The effect of granular pressure on the fluctuation volume fraction is investigated experimentally in a gas–solid flow system. Granular compressibility, defined by response fractions pressure, also measured. It found that there exists critical beyond which transition from coexistence liquid-like phase and gas-like to homogenous fluids takes place. heterogenous characterized an abrupt change comp...

Compressive properties of electrospun fiber mats are reported for the first time. Mats of bisphenol-A polysulfone (PSU) and of poly(trimethyl hexamethylene terephthalamide) (PA 6(3)T) were electrospun and annealed at a range of temperatures spanning the glass transition temperature of each polymer. The data for applied stress versus mat solidity were found to be well-described by a power law of...

[1] Seismically, the African superplume is known to have a sharp lateral transition in VS and an interface between seismic anomalies with high relief. Such a structure is usually unstable in conventional thermo-chemical convection models. Using a compressible thermo-chemical convection model in which each material has a distinct equation of state, we find an expanded regime of metastable superp...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...
