Flow reattachment lengths (l(r)) are measured downstream of an abrupt axisymmetric 75% stenosis, located inside a cylindrical channel, for steady flow using ultra-fast magnetic resonance imaging (MRI). The MRI results are compared with those from oth

The rotating ultra-fast imaging sequence (RUFIS) is used to image spins flowing through the curved portion of a 180 degrees U-tube with a circular cross section and a ratio of inner diameter to curvature diameter of 0.41. A velocity-encoding preparat

The most often used nuclear magnetic resonance imaging technique at the present time is the spin warp (SW) technique and various derivatives of it. Of the many techniques that have been developed until now, it has proven to be the roost versatile and

The fluoride ion motion in β‐PbF2 doped with NaF was studied by measurement of the 19F transverse relaxation time (T2), spin lattice relaxation time (T1), and the spin lattice relaxation time in the rotating frame (T1r). Measurements over the temp

Rotating-frame relaxation experiments have been carried out on 19F-labeled dimyristoylphosphatidylcholine model membranes. The lipids are labeled with a single CF2 group in the 4-, 8-, or 12-position of the 2-acyl chain. Both oriented lipid bilayers

A sample probe for pulsed nuclear magnetic resonance that replaces the normal resonant circuit by a lumped parameter delay line is described. Theoretical analysis shows that the delay line probe has a signal‐to‐noise ratio and conversion efficien

The results of measurements of the proton spin–lattice relaxation time T1 in ice are reported. The ice samples were single crystals grown by zone refining at atmospheric pressure. The measured activation energy for the T1 process is 14.1 ± 0.1 kca
