We have applied sweeping micellar electrokinetic chromatography (sweeping-MEKC) to the simultaneous determination of Delta(9)-tetrahydrocannabinol (THC) and its major metabolites, 11-hydroxy-Delta(9)-tetrahydrocannabinol (THC-OH) and 11-nor-9-carboxy-Delta(9)-tetrahydrocannabinol (THC-COOH). We monitored the effects of several of the sweeping-MEKC parameters, including the proportion of organic...

This article reviews the recent theories and models of space-time energy spectra in turbulent shear flows. The review is based on picture passage proposed by Taylor's frozen-flow hypothesis Kraichnan-Tennekes random sweeping hypothesis: convection small-scale eddies large-scale with a certain distortion, which determines peaks bandwidths spectra. data-refined stochastic data-based reconstructio...

We experimentally demonstrate tunable radiation from a periodic array of plasmonic nanoscatterers, tailored to convert surface plasmon polaritons into directive leaky modes. Extending our previous studies on efficient directional beaming based on leaky-wave radiation from periodic gratings driven by a subwavelength slit, we experimentally show dynamic beam sweeping by tuning the directional lea...

We present a fast sweeping method for class of Hamilton-Jacobi equations that arise from time-independent problems in optimal control theory. The basic two dimensions uses four point stencil and is extremely simple to implement. test our against Eikonal different norms, then suggest general rotating the grid using additional approximations derivatives directions order more accurately capture ch...

A dynamic simulation was launched to research the influence of high-pressure turbine (HPT) rotor wake passing frequency on flow mechanism in an integrated aggressive interturbine duct (AITD). Sweeping rods were adopted replace HPT rotors decouple its from those other secondary flows. The diameter (d/s, nondimensionalized by pitch (s) struts at midspan) 0.10, and their reduced (f) ranged 0.49 1....
