Brain White-Matter Degeneration Due to Aging and Parkinson Disease as Revealed by Double Diffusion Encoding [PDF]

open access: yesFrontiers in Neuroscience, 2020
Microstructure imaging by means of multidimensional diffusion encoding is increasingly applied in clinical research, with expectations that it yields a parameter that better correlates with clinical disability than current methods based on single ...

Fluctuations of Temperature and Thermal Energy in the Place of Double Diffusion Structures in the Strait of Hormuz [PDF]

open access: yesNīvār, 2022
Double Diffusion Convection (DD) structures, in two types of Salt-Fingering (SF) and Diffusive Convection (DC), occur due to vertical temperature and salinity gradients with different diffusion coefficients.

Double-diffusive Magnetic Layering [PDF]

open access: yesThe Astrophysical Journal, 2021
Abstract Double-diffusive systems, such as thermosolutal convection, in which the density depends on two components that diffuse at different rates, are prone to both steady and oscillatory instabilities. Such systems can evolve into layered states, in which both components, and also the density, adopt a “staircase” profile. Turbulent

Double-diffusive natural convection in a trapezoidal solar pond with discrete heat boundary conditions: Effects on non-convective zones

open access: yesJournal of Thermal Science and Technology, 2021
A three-dimensional numerical study is conducted to investigate the double-diffusive natural convection inside a trapezoidal solar pond filled with water and salt solution and subjected to discrete heat boundary conditions. It investigates the effect of

Nonlinear Mixed Convective Flow over a Moving Yawed Cylinder Driven by Buoyancy

open access: yesMathematics, 2021
The fluid flow over a yawed cylinder is useful in understanding practical significance for undersea applications, for example, managing transference and/or separation of the boundary layer above submerged blocks and in suppressing recirculating bubbles ...

Mixed convective eyring-powell ferro magnetic nanofluid flow suspension towards a stretching surface with buoyancy effects through numerical analysis

open access: yesFrontiers in Materials, 2023
This article examines the impact of buoyancy on the magnetic Eyring-Powell nanofluid flow toward a stretching surface. Coupled similarity equations are created from the governing flow equations.

Effect of Thermal Radiation and Double-Diffusion Convective Peristaltic Flow of a Magneto-Jeffrey Nanofluid through a Flexible Channel

open access: yesMathematics, 2022
The noteworthiness of double-diffusive convection with magneto-Jeffrey nanofluid on a peristaltic motion under the effect of MHD and porous medium through a flexible channel with the permeable wall has been theoretically examined.

Double-diffusive convection

open access: yesEAS Publications Series, 2013
Much progress has recently been made in understanding and quantifying vertical mixing induced by double-diffusive instabilities such as fingering convection (usually called thermohaline convection) and oscillatory double-diffusive convection (a process closely related to semiconvection).
