This often results in closed circulations at low levels over the eastern Pacific Ocean, many of which develop into tropical cyclones.
This hybrid cooler normally operates in the vapor compression mode at high ambient temperatures, but works in the natural circulation mode at low ambient temperatures by the thermosiphon principle.
IgM is also absorbed into circulation, though at low concentrations (<1%) [17].
Early EPC characterised by the expression of CD34, CD133 and the VEGFR-2 (Flk-1, KDR) are present in the circulation at very low numbers and cannot be quantified by flow cytometry without previous enrichment procedure.
Two-phase hydrodynamic regimes establishing in a lab-scale internal circulation airlift operated at low superficial gas velocity have been investigated.
In general, the RELAP5 code can consistently simulate the two startup transients and predict two flow instabilities, i.e., flashing instability and density wave oscillations, occurred in the natural circulation test facility at low pressures.
Despite the reduction in uterine blood flow (Table 2), maternal glucose delivery to the uteroplacental circulation was similar at low versus high altitude (Fig. 1C).
Oscillations in the gas holdup and liquid circulation velocity were found at low liquid levels in an airlift reactor with a designed gas liquid separator.
We hypothesized that this early response, obtained from immunogen-stimulated lymphocytes at the beginning of antigen circulation and thus present at low concentrations, corresponded to the existence of high-affinity surface immunoglobulins that would later be secreted by these lymphocytes.
