At the other extreme, basin morphometry (geometric aspects of basins and their measurement) can be made to indicate the limiting average area necessary to sustain a given length of channel; in large areas of the midlatitudes, the ratio is close to 2.25 square kilometres of drainage area for a channel 1.6 kilometres in length.
The point is that current approaches focusing on risk do not call into question the visions and imaginaries that sustain a given technology's trajectory [33, 24].
In the twentieth century, scientists have examined running speed over various distances, analyzing world records and studying the ability of an athlete to sustain a given speed.
The "speculative" capacity of an image or word concerns its ability to sound out or insinuate the unstated nexus of meanings which sustain a given expression but which are not directly given in it.
The mortality risk ratio (MRR), a measure of the proportion of people who died that sustained a given injury, is reported to be among the most powerful discriminators of mortality following trauma.
However, there is a lack of fundamental understanding on the interactions between the incentive mechanisms and the underlying protocols (e.g., shortest-path routing, ETX routing or back-pressure scheduling), and whether integration of these protocols will lead to a robust network, i.e., networks can sustain a given traffic workload.
Disadvantaged birds had to sacrifice more angle to sustain a given take-off speed.
In addition, mechanical efficiency is related to how muscles produce the mechanical work needed to sustain a given speed [ 10, 11].
These evidences suggested that the central command can operate independent of actual motor activation, and that afferent input from the exercising skeletal muscle determines the magnitude of cardiovascular response required to sustain a given metabolic demand when effort sense is reduced below a critical level.
Skeletal muscle function is described by muscle strength (the ability to generate force production), muscle endurance (the ability to sustain a given contraction over time), and muscle fatigue (a physiological sense defined as the failure of force generation resulting from activity under load which is reversible by rest).
