The phrase "activity of the bulk" is not commonly used in written English and may be unclear without context.
It could be used in discussions related to physics, materials science, or any field where the behavior of a large quantity of material is being analyzed.
Example: "The activity of the bulk in this experiment indicates a significant reaction rate."
Alternatives: "bulk behavior" or "bulk activity".
The catalytic activity is comparable to the activity of the bulk zeolite catalyst.
On the other hand, the studies of the model supported vanadia catalysts shed new light on the origins of the catalytic activity of the bulk vanadium phosphorus oxide (VPO) catalysts for partial oxidation of n-butane to maleic anhydride.
The reductive desorption of the self-assembled monolayer of cysteine, which was formed on the Au nanoparticles-electrodeposited Au electrode, was used to monitor the change of the specific activity of the bulk Au electrode upon the electrodeposition of the Au nanoparticles.
Among these is the regulation of VH germline transcripts as so far no cis-regulatory element has been identified that controls activity of the bulk of unrearranged VH promoters.
For four corals, both the ages and the activity ratios of the bulk material and theca wall agree within uncertainty.
Collectively, based on the in vivo silencing, the biochemical analyses and platelet aggregation assays, we have calculated that the 65 kDa 5'Nuc accounts for approximately 65% of the total ATP/ADP-hydrolyzing activity and the bulk of the anti-platelet aggregation/disaggregating activity in tsetse saliva and have uncovered its fibrinogen receptor antagonistic potential.
The place for compost and other organic materials is near and on the surface of the ground, where soil has the highest biological activity and the bulk of tree feeder roots grow.
The activity was only present in the void volume (the volume of mobile phase in the column) which separated the activity from the bulk of the protein in the S100 whose mobility was retarded by the column matrix.
Serum levels, however, are unlikely to reflect adequately the intratumoral LDH activity, as the bulk of the neoplastic disease or individual variations of LDH clearance are strong confounding factors.
We emphasize that the final profiles were measured after activity had slowed dramatically, and so the lack of activity of the CDs within the bulk of the film is a true limitation of the enzyme and is not due to a slower rate or insufficient time.
Dome-collapse nuée ardente activity formed the bulk of the eruption, which was accompanied by virtually no significant vertical summit explosive activity.
