Corticosteroids are also used supportively to prevent nausea, often in combination with 5-HT3 antagonists (e.g. ondansetron). Typical undesired effects of glucocorticoids present quite uniformly as drug-induced Cushing's syndrome.
Common causes. A gas explosion occurs when the gas/air mixture reaches a critical value, then any spark, flame or heat source can ignite the mixture. The explosion is caused when the rapidly expanding, burning gas is confined and builds up pressure. As the pressure builds, something has to give, and in a home gas explosion it is usually the windows.
The remnant of a supernova explosion is a glowing filamentary nebula of, generally, symmetric shape. In a supernova explosion a star ejects a substantial part of its mass (about 1 solar mass) at a speed of about 10,000 km/sec. The resulting spherically symmetric shock wave travels through the interstellar gas.
