Frequency analyzer for bioelectric potential in the sub-audio range


, : Frequency analyzer for bioelectric potential in the sub-audio range. Rev Sci Instruments 20(8): 612-616

This instrument is coupled to the output of a standard eeg. amplifier and records 20 frequencies by means of individual filters each coupled to a 2-inch cathode-ray oscilloscope. A 35 mm. slow moving camera provides a time base while simultaneously photographing the filter deflections, a CR trace of the unanalyzed slow wave, and 1 sec. markers produced by a clock driven flashing light.

Increasing evidence suggests that osteocalcin (OC), one of the osteoblast-specific proteins, has been associated with atherosclerosis, but results are conflicting. The aim of this study was to elucidate the independent effect of uncarboxylated ost...

In phytotron studies, (a) green panic and (b) Setaria anceps [=S. sphacelata var. sericea] were grown at 20, 25 or 30 deg C. Inflorescence development of (a) was fastest at 25 deg and heading rate was similar in all tillers, while in (b) flowering...
