefficiency and rapid light attenuation within a mass culture due to high pigment optical density of wild type strains have been proposed as major limiting factors reducing solar-to-biomass conversion efficiency.
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.
Rapid light curves were measured using a pre-installed software routine where actinic irradiance was increased in 10 steps from 11 to 218 µmol photons m−2 s−1 for a duration of 20 s per step.
Healthy samples were dark-adapted for 15 min; after which actual PSII efficiency (yield II) and rapid light curves (RLC) were measured using a Water-PAM chlorophyll fluorometer with Water-EDF Fiberoptics-Emitter-Detector Unit (Walz, Effeltrich, Germany).
In this study, two photophysiological assessment techniques: Diurnal Yield and Diurnal Rapid Light Curve (RLC) were investigated in an attempt to incorporate the temporal and spatial scales of sampling into a physiological assessment of Thalassia testudinum in Florida Bay.
Leaves were darkened with a leaf clamp for 15 min prior to measurements, and rapid light curves were measured using pre-installed software to estimate the relative efficiency of photon conversion (quantum yield) at low irradiances (ΦPAM), the light saturation point (Ik,PAM, µmol m−2 s−1) and the maximum electron transport rate (ETRmax, µmol m−2 s−1).
Rapid light curves (RLC's) were used to show a strong positive correlation between rETRmax of photosystem II and the incorporation of radio-labelled carbon into host tissues in juvenile A. millepora with type D and C1 symbionts [12].
Rapid light curves (Ralph and Gademann 2005), the illumination of a sample with increasing light intensities, were measured to estimate the photosynthetic performance.
