What is a Fourier power spectrum?
What is a Fourier power spectrum? The power spectrum of a time series. describes the distribution of power into frequency components composing that signal. According to Fourier analysis, any physical signal can be decomposed into a number of discrete frequencies, or a spectrum of frequencies over a continuous range. What is voltage spectrum? VSpec calculates […]

Is reduction Exergonic or Endergonic?
Is reduction Exergonic or Endergonic? The dehydrogenase enzyme reduces acetaldehyde to ethanol, which is an endergonic (energy-requiring) reaction: The reduction of acetaldehyde is coupled to the oxidation of NADH to NAD+, which is an exergonic reaction. Do oxidation and reduction always occur together? So oxidation and reduction always occur together; it is only mentally that […]

Is 60 gigahertz harmful to humans?
Is 60 gigahertz harmful to humans? In addition to the very low power levels discussed above, 60 GHz systems do not penetrate the human body. As a result, exposure to 60 GHz is very similar to the exposure to sunlight ” but at 1/10,000 of the energy. Lower-frequency emissions penetrate and may even pass completely […]
