Effect of ultraviolet filters on skin superoxide dismutase activity in hairless mice after a single dose of ultraviolet radiation
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Organic sunscreens may decrease their protective capability and also behave as photo-oxidants upon ultraviolet radiation (UVR) exposure. The present study investigated the effect of a cream gel formulation containing the ...
Effects of stratospheric ozone depletion, solar UV radiation, and climate change on biogeochemical cycling: interactions and feedbacks
(Royal Society of Chemistry, 2015-01)
Climate change modulates the effects of solar UV radiation on biogeochemical cycles in terrestrial and aquatic ecosystems, particularly for carbon cycling, resulting in UV-mediated positive or negative feedbacks on climate. ...
Sensitivity of yellow passion fruit plants to ultraviolet-B radiation
(2012)
The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted ...
Effects of ultraviolet radiation (UV) in domestic animals. Review
(INIFAP, 2019)
Solar radiation is necessary for life on Earth. Environmental pollution is contributing to
global climate change, in ways such as degrading the atmospheric ozone layer, vital to
controlling the type and amount of ultraviolet ...
UV-Irradiated Strain of Acidithiobacillus ferrooxidans Improved Copper Bioleaching in Chalcopyrite
(Asce-amer Soc Civil Engineers, 2018-08-01)
Bioleaching is a process that uses microorganisms to perform dissolution of sulfide minerals. Actually, most copper is found as chalcopyrite ore, which is the most abundant form of copper sulfide, but it is recalcitrant ...
The genotoxic effects of DNA lesions induced by artificial UV-radiation and sunlight
(ELSEVIER SCIENCE SA, 2010)
Solar radiation sustains and affects all life forms on Earth. The increase in solar UV-radiation at environmental levels, due to depletion of the stratospheric ozone layer, highlights serious issues of social concern. This ...
Modeling hourly and daily fractions of UV, PAR and NIR to global solar radiation under various sky conditions at Botucatu, Brazil
(Elsevier B.V., 2009-03-01)
In this analysis, using available hourly and daily radiometric data performed at Botucatu, Brazil, several empirical models relating ultraviolet (UV), photosynthetically active (PAR) and near infrared (NIR) solar global ...
UVER and UV index at high altitude in Northwestern Argentina
(Elsevier Science Sa, 2016-10)
Measurements of ultraviolet erythemal radiation (UVER) made during two years at three sites located at altitudes over 1000 m a.s.l. in Northwestern Argentina (Salta, San Carlos, and El Rosal) have been used to estimate and ...
Combined impact of ultraviolet radiation and increased nutrients supply: a test of the potential anthropogenic impacts on the benthic amphipod Amphitoe valida from Patagonian waters (Argentina)
(Frontiers, 2014-08-07)
Experiments were conducted during the Austral Summer of 2014 to determine the effects of increased nutrient input and ultraviolet radiation (UVR) on the food consumption rate (FCR) and food preference in the amphipod ...
