Diurnal and annual evolution of UV, PAR and NIR irradiations in Botucatu/Brazil
(Elsevier B.V., 2014-01-01)
This paper describes statistical and climatic analyses of G, UV, PAR and NIR irradiations, and UV/G, PAR/G and NIR/G fractions using a data base obtained from 2001 to 2005 in Botucatu/SP/Brazil. Values of irradiations and ...
High altitude solar UV-B and abscisic acid application increase grape berry antioxidant capacity
(Amer Soc Enology Viticulture, 2015-02)
It has been proposed that ultraviolet-B (UV-B) radiation activates grapevines antioxidant defense system and abscisic acid (ABA) acts downstream in the signaling pathway. Effects of solar UV-B perceived by high altitude ...
The Use of Genetic Algorithms in UV Disinfection of Drinking Water
In order to have drinking water, some countries
have to use chlorine. It is use cause is effective and it’s cheap. An
alternative to this process is the UV disinfection of drinking
water. Most of the devices in the ...
Performance of ZnO nanoparticles for fire retardant and UV protection of pine wood
(2019-01-01)
The aim of this paper was to investigate the influence of zinc oxide (ZnO) nanoparticles on the resistance of pine wood to fire and ultraviolet (UV) radiation. The ZnO nanoparticles were prepared from aqueous zinc nitrate ...
Performance of ZnO Nanoparticles for Fire Retardant and UV Protection of Pine Wood
(North Carolina State Univ Dept Wood & Paper Sci, 2018-01-01)
The aim of this paper was to investigate the influence of zinc oxide (ZnO) nanoparticles on the resistance of pine wood to fire and ultraviolet (UV) radiation. The ZnO nanoparticles were prepared from aqueous zinc nitrate ...
Variations in UV radiation in Chile
(1995)
The first observation of UV global radiation in Chile with a portable multichannel radiometer are reported. Four UV wavelengths are included: 305, 320, 340 and 380 nm. Observation latitudes spanning from 18° to 53 °S allow ...
No evidence of UV cone input to mono- and biphasic horizontal cells in the goldfish retina
(SPRINGER, 2010)
Many animal species make use of ultraviolet (UV) light in a number of behaviors, such as feeding and mating. The goldfish (Carassius auratus) is among those with a UV photoreceptor and pronounced UV sensitivity. Little is ...
The Cramer’s rule for the parametrization of phenol and its hydroxylated byproducts: UV spectroscopy vs. high performance liquid chromatography
(Springer Science and Business Media Deutschland GmbH, 2020-10-02)
A linear algebra theorem like Cramer’s rule was used for the analysis of a system of equations obtained from UV spectroscopy, and results were compared against those obtained from HPLC analysis. This parametrization allowed ...
Understanding UV sensor performance in ZnO TFTs through the application of multivariate analysis
(Ieee, 2018-01-01)
Zinc oxide (ZnO) thin film transistors are well suited to UV sensing application because they absorb predominantly in the UV region due to the wide bandgap (Eg = 3.37 eV) and possess a large exciton binding energy (60 meV) ...
