Though these terms themselves may be somewhat ambiguous, they are usually used in a context in which their meaning is clear. For example, when referring to a drive shaft it is clear what is meant by axial or radial directions. Or, in a free body diagram, one may similarly infer a sense of orientation by the forces or other vectors represented.
This movement has also been described as negative training. This "negative" movement is necessary to reverse the muscle from its initial trajectory. [1]When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy.
Human positions refer to the different physical configurations that the human body can take. There are several synonyms that refer to human positioning, often used interchangeably, but having specific nuances of meaning. [1] Position is a general term for a configuration of the human body. Posture means an intentionally or habitually assumed ...
The α- and β-anomers of D-glucopyranose.. In organic chemistry, the anomeric effect or Edward-Lemieux effect (after J. T. Edward and Raymond Lemieux) is a stereoelectronic effect that describes the tendency of heteroatomic substituents adjacent to a heteroatom within a cyclohexane ring to prefer the axial orientation instead of the less-hindered equatorial orientation that would be expected ...
Substituents on a cyclohexane ring prefer to reside in the equatorial position to the axial. The difference in Gibbs free energy (ΔG) between the higher energy conformation (axial substitution) and the lower energy conformation (equatorial substitution) is the A-value for that particular substituent.
A new study found that Americans 40 and older could live over five years longer if they exercised as much as the top 25% of the population. Here's what to know.
