This article discusses a possible approach to creating a calibration technique for the Galactic and Solar Cosmic Proton Cherenkov Detector. The method is based on the Monte Carlo simulation of proton and electron transfer and their generation of Cherenkov photons in the polymethylmethacrylate radiator. It is shown that, under certain conditions, the device calibration with electrons of 9,38 MeV energy is equivalent to the calibration with a 600 MeV proton beam incident laterally on the detector.

The decarboxylation of 3, 4-dihydroxyphenyl-alanine (Dopa) to dopamine has been shown previously in animal and human tissues in both in vitro and in vivo studies (Sourkes, 1966; Vogel et al., 1970). However, very little information is available as to whether or not the decarboxylation of Dopa occurs in human red blood cells (RBC). In the present experiment we demonstrated this change in RBC from normals and from schizophrenics. An ionization chamber method was used for an instantaneous and continuous measurement of 14CO2 production from DL-dopa-carboxyl-14C by RBC in vitro.
