چکیده
ETHODS A portion of the left ventricular epicardial surface of angendorff-perfused rabbit hearts was stimulated using uniform lectric fields produced by two parallel line electrodes. The Vms ere recorded from di-4-ANEPPS-stained hearts using a multisite ptical mapping system. The hearts were paced with 20 S1 pulses rom the apex, and shocks (S2: 5, 10, 20 V/cm) were applied via he line electrodes during the action potential of the 20th S1 at wo different coupling intervals (S1S2: 120 and 180 ms).

Preparation of Polyvinylchloride Nanofiltration Membrane: Investigation the Effect of Thickness, Prior Evaporation Time and Addition Polyethylenglchol as Additive on Membrane Performance and Properties
In this work, polyvinylchloride (PVC) membrane prepared via casting solution technique and phase inversion method. N, N dimethylacetamide (DMAC) was used as primary solvent and Tetrahydrofuran (THF) was used as a co-solvent. The effects of parameters such as membrane thickness, evaporation time of casting film before immersion precipitation and addition of polyethylenglchol (PEG) on PVC membran...
متن کاملSynchronized repolarization after defibrillation shocks. A possible component of the defibrillation process demonstrated by optical recordings in rabbit heart.
BACKGROUND It is currently believed that defibrillation shocks act primarily by stimulating excitable myocardium to abolish wave fronts. Recent studies have shown that shocks applied during pacing not only stimulate excitable myocardium but also prolong the depolarization and refractoriness of myocardium already in a depolarized state. This study investigates the effects of shocks on fibrillati...

متن کاملLead-Lag Controllers Coefficients Tuning to Control Fuel Cell Based on PSO Algorithm
One of the most important Fuel cells (FCs) is Proton Exchange Membrane Fuel Cells (PEMFCs). The outputvoltage of this FC depends on current loads. This paper tries to introduce, implement and control the voltage ofPEMFC, during load variations. The output voltage of fuel cell should be constant during load variation. Toachieve this goal, a controller should be designed. Here, the Lead-Lag contr...
