The newest and most advanced testing uses a Hemathix SCV-200 automated scanning capillary tube viscometer (formerly known as the Rheolog), which is capable of measuring viscosity over the complete range of physiologic values experienced in a cardiac cycle
(10,000 shear rates) with a single continuous measurement.
A few examples of the diverse topics covered in the volumes include acorn worm, air masses and fronts, animal cancer tests, big bang theory, biophysics, buckwheat, cardiac cycle
, dentrification, dragonflies, geotropism, ice age refuges, irrational number, legumes, nuclear winter, oscillations, photocopying, quantum electrodynamics, restoration ecology, set theory, squirrel fish, tartaric acid, tumbleweed, ultraviolet astronomy, weather forecasting, xylotomy, and zodiacal light.
The system, which is synchronized to the individual patient's cardiac cycle
, inflates the cuffs with air to create external pressure when the heart is resting and deflates the cuffs just before the next heartbeat.
