Chlorophyll metabolism has been extensively studied with various organisms, and almost all of the chlorophyll biosynthetic genes have been identified in higher plants. However, only the gene for 3,8-divinyl protochlorophyllide a 8-vinyl reductase (DVR), which is indispensable for monovinyl chlorophyll synthesis, has not been identified yet. In this study, we isolated an Arabidopsis thaliana mut...

Edwards A, Layton AT. Impact of nitric oxide-mediated vasodilation on outer medullary NaCl transport and oxygenation. Am J Physiol Renal Physiol 303: F907–F917, 2012. First published July 11, 2012; doi:10.1152/ajprenal.00055.2012.—The present study aimed to elucidate the reciprocal interactions between oxygen (O2), nitric oxide (NO), and superoxide (O2 ) and their effects on vascular and tubula...

In this paper, a second order sliding mode control scheme is utilized for outer voltage loop of three-phase fault current limiter-based dynamic restorer (FCL-DVR) instead conventional proportional integral/proportional resonance (PI/PR) controller. The new strategy improves the performance FCL-DVR against distortion. Furthermore, by using proposed robustness controller, can smoothly switch betw...

Power quality is one of major concerns in the present. It has become important, especially with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. Power quality problem is an occurrence manifested as a nonstandard voltage, current frequency that results in a failure of end use equipments. To solve this problem, custom power devices are...

Voltage sags/swells and harmonics are recurring problems in electric energy distribution systems. In order to solve these issues, several dynamic voltage restorer (DVR) topologies, such as the conventional three-wire DVR, have been proposed literature. Despite its capability of mitigating disturbances, many researchers established that DVR cannot compensate for zero sequence disturbances. this ...

According to the coordination control of a dynamic voltage restorer (DVR) and an inductive fault current limiter (FCL), this paper proposes efficient low-voltage ride-through (LVRT) scheme for doubly fed induction generator (DFIG) based wind turbine. The DVR is located DFIG’s stator circuit stabilizing terminal decreasing current. FCL connected rotor suppressing overcurrent protecting converter...
