Usage examples of ultraviolet.

Against the vibrant, ultraviolet background of the nutritive culture, the aggregation of Thiobacillus glowed brilliantly from their treatment with the acridine orange stain.

Perhaps the solar ultraviolet light could be absorbed by an atmospheric layer of pulverized asteroidal or surface debris injected in carefully titrated amounts above the CFCs.

She preferred the faster and more stable ethidium bromide, even though you needed an ultraviolet trans illuminator to make it fluoresce.

Ultraviolet gives us hereditary mutation and the euchromatin contains the genes that transmit heredity.

Their greatest pleasure was to sit along a girder and open their amplified senses to the depths of space, watching stars past the limits of ultraviolet and infrared, or staring into the flocculate crawling plaque of the surface of the sun, or just sitting and soaking in watts of solar energy through their skins while they listened with wired ears to the warbling of Van Allen belts and the musical tick of pulsars.

We accelerated the reaction on the ninhydrin test with heat and humidification and ran it under the ultraviolet.

One possible explanation: Freshly fallen snows of nitrogen, methane, and other hydrocarbons are irradiated by solar ultraviolet light and by electrons trapped in the magnetic field of Neptune, through which Triton plows.

Exposed to increased irradiation, the reproductive cells of many plankton species, up to six times more susceptible to destruction by ultraviolet light, were gradually being destroyed.

In short order he set up a binocular microscope, a polariscope, and an ultraviolet light on the low coffee table in front of the couch.

But they took her aboard, drenching her with stinging antiseptics, scorching her skin with bactericidal ultraviolet rays.

Anything potent enough to put on such a show could well blow away the magnetosphere, the magnetic zone high above the Earth that normally protects us from ultraviolet rays and other cosmic assaults.

Finding a small ultraviolet penlight, she slipped it in the pocket of her sweater and hurried back up the hallway toward the open doors of the Salle des Etats.

The ionizing ultraviolet that spurred their development and provides them energy also photodissociates them, and they play a game of Scylla and Charbydis with their environment.

Cameras, infrared and ultraviolet spectrometers, and an instrument called a photopolarimeter are on a scan platform that swivels on command so these device can be aimed at a target world.

With waves and tides and hot rocks and solar evaporation to concentrate the amino acids and proteinoids found in the seas and to turn them into the precursors of life, with lightning and heat and radiation and ultraviolet light to turn simple molecules into more complex ones, with the physics and chemistry of the universe itself to produce the necessary elements and simple compounds in appropriate amounts, it may even be said that life on Earth was inevitable, that it had to appear as soon as a microsphere was formed with just the right bit of nucleic acid within itself.
