Synchronous dimming control for a cold- cathode fluorescent lamp driver - Electronics Letters
lation is created of randomly transformed copies of the original DFG. A fitness is allocated to each member of the population. This is determined by calculating the supply voltage and effective capacitance of the DFG. Area requirements are computed for the adders, delays and multipliers. The total required area is used to estimate the effective capacitance. The GA selects a member of the popula...
متن کاملCases of acute mercury poisoning by mercury vapor exposure during the demolition of a fluorescent lamp factory
BACKGROUND In 2015, workers dismantling a fluorescent lamp factory in Korea were affected by mercury poisoning from exposure to mercury vapor. CASE PRESENTATION Eighteen out of the 21 workers who participated in the demolition project presented with symptoms of poisoning and, of these, 10 had persistent symptoms even at 18 months after the initial exposure to mercury vapor. Early symptoms of ...
متن کاملFrequency domain fluorimetry using a mercury vapor lamp
Frequency Domain (FD) fluorimetry, capitalizes on the frequency response function of a fluorophore and offers independence from light scatter and excitation/emission intensity variations in order to extract the sample's fluorescent lifetime. Mercury vapor lamps, a common source of industrial facility lighting, emit radiation that overlaps the UV/blue absorption spectrum of many fluorophores and...
متن کاملTwo Phase Heat Transfer Characteristics in a Vertical Small Diameter Tube at Sub Atmospheric Pressure
Two-phase heat transfer is experimentally examined through vertical small diameter tubes, D =1.45 and 2.8 mm using water under a pressure of 50 to 81 kPa and a natural circulation condition. The pool boiling correlation by Stephan-Abdelsalam and the thermosyphon boiling correlation by Imura, et al. predict the measured experimental data in the 2.8 mm tube with an error of -30%. A large heat tra...
متن کاملoccupational exposure to mercury among workers in a fluorescent lamp factory, quisna industrial zone, egypt
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 ...
