A rolling-sphere viscometer (RSV) was constructed and evaluated for monitoring apparent viscosit~'es of fermentation broths in sha'ke flasks or test tubes. The apparatus was calibrated by measuring translational velocities of magnetic stainless ste.el spheres (0.16-0.95 em diameter) rolling in N~wto­ nian viscosity standards (50-12.500 mPa's) on surfaces inclined 20° to 70°. The method was appl...

l. Hypothermic lizards (Egernia ctmninghami) showed significant reductions in plasma volume, haematocrit and haemoglobin concentration. The changes in the distribution of red cells were acutely reversible when body temperature was increased. 2. Consequently, there were no significant alterations in blood viscosity (when measured in z&o in a capillary viscometer) between body temperatures of 32°...

Title: Whole blood viscosity in individuals with insulin-dependent diabetes mellitus: Exploring the role of the porous bed viscometer Objective: The study was performed to evaluate the capacity of a porous bed viscometer (PBV) to demonstrate differences in blood viscosity in patients with diabetes mellitus and to investigate the • role that various cellular and plasma components play in determi...

Abstract Previous experimental viscosity data for gaseous methane, published by Schley et al. (Int J Thermophys 25:1623, 2004) and originally obtained using a vibrating-wire viscometer in the temperature range between 260 K 360 K, were re-evaluated after an improved re-calibration. For this purpose, new reference value argon at 298.15 zero density, proposed Vogel (Mol Phys 108:3335, 2010) furth...
