Greene and Institute for Basic Standards (U.S.). Electromagnetics Division. A method is described for accurately determining the radio frequency (rf) power being absorbed by a biological specimen during nonionizing radiation exposure testing using the National Bureau of.

The measurement of biological compounds in body fluids and tissues is a critical component of clinical research and represents an objective endpoint for many trials, especially those involving therapeutic : Mark D. Kellogg. Acoustic absorption has been measured in a series of biological tissue specimens—porcine muscle, renal and fat tissues—by the standard insert-substitution method, as well as by ultrasonic phase by: 4.

The mass and change of mass of biological specimens resulting from variations in environment and nourishment have long been used not only as indications of the physiological well-being of the specimen, but also as a necessary measurement in experiments designed to explain normal and disturbed physiological mechanisms.

In others, disease rates are rising as affluence and industrialization. Calorimetry is performed with a calorimeter. Isothermal microcalorimetry (IMC) is a laboratory method for real-time, continuous measurement of the heat flow rate (μJ/sec = μW) and cumulative amount of heat (J) consumed or produced at essentially constant temperature by Classification: Thermal analysis.

For each material, varying thickness specimens were fabricated in order to measure attenuation as a function of penetration distance. Measurements of power loss were taken at 2 MHz intervals from to 2 GHz and from 3 to 8 GHz.
