Figure 2 and Figure 3 show the size distribution of these ultrafine particles measured by separate single screens (EML), stacked single screen (USBM), and the mobility analyzer (UI). 

The following forecast, (Table 1), based on published information by J. Shelton of the USBM (1), was used to predict the sulfur demand to the year 2000. The figures chosen on the top line are for probable demand based on a probable average annual growth rate of 4.3 percent between 1978 and 2000. The bottom line figures are for a growth rate of 2.3 percent annually. 

U.S. Bureau of Mines (36,32). The industrial use of sulfur concretes in corrosive environments has been pioneered by the U.S. Bureau of Mines. In cooperation with metal smelting and fertilizer industries USBM has installed test sections of SC in several locations where PCC deteriorates in a matter of a few months.

PTFE-treatment on GDM wettability in terms of the US Bureau of Mines (USBM) wettability index.26 The USBM wettability index compares the amount of work required for water injection to that for water withdrawal and is highly sensitive for intermediately wet systems. This approach proved to be particularly sensitive to slight changes in wettability caused by PTFE addition.
