Noninertial feedback detection of a random process using a Schottky diode with δ-doping

The problem of determining the average value and dispersion of the process during the noninertial detection of a random stationary process, with the feedback taken into account, using a Schottky diode with δ-doping is investigated. The dependence of the output parameters on the input ones has been obtained in the Gaussian approximation.     

Reaction of ethyl 9-thioacridonyl-10-acetate with hydrazine

The reaction of ethyl 9-thioacridonyl-10-acetate with hydrazine hydrate gives the corresponding ethyl hydrazonoacridonyl-10-acetate, which readily undergoes a reaction with aldehydes and on heating in DMF reacts with hydrazine hydrate to form 9-ylidenehydrazonoacridonyl-10-acetic acid hydrazide. The latter undergoes a condensation reaction with aldehydes to form ylidenehydrazides of acridonyl-10-acetic acid 9-ylidenehydrazones. The structures of these compounds have been confirmed by UV, IR, PMR, and mass spectrometry.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 525–527, April, 1989.
