A model to extend spectral and multiwavelength UV irradiances time series: Model development and validation
(American Geophysical Union, 2003-12)
Measurements of spectral and multichannel UV radiation became more common in the middle and late eighties after the discovery of the ‘‘ozone hole,’’ but time series for these measurements are still relatively short for the ...
An increase in the concentration of abscisic acid is critical for nitric oxide-mediated plant adaptive responses to UV-B irradiation
(Wiley Blackwell Publishing, Inc, 2009-12)
• Here, the link between UV-B stimulus and the abscisic acid (ABA)-induced nitric oxide (NO) synthesis pathway was studied in leaves of maize (Zea mays). • The ABA concentration increased by 100% in UV-B irradiated leaves. ...
Role of UV-C irradiation scheme on cell wall disassembly and surface mechanical properties in strawberry fruit
(Elsevier Science, 2019-04)
UV-C treatments have been reported to prevent frmness loss and decay in part by delaying the degradation of fruit structural barriers. The influence of the irradiation regime on wall disassembly has not been determined. We ...
Relationship between erythemal UV and broadband solar irradiation at high altitude in Northwestern Argentina
(Pergamon-Elsevier Science Ltd, 2018-11)
An analysis of the broadband solar irradiation, IT, and the erythemal UV irradiation, IUVER, has been performed using the measurements made from 2013 to 2015 at three sites located at altitudes over 1000 m a.s.l. In ...
UV radiation effects and bioaccumulation of UV-absorbing compounds in Artemia persimilis larvae
(PanamJas, 2016-07)
The aims of this study were to determine if larvae of Artemia persimilis (Crustacea: Branchiopoda) can bioaccumulate ultraviolet radiation (UVR) absorbing compounds like mycosporine-like aminoacids (MAAs) through the diet ...
A long term study of the relations between erythemal UV-B irradiance, total ozone column, and aerosol optical depth at central Argentina
(Pergamon-Elsevier Science Ltd, 2017-09)
Global ultraviolet-B irradiance (UV-B, 280–315 nm) measurements made at the campus of the University of Córdoba, Argentina were analyzed to quantify the effects of ozone and aerosols on surface UV-B erythemal irradiance ...
Rad51 prevents Mre11-dependent degradation and excessive primpol-mediated elongation of nascent DNA after UV irradiation
(National Academy Of Sciences, 2015-12)
After UV irradiation, DNA polymerases specialized in translesion DNA synthesis (TLS) aid DNA replication. However, it is unclear whether other mechanisms also facilitate the elongation of UV-damaged DNA. We wondered if ...
Estimated and measured DNA, plant-chromosphere and erythemal-weighted irradiances at Barrow and South Pole (1979-2000)
(Elsevier Science, 2003-12)
In the last two decades as a consequence of ozone depletion there has been an increasing interest in the study of biological effects of ultraviolet radiation (UV). Spectral instruments, which provide detailed information ...
UV-A (315–400nm) irradiance from measurements at 380nm for solar water treatment and disinfection: Comparison between model and measurements in Buenos Aires, Argentina and Almería, Spain
(Pergamon-Elsevier Science Ltd, 2009-02)
A linear correlation between UV-A and 380 nm was developed by means of the TUV 4.1 radiative transfer model. The prediction error of the correlation was evaluated with data from Buenos Aires, Argentina, 2001, and from 2006, ...
