USING RADIO FREQUENCY AND ULTRASONIC ANTENNAS FOR INSPECTING PIN-TYPE INSULATORS ON MEDIUM-VOLTAGE OVERHEAD DISTRIBUTION LINES

Using radio frequency and ultrasonic antennas for inspecting pin-type insulators on medium-voltage overhead distribution lines

This paper summarises the activities undertaken when using antennas (ultrasound and radiofrequency) for identifying insulators in pre-failure state by detecting the noise emitted by the distribution line and correlating this with these insulators (porcelain pin type) dielectric breakdown.This has led to developing low-cost maintenance procedures an

Vibrio parahaemolyticus T6SS2 effector repertoires

ABSTRACTAll strains of the marine bacterium Vibrio parahaemolyticus harbor a type VI secretion system (T6SS) named T6SS2, suggesting that this system plays an important role in the life cycle of this emerging pathogen.Although T6SS2 was recently shown to play a role in interbacterial competition, its effector repertoire remains unknown.Here, we emp
