MMP-9 DEFICIENT DENDRITIC CELLS HAVE IMPAIRED MIGRATION THROUGH TRACHEAL EPITHELIAL TIGHT JUNCTIONS

A system for readily determining the magnetic orientation of permanent magnets for mass assembly in a predetermined orientation into electronic or mechanical devices, the system comprises a first movable conveyor having a first surface which is magnetically polarized in a predetermined orientation. The magnets are individually placed on the first conveyor by a second conveyor which, in association with the first conveyor, orients the magnets in a preferred orientation on the first conveyor. A motor for moving the first conveyor is attached to it for passing the magnets through a mass production assembly.
