Optical counterparts of cosmological GRBs due to heating of ISM in the parent galaxy [PDF]
, 1999 We investigated influence of cosmological GRB on the surrounding interstellar medium. It was shown that \gamma-radiation from the burst heats interstellar gas to the temperatures > 10^4 K up to the distance \sim 10 pc. For high density ISM optical and UV

UV-A radiation effects on higher plants: Exploring the known unknown.
Plant Science, 2017 Ultraviolet-A radiation (UV-A: 315-400nm) is a component of solar radiation that exerts a wide range of physiological responses in plants. Currently, field attenuation experiments are the most reliable source of information on the effects of UV-A. Common

Mathematical Assessment of Aerosol Impact on the Diffuse-to-Global Ratio of Solar UV Radiation
MathematicsThis study is devoted to investigating the effect of aerosols on solar UV radiation. In the ultraviolet range, scattering processes are dominant and lead to a substantial contribution of diffuse UV radiation to the global UV irradiance.

Radiative non-isothermal Bondi accretion onto a massive black hole
, 2019 In this paper, we present the classical Bondi accretion theory for the case of non-isothermal accretion processes onto a supermassive black hole (SMBH), including the effects of X-ray heating and the radiation force due to electron scattering and ...

Molecular Hydrogen Emission from Protoplanetary Disks II. Effects of X-ray Irradiation and Dust Evolution [PDF]
, 2007 Detailed models for the density and temperature profiles of gas and dust in protoplanetary disks are constructed by taking into account X-ray and ultraviolet (UV) irradiation from a central T Tauri star, as well as dust size growth and settling toward ...

Episode of unusual high solar ultraviolet radiation over central Europe due to dynamical reduced total ozone in May 2005 [PDF]
, 2006 In late May 2005 unusual high levels of solar ultraviolet radiation were observed over central Europe. In Northern Germany the measured irradiance of erythemally effective radiation exceeded the climatological mean by more than about 20%.

Environmental & health impacts of ultraviolet radiation: current trends and mitigation strategies
Discover SustainabilityContrary to the conventional wisdom and practices moderate non-burning ultraviolet (UV) radiation may be beneficial to our existence, but ecosystems and human health are seriously threatened by the rise in UV radiation from ozone layer loss and climate ...
