UV-radiation effects on photosynthesis, photosynthetic pigments and UV-absorbing substances in three species of tropical lotic macroalgae
(Brazilian Soc Plant Physiology, 2018-09-01)
Freshwater algae inhabiting shallow waters are most effectively affected by UV radiation. The aim of this study was to analyze the photosynthetic performance (parameters derived of chlorophyll fluorescence), chlorophyll a ...
UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2014)
Short-term UV-B radiation affects photosynthetic performance and antioxidant gene expression in highbush blueberry leaves
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2016)
A sensibilidade das plantas de girassol (Helianthus annuus L.) à radiação UV-B é alterada pelo suprimento de nitrogênio
(2018-01-01)
Interaction effects between nitrogen and UV-B radiation were studied in sunflower (Helianthus annuus L. variety IAC-Iarama) plants grown in a greenhouse under natural photoperiod conditions. Plants were irradiated with ...
Use of high-intensity ultrasound and UV-C light to inactivate some microorganisms in fruit juices
(Springer, 2010-12)
Novel technologies that involve non-thermal processes have been investigated in the last two decades as full or partial alternatives to conventional heat treatment. The main objective of this study was to evaluate the ...
Precision improvement for omeprazole determination through stability evaluation
(John Wiley & Sons Inc, 2012-01)
A new spectrofluorimetric method for the determination of omeprazole (OMP) based on its degradation reaction catalyzed by ultraviolet (UV) light is proposed. OMP in aqueous solution is very unstable, which renders a serious ...
Repression of Growth Regulating Factors by the MicroRNA396 Inhibits Cell Proliferation by UV-B Radiation in Arabidopsis Leaves
(American Society of Plant Biologist, 2013-09)
Because of their sessile lifestyle, plants are continuously exposed to solar UV-B radiation. Inhibition of leaf growth is one of the most consistent responses of plants upon exposure to UV-B radiation. In this work, we ...
Respostas fisiológicas de macroalgas continentais à radiação ultravioleta
(Universidade Estadual Paulista (Unesp), 2017-06-23)
Nos últimos séculos a história do ser humano no planeta Terra tem sido marcada por intensos impactos ambientais antropogênicos negativos, dentre os quais destaca-se a maior exposição da radiação ultravioleta (UV) na ...
