The phase transitions wfuch occur in a diace@fene polymer crystal (PIS) at 195 K and a d.iacetyIene mouomex cxy~ti (DCH) at 142 K have been stodied as a function of pressure. For the second-order phase transit~oa in PTS tie pzesswe dependence of the transition tempera-e was found to be less than 0.0

## Abstract The refractive index n(Ο, __T, p__) of molecular chlorine, Cl~2~, was measured in the ranges of temperature __T__ between 290 and 1100 K and pressure __p__ between 10^4^ and 2 Γ 10^5^ Pa and at three wavelengths Ξ» = 2ΞΌc~o~/Ο between 632.990 and 543.516 nm. From these measurements the fr
## Abstract In this work the effects of noise, resolution, and velocity (flow) on the measurement of intravascular pressure from phaseβcontrast (PC) MRI are discussed. To elucidate these effects, we employed an axisymmetric geometry that enabled us to calculate pressures in <2 min on a Sun Ultra SP
A very weak interdimer exchange coupling was determined as a function df hydrostatic pressure up to 500 MPa from the EPR line-merging effect. The exchange integral is IJI ~0.0032 cm-t under normal conditions and increases linearly with slope d 1 JI ldp = 6 x IO -6 cm -'/MPa. Comparison between the p
