A lightweight magnetically shielded room with active shielding [PDF]

Scientific Reports, 2022
AbstractMagnetically shielded rooms (MSRs) use multiple layers of materials such as MuMetal to screen external magnetic fields that would otherwise interfere with high precision magnetic field measurements such as magnetoencephalography (MEG). Optically pumped magnetometers (OPMs) have enabled the development of wearable MEG systems which have the ...

THE PILE SHIELD. [PDF]

JAMA: The Journal of the American Medical Association, 1902
It has often happened, even in the best hands, that the patient has been severely burned, when the ordinary clamp and cautery method has been employed in the operation for piles, causing the surgeon no end of annoyance. To avoid this, I have devised a little instrument that eliminates such accidents; this instrument is small, inexpensive, portable ...

Geochemistry of Kauai shield-stage lavas: Implications for the chemical evolution of the Hawaiian plume [PDF]

, 2003
We measured He, Sr, Nd, Pb, and Os isotope ratios and major and trace element concentrations in stratigraphically and paleomagnetically controlled shield-stage lavas from Kauai, Hawaii. The range of 3He/4He ratios (17–28 RA) from Kauai is similar to that
