The Hg partial pressure
given in this work is around 6.4 bar whereas [Dakin 1989] obtained a Hg partial pressure
of about 4.7 bar which is within the experimental uncertainty.
(10), (11) In fact, [a.sub.M] is far less than unity; thus, the real equilibrium partial pressure
P[O.sub.2] equilibrium is much higher than the pressure over pure M and [M.sub.x] [O.sub.y]
The equilibrium between Hb, Hb[O.sub.2], and HbC[O.sub.2] is governed by the partial pressures
of [O.sub.2] and C[O.sub.2] in the system and is assumed to occur instantaneously since the gas exchange through the erythrocyte membrane is relatively fast due to its high surface area (Constantine et al., 1965) and, therefore, the Hb[O.sub.2]-Hb-HbC[O.sub.2] equilibrium reflects the chemical composition of the blood culture vial.
Three oxygen partial pressures
(0.5, 1, and 1.5 Mpa) were tested at all temperatures.
Taking into account carried out similar investigations with application of melting in suspension state, which showed impossibility of achieving equilibrium in Zr- N system, such temperature, partial pressure
of nitrogen, and duration of molten zirconium soaking in nitrogen were selected that formation of nitrides on the metal surface to be excluded.
where p is gas partial pressure
[N/[m.sup.2]], t is time [s], [D.sub.eff] is the effective diffusion coefficient [[m.sup.2]/s], and z is the spatial coordinate [m].
As stated previously, newer Pb[O.sub.2] probes have the ability to measure not only the partial pressure
of oxygen but also Pb[CO.sub.2], pH, and temperature.
The concentration of a given gas species in the liquid phase is proportional to its partial pressure
or molar concentration in the gas phase (Henry's law).
In addition, pulmonary X-ray, arterial oxygen partial pressure
(PaO2), oxyhemoglobin saturation, carbon dioxide partial pressure
(PaCO2), oxygenation index (OI), and ratio of arterial/pulmonary oxygen partial pressures
(a/AO2) were also compared.
The performance of the nickel-based and the palladium-based FBMR are analyzed by investigating the impact of major operating parameters (reactor pressure, temperature, permeate side hydrogen partial pressure
and steam feed rate) on methane conversion and hydrogen yield.
In the first case, time-dependent measurement of precursor density (partial pressure
) can provide insight into precursor delivery stability and process parameters affecting the stability.
