- Hansen collaborated with Larry Travis and other colleagues in a 1979 " Science " article that reported on the development and variability of clouds in the ultraviolet spectrum.
- The product of the oxidase reaction was determined to be 2, 3, 6-tri-hydroxypyridine because of the results of the stoichiometry as well as the results of the ultraviolet spectrum.
- Davidsen's career included developing the first rocket-borne telescope to to obtain the ultraviolet spectrum of a quasar, work that helped answer fundamental questions about the nature of these enigmatic objects.
- In fact, most Cherenkov radiation is in the ultraviolet spectrum; the sensitivity of the human eye peaks at green, and is very low in the violet portion of the spectrum.
- This high end of the ultraviolet spectrum with energies in the approximate ionization range, is sometimes called " extreme UV . " Ionizing UV is strongly filtered by the Earth's atmosphere ).
- As it expands, the amount of energy in the shock wave drops according to the inverse square law, while additional energy is lost through direct radiation in the visible and ultraviolet spectrum.
- To make observations of a part of Jupiter's ultraviolet spectrum not covered by other instruments, NASA will launch a sounding rocket from White Sands, N . M ., just before the comet hits.
- His work on ultraviolet spectrums and other types of astronautical tools helped him earn the Black Engineer of the Year award, of which he was one of the first 100 people to receive.
- Davidsen, among other things, developed a rocket-borne telescope in the 1970s that obtained the first ultraviolet spectrum of a quasar, leading to a new theoretical understanding of conditions inside these highly-energetic and enigmatic objects.
- It is generally assumed that the " DU " in the name was a combination of " D " for the Model D on which it was based, and " U " for the ultraviolet spectrum.
- Of note, the S1 photocathode had sensitivity peaks in both the infrared and ultraviolet spectrum and with sensitivity over 950 nm was the only photocathode material that could be used to view infrared light above 950 nm.
- Also consider, for example, lepidoptera-butterflies-who ID flowers in the ultraviolet spectrum; the patterns and colors in the UV wavelength are drastically different than how we see them . Wolfgangus 05 : 54, 25 October 2006 ( UTC)
- While the part of the ultraviolet spectrum that penetrates the Earth's atmosphere is non-ionizing, this radiation does far more damage to many molecules in biological systems than can be accounted for by heating effects, sunburn being a well-known example.
- WASHINGTON _ Richard Tousey, a solar physicist who used a captured World War II V-2 rocket to take the first photographs of the Sun's ultraviolet spectrum from beyond the atmosphere, died Tuesday at Prince George's Hospital Center in Maryland.
- In general, ionizing radiation is all forms of particle radiation, as well as photons that have high enough energy to ionize ( which includes a portion of the ultraviolet spectrum as well as X-ray and gamma ray energy ).
- It carried four instruments with which scientists at the University of California at Berkeley's Space Sciences Laboratory surveyed the entire Milky Way galaxy _ and beyond _ for objects radiating their energy at the unexplored far end of the ultraviolet spectrum.
- A good example is ultraviolet spectrum energy which begins at about 3.1 eV ( 400 nm ) at close to the same energy level which can cause sunburn to unprotected skin, as a result of photoreactions in collagen and ( in the UV-B range ) also damage in DNA ( for example, pyrimidine dimers ).
- For example, for a given " B-V " index from the blue-visible region of the spectrum ., the curves for both types of star lie below the corresponding black-body " U-B " index that includes the ultraviolet spectrum, showing that both types of star emit less ultraviolet light than a black body with the same " B-V " index.
- Some of the ultraviolet spectrum that does reach the ground ( the part that begins above energies of 3.1 eV, a wavelength less than 400 nm ) is non-ionizing, but is still biologically hazardous due to the ability of single photons of this energy to cause electronic excitation in biological molecules, and thus damage them by means of unwanted reactions.
