A permanent magnet, gradient coils, radiofrequency coil, and shim coil were installed in a temperature variable thermostatic bath.
A wet belt permanent high gradient magnetic separator (referred here as WBHGMS) was developed on the principle of HGMS in an inclined slurry flow of several centimeters thick.
So, the permanent magnetic MRI gradient coil can be designed by target field method.
We compare measured magnetization responses to various standard shaped pulses under extreme conditions of application (∼30 μs duration, offset frequencies up to 0.3 MHz, and in the presence of a 13 T/m permanent magnetic field gradient).
We introduce a simple, efficient, low-SAR method for magnetic resonance imaging in the presence of a static field with a permanent, and possibly large gradient.
The integration of a modified induction cold crucible and a gradient heatable permanent metallic mold in a centrifugal casting furnace under vacuum are the main features of this process.
Additionally we build up laboratory setups with electromagnets and strong permanent magnets to study gradient induced effects and B0 dependencies in more detail.
As part of a larger study seeking to understand the dynamics of plant communities in response to different prescribed fire regimes, we measured the functional traits of the understory plant communities located in over 140 permanent plots spanning strong gradients in soil moisture in a pyrogenic longleaf pine forest in North Carolina, USA, over a four-year period from 2011 and 2014.
In this study, we reported that the magnetic force is the dominant force in collection of ferromagnetic particles of mobility equivalent size larger than or equal to 50 nm in a high-gradient permanent-magnetic aerosol collector, while the diffusiophoretic force is responsible for particles smaller than 10 nm.
A gradient of agricultural intensification (from permanent meadows to permanent crops, with rotation crops and meadows as intermediary steps) was studied in the course of the RMQS-Biodiv program, covering a regular grid of 109 sites spread over the whole area of French Brittany.
