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...

This study investigates the turbulent flows in simplified Dragon style river channels with a constant critical curvature and different single-short-branch characteristics, using an effective numerical method based on real geometry statistics. First, when branch outlet is closed, main channel, strong bed shear stresses are concentrated at inner bend apex downstream; as widens, more flow enters b...

In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

Secondary flow is a prominent feature of channel bends; it alters the streamwise velocity and bed shear stress distributions. Experiments were conducted to investigate complex pattern secondary in narrow sharp open-channel bend underlying mechanism generation multiple circulation cells. Compared with moderate bends, bends are characteristic cells from 90° section. In addition curvature-induced ...

An open capillary channel is a structure that establishes a liquid flow path when the capillary pressure caused by surface tension forces dominates in comparison to the hydrostatic pressure induced by gravitational or residual accelerations. To maintain a steady flow through the channel the capillary pressure of the free surface has to balance the pressure difference between the liquid and the ...

We develop a mathematical model for the cumulative erosion of micro-particle in channel system. At 90∘ bends system, particle may deviate from flow, impact wall, and erode material. highlight case eroded material adhering to particle, growing size, thus demonstrate how damage accumulates exponentially with time. describe quantify statistical nature evolution growth (mass location). perform this...
