The use of a continuity equation of fluid mechanics to reduce the abnormality of the cardiovascular system: A control mechanics of the human heart

The paper is aimed at presenting the differential equations for the cardiovascular system with the help of continuity equation of fluid mechanics to reduce the abnormality of the rate of blood flow and variation of blood volume in different parts of the system. The equations are used to explain the Frank-Starling mechanism, which plays an important role in the maintenance of the stability of the distribution of blood in...

Using electrical impedance tomography in following up skin conductivity change for different sonophoresis conditions

Sonophoresis is the using of ultrasound waves to increase the entrancement of genes and drugs surpassing the skin barrier. Many mechanisms have been described to illustrate the sonophoresis mode of action; some describe changes in skin resistance during sonophoresis. Electrical impedance tomography (EIT) technique uses voltage measurement through a group of electrodes and reconstructs the data to a conductivity picture....
