Breaking Kelvin: Circulation conservation and vortex breakup in MHD at low Magnetic Prandtl Number

open access: yes, 2018
In this paper we examine the role of weak magnetic fields in breaking Kelvin's circulation theorem and in vortex breakup in two-dimensional magnetohydrodynamics for the physically important case of a low magnetic Prandtl number (low $Pm$) fluid.

Dynamical chemical labelling to profile circulating micrornas in body fluids

open access: yes, 2021
En los últimos años, son numerosos los estudios que se han expandido rápidamente en búsqueda de varios marcadores bioquímicos. Los biomarcadores se definen como moléculas que detectan o confirman la presencia de una condición fisiopatológica, permitiendo así establecer un diagnóstico, un mejor pronóstico, e incluso modificar un tratamiento.

Dynamics of the Thermohaline Circulation under Wind forcing

open access: yes, 2001
The ocean thermohaline circulation, also called meridional overturning circulation, is caused by water density contrasts. This circulation has large capacity of carrying heat around the globe and it thus affects the energy budget and further affects the ...

Modeling of integrated fluid dynamics of cerebral circulation and cerebrospinal fluid flow

open access: yesModeling of integrated fluid dynamics of cerebral circulation and cerebrospinal fluid flow
Objectives:In the fluid dynamics of cerebral circulation and cerebrospinal fluid (CSF) motion, the computational simulation model has not been established. We conducted the multi-scale simulation in the cerebral circulation model. Therefore, we would like to integrate these two different fluid dynamics models.

DYNAMIC STUDY ON CEREBROSPINAL FLUID CIRCULATION AFTER SUBARACHNOID HEMORRHAGE

open access: yesDYNAMIC STUDY ON CEREBROSPINAL FLUID CIRCULATION AFTER SUBARACHNOID HEMORRHAGE
Alterations in the cerebrospinal fluid (CSF) circulation after subarachnoid hemorrhage (SAH) were examined in 19 patients. Sources of hemorrhage were aneurysm in 17 cases, arteriovenous aneurysm in one and unknown in one. Cistenography was performed using 1 mCi of 169Yb diethyltriaminepentaacetic acid which was given intrathecally by lumbar injection ...
