Experimental study of flow boiling under subatmospheric pressures in a vertical square channel
… Heat Flux (CHF) in subcooled boiling flows under subatmospheric pressure. Forced convection boiling is a widely used and effective means of heat transfer. An understanding of the mechanisms and limitations involved in forced convection boiling is important for the accurate prediction of the …

INTERACTION OF NEGATIVE PRESSURE WOUND THERAPY AND COMPOSITE BIOMATERIALS FOR SPINAL FUSION
… 6-sulfate (CS) named material (BRM), or subatmospheric pressure, or synergy of both promote osteoblast proliferation and osteogenic differentiation. Results indicated that osteoblast proliferation significantly increased when cultured under subatmospheric pressure. The osteogenic gene …

An investigation to predict the sub-atmospheric pressure on high spillways
… crests of spillways. The investigation of the subatmospheric pressure which is the main cause of cavitation was primary objective of the thesis. Consequently, a functional numerical model for design purposes was developed. Since viscous effects can be negligible, a two-dimensional irrotational …

ABDOMINAL PRESSURE PROFILING IN ADULT HORSES
… (DR). We demonstrated that flank IAP was subatmospheric and significantly lower than ventrum IAP in standing horses (P < 0.001). Ventrum calculated abdominal perfusion pressure (APP) was lower than flank calculated APP (P = 0.029). Administration of intravenous sedation did not affect IAP, …

Continuous High-Pressure Negative Suction Drain: New Powerful Tool for Closed Wound Management: Clinical Experience
… negative pressure. In addition, continuous subatmospheric suction pressure (100 －300 mmHg) was applied. Outcome of the measures was obtained from the incidence of seroma, volume of postoperative drainage, hospitalization period, and incidence of other typical wound complications. Dead space …

Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic
… in the glass phase of these alkali basalts is subatmospheric, while in the vesicles it ranges between 1.2-2.5 RA (RA = atmospheric ratio). ³He/ ⁴He in vesicles (extracted by crushing in vacuo) allows a correction to be made in the dissolved phase He (by fusion of the remaining powder) for the …

Pool boiling - growth of single bubbles at a heated wall
… a drop tower. Experiments were conducted at subatmospheric pressures using controlled nucleation so that the position and the thermal environment of the subsequent bubble growth were predetermined. Results of the experiments show that the temperature distribution has a marked influence on …
