Sentences with phrase «damaging light intensities»

Not exact matches

The Lymphocyte Genome Sensitivity (LGS) test looks at white blood cells and measures the damage caused to their DNA when subjected to different intensities of ultraviolet light (UVA), which is known to damage DNA.

The way to do this was suggested by Howell's finding that in terms of the amount of damage done, the light intensity and exposure time are related in a reciprocal manner.

In other words, the damage caused by a given light intensity in two hours is the same as that caused by double the light intensity in one hour.

«The same damage would be caused if an object was exposed to a lower intensity of light for a longer time.»

That's good for probing delicate samples, such as proteins, than can be damaged by high - intensity light.

For artificial lighting throughout the museum, conservators chose novel bulbs that use ultraviolet LEDs rather than the standard blue ones, and different blends of light - emitting phosphors that better approximate natural light when operated at the low intensity needed to avoid damaging fragile pigments.

Optical fibers generally are not able to transmit ultraviolet light because the short wavelength light can interact with dopants or impurities in the fibers, resulting in so - called «solarization» damage and extreme losses of beam intensity.

Using comparative genomics, the research team noticed that P. destructans lacked a key DNA repair enzyme, prompting them to expose the fungi to DNA damaging agents, including different wavelengths and intensities of UV light.
