This centrifugal pump (CP) includes two parts: the blood pump and the driving apparatus. They are connected by six twin magnetic disc plates and driven by a magnetic DC motor (120W). The blood pump had six leaves deadlocked between two plastic discs. Six leaves were set at 30 degrees angles, separately. In the lower chamber of the CP, there was an inlay magnetic disc, which is connected with th...

The magnetohydrodynamic (MHD) is the study of the interaction of electrically conducting fluids and electromagnetic fields. This paper presents the numerical modelling of the coupling electromagnetichydrodynamic phenomena using the Finite volume Method (FVM) in cylindrical coordinate and the stream vorticity formulation ξ, ψ in two-dimensional in an annular induction MHD pump. The magnetic indu...

A sealless pump, also known as a wet rotor pump or canned requires stationary sleeve in the air gap to protect stator from medium that flows around and impeller. Since is typically made non-magnetic electrically conductive material, time-varying magnetic flux density creates an eddy current loss sleeve. Precise assessment of this crucial for design pump. This paper presents method calculating s...

Abstract The availability of sub 100 fs short and highly intense free-electron laser (FEL) pulses allows for new insights in laser-induced ultrafast demagnetization (LID) ferromagnetic thin films on nanometer length scales. We designed a pair in-vacuum Helmholtz coils, providing pulsed magnetic fields up to µ 0 H z = ±45 mT, time-resolved experiments at FEL sources transmission geometry. report...

BACKGROUND Conventional cardiopulmonary bypass results in cerebral ischemic sequelae that may be reduced with hybrid pump technologies, such as the CardioVention system (CardioVention, Santa Clara, CA, USA). CardioVention differs from conventional bypass in that it has a novel air elimination module and reduced membrane surface area and priming volume. This preliminary study tested whether this...

Cancer patients with severe refractory pain are often managed with implantable drug delivery systems (IDDS). The only drugs with US Food and Drug Administration approval for intrathecal use are morphine, ziconotide, and baclofen. Other drugs used and mixed include, hydromorphone, bupivacaine, sufentanil, and fentanyl. These patients often undergo magnetic resonance imaging (MRI) for disease-rel...

A parametrically amplified ring detector for magnetic resonance imaging (MRI) is presented. The system consists of eight coupled PCBs arranged as an octagon. Each carries three L-C resonators, for signal, idler and pump frequencies. Adjacent signal resonators and pump resonators are magnetically coupled, so these two frequencies propagate as magneto-inductive waves; however, the idlers are unco...

We demonstrate experimentally ultrafast all-optical switching in subwavelength nonlinear dielectric nanostructures exhibiting localized magnetic Mie resonances. We employ amorphous silicon nanodisks to achieve strong self-modulation of femtosecond pulses with a depth of 60% at picojoule-per-disk pump energies. In the pump-probe measurements, we reveal that switching in the nanodisks can be gove...

Many implantable systems have been designed for long-term, pulsatile delivery of insulin, but the lifetime of these devices is limited by the need for battery replacement and consequent replacement surgery. Here we propose a batteryless, fully implantable insulin pump that can be actuated by a magnetic field. The pump is prepared by simple-assembly of magnets and constituent units and comprises...
