thermal decay

"The radiation signal shows only natural thermal decay, no evidence of ionized plasma or radioactivity."

After the defence of his Master's thesis on the thermal decay of oil-shale, he was elected docent of Organic Chemistry of the University in 1922.

Reaction duration: The 1M concentration used with mossy lumps of solid metal is intended to have reaction speed sufficient to finish dissolving the relatively thick mossy lumps in less time than the thermal decay of your calorimeter.

Laterally extensive diabase sills of molten rock later intruded above and below the carbonate rock layers; commercial grade talc was formed from thermal decay of carbonate rock at its contact with the lowest sill, which covers hundreds of square miles (many hundreds of km2).
