... and Borg, 1993 ). It is not clear yet why the short warning time produces a more successful conditioned damping of hearing than a long warning time. It may be hypothesized that odontocetes have an intrinsic motivation to keep their hearing sensitivity as high as possible unless certain circumstances...

... frequency regardless of the kinematics of wing motion. We estimated the damping coefficients for the principal rotation axes — roll, pitch, yaw — in the stroke plane frame. FCT-induced passive damping exists about all the rotation axes examined, suggesting that the effects of body rotation cannot be ignored...

...John H. Long, Jr; Magdalena Koob-Emunds; Benjamin Sinwell; Thomas J. Koob SUMMARY To determine the possible locomotor functions of the hagfish notochord, we measured its flexural stiffness EI (N m -2 ) and flexural damping C (kg m 3 s -1 ), under in vitro conditions that mimicked the body curvature...

... also performed dynamic bending tests on intervertebral segments from the lumbo-caudal joint and the joint between caudal vertebrae 7 and 8. Dynamic bending stiffness (N m rad −1 ) increases with increasing bending amplitude and is independent of bending frequency. Damping coefficient (kg m 2 rad −2 s...

...John H. Long, JR ABSTRACT The stiffness and damping moments that are transmitted by intervertebral joints during sinusoidal bending were determined in the blue marlin, Makaira nigricans Lacépède. Using a dynamic bending machine, the angular stiffness (N m rad −1 ) and damping coefficient (kgm 2 rad...
