Volume 1C, Symposia: Gas-Liquid Two-Phase Flows; …

A specifically designed dark flight chaer has been built, where hand hold dragonflies (Pantala flavescens) were released and made to fly nearly parallel to the measurement plane toward a guiding light. Realistic kinematics of the dragonfly wings in free flight were measured by filming with 2 synchronized high-speed video cameras.


BKT: It is a switch which in one direction is used to motor the loco while in other it is used for dy- namic braking. Microprocessor based Control Unit: On-board microprocessors control engine speed, fuel injection, and excitation of the alternator.

Phenomena of the pantograph arcing have become a challenge for the further development of high-speed electrified railway system. Despite of the large attention that has been paid to the radiated

US4690689A - Gas tracer composition and method - …

The invention provides a method for tagging methane by adding thereto one or more of the tracer compounds sulfur hexafluoride and chloropentafluoroethane. The methane being tagged is normally being stored in underground storage fields to provide identity and proof of ownership of the gas. The two tracer compounds are readily detectable at very low concentrations by electron capture gas

Regulations. Q: Does the law require the recycling of my obsolete medium-voltage electrical equipment? A: The Kyoto Protocol has designated SF 6 as a greenhouse gas. Its release to the atmosphere needs to be limited. The strictest regulation is the European Regulation 517/2014. It states that the owner of electrical switchgear containing SF 6 gas shall arrange for the recovery of any residual
