Journal of Applied Sciences and Environmental Management, 2023 Welding goggles provide a degree of eye protection while some forms of welding and cutting are being done. They are intended to protect the eyes not only from the heat and optical radiation produced by the welding, such as the intense ultraviolet light ...

Hawking radiation and ultraviolet regulators [PDF]
Physical Review D, 1996 Polchinski has argued that the prediction of Hawking radiation must be independent of the details of unknown high-energy physics because the calculation may be performed using `nice slices', for which the adiabatic theorem may be used. If this is so, then any calculation using a manifestly covariant --- and so slice-independent --- ultraviolet ...

ULTRAVIOLET RADIATION DISINFECTION FOR SARS-COV-2
International Journal of Infectious Diseases, 2023 Intro: COVID-19 pandemic affected the entire globe and resulted in millions of deaths. Besides human-to-human respiratory droplets transmission, contact with aerosol-infected surfaces is an important way of transmitting this virus.

Metal-rich stars are less suitable for the evolution of life on their planets
Nature Communications, 2023 Atmospheric ozone and oxygen protect the terrestrial biosphere against harmful ultraviolet (UV) radiation. Here, we model atmospheres of Earth-like planets hosted by stars with near-solar effective temperatures (5300 to 6300 K) and a broad range of ...

Ultraviolet radiation changes plant color
BMC Plant Biology, 2020 Background Plant absorption of ultraviolet (UV) radiation can result in multiple deleterious effects to plant tissues. As a result, plants have evolved an array of strategies to protect themselves from UV radiation, particularly in the UV-B range (280 ...

Ultraviolet Background Radiation
Annual Review of Astronomy and Astrophysics, 1973 The results are reported of observations in narrow bands centered on 1115, 1425, and 1446 A of the flux from an empty high-galactic-latitude region and from several stars. The observations had been obtained with the aid of three ultraviolet-sensitive Geiger counters which were carried on an Aerobee-150 rocket launched from the White Sands missile ...
