introduction numerous studies have demonstrated the presence of potassium selective channels in membranes internal organelles. these channels are essential to a large variety of cellular processes including intracellular 2+ a signaling, protein recycling, charge neutralization and cell protection. in contrast to the sarcoplasmic reticulum + here potassium channels have been clearly identified, ...

• Porous block influences the flow development in a serpentine cooling passage. Quantative comparison of between smooth and porous blocks channel. Rotation effect on overall character for fluid through along duct. The pressure coefficient is found to decrease linearly channel, due high blockage by blocks. This study investigates how inclusion passage, which consists two straight square-sectione...

This paper is motivated by the need to develop low cost, wireless velocity sensors for hydraulic research and application in streams. A velocity bend sensor (VBS) is a flexible plastic polyimide substrate sheet with an electronic resistor connected to a voltage divider. Drag of a moving fluid bends the sensor, changes the electronic resistance, and produces a voltage drop that can be related to...

In this paper, we derive a new geometrical blind bend scattering model for vehicle-toinfrastructure (V2I) communications. The proposed model takes into account single-bounce and doublebounce scattering stemming from fixed scatterers located on both sides of a curved street. Starting from the geometrical blind bend model, the exact expression of the angle of departure (AOD) is derived. Based on ...

The flow of a glacier along a channel of constant longitudinal curvature is analyzed using analytical and finite-element methods. Channels of various cross­ sectional shape are investigated, ranging from a simple rectangular form with zero shear traction along the bed to realistic profiles taken from Blue Glacier, Washington. Terms in the equilibrium and rate-of deformation equations which are ...

determination of the deformation length is one of the first steps in roll forming design. roll forming industries are very interested in explicit simple relationsfor prediction the deformation length without using trail-and-error methods at workshop or time consuming finite element simulations. in this paper, elastic properties and work-hardening behaviour of the strip are considered in additio...

this paper presents the results of a numerical study on the heat transfer performance and the removal process of fluid particles under the influence of magnetohydrodynamic mixed convection in a horizontal channel with an open cavity. the bottom wall of the cavity is heated at a constant temperature (th) while the top wall of the channel is maintained at a relatively low temperature (tc). air wi...
