EXPERIMENTS ON AN ASH-FREE DIET AND SALT METABOLISM

Simultaneous Ash and Sulphur Removal from Bitumen Using Column Flotation Technique: Experiments, RSM Modeling and Optimization

An efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. The bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. The Box-Behnken Design (BBD) was employed to design the experiments, to ...

Irradiated ergosterol and calcium-free diet: effect on calcium and phosphorus metabolism.

BROWN AND SHOHL [1930] and Watchorn [1930] have shown that large doses of irradiated ergosterol lead to a decreased retention of calcium in rats, in spite of the calcification of certain tissues which takes place at the same time. It has been noted also by Brown and Shohl [1930], Duguid, Duggan and Gough [1930] and by Harris [1930] that the severity of the symptoms of hypervitaminosis D corresp...

Experiments on Free-Surface Turbulence

Ash aggregation enhanced by deposition and redistribution of salt on the surface of volcanic ash in eruption plumes

Interactions with volcanic gases in eruption plumes produce soluble salt deposits on the surface of volcanic ash. While it has been postulated that saturation-driven precipitation of salts following the dissolution of ash surfaces by condensed acidic liquids is a primary mechanism of salt formation during an eruption, it is only recently that this mechanism has been subjected to detailed study....
