High intensity ultraviolet radiation induced changes in aquatic arthropod with retene and riboflavin

Environment Conservation Journal, 2011
Ozone depletion is resulting into increase in ultraviolet radiation level in the world. Exposure to UV radiation has been found to have negative effects on aquatic and terrestrial organisms.

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 ...

Hawking Radiation and Ultraviolet Regulators [PDF]

, 1995
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.

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 ...

Far Ultraviolet Diffuse Emission from the Large Magellanic Cloud

, 2010
We present the first observations of diffuse radiation in the far ultraviolet (1000 -- 1150 \AA) from the Large Magellanic Cloud based on observations made with the {\it Far Ultraviolet Spectroscopic Explorer}.

EFFECT OF ULTRAVIOLET RADIATION ON THE COLOR OF FREIJÓ WOOD (Cordia goeldiana Huber) AFTER APPLICATION OF FINISHING PRODUCTS

Ciência Florestal, 2010
Ultraviolet radiation is considered the most damaging radiation to wood, affecting its properties and especially its color. The application of finishing products such as varnishes, stains and inks can minimize the action of this radiation.

Habitable Zones and UV Habitable Zones around Host Stars

, 2010
Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along.
