The normal resting adult human heart rate ranges from 60â100 bpm. Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest. During sleep a slow heartbeat with rates around 40â50 BPM is common and is considered normal.eart rate, or heart pulse, is the speed of the heartbeat measured by the number of contractions of the heart per unit of time â typically beats per minute (bpm). The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
In materials science, deformation refers to any changes in the shape or size of an object due to-. 1  an applied force (the deformation energy in this case is transferred through work) or. 2  a change in temperature (the deformation energy in this case is transferred through heat).
Tectonics. (or geotectonics), a branch of geology that studies the structure of the earthâs crust and its changes under the influence of mechanical tectonic movements and deformations associated with the development of the earth as a whole (see and).or geotectonics), a branch of geology that studies the structure of the earthâs crust and its changes under the influence of mechanical tectonic movements and deformations associated with the development of the earth as a whole (see and).
