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.
Gas lighter. A gas lighter is a device which is used to ignite the gas stove. It is used in gas stoves which do not have automatic ignition systems. It uses a physical phenomenon called piezo-electric effect to generate an electric spark which ignites the combustible gas from the stove burner.
