amniotic fluid volume (afv) is one of the important parameters in the assessment of fetal well-being. the ability of ultrasound measurements to represent the actual afv is unproven. this study was undertaken to compare correlation of conventional amniotic fluid index (afi) and radial amniotic fluid index (rafi) as a new method with actual fluid volume on phantom. as an experimental study, 10 to...

Mobile charge in an electrolytic solution can principle be represented as the divergence of ionic polarization. After adding explicit solvent polarization a finite volume electrolyte then treated composite non-uniform dielectric body. Writing electrostatic interactions integral over electric field energy density we show that Poisson-Boltzmann functional this formulation is convex and used to de...

this article introduces a new tri-parameter law of corresponding states from the known regularities, namely the lir and zeno line for dense fluids (when tz=tc). two of these parameters are the zeno line parameters and the third parameter (the fluid parameter), has been obtained from the lir, this parameter is solely dependent upon the fluid characteristics. the third parameter can be obtaind fr...

The strain energy function of hyperelastic material models must fulfill some mathematical conditions to satisfy requirements such as numerical stability and physically plausible mechanical behavior. In the framework computer simulations with Newton-type methods, is assured by positive definiteness tangent operator. Baker-Ericksen inequalities, on other hand, are sufficient necessary in order gu...
