Long-term whole-body vibrations can cause degeneration of the lumbar spine. Therefore existing degeneration has to be assessed as well as industrial working places to prevent further damage. Hence, the mechanical stress in the lumbar spine鈥攅specially in the three lower vertebrae鈥攈as to be ...
: the total amount of kinetic and potential energy possessed by the molecules of a body and their ultimate parts owing to their relative positions and their motions inside the body and excluding the energy due to the passage of waves through the body and to vibrations of the body ...

Explain the functioning of kidneys. What is the diaphragm? What characterizes static stretching? What is the difference between vibrations and frequencies? What is the purpose of the diaphragm? What is the definition of sensory detail? Describe how momentary dipoles cause induced dipoles. How does ...

It also processes other tactile sensory information from the skin, including vibrations, light touches, and pressure signals. The primary motor cortex of the brain stores its axons in the posterior limb of the internal capsule. Axons are the part of a nerve cell that conducts electrical ...
Previous research has shown that the stress level induced by ultrasonic vibrations in rocks is lower than the crack initiation stress [34]. The induced damage causing strength degradation includes two parts: the thermal damage attributed to friction between the vibration head and sample surface [31,...
Any resonant vibrations which might occur tend to have a desirably low "Q". While the invention has been described and illustrated in detail, it is to be clearly understood that this is intended by way of illustration and example only and is not to be taken by way of limitation, the ...
