This work discusses the results of a study influence rates change confining pressure on result drained compressibility tests intended to determine modulus rock skeleton Ks. A series cyclical was performed samples sandstone soaked in kerosene, for various compression and decompression liquid filling cell pore volume sample. The studies showed that deformability tested sample directly proportiona...

Weakly nonlinear focusing of quasi-planar ultrasound in a liquid nonuniformly containing many spherical microbubbles is theoretically investigated with special focus on thermal conduction at the bubble-liquid interface toward medical applications such as tumor coagulation by HIFU. Based previously derived Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation our group (Kanagawa, J. Acoust. Soc. Am., 1...

A numerical scheme of study is developed to model compressible two-fluid flows simulating liquid sloshing in a partially filled tank. For a two-fluid system separated by an interface as in the case of sloshing, not only a Mach-uniform scheme is required but also an effective way to eliminate unphysical numerical oscillations near the interface. By introducing a preconditioner, the governing equ...

The development of a three parameters Corresponding States (CS) model is here proposed aiming at the prediction of the saturated and compressed liquid density of pure fluids pertaining to the two conformal families of alkanes (A) and hydrofluorocarbons (HFC) which are widely used as refrigerants. Two fluids of the same family are chosen for both their acentric factor value and for the saturated...

Resveratrol (Res) is a common phytoalexin present in a few edible materials, such as grape skin, peanuts, and red wine. Evidence has shown the beneficial effects of Res on human health, which may be attributed to its anti-inflammatory activity. However, the poor aqueous solubility of Res limits its therapeutic effectiveness. Therefore, the use of nanostructured delivery systems for Res, such as...

Structural polyamorphism has been promoted as a means for understanding the anomalous thermodynamics and dynamics of water in the experimentally inaccessible supercooled region. In the metastable liquid region, theory has hypothesized the existence of a liquid-liquid critical point from which a dividing line separates two water species of high and low density. A recent small-angle X-ray scatter...
