In this paper, a new scheme is proposed to remove the spiral wave in a two-dimensional Fithhugh–Nagumo type equation by introducing a class of vortex electric field into the media. A long electric solenoid with large pipe diameter is used to generate a spatial magnetic field and the intensity of magnetic field B is controllable. A vortex electric field could be induced by changing the external ...

Membrane filtration is employed for water treatment and wastewater reclamation purposes, but membranes alone are unable to remove pollutant molecules and certain pathogens. Photocatalytically active N-doped TiO2 coatings have been deposited by solegel onto 200 nm pore size alumina membranes for water treatment applications using two different methods, via pipette droplets or spiral bar applicat...

To reduce the computation load for electromagnetic field analyses of magnets wound with spiral coated-conductor cables, we developed a simplified analysis method. In method, analyze single cable carrying transport current under external magnetic field, which is generated by in adjacent cables while ignoring influence shielding currents them. We conducted numerical and without model directly com...

Disruption of the plasma membrane evokes an exocytotic response that is required for rapid membrane resealing. We show here in Swiss 3T3 fibroblasts that a second disruption at the same site reseals more rapidly than the initial wound. This facilitated response of resealing was inhibited by both low external Ca2+ concentration and specific protein kinase C (PKC) inhibitors, bisindolylmaleimide ...

A mathematical model is derived to simulate the performance of spiral wound membrane modules for the pervaporative separation of binary liquid mixtures. Permeation through the polymer membrane is described by a detailed solution–diffusion model. Flory–Huggins theory is used to predict solubility of the penetrants, while the composition and temperature dependence of the diffusion coefficients ar...

The ideal dressing material is bio-inert and keeps the wound site moist. It is equally important that no regenerative tissue is peeled off on the removal of the dressing. 2-Methacryloyloxyethyl phosphorylcholine (MPC) has a phospholipid polar group that mimics a biomembrane. We prepared poly [MPC-co-n-dodecyl methacrylate (DMA)] (PMD), using conventional radical polymerization with 2,2'-azobisi...

Abstract To enhance the heat transfer efficiency of spiral wound exchanger, a grooved exchanger (GSWHE) was proposed. A test platform accomplished to experimentally investigate performance with comparison (SWHE). The uncertainty analysis experiment conducted, maximum relative error being not more than ±5%. comprehensive coefficient GSWHE is higher that SWHE when cooling water flow rate low. det...
