Effects on Light Efficiency in Discharge and Solid-State Lighting Operation, Supplied by No-Sinusoidal Voltage
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-01)
The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
Economic analysis of the implementation of an LED lighting system in a dark house: A case study
(2017-04-01)
The use of the Light Emitting Diode (LED) in broiler chicken production is a trend practically irreversible as it happened with the use of compact fluorescent light (FCL) in substitution of the incandescent lamps. As LED ...
Self-assembly in aqueous solution of amphiphilic graft copolymers from oxidized carboxymethylcellulose
(Elsevier B.V., 2015-06-25)
A series of oxidized carboxymethylcellulose-graft-poly(ethylene glycol)-dodecylamine (0CMC-g-PEG-DDA) was prepared by using an appositely prepared PEG with terminal amino groups and different amounts of DDA. The nanoaggregates ...
