This study presents the computational analysis of three dimensional Casson and Carreau nanofluid flow concerning the convective conditions. To do so, the flow equations are modified to nonlinear system of ODEs after using appropriate self-similarity functions. The solution for the modified system is evaluated by numerical techniques. The results show the impacts of involving variables on flow c...

In this paper, an analytic solution to the scattering of water wave by submerged permeable breakwaters in infinite-depth is presented. The velocity field around breakwater under linear train deep condition sought formulating a nonhomogeneous Riemann-Hilbert problem. To deal with nonlinearity due permeability plates, perturbation method applied terms small parameter representing permeability. We...

A combined physiological and morphological study of the effects of cytochalasin B (CB) on the toad urinary bladder has been carried out. CB inhibits the hydro-osmotic response to vasopressin without altering basal water permeability or diffusion, or the increase in (3)H(2)O diffusion observed after hormone addition. Although CB increases [(22)Na]-, [(36)Cl]-, and [(14)C]urea fluxes, and decreas...

Diffusion anisotropy is the most fundamental and important parameter in the description of cardiac fibers using diffusion tensor magnetic resonance imaging (DTI), by reflecting the microstructure variation of the fiber. It is, however still not clear how the diffusion anisotropy is influenced by different contiguous structures (collagen, cardiac myocyte, etc.). In this paper, a virtual cardiac ...

This paper addresses one of the major challenges in water-flooded oil reservoirs, which is early water breakthrough due to the presence of high permeable layers in the media. COMSOL Multiphysics is used to model two phase (water and oil) flow in dual-permeability porous medium at micro-scales. The heat transfer module is coupled with the laminar two-phase flow interface, because temperature aff...

Introduction: Dynamic contrast enhanced MRI (DCE-MRI) with tracer kinetic modeling has been proposed as a biomarker of tumor angiogenesis assessment in humans. Several tracer kinetic models, distributed parameter model (DP), St. Lawrence and Lee model (ATH), and conventional compartmental model (CC), have been proposed to calculate permeability-surface area product (PS). It was found that PS co...

A computer laboratory has been designed to teach the osmotic properties of cells. One program, CELL.BA, is for the teacher to enter values for the volume of cell water and osmotically inactive material, the concentration of impermeant solute in the cell, and the permeability of the plasma membrane to water and a nonelectrolyte. When the program is protected, students use it as a cell with unkno...

MOTIVATION Determination of drug absorption is an important component of the drug discovery and development process in that it plays a key role in the decision to promote drug candidates to clinical trials. We have developed a method that, on the basis of an analysis of the dynamic distribution of water molecules around a compound obtained by molecular dynamics simulations, can compute a parame...

Polycrystalline samples of Cd substituted cobalt ferrites with composition Co1-xCdxFe2O4 (x = 0.00.6 in steps of 0.1) were prepared by double sintering ceramic method. The samples were sintered at 1050°C for 3 hours. X-ray diffraction pattern of the samples showed single phase cubic spinel structure. It was found that the lattice parameter increases linearly with increasing Cd content following...
