In temporal summation, two stimuli, each being too weak to excite, cause a sensation of light if presented in rapid succession on the same spot of the retina; thus, over a certain range of times, up to 0.1 second, the Bunsen-Roscoe law holds: namely, that the intensity of light multiplied by the time of exposure equals a constant.
The expansion of specimens immersed in solutions containing Na2SO4, K2SO4, MgSO4 and (NH4 2SO4 occurred in two stages within a certain range of exposure time.
The cells grown on the sterile cover slip in 6-well tissue culture plates were treated with compounds for a certain range of treatment time.
The cells were seeded at a concentration of 5 × 104 cell/mL in a volume of 0.8 mL on a sterile cover slip in 6-well tissue culture plates, and were treated with compounds for a certain range of treatment time.
The loading values (weights) provide information about the relative importance of the variables (fraction(s) of the mixture that is eluted from a chromatographic column within a certain range of elution time) into the construction of a given principal component.
In this case, stochasticity must be taken into account throughout, and interest shifts to the expected time A1 spends in a certain range of allele frequencies (sojourn time) and the expected time to extinction (absorption time).
Various cell viability assays in combination with a broad range of cell lines have shown that UCNPs with good surface treatment are nontoxic within a certain range of concentrations over a defined incubation time.
The recoil pressure effect, on the contrary, is capable of strongly decreasing the melt-through time in a certain range of laser intensity.
One possible explanation for the discrepant results is that stimulus contrast may only affect dwell times in a certain range of stimulus contrasts, near the detection threshold: Research on reading has shown that stimulus contrast only modulates dwell times when the stimulus contrast is very low, and the detectability approaches the detection threshold [9] [10] [13] [15].
Over a certain range of salinities, nanofluid can be stable for a long period of time.
