Results of Irradiating Saccharomyces with Monochromatic Ultra-violet Light
Data obtained on yeast irradiated with monochromatic ultra-violet radiation has been analyzed for the number of quantum hits involved in the production of different degrees of inhibition of cell division, according to the method proposed by Mme. Curie (1929). Sufficient data are not available for a rigorous determination, but the calculated results tend to indicate that a multiple hit to kill r...
متن کاملResults of Irradiating Staphylococcus Aureus Bacteriophage with Monochromatic Ultraviolet Light
The incident energies required to kill Staphylococcus aureus or to inactivate its homologous bacteriophage have been measured at the various wave-lengths of the quartz mercury vapor arc between 238 and 302 mmicro and found to run strictly parallel, the readings for the S. aureus phage being obtained at a uniformly higher energy level. This difference in levels is of less significance than the s...
متن کامل[ . the Effect of Monochromatic Ultra - Violet Light upon Vaccine Virus
I t has been known for many years tha t ul tra-violet light is bactericidal. Finsen and Dreyer (1), in 1903, were probably the first to Show tha t light with short wave-lengths is virucidal also. More recent ly (2-7) other reports have appeared dealing with the effects of ul tra-violet irradiation upon bacteria, viruses, and enzymes. For the most par t , however, single wave-lengths have not be...
متن کاملThe Abiotic Action of Ultra-violet Light
Typhoid bacilli are about one two-hundredth as sensitive to ultraviolet light of wave-lengths 2100 to 2800 Angström units as is the photographic plate. This sensitivity then falls off, decreasing rapidly to almost zero sensitivity at about 2970, the beginning of the sun's spectrum.
متن کاملAn Ultra-violet Light Monitor for Spear3
A synchrotron light monitor is an essential tool for operating a storage ring. For SPEAR3, the upgrade of the SPEAR storage ring, the light monitor was designed not only for monitoring the beam presence but also to measure beam parameters. To minimize diffraction effects, UV light around 200 nm is used to image the electron source rather than visible light. At 200 nm, the rms diffraction spot i...
