The study aims to investigate the effect of repetitive ultraviolet irradiation (UV–UV) and the combination effect with dimethyl dicarbonate (UV–DMDC–UV) on the physico-chemical properties and microbiological stability of pineapple juice. UV dosages of 10.76 mJ/cm2 percycle and 250 ppm of DMDC were used. There was a significant decrease in turbidity, total phenolic and vitamin C in the treated j...

BACKGROUND Estimates of an individual's cumulative ultraviolet (UV) radiation exposure can be useful since ultraviolet radiation exposure increases skin cancer risk, but a comprehensive tool that is practical for use in the clinic does not currently exist. The objective of this study is to develop a geographically-adjusted tool to systematically estimate an individual's self-reported cumulative...

the trend of sustainable use of available water resources encourages textile finishing enterprisesto implement efficient wastewater treatment technologies that enable water recycling, and not just it’sdischarging into the local wastewater treatment plants (wwtp). this paper presents the results obtainedfrom the h2o2/uv treatment of wastewater from slovene textile finishing company. laboratory s...

Cataract is the leading cause of blindness in the world, accounting for nearly half of the 38 million cases of blindness worldwide. Age-related cataract is a multifactorial disease, and the prevalence of cataract approximately doubles with each decade after the age of 30. For this reason, if an intervention were able to delay the onset of cataract by 10 years, the number of cataract operations ...

We present far-ultraviolet spectra of the Seyfert 1.5 galaxy NGC 5548 obtained in 2000 June with the Far Ultraviolet Spectroscopic Explorer (FUSE). Our data span the observed wavelength range 915–1185 Å at a resolution of ∼ 20 km s. The spectrum shows a weak continuum and emission from O VI λλ1032,1038, C III λ977, and He II λ1085. The FUSE data were obtained when the AGN was in a low state, wh...

Fluorescent brighteners increase insect viral activity and provide protection against UV inactivation. The relative amount of viral UV protection has not previously been determined due to the dual nature of these compounds. In this study, two distinct viral–host systems, a nuclear polyhedrosis virus of the gypsy moth (Lymantria dispar) infecting its homologous host and a nuclear polyhedrosis vi...
