In vitro, in particular, particles precipitate over time, which can alter the cellular reactions depending on the precipitation rate.
The stock solutions were unstable at room temperature, forming a thick nontransparent precipitate over time.
Experimentally, we observed that suspending such particles in water resulted in immediate aggregation as well as slow oxidation, which was indicated by the formation of an amorphous white precipitate over time.
Finally, abrupt abstinence in a desensitized state may unleash the craving and precipitate any accompanying withdrawal symptoms, which may subside over time as the reward system gradually re-sensitizes.
The results also showed that internal hydrodynamics may change over time as a consequence of physical-chemical phenomena occurring in the filter, including accumulation of precipitates, slag hydration and carbonation, and particle segregation.
"People change over time.
In October 1988 he paid just under $3bn for TV Guide and precipitated his worst time.
Samples were shaken occasionally to ensure an even distribution of NMIA in the solution because NMIA is only slightly soluble in H2O and would precipitate at the bottom over time.
Over time, this precipitates other evolutionary changes in the island population, and they evolve into a separate species from the mainland flies.
Over time they can precipitate a little bit.
Soon after the addition, a yellow precipitate formed which slowly dissolved over time with stirring (can take over 24 h to dissolve).
