3-Methylindole (3 MI) is a selective pulmonary toxicant, and cytochrome P450 (P450) bioactivation of 3 MI, through hydroxylation, epoxidation, or dehydrogenation pathways, is a prerequisite for toxicity. CYP2F1 and CYP2F3 exclusively catalyze the dehydrogenation of 3 MI to 3-methyleneindolenine, without detectable formation of the hydroxylation or epoxidation products. It was not known whether ...

Primary ionization is created inside the gas gap of a small size ð10 20 cmÞ RPC, analogous to the RPC of the ATLAS muon detector, by focusing a pulsed (width p0:5 ns) nitrogen laser beam (transverse diameter E15 mm). With this set-up we can characterize the behaviour of the RPC by measuring such parameters as drift velocity and gas amplification. For an ATLAS-like gas mixture (97% C2H2F4; 3% is...

Results of beam tests are reported: the so-called ‘‘efficiency puzzle’’ is investigated using a 0:1 mm gap GRPC operated at different pressures for isobutane gas. The influence of edge effects on the time-response function is studied for a ð4 0:3 mmÞ-gap GRPC disk of 5 cm diameter and found to have negligible influence on resolution and tails. A design of large-scale array is elaborated for exp...
