Transport of cross helicity and radial evolution of alfvenicity in the solar wind [PDF]

open access: yes, 2004
A transport theory including cross helicity, magnetohydrodynamic(MHD) turbulence, and driving by shear and pickup ions, is applied to the radial evolution of the solar wind.

Collisional and viscous damping of MHD waves in partially ionized plasmas of the solar atmosphere [PDF]

open access: yes, 2004
Magnetohydrodynamic (MHD) waves are widely considered as a possible source of heating for various parts of the outer solar atmosphere. Among the main energy dissipation mechanisms which convert the energy of damped MHD waves into thermal energy are ...

On the relationship between equilibrium bifurcations and ideal MHD instabilities for line-tied coronal loops [PDF]

open access: yes, 2010
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated, imposing line-tied boundary conditions.

Effect of heat source/sink on MHD start-up natural convective flow in an annulus with isothermal and isoflux boundaries

open access: yesArab Journal of Basic and Applied Sciences, 2020
This article examines the influence of isothermal and isoflux heating/cooling with heat source/sink on unsteady hydromagnetic-free convective flow of a viscous incompressible fluid in an annulus.

Numerical Study of a Liquid Metal Oscillating inside a Pore in the Presence of Lorentz and Capillary Forces

open access: yesFluids, 2020
In order to ensure stable power exhaust and to protect the walls of fusion reactors, liquid metals that are fed to the wall surface through a capillary porous system (CPS) are considered as alternative plasma-facing components (PFCs).

Wave propagation, phase mixing and dissipation in Hall MHD [PDF]

open access: yes, 2012
In this thesis the effect of the Hall term in the generalised Ohm’s law on Alfvén (shear) and fast wave propagation and dissipation in the ion cyclotron frequency range is investigated.

Anisotropic MHD turbulence [PDF]

open access: yesAIP Conference Proceedings, 2007
The solar wind and the interstellar medium are permeated by large-scale magnetic fields that render magnetohydrodynamic (MHD) turbulence anisotropic. In the weak-turbulence limit in which three-wave interactions dominate, analytical and high-resolution numerical results based on random scattering of shear-Alfvén waves propagating parallel to a large ...

Seasonality of scabies and its association with climatic factors in Rohingya refugee camps, Cox’s Bazar: a retrospective observational study, 2021–2023

open access: yesBMJ Open
Background Scabies is a common skin condition and poses a substantial disease burden in resource-poor tropical settings. The Rohingya refugee camps in Cox’s Bazar, Bangladesh represent one of the world’s largest and most protracted humanitarian crises ...
