Ultraviolet germicidal irradiation
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses ultraviolet (UV) light at sufficiently short wavelength to kill microorganisms. It is used in a variety of applications, such as food, air and water purification. UV has been a known mutagen at the cellular level for more than one-hundred years. The 1903 Nobel Prize for Medicine was awarded to Niels Finsen for his use ...
متن کاملSize and UV germicidal irradiation susceptibility of Serratia marcescens when aerosolized from different suspending media.
Experimental systems have been built in laboratories worldwide to investigate the influence of various environmental parameters on the efficacy of UV germicidal irradiation (UVGI) for deactivating airborne microorganisms. It is generally recognized that data from different laboratories might vary significantly due to differences in systems and experimental conditions. In this study we looked at...

15 صفحه اولEnhanced DDB2 expression protects mice from carcinogenic effects of chronic UV-B irradiation.
UV-damaged DNA-binding protein (UV-DDB) is essential for global genome repair (GGR) of UV-induced cyclobutane pyrimidine dimers (CPD). Unlike human cells, rodent epidermal cells are deficient in GGR of CPDs and express a subunit of UV-DDB, DDB2, at a low level. In this study, we generated mice (K14-DDB2) ectopically expressing mouse DDB2 at elevated levels. Enhanced expression of DDB2 both dela...
متن کاملEngineering Au Nanoparticle Arrays on SiO2 Glass by Pulsed UV Laser Irradiation
We study semi-regular arrays of Au nanoparticles (NP) obtained via UV laser irradiation of thin Au films on glass substrate. The NP structures are prepared from films of a thickness up to 60 nm produced by discharge sputtering or pulsed laser deposition, and annealed by nanosecond laser pulses at 266 or 308 nm, respectively, at fluencies in the range of 60-410 mJ/cm2. For the rare- and close-pa...
