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.
At an altitude of 1000 km above the planet, the atmosphere is excited by radiation and magnetic influences (and possibly gravity flux) to a temperature of 700Â°C (1260Â°F), but the hydrogen gas is so thin that the actual heat involved is negligible.
