Different animal models for peritoneal dialysis (PD) have been used in the past decades to develop PD fluids compatible with patient life and to identify markers of peritoneal fibrosis and inflammation. Only few of those studies have taken into account the importance of uraemia-induced alterations at both systemic and peritoneal levels. Moreover, some animal studies which have reported about PD...

A model of the lattice Boltzmann method for non-Newtonian fluids was constructed. The shear stress of purely viscous but non-elastic non-Newtonian fluid is a function of shear rate only. For the power-law model, only two constant parameters can cover shear-thinning and shear-thickening fluids. Two power-law models are introduced to the finite difference lattice Boltzmann method. One is a model ...

The influence of non-Newtonian fluid behavior on the flow statistics turbulent bubble-laden downflow in a vertical channel is investigated. A Direct Numerical Simulation (DNS) study conducted for power-law fluids with indexes 0.7 (shear-thinning), 1 (Newtonian) and 1.3 (shear-thickening) liquid phase at gas volume fraction 6%. driven downward by constant volumetric rate corresponding to frictio...

introdouction: cone-beam computed tomography (cbct) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. the aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the cbct technique. materials and methods: in this retrospective study, a total of 105 case...

The Boulder-Lefroy shear zone, developed in the ca. 2.7 to 2.65 Ga Archean greenstone sequence of the Kalgoorlie terrane in the Yilgarn craton, is remarkable for the number and importance of gold deposits it hosts. These include, from south to north, the following gold districts (with tons of contained Au): St Ives (253 t), Hampton-Boulder-Jubilee (123 t), Golden Mile (1,821 t) plus Mount Charl...

A new pressure sensor array, positioned on the bottom plate of a standard torsional rheometer, is presented. It built from unique piezo-capacitive polymeric foam and consists 25 capacitive sensors (of surface 4.5 × mm 2 each) together in 5 regular array. The array used to obtain mapping normal stresses complex fluids, which dramatically extends capability rheometer. We demonstrate this with thr...

The simulation of flows of viscoelastic fluids is a very challenging domain from the theoretical as well as the numerical modelling point of view. In particular, all the existing methods have failed to solve the high Weissenberg number problem (HWNP). It is therefore clear that new tools are necessary. In this thesis we propose to tackle the problem of the simulation of viscoelastic fluids pres...

During the past few decades, interest in understanding peculiar rheological behavior of shear-thickening fluids has increased due to their potential use various commercial applications. In such an endeavor, optimal design these is essential, which necessitates our in-depth properties from a modeling perspective. We herein introduce continuum model predict polymer solutions using non-equilibrium...
