The emission spectra for FAM and VIC peak at 517nm (in the blue region of the visible spectrum) and 551nm (in the green region) respectively (Figure 1), making these wavelengths easily distinguishable by any Applied Biosystems real time PCR instrument. Top Three...
light, is a color in the visible light spectrum that can be seen by human eyes. it's emitted by many digital devices, including computers, tablets, and smartphones. while it does have benefits such as boosting attention and mood during daylight hours, prolonged exposure can potentially have ...
Broad-line radio galaxies show broad-line light emissions from ionized oxygen, hydrogen, and silicon in their optical spectrum. Narrow-line radio galaxies are AGNs that lack broad-line emissions but have narrow emission lines from hydrogen and triplely-ionized oxygen. What is the difference ...
Flame colors span a spectrum that tells a tale as old as fire itself. Many people wonder what color is the hottest flame; more than a testament to the natural fascination with fire's beauty, this question underscores a fundamental principle in the scienc
Before we get into the details of describing a spectrum analyzer, we might first ask ourselves: “Just what is a spectrum and why would we want to analyze it?” Our normal frame of reference is time. We note when certain events occur. This includes electrical events. We can use an oscil...
EMI is a disruption induced by an electromagnetic disorder that affects a device’s output. EMI may be natural sources, such as electrical storms and solar rays, but other computer devices or electrical systems may normally be more essential. If the disturbance occurs in the spectrum of radio ...
A positron emission tomography imaging study, conducted while subjects performed a passive viewing task,122 found repetition suppression of cerebral blood flow in the right hemisphere of normal individuals across presentations of the same visual image as expected, but in patients with schizophrenia the ...
the intensity of the γ-ray emission and the presence of Compton-scattered γ rays in the energy window of the peak selected for imaging. An energy window of 10% interval around the peak barycenter was chosen. To evaluate the influence of Compton-scattered γ rays on the final quality of ...
Then I suddenly remember Dennis Gabor, inventing holography before lasers existed. To create his pseudo-lasers he just took light from an ordinary mercury-arc lamp and passed it through a pinhole. Mercury's emission line made it nearly monochromatic, and the pinhole gave it the spatial coherence...
An energetic barrier that does not allow free movement in and out of the space surrounding earth has us spiritually bottled up here, endlessly repeating cycles of death and birth and sometimes very interesting but always short lives. We are forced to lead our lives of “three score and ten”...
