Effects of radiation patterns from ultraviolet light-emitting diodes on the uniformity of the radiation field in surface disinfection

Fushe yanjiu yu fushe gongyi xuebao
When ultraviolet light-emitting diodes (UV-LEDs) are used for surface disinfection, the UV dose in some areas may exceed the required level but be insufficient in other areas.

Balancing the solar irradiance needs: optimising growth in sphagnum palustre through tailored UV-B effects

BMC Plant Biology
Background The carbon sequestration potential and water retention capacity of peatlands are closely linked to the growth dynamics of Sphagnum mosses. However, few studies have focused on the response of Sphagnum moss growth dynamics to UV-B radiation ...

Variability and the X-ray/UV ratio of Active Galactic Nuclei [PDF]

, 2010
The observed relation between the X-ray radiation from AGNs, originating in the corona, and the optical/UV radiation from the disk is usually described by the anticorrelation between the UV to X-ray slope alpha_ox and the UV luminosity.

X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations

, 2011
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light sources on the hydrogen and helium reionization of the
