This method of measuring stress is currently the most popular method in the clinic.
Uses the changes in resonant frequency in a sensing mechanism to measure stress, or changes in gas density, caused by applied pressure.
Other psychologists, however, proposed measuring stress indirectly, through self-tests.
Instead it measures stress, because rail neutral temperature is merely the ambient air temperature where the fixed length of rail has no compressive or tensile stress.
It was this research, and the need to measure stress caused by earthquakes that eventually led to Ruge's invention of the strain gauge.
The PSS was published in 1983, and has become one of the most widely used psychological instruments for measuring nonspecific perceived stress.
The beamline uses neutron diffraction to determine the spacing between layers of atoms in order to measure elastic strain, and thus residual stress deep within crystalline materials.
Koren's research in this area has also led to a new biological marker that can be used to help prevent heart attacks, measuring chronic stress over time.
Dr. Southern, a biophysical chemist, arrived at the fisheries center in 1998 under a grant to develop a technique for measuring stress in skin samples.
