The phrase "activity of the stream" is correct and usable in written English.
It can be used to describe the actions or behaviors occurring within a stream, often in a scientific or environmental context.
Example: "The activity of the stream was observed to increase significantly after the rainfall, leading to a rise in water levels."
Alternatives: "behavior of the stream" or "dynamics of the stream".
The 3H activities of the stream water were between 1.26 and 1.99 TU, which are lower than those of local rainfall (2.6 to 3.0 TU).
Weyerhaeuser was building a wood stringer bridge across a Class 1 stream and my job was to make sure we disturbed the stream bank as little as possible and kept the machine activity out of the stream channel.
Possibly reflecting different functional components, the P600 has been proposed to index activity of the combinatorial stream of language processing that is sensitive to both morphosyntactic and semantic anomalies (Kuperberg, 2007), but it could also reveal engagement of a conflict-monitoring process within the executive system (Kolk & Chwilla, 2007; Vissers, Chwilla, & Kolk, 2006).
As depicted in figure 5D, neither the activity of the up-stream caspases-8 or -9, nor the activity of the central executor caspases-3 was induced by 100 µg/ml Gal-4, a dose sufficient to induce T cell apoptosis (Fig. 5B).
When William James appraised kinds of mental activity in the stream of consciousness (including their embodiment and their dependence on habit), he too was practicing phenomenology.
These ice export events occur at ∼12.9, ∼15.6, ∼22 and 29.8 ka (14C yr BP) and we argue that they record vigorous episodes of activity of the M'Clure Strait Ice Stream.
Activity: This is the stream of actions being performed by users you follow, such as when they follow someone, favorite a tweet or add someone to a list.
The combined increase in the level of (SH 2Trx-ASK1 complex and corresponding decrease of free ASK1 may account for the decreased activity of down stream targets and be indicative of their resistance to oxidative stress.
The increased activity of the high-speed plasma streams on the descendant phases of the cycles, regardless of their solar sources, proves the existence of some special local conditions of the solar plasma and the magnetic field on a large scale that allow the ejection of the high energy plasma streams.
Early studies of plant-pathogen interactions documented an increase in the activity of cytoplasmic streaming and accumulation of cytoplasm beneath the invading pathogen cell as the first structural manifestation of the response of plants to microorganisms on their surface [ 1- 4].
