Growth Control of Microbial in Miscible Cutting Fluids Using Ultraviolet Radiation
Considering the issues involved in industrial cutting and machining systems, and, in particular, the problems arising from the use of cutting fluids in these systems, this study presents the results of an analysis that ...
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 ...
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 ...
Color alteration of the paint used for iris painting in ocular prostheses
The purpose of this study was to assess color alteration of the paints used for iris painting in artificial eyes. Five disks of heat cured acrylic resin were confectioned by microwave energy for each paint analyzed, in a ...
ULTRAVIOLET TECHNOLOGY FOR FOOD PRESERVATION
(Centro Pesquisa Processamento AlimentosCuritiba PrBrasil, 2009)
Survival of pigmented freshwater zooplankton, exposed to artificial ultraviolet radiation and two levels of dissolved organic carbon
The increase in penetration of ultraviolet radiation has been reported currently over southern South America. It would affect the photoprotective responses in biotic elements of freshwater ecosystems. An experiment was ...
ACTIVATION OF HMDSO THIN FILMS WITH LOW PRESSURE ARGON PLASMA AND VACUUM ULTRAVIOLET RADIATION

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 ...
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 ...
