Comparison Between Vacuum and SF6

In an SF6 circuit-breaker, the current continues to flow after contact separation through the arc whose plasma consists of ionized SF6 gas. For, as long as it is burning, the arc is subjected to a constant flow of gas which extracts heat from it.

Ozone layer - Wikipedia

2018-9-12The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), nitrous oxide (N 2 O), hydroxyl (OH), atomic chlorine (Cl), and atomic bromine (Br). While there are natural sources for all of these species, the concentrations of chlorine and bromine increased markedly in recent decades because of the release of large

4.1 Elements of Fission Weapon Design

2018-5-19By the time the flying plate converges from a radius of 10-20 cm to collide with the levitated core, it is no longer a thin shell. The velocity difference that is inherent in thick shell collapse leads to a collision velocity of the inner surface that is higher than the average plate velocity.

2018-9-14<p>Some types of birds, mostly storks, choose the high parts of MV and LV poles to build their nests during nesting season (January to April). Storks have been identified as responsible for shooting the lines, either because they touch the lines with the wings or because wood sticks or other materials fall from the nests that they build in

Understanding California''s Cap-and-Trade

2015-2-3Overview. California is in the process of implementing the most aggressive cap-and-trade scheme in the United States. This effort is part of California’s plan under the California Global Warming Solutions Act (AB32) to bring statewide emissions down to 1990 levels by 2020. At its peak, California’s cap-and-trade program will cover roughly
