Ultra-violet Light and Vaccine Virus
Rabbit skin treated for a few minutes with ultra-violet light and then inoculated at once with vaccine virus is less susceptible to the action of the virus than is untreated skin. If 24, 48, or 72 hours elapse between the time of irradiation and inoculation, the treated skin appears to be more susceptible than is untreated skin. Skin repeatedly exposed to ultra-violet light is less susceptible ...
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...
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 کاملHeritable glycogen-storage deficiency in yeast and its induction by ultra-violet light.
Cultures of several diploid strains of Saccharomyces cerevisiae were found to contain about 0.5 % of glycogen-deficient cells. Ultraviolet irradiation increased the mutant frequency to about 5 %, while 40 % of the population survived. The mutants were detected by plating cultures on nutrient agar containing I % glucose and staining 3-day colonies with iodine; normal colonies became brown due to...
متن کاملSemiconductor ultra-violet light-emitting diodes for flash photolysis.
'Caged' compounds are biological molecules that are rendered inactive by a protecting (cage) group. Photocleaving of chemical bonds associated with the cage species with intense UV light results in the release of the active molecules. This technique, called flash photolysis, allows for real-time study of interacting biological molecules and typically involves the use of high intensity lasers or...
