Rapid development in electrical technology has imposed strong challenges to modern power system. Power quality become a great concern due proliferation of electronic loads. Specifically for lighting load such as compact fluorescent lamps (CFLs), one the concerning issues is harmonics. CFL cost-competitive and energy efficient compared incandescent lamp. Inevitably, produces harmonics current no...
background: with the fast growth in the market of fluorescent lamps, particularly compact fluorescent light, the associated risk of mercury exposure, which is an essential component in all types of fluorescent lamps, has received increasing public attention worldwide. even low doses of mercury are toxic. objective: to study the health consequences of occupational exposure to mercury in workers ...
In the scope of the monIT Project, it was found that fluorescent and compact fluorescent lamps are also important sources of radiation. More than increasing EMF levels in a particular environment, the radiation from ballasts may cause electronic interference with other devices. Two different lamps are analysed, in terms of both their radiated frequency spectrum and their compliance with Europea...
A reagent-free activation method for the addition of SF5Cl on unsaturated compounds was developed using a blacklight compact fluorescent lamp irradiation. total 19 examples alkenes and alkynes were performed, with yields ranging from 25% to 99%. Overall, this represents an oxygen-free alternative most common reaction conditions.
Background: Nowadays, the rapid recovery of skin lesions and functional return are among the goals of researchers. The skin is the first defensive barrier against microorganisms in the body and its failure causes infection to spread in all systems of the body. By taking into account the contradictory results of previous studies on the impact of phototherapy on wound healing and also the conside...
