Influence of external magnetic field on the tribological performance of magnetic fluids in different lubrication regimes

open access: yesFriction
Magnetic fluids (MFs) represent a unique class of smart functional lubricating materials, with their physical properties tunable by the application of a magnetic field.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory

open access: yes, 2013
The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...

Metabolic and Microvascular Risk Factors Associated With Brain Health in Type 1 Diabetes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We examined relationships between metabolic factors, microvascular complications, and brain health in adults with type 1 diabetes. Fifty‐one adults were assessed for metabolic risk factors, microvascular complications, and cognitive function, with a subset completing brain MRI.

Effect of flow development region and fringing magnetic force field on annular split-flow thin fractionation

open access: yes, 2004
Split-flow thin (SPLITT) fractionation devices have been widely used to separate macromolecules, colloids, cells and particles. Recently, the quadrupole magnetic flow sorter (QMS) has been reported in the literature as another family of SPLITT ...

EFFECT OF SLIP VELOCITY ON MAGNETIC FLUID LUBRICATION OF ROUGH POROUS RAYLEIGH STEP BEARING [PDF]

open access: yesJournal of Mechanical Engineering and Sciences, 2013
This article aims to analyze the performance of a magnetic-fluid-based porous rough step bearing considering slip velocity. The Neuringer-Rosensweig model governs the fluid flow while the velocity slip is modeled by the method of Beavers and Joseph.
