objective(s):the aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. quasi-emulsion solvent diffusion was used as a crystal modification method. materials and methods: corn starch was dissolved in hydrochloric acid at 80˚c and then ethanol as a non-solvent was added with lowering temperature ...

This experimental study investigated the effect of plastic waste powder on strength and swelling behavior tuff bentonite soils treated by cement since is highly compressible does not absorb much water. aimed to improve used in construction adding various ratios (5, 10, 20, 25%) a low content (2.5%). Atterberg limit, consolidation, loading-unloading tests were performed determine optimal composi...

In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

The effect of liquid compressibility in the two-stage piston hybrid positive-displacement machine with a was considered. Based on volume conservation equation, we developed calculus methodology for during gas compression second stage compressor section. A numerical experiment made it possible to establish that some parameters have greatest relative decrease height and velocity layer. These are ...

The recently developed laser-induced phonon spectroscopy (LIPS) technique is applied to the determination of dynamic mechanical properties of aligned dilauroylphosphatidylcholine (DLPC) multibilayer arrays containing 2 and 20% water by weight. Sample excitation by two crossed 100-ps laser pulses generates a longitudinal ultrasonic wave whose wavelength depends on the crossing angle. In these ex...

The elastic deformation of a soft solid induced by capillary forces crucially relies on the excess stress inside the solid-liquid interface. While for a liquid-liquid interface this "surface stress" is strictly identical to the "surface free energy," the thermodynamic Shuttleworth equation implies that this is no longer the case when one of the phases is elastic. Here we develop a microscopic m...
