Influence of Nanoparticles Phenomena on the Peristaltic Flow of Pseudoplastic Fluid in an Inclined Asymmetric Channel with Different Wave Forms
The influence of nanofluid with different wave forms in the presence of inclined asymmetric channel on peristaltic transport of a pseudoplastic fluid is examined. The governing equations for two dimensional and two directional flows of a pseudoplastic fluid along with nanofluid are modeled and then simplified under the assumptions of long wavelength and low Reynolds number approximation. The ex...
متن کاملTransthoracic Ventricular Defibrillation with Triangular and Trapezoidal Waveforms
From 7,200 fibrillation-defibrillation episodes in anesthetized dogs, the effectiveness of 6 classes of unidirectional shocks in reversing ventricular fibrillation of 30-sec duration was determined. The shocks lasted for 1 to 256 msec. Three waveforms (ascending ramp triangular, descending ramp triangular, and trapezoidal) were studied at peak currents of 10 amp and 20 amp. Families of curves o...
متن کاملStrength-duration curves for ventricular defibrillation in dogs.
The threshold voltage and current necessary for ventricular defibrillation was measured in dogs using capacitor-discharge and half-sinusoidal pulses of current of various durations. From these quantities the electrical strength required for defibrillation was determined and expressed as energy, peak current, and charge per gram of heart. The optimum current duration depends on the criterion sel...
متن کاملElevation of ventricular defibrillation threshold in dogs by antiarrhythmic drugs.
Effects of antiarrhythmic drugs upon the threshold delivered energy (TDE) and threshold peak current (TPC) for electrical ventricular defibrillation by damped sinusoidal shocks were investigated in 25 pentobarbital-anesthetized dogs. TDE and TPC were increased by the three antiarrhytmic drugs tested. Bolus injections produced a transient rise and continuous infusions produced a steady rise in d...
