Ratios of UV, PAR and NIR components to global solar radiation measured at Botucatu site in Brazil
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The relationships between the four radiant fluxes are analyzed based on a 4 year data archive of hourly and daily global ultraviolet (I(UV)), photosynthetically active-PAR (I(PAR)), near infrared (I(NIR)) and broadband ...
QTL for survival to UV-C radiation in Drosophila melanogaster
(Taylor & Francis, 2012-08)
Purpose: The aim of this study was to investigate tolerance to UV-C (ultraviolet C, 280–100 nm) radiation in Drosophila melanogaster, implementing a quantitative trait locus (QTL) mapping approach. This is of interest to ...
ULTRAVIOLET TECHNOLOGY FOR FOOD PRESERVATION
(Centro Pesquisa Processamento AlimentosCuritiba PrBrasil, 2009)
Anticlastogenic effect of β-glucan, extracted from Saccharomyces cerevisiae, on cultured cells exposed to ultraviolet radiation
β-glucan is an important polysaccharide due to its medicinal properties of stimulating the immune system and preventing chronic diseases such as cancer. The aim of the present study was to determine the anticlastogenic ...
Ultraviolet radiation enhances Arctic net plankton community production
(São Francisco, 2014-08-25)
In this study we report the response of net community production (NCP) of plankton communities in the Arctic surface waters exposure to natural ultraviolet radiation (UVR) conditions. A possible bias in previous measurements ...
Sensitivity of winter phytoplankton communities from Andean lakes to artificial ultraviolet-B radiation
(Sociedad de Biología de Chile, 2001)
Effects of UV-B radiation on Lecanicillium spp., biological control agents of the coffee leaf rust pathogen.
(Tropical Plant Pathology, Brasília, DF, v. 39, n. 5, p. 392-400, 2014., 2014)
Effect of ultraviolet-B (UV-B) radiation on bacterial community in the soybean phyllosphere.
(African Journal of Microbiology Research, Sapele, v. 8, n. 31, p. 2916-2923, 2014., 2014)
In situ Responses of Phytoplankton from the Subtropical Lake La Angostura (Tucumán, Argentina) in Relation to Solar Ultraviolet Radiation Exposure and Mixing Conditions
In situ experiments were conducted at various depths in the water column to determine the effects of solar ultraviolet radiation (UVR, 280–400 nm) on photosynthesis of natural phytoplankton assemblages from the subtropical ...
