Raman spectra of Mg2GeO4-olivine were obtained from ambient pressure up to 34 GPa at ambient temperature. Under quasi-hydrostatic pressure conditions, the following modifications in the Raman spectra occur as pressure increases: 1) near 11 GPa, two sharp e ...
A nonlinear method has been developed to separate arterial pressure and flow waves into their forward and backward running components. It takes into account nonlinearities arising from the area-pressure relationship as well as convective acceleration. The ...
The sepn. was demonstrated by studying the IR multiphoton dissocn. of CF2DCl [1495-14-3] and CF2HCl/CF2DCl mixts. It is shown how the parameters which control the IR photochem. of CF2DCl such as the temp. and the pressure, as well as the wavelength, the en ...
An experimental study of flow in a Francis hydraulic turbine, especially designed for the GAMM Workshop, has been carried out. In order to provide a data base for the validation and comparison of computational fluid dynamics codes, a Francis turbine mode! ...
The frequency shifts from gas-phase values of the vibrational and rotational states of H2, D2, and HD mols. matrix isolated in solid Ar, Kr, and Xe were calcd. at zero temp. and at pressures 0 ? P ? 570 kbar. Also calcd. were the impurity local mode freque ...
We present a new experimental set-up for studying minerals by Raman spectroscopy in-situ at simultaneously high pressures (up to 35 GPa) and high temperatures (up to 2000 K). High pressures are generated with a diamond anvil cell and local sample heating i ...
The non-linear elastic response of arteries implies that their mechanical properties depend strongly on blood pressure. Thus, dynamic measurements of both the diameter and pressure curves over the whole cardiac cycle are necessary to characterise properly ...
The use of microbalances to study gas-solid reactions at high temps. and normal pressure is often limited by fluctuations due to thermal convection in the reaction zone. The fluctuations depend on the pressure, the type of gas, the temp., and the geometry ...
The laser flash photolysis of I was studied over a wide pressure range in several bath gases. At low pressures the obsd. quantum yield for photolysis at 6943 .ANG. is independent of the gas d., whereas at higher pressures the quantum yield decreases with i ...
The effect of sound-induced reaction rate changes on mass transfer between the reactor wall and the gas was studied in the frequency range 275-1325 Hz and pressures ?165.7 decibel under laminar-flow and steady-state conditions. The catalytic hydrogenation ...
