One of the major hazards facing the livestock industries in food safety is commensal gut microorganisms (e.g. Escherichia coli, Listeria monocytogenes, Yersinia enterocolotica, Campylobacter spp. and Salmonella spp.), which contaminate animal products and cause illness in humans. Traditionally, pathogenic gut microorganisms have been controlled by antibiotic growth promoters [8]. Use of such supplements...
The following paper describes the results of ionizing dose rate investigations into upset, supply photocurrent, latch-up, and burnout susceptibility of the Xilinx Virtex IV XC4VFX12. All investigations were performed on a commercial version of the device. The maximum no-upset dose rate was 2.8times108 rad(Si)/s. Photocurrent amplitudes as a function of dose rate were recorded.
Summary form only given. We have experimentally investigated the potential of narrow coherent population trapping resonances for precision applications like magnetometry or atomic frequency standards. CPT can be observed in /spl Lambda/ systems where two ground states are coupled to a common excited state by two near-resonant light fields. Effective formation of ground state coherences takes place...
