Gaseous dielectric | Wikipedia audio article

A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc. A good dielectric …

Liquefied Natural Gas Safety and Emergency Response

Liquefied Natural Gas Safety and Emergency Response

Narrator: AN LNG VESSEL FULL OF MORE THAN 100,000 CUBIC METERS OF LIQUEFIED NATURAL GAS MAKES ITS WAY TO A TERMINAL. THE U.S. COAST GUARD HAS SPECIFICALLY AUTHORIZED THIS DELIVERY, AND MAINTAINS A SAFETY AND SECURITY ZONE AROUND THE TANKER. NO OTHER VESSELS ARE ALLOWED TO ENTER THE ZONE. ONCE THE SHIP IS DOCKED, THE …

Fluorocarbon

Fluorocarbon

Fluorocarbons, sometimes referred to as perfluorocarbons or PFCs, are, strictly speaking, organofluorine compounds with the formula CxFy, i.e. they contain only carbon and fluorine, though the terminology is not strictly followed. Compounds with the prefix perfluoro- are hydrocarbons, including those with heteroatoms, wherein all C-H bonds have been replaced by C-F bonds. Fluorocarbons and their …

Socio-Environmental Systems In Transition

I think one of the biggest lessons I learned during this symposium was from the people who tend to work over long time periods and what they reminded us is that communities are always in transition Tamara Ticktin talked about the incredibly agrodiverse fields of communities in Fiji and she said we know these systems …

Environmental issues in Sri Lanka | Wikipedia audio article

Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Insufficient waste management, especially in rural areas, leads to environmental pollution. Sri Lanka is also vulnerable to climate change impacts such …
