Detection of several targets (U, Be , D 2 O) interest to national security has been achieved at Purdue University’s 6 MV X-ray clinical linear accelerator (CLINAC), from photoneutron/fission induced neutron signatures using a Centrifugally Tensioned Metastable Fluid Detector (CTMFD). Traditional detection schemes were saturated and ineffective under the intense (to ∼ 10 4 R/h) photon environmen...

We have recently reported’ the inhibition of xanthopterin oxidase and xanthine oxidase by synthetic pteroylglutamic acid (PGA). However, since an exceptionally pure sample2 of PGA, which was later examined, possessed less than one-sixth of the inhibitory power previously observed, it appears possible that the effect is due to traces of a contaminant. The observation by Lowry and Bessey3 that 2-...
