dissolved nitrogen predispersed solvent extraction (dnpdse) is a new method devised for improving the performance of equipment utilized in the solvent extraction (sx) method, especially for dilute solutions. in this method, for mixing the two phases, bubble dispersion of the organic phase (colloidal gas aphrons [cgas]) is used instead of its drop dispersion in the aqueous phase. through increas...

In this paper, we extend the sliding mode idea to a class of unmatched uncertain variable structure systems. This method is achieved with introducing a new terminal sliding variable and the finite time stability of proposed method is proved using a new particular finite time condition in both reaching and sliding phases. In reaching phase new sliding mode controller is derived to guarantee the ...

this study investigates the contributions of atlantic ocean to june-august rainfall over uganda and western kenya (ku). the study has utilized the datasets including precipitation from the global precipitation climatology centre, north atlantic oscillation index (naoi), south atlantic ocean dipole index (saodi), era-interim reanalysis, and the atlantic ocean sea surface temperature (sst). singu...

By watching each other's lower oscillating leg, 2 seated Ss kept a common tempo and a particular phase relation of either 0 degrees (symmetric mode) or 180 degrees (alternate mode). This study investigated the differential stability of the 2 phase modes. In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the ...

We demonstrate that E×B shear, V_{E×B}^{'}, governs the dynamics of the cross phase of the peeling-ballooning-(PB-)mode-driven heat flux, and so determines the evolution from the edge-localized (ELMy) H mode to the quiescent (Q) H mode. A physics-based scaling of the critical E×B shearing rate (V_{E×B,cr}^{'}) for accessing the QH mode is predicted. The ELMy H mode to the QH-mode evolution is s...

Optical transmission spectrum measurements in an electric field are used to study the short-range structure of the blue phase III (BPIII). The data are compared with the theoretical models for BPIII. Our results can be explained by the models in which BPIII has the simple-cubic local structure or cubic bond orientational order.

The gradual transformation of a guided TM00 mode into an ‘‘intermediate’’ double mode by a splitting junction has been investigated with a phase-sensitive photon scanning tunneling microscope. Field profiles and wave vectors of the modes have been directly determined from the phase information. Via a Fourier analysis of the measured phase and amplitude maps the decay of the TM00 mode and buildu...
