this research is on the improvement of the procedure to determination of trace levels of antidepressant drug; fluoxetine in wastewaters. in this research a silica based sol-gel was applied for the extraction of fluoxetine from water samples. this two-phase technique is consisting of aqueous samples of fluoxetine (donor phase) and silica based nanocomposite prepared by sol-gel technique (accepto...

The effective shear and bulk viscosity, as well as dynamic viscosity, describe the rheological properties of the ceramic body during the liquid phase sintering process. The rheological parameters depend on the physical and thermo-mechanical characteristics of the material such as relative density, temperature, grain size, diffusion coefficient, and activation energy. Thermal behavior of the cer...

Phase transformation affects multiphase flow in geothermal and gas-condensate reservoirs due to the same substance occurring in different phases. These effects change the phase behavior and the flow characteristics. The goals of this research were to compare the flow behavior and relative permeabilities difference between two-phase flow with and without phase transformation effects in smooth-wa...

The purpose of this investigation was to determine if phase plot normalization and phase angle definitions would have an affect on continuous relative phase calculations. A subject ran on a treadmill while sagittal plane kinematic data were collected with a high-speed (180 Hz) camera. Segmental angular displacements and velocities were used to create phase plots, and examine the coordination be...

We investigate the effect of different saturation histories relevant to various oil displacement processes (including secondary and tertiary gas injections) on three-phase gas/oil/brine relative permeabilities of water-wet sandstone. It is found that three-phase water (wetting phase) relative permeability is primarily a function of water saturation and shows no dependency upon saturation histor...

Abstract Long-term maintenance missions present a challenge for low-orbit heterogeneous area-to-mass ratio (AMR) microsatellite constellations due to inconsistent fuel consumption and carrying capacity. Based on the idea of cooperative control, fuel-rich satellites is properly increased in this paper assist fuel-starved saving fuel, so as optimize balance each satellite extend controllable life...

We study coherent dynamics of two interacting Bose-Bose droplets by means the extended Gross-Pitaevskii equation. The relative motion couples to phases their components. can be understood in terms evolution zero-energy modes recovering symmetries spontaneously broken mean-field solution. These are translational symmetry and U(1) symmetries, associated with droplets' A phase-dependent interactio...
