The dependence of the viscosity-parameter on the disk scale height profile

open access: yes, 2007
It is shown that the height scale for accretion disks is a constant whenever hydrostatic equilibrium and sub-sonic turbulence regime hold in the disk.

Variable Thermal Conductivity and Viscosity Flow past a Stretching Porous Surface with Viscous Dissipation through a Porous Medium [PDF]

open access: yes, 2014
In this work, we study variable thermal conductivity and viscosity flow past a porous surface with viscous dissipation through a porous medium. We transformed the governing partial differential equations into ordinary differential equations in terms of a

Dual solutions of a boundary layer problem for MHD nanofluids through a permeable wedge with variable viscosity

open access: yesBoundary Value Problems, 2017
Considering the effect of variable viscosity and the phenomenon of flow separation, the MHD Cu/Ag-Water nanofluids through a permeable wedge are investigated.

The effects of variable viscosity on the decay of homogeneous isotropic turbulence [PDF]

open access: yesPhysics of Fluids, 2014
In this paper, we investigate the decay of incompressible homogeneous isotropic turbulence in a variable viscosity fluid. The viscosity coefficient is assumed to depend linearly on a scalar, representing either a temperature or a concentration, and obeying a simple advection-diffusion equation.

Viscous Dark Energy Models with Variable G and Lambda

open access: yes, 2007
We consider a cosmological model with bulk viscosity ($\eta$) and variable cosmological $(\Lambda\propto \rho^{-\alpha}, \alpha=\rm const.$) and gravitational ($G$) constants. The model exhibits many interesting cosmological features.

Effects of Variable Viscosity and Temperature Modulation on Linear Rayleigh-Bénard Convection in Newtonian Dielectric Liquid [PDF]

open access: yes, 2019
The linear Rayleigh-Bénard electro-convective stability of the Newtonian dielectric liquid is determined theoretically subject to the temperature modulation with time.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

The vagaries of variable viscosity convection

open access: yesGeophysical Research Letters, 1980
The wavelength dependence of convection with a temperature dependent viscosity is studied using two‐dimensional finite difference models. A steady state solution with a horizontal wavelength of eight times the depth is found to transport heat more efficiently than a solution with exactly the same parameters but with a wavelength of twice the depth ...

If it does not help, it might hurt: Pharmacodynamics of a second IVIg course in Guillain–Barré syndrome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objectives Intravenous immunoglobulin (IVIg) is an effective treatment for Guillain–Barré syndrome (GBS), but recovery varies between patients. This study aims to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of a single and a second IVIg dose (SID) in patients with GBS.
