UV dose investigation for imersed lamp purifier for electronic ballast UV lamps design
(2014-01-01)
This paper presents a methodology of an electronic ballasts design for UV lamps filtering system, providing adjustable UV dose in order to ensure the inactivation of microorganisms' reproduction that are harmful to human ...
UV Dose Investigation for Imersed Lamp Purifier for Electronic Ballast UV Lamps design
(Ieee, 2014-01-01)
This paper presents a methodology of an electronic ballasts design for UV lamps filtering system, providing adjustable UV dose in order to ensure the inactivation of microorganisms' reproduction that are harmful to human ...
uvsZ1 mutation shows epistatic relations with uvsD153 and uvsJ1 mutations without any involvement with checkpoint control in Aspergillus nidulans

Assessment of empirical models to estimate UV-A, UV-B and UV-E solar irradiance from GHI
(ISES, 2019)
Exposure to the UV solar irradiance reaching the ground has an important impact on human health, vegetable growth and the degradation processes of several materials. As a first step of a larger project aiming to characterize ...
Acclimation to UV irradiance in Gracilaria chilensis Bird, McLachlan & Oliveira (Gigartinales, Rhodophyta)
(Springer Netherlands, 1996)
Photoautotrophs can cope with an increase in ultraviolet (UV) irradiance in the aquatic environment, through protection and acclimation mechanisms (i.e. synthesis of UV-absorbing compounds). This capacity has been proven ...
Estudio de la confiabilidad y validez de la medida de UV del Uv-metro Unisalle
(Universidad de La Salle. Facultad de Ciencias de la Salud. Optometría, 2007)
Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Floral UV Features of Plant Species From a Neotropical Savanna
(Frontiers Media Sa, 2021-05-07)
Despite the wide interest in flower colours, only after the end of the nineteenth-century studies started to comprise floral UV reflection, which is invisible to humans but visible to the major groups of pollinators. Many ...
Effect of UV-B radiation on the photoprotective and antioxidant response in Vaccinium corymbosum L.: An approach to the UV-B resistance mechanisms.
(2017)
Despite the Montreal protocol success and the eventual recovery of the ozone layer over Antarctica, there are still concerns about increased levels of ultraviolet-B (UV-B) radiation in the Southern Hemisphere. It is expected ...
