steady-state velocity

stead·y-state ve·loc·i·ty

the velocity of an enzyme-catalyzed reaction in which, over the time course of the study, the concentration of any enzyme species is constant (that is, for an enzyme-substrate binary complex, ES, d[ES]/dt ≈ 0; for this to hold true, the total enzyme concentration must be much less than the initial substrate concentration.
Synonym(s): steady-state rate

As a corollary, it can be concluded that the slope observed at the reactivating segment does not correspond to an authentic steady-state velocity. This point must be stressed, because, in some works dealing with the atypical kinetic behavior of TGR [11, 16, 37], the maximal slope in a full time progress curve of GSSG reductase activity has been mistakenly noted as a true steady-state velocity.
Based on equations (9~11), the relationship between the steady-state velocity and the friction force is
The relationship between critical velocity, maximal lactate steady-state velocity and lactate turnpoint velocity in runners.
The reaction progress curves for the unpreincubated system were concave downward (Figure 4(a)), indicating that the velocity of urea hydrolysis decreased from an initial velocity ([v.sub.o]) to a much slower steady-state velocity ([v.sub.s]) according to the apparent first-order velocity constant [k.sub.app].

The steady-state velocity profiles for different magnetic parameter are shown in Fig.
It is essential that the designer be aware that each fluid motor exhibits its own particular set of characteristics when it must first start rotating a load from zero to some steady-state velocity. Internal losses in a fluid motor consist of three components:
Figure 4 shows the effect that changing the cooling conditions (air temperature and air velocity) has on the steady-state velocity profiles for Nylon.
Steady-state velocity measurements have an accuracy of 0.1 knot.
The present model simulates hot electron transport properties by using nonlinear steady-state velocity and diffusivity curves in the current continuity equation.
All primers producing detonation velocity above the main charge's steady-state velocity at which the explosive would detonate for a given diameter.
When we earlier discussed the choice of velocity profile, Method 1 was presented as a case of steady-state velocity, which is true during time interval [t.sub.3] - [t.sub.1].
