Abstract

Key comparisons (KCs) are required to ensure equivalence between laboratories and to substantiate Calibration and Measurement Capabilities (CMCs). The previous radiation thermometry KC (CCT-K5) finished in 1999 and used tungsten ribbon lamps as the transfer instruments. These were not ideal: - their radiance temperature is strongly wavelength dependent, so corrections - had to be applied to the results to account for the different measurement wavelengths - the target size of lamps is small (typically 1.5 mm width) compared to the field-of-view of many radiation thermometers - the inherent uncertainties associated with lamps tend to be large - the upper temperature of the comparison was 1700 °C whereas many laboratories can now achieve up to 2500 °C or even 3000 °C., XIII International Symposium on Temperature and Thermal Measurements in Industry and Science, TEMPMEKO 2016, June 26 - July 1, 2016, Zakopane, Poland

30. Investigation of mass-transfer in occluded rat artery In Vivo.

Author

Matveyev, M., Borovikov, D., Golubykh, V., and Domogatsky, S.

Abstract

The release of radiolabeled immunoglobulins from distal end of blocked rat carotid artery was studied in vivo. The elimination half-time was 8–9 min for a 4–5-cm long segment of blocked artery and 16–24 min for a 7–8-cm long segment. Surprisingly high rate of convection in completely blocked arteries under conditions of pulsatile pressure has been demonstrated. [ABSTRACT FROM AUTHOR]
