Whereas four of the five brain tissues studied were saturated within about six minutes, the cerebral parietal cortex may not be completely saturated even after a twenty minute period of inhalation of xenon at a constant tension. The xenon concentration of adrenal gland tissue rises rapidly and ...

of the time courses of their approach to saturation, the curves presented in the chapter provide a reference against which to compare the non-saturation exposures in which the inert gas uptake by a tissue is a function of both the exposure time and the tissue-inert gas exchange time constant...
We present a new method for the continuous flow production of concentrated hyperpolarized xenon-129 (HP 129Xe) gas from a dilute xenon (Xe) gas mixture with high nuclear spin polarization. A low vapor pressure (i.e., high boiling-point) gas was introduce
The problem is formulated in terms of response theory, which relates the dielectric constant to an integral of a correlation function, and the lowest-order contribution is explicitly calculated using the same empirical expression for the dipole moment as was used by Levine and Birnbaum....
for a few hours while maintaining a constant flow of nitrogen or argon through the oven. FIG. 6 shows a detailed illustration depicting the complete fabrication process flow. It is important to avoid leaks. A mismatch in the top and bottom halves may provide a leaky path through which ...
Several methods to determine the WVTR can be considered equal pressure methods as they use a constant flow on the downstream side to take the permeated water vapour molecules towards the detection system. There are several detectors, which can serve this purpose. However, similar as to the coulom...
