Han and Griffith (1965a) developed a modified version of an ebullition cycle and, using a simplification in the temperature profile equation, they obtained an explicit form for the waiting period ... 

To calculate the total ebullition cycle time, the length of the bubble growth period, 0rf, is also needed, which can be estimated by first estimating the bubble diameter at the time of departure and then estimating the time for the bubble to grow to that size, as will be discussed in later sections. 

For liquid metals the superiority of nucleate boiling heat transfer coefficients over those for forced-convection liquid-phase heat transfer is not as great as for ordinary liquids, primarily because the liquid-phase coefficients for liquid metals are already high, and the bubble growth period for liquid metals is a relatively short fraction of the total ebullition cycle compared with that for ordinary fluids. In the case of liquid metals, the initial shape of the bubbles is hemispheric, and it becomes spherical before leaving the heating surface. This is because of very rapid...

Storage of sulfur in lake sediments results from cycling of S in the lake water and postdepositional diagenetic processes in sediments. The major features of S cycling in lakes are well known. Sulfur is a macronutrient uptake by phytoplankton and subsequent burial of organic S in sediments occur in all lakes (23, 62, 63). Putrefaction of organic S releases H2S (as well as trace amounts of other S gases 64-66) that is either fixed in sediments as iron sulfides, lost to the atmosphere via diffusion or ebullition, or oxidized.
