Previous study has shown that niridazole (NDZ) is dysmorphogenic to rat embryos between days 10 and 11 under culture conditions including 5% oxygen. Other studies have found that reductive embryonic biotransformation is required but that covalent binding is not a major basis of this embryotoxicity. In research presented here, NDZ exposure of homogenates(More)
We have performed a variety of precision measurements by comparing ac and dc waveforms generated by two independent ac programmable Josephson voltage standard (ACPJVS) systems. The objective of these experiments was to demonstrate the effectiveness of using a sampling digital voltmeter to measure small differences between Josephson waveforms for frequencies(More)
The Josephson arbitrary waveform synthesizer can be used as a precision voltage source for both ac and dc signals. Recent improvements in circuit designs have resulted in output voltages greater than 100 mV rms for ac metrology measurements in the frequency range from 1 to 50 kHz. In this paper, we present measurements of several significant error sources(More)
