S U M M A R Y We examine the effects of rheological layering on post-seismic deformation using models of an elastic layer over a viscoelastic layer and a viscoelastic half-space. We extend a general linear viscoelastic theory we have previously proposed to models with two layers over a half-space, although we only consider univiscous Maxwell and biviscous Burgers rheologies. In layered viscoela...

Pulsatile motion of blood in a circular tube of varying cross-section has been developed by considering slip flow at the tube wall and the blood to be a non- Newtonian biviscous incompressible fluid. The tube wall is supposed to be permeable and the fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the tube wall. The tangential velocity of the fl...

The analysis of GRACE gravity data revealed postseismic gravity increase by 6 μGal over a 500 km scale within a couple of years after the 2011 Tohoku-Oki earthquake, which is nearly 40-50% of the coseismic gravity change. It originates mostly from changes in the isotropic component corresponding to the Mrr moment tensor element. The exponential decay with rapid change in a year and gradual chan...

Abstract. We present a finite-element model of post-seismic solid Earth deformation built in the software package Abaqus (version 2018). The is global and spherical, includes self-gravitation for purpose calculating far field (>∼300 km) major earthquakes. An earthquake simulated by prescribing slip on fault plane mesh relaxes under resulting change stress. Both linear Maxwell biviscous (Burg...

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...

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...

fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...
