The histological changes in the ovarioles of the red cotton bug following treatment with "Paper Factor" to the adults are discussed. The changes in the shape of egg, resorption of the yolk and the formation of compound chambers with double nuclei were probably caused through deformation either in the germarium or follicular epithelial cells.
This paper proposed Vienna rectifier which overcome many limitation and reduce harmonics from input mains supply. Vienna rectifier reduce the blocking voltage stress across the semiconductor to reduce the conduction losses and give low total harmonics distortion <5%. Hence improve the power quality and gives unity power factor from supply side. KeywordsMain(More)
