Also, plant growth and development are adversely impacted by oxidative damage caused by UV-B rays [32]. Cells respond to oxidative stress by triggering some defence mechanisms that lessen damage and help the body return to equilibrium. Upregulating antioxidant enzymes, which mitigate ROS and lessen ...

Accordingly, it is now required to take measures such that the ultraviolet rays of the above-described wavelength ranges are also absorbed by the glass to prevent their radiation to the outside of the lamp. In a case where a conventional borosilicate glass is used for the outer tube of a ...

It is shorter than radiation in the visible spectrum but longer than X-rays. The ultraviolet spectrum is also subdivided due to each band’s effect on the biosphere [3]: UV-A—wavelengths: 315–400 nm; UV-B—wavelengths: 280–315 nm; UV-C—wavelengths: 100–280 nm. The sun emits ...
While UVB and UVC photons are substantively absorbed in the epidermis, UVA rays can penetrate into the dermis. In a short time interval, UV radiation contributes to the formation of vitamin D in the skin, has a bactericidal effect (primarily UVC), and at high doses can lead to the ...
