The influence of localized water currents on the nonlinear dynamics and stability of large amplitude, statistically distributed gravity waves is investigated theoretically and numerically by means of an evolution equation for a Wigner function governing the spectrum of waves. It is shown that water waves propagating in the opposite direction of a localized current channel can be trapped in the ...

The objectives of our studies in FY09 are to collect observations of currents, waves, and bathymetry on tidal flats, and to develop, test, and improve models for tidal-flat processes and for mud-induced dissipation of waves in shallow water. Specific goals relating to tidal flats are to: Investigate the relative importance to the circulation of riverine and tidal flows, and Estimate the bottom ...

Abstract. Iontophoresis currents are used in the transcutaneous delivery of vasoactive substances for noninvasive assessment of skin vascular properties. The blood flow rate can be recorded by laser Doppler flowmetry (LDF), its average value and the amplitudes of its oscillatory components being used to evaluate the effect of the drugs. Because non-drug-specific, current-induced, vasodilation c...

Anguilla japonica and Anguilla marmorata share overlapping spawning sites, similar drifting routes, and comparable larval durations. However, they exhibit allopatric geographical distributions in East Asia. To clarify this ecological discrepancy, glass eels from estuaries in Taiwan, the Philippines, Indonesia, and China were collected monthly, and the survival rate of A. marmorata under varying...

The goal of this study was to determine the effects of the L-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fKv1.4ΔN), an N-terminal-deleted mutant of the ferret Kv1.4 potassium channel. Measurements were made using a two electrode voltage clamp technique with channels expressed stably in Xenopus oocytes. The fKv1.4ΔN currents displayed...

The electrical conductivity of several rock meal based fertilizers with expressed ISR activity, measured as voltage dropping when their distilled water solution was affected low – electric currents 5 volts (DC and AC) examined. For comparison, hard soft tap (with 196 65 ppm CaCO3 hardness), 1% solutions NaCL CuSO4.5H2O 0.1% organosilicone surfactant were also tested in the conducted trials. res...
