Spectral analysis of Doppler ultrasonic flow signals by a personal computer


, : Spectral analysis of Doppler ultrasonic flow signals by a personal computer. Computers in Biology and Medicine 13(4): 281-286

This paper describes a method of performing spectral analysis on Doppler acoustical signals from peripheral blood vessels with the use of an Apple II plus personal computer. Digitization is accomplished with a commercially available analog-to-digital converter. The data are transformed with a fast Fourier technique, and the resultant information is plotted by an inexpensive X-Y plotter and/or on a television receiver.

A rapid decrease in the translational efficiency of mRNA synthesized during vegetative growth is associated with the initiation of development in Dictyostelium discoideum. In contrast, newly synthesized mRNA associates with polysomes with high eff...

The sulfur supply of agricultural crops plays an important role in their defence strategies against pathogens. The mechanisms of sulfur-induced resistance (SIR) are, however, not yet known. The working hypothesis was the involvement of volatile su...
