The phrase "motor number" is correct and commonly used in written English.
It is typically used to refer to the identification number of a motor or engine. Example: The mechanic asked for the car's motor number in order to order the correct replacement part.
The speedboat's registration and motor numbers had been defaced, but technicians from the police crime-detection laboratory were able to restore the motor number.
We measured sliding velocities of 57 ± 33 nm s−1 (mean ± SD, N = 265 microtubules, Fig. 2b) in the presence of 1 mM ATP, independent of microtubule length and thus motor number (Fig. 2c, Supplementary Figure 2).
Microtubules showed gliding motility with velocities of 269 ± 95 nm s−1 (mean ± SD, N = 879 microtubules, Fig. 1b), independent of microtubule length and thus independent of motor number (Fig. 1c, Supplementary Figure 1a).
Possibly due to the small force magnitudes, we found no significant correlation between stopping force and motor number, the latter of which was simultaneously quantified using total-internal reflection fluorescence microscopy (see Methods).
By comparison, the sliding velocities of aligned and non-aligned microtubules were not significantly different for non-diffusive, microtubule-crosslinking kinesin-5 motors (Supplementary Figure 3) for which it was also recently reported that the stopping forces scale linearly with motor number irrespective of the crosslinking geometry12.
10.7554/eLife.05472.007 Figure 3. Scaffolds show unidirectional movement along actin networks with directional flux controlled by relative motor number.
For quantification of motor neuron number, CC1+ oligodendrocyte number, casp3+ cell number and GFAP or MBP levels, at least three sections/animal, three animals/group were used.
Motor octane number and research octane number of gasoline produced by CAT-new sample have increased 0.1 and 1.0 unit, respectively.
Compared with CAT-old, the motor octane number (MON) and research octane number (RON) of gasoline produced by CAT-new sample can increase 0.1 and 1.0 unit, respectively.
For Cat-3, the yields of iso-paraffins and aromatics were obviously higher which enhanced the octane numbers of FCC gasoline, especially for the motor octane number (MON).
It has a motor octane number of 98 which exceeds that of gasoline (octane number of 80).
