## Abstract A technique is presented for rapidly and noninvasively determining aortic distensibility, by NMR measurement of wave velocity in the aorta. A twoβdimensional NMR selectiveβexcitation pulse is used to repeatedly excite a cylinder of magnetization in the aorta, with magnetization read out

β¦ Synopsis
An oscillating mirror scanned a He-Ne laser beam along the length of a thin rod while the rod was ablated by an argon laser beam. The shadow of the scanning beam on an image plane provides a picture of the instantaneous ablation velocity of the rod. This configuration provides a unique method for investigating onedimensional ablation.

In studies on river channel flow turbulence, it is often the case that the measured mean vertical velocity is different from zero, indicating that the frame of reference of the current meter is not parallel to the flow streamline. This situation affects the estimate of Reynolds shear stress in the s
## Abstract A oneβdimensional pulse scheme employing pulsed field gradients for detecting only quaternary carbons is reported. This new scheme, referred to as PFGβQCD (pulsed field gradient quaternary carbon detection), suppresses primary, secondary and tertiary (CH~3~, CH~2~ and CH) carbons very e
The method for computing normal burning velocity, called S u, [rom observed data in constant-volume bomb measurements is developed from first principles. The theory accounts approximately for effects due to the finite velocity of sound, and shows how radius~time measurements may he used to determine
One-dimensional continuous-wave laser tissue ablation models predict that the steady-state ablation velocity is independent of the optical absorption of the tissue and proportional to laser power density. This theoretical result was tested in an experimental model that approximates the one-dimension
