In previous paper the authors successfully developed a vibration suppression device (VSD) that has variable moment of inertia using Magneto-Rheological (MR) fluid. The MR fluid is filled into flywheel. Ferrite particles are clustered when magnetic field applied to flywheel by electromagnets, series mass VSD will be switchable. this seismic tests during switching reinforcement learning focused i...

MR was performed on 23 formalin-fixed brain specimens of patients 60 years old or older at the time of death. In two of these subjects MR had also been performed in vivo prior to death. Fifteen hyperintense white-matter foci were found on long TR MR images in seven brains. These lesions were correlated with gross and microscopic pathology. Six lesions were infarctions, two were small foci of gl...

A major determinant of the success of surgical vascular modifications, such as the total cavopulmonary connection (TCPC), is the energetic efficiency that is assessed by calculating the mechanical energy loss of blood flow through the new connection. Currently, however, to determine the energy loss, invasive pressure measurements are necessary. Therefore, this study evaluated the feasibility of...

BACKGROUND AND PURPOSE Some patients with SIH have fast CSF leaks requiring dynamic CTM for localization; however, patients generally undergo conventional CTM before a dynamic study. Our aim was to determine whether findings on head MR imaging, spine MR imaging, or opening pressure measurements can predict fast spinal CSF leaks. MATERIALS AND METHODS A retrospective review was performed on 15...

To investigate the unsteady flow field generated by magnetorheological (MR) fluid of a high-speed laminar boundary layer in narrow-long gap absorber (MRA), new numerical model is proposed. The has magnetic-field-activated and inactivated regions, with MR flowing as bi-viscous (non-Newtonian) Newtonian fluid. described incompressible governing partial differential equation (PDE) initial-boundary...

The aggregation of magnetic particles in the presence of a magnetic field is the basic phenomenon which underlies all the physics of magnetorheological (MR) fluids. Although these interactions are well understood when the suspending fluid is a simple liquid, new MR fluids based on dispersion of magnetic microparticles in a ferrofluid or MR elastomers based on dispersion of magnetic particles in...

The prevalence of Japanese encephalitis (JE) is not uncommon in Taiwan. It tends to occur in the summer and early autumn. The definite diagnosis of JE was according to the results of serological examination and clinical presentation. We report the magnetic resonance (MR) imaging findings of two patients with serologically proved JE. The MR imaging demonstrated bilateral thalamic involvement wit...

This paper presents a new design of multi-disks Magnetorheological braking system (MR brake) for automotive application considering the magnetic saturation in both electromagnetic core and MR fluid. A one dimensional analytical model is developed to calculate the braking torque of the proposed system. The geometry of the system, which is created in of elements near the AutoCAD®, is discretized ...

Increasing hepatobiliary laparoscopic surgeries have lead to a rise in injury to the biliary tree and other complications like bile leak. Ultrasonography (US) and computed tomography (CT) cannot reliably distinguish bile from other postoperative fluid collections. Magnetic resonance (MR) imaging with hepatobiliary agents and MR cholangiopancreatography provide anatomic and functional informatio...

Lymphocytes from the synovial fluid of eight out of eight rheumatoid arthritis (RA) patients had elevated very late activation antigen-1 (VLA-1) expression (10-36% positive cells), whereas peripheral blood lymphocytes (PBL) from RA patients and healthy controls had low VLA-1 expression (0-6% positive cells). During 1-2 wk of in vitro culture, VLA-1 increased on synovial fluid cells but remained...
