At the maximum effective elevation to engage surface targets, 45 degrees, the guns could hit targets up to 17,392 yards (15,903 m) away.
When the guns were used to engage surface targets, they could hit targets 17700 m away, at an elevation of 45 degrees.
This enabled to engage surface receptors in well-defined molecular and mechanical conditions.
We propose that the responsiveness of macrophages to weak stimuli is regulated by a signaling checkpoint in which degradation of LynA occurs when weak or low-valency ligands engage surface receptors; by contrast, LynA expression is maintained but not required when strong or high-valency ligands induce large-scale receptor clustering.
And in my own experience using a Nokia 920, I found that the social aspects didn't really draw me in or make me feel any more socially engaged – surfacing social updates just reminded me how largely disconnected I actually am from the majority of people in my Facebook stream, in fact.
Therefore, many workers in the field engage in surface bioconjugation of NPs, usually with the goals of making nanomaterials that (i) are biocompatible and (ii) would bind to a particular biological target in or on a living cell.
When binding to the cell, the virus engaged cell-surface heparan sulfate (HS), a relatively conserved feature of the herpesvirus entry pathway [37].
a, The engaged state PTEX150 EXP2 heptamer, displayed in surface representation and coloured by electrostatic potential.
Killer whales are frequently active at the surface, engaging in acrobatic behaviors such as breaching, spyhopping, and tail-slapping.
The gecko can also choose to keep the tips of its toes curled up as it runs, keeping the setae from engaging with the surface it's running on, but that reduces the amount of foot it's able to use while running, which also affects its speed.
